91 <title>Applied Pokology: Array boundaries and closures in Poke</title>
92 <link>http://jemarch.net/pokology-03102019.html</link>
93 <content:encoded>Poke arrays are rather peculiar. One of their seemingly
94 bizarre characteristics is the fact that the expressions
95 calculating their boundaries (when they are bounded) evaluate
96 in their own lexical environment, which is captured. In other
97 words: the expressions denoting the boundaries of Poke arrays
98 conform closures. Also, the way they evaluate may be
99 surprising. This is no capricious.</content:encoded>

318 <h2>About GNU Parallel</h2>
319
320 <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.
321 <br />
322 </p>
323 <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.
324 <br />
325 </p>
326 <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.
327 <br />
328 </p>
329 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
330 <br />
331 </p>
332 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
333 <br />
334 </p>
335 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
336 <br />
337 </p>

414 <h2>About GNU SQL</h2>
415
416 <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.
417 <br />
418 </p>
419 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.
420 <br />

429 <h2>About GNU Niceload</h2>
430
431 <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 />

454 <link>https://meanmicio.org/2021/08/15/gnu-health-emergency-response-in-haiti/</link>
455 <content:encoded><p>Yesterday, yet another devastating earthquake hit the southern area of Haiti. </p>
456
457
458
459 <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>
460
461
462
463 <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>

473
474
475 <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>
476
477
478
479 <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>

485
486
487 <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>
488
489
490
491 <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>

617 <content:encoded><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>
618 <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></content:encoded>

624 <link>https://taler.net/en/news/2021-08.html</link>
625 <content:encoded><article>
626 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.

636 GNUnet 0.15.0 released
637 </h1>
638 <p>
639 We are pleased to announce the release of GNUnet 0.15.0.
640 <br />
641 This is a new major release. It breaks protocol compatibility with the 0.14.x versions.
642 Please be aware that Git master is thus henceforth
643 <b>
644 INCOMPATIBLE
645 </b>
646 with
647 the 0.14.x GNUnet network, and interactions between old and new peers
648 will result in issues. 0.14.x peers will be able to communicate with Git
649 master or 0.14.x peers, but some services - in particular GNS - will not be compatible.
650 <br />
651 The MESSENGER service goes out of experimental to be used by
652 libraries and applications as dependency. It handles decentralized
653 messaging in flexible groups by using the CADET service and messages
654 can be signed with your ego from the IDENTITY service. The service
655 is still in an early stage, so its protocol (currently version 0.1)
656 will likely adapt or change in future releases to some degree.
657 <br />
658 In terms of usability, users should be aware that there are still
659 <b>
660 a number of known open issues
661 </b>
662 in particular with respect to ease
663 of use, but also some critical privacy issues especially for mobile users.
664 Also, the nascent network is tiny and thus unlikely to
665 provide good anonymity or extensive amounts of interesting information.
666 As a result, the 0.15.0 release is still
667 <b>
668 only suitable for early adopters
669 with some reasonable pain tolerance
670 </b>
671 .

890 <title>GNU Guix: Taming the ‘stat’ storm with a loader cache</title>
891 <link>https://guix.gnu.org/blog/2021/taming-the-stat-storm-with-a-loader-cache/</link>
892 <content:encoded><p>It was one of these days where some of us on IRC were rehashing that old
893 problem—that application startup in Guix causes a
894 “<a href="https://linux.die.net/man/2/stat"><code>stat</code></a> storm”—and lamenting the
895 lack of a solution when suddenly, Ricardo
896 <a href="https://logs.guix.gnu.org/guix/2020-11-24.log#183934">proposes</a> what,
897 in hindsight, looks like an obvious solution: “maybe we could use a
898 per-application ld cache?”. A moment where collective thinking exceeds
899 the sum of our individual thoughts. The result is one of the many
900 features that made it in the <code>core-updates</code> branch, slated to be merged
901 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
902 like and where they come from. Loading an
903 <a href="https://en.wikipedia.org/wiki/Executable_and_Linkable_Format">ELF</a>
904 executable involves loading the shared libraries (the <code>.so</code> files, for
905 “shared objects”) it depends on, recursively. This is the job of the
906 <em>loader</em> (or <em>dynamic linker</em>), <code>ld.so</code>, which is part of the GNU C
907 Library (glibc) package. What shared libraries an executable like that
908 of Emacs depends on? The <code>ldd</code> command answers that question:</p><pre><code>$ ldd $(type -P .emacs-27.2-real)
909 linux-vdso.so.1 (0x00007fff565bb000)
910 libtiff.so.5 =&gt; /gnu/store/l1wwr5c34593gqxvp34qbwdkaf7xhdbd-libtiff-4.2.0/lib/libtiff.so.5 (0x00007fd5aa2b1000)
911 libjpeg.so.62 =&gt; /gnu/store/5khkwz9g6vza1n4z8xlmdrwhazz7m8wp-libjpeg-turbo-2.0.5/lib/libjpeg.so.62 (0x00007fd5aa219000)
912 libpng16.so.16 =&gt; /gnu/store/3x2kak8abb6z2klch72kfff2qxzv00pj-libpng-1.6.37/lib/libpng16.so.16 (0x00007fd5aa1e4000)

