Was pulled in to a fun customer issue last Friday around disabling RC4 in Active Directory. What happened was, as you can imagine, not good: RC4 was disabled and half their environment promptly started having a Very Bad Day. — Steve Syfuhs (@SteveSyfuhs) March 1, 2021 Twitter warning: Like all good things this is mostly correct, with a few details fuzzier than others for reasons: a) details are hard on twitter; b) details are fudged for greater clarity; c) maybe I'm just dumb.

Spotify Would Prefer You Didn’t Sell Your Own Data for Profit

Spotify has never been shy about the fact that the massive amount of user data it collects is a major part of its secret sauce, from its user-specific Discover Weekly playlist to the annual event that is Spotify Wrapped. But the company, which does everything it can to lock people into long listening sessions and sells ads based on user data, would really prefer it if you didn’t bottle up that sauce and resell it for your own profit.

Amid a nationwide rush by AI companies to build data centers to support their feverish growth, and by many locales to attract them, some cities are saying whoa, not so fast. That's the case in both St. Louis and St. Charles, Missouri, two cities just 30 minutes apart in the heart of the country. On Aug. 22, St. Charles imposed, in a unanimous vote by the city council, a one-year moratorium on new data center construction after news broke about a secretive data center project possibly coming to

Here’s the tech powering ICE’s deportation crackdown

techcrunch.com Lorenzo Franceschi-Bicchierai 2025-09-24 21:00:00

President Donald Trump made countering immigration one of his flagship issues during last year’s presidential campaign, promising an unprecedented number of deportations. In his first eight months in office, that promise turned into around 350,000 deportations, a figure that includes deportations by Immigration and Customs Enforcement (around 200,000), Customs and Border Protection (more than 132,000), and almost 18,000 self-deportations, according to CNN.

I unified convolution and attention into a single framework

The operational primitives of deep learning, primarily matrix multiplication and convolution, exist as a fragmented landscape of highly specialized tools. This paper introduces the Generalized Windowed Operation (GWO), a theoretical framework that unifies these operations by decomposing them into three orthogonal components: Path, defining operational locality; Shape, defining geometric structure and underlying symmetry assumptions; and Weight, defining feature importance.
