Here’s what’s inside:


-  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? MySQL, MS-SQL, Oracle or PostgreSQL? After all, nothing can be as amazing as a good old RDBMS that employs SQL to manage the data.

- 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.

- Step-by-step Integration with REST Payment Gateway Using PHP and MySQL by Dawid Ostapiuk

In our daily work we meet with problems of payment gateway integration all the time. If you are doing it for the first time, you can really encounter some problems hard to resolve. Mistakes made at the beginning always cost more in the future so we will give you some tips to avoid such problems.


Large UPs Systems for Data Centers by Dennis P. DeCoster-Large

Every large data center built today has some kind of uninterrupted or continuous power system incorporated within the design. Often running over a megawatt per single module capacity, these  UPS  or  CPS  systems  are  available  today  in  a  wide  array  of  options.   Indoor/outdoor, battery/flywheel,  parallel  redundant/distributed  redundant,  low  voltage/medium  voltage, transformerless or transformed, centralized or distributed, DC/aC, the list goes on. In this article, we will touch on a few of the more significant changes affecting the industry in 2011.

- Migrating and Managing Data Centers by Rich Casselbery

Most people don’t need to build data centers. More commonly, organizations either move into existing locations, or move to a colocation center that provides everything. If you do find your organization needing to build your own, it’s an experience. I recommend getting a consultant who can help with the process.

- 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.


Immutability in Life by Damian Czernous

Making an object immutable is always a good choice. Objects are used in many ways, but immutable objects have limitations. Let’s focus on value beans and find reasonable compromise for them.

- SeLinux Applied to Data Security by Lucas do Amaral Saboya

Security-Enhanced Linux (aka SELinux) was developed by RedHat, based on a National  Security  Agency  (aka  NSA) solution called Flask, they call it a “Result of several previous research projects in the area. SELinux consists on a flexible architecture called Madatory Access Control (aka MAC), this policy covers all processes running on the machine,  as  in  if  they  have  privileges  to  do such task or not. See a flowchart of MAC’s way of doing things.

- Display and Wrappers in MVP by Damian Czernous

MVP is an old concept for building modern Web applications. Using it we may gain modular, testable, and responsibility focused solutions; although it’s easy to break it during implementation. A display interface and class wrappers may help developers to keep on track.


- Introduction to MySQL Programming with Qt 5 by Leon Anavi

Qt is a cross-platform development framework that is widely used for application development for desktop, mobile and embedded platforms. Qt uses standard C++ but other programming languages such as Python, Perl, PHP and Java are also supported by language bindings. Learn how to connect to a MySQL database and execute SQL statements using Qt.
