Installing Gource from Brew/Mac OS X

Por
Do you know Gource?  Gource is a magic visualization tool for source code. It tracks all activities in source code repository to create an animation that represents the its evolution.

http://code.google.com/p/gource/

Very effective to show your work for your partners and bosses.
But... I had bad time to install gource using Mac OS X.

(brew is too a fantastic tool. It allow you install thousands packages almost as easy as debian apt-get). But, for brew...

nano-belt:~$ sudo brew install gource
Also installing dependencies: pcre, glew
==> Downloading ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.12.tar.bz2

curl: (78) RETR response: 550
Error: Failure while executing: /usr/bin/curl -f#LA Homebrew\ 0.8\ (Ruby\ 1.8.7-249;\ Mac\ OS\ X\ 10.6.8) ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.12.tar.bz2 -o /Library/Caches/Homebrew/pcre-8.12.tar.bz2


Arrrg... brew can't locate an pcre from remote server. For our luck, brew has  a fantastic way to avoid this problem. Simply, create your own formula to brew install pcre:

sudo brew create ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.30.zip
Version detected as 8.30.
==> Downloading ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.30.zip

Beautiful!!!

Now, you can go forward with installation process...

Note, you could also publish a new formula for everyone in internet using submitting system, but brew recommed you `brew audit pcre` before submitting, thanks.

Let's take look in installation process once.

Oh my... it isn't enough.

You try the following tricks:

1) Install anything from git. Use brew install 'git-url' and edit <your-package>.rb (yeah... formulas are ruby files) changing url (method) to head.
2) Oh wait. Try the simplest command. brew update and try install again. ;)

Expressões, preconceito e racismo

Por
Expressões preconceituosas e racistas Antes de alguma outra frase, primeiro peço licença para falar de mais um assunto do qual não domino. Falo por acreditar que um leigo presta serviço maior ao debater assunto com base em fontes (ainda que seja uma Wikipedia) e no pensamento lógico do que simplesmente se manter mudo a questões do cotidiano. Em voga agora está em falar quais são ou eram as expressões preconceituosas e racistas que até a pouco eram toleradas em muitos meios. Como é covarde dizer que em boca fechada não entra racismo. O racismo não é perpetrado apenas por quem profere mas por quem se cala à agressão perpetrada a outrem. Mas veremos que a questão é muito mais complexa que os cães raivosos do politicamente correto querem dizer. Tomo aqui a palavra racista, como sendo algo usado para impor a dominação de uma “raça” sobre outra. Portanto, a acusação de racismo vai muito além da mera acusação de preconceito. Não tenho o menor apreso por vitimismo barato, onde expressões q...

A hard logic problem - The escape of blue eyed vampires

Por
Once upon a time, a vampire clan lived peacefully on an island (as long as vampire clans can live peacefully). Then, a demon lord came, overwhelmed the vampires and became the ruler of the island. The demon didn't want any vampire to escape so he created a gargoyle to guard the only way out. This gargoyle was a fantastic creature, so powerful that he was kept petrified for the whole time until a vampire appears. Then he awakened and started to fight until seeing no more vampire "alive" (as far a vampire can be alive). All vampires crazy enough to try were killed only left a hundred of vampires. There was a catch, of course. The gargoyle was not perfectly designed. It did not awaken when blue eyes vampires appeared. And all remaining vampire were blue eyes but as you know vampires cannot see him/her selves on reflections. For any reason, they were not aware of their eye colors. Besides all that, blue eyed vampires didn't like each other (so they would never say ...

Curry with JS

Por
Partial application and currying with Javascript In the strict way, currying is the technique of transforming a function that takes multiple arguments (a tuple of arguments) to one function that receive only one. In such way, currying techniques allow transform one multi-parameter function in a chain of functions, each one with a single argument. Looks complicated? Blah.. it is not true. In this little article, we are actually more interesting in partial applications. Let’s take the Mozilla Example for replace function in String. As we know, we can use a “replacer” function as paramenter for replace method in String object. Let’s say that we want to split a String defined by a non-numerical part, a numerical part and finally a non-alphanumeric part. Here is how: function replacer(match, p1, p2, p3, offset, string){ // p1 is nondigits, p2 digits, and p3 non-alphanumerics return [p1, p2, p3].join(' - '); }; We can try it as usual… var newString = "abc12345#$*%...
