Property-Based Testing: Why it Trumps Unit Testing for Complex Inputs

2025-05-21

This article debates the merits of property-based testing (PBT) versus traditional unit testing. The author argues that while unit tests suffice for functions with single inputs, the combinatorial explosion of edge cases in multi-input functions makes PBT, with its randomized input generation, superior at uncovering hidden boundary errors. However, PBT has a learning curve; mastering complex input generation strategies is crucial. Most PBT examples are too simplistic to showcase its true power in handling complex input spaces.

Rust's `panic` and `unwrap()`: When and How to Use Them?

2025-05-21

This article delves into the usage of `panic` and `unwrap()` in the Rust programming language. The author argues that `panic` shouldn't be used for general error handling, but as a signal of bugs within the program. `unwrap()` is acceptable in tests, example code, and prototyping, but should be used cautiously in production as it can lead to program crashes. The author thoroughly explains runtime invariants and why it's sometimes not possible or desirable to move all invariants to compile-time invariants. Finally, the author recommends using `expect()` over `unwrap()` when possible and discusses whether linting against `unwrap()` is a good idea.

The Vanishing Junior Engineer: A Crisis in Computer Science Education?

2025-05-21

The rise of AI coding assistants is causing a decline in junior engineering roles. This isn't a temporary blip, argues the author, but a fundamental challenge to computer science education. Traditionally, junior engineers handled coding, while seniors focused on problem decomposition and architecture. Now, AI can do much of the coding, diminishing the junior role's value. The author proposes a return to the mathematical roots of computer science, emphasizing abstract problem-solving skills. Rigorous, in-person exams are suggested as a way to test these crucial skills, rather than just coding proficiency, preparing students for success in the age of AI.

Hacking the Exception Handler: A Tale of DirectX, Flash, and Code Modification

2025-05-21

A team encountered a frustrating issue while using `SetUnhandledExceptionFilter` for unhandled exception handling: Direct3D and Flash were installing their own exception filters, rendering the team's solution ineffective. To resolve this, they employed a bold strategy: directly disabling the `SetUnhandledExceptionFilter` function via code modification to ensure their exception handler took precedence. The article details the process of code modification, including obtaining the function address, verifying the initial instructions, and utilizing `VirtualProtect` and `FlushInstructionCache` APIs for code replacement. Their solution restored proper exception reporting functionality.

The Elegant Connection Between Polynomial Multiplication, Convolution, and Signal Processing

2025-05-21

This post explores the connection between polynomial multiplication, convolution, and signal processing. It begins by visually explaining polynomial multiplication using tables and diagrams, revealing its fundamental nature as a convolution operation. The post then introduces discrete signals and systems, focusing on linear time-invariant (LTI) systems. It explains that any signal can be decomposed into a sequence of scaled and shifted impulse signals, and the response of an LTI system can be calculated using convolution. Finally, it briefly touches upon the properties of convolution and its relationship to the Fourier transform, highlighting that the Fourier transform of a convolution equals the product of the Fourier transforms of its operands, enabling efficient convolution computation.

Clojure Web Development: A Philosophical Look at Frameworks vs. Libraries

2025-05-21

This article delves into the framework vs. library choice in Clojure web development. The author argues that popular web frameworks, like industrial automation, solidify architecture and thought processes, while the Clojure community favors flexible library combinations. Using Ring and Jetty as examples, the article explains the fundamental principles of building Clojure web applications, including request handling, middleware, and routing mechanisms. It also recommends various introductory resources and mature web stacks, helping developers find their suitable path within the Clojure ecosystem.

Rust's New Approach to Uninitialized Buffers: The Buffer Trait

2025-05-21

Uninitialized buffers in Rust have been a long-standing challenge. John Nunley and Alex Saveau introduced a novel solution using a `Buffer` trait. This trait enables safe reading into uninitialized buffers, providing implementations for `&mut [T]` and `&mut [MaybeUninit]`. It also cleverly leverages the spare capacity of `Vec` and encapsulates the unsafe `Vec::set_len` call. This approach is now integrated into rustix 1.0 and released as a standalone library, `buffer-trait`, with potential future inclusion in Rust's standard library.

Is Your Code Worthless? A Rewriting Experiment Reveals the Truth

2025-05-21

The author argues that the value of code in software development is overestimated, using a personal anecdote. A web portal that took a team six months to build was rewritten by the author alone in just two weeks. This wasn't due to superior coding skills, but because the true value lies in teamwork, business logic, and design, not the code itself. The code can be discarded and rebuilt, while team experience and design principles are the core assets. The article prompts deep reflection on software development costs and value, encouraging readers to conduct similar experiments.

Software Engineering: An Art of Discovery, Not Just Engineering

2025-05-20

Software engineering is not merely an engineering practice; it's more of an art, full of the joy of discovery. The article uses early computer animations as an example to illustrate how a deep understanding of underlying technologies can lead to unexpected creativity. It argues that in software development, the interplay between vision and engineering is bidirectional and nonlinear, rather than linear. The author critiques the drawbacks of over-reliance on abstraction layers and black-box thinking, arguing that this limits creativity and innovation. The same applies to software organizations: over-emphasizing team autonomy while neglecting inter-team collaboration leads to low overall efficiency. The author calls for a return to understanding underlying technologies to spark true innovation.

Revolutionizing Embedded Audio DSP Development

2025-05-20

Embedded audio DSP development has long suffered from lengthy iteration cycles, complex cross-platform porting, and a lack of real-time configurability and visibility. Traditional workflows require engineers to repeatedly code, compile, and test to fine-tune audio parameters, a process that is time-consuming and hinders A/B comparisons. Furthermore, cross-platform porting is challenging because audio algorithms are often optimized for specific processor architectures, making direct migration to new platforms difficult. This article introduces a new development platform that significantly reduces development time and enables cross-platform reuse by providing graphical audio tools, modular design, and real-time tools—achieving up to a 10x speedup. The platform hides low-level details like word length, byte order, and cache quirks, allowing the same audio graph to run on different architectures (ARM, Xtensa, RISC-V) without code changes.

Starina: A Microkernel OS with a Hypervisor-as-a-Library Approach

2025-05-20

This post introduces an innovative approach to Linux compatibility in the Starina operating system: integrating the virtual machine monitor (VMM) as a library within applications. Unlike traditional standalone VMMs, Starina's `starina_linux::Command` API lets developers run Linux programs similarly to `std::process::Command`, interacting with the VM via a virtual file system (virtio_fs). This design simplifies development and has the potential to achieve faster startup times than native Linux. Currently, basic file I/O is supported; future work includes adding networking, persistent storage, and enhanced containerization.

Deputy is an experimental dependently-typed programming language embedded in Clojure, featuring inductive datatypes. It explores the implications of a Lisp-based REPL-driven workflow for both programming and type checking. Implemented as a Clojure library, it allows programmers to leverage the host language while working at the type level. This enables type-level computations that depend on values, unlocking powerful programming patterns. Importantly, despite the rich dynamic semantics of types, type checking remains a purely compile-time operation.
