Rails on SQLite: new ways to cause outages

Rails on SQLite: exciting new ways to cause outages This post was originally given as a talk for Friendly.rb. The slides are also available. Between Litestack and the Rails 8 trifecta of Solid Cable, Solid Cache, and Solid Queue, it’s easier than ever to spin up a Rails app that doesn’t need a database service, or a redis service, or a file storage service. It’s great to simplify things, but even after 20 years of deploying Rails apps I was still caught out by some of the ways things are diffe

A trove of internal documents leaked from a little-known Chinese company has pulled back the curtain on how digital censorship tools are being marketed and exported globally.

Alphabet's health tech subsidiary Verily used the health data of more than 25,000 patients without authorization and actively covered up those violations, a former company executive alleges. The executive, Ryan Sloan, claims Verily fired him after he discovered breaches of the Health Insurance Portability and Accountability Act, or HIPAA, and reported his concerns to the company's senior management.

Adjacency Matrix and std:mdspan, C++23

news.ycombinator.com Unknown 2025-10-27 21:14:20

In graph theory, an adjacency matrix is a square matrix used to represent a finite (and usually dense) graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not, and in weighted graphs, they store the edge weights. In many beginner-level tutorials, adjacency matrices are implemented using vector of vectors (nested dynamic arrays), but this approach has inefficiencies due to multiple memory allocations. C++23 introduces std::mdspan , which provides a more efficient

Tonverk is Elektron’s new polyphonic sample mangler and groovebox

theverge.com Terrence O'Brien 2025-10-31 16:36:45

Elektron has built a cult-like following over the years with its unique and, at times, esoteric take on electronic musical instruments. On paper, Tonverk is a seemingly over-powered sampler that continues that tradition. It’s the rare piece of hardware capable of creating multisampled instruments on its own. It turns a single sample track into a nesting doll of multiple samples. And it’s loaded with an absolutely absurd amount of routing and audio processing features. Tonverk is certainly capabl
