If you've ever been to PyCon, you know one of the best parts of the expo hall is Startup Row, a stretch of booths where early-stage companies built on Python show off what they're creating. But only attendees get to ...
The culture in the Nuclear Security Enterprise (NSE), particularly with regards to quality, was without a doubt the best I've experienced. One thing that really made it great was the common understanding that perfection is impossible. While that may sound ...
It's now common knowledge that LLMs / AI agents are vulnerable to all kind of injections, so attackers are being more and more creative to find new entrypoints. One commonly

From embedded firmware (where it's badly needed) to big servers passing by cross-platform applications used by billions of people, the foundations of the computing stack are being rewritten in Rust.
A practical, beginner-friendly guide to BF16, FP8, NVFP4, MXFP4, INT4, and GGUF Q4_K_M on NVIDIA DGX Spark. Bytes per parameter, quality vs size, and which format to pick when.
I spoke (a lot) at Microsoft Build in San Francisco!

Workload and node autoscaling in 2026
Tips and tricks from me to you.
Threads were designed to parallelize compute-intensive tasks. However, these days, a lot of applications (such as a network scanner) are I/O (Input / Output) intensive. Thus, threads have two significant
Compilers, especially method just-in-time compilers, operate on one function at a time. It is a natural code unit size, especially for a dynamic language JIT: at a given point in time, what more information can you gather about other parts ...
A practical Wandler deep dive with a local M1 Max WebGPU demo, real latency numbers, architecture diagrams, and getting-started commands.
I've always been a quiet person who prefers to write than to talk (though this may not be obvious based on the number of YouTube videos I've published). So it feels a little weird to say that I think ...
A tmux-like and agent-aware terminal multiplexer.
Let's paint a picture of two very different environments, whose root differences can be largely traced back to differences embedded deep in their quality culture. Let's begin with what sadly is more likely to be the default state. "Quality isn't ...

For many people, Kubernetes Dashboard was their first window into Kubernetes. It offered a simple visual way to see what was running in a cluster, inspect resources, and build confidence without relying on the command line. For years, it helped ...

A post I wrote in 2023, the closing of the canon, predicted that LLM answers would replace search results, dramatically lowering traffic to individual sites, thereby removing the incentives to even write along with building and maintaining websites. Unfortunately, this ...
