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.
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 “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
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.
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.
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.
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.
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.
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.
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 author built a tool called Hengefinder to find henge moments, where the sun aligns with a street, by calculating road bearings and sun azimuths. The tool uses a combination of astronomical data and binary search to find these rare geometric alignments.
Pabst Brewing Co has discontinued Schlitz, a Milwaukee-based brand, due to increased costs. Wisconsin Brewing Co will brew the last Schlitz on May 23, with a limited release on June 27.
The user and others extracted microcode from a high-resolution image of the 80386 CPU die, disassembled it, and found 215 entry points with new instructions and shared code. The microcode has a hidden security bug in IO permission bitmap handling and may have undocumented features or opcodes, but the exact nature of these is unclear.
Assuming LLMs will fix code issues is irresponsible, but if organizational leadership mandates leveraging LLMs, we can adapt and move rigor elsewhere. This could involve standardized specifications and tests, checked into project repositories, to ensure accountability and understanding.
