I got tired of class-heavy UI code, so I started building Juice

At some point I realized I was spending more time reading class strings than reading the UI itself. Not CSS. Not components. Just giant piles of utility classes. That frustration is what led me to build Juice, an attribute-based UI system for the web. It’s still in alpha, but the core idea is alr...

I gave Claude Code a project-management UI

When working with Claude Code, I sometimes end up with so many plans and tasks that I lost the track of what I was doing... Especially after a computer crash or an unsolicited reboot. So I built orchestrAI — a Rust dashboard that puts a live Claude Code terminal in any browser with all my plans and...

The Day My Argument Parser Outweighed My Neural Network

There's a moment in every ML researcher's life when they look at a training script and realize something has gone wrong — not with the model, but with the code around it. For me, it was staring at a PyTorch training script — just the model, optimizer, and loop, dataset loading aside — where the arg...

Manage Legacy OpenCL Driver in a Distrobox Container!

I would say OpenCL driver support is short-lived. For example, the current Intel Graphics Media Driver for VA-API provides the support way back to Intel Gen 5. On the other hand, Intel Graphics Compute Runtime for OpenCL provides the support for Intel Gen 12+. If you want OpenCL to work at all with...

The data every AI agent needs but nobody sells cleanly — and what you can build on top of it

Freight audit shops charge their customers 3–8% of recovered overcharges to reconcile invoices against published carrier rates. The data input to that business — current LTL fuel surcharge percentages from each carrier, refreshed weekly — costs $0.03 per lookup if you know where to get it. That gap...

Why Go Handles Millions of Connections: User-Space Context Switching, Explained

Somewhere around 40,000 concurrent connections, your Java service falls over. Not from CPU, not from network — from memory, because every connection is a thread and every thread wants its own megabyte of stack. By the time you've finished Googling whether this is a -Xss problem or a ulimit problem,...
