Since some hours is the default KEX in OpenSSH! Several weeks ago Aris added a new Elliptic Curve algorithm for key exchange using Curve25519. After he wrote some kind of a RFC and implemented it in libssh he started to suggest a patch for OpenSSH which finally has been integrated.

Writing and reading code

You’ve probably heard that a developer of an established software project writes an average of 100 lines of code (loc) a day. I can say that this applies to me. So if you write 100 loc per day, how many do you read? I would estimate that the amount of time you spend on reading and understanding code is significantly more than on writing code....

vim modelines in git config

I’m working on different Open Source projects and most of them have different coding style guidelines. Mostly spaces or tabs or different tabwidth. The easiest thing would be to store these information in the git config of the project. So here is a easy and secure way to have modelines in the git config. So first I set the modelines (here for the Samba project):...
