Friday the 13th, a bad-luck message JS/redir.BS for a wordpress website

By
JS/redir.BS is a malaware that silently is stored in your website and will cause something ugly to happen: lose access to it.

There is no simple way to know when it got there, but several places can give you a clue on how to get rid of it. Important advice: take care of your website security, create backups and change passwords every now and then! Wordpress is a strong tool, but not invensible.

As I know how to control my computer and get rid of malaware, I decided to create a simluation in my computer, that was risky, but the fastest way to do it instead of waiting for the hosting company to help me.
I did a clean installation of Wordpress last version, the one I use in my website.
As I was suspicious of the theme, that was the first thing I copied from the server to my laptop. When I tried to move the theme folder to my local Wordpress installation, there it was. My Antivirus poped-up and blocked the virus, luckily it was just in the header file.
If you still can access to wp-admin on your website, go to the infected file, and get rid of it or of the infected code. It is Javascript code.
Change your passwords, all of them. Do the same for the keys using the Wordpress generator and overwrite them at the wp-config file.

If your case was not that simple:
First, confirm if your website is infected with malaware: http://sitecheck.sucuri.net/scanner/
Second, make some good reading http://codex.wordpress.org/FAQ_My_site_was_hacked
And learn how to Completely clean your hacked wordpress: http://smackdown.blogsblogsblogs.com/2008/06/24/how-to-completely-clean-your-hacked-wordpress-installation/

Either way, make sure your website is not infected http://sitecheck.sucuri.net/scanner/

Home buying process, the real deal

By
One day you wake up and think "I'm gonna buy a house" And keep reasoning "it is time to use all the time and effort and savings in something more durable, a real investment". That one day for me meant almost two years of digging, reading, researching, saving and most importantly building my credit. Here's a summary of what I learned when I made a first try... Workshop - you'll need this in the future, make sure is HUD approved. It is a workshop that explains what you're about to start. I recommend this. It took me a few months, because I dedicated 8 minutes some days....I think it's intended to take you 8 hours. eHome America was the provider I chose, and I got a voucher for the free workshop from a non-profit that provides resources for new buyers. Counseling - After you complete the workshop, bring your certificate of completion and meet with a counselor. I chose to go to the same agency that gave me the voucher, because they already knew...

Technology and where are we going?

By
During this RSA presentation (starts on 11:00), lecturers make an analysis on where technology is transforming our society.  Some remarkable affirmations: "We decided to put all our information into a big grey box, and hope nobody is looking in." "Every single human being here has access to the internet" "Technology improves individual capacity more than social" "Teach people not answers, but how to ask questions" "We can't leave people off the hook" "Data, information and knowledge are different levels. We should slow down to learn/teach how to make questions" Despite all this progress we still have a lot of things to do, such as, improving security.  And also to reshape our mentality and our culture of sharing. We also should include and consider each and every individual to get the benefits of technology. As they mention during the QA, there has to be areas where designers and users can com...
