Hearing that Recall is exclusive to Copilot+ machines with NPUs is a an extremely good reason to never buy a Copilot+ machine with NPU

@sinbad i switched to linux when i was 25 years old, 19 years ago. i had to give up a few things but picked up a few others. can't say it didn't hurt, but i committed to the bit. i would say it takes about 3 years to acclimate, provided you don't periodically sneak out to secretly huff some colorful fenestres in the garage. needs a full detox.

@sinbad well, should you ever feel in need of a mind-expanding adventure that's not physically taxing, you now know where to look :)

@ca1ne @sinbad you'll find that on linux, in 99% of cases, the answer to "why has this never been fixed" is "capitalism"

e.g. why doesn't inkscape have pantone colors? capitalism!

@julienbarnoin @sinbad i started with gentoo, then arch and eventually stuck with ubuntu. it took me 3 years before i felt settled in. and i would say 3 years is a constant with many fundamental life changes: losing a partner, starting a new relationship, switching jobs, moving places. i often find after 3 years that i haven't had an annoying change-related event in a while.

@sinbad @julienbarnoin right. the hardware has to match the software. when i buy laptops, PC gear and so on, i always look up online for compliance and issues. it is difficult to retrofit hardware with proprietary drivers (whose license sometimes the IHV doesn't own, can you believe it!) for an open OS. and the reason for that is, well i said it before.

@sinbad @ca1ne yeah. well it helped that in 2005 my hard drive crashed and i had no backups so suddenly i had no shit to do at all.

Does anyone know of any code laying around the net that distributes points on a mesh in a blue noise distribution?
A student intern i work with is looking for this. It's tempting to write it, but im also kinda swamped :X

@demofox sounds like if you can do it uniform randomly, blue noise is corollary

@demofox i wonder how much tris are good proxies. like, the furthest point away should lie within the furthest triangle away?

@mrsbeanbag TIL

@mrsbeanbag BWT is quite inspiring. a RLE-friendly transform that is reversible without auxiliary information isn't something you see every day.

lritter,
@lritter@mastodon.gamedev.place avatar

@mrsbeanbag the sequences above btw have both been generated by the same algorithm: we interpolate two permutations of a string by collecting all swaps that would correct a character, sort by cost of swap (where smaller distance is cheaper), then each iteration pick either the cheapest, the most expensive, or the median expensive transform from all options (i forgot which ones i took)

I've been using Linux since it was first practically available (early 90's), UNIX before that, a variety of other OSs including UNIX derived NeXTSTEP, and I can genuinely say that Windows has many advantages and continues to do so.

Whilst part of the advantage comes from being the primary OS (for games, 96.76% market share on Steam), some comes from its feature set.

Most programs which work continue to do so (I have a 25 year old game I made, for which the installer and game still work).

@dougbinks the problems with windows are mostly not of a technical nature. personally, i would disappropriate microsoft and open source it.

I can't be bothered to look up the facts about the windows 11 ai thing, but I'm genuinely baffled as to who wants this, as well as why they need special ai hardware to make a keylogger that also watches you look at porn or whatever else it is that people use computers for

@aeva i would argue that this is actually for no one. it is theater for the shareholders who are supposed to believe that the company is innovating.

> With Recall, locating files in a large download pileup or revisiting your browser history is easy. You can give commands to Recall in natural language, eliminating the need to type precise commands.

"We suck at UX so we'll need to record everything and run on a 40+ TOPS CPU to be able to provide even the most basic functionality. Do you like this, is this good?"

I'm sorry, but AI is mostly just doing simple things, incredibly inefficiently, in the most creepy way.

New Blog Post: A Low Discrepancy Shuffle Iterator (+Random Access & Inversion)

What if you had a shuffle iterator that could traverse a shuffle, without actually shuffling.

What if that shuffle was a low discrepancy sequence so neighboring values were very different and had nice numerical properties?

Another POV: selection without replacement. stateless, and low discrepancy.

lritter,
@lritter@mastodon.gamedev.place avatar

@demofox oh nice. i wrote one that pulls items from a set (a shuffling ring buffer, see screenshout for demo output), but doing this without a set at all is excellent :)

oh wow, and yours is invertible, even. :)

if programmers had a flag, we'd probably have two symbols on it, one for choice, and one for repetition.

interesting problem: progressively mapping a cosmically high number of unique strings of arbitrary length to an ordered set so that we can assign an index to each string, extract a substring from each index, and filter strings not in the set.

evidently, this approach requires compression. the compressed result is functionally equivalent to a regular expression, or a schema validation system.

been experimenting yesterday with a 1-bit trie, and that made clearer to me how tries and hashmaps relate to interpretation and compilation.

in an interpreter, each instruction only takes single arguments and outputs single arguments to produce definite results.

compilers however attempt to partially specialize functions, which we typically implement using types; but what we're really doing is use types as an approximation for the set of all possible values that could go into a function.
