22 <title>Applied Pokology: Array boundaries and closures in Poke</title>
23 <guid>http://jemarch.net/pokology-03102019.html</guid>
24 <link>http://jemarch.net/pokology-03102019.html</link>
25 <description> Poke arrays are rather peculiar. One of their seemingly
26 bizarre characteristics is the fact that the expressions
27 calculating their boundaries (when they are bounded) evaluate
28 in their own lexical environment, which is captured. In other
29 words: the expressions denoting the boundaries of Poke arrays
30 conform closures. Also, the way they evaluate may be
31 surprising. This is no capricious. </description>

259 <h2>About GNU Parallel</h2>
260
261 <p>GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel.
262 <br />
263 </p>
264 <p>If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops.
265 <br />
266 </p>
267 <p>GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs.
268 <br />
269 </p>
270 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
271 <br />
272 </p>
273 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
274 <br />
275 </p>
276 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
277 <br />
278 </p>
279 <p> find . -name '*.jpg' |
280 <br />
281 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
282 <br />
283 </p>
284 <p>You can find more about GNU Parallel at: <a href="http://www.gnu.org/s/parallel/">http://www.gnu.org/s/parallel/</a>
285 <br />
286 </p>

355 <h2>About GNU SQL</h2>
356
357 <p>GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries.
358 <br />
359 </p>
360 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.
361 <br />

370 <h2>About GNU Niceload</h2>
371
372 <p>GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.<br />

398 <link>https://meanmicio.org/2021/08/15/gnu-health-emergency-response-in-haiti/</link>
399 <description> <p>Yesterday, yet another devastating earthquake hit the southern area of Haiti. </p>
400
401
402
403 <p>Immediately knowing about the earthquake, we contacted our representative in Haiti, <strong>Pierre Michel</strong> <strong>Augustin</strong>, and started an emergency humanitarian response in coordination with our team in the country . </p>
404
405
406
407 <p>Haiti suffers from recurrent <strong>natural disasters</strong> (hurricanes, earthquakes). In the last years, Haiti has also been a victim of <strong>structural poverty and civil unrest.</strong> Haitians are strong, resilient, noble people. Haiti is the land of the free and the brave (see my post “<em><a href="https://meanmicio.org/2019/04/12/my-trip-to-haiti-the-land-of-the-free-and-the-brave/">My trip to Haiti, the land of the Free and the Brave</a></em>” ), yet it seems like the <strong>world has forgotten about Hait</strong>i.</p>

419 <p>We need emergency response now, but we also need to work on Social Medicine, and tackle the socioeconomic determinants that are the root cause of the structural poverty in Haiti. Only then, our Haitians brothers and sisters will be able to recover the dignity that they deserve, and grow in prosperity. We need to create the conditions, working the local community in the country to strengthen the public health and education system. <a href="https://www.gnuhealth.org">GNU Health</a> is part of this program. </p>
420
421
422
423 <p>Our local representative, engineer Pierre Michel Augustin, has been working in the localization of GNU Health, and by the end of 2021, we will have the GNU Health node fully operational in Limbé. The Haiti GNU Health office will provide training and support to the local and regional health professionals and institutions.</p>

430
431 <p>Natural disasters have a profound impact in the short, medium and long period in any nation. The situation gets much worse when they hit impoverished nations. So, in the short term, we will put all the effort to tackle this emergency and save lives. For the medium and long term, we will continue the GNU Health node in Haiti and building the GNU Health Federation in the country, in cooperation with the local team, academic and health institutions. </p>
432
433
434
435 <p>Creating local capacity is key to make the project sustainable. Resources will be dedicated to build the infrastructure (hardware, network..), but the main focus and effort will be on building local capacity, and training the local team to make them independent and build a sustainable and ethical model.</p>

560 <title>Parabola GNU/Linux-libre: TalkingParabola merged in main ISO and installation medium with installer</title>
561 <guid>tag:parabolagnulinux.org,2021-08-12:/news/talkingparabola-merged-in-main-iso-and-installation-medium-with-installer/</guid>
562 <link>https://parabolagnulinux.org/news/talkingparabola-merged-in-main-iso-and-installation-medium-with-installer/</link>
563 <description> <p>Last year <a href="https://www.archlinux.org/news/accessible-installation-medium/">Arch integrated the features from the TalkingArch project into archiso</a> and some months ago <a href="https://archlinux.org/news/installation-medium-with-installer/">they added an installer into their installation medium</a>. As a result, and with some delay, TalkingParabola was deprecated and we added these features to our ISOs too. They are available in out <a href="https://www.parabola.nu/download/">download page</a> as well.</p>
564 <p>Note that although the OpenRC LXDE ISO has the speech boot option, this only works for CLI. Screen reader support will be added in the future for the GUI and the current installer will be replaced with one based in <a href="https://sourceforge.net/projects/revenge-installer/">Zen Installer</a>.</p> </description>

569 <title>GNU Taler news: Code Blau GmbH deploys first external Taler auditor</title>
570 <guid>https://taler.net/en/news/2021-08.html</guid>
571 <link>https://taler.net/en/news/2021-08.html</link>
572 <description> <article>
573 We received a grant from NLnet foundation with the goal to qualify Code Blau GmbH to act as an external auditor for GNU Taler. To do this, we created a guide that describes how to deploy a Taler auditor and then practiced the steps using the existing Taler exchange deployment at BFH. Code Blau wrote a report detailing all the steps taken. Finally, we have created a draft of the kind of business agreement that Code Blau would enter with banks operating the Taler payment system. We thank CodeBlau for their work, and NLnet and the European Commission's Horizion 2020 NGI initiative for funding this work.

579 <title>GNUnet News: GNUnet 0.15.0</title>
580 <guid>https://gnunet.org/en/news/2021-08-0.15.0.html</guid>
581 <link>https://gnunet.org/en/news/2021-08-0.15.0.html</link>
582 <description> <article id="newspost-content">
583 <h1>
584 GNUnet 0.15.0 released
585 </h1>
586 <p>
587 We are pleased to announce the release of GNUnet 0.15.0.
588 <br />
589 This is a new major release. It breaks protocol compatibility with the 0.14.x versions.
590 Please be aware that Git master is thus henceforth
591 <b>
592 INCOMPATIBLE
593 </b>
594 with
595 the 0.14.x GNUnet network, and interactions between old and new peers
596 will result in issues. 0.14.x peers will be able to communicate with Git
597 master or 0.14.x peers, but some services - in particular GNS - will not be compatible.
598 <br />
599 The MESSENGER service goes out of experimental to be used by
600 libraries and applications as dependency. It handles decentralized
601 messaging in flexible groups by using the CADET service and messages
602 can be signed with your ego from the IDENTITY service. The service
603 is still in an early stage, so its protocol (currently version 0.1)
604 will likely adapt or change in future releases to some degree.
605 <br />
606 In terms of usability, users should be aware that there are still
607 <b>
608 a number of known open issues
609 </b>
610 in particular with respect to ease
611 of use, but also some critical privacy issues especially for mobile users.
612 Also, the nascent network is tiny and thus unlikely to
613 provide good anonymity or extensive amounts of interesting information.
614 As a result, the 0.15.0 release is still
615 <b>
616 only suitable for early adopters
617 with some reasonable pain tolerance
618 </b>
619 .

843 <link>https://guix.gnu.org/blog/2021/taming-the-stat-storm-with-a-loader-cache/</link>
844 <description> <p>It was one of these days where some of us on IRC were rehashing that old
845 problem—that application startup in Guix causes a
846 “<a href="https://linux.die.net/man/2/stat"><code>stat</code></a> storm”—and lamenting the
847 lack of a solution when suddenly, Ricardo
848 <a href="https://logs.guix.gnu.org/guix/2020-11-24.log#183934">proposes</a> what,
849 in hindsight, looks like an obvious solution: “maybe we could use a
850 per-application ld cache?”. A moment where collective thinking exceeds
851 the sum of our individual thoughts. The result is one of the many
852 features that made it in the <code>core-updates</code> branch, slated to be merged
853 in the coming weeks, one that reduces application startup time.</p><h1>ELF files and their dependencies</h1><p>Before going into detail, let’s look at what those “<code>stat</code> storms” look
854 like and where they come from. Loading an
855 <a href="https://en.wikipedia.org/wiki/Executable_and_Linkable_Format">ELF</a>
856 executable involves loading the shared libraries (the <code>.so</code> files, for
857 “shared objects”) it depends on, recursively. This is the job of the
858 <em>loader</em> (or <em>dynamic linker</em>), <code>ld.so</code>, which is part of the GNU C
859 Library (glibc) package. What shared libraries an executable like that
860 of Emacs depends on? The <code>ldd</code> command answers that question:</p><pre><code>$ ldd $(type -P .emacs-27.2-real)
861 linux-vdso.so.1 (0x00007fff565bb000)

