In the blog post by Loris Cro, the author discusses the concepts of concurrency, parallelism, and introduces the term "asynchrony" as a missing piece in understanding concurrent programming. Concurrency allows multiple tasks to be executed either simultaneously or through time-sharing, while parallel computing involves doing many calculations at the same time. The author explains that asynchrony plays a crucial role in concurrent programming. Using examples like saving files and creating a TCP server, Cro illustrates that in some cases, the

Economists identify two key roles of advertising in enhancing welfare, but the internet has disrupted these roles. Instant search capabilities have weakened the effectiveness of ads by fostering a "grifter equilibrium," where marketplace dynamics allow for low-quality sellers to thrive. For instance, when searching for "ankle socks" on Amazon, different types of sellers face distinct profit structures. High-quality sellers earn profits without returns or relaunch costs, while low-quality sellers incur penalties for poor quality and face potential relaunch costs.

The content discusses the author's efforts in recovering data from GameCube Memory Cards and SD Cards used in the Nintendo factory setup for the Wii and Wii U. After Nintendo attempted to destroy these cards, about 50% were damaged beyond recovery, 25% were salvageable with some repair, and the final 25% required extensive work, including soldering. The work was described as labor-intensive but important, resulting in the recovery of previously unseen data. Additionally, the author mentions the discovery of a new

MR Browser is a utility app designed for older Macs from the 1990s that can connect to the internet but cannot run modern web browsers. It allows users to access the Macintosh Repository online services and download files directly, limited to those smaller than 1GB. Users must ensure sufficient free hard drive space to prevent crashes when downloading files. For troubleshooting, users should download MR Browser using the link provided specifically for old Macs, as modern browsers may flag it as unsafe. Common issues include a "Runtime

The article discusses the development of Rust bindings within the Linux kernel, highlighting the evolution of interfaces between C and Rust. It emphasizes that non-trivial Rust drivers require various bindings for tasks such as memory allocation and locking. While Rust can use the foreign function interface (FFI) to call C functions, direct integration poses challenges due to differences in memory management and locking conventions between the two languages. Initially, the project aimed to establish a centralized set of Rust bindings for each kernel subsystem, which, while

Debian packaging is often seen as challenging, causing many new contributors to give up and seasoned ones to experience burnout due to tedious maintenance tasks. Debcraft aims to address these issues by automating repetitive tasks, facilitating learning of best practices, and improving the tracking of changes in source code and build artifacts. Unlike other package formats like RPM or APK, Debian packages use multiple declarative files in the debian/ subdirectory rather than a single script. This approach enhances robustness and allows for static analysis without needing

Valve recently announced the removal of several adult games from its Steam storefront due to concerns from payment processors like Mastercard and Visa. The company stated that these games may violate the rules set by these processors, which, according to Valve, is essential to prevent the loss of payment options for customers purchasing other titles. While Valve is reaching out to affected developers and offering app credits for future games, the lack of specific game titles removed highlights the impact of payment processor policies on content availability. Valve appears to be constrained by

The AMD RDNA™ 4 architecture introduces GPUs featuring 3rd-generation Matrix Cores that enhance the performance of Generalized Matrix Multiplication (GEMM) operations. A comparison of theoretical FLOPS per clock per compute unit (CU) shows improvements over previous generations, but the architecture has altered the VGPR layout for Wave Matrix Multiply Accumulate (WMMA) operations, leading to a lack of backward compatibility. To accelerate GEMM operations on RDNA 4 GPUs, developers must utilize

In Vidar's blog, the concept of "dynamic programming" is clarified by emphasizing that the term "programming" refers to planning and organization, rather than computer programming as it is commonly understood. The origin of the term dates back to the 1950s, when civil engineers used it to denote the planning of projects, such as constructing office buildings. This required steps to be ordered based on dependencies, ensuring that each task relies on the completion of prior tasks. Similarly, in computer science,
