Great videos – Iron Maiden Live 1981

This awesomely remastered video of Iron Maiden performing live in Germany from early 1981 is just amazing. Shows the roots of the band and justifies Paul Di’Anno saying it was a metal punk band. And most songs sound even better than the studio versions. A truly brilliant performance of four gifted musicians and a great singer. Clive Burr on drums just rocks. Just listen his take on Phantom of the Opera.

The original line-up:

Steve Harris
Paul Di’Anno
Dave Murray
Adrian Smith
Clive Bur (RIP)

Enjoy, you won’t find such great quality video from the early days of Iron Maiden. Their music is crystal clear thanks to great sound mixing. Kudos to the German TV show ‘Beat-Club” that recorded this gem at the time. This is metal history:

Tracks:

00:00 The Ides of March
02:10 Prowler
05:56 Charlotte the Harlot
10:40 Wrathchild

“Tears for remembrance, and tears for joy
Tears for somebody and this lonely boy
Out in the madness comes the all seeing eye
Magget flickers above us, to light up the sky”

Up the irons!

Great Movies: District 9

District 9 is one of these movies that tell you a lot of real-world stories using exotic, if not superficially irrelevant, metaphors. In this case, the metaphor is simple: aliens have come to our planet, but without a clear purpose (peaceful or not). Rather, an alien mother-ship appeared over a South African city one day in 1982 and stayed there until the humans decided to enter and investigate what’s in there. What they found was thousands of alien insect-like beings without a leader, without food, without something to do or go. They looked… stranded thus the human government decided to confine them initially in a camp, called District 9, just outside the city…

How to get free signed SSL Certificates and setup secure domains in Apache and Debian

This how-to describes the process to obtain 100% free, signed SSL Certificates from StartSSL.com and configure Apache in Debian to use these SSL certificates in your virtual domains, so that people can access your site(s) through https (i.e. https://example.com) without ever having the browser tell them the scary “this site isn’t trusted” anymore.

Before you start, you will need:

  • One or more of your functional domains which point to a server you own and have root access to. In this tutorial I’ll be using my wife’s supersyntages.gr as testbed.
  • A browser, for this tutorial Chrome, although you might prefer Firefox (see below why).
  • Root access to your server with Debian and Apache installed, with the above domains configured as VirtualHost.
  • The openssl package installed in your computer.
  • One of the following emails configured in each of the domains you want to include in the SSL certificates:
    [email protected]
    [email protected]
