Researchers at Germany’s Helmholtz-Zentrum Berlin (HZB) have successfully examined an antique Buddhist scroll from Mongolian nomads using 3D X-ray tomography and AI, avoiding physical damage to the delicate artifact. The scroll, known as a dharani, is a small prayer scroll traditionally carried by nomadic families. This particular scroll and its accompanying shrine are part of a collection that survived the tumultuous period of the Soviet-backed Mongolian Revolution in 1921, which led to the destruction

Apple's new Processor Trace instrument in Xcode addresses common performance issues developers face, such as user complaints about slow apps or battery drain. Unlike traditional profilers like Time Profiler that offer statistical sampling, Processor Trace captures every branching decision made by the code at the CPU level, providing a clear view of the app's execution flow. This tool offers a more comprehensive analysis than Intel's VTune Profiler, which, while advanced, is complex and not optimized for iOS or macOS development, especially

Dyna is a programming language specifically designed for machine learning researchers, building on the concepts of logic programming languages like Datalog and Prolog. It enables flexible execution orders and allows rules within programs to be weighted, which facilitates the expression of complex programs succinctly. For instance, operations such as matrix multiplication and the Fibonacci sequence can be written in just a line of code. Launched in 2004, the Dyna project aims to bridge the gap between non-executable mathematical notation and executable code

The article discusses the performance of the MurmurHash64A hash function, particularly focusing on its assembly code and optimization opportunities. It notes that while the function itself is effective, there are inefficiencies in how certain operations, like `memcpy`, are handled in different compilers (LLVM and GCC). The author points out that the assembly code generated by LLVM has multiple unnecessary operations that could be streamlined. For instance, it could inline `memcpy` and reduce redundant loads of constants. The article

The author expresses frustration with the current vocabulary and classification for software testing, arguing that terms such as "unit test" and "integration test" lack clear definitions. The actual behaviors being tested and the methodologies used in end-to-end (E2E) tests are often underspecified, and other types of tests—like stress and load tests—lack a proper framework. The author advocates for a more actionable vocabulary that allows testers to adapt their approaches based on resources. They propose a categorization of tests into

Graceful degradation is a design principle in software applications that allows systems to maintain essential functionality even during failures or heavy traffic. Instead of crashing, a system operates at reduced capacity. For instance, a video streaming service might display a general list of popular videos if its recommendation engine fails, ensuring that video playback continues. Implementing graceful degradation involves strategies like traffic control, failure management, and system health visibility. Rate limiting or request throttling acts like a bouncer, managing incoming requests during high traffic events to

In a 2013 blog post by David on Randomwire, he examined the distinctive nature of Japanese web design, contrasting Japan's international reputation for minimalism with its actual online presence, which is characterized by maximalism. Japanese websites often feature vibrant colors, dense text, and numerous images, diverging from the three-color design principle prevalent in other cultures. To investigate this phenomenon further, the author analyzed 2,671 images from popular websites worldwide using AI, revealing distinct web design clusters. Not

The project discusses the mathematical approach to dicing onions, motivated by widespread curiosity about the topic on platforms like YouTube. Chef J. Kenji López-Alt explored optimal methods for achieving uniform piece sizes in onion dicing. The article describes starting with a halved onion and analyzing the effects of vertical cuts on piece size consistency, using the concept of standard deviation to measure variations in piece sizes. Specifically, it focuses on relative standard deviation, allowing for unitless comparisons of how closely the sizes cluster around

A Pfeilstorch (German for 'arrow stork') is a white stork that returns to Europe with an arrow or spear embedded in its body after wintering in Africa. Approximately 25 such storks have been documented in Germany as of 2003. The first notable Pfeilstorch, found in 1822 near Klütz, Mecklenburg-Vorpommern, carried a 75-centimeter spear in its neck and is on display at the University of Rostock. This stork was

The content discusses a personal project aimed at creating minimal implementations of notable static type systems over the last 50 years. The project involves developing toy versions of programming languages and core type-checking algorithms, starting from simpler systems and advancing to modern dependent types. The implementations will be done in Rust due to its good parser ecosystem and ease of installation, alongside a preference for the contrast between functional languages and a non-functional programming language. This project is intended as a fun side activity, rather than a rigorous introduction to
