Liskov Substitution Principle: The Real Meaning of Inheritance

2025-01-22

This article delves into the Liskov Substitution Principle (LSP), a frequently misunderstood SOLID principle. Using the classic rectangle-square problem, it illustrates common LSP violations: subtypes failing to fully substitute base types. The author advocates using composition and interfaces over inheritance to avoid LSP violations, providing a practical example with payment processing. Common LSP violations, such as throwing unexpected exceptions and returning inconsistent results with the base type, are outlined, along with how to ensure LSP compliance through contract testing and clear pre/postconditions. Ultimately, the article emphasizes that LSP is about more than just inheritance—it's about behavioral compatibility and meeting expectations. Following LSP leads to more reliable and maintainable code.

The Curious History of Regex Anchors: Why `$` and `^`?

2025-01-21

This post delves into the historical origins of using `$` and `^` as line anchors in regular expressions. Tracing back to the QED text editor, `$` initially represented the end of the buffer, later adapted by Ken Thompson to signify the end of a line in regexes. The choice of `^` likely stemmed from the limited character set of the Teletype Model 35 typewriter, with `^` already present in ASCII-67. This wasn't a brilliant design choice but rather a consequence of hardware and character set limitations of that era, becoming a convention in regexes.

Jupyter Notebooks and LLMs: An Unexpected Cost Optimization

2025-01-21

The author used LLMs for coding assistance, initially with a ContinueDev + OpenRouter setup. Costs unexpectedly soared. Investigation revealed that Jupyter Notebook (.ipynb) files contain significant hidden content (code outputs, metadata, base64-encoded images), leading to a large token count and increased LLM call costs. The solution was converting .ipynb files to .py files and removing base64-encoded images. This reduced costs by 94% and latency as well. The post highlights the importance of mindful input when using LLMs and recommends regularly checking costs.

Lessons Learned Building LLM Apps

2025-01-21

This post summarizes lessons learned from building applications using Large Language Models (LLMs). LLMs excel at transforming large amounts of text into concise summaries; they struggle with generating more text than input or relying on their pre-trained data for complex reasoning. Effective LLM applications should provide the LLM with all necessary information, letting the LLM perform text condensation. The author advises against using LLMs for tasks requiring human expertise (e.g., medical diagnosis) and emphasizes that LLMs should augment, not replace, human workers. Avoid using LLMs for tasks that can be done with regular code.

Fixing a Sneaky uname Bug in Apache NuttX RTOS: Static Variables Strike Back

2025-01-21

This post details the debugging journey of a seemingly minor bug in the Apache NuttX RTOS's `uname` command. The initial problem: the commit hash was missing from the output. The investigation led down a rabbit hole, involving inspecting the kernel image, calling `uname` at kernel startup, and disassembling the application. The culprit? A broken static variable (`g_version`) responsible for storing the commit hash within NuttX applications. This unexpected behavior highlighted the importance of thorough debugging in embedded systems, emphasizing that even minor anomalies can signal deeper, more serious issues.

Redis UNLINK vs DEL: A Deep Dive into Internal Mechanics

2025-01-21

Both Redis' UNLINK and DEL commands remove keys, but their internal implementations differ. DEL synchronously deletes keys and frees memory, while UNLINK asynchronously queues the deletion for background processing. UNLINK's 'non-blocking' nature isn't absolute; it calculates the cost of deleting an object: if the cost is less than 64, it deletes synchronously; otherwise, asynchronously. The article delves into the Redis source code, explaining the implementation details of UNLINK and DEL, including key slot calculation, two-phase unlinking, and asynchronous deletion, and discusses the role of LAZYFREE_THRESHOLD.

OpenSSL Rejects QUIC API: A Setback for HTTP/3 Adoption?

2025-01-21

OpenSSL, the most popular TLS library, has rejected adding a QUIC API to its upcoming releases, posing a significant hurdle for widespread HTTP/3 adoption. Despite a community pull request (PR8797) offering the necessary APIs, the OpenSSL management committee decided to build a complete QUIC stack from scratch, a process expected to take several years. This decision has sparked community frustration, as mature QUIC libraries already exist. Microsoft and Akamai created quictls, an OpenSSL fork with the QUIC API, as a workaround. However, this isn't a sustainable solution, leaving the future of HTTP/3 adoption uncertain due to OpenSSL's choice.

Should Go 2 Ditch the `context` Package?

2025-01-21

Go's `context` package, while solving the goroutine cancellation problem, does so at the cost of readability and maintainability, spreading like a virus throughout codebases. The author argues that `context` is overly complex, has too many interface methods, and `ctx.Value` presents numerous issues and is inefficient. They propose that Go 2 should directly address goroutine cancellation at the language level, providing a simpler, more efficient, and less intrusive solution.

Proposal: Essential Effects for C

2025-01-20

This proposal suggests enhancing C's core type system with a type-and-effect system, requiring functions and blocks to declare the effects of their evaluation. This improves metaprogramming composability and simplifies defining MISRA-style restrictions. The system tracks and checks effects but doesn't handle dynamic effect handling. Three main effect groups are proposed: Local (e.g., local writes), Persistent (e.g., non-local writes), and Control (e.g., non-local control transfers). Static effect checking is achieved by assigning type-and-effect to each statement, expression, and function body, discarding local effects to ensure correct ordering. Best practices are suggested, like limiting the magnitude of `mut` and `vol` effects and specifying effect checks for operators and control structures. The goal is to improve C's safety, readability, and composability, especially for metaprogramming and resource management.
