The LLM Impact Curve for Software Engineers

This article explores the impact of Large Language Models (LLMs) on software engineers of different experience levels. The author argues that the usefulness of LLMs follows a curve: junior engineers benefit the most, using LLMs to quickly learn and solve problems; mid-level engineers see more limited gains, as LLMs struggle with complex issues; senior engineers see the least improvement, relying more on their experience; while staff+ engineers can leverage LLMs to rapidly create proof-of-concept projects. In short, the impact of LLMs depends on the engineer's experience level and the tasks they work on, making them far from a silver bullet.

From Hours to 360ms: Over-Engineering a Sudoku Solution

2025-02-08

The author tackles a Sudoku puzzle aiming for the highest possible GCD among the nine 9-digit numbers formed by the rows. Initial attempts using the Z3 solver failed to find a solution within hours. The author then employed several optimization strategies: mathematical analysis to reduce the search space, a BFS algorithm, and iterative improvements to the `is_good` function, transitioning from HashSet to bitset and finally leveraging SIMD for vectorized computation. Multithreading and refined thread synchronization reduced the solution time from hours to 360ms, achieving over 1600x speedup. While a hardcoded answer proved fastest, the article showcases how even seemingly simple arithmetic problems offer significant performance gains through meticulous algorithmic optimization.

Hidden Cache Hogs: Why Your Disk Space Is Vanishing

2025-02-08

Many Unix programs cache data in hidden `.cache` and `.local` directories, making it difficult for users to find and clear these large cache files that consume significant disk space. The author witnessed firsthand how graduate students in a shared fileserver environment were baffled by these hidden caches, with hundreds of GBs of disk space being unknowingly consumed. The article calls for developers to store caches in visible directories and suggests that disk space usage tools should explicitly show the contents of these hidden directories to aid in user disk space management.

Correcting Bird's Proof of the Sieve of Eratosthenes: A Proof about Infinite Lists

2025-02-08

This paper corrects an erroneous proof by Richard Bird in his book *Thinking Functionally with Haskell* concerning the Sieve of Eratosthenes. Bird presents a circular, list-based implementation, but his proof hint is flawed. The authors provide a complete correctness proof by introducing new lemmas and appealing to a weakening of Bertrand's Postulate. The connection between this algorithm and David Turner's vision of "Total Functional Programming" is also explored.
