My first design using a 555 timer 😅
Can anyone figure out what it does ?

@npub1k2p…khdz I'm not overly worried about it, but it still seemed fairly high to me.
I'd have to boot my old system and check, but I though I was getting much much less on my previous system.

Anyone using btrfs on ssd would mind looking at `smartctl -a` and tell be how much write ( Data Units Written ) they see along with disk age and how much is used on it to give the number some perspective ?
I'm seeing 12TB writes on a ~ 1.5y old drive that only has ~ 250G of data, most of it was copied over at install time and I find that pretty large.
Looking at /sys/block/x/stat , over some time and extrapolating, that number seem plausible so they were issued by the OS.

Is there some website that list all candidates / party for your country along with their advertised program and also the previous offices they held and their votes on previous decisions (i.e. what they actually did in the past) and stuff like that ?
Like I'd like my vote to be informed and not random but I don't have a year to dedicate to research every candidate in depth ...

@npub1tx3…kxnn One does all the work and the others stay out of their way.

@npub1tx3…kxnn
One common thing for a DDOS being very effective is to come from a lot of sources with nothing in common (like lots of compromised devices across the world). If all requests were coming from IP ranges assigned to cloudflare, it'd be pretty easy to block ...
But if you have any evidence that they initiate the DDOS, it would certainly be racket. But if they are not the source, that's a pretty big/obvious difference ...

@npub1tx3…kxnn No that's the space for a R&S FSQ8 Spectrum Analyzer (old/used and thus chonky). On top of it will go a pair of Agilent E4433B Signal generators.
The scope I have is a Agilent 3000X, much more modern and thus compact and will be in the middle narrow shelf.
(I only modeled the FSQ8 because it's the biggest one and I know the other would fit without me having to model them 😅 )
