This is a redesign of the Rotor Flettner project. The effect works after testing it mounted on a windsurf board but it has a potential flaw: Magnus effect has a smaller force than the wind pulling you to the side. The result is that you go more in the wind direction than in the direction that you really want to go. The equivalent to having a very small sail.
But anyways it was a lot of fun to make it and having already the engine and the structure to mount it I thought, why not to try doing something with it :)
And it works, went about 2 kilometers back and forth after discovering I made some design errors and that friction is not my friend. Engineering lessons learnt:
1.- Control cables of the engine should not be touching the floor
2.- Engine should transmit power using some similar material as the wheel
3.- Friction generates heat and 50% of the battery or more is wasted (maybe good for the winter)
Only bad detail: The sound in LIDO. I know that in small shows is almost impossible to have a great acoustic. But I heard Robert Glasper in Festsaal Kreuzberg 2 years ago, and it was just awesome sound. Leaving out the differences, since Festsaal was 90% wood, and thus a great acoustic natural place this time the sound people at Lido did a poor job. Or just the sound system is not prepared for a show like this. Could hear his voice almost always in the background, without a different output channel and always mixed with the bass and the percussion.
Anyways a great performer with a cool band, great DJ and a highly recommendable show. Proud to be dancing with you Brandon!
Docker is an exciting technology since April 2013 when it started as open source project. But is only since last year or so that I started hearing more and more about it. And it’s mostly because some companies like Zalando (Berlin) , Spotify and Netflix started implementing it successfully in their servers.
The Docker Mantra is the following :
Build, Ship, Run
Any App, anywhere!
I’ve started trying in my Ubuntu 14 machine with this tutorial:
Nach letzes composer update, ich kriege immer diese Meldung nach update /install : “You are running composer with xdebug enabled. This has a major impact on performance and will break your balls”
So ich habe die richtige Lösung gefunden und wurde mit euch teilen:
$ php -i | xdebug
Guck mal welche config ist schuldig, in meine Ubuntu ist:
Und einfach comment:
Voila! Deine composer is viel schneller ab jetzt. Für mich ist ungefähr 3x schneller.
I’m sure this happened to you too. After searching for something on the internet, banners showing exactly this product are following you on any other website you visit. And specially on Facebook!
Because you surf the web with Facebook open don’t you ? Then you must be aware that on 90% of any website there is some kind of facebook plugin. That means facebook knows almost all the sites you visit.
Now why don’t to use this power for our own benefit ?
