The Parker Solar Probe captured footage of massive “vortex-like structures” in the sun’s outer atmosphere, possibly caused by a coronal mass ejection interacting with the solar wind. The rare vortices, known as Kelvin-Helmholtz instabilities, offer new insights into understanding and predicting potentially harmful CMEs on Earth. The probe, constructed with a carbon heat shield, will […]

The author delves into the history and evolution of Source Control Management (SCM) Systems, highlighting the significant impact of systems like SCCS in the 70s and RCS in the 80s. The focus is on detailing the specific limitations and improvements of these early systems, such as the use of deltas, adding comments to commits, and […]
Loki is an open-source tool that automates fact verification by breaking down lengthy texts into individual claims, filtering out vague statements, generating queries, crawling for evidence, and verifying claims. It is beneficial for journalists, researchers, and anyone interested in verifying information. This tool includes components like Decomposer, Checkworthy, Query Generator, Evidence Crawler, and ClaimVerify. Users […]
In this paper, we present DARE, a technique that allows Language Models (LMs) to acquire new capabilities by assimilating parameters from similar models without retraining or GPUs. DARE sets delta parameters to zeros without impacting the abilities of Supervised Fine-Tuning (SFT) LMs, helping to sparsify parameters and merge multiple models into one. Experimental results show […]
The author bids farewell as PiVPN, a project filled with nostalgia and gratitude, comes to an end. Created to simplify VPN setup and management, PiVPN has now served its purpose with its mission accomplished. The journey was made possible by the collaboration of 84 contributors and the dedication of the author’s team. The repositories will […]
In 1960, Gene Amdahl of IBM was tasked with creating the System/360 mainframe computer family, which revolutionized the industry. The System/360 allowed for different speeds and peripherals while running the same software, leading to its success as IBM’s most profitable product. Amdahl’s architecture influenced future IBM mainframes and continues to impact current models. The software, […]

This web content summarizes details and sources related to Postgres table-level and row-level locking, as well as zero-downtime migrations using Django and Postgres. The information provided is derived from tests and can be considered true to some extent. One notable test involves determining the locks taken by an arbitrary SQL statement through runtime inspection. The […]
Summary: This content delves into compiling Fortran code for WebAssembly to run in web browsers. Fortran, a decades-old language, still finds use in scientific and engineering applications due to its efficiency. Various methods, like Dragonegg, LFortran, and LLVM Flang, are discussed for compiling Fortran to WebAssembly, each with its drawbacks. The process involves modifying LLVM […]
Sixty-five years ago, NASA announced its first astronauts, known as The Mercury 7, who went through a grueling selection process before being unveiled to the press. A group of seven individuals were chosen based on their military background, physical condition, and flight experience. The astronaut lineup included unique personalities such as the witty Gordon Cooper […]
