Show HN: I recorded a video course to let anyone learn Math bottom-up
This course was intended for ages 7 and up, including adults. I really tried to make the material accessible to everyone, and hopefully not be too boring, while it establishes a solid foundation for learning anything else.<p>If you do watch it, let me know if it is helpful in getting a solid foundation!<p>My background: Before I got full-time into software development, I was doing a Ph. D in math at NYU. I thought YouTube needed something like this.
Show HN: Conquer CSS, a free introductory book for CSS [pdf]
I have moved onto other side projects since writing a short book for those looking to cover the fundamentals of CSS, so I made it free and stopped marketing it. Enjoy.

Show HN: Meg-4, the Open Source PICO-8 alternative
Hi fellow hackers,<p>I've created a GPL licensed alternative to the proprietary PICO-8. It also addresses most of its shortcomings:<p>- multilanguage support<p>- uses UTF-8 encoding (BMP only)<p>- sophisticated user input methods (direct codepoint, composition, Hiragana and Katakana etc.)<p>- provides a large and efficient API library for your scripts<p>- supports C, BASIC, Assembly and Lua scripts (more to come)<p>- supports wide variety of file formats (Amiga MOD, MIDI, Tiled TMX, PNG, etc.)<p>- capable of importing PICO-8 and TIC-80 cartridges<p>- runs in your browser: <a href="https://bztsrc.gitlab.io/meg4/" rel="nofollow noreferrer">https://bztsrc.gitlab.io/meg4/</a><p>It might not look like much at first glance, but it surely shows its strengths when you start using it (for example automatic API help as you type in the code editor, or invoking the built-in debugger if your script crashes, things like that which makes development easy and fun).<p>Also check out its well-structured and comprehensive documentation:<p><a href="https://bztsrc.gitlab.io/meg4/manual_en.html" rel="nofollow noreferrer">https://bztsrc.gitlab.io/meg4/manual_en.html</a><p>Binaries are provided for emscripten (web), Windows, Linux (statically linked SDL and GLFW3+portaudio, dynamically linked deb package for Ubuntu and RaspiOS).<p>It is still in early in development, but almost feature complete. At this stage, expect minor bugs here and there, but should work most of the time. The interface is already translated to 25 languages, but the built-in help and the user manual is only available in English for now.<p>Let me know what you think!
Show HN: Roller Coaster (Failed YC S23) – Complex Automations Without Code
Hi HN! I'm Hugo, founder of Roller Coaster. It's a platform that lets you build complex automations without code using visual scripting (a powerful way of building logic visually), and I'm excited to share it with you today.<p>I just launched today, you can try it out here: <a href="https://roller-coaster.app" rel="nofollow noreferrer">https://roller-coaster.app</a>. Here's a 5min introduction to it: <a href="https://youtu.be/1gtdlM774Ug" rel="nofollow noreferrer">https://youtu.be/1gtdlM774Ug</a>.<p>---<p>I'm well aware that there are already a lot of no-code tools out there, but I think they all have a major flaw: they're not powerful enough. They're great for building simple things, but as soon as you want to build something more complex, you're stuck. You can't do it without code.<p>I've been using the Unreal Engine for a previous project and I was amazed by the power of Blueprints, their visual scripting engine. It's basically a way to build logic using nodes that represent functions, and wires that represent data. It's so powerful that you can build entire games without writing a single line of code.<p>I thought it would be awesome to have something similar for the web, to be able to build really <i>anything</i> without code. And that's how Roller Coaster was born.<p>---<p>The challenging part is that visual scripting is not something that can be used without a minimum of training. It's not as easy as drag and drop. So I had to find a way to make it accessible to everyone. That's why I built a gamified tutorial that teaches you how to use it. It's a bit like a game, you have to solve puzzles to progress. It's really fun and I think it's a great way to learn.<p>You can try it out here (it doesn't require any subscription): <a href="https://luna-park.app/challenge" rel="nofollow noreferrer">https://luna-park.app/challenge</a>. Let me know what you think!<p>---<p>For now, Roller Coaster allows you to build webhook-based automations with integrations. I'm planning to support CRONs and webhook, and add more integrations in the future.<p>I'd love to hear your feedback! You can also ask me anything about the project, I'll be happy to answer.

Needed to isolate a bit of DRY logic for some of my projects. Might be of use to others out there.
