Right, and I suspect as things get more complicated (and you have to ship), abstractions get leaky.

There was also the Java-like syntax for ObjC but I don’t think that ever shipped.

Yup, even with a hard drive the m68k turbo slab was no speed demon. Wasn't too bad on HPPA though.

Still rocking a 2019 (Intel) Mac Pro here, all slots filled with various Pro Tools and UAD DSP cards, SSD, GPU, etc. I'm planning to get as much mileage out of it as I can. I'm sure a Studio would be more performant, but the Thunderbolt to PCIe chassis are not cheap.

I hear you. Actually I read this thread because we’re using jemalloc in an embedded product. The only way I found to work on interesting problems here was to work for myself. (Having said that I think Apple might have some security research in Canberra? Years ago there was LinuxCare there and a lot of smart people. But that was in 2003…)

To some degree. There are _many_ SwiftUI clones that support other frameworks such as Gtk and Windows, with varying states of maturity. Or you can share the business logic and write the UI natively in Swift.

It does like to weasel in if you let it write a commit message, and even after rewriting and force pushing, it seems to hang around on the GitHub contributor list.

Swift actually has excellent C++ interop [1] (compared to other languages, but, I guess, not good enough for Ladybird).

Also things like support for GSS-API pre-authentication mechanisms (so, you can use an arbitrary security mechanism such as EAP to authenticate yourself to the KDC), the new SAnon mechanism, pulling in some changes from Apple's fork, replacing builtin crypto with OpenSSL, etc. Lack of release has been typical OSS lack of resources: no one is paid to work on Heimdal full time.

You also need synchronization to mix sources (common in any production) without incurring the latency and resampling of asynchronous sample rate conversion.

There’s also AES70, or OCA (https://news.ycombinator.com/item?id=46934318). More popular in audio than video, something of a competitor to NMOS (although there are parts of NMOS that were very much inspired by OCA). There are open source C++, Python, JavaScript and Swift implementations as well as some commercial ones.

IOKit was designed to support CoreAudio from the start, cc gvdl.

That is a beautiful piece of industrial design.

XMOS is still keeping the Inmos dream alive, more or less!

Small nitpick: malloc is not a system call.

And Mach 3 vs 2.5. And a 4.4BSD (well, *BSD) user land, although in fairness the original, never released NEXTSTEP 4.0 also had this.

Another approach is swift-java, which uses Swift macros and also supports Panama.

New comment by lukeh in "HP-UX hits end-of-life today, and I'm sad"

lukeh — Fri, 02 Jan 2026 04:46:50 +0000

That’s sad. One of the first pieces of (serious) software I wrote was licensed by HP for bundling with it. Didn’t use HP-UX a lot but it’s a pity we’re asymptoting towards a Unix monoculture.

New comment by lukeh in "Approachable Swift Concurrency"

lukeh — Wed, 31 Dec 2025 02:46:41 +0000

Sequential doesn’t mean reentrancy safe, something which has bitten me a few times in Swift concurrency.
