Major index providers waived profitability requirements and cut inclusion periods from 90 to 5 days, forcing $30T+ in passive retirement funds to buy SpaceX at IPO prices. Users compare this to organized crime targeting pension funds.

Adafruit received a demand letter from Flux.AI's legal counsel claiming defamatory statements and Computer Fraud and Abuse Act violations. Adafruit accessed only publicly available information due to Flux's server misconfiguration and conducted responsible disclosure.

A user describes their frustrating experience with Gmail's aggressive AI features that automatically summarize emails, generate replies, and constantly prompt them to use AI writing assistance. They feel these intrusive features are disrespectful and suggest they're incapable of writing their own emails. After 16 years with Gmail, they're switching to Fastmail with their own domain, impressed by how quickly Google managed to drive them away despite Gmail's long-term stability.

This course provides comprehensive hands-on training in building language models from scratch, covering tokenization, transformer architecture, training, optimization, and deployment. Students complete 5 intensive assignments implementing components like tokenizers, attention mechanisms, distributed training, data processing, and alignment techniques. Prerequisites include Python proficiency, deep learning experience, and mathematical foundations. The 5-unit implementation-heavy course follows an operating systems approach, guiding students through the entire language model development process including data collection, model construction, training, and evaluation.

This document provides guidelines for AI coding assistants helping CS336 students at Stanford. AI agents should act as teaching assistants that guide learning through explanation and feedback, not by completing assignments. They should explain concepts, review code, help debug through questions, and suggest improvements, but must not write code, give solutions, complete assignments, or implement core components. The goal is preserving the hands-on learning experience while providing educational support.

So-called age verification for social media is spreading globally, framed as child protection but actually laying groundwork for government-controlled internet. Countries are implementing identity verification requirements that eliminate online anonymity, threaten freedom of expression through chilling effects, and enable authorities to track users. This creates censorship machinery where people self-censor knowing posts may have personal consequences. The scope is expanding to VPN restrictions, app stores, and operating systems, with politicians considering broader controls despite knowing social media companies already identify child users.

The author advocates for Janet, a Lisp dialect programming language, highlighting its simplicity with only eight core instructions, easy distribution as native executables under 1MB, superior text parsing using parsing expression grammars instead of regex, excellent subprocess handling, embeddability, immutable collections, powerful macros, and compile-time to runtime value passing capabilities.

Discussion centers on Nvidia's ability to convince major software publishers to create native Arm versions, including games like League of Legends and apps like Adobe Photoshop. Some skepticism exists about whether this represents genuine new development or just marketing existing Arm builds.

A developer reminisces about macOS Leopard's grid-based virtual desktop feature called Spaces, which was replaced in 2011 by Mission Control's inferior horizontal-only layout. Frustrated by this downgrade, they built GridLion, an app that restores grid navigation functionality to modern macOS, allowing users to treat virtual desktops like physical displays with spatial memory and muscle memory navigation.
