Bots and spam pose significant challenges for online platforms, and while traditional CAPTCHAs help combat these issues, they often require proprietary software enhancements and may compromise user privacy. To address this, the authors introduce "MapTCHA," a CAPTCHA system that utilizes the uncertainties in computer vision imagery interpretation to verify human involvement in mapping efforts. Users identify images of correctly recognized objects, such as building outlines, from various cases: known positives (objects found in both AI predictions and OpenStreetMap), unknown cases (objects

The Interop Project is a collaborative initiative among browser vendors and platform implementors aimed at enhancing the interoperability of the web platform for users and developers. Each year, the project identifies key focus areas for improvement, encouraging browser engines to prioritize common features for quicker usability. Progress is tracked through an Interop dashboard that measures the pass rate of web-platform tests in these areas. In 2024, the Interop score has significantly improved, reaching 95% in major browsers, up from 46% at

The article discusses adding graphical support to a Chip-8 emulator, building on previously established instruction implementation capabilities. Initially, the emulator executed instructions sequentially, but now the focus is on incorporating control flow, allowing conditional execution and loops. Two essential control flow instructions are highlighted: the jump instruction (0x1NNN), which alters the program counter (PC) to redirect execution to a specified address (NNN), and a conditional skip instruction that checks if a register (X) equals a value (

In August 1963, W.A. Blankinship published a paper on a fast algorithm for computing the Greatest Common Divisor (GCD) for multiple numbers, titled "A New Version of the Euclidean Algorithm." This article aims to code Blankinship's algorithm in C and explores its application in solving Diophantine equations. The discussion will be structured into four parts: an introduction to Diophantine equations, an overview of the GCD, the relationship between the GCD

In Anno 1800, the sun's position is tied to the camera, causing shadows to consistently fall in one direction as the camera rotates. This creates a time-lapse effect, differing from the fixed sun position option, which mimics real-world lighting but can lead to unflattering camera angles where shadows fall behind objects, resulting in a flat appearance. The author appreciates the flexibility of the camera-relative sun for its significant visual impact, noting how shadows influence the game's aesthetic. They also commend

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
