Because of HTML5’s momentum, it is now a technology that every XML developer has to deal with. Fortunately HTML5 supports a proper XML serialization. Learn about the XML form of HTML5 including some key differences from older XHTML conventions and learn how to practically apply this vocabulary in modern web browsers.
First post
This is the first post in this blog, to get things going. I will try to post as often as i can. I mainly post at my external blog but i will try to post the same things here so that linux.com users can follow my writings here instead of at my blog.
I am a Debian user and a C developer. I am using software like VIM/GVIM, Subversion, Geany, Anjuta, and others to do my work etc. This is what i will blog about when i have the time.
Favorite subjects would be C, NCurses, GTK+, Subversion, administration of Linux systems (Debian) and a few other things. I am also a science geek which i write about in my external blog. This i wont blog about here but i mention it because it will take a lot of my time and it will make it difficult for me to post reguarly about linux and programming.
I have been using Linux since 1997…

U.K. Officials Suggest To Use Linux

U.K. Officials Suggest to dump all the Microsoft software and start using Linux and Open Office. The Linux and GNU software offer a free or a very low cost alternatives to Microsoft software, so why to expend on a system which is expensive if you can have it free or at low cost. In words of Prime Minister David Cameron:
In terms of spending less, what about migrating the whole of government (the NHS, education etc.) from Microsoft products to Linux and open-source software like Openoffice.

App Inventor for Android

Google launch the App Inventor, a framework to develop apps for Android. You can create any app is in your mind.
You can build just about any app you can imagine with App Inventor. Often people begin by building games like WhackAMole or games that let you draw funny pictures on your friend’s faces. You can even make use of the phone’s sensors to move a ball through a maze based on tilting the phone.
But app building is not limited to simple games. You can also build apps that inform and educate. You can create a quiz app to help you and your classmates study for a test. With Android’s text-to-speech capabilities, you can even have the phone ask the questions aloud.
The App Inventor interface is very simple but powerful. The Google developers make “almost everything” to help you with the development (touch controls, buttons, etc).

If you like it, or you always dream to make your own android app, so you can. Just fill this form and you are on your way to start making Android Apps with the Google App Inventor.

Spotify for Linux

Spotify is an on-line music player with thousands of songs, music, etc. This program was available for Windows and Mac (and you can run it with wine) but now you can use it on your Linux system.
A lot of our developers are using Linux, obviously they want to listen to music while they’re coding away and looking at the feedback we get it appears that they’re not the only ones. So today we’re pretty happy to present a preview version of Spotify for Linux.
Built by our brilliant developers during hack days and late nights, it shares most of the same features as our Windows and Mac OS X desktop applications. Unfortunately, there are issues regarding decoding of local music on the Linux platform so we haven’t included support for local files in this version.

Opinion: Is Google Chrome Really the Windows Killer, or the Linux Killer?
Since late 2009, talk of how Google’s Chrome OS is being positioned to “take on” Microsoft Windows has been promoted by individuals who I believe have no idea what they’re talking about.
Google Demos Codeless Android Development Tool for Students
Google has announced a new browser-based visual development tool called App Inventor that allows users to create Android applications without having to write any code. It appears to be aimed primarily at students.
App Inventor enables user interface design with a simple drag-and-drop layout system. The behavior of the user interface elements can be programmed via a visual development system…
New Wiki, What Now?
We just switched to the new wiki. So here it is. And now? Let me explain what you can do to help!
Create your user page
Every user of the wiki has a personal page and we did not transfer any of them. We wanted to use this opportunity to brush them up and standardize them. Your userpage should be your first task in the new wiki. If your username is Geeko, just go to http://en.opensuse.org/User:Geeko and press “create”. After that load the userpage teamplate by pressing on the “Load” button. Then fill out the form and you will get a nice standardized userpage!
You can also of course transfer your old userpage. Just go to http://old-en.opensuse.org/User:Geeko to find the content.
Report Missing Pages
Can’t find your page? Think we missed something? Just report the page to the opensuse wiki team! We will try our best to help you getting it back!
Transfer Missing Pages
Want to get your hands dirty? Dive right into the new wiki and learn how it works on the Wiki Portal or the previous posts on this blog. After you did that and know all the new wiki Kung-fu you go and find the pages you think are missing on http://old-en.opensuse.org. Now you have two options, either use the Special:Export page on the old wiki and the Special:Import on the new wiki if you want to transfer the article with all of its history or you just copy and paste the article if the history is not that important.

Spotify Streaming Music Player Comes to Linux
Linux: Spotify, our favorite not-officially-available-in-the-U.S. music player, has just released a version of their desktop player for Linux users.
Spotify for Linux is still a work in progress, and it’s currently lacking support for local file caching due to decoding problems (meaning everything is streamed rather than stored locally), but it’s great news for Linux users who want to…
