Homebrew

Is anyone here interested in contributing to this OS?

A clean-slate x86_64 microkernel operating system built from scratch. No POSIX baggage, no legacy Unix assumptions. The kernel stays minimal: scheduling, memory management, IPC ports, and hardware abstraction.

Show HN: macOS menu bar gauges for your Claude Code quota

Menu bar gauges for your Claude Code quota — one bar per account, like this: (drawn for dark menu bars — white outlines) - Each bar shows the 5-hour-window utilization for one account, colored green / orange (≥70%) / red (≥90%). - When the 5-hour window is fully used, the bar shows a countdown until reset ( 4:28 ) instead of the percentage. When the weekly limit is hit, the bar turns black with a countdown to the weekly reset ( 2D ) — that's the harder cap, whatever the 5-hour window says.

Flood of AI 'garbage' is pushing open-source developers to the limit

A viral cartoon about open-source software shows a teetering pile of boxes labelled “all modern digital infrastructure” and one tiny box right at the bottom, propping up the whole lot: “a project some random person in Nebraska has been thanklessly maintaining since 2003”. That’s the reality of open source: every website, application and operating system relies on it. Modern society couldn’t function without it, and yet it’s written by volunteers in their spare time.

The Speed of Prototyping in the Age of AI

Note: These are personal reflections on how my workflow has shifted over the past year, not a pitch for any tool. Your mileage will (and probably should) vary. A few years back I wrote about my love of throwaway prototypes; those little proof-of-concepts that exist purely to get an idea out of your head and into something tangible.

PlayStation Architecture

Supporting imagery A quick introduction Sony knew that 3D hardware could get very messy to develop for. Thus, their debuting console will keep its design simple and practical… Although this may come at a cost!

Yes! It’s true! Windows 11 is an agentic platform.

In the time zone of the keynote, it's dystopia o'clock. These days, it always is. The fervent CEO prophet strolls around an empty stage, backlit by a giant altar of light on which they display their magic and impart visions of a future that address none of our fears, choosing instead to add to them.

Show HN: Lathe – Use LLMs to learn a new domain, not skip past it

Hey HN!Lathe is an experiment in using LLMs to teach me something new, instead of doing the work for me. It generates a hands-on, source-backed tutorial for any technical topic you want to learn. Then you work through it yourself by reading and typing the code by hand (gasp) in a local UI built for exactly that.

Windows' classic 3D Space Cadet pinball is getting a physical re-creation

Why a Neo Geo port of Doom is functionally impossible

Here at Ars, we've taken pleasure in reporting on versions of Doom that run on everything from wireless earbuds and printers to Windows' notepad.exe and even inside Doom itself. So when we hear that a piece of game-playing hardware from the '90s (or later) can't run Doom, our ears perk up. That hardware is the Neo Geo, an early '90s game console that players of a certain age will remember for its eye-watering launch price and its relatively strong pixel-pushing power for the time.

Rising pop culture star Rachel Pizzolato concludes massive May at Miami Swim Week, Ric Flair's health & MEAT

The sun is shining bright, Monday Screencaps is dialed in, the birds are chirping away, summer is in the air, a skunk unloaded in the early morning hours (thankfully not on my dogs) and it's officially June 2026. Guys, let's face it, this is going to be a massive month for the United States and the world. We have the World Cup, America 250, Trump's birthday UFC event, there's an intriguing NBA Finals (if you're into that sort of thing), the NHL Finals are ready to roll and there's even that...
