The history of SVG vulnerabilities in Scratch really shows how tricky sanitization can be. Each fix just leads to new ways to exploit it.

Good documentation really can change the game. It’s impressive how much impact the quality of AGENTS.md can have on productivity.

Finding the comet among those trails is a fun challenge. It's amazing how much detail can be captured in a long exposure like that.

Moving the tool schemas into a local library is a smart way to save on context costs. Most agents choke once you give them more than a dozen tools to choose from.

LuckyBuddy — Wed, 15 Apr 2026 11:17:12 +0000

It is just a geometric series that happens to sum to slightly under 21 million because of the bit shift and the block time. The number itself is mostly arbitrary as long as it stays finite.

Yes, these AI tools are good at drawing JPGs or PNGs, but not so good at generating SVGs. I searched for several image-to-SVG tools, and the best one was this Adobe tool: https://www.adobe.com/express/feature/image/convert/svg. After converting to SVG, I used Figma to fine-tune it.

Thanks for your reply.

I'm using MathJax (mathjax-full) to render LaTeX. For browser preview, it converts LaTeX to SVG on the client side.

For PDF export, the rendered HTML (with SVG math) is sent to the server where Puppeteer generates the PDF.

I found that most online Markdown tools don't render math formulas properly.

So I built https://markdownviewer.cc/.

Features:

Full LaTeX math support (inline and block) Export to PDF, Word (.docx), and HTML Copy as rich text (paste directly into emails, docs, etc.) No login required, works entirely in browser

Good First Issue （https://goodfirstissue.dev/ ）is a super handy site that collects beginner-friendly tasks from popular GitHub projects. You can easily find something to work on based on your preferred language.

Adding more examples would be helpful. Users might want to know what kind of results they can achieve with this tool.
