You want to push a new project to github, but it asks for your username and password each time.
First, check the remote repository:
git remote -v
which will respond something like
origin https://firstname.lastname@example.org/yourname/yourrepo.git (fetch) origin https://email@example.com/yourname/yourrepo.git (push)
Execute the following command:
git remote set-url origin firstname.lastname@example.org:yourname/yourrepo.git
Notice that you need to do some transformations: “
https://yourname@” is replaced with “
git@“, and “
/yourname” becomes “
Now “git push” should work fine.

At my workplace I got a new monitor (27″) that came with an HDMI cable. I connected the monitor and the PC but the monitor displayed a “No signal” error. I tried it with a VGA cable and it worked fine but the screen was not sharp enough. I had the impression that the lower quality was caused by the VGA cable. Hmm, how to make that HDMI connection work?
The solution is trivial. You need to select HDMI connection in the settings of your monitor, in the menu :) Really, that’s all. And the difference is clearly visible. Now my screen is sharp, much better than the VGA. So if you have HDMI connection, use it.