869 $ ldd $(type -P .emacs-27.2-real) | wc -l
870 89</code></pre><p>(If you’re wondering why we’re looking at <code>.emacs-27.2-real</code> rather than
871 <code>emacs-27.2</code>, it’s because in Guix the latter is a tiny shell wrapper
872 around the former.)</p><p>To load a graphical program like Emacs, the loader needs to load more
873 than 80 shared libraries! Each is in its own <code>/gnu/store</code> sub-directory
874 in Guix, one directory per package.</p><p>But how does <code>ld.so</code> know where to find these libraries in the first
875 place? In Guix, during the link phase that produces an ELF file
876 (executable or shared library), we tell the
877 <a href="https://en.wikipedia.org/wiki/Linker_%28computing%29">linker</a> to
878 populate the <code>RUNPATH</code> entry of the ELF file with the list of
879 directories where its dependencies may be found. This is done by
880 passing
881 <a href="https://sourceware.org/binutils/docs/ld/Options.html#index-_002drpath_003ddir"><code>-rpath</code></a>
882 options to the linker, which Guix’s <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/ld-wrapper.in">“linker
883 wrapper”</a>
884 takes care of. The <code>RUNPATH</code> is the <em>run-time library search path</em>:
885 it’s a colon-separated list of directories where <code>ld.so</code> will look for
886 shared libraries when it loads an ELF file. We can look at the
887 <code>RUNPATH</code> of our Emacs executable like this:</p><pre><code>$ objdump -x $(type -P .emacs-27.2-real) | grep RUNPATH
888 RUNPATH /gnu/store/fa6wj5bxkj5ll1d7292a70knmyl7a0cr-glibc-2.31/lib:/gnu/store/01b4w3m6mp55y531kyi1g8shh722kwqm-gcc-7.5.0-lib/lib:/gnu/store/l1wwr5c34593gqxvp34qbwdkaf7xhdbd-libtiff-4.2.0/lib:/gnu/store/5khkwz9g6vza1n4z8xlmdrwhazz7m8wp-libjpeg-turbo-2.0.5/lib:[…]</code></pre><p>This <code>RUNPATH</code> has 39 entries, which roughly corresponds to the number
889 of direct dependencies of the executable—dependencies are listed as
890 <code>NEEDED</code> entries in the ELF file:</p><pre><code>$ objdump -x $(type -P .emacs-27.2-real) | grep NEED | head
891 NEEDED libtiff.so.5
892 NEEDED libjpeg.so.62
893 NEEDED libpng16.so.16
894 NEEDED libz.so.1
895 NEEDED libgif.so.7
896 NEEDED libXpm.so.4
897 NEEDED libgtk-3.so.0
898 NEEDED libgdk-3.so.0
899 NEEDED libpangocairo-1.0.so.0
900 NEEDED libpango-1.0.so.0
901 $ objdump -x $(type -P .emacs-27.2-real) | grep NEED | wc -l
902 52</code></pre><p>(Some of these <code>.so</code> files live in the same directory, which is why
903 there are more <code>NEEDED</code> entries than directories in the <code>RUNPATH</code>.)</p><p>A system such as Debian that follows the <a href="https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard">file system hierarchy
904 standard</a>
905 (FHS), where all libraries are in <code>/lib</code> or <code>/usr/lib</code>, does not have to
906 bother with <code>RUNPATH</code>: all <code>.so</code> files are known to be found in one of
907 these two “standard” locations. Anyway, let’s get back to our initial
908 topic: the “<code>stat</code> storm”.</p><h1>Walking search paths</h1><p>As you can guess, when we run Emacs, the loader first needs to locate
909 and load the 80+ shared libraries it depends on. That’s where things
910 get pretty inefficient: the loader will search each <code>.so</code> file Emacs
911 depends on in one of the 39 directories listed in its <code>RUNPATH</code>.
912 Likewise, when it finally finds <code>libgtk-3.so</code>, it’ll look for its
913 dependencies in each of the directories in its <code>RUNPATH</code>. We can see
914 that at play by tracing system calls with the
915 <a href="https://strace.io/"><code>strace</code></a> command:</p><pre><code>$ strace -c emacs --version

961 […]</code></pre><p>Above is the sequence where we see <code>ld.so</code> look for <code>libpng16.so.16</code>,
962 searching in locations where we <em>know</em> it’s not going to find it. A bit
963 ridiculous. How does this affect performance? The impact is small in
964 the most favorable case—on a hot cache, with fast solid state device
965 (SSD) storage. But it likely has a visible effect in other cases—on a
966 cold cache, with a slower spinning hard disk drive (HDD), on a network
967 file system (NFS).</p><h1>Enter the per-package loader cache</h1><p>The idea that Ricardo submitted, using a loader cache, makes a lot of
968 sense: we know from the start that <code>libpng.so</code> may only be found in
969 <code>/gnu/store/…-libpng-1.6.37</code>, no need to look elsewhere. In fact, it’s
970 not new: glibc has had such a cache “forever”; it’s the
971 <code>/etc/ld.so.cache</code> file you can see on FHS distros and which is
972 typically created by running
973 <a href="https://linux.die.net/man/8/ldconfig"><code>ldconfig</code></a> when a package has
974 been installed. Roughly, the cache maps library <code>SONAME</code>s, such as
975 <code>libpng16.so.16</code>, to their file name on disk, say
976 <code>/usr/lib/libpng16.so.16</code>.</p><p>The problem is that this cache is inherently system-wide: it assumes
977 that there is only <em>one</em> <code>libpng16.so</code> on the system; any binary that
978 depends on <code>libpng16.so</code> will load it from its one and only location.
979 This models perfectly matches the FHS, but it’s at odds with the
980 flexibility offered by Guix, where several variants or versions of the
981 library can coexist on the system, used by different applications.
982 That’s the reason why Guix and other non-FHS distros such as NixOS or
983 GoboLinux typically <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/base.scm?id=a92dfbce30777de6ca05031e275410cf9f56c84c#n716">turn
984 off</a>
985 that feature altogether… and pay the cost of those <code>stat</code> storms.</p><p>The insight we gained on that Tuesday evening IRC conversation is that
986 we could <em>adapt</em> glibc’s loader cache to our setting: instead of a
987 system-wide cache, we’d have a <em>per-application loader cache</em>. As one
988 of the last package <a href="https://guix.gnu.org/manual/en/html_node/Build-Phases.html">build
989 phases</a>,
990 we’d run <code>ldconfig</code> to create <code>etc/ld.so.cache</code> within that package’s
991 <code>/gnu/store</code> sub-directory. We then need to modify the loader so it
992 would look for <code>${ORIGIN}/../etc/ld.so.cache</code> instead of
993 <code>/etc/ld.so.cache</code>, where <code>${ORIGIN}</code> is the location of the ELF file
994 being loaded. A discussion of these changes is <a href="https://issues.guix.gnu.org/44899">in the issue
995 tracker</a>; you can see <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/patches/glibc-dl-cache.patch?h=core-updates&amp;id=0236013cd0fc86ff4a042885c735e3f36a7f5c25">the glibc
996 patch</a>
997 and the new <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/guix/build/gnu-build-system.scm?h=core-updates&amp;id=0236013cd0fc86ff4a042885c735e3f36a7f5c25#n735"><code>make-dynamic-linker-cache</code> build
998 phase</a>.
999 In short, the <code>make-dynamic-linker-cache</code> phase computes the set of
1000 direct and indirect dependencies of an ELF file using the
1001 <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/guix/build/gremlin.scm?id=0236013cd0fc86ff4a042885c735e3f36a7f5c25#n265"><code>file-needed/recursive</code></a>
1002 procedure and derives from that the library search path, creates a
1003 temporary <code>ld.so.conf</code> file containing this search path for use by
1004 <code>ldconfig</code>, and finally runs <code>ldconfig</code> to actually build the cache.</p><p>How does this play out in practice? Let’s try an <code>emacs</code> build that
1005 uses this new loader cache:</p><pre><code>$ strace -c /gnu/store/ijgcbf790z4x2mkjx2ha893hhmqrj29j-emacs-27.2/bin/emacs --version

1026 us know</a> how this impacts load time for
1027 you.</p><h1>Flexibility without <code>stat</code> storms</h1><p>With <a href="https://www.gnu.org/software/stow">GNU Stow</a> in the 1990s, and
1028 then Nix, Guix, and other distros, the benefits of flexible file layouts
1029 rather than the rigid Unix-inherited FHS have been demonstrated—nowadays
1030 I see it as an antidote to opaque and bloated application bundles à la
1031 Docker. Luckily, few of our system tools have FHS assumptions baked in,
1032 probably in large part thanks to GNU’s insistence on a <a href="https://www.gnu.org/prep/standards/html_node/Directory-Variables.html">rigorous
1033 installation directory
1034 categorization</a>
1035 in the early days rather than hard-coded directory names. The loader
1036 cache is one of the few exceptions. Adapting it to a non-FHS context is
1037 fruitful for Guix and for the other distros and packaging tools in a
1038 similar situation; perhaps it could become an option in glibc proper?</p><p>This is not the end of <code>stat</code> storms, though. Interpreters and language
1039 run-time systems rely on search paths—<code>GUILE_LOAD_PATH</code> for Guile,
1040 <code>PYTHONPATH</code> for Python, <code>OCAMLPATH</code> for OCaml, etc.—and are equally
1041 prone to stormy application startups. Unlike ELF, they do not have a
1042 mechanism akin to <code>RUNPATH</code>, let alone a run-time search path cache. We
1043 have yet to find ways to address these.</p><h4>About GNU Guix</h4><p><a href="https://guix.gnu.org">GNU Guix</a> is a transactional package manager and

1068 <p>The GNU C Library version 2.34 is now available.
1069 <br />
1070 </p>
1071 <p>The GNU C Library is used as <strong>the</strong> C library in the GNU system and
1072 <br />
1073 in GNU/Linux systems, as well as many other systems that use Linux
1074 <br />
1075 as the kernel.
1076 <br />
1077 </p>
1078 <p>The GNU C Library is primarily designed to be a portable
1079 <br />
1080 and high performance C library. It follows all relevant
1081 <br />
1082 standards including ISO C11 and POSIX.1-2017. It is also
1083 <br />
1084 internationalized and has one of the most complete
1085 <br />
1086 internationalization interfaces known.
1087 <br />

