Isar Aerospace successfully launched its Spectrum rocket from Andøya Space Center in Norway, achieving an elliptical orbit around Earth. The second flight of the two-stage rocket comes after a failed debut mission in March 2025 and marks a significant milestone for European space transportation.

Falsehoods Programmers Believe About LANs

Each entry is phrased as the falsehood. Some of these may sometimes be true and sometimes be false. If I don’t have a RFC 1918 address, I’m not behind a NAT. Okay, only IP, IPX/SPX, Phase IV, AppleTalk, VINES, NetBEUI, or SNA are running on my LAN. MAC addresses are globally unique. (They’re supposed to be, but they aren’t.) The first three bytes are vendor‐unique if it’s a MA-L block.

Finite time blowup for an averaged three-dimensional Navier-Stokes equation (2014)

https://terrytao.wordpress.com/wp-content/uploads/2014/02/circuit-1.png?w=490
The author has formalized the "supercriticality barrier" for global regularity of the Navier-Stokes equation, showing that no abstract approach can establish global regularity without additional assumptions. A modified version of the Navier-Stokes equations with a nonlinearity obeying function space estimates and energy identity leads to finite time blowup.

Visualizing Rust's Vtables: How dyn Trait Works In Memory

https://sofiabelen.github.io/projects/visualizing-rusts-vtables-how-dyn-trait-works-in-memory/Rust_fungus_-_Flickr_-_gailhampshire_hu_f9f62a9c4cc3178c.jpg
The author is comparing Rust's approach to polymorphism with C++'s, highlighting the differences between static and dynamic dispatch. They explore how Rust uses monomorphization for compile-time polymorphism and dyn Trait for runtime polymorphism, which differs from C++'s vtable-based approach.

How Swiss tables work in Go built-in map

https://victoriametrics.com/blog/go-swiss-table-map/preview.webp
Go's Swiss Table implementation for maps uses a triangular probe sequence to find empty slots, allowing for efficient lookup and insertion operations with minimal scanning cost. The new implementation also optimizes memory usage by storing keys together during search and using less padding space when the value array is empty, resulting in faster map operations compared to previous versions.

Researchers scanned a delidded Intel Core i9-14900KS CPU using CT scanner, revealing its internal structure. The scan shows capacitors supporting the silicon circuitry and helps understand power management in high-performance CPUs.

LLMs as a Cognitive Virus

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
Large language models are spreading rapidly through human culture, reshaping information production and use. Their adoption can lead to nonlinear collective transitions with potential consequences for cognitive autonomy.

The revolt of the reader

The author argues that readers can tell when writing is generated by Large Language Models (LLMs) and are increasingly rejecting LLM-authored content, with 78% of respondents in a survey stopping reading immediately upon detecting an LLM. Readers prefer authentic writing over polished but AI-generated content.

America's two largest school districts impose AI moratoriums

The New York City and Los Angeles school districts have implemented new restrictions on AI use in schools, banning student-facing AI in K-8th grade classes and limiting its use for high schoolers. These moves come after intense backlash against previous proposals and reflect growing concerns about the impact of AI on students' mental health.
