[Book Review] OpenStack Cloud Computing Cookbook

It’s another review of book from Packt Publishing. This time, I’ll tell you a review about a book of Cloud Computing. I haven’t finished reading this book yet, just read a few chapters. But my impression about this book is a bit disappointed. Actually, the topic of this book is very interesting. This book is all about building your own private cloud using a tool called OpenStack. If you have basic knowledge about Linux and VirtualBox, especially its command line, you won’t get troubled. Most content of this book are Linux shell command. Even there is GUI version of the command, this book only show the command line version. Read the rest of this entry »

In this post, I’d like to give you some review about a book which I just read. This book is about Object Relational Mapping (ORM) in PHP. As we’ve known, PHP is a favourite web programming language, and mostly, they work with a database too. Some programmers use PHP native database API (php-mysql, php-postgresql), another programmers use ADODB to simplify their works. But there is another way to manage your data in RDBMS, you can use Object Relational Mapping. This technique will map you data in your RDBMS into objects in programming language. Any changes made to the object will affect the related data in the RDBMS, and vice versa. Read the rest of this entry »

Did you have trouble when connecting your Linux to your network?  Did the network speed drop? Before you throw your computer, please check its log with dmesg. If dmesg shows repeated messages like eth0: link up and/or eth0: link down, then it must be your lan card driver problem. If you use Realtek LAN Card R8168, then it is the problem. Your Linux will load r8169 driver that have some bugs, instead of r8168. So, the solution of this problem is installing r8168 driver to your Linux, and disable r8169 module.

In Windows, you can set your wallpaper as a slideshow. So if you have many pictures and want to make all of them your wallpaper, you can do it with slideshow wallpaper. One of my friend said that Ubuntu already has it by default. But when i use Linux Mint, i can’t find it in wallpaper selection menu. So i search for how to use slideshow wallpaper in Linux Mint.

And then i found Desktop Drapes. It is a gnome-based application that can make auto-change wallpaper based on your pictures collection. Overall, it is a good application. But minimum interval for 1 wallpaper is only 5 minutes. In Windows you can have about 30 seconds interval.

To use it, you can install it from repositories with this command :

apt-get install drapes

Below is example screenshots of Drapes running in my computer.