1102 <p>NEWS for version 2.34
1103 <br />
1104 =====================
1105 <br />
1106 </p>
1107 <p>Major new features:
1108 <br />
1109 </p>
1110 <ul>
1111 <li>In order to support smoother in-place-upgrades and to simplify
1112 </li>
1113 </ul><p> the implementation of the runtime all functionality formerly
1114 <br />
1115 implemented in the libraries libpthread, libdl, libutil, libanl has
1116 <br />
1117 been integrated into libc. New applications do not need to link with
1118 <br />
1119 -lpthread, -ldl, -lutil, -lanl anymore. For backwards compatibility,
1120 <br />
1121 empty static archives libpthread.a, libdl.a, libutil.a, libanl.a are
1122 <br />
1123 provided, so that the linker options keep working. Applications which
1124 <br />
1125 have been linked against glibc 2.33 or earlier continue to load the
1126 <br />
1127 corresponding shared objects (which are now empty). The integration
1128 <br />
1129 of those libraries into libc means that additional symbols become
1130 <br />
1131 available by default. This can cause applications that contain weak
1132 <br />
1133 references to take unexpected code paths that would only have been
1134 <br />
1135 used in previous glibc versions when e.g. preloading libpthread.so.0,
1136 <br />
1137 potentially exposing application bugs.
1138 <br />
1139 </p>
1140 <ul>
1141 <li>When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined,
1142 </li>
1143 </ul><p> PTHREAD_STACK_MIN is no longer constant and is redefined to
1144 <br />
1145 sysconf(_SC_THREAD_STACK_MIN). This supports dynamic sized register
1146 <br />
1147 sets for modern architectural features like Arm SVE.
1148 <br />
1149 </p>
1150 <ul>
1151 <li>Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ. When _DYNAMIC_STACK_SIZE_SOURCE
1152 </li>
1153 </ul><p> or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are no longer
1154 <br />
1155 constant on Linux. MINSIGSTKSZ is redefined to sysconf(_SC_MINSIGSTKSZ)
1156 <br />
1157 and SIGSTKSZ is redefined to sysconf (_SC_SIGSTKSZ). This supports
1158 <br />
1159 dynamic sized register sets for modern architectural features like
1160 <br />
1161 Arm SVE.
1162 <br />
1163 </p>
1164 <ul>
1165 <li>The dynamic linker implements the --list-diagnostics option, printing
1166 </li>
1167 </ul><p> a dump of information related to IFUNC resolver operation and
1168 <br />
1169 glibc-hwcaps subdirectory selection.
1170 <br />
1171 </p>
1172 <ul>
1173 <li>On Linux, the function execveat has been added. It operates similar to
1174 </li>
1175 </ul><p> execve and it is is already used to implement fexecve without requiring
1176 <br />
1177 /proc to be mounted. However, different than fexecve, if the syscall is not
1178 <br />
1179 supported by the kernel an error is returned instead of trying a fallback.
1180 <br />
1181 </p>
1182 <ul>
1183 <li>The ISO C2X function timespec_getres has been added.
1184 </li>
1185 </ul>
1186 <ul>
1187 <li>The feature test macro <em>_STDC_WANT_IEC_60559_EXT_</em>, from draft ISO
1188 </li>
1189 </ul><p> C2X, is supported to enable declarations of functions defined in Annex F
1190 <br />
1191 of C2X. Those declarations are also enabled when
1192 <br />
1193 <em>_STDC_WANT_IEC_60559_BFP_EXT_</em>, as specified in TS 18661-1, is
1194 <br />
1195 defined, and when _GNU_SOURCE is defined.
1196 <br />
1197 </p>
1198 <ul>
1199 <li>On powerpc64*, glibc can now be compiled without scv support using the
1200 </li>
1201 </ul><p> --disable-scv configure option.
1202 <br />
1203 </p>
1204 <ul>
1205 <li>Add support for 64-bit time_t on configurations like x86 where time_t
1206 </li>
1207 </ul><p> is traditionally 32-bit. Although time_t still defaults to 32-bit on
1208 <br />
1209 these configurations, this default may change in future versions.
1210 <br />
1211 This is enabled with the _TIME_BITS preprocessor macro set to 64 and is
1212 <br />
1213 only supported when LFS (_FILE_OFFSET_BITS=64) is also enabled. It is
1214 <br />
1215 only enabled for Linux and the full support requires a minimum kernel
1216 <br />
1217 version of 5.1.
1218 <br />
1219 </p>
1220 <ul>
1221 <li>The main gconv-modules file in glibc now contains only a small set of
1222 </li>
1223 </ul><p> essential converter modules and the rest have been moved into a supplementary
1224 <br />
1225 configuration file gconv-modules-extra.conf in the gconv-modules.d directory
1226 <br />
1227 in the same GCONV_PATH. Similarly, external converter modules directories
1228 <br />
1229 may have supplementary configuration files in a gconv-modules.d directory
1230 <br />
1231 with names ending with .conf to logically classify the converter modules in
1232 <br />
1233 that directory.
1234 <br />
1235 </p>
1236 <ul>
1237 <li>On Linux, a new tunable, glibc.pthread.stack_cache_size, can be used
1238 </li>
1239 </ul><p> to configure the size of the thread stack cache.
1240 <br />
1241 </p>
1242 <ul>
1243 <li>The function _Fork has been added as an async-signal-safe fork replacement
1244 </li>
1245 </ul><p> since Austin Group issue 62 droped the async-signal-safe requirement for
1246 <br />
1247 fork (and it will be included in the future POSIX standard). The new _Fork
1248 <br />
1249 function does not run any atfork function neither resets any internal state
1250 <br />
1251 or lock (such as the malloc one), and only sets up a minimal state required
1252 <br />
1253 to call async-signal-safe functions (such as raise or execve). This function
1254 <br />
1255 is currently a GNU extension.
1256 <br />
1257 </p>
1258 <ul>
1259 <li>On Linux, the close_range function has been added. It allows efficiently
1260 </li>
1261 </ul><p> closing a range of file descriptors on recent kernels (version 5.9).
1262 <br />
1263 </p>
1264 <ul>
1265 <li>The function closefrom has been added. It closes all file descriptors
1266 </li>
1267 </ul><p> greater than or equal to a given integer. This function is a GNU extension,
1268 <br />
1269 although it is also present in other systems.
1270 <br />
1271 </p>
1272 <ul>
1273 <li>The posix_spawn_file_actions_addclosefrom_np function has been added,
1274 </li>
1275 </ul><p> enabling posix_spawn and posix_spawnp to close all file descriptors greater
1276 <br />
1277 than or equal to a given integer. This function is a GNU extension,
1278 <br />
1279 although Solaris also provides a similar function.
1280 <br />
1281 </p>
1282 <p>Deprecated and removed features, and other changes affecting compatibility:
1283 <br />
1284 </p>
1285 <ul>
1286 <li>The function pthread_mutex_consistent_np has been deprecated; programs
1287 </li>
1288 </ul><p> should use the equivalent standard function pthread_mutex_consistent
1289 <br />
1290 instead.
1291 <br />
1292 </p>
1293 <ul>
1294 <li>The function pthread_mutexattr_getrobust_np has been deprecated;
1295 </li>
1296 </ul><p> programs should use the equivalent standard function
1297 <br />
1298 pthread_mutexattr_getrobust instead.
1299 <br />
1300 </p>
1301 <ul>
1302 <li>The function pthread_mutexattr_setrobust_np has been deprecated;
1303 </li>
1304 </ul><p> programs should use the equivalent standard function
1305 <br />
1306 pthread_mutexattr_setrobust instead.
1307 <br />
1308 </p>
1309 <ul>
1310 <li>The function pthread_yield has been deprecated; programs should use
1311 </li>
1312 </ul><p> the equivalent standard function sched_yield instead.
1313 <br />
1314 </p>
1315 <ul>
1316 <li>The function inet_neta declared in &lt;arpa/inet.h&gt; has been deprecated.
1317 </li>
1318 </ul>
1319 <ul>
1320 <li>Various rarely-used functions declared in &lt;resolv.h&gt; and
1321 </li>
1322 </ul><p> &lt;arpa/nameser.h&gt; have been deprecated. Applications are encouraged to
1323 <br />
1324 use dedicated DNS processing libraries if applicable. For &lt;resolv.h&gt;,
1325 <br />
1326 this affects the functions dn_count_labels, fp_nquery, fp_query,
1327 <br />
1328 fp_resstat, hostalias, loc_aton, loc_ntoa, p_cdname, p_cdnname,
1329 <br />
1330 p_class, p_fqname, p_fqnname, p_option, p_query, p_rcode, p_time,
1331 <br />
1332 p_type, putlong, putshort, res_hostalias, res_isourserver,
1333 <br />
1334 res_nameinquery, res_queriesmatch, res_randomid, sym_ntop, sym_ntos,
1335 <br />
1336 sym_ston. For &lt;arpa/nameser.h&gt;, the functions ns_datetosecs,
1337 <br />
1338 ns_format_ttl, ns_makecanon, ns_parse_ttl, ns_samedomain, ns_samename,
1339 <br />
1340 ns_sprintrr, ns_sprintrrf, ns_subdomain have been deprecated.
1341 <br />
1342 </p>
1343 <ul>
1344 <li>Various symbols previously defined in libresolv have been moved to libc
1345 </li>
1346 </ul><p> in order to prepare for libresolv moving entirely into libc (see earlier
1347 <br />
1348 entry for merging libraries into libc). The symbols __dn_comp,
1349 <br />
1350 __dn_expand, __dn_skipname, __res_dnok, __res_hnok, __res_mailok,
1351 <br />
1352 __res_mkquery, __res_nmkquery, __res_nquery, __res_nquerydomain,
1353 <br />
1354 __res_nsearch, __res_nsend, __res_ownok, __res_query, __res_querydomain,
1355 <br />
1356 __res_search, __res_send formerly in libresolv have been renamed and no
1357 <br />
1358 longer have a __ prefix. They are now available in libc.
1359 <br />
1360 </p>
1361 <ul>
1362 <li>The pthread cancellation handler is now installed with SA_RESTART and
1363 </li>
1364 </ul><p> pthread_cancel will always send the internal SIGCANCEL on a cancellation
1365 <br />
1366 request. It should not be visible to applications since the cancellation
1367 <br />
1368 handler should either act upon cancellation (if asynchronous cancellation
1369 <br />
1370 is enabled) or ignore the cancellation internal signal. However there are
1371 <br />
1372 buggy kernel interfaces (for instance some CIFS versions) that could still
1373 <br />
1374 see a spurious EINTR error when cancellation interrupts a blocking syscall.
1375 <br />
1376 </p>
1377 <ul>
1378 <li>Previously, glibc installed its various shared objects under versioned
1379 </li>
1380 </ul><p> file names such as libc-2.33.so. The ABI sonames (e.g., libc.so.6)
1381 <br />
1382 were provided as symbolic links. Starting with glibc 2.34, the shared
1383 <br />
1384 objects are installed under their ABI sonames directly, without
1385 <br />
1386 symbolic links. This increases compatibility with distribution
1387 <br />
1388 package managers that delete removed files late during the package
1389 <br />
1390 upgrade or downgrade process.
1391 <br />
1392 </p>
1393 <ul>
1394 <li>The symbols mallwatch and tr_break are now deprecated and no longer used in
1395 </li>
1396 </ul><p> mtrace. Similar functionality can be achieved by using conditional
1397 <br />
1398 breakpoints within mtrace functions from within gdb.
1399 <br />
1400 </p>
1401 <ul>
1402 <li>The __morecore and __after_morecore_hook malloc hooks and the default
1403 </li>
1404 </ul><p> implementation __default_morecore have been removed from the API. Existing
1405 <br />
1406 applications will continue to link against these symbols but the interfaces
1407 <br />
1408 no longer have any effect on malloc.
1409 <br />
1410 </p>
1411 <ul>
1412 <li>Debugging features in malloc such as the MALLOC_CHECK_ environment variable
1413 </li>
1414 </ul><p> (or the glibc.malloc.check tunable), mtrace() and mcheck() have now been
1415 <br />
1416 disabled by default in the main C library. Users looking to use these
1417 <br />
1418 features now need to preload a new debugging DSO libc_malloc_debug.so to get
1419 <br />
1420 this functionality back.
1421 <br />
1422 </p>
1423 <ul>
1424 <li>The deprecated functions malloc_get_state and malloc_set_state have been
1425 </li>
1426 </ul><p> moved from the core C library into libc_malloc_debug.so. Legacy applications
1427 <br />
1428 that still use these functions will now need to preload libc_malloc_debug.so
1429 <br />
1430 in their environment using the LD_PRELOAD environment variable.
1431 <br />
1432 </p>
1433 <ul>
1434 <li>The deprecated memory allocation hooks __malloc_hook, __realloc_hook,
1435 </li>
1436 </ul><p> __memalign_hook and __free_hook are now removed from the API. Compatibility
1437 <br />
1438 symbols are present to support legacy programs but new applications can no
1439 <br />
1440 longer link to these symbols. These hooks no longer have any effect on glibc
1441 <br />
1442 functionality. The malloc debugging DSO libc_malloc_debug.so currently
1443 <br />
1444 supports hooks and can be preloaded to get this functionality back for older
1445 <br />
1446 programs. However this is a transitional measure and may be removed in a
1447 <br />
1448 future release of the GNU C Library. Users may port away from these hooks by
1449 <br />
1450 writing and preloading their own malloc interposition library.
1451 <br />
1452 </p>
1453 <p>Changes to build and runtime requirements:
1454 <br />
1455 </p>
1456 <ul>
1457 <li>On Linux, the shm_open, sem_open, and related functions now expect the
1458 </li>
1459 </ul><p> file shared memory file system to be mounted at /dev/shm. These functions
1460 <br />
1461 no longer search among the system's mount points for a suitable
1462 <br />
1463 replacement if /dev/shm is not available.
1464 <br />
1465 </p>
1466 <p>Security related changes:
1467 <br />
1468 </p>
1469 <p> CVE-2021-27645: The nameserver caching daemon (nscd), when processing
1470 <br />
1471 a request for netgroup lookup, may crash due to a double-free,
1472 <br />
1473 potentially resulting in degraded service or Denial of Service on the
1474 <br />
1475 local system. Reported by Chris Schanzle.
1476 <br />
1477 </p>
1478 <p> CVE-2021-33574: The mq_notify function has a potential use-after-free
1479 <br />
1480 issue when using a notification type of SIGEV_THREAD and a thread
1481 <br />
1482 attribute with a non-default affinity mask.
1483 <br />
1484 </p>
1485 <p> CVE-2021-35942: The wordexp function may overflow the positional
1486 <br />
1487 parameter number when processing the expansion resulting in a crash.
1488 <br />
1489 Reported by Philippe Antoine.
1490 <br />

