@ddlyh Oh, and adding to this, this was a 20 minute talk, so there wasn't all that much that isn't covered by text in the slides. In this community we consider the published slides to also work as notes for the audience and the institutional record of what was presented. @wim_v12e

Gave an updated talk at #HEPiX on carbon lifecycle analysis for scientific computing exploring how long you should run compute nodes when optimizing for minimizing carbon emissions.

We use real numbers from four data centers, and a couple of hypothetical cases, to explore how the local electricity generation emissions impact how sensible it is to run old hardware until it breaks.

Also tagging my co-author @wim_v12e who has done most of the model design.

@GossiTheDog If only the Chief Security Scientist and Advisory CISO at Delinea had had an opportunity to listen to that episode, maybe they would have been better off!

@ckure Much like SQL, the footgun way is the easiest and most well-documented way of doing things. "Teach better" isn't likely to start working now when it hasn't for 20+ years.

But execvp instead of exec, however that's done in your current favourite language today, is exactly how you avoid wrapping a shell, just like you suggested.

The rest is just avoiding shell for scripting as well?

@ckure The whole point being that you do not invoke a shell. At all. It is a way to avoid accidentally putting in a shell where you didn't think there was one.

@ckure Very related: This is why you always should exec a list, not a string (which gets interpreted by a shell). Same basic hygiene as parametrized SQL.

Swishade förbi denna goding i hög fart i slutet av en backe. Hade nog inte varit helt bra att cykla på den.

@linus Svetsa plast snett kan ge fosgenutslag i detektorer plus rök som gör folk illamående, och samtidigt vara ett tekniskt fel och inte en attack?

@GossiTheDog
Denying foreign actors access to UK companies secrets isn't in under economic advantage?

Ours actually has that in there (especially for govt entities and suppliers), as does (theoretically) NSA.

@GossiTheDog
One could argue that your tax money should also be spent by GCHQ to happen to look into increased CPU usage after some weird lib update in all the places where they didn't plant anything.

@shortridge
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.

Are those nokia switches?

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.

@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.
