Aluminum (Al) alloys are commonly used in aerospace and automotive industries. Selective laser melting (SLM) is used to create complex parts with design flexibility. Most studies focus on medium-strength Al-Si and Al-Si-Mg alloys suitable for 3D printing. High-strength Al alloys like AA 6061 and AA 7075 can suffer hot cracking during manufacturing, but adding fine […]

On the cr.yp.to blog, the post “Clang vs. Clang: You’re making Clang angry” discusses the issue of compiler “optimizations” leading to bugs and security risks. Compiler writers shift blame to language standards rather than taking responsibility. Cryptographers face challenges with compilers introducing leaks, impacting security. Benchmarking shows AVX2 implementation surpasses compiler “optimizations” in performance. The […]
Programmers often reference “Turing-completeness” on the internet, with some domains valuing not being Turing-complete. The author argues that discussions misunderstand the term, highlighting its precise meaning and importance. The piece delves into theoretical results about computation, explaining key concepts like primitive recursive functions and Turing Machines. Part of the content explores Finite State Machines and […]
Simon Burkhardt explains the concept and functionality of FPGAs, a unique form of high-performance chip for niche applications. Few people understand FPGAs, much less know how they work or what their internal architecture looks like. Inspired by Ben Eaters’ 8-bit CPU on a breadboard, Burkhardt built his own simple FPGA in hardware. He goes into […]
The author delves into the origins of celebrating World Wide Web Day on August 1st by exploring Tim Berner-Lee’s original WorldWideWeb application code for NeXT. The author copies the code to a GitHub repository to browse it more easily using syntax highlighting. They go on to explain how to back-date Git commits by setting environment […]
The author reminisces about their time working with the best and worst codebase they ever encountered in their career. They recall the challenges and quirky solutions within the system, such as creating a table with only one column to generate IDs and using a manual calendar table to restrict logins. The database was a chaotic […]
In the medieval period, there was another ‘New England’ located far to the east of the modern-day England, in the area of the Crimean peninsula. This colony was established by Anglo-Saxon exiles after the Norman Conquest of 1066 and seemed to have survived until at least the thirteenth century. These exiles entered the Varangian Guard, […]
Redox has been selected for an NGI Zero grant, focusing on implementing POSIX signal handling and process management in userspace. This will allow for significant improvements to the Redox kernel performance. An updated scheme packet format and new syscalls have boosted RedoxFS copy performance by 63%. The kernel is undergoing changes to handle SYS_PREAD2 and […]
