@GossiTheDog It was a lot easier for the IT folk in The Co-op to make that call to pull the plug after they'd just seen what happened to M&S!

@jmorris wave guide of some type?

I do have a bunch of HV capacitors of uncertain vintage if anyone in the UK has a fun use for them.

@scribe @ParadeGrotesque (Which if you think that giving 4 answers and referencing @ParadeGrotesque 's post is cheating, then I'd point out I'm mostly a programmer, so can use recursion and often make fence-post-errors)

@scribe
1. Network debugging
2. Basics of a few common clouds
3. All the things @ParadeGrotesque said
4. Screaming into the void.

Other #mutt users - how do you deal with long URLs received? - like in the 'confirm your address' type of mails from companies.
I tend to run mutt under an ssh rather than on my desktop, sometimes piping a mail into w3m or similar and then if I needed a URL locally I'd copy/paste - but now the embedded URLs are *HUGE* - many hundreds of characters.
Ideas?

@neil @revk I think that means @revk's front door is backdoored.

@revk @neil My reading of the Spanish slides via translation is that it's not a remote backdoor - it's a set of undocumented commands that let you write/read the firmware. Meh.

@dick_turpin Go and tell the boss you're going to go out to the Health Spa! Carefully or he might faint.

@pro what's Narch - one I've not heard of.

@pro The ARMs didn't have any (I'm not sure if the current ones do).

@pro I bet it was true of most similar generation RISCs like MIPS; Alpha (and ia64???) had 'PAL code' but that is closer to a modified machine code than traditional 'horizontal' microcode. I suspect most have it for FP stuff even on RISC, but integer probably doesn't.

@corbet I'm trying to think of the AI training that would be using compromised hosts for scraping; I thought for training you had to do the training part on one or a small number of tightly coupled hosts; so then what is it?

@codewiz Drilling a hole I think is a good way to mark/stop the corners of the cut; else get a file!

@codewiz I think the other reason is it's used for making bombs.

@codewiz If you're going to throw the component anyway, you can trim it off on both sides before trying to remove the leg, that normally makes it easier to desolder.
Have you got a pointer to the cheap pump iron? The ones I've seen are silly money.

@inthehands Sounds like chip design/CAD software. I remember in a startup my boss installing a new Cadence component and hitting a problem with it, and getting the response from support that they hadn't had anyone get that far before.

#kde karp sounds relaly nice; GUI for rearranging and fiddling with PDFs:

@cks You can do crash dumps on Linux; they set up a kexec into a small setup held in reserved RAM and it does the dump; you then use 'crash' to poke at the dump file later. The RHEL etc set normally do that by default.
(But I'll agree filesystems panicing is generally bad)

@codewiz Youmight try one of the magnifying visa things; having the binocular vision is handy.
