In this post, the lemma used to prove the fundamental theorem of Galois theory is explored, focusing on understanding and proving the lemma itself. The specific lemma discussed relates to field extensions and automorphisms. A concrete example is provided to illustrate the concept, showcasing how different automorphisms transform elements of the fields involved. The proof […]

Kanban is often associated with whiteboards, sticky notes, and strict workflow columns, but its true essence lies in visual signals. The original meaning of Kanban was a visual signal representing a need or capacity. At Lunar, our office manager, Kasia, created a simple yet effective Kanban system for restocking kitchen supplies. By using an index […]
*nix systems’ terminal usage can be intimidating yet empowering as it provides a direct way to manipulate the system. Text editors are crucial in programming, with Visual Studio Code and Neovim being popular choices. Neovim, a fork of Vim, offers modern features like language server integration and Lua configuration. The evolution of text editors, from […]
Sign up for CleanTechnica’s daily newsletter or follow on Google News for updates. Hydrogen buses are costly compared to battery electric ones, leading transit agencies to question the sustainability of hydrogen buses. Transit agencies excel in operational logistics but are vulnerable to persuasive narratives about new technologies like hydrogen buses. Agencies may overlook the progress […]
Summary: Jess Weatherbed, a news writer, reports that iPhone and Android users will soon be able to exchange end-to-end encrypted RCS messages due to updated RCS specifications by the GSM Association. E2EE prevents third parties from viewing texts. Apple will add support for E2EE RCS messages to their devices in future updates, following the lead […]
A recent success story involving recovering data from the Akira ransomware without paying the ransom is detailed, including the source code used in the process. Multiple versions of the Akira ransomware are circulating, with the encountered variant active from late 2023. The ransomware presents challenges such as encryption relying on four moments with nanosecond resolution […]
Briar is a messaging app for activists and journalists that prioritizes privacy and security. Messages are synced directly between users’ devices, even without internet access using Bluetooth or Wi-Fi. The app can also sync through the Tor network for added protection against surveillance. Briar prevents metadata surveillance by encrypting contact lists, content surveillance by encrypting […]
Concerns about unstable funding for federal statistical agencies such as the Census Bureau and the Bureau of Economic Analysis in Suitland, Md., have raised alarms from officials and data users alike. With increasing budget shortfalls and short-term funding restrictions, some datasets have already ended and reports of reduced participants in surveys are on the rise. […]
The Athena spacecraft’s recent lunar landing attempt was not entirely successful due to a failed altimeter, causing it to skid across the surface and end up in a shadowed crater. Despite experiencing limited power reserves and cold temperatures, the team at Intuitive Machines remained hopeful. Steve Altemus compared the landing to “sliding into second base.” […]
Transformers without normalization layers can perform as well as or better than their normalized counterparts by incorporating a simple and effective technique called Dynamic Tanh (DyT). The DyT layer is a replacement for traditional Layer Norm or RMSNorm layers and is inspired by the observation that layer normalization often generates tanh-like input-output mappings in Transformers. […]
