Lower Left Fountain Pen Posts – Hack Club Scrapbook

Hello :D It’s been a while, but I wanted to start posting to Scrapbook again, so here’s a little sketch of myself I did to warm up ✨

This marks the moment where I wrote my own JS that actually worked as expected with no help at all! :dino-dance: I figured out how to lose my Sprig game!

Here are two sprig programs I recently put up: The first is two sprites that are connected together, and can't move, The other is a previous snippet of code I wrote which allows you to combine maps. I'm probably going to make more demos, which will show off other useful snippets.

Wrote my first SQL code!

Google Apps Script is very cool… wrote some code to send an email to each attendee that registers for Leland Hacks! Also got to check out our venue :)

i wrote complex vanilla css! woah

i wrote a program to automate the changing of my twitter banner, being my second project to be written in golang that i'd actually share, and deployed it to a digitalocean droplet!

Wrote quite a lot of articles during class! Also figuring how to reach out to people on Twitter and not look like a freak

Wrote a new shader thing, this time to look hand-drawn could make a cool coaster or something who knows Also make a Lorem-Ipsum style text generator, that takes text as input and spits out similar text. The output is meaningless, but at a glance looks like it makes sense. Basically picture 1-Dimensional Wave-Function-Collapse algorithm for text I don't have any output on me, as I'm typing this in Chinese class right now

Today I added new HTML and CSS files to my personal website Repo on GitHub! :github: I also made a few changes to my README Profile, because I wrote new text that I'll add soon and moved my trophies ⭐ theme from Monokai to Gruvbox. Also I learned about what Prettier indentation is thanks to @caleb! Next, today was my last school day before my break so this next two weeks are free and I'll have time to relax, study more, code and make new things! I will also try to work with my workshops and I'll make a pull request to GitHub Docs because I found a typo on their page! 👀 :pullrequest:

finally wrote the code to tint the wing sprite appropriately so worth (also spent wayyy too long on the wing flap)

        const tM = 0.5, vM = 0.75;
        if (t &lt; tM) t = lerp(0, vM, invLerp(0, tM, t));
        else        t = lerp(vM, 1, invLerp(tM, 1, t));

remap is such a useful idea

it’s been a minute since I’ve written a graphql query (actually, not since I worked at github, lmao), but i wrote up a query for an api endpoint to use on contribute.hackclub.com. the query part wasn’t the hard part, but figuring out how to auth with a github app was a little tricky! we got there in the end though 🙂

microworlds.hackclub.dev/?id=a715dc01e85ec95e5cebdf9a50e6ca23 wrote more "shaders" in JS this one makes me nauseous

Attended LancerHacks last weekend and teamed up with @ShubhamPatil and Gautam; it was super fun and we made a nice design for our project on a napkin 😆. Also wrote a short blog post about my experience: maggieliu.dev/posts/lancerhacks

I am weirdly starting to like Typescript. Wrote all my guestbook serverless function code in it, I feel a sense of superiority. And I love Supabase - great UI, great everything. Now for the uploading comments part. My plan is to first validate and sanitize user input, generate a random ID for the comment which is stored in a second table, bcrypt the random ID and store the output hash, send an approval link via a Discord webhook which has the bcrypt output hash in the URL, clicking the link runs a different serverless function which checks the hash in the URL and compares it with the output of hashing the same ID from the second table. Pretty overengineered for a simple guestbook. The things I do to prevent spam.

learning cryptography lol apparently my great great grandparents were big into encryption, and wrote to each other in encrypted letters. I found images of a few, from late 1800's to early 1900's. I'm attempting to crack the code, and so far just trying to transcribe it. Also, apologies for the shitty photos, I'll see if I can find the original letters somewhere. (Also this is a different person than the crazy one from the weird scientific paper I posted, I have interesting family)

