Friction powered Longboard
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…

Anderson.Paak dances with us in Berlin
Great concert in Lido with Herr Paak. 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…

Learning DOCKER #1
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…

New project: Portable Flettner-Rotor (Longboard)
3D model available on tridiv.com The idea come while reading “Symmetry of Sailing” by Ross Garret. The german engineer Anton Flettner was the first to use this physical principle as propulsion engine for a ship in 1922.

At the start of this year I got tired of Spotify advertising and I got a premium account. So I started making public playlists and sharing with the friends at work and posting it sometimes the new editions in Facebook and Twitter. This generated some good feedback so I though about sharing some of them…

Good architecture and why not to render Controllers inside Views
In Symfony, Zend and other frameworks you can rend a controller inside a view like this: {{ render(controller(‘AcmeArticleBundle:Article:recentArticles’, { ‘max’: 3 })) }} Creating and Using templates documentation here. Just because there is a possibility to render(ControllerMethod,{ params}) in a template doesn’t mean you have to use it. Doing so leads almost always to a…

Symfony Bundles that come always handy for Admin Panels
After a quite accidental start with the Framework I’m enjoying a lot developing stuff with their Form component. Using bootstrap and almost without any front-end javascript one can build great Admin-dashboard forms, using only a : {{ form_start(form) }} {{ form_end(form) }} Where you want the form to be rendered in the twig template. As…

Here is a brief 3 points summary of things I would like to change in my next projects: Using Constant instead of variables in…

Sonata-page Bundle CMS
At this point I was going to make a full stop and try to make a step by step installation, that is easy to configure and also self-understandable. But I come to the point of so much trial and error, apart of learning all the command-line stuff and reading installation procedures, that there is no…
