Vanity SHA-1 Generator: A Clever Case-Changing Approach

2025-03-31

This code attempts to generate a SHA-1 hash matching the target prefix "20250327" by manipulating the capitalization of words in an input text. It parses the text, identifies mutable words, and then iterates through all possible case combinations, calculating the hash and comparing it to the target. If a match is found, the modified text is written to a file. The program demonstrates a clever brute-force approach, using case variations to try and generate a specific hash prefix, showcasing an understanding of hash algorithms and combinatorics.

Automating Transaction Tracking in Interactive Fiction with LLMs

2025-03-31

An author automated transaction tracking logic in an Emacs-based interactive children's book using an LLM (via gptel). The book features a protagonist who earns, saves, and spends money. Each passage initially contained code tracking transaction amounts. To enhance educational value, the author wanted to show how the cash balance was calculated. Using gptel, a simple prompt allowed the LLM to automatically add a JSON object (cashOperations) to each passage's code, tracking changes in cash with operation type, amount, and description. This significantly improved efficiency, paving the way for adding an arithmetic explainer feature.

C/C++: Performance Over Correctness?

2025-03-31

This article delves into the pitfalls of "undefined behavior" in C and C++. In the pursuit of ultimate performance, compilers often take a laissez-faire approach to uninitialized variables, arithmetic overflow, infinite loops, and null pointers, rather than reporting errors or inserting safety checks. This makes programs difficult to debug and maintain, potentially leading to unpredictable crashes. The author uses several examples to illustrate how C/C++ compilers prioritize optimization, even at the cost of program correctness and predictability, prompting reflection on this design philosophy.

Linux Desktop: Great; Linux Server: A Mess? FreeBSD's Elegant Response

2025-03-31

The author contrasts the desktop and server experiences of Linux, finding the desktop remarkably user-friendly. However, the server side suffers from excessive complexity due to systemd and abstraction layers like Docker and Kubernetes, making troubleshooting difficult. FreeBSD, conversely, shines with its simplicity, stability, and ease of maintenance, even in disaster recovery scenarios. However, a growing trend of open-source software relying heavily on Docker deployment, lacking native installation methods, poses a challenge for FreeBSD users. The author highlights deployment difficulties with Immich and BunkerWeb as examples.

Turso Offline Sync Public Beta: Always-On Apps, Even Offline

2025-03-31

Turso is thrilled to announce the public beta of Turso Offline Sync! Your applications can now function seamlessly, even without internet connectivity. Local database operations continue normally, automatically syncing upon reconnection. Leveraging embedded replicas, your local database (on-device or server) stays in sync with your Turso Cloud database, with changes propagated to all replicas. This beta addresses previous limitations of unidirectional sync, enabling fast local writes, offline capabilities, and later syncing to the Turso Cloud. This simplifies development for local-first apps, mobile apps, POS systems, field data collection, and IoT applications. The beta currently supports TypeScript and Rust, and includes features like bi-directional sync, remote write support, WAL sync checkpointing, and conflict detection (resolution coming soon).

Transatlantic 1-2-3 Debugging: A Zeroth Law Story

2025-03-31

Around 1990, the author debugged a client's Lotus 1-2-3 setup via fax due to expensive transatlantic phone calls. By guiding the client through commands like `/ppomr` and `/ppoml` to obtain printer margin information, the issue was resolved. This highlights the 'Zeroth Law of Debugging': use the smallest, fastest test case for rapid iteration and efficient problem-solving.

Windows 11's Blue Screen of Death Gets a Makeover

2025-03-31

Microsoft is revamping the Blue Screen of Death (BSOD) in Windows 11. The new design ditches the classic blue screen, sad face, and QR code for a simpler, black screen reminiscent of Windows update screens. Currently appearing as green in test builds, the final color remains unclear. Microsoft aims for faster user recovery while retaining technical details. This is the first major redesign since the sad face addition in Windows 8. The new BSOD simply states, "Your device ran into a problem and needs to restart."

curl's Experimental HTTPS RR Support: The Next Generation of DNS Records

2025-03-31

curl now experimentally supports the new DNS record type HTTPS RR, offering a more modern way than SRV and URI to convey service metadata such as ECH configuration, ALPN lists, target hostnames, ports, and IP addresses. HTTPS RR enhances HTTPS connection security (via ECH encryption of the SNI field) and efficiency (by pre-fetching HTTP/3 support information), and simplifies service discovery. curl achieves HTTPS RR resolution through DoH, getaddrinfo(), or c-ares, but currently lacks runtime disabling and still has incomplete HTTPS RR support.

Taming the C++ UB Dragon: A Status Update on Safety and Security Improvements

2025-03-31

C++'s undefined behavior (UB) has long been a source of security vulnerabilities and hard-to-debug errors. The C++ standards committee is actively working to address this, making progress in C++26 by eliminating UB for uninitialized variables and enhancing the standard library's bounds safety. Future efforts will systematically catalog and address remaining UB cases using erroneous behavior, language profiles, and contracts. The goal is to achieve parity with other modern memory-safe languages in terms of security vulnerabilities, without sacrificing C++'s performance or flexibility.

The Perils of Native Resource Management in .NET: A Tale of Unexpected GC Behavior

2025-03-31

This post delves into the potential pitfalls of native resource management in .NET. The author uses a RocksDB example to illustrate how unexpected garbage collection behavior can lead to native resources being released before use, resulting in crashes. The root cause lies in the fact that local variables and instances can be garbage collected during a method call. The article ultimately advocates for using SafeHandle to manage native resources safely, preventing these hard-to-reproduce Heisenbugs.

Linus Torvalds Rages Against 'Turds' in Linux 6.15 Kernel

2025-03-31

Linus Torvalds, the creator of Linux, expressed his strong displeasure with the newly merged hdrtest code in the Linux 6.15 kernel, specifically within the Intel Xe driver. This testing code generates unnecessary temporary files during the build process, cluttering the source tree, slowing down the build, and even affecting filename completion. Torvalds referred to it as "turds" and demanded its removal, suggesting that developers run it as a separate test instead of integrating it into the regular build. While the code aims to ensure the integrity and kernel-doc test-passing of DRM header files, its crude implementation infuriated Torvalds.

AI: The Coming Fragmentation of Software Engineering

2025-03-30

The author's wife uses Lovable, an AI tool, to build a social platform. While efficient, the AI frequently gets stuck, requiring human intervention. This observation leads the author to predict a future where software engineering is fragmented: a large pool of low-skilled 'AI prompters' supported by a smaller number of highly skilled specialists who resolve issues and optimize performance. AGI, the author argues, is overhyped; the reality is an AI-assisted development model where AI handles routine tasks, but complex problem-solving and architecture remain crucial human roles. This shift will result in fewer software engineering jobs, but survivors will ascend to higher-level positions requiring stronger architectural design skills and leadership. The future is bright for the adaptable, bleak for the complacent.

Why My Personal Website Is Built With C

The author, blogging since 2017, tried Django and Nuxt.js for their website, but abandoned them due to high maintenance costs. They finally chose C and the md4c library to build a static site, prioritizing speed, minimal dependencies, and long-term stability. This significantly reduced maintenance overhead. In contrast, the author found other static site generators like Hugo to be overly powerful and unnecessarily complex for their needs.
