In April 2026, a blog entry discusses the development of "Pizza Legacy," an open-source remake of the 1994 DOS game "Pizza Tycoon." The author highlights the game's close-zoom street view, where cars navigate the roads, creating a vibrant city atmosphere, despite occasional bugs. Starting in 2010, the author struggled for 14 years to implement a satisfactory car movement system, encountering issues with overly complicated designs. A 2017 attempt involved intricate systems for tile and car

Absurd is a durable workflow system designed for PostgreSQL that simplifies the complexities of executing long-running tasks by utilizing stored procedures within the database. It requires only a PostgreSQL database and a single schema file (absurd.sql), eliminating the need for additional services, message brokers, or coordination layers, which keeps SDKs lightweight and language-agnostic. The system allows tasks to run for extended periods without losing their state. Tasks are placed on a queue, picked up by workers, and are divided

The Kalman Filter is a crucial algorithm that estimates and predicts a system's state amid uncertainty, making it valuable in fields like object tracking, navigation, robotics, and control. It enhances stability by reducing noise and compensating for factors such as hand jitter in applications like computer mouse trajectory estimation. Beyond engineering, it is also employed in financial analysis to identify stock price trends and in meteorology for weather forecasting. Despite its fundamental simplicity, the Kalman Filter is often explained through complex mathematics, which can mis

The Kalman Filter is an algorithm used to estimate and predict system states amidst uncertainty, such as measurement noise or external factors. It is widely utilized in fields like object tracking, navigation, robotics, and control, helping to stabilize motion paths, like that of a computer mouse, by reducing noise and jitter. Beyond engineering, it also finds applications in financial market analysis for detecting stock trends in noisy data, and in meteorology for weather predictions. However, many educational resources present the Kalman Filter with

The author expresses a long-standing fear of floating point arithmetic, stemming from a failed attempt to implement it five years prior. Initially believing that their ability to use floating points equated to understanding them, they realized this misconception hindered deeper comprehension. Now, they are determined to tackle the topic again, aiming for a thorough understanding rather than just surface knowledge. The author plans to dedicate ten days to studying floating point representation, assuming the reader has some basic familiarity with the concept. They introduce specific definitions relevant to

The dialogue revolves around a conversation between two beings discussing the nature of an intelligent species they have discovered. One insists that this species is entirely made of meat, asserting that they are the only sentient race in that sector. Despite skepticism from the other being, who questions how meat could create machines or communicate, the first being clarifies that the creatures are fully conscious and capable of thought, emotion, and communication, all of which are generated by their "meat" brains. The conversation highlights the absurd
