Let us start with a screenshot:

The graph itself is not something new, since I just recreated SquirrelFish Extreme comparison (against its predecessors). The focus is actually the tool which was used to generate that bar chart.

For the code and a little explanation, check out what I wrote on Qt Labs on the topic of QtScript-based bar chart.

New year means some snow and cold noses here in Warsaw, and a new job to me, this time in the mobile industry, what has rather diversified my day, and that's good.

But I am on the KDE board too, it's not going to change. What's recently time-consuming for me is refactoring of the Native Kexi Forms. The most serious and anticipated decision is dropping the (implemented in 2004..2005) idea of the forms component reusable at a rich API level for other applications. The idea has introduced too man layers after months of development, too many to have things maintainable, with just proof-of-concept KFormDesigner being the only app using the framework except Kexi.

Since 2005 things have changed, Qt Designer gained its own reusable libraries. Before someone asks - we don't use them in Kexi Forms not just because that would affect the licensing (LGPL) or because of backward compatibility required by the current Forms' XML format (which is ~95% the same as ...read more...

Took some nice vacation from IRC in the last week. Now back on track again. In the current todo list:

• Implementing the Jukebox ideas
• Work on more PyQt videos

Also found the third eye: Can you find me in that ?

If you wrote a KDE usability report in 2008 (or know of one someone else did), please send the document or a link to the document to the KDE Usability Mailing List. It will go on the KDE Usability Project reports page.

The past year brought some exciting advancements for the Linux operating system and open source software.

• cmake $target/fast
• cmake install/fast

Just like Jim Rohn said: Miss a meal if you have to, but don't miss a book, these days I force myself to read more books more often than before. Here is a list of English fictions that I managed to read fortnightly, in the order of my preference, just in case you are looking for good books and want to read some of them as well.

• Paulo Coelho's The Alchemist. I always wanted to finish this one and finally I did. Needless, it is only one of its kind. At one point in your life, you simply need to read and digest this book, because there is just Santiago in each and everyone of us.
• The Kite Runner by Khaled Hosseini. I wrote the short review before. I also watched the movie, but the movie was not even close to the book.
• The Curious Incident of the Dog in the Night-time, an award winning book from Mark Haddon. ...read more...

Getting weirded out because some people claimed to have "cracked" the Hyves Desktop application Arend, Girish, Roop and had managed to release just before the holidays began. And not only that, they put the cracked version of Bittorrent and Usenet. As if there was anything to crack... And we're still trying to convince the Powers that Be that making the whole thing GPL would be a Good Thing, since it would be a nice demonstration of Hyves' public website API, as well as a morally good thing. Plus, we wouldn't have to provice binaries for all varieties of Linux, which is quite hard, really.

Becoming quite seriously worried about the outlook for 2009. Well, that goes without saying... But we're directly influenced by the current problems, since we bought a new house in 2007 and still haven't managed to sell the old one in 2009.

A blog entry by Jure Repinc tells us about some of the new features in KDE 3.5 which according to this schedule isn't quite finished yet.

• show all cpus (for computers with multicores)
• tooltip updates continuously
• nicer visualization (maybe needs some more tweaks)

Trolltech has just released Qt 4.1. Many new features were added since Qt 4.0, including integrated support for rendering SVG drawings and animations, a PDF backend to the Qt printing system and a lightweight ...

I think the title say it all.
so I wish everyone to have a nice year 2009, with
everything one might desire ....

• I'm going in completely blind here, and have no idea if this will work across distros - it could easily simple fail for most people at the first hurdle.


• A chroot is not as insulated as a VM - in particular, processes started in the chroot are not separated from those started outside the chroot.


• Again unlike a VM, it's possible for apps in a chrooted environment to e.g. crash/ lockup your X session.


• Based on John's blog here, it seems at least possible that the chrooted KDE4Daily session won't run concurrently with an existing KDE4 session, which is a big shame, if true.


• I have some difficulty unmounting /dev/ from the chroot, apparently necessitating a reboot if I ...read more...

I’m sure there’s already a million “Happy New Year” type posts up but I figured I’d throw in my two cents as well (since I’m actually here for this New Year’s Day).

While I’m at it I’ll pass along some things I managed to accomplish over the past week:

• Have some troubleshooting that you need to do that requires you to have a small partition? (In my case, troubleshooting for bug 118594). You don’t need to re-format your hard drive. Instead (at least on Linux) just create a partition on a file:
  1. Create a small-ish file (for instance, using dd if=/dev/zero of=file-name-here bs=1M count=size-in-megabytes).
  2. From there, you need to create a filesystem on it. I used plain ext2. If you’re not running as root you may need to manually run /sbin/mke2fs file-name-here. (since /sbin is normally only in the PATH for root). mke2fs should complain about the file not being a special block device but you can tell it to proceed. Please note that mke2fs is a horribly horribly destructive thing to do on a live filesystem. ...read more...

2008 has been a great year for me Free Software wise.

Not only did I get the opportunity to attend three awesome KDE developer meetings/sprints, I also got invited and attended the Linux Collaboration Summit.

However, personally the most important aspect of 2008 is me returning to serious KDE development. Hmm, probably not returning since my contributions in the early years more or less where heling other developers, doing a couple of fixes and enhancements, mainly in the KDE Games and KDE Edu areas.

Due to time being available to me only in small chunks of a couple of minutes but all over the day, I moved on to doing support. Both end user support as well as developer mentoring, the latter mostly on web forums such as mrunix (German), qt-forum and I am actually one of the initial guys behind QtCentre.

That was a great time as well as I find helping and receiving many people's thanks extremely gratifying more so when I discovered that people within the KDE community where ...read more...

Quick update: Newly available in Project Neon's kde-nightly is kdeedu . Newly available in the kdebase build is support for Google Gadgets .

First of all… HAPPY NEW YEAR ALL !!

I felt I had to do some research… and I did for couple days till yesterday morning I felt ill as hell. Now, I’m getting better, and it seems the “virus” that hit spain got me too… Anyway, I’m winning the battle to my flu.

So, before getting ill, I had a look at Qt’s signals and slots, and wondered if I could do something similar myself. Well, I called this tiny library “Ideal”, and till now it only has signals/”slots” (there are no slots, we’ll see later) and a small timer for testing purposes…

I don’t mean this thing to be huge, but I guess I will be working on it from time to time. However, it was a great thing for me seeing it working. The “bad” thing: it uses c++0x stuff to work.

Let’s see a small usage example:

#include <object.h>
#include <iostream>

using namespace Ideal;
using namespace Ideal::Core;
using namespace std;

class MyObject
: public Object
{
public:
MyObject(Object *object = ...read more...
