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 […]
On April 15, 2024, Zilog declared the end of life for the iconic Z80 8-bit CPU, prompting the open-source and hardware preservation community to create a Free and Open Source Silicon (FOSS) replacement. The first fabrication of FOSS Z80 is set for June 2024, utilizing the Tiny Tapeout infrastructure and Guy Hutchison’s TV80 Verilog core. […]
The Cessna 185 Skywagon is a versatile aircraft well-suited for remote areas with minimal airstrips. The Skywagon 185 equipped with floats, skis, and a Robertson STOL kit offers unique capabilities for rough terrains. A tragic accident unfolded due to a violent right-wing stall during take-off, resulting in a fatal crash into Lake Ounasjärvi in Finland. […]
The Ioun Stone of Mastery is a powerful tool that bridges magic and mathematics, granting the wielder control over arcane energies and multidimensional calculations. Einsum, particularly in ML, is a valuable tool for tensor manipulation, offering advantages such as dimension documentation and implicit reordering. The iterative way of using einsum involves nested loops, while the […]
The author reflects on their experiences with Make and its role in simplifying tasks in IT projects. They discuss its use in software compilation, project management, Postfix map files, Python projects, Terraform projects, and even in Hugo blogging. Make is highlighted for its ability to automate tasks efficiently based on dependencies, streamline processes, and make […]
