Continuations (“function calls”) reduce the amount of optimisations you can do around memory - both space wise and computationally

It can be both

Legacy - they’re blocking

The only people I know with full EVs don't have driveways. It's not really an issue - you can charge when you go grocery shopping

Apple has a third party sell them - https://selfservicerepair.eu/en-GB/home

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 …

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 benchm…

I think all UK airports have easy to find water bottle refill stations

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 see…

Safari probably is that size because WebKit is a system framework, so it’s just the size of the UI code

The train now approaching platforms 1 and 2 is the…

The signals bounce off the tunnels a lot

> Why do you think the padding as a percentage is relative to the width of the parent? Do you think it was a happy accident? I don't think so, it was purposefully put there in the …

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

I had a blog post on something similar (but less sophisticated) https://jacobdoescode.com/2025/05/18/precomputing-transparen...

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 constraint…

This might actually happen indirectly. Kagi’s new browser uses WebKit. macOS only now, but eventually it’ll come to windows

I do a few apps that get about this, but the one most interesting to the audience here is a scientific calculator for iOS, iPadOS and macOS https://jacobdoescode.com/technicalc One…

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 multithrea…

The reactors will also be cast in the UK by Sheffield Forgemasters

Every update slows your phone down temporarily, because there’s background processing that goes on for a while after. That’s always been the case

Upgraded my 12 mini. Performance is fine. Battery life is as it always was
