Is there an #FOSS Alternative to one particular function in #Office? It's literally the only reason we have a subscription for my wife.

It's the smart 'remove background'. When she's quickly making a label for something in the house, she can take a photo, whack it in Powerpoint, and that remove background makes it very easy (normally 1 button) to make the background go transparent.

Let's see if I can do this with some regularity. Won't be every day, but I'll try. If I hit 5 days a week, I'm going to be happy.

So, with the latest caching changes to my #rust MCTS connect 4 implementation, we've gone from the Python version taking 11m57s for the same amount of episodes, iterations, threads to 33s on the same hardware.

Struggled, but I think it has been worth it.

Also - well and truly over a gig of ram vs ~8mb.

@mjd Are you still looking for work? There's a couple of tech lead roles I can see at our Malvern office that might be a good fit. One particularly.

But - we've got a 3 day in office arrangement, so not sure if that makes it a big no

Not really sure of the best way to implement an MCTS over multiple threads without memory sharing though - manipulating the tree does require actual changes meaning that shoving it in a single thread and doing select/expand/propagate by messages would bog down the rest of the processes.

Alternative would be multiple copies of the tree - but that starts using memory in a way that's not helpful until the locks become a problem.

Multithreading, eh? Gonna have to figure out whether I've done this thing the idiomatic #rust way later... I've got suspicions I haven't. Starting with the fact I've got a bunch of shared memory.

Single thread only so far, and added some cacheing, but yikes that's an improvement in speed.

My code is somehow teasing me.

See that UCB at the very end there? The one that's negative? That's the only good next move.

I bet it's a tiny thing somewhere too.

My #Rust MCTS implementation is actually returning actions! Haven't measured yet, but it's looking like it's speed is very very very good compared to the previous Python implementation.

Unfortunately, it also seems to be returning also exactly the worst possible move each time. It's like that scene in Enter The Spiderverse: You can't get 0% on a multiple choice quiz without knowing the correct answers.

Now, I've just got to figure out where it's flipping.

Almost got enough of the MCTS implemented in the #rust rewrite of #mon2y to hook it up to play connect 4. And maybe then start using it for something useful (ie - help me playtest designs). Or, spend the time of getting it multithreaded).

It's been a good learning experience, but my attempts to make it very generic have made it a tough first Rust project for somebody who hasn't touched a language lower level than Python in 4-5 years.

@TodePond @roundcrisis You're the only two people I've found on Masto who attended #yow24 today!

If you see me around, feel free to say hello! Going to try to hang around until afterwards.

I have programmed in C, C++, C#, VB, Python, Pascal, JavaScript, TypeScript, Lua - most professionally, and I've probably missed some. I've never had issues moving between languages until #rust.

When does Rust start feeling like I'm working in it, and not fighting with it? I'm still early in my Rust journey, but I'm finding no joy in this language.
