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.

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.

@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. :)

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.

lritter,
@lritter@mastodon.gamedev.place avatar

@pervognsen it really is that abstract. the compiler will merge values at shared basic blocks; in conjunction with loops, the combinatorics are cosmic. yet we wish to gather the entire set of possible values with zero loss, so that we can recover invariants at a later point.

i guess this is further complicated by the requirement that operations can be performed on the set.

one interesting way of encoding variable-length strings so that they logically all have the same size is to translate them to linked lists of bits, of which each list "terminates" in a 0 that is connected to itself - so, infinite zeroes.

a benefit of this representation is that negative integers of undefined width can also be encoded this way, by ending in a loopback 1.

strings of infinite length can all be treated as having the same size.

describing an integer -8..7 of arbitrary type, encoded as a binary number, as a digraph of 8 vertices and 14 edges.

the description grows with logarithmic complexity. a full N bit integer set can be described with 2N vertices and 4N - 2 edges.

@pervognsen i would say that the BDD is a subcategory of the more general binary state machine class that i drew an instance of; which is a natural consequence of aggregating all key/value pairs into one structure, then only following the key bits - we naturally land at the value bits; for a BDD, that's either 0 or 1. for a hashmap, that's anything.

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.

i'm looking at contenders for a xterm based gui lib that I can crib from for a scopes based lib. the micro text editor was implemented with tcell, which in turn was heavily inspired by termbox, which looks like a nice minimalistic C implementation to start off of.

i feel all this should be a backend for SDL, so that i can support real graphical environments as well later on, but as far as i know (and please correct me @icculus if i'm wrong) it's out of focus.

You can tell that Chad really isn't much of a Chad at all going by how the usual unit in common parlance is actually the Gigachad.

and here I thought Pascals and Teslas were awkwardly normalized. This is like Farad levels of inconvenient scaling
