About 15.30 the Parlament ha aproved the new Catalán Republic with 70 YES votes and 10 NO votes. What happens next no one knows.
Since I lived in Mallorca for about 12 years I always dreamed to come back to Spain next to where my fathers live in Catalunya, near Arenys de Mar. So now I’m quite worried about what is going to happen next. My wish is that whatever happens next is without violence and represion like in 1-O vote. Violence can never be the answer to anything.
Shibboleth is an open-source identity federation solution that’s used in research and education communities worldwide.
Basically is a federating agent that consists of 2 components:
1- Service Provider (SP)
which request attributes, represented in this implementation als storage.luckycloud.de using Apache2-mod-shib
2- Identity Provider(IDP)
which broadcasts attributes, and will be implemented in the Login-logic of the site
Now the SP is actually out-of-the-box with apache2 module mod-shib. But my interest here is to do the Identity Provider part als Symfony module.
Is someone else out there interested on following the implementation ?
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.
The still difficult part and open points to discuss that I have in this Winter project are:
Material to use in the main structure. The goal is that is light, when possible less than 10 Kilos, but resistant since it needs to provide lift.
Motor weight: 170 g Speed controller: 230 g . Cables + Battery: Aprox. 2 K. Making a total of 2.5 Kilos weight.
Still open to discuss: At what speed needs the cilinder to roll and what would be the ideal diameter to provide enough momentum to move 70 Kg in a Longboard (I thought about 40 cm diameter).
The chain relation between the motor and the cilinder to have the right speed and force. Ex: 10 spin motor: 1 spin cilinder
And to end the question: What kind of lift will this generate on a 10 Knots wind, coming from the optimal point, let’s say 90 degrees left or right from the cilinder.
