We have seen in a previous post that switch statements are more complex than they seem. The compiler is able to implement them as a decision tree (even though maybe it shouldn't). Is that everything it can do? In this post, I'll focus on gcc. All optimizations, except the bitset lowering, translate to clang. I'll be using the -O3 optimization flag unless indicated otherwise. Let ...

Major media outlets are advocating for the Stealth Bot Prohibition Act, which would require website accessors to identify themselves and their purposes. The bill threatens legitimate public-interest activities like investigative journalism and data collection that rely on automated tools.
SAMOSA checks every step of your matrix derivation, exactly, over finite fields. A 2x2 counterexample and a fix, in your browser. No AI in the verdict.
Nesformer is a model that simulates the NES console's 6502 CPU and cartridge, predicting its execution log one token at a time. It uses Qwen3_5ForCausalLM weights compiled from CHIP-8 and RISC-V CPUs.
Archaeologists in Norway have recovered 48 prehistoric arrows from melting ice, dating back 5,000-6,000 years. The finds highlight the impact of climate change on preserving ancient artifacts.
This is a Star Trek: The Next Generation episode guessing game where users can guess episodes based on images, with feedback provided even if the season is incorrect. User data may be tracked and stored for analytics purposes.
The author created a LaTeX package called "florilegium" to generate floral ornaments in the style of 18th-century botanical illustrations. The package uses Lua to procedurally generate flowers, leaves, and stems based on parameters such as seed values and page layout.
The WireGuard state machine implementation, sanstun, is a sans-IO Rust library that optimizes for ease of use, security and performance. It separates IO and side-effects from the state and business logic to enable parallel-friendly API design.
Infinite Mac now offers BeOS versions, a multimedia-focused OS that impressed Apple and was ported to Power Macintoshes in the mid-90s. The site's emulator, DingusPPC, has been improved for BeOS compatibility.
Phorion has discovered a backdoor in the Claude Code for VSCode extension bundle that drops a persistent SSH backdoor across macOS, Linux, and Windows. The malware sets up an outbound SSH connection to 134.209.82[.]225 on port 22 and sends a beacon back to the attacker's server with host reconnaissance information.
Tangled is a new, federated code forge that allows users to host their own code and collaborate with others while maintaining control over their infrastructure. It offers the longevity of an open protocol with the convenience of a proper forge, featuring self-hosting options and customizability.
The PDP series of computers, developed by Digital Equipment Corporation (DEC), were designed for industrial control systems and later became popular among hackers due to their affordability and flexibility. The smaller machines like PDP-4, 5, 6, 7, and 10 influenced the development of Unix and other programming languages like Lisp and Scheme.
Jules Verne imagined Paris in 1960, a century ahead, to see what civilization the 19th century might become with its faith in science and efficiency. His book "Paris in the Twentieth Century" was initially refused by his publisher due to its bleak tone and implausible prophecy.
Cisco's president, Jeetu Patel, is hiring young workers to challenge the status quo and bring fresh ideas to his company. He believes that Gen Zers with little experience can teach veterans how to think differently and drive innovation.
The author has discovered multiple vulnerabilities in Azure's API Connections, a part of Azure Logic Apps, allowing attackers to compromise any connected backend service worldwide. These vulnerabilities netted the author $200,000 and were reported to Microsoft.
A double-buffered queue is used to segment telemetry events by UTC hour, leveraging Cloudflare Workers and R2 for efficient processing and storage. This pattern transforms chaotic streams into a compressed hourly archive, optimizing cloud storage bills.
The author reflects on their experience working with early-stage startups, particularly Runa and Factual, where they struggled to balance technical innovation with business needs. They learned that most startups fail due to stagnation rather than growth challenges.
Patrick Stewart's portrayal of Captain Jean-Luc Picard has left a lasting impact on fans, particularly for those who grew up watching Star Trek: The Next Generation. His nuanced and emotionally truthful performance as the character continues to resonate with audiences today.
Leaders are evaluating engineering managers for AI skills by considering questions like what tools and processes they use to optimize software shipping. Engineers at FurtherAI have built an AI-native org, increasing code changes per day 5x while reducing revert rate, with a focus on automating tasks and empowering engineers to make decisions.
A US-based startup, 247Solar, is building a small concentrated solar plant in India that can also use fossil fuels as backup power. The system combines solar thermal and photovoltaic generation to provide around-the-clock renewable energy without the need for separate facilities.
Researchers introduced a "sleep framework" for large language models, allowing them to continually learn and adapt without catastrophic forgetting. This framework enables models to retain short-term memories, abstract new skills into long-term parameter structures, and continuously self-improve through active learning and offline rest phases.
Knock On Wood is an internet-connected device that simulates knocking on wood remotely through a web app, part of the Machines Responding to Superstitions series. Users can trigger devices worldwide using only a web browser and Wi-Fi connection.
Harvard astrophysicist Shep Doeleman and his team used a network of radio telescopes around the world to capture the first-ever image of a black hole, located 55 million light-years away in galaxy M87. The Event Horizon Telescope project, which took over two decades to complete, has opened up new possibilities for studying supermassive black holes and their role in shaping galaxies.
