In a previous post, installing Kivy on Ubuntu 15.04 was issued. Today, there is a main development which is using SDL2 instead of Pygame. You can find why this is significant on Google.
I cannot find Kivy and Buildozer installion document for Fedora 22 and decided to write a recipe for it. So, lets get started. You will find 8 main sections for this topic:

In the previous post, how to install Kivy and Buildozer on Ubuntu is examined. In this post, you will find stages making APK files on Ubuntu with Python and Kivy using Buildozer. If you have followed the previous tutorial, you have already installed Buildozer on your virtual environment; however, it is not ready to making APK files for now. To test this statement, create a folder with a very basic main.py file(example from Kivy.org mainpage): Continue reading [HowTo] [Python/Kivy] Building APK With Buildozer

Raspberry Pi 1 için hazırlamaya başladığım ancak devamı gelmeyen bir yazı vardı. Elime +Onur Kasemlar‘ın Raspberry Pi 2’si deneme ve kurulum için geçince, kurulum için kullandığım yöntemi de anlatmaya karar verdim.
Raspberry Pi ile ilk deneyiminiz olacağı varsayımıyla gidersek, şöyle bir kutudan:
Şu kartı çıkararak başlayabiliriz: Continue reading Raspberry Pi 2 Kurulumu & İlk Kullanım ve Kablosuz Bağlantı Ayarları
In Linux, there may exist a need to prepare a screencast to tell something to somebody or make a screencast for public, etc. To make this, there are several alternatives. I have tried a couple of them and RecordMyDesktop have become my favourite.
To install it, just write in console:
sudo apt-get install gtk-recordmydesktop
If you have trouble with terminal screens, you can make a search in Software Center and install it, but I hardly suggest that you get accustomed with the console. Most of Linux distribitions I have met have this application in their repos, so you can utilize it without adding repos.
When the application is installed, you can run it from terminal by typing gtk-recordmydesktop or can make a search in menu by typing the same keyword. The application has a graphical user interface which is very easy to deal with. I prefer to make some practices to prevent voice or image problems.
At the end, I want to warn you that there is a problem with recording web surfing. The video is getting confused at the end. I will make some tries to record correctly, afterwards edit this entry.
