The author shares updates on their progress in developing jank, a Lisp dialect with seamless C++ interoperability, funded by individual GitHub sponsors and Clojurists Together. Clojure already has a seamless interop experience with Java, which the author aims to replicate for C++ in jank, claiming it as a pioneering effort for a Lisp language. They point out the challenges of achieving this from a dynamically typed and JIT-compiled language, emphasizing that jank is venturing into uncharted territory

In a blog post dated May 6, 2025, namvdo discusses the concept of memory safety in programming languages, contrasting it with static typing. Memory safety ensures that operations are restricted to allocated memory regions, preventing errors such as accessing invalid memory locations. Using Java as an example, the author illustrates memory safety by describing how it handles integer arrays and exceptions that arise when trying to access indices beyond the allocated size. The post also mentions Java's garbage collection, which automatically manages memory allocation and

The content discusses a tool for converting a Docker image into an executable file that can be easily shared. Users are encouraged to check the documentation for available qualifiers. To use the tool, one needs to download a binary and ensure that Docker, GoLang, and gzip are installed. The process involves creating a new binary that embeds the Docker image as a tarball. When the executable runs, it checks for the required Docker image on the user's system and, if absent, attempts to extract it from the embedded

The author reflects on their experience with Kubernetes, which began in 2018 when they were intrigued by its potential. They set up a small cluster at home using a NUC (Next Unit of Computing) device. The main takeaway from their experimentation was that while Kubernetes automates many tasks (like maintaining the desired state of Pods and managing TLS certificates with cert-manager), it can be resource-intensive and may not be practical for smaller setups. The author noted that Kubernetes consumes considerable CPU and memory, making their

The content discusses a project that enables users to have natural spoken conversations with a Large Language Model (LLM) using their voice, featuring real-time responses. The project is currently in an early preview phase and operates through a sophisticated client-server system designed for low-latency interaction. To set up the environment, users can clone the repository and choose to bundle the application using Docker, which simplifies the process by handling dependencies and necessary installations. Key steps include building Docker images, starting services, and pulling the

The author discusses their recent experiences at the Recurse Center, where they explored GPU-friendly algorithms, specifically focusing on bitonic sort. This post introduces bitonic sort as a type of parallel sorting algorithm characterized by its ability to handle sorted sequences, including its unique formation from two monotonic sequences. The post explains that bitonic sort operates in O(log²(n)) parallel depth, which contrasts with the O(n*log(n)) time complexity of traditional sequential sorting algorithms. The key to its efficiency lies in

In March 1951, CIA analyst Sherman Kent experienced confusion following the release of his team's report on the potential for a Soviet invasion of Yugoslavia, which labeled the threat as a "serious possibility." A conversation with the chairman of the Policy Planning Staff revealed a stark misunderstanding of this phrase; Kent believed there was a 65% chance of an attack, while others interpreted the likelihood as much lower or higher, reflecting significant discrepancies in judgment among colleagues. This incident highlighted deeper issues in how intelligence

In a recent Discord discussion, the idea emerged that a good senior developer should be proficient in any programming language. Reflecting on nearly 18 years in the tech industry and experience with various languages, the author questions whether language flexibility is a key trait of senior engineers or if deep specialization is more beneficial. They reference advice from "The Pragmatic Programmer," which suggests learning a new language each year to broaden one's approach to problem-solving, although the author believes this shouldn't lead to overwhelming pressure. Exposure to different

In the post by Vítor Fróis, the concept of Linear Regression is explained through a practical example of determining house prices based on size. It illustrates how learning, in a computational sense, involves refining initial guesses through data analysis. By plotting house prices against size, a clear upward trend emerges, showing that larger homes generally command higher prices. When a homeowner seeks to price their house, they can draw a line on this scatterplot that approximates the trend in previous sales, using the linear

The article discusses the concept of graceful shutdown in applications, emphasizing its importance for HTTP servers and containerized applications. It begins by explaining the necessity of catching termination signals, which are software interrupts in Unix-like systems that prompt a process to take action upon receiving a notification from the operating system. Specifically, the article highlights three key termination signals: SIGTERM, SIGINT, and SIGHUP, with SIGTERM and SIGINT being the most relevant for initiating graceful shutdowns. It notes that the Go
