The author reflects on their experience managing microservices at Qantas and the challenges of maintaining synchronization and managing codebase complexity. A key strategy they implemented was adopting Polylith alongside Clojure, focusing on simplicity through composition and data, aiming to combat "accidental complexity" in software development. They draw parallels between their past challenges and current struggles faced by LLM coding agents, emphasizing that the choice of programming language significantly impacts managing complexity. The author references Fred Brooks' 1986 essay "No

The content presents a guide for an art project called "microgpt," which is a single 200-line Python script that trains and infers a GPT model without any dependencies. This script encompasses the entire necessary framework, including a dataset of documents, a tokenizer, an autograd engine, a GPT-2-like architecture, the Adam optimizer, and both training and inference loops. The project represents a culmination of various previous projects and aims to distill large language models (LLMs) to their core

The content discusses "xmloxide," a pure Rust reimplementation of the widely-used XML/HTML parsing library libxml2, which became unmaintained in December 2025 due to security issues. Xmloxide aims to be a memory-safe and high-performance alternative that maintains compliance with the same conformance tests as libxml2. Key features and performance metrics include: - Competitive parsing throughput, with improvements of 12% faster on SVG documents. - Faster serialization capabilities (1.5-

The content is a tutorial by Eran Feit on using the "Segment Anything in Python" tool, which allows users to segment any object with a single click using the SAM ViT-H model. The tutorial guides users through setting up the environment, loading the necessary files, clicking to segment an object, and exporting the results with practical code examples. It explains the segmentation pipeline, detailing how a ViT-H image encoder, a prompt encoder, and a mask decoder work together to produce high-quality masks

In his article published on January 9, 2026, Hendrik Erz reflects on a personal tradition of engaging in side projects around Christmas, which has led him to explore various technical topics over the years. Erz details his past projects, including tool development, programming in Rust, analyzing German political agreements, and creating mechanical keyboards. He argues that these endeavors, while seemingly distractions from his work in political sociology, are beneficial for maintaining a well-rounded skill set as a knowledge worker. They help him stay

The author, a computer science instructor at Montana State University and a father of three, emphasizes the ongoing value of computer programming careers, even with the rise of AI tools. He believes that programming is essential for solving problems and managing complexity. However, he raises concerns about junior programmers who might rely on AI to generate code without developing their coding skills. He warns students to write their own code to gain a deep understanding of programming, which is crucial for reading and managing code effectively in an AI-dominated environment

The content critiques the abundance of low-quality material in the realm of optimizing Python for high-frequency trading, noting that many authors blindly adapt C++ techniques to Python without comprehending their underlying principles. A recent example of this issue is cited, where a trading Substack's "optimized" bitset performed significantly worse than a simple boolean array. The author recognized this but still promoted the flawed approach. This pattern of misapplication of C++ strategies to Python is pervasive in low-latency content. Despite these

The article introduces RabbitMQ, an open-source message broker, particularly for those new to message brokers while contrasting it with Kafka. RabbitMQ facilitates asynchronous communication between applications, making it especially useful for microservices architecture. For example, in an e-commerce scenario, instead of a monolithic system processing tasks (like checkout, email notifications, and inventory updates) sequentially and causing delays, breaking the system into microservices can improve efficiency. RabbitMQ acts as a mediator through message queues, allowing services to

The content outlines a process for generating OpenAPI 3.1 documentation from Minitest integration tests using a specific gem. Key points include: 1. **Feedback Acknowledgment**: The team values user feedback and reviews it thoroughly. 2. **Installation and Usage**: - Users should add the gem to their Gemfile and then run installation commands. - Normal Minitest tests are written, with the call to `document_response` for each request to be documented. 3.

Port conflicts in local environments result primarily from conventional practices rather than technical limitations. It is suggested to bind to port 0 and allow the operating system to allocate a port dynamically, which can significantly reduce EADDRINUSE errors associated with default static ports. This approach enables parallel local environments for worktrees and agents without conflicts. Additionally, it is recommended to orchestrate using real addresses instead of configuration files. This principle extends to the management of database names, temporary directories, lockfiles, and socket paths,

The author expresses concern about the security of user data, particularly as more organizations adopt passkeys and use Pseudo-Random Function (PRF) extensions for encryption. While implementing these technologies for features like end-to-end encryption and backups is positive, it poses a significant risk if a user's authentication credential (the passkey) is also used for encryption. Using a real-life example, the author illustrates how a user named Erika might struggle with this setup. After being prompted to use a passkey for

On February 27, 2026, Croatian Interior Minister Davor Božinović announced that Croatia is officially free of landmines, marking a significant milestone 31 years after the end of the Homeland War. The extensive demining effort, which cost around 1.2 billion euros, successfully cleared approximately 107,000 mines and over 407,000 pieces of unexploded ordnance. The process was fraught with danger, resulting in the deaths of 208 individuals, including

Secretary of War Pete Hegseth announced that the Department of War will designate Anthropic as a supply chain risk due to unresolved negotiations concerning exceptions related to mass domestic surveillance and fully autonomous weapons. Anthropic, which has opposed these exceptions, argues that current AI technology is not reliable for use in autonomous weapons and that mass surveillance violates fundamental rights. This designation is unprecedented for an American company and is typically reserved for US adversaries. Anthropic expresses sadness over the situation and emphasizes its commitment to supporting American
