@jc – Hack Club Scrapbook

3:23am

Day 95 to 2024: I've been working on something with lights and Pyodide (pyodide.org/en/stable)! I'll reveal more information in tomorrow's post but Pyodide is pretty darn cool - it lets you run Python in the web in a way that makes sense. Other things I've been working on include trying to get #scrapbook to work and also something broiling in #clue-game... (although it doesn't work yet haha)

if you know me, i've been working on marrow (github.com/jianmin-chen/marrow) in my free time and have about ~2300 loc (in the v2 branch) on it (which is absurd until you realize i've been working on this since the start of late april/early may). anyhow, i finally reached a point where i realized that writing it all in c might not be the best thing, esp. if i wanted to extend it, since i hadn't really taken it into account. rather than digging through those loc, i decided: i'm going to rewrite it in rust! (and another thing i also want to work on is building some sort of very very basic terminal emulator for it called stem potentially.) so the first thing to do is to learn rust actually. initially marrow was built on some of the functions introduced in build your own editor, so right now i'm going through a similar guide but in rust. rust is actually real cool! will post more thoughts on it as i work through the guide.

cool stuff!

i've spent the entire day working on these! with the help of the raytracer challenge. i was going to write this in rust, but i decided to jump on the wagon with python again. think i'll work on something else in rust, but probably at outernet / after this summer

hi! i’ve been a bit inactive in this slack but i’m officially back! just wanted to share a couple things i’ve been working on: marrow, markright, and the star of the show, arson! arson :fireball: is a programming language, around, well, ARSON! what else. (excuse the bad inside joke.)👇 here’s a demo of me writing a sudoku puzzle solver in arson with marrow, a text editor i’ve been working on using this amazing guide on writing one in c that i’ve been expanding upon! because i want my own vim alternative but mostly for funsies and to learn c. another things: markright! some people might know that i wrote my own markdown parser a while ago along with a web ui. the web ui has been improved and looks a lot better! (although i have a couple issues to fix in chrome). comes w/ google oauth (i kind of skimped on adding extra auth options) and a recursive filesystem. demo also below 👇 extra things i did or am working on icyi at www.jianminchen.com/article/general/2023-06-04! going forward planning to work on more hc-centric stuff!

Small ship (bigger one coming soon hehe)! At #horizon I built an unnecessarily ~complicated~ hacky project involving Spotify + Neopixels. Basically, the web interface at horizonmusic.vercel.app allows everyone to add music to a Spotify playlist that I play (which means I have ultimate control I guess + yes you can technically still add music) without having to log in (especially if they don't have an account) + automatically filters out explicit songs in the search so nobody adds explicit songs. Waveform with p5.js and Tone.js record surround sound (coming from speakers and other close noise) and transform it into a cool waveform, while a set of LED lights (Neopixels) flash along to the music, utilizing an Adafruit Feather Huzzah to wirelessly communicate with a computer (computer mic -> computer -> computer processing -> send FPS to Adafruit -> flash Neopixels!) through the amazing audio-reactive-led-strip library. The Neopixels we got didn't work fully, but the result was still cool! github.com/jianmin-chen/spotify-collab (and I might be getting working Neopixels for another project!)

Day 4/10 of #10-days-in-public! Started working on the forum, really jumped over the place and also worked on some media queries for the landing page. Worked on some other stuff that may be shipped soon :sunglassesblob:

Super busy today but styled the settings modal for day 3/10 of #10-days-in-public!

Wed, Nov 30, 2022

Day 2/10 of #10-days-in-public! I'm mostly done with the blog and blog post page, and starting work on a little settings modal.

Mon, Nov 28, 2022

Day 1 of #10-days-in-public, again! I'me trying to finish the design of a website I've been procrastinating on. Today, I mostly gauged my progress and started working on the design for the blog. It's kind of hard to record in action haha so what I do today is going to be recorded tomorrow and so on.

Fri, Nov 11, 2022

Finally got around to updating the README for the Markdown parser I wrote during #10-days-in-public! You can check it out at github.com/jianmin-chen/markdown-parser/blob/main/README.md

Wrote a little Python script to change the background on my computer every so often. Probably could have found something, but this is more fun :)

Last day of #10-days-in-public! Unfortunately, I didn't get to attend the Zoom meet, but I just wanted to add my own two cents and say that it was a lot of fun building and sharing the progress of a project in 10 days. Today, I simply finished my write-up, rewrote some of my CSS (adding media queries), and updated the README of my repo. And of course, an obligatory demo of me using the Markdown parser to finish the rest of my write-up: > What's this? A Markdown parser written from scratch. Demo at jianmin-chen.github.io/markdown-parser, write-up at www.jianminchen.com/article/general/2022-10-07-markdown-parser

Fri, Oct 14, 2022

Day 9/10 of #10-days-in-public! I can't believe that there's one more day. Today, I worked on adding strikethrough, superscript, and subscript features, and started working on a contextmenu, which currently allows me to delete files. I plan on adding more to the contextmenu, and definitely finishing the write-up and adding a README to the GitHub repo. (Currently, I also have some incomplete TypeScript files.) > What's this?

Day 8/10 for #10-days-in-public! Today, I worked on adding link and image functionality, learning about regular expressions along the way. Everything's coming together, which is super cool! > What's this? A Markdown parser built from scratch in JavaScript.

Day 7/10 for #10-days-in-public! Was super busy today - got home from a cross country meet and then homework - so I just worked on translating some of the code I've written so far into TypeScript (as a way of learning it). I learned about definition files, and kind of want to write my own to represent the tokens. > What's this? A Markdown parser built from scratch in JavaScript.

Day 6/10 for #10-days-in-public! Today, I added bullet list and number list functionality. I also got a ~little~ bit sidetracked and transformed the parser into a complete Markdown editor, with the ability to add and save files (currently through localStorage, I'm thinking of creating an Express & AWS API after the ten day challenge so that this can be a functional mini Markdown editor, especially since I'm planning to do the Quality Assurance course on freeCodeCamp at www.freecodecamp.org/learn/quality-assurance. We'll see. > What's this? A Markdown parser built from scratch in JavaScript.

Day 5/10 for #10-days-in-public - we're halfway through already, somehow! Today I worked on adding bold text to the parser, as well as tab completion... not exactly part of a parser, but still cool to implement none the less. As usual, a small demo and the write-up at www.jianminchen.com/article/general/2022-10-07-markdown-parser. > What's this? A small attempt to write a Markdown parser from scratch.

Day 4 of #10-days-in-public! I struggled with getting code blocks to work, but I finally figured it out after ~two hours! I've also started a basic writeup at www.jianminchen.com/article/general/2022-10-07-markdown-parser. Current demo is on GitHub Pages at jianmin-chen.github.io/markdown-parser, which I might link to my personal domain sometime.

I've been super busy today, so I couldn't get much done for day 3 of #10-days-in-public. However, I did get a GitHub repo up at github.com/jianmin-chen/markdown-parser with the current code, and I'm writing up the post right now!

(Trying again.) Day 2 of #10-days-in-public! I got blockquotes, inline code, italics, and horizontal breaks working. I'm thinking of working on code blocks next, and getting a GitHub repo and blog post up and running.

Wed, Oct 5, 2022

Day 1/10 for #10-days-in-public! (I might do a day 1.5, we'll see.) I currently have headers working in my Markdown parser, which is pretty neat!

I won $50 in Replit's Template Jam with this small canvas template: replit.com/@jianmin-chen/canvas-sketch-template! I'm probably going to use the funds to get the supplies needed to salvage my old, broken laptop from 2013 and turn it's LCD screen into a monitor :sunglassesblob:
