i dont get practicing by using leetcode over projects why cry over one small problem when you can cry over a dozen interwoven ones at the same time? i thought computer scientists liked efficiency

So I'm trying to finetune llama 3 based on old discord messages I've sent to make a new Bungles bot.

simple enough. extract a list of messages I've sent that fit the criteria I give it -- there are 48450 total -- then generate some fake messages for those to be in reply to. That way I don't need to include anyone else's messages, which simplifies things a lot.

I did it before with ~5k dril tweets to make a shitposter bot for my Discord server.

except this time there's so many messages that the preprocessing will take roughly 50 hours. that's before the finetuning starts (the finetune won't take NEARLY as long, luckily)

uncontrolled teleportation huh ?

I hope to control it one day…

Was troubleshooting an issue with a program where I wanted it to run multiple parallel subprocesses only for most of them to seemingly stall. Turns out it was because I didn't know how the multiprocessing function I was using runs in the background.

There's a Python class called Pool() and it has a function map() which takes a function and a list of arguments. Pool will run parallel instances of the function with every item in the argument list you give it.

I assumed that the way it would work was if I allow Pool to run p subprocesses and there are n arguments in my list, Pool would run the first p arguments in my list and whenever one subprocess finished, Pool would start a new subprocess with the next available argument.

Turns out that Pool instead breaks the argument list into smaller sublists and assigns each subprocess one of those sublists. So instead of assigning the first subprocess to handle the first argument, then the next subprocess the next, etc. It assigns the first x arguments to be handled by subprocess 1, the next x arguments to subprocess 2, etc.

The issue I had was I had 922 files I needed to process and the runtime was directly related to the file sizes. The smallest file was 5.6 KB and the largest was 229.8 MB. I sorted the file names in my argument list by file size from largest to smallest expecting the largest files to be processed first and then the subprocesses would gradually work on the smaller ones.

Instead, all the largest files got assigned to a single subprocess. It probably was assigned 60% of the total workload. And every subsequent subprocess would be handed smaller and smaller pieces of the workload.

So those subprocesses weren't stalled. Pool ran out of tasks for them to do and the whole thing had to wait on the subprocesses that were given all the heavy tasks I was hoping to divide across them.

It would have been faster to completely randomize the list first.

🎄💾🗓️ Day 10: Retrocomputing Advent Calendar - BeOS 🎄💾🗓️

BeOS, developed by Be Inc. in the mid-1990s, was an operating system for multimedia applications, multitasking, and multithreading. Initially designed for the BeBox—a proprietary hardware platform featuring dual PowerPC processors—BeOS was later ported to the Macintosh and x86 architectures. Its kernel was monolithic, and the system was primarily written in C++. It featured a 64-bit journaling Be File System (BFS), which supported metadata and allowed rapid file queries and fast performance for multimedia tasks. Despite its technical strengths, including support for symmetric multiprocessing and a responsive graphical user interface, BeOS struggled to gain market traction. Development ceased in 2001 after Palm Inc. acquired Be Inc.'s assets. BeOS continues through Haiku, an open-source project aiming for binary compatibility with BeOS R5.

A bunch of resources and links for this one!

Hello! Would you ever consider bringing back different post types, especially audio? I appreciate that audio posts now display the artist, song title, and album name, but unfortunately newer audio posts don’t play in Tumblr-based music players like egoisticalgoat.de or robinpx.github.io/boombox because they’re read as text posts. Thank you for reading!

Answer: Hey there, @stepintomusic!

Sadly, the answer here is no. We’ve been moving away from legacy post types and towards the Neue Post Format—a format that allows multiple types of media in the same post—for many years. The new features available in NPF basically guarantee that we won’t ever switch back to the legacy format.

(If you’re interested in peeking behind the scenes here, there are a few posts about NPF over at @engineering.)

Now, to get into the meat of the issue. While it would be amazing if we could support every third-party tool forever, the reality is that we can’t. We’re a surprisingly small team to begin with, and even if we weren’t, that support would come at a cost.

To start, there’s the development tax. Now, would it have been cool to ensure all third-party tools (and all custom themes) worked 100% perfectly with posts stored as NPF before releasing NPF to the public? Yeah, it would have been… for third-party tools and custom themes. For us, it would have meant delaying NPF (and all the features it brings with it) for months, possibly years. Imagine a 2023 where Tumblr still doesn’t have polls: that’s the alternate future we’re talking about here.

And then, there’s our maintenance tax. The engine that powers Tumblr themes is already incredibly complicated—complicated to the point that we’re already finding it difficult to maintain and add things like, as you mentioned, NPF audio metadata. If, every time we found some third-party tool that doesn’t play nice with the latest changes, we tried to make an affordance for it… the engine would just become even more complex. And it would do so quickly, and complex to the point of being impossible to keep up with as a maintainer.

There’s a great article here by a former Mozilla developer about the pitfalls of prioritizing a third-party ecosystem over your own software. Did you know that Firefox was essentially a single-threaded application until 2018? This meant it would still visually lock up when saving files to disk, or collecting crash data. Chrome launched in 2008 and was multiprocess from the start. But it took Firefox ten years to catch up because supporting all existing third-party add-ons was seen as necessary. (Spoiler alert: in the end, they had to drop support for those add-ons anyway.)

My own recommendation around third-party software like this is: get in contact with its developer! If something in their software isn’t working, there’s nobody more qualified to update it. (Or, if they’ve abandoned the project but had made it open-source, maybe someone else could step up to maintain it. Maybe you! You never know until you try.)

I talked about the maintenance tax from the first-party side, but let’s talk about it from the third-party side, too. As a theme author and add-on developer myself, I have long accepted that the cost of maintaining these things can never be zero. When your software interacts with an online service, and that online service is being actively maintained, your software also needs to be maintained.

I hope all this has been enlightening! Thanks for your question, and please, have a great day.

I keep seeing letsplays described as "Foobar SMP" and I'm not so much as a nerd that I assume it HAS to mean "symmetric multiprocessing"

But I am enough of a nerd that I instead get "symmetric multi-player"

[utopicwork]

Okay, got multiprocessing working, next thing is going to be setting up a process and interprocess queue for downloading

[nikjag]

rust server project

i learned how to do basic multiprocessing with message passing, the basics of how tcp works, and how to write a terminal based ui (using https://github.com/ratatui-org/ratatui in case anyone is interested) just to see funky lines on my screen

(its slow because my laptop cannot handle obs if its life depended on it)

its just a simple terminal based app that just displays how much of the cpu a client is using and some basic ping statistics

it was utterly painfully learning how deadlock works and i did not have a clue what i was doing but i had fun so yea would recommend

Can you recommend a multiprocess welder for at home garage projects? or just what brand you like

My personal favorite for little at-home hobby machines is Everlast, I think they’re a great bang for your buck and run real smooth. Also I’ve never personally used one but a few friends have had good luck with Eastwood machines
