a good writeup on how Free Radical survived and adapted to a burst of new Mastodon users.the specific technical bit of interest is adapting #sidekiq to handle more traffic, by throwing a Raspberry Pi 4 (!) at the problem.the writeup athttps://blog.freeradical.zone/post/surviving-thriving-through-2022-11-05-meltdown/writeup by @tek thanks @lupyuen for bringing this to my attention#mastoadmin

@tek @lupyuen Four Arm cores, plenty fast. Lots and lots of people dealing with (or maybe struggling with) Sidekiq these days, always good to hear the different ways that people deal with queues.

I'm working on a blog post about the technical bits of Mastodon servers scaling up - mostly just an overview of what people have done at various scales.So far examples from:@dzombak @rey @M0YNG@tek @Taniwha @ariadne At small scale, the answer seems to be "spend more money on VPS"; at a larger scale, "tune @sidekiq ". I have a blog post from @tek linked so far. If you have done a writeup on what you have done I'm happy to share it.trying to catch a moment in time.

internet in the airplane results from 1992, when @peterhoneyman was able to bring up a SLIP dialup connection at 300 baud on a GTE Airfone with 60+ second ping times (and no useful communications other than ping).https://spaf.cerias.purdue.edu/~spaf/Yucks/V2/msg00056.html"in summary, it was something of an accomplishment to get slip running and packets bouncing from 30,000 feet, but a limited success at best."cc @renice for comparison

An #obsidian and #dataview query I am finding useful for "wiki gardening", on the page "Ancient pages"```dataviewLIST file.mtimeSORT file.mtime ASCENDINGLIMIT 10```This surfaces pages in your word hoard that have not been edited for the longest time, so that you can decide to bring them up to date or delete them as appropriate.cc @Vaguery cc @obsidianmd #obsidianmd

Watching the #corejs issue.The developer of an absurdly popular open-source project which helps Javascript developers deal with old, broken, or out-of-date browsers has had it with open source. He is considering to abandon the project or change the license. https://github.com/zloirock/core-js/blob/master/docs/2023-02-14-so-whats-next.md#polyfill

@thomasfuchs This 1990 FAQ from Epson says the drive worked in an Epson Equity series computer, with a "non-standard FDD interface".https://files.support.epson.com/pdf/psb/psb.s-0060a.pdfYou might hunt for "Epson Equity" docs. The few I have read suggest that Epson sourced some parts that were nearly but not quite compatible with standard interfaces of the time, so there may be some goofball surprises waiting.

@osi ironically, most "AI" engines have been trained on data sets that care little about compliance; see e.g. the Getty Images v Stability AI complainthttps://copyrightlately.com/pdfviewer/getty-images-v-stability-ai-complaint/?auto_viewer=true#page=&zoom=auto&pagemode=nonealleging theft of 12 million images

I don't actually believe that privacy-preserving telemetry is even a thing that can be real. Telemetry is designed to leak information about what's happening on a system, and by doing that you inevitably leak bits of privacy-adjacent material, and if you accumulate enough bits you get reidentification of previously "anonymous" information.My favorite old-school reading on this is the 33 Bits blog https://33bits.wordpress.com from Arvind Narayanan.

@ignaloidas so noted, but the opt-in telemetry (quite simply, upload your dmesg files) described here https://vielmetti.typepad.com/logbook/2023/07/privacy-preserving-telemetry-isnt-real.htmland https://dmesgd.nycbug.org/index.cgi?do=indexis so much simpler and gives you 99% of the results you are seeking at 1% of the complexity.

@CoolerPseudonym email in the uucp era certainly was federated, and bang-path addressing meant that you had to either understand a network of hyperlinks or (later) to pay someone to do that for you. the network of systems admins that kept it all together (sometimes by hiding long-distance phone charges).you had to find a provider first, and then you had to hope they were within local calling range and that they didn't have endless busy signals.

@CoolerPseudonym my first email address had a MULTICS and a MAILNET and an ARPA in it, and a couple of % signs sprinkled around for maximum confusion, and it took a number of years of hard work and mailer science to simplify that into a .edu address that you would recognize today.

@foone There's a little bit of code herehttps://github.com/raspberrypisig/pizero-usb-hid-keyboardthat uses a Pi Zero to emulate a keyboard and has examples from the command line. So the host half of this at least has been successfully done at least once.

@foone FORTRAN is OK (John Backus)MAD (Michigan Algorithm Decoder) would work too, it's a 1959-era ALGOL variant. (Error pages printed out with "What, me worry?") But ALGOL-58 was from Switzerland.
