I made a real-time C/C++/Rust build visualizer

news.ycombinator.com Unknown 2025-11-21 12:06:55

August 13, 2025・6 minute read Many software projects take a long time to compile. Sometimes that’s just due to the sheer amount of code, like in the LLVM project. But often a build is slower than it should be for dumb, fixable reasons. I’ve had the suspicion that most builds are doing dumb stuff, but I had no way to see it. So I’ve been working on a cross-platform tool to help speed up builds (you can try it, see below). It works with any build system or programming language (Not just C/C++).

Chefs Advise: Don't Waste Your Money on These 20 Pointless Kitchen Tools

Kitchen gadgets come in all shapes and sizes but that doesn't mean all of them are actually useful. While essential kitchen utensils get used constantly and can speed up your cooking process, some options are just going to take up space and end up collecting dust. Choosing versatile options like a quality knife, or kitchen shears, means that you'll build skills and ensure those tools get used on a regular basis. Instead of chasing every buzzy new appliance, it pays to stick with gear that's fun

Samsung Galaxy Z Fold 7 Samsung's Galaxy Z Fold 7 might be headed the wrong way on price, but it's going in the right direction for everything else. It's both slimmer and more powerful than any Fold before it, fitting the same battery and a new chipset into a body that's barely over four millimeters when open. I'd love to see one or two S Ultra-tier improvements, but there's no denying this is the foldable Samsung has wanted to make for years. I’ve been on board with foldable phones since the s

Cregger revealed to io9 recently that he had, at one point, written a chapter centered on Gladys, but eventually cut it. “In an earlier draft of the script I had given her her own chapter,” Cregger told io9. “It was a

We Keep Reinventing CSS, but Styling Was Never the Problem We’ve been building for the web for decades. CSS has had time to grow up, and in many ways, it has. We’ve got scoped styles, design tokens, cascade layers, even utility-first frameworks that promise to eliminate bikeshedding entirely. And yet, somehow, every new project still begins with a shrug and the same old question: “So… how are we styling things this time?” It’s not that we lack options.

And this time, it’s especially good news for Apple.

For anyone born too late to have regularly used one, a floppy disk is a magnetically coated, flexible polyester disk encased in a protective shell.
