Optimizing a Math Expression Parser in Rust

Optimizing a Math Expression Parser in Rust Optimizing a Math Expression Parser in Rust Table of contents In a previous post I explored how to optimize file parsing for max speed. This time, we’ll look at a different, self-contained problem: writing a math expression parser in Rust, and making it as fast and memory-efficient as possible. Let’s say we want to parse simple math expressions with addition, subtraction, and parentheses. For example: 4 + 5 + 2 - 1 => 10 (4 + 5) - (2 + 1) => 6 (1

I’ve Used T-Mobile’s 5G Home Internet for 3 Years: Here’s What I Love and What I Hate

Albuquerque, New Mexico: home of green chiles, 300 days of sunshine, the International Balloon Fiesta... and achingly slow internet. Of the top 100 cities in the US, Albuquerque ranks 85th, according to data from Ookla. (Disclaimer: Ookla is owned by Ziff Davis, the same company that owns CNET.) Home internet was a two-horse race in Albuquerque for years: CenturyLink DSL and Xfinity cable. I spent decades on DSL, watching my internet speed tests march slowly up to a maximum of 20 megabits per se

German court rules Meta tracking technology violates European privacy laws

A German court has ruled that Meta must pay €5,000 ($5,900) to a German Facebook user who sued the platform for embedding tracking technology in third-party websites — a ruling that could open the door to large fines down the road over data privacy violations relating to pixels and similar tools. The Regional Court of Leipzig in Germany ruled Friday that Meta tracking pixels and software development kits embedded in countless websites and apps collect users’ data without their consent and viola

Generic interfaces

Generic interfaces Axel Wagner 7 July 2025 There is an idea that is not obvious until you hear about it for the first time: as interfaces are types themselves, they too can have type parameters. This idea proves to be surprisingly powerful when it comes to expressing constraints on generic functions and types. In this post, we’ll demonstrate it, by discussing the use of interfaces with type parameters in a couple of common scenarios. A simple tree set As a motivating example, assume we need

Don't cancel Netflix yet: I used these secret codes to unlock shows I didn't know existed

Adam Breeden/ZDNET Netflix wasn't the first streaming platform, but it was the first to make video-on-demand mainstream. Fourteen years ago, as it phased out its mailing service, it took a massive bite out of the global market. Also: This 30-second fix made my Roku TV run like new again (and why it works) Remember that? Physical DVDs showing up in your actual mailbox -- the one at the end of your driveway (or your hallway)? To my surprise, that was still actually a thing up until late 2023. W

Meta offered Apple’s head of foundation models more than $200M to jump ship

Earlier this week, Ruoming Pang, the executive who until recently led Apple’s AI models team, left the company to join Mark Zuckerberg’s Meta Superintelligence Labs, or MSL. Now, as reported by Bloomberg, we know just what it took to lure him away. An offer Pang couldn’t refuse (and that Apple couldn’t match) According to the report, Meta offered Pang one of the largest packages seen (yet) in the AI brain-poaching wars, with the promise of more than $200 million spread out over multiple years.

The End of the Internet As We Know It

The internet as we know it runs on clicks. Billions of them. They fuel ad revenue, shape search results, and dictate how knowledge is discovered, monetized, and, at times, manipulated. But a new wave of AI powered browsers is trying to kill the click. They’re coming for Google Chrome. On Wednesday, the AI search startup Perplexity officially launched Comet, a web browser designed to feel more like a conversation than a scroll. Think of it as ChatGPT with a browser tab, but souped up to handle y