917 $ ldd $(type -P .emacs-27.2-real) | wc -l
918 89</code></pre><p>(If you’re wondering why we’re looking at <code>.emacs-27.2-real</code> rather than
919 <code>emacs-27.2</code>, it’s because in Guix the latter is a tiny shell wrapper
920 around the former.)</p><p>To load a graphical program like Emacs, the loader needs to load more
921 than 80 shared libraries! Each is in its own <code>/gnu/store</code> sub-directory
922 in Guix, one directory per package.</p><p>But how does <code>ld.so</code> know where to find these libraries in the first
923 place? In Guix, during the link phase that produces an ELF file
924 (executable or shared library), we tell the
925 <a href="https://en.wikipedia.org/wiki/Linker_%28computing%29">linker</a> to
926 populate the <code>RUNPATH</code> entry of the ELF file with the list of
927 directories where its dependencies may be found. This is done by
928 passing
929 <a href="https://sourceware.org/binutils/docs/ld/Options.html#index-_002drpath_003ddir"><code>-rpath</code></a>
930 options to the linker, which Guix’s <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/ld-wrapper.in">“linker
931 wrapper”</a>
932 takes care of. The <code>RUNPATH</code> is the <em>run-time library search path</em>:
933 it’s a colon-separated list of directories where <code>ld.so</code> will look for
934 shared libraries when it loads an ELF file. We can look at the
935 <code>RUNPATH</code> of our Emacs executable like this:</p><pre><code>$ objdump -x $(type -P .emacs-27.2-real) | grep RUNPATH
936 RUNPATH /gnu/store/fa6wj5bxkj5ll1d7292a70knmyl7a0cr-glibc-2.31/lib:/gnu/store/01b4w3m6mp55y531kyi1g8shh722kwqm-gcc-7.5.0-lib/lib:/gnu/store/l1wwr5c34593gqxvp34qbwdkaf7xhdbd-libtiff-4.2.0/lib:/gnu/store/5khkwz9g6vza1n4z8xlmdrwhazz7m8wp-libjpeg-turbo-2.0.5/lib:[…]</code></pre><p>This <code>RUNPATH</code> has 39 entries, which roughly corresponds to the number
937 of direct dependencies of the executable—dependencies are listed as
938 <code>NEEDED</code> entries in the ELF file:</p><pre><code>$ objdump -x $(type -P .emacs-27.2-real) | grep NEED | head
939 NEEDED libtiff.so.5
940 NEEDED libjpeg.so.62
941 NEEDED libpng16.so.16
942 NEEDED libz.so.1
943 NEEDED libgif.so.7
944 NEEDED libXpm.so.4
945 NEEDED libgtk-3.so.0
946 NEEDED libgdk-3.so.0
947 NEEDED libpangocairo-1.0.so.0
948 NEEDED libpango-1.0.so.0
949 $ objdump -x $(type -P .emacs-27.2-real) | grep NEED | wc -l
950 52</code></pre><p>(Some of these <code>.so</code> files live in the same directory, which is why
951 there are more <code>NEEDED</code> entries than directories in the <code>RUNPATH</code>.)</p><p>A system such as Debian that follows the <a href="https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard">file system hierarchy
952 standard</a>
953 (FHS), where all libraries are in <code>/lib</code> or <code>/usr/lib</code>, does not have to
954 bother with <code>RUNPATH</code>: all <code>.so</code> files are known to be found in one of
955 these two “standard” locations. Anyway, let’s get back to our initial
956 topic: the “<code>stat</code> storm”.</p><h1>Walking search paths</h1><p>As you can guess, when we run Emacs, the loader first needs to locate
957 and load the 80+ shared libraries it depends on. That’s where things
958 get pretty inefficient: the loader will search each <code>.so</code> file Emacs
959 depends on in one of the 39 directories listed in its <code>RUNPATH</code>.
960 Likewise, when it finally finds <code>libgtk-3.so</code>, it’ll look for its
961 dependencies in each of the directories in its <code>RUNPATH</code>. We can see
962 that at play by tracing system calls with the
963 <a href="https://strace.io/"><code>strace</code></a> command:</p><pre><code>$ strace -c emacs --version

1009 […]</code></pre><p>Above is the sequence where we see <code>ld.so</code> look for <code>libpng16.so.16</code>,
1010 searching in locations where we <em>know</em> it’s not going to find it. A bit
1011 ridiculous. How does this affect performance? The impact is small in
1012 the most favorable case—on a hot cache, with fast solid state device
1013 (SSD) storage. But it likely has a visible effect in other cases—on a
1014 cold cache, with a slower spinning hard disk drive (HDD), on a network
1015 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
1016 sense: we know from the start that <code>libpng.so</code> may only be found in
1017 <code>/gnu/store/…-libpng-1.6.37</code>, no need to look elsewhere. In fact, it’s
1018 not new: glibc has had such a cache “forever”; it’s the
1019 <code>/etc/ld.so.cache</code> file you can see on FHS distros and which is
1020 typically created by running
1021 <a href="https://linux.die.net/man/8/ldconfig"><code>ldconfig</code></a> when a package has
1022 been installed. Roughly, the cache maps library <code>SONAME</code>s, such as
1023 <code>libpng16.so.16</code>, to their file name on disk, say
1024 <code>/usr/lib/libpng16.so.16</code>.</p><p>The problem is that this cache is inherently system-wide: it assumes
1025 that there is only <em>one</em> <code>libpng16.so</code> on the system; any binary that
1026 depends on <code>libpng16.so</code> will load it from its one and only location.
1027 This models perfectly matches the FHS, but it’s at odds with the
1028 flexibility offered by Guix, where several variants or versions of the
1029 library can coexist on the system, used by different applications.
1030 That’s the reason why Guix and other non-FHS distros such as NixOS or
1031 GoboLinux typically <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/base.scm?id=a92dfbce30777de6ca05031e275410cf9f56c84c#n716">turn
1032 off</a>
1033 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
1034 we could <em>adapt</em> glibc’s loader cache to our setting: instead of a
1035 system-wide cache, we’d have a <em>per-application loader cache</em>. As one
1036 of the last package <a href="https://guix.gnu.org/manual/en/html_node/Build-Phases.html">build
1037 phases</a>,
1038 we’d run <code>ldconfig</code> to create <code>etc/ld.so.cache</code> within that package’s
1039 <code>/gnu/store</code> sub-directory. We then need to modify the loader so it
1040 would look for <code>${ORIGIN}/../etc/ld.so.cache</code> instead of
1041 <code>/etc/ld.so.cache</code>, where <code>${ORIGIN}</code> is the location of the ELF file
1042 being loaded. A discussion of these changes is <a href="https://issues.guix.gnu.org/44899">in the issue
1043 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
1044 patch</a>
1045 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
1046 phase</a>.
1047 In short, the <code>make-dynamic-linker-cache</code> phase computes the set of
1048 direct and indirect dependencies of an ELF file using the
1049 <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/guix/build/gremlin.scm?id=0236013cd0fc86ff4a042885c735e3f36a7f5c25#n265"><code>file-needed/recursive</code></a>
1050 procedure and derives from that the library search path, creates a
1051 temporary <code>ld.so.conf</code> file containing this search path for use by
1052 <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
1053 uses this new loader cache:</p><pre><code>$ strace -c /gnu/store/ijgcbf790z4x2mkjx2ha893hhmqrj29j-emacs-27.2/bin/emacs --version

