The X Window System uses a text file called rgb.txt to map color names to RGB values. This file was included with X11 installations and is typically found in the directory <X11root>/lib/X11/. While the color names are widely used by graphic designers, there is no standardization, resulting in inconsistencies and some colors having multiple names. The list's origins trace back to X10 release 3 in 1986 and evolved through several X11 releases, eventually reaching a comprehensive version

The content discusses the use of memoization in Ruby, particularly regarding hash lookups. While memoization can optimize slow operations by storing results in instance variables, its application might not be necessary for simple hash lookups, as Ruby hashes are already well optimized. The author benchmarks a Setting class with both a standard method and a memoized version. The results show a slight speed improvement (1.31x faster) for existing keys, but a negligible performance gain (less than 20 nanoseconds) unless

Running database migrations during a blue-green deployment is crucial for achieving zero downtime, with the database acting as a key coordination point. In a production scenario, migrations are executed prior to deploying new application code, ensuring database schema compatibility with both the old and new versions. Using AWS ECS and CodeDeploy, migrations run as isolated, one-off tasks that require proper resource allocation due to their resource-intensive nature. Managing statement timeouts is vital, particularly in PostgreSQL, where long-running migration operations may exceed default time

The author reflects on their experience developing embedded software dominated by state machines, which made understanding and maintaining the code challenging due to its non-linear flow. They question whether there is a clearer way to express control flow, especially since the project couldn't use an RTOS, limiting conventional concurrency management. Inspired by their familiarity with coroutines in languages like Python and JavaScript, they propose using a coroutine pattern to achieve concurrency without the need for an operating system. They introduce a toy example involving an LED blinker that

Google Chrome is transitioning from Manifest Version 2 (MV2) to Manifest Version 3 (MV3), which involves changes that negatively affect adblockers by removing the webRequestBlocking permission that allows extensions to dynamically block requests based on content. This shift raises concerns since Google generates significant revenue from ads. In 2023, a bug was discovered that enabled webRequestBlocking to function in MV3, which the author humorously refers to as their funniest find. The bug relates to the way Chrome
