I needed a virtual machine for debugging some Python memory leaking software without risking the health of my Ubuntu system. VirtualBox was my first choice because of its ease of install (just “apt-get install virtualbox”). Since I wanted to access the VM via ssh (instead of using the VirtualBox console) I found a bit annoying […]

It took me some time to find out how to do this, so I’ll post it here hoping that someone will find it useful.
First of all, “fidsk -l” won’t show all your FreeBSD disklabels, you’ll have to do “cat /proc/partitions” to find the partition you wan’t to mount. If the Kernel has support for disklabels […]

Have you ever ssh’ed into a remote server and wondered if you could run a program using the connection from that remote server in a transparent and easy way?
Well, you can and it’s quite simple. Here’s the recipe for Linux.
1. Install tsocks using your Linux distribution package manager (preferably) or compiling from source.
2. Add a […]

Are you using Mutt and wondering whether it’s better to use mbox (mailbox) or maildir for mail storage?. I hope this post will help you decide.
Here I publish a simple benchmark results of the time it takes mutt to read/open a folder with 28.000 emails.
First, some notes about the tests:

software: mutt 1.5.13 compiled with […]

Have you ever stumbled upon a semi-frozen Linux server without being able to reboot it because of some processes waiting in uninterruptible sleep for some I/O, while still being able to login through SSH?
I have. More than once. So why not just force a hardware reset, writing some garbage to restricted I/O ports or memory […]

Una interrogante que surge comúnmente a la hora de implementar un módulo de Linux es que mecanismo elegir para configurarlo. Desafortunadamente para algunos (y afortunadamente para otros) existen varias (quizás demasiadas) alternativas para ello. A continuación presento un resumen de ellas, junto con una comparativa.

Desde hace un tiempo vengo usando FreeBSD en algunos servidores. Al principio me sentía un poco reacio a probarlo porque pensaba que el constante aumento en la calidad de las distribuciones Linux provocaría, tarde o temprano, la caída de FreeBSD y por lo tanto no justificaba invertir tiempo en estudiarlo. !Cuan equivocado estaba!. FreeBSD podrá […]