1933 <description> <blockquote class="verbatim"><p> This is to announce diffutils-3.8, a stable release.<br />
1934 <br />
1935 There have been 47 commits by 5 people in the 2.6 years since 3.7.<br />
1936 <br />
1937 See the NEWS below for a brief summary.<br />
1938 <br />
1939 Thanks to everyone who has contributed!<br />
1940 The following people contributed changes to this release:<br />
1941 <br />
1942 Bruno Haible (2)<br />
1943 Dave Odell (1)<br />
1944 Jim Meyering (23)<br />
1945 KO Myung-Hun (1)<br />
1946 Paul Eggert (20)<br />
1947 <br />
1948 Jim [on behalf of the diffutils maintainers]<br />
1949 ==================================================================<br />
1950 <br />
1951 Here is the GNU diffutils home page:<br />
1952 http://gnu.org/s/diffutils/<br />
1953 <br />
1954 For a summary of changes and contributors, see:<br />
1955 http://git.sv.gnu.org/gitweb/?p=diffutils.git;a=shortlog;h=v3.8<br />
1956 or run this command from a git-cloned diffutils directory:<br />
1957 git shortlog v3.7..v3.8<br />
1958 <br />
1959 To summarize the 2453 gnulib-related changes, run these commands<br />
1960 from a git-cloned diffutils directory:<br />
1961 git checkout v3.8<br />
1962 git submodule summary v3.7<br />
1963 <br />
1964 Here are the compressed sources and a GPG detached signature[*]:<br />
1965 https://ftp.gnu.org/gnu/diffutils/diffutils-3.8.tar.xz<br />
1966 https://ftp.gnu.org/gnu/diffutils/diffutils-3.8.tar.xz.sig<br />
1967 <br />
1968 Use a mirror for higher download bandwidth:<br />
1969 https://ftpmirror.gnu.org/diffutils/diffutils-3.8.tar.xz<br />
1970 https://ftpmirror.gnu.org/diffutils/diffutils-3.8.tar.xz.sig<br />
1971 <br />
1972 [*] Use a .sig file to verify that the corresponding file (without the<br />
1973 .sig suffix) is intact. First, be sure to download both the .sig file<br />
1974 and the corresponding tarball. Then, run a command like this:<br />
1975 <br />
1976 gpg --verify diffutils-3.8.tar.xz.sig<br />
1977 <br />
1978 If that command fails because you don't have the required public key,<br />
1979 then run this command to import it:<br />
1980 <br />
1981 gpg --keyserver keys.gnupg.net --recv-keys 7FD9FCCB000BEEEE<br />
1982 <br />
1983 and rerun the 'gpg --verify' command.<br />
1984 <br />
1985 This release was bootstrapped with the following tools:<br />
1986 Autoconf 2.71<br />
1987 Automake 1.16d<br />
1988 Gnulib v0.1-4758-gb48905892<br />
1989 <br />
1990 NEWS<br />
1991 <br />
1992 * Noteworthy changes in release 3.8 (2021-08-01) [stable]<br />
1993 <br />
1994 ** Incompatible changes<br />
1995 <br />
1996 diff no longer treats a closed stdin as representing an absent file<br />
1997 in usage like 'diff --new-file - foo &lt;&amp;-'. This feature was rarely<br />
1998 if ever used and was not portable to POSIX platforms that reopen<br />
1999 stdin on exec, such as SELinux if the process underwent an AT_SECURE<br />
2000 transition, or HP-UX even if not setuid.<br />
2001 [bug#33965 introduced in 2.8]<br />
2002 <br />
2003 ** Bug fixes<br />
2004 <br />
2005 diff and related programs no longer get confused if stdin, stdout,<br />
2006 or stderr are closed. Previously, they sometimes opened files into<br />
2007 file descriptors 0, 1, or 2 and then mistakenly did I/O with them<br />
2008 that was intended for stdin, stdout, or stderr.<br />
2009 [bug#33965 present since "the beginning"]<br />
2010 <br />
2011 cmp, diff and sdiff no longer treat negative command-line<br />
2012 option-arguments as if they were large positive numbers.<br />
2013 [bug#35256 introduced in 2.8]<br />

2080 <title>parallel @ Savannah: GNU Parallel 20210722 ('Blue Unity') released</title>
2081 <guid>http://savannah.gnu.org/forum/forum.php?forum_id=10027</guid>

2083 <description> <p>GNU Parallel 20210722 ('Blue Unity') has been released. It is available for download at: lbry://@GnuParallel:4
2084 <br />
2085 </p>
2086 <p>Please help spreading GNU Parallel by making a testimonial video like Juan Sierra Pons: <a href="http://www.elsotanillo.net/wp-content/uploads/GnuParallel_JuanSierraPons.mp4">http://www.elsotanillo.net/wp-content/uploads/GnuParallel_JuanSierraPons.mp4</a>
2087 <br />
2088 </p>
2089 <p>It does not have to be as detailed as Juan's. It is perfectly fine if you just say your name, and what field you are using GNU Parallel for.
2090 <br />
2091 </p>
2092 <p>Quote of the month:
2093 <br />
2094 </p>
2095 <p> We use gnu parallel now - and happier for it.

2137 <h2>About GNU Parallel</h2>
2138
2139 <p>GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel.
2140 <br />
2141 </p>
2142 <p>If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops.
2143 <br />
2144 </p>
2145 <p>GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs.
2146 <br />
2147 </p>
2148 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
2149 <br />
2150 </p>
2151 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
2152 <br />
2153 </p>
2154 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
2155 <br />
2156 </p>
2157 <p> find . -name '*.jpg' |
2158 <br />
2159 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
2160 <br />
2161 </p>
2162 <p>You can find more about GNU Parallel at: <a href="http://www.gnu.org/s/parallel/">http://www.gnu.org/s/parallel/</a>
2163 <br />
2164 </p>

2233 <h2>About GNU SQL</h2>
2234
2235 <p>GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries.
2236 <br />
2237 </p>
2238 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.
2239 <br />

2241 <p>When using GNU SQL for a publication please cite:

2248 <h2>About GNU Niceload</h2>
2249
2250 <p>GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.<br />

2276 <title>GNU Health: Back to the Future</title>

2279 <description> <p class="has-drop-cap">Leonardo da Vinci said “<em>simplicity is the ultimate sophistication</em>“, but it seems like the “modern” computing world never heard that quote, or ignore it. Today, a single application takes hundreds of megabytes, both of disk and RAM space. Slow, buggy, inefficient systems at every level. </p>
2280
2281
2282
2283 <p>Probably the best example on this cluttering mess comes from the mobile computing. Most phones are bloated with useless software that not only hinders the navigation experience, but pose a threat to your privacy. Yes, all this software is proprietary. Worst of it, you can not even uninstall it.</p>
2284
2285
2286
2287 <p>Fortunately, there is hope. Let me introduce <strong>SXMO, the Simple X on Mobile </strong>project. As the authors describe it, SXMO is a minimalist environment for Linux smartphones, such as the <strong>PinePhone</strong>. SXMO embraces simplicity, and simplicity is both elegant and efficient. </p>

