Queen – Don’t stop me now soulful re-edit

Freddie
One of my favourite persons ever, model of life, also i have the same shoes.
As some of you already know, I’m a wannabe producer too!
So I managed to find the original master multitracks of this song, then i re-edit it to give space to the electric bass and the chorus on the back. This is the result:

How to Enable real Bridge mode for UPC Cisco EPC-3925 with HTML Injection

A.K.A. Public (and probably static) IP address for residential UPC customers.

I have a huge bandwidth internet connection, so why don’t let my friends download or upload files to my house, it makes feel us closer, it’s funny to share things, it can be actually useful in some cases.

I live in the Netherlands and here are several companies which offer different internet connections, but the common element is that houses are built with fiber channel in mind, differently from Italy, that’s why we have actually 50Mbit in download and 4Mbit in upload. For this reason I want to try to discover, for example, whether the ip address is a static one (still the same in two months) and other funny things.
So the first thing to do is to check if the router distributed by UPC can actually act as a bridge so I can manage myself all incoming connections having a public ip address. Also I have a spare Cisco E2000 with dd-wrt that eventually can assume the public ip while the cisco turns in a simple bridge.

How to configure Wireless Lan Raspberry Headless Server

It could be useful for wlan configuration without a Desktop GUI or just from ssh client, you choose why.


The point is: you can’t do it with iwconfig, unless you have just wep encription enabled, if you use to have wpa/wpa2, instead you want to use wpa_supplicant.

VPS: Debian squeeze apt-get update returned an error code (1)

Also known as “E: Sub-process /usr/bin/dpkg returned an error code (1)“.
Well you are trying to run apt-get upgrade on a virtual private server running Debian squeeze (it can happen on Lenny too) hosted on several Xen based platforms.
It happens because grub cannot find your disk in order to rewrite your initrd image.

Since Xen kernel management is transparent to your machine itself, and it is all you need in order to boot your machine, you can remove grub with no fear, typing:

root@apple.com:~#apt-get remove grub-legacy grub-common

And yes, finally you will go to the end of your apt-get upgrade process.

Hope this can help out there!

 

Output of my machine follows:
