Why do I name projects with a website in the path?

If your package has the exact same import path as someone else's package, then someone will have a hard time trying to use both packages in the same project because the import paths are not unique. So long as everyone uses a string equal to a URL that they effectively "own", such as your GitHub account (or actually own, such as your own domain), then these name collisions will not occur (excepting the fact that ownership of URLs may change over time).

It also makes it easier to go get your project, since the host location is part of the import string. Every source file that uses the package also tells you where to get it from. That is a nice property to have.

Where do I initialize git?

Your project should have some root folder that contains everything in the project, and nothing outside of the project. Initialize git in this directory. It's also common to initialize your Go module here, if it's a Go project.

You may be restricted on where to put the git root by where you're trying to host the code. For example, if hosting on GitHub, all of the code you push has to go inside a repository. This means that you can put your git root in a higher directory that contains all your repositories, but there's no way (that I know of) to actually push this to the remote. Remember that your local file system is not the same as the remote host's. You may have a local folder called github.com/myname/, but that doesn't mean that the remote end supports writing files to such a location.

If anyone help me understand whether my-branch will be matched with the remote one or not

Probably. But it's impossible to be certain from the info you have given. To find out, say

select() can set a timeout for the connection part.

Yes, but only if you put the socket into non-blocking mode before calling connect(), so that connect() exits immediately and then the code can use select() to wait for the socket to report when the connect operation has finished. But the code shown is not doing that.

setsockopt() with timeval can timeout the receiving portion of the code

Yes, though select() can also be used to timeout a read operation, as well. Simply call select() first, and then call recv() only if select() reports that the socket is readable (has pending data to read).

Try something like this:

You shouldn't necessarily have to implement a full custom atomic API, it should actually be safe to simply pull out a pointer to the underlying data from the atomic and pass it to the system.

Since std::atomic does not offer some equivalent of native_handle like other synchronization primitives offer, you're going to be stuck doing some implementation-specific hacks to try to get it to interface with the native API.

For the most part, it's reasonably safe to assume that first member of these types in implementations will be the same as the T type -- at least for integral values ^[1]. This is an assurance that will make it possible to extract out this value.

... and casting std::atomic to u/int* is UB

Setting display: flex turns the sizing of child elements over to the flex container. If you don't want the individual elements to resize, set flex-grow: 0, flex-shrink: 0, and flex-basis: 200px. You can do all three using the flex shorthand:

You can use simply intent.putExtra instead of worrying about which variant like put_____Extra to use.

Your problem is that you use async in a foreEach loop here:

The optional identifier ? is for the last thing, either a characters or group. So the expression ([a-z0-9]{1,3})_? makes the underscore optional, but not the preceding group. The solution is to move the underscore into the parenthesis.
