Getting through winter volunteering commitments that end soon, and daydreaming about learning some new skills.

I have Python experience as a data engineer and I want to revisit Django. And my kid is getting into the Roblox studio GUI tools and I want to work on a Lua project with him to get him started with SDLC concepts and an IDE.

TBD exactly what that will look like or what direction it will go.

I'm working on a tool called Font of Web https://fontofweb.com that helps identify the fonts used on any website. It not only detects the fonts but also shows exactly where they're used (which HTML elements) and how they're styled (weight, line height, size, letter spacing). My goal is to build a comprehensive database of font usage across the web. By collecting and analyzing this data, I believe we can uncover valua…

> I've now rebuilt the tool from the ground up, switching from a Puppeteer-based crawler to an invisible iframe approach. Where can I go to learn more about your invisible ` ` approach/implementation?

I figured it out mostly from first principles. It's such a niche crawling method that was perfectly limited to my use-case, and there's alot to say. But the main idea is that you can inject a crawling script in the html of the site via a proxy you control. E.g proxy.yoursite.com?url=. Then once you've got the data you can call window.postMessage(data) to communicate with the main window.

It's somewhat similar to how browser proxies like: https://proxyium.com/ and https://www.proxysite.com/ fetch the html on your behalf.

I’m working on a programming language for robots called Mech!

https://github.com/mech-lang/mech

Mostly a research project until I find some more people interested in pushing it further.

A recent blog for anyone who wants to check it out: https://mech-lang.org/post/2025-01-09-programming-chatgpt/

Working on my startup https://wetarseel.ai which uses WhatsApp API for message broadcasts and creating whatsapp bots to converse with incoming messages.

This looks cool.

You might want to pass the landing page copy though a spell checker or LLM:

I’m creating an observability tool that I’m trying to make user-centric while staying developer friendly. Most of the tools for remote logging, live dashboards and alerts are either too big, too expensive, or have a “per seat” plan, and incorporate the famous “home” screen with metrics and tips you absolutely never care of. I’m also trying to stay cheap and focused on very few techs (node, Postgres, docker, react) an…

> Even if I don’t get any customers I’ll continue developing it for my own needs! That’s the spirit! A buddy of mine created a tool/API to solve his own problems, opened it to the public and launched it, but he got very few sign-ups, so he just continued to use it for himself. Recently, about two years later and out of nowhere (without doing anything other than the original bit of SEO he did), he started to see a bun…

That's so refreshing to hear to be honest! I've went on so many side projects hoping I would see adoption for months and was basically chasing the dream. However I've came to realize that I really take happiness in developing things sustainably over time, with small steps, and most importantly for myself and what I would like a product to look like. Lately I've even been able to onboard a friend on it using it for his own projects as well, couldn't be happier so far.

If you ever have feedback/advices, don't hesitate to reach me out on contact[at]halftheopposite.dev and I'll happily answer.

Ultra-fast rise-time pulse generators! Yeah, hardware -- or, hooray, hardware!

A few months back, I got excited about pulse generators that had rise times on the order of 15 to 30 picoseconds. There aren't a lot of those available, and I was curious about what would go into their design. so I decided to build my own. https://voltative.com/pulser

A new YouTube app/player, for my kids.

It allows us to control the algorithm. It’s all LLM translating to YouTube search queries under the hood.

Visually it looks the same.

The suggested videos come from predefined buckets on topics they love.

E.g. 33% fun math, 33% DIY engineering, 33% creative activities.

Video recommendations that have a banned word in the title/desc don't get displayed e.g. MrBeast, anything with Minecraft in it, never gets surfaced.

For anyone interested in using it, send me an email.

I'll put you on my list. And you can contribute ideas to our community Google Doc.

I'm building an interactive, web-based Python tutorial site intended to help with learning basic syntax. Originally it was for my kids who wanted to learn to code, but... might be useful to others. https://learnpy.dev The content needs some work, but I'm pretty happy with the framework / UX. I would love to get any feedback from folks who check it out! (The first section is just multi-guess questions as part of the i…

I'm happy you're working on this.

The best option I've found for my son (8yo) is this, but it's a little dry for a child: https://programming-25.mooc.fi/
