The author discusses improvements to JRuby startup times using features from recent JDK versions, particularly focusing on Application Class Data Sharing (AppCDS) and the upcoming AOTCache feature in JDK 24. Initially introduced with Java 1.7/1.8, CDS allows for pre-loading runtime metadata to speed up JVM applications. While AppCDS has been cumbersome in JRuby, recent JDK updates, especially JDK 21, have made generating and using AppCDS archives more

Neva is an innovative programming language that utilizes a network-based approach, allowing data to flow between nodes with immutable messages and running in parallel by default. After type-checking, it compiles to machine code that can be shared as a single executable with no dependencies. Neva is particularly strong in stream processing and concurrency while maintaining simplicity for developers. Upcoming updates will introduce visual programming and interoperability with Go for easier adoption. The latest release has added a new 'errors' package to the standard library, including

The project aimed to utilize two cameras and various methods for detecting and tracking objects in videos to create a 3D representation, facilitating analysis of volleyball games. This endeavor was driven by the author's passion for volleyball, despite lacking skills in the sport. Challenges included a flimsy stand that affected video alignment; a recommended solution was using quick movements, like blinking, to sync frames. The author also provided commands for ensuring videos have the same frame rate. For body detection, the RTMO library was preferred for

This guide explains how to debug a Ruby microservice in a Kubernetes environment using mirrord, a tool that simplifies local debugging with Kubernetes contexts without the need for continuous building and deploying. Debugging microservices on Kubernetes can be challenging due to various runtime dependencies and resource-intensive processes, such as building and deploying container images for testing. Common debugging methods include log analysis and using remote debugging tools in IDEs like RubyMine, but these can be cumbersome and affect performance. Mirrord offers a more efficient

The content discusses integrating event tracking using the Hotwire stack and a Stimulus controller. It highlights the typical use of GET and POST requests for HTML responses but notes the need for custom requests, such as capturing video player events. The JavaScript Fetch API is introduced for sending event data to a server endpoint. The process is simplified using the @rails/request.js library, which manages required headers for Rails apps. To enhance reusability, the code for event tracking is refactored into a separate function

The author, who now works with Haskell, aims to refresh their knowledge of the Yesod web framework by creating a personal project called Fisher's Fountain. This project is suited for a brief hack since it doesn't require interaction with external collaborators but offers more than static content. Historically, the author has avoided maintaining deployments for side projects due to the desire to limit their monitoring responsibilities. Fisher’s Fountain, however, introduces a need for uptime monitoring of a separate server process, although it's built as a

The article discusses the frustrations associated with using JSON and YAML for configuration data, commonly utilized in contexts like Kubernetes, APIs, and cloud infrastructure. While JSON is machine-friendly, it's often perceived as verbose and cumbersome for human users. YAML, while more flexible, poses challenges in mechanical parsing due to its reliance on whitespace. Both formats have drawbacks, leading to difficulties in writing and maintaining configuration files. The author advocates for a better solution that addresses the shortcomings of JSON and YAML, proposing a more user-friendly format

The essay argues that the integration of AI models into developers' workflows has hindered the adoption of newer technologies due to limitations in training data and the influence of system prompts. It highlights a bias towards certain technologies facilitated by AI's assistance, as developers increasingly prioritize the availability of AI support when making technology choices. The author explains that large language models often become outdated by the time they are trained and deployed, creating an "AI knowledge gap" that limits their effectiveness in helping users adopt emerging technologies. This gap

In February 2025, Roni Carta reflects on his journey in offensive security, particularly in Bug Bounty Hunting, where he identifies and reports vulnerabilities to earn monetary rewards. Initially struggling to identify critical vulnerabilities, his skills improved significantly through collaboration with Snorlhax, a competitor on the HackerOne French Leaderboard. Together, they focused on a specific bug bounty program, successfully discovering multiple high-value vulnerabilities, each worth $10,000. They transitioned from competition to collaboration, identifying various bugs such

YouTube, established in 2005, has evolved from a video-dating site into a major media platform with billions of daily users. Recently, to celebrate its 20th anniversary, YouTube updated its brand palette, introducing a softer shade of red and a new magenta gradient in key features like the video progress bar. Members of the art direction and design teams explained that the change was meant to keep the brand feeling fresh while respecting its iconic identity. They emphasized the importance of color in branding

The content discusses why cryptography does not rely on NP-complete problems, emphasizing that cryptographic schemes are based on the computational difficulty of specific 'hard' problems rather than NP-completeness. For example, RSA encryption is based on the difficulty of factoring the product of two large prime numbers. The security of RSA relies on the assumption that it would require an impractical number of operations (greater than \(2^{128}\)) to solve the problem, making it hard for randomly chosen instances.

In a recent discussion, Aaron Patterson addressed the need for a faster Foreign Function Interface (FFI) for CRuby, acknowledging that although Ruby programming is preferred, there are times when native code is necessary. He advocates for creating native extensions that keep the API minimal, allowing the majority of processing to occur in Ruby to benefit from optimizations provided by YJIT. This involves using native code as a thin wrapper for conversion between Ruby and native types. Patterson expressed his general reluctance towards F

The content discusses a performance benchmarking graph that tracks over 1,000,000 CPUs. This graph shows year-on-year performance data based on thousands of results from PerformanceTest versions V5 to V11, updated bi-weekly. PerformanceTest V8, released in 2012, was notable for being the first version to collect single-thread performance data. Users can compare the performance of up to five different CPUs by selecting checkboxes below the graph. The copyright information indicates that this content is from Pass

The article questions the ongoing push for increasing mobile bandwidth, suggesting that the demand for higher data speeds may be stabilizing. Recent data indicates that growth rates for both terrestrial and mobile data are slowing, and that the demand for data speeds is likely to peak below 1 gigabit per second in the near future. Historically, the assumption of continuous growth in broadband rates has driven extensive research and development in telecommunications. However, the actual usage patterns show that most consumer applications do not require speeds exceeding 1 Gb
