About PostgreSQL

PostgreSQL is an object-relational database management system (ORDBMS). It is released under a BSD-style license and is thus free software. As with many other open-source programs, PostgreSQL is not controlled by any single company, but relies on a global community of developers and companies to develop it.

Not Knowing the Direction of Qiblah

Question :

Respected Scholars, As-salamu `alaykum. I would like to ask you a question which has been on my mind for very long. I was outside and the time for Prayer came, but the place had no mosque or place to pray. I didn’t have a compass at the time due to forgetfulness. I can tell the direction of the sun but on that day the sky was not clear and I couldn’t see the sun. So I prayed in a car park facing a pillar as the sutrah. Is my Prayer valid? Should I repeat it? Please provide me with an answer.

Sudoers in Ubuntu

By default, root acount in ubuntu is locked. This means that you cannot login as root directly or use the su command to become the root user, however, since the root account physically exists it is still possible to run programs with root-level privileges. This is where sudo comes in; it allows authorized users (normally "Administrative" users) to run certain programs as root without having to know the root password.
