I’ve been working on developing an operating system for the TI-99 for the last 18 months or so. I didn’t intend this—my original plan was to develop enough of the standard C libraries to help with writing cartridge-based and EA5 programs. But that trek led me quickly towards developing an OS. As ...
The user used AI to help port a Linux Wi-Fi driver to FreeBSD, but the process was complicated and messy, so they decided to create a detailed specification of how the driver works and then used the AI to implement it from scratch. The user successfully created a working FreeBSD kernel module for the BCM4350 Wi-Fi chip using the AI, but advises against using it for anything beyond a studying ...
Regulators are pushing social media platforms to verify users' ages, but this creates a technical problem: collecting personal data to prove age. Platforms are using intrusive verification systems that often conflict with data-privacy laws.
The notation $f(x) = g(x) + O(1)$ means the difference between $f(x)$ and $g(x)$ is bounded by a constant. It implies an upper bound, $f(x) \le g(x) + C$, but not a lower bound.
PgDog is a PostgreSQL proxy that supports connection pooling, load balancing, and sharding, written in Rust for high performance and security. It can manage thousands of connections on commodity hardware and supports various deployment methods, including AWS RDS.
Ladybird is rewriting parts in Rust for better safety guarantees and ecosystem support. The first target was LibJS, Ladybird's JavaScript engine, which was translated from C++ in two weeks with zero regressions.
Live capture may require elevated permissions or OS configuration. Babyshark shows Observed IPs using TLS SNI/HTTP Host hints when DNS answers are not visible.
Brian Lucey, a professor at Trinity College Dublin, was removed as editor from 5 journals after 12 papers he co-authored were retracted due to a conflict of interest. Lucey was accused of running a citation cartel and selling papers through his consultancies, which may have been used to circulate ecosystem funds or consultancy payouts.
The author ported Shufflepuck Cafe to the Apple II, a 1979 platform, without losing playability or details. They overcame challenges such as sprite display, mouse handling, and memory limitations.

The user argues that the Web and Internet can be decentralized and controlled by individuals and cooperatives, rather than large corporations, by using simpler software and technologies like Markdown and static website generators. By leveraging the abundance of computers and resources, individuals can create their own private networks and connect to the public Internet, mirroring the concept ...
Researchers are using AI to digitize smell, creating a shared vocabulary and technology to understand and manipulate scent. This could lead to practical applications, such as detecting threats and creating new fragrances, and may help us better understand the mysteries of olfaction.

Flock, a $7.5 billion surveillance startup, allows authorities to track people through its nationwide license plate readers. Communities are pushing back against Flock cameras, with vandalism reported in several states and cities rejecting its use.
The xsync library outperforms other implementations in nearly every scenario with best read, write, and iteration scaling, and lowest allocations among non-sharded designs. However, it has significant performance degradation at sizes ≥100K with writes and limited scalability due to a fixed 32 shards design.
The generalized sequential probability ratio test is a natural extension of the sequential probability ratio test for testing two separate families of composite hypotheses. The test is based on the generalized likelihood ratio statistic and stops when the statistic crosses either of the two boundaries Ln > eA or Ln < e−B.
The Lighthouse film explores the effects of isolation on the mind, with characters experiencing hallucinations and losing grip on reality. Social isolation can be damaging to mental and physical health, leading to hallucinations and erratic behavior.
Femtolisp is a fast, self-contained Scheme dialect with a bytecode compiler and VM, written in the language itself. It prioritizes elegance, simplicity, and reliability with a small core of features and proper tail recursion.
Dijkstra criticized the GO TO statement for inviting program messes, but Scheme programmers can emulate its style using the call/cc procedure. A Scheme macro, goto, can be implemented using call/cc to provide a limited context for jumping around in a program.
Interactive AI timeline tracking 194+ Large Language Models from 2017 to 2026. Explore the history of ChatGPT, GPT-4, Claude, Gemini, LLaMA, Mistral, DeepSeek and every major LLM ever released.
Researchers at Columbia University developed a gel electrolyte to improve anode-free lithium-ion battery safety and longevity. The gel electrolyte prevents dendrite formation, allowing for greater energy density, longer lifetimes, and safer operation in EVs.
Since 2019, my phone has been a OnePlus 5T running LineageOS, and I've loved it. Unfortunately, it uses 3G for calls, and all New Zealand networks plan to turn off their 3G network in early 2026. I would still be able to use this phone for taking photos, playing games, and browsing the web on 4G data, but in theory I wouldn't be able to make or receive calls, because it lacks the ...
The user built a custom family dashboard system called Timeframe, combining calendar, weather, and smart home data, to create a healthy relationship with technology in their home. After several prototypes and iterations, they settled on a real-time e-paper display system using a Boox Mira Pro and Home Assistant as the primary data source.
The EU's "Stop Destroying Videogames" initiative moves to the Commission stage, shifting focus from signature collection to policy work and regulator engagement. A Commission reply is due by July 27, 2026, with potential fallbacks including existing EU consumer law enforcement.
The user analyzed 2,671 images of popular websites worldwide using AI to identify web design patterns and found that Japan's web design is relatively unique in its concentration of lighter-colored and denser design. The user explored possible causes including writing systems, cultural differences, and technology, concluding that Japan's web design trajectory has been influenced by its unique ...
MicroVision aims to produce a solid-state lidar sensor for under $200, a price drop that could make lidar affordable for advanced driver-assistance systems. This move could alter the calculus of autonomous-car design by lowering the cost of precise three-dimensional sensing.
