Qt Crypto Architecture for KDE4?

One of the things I'd hoped to do at aKademy was to get some discussion going about using QCA in Qt4. Unfortunately I had a cold, and spent much too much time sleeping and feeling unmotivated instead. So I thought I'd try to kick off some discussion about it now. I'm also going to post this to kde-core-devel, and that is where the discussion should take place.

Other integration fronts: GNU Classpath

Over on Planet Classpath the people blog about the ongoing
efforts and success with their Qt based AWT peers.

Nice to see that the high quality of Qt's code on all its platforms get more widespread acknowledgement outside the KDE area.

I hate C APIs

Well, not all of them.
Those that create tons of structs for datatypes and even more functions to work with them.
I hate them because they almost look like sane OOP APIs but are awfully to use compared to
what real OOP languages would offer

Consider this example:

void foo()
{
CFStringRef cfstring =
CFStringCreateWithCString(NULL, "http://wwwkde.org/", kCFStringEncodingUTF8);

CFURLRef cfurl = CFURLCreateWithString(NULL, cfstring, NULL);

// use the URL

Progress on an Arthur backend for Poppler

I've had to travel for work, and during a particularly long flight[1], I managed to get stuck into a Qt4 renderer backend for Poppler[2].

I think I'm about a quarter of the way into it - my Arthur[4] backend can render some pretty complex PDF files[8], but the text/font handling is terminally broken, and I'm having good success with some images, but not with others. There are also some things (like patterned/tiled fill) that none of the backends currently appear to do completely, so I'm not sure how important they are. Certainly the next big step is to get the font selection and character positioning sorted out, so typical PDFs will run.

SCI-FI: Better Qt slots and signals with Qt5?

One of interesting proposals published in Technical Report 1, a specification for new functionality being added to C++'s standard library, is the Polymorphic Function Object Wrapper.

Summer coding

We've put together some ideas for Google's Summer of Code. I think there's quite a few interesting entries there and we tried to make sure that there is a nice set of initial ideas. Personally I'd love to see people coming up with their own ideas (which is why I particularaly like the "framework/application addition" entries). If you never ever coded with KDE, don't worry, we'll assign mentors to you who will help you through out your project.

Gradient support for the X server

After the last round of hacking with Zack beginning of April where we speeded up the software fallback for image compositing in the X11 Render extension, I decided to take another round, this time at missing features in X11.

Just having fun

Being a non-meat-eater in Norway is to say the least interesting. It's been a while since I've heard people say things like "oh, you don't eat meat? we got chicken", or "oh, don't worry, we got fish".
I like moving. Change is always fun. I'm slowly learning Norwegian. I was really disappointed though because I missed the Salvador Dali exhibition that was in Philly. If you live somewhere near Philly and have seen it, let me know how was it.
