Gather linux system information with inxi

I've discovered this great command-line to gather system information:

inxi -F

And here is the output:

How to create a CentOS 6.5 Vagrant box (with VirtualBox)

This guide is inspired from the Vagrant official documentation.

Versions

Vagrant: 1.6.2
VirtualBox: 4.3.12

Creation and configuration of the virtual machine

CentOS 6.5 installation

Launch VirtualBox and create a new VM with:

CPU: 1 core
Memory: 512 MB
Storage : 200 GB (dynamically allocated)
No audio, no USB

Tips for ~/.ssh/config file

You can add SSH client configurations that can ease your life a little bit. Here are some tips you could put in your ~/.ssh/config file.

Host *
HashKnownHosts no

Host *.example.com
ServerAliveInterval 300

PostgreSQL Installation

Basically, to install the latest version of PostgreSQL (9.3 as I write), you can follow the instructions in the PostgreSQL Wiki.

Post-installation commands

Initialize

Here is a difference from the wiki: I customize the call to the PostgreSQL script initdb (adapt the paths if needed):

Mount a Nexus 4 on Ubuntu 12.04 LTS

Install the package mtpfs:

sudo apt-get install mtpfs

Create a directory somewhere (eg: "android"):

mkdir android

Mount :

sudo mtpfs -o allow_other android

Unmount :

sudo umount android
