OTOH, it'd a fun science project just to built one, for maybe a different set of kids that operate the box.

Just needs motivated teachers, if you ask me. I assume the mothbox is more of a high-school project, building one seems on that level as well.

We have a group of kids in Rhode Island building some with the library there! Part of a "Wildlives" program where the kids also learn to put camera traps around the local nature!

Def just needs motivated teachers!

If you're bilingual, it's often useful to read a wikipedia topic in more than one language, as the editorial slant may be different in different languages.

Can at least confirm for German/English.

Are the hospital chairs cheap? Genuinely asking...

Amazon appears to offer such chairs for like $200? They're probably crap though.

They're crap. And that's what you find at hospitals and airports.

That's a pretty good post-mortem report. I hope they have implemented all the proposed process changes.

There seems to be a huge difference between spin-down while NAS is up vs shutting the whole NAS down and restart. When I start my NAS, it takes a bunch of time to be back up: it seems to do a lot of checking on/ syncing off the drives and puts a fair amount of load on them (same is true for CPU as well, just look at your CPU load right after startup).

OTOH, when the NAS spins up a single disk again, I haven't notice any additional load. Presumably, the read operation just waits until the disk is ready.

> But then, how do B&W laser printer allow for tracing ?

They don't, because they don't need to. The point of the yellow dots is to prevent the printing of counterfeit currency, which itself tends to require the use of more ink colors than only black. It's probably possible to refill a "black" ink/toner cartridge with the exact shade of green (or whatever) to replicate the color of a currency note, but if it was easy to do then there'd probably be a lot more counterfeit bills floating around.

The ink/toner is also half the battle. The other half is the paper, since obviously the US Treasury doesn't use ordinary printer paper to print $20 bills. The usual trick is to take a $1 or $5 bill, bleach it (or otherwise remove the existing printing), and print a $20 bill design onto it - but that's easier said than done, due to both the ink/toner color issue mentioned above and due to the difficulty of getting the donor bill exactly aligned (and doing so again, in the exact same way, for the other side of the bill).

AFAIK, Napalm is illegal against a civilian population. IDK that it is illegal to use against military installations.

Not that I think it is necessarily a smart move on the part of Ukraine, since Russia can play this game too.

Allowable against military targets.

Did anyone here here set up a good rsyslogd configuration where the receiving syslog collector limits incoming logs to only known ddns machines ?

I think I may be able to stitch something together with periodically reconfigured packet filters, but I'd appreciate an existing solution.

Bonus points if running on freebsd.

Put a filter on syslog-ng, IIRC that runs on the BSDs

That looks good.

I'd probably prefer doing this at lower layers like pf, since I know how to reload those configs via cron, and since I want to avoid unwanted or malicious packets to even make it to the syslog code.

I was just surprised to find no recipe online, it's apparently more of a niche case than I thought. Worth documenting, probably.
