From 53 to 88: A Practical Guide to PageSpeed Optimization for Static Next.js Sites

I spent two weeks optimizing shoofaflam.tv — an Arabic streaming guide with ~20,000 static HTML pages — from a mobile PageSpeed Performance score of 53 to a stable 77-85. The site runs Next.js 16 with output: "export", served by nginx + Cloudflare CDN on a single Hetzner VPS. This isn't a list of "10 tips for faster sites." This is the actual chronological journey, including the regressions, the ...

I Stopped Trying to Keep Up With AI: Here's What Happened Instead

This piece is for anyone who has felt the pressure to constantly keep up in AI and wondered whether there might be another way. The pace is real. The pressure is real. But I'd argue that in a field where everyone is trying to sound like they know everything, the most valuable thing you can do is actually understand something. Fewer things, more deeply, more honestly.

4 JavaScript Frameworks Powering the Generative AI Revolution (and How to Choose)

For a long time, Generative AI was a Python story. If you wanted to build with LLMs, you used Python. Period. But things have changed. The JavaScript and TypeScript ecosystem has grown up, and you can now build complex, production-ready AI apps without leaving your favorite language. But that brings us to the obvious question: Which framework should you actually use? Let's break down the top 4 J...

I built 70 free dev tools in 6 weeks, here's what I learned

Every online tool either makes you create an account, shows you ads, or loads painfully slow. So I built toolkitdesk.com — one URL with everything. What's inside Developer tools JSON formatter, JWT decoder, regex tester, diff checker, Base64, UUID generator, hash generator, URL parser, cURL → Fetch. Text tools Word counter, case converter, markdown editor, find & replace, r...

And then you try to build one yourself for production, and honestly? It's a pretty different experience. Last week in London, we got engineers, tech leads, and builders into a room for Agents in Production, a meetup hosted by Orkes. The w...

Your Ridge Parameter Is PageRank's Damping Factor (and Why BLAS Beats GPU for Mid-Sized KRR)

The ridge parameter λ in kernel regression and the damping factor d in PageRank are the same object. Both create a spectral gap. Both stabilize an otherwise-unstable iteration. Once you see it, four unrelated-looking algorithms collapse into one story. This post is a condensed, math-first write-up of two longer pieces on ki-mathias.de: Eigenvalues & AI — the unification story, with inter...

Why 90% of CS2 Players Are Losing Money on Their Skins (And Don't Even Know It)

Most Counter-Strike 2 players lose money on skins because they treat them like cosmetics instead of assets. Prices depend on wear, float, patterns, and timing—but most sell emotionally and on the wrong platforms. Smart sellers audit value, wait for the right moment, and choose better marketplaces, turning skins into real profit instead of missed opportunity.

I got tired of my GitHub profile card 429ing, so I built an alternative

If you've used github-readme-stats on your profile (the Anurag Hazra one with 70k+ stars) you've probably seen this at least once: Mine broke last month. Then it broke again a week later. I looked into it and found the maintainers themselves recommend self-hosting now, because the public Vercel instance gets rate-limited under traffic. Fair enough — they're a small team serving millions of requ...
