Melania Trump's Audiobook Is Narrated by an AI Copy of Herself

Let's get one thing straight: it's hard to be married to the president. From coming up with epoch-defining slogans like "Be Best" to decking the White House halls with bizarre Christmas decor, it's a tougher gig than most of us can imagine. Our current first lady, Melania Trump, is well aware of the challenge after her previous four-year stint in the White House. Notoriously private — or perhaps just too busy to make public appearances — the first lady's life has been shrouded in mystery. Howe

Error handling in Rust

news.ycombinator.com Felix Knorr 2026-02-23 06:28:25

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

Bloom Filters by Example

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
