How To Set Up A Web-Based Enterprise Password Manager Protected By Two-Factor Authentication
While it is great that more services such as Facebook and Google are offering two-factor authentication, there are still plenty of services that do not. What is the next best thing? Using a password manager and incredibly complex passwords. A password manager allows you to use different passwords at all the sites and services you visit, but it creates a 'keys-to-the-kingdom' problem. This tutorial will show you how to install the WebKeePass open-source web-based, enterprise password manager and how to protect it with two-factor authentication from WiKID Systems. Note that we have not evaluated the security of WebKeePass - this would certainly be worthwhile. Our primary selection criteria were: open-source, multi-user and allowed for external authentication, in this case via LDAP. Another option that looked promising was CorporateVault.

Using Google Translate From The Command Line
I have found an article in one of the most famous Linux Arabic forums, it describes how to use Google Translate from the command line. It is a good script but it is needed to write the language pairs every time and I used to make the computers work for me not to work for computers, so I didn't like to do that write every time I want to use the script, usually I translate from English to Arabic, sometimes from Arabic to English and fewer times form some other languages to Arabic or to English if I found the direct translation from that language to Arabic is not clear enough. I have edited the script so now it checks the command arguments number.
