DeepGEMM: Clean and Efficient FP8 GEMM Kernels with Fine-Grained Scaling

DeepGEMM is a library for clean and efficient FP8 General Matrix Multiplications (GEMMs) on NVIDIA Hopper Tensor Cores, featuring fine-grained scaling as proposed in DeepSeek-V3. Supporting both normal and Mix-of-Experts (MoE) grouped GEMMs, it uses a lightweight Just-In-Time (JIT) compiler, eliminating the need for compilation during installation. It tackles the imprecision of FP8 tensor core accumulation via CUDA-core two-level accumulation (promotion). Despite its concise design (~300 lines of core code), DeepGEMM's performance matches or surpasses expert-tuned libraries across various matrix shapes.

Hamburger Menus: A Decade Later, Are They Still Usable?

A decade on, the hamburger menu is a ubiquitous navigation pattern. However, the old problems of hidden navigation persist: users overlook it, leading to increased task completion times and decreased satisfaction. While user recognition of the hamburger menu has improved, design risks remain. This article revisits early research findings, shares new research on hamburger menu recognizability, and offers visual design best practices for the hamburger icon. Research shows that the standard three-line icon, top-left placement, and clear labels improve hamburger menu usability. But the article cautions that hidden navigation always adds interaction cost and visible navigation should always be prioritized. Use them wisely, follow best practices, and always test with users.

Shapecatcher: Find Unicode Characters by Drawing!

2025-01-18

Shapecatcher is an innovative tool that lets you find Unicode characters by drawing their shape. Currently boasting 11817 glyphs, it's a convenient solution for finding characters whose names you don't know. Simply draw the character, click 'Recognize', and Shapecatcher will find the closest match. While Japanese, Korean, and Chinese characters aren't yet supported (due to font licensing), future updates plan to integrate the high-quality Noto font to address this. The project is still in beta.

Slashing CI Time with AI-Powered E2E Test Selection

End-to-end (E2E) tests are slow, fragile, and expensive, often run nightly due to CI bottlenecks. This leads to bugs slipping into production. This article details a solution using Claude Code to intelligently select only the relevant E2E tests for a given PR. By analyzing code changes and test files, Claude Code predicts which tests need to run, reducing testing time from 44 minutes to under 7 minutes. This significantly improves CI efficiency and prevents production bugs. While slightly costly, the savings in developer time and bug fixes make it a cost-effective solution.

Lisp Dialect Showdown: Scheme, Common Lisp, Clojure, and Racket

2025-03-07

The Lisp family is vast and complex. This post explores four prominent dialects: Scheme, Common Lisp, Clojure, and Racket. Scheme is known for its minimalism and strong academic foundation; Common Lisp boasts a rich standard library and decades of history; Clojure emphasizes functional programming, concurrency, and JVM interop; and Racket is beginner-friendly with a focus on education and extensibility. The article delves into each dialect's history, community, and unique characteristics, offering a humorous take on the inter-dialect 'tribalism'. Ultimately, it avoids declaring a 'best' dialect, instead guiding readers to choose the Lisp that best suits their needs.

Vestigial Ear Muscles Activate During Effortful Listening

Vestigial Ear Muscles Activate During Effortful Listening

A new study reveals that human auricular muscles, once used to move our ears, reactivate during challenging listening tasks. Scientists used electromyography to measure muscle activity while participants listened to audiobooks with competing sounds. The results showed increased activity in the superior auricular muscles when hearing was difficult, suggesting these vestigial muscles may play a role in attentional mechanisms. While the muscle movements are minuscule and likely don't improve hearing, their activation could serve as an objective measure of listening effort.

C's `defer` Keyword: A Blitz to Prevent Memory Leaks

A new feature is coming to C: `defer`. It acts as a general-purpose 'undo' mechanism, ensuring that a set of statements are executed regardless of how a code block exits, crucial for resource cleanup like freeing memory or unlocking mutexes. `defer` builds upon existing compiler extensions and similar features in other languages. The article details `defer`'s functionality, scope, and differences from similar constructs in Go, with examples illustrating its use. The author urges compiler vendors to implement `defer` promptly to enhance C code safety and maintainability, preventing memory leaks like those seen in CVE-2021-3744.

Generative AI is Eating Away at OSINT Analysts' Critical Thinking

2025-04-03

The increasing reliance on generative AI tools in OSINT (Open Source Intelligence) investigations is leading to a decline in critical thinking among analysts. Studies show that over-reliance on AI reduces critical thinking, making users more susceptible to accepting AI-generated misinformation. Real-world scenarios illustrate the potential dangers of AI in OSINT, highlighting the vital need for manual verification. The article urges OSINT practitioners to prioritize critical thinking, treating AI as a supplementary tool rather than the decision-maker. It advocates for intentionally introducing friction to avoid over-dependence on AI, thus preserving accuracy and integrity in OSINT.

The 1561 Nuremberg Celestial Event: UFOs or Atmospheric Phenomena?

On April 14, 1561, a mass sighting of unusual celestial phenomena occurred over Nuremberg. A woodcut broadsheet depicts hundreds of spheres, cylinders, and other objects engaging in what appeared to be an aerial battle. While some interpret this as evidence of extraterrestrial spacecraft, skeptics attribute the event to atmospheric phenomena like sun dogs. Carl Jung offered a perspective suggesting a natural event overlaid with religious and military interpretations, leaving the true nature of the 1561 Nuremberg event a subject of ongoing debate.

X Platform Bans Signal.me Links: A Blow to Privacy?

Elon Musk's X platform (formerly Twitter) has recently banned links to Signal's "Signal.me" URL, preventing users from posting them in DMs, public posts, or even their profile bios. This move raises concerns, as Signal, with its end-to-end encryption and privacy focus, is a crucial communication tool for journalists and whistleblowers, particularly relevant amidst recent US government data leak controversies. While users can still share their Signal usernames manually, this added friction impacts communication and potentially threatens information security and press freedom. The ban signals a further tightening of information control on X, with the motivations remaining unclear.
