It is not new that many people are searching for the not very new codec G.729. Since this year (please google it), the codec G.729 is not under patent, therefore you can use it without paying patent fees. This is a huge step for the VoIP work, why? Because the G.729 codec offers many advantages, one of them is the low bandwidth requirement; it needs about 11 kbps up and down each. If you think it, the less bandwidth required, it means your service will be more tolerant to the overuse of links. It is very common that in an office or a residence, more than one is watching any kind of streaming or downloading a big file.

Because of this, I think it is very important to tell the world how to install G.729 on your FreeSWITCH server.

Today I have published in OKay's RPM repository RPMs for MariaDB 10.2 repository. MariaDB is one of the most popular database servers in the world. It’s made by the original developers of MySQL and guaranteed to stay open source. Notable users include Wikipedia, Facebook and Google.

MariaDB turns data into structured information in a wide array of applications, ranging from banking to websites. It is an enhanced, drop-in replacement for MySQL. MariaDB is used because it is fast, scalable and robust, with a rich ecosystem of storage engines, plugins and many other tools make it very versatile for a wide variety of use cases.

MariaDB is developed as open source software and as a relational database, it provides an SQL interface for accessing data. The latest versions of MariaDB also include GIS and JSON features.

According to the MariaDB Knowledge Base, upgrading from MariaDB 10.1 to 10.2 is quite simple. Please read the article before any change.

RPM's are available for Centos 6 and 7. And you can find it if you type yum search mariadb102-release.

If you have studied any engineering career, you should have studied at some point numeric analysis and learned the least-squares method. Just remembering you, least-squares method aims to minimize the error of the given points when guessing the curve coefficients.

So, if you have some points and you know the order of the equation, this is what you need to know to get the coefficients.

I will write in this article how I used a PHP Artifical Intelligence library to solve any N-order linear equation.
