Benchmarks: C Vs Perl5.16 Vs PHP5.5 Vs Python2/3 Vs Ruby2

Oh, today is a sad, sad day for me.

Ruby seems to be as slow as Python3; which, in my previous benchmark: https://gitlab.com/renich/benchmarks/ was not! It was just between PHP and Python2.

Not the published one but, I remember, ruby was around 400 ms... damn... really …


Haciendo mejor FOSS que nunca

Hola, lector desconocido al que le gusta el FOSS,

La neta, acabo de leer un comentario que me inspira. No por bueno; es uno de esos comentarios de un usuario que espera que el FOSS sea mucho mejor, pero que no piensa hacer nada para mejorarlo: un consumidor.

HowTo: Configure Gitolite3 on Fedora 19

Ok, Fedora adheres, thankfully, to the FHS a lot and, thus, changes where things might go. In this case, they don't use the git user; they use gitolite3 as a user. And, in a nutshell, here's how to configure it:

The first part of the HowTo goes on the Server …


Synapse: Should it retire from Fedora?

Hello, Fedorian Community!

I started maintaining Synapse in Fedora back in GNOME 2.x. It seemed like a great idea. It used Vala; no Mono and stuff.

Today, it seems abandoned:

I'd like to retire the package to …


Howto: Check if a browser has CACert installed as an authority

Well, I am working on a project to sell virtualization instances, a.k.a. vps, in http://bitcoin.org/.

Anyway, that has nothing to do with this. The thing is that I decided to go for http://cacert.org/ certificates. Why?

  • They're free

My trip to Archland (Arch Linux)

I am an infamous Fedorian. Everybody who knows me, knows that. I love Fedora. Been with it since Fedora Core 1 and never left it.

This said, I just made a trip to Archland! I try to use some other distros between Fedora releases. The list of distros I have …


Fedora 19 up and running!

Yep, just upgraded. It's 5 AM and noticed the mirrors there.

fedup --network 19 --reboot

That was it. The production, testing and devel servers went down and up in 378 pings (1 sec per ping). This …


HowTo: Use ip instead of ifconfig

The other day, I was helping out some guy to set his IP address. He missed ifconfig; which is deprecated by the way, and I lent a hand; helping him get around the "ip" command.

Here's a micro cheatsheet:

Migración a NginX

Me da gusto anunciar que http://woralelandia.com/ y el Servidor de la Comunidad han sido migrados a http://nginx.org/!

Antes, usábamos http://cherokee-project.com/; pero, al ser olvidado por su creador, pues, no nos queda más que migrar.

Además, creo que NginX tiene varias cosas muy suaves. Me …
