Después de pasar las emociones del primer juego contra Grecia y estar en Brasilia, un poco más tranquilo de haber alejado los fantasmas de las pasadas fases de grupos.

Espero mañana volver a salir con la misma alegría del partido anterior más la alegría de estar en octavos =)

Después de 16 años y haber visto la ultima vez a Colombia jugar en Francia con casi 10 años, hoy siento una mezcla de alegría y tristeza, es una sensación que no se como describir creo que es como volver a casa después de mucho tiempo, o comer esa comida de casa que no sea probado por muchos años.

Por más increíble que parezca, uno se puede quedar encerrado en un aeropuerto porque una aerolínea crea que este itinerario tiene lógica y más sabiendo que yo no compre el tiquete por trayectos sino un viaje a Brasil, lo más increíble es que no veo como se le puede pasar a una persona o un software un error de ese estilo.

Además justamente ayer me llego el trip reminder 'bueno'.

Today I finished my update to Mavericks and for some reason emacsclient was saying that it can’t find a socket.

After rechecking and restarting my emacs server it kept saying the same, so for a couple of seconds I thought that my compiled version of emacs decided (https://github.com/sarcilav/dotemacs) to stop working, because when I tried to use the default emacs version of OS X, emacsclient worked again, so it was clear that something had changed and it was my emacsclient version, because for some reason after the update, it removed my symbolic link to the emacsclient-v24 and put its very own version of emacsclient-v22.

I've been studying clojure, and this is my first project/lib https://github.com/sarcilav/authy-clojure

Here is the entry at clojars https://clojars.org/authy-clojure

Sometimes you will need to generate assets with round corners.

For example for mobile devices or so, to serve from an api or whenever you can't use css.

For these cases you can use https://github.com/sarcilav/magick_round_corners

It is easy to use. Just look:

Today I was trying to use postgis adapter on a rails project but I got the following when tried to create a new DB with postgis

PG::Error: ERROR: template database "template_postgis" does not exist

After looking into the error it was pretty clear that I was lacking that template

After years of using a fork of emacs-starter-kit, today I decided to start a fresh setup.

My first 'real' project, in which I'm planning to use Arduino is the use of a motor to move my blackout synchronized with my snooze.

So I decided that my first step is to control a servo using serial communication to move forward or backward the motor, accordingly with my keyboard input ('s' and 'w').

Code, Assembly Video and

Today I bought my Arduino starter kit

  And I used the Fade example as Hello World

Yesterday, I started the clojure koans, and all the koans related with the data structures were to easy and showed how easy and cool data structures are at clojure, but I got my first stopper :) when I was faced with a higher order function that I'd completely forgot.

What are higher order functions?

They are functions that have at least one of the following properties

Return functions (for example functions that are mapped to other functions like Integration - Calculus)

Take at least one function as a paramater (function composition g(f(x)))

From my examples looks like I hadn't forgot what is a mathematical higher function, and the functions composition case remember me, the C/C++ feature to receive functions pointers as parameters ;) quick example at http://www.cplusplus.com/reference/clibrary/cstdlib/qsort/

My solution for the first higher order function koan https://github.com/sarcilav/clojure-koans/commit/cd2f89e5620a4a195c03d7e71e8bc8827b045345
