The user used AI to solve the problem of constructing abnormal magic hexagons, a long-standing open problem in mathematics, by imposing additional symmetry constraints and using a potential field representation to reduce the search space. The AI, GPT-5.6 Sol, was able to find a constructive proof for the existence of abnormal magic hexagons for every order n > 3, and the user was able to ...

os8088 is a hobby project that recreates a Macintosh System 1-style desktop for the Intel 8086, featuring overlapping windows, pull-down menus, and pre-emptive multitasking. It boots from a floppy and runs entirely in real-mode assembly, with a 40KB kernel and a graphical interface that fits in 256K of RAM on an Intel 8086 or 8088 processor.
The user discusses optimizing A* pathfinding by improving the heuristic function, specifically using landmarks to guide the search towards the goal. Landmarks can be used to create a lower bound for the path length, and multiple landmarks can be used to cover more of the map, but their placement depends on the start point, goal, and map layout.
[Editor's note: This article was originally scheduled for publication in the September 1998 issue of BYTE Magazine but was canceled when BYTE folded in June 1998. It appeared instead in Windows NT Magazine and in C'T, a German computer magazine.

Shopify used SKIP LOCKED, composite primary keys, and connection visibility to handle high-throughput inventory reservations during peak traffic. The solution eliminated overselling and underselling issues, improved database health, and allowed Shopify to meet its scale targets on Black Friday 2025.
Fastmail now offers data storage in the European Union, specifically in Amsterdam, in addition to its US locations. You can choose your region and primary data storage location, with encrypted backups in Philadelphia.
A QR code is a grid of squares that encodes data, with function patterns for easy scanning and data modules for storing information. By modifying data modules, QR codes can be made to look distinctive, but may be less robust when scanning.
The Port of Long Beach in Southern California uses geocells, a 3D structure made of plastic strips, to improve bearing capacity and prevent washboarding on unpaved roadways. Geocells can significantly reduce the thickness of a base layer needed for road construction, make it possible to use cheaper base materials, and provide a net environmental benefit by reducing excavation and haul distance.
Tim Berners-Lee's "Cool URIs don't change" is challenged by link rot, where web documents often disappear over time. A bet on longbets.org/601 aims to prove a site can survive 11 years with a stable URI system.
To achieve a stylized look in 3D rendering, the user proposes a mixed approach called "Stylized GGX Shading" that combines PBR and toon shading. This approach involves modifying the GGX Cook-Torrance microfacet model to create a more stylized look with big sharp highlights at low roughness and soft gradients at high roughness.
for-sale is a DNS leaf node name signaling a domain is available for purchase, defined by RFC 10023 and registered with IANA. It's not a parking service, but a way for brokers and automated services to check domain availability without disrupting the site.
Unexpected events, such as a person dressed as Batman, can increase prosocial behavior by disrupting routine and enhancing attention to the present moment. This study found that passengers on a Milan metro were more likely to offer their seat to a pregnant woman when Batman was present, suggesting that novel and unexpected events can promote kindness in public settings.
I’d come because I was curious about what drives someone to live in a swamp. The flat-bottomed boat nosed through the murky water like an alligator. At the tiller, Keith steered with the confidence of a man who’d run these channels since boyhood, his camouflage style and mirrored sunglasses screaming summer of ’87. Tara sat up front, loose strands of blonde hair breaking free from her braid ...
Game developers should aim to create a smooth difficulty curve by introducing new mechanics and challenges gradually, allowing players to feel a sense of progression and accomplishment. To achieve this, developers can use various techniques such as providing subtle hints, allowing players to grind for experience, and hiding shortcuts that require knowledge to access, all while monitoring ...
Interactive map of the August 12, 2026 total solar eclipse. Precise timings, path of totality, weather odds and viewing tips for any location.
Each card opens the packet: what has been proved, which routes failed, and the code behind every computation. determine the exact number of initial sets whose closure is the entire board. for every (varepsilonin(0,1)), does there exist a constant such that, for each integer nge2, every finite-dimensional real banach space xdim xdelta(
Donald Unger cracked his left knuckles for 50 years to prove arthritis warnings wrong, but found no difference in his hands. Studies show knuckle cracking is mostly harmless, but excessive neck cracking can cause serious injury.
The author of Daring Fireball retracted an article about an App Store rejection due to incorrect information. The article was about Terry Godier's astrology app "Asterly" being rejected, but Godier had actually submitted an astronomy app under the same name.
SAP suspended most travel and hiring due to AI's soaring cost, with exceptions for AI-related activities. The company is rolling out a new AI tool, which may further increase costs, according to an internal email.
MySpace, a social network from the early 2000s, is rumored to be making a comeback. Its original strengths, such as music and personal expression, could still resonate if the platform is redesigned to be more accessible and user-friendly.
A team of students at the 12Urenloop in Ghent, Belgium, experimented with using UltraWideBand (UWB) technology to track runners' positions in real-time, achieving accurate measurements and a high measurement rate. The team successfully tested the system on a corner of the circuit and plans to integrate it into the existing batons and improve its reliability for future use.
We introduced Neptune, a Direct3D protocol layer, to improve Wine game performance on Linux guests. We've now achieved full DirectX 11 support in QEMU virtual machines with a new Windows driver called Triton and Neptune.
Assertions are a crucial tool for ensuring software correctness and safety, but their usage can be confusing and underpowered in many implementations. By defining when and where to use assertions, developers can effectively leverage them to cover correctness, safety, development, and documentation aspects of their code, leading to better code quality and easier debugging.
The user created a video about web platform features and accessibility, but initially made a mistake by removing aria-label from a button, causing screen readers to announce incorrect information. They corrected the mistake by switching to aria-labelledby, which provides the button with an accessible name.
