Rethinking Literate Programming: Is Knuth's Approach Obsolete?

2025-01-13

This article offers a critical examination of Donald Knuth's literate programming approach. The author argues that Knuth's method overemphasizes typesetting while neglecting the crucial aspect of code organization, resulting in static, less interactive documentation. The author advocates for a literate programming style that prioritizes code organization and interactive feedback, illustrating its advantages with a simple interpreter he created. The key takeaway is that effective literate programming should allow developers to modify and run code directly within their programming environment, not just passively read a static document.

London Underground Live Map Shut Down After 15 Years

2025-01-13

A developer built and maintained a website displaying real-time London Underground and bus routes using TfL's open data since 2010. The site, featured in BBC and Guardian, gained popularity. However, on January 7th, 2025, the developer received a cease and desist from TfL regarding the Tube map schematic. Despite willingness to modify, the developer shut down the site, citing TfL's heavy-handed approach. This story highlights the conflict between large organizations and individual developers, and the complexities of open data applications.

Chumby 8 Kernel Upgrade: Solving the 100% CPU Usage Mystery

2025-01-13

While upgrading the Linux kernel of his Chumby 8 device to version 6.x, the author encountered a persistent 100% CPU usage problem. Through time-reversal debugging, kernel profiling, and a deep dive into the `/proc/stat` file, the root cause was traced to a timing issue in the kernel code that reads the PXA168 hardware timer register, resulting in inaccurate idle time counting. The author fixed this problem and contributed the solution back to the main Linux kernel.

/etc/glob: The Untold Story of Early Unix Shell Globbing

2025-01-13

This article delves into the history and function of `/etc/glob` in early Unix systems. Before the V7 Bourne Shell, Unix shell globbing wasn't handled by the shell itself but delegated to the external program `/etc/glob`. `/etc/glob` received the command and arguments, expanded wildcards, and then executed the command. The article details how `/etc/glob` worked across different Unix versions, including handling escaped characters and the rationale behind using an external program—likely due to resource constraints in early systems.

The Paradox of Elegant Programming Languages: Why Simplicity Can Be a Curse

2025-01-13

Some programming languages fail to gain traction due to obscurity or overly ambitious designs. The article explores the challenges faced by concise, elegantly designed languages like BF and Scheme, where developers often prioritize building their own implementations rather than using existing ones. The author argues that a balance between simplicity and practicality is crucial. Multiple implementations are beneficial only when a strong user community exists and demands diverse implementations. The success of Clojure and Racket suggests that languages need to reach a critical mass to attract users who focus on application development, rather than implementation.

Comptime Configuration in Zig: Clever Design in httpz and ztl Libraries

2025-01-13

This article explores the techniques of using compile-time metaprogramming for configuration in the Zig programming language. The author uses their httpz and ztl libraries as examples, demonstrating how a generic type parameter `T` can simultaneously serve as both application context and configuration. Functions defined within the `T` type can override the library's default behavior, while fields in `T` can configure scalar values. Compile-time checks ensure the correctness of the configuration and allow for compile-time optimizations, such as adjusting the virtual machine stack size based on the configuration. While this approach requires users to provide configuration at compile time, it offers significant performance improvements and is an effective strategy for building flexible and efficient libraries.

Qubes OS Templates: Secure, Efficient VM Management

2025-01-13

Qubes OS utilizes a template system for managing virtual machines, enhancing security, storage efficiency, and boot speed. Each template shares its root filesystem, with applications running and storing data within qubes. Updating a template automatically updates all qubes based on it after a restart. Software should be installed in templates, not app qubes. Qubes offers templates based on Fedora, Debian, and more, plus community templates. Users can install, update, uninstall, or switch templates via command-line or GUI tools. Uninstall warnings are normal. Switching templates requires updating all qubes based on the old template. Template security is crucial; install software only from trusted sources.

Invariants: A Powerful Tool for Writing Correct Code

2025-01-12

This article explores the concept of 'invariants' in programming and their applications. Starting with a small example—writing a binary search variation that computes the insertion point—the author demonstrates how defining and maintaining invariants leads to correct code. Invariants, the article explains, are properties that hold true throughout a system's dynamic evolution, simplifying reasoning by avoiding the complexities of considering numerous execution paths. Examples from projects like Cargo, rust-analyzer, and TigerBeetle illustrate the benefits of using invariants in large systems, such as improved maintainability and performance. The author concludes by summarizing the importance of invariants in both small-scale and large-scale programming, highlighting their value in writing correct and efficient code.
