okay so i started thinking about big pext and it's a little tricky.

so let's define the problem. if you have hardware pext support, you will get 64 and 32 bit versions. which are great if those are what you want and a bit shift if you want an arbitrary size. so we want pext for arbitrary size buffers, or big pext.

say we have an array of 64 bit integers, we can do most of the work with 64 bit pexts. this will select all of the relevant bits, but it will organise them all in their original 64 bit chunks. intuitively with some shifting about, we can fix this, but that shifting about is pretty annoying.

but it can get more annoying! i have already got high throughput versions of array pext. i would of course want it to keep up with that so it's really only slightly slower for the same amount of data.

i think it's doable, but it's not immediately obvious how to do all the shifting about without knackering everything.

If you like your books DRM-free, you can also check out the Narratess Itch.io bundles. I am in a couple of these, one for scifi books and one for books between 300 and 499 pages in length. This is a great way to get a whole bunch of books for a good value!

i still did not implement big pext. but i probably made single pext/pdep about twice as fast when bmi2 is fast and there are no ifuncs https://codeberg.org/jjl/bittricks/pulls/16

What we don’t have are many examples of tech that had a limited measurable impact on productivity and economics, whose promise seemed eternally in the future, and whose harms were clear and vocally warned about even before the tech was adopted, which then overcame those objections to see wide use

This worldview is impossible to deal with as it’s based on a fundamentally flawed reading of history.

Our past is filled with tech that was compelling right at the outset, with a clear unambiguous benefit, and then slowly and with faltering steps revealed to be harmful after adoption

I keep encountering, online and off, people who believe if an unethical tech becomes functional enough, that will make all the naysayers abandon their concerns and start using

That is, if LLMs become good enough then surely we will look past the deception, violations, abuse, and extremist politics?

So, wait, the whole “Mythos AI is so powerful it can find exploits in any software” thing requires both access to the source code and thousands of runs to find anything remotely actionable? This is the “too dangerous to release” model they’ve been hyping up?

Is that really it?

obviously amd64 is still not a good architecture and likely never will be a good architecture. but at least we have more toys to play with these days (where available)

dysfun@treehouse.systems ("gaytabase") wrote:

so yeah i'm just gonna declare it, amd64 stopped being a completely suck architecture with x86-64-v3. that doesn't mean it was good then, just that it didn't suck completely.

dysfun@treehouse.systems ("gaytabase") wrote:

if i were writing a compiler and supporting amd64 i am honestly not sure how far back i would bother going at this point. even AMD's BMI2 impl supports SHRX etc. properly (it's only PEXT/PDEP they made super slow). and it means you have amazing tools like the ability to avoid undefined behaviour while zeroing high bits.

dysfun@treehouse.systems ("gaytabase") wrote:

if the cpu supports BMI2, will the compiler prefer to rewrite shifts using e.g. SHRX to avoid clobbering flags?

Back in 2008 W3C sat down with Japanese typesetting experts and created a clear, practical guide to how Japanese text really works so CSS, SVG, and HTML could support it properly on the web.

Specs now point to JLReq for details, and it sparked similar language enablement guides for Arabic, Chinese, Korean, Tibetan, and many more.

Real typographic knowledge, turned into web standards that make the global internet look right in every language.