2303 </div>
2304
2305
2306
2307 <p>SXMO uses a tiling window manager called <strong>dwm</strong> (Dynamic Window Manager), which allocates the different applications in the most efficient way. The dwm project is available as a single binary file, which source is intended not to exceed 2000 lines of code. That is amazing.</p>
2308
2309
2310
2311 <p>Simplicity is robust, and that again applies to SXMO. All the necessary components expected on a mobile phone (making and receiving calls, browsing the Internet, SMS messaging,..) just work. Moreover, SMXO comes with a scripting system that allow us to write solutions to our needs. For instance, the screenshots you see were taken with a script of 3 lines of code. Just place the little program under your “<em>userscripts</em>” directory, and <em>voilà </em>!, you’re ready to make screenshots from your PinePhone!</p>

2338
2339
2340
2341 <p></p>
2342
2343
2344
2345 <p>I’m using SXMO on my PinePhone as a daily driver, and I just love it. Thanks to simple distributions such as Archlinux, Parabola or PostmarketOS, and simple Desktop / window managers as DWM, a am finally enjoying Libre mobile computing.</p>
2346
2347
2348
2349 <p>I feel projects like this take us back to the roots, to the beautiful world of simplicity, yet delivering the latest technology and showing us the path o the future.</p>

2456 <description> <p>Starting with <code>libxcrypt</code> 4.4.21, weak password hashes (such as <em>MD5</em> and <em>SHA1</em>) are no longer accepted for new passwords. Users that still have their passwords stored with a weak hash will be asked to update their password on their next login.</p>
2457 <p>If the login just fails (for example from display manager) switch to a virtual terminal (<em>Ctrl-Alt-F2</em>) and log in there once.</p> </description>

2504 <title>Christopher Allan Webber: Hello, I'm Chris Lemmer-Webber, and I'm nonbinary trans-femme</title>
2505 <guid>tag:dustycloud.org,2021-06-28:/blog/nonbinary-trans-femme/</guid>
2506 <link>http://dustycloud.org/blog/nonbinary-trans-femme/</link>
2507 <description> <p><img alt="A picture of Chris and Morgan together" src="https://dustycloud.org/gfx/goodies/chris-and-morgan-2021-06-27.jpg" /></p>
2508 <p>I recently came out as nonbinary trans-femme.
2509 That's a picture of me on the left, with my spouse Morgan Lemmer-Webber
2510 on the right.</p>
2511 <p>In a sense, not much has changed, and so much has changed.
2512 I've dropped the "-topher" from my name, and given the common tendency
2513 to apply gender to pronouns in English, please either use nonbinary
2514 pronouns or feminine pronouns to apply to me.
2515 Other changes are happening as I wander through this space, from
2516 appearance to other things.
2517 (Probably the biggest change is finally achieving something resembling
2518 self-acceptance, however.)</p>
2519 <p>If you want to know more,
2520 <a href="https://fossandcrafts.org/episodes/30-gender-sexuality-personal-perspective.html">Morgan and I did a podcast episode</a>
2521 which explains more from my present standing, and also explains Morgan's
2522 experiences with being demisexual, which not many people know about!
2523 (Morgan has been incredible through this whole process, by the way.)</p>
2524 <p>But things may change further.
2525 Maybe a year from now those changes may be even more drastic, or maybe
2526 not.
2527 We'll see.
2528 I am wandering, and I don't know where I will land, but it won't be
2529 back to where I was.</p>
2530 <p>At any rate, I've spent much of my life not being able to stand myself
2531 for how I look and feel.
2532 For most of my life, I have not been able to look at myself in a mirror
2533 for more than a second or two due to the revulsion I felt at the person
2534 I saw staring back at me.
2535 The last few weeks have been a shift change for me in that regard...
2536 it's a very new experience to feel so happy with myself.</p>
2537 <p>I'm only at the beginning of this journey.
2538 I'd appreciate your support... people have been incredibly kind to me
2539 by and large so far but like everyone who goes through a process like this,
2540 it's very hard in those experiences where people aren't.
2541 Thank you to everyone who has been there for me so far.</p> </description>

2546 <title>health @ Savannah: Welcome to MyGNUHealth, the GNU Health Libre Personal Health Record</title>
2547 <guid>http://savannah.gnu.org/forum/forum.php?forum_id=10015</guid>
2548 <link>http://savannah.gnu.org/forum/forum.php?forum_id=10015</link>
2549 <description> <p>Original article including MyGNUHealth pictures is at (<a href="https://meanmicio.org/2021/06/24/welcome-to-mygnuhealth-the-libre-personal-health-record/">https://meanmicio.org/2021/06/24/welcome-to-mygnuhealth-the-libre-personal-health-record/</a>)
2550 <br />
2551 </p>
2552 <p>---
2553 <br />
2554 </p>
2555
2556 <p><strong>MyGNUHealth</strong> 1.0 us out! The GNU Health Libre Personal Health Record is now ready for prime time!
2557 <br />
2558 </p>
2559 <p>This is great news. Great news because citizens around the world have now access to a Free/Libre application, focused on privacy, that puts them in control of their health.
2560 <br />
2561 </p>
2562 <p>Health is personal, so is the health data. It’s been years since I got the idea of expanding the GNU Health ecosystem, not only to the health professionals and institutions, but making it personal, accessible to individuals. Now is a reality!
2563 <br />
2564 </p>
2565 <p>Throughout these years, the mobile health (mHealth) has been governed by private companies that benefit from your health data. Private companies, private insurances, proprietary operating systems, proprietary health applications. Big business, no privacy.
2566 <br />
2567 </p>
2568 <p>The GNU Health ecosystem exists because of Free software. Thanks to communities such as GNU and KDE, we can have fully operational operating systems, desktop environments, databases and programming languages that allow us to use and write free software. GNU Health is one example.
2569 <br />
2570 </p>
2571 <p>The Libre Software movement fights for the advancement of our societies, by providing universality in computing. In the case of GNU Health, that freedom and equity in computing is applied into the healthcare and social medicine domains. Health is a non-negotiable human right, so it must be health informatics.
2572 <br />
2573 </p>
2574 <h3>What is MyGNUHealth?</h3>
2575
2576 <p>MyGNUHealth (MyGH)is a Health Personal Record application focused in <strong>privacy</strong>, that can be used in desktops and mobile devices.
2577 <br />
2578 </p>
2579 <p>MyGH embraces the main health domains (*bio-psycho-social*). All the components in the GNU Health ecosystem combine social medicine and primary care with the latest on bioinformatics and precision medicine. The complex interactions between these health domains play a key role in the state of health and disease of an individual, family and society.
2580 <br />
2581 </p>
2582 <p>MyGH has the functionality of a health and activity tracker, and that of a health diary / record. It records and tracks the main anthropometric and physiological measures, such as weight, blood pressure, blood sugar level or oxygen saturation. It keeps track of your lifestyle, nutrition, physical activity, and sleep, with numerous charts to visualize the trends.
2583 <br />
2584 </p>
2585 <p>MyGNUHealth is also a diary, that records all relevant information from the medical and social domain and their context. In the medical domain, you can record your encounters, immunizations, hospitalizations, lab tests,genetic and family history, among others. In the genetic context, MyGH provides a dataset of over 30000 natural variants / SNP from <strong>UniProt</strong> that are relevant in human. Entering the RefSNP will automatically provide the information about that particular variant and it clinical significance.
2586 <br />
2587 </p>
2588 <p>The Social domain, contains the key social determinants of health (Social Gradient, Early life development, Stress, Social exclusion, Working conditions, Education, Physical environment, Unemployment, Social Support, Addiction, Food, Transportation, Health services, Family functionality, Family violence, Bullying, War) , most of them from the World Health Organization social determinants of health.
2589 <br />
2590 </p>
2591 <p>A very important feature of MyGH is that it is GNU Health Federation. That is, if you want to share any of this data with your health professional in real-time, and they will be able to study it.
2592 <br />
2593 </p>
2594 <h3>The PinePhone and the revolution in mobile computing</h3>
2595
2596 <p>Of course, in a world of mobile phones and mobile computing, we need free/libre mobile applications. The problem I was facing until recently, that prevented me from writing MyGNUHealth, was the fact that there was no libre mobile environment. The mobile computing market has been dominated by Google and Apple, which both deliver proprietary operating systems, Android and iOS respectively.
2597 <br />
2598 </p>
2599 <p>The irruption of the <strong>Pine64</strong> community was the eye-opener and a game changer. A thriving community of talented people, determined to provide freedom in mobile computing. The Pine64 provides, among others, a smartphone (PinePhone), and a smartwatch (PineTime), and I have adopted both.
2600 <br />
2601 </p>
2602
2603 <p>I wrote an article some weeks ago (“Liberating our mobile computing”), where I mentioned why I have changed the Android phone to the PinePhone, and my watch to the PineTime.
2604 <br />
2605 </p>
2606 <p>Does the PinePhone have the best camera? Can we compare the PinePhone with Apple or Google products? It’s hard to compare a multi-billion dollar corporation with a fresh community oriented project. The business model, the technology components and the ethics behind are very different.
2607 <br />
2608 </p>
2609 <p>So, why making the move? I made the change because we, as a society, need to embrace a technology that is universal and that respects our freedom and privacy. A technology that if focus on the individual and not the corporation. That moves takes determination and commitment. There is a small price to pay, but freedom and privacy are priceless.
2610 <br />
2611 </p>
2612 <p>As a physician, I need to provide my patients the resources that use state-of-the-art technology, and, at the same time, guarantee the privacy of their sensitive medical information. Libre software and open standards are key in healthcare. When my patients choose free/libre software, they have full control. They also have the possibility to share it with me or with other health professionals, in real-time and with the highest levels of privacy.
2613 <br />
2614 </p>
2615 <p>We can only manage sensitive health data with technology that respects our privacy. In other words, we can not put our personal information in the hands of corporate interests. Choosing Libre Software and Hardware means much more than just technology. Libre Software means embracing solidarity and cooperation. It means sharing knowledge, code and time with others. It means embracing open science for the advancement of our societies, specially for those that need it most.
2616 <br />
2617 </p>
2618 <p>MyGNUHealth will be included by default in many operating systems and distributions, so you don’t have to worry about the technical details. Just use your health companion! If your operating system does not have MyGH in their repositories, please ask them to include it.
2619 <br />
2620 </p>
2621 <p>Governments, institutions, and health professional need affordable technology that respects their citizens freedom. We need you to be part of this eHealth revolution.
2622 <br />
2623 </p>
2624 <p>Happy and healthy hacking!

