I was looking into this. The M5 performance cores can be scaled down to match efficiency cores in performance and power usage. I believe they lower the clock speed, limit how much work is done in parallel on each core, and limit how aggress

The guy you relied to wrote the locking code. If you’re so certain they’re doing it wrong, would it not be easier to just prove it? It’s only one file, and they already have benchmarking set up

JpegXL and AVIF are comparable formats. Google argued you only needed one, and each additional format is a security vulnerability.

> I am curious if the equation of CPU-determined graphics being faster than being done on the GPU has changed in the last decade If you look at Blend2D (a CPU rasterizer), they seem to outperform every other rasterizer including GPU-base

I hope with Alan Dye now out of Apple they will revisit a lot of what just happened. There’s been a lot of places where things have just become worse

Since you’re on the topic, what ever happened to the multi threading stuff you were doing on JSC? Did it stop when you left Apple? Is the code still in JSC or did it get taken out?

iOS used to do this using the Cassowary constraint solver pre-SwiftUI. It’s the worst thing to work with. So much code turning on and off constraints, dynamically adding constraints when you have new views. And that’s before you get into co

This basically makes a rust server to do the routing, then uses the Boa JS engine to evaluate the JS to handle the route With this approach, you might be able to do some multithreading to improve the throughput However, each request is almo

I do iOS dev as a side-hobby too ( https://jacobdoescode.com/ ) People are right it isn’t anywhere near a salary, but I have fun and it has opened job opportunities too For marketing, I found /r/Apple very receptive
