Making a StringBuffer in C, and questioning my sanity

news.ycombinator.com Brian Douglas 2025-07-15 20:48:34

I've been writing a lot of C. Whilst doing so I have been questioning my sanity. Am I an awful programmer? You know what, I think I might be. Kudos to all those devs that created monumental feats with C. Because it is not an easy tool to use. That said, I do enjoy writing C, just as long as I don't have a deadline or any business critical software to deliver. But when I say enjoy, I mean enjoyment in the sense of using a sycthe to cut a lawn, whilst my lawnmower watches on. It's lovely using th

BBC Insists Its Disney Partnership Remains Strong in Wake of ‘Doctor Who’ Doubts

gizmodo.com James Whitbrook 2025-07-26 18:10:36

Ever since the latest season of Doctor Who came to a messy end a few months ago, the biggest question on audiences’ minds (among the many questions raised by that finale) is when, or if, we might expect to see the show return to our screens. The further we’ve moved from the season without news other than that there is no news about the BBC renewing its funding and distribution deal with Disney for the series, the more doubts have grown.

A Mental Model for C++ Coroutine

news.ycombinator.com Lu'S Blog 2025-07-28 04:23:57

C++ coroutine is not a library that is ready to go (e.g. std::vector ). It is not even a trait (think of Rust’s Future trait) that library writers or users can implement (or the compiler generates for you in the case of Rust). C++ coroutine is a specification that defines a set of customization points that library writers implement in order to get a functional coroutine. A function supports two operations - call and return . A coroutine (in any language) is a generalization of a function. It su

Here's How to Turn Off Some Annoying iPhone Texting Features

cnet.com See Full Bio 2025-07-29 21:00:04

Texting is one of the easiest ways to stay in touch with friends and family, and if you can't find the right words to use in a text, you can always use an emoji. But you might find some texting features on iPhone to be downright annoying. Some of the biggest culprits include autocorrect and predictive texting. Autocorrect can cut down on the number of typos when you're typing, and predictive texting can make it easy to write a full message in a few quick taps. But when I use these features, mor

Seven Engineers Suspended After $2.3M Bridge Includes 90-Degree Turn

Ever had to make a 90-degree turn on a bridge? No? That’s the problem. In India, seven engineers just got suspended for designing exactly that. A brand-new $2.3 million bridge in Bhopal, India, is going viral—not because it solved traffic, but because it bends at nearly a 90-degree angle. Now, seven engineers have been suspended, a retired official is facing investigation, and the construction firms behind the project have been blacklisted.

The tech behind Rivian’s 2026 Quad Motor truck and SUV — and that kick turn

As Rivian starts accepting orders for its 2026 Quad Motor pickup truck and SUV, customers may initially be enticed by the power and tricks the four motors in these rebooted EVs can unleash. After all, four motors delivering a combined 1,025 horsepower and 1,198 pound-feet of torque — and the ability to accelerate from a standstill to 60 miles per hour in less than 2.5 seconds — is hard to ignore.

(Ed. note: This article was originally published on The CUDA Handbook blog on November 2, 2023.) Every API designer has struggled with the question of how best to propagate errors to their callers, since before the term “API” was invented. Even decades ago (say 30+ years), interface designers knew to separate the error return from the payload, in functions that return other results to their caller.

So I wanted to go over each of these and explain how it’s valid rust. Note that these are not bugs, but rather extreme cases of rust features like loops, expressions, coercion and so on.
