You can’t buy the gpus individually, and even if you can on a secondary market, you can’t use them without the baseboard, and you can’t use the baseboard without a compatible chassis, and a compatible chassis is full of CPUs, system memory etc. on top of that, you need a fabric. Even if you cheap out and go RoCE over IB it’s still 400gbs hcas, optics and switches
Yea, a node in a cluster costs as much as an American house. Maybe not on its own, but to make it useful for large scale training, even under the new math of deepseek, it costs as much as a house.
Multipass is pretty clutch for trivial VMs on MacOs for sure. I use it for a bunch of ssh jump boxes running vpns to different sites. The macOS build does not support custom images (lest not without [some truly insane hacks](https://github.com/canonical/multipass/issues/1260#issuecomm...) , which doesn’t really matter for what I use it for but it is kind of a bummer. If you need something with a little more grunt but don’t want to go full blown with writing your own QEMU tooling or fussing with something like UTM or Parallels, [quickemu](https://github.com/quickemu-project/quickemu) is a really nice qemu wrapper with sane defaults that can expose a whole lot of power if you need it.
This is pretty cool, The UI is a little tough-- deleting code blocks is clunky.
its also hard to break out of the type modals
there should also be some kind on context aware help dialogue to tell you what operator/type you have active is/does
As of two years ago when i dumped fedspace, the agency i was tied to had the phones legit mdm locked down and usage was actively monitored. It sucked so hard that phone was effectively unusable, but when the site youre at makes you leave all personal electronics outside the fence, its better than nothing.
my back of the napkin math only puts this around the same stopping power as plywood of similar thickness. Sand bags work a lot better and are a hell of a lot easier and cheaper to produce
Apart from the fact that sprinkler systems are almost always 24VAC and every commercial sprinkler controller I have ever used or investigated use optocouplers/fets/triacs I don’t really have a good reason to get irritated by homebrew designs that use relays, but I do get irritated. I think the irritation comes from wanting to really learn-by-copying how to design these circuits and many hours searching for exemplars and reading datasheets left me pretty confounded (though most of this was during the great supply chain squeeze so I couldn’t find the right combos of triacs and optocouplers ins stock and the datasheets led me to believe that subbing out a non zero cross would probably be a problem, or not being able to find logic level triacs)
I think there is more to it than that— AC lets you move current over longer wires without voltage drop or having to use really thick wire. This is why Tesla triumphed over Edison. Honestly, there are a ton of applications that could benefit from low voltage AC that don’t leverage it because DC is king in on the test bench and that inertia creates the need for klunky workarounds to overcome its deficiencies in large, long series circuits.
> There's also a huge industry around certification and compliance that adds almost no value. I've never known any experienced security professional who places any value in CISSP, CEH, etc. (In fact they're often a negative indicator of competence). They're the security equivalent of a 6-week coding bootcamp. Mostly just a cash grab.
Preach. The number of times I have had to explain basic computer to a cissp is larger than I’d like to admit.
