The fractal Google logo

Posted by Harry Seldon on January 14, 2010

Thx Pixgeeks for reminding me of this nice Google logo involving fractals.

fractal_google_logo

It was in memoriam to Gaston Julia’s Birthday.

In case I need to precise, the fractals you see on the logo are called Julia sets because the French mathematician Gaston Julia described them first. However, most of my readers already know that, right? ;-)

To say something only initiated people can understand: “The Mandelbrot set contains all Julia sets”. (That is why the fractal on the left is actually the Mandelbrot set.)

You can check all google logos here.

Need a Google Wave invite? Just add a (nice) comment

Posted by Harry Seldon on November 29, 2009

I have got 8 remaining invites for Google Wave. If you want one, just add a (nice) comment below with your email in the email field (not in the comment itself). I will invite you from Google Wave, asap. It will take a day or two before you receive an email from Google that will give you the actual access to Wave.

Once you are surfing the wave, remember, to search for public waves, use this query: with:public. To search for French public waves, use with:public tag:fr.

If you want to create a public wave:

  • Add public@a.gwave.com to your contact list (press enter even if it tells you the user does not exist)
  • Create a wave and add this contact.

Enjoy Wave.

Google Spams by paper mail

Posted by Harry Seldon on August 09, 2009

Is “Google spam” the new Google app?

I have just been surprised to receive a letter mail from Google Adwords asking me to use their service. That-is-to-say, to promote my website through the Google ads of other websites.

I understand that Google needs to promote their main cash cow. However, I do not understand that they send a paper mail and not an email. Even if there is a promotion code, it could well be sent by email.

Google has disappointed me. I thought they were more high tech and more ecofriendly than that. Moreover, I thought their cash cow was naturally working without needing much marketing even in non-US countries.

A good point for Google, however, is they sent their mail in French.

In case you wonder what this mail is about. Here is a summary translated from French. So it is not Google’s wording.

5 reasons to launch your marketing campaign through Adwords and gain customers with Google.

  • 1 You determine the broadcast zone of your ads (targeting by country, region, city)
  • 2 You define your budget and control your cost
  • 3 You pay only if an internet user clicks on your ad
  • 4 The configuration of your account is very easy
  • 5 A welcome offer : a 50€ credit to broadcast your ads

So dear Google, like many, I hate spams and I hate all the more paper mail spam. So please do not do that again. And btw, this mail reminds me to think about removing the Google ads thanks to which I earned in 3 months about 1.5€. That is I am close to be a millionaire ;-)

The mail is signed by Barbarin Martin, Head of Marketing, Google. I suspect, though, she is head of marketing for Google France. I am going to send her an email to be sure she reads this. I would have tolerated an email but not a paper mail. Moreover, I have just verified there is no option in my account to prevent this. That would be a good idea to add this option just like in general there are options to desactivate marketing emails in good websites.

PS If you think about this mail, it is an ad for ads. We live in such a crazy world.
