Not sure what you meant by that, you always could `mmap` files into memory on iOS. Back in the 32 bits days there was a ~700 MB limit due to the address space, but there aren't anymore nowadays with 64 bits. If `didReceiveMemoryWarning` is called on your app, then you need to free resident memory but the kernel will take care of dumping file-backed memory pages for you.

I’m not sure if it changed, but last time I heard HN was running on FreeBSD: https://news.ycombinator.com/item?id=16076041

In the case of FreeBSD, Sony used it as the base for the OS on PlayStation since PS3.

The Labour Files examines thousands of internal documents, emails and social media messages to reveal how senior officials in one of the two parties of government in the UK ran a coup by stealth against the elected leader of the party.

- No! No, this is absolutely not that trademark character. Just a unitard with the systems of the human body on it. On a guy.

It's before. You can code sign and verify macOS binaries with any certificate you wish, including a self-signed one (useful in case you want your private iTerm fork). Note the plugin should be signed with the same certificate as the iTerm app [1], just using a paid account won't work.

Heroin is close to fent in lethality, and oxycodone is next in line [2].

My point is: if you're comfortable working with a slightly obscure microcontroller, then you won't have much problems. LLVM supports WebAssembly out of the box, so it mostly feels like programming for one of those.

Anecdotally: we run a large Rust app in under 1 MB of WebAssembly at Zscaler.

In case you absolutely do not care for WASI but love WebAssembly for the web.

I'd start with that, it's an obvious red flag. Switching between both should create huge differences. Also look into `wasm-opt` from the Binaryen project for post-link optimizations, `wasm-ld` from LLVM isn't that great at DCE.

OpenGL ES 2.0 is probably the most portable GPU rendering API there is, it pretty much runs anywhere. That said, using Metal or D3D should definitely bring noticeable improvements, especially when it comes to memory bandwidth (eg. on Metal no need to send pixels to the GPU memory for atlas-based text rendering).

They removed the hypervisor framework in addition to the kernel support for virtualization a few months ago unfortunately.
