After a short period of 380 days I am back blogging. It just happens I bought a wonderful device called iPhone four says ago and I just found out about an application for it called WordPress and this post and many future posts will be written on my iPhone.

If you use the ftp-client in Terminal frequently, then it is probably to log in to the same server, entering the same username and the same password.
There has got to be a more clever way to log-in every time. Here is how – however, have in mind, it involves having the username and password in a plain text file in your home directory, although it is hidden. We will modify the rights so only the logged-in user can read and modify the file. Continue reading »