1071 100.00 0.010144 8 1128 24 total</code></pre><p>Compared to what we have above, the total number of system calls has
1072 been divided by 3, and the fraction of erroneous system calls goes from
1073 67% to 0.2%. Quite a difference! We count on you, dear users, to <a href="https://guix.gnu.org/en/contact">let
1074 us know</a> how this impacts load time for
1075 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
1076 then Nix, Guix, and other distros, the benefits of flexible file layouts
1077 rather than the rigid Unix-inherited FHS have been demonstrated—nowadays
1078 I see it as an antidote to opaque and bloated application bundles à la
1079 Docker. Luckily, few of our system tools have FHS assumptions baked in,
1080 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
1081 installation directory
1082 categorization</a>
1083 in the early days rather than hard-coded directory names. The loader
1084 cache is one of the few exceptions. Adapting it to a non-FHS context is
1085 fruitful for Guix and for the other distros and packaging tools in a
1086 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
1087 run-time systems rely on search paths—<code>GUILE_LOAD_PATH</code> for Guile,
1088 <code>PYTHONPATH</code> for Python, <code>OCAMLPATH</code> for OCaml, etc.—and are equally
1089 prone to stormy application startups. Unlike ELF, they do not have a
1090 mechanism akin to <code>RUNPATH</code>, let alone a run-time search path cache. We
1091 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

1111 <br />
1112 =================
1113 <br />
1114 </p>
1115 <p>The GNU C Library version 2.34 is now available.
1116 <br />
1117 </p>
1118 <p>The GNU C Library is used as <strong>the</strong> C library in the GNU system and
1119 <br />
1120 in GNU/Linux systems, as well as many other systems that use Linux
1121 <br />
1122 as the kernel.
1123 <br />
1124 </p>
1125 <p>The GNU C Library is primarily designed to be a portable
1126 <br />
1127 and high performance C library. It follows all relevant
1128 <br />
1129 standards including ISO C11 and POSIX.1-2017. It is also
1130 <br />
1131 internationalized and has one of the most complete
1132 <br />
1133 internationalization interfaces known.
1134 <br />

