Want to see a Nobel laureate saying I did a mistake?

If you have read Kahneman’s “Thinking Fast and Slow” you should be interested in reading this blog post: Reconstruction of a Train Wreck: How Priming Research Went off the Rails...

And, even more interesting, Kahneman’s response to it.

It is not that often to read a Nobel laureate something like "This was simply an error: I knew all I needed to know to moderate my enthusiasm for the surprising and elegant findings that I cited, but I did not think it through."

Hats off!!

What does it mean to love someone?

To love is "to be generous in the interpretation of the behavior of another person"
Alain the Botton in this video

The video below is a better version of the same talk. I found it very interesting.


I also recommend the novel he mentions in the video, The Course of Love.

Finally I recommend his YouTube channel, The School of Life full of thought provoking videos.

Oops!...I Did It Again. CausalImpact

I don't consider myself a geek.

But then I found myself studying, understanding, admiring, playing and having a great time with CausalImpact, a R package for estimating causal effects in time series I end up questioning myself.


Is there any hope for me doctor?

edit 18/Apr/2017
I found this video where Kay Brodersen explains the package

What do you need to be to succeed on YouTube?


"... and the fact that XXX is not simply a vlogger. Yes, XXX is a personality; yes, XXX is an incredible community builder. But in fact XXX is an entertainer. XXX is an actress, she's a comedian, she's a rapper, she's a writer and even more than that she's a producer and a programer. And she thinks extremely strategically about how she programs her content for her audience."

Heard today to introduce one of the biggest youtubers. In my opinion spot on describing what do you need to be to succeed on YouTube.

Three Priceonomics posts that I covered months before them


I'm a big fan of Priceonomics. I enjoy their content so much that I think have read every single post they have published.

So you would understand that I feel honoured finding out that every now and them Priceonomics publishes a post about a topic I have touched a few months before. Find below the three examples I have tracked so far.
Once is chance, twice is coincidence, third time is a pattern. No pressure on future posts Javier!

Mi consejo a un taxista

Taxista, vende tu licencia.

En serio, considera seriamente la posibilidad de deshacerte de tu licencia de taxi cuanto antes.

Tu licencia te ha costado muchos miles de euros y, créeme, su valor está amenazado. Si no la vendes corres un riesgo considerablemente alto de que en el futuro no valga nada.

Tu problema no es Uber sino las cientos de empresas que usando una tecnología cada vez más accesible pueden permitir a cualquiera mejorar el servicio del taxi de multiples formas. Pueden hacerlo más barato, más conveniente, más personalizado; mejor en definitiva.

Tus protestas y bloqueos no sólo no te ayudan sino que contribuyen a publicitar a estas empresas y hacerlas cada vez más conocidas.
Las protestas de los taxistas catapultan la aplicación de Uber al número 1 en la Apple store (fuente)

Echa un vistazo al tweetline de Neelie Kroes, la vicepresidenta de la comisión europea que lidera la agenda digital, y entenderás que los políticos tampoco van a solucionar tus problemas.

Respecto a las protestas de los taxis - la tecnología está cambiando muchos sectores. Los taxis no están exentos. Necesitamos trabajar con la tecnología no contra ella, no es el enemigo. 
Y los políticos no van a solucionar tus problemas porque nadie está interesado en defender el número limitado de licencias de taxi en una ciudad. Por eso mi consejo es que vendas tu licencia de taxi.

No hoy, posiblemente no mañana, pero empieza a dar los pasos que te lleven a la posibilidad de vender tu licencia cuanto antes.

A cuidarse

The right way to share a YouTube video in social networks...

... is to share a link to the video within a playlist.

Why is that? Very easy.

This is a screenshot that shows how this video looks like in watch page if I share its link http://www.youtube.com/watch?v=AEsYbfhAjg4
The videos in the red circle are other videos from my YouTube channel

Now, have a look at the same video shared within a playlist. The link would
be http://www.youtube.com/watch?v=AEsYbfhAjg4&list=PL6033DD2A09BAB4C5
The videos in the red circle are the same videos from my channel as in the previous screenshot. The difference is that they now have switched their place with the display ad, making those videos more likely to be noticed by the user and therefore more likely to be played.

This is very important because if a user is watching your video and then jumps to another video from your channel at least two positive things are happening.

The first one is your videos are getting your watch time (the metric that probably matters the most in YouTube). The second one is YouTube learns that after watching video A users are watching video B, both videos from your channel; and that will make more likely that whenever a users watches video A YouTube suggests video B as what to watch next to that user.

So, whenever you share a video, make sure you share the link to that video in one of your playlists.
