Microsoft is releasing the 1976 6502 BASIC code under an open-source license, allowing coders to study and run it in modern systems. The code was originally written by Bill Gates and Paul Allen for the Altair 8800 and later adapted for the Commodore PET and Apple II.
The author's childhood computing experience began in the early 1990s at a school with a computer lab, where they learned to program in LOGO and played classic games like Moon Bugs and Space Invaders. The limited access to computers sparked creativity, leading to writing their own game, Andromeda Invaders, and a lifelong passion for computing.
I used to live on a quiet hill with a great view of the city, but now I live downtown and work with databases. I spent 50 hours drawing a line graph by hand, learning to control line weight and style, and now I appreciate the process and art of hand-drawn data visualization.
Microsoft released source code for the 86-DOS 1.00 kernel and PC-DOS 1.00 kernel, along with utilities like CHKDSK. The code was transcribed from paper printouts by the DOS Disassembly Group, a team of historians and preservationists.
The user has a hard time grasping Scheme due to an inconsistent approach and an ALGOL-based mindset. They want to contribute to the GNU Guix and GNU Shepherd ecosystem but need to overcome their familiarity with other programming languages.
Reasonix is a terminal-based AI coding agent for DeepSeek, engineered for prefix-cache stability. It's a free, MIT-licensed project with a paid DeepSeek API key.

Scammers are abusing Microsoft's system to send fake emails from [email protected], potentially tricking people into thinking they're genuine. Microsoft is investigating and taking action to strengthen its detection and blocking mechanisms.
The user created a 16-byte x86 real-mode DOS assembly program called "wakeup" that uses the video memory as a calculation space to draw an infinite Sierpinski fractal and bangs the speaker with that geometry. The program's sound is created by XORing against the environment, resulting in a unique and sensitive output that is highly dependent on the hardware and BIOS version.
Large Language Model (LLM) agents demonstrate strong performance in autonomous code generation under loose specifications. However, production-grade software requires strict adherence to structural constraints, such as architectural patterns, databases, and object-relational mappings. Existing benchmarks often overlook these non-functional requirements, rewarding functionally correct but ...
A cooperative fiber scheduler for Linux enables high concurrency with low overhead using lightweight stackful coroutines. It includes various features and benchmarks, such as io_uring integration and topology-aware work-stealing, and can be configured and built using CMake.
The Linux kernel's swap subsystem is being improved for better performance and maintainability, with goals to reduce overhead and optimize operations. A new virtual swap layer is proposed to abstract swapping and address issues like defragmentation and migration.
The “dead test” diagnostic cartridge of the commodore 64 uses an 8k ultimax cartridge with rom code at $e000–$ffff. the cartridge implements just 58 characters, without any reverse video characters or reverse image matrices. if we were to address any screen code beyond $39, we’d address the $aa fill area. there are no further character matrixe s implemented and no reverse images of these
Alexander Grothendieck revolutionized 20th-century mathematics with his work in algebraic geometry. He introduced schemes, a new way to study relationships between objects, and reoriented the field in radical new directions.
The user converted an old laptop into a writerdeck, a dedicated writing device, by installing Debian in text mode, replacing the network stack with network-manager, and setting up neovim for writing. They also added features like tmux for terminal tiling, acpi for battery details, and light for backlight control, and set up automatic login and syncthing for syncing notes.
We introduce PICO (Perceptual Image Codec) — the first learned codec that is both practical, and optimized directly for the human visual system. To derive it, we perform a comprehensive study of modeling choices for practical learned codecs, and search over millions of model configurations to jointly optimize over perceptual quality and on-device runtime. Based on large-scale subjective user ...
The HTML <dl> element represents a list of name-value pairs, which is a common UI pattern. It consists of <dt> for names and <dd> for values, allowing for semantic markup and improved accessibility.
The application features a dual editor mode and image uploads, and is deployable via Docker and Docker Compose. It uses Next.js for optimization and can be served with Caddy.
He’d been losing weight — the kind of weight loss that says something’s wrong — and she’d spent weeks trying to reverse it. Cream in his coffee, butter in his soups, all the gristle he could handle. She’d read somewhere that fat was the most calorie-dense food she could give him, and she was right. She’d also read that seed oils were toxic, that the real enemy was vegetable oil, that we were ...
The user changed their desk setup to face the room instead of the wall, creating a more open and comfortable space. They also split their desk into a digital and analog side, allowing for a clear separation of work and personal activities.
P.T. Barnum's book "The Art of Money Getting" offers 20 rules for success, emphasizing finding one's natural abilities and avoiding debt. Key principles include being the best at one's work, keeping income above expenses, and maintaining a good reputation.
User is customizing their i3 and Emacs setup to integrate keybindings and window management. They've modified i3 to pass key events to Emacs if it's focused, and added Emacs functions to send messages back to i3 for window movement and terminal launching.
The user likes keyboards because they're effective and fun, but getting to keyboard mastery can be intimidating due to endless options and confusing software. To achieve keyboard mastery, the user recommends starting with a new keyboard or keypad, customizing it with software, and using tools like Keyboard Maestro to unify shortcuts and automate tasks.
Sales & Dungeons is a free, open-source tool for creating customizable handouts and references for Dungeons and Dragons sessions. It allows users to generate random content and organize sessions with a grid, and is available on GitHub with a community-driven workshop.
The Trump administration requires most foreigners to apply for green cards from their home countries, except in extraordinary circumstances. This change could make it harder for hundreds of thousands of people to obtain permanent residency in the US.
