The author shares an experience of encountering a challenging bug while using Microsoft Copilot for coding assistance in Python. The bug arose from an incorrect import statement using the "as" keyword, which allowed them to mistakenly import a Django test class with different semantics than intended. Specifically, they inadvertently imported `TestCase` instead of `TransactionTestCase`, leading to unexpected behavior in database transaction management during tests. The author highlights the consequences of this confusion and the importance of being cautious with naming conventions in imports to avoid

Many good programmers struggle with learning Rust and may even give up due to common mistakes. A key issue is a lack of focused learning; casually experimenting with Rust in short, scattered sessions is often ineffective. As learners encounter more complex concepts, they need to engage deeply to overcome challenges. Initial struggles are expected, but it's important to push through them, as proficiency will improve over time. To succeed, learners should familiarize themselves with Rust's core concepts, such as traits, macros, and smart pointers, preferably

The blog post discusses the complex and largely unexplored area of software sandboxing, highlighting the challenges of gathering comprehensive knowledge and best practices. The author shares personal experiences from working on sandboxing support for Emilua and offers an informal, yet practical, definition of sandboxing as the ability to restrict a process's privileges programmatically, without requiring administrative authority, and through discretionary privilege dropping. The post emphasizes the importance of clarity in understanding this definition and the author's evolving perspective on sandboxing practices, particularly regarding

Jon Sully discusses the upcoming changes to Heroku with the introduction of a new application stack codenamed "Fir." While Heroku has been a reliable platform-as-a-service (PaaS) for a decade, many are curious about the lack of significant updates during that time. The shift to Fir marks a notable change since the previous stack, Cedar, was launched in 2011. As of January 2025, Fir is in early beta for private spaces users, and detailed documentation is

Webtop provides Alpine, Ubuntu, Fedora, and Arch-based containers with full desktop environments accessible through modern web browsers. It uses a Docker manifest for multi-platform support, allowing users to pull the appropriate image for their architecture using the command `lscr.io/linuxserver/webtop:latest` or specific tags. The container has versions with different tags but users are advised to be cautious with unstable versions. For optimal operation, users may need to use Docker with the `--security-opt seccomp=unconf

The announcement introduces voyage-code-3, a new embedding model specifically designed for code retrieval, which outperforms both OpenAI-v3-large and CodeSage-large by averages of 13.80% and 16.81%, respectively, across 32 code retrieval datasets. This model reduces storage and search costs by utilizing lower-dimensional embeddings and quantized formats (int8 and binary) with minimal impact on retrieval quality, thanks to techniques like Matryoshka learning and quantization-aware training.

The author checks their malicious package detector each morning and recently discovered suspicious activity involving a user named "sn4k-s3c" who deployed several packages on NPM targeting the AI coding company Cursor. The packages, with names indicating a connection to Cursor, are designed to collect system data, including sensitive information like AWS keys and GitHub credentials, and send this data to an attacker-controlled server. The deployment likely aims to conduct a dependency confusion attack, hoping that Cursor employees inadvertently install these malicious packages.

The article discusses the complexities of Python's multiprocessing, which requires a deeper understanding of system-level concepts such as process management, race conditions, and locks. Despite its complexity, multiprocessing enables the use of multi-core CPUs for high-performance Python applications. The author plans to guide readers through eight beginner-friendly levels of Python's multiprocessing module, which simplifies process creation and management across different operating systems. The module allows users to focus on implementing multiprocessing without delving into underlying OS mechanisms.

The author reflects on a misconception that all container images must include a complete Linux distribution. They conducted an experiment using a minimal "scratch" base image to create a container that ran a simple Hello World program, which surprisingly worked perfectly. This led them to the realization that using base images like Debian, Ubuntu, or Alpine isn't always necessary. However, the author acknowledges that this initial test was overly simplified, as it involved a statically linked executable that only displayed text. The exploration aims to examine the real

The post discusses creating a customizable, stylable dropdown using only HTML and CSS, addressing the limitations of the default `<select>` element. The approach involves using radio inputs, which serve a similar purpose by allowing the selection of a single value from a list. The example features three options: option-1, option-2, and option-3, with each wrapped in labels for styling. The inputs are placed in a div, and the whole component is enclosed in a fieldset to simulate a select

Sebastian Dörner discusses the importance of organizing code to enhance readability and reduce cognitive load for readers. He emphasizes the significance of making adjacent lines of code coherent by aligning them with the data flow within a method. Two examples of a `getSandwich` function illustrate this concept: one demonstrates a scattered arrangement of code, while the other presents a linear flow that better groups related operations. To further enhance clarity, Dörner suggests using blank lines to visually separate blocks of related code and recommends

The book centers around "nine rules" that guide best practices, structured with a chapter dedicated to each rule. These chapters describe the rules, their significance, and include sub-rules for practical application, enriched with engaging "war stories" that demonstrate the rules in action. While some technical details in the stories may be overwhelming for those unfamiliar with computer technology, they effectively illustrate the principles being discussed. The latter part of the book consolidates the rules into a cohesive narrative, offers reader exercises, tips for