1149 <p>NEWS for version 2.34
1150 <br />
1151 =====================
1152 <br />
1153 </p>
1154 <p>Major new features:
1155 <br />
1156 </p>
1157 <ul>
1158 <li>In order to support smoother in-place-upgrades and to simplify
1159 </li>
1160 </ul><p> the implementation of the runtime all functionality formerly
1161 <br />
1162 implemented in the libraries libpthread, libdl, libutil, libanl has
1163 <br />
1164 been integrated into libc. New applications do not need to link with
1165 <br />
1166 -lpthread, -ldl, -lutil, -lanl anymore. For backwards compatibility,
1167 <br />
1168 empty static archives libpthread.a, libdl.a, libutil.a, libanl.a are
1169 <br />
1170 provided, so that the linker options keep working. Applications which
1171 <br />
1172 have been linked against glibc 2.33 or earlier continue to load the
1173 <br />
1174 corresponding shared objects (which are now empty). The integration
1175 <br />
1176 of those libraries into libc means that additional symbols become
1177 <br />
1178 available by default. This can cause applications that contain weak
1179 <br />
1180 references to take unexpected code paths that would only have been
1181 <br />
1182 used in previous glibc versions when e.g. preloading libpthread.so.0,
1183 <br />
1184 potentially exposing application bugs.
1185 <br />
1186 </p>
1187 <ul>
1188 <li>When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined,
1189 </li>
1190 </ul><p> PTHREAD_STACK_MIN is no longer constant and is redefined to
1191 <br />
1192 sysconf(_SC_THREAD_STACK_MIN). This supports dynamic sized register
1193 <br />
1194 sets for modern architectural features like Arm SVE.
1195 <br />
1196 </p>
1197 <ul>
1198 <li>Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ. When _DYNAMIC_STACK_SIZE_SOURCE
1199 </li>
1200 </ul><p> or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are no longer
1201 <br />
1202 constant on Linux. MINSIGSTKSZ is redefined to sysconf(_SC_MINSIGSTKSZ)
1203 <br />
1204 and SIGSTKSZ is redefined to sysconf (_SC_SIGSTKSZ). This supports
1205 <br />
1206 dynamic sized register sets for modern architectural features like
1207 <br />
1208 Arm SVE.
1209 <br />
1210 </p>
1211 <ul>
1212 <li>The dynamic linker implements the --list-diagnostics option, printing
1213 </li>
1214 </ul><p> a dump of information related to IFUNC resolver operation and
1215 <br />
1216 glibc-hwcaps subdirectory selection.
1217 <br />
1218 </p>
1219 <ul>
1220 <li>On Linux, the function execveat has been added. It operates similar to
1221 </li>
1222 </ul><p> execve and it is is already used to implement fexecve without requiring
1223 <br />
1224 /proc to be mounted. However, different than fexecve, if the syscall is not
1225 <br />
1226 supported by the kernel an error is returned instead of trying a fallback.
1227 <br />
1228 </p>
1229 <ul>
1230 <li>The ISO C2X function timespec_getres has been added.
1231 </li>
1232 </ul>
1233 <ul>
1234 <li>The feature test macro <em>_STDC_WANT_IEC_60559_EXT_</em>, from draft ISO
1235 </li>
1236 </ul><p> C2X, is supported to enable declarations of functions defined in Annex F
1237 <br />
1238 of C2X. Those declarations are also enabled when
1239 <br />
1240 <em>_STDC_WANT_IEC_60559_BFP_EXT_</em>, as specified in TS 18661-1, is
1241 <br />
1242 defined, and when _GNU_SOURCE is defined.
1243 <br />
1244 </p>
1245 <ul>
1246 <li>On powerpc64*, glibc can now be compiled without scv support using the
1247 </li>
1248 </ul><p> --disable-scv configure option.
1249 <br />
1250 </p>
1251 <ul>
1252 <li>Add support for 64-bit time_t on configurations like x86 where time_t
1253 </li>
1254 </ul><p> is traditionally 32-bit. Although time_t still defaults to 32-bit on
1255 <br />
1256 these configurations, this default may change in future versions.
1257 <br />
1258 This is enabled with the _TIME_BITS preprocessor macro set to 64 and is
1259 <br />
1260 only supported when LFS (_FILE_OFFSET_BITS=64) is also enabled. It is
1261 <br />
1262 only enabled for Linux and the full support requires a minimum kernel
1263 <br />
1264 version of 5.1.
1265 <br />
1266 </p>
1267 <ul>
1268 <li>The main gconv-modules file in glibc now contains only a small set of
1269 </li>
1270 </ul><p> essential converter modules and the rest have been moved into a supplementary
1271 <br />
1272 configuration file gconv-modules-extra.conf in the gconv-modules.d directory
1273 <br />
1274 in the same GCONV_PATH. Similarly, external converter modules directories
1275 <br />
1276 may have supplementary configuration files in a gconv-modules.d directory
1277 <br />
1278 with names ending with .conf to logically classify the converter modules in
1279 <br />
1280 that directory.
1281 <br />
1282 </p>
1283 <ul>
1284 <li>On Linux, a new tunable, glibc.pthread.stack_cache_size, can be used
1285 </li>
1286 </ul><p> to configure the size of the thread stack cache.
1287 <br />
1288 </p>
1289 <ul>
1290 <li>The function _Fork has been added as an async-signal-safe fork replacement
1291 </li>
1292 </ul><p> since Austin Group issue 62 droped the async-signal-safe requirement for
1293 <br />
1294 fork (and it will be included in the future POSIX standard). The new _Fork
1295 <br />
1296 function does not run any atfork function neither resets any internal state
1297 <br />
1298 or lock (such as the malloc one), and only sets up a minimal state required
1299 <br />
1300 to call async-signal-safe functions (such as raise or execve). This function
1301 <br />
1302 is currently a GNU extension.
1303 <br />
1304 </p>
1305 <ul>
1306 <li>On Linux, the close_range function has been added. It allows efficiently
1307 </li>
1308 </ul><p> closing a range of file descriptors on recent kernels (version 5.9).
1309 <br />
1310 </p>
1311 <ul>
1312 <li>The function closefrom has been added. It closes all file descriptors
1313 </li>
1314 </ul><p> greater than or equal to a given integer. This function is a GNU extension,
1315 <br />
1316 although it is also present in other systems.
1317 <br />
1318 </p>
1319 <ul>
1320 <li>The posix_spawn_file_actions_addclosefrom_np function has been added,
1321 </li>
1322 </ul><p> enabling posix_spawn and posix_spawnp to close all file descriptors greater
1323 <br />
1324 than or equal to a given integer. This function is a GNU extension,
1325 <br />
1326 although Solaris also provides a similar function.
1327 <br />
1328 </p>
1329 <p>Deprecated and removed features, and other changes affecting compatibility:
1330 <br />
1331 </p>
1332 <ul>
1333 <li>The function pthread_mutex_consistent_np has been deprecated; programs
1334 </li>
1335 </ul><p> should use the equivalent standard function pthread_mutex_consistent
1336 <br />
1337 instead.
1338 <br />
1339 </p>
1340 <ul>
1341 <li>The function pthread_mutexattr_getrobust_np has been deprecated;
1342 </li>
1343 </ul><p> programs should use the equivalent standard function
1344 <br />
1345 pthread_mutexattr_getrobust instead.
1346 <br />
1347 </p>
1348 <ul>
1349 <li>The function pthread_mutexattr_setrobust_np has been deprecated;
1350 </li>
1351 </ul><p> programs should use the equivalent standard function
1352 <br />
1353 pthread_mutexattr_setrobust instead.
1354 <br />
1355 </p>
1356 <ul>
1357 <li>The function pthread_yield has been deprecated; programs should use
1358 </li>
1359 </ul><p> the equivalent standard function sched_yield instead.
1360 <br />
1361 </p>
1362 <ul>
1363 <li>The function inet_neta declared in &lt;arpa/inet.h&gt; has been deprecated.
1364 </li>
1365 </ul>
1366 <ul>
1367 <li>Various rarely-used functions declared in &lt;resolv.h&gt; and
1368 </li>
1369 </ul><p> &lt;arpa/nameser.h&gt; have been deprecated. Applications are encouraged to
1370 <br />
1371 use dedicated DNS processing libraries if applicable. For &lt;resolv.h&gt;,
1372 <br />
1373 this affects the functions dn_count_labels, fp_nquery, fp_query,
1374 <br />
1375 fp_resstat, hostalias, loc_aton, loc_ntoa, p_cdname, p_cdnname,
1376 <br />
1377 p_class, p_fqname, p_fqnname, p_option, p_query, p_rcode, p_time,
1378 <br />
1379 p_type, putlong, putshort, res_hostalias, res_isourserver,
1380 <br />
1381 res_nameinquery, res_queriesmatch, res_randomid, sym_ntop, sym_ntos,
1382 <br />
1383 sym_ston. For &lt;arpa/nameser.h&gt;, the functions ns_datetosecs,
1384 <br />
1385 ns_format_ttl, ns_makecanon, ns_parse_ttl, ns_samedomain, ns_samename,
1386 <br />
1387 ns_sprintrr, ns_sprintrrf, ns_subdomain have been deprecated.
1388 <br />
1389 </p>
1390 <ul>
1391 <li>Various symbols previously defined in libresolv have been moved to libc
1392 </li>
1393 </ul><p> in order to prepare for libresolv moving entirely into libc (see earlier
1394 <br />
1395 entry for merging libraries into libc). The symbols __dn_comp,
1396 <br />
1397 __dn_expand, __dn_skipname, __res_dnok, __res_hnok, __res_mailok,
1398 <br />
1399 __res_mkquery, __res_nmkquery, __res_nquery, __res_nquerydomain,
1400 <br />
1401 __res_nsearch, __res_nsend, __res_ownok, __res_query, __res_querydomain,
1402 <br />
1403 __res_search, __res_send formerly in libresolv have been renamed and no
1404 <br />
1405 longer have a __ prefix. They are now available in libc.
1406 <br />
1407 </p>
1408 <ul>
1409 <li>The pthread cancellation handler is now installed with SA_RESTART and
1410 </li>
1411 </ul><p> pthread_cancel will always send the internal SIGCANCEL on a cancellation
1412 <br />
1413 request. It should not be visible to applications since the cancellation
1414 <br />
1415 handler should either act upon cancellation (if asynchronous cancellation
1416 <br />
1417 is enabled) or ignore the cancellation internal signal. However there are
1418 <br />
1419 buggy kernel interfaces (for instance some CIFS versions) that could still
1420 <br />
1421 see a spurious EINTR error when cancellation interrupts a blocking syscall.
1422 <br />
1423 </p>
1424 <ul>
1425 <li>Previously, glibc installed its various shared objects under versioned
1426 </li>
1427 </ul><p> file names such as libc-2.33.so. The ABI sonames (e.g., libc.so.6)
1428 <br />
1429 were provided as symbolic links. Starting with glibc 2.34, the shared
1430 <br />
1431 objects are installed under their ABI sonames directly, without
1432 <br />
1433 symbolic links. This increases compatibility with distribution
1434 <br />
1435 package managers that delete removed files late during the package
1436 <br />
1437 upgrade or downgrade process.
1438 <br />
1439 </p>
1440 <ul>
1441 <li>The symbols mallwatch and tr_break are now deprecated and no longer used in
1442 </li>
1443 </ul><p> mtrace. Similar functionality can be achieved by using conditional
1444 <br />
1445 breakpoints within mtrace functions from within gdb.
1446 <br />
1447 </p>
1448 <ul>
1449 <li>The __morecore and __after_morecore_hook malloc hooks and the default
1450 </li>
1451 </ul><p> implementation __default_morecore have been removed from the API. Existing
1452 <br />
1453 applications will continue to link against these symbols but the interfaces
1454 <br />
1455 no longer have any effect on malloc.
1456 <br />
1457 </p>
1458 <ul>
1459 <li>Debugging features in malloc such as the MALLOC_CHECK_ environment variable
1460 </li>
1461 </ul><p> (or the glibc.malloc.check tunable), mtrace() and mcheck() have now been
1462 <br />
1463 disabled by default in the main C library. Users looking to use these
1464 <br />
1465 features now need to preload a new debugging DSO libc_malloc_debug.so to get
1466 <br />
1467 this functionality back.
1468 <br />
1469 </p>
1470 <ul>
1471 <li>The deprecated functions malloc_get_state and malloc_set_state have been
1472 </li>
1473 </ul><p> moved from the core C library into libc_malloc_debug.so. Legacy applications
1474 <br />
1475 that still use these functions will now need to preload libc_malloc_debug.so
1476 <br />
1477 in their environment using the LD_PRELOAD environment variable.
1478 <br />
1479 </p>
1480 <ul>
1481 <li>The deprecated memory allocation hooks __malloc_hook, __realloc_hook,
1482 </li>
1483 </ul><p> __memalign_hook and __free_hook are now removed from the API. Compatibility
1484 <br />
1485 symbols are present to support legacy programs but new applications can no
1486 <br />
1487 longer link to these symbols. These hooks no longer have any effect on glibc
1488 <br />
1489 functionality. The malloc debugging DSO libc_malloc_debug.so currently
1490 <br />
1491 supports hooks and can be preloaded to get this functionality back for older
1492 <br />
1493 programs. However this is a transitional measure and may be removed in a
1494 <br />
1495 future release of the GNU C Library. Users may port away from these hooks by
1496 <br />
1497 writing and preloading their own malloc interposition library.
1498 <br />
1499 </p>
1500 <p>Changes to build and runtime requirements:
1501 <br />
1502 </p>
1503 <ul>
1504 <li>On Linux, the shm_open, sem_open, and related functions now expect the
1505 </li>
1506 </ul><p> file shared memory file system to be mounted at /dev/shm. These functions
1507 <br />
1508 no longer search among the system's mount points for a suitable
1509 <br />
1510 replacement if /dev/shm is not available.
1511 <br />
1512 </p>
1513 <p>Security related changes:
1514 <br />
1515 </p>
1516 <p> CVE-2021-27645: The nameserver caching daemon (nscd), when processing
1517 <br />
1518 a request for netgroup lookup, may crash due to a double-free,
1519 <br />
1520 potentially resulting in degraded service or Denial of Service on the
1521 <br />
1522 local system. Reported by Chris Schanzle.
1523 <br />
1524 </p>
1525 <p> CVE-2021-33574: The mq_notify function has a potential use-after-free
1526 <br />
1527 issue when using a notification type of SIGEV_THREAD and a thread
1528 <br />
1529 attribute with a non-default affinity mask.
1530 <br />
1531 </p>
1532 <p> CVE-2021-35942: The wordexp function may overflow the positional
1533 <br />
1534 parameter number when processing the expansion resulting in a crash.
1535 <br />
1536 Reported by Philippe Antoine.

