The article by Ayush Newatia discusses implementing persistent connections in Rack, focusing on server-sent events (SSEs). Unlike WebSockets, which are bi-directional, SSEs allow a client to maintain an open connection where only the server can send messages. The article explains using the JavaScript EventSource API to create an HTML page that listens for server messages. It details building a server endpoint to send events, emphasizing the proper content-type header and reformatting the output for the client.

The content presents a scenario where a user automates a repetitive task by creating a Python script, leading to the evolution of the script into a library as they add more functionality. Initially, everything works well, and they enjoy their newfound free time. However, as they share the library with others, users struggle to replicate the environment, facing various issues, including obscure bugs and dependency conflicts. The situation worsens when the user installs new packages, causing their environment to break, leading to frustrations and ultimately a

Underjord is a small team that specializes in Elixir consulting and contract work. Recently, a team member worked on implementing Voice Activity Detection (VAD) in Elixir using the Silero VAD model via ONNX, creating a proof of concept that should be compatible with most Elixir setups. They noted the ease of using Membrane for media processing, which now helps in managing dependencies. The author relied on a post by Sean Moriarty for guidance on integrating Silero VAD with Elixir

There has been ongoing discussion about the possibility of a capacitor being installed backwards in Apple's Macintosh LC III, a model produced from 1993 to 1994, primarily for the education market. Skepticism exists in the community since Apple did not recall the LC III. The author shares their personal experience after purchasing a Performa 450, noting that the capacitors (C19, C21, and C22) were installed with the negative sides facing upward, aligning with the PCB indications.

Ben Houston shares his experience transitioning from Kubernetes to Google Cloud Run for container orchestration. He initially adopted Kubernetes while developing an online 3D editing platform, Clara.io, and later Threekit.com. Although Kubernetes seemed suitable for managing services at scale when it emerged in 2018, Houston encountered significant challenges over time, including: - **High Costs**: Kubernetes required substantial infrastructure investment, with hidden costs beyond just DevOps efforts. The need for a bare-bones cluster with redundancy led to

Two men, Alexander Moucka and John Erin Binns, have been arrested for allegedly stealing data and extorting companies using the cloud storage service Snowflake. They are implicated in hacking incidents affecting major corporations, including AT&T, where hackers accessed the personal information of about 110 million customers. A third suspect, a hacker known as Kiberphant0m, remains at large, actively extorting victims. Investigations suggest Kiberphant0m may be a U.S. Army soldier formerly stationed

The author explores the future of mainstream programming languages, focusing on Java and Go. They argue that Java, often underrated, is both easy to learn and has a strong type system that helps prevent incorrect states. While Java's verbosity contributes to its simplicity, the misuse of its features can lead to complex code. The author believes that the ideology surrounding Java often causes it to be overlooked, highlighting frameworks like Spring Boot and alternatives like Javalin. In contrast, Go is praised for its simplicity and user-f

The paper discusses the implementation of the GNU make "jobserver," aimed at those interested in understanding how GNU make handles job parallelism and how it manages to wait for different types of events simultaneously, such as signals and file descriptors. GNU make is known for efficiently rebuilding programs from source and has a unique ability to run commands, or "jobs," in parallel. There are three types of parallelism in GNU make: no parallelism (jobs run serially), infinite parallelism (as many jobs as

The content discusses a Wii homebrew project that enables the execution of JVM bytecode on the Wii's Starlet processor using Palapeli's exploit. The approach involves running ARM code to switch the Starlet into Jazelle mode, after which it can jump to the specified JVM bytecode. The example provided indicates that the system prints the state of the stack and the first eight local variables after execution. However, it also notes that many JVM instructions are not natively supported by Jazelle and must be

The article discusses Malors Espinosa, a graduate student at the University of Toronto, who aimed to create a thought-provoking math problem suitable for high school students. He drew inspiration from a textbook on chaos and the Menger sponge, a fractal shape constructed by recursively removing cubes from a larger cube. Through his initiative, he sought to engage students in mathematical research and proof-writing by providing them with a challenging yet solvable question. The Menger sponge serves as a prime example of fractals'

The article discusses the development of a system called HumanLayer, designed to enable teams to deploy AI agents with built-in human oversight, reducing the risks associated with AI decision-making in production environments. Initially focused on automating tasks for data teams—like removing unused tables—the team faced challenges with AI reliability and concerns about giving AI agents direct access to production systems. The solution involved creating approval flows where the AI would request human permission before taking actions, like sending Slack messages, ensuring that stakeholders endorsed each step.
