# And now… Bitcoins!

The concept of the Bitcoin is still a bit mysterious for me. The idea seems fair in a general view; however, the use of it is what worries me.

Of course, when you’re using electronic means to do your transactions, you can always have a bug or something that suddenly fucks it up. I don’t want to rely my entire income in some virtual payment. Continue reading

# Songs of the day: Mambos

Haters gonna hate. As told before, Dudamel is one of those guys that either you love him or hate him. I personally love him.

He is not the orthodox musician that comes and works with precision every time. He likes to give life and to give colors to the music. Huh, I really don’t know how to explain it, I just got out of words suddenly.

Here you have a great performance and sample pieces of Mambo, a very well-known music genre of Cuba. Many composers have taken this genre and put it into big masterpieces.

Dudamel and the Youth Orchestra Simon Bolivar perform many Mambos from Perez Prado and “Mambo” from Leonard Bernstein.

Who says orchestras are not to dance?

# Song of the day: In the summertime – Mungo Jerry

Summer is escaping from Germany and the cold breezes are felt in the evenings. And to celebrate that I leave you with this hit of the cheerful Mungo Jerry: In the summertime.

First time I heard it I think I was 12 or so. It was one of the song that inspired me to make an Incursion into music. You can easily notice why. All right! Summertime, see you soon!

# A fancy visualization of planes intersecting – Part 3 (and Final)

The mystery is over! From the previous posts we have seen the way we can generate a random plane, and visualize 3 of them at the same time showing their intersecting point.

It might be enough for some simple visual purposes, but we are more ambitious than that and we want to get it fancier.

And that’s why I’m here! This final step would be to achieve a neat visualization of our three planes and even the equations involved. Let’s begin with what we have so far:

```P = rand(3);
d = rand(3,1);
x = P\d;
hold on
drawPlane(P(1,:), d(1))
drawPlane(P(2,:), d(2))
drawPlane(P(3,:), d(3))
scatter3(x(1), x(2), x(3))```

Where the function drawPlane was defined as:

```function drawPlane(P, d)
[x, y] = meshgrid(-10:10);
z = -(1/P(3))*(P(1)*x + P(2)*y - d);
surf(x, y, z);```

# This too shall pass – OK Go

Perhaps one of the most inventive Rube Goldberg machines that I’ve seen. This video went viral time ago and still receives tons of hits a day, having so far over 40 Million (as of August 2013).

The machine was designed during months by OK Go and Syyn Labs, a company that now creates all kind of similar visually impressive projects. Go check them out!

And now enjoy the music and put attention on every step of the machine progress, it is quite imaginative and entertaining to watch.

# A fancy visualization of planes intersecting – Part 2

All right, I know I let you abandoned for a bit. But the last trip to Barcelona and the ongoing final exams in the University haven’t given me any chance to keep this. But I’m gonna take some minutes to finally write about the visualization of our planes.

In the last post we analyzed how a plane is constructed given the equation ax+by+cz = d. Then, given the parameters of this equation, I showed you how to generate its corresponding plane in Matlab.

Now I’m gonna keep this post short (sorry for the inconvenience), but here we are going to set 3 planes in a single visualization. In a third post, we’ll make all pretty and fancy.

# Humiliation of a Mexican child

Not new, still outrageous. A mexican inspector of the government did one of the most humiliating acts. But well, let’s start from the origin of all.

In Mexico are forbidden (among other things):

1. Child labour.
2. Selling cigarettes or alcohol to minors.

Clear so far? ok. However, there is a problem. It is not possible to achieve it. Why? Well, in Mexico there is a high level of poverty and many people have to find some source of income, rather than going even to schools, including children. True, some children are exploited and some others just don’t have any further goals in their lives. But, although the law is supposed to guarantee the same opportunities for everyone, in reality it is not possible due to the high inequality in the country. Continue reading

# Song of the day: Ciel, che feci – Guiseppe Verdi

Two weeks ago I was in one of the best concerts ever in my life. I got my ticket since early February and it was one of the last ones. That event is one of the most famous in Munich. It is part of a complete weekend with classical music.

It’s called “Klassik am Odeonsplatz”” that literally means “Classic at Odeonsplatz”, which is a square in downtown Munich surrounded by beautiful architecture and a nice atmosphere. It takes place every summer and the most remarkable artists of classical music perform in an Open-Air concert.

This year was awesome not only because Yannick Nézet-Séguin was directing the orchestra and Thomas Hampson was the leading Baritone, but also because my favorite tenor Rolando Villazon gave one of the most powerful and amazing performances I’ve heard from him. And yeah, I was there.

The final duet with Hampson and Villazon singing Verdi’s “Dio, che nell’alma infondere” was stunning. But, for me, what really got the night was the final solo performance of Villazón, when he stood in front and sung “Ciel, che feci” from Verdi’s Oberto. And it’s obvious that he was going to sing Verdi, as nowadays he’s promoting his latests work, which goes around him.

Huh! I have goosebumps just remembering. Amazing, that’s the word to describe his interpretation. After that I just stood up and burst into applause with all my energy. But stop reading about it. Watch his great performance in the following video from 13:38.

Bravo!

# Song of the day: Harmageddon – Apocalyptica

More than a song, it is actually the melody of the day: Harmageddon from Apocalyptica is one of the first singles of the band and it is simply good when it comes to put your mind in a state of trance. I use it to study and it works for me. The rythm and pace of it awake my brain and fill it up with strong bass notes created by the cellos of these metal-lovers. Hmmm… Check it and convince yourself.

# Song of the day: Rap-O Clap-O – Joe Bataan

I’ve been very funky lately. Mostly due to the stressed time in the University, I just need some happy mood to shale my head in the library of the Uni. I don’t feel that alone among the sea of geeks like me… perhaps I should not write that. Anyways.

Cheer up with Joe Bataan!
