I found out it's really easy to setup in Fedora; even with SELinux and all. Here's a straightforward howto:

# Get BFGMiner
git clone git@github.com:luke-jr/bfgminer.git
cd bfgminer

# install deps
su -c 'yum install -y uthash jansson jansson-devel …

Ok, when I say "low on memory", I mean less than 512 MB of RAM. My particular installation was on an old Dell; with ~384 MB of RAM.

Yep, it will take long. Yep, you will suffer. Yep, it works fine!

So, first of all, get Fedora's LXDE live CD …


Wanna install Fedora? (release, alpha or beta) Use BFO!

Guys, I really like BFO. It's cool, awesome and, in the end, you will save a lot bandwidth not only to you, but to the mirror Community.

Yep, bfo is easy to use: https://boot.fedoraproject.org/

It's kind of a net install but it's not married to any specific …


The Fedorian Dare

Ok, when I first installed http://www.linux-noob.com/screenshots/fedora/1/post/index.html, I got "all crazy" and installed KDE, XFCE and GNOME all at once!

It was quite an experience. I had a pentium 4 (1st gen) with 1 GB of RAM (133 MHz or something) and …


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 …

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.

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?