So today I had a very interesting talk with friends about Chordates on #biology! 🪲 I'm glad the channel is getting more active again! Also now that it's almost March I'm going to work on the Workshops Projects as I had planned before: I'm going to be making a newer version of the website workshop project 🕸️, which includes a small website for me, some things for friends and a cool website about dinosaurs that I will be hosting using dino.icu! :orpheus: 🦕 Also today I saw some cool fonts while using Google Fonts! :google: 🖋️

I attended blueprint this weekend, so I wrote a small blog post about my experience!

https://cloud-fximh1q3w-hack-club-bot.vercel.app/0blueprint-blog.png

I think the last time I posted here neither the physics nor the sword were a thing. well. they are now! I also wrote like a six paragraph summary in DMs with someone somewhere about what I'm doing differently this time 'round other than simply writing it in C. it's a neat overview of some of the things I've learned about making games in the past year+ since the Rust version. could probably turn that into a neat blog post at some point. I also got the game working on mac. still looking for someone to try it on Windows to see if DirectX has the rendering bug I think it might have. now all that's left to do for feature parity with the original version is um, I guess, physics for the sword, enemy AI, combat, then the bow and arrow, inventory ui, then quests. I want to add cool things you can interact with in the forest like pots you can break, grass you can cut, other assorted RPG tropes.

wrote a little script to switch a bunch of my repos to pnpm because im running out of space 👀 src is here if anyone’s curious, also wrote a little thing that makes it easier for me to use pnpm with other projects that don’t use pnpm, although it doesn’t handle adding new dependencies at all

Went from " i wish they built this feature " to " I'll just write my own feature " . Wrote my own music bar ( listen.moe, Spotify, Mpd ) in lua .

the C port is coming along nicely :) :c: 🌳 🌳 🌳 it can render the same forest, but with much better fps than the Rust version because of a handful of graphics programming tricks I've picked up since then. similarly to @AakankshaRangdal-U02F16CHZA4's post, also made mostly with circles! (okay, nonagons, but still hehe) actually, on that note, I've attached a picture of the original version I made in Rust: do you prefer its circles to the nonagons? let me know by reacting with 🟢 or :stop-green: (technically an octogon, but close enough) repo here: :githubparrot: github.com/cedric-h/rpgc if anyone has a second and would like to try to build and test the native executable on windows, shoot me a DM. I suspect I might have some depth sorting issues on DirectX but want to make sure. 🚧 :blender: I've also attached a picture of what the map looks like in Blender, as well as a tiny glimpse of the script I wrote to export it. if you've played the Rust version then maybe you can guess what each line, diamond, square and circle means 😁

as I port a game I wrote a while ago in Rust to C to try and see how much smaller I can get the WASM bundle size, I've found that what has the biggest impact is the "culture" of the languages. for example, the maps in the game I made are laid out in blender, and then exported to JSON with a custom python script I wrote using blender's API. it's easy to add a Rust dependency to parse the JSON for you, but that bites you in the ass later; serde can inflate your compile times AND your WASM bundle size. in C, however, package management looks different; there are single header libraries that are pretty easy to include, but using libraries isn't very C-like, and unlike Rust, C has a stable ABI. that means that if I change my python script to dump a bunch of floats into the file as binary, I can fread those directly into a bunch of C structs. (I do have to handle endianness for integers, though) in Rust, even if I used #[repr(C)] to force a stable ABI for those structs, I'd still have to jump through a bunch more hoops (unsafe) or pull in a dependency like bincode (which would in turn pull in serde ...). anyway, so I quickly wrote a python metaprogram to generate a C header that can fread (or just memcpy) in all of the binary data into the fields in the game map object that the first python script pulls out of blender

I wrote the start of a 16 bit OS in real mode! I have no clue what the fuck i'm doing, and probably am doing everything wrong, but whatever. my head hurts going to delete and restart now, and do this in 32 bit mode. asm is fun, and i'll miss bios int this is only like a days worth of research and my code is awful
