It’s time to blame the social medi...

I have been listening a lot to people saying that the results of the US election some days ago has to be blamed to social networks, or as now is fashionable to call them social media. Mainly the point is that normally we have friends on Facebook with whom we share political thoughts. Therefore the news they post online are the ones that represent our own opinions and we loose the full spectrum there is around. Therefore we are just reinforcing what we already think and we will miss the point. In this way we will not get in contact with other realities, we think Clinton is...

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....

Colors optimized for color-blind people

Colors optimized for color-blind people

Color blindness is a vision disorder in which individuals lack one or more color receptors. It affects approximately 8% of males of European descent and 0.5% women. It means that in an audience of 16 people, half men half women, chances of having at least one color-blind person are of 50%. Of course when you consider the audience of a written piece of work this number may grow quite substantially. Therefore it is important to have a color palette that is suitable for color-blind people. The image below was made based on the recommendations that appeared in Nature Methods...

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...

Musical Saturday: Alt-J – Taro

Musical Saturday: Alt-J – Taro

What a lovely musical discovery Alt-J. An English “Geek Rock” band. The song I’m bringing today is Taro, based in the love story of two war photographers who died doing what they loved the most and their reunion afterwards. I’m copying the lyrics after the video. More of Alt-J on Spotify Indochina, Capa jumps Jeep, two feet creep up the road To photo, to record meat lumps and war, They advance as does his chance – very yellow white flash. A violent wrench grips mass, rips light, tears limbs like rags, Burst so high finally Capa lands, Mine is a...

I’ve found recently in The Economist an interview to the german film director Wim Wenders, who has an ongoing photo exhibition in Berlin. Wenders is known for some movies like Buena Vista Social Club, Pina, Der Himmel über Berlin (Wings of desire) but his photographic skills are lesser known. In the interview I’m sharing just below, there is a sentence I’ve liked: I am not a landscape photographer. I am interested in people. I am interested in our civilization. I am interested in what traces we leave in landscapes, in cities and places. But I wait until...

Passwords are from last millennium, but millennials don’t care

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...
