Well, that was a nightmare. I have spent the last hour and a half debugging what turned out to be a single line of code, but other than that, today i have started work on the gpu conversion of my walkers thingy. Basic rundown of how it works. I store the data for each walker in a texture, I keep their position and time alive, but not much else. In my case, I store the x position in the top left of an image, (see below), encoded as a 32 bit float (using all four channels because webgl 1.0 only supports 8 bit color channels), the top right keeps the y position. In the bottom left, I keep the time alive (in frames) in the r channel, and whether to render or not (as a bool, 0 or 1) in the g channel. The bottom right is at this point unused. Each frame, I take the previous's frames texture, and render over top of it, updating using a fragment shader (which is not yet written

) Then, I pass that texture to another vertex shader, which generates a bunch of points based of of each pixel in the texture. In theory, its super easy, but in practice... not so much. Encoding the float over the four color channels was not fun, as I kept getting a normal distribution of points even when the initial texture was completely random (and uniform, I checked). I spent a couple hours trying to work that one out only to discover I hadn't unbound one of the webgl globals, so that was fun. Calculating the uv coordinates based only on the point index was ok, but implementing a ping pong frame buffer for the texture update frag shader was a bit tricky. Tomorrow I'll try and get this working, so I've got them functional and moving. Below: Computed texture Rendered walkers (from computed texture) Colored renderered walkers (r: posx, g:posy, b:index)

I may or may not have made the text too large (and also not working on my app for a few days)

Currently working on a non-systemd enabled Fedora 42 CoreOS container image with RPi Web Shell built-in! Not gonna bake and export the image because last time it crashed my entire Pi (it's a Pi 5 with 8g of RAM, but apparently the uSD cannot endure it...). However, i will put the completed Dockerfile on the repo! THATS WHY I NEED SSD ASSESORIES!!!

Here's a not-so-good older image (Fedora 41)

Welp, now its 1 am, but I have made my above demo tidy, did what I wanted with it being user defined, and I think it looks pretty sick. This is the first project for my portfolio site (which itself is not yet built, but oh well) cookiemonsternz.github.io

Changed the layout of all the components on the Bottom layer, brought the pico behind the LCD, and changed the position of the TP4056, JST connector and capacitors. Also replaced the 10uf electrolytic capacitor with a ceramic one and added an ON/OFF switch!

Most of my day today was spent doing an essay, but I also did some of my AOPS homework.

Passing up on the webgl stuff, today, ported my blot submission to use p5js, and reworked it so it actually does what I wanted it to. Might convert this to run on gpu with webgl for journeybook, who knows

Added an error screen and an instructions screen for my website when clicking the start button, depending on if you are on mobile or desktop. Also, set up Nest so I can view my changes on my phone, before committing to GitHub! It really is amazing how useful Nest is! This is an amazing feat since I started web development yesterday! I looked through the docs and used the occasional ChatGPT, and I learnt a lot. I love coding as it allows me to express myself in my own way, to everyone on the World Wide Web

Finally made my obsidian sync backend worked! Available at git.hackclub.app/mathias/obsidian_freesync However, it isn't safe, don't support e2ee nor multiple users

You'll never believe this! I have made two more rotating donuts! One renders using points instead of triangles, and the other uses a stencil buffer to create an outline.

V 0.5 now has route codes! You can see em here - github.com/BennyGaming635/Annouceal/blob/main/app/CODES.md. Also two new routes (Technically 4) Outer Harbour (To and from City) and Port Docks (To and from City). This is gonna be my last update tonight.

I made a website for my GitHub project today and deployed it! I’m not very familiar with web development but did my best and came up with this simple website! spacexplorer11.github.io/Space_Dodge I hope you like it! It’s very simple, I plan to add more, any suggestions, leave in the thread! This is how it looks on mobile

I scrapped the idea of using OpenCV. I am using the tokio library to asynchronously run libcamera and ffmpeg. I have now got libcam to pipe into ffmpeg, I just need to actually get it to work. I have generated one frame, but I'm pretty sure that its not actually camera data... at least I've got some randomness, and its actually outputting something

Just a quick update before I have dinner. Just been working on some more quaternion stuff - this time: Spherical Linear Interpolation. If you know standard interpolation, its just that, but for quaternions. Who would've guessed. I'm pretty sure the "spherical" part comes from the fact it's about angles or something, but tbh I'm not really sure. Anyway, it lets you interpolate between two different quaternions, which is pretty neat. I set my code up so there's two rotating torus (toroids? tori? toruses?? who knows...) off axis from each other, and a third which interpolates between them depending on an input. More coming after dinner, but probs not until tmmrw because I'm not writing one of these at midnight lol. - Blue slerps between red and green.

I'm currently working on a obsidian.md backend for having Sync for free, Almost everything is done (connect, create vault, list files...), I just need add the syncing part (creating file, folder, deleting...) after that, I could add end-to-end encryption (currently, I only support standard encryption) and sharing account.

worked on improving the background gradient transitions in VERT today. the first tab showcases before and the second tab showcases after. it now works using tweening from JS for the gradient position, and mask-image instead of linear-gradient so the color transitioning can be handled from CSS

made a case!! should include tolerances for the pcb/screen so they fit in easily, but securely i've managed to get my 3d printer to be precise up to 0.1mm (which i still find crazy) so this should be easy to print just gotta carve out holes for charging and buttons when i design the pcb cad.onshape.com/documents/cb7162e245d0900f508fcb50/w/940c990f9d72fb5903e72538/e/1f520369415ae0e248c4032d check out progress in #C08MTCZ6GCS|!

Starting this physics textbook on my ipad! (Haliday resnick krane, rereading it after 1 year lol) I need something to discipline me into making progress every day, so ima post on here my progress every day. for today, I got to chapter 4. page 78/1450 haha. Currently It's just talking about some basic vector algebra (cross product, dot product... the usual)

I ran a lot today, and also did some flashcards (no coding projects as I have essays and homework)

I have reworked the code! Now its neatly commented and actually way more tidy.

Finally fixed the potato mace for #C07NQ5QAYNQ|, next bug to fix: making an enchantments that give the Drunk effect (see post from 14/04/2025)

was bored so I made a fun little logo & banner for Modulo, based on the planned dot-matrix UI of the app

After my first scrapbook post yesterday, I thought it would be cool to add a page to my blog that lists these posts. So, after 2 hours of development, here it is. The posts are hidden in details tags, the last post is automatically opened, and the channel names are automatically changed to usable links. blog.mathiasd.fr/scrapbook

https://scrapbook-into-the-redwoods.s3.us-east-1.amazonaws.com/1ed70fcc-2022-40c7-a399-b8e023c281d8-_51564297-d910-45ff-988c-454b7b482d20_.png

For #C07NQ5QAYNQ|, I've developed a mod inspired by Minecraft 24w14potato, entirely focused on potatoes. I've added several foods like mashed potatoes (slot 2), potatoghetti - spaghetti made from potatoes (slot 3), and fries (slot 5). I've also created a "Drunk" effect that randomly moves your hotbar selector, making gameplay more disorienting. With the vodka hat (slot 4), you get a permanent Drunk effect (buggy). The potato mace (slot 1) is a Mace-clone that deals more damage. For the next update, I'm planning an enchantment that will apply the Drunk effect to enemies when hit.
