I would like to show you how to make a presentation just in HTML. With the tag ‘canvas’ you can create nice effects for texts. But also you can create effects for showing photos.
First you have to define the slides:
var slide0 = function()
{
initSlide(true);
h2("Google Technology User Group");
line("5 februari 2010")
};
Last year Tim Berners-Lee called for “raw data now” — for governments, scientists and institutions to make their data openly available on the web.
At TED University in 2010, he shows a few of the interesting results when the data gets linked up.
Last week I was pondering about the iPad and I had to think about a book I read back in 1995 : Being Digital, Nicholas Negroponte. I looked up the book and browsing it. Suddenly I found the page I was looking for : Personal filters. The following paragraph was really striking:
“Imagine an electronic news delivered to your home as bits. Assume it is sent to a magical, paper-thin, flexible, waterproof, wireless, lightweight, bright display. The interface solution is likely to call upon’s years of experience with headlining and layout, typographic landmarks, images, and a host of techniques to assist browsing. Done well, this is likely to be a magnificent news medium.”
Sounds like a iPad….
Further in the chapter Nicholas Negroponte is describing a new kind of electronic newspaper. News filtered by your own interests. For example your reading behaviour on a sunday is different than on a monday. So you are also interested in different kinds of news.
Linked Data, a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF. Such exposed data and computers like an iPad will give Personal Filters a bright future.

For my latest project ProboGen, I needed the functionality to create and zip files. I found this this groovy code and show its show how powerfull groovy is.
File.metaClass.zip = { String destination ->
def result = new ZipOutputStream(new FileOutputStream(destination))
result.withStream {zipOutStream->
delegate.eachFileRecurse { f ->
if(!f.isDirectory()) {
zipOutStream.putNextEntry(new ZipEntry(f.getPath()))
new FileInputStream(f).withStream { inStream ->
def buffer = new byte[1024]
def count
while((count = inStream.read(buffer, 0, 1024)) != -1) {
zipOutStream.write(buffer)
}
}
zipOutStream.closeEntry()
}
}
}
}
To zip up a directory you can now just say:
new File("/data/ft/").zip("/ft.zip");
This is really neat solution.
Thanks to : powerful groovy
Last night my presentation about Google Maps & Charts for the Dutch GTUG is uploaded on Youtube. See video : Google Charts & Maps
We had a great GTUG last night. Interesting talks, pizza & beer! And of course I got my swag!
Today I will give a presentation for Dutch Google Technology User Group. The presentation is about Google Maps & Charts.
I’m looking forward to it. So if your in the neighbourhood, just come along!
From “Java: What does its future hold?”
Java coders are also limiting the incursions of these new languages by borrowing many of the best techniques and folding them back into Java. Many of the simple declarative patterns from Ruby on Rails were explicitly imitated by Grails, a framework that glues together scripting extensions such as Groovy with database middleware called Hibernate. Groovy itself adds many more dynamic options for code interpretation while linking directly to any part of the Java API. There’s no need to even consider Python or Ruby because Groovy lets Java programmers enjoy the seemingly endless variety of a huge library and the rock-solid VM at the foundation with a sleek, modern syntax.
I totally agree!
Yesterday my first article was published on Computable.nl (http://bit.ly/2mnHGl) about Deliberate Practice. It’s about how to improve your skills.
I always had different mentors to improve my own skills. For programming (I started at age 11, a Commodore VIC-20), for swimming, secondary school, for my study Computer Science. So I say : thank you all!!
