Reinvent the wheel and make it Elon Musk...

Solarcity aims to lower the cost of solar panels in order to make them more attractive to customers in the US. In the end, it is a matter of make it more appealing to individuals; better colors, lower (maybe) prices and financing: use now, pay later. One of the main concerns regarding solar panels is their efficiency. Efficiency means how much power you can get from surface area. Wikipedia provided this amazing plot on the efficiency of different technologies over time. It is interesting to realize what are the companies involved in the developments of each technology....

This blog now is encrypted

This blog now is encrypted

One of the problems that has been concerning me for the last few months is the privacy online. I’ve already written about how to encrypt a hard drive, or discussed about the unsafety of passwords. Now it is finally time to make an improvement to the blog’s privacy. Starting from now, you may notice that the default way of accessing this website is via https, meaning that all the communication between you and the server is encrypted. I was thinking in implementing secure HTTP, but I didn’t want to add an extra fixed cost. Recently, Dreamhost (my host...

I am interested in what traces we leave in landscapes, in cities and places. But I wait until...

Passwords are from last millennium, but ...

In our current lives the first line of protection against identity theft, money loss, bank fraud, privacy vulnerabilities and a long etcetera is a password. In principle to be secure a password needs to be something only you know; if you think hard enough you’ll realize that the sentence doesn’t make sense. If it is something only YOU know, how are you going to access your e-mail account? How can Google know that your password is right if they don’t even know what is it? This is a really big issue: a password is something at least two people know, to...

Is there science behind the VW scam?

The first time I’ve read about the VolksWagen strategy to bypass emission controls in the US it was from the perspective of business responsibility. People started to wonder how deep into the company is this scamming moral entangled. I honestly don’t care about this, since I always assume huge corporations have no such things as moral, regardless of were they are based. I was however really surprised and interested by the chosen strategy. In my mind, if I ever develop a product that doesn’t fulfill the regulations I would try just to bribe the people...
