‘Foundation’ Returns With Its Best Season Yet

gizmodo.com Cheryl Eddy 2026-02-22 15:00:48

Foundation is not a show that lends itself to casual viewing. Its nuances and details, not to mention its constantly shifting settings, mean you must pay close attention to understand what’s happening. It’s also not really a show you can decide to start watching midway through, something to consider ahead of its third season premiere. But the rewards are worth it: it’s wildly entertaining—thanks to its writing, layered world-building, and performances—and while it’s a show that deals with very

Error handling in Rust

news.ycombinator.com Felix Knorr 2026-02-23 00:28:25

On Error Handling in Rust The current standard for error handling, when writing a crate, is to define one error enum per module, or one for the whole crate that covers all error cases that the module or crate can possibly produce, and each public function that returns a Result will use said error enum. This means, that a function will return an error enum, containing error variants that the function cannot even produce. If you match on this error enum, you will have to manually distinguish whi

Performance Debugging with LLVM-mca: Simulating the CPU

Some time ago I had a performance problem that wasn’t easy to explain by just looking at the code, since the version I expected to be faster was actually slower. Since the problem is simple yet illustrative, I am using it as a showcase on how to debug performance issues using llvm-mca. According to it’s documentation llvm-mca is a performance analysis tool that uses information available in LLVM (e.g. scheduling models) to statically measure the performance of machine code in a specific CPU.

Bloom Filters by Example

news.ycombinator.com Unknown 2026-02-22 20:56:09

Bloom Filters by Example A Bloom filter is a data structure designed to tell you, rapidly and memory-efficiently, whether an element is present in a set. The price paid for this efficiency is that a Bloom filter is a probabilistic data structure: it tells us that the element either definitely is not in the set or may be in the set. The base data structure of a Bloom filter is a Bit Vector. Here's a small one we'll use to demonstrate: Each empty cell in that table represents a bit, and the nu

Nick Fernandez / Android Authority It’s been a few weeks since the Nintendo Switch 2 hit shelves, but if we’re being perfectly honest, there’s not much reason to buy one yet. I’ve been revisiting my OG Switch to stave off the FOMO, but I was sad to learn that my left Joy-Con now drifts so badly that Link runs in circles like he’s drunk in Breath of the Wild.

Landmark deepfake law aims to give Denmark's citizens rights over their image, voice, and likeness

Denmark has proposed sweeping legislation to curb the rise of AI-generated deepfakes, positioning itself as a leader in European digital rights protection.

Evaluating Long-Context Question and Answer Systems

For example, technical documentation, novels and movies, as well as multi-document scenarios. Although some of these evaluation challenges also appear in shorter contexts, long-context evaluation amplifies issues such as: Information overload: Irrelevant details in large documents obscure relevant facts, making it harder for retrievers and models to locate the right evidence for
