Hmmm, did NTT As2914 and Arelion AS1299 depeer in EU? Seemingly everything in the EU between them right now goes via the East Coast USA...

(see examples of London-London going via the US, but seemingly this is also happens FRA-FRA)

Unsure if this is a maintenance, since surely the whole of the EU would not go at once?

Maybe just a misconfig or interesting localpref? Surely that would not happen on both ends though...

You know, some are saying that AI will one day get free will, but they have been overlooking ceph all this time!

The average ceph installation seems to have way too much free will and has no problem in automatically doing things that either block or generate a lot of IOPS at seemingly the worst possible time

closing all my jira tickets as “by design, won’t fix” because the purpose of a system is what it does

The debian java/JRE/JDK situation seems insane.

bookworm (stable) is shipping JRE 17, lots of applications require at least 21, Trixie (next stable) is shipping JRE 21, the the current openJDK JRE version is 23

Most of the time if you search for the errors caused by out of date JRE's you get "just install Oracle JDK" with instructions, but as far as I can squint that comes with some licencing payment obligation. All of this feels like putting your head into a alligators mouth!

Took apart a DWDM XFP optic left over from the 140km TOSLINK stuff, A lovely person sent a load over that they no longer needed and they were part of my back up plan if more optics didn't work

Anyway it seems like they would not have worked anyway because the chip is a
GN2010EA that has CDR (my enemy)

The Receiver/Transmitter Optical Sub Assembly (ROSA/TOSA) may be useful for future fun though, Especially since the TOSA seems to have the DWDM Channel written on it, implying that it's statically tuned for that wavelength...

Fascinating. I accidentally collided the chassis door with the motherboard on this machine I am working on, and dmesg complained about a unsolicited IRQ!

[  149.409381] irq 16: nobody cared (try booting with the "irqpoll" option)

I wonder what actually happened here on the electrical level!

holy moly this is a lot of words

This extortion spam email's attempt at evading spam detecting by using homoglyphs is hilarious, mostly the

"broωsing" -> "oωo"

but also the rather... lol language?

Incredible spam 10/10, not even upset it landed in my inbox

The PDU, it screams, and honestly... Me too buddy

Unsure how to feel about @NetworkManager being the Linux fedi's version of the Wendy's twitter account

Ouch! Hetzner will be wholesale replacing the motherboards of 3 different SKUs over all of their locations, That's a rough decision to have to come to

huge hugops to Hetzner, that's a immense amount of work to commit to

Is it too much to ask for a 2024 version of the HP Gen 8 Microserver? It honestly feels like HPE accidentally made a machine so good it cannibalised so much of their other markets that they vowed to never make a microserver that nice ever again

Another great NetLdn meetup last night! Including a talk about mitigating "acts of god" as a WISP (hint, wind makes your radios fly away, and water makes everything sad)

The next NetLdn is on Feb 13th and already has a full line up! If you are around say come say hi!

@benjojo

We do not know why we are here. We do not know who built the underground. We do not know why everyone on the underground is as they are.

Did another hidden London tour! This time Baker Street.

Love the post apocalyptic vibes the behind the scenes bits of TFL always have

How could you not love these incredibly easy to understand works of art

Huh, first ever case of seeing a "verified" RCS message like this... from HMRC?!

What "verified by BT" actually means in this context is a bit of a mystery, but the whole thing seems a tad jank, this is the first non-spam RCS message I've gotten so far

New post!

After a over a year of slowly messing around and calling favors, I have to get a TOSLINK (yes, the HiFi audio standard) link to go 14600 times further than the spec sheets suggests!

And learned a whole load of how modern optical stuff works along the way!

Building Ultra Long Range TOSLINK

Visited a nuclear power plant today (Sizewell B)! Sadly no photos allowed, but a remarkably great tour given the average tour group was clearly schools or various non-ish technical groups, ours were all infra/power nerds and I was amazed how well they could answer all of the meaty questions!

This may not look like it but this is what peak oven element looks like

Happy new years to the 2026 CT logs that are now slowly populating with 2025 1 year duration X.509 certs!

Even bigger ups to the certs that issued bang on UTC new years!

I love this prompt from the angle that it's such a low cost airline thing to do.

Surely it is not worth prompting for 3p riiiight??

Need a dedicated button on google flights for "actually London airports" that sets this

@benjojo why yes, I just happen to have this lying around

Does anybody know of any academic literature around the medium-term (10 hours a day for 5 days) exposure to smoke machines?

The best thing I can find is literature around accumulated exposure around vapes, and this isn't really a fair comparison as people typically don't vape via their noses

I'm mostly asking because it turns out that I get a very slow running nosebleed around these things, it's not really an issue but I know other friends where who get much bigger problems

(For what it's worth, I realise it's not just a #38c3 smoke machine thing, I've never managed to figure out what causes these very slow nose bleeds until just the last few days, but the last 10 years of these now make sense with this context)

pfft, welp, I was not expecting my laptop stickers to be that visible on the video! I guess the audience angle vs the c3VOC angle is quite different lol

See you next year #38c3

hot damn the linux-firmware package is 498 MB, the chips thinking way too much these days

Missing the vibe with the lasers in Hall H #38c3

And some more pictures from #38C3

Happy to see that our sfp-experimenter boards were put to some good use by @benjojo in his #38C3 talk on doing (among other things) TOSLINK over SFP transceivers https://media.ccc.de/v/38c3-going-long-sending-weird-signals-over-long-haul-optical-networks

I get the impression that the LTE/NR roaming story is worse (and getting wrose) than it's former 2G/UMTS counterparts. This SMS from my carrier when I got back to the UK does not help this impression

me too, bye #38c3

Good night yolocolo #38c3

#38c3, awake, but at what cost

@c3noc feels like you hit some wifi client ceiling ?

another day, another time I have been caught by the auto-CW behavior of honk where any two letters and a : will turn into a content warning title

Me: hello German ATM, I would like 100 EUR?

ATM: Would you like that in a variety of notes?

Me: Yes!

Proceeds to supply 1x100eur note

Well, my apologies to the bar as I try and pay for a 2 EUR drink with 100 euro note

Merry Xmas, and hello from the kitten that is a guest this year!

See some of you at #38c3 soon!

You certainly wont regret having a emergency ipset of 3.5M entries:

I'm sure that every packet that needs to this ipset is like when something drives into a concrete wall

aww yeah, it's that week again

adding /* Ansible managed */ to the top of my my config files I don't want anyone to touch as a psyop.

It's not like I use Ansible, but that same thing did just trick me on another system into searching for a Ansible that didnt exist, so well done past operator

Is anyone keeping a high score board for sizes of GDPR polycules of various sites?
