A few weeks ago, I was flipping through one of my old programming magazines when I stumbled across an interesting claim: you can compress images using the Discrete Fourier Transform. The idea seemed almost too elegant to be true - transform an image into the frequency domain, throw away the small stuff, and reconstruct something that still looks decent. This is apparently one of the core mechanisms behind JPEG compression.
I had to try it myself.

Every now and then at Extiri, between shipping apps and squashing bugs, I like to take a detour into a completely different corner of tech — just to see what happens. At my university there was a statistics project that could be made so it served as ane xcuse to work wht ML. So this time, the question was: can I teach a machine learning model to sniff out network attacks? Spoiler: I got it to 97% accuracy, learned a ton, and had a surprisingly good time doing it.
Here’s how this little research adventure played out.

Part of the “The Power of Elegant Simplicity” series - algorithms that hide power in plain sight
You know what’s wild? One of the most elegant cryptographic algorithms ever invented uses nothing more than high school algebra. No complex number theory, no quantum mechanics, just polynomials. The kind you probably learned to hate in 9th grade.
Welcome to Shamir’s Secret Sharing, where a simple quadratic equation becomes the foundation for securing nuclear launch codes, cryptocurrency wallets, and anything else you really, really don’t want falling into the wrong hands.

In the evolving world of AI development, there’s a growing buzz around “filesystems for AI”—essentially, structured ways to organize and access data that empower AI agents to work more intelligently and autonomously. Think of it as giving your AI a well-organized filing cabinet where it can pull out exactly what it needs without rummaging through chaos. This trend is picking up steam because AI agents aren’t just chatbots anymore; they’re becoming active participants in coding, research, and problem-solving workflows. They need reliable, queryable repositories to fetch context, code patterns, or prompts on demand.

We’re copying API keys into ChatGPT prompts, uploading proprietary code to cloud snippet managers, and syncing our entire knowledge bases through servers we don’t control. Somewhere along the way, we normalized sending our most valuable work artifacts through someone else’s infrastructure.
That’s changing in 2026 — and it’s about time.
