The invention of the automatic rice cooker in 1955 revolutionized rice cooking, thanks to Fumiko Minami’s dedication and research in perfecting the ideal recipe. Initial attempts by other companies in the 1920s were failures, as their electric rice cookers couldn’t automatically switch off when rice was done. Through innovative techniques using a double boiler and […]

The author paints a vivid picture of a typical day in the Pain Zone, a nightmarish enterprise data warehouse full of nonsensical processes and a culture that values speed over quality. From deciphering gibberish logs to dealing with clueless management, the author’s frustration with the dysfunctional system is palpable. Despite the daily struggle, camaraderie with […]
Hey! I’m Spawek, and my friends and I organized LAN parties for 16 years. These parties include gaming, board games, and intense discussions. Dota 2 is our main game, but team selection was always a challenge due to skill differences. We automated team selection by using Elo ratings to balance teams. We coded during the […]
The author presents a new memory-disk hybrid indexing and search system called SPANN, aimed at providing an efficient solution for approximate nearest neighbor search with reduced costs. By storing centroid points in memory and large posting lists on disk, SPANN guarantees low latency and high recall rates. Using hierarchical balanced clustering for indexing and a […]
In 2023, the author discussed how Shopify’s Ruby monolith’s garbage collector was fine-tuned, implementing out-of-band garbage collection to reduce major collection latency impact. Despite massive latency improvements, the heuristics used were unsatisfactory, prompting the disabling of major GC entirely. A new feature was developed, preventing the automatic triggering of major collection during a request cycle. […]
The author discusses the building of a “Bench Kona” in a shed, using parts from a crashed Hyundai Kona Electric for reverse engineering purposes. They detail the process of wiring together modules on the bench to simplify the complex powertrain of the Kona for an EV conversion. The author highlights challenges faced, such as dealing […]
The finite element method (FEM) celebrates its 80th anniversary in 2021 as a cornerstone of engineering design analysis and scientific modeling. FEM’s impact spans from material mechanics to medical applications, semiconductor design, and beyond, solving problems described by partial differential equations. This paper provides a historical overview of FEM’s development divided into four key time […]
