FBI Carelessly Incinerates Large Amount of Meth, Sending Workers to Hospital

You work for the Federal Bureau of Investigation, and you're sitting on two pounds of seized methamphetamines that you need to get rid of. So what do you do? Burn it all in a pet shelter smack-dab in the middle of town, of course. It sounds beyond parody, but these are the events that played out in Billings, Montana, last Wednesday. And it did not go according to plan. As the Associated Press reports, the toxic smoke cloud from the incinerated meth — a dangerous and addictive stimulant — didn'

Trucker built a scale model of NYC over 21 years

Reno may be “the biggest little city in the world,” but it's got some serious competition from the miniature New York City that hobbyist Joseph Macken built in his upstate New York basement over two decades. “I sat down in my basement, turned the camera on on my phone and just started talking about my first section, which was Downtown Manhattan,” the Clifton Park resident said on a recent Thursday about his viral TikToks on his roughly 50-by-30-foot scale model of the city. “It just took off.” T

Why do we keep gravitating toward complexity?

The Great Pyramids took decades to build. It was a monumental feat of human ingenuity and collaboration. Today, we software developers erect our own pyramids each day - not from stone, but from code. Yet despite far more advanced tools, these systems don’t always make the experience better. So why, when KISS (Keep It Simple, Stupid) is a well-known mantra, do we keep gravitating toward complexity? Marketing > Simplicity Sell me this pen: ✎ What? You don’t know how? Okay, instead, sell me this

CubeSats are fascinating learning tools for space

These are CubeSats. Satellites that are going to space—or at least, the ones I have here are prototypes. But these have one thing in common: they're all powered by either a Raspberry Pi, or a microcontroller. There are already Pis in space, like on Mark Rober's SatGus, on GASPACS, and the Astro Pis on the Space station. Another Pi is going up this weekend, which is why I'm posting this today. I'll get to that one, but I wanted to spend some time talking about two things that fascinate me: Raspb

Parts shortage is the latest problem to hit General Motors production

General Motors will temporarily lay off workers at its Wentzville assembly plant in Missouri. According to a letter sent to employees by the head of the plant and the head of the local union, a shortage of parts is the culprit, and as a result the factory will see "a temporary layoff from September 29-October 19." The plant is about 45 minutes west of St Louis and employs more than 4,000 people to assemble midsize pickup trucks for Chevrolet and GMC, as well as full-size vans. Not every employe

Adding OR logic forced us to confront why users preferred raw SQL

Where This Story Begins In 2022, we had three different query interfaces. Logs had a custom search syntax with no autocomplete. Traces only had predefined filters - no query builder at all. Metrics had a raw PromQL input box where you'd paste queries from somewhere else and hope they worked. Each system spoke a different language. An engineer debugging a production issue had to context-switch not just between data types, but between entirely different mental models of how to query data. When

Automate compile_flags for C/C++ projects on the Zig build system

When using Zig’s build system for C/C++ projects, editors struggle to find include paths and provide proper code intelligence. compile_flagz solves this by automatically generating compile_flags.txt from your build.zig configuration. The Problem Recently I’ve been working on ROLLER, a decompilation project for the 1995 game, Fatal Racing (or Whiplash in NA). The game (known internally as Roller), is an early 3D game written in C with a bespoke engine. It also happens to be one of my favourite

California lawmakers pass SB 79, housing bill that brings dense housing

This is read by an automated voice. Please report any issues or inconsistencies here . California lawmakers just paved the way for a whole lot more housing in the Golden State. In the waning hours of the 2025 legislative session, the state Senate voted 21 to 8 to approve Senate Bill 79 , a landmark housing bill that overrides local zoning laws to expand high-density housing near transit hubs. The controversial bill received a final concurrence vote from the Senate on Friday, a day after passin

Our website looks like an operating system

OpenWrt: A Linux OS targeting embedded devices

The OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application.

A Case Study in AI Overstatement: Builder.ai

Back in May, Builder.ai, once a high-flying startup touted as a path-clearing AI-powered app builder, filed for bankruptcy in the U.S., culminating a spectacular fall that has become a cautionary tale in today’s AI frenzy. The filing followed a flurry of activity that saw creditors seize its accounts, the revelation that it may have been using engineers in India instead of AI, and a probe into how Builder.ai’s founder spent money leading up to its collapse. The collapse has sparked anger among

Because React is not just a scaffold for writing code. It is a philosophy. By using React, you embrace building applications with a pattern of reactivity and