2847 <description> <p>This version of TeXmacs consolidates many developments that took place in the last decade. Most importantly, the interface is now based on Qt, which allowed us develop native versions for Linux, MacOS, and Windows. TeXmacs has evolved from a scientific text editor into a scientific office suite, with an integrated presentation mode, technical drawing editor, versioning tools, bibliography tool, etc. The typesetting quality has continued to improve with a better support of microtypography and a large variety of fonts. The converters for LaTeX and Html have also been further perfected and TeXmacs now comes with a native support for Pdf.<br />

2856 <description> <p>GNU Parallel 20210622 ('Protasevich') [stable] has been released. It is available for download at: lbry://@GnuParallel:4
2857 <br />
2858 </p>
2859 <p>No new functionality was introduced so this is a good candidate for a stable release.

2862 <p>Please help spreading GNU Parallel by making a testimonial video like Juan Sierra Pons: <a href="http://www.elsotanillo.net/wp-content/uploads/GnuParallel_JuanSierraPons.mp4">http://www.elsotanillo.net/wp-content/uploads/GnuParallel_JuanSierraPons.mp4</a>
2863 <br />
2864 </p>
2865 <p>It does not have to be as detailed as Juan's. It is perfectly fine if you just say your name, and what field you are using GNU Parallel for.

2919 <h2>About GNU Parallel</h2>
2920
2921 <p>GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel.
2922 <br />
2923 </p>
2924 <p>If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops.
2925 <br />
2926 </p>
2927 <p>GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs.
2928 <br />
2929 </p>
2930 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
2931 <br />
2932 </p>
2933 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
2934 <br />
2935 </p>
2936 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
2937 <br />
2938 </p>
2939 <p> find . -name '*.jpg' |
2940 <br />
2941 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
2942 <br />
2943 </p>

3015 <h2>About GNU SQL</h2>
3016
3017 <p>GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries.
3018 <br />
3019 </p>
3020 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.

3030 <h2>About GNU Niceload</h2>
3031
3032 <p>GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.<br />

3048 <title>GNU Guix: Substitutes now also available from bordeaux.guix.gnu.org</title>
3049 <guid>https://guix.gnu.org/blog/2021/substitutes-now-also-available-from-bordeauxguixgnuorg/</guid>
3050 <link>https://guix.gnu.org/blog/2021/substitutes-now-also-available-from-bordeauxguixgnuorg/</link>
3051 <description> <p>There have been a number of different project operated sources of
3052 substitutes, for the last couple of years the default source of
3053 substitutes has been <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> (with a few
3054 different URLs).</p><p>Now, in addition to <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a>,
3055 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> is a default substitute
3056 server.</p><p>Put that way, this development maybe doesn't sound particularly
3057 interesting. Why is a second substitute server useful? There's some
3058 thoughts on that exact question in the next section. If you're just
3059 interested in how to use (or how not to use) substitutes from
3060 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a>, then you can just skip
3061 ahead to the last section.</p><h1>Why a second source of substitutes?</h1><p>This change is an important milestone, following on from the work that
3062 started on the <a href="https://guix.gnu.org/en/blog/2021/building-derivations-how-complicated-can-it-be/">Guix Build Coordinator towards the start of
3063 2020</a>.</p><p>Back in 2020, the substitute availability from
3064 <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> was often an issue. There seemed
3065 to be a number of contributing factors, including some parts of the
3066 architecture. Without going too much in to the details of the issues,
3067 aspects of the design of the Guix Build Coordinator were specifically
3068 meant to avoid some of these issues.</p><p>While there were some very positive results from testing back in 2020,
3069 it's taken so long to bring the substitute availability benefits to
3070 general users of Guix that <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> has
3071 <a href="https://guix.gnu.org/en/blog/2021/cuirass-10-released/">changed and improved significantly in the meantime</a>.
3072 This means that any benefits in terms of substitute availability are
3073 less significant now.</p><p>One clearer benefit of just having two independent sources of
3074 substitutes is redundancy. While the availability of
3075 <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> has been very high (in my opinion),
3076 having a second independent substitute server should mean that if
3077 there's a future issue with users accessing either source of
3078 substitutes, the disruption should be reduced.</p><p>I'm also excited about the new possibilities offered by having a
3079 second substitute server, particularly one using the Guix Build
3080 Coordinator to manage the builds.</p><p>Substitutes for the Hurd is already something that's <a href="https://lists.gnu.org/archive/html/guix-devel/2021-03/msg00074.html">been
3081 prototyped</a>, so I'm hopeful that
3082 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> can start using
3083 <a href="https://guix.gnu.org/en/blog/2020/childhurds-and-substitutes/">childhurd VMs</a> to build things soon.</p><p>Looking a bit further forward, I think there's some benefits to be had
3084 in doing further work on how the nar and narinfo files used for
3085 substitutes are managed. There are some <a href="https://lists.gnu.org/archive/html/guix-devel/2021-02/msg00104.html">rough plans
3086 already</a> on how to address the
3087 retention of nars, and how to look at high performance mirrors.</p><p>Having two substitute servers is one step towards stronger trust
3088 policies for substitutes (<a href="https://lists.gnu.org/archive/html/guix-devel/2020-06/msg00179.html">as discussed on guix-devel</a>,
3089 where you would only use a substitute if both
3090 <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> and
3091 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> have built it exactly
3092 the same. This would help protect against the compromise of a single
3093 substitute server.</p><h1>Using substitutes from bordeaux.guix.gnu.org</h1><p>If you're using Guix System, and haven't altered the default
3094 substitute configuration, updating guix (via <code>guix pull</code>),
3095 reconfiguring using the updated guix, and then restarting the
3096 guix-daemon should enable substitutes from
3097 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a>.</p><p>If the ACL is being managed manually, you might need to add the public
3098 key for <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> manually as
3099 well.</p><p>When using Guix on a foreign distribution with the default substitute
3100 configuration, you'll need to run <code>guix pull</code> as root, then restart
3101 the guix-daemon. You'll then need to add the public key for
3102 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> to the ACL.</p><pre><code class="language-sh">guix archive --authorize &lt; /root/.config/guix/current/share/guix/bordeaux.guix.gnu.org.pub</code></pre><p>If you want to just use <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a>, or
3103 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> for that matter, you'll
3104 need to adjust the substitute urls configuration for the guix-daemon
3105 to just refer to the substitute servers you want to use.</p> </description>

3112 <link>http://savannah.gnu.org/forum/forum.php?forum_id=10011</link>
3113 <description> <p><a href="https://ftp.gnu.org/gnu/gdbm/gdbm-1.20.tar.gz">Version 1.20</a> is available for download.
3114 <br />
3115 </p>
3116 <p>Changes in this version:
3117 <br />
3118 </p>
3119 <h3>New bucket cache</h3>
3120
3121 <p>The bucket cache support has been rewritten from scratch. The new code provides for significant speed up of search operations.
3122 <br />
3123 </p>
3124 <h3>Change in the mmap prereading strategy</h3>
3125
3126 <p>Pre-reading of the memory mapper regions, introduced in version 1.19 can be advantageous only when doing intensive look-ups on a read-only
3127 <br />
3128 database. It degrades performance otherwise, especially if doing multiple inserts. Therefore, this version introduces a new flag
3129 <br />
3130 to gdbm_open: GDBM_PREREAD. When given, it enables pre-reading of memory mapped regions. (<a href="https://github.com/Perl/perl5/issues/18884">details</a>)<br />

3149 <description> <p>Last week, <a href="https://hpc.guix.info">we at Guix-HPC</a> published <a href="https://hpc.guix.info/events/2021/atelier-reproductibilit%C3%A9-environnements/">videos of
3150 a workshop on reproducible software

3152 we organized on-line. The videos are well worth watching—especially if
3153 you’re into reproducible research, and especially if you speak French or
3154 want to practice. This post, though, is more of a meta-post: it’s about
3155 how we processed these videos. “A workshop on reproducibility <em>ought to
3156 have</em> a reproducible video pipeline”, we thought. So this is what we

3158 participate in an on-line conference, or even to organize one. If so,
3159 chances are that you already know

