Exercism recently reached a milestone of two million users and 45 million exercise submissions. Despite its popularity, the platform is struggling financially. Efforts to secure funding have fallen short, leading to difficult decisions like letting go of key employees like Erik. However, the community remains strong, with dedicated donors keeping the servers running. The platform […]
Looking up how to compare vectors often leads to the use of cosine similarity, a popular method for determining similarity between embeddings. The process involves calculating the cosine of the angle between two vectors, with 1 indicating identical directions, 0 being orthogonal, and -1 meaning opposites. This method is ideal for comparing high-dimensional embeddings as […]
A micro creative coding playground where you can experiment with changing the source code for classic hexagonal or triangular designs with animation options like scaling and changing opacity. You can also choose to autoplay your creation upon loading. Dive in and see what unique designs you can come up with! (No controversial information provided)
Tetris-SQL is a full Tetris implementation in a SQL query, optimized for Postgres and compatible with various terminals. The game loop, enabled by recursive CTEs, updates the game state based on user input and gravity, rendering the game using RAISE NOTICE. Input handling is done through a table, with dblink ensuring real-time updates. Movement, collision […]
gRPC has become a powerful tool for microservices, offering efficiency and performance benefits, but there are some ugly sides to it as well. The code generated from protobuf definitions can be complex, language-specific quirks can cause issues, and the learning curve can be steep for beginners. The lack of intuitive editor integration and the historical […]
Cristian Adam discussed using Cosmopolitan Libc to compile C++ applications once and run them everywhere, allowing for cross-platform deployment on Windows, Linux, and macOS for x86_64 and arm64. Key points included how Cosmopolitan libc detects the host machine at runtime to provide the right system calls. Challenges were faced on Windows due to Cosmopolitan Libc’s […]
In this paper, the authors explore the acceleration of transformer networks for Large Language Models using hardware accelerators. They provide a thorough survey of research efforts in this area, comparing frameworks based on technology, processing platform, speedup, energy efficiency, performance, and more. One unique aspect is the extrapolation of results to the same technology for […]
Lambda calculus is a mathematical system focused on function abstraction and application, using variables and substitution. The simplicity of lambda calculus revolves around three rules: variables, lambda abstractions, and function applications. Lambda terms in the system follow rules for validity based on variables, abstractions, and applications. Reduction operations in lambda calculus involve alpha conversion and […]
The catalog publication of the Hawking Archive presents a collection of Hawking papers, including a paper by Dr. Katrina Dean and Hawking Archivist Susan Gordon in the Science Museum Group Journal. The Science Museum is home to more than 1,000 objects from Professor Hawking, with a birthday greeting from former US President Bill Clinton. Hawking’s […]
