I had a server (back when servers came in towers, not rack units) that would lock up hard randomly at about weekly frequency, unless there was a PS/2 mouse plugged in. We put it ziptied in a couple of unused 5.25" bays.

This server spent years after that as the distributor of Debian to European mirrors.

The cause? Some memory mapping bug in bios, we think.

@a1ba
Are those nokia switches?

@landetannien
Men är förpackningen immun mot dina argument?

@ErikUden
I've been suggesting xmpp for some time. There are small enough servers to not be a noticeable increase in size or complexity of the running stack. And you could do proper private messaging.

@GossiTheDog Two TietoEvry updates that I'm not sure has made Eenglish language news.

1: In an interview in DN, the TietoEvry spokesperson stated that they still have no idea how their systems were breached, but repeatedly insisted that they had sufficient security measures beforehand.

2: It has been discovered that in their public sector contracts they were also responsible for backups. All that data is now gone. Oh, and all of TietoEvry's logs too in that DC, which might explain 1).

Resdag idag, kanske kan återkomma med ordinarie kontorsfönster på fredag.

Dagens lunchrestaurangutsikt

@clacke There are good reason to not do long simmers of anything acidic in cast iron pots, you leech out a bit too much iron to be healthy that way IIRC.

@GossiTheDog
Regional hospital update: Supply of consumables solved, still struggling without the discharge IT system which is still down.

Especially complicated for patients that get discharged to other long term care, 8-10 phone calls per patient instead of some form entries and maybe one or two phone calls.

There is also fear, but nothing confirmed yet, that the patient records in this system might be in the wrong hands.

Det var äntligen bra skidväder, varken -30 eller +5.

@elhult Expect it to take a while. @pettter has made it to Switzerland by train a few times, I think.

@thanius
Ungefär såhär, va?
@Skruvdobb

@meraord
Jo, var lite bökigt att cykla ner på stan här i Ume

@Blender Do you want more mirrors? We do run a pretty big one over here at ACC.

@amanda
SE3 is only 2-4 times as bad on average, which is still 10% of fossil gas (400-500 g/kWh is where you get same emissions from manufacture and use somewhere between 3-10 years).
@pettter

@amanda Having recently done the numbers for servers for scientific computing, the manufacturing seems to be 1-2 tons of CO2e. For running computers in SE2, assuming the local power mix emissions (11-15 g/kWh), the manufacturing emissions totally dominates for both 5 and 10 year lifespans even when running them flat out 24/7.

Money is a different matter, where 5-7 years lifetime is more reasonable since you get 1-2 orders of magnitude more compute per kW.

@amanda
Probably, yes, and if looking just at CO2 emissions. It gets different if your electricity has a large share of fossil emissions in it though.

@pettter So if I manage to get him or Kai Greshake or someone in this field to come up for BSides Ume 2024, this might be useful for drawing a crowd?

Hey, @pettter - I saw a great presentation on exploiting LLM services. Is stuff like this something that you or some of your fellow AI researchers are interested in?

There's plenty more articles there too, this was just one of the newest and interesting ones.

Shoulder riding is the best!
