Kaeniya

Well, mock exam tmr and flavourtown is ending.
Il see yall afterwards, prayging for that A*
I’ll continue updating the book after flavourtown ends, since its still my notes after all lmao
Idk what to put for the screenshots atp so erm enjoy lol

1.1.3 completed, and added acknowledgements :D
we aren’t getting cooked by OCR mark scheme this time 🔥

OMG
Wanna know what I spent 40 minutes on?
INVESTIGATING WHY CLOUDFLARE’S SIDEBAR DIDNT WORK
cause: cloudflare pages strips the .html from the page
solution: some bloke on github made a fork with the issue fixed a month ago that wasnt merged yet.

so i built his source https://github.com/CattoYT/mdBook/releases/tag/a and hooked it up to cloudflare and now we good
:/

wahoo?

Just completed 1.1.1, 1.1.2, and about to start 1.1.3.
I’m so incredibly behind my revision timetable but it’s fine because CS is really not that hard lmao

https://kyuun.tech/paper_1/1.1/1.1.1_structure_and_function_of_the_processor
https://kyuun.tech/paper_1/1.1/1.1.2_types_of_processor

I think i somehow broke the sidebar on the deployed version so i’ll fix those tmr lol

I completed 1.3.1, and completed more thorough coverage over 1.2.
About to start easter revision for mocks, so writing is probably going to speed up a ton lmao.

Again, this is definitely my least technical project, however its still technically a project since im uploading it to cloudflare and it could help someone else soo ig il track it and upload for ft

bugfixes across the board because I was asked to reship this project, also fixed the initial session creation and maybe fixed non windows installs?

Anyways this is hopefully my last devlog for this project

Thanks to our school, I’ve decided to write my own textbook with mdbook for H446 OCR A Level Computer Science, first commit dropped.

Also thanks to my setting up of perlica.me, I have the stuff set up to already have the site on cloudflare, visible at https://kyuun.tech already :D;

Readme updated, thanks reviewer!
Added compile steps and also fixed some of my cloudflare settings

Im about to get 0 cookies for this project icl
anyways dev log time

• Added random tag lines (refresh to see them)
• I couldn’t figure out how to get the bottom buttons to work the way i wanted them soooooo (ehe)
• redesigned everything for perlica cuz 1. shes really cute 2. i got the perlica.me domain
• switched out the vedal987 link for my slack link (i genuinely have like no public presence so this is hard lmao)
• changed fonts
• uploaded everything to cloudflare (https://perlica.me)

I think this project really just shows that I am not a frontend dev whatsoever and I will promptly return to never ui’ing again
Im sorry that you ever had to vote on this (be generous please I used rust for web dev 😭 this shit is hardd )

So I:

• found out leptos has a show tag that I should have used this entire time
• cried as i realised css animations suck to make
• figured out how to integrate github actions and cloudflare pages
• oh hey https://azuyori-dev.pages.dev/ works now

Anyways i’m still cooking because again, UI’ing sucks and I have to finish magazine soon

Corrected a dependency issue and made readme look better, thanks reviewer XD
i hate python sometimes (always)

I finally had to use ai, the audio libraries in rust are genuinely painful to work with.
Rubato is really fucking complicated and you can’t just populate an empty vec cuz it has to be the exact length because yes
and also the fact taht I can’t document made it a lot harder lmao
anyways i have something that works now, time to shove it into other things

Yet another session of skill issues and shitcoding to produce cancerous code
damn that was bars actually
anyways I spent this time fixing up the button, and a lot of google because, say it with me:
“I HAVE NO CLUE HOW CSS WORKS :D”
i have offended so many people with this, and i wanna ship it soon so I NEVER have to look at this again

THE ANIMATION CASCADES HORIZONTALLY :O

yea no i am spending more time on this than someone reasonably should
web dev sucks
anyways I have 2 tests tmr lets GOOOO
but a lot of cleaning is needed on my codebase, tmr is likely that as well, or making it so that everything is a little more ❇️ reactive ❇️

