Every developer needs access to some servers for example to check the application logs. Usually, this is done using public-private key encryption where each developer generates their own public-private key pair. The public keys of each developer are added to the authorized_keys file on each server they should have access to. Painful manual changes So far so good. However, what happens when one developer leaves the company? In that case, the public keys of that developer should be removed from all servers.
As a developer you gotta love Vim! It is easily available on almost any server you login to. Most of the times, it will already be installed. You can customize it to your needs, but you should be comfortable with its basic functionalities as you don’t want to tweak it on every server. I thus like to customize it a little bit, but try to stick close to the default. But the best thing about Vim is that after some time learning it, it is so much faster and easier to edit text than any other editor.
So, we all regularly create backups of important data, right? Right. Well, at least I hope you do. For your personal data as well as any company data you are dealing with. It is fairly easy and straightforward to create e.g. a MySQL backup on a server, zip it up and always keep the last 10 days as copies. However, what happens in case your whole server’s disks have an unrecoverable crash?
