Writing Great Programming Documentation: A Teaching Guide

2025-03-16

This post uses engaging metaphors and storytelling to illustrate the philosophy of writing high-quality technical documentation. The author argues that the core of documentation is 'teaching', not simply providing information. The post critiques the inadequacy of relying solely on source code, tests, or literate programming tools, emphasizing that documentation should be viewed as a gradual learning process, guiding users from initial contact and quick start to in-depth learning and finally to advanced reference. Each stage should be carefully designed to help users become experts. The author also shares personal teaching experiences and suggests treating documentation writing as a teaching process, focusing on user experience and the gradual acquisition of knowledge.

zlib-rs 0.4.2 Released: A Blazing Fast Compression Library

2025-03-16

zlib-rs 0.4.2 is out, boasting significant performance improvements! It's now (to our knowledge) the fastest API-compatible zlib implementation for decompression, and outperforms the competition in key compression scenarios. This release leverages clever multiversioning and DFA optimizations to efficiently select the optimal implementation at runtime, leading to dramatic speed gains. Benchmarks show zlib-rs significantly outpacing zlib-ng and zlib-chromium in decompression. While further compression performance improvements are planned, zlib-rs is already exceptionally fast and is seeking funding to complete the remaining work.

Optimizing Integer Division in C++: Templates, Lambdas, and Metaprogramming

2025-03-16

This article explores several approaches to optimizing integer division in C++. Direct integer division can be inefficient, especially when the divisor is known at compile time. It starts by demonstrating the use of C++ template functions, allowing the compiler to optimize when the divisor is a compile-time constant. However, template functions can increase code complexity. The article then attempts to simplify the code using lambda expressions and template lambda expressions, but encounters issues with directly using template lambdas, requiring the use of `operator()` for invocation. Finally, it compares the pros and cons of various methods, including simple lambdas and more advanced template metaprogramming techniques, suggesting the most suitable approach depending on the context.

Local-First & Ejectable Apps: The Future of Data Ownership

2025-03-16

Cloud apps offer convenience, but traditional desktop software provides better data ownership. 'Ejectable' apps bridge this gap, letting users self-host the backend sync server. This means saving a workspace and downloading a server executable, allowing seamless switching between cloud and local versions. Data remains accessible even if the cloud service shuts down, ensuring longevity like classic apps like DOOM.EXE. The author highlights Thymer as an example of this approach.

Codon Compiler: A Glimpse of Faster Python?

2025-03-16

Codon is a compiler aiming to dramatically improve Python's execution speed. While the author previously encountered compilation issues, recent updates have resolved them. Although a test script didn't show speed improvements, Codon demonstrated significant performance gains in NPBench NumPy benchmarks, reaching up to 900x speedup, largely due to the Codon team's direct port of NumPy. While the author didn't replicate the benchmark results, a trial of a supposedly 300x faster Python script hints at Codon's potential in specific use cases.

Recreating Photoshop: A Developer's Summer Project from 2006

2025-03-16

In the summer of 2006, a developer, aiming to improve his manga reading experience, created a manga reader named Fiew using C++ and the Windows API. Driven by ambition, he then tackled the formidable task of recreating core Photoshop functionality, resulting in the image editor, Fedit. Fedit adhered to principles of zero installation and a single executable file, and meticulously replicated Photoshop's interface and features, including floating tool windows, a color picker, and layer management. Months of development, overcoming numerous technical hurdles, culminated in a successful thesis, a software engineering job, and the open-sourcing of Fedit's code and documentation.

Debugging a Full-Viewport HTML Dialog Modal

2025-03-16

The author encountered a height issue while using the HTML `` element to create a side panel: a gap appeared at the bottom, preventing it from taking up the full screen height. The debugging process involved various methods, including consulting AI tools like Claude and ChatGPT. The culprit was a default Chrome style applied to the `` element: `max-height: calc(100% - 2em - 6px);`. Adding `max-height: inherit` or `max-height: 100vh` resolved the problem. Further investigation into the HTML specification revealed this default style was added to fix a previous bug, highlighting the ever-evolving nature of web standards.

40-Year-Old Conjecture on Hash Tables Shattered

2025-03-16

For four decades, computer scientists have accepted Andrew Yao's 1985 conjecture on the efficiency of hash table lookups. However, Krapivin and his team have developed a novel hash table that dramatically outperforms Yao's worst-case bound. Their new algorithm achieves a far faster query and insertion time, and surprisingly, the average query time is a constant, irrespective of the table's fullness. This groundbreaking result not only refutes a long-held belief but also opens new avenues for hash table optimization.

The AI Job Market Shift: Is 2025 a Career Winter?

2025-03-16

The rapid advancement of AI, especially large language models, has created a challenging job market for many software engineers, particularly those who entered senior roles between 2010 and 2020. Traditional management skills are less valued now, replaced by a demand for meticulous detail-orientation, rapid project execution, and adaptation to the AI transition. This leaves many senior leaders feeling overwhelmed, while potential leaders skilled in technical details and rapid iteration struggle for promotion. Simultaneously, rapid AI advancements challenge established company advantages, demanding product and development process redesign. This creates immense pressure on job seekers, with reduced hiring, promotions, and slower salary growth. In short, the current job market is highly competitive, demanding more from job seekers.

Researchers at GitHub Security Lab discovered two critical authentication bypass vulnerabilities (CVE-2025-25291 and CVE-2025-25292) in the ruby-saml library. Attackers can use a single valid signature to forge SAML assertions, allowing account takeover by logging in as any user. The vulnerability stems from ruby-saml's use of two different XML parsers (REXML and Nokogiri), creating a parser differential exploited by attackers. Version 1.18.0 fixes the vulnerability; all users are urged to update immediately.

An Eight-Year-Old Polyomino Tiling Algorithm: Backtracking Search with Heuristics

2025-03-15

This article details an algorithm for solving the polyomino tiling problem. The core idea is to transform the geometric problem into a graph theory problem and use a backtracking search algorithm with various heuristics. First, the algorithm preprocesses to calculate all possible placements, constructing a bipartite graph representing all possibilities. Then, a backtracking search algorithm finds a subset of placements satisfying the conditions, optimized by heuristics such as prioritizing constrained grid points and splitting the grid. The algorithm demonstrates good generality and robustness in handling arbitrary grid shapes and polyomino sets. The author also discusses limitations and future improvements, such as transforming the problem into a SAT problem for solution.
