In upcoming Internet Explorer version (IE9), one can triple click text in a webpage to select a whole paragraph (vs double-clicking that already existed to select a whole word) of text.

I was delighted to see Windows Live Writer 2011 supports adding a WordPress blog nicely (pretty much automagically) and it even shows for each post a Tags input box at the bottom apart from the Categories option. It wasn’t showing a tags input box when working with Windows Live Spaces since it didn’t support such [...] Διαβάστε περισσότερα »...

After Microsoft recently killed blog statistics (even though primitive were better than anything since MS didn't allow scripting) on Live Spaces I was definitely going to move my blog elsewhere.

In fact http://www.google.com/test and http://www.google.com/test.html used to return different error page, but now it seems they've fixed this to return an error page of the same design. However still the Google logo colors are solid with not gradient as the more modern logo used at http://www.google.com Should have kept a screenshot I guess.

It's been a long time, since I posted something here, almost 3 months. Thing is that I had some long lasting vacations during August, I moved to a new company, even a new country. Trust me, no time for blogging. To catch up a little bit: I was awarded with the Windows Azure MVP title. I'm speaking at the keynote, along with some of the best it pros in Greece, of ITPro|DevConnections 2010, a huge technological event being held in Greece, 27th and 28th of November. It's almost sold out at the moment, more than 280 participants. I moved to Brussels for at least 6 months, for a project. I'll be at TechEd 2010 Berlin helping out Brian H. Prince on Windows Azure Hands-on-Labs/trainings etc. It will be nice to meet with some people there, come and find me! Lots of other stuff.. I'll catch up with blogging next week. There are a lot of stuff I want to write about. Be sure to check my blog every now and then, or subscribe to my RSS feed. Right after ITPro|DevConnections 2010 I'll post slides and code and trust me, it's...
