The Tim Cook era is ending on September 1st as hardware boss John Ternus takes the reins. Cook isn't leaving entirely—he'll transition to executive chairman and continue his role as the company's designated 'Trump whisperer.'
Amazon is pouring another $5 billion into Anthropic, but there's a massive catch. In return, the AI startup has committed to spending a staggering $100 billion on AWS, proving that in the AI gold rush, the cloud providers always win.
Yelp is turning its AI assistant into a digital concierge that can actually get things done. You can now ask questions about a restaurant, book a table, and place an order all within a single conversation.
Blue Energy just secured a massive bag to build nuclear reactors in shipyards. By manufacturing them like ships, they hope to tame the notoriously high costs of nuclear power and unlock cheaper financing.
Bruno Gavranović explores a fascinating concept: instead of training LLMs to output a flat list of tokens and parsing them post-training, what if we trained them to produce typed output by construction? It's a deep dive into differentiating through type systems and treating type-level choices as something the network can actually learn.
Wrapping up Agents Week, Cloudflare pulled back the curtain on their internal AI engineering stack. They're routing 20 million requests through their AI Gateway and processing 241 billion tokens, all while using a CI-native AI code reviewer to keep their engineers in check.
If you've noticed a sudden uptick in the phrase 'It's not just [X] — it's [Y]' in articles, you're not alone. This specific sentence construction has become the ultimate telltale sign of AI-generated writing, moving from a subtle clue to a near guarantee of synthetic text.
The latest Git release brings a highly anticipated experimental `git history` command. It allows developers to reword and split commits without the dreaded complexity of interactive rebasing, plus introduces configuration-based hooks for easier management across repos.
A new project is making waves by combining type safety, real-time collaboration, and Conflict-free Replicated Data Types (CRDTs) into a graph database. It's an elegant solution for building local-first, collaborative applications without the usual sync headaches.
A practical guide on using Changesets to handle versioning and changelogs in complex polyglot monorepos. It's a solid read for teams struggling to coordinate releases across different languages and package managers within a single repository.
In today's 'science is wild' news, researchers found that salmon exposed to cocaine and its byproducts in polluted waters tend to roam much more widely. Nature is healing, but apparently, it's also partying.
Microsoft is finally redesigning Teams to move the 'raise hand' button away from the main toolbar. The era of accidentally volunteering yourself during a company-wide all-hands is mercifully coming to an end.
