Logica is a powerful open-source declarative logic programming language designed for data manipulation. The language extends the syntax of logic programming to provide intuitive and efficient data manipulation, compiling into SQL for access to SQL engines’ power. Logica utilizes predicates as building blocks rather than functions, simplifying data queries. The language excels in handling complex […]

Joshua Liebow-Feeser shared his team’s approach to encode constraints in the Rust type system for the Fuchsia OS at RustConf. They tackled netstack3, a massive networking stack, with 63 […]
Astronomers using the James Webb Space Telescope have found evidence supporting the controversial Modified Newtonian Dynamics (MOND) theory of gravity, challenging the commonly accepted dark matter theory. MOND proposes that galaxies formed quickly in the early universe without the need for dark matter, contradicting predictions made by the Lambda-CDM model. Although MOND faces challenges in […]
A team of international astronomers recently discovered a unique instance of two galaxies aligning in a way that creates a compound lens system. This discovery challenges previous assumptions about the nature of gravitational lensing in the universe. By utilizing data from the arXiv preprint server and the James Webb Space Telescope, researchers were able to […]
The author discusses the book “Structure and Interpretation of Computer Programs” by Hal Abelson and Jerry Sussman as a seminal work in computer science that heavily influenced their career and research interests. The book introduces programming concepts through Scheme and delves into a variety of advanced topics such as storage management and lazy evaluation. The […]
Daniel Kish lost his vision as an infant but now navigates the world using echolocation, emitting clicks with his mouth to create a mental map of his environment. Kish teaches this skill to blind students, with research showing that echolocation is learnable. To practice echolocation, Kish recommends tuning in to sounds, choosing the right environment, […]
Over 3 billion years ago, a massive meteorite collided with Earth, causing chaos in the oceans but also providing essential nutrients. This meteorite was significantly larger than the one that wiped out the dinosaurs. The impact triggered tsunamis, darkened the skies, evaporated seawater, but also brought up vital resources like iron and phosphorus, supporting microbial […]
A new official logo for CSS has been decided through a community vote on GitHub, following the design language of other web technologies. The logo features the color rebeccapurple (#663399), added to the CSS specification in honor of Eric Meyer’s daughter who passed away at the age of six from brain cancer. Eric Meyer, a […]
In the Linux kernel, a vulnerability has been fixed related to memory leaks when changing remote IPv6 addresses in the mlxsw: spectrum_ipip driver. The issue occurred due to the driver not properly adding the new address to its hash table and removing the old one. The solution involved programming the new address when the configuration […]
