Spinrite ftw

I’m using apcupsd for my server, even wrote a little script to pull wattage off the apc and report it in byobu’s status bar. Anytime I ssh into my server I can see current wattage (usually about 55W for 4 spinning rust drives, 2 SSDs plus the router).

I saw the omnia for €339, vs this router…

What would you suggest?

Luxottica. I’ve visited their HQ in soCal, people aren’t having fun and coming up with wacky designs anymore.

Sure, glad to help. We need every bit of help against the powers that be at this point.

calyxOS has it too.

Brush yo teeth bruh.

Just kidding 🤪

All of what you’re saying seems correct. I think this is more of a meta discussion, on how (in this case) retries, even with exponential back off, aren’t a solution by themselves when you look at the system overall. There are interesting hidden caveats to any common solutions, this is one I personally wasn’t aware of.

Practically, adding a timeout budget so that the clients themselves just error out (forcing a manual refresh) sorta accomplishes the same as what you’re positing.

Hmm… I’d say that was an obvious example to cause the situation, the real point was exposing the more subtle problems with feedback loops.

What happens if the server in question was at 80% capacity, and due to hardware faults, that leads to 100% utilization? Can you reconfigure your services if there’s a cascading overload through enough of the system without actually adding to the system load? What do you do about the fact that these loops gets ever more powerful and sudden the larger the system?

The author seemed to be suggesting that we carefully consider how to avoid open feedback loops, and build stability in. This article clued me in that stability problems can be borne from “industry standard” advice if you don’t carefully think about it.

Very interesting, thanks for this article. It’s funny how I notice ever more repetition of phenomena through different branches of engineering; metastable failure caused by feedback loops is possible both in mechanical and electrical engineering. Named differently though, resonance and ringing, respectively.

Good article, thanks

A projector.

That’s how I feel about it as well. Better to upgrade the safe than to add warning posters.

I kind of expect it to be required, SCADA has had plenty of ancestry. But you’d expect the NSA to have been consulted on how to prevent interaction with the general public…

I know, right? Like how the hell do you get worried from such a silly movie… Unless he knew the us military defense systems were in fact that weak, against people and their telephones.

Nah, Reagan was just a wuss.

Dude, this whole website is fucking amazing, one of the phones has a DLP projector built in??? I love it, if only these could run CalyxOS.

I agree. We collectively overconsume, where are the manufacturers with pride in building quality devices that just work?

I’m a hardware engineer, I’d be embarrassed to release some of the shit I’ve seen onto the market for public consumption.

The rules are simple: solid state where you can, robust enclosures that can withstand common cleaners & IV exposure, geometry that makes it difficult for those cleaning fluids to get into the electronics. That’s it, you’ve got most people covered with a reliable device to interact with daily. Pinch pennies on the RGB LEDs, not the housing!
