Tell HN: Help restore the tax deduction for software dev in the US (Section 174)

This project had its own kernel, but it also seems to be able to use the firecracker one. I wonder what the advantages are. Even smaller? Making use of some apple silicon properties?

Has anyone tried it already and is it fast? Compared to podman on Linux or Docker Desktop for Mac?

Does this enable running containers next apps to iOS and MacOS downloaded from AppStore?

Container runs OCI (docker) compatible by creating lightweight VMs.

This repository houses the command-line interface which is powered by containerization[0], the Swift framework wrapping Virtualization.framework to implement an OCI runtime.

I am going to show my ineptitude by admitting this, for the life of me I couldn’t get around to implement the Mac Os native way to run linux VMs and used vm-ware fusion instead. [0]

I’m glad this more accessible package is available vs docker desktop on mac os or the aforementioned, likely to be abandoned vmware non enterprise license.

VMware Fusion is a perfectly good way of running VMs, and IMO has a better and more native UI than any other solution (Parallels, UTM, etc)

How actually is Swift as a Rust alternative? Is it feasible?

The only gripe I remember with it is that all its APIs are weird.

Like instead of normal names, you have Apple-legacy-names for methods/classes.

I can't speak to performance since I don't really race languages. But as far as feel and what not, it is very similar. But there is also a pretty good overlap in people who worked on Rust and people who worked in Swift. Graydon worked on both. So Swift has a lot of similarities with Rust. The way I usually word it is, Swift is like having C# with mostly everything you like about Rust.

I believe a lot of the legacy names come from when your interfacing with platform APIs like UIKit and such if you have to and they haven't quiet gotten a bump from their Objective-C APIs to have more swifty-APIs.

Depends on what you're doing. If you want to write systems code, Swift is very allocation-happy and will probably not be the best fit. They're trying to make an embedded Swift, but progress is pretty slow, since that's not going to be something that gets anyone promoted.

If you just want to write A Thing, then it's up to your individual taste, what's available in the ecosystem, etc.

Is it smart to call the implementation after the category, or am I misunderstanding what is going on? Surely they won't be able to trademark this?

It's not a product; it's a command line tool that's (more or less) part of the OS. It doesn't need a fancy name.

Should probably merge with https://news.ycombinator.com/item?id=44229348

I disagree, they are different, and that (containerization, not container here) is the more novel/interesting one imo. It'd be nice to focus the discussion more (though at present there are many confused comments there that think they're discussing the container tool).

dang · 53m ago

Whoops, I merged them but you've persuaded me to unmerge them. This will take a bit of time.

Edit: reverted!

Oh, like OP I didn’t see the difference. I believe the difference is:

Container is a CLI tool

Containerization is a framework

OJFord · 4h ago

Yes, container is like `docker` CLI: 'I am a developer and I want to run a container'; containerization is for packaging OCI image container sidecars into Swift .apps - you could distribute your app with postgres 'built in' (but running as a container), user doesn't need to ensure it's installed and running separately or anything.
