veltas··on EU–INC – A new pan-European legal entity
That's what "Pan-European" would imply, actually. Similar to what "Pan-American" means for the Americas.

However it is in Europe.
veltas··on The super-slow conversion of the U.S. to metric (2025)
It's worth pointing out the convenient imperial units are the ones that are hardest to get rid of. The "pints" in pubs is because a pint is about how much a drink should be, in fact I've often found drinking 500ml to be just slightly too little to drink, probably because I'm used to the pint, but "1 unit" is also just a lot easier to keep than "500 units" or "50 units".

Every list of problems I see from economists of all brands explaining why e.g. the UK has such poor economic performance and such a severe cost of living crisis mention the complexity and scale of taxation in the country first as a barrier to economic growth and cause of inflation.
veltas··on EU–INC – A new pan-European legal entity
It's not obvious to me at all, that's why I asked, precisely because of the use of "pan-European".
veltas··on EU–INC – A new pan-European legal entity
The title says "One Europe" and "Pan-European".

> This is clearly about EU and Europe

UK is in Europe.

Formation might be easy but the laws, regulations and planning required to do almost anything are extremely burdensome.
veltas··on EU–INC – A new pan-European legal entity
I think you can see from this thread that there is a lot more ambiguity when talking of "Europe", and also pushback against using "Europe" to mean "EU". It's not obvious, that's why I asked the question. I'm not stupid but just living in a different context to you, apparently, and have reasons to push back against this misuse of the word "European".

One might have said the use of the word "American" was misuse engineered by US Americans, to make themselves the "main" America. But for many reasons I think the context is very different in Europe, especially since the obvious grab by EU institutions hasn't really worked among Europeans, even EU Europeans.

EDIT: Further to that "Pan-American" is well understood to not just mean the USA, so "Pan-European" cannot possibly mean the EU only except by very poor wording choices or a very political agenda.

I don't think you know how continents work. It's a bit like saying Canada isn't "North American".

It says "Pan-European" everywhere, but would this include the UK?
veltas··on Giving university exams in the age of chatbots
> The third chatbot-using student had a very complex setup where he would use one LLM, then ask another unrelated LLM for confirmation. He had walls of text that were barely readable. When glancing at his screen, I immediately spotted a mistake (a chatbot explaining that "Sepia Search is a compass for the whole Fediverse"). I asked if he understood the problem with that specific sentence. He did not. Then I asked him questions for which I had seen the solution printed in his LLM output. He could not answer even though he had the answer on his screen.

Is it possible, and this is an interesting one to me, that this is the smartest kid in the class? I think maybe.

That guy who is playing with the latest tech, and forcing it to do the job (badly), and could care less about university or the course he's on. There's a time and a place where that guy is the one you want working for you. Maybe he's not the number 1 student, but I think there should be some room for this to be the Chaotic Neutral pick.

veltas··on 10 years of personal finances in plain text files
If you look at their personal profile they've made a lot of content with activity and collaboration outside of the main beancount repo, related to beancount. They definitely meet the criteria for 'FOSS dev' in that it's FOSS, too.
veltas··on Uninitialized garbage on ia64 can be deadly (2004)
In the SysV ABI for AMD64 the AL register is used to pass an upper bound on the number of vector registers used, is this related to what you're talking about?
veltas··on Thoughts on Go vs. Rust vs. Zig
On Linux you can turn this off. On some OS's it's off by default. Especially in embedded which is a major area of native coding. If you don't want to handle allocation failures in your app you can abort.

Also malloc can fail even with overcommit, if you accidentally enter an obviously incorrect size like -1.

veltas··on How elites could shape mass preferences as AI reduces persuasion costs
I think this is true unfortunately, and the question of how we get back to a liberal and social state has many factors: how do we get the economy working again, how do we create trustworthy institutions, avoid bloat and decay in services, etc. There are no easy answers, I think it's just hard work and it might not even be possible. People suggesting magic wands are just populists and we need only look at history to study why these kinds of suggestions don't work.
veltas··on All Sources of DirectX 12 Documentation
Yup I also enjoyed that time when they replaced everyone's usernames with their hidden emails on that blog.
veltas··on Codeberg is down
Good thing git is distributed!

I always like to move as much as possible into the repo itself, 'issues' etc in a TODO, build scripts, or however you want to achieve that, so you can at least carry on uninterrupted when the host is down.

veltas··on All Sources of DirectX 12 Documentation
Microsoft does this all the time, and it reeks of a lack of continuity or ownership internally.
veltas··on All Sources of DirectX 12 Documentation
And the red book isn't that good either.
veltas··on All Sources of DirectX 12 Documentation
I'm sure it misses stuff, but generally a 'spec' is better than a 'doc' for the reason that you need enough info to at least guess how a spec is implemented, whereas a doc can leave everything out and as long as the programmer has headers and some examples they can probably do 90% of what is needed.
veltas··on All Sources of DirectX 12 Documentation
Basically all native libraries inevitably have bad or difficult to follow documentation like this, proprietary or open source. Vulkan is the exception as it's a standard so needs to be very clear so all stakeholders can implement it correctly.

Usually I find if you're using an open source library you need the whole source checked out for reference, better than proprietary libraries where you need to pay and sign an NDA to get that access or equivalent support.

veltas··on Addressing the adding situation
> “play with C until the compiler does the right thing” is brittle

It's brittle depending on your methods. If you understand a little about optimizers and give the compiler the hints it needs to do the right things, then that should work with any modern compiler, and is more portable (and easier) than hand-optimizing in assembly straight away.

veltas··on Addressing the adding situation
I'm not them but whenever I've used it it's been for arch specific features like adding a debug breakpoint, synchronization, using system registers, etc.

Never for performance. If I wanted to hand optimise code I'd be more likely to use SIMD intrinsics, play with C until the compiler does the right thing, or write the entire function in a separate asm file for better highlighting and easier handing of state at ABI boundary rather than mid-function like the carry flags mentioned above.

veltas··on Why xor eax, eax?
Chapter 3 of volume 1, ctrl+f for "64-bit mode", has a lot of the essentials including e.g. the stuff about zeroing out the top half of the register.

veltas··on A new bridge links the math of infinity to computer science
Sorry I apologise, I didn't realise I wasn't allowed to care about countability.
veltas··on A new bridge links the math of infinity to computer science
> If infinite zooming/precision is ruled out, all real numbers can be written as fractions.

How?

> Problem is with the assumption that some numbers such as pi or sqrt(2) can have absolute and full precision.

That's the least of your problems, I couldn't even draw different sized splodges per real number.

veltas··on A new bridge links the math of infinity to computer science
Hi if you noticed, I never said anything about 'infinite zooming', instead I said I can write them all on the paper, which I can.

The zooming is finite for every fraction.

veltas··on A new bridge links the math of infinity to computer science
The fact that I can't even fit the real numbers between 0 and 1 on a single page, but I can fit every possible fraction in existence, doesn't mean anything?

I don't think this definition is that weird, for example by 'larger' I might say I can easily 'fit' all the rational numbers in the real numbers, but cannot fit the real numbers in the rational numbers.
