GDG Devfest Barcelona 2013 Roundup

GDG Devfest Barcelona 2013

First I need to say the GDG Defvest Barcelona 2013 was a great event, with really great speakers and amazing technologies.

I think it is best if I go one by one on the conferences I assisted.

Customer Development with Google Tools

It was a nice talk oriented to new startups. They showed a nice use of Google technologies to be able to achieve a product – market fit. There was a tool for every step along the lean methodology. Among the different free or relatively inexpensive tools available from Google, they showed us a good way to use trends or customer Survey for the discovery part to research the market and to use Google Analytics and Google AdWords for market validations. Essentially max out the power of the tools Google has made available for start ups.

All in all it was a good talk: it gave a hands-on point of view about one of the best ways to create and develop a product-market fit, how there was a specific tool to advance in each area and some of the traps you can find along the way. A good way to start the GDG Defvest Barcelona 2013.


Liquid Galaxy

I was really amazed by this technology. I didn’t know anything about this before coming so first I had no expectations and second it was a positive surprise. Liquid galaxy creates an immersive sensation by using Google maps and Google earth among multiple huge displays. We were able to see the technology that was behind such great product and also some of the multiple possible applications of this technology.… Read the rest of “GDG Devfest Barcelona 2013 Roundup”


GDG Devfest Barcelona 2013

GDG Devfest Barcelona 2013

Tomorrow October 11th is the GDG ( Google Developers Group) Devfest Barcelona 2013, the biggest event for developers dedicated to Google technologies in Spain. It takes place at the UPC, the Polytechnic University Of Barcelona and also at the  the Mobile World Centre, the central building of the Mobile World Capital.


The event will bring together more than 600 expert developers interested in Google technologies. The ticket assistance count is actually around 900 people.


It will be a Full Day event with a lot of appealing conferences and seminars. Topics are very interesting and they cover a wide range of themes, from Startup and entrepreneurial oriented talks to a Google Glass hands on.


I am particularly interested in the conference about Customer Development with Google tools by a Google Developer program manager in Madrid, the Google Glass hands on and an entrepreneurial seminar about starting a company at San Francisco and Barcelona.


I was looking forward to get an entrance that included the evening event at the Mobile world center, where there will be a conference about App marketing and media communications, but unfortunately I was only able to get a day pass (not bad at all though ;-) )


If you want more information about the event, you can access the GDG Barcelona website. I hope I see some familiar faces tomorrow at the event.


Moral behaviour and inequality

moral and unequal pay

We tend to think that the sense of morality and equality are only human traits. However, Psychology has proven that this trait is shared among many different animal species.


It is of particular interest the work of Frans de Wall a biologist and primatologist known for his work on the behavior and social intelligence of primates. We can see in his experiments that monkeys among other animals share a sense of morality. 


For instance, if two monkeys execute the same task and are rewarded unequally, then the monkey who was rewarded poorly will complain and even protest. It is something better seen than explained so I would like to share one of Frans de Wall‘s conferences in TED that illustrates what I’m talking about here.


Here is the short version (for people with less time or who just want a quick peek at the experiment)



The two monkeys are rewarded with pieces of cucumber (the poor reward) and grapes (the better reward).


I think that moral behavior is based upon a sense of fairness / reciprocity and empathy / compassion. What I like about this experiment is that it allows to focus only on the fairness and reciprocity component of moral behaviour because the way they reward the monkeys is not something that they can share.


Of course, humans may react differently in case of inequality because we have “deeper and more complex” reactions, or rationalized reactions.… Read the rest of “Moral behaviour and inequality”


What motivates us


I would like to share a video that from my point of view should be a classic about what motivates us.

It’s an adaptation of Dan Pink’s talk at the RSA.



It is related to Maslow’s hierarchy of needs, focusing on the top of the pyramid where the classical reward system is not as effective as it would seem.


I think one of the biggest truths it speaks is that contrary to popular beliefs, rewards can be a double edge sword. They can sky rocket productivity in repeatable tasks but can also decrease creativity and productivity in mind challenging tasks.


Of course, this does not mean that people should not reward intellectuals, but that different kinds of needs require different kinds of incentives: there is no “one-size-fits-all” solution.


About Software Engineering

Barcelona Ruby Conference

I’d like to share one of the best conferences I’ve seen on Software Engineering.

It’s a talk from Barcelona Ruby Conference 2012, featuring Paolo Perrotta, author of “Metaprogramming Ruby”.



This conference really offers another point of view about the whole programming, technology and engineering industry with a nice historical and social side. It’s surprising how he analyzes big mistakes in the computer industry and explains them as conceptual mistakes from a human point of view. Worth seen 100% for tech people!
