How we made Haskell search strings as fast as Rust
In this post, we will describe our quest to create Alfred–Margaret, the fastest Haskell implementation of the Aho–Corasick string searching algorithm, which powers string search in Channable. Channable is a feed processing tool where users can define rules to optimize their product feeds. Oftentimes these rules rely on substring searching, for example to categorize products based on keywords that
Algorithms behind Modern Storage Systems
Opening the Box: Diagnosing Operating-System Task-Scheduler Behavior on Highly Multicore Machines Julia Lawall discusses methods for diagnosing operating system task scheduler behavior on highly multicore machines, crucial for performance analysis. She explains the challenges of understanding kernel-level scheduling decisions and shares custom-built tooling for visualizing and analyzing scheduler

Rosetta Code
Rosetta Code is a programming chrestomathy site. The idea is to present solutions to the same task in as many different languages as possible, to demonstrate how languages are similar and different, and to aid a person with a grounding in one approach to a problem in learning another. Rosetta Code currently has 1,315 tasks, 387 draft tasks, and is aware of 968 languages, though we do not (and cann
