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.
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 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.
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 author is designing a game engine where skills, supports, items, and runtime rules compose without direct wiring, using a compiler analogy to manage derived caches and behavior changes. The system uses tags, rules, and provenance to manage applicability, avoid stale compiled output, and make it easier to add new content and debug the system.
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.
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.
Bambu Lab, a 3D printer company, is under fire from the open-source community for allegedly violating its own open-source license. The community is rallying behind developer Paweł Jarczak, who was asked to remove his code after he found a way to bypass Bambu's proprietary requirements.
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.

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.
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.
A reproduction of Oliver Byrne’s celebrated work from 1847 plus interactive diagrams, cross references, and posters designed by Nicholas Rougeux Learn about Byrne’s original publication and how this site was made including design, typography, and more. Decorate your walls with a colorful detailed poster of every geometric illustration from Oliver Byrne’s colorful 1847 edition of Euclid’s Elements.
Researchers created a high-resolution digital map of the Roman Empire's roads, revealing a network of 300,000 kilometers, nearly double the previously known total length. The map was created by combining historical datasets with modern topographical maps and satellite data, and it highlights the complexity and extent of the Roman road system.
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.
Union types are a feature in C# 15 that allows representing multiple types in a single variable, and they can be used to handle data that could be one of several unrelated types. The union keyword provides direct support for this scenario, and it can be used with switch expressions to automatically extract the inner case type.
The Spacelab computer was a 16-bit minicomputer built by CIMSA, using a French-built Mitra 125 MS processor. It had a 32-bit ALU and supported up to 128 KB of magnetic core memory.
Air France and Airbus found guilty of manslaughter over 2009 plane crash that killed 228 people. They will appeal the verdict and pay a maximum fine of €225,000 each.
ACAV is an interactive AST visualization tool for C, C++, and Objective-C built with Clang and Qt. It reads a JSON compilation database to explore real project ASTs interactively.
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.

The author reflects on their experience with PHP, a language they initially didn't expect to use, but has grown to appreciate despite its quirks. PHP's array data structure is flexible but complex, and its type system has unintuitive features like uninitialized properties.

To improve deep learning model performance, first identify the bottleneck in your model, which can be compute, memory bandwidth, or overhead. Then, optimize accordingly, such as increasing compute intensity, reducing memory bandwidth costs, or minimizing overhead.
