Framasoft has released the first version of the PeerTube Mobile app for Android and iOS, aimed at enabling wider access to video content while protecting user privacy. Despite developing PeerTube for seven years, Framasoft identifies as a not-for-profit organization focused on educating the public about digital issues and promoting digital emancipation rather than operating as a traditional IT company. This initiative was born out of the desire to create an alternative to platforms like YouTube and Twitch, using limited funding and community contributions.

The content discusses **Ucacher**, a tool designed to automate caching and skipping in GitHub Actions through syscall instrumentation. Ucacher eliminates the need for manual configurations and errors associated with traditional CI/CD workflows, which often require developers to manage cache keys and conditional logic manually. By accurately tracking file dependencies, Ucacher skips redundant steps and restores outputs, resulting in a speed increase—specifically, a 2x speedup was observed in tests on the React repository. The post contrasts Ucacher

Irina Nazarova and Travis Turner of Evil Martians discuss their focus on supporting startups using Ruby on Rails, highlighting both the advantages and challenges faced by these teams, particularly in frontend development. They emphasize that while Ruby and Rails enhance productivity and provide a competitive edge, frontend issues remain a significant hurdle. The authors introduce a “silver toolkit” designed to improve frontend productivity, encapsulated in the phrase “Cooling down Hot Wires with Inertia.” This phrase serves as a concise representation of their findings and

Steve Jobs referred to computers as a “bicycle for the mind,” highlighting how technology enhances human capabilities. Advanced AI coding assistants like ChatGPT may represent a more sophisticated tool, akin to a "self-driving car for the mind." However, the $200 monthly fee for such tools may seem high for individual developers, many of whom believe current AI capabilities do not justify the cost. Yet, as professionals in various fields adopt AI assistants at similar price points, there is an increasing willingness to pay. The

In Ruby on Rails, ActiveRecord helps manage databases, with `where.not` being a traditional method to filter out records based on conditions. However, the newer `excluding` method offers a more efficient alternative for excluding specific columns from queries. While `where.not` can exclude records (e.g., fetching all users except those with a particular email), it doesn't work for column exclusion and can lead to cumbersome queries. On the other hand, `excluding` allows for straightforward exclusion of specific fields, like

The article discusses common misconceptions about compilers, particularly large-scale general-purpose compilers like LLVM, GCC, and ICX. It clarifies that the perception of compilers performing optimally is misleading; they do not seek to find the perfect program but rather aim to improve upon a simplified version of the original code. The term “optimization” can be misleading, as it implies a pursuit of an ideal solution, which is difficult and time-consuming. The author notes that while compilers target various metrics

The 2019 paper titled "Quantum supremacy using a programmable superconducting processor" claimed that Google's Sycamore quantum computer, utilizing 53 qubits and a depth of 20, executed a specific computation in roughly 200 seconds, whereas a classical supercomputer would allegedly take about 10,000 years for the same task. However, there are significant doubts regarding these claims that may stem from methodological errors rather than objective findings. The criticisms are centered around two main points: 1. **Flawed

The content discusses a minimalistic ahead-of-time Ruby compiler called Lightstorm, which targets C instead of machine code. It emphasizes the importance of user feedback and provides a link to additional documentation. Lightstorm can significantly improve code execution speed, with an example showing a nearly 30% reduction in execution time for the aobench benchmark. Users can set up the compiler using either a codespace or a devcontainer, with specific instructions for macOS and Ubuntu, including requirements for Ninja, CMake (

The author argues against the practice of naming scientific and mathematical discoveries after their creators, advocating instead for names that convey the essence of the concepts. Recognizing contributors through awards is sufficient, while informative names help users understand and communicate ideas effectively. The author cites examples like "breadth-first search" and "Gaussian distribution," which are descriptive, compared to less informative names like "Dirichlet distribution." They emphasize that knowledge should be built upon compositional understanding, where core concepts can be combined meaningfully,

The content, authored by Kevin Bourrillion, discusses the complexities programmers face when dealing with dates and times in their code. Despite the fact that we learn about these concepts early in life, programming requires a much higher degree of precision and correctness, leading to frequent bugs and confusion. The Java and Kotlin Ecosystem team at Google has spent years working to minimize date/time-related errors in their codebase and has gained valuable insights from this experience. Instead of offering a list of programming practices, the author intends

The author reflects on the evolution of the C programming language, particularly its portability issues in the early days of "K&R C". They recount their experiences with different systems, such as the Radio Shack Color Computer and the Commodore Amiga, highlighting the challenges of varying "int" sizes between architectures—16-bit on one and potentially 32-bit on another. After starting a job at Microware in 1995, they encountered the ANSI-C compiler and the need for specific type definitions to address

A viral tweet has emerged claiming that 9.5% of engineers are "ghost engineers," who barely contribute to work yet earn significantly through multiple jobs. While the claim has gained traction, supported by research attributed to Stanford and various news outlets, the original methodology has not been peer-reviewed, raising concerns about its validity. The author of the research lacks a background in software engineering, which questions the reliability of their conclusions about productivity and credibility in the field. The blog post emphasizes the need for skepticism towards

U.S. fourth and eighth graders experienced significant declines in math scores between 2019 and 2023 on the Trends in International Mathematics and Science Study (TIMSS), a test assessing foundational math and science skills among students in 64 countries. While American fourth graders' scores dropped steeply, the declines were more pronounced among lower-performing students, a trend that predates the pandemic. Despite the declines, U.S. students remain in the middle tier internationally. Leading countries in the rankings include Singapore,

The content discusses the benefits of Immutable Arrays, highlighting their safer and more efficient nature compared to read-only lists. These arrays achieve true immutability while offering performance and memory optimizations. They compile as regular arrays in bytecode but lack mutating capabilities. Immutable Arrays are especially suitable for memory-constrained and performance-critical applications, such as those in Android and JVM environments. Performance benchmarks, conducted using the Java Microbenchmark Harness, involve 1,000 collections with various sizes based on a realistic probability distribution
