Two days ago, I was playing with DNSStuff (http://dnsstuff.com), doing some checks on my domain “0x82”. One of the tests was about some SPF thing that I never heard about.

It told me someone could send an email from anywhere, and make it appear that it was send from my domain, making it legitimate (ok, I know that this doesn’t make my email secure by himself). It told me that the solution was a SPF thing.

I’ve started reading about it, and realized that, although it seems a big hack (what? using the TXT field of a domain to store data??), it could help and protect your email. For that I needed to change the TXT record of my domain (try dig TXT 0x82.com on your console).

Then, to make sure that the email I receive is tested against this specification, I had to configure my postfix SMTP server. If you search on google for “postfix spf debian” you will find nice tutorials on how to implement that. It was really simple!

This week, log, the company where I will start working on Monday, celebrated his 6th anniversary. It is marvelous to see a company that relies on open source technology growing this fast.

So, congratulations log! I and hope I can contribute for the your continuous success during the next year :-)

Yesterday, after a long day hearing at the FIA World Motor Sport Council (WMSC) in Paris, Vodafone Mclaren Mercedes F1 Team have been excluded from the 2007 constructors’ championship and fined US$100 million for cheating and using Ferrari F2007 information on their 2007 car (source).

That could explain why they suck in the last years and suddenly have a very fast car :) Good news for Ferrari, that have just assured the Championship Constructors’ title.

Yesterday I started watching a new series called It’s Always Sunny in Philadelphia. FX Productions started sponsoring diggnation advertising this show, and I decided to watch the pilot.

So far so good! I’m at the 4th episode and I love it. It reminds me of my University friends, and the 20 minutes format is excellent. I think you should really give it a try.

I am back online. My transition is almost finished, I still have to solve one or two little things.

I hope I can have new stories to blog about from now on :)
