And also when deleting a file that's on NFS, but it's reference count is non-zero in the kernel (because at least one process has it open) you end up renaming not deleting the file.

I'd guess that any of these media is sketchy for long-term archival storage. I've got probably 30 5.25 floppies in my house, and I have a 5.25 drive and an old motherboard that can probably recognize that drive, and I've got

Would they announce record losses and financial distress? We'll see when they go public. Until then all these press releases are strategic messaging...

Zitron's claim is that much of that boost in profit for microsoft and alphabet and amazon is from only a few customers, specifically openAI and anthropic, and that those companies are buying and promising to buy lots of resources with

I have watched many of his screeds; I think he undercuts his thesis with excess bile. His core observation is that the unit economics of openAI and anthropic don't actually yield enough profit to pay off the huge debts that these two c

Sure, that's possible? It's also possible that, because the US is busy bombing Iran, Iran may be busy attacking the US infrastructure in any way possible? The US is also in a tepid war with russia, last I checked. Some "cybe

That reminds me of core memory, which is also nonvolatile and for a long time was the primary memory of many computer systems. I suspect "growing up" with a system where the computer itself is nonvolatile (turn it off, move it, tu

Just to help me out a little; you're saying "printing press and electricity" But there were printing presses before movable type, and movable type specifically allowed creation of inexpensive books and newspapers. The printi

I am planning on fiddling with using the TPM of an old dell 5820 I've got floating around my house as a budget HSM. It looks possible, on paper, if you don't poke at it too often.

And I would have put the bearing shell over a pvc pipe and used a hand drill or just spun the drill bit between my fingers, assuming it is just bearing material.

Those kids (the autopian team) specialize in generating engagement doing things that are pretty unsafe... Another example would be the dude who used a chainsaw on some lead acid batteries, for reasons. https://www.theautopian.com

DRAM is highly regular and relies on a 1T1C (one transistor, one capacitor) structure. Because those tiny capacitors naturally leak charge, the adjacent transistors must be optimized for ultra-low leakage. That requires thicker gate oxides

Cisco has trained a generation of home-lab would-be cisco engineers to dig through shady russian forums to download sketchball binaries. I think they even hide the checksums of their gated binaries, just to make sure you're never sure

I'm overall not a fan of Cisco; quite the opposite. There are lots of companies ahead of Cisco in the "pretty not so cool" these days so my ire is not as strong as it was when I was a young idealist. As far as I can tell, in

Thanks for the head's up! The Rukus Unleashed looks like the perfect replacement for my icky system. I'll put in an ebay search notification for when the R650 (and R750) for $50 each and maybe it'll ding in a couple years an

I didn't look at those; do they support running some controller thing in one of the APs to allow central management of all the nodes? Cisco's mobility express just runs on one of the APs and can fail over to another of the APs; it

Unfortunately you need to use the cisco software / firmware. The access points run linux but they're locked down like crazy with signed firmware blobs and such. That said, the cisco firmware for this specific generation of access

It is probably a combination of hitting a (low) cost and mimo; cisco makes pretty reasonable looking APs with lots of radios and decent coverage and they look like UFOs not alien spiders. But it's probably easier / cheaper to get

I have been extremely happy with cisco 3802 access points purchased on ebay for $25 each. Sure, it's only wifi5, but they're pretty solid and you can just deploy a swarm of them. And they don't look fugly. It is a tremendous

I think the "party line" is that the goal shouldn't be "1950s grid, but bigger and with more red meat!" Renewables actually cover a lot of the newer demand and can be put around where it doesn't require as much

What about running that same codebase on open source versions of mumps such as GT.M or Yottadb?

How do you think your code would do in GT.M or Yottadb? I understand both are open source (vs Cache).

Sorry; one final edit: What you're describing is "bank" where the financial organizations settle transactions using a private media ("the crypto"); but each individual is still dealing with "a bank". In &q
