Programmer Calls Out OAuth Providers for API Flaws

A programmer publicly criticized several OAuth providers (GitHub, Facebook, TikTok, Strava, Naver, and others) for various API inconsistencies. Issues included incorrect status codes, non-standard error responses, inconsistent parameter naming, and flawed token expiration formats. The author urged these providers to rectify these problems, expressing particular confusion over Naver's design choices. The post also highlighted the lack of support for HTTP Basic authentication, later clarifying that while optional in OAuth 2.1, most providers' lack of PKCE support renders them non-compliant with either specification.

High-Resolution Bitmap Graphics with Commodore 64 BASIC 2.0: A Fast Screen Clearing Routine

This article demonstrates efficient high-resolution bitmap graphics handling in Commodore 64 BASIC 2.0, focusing on a fast screen clearing routine. The author points out that native BASIC lacks direct bitmap manipulation commands, making conventional clearing slow. A clever solution utilizes the BASIC string storage mechanism: long strings filled with CHR$(0) overwrite the bitmap memory, achieving fast clearing. The technique is illustrated with a cosine function plotting example.

Python Dependency Management: A Raging Inferno

2024-12-15

This article delves into the complexities of Python dependency management, likening it to building a bonfire in a dry forest. The author argues that Python dependencies aren't simply a matter of `pip install`; they encompass project packages, system packages, the operating system, hardware, and the environment itself. Good dependency management is crucial for reproducibility—ensuring consistent results across different environments. The article details version control, environment isolation, definition files, lock files, and other key concepts. It then provides a comprehensive comparison of numerous tools, including pip, venv, virtualenv, pip-tools, Pipenv, Poetry, PDM, pyenv, pipx, uv, Conda, Mamba, conda-lock, and Pixi, analyzing their strengths, weaknesses, and use cases. Finally, the author offers tool recommendations based on different scenarios (administrative privileges, dependency types, operating systems, etc.) and looks ahead to future trends in Python dependency management.

This article explores the phenomenon of prime numbers plotted on polar coordinates exhibiting spiral or linear patterns. The author uses Python code, employing SymPy to generate prime numbers and Matplotlib for visualization. Results show that as the number of primes increases, the pattern transitions from spirals to straight lines. This isn't unique to primes; it's related to rational approximations of $2pi$. The article explains the underlying mathematics and explores the connection between prime distribution and pattern sparsity.

A Java JIT Compiler and Runtime in Common Lisp: OpenLDK

OpenLDK is a Just-In-Time (JIT) compiler and runtime environment for Java, implemented entirely in Common Lisp. It bridges the gap between Java and Common Lisp by incrementally translating Java bytecode into Lisp, then compiling it into native machine code. This unique approach allows seamless mapping of Java classes to Common Lisp Object System (CLOS) classes, enabling effortless integration between Java and Common Lisp codebases. While not designed for high performance, OpenLDK offers a practical solution for integrating Java libraries into a Lisp workflow. Currently, it primarily supports Linux and SBCL, and is a work in progress with many features yet to be implemented, such as support for class files beyond Java 8 and bytecode verification.
