    I might have found the earliest instance of curl|bash (it predates curl by a year)

    there was apparently a FidoNet node *ASTERISK* [1] in Lithuania, which I only discovered by going through a nodelist trying to figure out the authors of a single-issue &quot;Hacker&#39;s Newspaper&quot; from 1995 [2] which had only emails and fidonet point addresses [1] https://web.archive.org/web/20141122230218/http://www.tdd.lt/slnews/asterisk/ [2] https://archive.org/download/Lauztuvas

    RE: https://frogs.lgbt/@famfo/116983446227015597 my favourite network is SUNET because in 2026 they still have good old L3 routing at every single hop and you can actually see the packet going through Sweden (e.g. to tungsten.libera.chat or umea.mirror.pkgbuild.com)

    Came across this lovely collection of old-timey network mapping software screenshots while looking for WhatsUp alternatives https://www.gambitcomm.com/site/large_nets.php

    Feels kinda wrong to run an RDP client through X11-over-LAN, but hey, it works. Performance of FreeRDP being displayed over Wi-Fi to VcxSrv on WinXP is surprisingly good (that is, much better than Firefox for example)

    nullfs/failfs patches in vfs.git are interesting, apparently a process can now fchroot(FD_FAILFS_ROOT) and become filesystem-less, without needing a preexisting /var/run/empty or anything. like it doesn&amp;#39;t even have a &amp;quot;/&amp;quot; anymore

    TP-Link&amp;#39;s &amp;quot;Easy Smart&amp;quot; aka &amp;quot;Unmanaged Pro&amp;quot; series of cheap Ethernet switches (TL-SG108E, etc) technically has VLAN support, you can configure up to 32 VIDs as tagged/untagged. But if you do so, the switch occasionally blasts its own DHCP discovers across *every single VLAN it knows about.*¹ Configured a port to have a tagged WiFi VLAN? Great, now the switch is going to pick up its management IP address from the guest subnet every couple of days. I do...

    Also I was learning about the &amp;quot;DHCP Option 82&amp;quot; support in the less-cheap switches in order to track down a device that apparently wakes up every morning at 07:00, grabs a DHCP lease, then disappears for the rest of the day. By the time I&amp;#39;m awake it&amp;#39;s already expired out of the MAC tables and everything. so yesterday I went around enabling circuit-id support on various switch ports and I *think* now I know which of the (empty during summer) offices to check

    packet loss

  • Post #4312126

    a bit disappointed that @mikrotik developers now started replying to support tickets with wholesale LLM generated messages... but at least it seems the dev (and/or the LLM) finally understood the root of the issue, so there&amp;#39;s that, I guess? - (thinking about it, I guess it&amp;#39;s all the more jarring when the LLM output is still signed by the same dev&amp;#39;s name as their own earlier messages. Like if I were to get a reply from &amp;quot;ClaudeGPT&amp;quot;, then I would just set...

    a d&#39;oh moment: In one building at work, there&#39;s this switch port that *sometimes* is up, but most of the time is down, well past the MAC table expiry, and I didn&#39;t really know where the cable goes or what it connects to, except that it&#39;s something in this floor or the floor below. today I was doing some maintenance at an office there, sat down at a &quot;shared&quot; PC and checked the switch... the unknown port was up. huh. Nobody else in the building at this time of year, com...

    accidentally misread a forum question as &quot;How do I use ffmpeg to transcode a German audio stream to English&quot;

    The OS language pack is English, the region is set to Lithuania, the keyboard layouts are EN and LT, the timezone is LT, the external IP address geolocates to LT. So of course the Windows weather widget defaults to Danish.

    this is why you don&#39;t zip tie cables to the wall I guess this specific AP hasn&#39;t been in use for a while now, I just took the photo while we were replacing similar &quot;quality&quot; cabling for other APs that are in active use; at least two other cables also had big holes in their insulation, not from zip ties but purely from spending a few years on the roof of a 9-floor building while *not* being outdoors-rated at all, I&#39;m pretty sure. (and/or birds I guess? idk)

    here&amp;#39;s another htop at 10 fps, and here&amp;#39;s some of the worst C code I&amp;#39;ve written (also I got all the raw frames off someone else&amp;#39;s Github) https://git.nullroute.lt/hacks/htopchat.git/tree/badapple

    this morning, on a day off, I get a syslog notification that my backup 4G modem isn&amp;#39;t connecting. (it&amp;#39;s at my little personal &amp;quot;lab&amp;quot; I have colocated at work.) I ssh to my syslog server to check what was happening, etc. It comes back up a minute later but I figured I&amp;#39;d scroll through logs anyway. Literally *the next minute* after the 4G connection has come back up – while I&amp;#39;m still typing a grep command – the workplace&amp;#39;s main fiber ISP go...

    @cks for what it&amp;#39;s worth, Feedly has not been able to receive any new posts since ~end of March, so now I have a cron job to update a local copy of cks.atom on my webserver and pointed Feedly to that instead

    RE: https://social.treehouse.systems/@grawity/116458888239365476 this reminded me of how someone once packaged the Atom editor on AUR, and since it had all of the dependencies vendored, they made it have a version number of 1.11.1.a1.8.6.ap1.12.7.d0.8.9.e1.4.3.f1.7.19.g3.0.7.gp5.17.1.gt1.5.3.l3.4.4.m0.158.7.o1.2.1.s3.10.1.sc0.68.3.sv0.243.0.t0.209.3-1

    I can only assume that https://www.ietf.org/archive/id/draft-meow-mrrp-00.html exists to counterbalance the IPv8 thing.

    they should invent smartcards which just speak the ssh-agent protocol over USB (I like my X.509 though, but it still seems like a cool idea)

    By the way, did you know that some of the Windows Spotlight lockscreen images (which get cached in your ~\AppData\Local) have an *extensive* history of where the PSD template has been exported.

    &amp;quot;A keyserver MUST NOT support indexing or downloading certificates by prefix.&amp;quot; [draft-gallagher-openpgp-hkp-09] hmm what if a keyserver *did* support downloading PGP certificates by fingerprint prefix, but returned each item encrypted with its own fingerprint, so the client could only decrypt updates for the certs which it already has

    it seems that Neovim 0.12 &amp;quot;fixed&amp;quot; guicursor= so that trying to disable the feature as documented only enables it harder (always forcing the cursor to block shape) as workaround I guess I no longer disable guicursor and let Nvim control it, but made the bash prompt reset it properly to &amp;quot;terminal default&amp;quot; afterwards (ESC [ 0 space q).

    in today&amp;#39;s &amp;quot;why won&amp;#39;t my loadavg drop below 1.2ish&amp;quot;, *something* (firefox, I&amp;#39;m pretty sure) is polling smartcards via pcscd every second, and that of course wakes up polkitd to do a JS policy check every second
