In princple JJ has non-Git backends, but the only backend they state as being production ready is the Git backend. JJ without the Git interop is more a concept than a reality right now.
I love JJ, and the mental model of source control it presents, and I will continue to use it. However, still needing to "drop down" to Git every now and again to get something done makes it feel very much like a convenient wrapper on top of Git rather than a new SCM.
If Git adds commands to support the JJ workflow, it would be hard to justify having JJ installed any more.
I think there is a strong argument that Gerrit is the current evolution of the patches workflow, many prefer it, and there are a lot of good blog posts explaining why.
I don't know what the justification for emailing patches around is though, that seems needlessly painful in the face of alternatives
Tiny CC doesn't have its own runtime, it uses whatever you specify (falling back to system standard), same as GCC or Clang. For low runtime footprint you are probably better off with one of those two compilers as they generate smaller, more optimised code.
Not right now, it is far too early days. I'm currently working through bugs, and missing stdlib, to get a simple backpropagation network efficient. Once I'm happy with that I'd like to move onto more complex models.
It uses the same trick as Go [1]. The grammar has semicolons, but the tokeniser silently inserts them for ease of use. I think quite a few languages do it now
I tried this with an old iOS only game a few years ago. It is clearly not a heavily used library, but it seemed to work ok
- There was a bug or two I had to patch, but the code is readable, so it wasn't a big deal
- OFString, etc aren't intended to be 1:1 replacements for NSString, etc. This wasn't a real problem. They mostly match, and all I needed to do was write a few categories
- The runtime functions are not compatible at all, but most projects wouldn't touch those
- CoreFoundation and the other C APIs are not there at all, so you'll need replacements
- It is a replacement for Foundation framework, not AppKit, so if it is a GUI app you still have a lot of work to do
Discord if you don't mind something proprietary, Mattermost or Rocketchat if you do, Zulip if you want something slightly different . . . and no doubt many other alternatives
Slack is easy to replace with something cheaper and better on a product or technical level. The network effects are strong of course, but they won't sustain it forever
package.lock is JSON only, Nix is for the entire system, similar to a Dockerfile
Nix specifies dependencies declaritively, and more precisely, than Docker (does by default), so the resulting environment is reproducibly the same. It caches really well and doubles as a package manager.
Despite the initial learning curve, I now personally prefer Nix's declarative style to a Dockerfile
I do the same with Nix as it works for macOS builds as well
It has the massive benefit of solving the lock-in problem. Your workflow is generally very short so it is easy to move to an alternative CI if (for example) Github were to jack up their prices for self hosted runners...
That said, when using it in this way I personally love Github actions
None of this actually matters. If you want to keep your data private, host it on your own hardware. Countries, company policies, etc are all essentially irrelevant
