It's not just to enable closed source work though. It can also prevent having to reach out to all contributors if there's a good reason to change the licence in the future.

For example, this is what LLVM is having to do now:

Of course, that gets messy when there are multiple copyright holders: a contributor can use their *own* code in a closed source product, but not others'.

That's why some projects require a "Contributor Licence Agreement", giving an org even more rights than the licence does.

It's also important to note that open source licences only *give* rights to others; the only limitation it places on the copyright holder is that they cannot revoke those rights.

That's why even under the GPL, the copyright holder can still build a closed product on top of it.

This means that a licence violation, in essence, is just a copyright violation.

In other words, if someone e.g. uses GPL'd code in a closed-source product, the offence is the same as if they'd have used non-open source code: a copyright violation.

They were never given permission to use that copyrighted code in a closed-source product in the first place!

Some examples:

- The MIT licence says that people can use your code, provided they do not remove the licence from it.

- The GPL says that people can use your code, provided that, for anything they build on top of it, they give the same rights to anyone they give it to.

You (or your employer) automatically have copyright over everything you write. That roughly means that you can do pretty much everything with it, and others nothing.

At their core, open source licences simply allow others to use what you wrote as well.

Given how open source is everywhere, it's useful to know how open source licences work. Luckily, a rough mental model is not too difficult to form. I'll sketch one out in the replies to this post.

I cracked my phone's screen 😢

However, it's a @Fairphone, so I just replaced the screen with that of a friend's old Fairphone. Took me all of five minutes 😎

The cool thing about working on developer tools is that you get continuous UX research, for free, just by lurking on your issue tracker, forums and/or chat rooms.

Just did my first system upgrade since switching to and... Wow! Not only was it easy (literally: press the "download" button, then the "restart and install" button), but also very fast. Like, I quickly got to 50%, then I went to the bathroom, and as I got back it was done.

And here I'd set aside my Saturday to deal with any potential issues.

A screen reader for Linux (GUI) is being developed in Rust. If anyone knows Rust and would like to help, or to just view the great work taking shape here, see:

Often, the good parts of an approach will be discarded because they are outweighed by the upsides of a newer approach. Then when eventually someone finds a way to get the benefits of the old approach with the new one, some clever cynic will come out of the woodworks lamenting how 'everything old is new again', completely disregarding the advances made in the meantime.

The boy scout rule: leave the code you touch cleaner than you found it.

It sounds attractive, but I'm having second thoughts. What's "clean" isn't usually universally agreed upon, and inconsistently-applied conventions makes those conventions hard to learn for new contributors.

There's two ways to learn abstract tools.

There's rote learning: if I do this, this happens. This'll get you started.

But real understanding happens when you form a mental model of the tool.

Sounds obvious, yet so many engineers use Git every day only knowing `git commit -am`.

(Of course, this is where I should plug my tutorial that helps you form a mental model of Git in ~11 minutes:

My perfect employer:

- aligns with my ideals,
- makes products I'm personally excited to use, and
- has competent colleagues.

There's always been one organisation in particular that always seemed to me to tick all those boxes, so I'm very excited that, starting tomorrow, I'll be joining Mozilla!

@aral Hi! We're familiar with both AGPL and MPL licensing schemes and they are not that different in practice. Please see and Q8-10 & Q17 here Since the frontend part of penpot is significant and running such code constitutes distribution, this potential VC would still have to release all that code (whether unchanged or not) under the MPL.

Apparently now works on Linux too, and I'm excited! It's going to help me solve so many gnarly bugs.

If anyone wants an invite, let me know. (Unfortunately a Google account is required for now.)

I wanted to add some nuance to the whole kerfuffle. In my view, it solves some pretty specific problems that you may or may not have.