CHAT I FIGURED OUT HOW TO USE CSS ANIMATONS WITH LEPTOS CAN WE GET 10 LIKES
also I spent some time fixing how each thing is formatted internally to make it a little easier to manage in the future
I suck at webdev take me back to the software side i should not be doing this project LMAO

whoever invented css honestly needs to just stop and make a better solution
also leptos gets complicated fast especially since i don’t think this is the intended use case

The button works and my currnet next plan is to learn about css animations and try and implement it within leptos but idk how thats gonna go
I also wanna figure out how signals actually work so imma need to read through the docs a lot more so yay more hours of reading :D
i also need to revise cuz a level further maths makes me wanna die so wahey

leptos is a pretty cool lib icl
I only wish I could fully avoid html and use something like egui but this is just a website that idk what il hold in it
for science tho its funny asf to write rust for the web
(ive also NEVER written any html, css, or js, nor ever done UI so this is a first XD)
(totally not half inspired by vedal’s website)

Getting majorly skill diffed by ffmpeg cuz i don’t know how this shit works

currently thinking of new solutions in the middle of me supposed to be revising lol
I don’t think ffmpeg is the play i might just find a rust lib to convert my f32s
welp

Had a lot of hmw to do, so a lot less work this time.
A lot of this was comparing different ways of just storing the f32s and fighting the borrow checker (thanks bacon, livesaver there)
Untested, will probably test tmr lmao
Its good to be back on a project that I understand xd

Documentation fully complete (I think?), and the book is also rewritten to include my section :D
Release is now public, i just need to make assets for the project banner (BAD PHOTOSHOP LETS GOOO)
https://github.com/CattoYT/halloy-notify/releases/tag/2025.12

Finally finished config testing and integration :D
Luckily Halloy and serde made this relatively painless, so now the user being pinged and the webhook can be changed.
Documentation is also written (:O) and its all ready to ship :3
I wouldn’t have made it into RED without this horrible fork, so I hope this helps at least someone to get into the best music tracker ever!
Also reviewers, I know this is incredibly specific of a use case, but I swear it works, and it was approved to make as a project xD
https://hackclub.slack.com/archives/C09MATKQM8C/p1767034094401959

The burnout is real 😭
Anyways I think i’ve finished with integrating discord in a somewhat idiomatic way but its completely untested rn, so thats next session’s job.
Having to scour the codebase for how things are done is a genuine pain, thankfully im using Zed rn so its BLAZINGLY FAST but still does my head in pretty badly (halloy is completely undocumented)
I do appreciate rust a lot more because doing this with something like python would be so much worse XD
anyways things to test:

• Config loading
• send on new interview
• I didn’t cause a memory leak or something xd

Well, I passed the RED interview so I don’t really have a use for this project anymore…
I’m going to speedrun finishing it and submit because motivation gone lol
Spent the last hour learning how Halloy stores configs so I can add configging for custom discord webhooks, since before this I just hardcoded everything lmao but since I’m publishing this i probably shouldn’t do that
but yea I made it onto redacted :D and thats the cool part

Another netsplit -> Another session of me fixing up my halloy fork
Got a few changes that I logged from before I started tracking with hackatime (see https://hackclub.slack.com/archives/C09MATKQM8C/p1767061798444009?thread_ts=1767034094.401959&cid=C09MATKQM8C)

• Added discord webhook notifications on new interviews
• Added discord webhook notifications on disconnects/netsplits
• Added discord webhook notifications on highlights

maybe il get round to config stuff and refactoring my very temporary changes XD
I wasn’t expecting to turn this into a project but ig it will be one now

happy new year GMT+0!
Was working on this while listening to vedal and neuro celebrating as well because UK gang on top
Mostly rewriting the recording file and fighting the borrow checker, then realising that what I was trying to do would compile to the simpler thing anyways and have the same performance so idfk :/
Overall neatness improved, debug wav flush works properly, each func doesn’t take ownership of self anymore,
yea just removed skill issues XD

