That’s not the biggest problem with the design though, that is that the active area for the close button is bigger than the button itself. Look at the image below:

You might think that there’s a bit of titlebar to the left of the close-button, right? So you could think that you could click-and-drag here to move the window, right?
Well, if you try to do that, the window will close! The close button goes all the way to the edge of the window, even though it doesn’t look like it does.

I hope this will be fixed prior to release of the final version of Ubuntu 10.04

Knowing that Macs use the same printing system as Ubuntu, I assumed that this would be complicated as well, so I had postponed it for some time. This week I finally got to setting it up, and it was really simple.

I didn’t have to enter any information at all, it was just a matter of clicking four buttons.

Start the printers control panel from the System menu. This reveals the following window:

1. Click the “new” button (“Ny” in Norwegian).  This revealed the following window:
   
2. You don’t have to enter anything, just click “Forward” (“Framover” in Norwegian). The configuration wizard then asks you to verify some settings, like the name of the printer:
   
3. Still, no need to change anything. Just click “Use” (“Bruk” in norwegian)
   
4. Now click “Yes” if you want to see the glorius and colorful ubuntu test page coming from your printer.

That’s it. Who said Linux where complicated?

I later used the information revealed by the Ubuntu (and Fedora) printer configuration tool to help out my collegues figure out how to set up the printer on a Mac, and in Windows Vista.

So I bought it.

The magazine was priced to around £7, which would translate to about 74 norwegian kroner, or €8.20. But at when I got to the counter, I had to pay 210 NOK for it, which is about £19 or €23. In comparison, one years subscription to the magazine is €29.90 if you live in Europe outside the UK, which would include Norway. €29.90 is 269NOK or £25.5

This is a total rip-off. I understand that Narvesen needs a margin for magazines with a narrow group of readers, but this pricing is insane.

First out was Python 3.1. It was released June 27th and features

• An ordered dictionary type
• Various optimizations to the int type
• New unittest features including test skipping and new assert methods.
• A much faster io module
• Tile support for Tkinter
• A pure Python reference implementation of the import statement
• New syntax for nested with statements

Next out was Mozilla Firefox 3.5, which was released earlier today (June 30th), most noteworty items from that release is the @font-face css-attribute, that allows web-designers to bundle custom fonts with their website designs, and use custom fonts in their design.  I have used that feature to change the header of my blog, you would se a grudge font if you use the new Firefox or Safari. They have also released a new javascript-engine, which they claim to be a lot faster than the old one. Also, support for the <video>-tag has been added.

Then last, but not least, the long awaited PHP 5.3.0 has been released, which provides namespaces and closures for PHP.

One of the things that have happened is that I attended the “Skolelinux developer summit” or Debian Edu developer summit here in Bergen, with the goal to do some real contribution to free software. I didn’t end up contributing any code at that event.

Cecilie had asked Knut Yrvin to do a talk about community based projects, which inspired some of the other attendees, Walter Bender, to talk about his organization, Sugarlabs. Sugarlabs organizes the development and promotion of Sugar, the user interface for the One Laptop Per Child (OLPC) project.

from sugarlabs.org, click the image to show the whole series in context.

Sugar is an user interface aimed at kids and learning, rather than changing the learning process to use the computer and the web, it changes the user interface, so it is suited for a classroom environment. That being said, using sugar will probably revolutionize the way learning is done in the classroom, to a much more collaborative approach. Everything in sugar is made for sharing between the pupils and/or the teacher.

I had seen some screenshots of Sugar before, but I was totally blown away about the collaboration part of the system, and also how it changes the approach to computers, where we make the computer suitable for the classroom, rather than making the classroom suitable for the computer.

My contribution during the developer summit ended up beeing translating the Turtle Art activity into Norwegian, and helping Mr. Bender finding some bugs.

Since then I’ve translated the download pages on the Sugarlabs wiki into Norwegian. Sadly the current state of Sugar is that it’s quite buggy as “Sugar on a Stick”, completely broken in Ubuntu, and probably somewhat buggy in Fedora.

Also, listen to the Episode 66 of the FLOSS weekly podcast about the implementation of the OLPC in Nepal, which goes more into detail about Sugar.

Våren er på vei…

Let’s see how this can be done in different (high level) programming (or scripting or templating) languages.

Java

Java has multiple list implementations, lets start with the most basic one, the builtin array.

int[] A = {1,2,3};
int[] B = {4,5,6};
int[] C = new int[A.length + B.length];
int counter=0;
for(int e : A){
  C[counter]=e;
  counter++;
}
for(int e : B){
  C[counter]=e;
  counter++;
}

or with an ArrayList:

/*Dropped importing the correct classes, 
and constructing the ArrayLists A and B, since thats not the focus here...*/
List<Integer> C = new ArrayList();
C.addAll(A);
C.addAll(B);

PHP

So, how is the same done in PHP?

$A=array(1,2,3);
$B=array(4,5,6);
$C=array_merge($A,$B);

Python

And at last, how does the Pythonistas do this?

A=[1,2,3]
B=[4,5,6]
C=A + B

Note: the rubyists use the same approach.
