-  A Beginner’s Guide to NoSQL by Sufyan bin Uzayr

Let’s say you’ve decided to set up a website or an application. You’ll obviously need something to manage the data. Yes, that’s right, a database. So, what is it going to be?

Introducing MariaDB 10.0 by Daniel Bartholomew

The MariaDB Project is breaking with MySQL’s version numbering for their next major version. Previous versions of MariaDB either matched MySQL’s version numbering (5.1, 5.5), or slipped in between (5.2, 5.3). MariaDB 10.0 ends this practice. Currently in development, MariaDB 10.0 offers better performance, more features, and maintains compatibility with MySQL – with some caveats.

Understanding Linux Filesystem for Better Storage Management by Mulyadi  Santosa

If you had a large warehouse, how would you organize it? Would you want everything inside it to be scattered around? Or would you have an arrangement pattern in mind? If so, what kind of arrangement pattern? Would you group things based on size or similar? Of course, the way a room is organized will determine the room’s first and final impression to clients or customers for example. The benefit to having an organized space is that it becomes much easier to locate items.
