For context for other readers: this is referring to NAT64. NAT64 maps the entire IPv4 address space to an IPv6 subnet (typically 64:ff9b). The router (which has an IPv4 address) drops the IPv6 prefix and does a normal IPv4 NAT from there. After that, you forward back the response over v6.

This lets IPv6 hosts reach the IPv4 internet, and let you run v6 only internally (unlike dual stack which requires all hosts having v6 and v4).

You can do rollbacks if you’re using something like home-manager on a foreign distribution. It’s just a bit more janky admittedly.

True, but that doesn’t necessarily matter if I can compromise the privileged app instead. I could replace it, modify it on disk, or really any number of things in order to get myself a hook into a privileged position.

Just injecting code in some function call which launches malware.exe would do the trick. Ofc signature checks and the like can help here - but those aren’t a given. There’s any number of ways you can elevate yourself on a system based off of user security if your threat model is malicious processes. Linux (and windows) will stop users from accessing each other’s crap by default, but not processes.

Or: supply chain attacks. Now your official app without any modifications is malicious.

Yep! You can also get pretty far even without containers. At the end of the day containers are just sandboxing using namespaces, and systemd can expose that pretty trivially for services, and tools like bubble wrap / flatpak let you do it for desktop apps. In an ideal world every package would only use the namespaces it needs, and stuff like this would largely not be a concern.

The idea is malware you installed would presumably run under your user account and have access. You could explicitly give it different UIDs or even containerize it to counteract that, but by default a process can access everything it’s UID can, which isn’t great. And even still to this day that’s how users execute a lot of processes.

Windows isn’t much better here, though.

Containers don’t typically have inits, your process is the init - so no extra processes are started for things other than what you care about.

The proper way to handle issues like these is process level permissions (i.e. capability systems), instead of user level. Linux CGroups, namespaces, etc. are already moving that way, and in effect that’s the way windows is trying to head too. (Windows has its own form of containerization called AppContainers, which UWP apps use. Windows also has its own capability system).

As a third party, my understanding is that both the implementation and the protocol are really hard, if not next to impossible to iterate on. Modern hardware doesn’t work like how it did when X did, and X assumes a lot of things that made sense in the 90s that don’t now. Despite that, we cram a square peg into the round hole and it mostly works - and as the peg becomes a worse shape we just cram it harder. At this point no one wants to keep working on X.

And I know your point is that it works and we don’t need too, but we do need too. New hardware needs to support X - at least the asahi guys found bugs in the X implementation that only exists on their hardware and no one who wants to fix them. Wayland and X are vastly different, because X doesn’t make sense in the modern day. It breaks things, and a lot of old assumptions aren’t true. That sucks, especially for app devs that rely on those assumptions. But keeping around X isn’t the solution - iterating on Wayland is. Adding protocols to different parts of the stack with proper permission models, moving different pieces of X to different parts of the stack, etc. are a long term viable strategy. Even if it is painful.

manpages aren’t guides though - they don’t help much in learning new tools, especially complicated ones. They’re comprehensive references, some can literally span hundreds of pages. Useful when you know what you’re doing and what you’re looking for, not great for learning new tools.

This is good for precisely the single user case - potentially malicious services on your system can’t view things they otherwise would be able to, or access resources they don’t need. Even if it’s under the same user.

Linus has stepped away from kernel development before, and probably will again. Life continues on.

Second person excited for bcachefs, I’m planning on swapping over as soon as it supports scrubbing.

Right, but squashed commits don’t scale for large PRs. You could argue that large PRs should be avoided, but sometimes they make sense. And in the case where you do have a large PR, a commit by commit review makes a lot of sense to keep your history clean.

Large features that are relatively isolated from the rest of the codebase make perfect sense to do in a different branch before merging it in - you don’t merge in half broken code. Squashing a large feature into one commit gets rid of any useful history that branch may have had.

Yeah, but phabricator and Gerrit are entirely separate workflows from GitHub, and a lot of people prefer that workflow because it leads to encouraging better histories and reviews. It helps you in getting rid of the “fixed typos” type of commits, while still letting you make larger PRs.

GitHub obviously does let you keep a clean git history, but the code review workflow in GH just doesn’t encourage reviewing commits.

How much of that is what GitHub encourages and how much of that is what Users prefer? Plenty of users seem to enjoy phabricator / Gerrit for code review in practice precisely because of their workflows.

Also, GitHub PRs atleast to me feel like they encourage reviewing changes by the total diff of the entire PR, and not each commit. I don’t want a slog of commits that don’t add any value - it just makes doing things like reverts more annoying. Stuff like Gerrit and phabricator enforce reviews by making you review individual commits / changes / whatever you want to call them and not branch diffs.

The version control system, and all the associated code isn’t tied to any system - yes.

It looks like on blender’s website there’s 6 entities on there, and one of them does seem to be an individual fwiw. Here’s his website: https://aras-p.info/.

The rest all seem to be corporations though - meta, aws, some game company I’ve never heard of, AMD, and epic.

I just checked their financial report for 2022 and it looks like 50% came from patron funding (which looks like entirely companies like Google), 5% from epics grant, and then 10% corporate membership. 20% came from individuals, and the rest from random other miscellaneous things like the blender market. If you search blender foundation annual report 2022, the finances breakdown will be near the end of the slides.

When you make a project with git, what you’re doing is essentially making a database to control a sequence of changes (or history) that build up your codebase. You can send this database to someone else (or in other words they can clone it), and they can make their own changes on top. If they want to send you changes back, they can send you “patches” to apply on your own database (or rather, your own history).

Note: everything here is decentralized. Everyone has the entire history, and they send history they want others to have. Now, this can be a hassle with many developers involved. You can imagine sending everyone patches, and them putting it into their own tree, and vice versa. It’s a pain for coordination. So in practice what ends up happening is we have a few (or often, one) repo that works as a source of truth. Everyone sends patches to that repo - and pulls down patches from that repo. That’s where code forges like GitHub come in. Their job is to control this source of truth repo, and essentially coordinate what patches are “officially” in the code.

In practice, even things like the Linux kernel have sources of truth. Linus’s tree is the “true” Linux, all the maintainers have their own tree that works as the source of truth for their own version of Linux (which they send changes back to Linus when ready), and so on. Your company might have their own repo for their internal project to send to the maintainers as well.

In practice that means everyone has a copy of the entire repo, but we designate one repo as the real one for the project at hand. This entire (somewhat convoluted mess) is just a way to decide - “where do I get my changes from”. Sending your changes to everyone doesn’t scale, so in practice we just choose who everyone coordinates with.

Git is completely decentralized (it’s just a database - and everyone has their own copy), but project development isn’t. Code forges like GitHub just represent that.