2038 * Noteworthy changes in release 3.8 (2021-08-01) [stable]<br />
2039 <br />
2040 ** Incompatible changes<br />
2041 <br />
2042 diff no longer treats a closed stdin as representing an absent file<br />
2043 in usage like 'diff --new-file - foo &lt;&amp;-'. This feature was rarely<br />
2044 if ever used and was not portable to POSIX platforms that reopen<br />
2045 stdin on exec, such as SELinux if the process underwent an AT_SECURE<br />
2046 transition, or HP-UX even if not setuid.<br />
2047 [bug#33965 introduced in 2.8]<br />
2048 <br />
2049 ** Bug fixes<br />
2050 <br />
2051 diff and related programs no longer get confused if stdin, stdout,<br />
2052 or stderr are closed. Previously, they sometimes opened files into<br />
2053 file descriptors 0, 1, or 2 and then mistakenly did I/O with them<br />
2054 that was intended for stdin, stdout, or stderr.<br />
2055 [bug#33965 present since "the beginning"]<br />
2056 <br />
2057 cmp, diff and sdiff no longer treat negative command-line<br />
2058 option-arguments as if they were large positive numbers.<br />

2179 <h2>About GNU Parallel</h2>
2180
2181 <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.
2182 <br />
2183 </p>
2184 <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.
2185 <br />
2186 </p>
2187 <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.
2188 <br />
2189 </p>
2190 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
2191 <br />
2192 </p>
2193 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
2194 <br />
2195 </p>
2196 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
2197 <br />
2198 </p>
2199 <p> find . -name '*.jpg' |
2200 <br />
2201 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
2202 <br />
2203 </p>

2275 <h2>About GNU SQL</h2>
2276
2277 <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.
2278 <br />
2279 </p>
2280 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.

2290 <h2>About GNU Niceload</h2>
2291
2292 <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 />

2319 <content:encoded><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>
2320
2321
2322
2323 <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>
2324
2325
2326
2327 <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>

2345
2346
2347 <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>
2348
2349
2350
2351 <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>

