veltas··on Social media bans and digital curfews to be trialled on UK teenagers
As a British teen I concerned my parents a lot with my computer usage, with all they had heard about the dangers of over use. But for me that was an outlet in a pretty miserable childhood and turned into my career, I was programming and learning how stuff worked. I don't envy the kids that found an outlet doing something productive only to have a nanny state eventually rip it away from them.

veltas··on Epoch confirms GPT5.4 Pro solved a frontier math open problem
It's not 'magic' though but previously LLMs have performed very badly on longer multiplication, 'insight' is the wrong word but I'm saying maybe they're not wildly better at this calculation... maybe they are just optimising these well known jagged edges.
veltas··on Epoch confirms GPT5.4 Pro solved a frontier math open problem
Do we know for a fact that LLMs aren't now configured to pass simple arithmetic like this in a simpler calculator, to add illusion of actual insight?

The overwhelming majority of UNIX-like software is available in the package managers right now for major BSDs.
veltas··on “This is not the computer for you”
I didn't grow up in a 3rd world country but had the same experience, bar running games I don't own. Not everyone in the west had parents that wanted to just spend thousands on hardware that seemed to be obsolete next year, or any means of making that money. And I've never stopped using sub-par hardware, to this day I enjoy squeezing every drop of performance from cheap pre-owned stuff.

Just a point that the constexpr/const use in that C++ code makes no difference to output, and is just noise really.

Dude that's not a 'puddle' as the article claims, that's a body of water that it's not even visually obvious whether it's safe to drive through. Maybe I'm a bad driver but I'd hesitate to drive through that in a small car either.

Not just similar, it's exactly the same issue caused by exactly the same kind of change, and is probably hard to fix for almost exactly the same behind-the-scenes complexity on Windows.
veltas··on RISC-V Vector Primer
Problem RISC-V has is there's no middle-ground.

The specification for an architecture is meant to be useful to anyone writing assembly, not just to people implementing the spec. Case in point x86 manuals aren't meant for Intel, they're meant for Intel's customers.

There is a lot of cope re the fact RISC-V's spec is particularly hard to use for writing assembly or understanding the software model.

If the spec isn't a 'manual' then where's the manual? If there's just no manual then that's a deficiency. If we only have 'tutorial's that's bad as well, a manual is a good reference for an experienced user, and approachable to a slightly aware beginner (or a fresh beginner with experience in other arch's); a tutorial is too verbose to be useful as a regular reference.

Either the spec should have read (and still could read) more like a useful manual, or a useful manual needs to be provided.

Yeah the other day in calc.exe I pressed F7 in programmer mode to change to octal (F5 to F8 select Hex, Dec, Oct, Bin), and instead it asked if I was sure I wanted to enable caret browsing.

veltas··on Tiny C Compiler
To me it just seems like they are prejudiced against Brits or something.

I don't buy their statement about legal concerns given it's as vague as GDPR, and equally as inapplicable to a www git, and yet they've not banned the EU.

It's quite toxic to ban a whole country from your project without good reason. I've seen people break more of a sweat worrying about whether Russia should be banned from open source projects than the UK. It's not unfortunately unexpected, people love being ignorant about the UK.

veltas··on SectorC: A C Compiler in 512 bytes (2023)
This is very nice. I'm currently writing a minimalist C compiler although my goal isn't fitting in a boot sector, it's more targeted at 8-bit systems with a lot more room than that.

This is a great demonstration of how simple the bare bones of C are, which I think is one reason I and many others find it so appealing despite how Spartan it is. C really evolved from B which was a demake of Fortran, if Ken Thompson is to be trusted.

veltas··on Apple I Advertisement (1976)
> Apple bundled BASIC for free because Woz wrote it himself, they had no software costs to recoup.

But in respect of Gates' letter, Woz didn't write that BASIC for free, he wrote it to enable his hardware platform and the time spent writing it is a cost/investment in the platform. Gates was just trying to make a business writing software without the hardware.

Also Apple are the ones that made Gates' sentiments a reality with the precedent set in Apple v Franklin (1983) defending the copyright of their BIOS software.

veltas··on Waymo robotaxi hits a child near an elementary school in Santa Monica
The main concern I've got here is the gap between a human's intuition to prevent this kind of situation vs an algorithm. I'm interested to learn more about Waymo's logic here too and I'm hoping my concerns are addressed in their algorithm, it wouldn't be impossible and it would make their vehicles safer. I can believe in a scenario where these vehicles are safer than 99% of humans, and I don't think we're there yet, but I'm open to being proved wrong. The main point I'm making with my speculation and hypotheticals is that the safety of the kid that walked out doesn't start with them walking out, the safety starts before that, and it's worth comparing with experienced drivers with good track records and asking them what sort of things are going through their head as they drive. They're more perceptive than some people might expect, and I would guess more perceptive than the algorithm currently is.

> Technically, in CA, the speed limit in school zones are 25 mph

Legally a speed limit is a 'limit' on speed, not a suggested or safe speed. So it's never valid to argue legally that you were driving under the limit, the standard is that you slow down or give more room for places like a school drop-off while kids are being dropped off or picked up.

veltas··on Waymo robotaxi hits a child near an elementary school in Santa Monica
Absolutely, I can tell you right now that many human drivers are probably safer than the Waymo, because they would have slowed down even more and/or stayed further from the parked cars outside a school; they might have even seen the kid earlier in e.g. a reflection than the Waymo could see.
