Senior Devs Embrace AI Coding More Than Juniors: A Fastly Survey

2025-08-31

A recent Fastly survey of 791 US developers reveals a surprising trend: senior developers (10+ years experience) are more than twice as likely to use AI code generation tools like Copilot and generate over half their code with them, compared to junior developers. This isn't due to laziness, but rather the diverse responsibilities of senior roles. AI helps them prototype faster, though more time is needed for bug fixing. While most senior devs find AI boosts efficiency and enjoyment, juniors prefer traditional coding and are less concerned with energy consumption. The survey highlights the experience advantage in spotting AI-generated errors. Overall, AI coding tools are making the job more enjoyable for over 70% of all respondents.

Can Databases Replace Caches Entirely?

2025-08-31

This post explores the possibility of databases completely replacing caches. While databases offer some caching capabilities like buffer pools and read replicas, caches excel at low-latency data access, especially for specific data subsets and pre-computed data. To replace caches, databases need to address several challenges: efficiently handling numerous read replicas, enabling partial read replicas, prioritizing specific data, and implementing efficient incremental view maintenance (IVM). The author suggests that combining IVM with partial read replicas might eventually allow databases to partially replace caches, but a gap remains.

C++ shared_ptr's Non-Atomic Reference Counting: A Microbenchmark Surprise

2025-08-31

A microbenchmark comparing Rust and C++ data structures revealed unexpected behavior in C++'s `shared_ptr`. In single-threaded environments, GNU libstdc++ optimizes `shared_ptr`'s reference counting to be non-atomic if `pthread_create` isn't imported. This performance optimization, while generally safe, can lead to issues in uncommon scenarios, such as when a dynamically linked library is loaded by a statically linked program. The author investigated other C++ implementations (libcxx and Visual C++) and ultimately resolved the performance discrepancy by referencing `pthread_create` in their benchmark. The discovery highlights the complexities of low-level optimizations and their potential unintended consequences.

Improving Algorithms for Simplifying Geographic Polygons

2025-08-30

This article explores algorithms for simplifying geographic polygons, specifically their convex hulls. The current approach combines the Douglas-Peucker algorithm with polygon offsetting: the polygon is first offset outwards to eliminate details, then simplified using Douglas-Peucker, and finally offset inwards. However, this method isn't optimal for convex features. The author seeks more efficient algorithms to achieve higher-quality geometry at the same size or further reduce size without compromising quality.

dlclose Failure: A Weird Interplay Between Rust and C++ Libraries

2025-08-30

This post recounts a perplexing debugging story: when using `dlclose` to unload a dynamic library, libA was successfully unloaded, but its dependency, libB, unexpectedly remained in memory. Investigation revealed the root cause was thread local storage (TLS) destructors registered in libB. Because the threads didn't exit, these destructors weren't executed, preventing libB from unloading. Enabling logging resolved the issue because the logging library also used TLS, preventing libA from unloading and thus maintaining consistent shared state between libA and libB. This case highlights the importance of understanding `dlclose` behavior and the impact of TLS destructors, recommending the use of the `LD_DEBUG` environment variable for debugging dynamic link libraries.
