.openFoundry top-level concepts

For the .openFoundry organization we are trying to come up with a good model for the members to attach their projects to. Going from the idea of local groups of people coming together all the way to providing a resources, communication and organization platform. From initial ideas was in the spirit of just come together and have some fun with technology it has to grow into a statement that will the basis off all our top level activities.

How do you create such a statement? long talks, heated discussions, concessions and finally Consensus!

.openFoundry kickoff

This weekend the kickoff of the .openFoundry took place at the revelation space in the Hague. The .openFoundry was initiated by Bert Meerman to create a new foundation. The foundation would act as an open-source platform for projects. The projects can be anything that has to do with technology any the broadest sense of the word. Project run from a web-store for Linux packages all the way to a frame-less laser harp.

The idea is to work together on new ideas and technologies.

jQuery plugin: tagEditor

This month I’ve been working on an existing jQuery plugin called tagEditor. It is a plugin that turns an ordinary text input field into a dynamic tag tokenizer. The idea is that it can be used as a tag input or edit form control. It interacts a lot like the tag editor used here in WordPress or other popular tools that use tags. Tags are separated by a separator (most commonly an enter or ,) and then transformed into a list where the tag can be removed by clicking on it. It is usable together with an auto-complete (the jQuery UI auto-complete works well) to create the perfect user experience.

Together with the plugin’s original creator Karl-Johan Sjögren version 1.4 has been developed and released. More details can be found on the jQuery plugin page and on the demo page by Karl-Johan.

Dynamic coloring with Sass

When building a web-application you’ll need to do some sort of styling to get it looking a kind of decent. To enhance your web app you would probably like to do some more advanced styling with lots of css, images and other stuff… But what if you needed a styling system that dynamically changes the colors of your style?

I’ve designed and implemented an application that uses Sass to created dynamically colored styling for such a system!

Hacking anything

Hacking… What is the first thing that comes to mind when you hear the work hacking? Well, most of you will probably think about getting illegal access to a secured system. I’m not talking about that kind of hacking!

Hacking is the beautiful art of using something in a way it was not intended by the creator of it. A great example are SMS text messages for mobile phones. These were originally developed to as a way for mobile operators to send service messages to there clients. Then somebody found out how to use it so send messages to somebody else. This was not intended by the creators of SMS. But it did become the main use for the that particular service!

Fosdem 2010: the aftermath

One campus, 2 days + some nights, about 250 sessions and +5000 geeks. The European meet-up for the open-source people!

What was my part? Following sessions, supporting in one session and talking a lot to all the people I know and don’t know within the community.

What I took away from it? 4 t-shirts, 5 buttons, loads of stickers, new knowledge/information, new ideas and lots of new cont(r)acts.

The short story is: arrive Friday around 5pm, get to the Renaissance Brussels hotel, get something to eat before going to Delirium, finding people to talk/drink with, get to bed, wake up and get myself to campus, follow some sessions, support on the CBAC session, get myself to the joostians (former Joost Technologies employees) dinner, have some drinks with the joostians, get to bed, wake up and check out of the hotel, get myself to campus and plant myself in the back of the mozilla room, follow some other sessions afterwards!? and get my ass back on the train home.

Today I created the ALPHA stying for CBAC (Context Based Access Control). CBAC is a security gem for Ruby on Rails and adds an extra abstraction layer to the well known RBAC (Role Based Access Control). With CBAC you can add context based security to your Rails app in just a few simple steps. I’m proud to be the first to blog about this new security system for rails!

Prototype: GeoTweets

4 bottles of coke, 3 days and a lot of mashed code. That is how much it took for me to roll out the first prototype of GeoTweets. GeoTweets is an web-based application to show Tweets about a location on a map. Using the Google maps API v3 as a map and gathering the tweets with the Twitter search API allows the application to show tweets on a location about that location.

The concept for this prototype was created for the course Multi-media systems at Leyden University (Netherlands). The initial concept was to show what location on the world most tweets were about. Due to technical limitations this evolved into an application that lets user click to find out what is happening on a location. The locations are saved together with the activity ratio, this is then displayed on the map as active active and recent locations.