2535 <title>Christopher Allan Webber: Hello, I'm Chris Lemmer-Webber, and I'm nonbinary trans-femme</title>
2536 <link>http://dustycloud.org/blog/nonbinary-trans-femme/</link>
2537 <content:encoded><p><img alt="A picture of Chris and Morgan together" src="https://dustycloud.org/gfx/goodies/chris-and-morgan-2021-06-27.jpg" /></p>
2538 <p>I recently came out as nonbinary trans-femme.
2539 That's a picture of me on the left, with my spouse Morgan Lemmer-Webber
2540 on the right.</p>
2541 <p>In a sense, not much has changed, and so much has changed.
2542 I've dropped the "-topher" from my name, and given the common tendency
2543 to apply gender to pronouns in English, please either use nonbinary
2544 pronouns or feminine pronouns to apply to me.
2545 Other changes are happening as I wander through this space, from
2546 appearance to other things.
2547 (Probably the biggest change is finally achieving something resembling
2548 self-acceptance, however.)</p>
2549 <p>If you want to know more,
2550 <a href="https://fossandcrafts.org/episodes/30-gender-sexuality-personal-perspective.html">Morgan and I did a podcast episode</a>
2551 which explains more from my present standing, and also explains Morgan's
2552 experiences with being demisexual, which not many people know about!
2553 (Morgan has been incredible through this whole process, by the way.)</p>
2554 <p>But things may change further.
2555 Maybe a year from now those changes may be even more drastic, or maybe
2556 not.
2557 We'll see.
2558 I am wandering, and I don't know where I will land, but it won't be
2559 back to where I was.</p>
2560 <p>At any rate, I've spent much of my life not being able to stand myself
2561 for how I look and feel.
2562 For most of my life, I have not been able to look at myself in a mirror
2563 for more than a second or two due to the revulsion I felt at the person
2564 I saw staring back at me.
2565 The last few weeks have been a shift change for me in that regard...
2566 it's a very new experience to feel so happy with myself.</p>
2567 <p>I'm only at the beginning of this journey.
2568 I'd appreciate your support... people have been incredibly kind to me
2569 by and large so far but like everyone who goes through a process like this,
2570 it's very hard in those experiences where people aren't.
2571 Thank you to everyone who has been there for me so far.</p></content:encoded>

2583 </p>
2584
2585 <p><strong>MyGNUHealth</strong> 1.0 us out! The GNU Health Libre Personal Health Record is now ready for prime time!
2586 <br />
2587 </p>
2588 <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.
2589 <br />
2590 </p>
2591 <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!
2592 <br />
2593 </p>
2594 <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.
2595 <br />
2596 </p>
2597 <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.
2598 <br />
2599 </p>
2600 <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.
2601 <br />
2602 </p>
2603 <h3>What is MyGNUHealth?</h3>
2604
2605 <p>MyGNUHealth (MyGH)is a Health Personal Record application focused in <strong>privacy</strong>, that can be used in desktops and mobile devices.
2606 <br />
2607 </p>
2608 <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.
2609 <br />
2610 </p>
2611 <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.
2612 <br />
2613 </p>
2614 <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.
2615 <br />
2616 </p>
2617 <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.
2618 <br />
2619 </p>
2620 <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.
2621 <br />
2622 </p>
2623 <h3>The PinePhone and the revolution in mobile computing</h3>
2624
2625 <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.
2626 <br />
2627 </p>
2628 <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.
2629 <br />
2630 </p>
2631
2632 <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.
2633 <br />
2634 </p>
2635 <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.
2636 <br />
2637 </p>
2638 <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.
2639 <br />
2640 </p>
2641 <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.
2642 <br />
2643 </p>
2644 <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.
2645 <br />
2646 </p>
2647 <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.
2648 <br />
2649 </p>
2650 <p>Governments, institutions, and health professional need affordable technology that respects their citizens freedom. We need you to be part of this eHealth revolution.
2651 <br />
2652 </p>
2653 <p>Happy and healthy hacking!

2762 <h2>The PinePhone and the revolution in mobile computing</h2>
2763
2764
2765
2766 <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.</p>
2767
2768
2769
2770 <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 (<strong>PinePhone</strong>), and a smartwatch (<strong>PineTime</strong>), and I have adopted both. </p>

2792 <p>I wrote an article some weeks ago (“<a href="https://meanmicio.org/2021/06/04/liberating-our-mobile-computing/">Liberating our mobile computing”)</a>, where I mentioned why I have changed the Android phone to the PinePhone, and my watch to the PineTime.</p>
2793
2794
2795
2796 <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. </p>
2797
2798
2799
2800 <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 focuses on the individual and not in the corporation. That moves takes determination and commitment. There is a small price to pay, but freedom and privacy are priceless.</p>

2822 <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.</p>
2823
2824
2825
2826 <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.</p>
2827
2828
2829
2830 <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.</p>
2831
2832
2833
2834 <p>Governments, institutions, and health professional need affordable technology that respects their citizens freedom. We need you to be part of this eHealth revolution.</p>

2873 <content:encoded><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 />

2944 <h2>About GNU Parallel</h2>
2945
2946 <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.
2947 <br />
2948 </p>
2949 <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.
2950 <br />
2951 </p>
2952 <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.
2953 <br />
2954 </p>
2955 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
2956 <br />
2957 </p>
2958 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
2959 <br />
2960 </p>
2961 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
2962 <br />
2963 </p>
2964 <p> find . -name '*.jpg' |
2965 <br />
2966 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
2967 <br />
2968 </p>

3040 <h2>About GNU SQL</h2>
3041
3042 <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.
3043 <br />
3044 </p>
3045 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.

3055 <h2>About GNU Niceload</h2>
3056
3057 <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 />

3084 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
3085 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
3086 2020</a>.</p><p>Back in 2020, the substitute availability from
3087 <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> was often an issue. There seemed
3088 to be a number of contributing factors, including some parts of the
3089 architecture. Without going too much in to the details of the issues,
3090 aspects of the design of the Guix Build Coordinator were specifically
3091 meant to avoid some of these issues.</p><p>While there were some very positive results from testing back in 2020,
3092 it's taken so long to bring the substitute availability benefits to
3093 general users of Guix that <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> has
3094 <a href="https://guix.gnu.org/en/blog/2021/cuirass-10-released/">changed and improved significantly in the meantime</a>.
3095 This means that any benefits in terms of substitute availability are
3096 less significant now.</p><p>One clearer benefit of just having two independent sources of
3097 substitutes is redundancy. While the availability of
3098 <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> has been very high (in my opinion),
3099 having a second independent substitute server should mean that if
3100 there's a future issue with users accessing either source of
3101 substitutes, the disruption should be reduced.</p><p>I'm also excited about the new possibilities offered by having a
3102 second substitute server, particularly one using the Guix Build
3103 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
3104 prototyped</a>, so I'm hopeful that
3105 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> can start using
3106 <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
3107 in doing further work on how the nar and narinfo files used for
3108 substitutes are managed. There are some <a href="https://lists.gnu.org/archive/html/guix-devel/2021-02/msg00104.html">rough plans
3109 already</a> on how to address the
3110 retention of nars, and how to look at high performance mirrors.</p><p>Having two substitute servers is one step towards stronger trust
3111 policies for substitutes (<a href="https://lists.gnu.org/archive/html/guix-devel/2020-06/msg00179.html">as discussed on guix-devel</a>,
3112 where you would only use a substitute if both
3113 <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> and
3114 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> have built it exactly
3115 the same. This would help protect against the compromise of a single
3116 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
3117 substitute configuration, updating guix (via <code>guix pull</code>),
3118 reconfiguring using the updated guix, and then restarting the
3119 guix-daemon should enable substitutes from
3120 <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
3121 key for <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> manually as
3122 well.</p><p>When using Guix on a foreign distribution with the default substitute
3123 configuration, you'll need to run <code>guix pull</code> as root, then restart
3124 the guix-daemon. You'll then need to add the public key for
3125 <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
3126 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> for that matter, you'll
3127 need to adjust the substitute urls configuration for the guix-daemon
3128 to just refer to the substitute servers you want to use.</p></content:encoded>

