Chisme

Ayer, estuve en una reunión en la que participaron personas de CoNaCyT, Infotec, Red Hat, varios individuos acérrimos proponentes del código libre en México.

La reunión trató sobre un tema en particular: Las nubes en México.

Resulta que hay poco conocimiento al respecto. Además, hay poca oferta y poco …

Actualizando la imágen de instalación de Fedora

Refrescar la imagen de instalación de Fedora no tiene chiste. Por lo menos no tanto chiste como generarla.

Aquí va como:

# te haces root
su -

# instalar herramientas
dnf -y install livecd-tools fedora-kickstarts

# generas un area de trabajo
mkdir workdir
cd $_

# copias lo necesario
cp -r /usr/share/spin-kickstarts/* .

Howto: IPFS on Fedora 34

I like IPFS a lot; for many reasons.

  • They're distributed.
  • Support newer technologies (quic, for example)
  • Enable a descentralized web.

Besides that, it's a pretty convenient app to use once you get the hang of it. You can either go full CLI on it or just user it from the …


HowTo: Generate free SSL certificates for Nginx/Tengine with LetsEncrypt

OK, it's fairly easy to get this done on a distro like Funtoo/Gentoo or Fedora, which are the distros I use.

First of all, you need to install this thing on your server:

# Fedora
su -
dnf -y install letsencrypt

# Funtoo/Gentoo
su -

HowTo: Compilando crystal en Fedora 22

Me ha interesado mucho el lenguaje de programación crystal: http://crystal-lang.org/.

Este lenguaje tiene la sintaxis muy parecida a Ruby; si no es que igual. Parece que hasta el Matzu; creador de Ruby, es fan del proyecto.

En todo caso, para compilarlo en Fedora, hice un script. El script …


Funtoo

Ok, just to announce, in case anybody cares, that I am a dual resident now. I have Funtoo on my desktop (the PC I use most) and Fedora 21 in my laptop.

Usually, I write all my articles for Fedora but, for now, I will be writing them for both …


HowTo: How to use your jack audio card with pulseaudio in Fedora 20

I, honestly, don't know what's happening here. I dunno if you're delegating pulseaudio to jack or viseversa. Anyway, I use this method to enable my http://us.focusrite.com/usb-audio-interfaces/scarlett-18i20 in Fedora 20. I hope it helps out:

Procedure

#!/usr/bin/env bash
pulseaudio -k

HowTo: Create an interface configuration with nmcli on CentOS7 and Fedora

I ran through hell today!

I tried doing things the old way. You know; edit /etc/sysconfig/network-scripts/ifcfg-eth1 in order to set it to a static IP. Well, bad idea.

I had all kinds of problems when the two interfaces where online (eth0 and eth1). For example:

  • eth0, even …

HowTo: Two different public IPs on a single server

Ok, today, I discovered I am still an http://en.wikipedia.org/wiki/Idiot.

Yep, I tried to add 2 public networks to one of my CloudSigma servers and one of them didn't work.

I thought everything was to blame but my configuration (as always). Well, I managed to discover …