After crying for whatever duration I did, the first release of now dubbed koequet is ready :D
PLEASE USE UV AND NOT THE STANDALONE EXE. ITS 1.6 GIGS 😭

Anyways the last 43 minutes was spent building that exe, few bugfixes, readme, license, and just general prep for first release and also the screenshot below of my shitcode attempt to check sorting, but then realising later on that it will check it anyways XDDDD
either way hey the new banner looks good right? M0nkrous kinda based
anyways first ship lets go!
next ship will be with a gui i hope

Finally dealt with bad files, hopefully next time i make a devlog it won’t be garbage :D
Anyways asset was made, now need to find a way to export this.
All main functionality is there now at least

Not much written, but a lot of research done.
I still have a lot to learn regarding borrow checking and multiple ownership or whatever its atually called
but arc mutex got my back for now il see how long it lasts xd

Very sleepy, been waiting in the queue to interview for RED so not much progress done. Also kinda done with this project and python as a whole. i miss rust XD
Either way, patch notes:

• properly implemented some kind of audio processing for files marked as bad quality
• added another setting
• fixed session and settings saving
  Gonna ship after I make assets :D

Massive refactor across the board with this one
Main changes were:

• fixing session to make it a little more consistent throughout the project
• fixed the exporter code so now it exports a parquet file correctly
• improved the session creation ui
• removed the accidental dox from the parquet file by switching to relative dirs
• general minifixes

but now the project is in a functional state and can do its original job as intended :D
likely will ship here and continue adding features
Example of a Huggingface dataset made from this project: https://huggingface.co/datasets/CattoYT/honkers-railway (hoyoverse no bully me pls)

Idk what to put for the attachment so im just going to put the raw views of the data there from https://parquet-viewer.com lol (the audio is there it just doesnt display on this website)

whole ton of refactoring across the board

• decided to just use deecho+dereverb for the uvr model
• improved compatibility across os’s (probably idk its untested)
• refactored ManualSorter so that the:
• u can now edit the transcripts using ur default editor
• begun work on the exporter and unchatgpting legacy code
• switched from using keyboard to using some weird ass os specific shit so u actually ahve to be tabbed in (epic idiocicy from me)

idk what to screenshot for the attachment icl
enjoy the very wip exporter code

oh hey that looks a lot better
added:

• percentage completion
• transcription in the bottom
• will add capability to edit the transcription
  Maybe il get round to writing a gui soon, probably will ship first then add the gui later
  maybe using gpui-components would be cool since rust is epic and zed is also epic

Oh rust how i missed you
Basically this project is cuz my physics teacher loves to waffle about things and i never know when to take notes, so why not just record the entire thing with transcription lol
Anyways this is mostly just more rust practise for when I do my cs coursework for a levels cuz im gonna do that in rust as well.
enjoy the arc + mutex bullshittery below, but it DOES ACTUALLY WORK YOOO

So i went a little schizo over UVR
tried all of their de-echo and de-reverb models to see if it would work on the type of voice processing that HSR does on some of the voice lines, turns out it was not good at all
rip 43 minutes of my life ig
Gonna try rnnoise next see yall later

Finally made the tui a little nicer, i really wanna try making a gui but im terrified cuz i cant ui for shit
either way also started work on getting uvr going with this so it actually has a purpose

haven’t written python in ages, but i got the basis going for what i need to do
currently trying to make the ui a little more tolerable, but as of now the functionality is ‘there’.
After I fix the ‘tui’ (its so bad) il make it a little more general so you can just go through wav files and manually transcribe or pass through parakeet/whisper, or just do more with it
idk i should be preparing for school but hey who doesnt want a better way to sort audio datasets lmao

I’m working on my first project! This is so exciting. I can’t wait to share more updates as I build.