3168 <link>https://guix.gnu.org/blog/2021/reproducible-data-processing-pipelines/</link>
3169 <content:encoded><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
3170 a workshop on reproducible software
3171 environments</a>
3172 we organized on-line. The videos are well worth watching—especially if
3173 you’re into reproducible research, and especially if you speak French or
3174 want to practice. This post, though, is more of a meta-post: it’s about
3175 how we processed these videos. “A workshop on reproducibility <em>ought to
3176 have</em> a reproducible video pipeline”, we thought. So this is what we
3177 <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/master/doc/atelier-reproductibilit%C3%A9/render-videos.scm">did</a>!</p><h1>From BigBlueButton to WebM</h1><p>Over the last year and half, perhaps you had the “opportunity” to
3178 participate in an on-line conference, or even to organize one. If so,
3179 chances are that you already know
3180 <a href="https://bigbluebutton.org/">BigBlueButton</a> (BBB), the free software
3181 video conferencing suite initially designed for on-line teaching. In a
3182 nutshell, it allows participants to chat (audio, video, and keyboard),
3183 and speakers can share their screen or a PDF slide deck. Organizers can
3184 also record the session.</p><p>BBB then creates a link to recorded sessions with a custom JavaScript
3185 player that replays everything: typed chat, audio and video (webcams),
3186 shared screens, and slide decks. This BBB replay a bit too rough though
3187 and often not the thing you’d like to publish after the conference.
3188 Instead, you’d rather do a bit of editing: adjusting the start and end
3189 time of each talk, removing live chat from what’s displayed (which
3190 allows you to remove info that personally identifies participants,
3191 too!), and so forth. Turns out this kind of post-processing is a bit of
3192 work, primarily because BBB does “the right thing” of recording each
3193 stream separately, in the most appropriate form: webcam and screen
3194 shares are recorded as separate videos, chat is recorded as text with
3195 timings, slide decks is recorded as a bunch of PNGs plus timings, and
3196 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
3197 <a href="https://github.com/plugorgau/bbb-render">bbb-render</a> tool, which can
3198 first
3199 <a href="https://github.com/plugorgau/bbb-render/blob/master/download.py">download</a>
3200 all these files and then
3201 <a href="https://github.com/plugorgau/bbb-render/blob/master/make-xges.py">assemble</a>
3202 them using the Python interface to the <a href="https://gstreamer.freedesktop.org/documentation/gst-editing-services/index.html">GStreamer Editing Services
3203 (GES)</a>.
3204 Good thing: we don’t have to figure out all these things; we “just” have
3205 to run these two scripts in an environment with the right dependencies.
3206 And guess what: we know of a great tool to control execution
3207 environments!</p><h1>A “deployment-aware Makefile”</h1><p>So we have a process that takes input files—those PNGs, videos, and XML
3208 files—and produces output files—WebM video files. As developers we
3209 immediately recognize a pattern and the timeless tool to deal with it:
3210 <a href="https://www.gnu.org/software/make"><code>make</code></a>. The web already seems to
3211 contain countless BBB post-processing makefiles (and shell scripts,
3212 too). We were going to contribute to this while we suddenly realized
3213 that we know of <em>another</em> great tool to express such processes: Guix!
3214 Bonus: while a makefile would address just the tip of the
3215 iceberg—running bbb-render—Guix can also take care of the tedious task
3216 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>.
3217 It’s still a relatively unconventional way to use Guix, but one that’s
3218 very convenient. We’re talking about videos, but really, you could use
3219 the same approach for any kind of processing graph where you’d be
3220 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
3221 file</a>
3222 that returns a <em>manifest</em>—a list of videos to “build”. You can build
3223 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
3224 traditional Scheme parlance), each of which takes input files and
3225 produces output files. More accurately, these functions returns objects
3226 that <em>describe</em> how to build their output from the input files—similar
3227 to how a <a href="https://www.gnu.org/software/make/manual/html_node/Rule-Introduction.html">makefile
3228 rule</a>
3229 describes how to build its target(s) from its prerequisite(s). (The
3230 reader familiar with functional programming may recognize a monad here,
3231 and indeed, those build descriptions can be thought of as monadic values
3232 in a hypothetical “Guix build” monad; technically though, they’re
3233 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