3161 video conferencing suite initially designed for on-line teaching. In a
3162 nutshell, it allows participants to chat (audio, video, and keyboard),
3163 and speakers can share their screen or a PDF slide deck. Organizers can
3164 also record the session.</p><p>BBB then creates a link to recorded sessions with a custom JavaScript
3165 player that replays everything: typed chat, audio and video (webcams),
3166 shared screens, and slide decks. This BBB replay a bit too rough though
3167 and often not the thing you’d like to publish after the conference.
3168 Instead, you’d rather do a bit of editing: adjusting the start and end
3169 time of each talk, removing live chat from what’s displayed (which
3170 allows you to remove info that personally identifies participants,
3171 too!), and so forth. Turns out this kind of post-processing is a bit of
3172 work, primarily because BBB does “the right thing” of recording each
3173 stream separately, in the most appropriate form: webcam and screen
3174 shares are recorded as separate videos, chat is recorded as text with
3175 timings, slide decks is recorded as a bunch of PNGs plus timings, and
3176 then there’s a bunch of XML files with metadata putting it all together.</p><p>Anyway, with a bit of searching, we quickly found the handy
3177 <a href="https://github.com/plugorgau/bbb-render">bbb-render</a> tool, which can
3178 first
3179 <a href="https://github.com/plugorgau/bbb-render/blob/master/download.py">download</a>
3180 all these files and then
3181 <a href="https://github.com/plugorgau/bbb-render/blob/master/make-xges.py">assemble</a>
3182 them using the Python interface to the <a href="https://gstreamer.freedesktop.org/documentation/gst-editing-services/index.html">GStreamer Editing Services
3183 (GES)</a>.
3184 Good thing: we don’t have to figure out all these things; we “just” have
3185 to run these two scripts in an environment with the right dependencies.
3186 And guess what: we know of a great tool to control execution
3187 environments!</p><h1>A “deployment-aware Makefile”</h1><p>So we have a process that takes input files—those PNGs, videos, and XML
3188 files—and produces output files—WebM video files. As developers we
3189 immediately recognize a pattern and the timeless tool to deal with it:
3190 <a href="https://www.gnu.org/software/make"><code>make</code></a>. The web already seems to
3191 contain countless BBB post-processing makefiles (and shell scripts,
3192 too). We were going to contribute to this while we suddenly realized
3193 that we know of <em>another</em> great tool to express such processes: Guix!
3194 Bonus: while a makefile would address just the tip of the
3195 iceberg—running bbb-render—Guix can also take care of the tedious task
3196 of deploying the <em>right</em> environment to run bbb-render in.</p><p>What we did was to write some sort of a <em>deployment-aware makefile</em>.
3197 It’s still a relatively unconventional way to use Guix, but one that’s
3198 very convenient. We’re talking about videos, but really, you could use
3199 the same approach for any kind of processing graph where you’d be
3200 tempted to just use <code>make</code>.</p><p>The end result here is a <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/6977da4618814c790e767618da5cf9ec2cab0742/doc/atelier-reproductibilit%C3%A9/render-videos.scm">Guix
3201 file</a>
3202 that returns a <em>manifest</em>—a list of videos to “build”. You can build
3203 the videos with:</p><pre><code>guix build -m render-videos.scm</code></pre><p>Overall, the file defines a bunch of functions (<em>procedures</em> in
3204 traditional Scheme parlance), each of which takes input files and
3205 produces output files. More accurately, these functions returns objects
3206 that <em>describe</em> how to build their output from the input files—similar
3207 to how a <a href="https://www.gnu.org/software/make/manual/html_node/Rule-Introduction.html">makefile
3208 rule</a>
3209 describes how to build its target(s) from its prerequisite(s). (The
3210 reader familiar with functional programming may recognize a monad here,
3211 and indeed, those build descriptions can be thought of as monadic values
3212 in a hypothetical “Guix build” monad; technically though, they’re
3213 regular Scheme values.)</p><p>Let’s take a guided tour of this 300-line file.</p><h1>Rendering</h1><p>The <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/6977da4618814c790e767618da5cf9ec2cab0742/doc/atelier-reproductibilit%C3%A9/render-videos.scm#L23-75">first

3289 raw data, a start and end time, and produces a <code>video.ges</code> file. There
3290 are three key elements here:</p><ol><li><a href="https://guix.gnu.org/manual/en/html_node/G_002dExpressions.html#index-computed_002dfile"><code>computed-file</code></a>
3291 is a function to produce a file, <code>video.ges</code> in this case, by
3292 running the code you give it as its second argument—the <em>recipe</em>,
3293 in makefile terms.</li><li>The recipe passed to <code>computed-file</code> is a
3294 <a href="https://guix.gnu.org/manual/en/html_node/G_002dExpressions.html"><em>G-expression</em></a>
3295 (or “gexp”), introduced by this fancy <code>#~</code> (hash tilde) notation.
3296 G-expressions are a way to <em>stage</em> code, to mark it for eventual
3297 execution. Indeed, that code will only be executed if and when we
3298 run <code>guix build</code> (without <code>--dry-run</code>), and only if the result is
3299 not already in <a href="https://guix.gnu.org/manual/en/html_node/The-Store.html">the
3300 store</a>.</li><li>The gexp refers to <code>rendering-profile</code>, to <code>bbb-render</code>, to
3301 <code>bbb-data</code> and so on by <em>escaping</em> with the <code>#+</code> or <code>#$</code> syntax
3302 (they’re equivalent, unless doing cross-compilation). During
3303 build, these reference items in the store, such as
3304 <code>/gnu/store/…-bbb-render</code>, which is itself the result of “building”
3305 the origin we’ve seen above. The <code>#$output</code> reference corresponds
3306 to the build result of this <code>computed-file</code>, the complete file name
3307 of <code>video.ges</code> under <code>/gnu/store</code>.</li></ol><p>That’s quite a lot already! Of course, this real-world example is
3308 more intimidating than the toy examples you’d find in the manual, but
3309 really, pretty much everything’s there. Let’s see in more detail at
3310 what’s inside this gexp.</p><p>The gexp first imports a bunch of helper modules with <a href="https://guix.gnu.org/manual/en/html_node/Build-Utilities.html">build
3311 utilities</a>
3312 and tools to manipulate profiles and search path environment variables.
3313 The <code>for-each</code> call iterates over search path environment
3314 variables—<code>PATH</code>, <code>PYTHONPATH</code>, and so on—, setting them so that the
3315 <code>python</code> command is found and so that the needed Python modules are
3316 found.</p><p>The <code>with-imported-modules</code> form above indicates that the <code>(guix build utils)</code> and <code>(guix profiles)</code> modules, which are part of Guix, along
3317 with their dependencies (their <em>closure</em>), need to be imported in the
3318 build environment. What about <code>with-extensions</code>? Those <code>(guix …)</code>
3319 module indirectly depend on additional modules, provided by the
3320 <code>guile-gcrypt</code> package, hence this spec.</p><p>Next comes the
3321 <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/6977da4618814c790e767618da5cf9ec2cab0742/doc/atelier-reproductibilit%C3%A9/render-videos.scm#L77-106"><code>ges-&gt;webm</code></a>
3322 function which, as the name implies, takes a <code>.ges</code> file and produces a
3323 WebM video file by invoking <code>ges-launch-1.0</code>. The end result is a video
3324 containing the recording’s audio, the webcam and screen share (or slide
3325 deck), but not the chat.</p><h1>Opening and closing</h1><p>We have a WebM video, so we’re pretty much done, right? But… we’d also
3326 like to have an opening, showing the talk title and the speaker’s name,
3327 as well as a closing. How do we get that done?</p><p>Perhaps a bit of a sledgehammer, but it turns out that we chose to
3328 produce those still images with LaTeX/Beamer, from
3329 <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/6977da4618814c790e767618da5cf9ec2cab0742/doc/atelier-reproductibilit%C3%A9/opening.tex">these</a>

3332 function that takes a template <code>.tex</code> file, a speaker name and
3333 title. It copies the template, replaces placeholders with the
3334 speaker name and title, and runs <code>pdflatex</code> to produce the PDF.</li><li>The
3335 <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/6977da4618814c790e767618da5cf9ec2cab0742/doc/atelier-reproductibilit%C3%A9/render-videos.scm#L168-175"><code>pdf-&gt;bitmap</code></a>
3336 function takes a PDF and returns a suitably-sized JPEG.</li><li><a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/6977da4618814c790e767618da5cf9ec2cab0742/doc/atelier-reproductibilit%C3%A9/render-videos.scm#L177-200"><code>image-&gt;webm</code></a>
3337 takes that JPEG and invokes <code>ffmpeg</code> to render it as WebM, with the
3338 right resolution, frame rate, and audio track.</li></ol><p>With that in place, we define a sweet and small function that produces
3339 the opening WebM file for a given talk:</p><pre><code class="language-scheme">(define (opening title speaker)
3340 (image-&gt;webm
3341 (pdf-&gt;bitmap (latex-&gt;pdf (local-file "opening.tex") "opening.pdf"
3342 #:title title #:speaker speaker)
3343 "opening.jpg")
3344 "opening.webm" #:duration 5))</code></pre><p>We need one last function,
3345 <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/6977da4618814c790e767618da5cf9ec2cab0742/doc/atelier-reproductibilit%C3%A9/render-videos.scm#L216-236"><code>video-with-opening/closing</code></a>,
3346 that given a talk, an opening, and a closing, concatenates them by
3347 invoking <code>ffmpeg</code>.</p><h1>Putting it all together</h1><p>Now we have all the building blocks!</p><p>We use
3348 <a href="https://guix.gnu.org/manual/en/html_node/G_002dExpressions.html#index-local_002dfile"><code>local-file</code></a>
3349 to refer to the raw BBB data, taken from disk:</p><pre><code class="language-scheme">(define raw-bbb-data/monday

3358 personally-identifying information about participants), so this assumes
3359 that there’s a <code>bbb-video-data.monday</code> and a <code>bbb-video-data.tuesday</code> in
3360 the same directory as <code>render-videos.scm</code>.</p><p>For good measure, we define a

3396 with videos”, and that’s right! It’s also worth mentioning another
3397 approach: <a href="https://lang.video/">Racket’s video language</a>, which is
3398 designed to manipulate video abstractions, similar to GES but with a
3399 sweet high-level functional interface.</p><p>But look, this one’s different: it’s
3400 self-contained, it’s reproducible, and it has the right abstraction
3401 level. Self-contained is a big thing; it means you can run it and it
3402 knows what software to deploy, what environment variables to set, and so
3403 on, for each step of the pipeline. Granted, it could be simplified with
3404 appropriate high-level interfaces in Guix. But remember: the
3405 alternative is a makefile (“deployment-unaware”) completed by a <code>README</code>
3406 file giving a vague idea of the dependencies needed. The reproducible
3407 bit is pretty nice too (especially for a workshop <em>on</em> reproducibility).
3408 It also means there’s caching: videos or intermediate byproducts already
3409 in the store don’t need to be recomputed. Last, we have access to a
3410 general-purpose programming language where we can <em>build abstractions</em>,
3411 such as the <code>&lt;talk&gt;</code> data type, that makes the whole thing more pleasant
3412 to work with and more maintainable.</p><p>Hopefully that’ll inspire you to have a reproducible video pipeline for
3413 your next on-line event, or maybe that’ll inspire you to replace your
3414 old makefile and shelly habits for data processing!</p><p>High-performance computing (HPC) people might be wondering how to go
3415 from here and build “computing-resource-aware” or
3416 “storage-resource-aware” pipelines where each computing step could be
3417 submitted to the job scheduler of an HPC cluster and use distributed
3418 file systems for intermediate results rather than <code>/gnu/store</code>. If
3419 you’re one of these folks, do take a look at how the <a href="https://guixwl.org/">Guix Workflow
3420 Language</a> addresses these issues.</p><h1>Acknowledgments</h1><p>Thanks to Konrad Hinsen for valuable feedback on an earlier draft.</p><h4>About GNU Guix</h4><p><a href="https://guix.gnu.org">GNU Guix</a> is a transactional package manager and

