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
packet loss
TP-Link's "Easy Smart" aka "Unmanaged Pro" 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 don't know who thought this would be a good feature.
¹ (Or maybe it chooses at random? Or maybe it's just not initializing the buffer and using whichever VID it saw in the most recent packet? Or maybe it's only doing that in the non-VLAN mode, the opposite of what I was assuming? Fuck knows.)
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't even have a "/" anymore
accidentally misread a forum question as "How do I use ffmpeg to transcode a German audio stream to English"

Sixteen Win11 computers in a single room, all freshly installed from the same USB stick, with exactly the same regional settings and everything, are showing at least 5 different weathers in three or four different languages, *none* of which is Lithuanian. How do you fuck it up this bad o7
(and if you click to expand the widgets pane, it doesn't actually have a weather widget to change the city in. Literally it's not there and it's not an option for adding a widget either)
anyway, just turned it off via GPO
a bit disappointed that @mikrotik@mikrotik.social 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's that, I guess?
-
(thinking about it, I guess it's all the more jarring when the LLM output is still signed by the same dev's name as their own earlier messages. Like if I were to get a reply from "ClaudeGPT", then I would just set my expectations accordingly. But now the reply is from the same $PERSON_NAME as the 3 earlier messages, yet the text is *clearly* not written by them, and that's just bleh.)
a d'oh moment:
In one building at work, there's this switch port that *sometimes* is up, but most of the time is down, well past the MAC table expiry, and I didn't really know where the cable goes or what it connects to, except that it's something in this floor or the floor below.
today I was doing some maintenance at an office there, sat down at a "shared" PC and checked the switch... the unknown port was up. huh. Nobody else in the building at this time of year, computers asleep or off, but somehow port 12 happens to be up at just the right time when I'm poking at the switch
so I dump the MAC table of the switch, it *finally* has one entry for port 12. I search for the MAC address in the DHCP server, etc...
...the mystery port turns out to be connected to literally the PC that I was sitting at.
[it's a "shared" workstation and a very sporadically used one at that, so most of the time it is powered off...]

(also this is a freshly installed system and in theory the AD GPO should have turned it off, or at least turned off the whole "open on hover" mess)
I'm readingskimming through the final report on the last year's Spain grid collapse and huh that's a *lot* of graphs and math, and I didn't know they keep "oscilloscopic records" at like 400 Hz of Every Single Thing

this is why you don't zip tie cables to the wall I guess
this specific AP hasn't been in use for a while now, I just took the photo while we were replacing similar "quality" 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'm pretty sure. (and/or birds I guess? idk)

@Nine it's an external Internet-Draft that someone submitted to IETF the day before this one (literally anyone can submit drafts to IETF as independent track), its main premise being that IPv6 is too different and incompatible to be adopted and therefore starting from scratch with "IPv4 with longer addresses" (and new routing mechanics) is the way to go
not the first such proposal of its kind, and it's fun thinking about alternative ways IPng could've gone, but this particular one seems to have been both LLM-generated itself and very quickly picked up by LLM-generated tech news sites as a big 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)
reminds me of how the Bitcoin software in the early days used to find peers through joining a channel on [old] freenode...

Discord keeps dying mid-raid so we're trying out the built-in voice chat in WoW and it feels like we're dusting off a feature nobody has used in decades
I mean it works quite well (aside from the UI being five kinds of glitchy) but kinda has the vibe of going back to Win98 NetMeeting
@cks@mastodon.social for what it'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
alright, time for rdo -S "sysctl kernel.unprivileged_userns_clone=0; rm -v $(modinfo -n rxrpc)"

this morning, on a day off, I get a syslog notification that my backup 4G modem isn't connecting. (it's at my little personal "lab" 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'd scroll through logs anyway.
Literally *the next minute* after the 4G connection has come back up – while I'm still typing a grep command – the workplace's main fiber ISP goes down and 4G becomes my only remaining connection ;_;
I mean it's probably a coincidence, but.

"A keyserver MUST NOT support indexing or downloading certificates by prefix." [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

my completely normal workflow:
-
trying to pick a good wallpaper for my WinXP laptop, as one does
-
browsing my homedir SMB share in XnView
-
'hmm, many of them still have XMP/IPTC/EXIF data', but XnView only shows EXIF, not XMP
-
double-click the .bat file on my desktop that rsh's to my home server and starts Xterm through the network
-
exiftool in the xterm shows a lot more details
-
:o
-
hit Ctrl-Shift-P to have SnagIt screenshot the xterm to the SMB share
-
Syncthing on home server picks up the screenshot in ~/Dropbox and syncs to the Microserver at work
-
too lazy to pacaur -y toot, so ssh to the server at work because I already have toot installed there
-
run chafa to display the screenshot via SIXEL to make sure it's the right one
-
toot post -m snag0012.png -d "alt text goes here" <<< "witty text goes here"

@famfo sometimes I catch myself being defensively verbose (when posting on SO/StackExch. in particular), like "this is an important thing I want to drive home and if you just skim the post and miss the first time it was mentioned maybe the second time will work"
(I don't like overusing bold or like a bunch of others tend to)
I'm curious how communication happens between grid operators during a blackout. I guess cell phone towers (and the associated datacenters) keep running for a few hours? Not days?
(I've heard they run fiber along/inside of the transmission lines but not what exactly they use it for)

@domi before I forget completely 1) how do you arrange planned downtime when other users are logged in; like reboots-for-kernel-upgrades stuff? do you just wall <<< "reboot incoming, hold on to your tmuxes" or do you have a monthly schedule?
(like you have some disdain for single-user selfhosting but one reason that keeps me from actively going out and Offering Services on my own systems is that I'd have no place to tinker with things anymore and get into situations where something breaks until reboot, or a security fix needs a reboot, etc. (another reason being that all my machines are kinda /old/ lol))
2) already forgot what else I was going to ask I think it was about putting literally everything on one server vs multiple lower spec servers
it seems that Neovim 0.12 "fixed" 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 "terminal default" afterwards (ESC [ 0 space q).
Also I was learning about the "DHCP Option 82" 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'm awake it'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

@moses_izumi@fe.disroot.org @domi@donotsta.re it's just deciseconds, I think. (the video is encoded at 30 fps, RealProducer's defaults are 15 fps and 30 fps depending on profile)
tbh I have never used RealPlayer for *actual* streaming video (which seems to have been its main focus); by the time I encountered a few standalone .rm's it was already more common to have K-Lite as a RealPlayer replacement.
still, I just like its very Win95/98 UI. would be neat to have some of those "channels" still working.

@andrewg@mastodon.ie well, if they request e.g. a 16-bit prefix, they can't realistically bruteforce the remaining 144 bits (for every single of the retrieved keys) to determine valid fingerprints... they can hold on to the data, but it is useless until the fingerprint is published elsewhere (at which point it's just as easy to fetch the individual certificate by fingerprint)
(I'd expect the server to refuse prefixes past some maximum length, like 20 or 32 bits, where it would stop being "privacy preserving" due to matching too few keys... but imo even with long prefixes of e.g. (x-64) bits it would be cheaper to find some other way of enumerating fingerprints (or really, scraping emails))
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 "Hacker's Newspaper" from 1995 [2] which had only emails and fidonet point addresses

@ariadne do you have an opinion on SCION by the way
like the whole OAuth thing in IPv8 reminds me a little bit of SCION having the strict core/non-core AS hierarchy, in the way that it's also pushing more top-down control
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)
