TL;DR summary of stories on the internet
In the debate between precise and conservative garbage collection, the prevailing belief is that precise is always better. However, the argument is not as simple as it seems. Conservative root-finding, where the collector assumes any integer on the stack is a heap address, can actually lead to faster systems in certain cases. Precise collectors may […]

In our work to bypass Windows licensing checks, we uncovered an effective DRM bypass known as “Keyhole.” By exploiting the vulnerabilities in the Client Licensing Platform (CLiP), we were able to create licenses for any Microsoft Store app or Windows edition seamlessly. The process involved manipulating license blocks and utilizing an unobfuscated ECDSA key in […]
In the world of chemistry, open science is gaining traction as more researchers embrace open access, open data, and open peer review. The Chemistry community is slowly adopting methods to share data openly, with progress being made in creating a FAIR (findable, accessible, interoperable, reusable) system. However, challenges such as the dominance of large publishers, […]
LÖVR is a Lua framework designed for quickly creating VR experiences with minimal setup or programming knowledge. It is open source, fast, and compatible with various platforms and devices. Some notable features include cross-platform and cross-device support, beginner-friendly interface, fast rendering capabilities, asset import options, spatialized audio, vector library, physics support, and compute shaders for […]
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 […]
