Jon Crispin was allowed to photograph artifacts from the now-closed Willard Asylum for the Insane, where patients’ personal belongings were found in storerooms. The suitcases, trunks, and crates contained ordinary objects that offered glimpses into the lives of the forgotten individuals who lived at the asylum. Photographer Jon Crispin’s detailed photographs of these objects reveal […]
In the early ’80s, music tech faced hardware and software incompatibility issues. Synth pioneers like Moog, ARP, and Sequential Circuits were racing to make synths more affordable and compact. The introduction of CV/Gate system allowed synths to play themselves, changing the music composition game. Dave Smith of Sequential Circuits proposed the Universal Synthesizer Interface, later […]
In the battle over the “flow state” of developers, the need for uninterrupted focus clashes with the necessity of external interruptions. The concept of “flow state” has evolved from its origins with Hungarian-American psychologist Mihaly Csikszentmihalyi in the 1970s to encompass various associations today. Developers often struggle with fragmented thinking that disrupts their flow state, […]
The author discusses their transition from writing visual non-interactive tutorials to creating interactive tutorials on pathfinding, particularly focusing on A*. They mention their interest in flow field pathfinding, explaining that it involves vector fields directing agents to a single destination. The author also touches on distance fields, useful in games and modeling. They discuss updating […]

In the second post of the Zed Decoded series, the co-founders discuss the data structure at the core of Zed: the rope. They explain how ropes differ from strings in memory representation, highlighting the efficiency and performance improvements ropes offer over strings when dealing with large texts and edits. Zed’s rope implementation, known as SumTree, […]
The program uses a genetic algorithm to evolve two-wheeled shapes into cars over generations, similar to BoxCar2D but written from scratch. The seed can be saved and restored, and surprising drawing toggles make the simulation faster. A new population can be generated and a seed can create the same track for competition with friends. Elite […]
Transport for London (TfL) intentionally reduced paper ticket sales on the London Underground by promoting contactless payments. By adding a pop-up message on ticket machines, TfL encouraged customers to use contactless cards instead of buying paper tickets. Not only did this align with TfL’s goal of reducing magnetic stripe ticket sales, but it also saved […]
Intel introduced the 8088 microprocessor in 1979, which IBM adopted for the iconic IBM PC in 1981, solidifying the success of the x86 architecture. The 8088’s 8-bit bus, similar to the 8085, was a key factor in its selection for the IBM PC. The intricate bus cycle structure of the 8088, involving T-states, had multiple […]