3309 raw data, a start and end time, and produces a <code>video.ges</code> file. There
3310 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>
3311 is a function to produce a file, <code>video.ges</code> in this case, by
3312 running the code you give it as its second argument—the <em>recipe</em>,
3313 in makefile terms.</li><li>The recipe passed to <code>computed-file</code> is a
3314 <a href="https://guix.gnu.org/manual/en/html_node/G_002dExpressions.html"><em>G-expression</em></a>
3315 (or “gexp”), introduced by this fancy <code>#~</code> (hash tilde) notation.
3316 G-expressions are a way to <em>stage</em> code, to mark it for eventual
3317 execution. Indeed, that code will only be executed if and when we
3318 run <code>guix build</code> (without <code>--dry-run</code>), and only if the result is
3319 not already in <a href="https://guix.gnu.org/manual/en/html_node/The-Store.html">the
3320 store</a>.</li><li>The gexp refers to <code>rendering-profile</code>, to <code>bbb-render</code>, to
3321 <code>bbb-data</code> and so on by <em>escaping</em> with the <code>#+</code> or <code>#$</code> syntax
3322 (they’re equivalent, unless doing cross-compilation). During
3323 build, these reference items in the store, such as
3324 <code>/gnu/store/…-bbb-render</code>, which is itself the result of “building”
3325 the origin we’ve seen above. The <code>#$output</code> reference corresponds
3326 to the build result of this <code>computed-file</code>, the complete file name
3327 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
3328 more intimidating than the toy examples you’d find in the manual, but
3329 really, pretty much everything’s there. Let’s see in more detail at
3330 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
3331 utilities</a>
3332 and tools to manipulate profiles and search path environment variables.
3333 The <code>for-each</code> call iterates over search path environment
3334 variables—<code>PATH</code>, <code>PYTHONPATH</code>, and so on—, setting them so that the
3335 <code>python</code> command is found and so that the needed Python modules are
3336 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
3337 with their dependencies (their <em>closure</em>), need to be imported in the
3338 build environment. What about <code>with-extensions</code>? Those <code>(guix …)</code>
3339 module indirectly depend on additional modules, provided by the
3340 <code>guile-gcrypt</code> package, hence this spec.</p><p>Next comes the
3341 <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>
3342 function which, as the name implies, takes a <code>.ges</code> file and produces a
3343 WebM video file by invoking <code>ges-launch-1.0</code>. The end result is a video
3344 containing the recording’s audio, the webcam and screen share (or slide
3345 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
3346 like to have an opening, showing the talk title and the speaker’s name,
3347 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
3348 produce those still images with LaTeX/Beamer, from
3349 <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/6977da4618814c790e767618da5cf9ec2cab0742/doc/atelier-reproductibilit%C3%A9/opening.tex">these</a>

3351 <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/6977da4618814c790e767618da5cf9ec2cab0742/doc/atelier-reproductibilit%C3%A9/render-videos.scm#L140-166"><code>latex-&gt;pdf</code></a>
3352 function that takes a template <code>.tex</code> file, a speaker name and
3353 title. It copies the template, replaces placeholders with the
3354 speaker name and title, and runs <code>pdflatex</code> to produce the PDF.</li><li>The
3355 <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>
3356 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>
3357 takes that JPEG and invokes <code>ffmpeg</code> to render it as WebM, with the
3358 right resolution, frame rate, and audio track.</li></ol><p>With that in place, we define a sweet and small function that produces
3359 the opening WebM file for a given talk:</p><pre><code class="language-scheme">(define (opening title speaker)
3360 (image-&gt;webm
3361 (pdf-&gt;bitmap (latex-&gt;pdf (local-file "opening.tex") "opening.pdf"

3363 "opening.jpg")
3364 "opening.webm" #:duration 5))</code></pre><p>We need one last function,

3416 with videos”, and that’s right! It’s also worth mentioning another
3417 approach: <a href="https://lang.video/">Racket’s video language</a>, which is
3418 designed to manipulate video abstractions, similar to GES but with a
3419 sweet high-level functional interface.</p><p>But look, this one’s different: it’s
3420 self-contained, it’s reproducible, and it has the right abstraction
3421 level. Self-contained is a big thing; it means you can run it and it
3422 knows what software to deploy, what environment variables to set, and so
3423 on, for each step of the pipeline. Granted, it could be simplified with
3424 appropriate high-level interfaces in Guix. But remember: the
3425 alternative is a makefile (“deployment-unaware”) completed by a <code>README</code>
3426 file giving a vague idea of the dependencies needed. The reproducible
3427 bit is pretty nice too (especially for a workshop <em>on</em> reproducibility).
3428 It also means there’s caching: videos or intermediate byproducts already
3429 in the store don’t need to be recomputed. Last, we have access to a
3430 general-purpose programming language where we can <em>build abstractions</em>,
3431 such as the <code>&lt;talk&gt;</code> data type, that makes the whole thing more pleasant
3432 to work with and more maintainable.</p><p>Hopefully that’ll inspire you to have a reproducible video pipeline for
3433 your next on-line event, or maybe that’ll inspire you to replace your
3434 old makefile and shelly habits for data processing!</p><p>High-performance computing (HPC) people might be wondering how to go
3435 from here and build “computing-resource-aware” or
3436 “storage-resource-aware” pipelines where each computing step could be
3437 submitted to the job scheduler of an HPC cluster and use distributed
3438 file systems for intermediate results rather than <code>/gnu/store</code>. If
3439 you’re one of these folks, do take a look at how the <a href="https://guixwl.org/">Guix Workflow
3440 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

3490 <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>
3491
3492
3493
3494 <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>
3495
3496
3497
3498 <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>
3499
3500
3501
3502 <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>
3503
3504
3505
3506 <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>
3507
3508
3509
3510 <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>
3511
3512
3513
3514 <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>
3515
3516
3517
3518 <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>
3519
3520
3521
3522 <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>
3523
3524
3525
3526 <p>Let’s keep building communities that foster universal health care, freedom and social medicine around the world.</p>

3827 <title>GNU Health: Liberating our mobile computing</title>
3828 <link>https://meanmicio.org/2021/06/04/liberating-our-mobile-computing/</link>
3829 <content:encoded><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>
3830
3831
3832
3833 <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>
3834
3835
3836

3838
3839
3840
3841 <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>
3842
3843
3844
3845 <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>
3846
3847
3848
3849 <h3>Facing and overcoming the social pressure</h3>
3850
3851
3852
3853 <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>
3854
3855
3856
3857 <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>
3858
3859
3860
3861 <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>
3862
3863
3864
3865 <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>
3866
3867
3868
3869 <h3>A brighter future depends on us</h3>
3870
3871
3872
3873 <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>
3874
3875
3876
3877 <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>
3878

The PineTime smartwatch as the next companion for MyGNUHealth. All these components are privacy focused, Free/Libre Software and hardware.</figcaption></figure>
3882
3883
3884
3885 <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>

3890
3891
3892
3893 <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>
3894
3895
3896
3897 <p>The future of Libre mobile computing is now, more than ever, in your hands.</p>
3898
3899
3900
3901 <p>Happy and healthy hacking.</p></content:encoded>

4002 <h2>About GNU Parallel</h2>
4003
4004 <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.
4005 <br />
4006 </p>
4007 <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.
4008 <br />
4009 </p>
4010 <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.
4011 <br />
4012 </p>
4013 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
4014 <br />
4015 </p>
4016 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
4017 <br />
4018 </p>
4019 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
4020 <br />
4021 </p>
4022 <p> find . -name '*.jpg' |
4023 <br />
4024 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
4025 <br />
4026 </p>

4098 <h2>About GNU SQL</h2>
4099
4100 <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.
4101 <br />
4102 </p>
4103 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.
4104 <br />

4113 <h2>About GNU Niceload</h2>
4114
4115 <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 />
