Can you make massive bets if there's no one to take the other side of the bet? In a prediction market that allowed insiders, if you don't have insider knowledge you shouldn't bet very much because you're probably going

Which is a good thing. They should be teaching the cornerstone principles, not offering vocational courses.

The Melania documentary is an important artifact that historians will be talking about for decades, although not in the way those involved anticipated.

I use openrgb to turn off all the RGB crap on my desktop machine. Unfortunately you have to leave openrgb running and it takes a constant 0.5% of CPU. I wish there was a "norgb" program that would simply turn off RGB everywhere

Dear Sony, please start making the MDR-XB450 again. Lovely wired headphones that for some inexplicable reason Sony discontinued a few years ago.

passt (the network stack that you might be using if you're running qemu, or podman containers) also has no dynamic memory allocations. I always thought it's quite an interesting achievement. https://blog.vmsplice.net&

UK population density (people/sq km) is 289 and Switzerland's is 228, so not very different. Plus Switzerland is fully connected, there are no remote islands. [1] https://www.worldometers.info/world-population&#x2

I don't understand the reason for electronic voting. The UK manages to tally up paper votes overnight, even from far-flung Scottish islands. Electronic voting is literally solving a problem that nobody has.

FWIW I wrote this article a while back all about RISC-V extensions and how they work at a low level: https://research.redhat.com/blog/article/risc-v-extensions-w... page 22 in this PDF: https://research

Unfortunately they found a bug and had to redesign the boards. I've had one of these on pre-order since last year. Latest is I think they're intending to ship them next month (April). The SpacemiT K3 ( https://www.spac

The Milk-V Titan ( https://milkv.io/titan ) can take up to 64GB which is fine considering the number of cores and the cost of RAM. If you needed and could afford more RAM you'd be better off distributing the work across

Neither x86-64 nor RISC-V is implemented by running each single instruction. They both recognize patterns in the code and translate those into micro-ops. On high performance chips like Rivos's (now Meta's) I doubt there'd b

Not sure why you're being downvoted, this is very much my experience. When it matters (like, customer data is on the line) vibecoded projects are not just hilariously bad, but put you in legal danger. We've so far found that Clau

This is the reason behind the profiles like RVA23 which include bitmanip, vector and a large number of other extensions. Real chips coming very soon will all be RVA23.

The 2 designs I'm thinking of are (tiresomely) under NDA, although I'm sure others will be able to say what they are. Last November I had a sample of one of them in my hand and played with the silicon at their labs, running a bun

RISC-V doesn't have the pitfalls of Sparc (register windows, branch delay slots), largely because we learned from that. It's in fact a very "boring" architecture. There's no one that expects it'll be hard to

Marcin is working with us on RISC-V enablement for Fedora and RHEL, he's well aware of the problem with current implementations. We're hopeful that this'll be pretty much resolved by the end of the year.

It's more nuanced than that. This article is about the US (a worse polluter than Ireland), but it shows only about a small difference because of offshoring emissions: https://www.noahpinion.blog/p/no-the-us-didnt-

I used MINIX on 8086 which was similar and it definitely was not efficient. It had to make a copy of the whole address space on fork. It was the introduction of paging and copy-on-write that made fork efficient.
