Python Posts – Hack Club Scrapbook

Never too much map-of-the-slack-ery! Working on un-jank-ifying code and turning it into a basic python CLI with click #100-days :picasso:

I love maps! (well I guess this is python, so dictionaries :)) - anyways here's some map-of-the-slack-ery, now taking into account member lists of each channel. Still very jank, but that'll be changing soon! Less janky code + postgres + CLI tool is next, before refining the labeling process and moving onto clustering #100-days :picasso:

Some more Slack cartography! Used python to download the latest 150 messages from public channels and extract keywords, combine with other labels such as channel size, and then use those labels to calculate channel similarity. Obviously not done yet, but I think the general process is looking nice, just need to refine label generation. Never dealt with JSON files over 200mb though! #100-days :picasso:

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)

Back to developing CLI tools. This time, I made a file watcher for Python files, and wow, it was easier than I thought it would be and the result came out super clean! Pretty hyped to ship this one! :python:

Mega UIL Score table version 2.0: I actually have 2023 data now, and sorting kinda works. Getting ready to publish the data collection Python script and rendering JS frontend soon. ipfs.karmanyaah.malhotra.cc/ipfs/QmP65VKrAwLakZZRiJ3861RZW2PvP7znrkCPkULaS2J1Rh

I’m learning today how to use OpenAI’s whisper model and ffmpeg to convert videos to audio, then to transcribe it for a personal media library, which has brought a lot of challenges since I don’t work with python programs often! My computer is absolutely dying but when choosing the size of the model to use I didn’t want to settle for tiny :uw_devil:. I’m feeling like there should be a Mac app that does all of this for free and with customizable options for inexperienced users with the command line like myself, so maybe I’ll build one one day!

I ~~wasted~~spent my whole day making a mega UIL result table. It's not very good, but using Python to scrape the website and Tabulate/JS (the bane of my existence) to table it, I'm making progress. It's also surprisingly fast at filtering, given it's all JS. ipfs.karmanyaah.malhotra.cc/ipfs/QmRhU23SFgfP4ku4c3X4BK2rKkkduNf7tmFmND24srstPb

I made a standalone PNG Polyglot generator today. A low dependency, low memory way to hide scripts in PNGs, because it's made to run in CircuitPython. gist.github.com/karmanyaahm/03025089054fa4568bc47eb14d1aff51 (offspring of winter hardware wonderland #hardware-party Project Oreo)

Mohan Day 6-10 days update - github.com/hackclub/winter/blob/main/vmss2009.md Finally I made it. Now, RFID reader is detecting the RFID card presented to it. Then a python module running on RPI is constantly listening to RFID. Once RFID card is detected, the code is updated to a JSON file. This JSON file is hosted in local host. FlutterFlow platform gets this JSON by posting GET request to the local host URI. Then FlutterFlow validates from Firestore database and gets relevant data to be displayed and shows it on monitor. Things to improve. - Refresh rate is currently around 30 secs. This needs to be reduced to 5 to 10 secs. i.e the time it takes for the data to show up once RFID card is presented by user. - I should make the hardware cheaper by eliminating RPI if possible! vmss2009-winter-hardware-party

Day 10 of Winter Hardware Wonderland I started on Day 0 and now a final day! I completed my project. Moreover, I learned how to solder and a lot of other Python packages. I also setup my very first Raspberry Pi. It was a lot learning. I didn't have any update today but I would like to recap. My project is a pixel art frame with LEDs that can display image into led. It can also Display slope intercept form Show current playing Spotify Song cover Display the pixel art that is drawn on Pixel Art Editor. I have plans to add more functions too. However it was a lot fun!

3/10 of winter wonderland! don't have many screenshots to send, since today I was cleaning up the repo which will house the code used. as of writing, there's currently a small demo program, which is used to verify the bluetooth console, tft display and geiger module are working, along with libraries to interface with the geiger over i2c. you can find it here -> github.com/geschmit/microgeiger (additionally, crispy jpeg meme so scrappy doesn't delete my post)

Day 3 of Winter Hardware Wonderland :winter-hardware-wonderland:, building Project Oreo, a custom USB rubber ducky: I got some sick renders of the case (Inventor Ray Tracing). Hopefully the prototype print tomorrow is successful, then I can send it to @KaiZheng-U049N5Y0WM9 🤞 On the software side, I have the core code (capture the first 10 setup packets and make a python function to receive them). It just doesn't work 😦. TODO Debug

Laser Cutter, Day 2 | The frame has been assembled and XY motion is achieved. There are minor issues with the laser tube and the 3D prints. Tomorrow Doruk and I will do some troubleshooting and hopefully get this perhaps-way-too-hacky laser cutter to perform the basic set of actions which it is named after.

Day 3 of hardware wonderland: Setup hardware and tried using rpi-rgb-led-matrix library. Also created a Python script to display slope intercept form on the matrix panel.

Day 2 of Winter Wonderland #hardware-party :winter-hardware-wonderland:, building Project Oreo, a custom rubber ducky. On the software side, I got CircuitPython building in a Pure Nix Shell. Turns out, some Python libraries are built using flint instead of setup.py. Thankfully, there's a mode in Nix to handle that. I can now modify the code that ships with a UF2 by default, making deployment just a one-file-copy (very important when you have 20 of something). Next steps: Look at Micropython manifests to figure out how to include data/image files in the UF2. Track the received setup packets (host fingerprint), and make a function to transmit those to Python from C. On the Hardware side, my friend designed and 3d printed the first prototype of the case at school. It doesn't quite fit (see USB Port area), so needs a second prototype.

Winter wonderland Day 2 :winter-hardware-wonderland: Hello again from Melbourne! Here’s my day 2 progress: • Installed the rest of the hardware • Flashed the micro sd card with raspberry pi OS • Started building Python 3.11 ( turns out it takes forever on a pi)

Day 8/10 of #10-days-in-public! Completed day 6 of AoC, it was much easier than I thought it'd be. Did a lot of work on my "copyright infringement detector" project, sketched a data model for storing perceptual hashes of our videos, hosted a redis instance on digital ocean and pushed all our data on it. Wrote a lot of python, and ffmpeg scripts for the project, kinda getting the hang of python now.

Day 1/10: Made it through chapter 1, and starting on chapter 2 of the Deep Learning with Python book. My goal is to understand some of the fundamental concepts of neural networks in the next 10 days. I wrote and trained my first neural network! (but I don’t understand the code at all). See hackclub.slack.com/archives/C01D7AHKMPF/p1669597204292789 if you want to join the learning group I’m putting together!

Working on a Python notebook to make transcribing audio files really easy. I’m adapting a notebook made by someone else to be easier to use, to export Markdown, and to run faster with cached models / pip packages. I previously made github.com/zachlatta/openai-whisper-speaker-identification and this is an attempt to improve the quality of the output (it would previously sometimes mix speakers up).

I modified a Python notebook that transcribes audio files using OpenAI’s Whisper model and breaks the text out by speaker to have clean Markdown output. It’s pretty cool! Give it a try: github.com/zachlatta/openai-whisper-speaker-identification Once you click “Open in Colab” go to Runtime > Run all and then upload an audio file. It will then transcribe the file and download a Markdown file with the transcript, with speakers broken out!

Day one of #10-days-in-public ! I got started on my first hacktoverfest PR! I spent too long fixing my different python installs since it seems like they all pull from different versions and make a mess! After that I worked on a PR for Pandas which I’m nearly done with; just a few bugs to fix!
