Localization, internationalization and the Finnish language

Open source might make you think about geeks who mostly talk to computers with programming languages. Actually human language skills are just as important. Translators are needed in every international open source project. Localization becomes a necessary task in almost every open source project in Finland.

Free Your Android phone (and upgrade to the latest Android version)!

Most Android phone manufacturers provide operating system upgrades, so you can run the latest version of Android even with an older smart phone.

However not all Android phone manufacturers provide upgrades, or […]

Free manuals for open source software

The fastest web server in the world?

Speed matters. Over and over research shows that when the speed of a website increases, the activity of users increase. Even if the changes are small, like a half second, and users are perhaps not conscious about it, users will view the overall experience as better. Besides website popularity, high-speed websites are also capable of handling more […]
