Rock and roll from Deep Purple's vocalist (more precisely, he was the singing bassist). The last song has audio from the built-in Canon 60D microphone with the recording level limited. It does sound rough, though, because I was filming at stage level from the side — there you get hammered by the drums from the kit itself rather than from the speakers, and everything else comes from the monitors and amps.

I decided to save this for memory: the Facebook profile of The Qemists vocalist Matt Rose — both the avatar and the cover photo are my photos from their concert at Aurora.

Twitter has firmly embedded itself in modern life, and by now even every housewife has at least heard of it, if not created an account there. Judging by my experience and the experience of people I know, you check Twitter very often during the day. Every day.

The idea came up to write a simple Twitter bot for notifications...

That was a great concert. At the time it seemed to me to be one of the best ever held at Aurora.

We climbed Teide volcano on Tenerife. It takes a little over an hour by bus to get to the base. Then we had to wait for the cable car because it was not working due to the wind. We were already thinking that we would never get there after all. But it did start working. The cable car takes you up to an altitude of 3500 meters above sea level. After that, with a special permit (I think from the national guard), which can be obtained through the website, you can climb up to the crater itself. In the end you find yourself at an altitude of 3710 meters, at the highest point in Spain. Those 210 meters along a stone path shaped like stairs were not easy. Cold, wind, lack of oxygen. You run out of breath every 20 meters and have to stop to catch it. Your heart pounds like crazy. But it is worth it. The beauty is indescribable; you are standing above the clouds, and you can even see the island of Gran Canaria from above. You do not think very clearly, but I climbed onto the highest rock I could find. The crater itself is nothing special: a rounded depression, the smell of sulfur, and in some places white smoke breaking out from under the stones. But the views there are amazing. I shot a little video. Almost without any editing, we just laid the video over music.

Today was the 3rd day of the DLD 2012 conference (Digital, Life, Design). A couple of thoughts, just to reason them through.