3470
3471
3472 <p>It’s a great day for Bangladesh. It’s a great day for public health! Today, <a href="https://www.gnusolidario.org">GNU Solidario</a> and the International Federation of Medical Students Association, <a href="http://ifmsabd.org/">IFMSA Bangladesh</a>, have signed an initial <strong>5-year</strong> partnership on the grounds of the <strong>GNU Health Alliance of Academic and Research Institutions</strong>.</p>
3473
3474
3475
3476 <p>IFMSA Bangladesh is a non-for-profit, non-political organization that comprises <strong>3500+ medical students from over 65 schools of Medicine across Bangladesh.</strong> They are a solid organization, very well organized, with different standing committees and support divisions. </p>
3477
3478
3479
3480 <p>IFMSA vision and mission fits very well with those of GNU Solidario advancement of <strong>Social Medicine</strong>. IFMSA has projects on Public Health (reproductive health; personal hygiene; cardiovascular disease and cancer prevention, … ), Human rights and peace (campaigns to end violence against women; protection of the underprivileged elders and children.. ). I am positive the GNU Health ecosystem will help them reach their goals in each of their projects!</p>
3481
3482
3483
3484 <p>The GNU Health Alliance of Academic and Research Institutions is extremely happy to have IFMSA Bangladesh as a member. IFMSA Bangladesh joins now a group of outstanding researchers and institutions that have made phenomenal advancements in health informatics and contributions to public health. Some examples:</p>
3485
3486
3487
3488 <ul><li>The <strong>National University of Entre RÃos (UNER) </strong>has been awarded the project to use GNU Health as a real-time observatory for the <strong>COVID-19</strong> pandemic, by the Government of Argentina. In the context of the GNU Health Alliance, UNER has also developed the oral health package for GNU Health; and implemented the GNU Health Hospital Management Information System component in many public health care institutions in the country. The team from the UNER has traveled to Cameroon to implement GNU Health HMIS in several health facilities in the country, as well as training their health professionals.</li><li><strong>Thymbra</strong> Healthcare (R&amp;D Labs) has contributed the <strong>medical genetics</strong> and <strong>precision medicine</strong>. Currently, Thymbra is focused on <strong>MyGNUHealth</strong>, the GNU Health Personal Health Record (PHR) for <strong>KDE</strong> plasma mobile and desktops devices, and working on the integration of MyGNUHealth with the <strong>PinePhone</strong>.</li><li><strong>Khadas</strong> has signed an agreement to work on with the GNU Health community in <strong>Artificial Intelligence</strong> and medical imaging, as well on integrating Single Board Computers (SBCs) with GNU Health (the GNU Health in a Box project)</li></ul>
3489
3490
3491
3492 <p>The fact that an association of 3500+ medical students embrace GNU Health means that all these bright future doctors from Bangladesh will also bear the ethics and philosophy of Libre Software to their communities. Public Health can not be run by private corporations, nor by proprietary software.</p>
3493
3494
3495
3496 <p>IFMSA has 5 years ahead to make a wonderful revolution in the public health care system. Health institutions will be able to implement state-of-the-art health informatics. Medical students can learn GNU Health inside-out, and conduct workshops across the country in the Libre digital health ecosystem. Most importantly, I am positive GNU Health will provide a wonderful opportunity to improve the health promotion and disease prevention campaigns in Bangladesh.</p>
3497
3498
3499
3500 <p>As the president of GNU Solidario, I am truly honored and looking forward to start collaborating with our colleagues from Bangladesh, and, when the pandemic is over, be able to meet them in person. </p>
3501
3502
3503
3504 <p>My most sincere appreciation to IFMSA Bangladesh for becoming part of the GNU Health community. To the 3500+ members, a very warm welcome! </p>
3505
3506
3507
3508 <p>Let’s keep building communities that foster universal health care, freedom and social medicine around the world.</p>

3812 <title>GNU Health: Liberating our mobile computing</title>
3813 <guid>http://meanmicio.org/?p=2288</guid>
3814 <link>https://meanmicio.org/2021/06/04/liberating-our-mobile-computing/</link>
3815 <description> <p>Last week I got the PineTime, a free/libre smartwatch. In the past months, I’ve been working on MyGNUHealth and porting it to the PinePhone.</p>
3816
3817
3818
3819 <p>Why doing so? Because running free/libre operating systems and having control of the applications on your mobile phones and wearables is the right thing to do.</p>
3820
3821
3822
3823 <figure class="wp-block-image size-large is-style-default"><a href="https://meanmicio.files.wordpress.com/2021/06/pinetime_pinephone_kdeplasma1.jpg"><img alt="" class="wp-image-2292" src="https://meanmicio.files.wordpress.com/2021/06/pinetime_pinephone_kdeplasma1.jpg?w=1024" /></a></figure>
3824
3825
3826
3827 <p>Yesterday, I told myself: “This is the day to move away from Android and take control over my phone”. And I made the switch. Now I am using a PinePhone on Manjaro running KDE plasma mobile. I have also switched my smartwatch to the PineTime.</p>
3828
3829
3830
3831 <p>The mobile phone and smartwatch were the last pieces of hardware and software to liberate. All my computing is now libre. No proprietary operating systems, no closed-source applications. Not on my laptop, not in my desktop, not on my phone.</p>
3832
3833
3834
3835 <h3>Facing and overcoming the social pressure</h3>
3836
3837
3838
3839 <p>At the moment I ditched Android, I felt an immense sense of relief and happiness. It took me back 30 years ago, early FreeBSD and GNU/Linux times, being in control of every component of my computer.</p>
3840
3841
3842
3843 <p>We can not put our daily life activities, electronic transactions and data in the hands of the corporations. Android phones shipped today are full of “bloatware” and closed-source applications. We can safely call most of those applications spyware. </p>
3844
3845
3846
3847 <p>The PinePhone is a libre computer, with a phone. All the applications are Libre Software. I have SSH, most of the cool KDE plasma applications I enjoy in the desktop, I can have them now in my pocket. Again, most importantly, I am free.</p>
3848
3849
3850
3851 <p>Of course, freedom comes with a price. The price to face social and corporate pressure. For instance, somebody asked me yesterday how to deal with banking without the app. My answer was, I never used an app for banking. Running a proprietary financial application is shooting at the heart of your privacy. If your bank does not let you do your transactions from any standard web browser, then change your bank. Quick digression… the financial system and the big technological corporations are desperately trying to get rid of good all coins and bills. This is yet another attack on our privacy. Nobody needs to know when, where and what I buy. </p>
3852
3853
3854
3855 <h3>A brighter future depends on us</h3>
3856
3857
3858
3859 <p>Some people might argue that this technology might not be ready for prime time, yet. I would say that I am ok with it, and the more we join, the more feedback we provide, and the better end result we’ll get.</p>
3860
3861
3862
3863 <p>The Pine64 project is mainly a community-oriented ecosystem. Its hardware, operating system and applications are from the community and for the community. I am developing MyGNUHealth Personal Health Record to be run on KDE Plasma, both for desktop and for the PinePhone and other Libre mobile devices. It is my commitment with freedom, privacy and universal healthcare to deliver health informatics in Libre, privacy focused platforms that anyone can adopt.</p>
3864
3865
3866
3867 <figure class="wp-block-image size-large is-style-default"><a href="https://meanmicio.files.wordpress.com/2021/06/pinetime_mygnuhealth_pinephone.jpg"><img alt="" class="wp-image-2294" src="https://meanmicio.files.wordpress.com/2021/06/pinetime_mygnuhealth_pinephone.jpg?w=1024" /></a><figcaption>MyGNUHealth Personal Health Record running on the Desktop and on the PinePhone. The PineTime smartwatch as the next companion for MyGNUHealth. All these components are privacy focused, Free/Libre Software and hardware.</figcaption></figure>
3868
3869
3870
3871 <p>It depends on you to be prisoner of the corporation and massive surveillance systems, or to be in full control of your programming, health information and life. It takes commitment to achieve it… some components might be too bleeding edge or the camera might not have the highest resolutions and you won’t have the Whatsapp “app” (removing that application would actually be a blessing). It’s a very small price to pay for freedom and privacy. It’s a very small price to pay for the advancement of our society.</p>
3872
3873
3874
3875 <figure class="wp-block-image size-large is-style-default"><a href="https://meanmicio.files.wordpress.com/2021/06/siglo_pinetime_firmware_upgrade.png"><img alt="" class="wp-image-2296" src="https://meanmicio.files.wordpress.com/2021/06/siglo_pinetime_firmware_upgrade.png?w=1024" /></a><figcaption>InfiniTime firmware upgrade using Siglo. </figcaption></figure>
3876
3877
3878
3879 <p>It’s been many years since I’ve been in the look out for a truly libre phone. After many projects that succumbed, the PinePhone is the first one that has gained momentum. Please support the PinePhone project. Support KDE plasma mobile. Support Arch, Manjaro, openSUSE, FreeBSD or your favorite Libre operating system. Support those who make Libre convergent applications that can be run on mobile devices, like Kirigami. Support InfiniTime and any free/libre firmware for smartwatches, as well as their companions as Siglo or Amazfish.</p>
3880
3881
3882
3883 <p>The future of Libre mobile computing is now, more than ever, in your hands.</p>
3884
3885

3992 <h2>About GNU Parallel</h2>
3993
3994 <p>GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel.
3995 <br />
3996 </p>
3997 <p>If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops.
3998 <br />
3999 </p>
4000 <p>GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs.
4001 <br />
4002 </p>
4003 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
4004 <br />
4005 </p>
4006 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
4007 <br />
4008 </p>
4009 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
4010 <br />
4011 </p>
4012 <p> find . -name '*.jpg' |
4013 <br />
4014 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
4015 <br />
4016 </p>

4088 <h2>About GNU SQL</h2>
4089
4090 <p>GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries.
4091 <br />
4092 </p>
4093 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.
4094 <br />

4103 <h2>About GNU Niceload</h2>
4104
4105 <p>GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.<br />
