In this comprehensive web content, the author takes us through the implementation of a data compression program in Haskell using Huffman coding. The program aims to handle arbitrary binary files while maintaining constant memory usage for encoding and decoding. Huffman codes are explained as a method of mapping characters to unique bit sequences for compression, […]

Electricity prices in France have been steadily rising, leading to a focus on optimizing personal consumption. The “Linky” smart meters, controversially feared by some for brain-frying capabilities, allow real-time access to consumption data and are easy to use. Enedis provides API access through MyElectricalData for download in CSV format. Pricing information is available through data.gouv.fr, […]
Property-based testing began with John Hughes experimenting with testing formal specifications for programs during a break in the late nineties. This led to the creation of QuickCheck, a lightweight tool for random testing in Haskell, which later expanded to test mutable state and I/O operations. Quviq AB was founded by John and Thomas Arts in […]
Australian and Indonesian scientists have discovered the oldest known figurative cave art in the Indonesian Island of Sulawesi, dating back at least 51,200 years. The painting features a wild pig and three human-like figures, showcasing the capacity for creative thought in early humans. This find challenges previous beliefs about human evolution, with the painting being […]
North Carolina State University researchers have created a mechanical computer inspired by kirigami that uses interconnected polymer cubes to store, retrieve, and erase data without electronics. These cubes can convey more than binary code and have multiple stable states. The computer design is based on groups of 64 cubes connected with elastic tape that can […]
This web content is a simple engine sound simulator where users can click once to enable sounds. The controls include Space to start, arrow keys to change gear, numbers to shift gears, and B to slow down. It provides a fun and interactive experience for those looking to simulate the sound of different engines. Be […]
The lecture introduces the concept of program synthesis and its evolution from early automation dreams. It delves into the distinctions between program synthesis, compilation, logic programming, and machine learning. The focus is on generating programs that meet semantic and syntactic requirements efficiently, and potential applications in software engineering, end-user programming, data wrangling, reverse engineering, and […]
This content introduces the concept of constraint programming, a method used to solve discrete optimization problems declaratively. Unlike imperative programming, which outlines steps to reach an outcome, constraint programming focuses on describing the desired result through variables and constraints. An example of sharing sweets and a real-world problem of scheduling employees are used to illustrate […]
Trackmania (2020) challenges players to race from start to finish through checkpoints as fast as possible, with the popular Cup of the Day event attracting thousands of players. An AI program’s goal is to master this game format by learning without extensive data or processing power. Previous attempts, like TMRL, used unsupervised learning, while AndrejGobeX […]
Las Vegas’ The Sphere is a massive music and entertainment venue boasting a 16K screen, the highest resolution globally. It showcases unique experiences like Darren Aronofsky’s film Postcard from Earth, offering impressive visuals and 4DX-style effects. Despite high prices and some shortcomings in the film itself, the immersive illusion created by The Sphere is engaging. […]
