Show HN: Sidequest.js – Background jobs for Node.js using your database
Hey HN,<p>I'm the maintainer of node-cron (5M+ downloads/month), and I recently built Sidequest.js, a background job runner for Node.js inspired by Oban (Elixir) and Sidekiq (Rails).<p>It solves some common problems I saw with libraries like node-cron:<p>- Jobs don’t block your API: they run in isolated worker threads<p>- No Redis or vendor lock-in: use Postgres, MySQL, SQLite, or MongoDB<p>- Supports retries, uniqueness, concurrency, snoozing, prioritization<p>- Comes with a CLI and a simple dashboard<p>- Works great in monoliths and doesn’t require extra infra<p>Quick start (no signup needed): <a href="https://docs.sidequestjs.com/quick-start" rel="nofollow">https://docs.sidequestjs.com/quick-start</a><p>GitHub: <a href="https://github.com/sidequestjs/sidequest" rel="nofollow">https://github.com/sidequestjs/sidequest</a><p>Would love feedback or feature suggestions. Happy to answer any questions here!

Show HN: Mathpad – Physical keypad for typing math symbols
Here's something different than your usual fare: A physical keypad that lets you directly type math!<p>Ever tried typing mathematical equations in your code IDE, email, or on Slack? You might know it can be tricky. Mathpad solves this with dedicated keys for Greek letters, calculus symbols, and more. Press the ∫ key and get ∫, in any application that accepts text. It uses Unicode composition, so it works everywhere: Browsers, chat apps, code editors, Word, you name it. Basically, anywhere you can type text, Mathpad lets you type mathematics.<p>I built Mathpad after getting frustrated with the friction of typing equations in e.g. Word, and what a pain in the ass it was to find the specific symbols I needed. I assumed that a product like Mathpad already existed, but that was not true and I had to build it myself.<p>It turned out to be pretty useful! Three years of solo development later, I'm launching on Crowd Supply. One of the trickiest parts of this project was finding someone who could manufacture custom keycaps with mathematical symbols. Shoutout to Loic at 3dkeycap.com for making it possible!<p>Fully open source (hardware + software): <a href="https://github.com/Summa-Cogni/Mathpad">https://github.com/Summa-Cogni/Mathpad</a>

Show HN: Tiny logic and number games I built for my kids
I’ve been building a few small games to help kids (and curious adults) build reasoning and logic skills. Think Word Ladder, Prime Hunter, Math Maze ,all in the browser, no installs. Would love feedback or suggestions for new types of puzzles

Show HN: Kimu – Open-Source Video Editor
I wanted a proper non-linear video editor built for the web. It always annoyed me how there are practically zero functioning web video editors. And here we are :)<p>Kimu can:
- Work with Video, Audio & Text.
- Supports Transitions.
- Non-Linear Video Editing with z-axis overlays.
- Split/trim
- Export
- A cute AI agent (coming soon!)<p>I'm in uni and I started this project out of sheer annoyance that there are zero good web video editors. It is open-source here (<a href="https://github.com/robinroy03/videoeditor" rel="nofollow">https://github.com/robinroy03/videoeditor</a>).<p>What do y'all think?

Show HN: I spent 6 years building a ridiculous wooden pixel display
I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images.<p><a href="https://kilopx.com/" rel="nofollow">https://kilopx.com/</a>

Show HN: NaturalCron – Human-Readable Scheduling for .NET (With Fluent Builder)
Hi HN!<p>I built NaturalCron because I was tired of writing and debugging CRON syntax like:<p><i>/5 </i> * * 5<p>Now you can write something human-readable in .NET:<p>var expression = new NaturalCronExpression("every 5 minutes on friday");<p>Or use a Fluent Builder for strong typing and IDE support:<p>var expression = NaturalCronExpressionBuilder
.Every().Minutes(5)
.On(DayOfWeek.Friday)
.Build();<p>Great for:
- Code-based scheduling in .NET apps
- Overriding schedules from configs or databases
- Displaying easy-to-read rules in UIs<p>NuGet: <a href="https://www.nuget.org/packages/NaturalCron" rel="nofollow">https://www.nuget.org/packages/NaturalCron</a>
GitHub: <a href="https://github.com/hugoj0s3/NaturalCron">https://github.com/hugoj0s3/NaturalCron</a><p>Would love your feedback on syntax, builder design, and what features you'd like to see next!
