Yes, I should not have said “impossible”: nothing is ever impossible to breach. All you can donis to make a breach more expensive to accomplish.

Those separate tpm chips are getting rare… most of the time they are build into the CPU (or firmware) nowadays. That makes sniffing harder, but probably opens other attack vectors.

Anyway: Using a TPM chip makes it more expensive to extract your keys than not using such a chip. So yoj win by using one.

A TPM is a very slow and dumb chip: It can hash data somebody sends to it and it can encrypt and decrypt data slowly. That’s basically it. There is no privacy concern there that I can see. That chip can not read or write memory nor talk to the network.

Together with early boot code in the firmware/bootloader/initrd and later user space that chip can do quite a few cool things.

That code will use the TPM to measure data (create a hash) it loads before transfering control over and then unlock secrets only if the measurements match expected values. There is no way to extract that key on any system with different measurements (like a different computer, or even a different OS on the same computer). I find that pretty interesting and would love to use that, but most distributions do not offer that functionality yet :-(

Using the TPM to unlock the disks is just as secure as leaving the booted computer somewhere. If you trust the machine to not let random people log in, then TPM-based unlocking is fine. If you do not: Stay away.

Extracting the keys locked to an TPM is supposed to be impossible, so you do not need to worry about somebody stealing your keys. That alone makes TPMs very interesting… your own little FIDO tocken build right intomyour machine:-)

Not only that: It protects your data. The Unix security model is unfortunately stuck in the 1970s: It protects users from each other. That is a wonderful property, but in todays world you also need to protect the users from the applications they are running: Anything running as your user has access to all your data. And on most computer systems the interesting data is the one the users out there: Cryptogrqphic keys, login information, financial information, … . Typically users are much more upset to loose their data than about some virus infecting the OS files, those are trivial to fix.

Running anything as anlther user stops that application from having access to most of your data.

The same happens with any of the new immutable distributions. It’s just less effort as you do not need to do the nix configuration dance anymore.

Any of the many immutable distros (vanilla os, fedora silverblue, bluefin, aeon, endless os, pure os, …) will all obviously work.

Most of your customizations will live in your home directory anyway, so the details of the host OS do not matter too much. As long as it comes with the UI you like, you will be mostly fine. And yku said you like gnome, that installs many apps from flathub anyway and they work just fine from there.

For development work you just set up a distrobox/toolbox container and are ready to go with everything you need. I much prefer that over working on the “real system” as I can have different environments for different projects and do not have to polute my system with all kinds of dependencies that are useless to the functionality of my system.

NixOS is ofmcourse also an option and is quasi-immutable, but it is also much more complicated to manage.

Github login does not help much… devs are on github, not on random forgjo instances. That’s where they see your project. Github is also where they put their fork of your project when they play with it. They will write comments using github markdown and won’t care whether that renders correctly or not in your forge.

And it is where they will report issues and open a PR. It is annoying, but it is how it is. When you ask them to open the PR elsewhere they complain sinde they need to set up an account there and copy ssh key and similar things. You need a very dedicated contributor to go through with all that… especially if it is just a few lines of drive-by fixes.

I never said that you can not run a project elsewhere, my point is that you will get way more interaction on github.

Try pushing your project to github and compare the interactions you get from both forges.

That unfortunately requires setting up email… I have not bothered doing so on my boxes in a very long time.

The biggest factor to me is developer attention. I had a project on gitlab and pushed a README.md with a link to the gitlab instance into github. I got about 10 times more reactions from github, incl. PRs (where the person had grabbed the code from gitlab and did a PR on github anyway) – even in this setup. Mirroring a project to github tilts that even further.

Not being present on github means a lot less users and contributors. As long as that stays this way there is no way around github.

I hope federated forges can move some attention away from github, making other forges more visible… but I am not too optimistic :-(

The blocking certain countries is a US legal thing. It effects any forge in the US and probably in more areas close to the US. As soon as a forge gets big enough to show up on the radar of government orge they will need to do similar blocking.

You can not really blame github for that part.

Rustfmt is not very configurable. That is a wonderful thing: People don’t waste time on discussing different formatting options and every bit of rust code looks pretty identical.

Why would they need to share ssh keys? Ssh will happily accept dozens of allowed keys.

It gets rid of one more SUID binary. That’s always a win for security.

Sudo probably is way more comfortable to use and has way more configurable, too – that usually does not help to make a tool secure either:-)

When I last checked (and that is a long time ago!) it ran everywhere, but did only sandbox the application on ubuntu – while the website claimed cross distribution and secure.

That burned all the trust I had into snaps, I have not looked at them again. Flatpaks work great for me, there is no need to switch to a wannabe walled garden which may or may not work as advertised.

It’s just a git repo, so it does not replace a forge. A forge provides a lot of services around the repo and makes the project discoverable for potential users. None of that is covered by this thing.

I frankly see little value wrapping a decentralized version control system into layers of cryptography that hides where the data is actually stored (and how long it is going to be stored). Just mirror the repo a couple of times and you have pretty good protection against the code going offline again and you are done. No cryptography needed, and you get a lot of extras, too.

If you do not like github: Use other forges. Self-host something, go to Codeberg or sourcehut, use something other than git like pijul or fossil, or whatever tickles your fancy. Unfortunately you will miss out on a lot of potential contributors and users there :-(

GPL effects “derived works”. So if your code is derived from proprietary code, you can not use GPL, as you would need to re-license the proprietary code and you can’t do that (assuming you do not hold the copyright for the proprietary code). LGPL and permissive licenses are probably fine though.

Now what exactly is a “derived work”? That is unfortunate up to interpretation and different organizations draw the line in slightly different places. We’d need people to go to court to get that line nailed down more firmly.

Why don’t you download the latest release/nightly from github and unpack it somewhere?

Then how do you not see the point of a distributed sourceforge?

But this is no forge, it is just a git repo.

Again, have you even opened the webpage?

Yeap, I even put a repo into it. That’s why I am so certain that it is useless.

Hosting a git repo is not a problem. Having an discoverable forge is. And this does not help with that in any way.

So github is not a problem?

Something can not be a solution independent of whether or not something else is another problem or not.

And regarding crypto, show me where in the code it forces you to use crypto. Show me the rad command that inhibits you from doing a normal git operation by bringing up crypto.

There is lots of needless crypto(graphy) going on all over the place. It is entirely useless for code hosting in a git repo.

No, I would prefer a world where not everything is concentrated on github, but that is the world we have to work with:-)

But how does this address any of the problems you brought up?

Do you think a project will be more discoverable when you say: “Clone foo/bar from github” or when you say “install this strange crypto-BS, then clone rad:xyhdhsjsjshhhfuejthhh just like you normally would”?

Apart from discoverability you get a known workflow for contributors, a CI and a bug tracker. Coincidently those make it hard for projects to switch away from github… how does this address any of that? “Use this workflow, which is even wierder than any of the other github alternatives!” and “just set up a server yourself”?

Sorry, this is just yet another crypto-bro solution in search of a problem. Technically interesting, I’m give you that, but useless.

Serious question: What is the point?

Just push into half a dozen mirrors and you are pretty censorship resident without the crypto voodoo put on top of git.

Github has one huge value: Discoverability of a project. This is even worse than hiding your project in one of the smaller forges… nobody can remember the mess of letters you need for this.
