Disclaimer: I have no desire to re-ignite KHTML vs WebKit arguments. Rather, the purpose of this blog post is to hopefully enlighten a technical question. Over the last few months I've heard many KDE developers in various forums bemoan the lack of a working and stable WebKit KPart. Read More

In my last blog I found out that Qt is being evil when using QPainter::eraseRect() with a QImage based textured brush. How evil? Well, calling QPainter::fillRect() with the same brush results in something like a 30-50% speedup while achieving the exact same results. Read More

Funny little story... I was profiling with valgrind recently and was shocked to discover a huge hiccup in the painting performance of my QImage raster based app. There was this repeated call to QPainter::drawTiledPixmap() that was soaking up CPU cycles. Read More

My previous post touched on the horrid FPS you can expect from any graphics intensive Qt app on the N810 at the moment. Ariya has pointed out one reason for the bad numbers: Qt decides to convert all 16 bit pixmaps to 32 bit before blitting even if the source QPaintDevice and the destination QPaintDevice are both 16 bit. Read More

blah blah blah who took away the delete function for kdedevelopers.org blog entries blah blah blah

With all the recent interest in Nokia's N810 device among KDE and Qt developers I think it is important to note that Qt/X11 painting performance is badly broken when running under Hildon. Read More

The United States just took a gigantic step away from the cliff today. An unknown federal district court judge just told the President of the United States where he could shove his warrantless wiretapping program. Read More

In the recent KDevelop dot interview I noticed a very astute comment by someone named borker: "One of the things I've loved about picking up Qt/KDE was how quickly you can make non-trivial applications, but I found learning Qt/KDE was a weird reverse. Read More

With the release of Trolltech's java bindings it kinda feels like Christmas. I wanted to point out some more presents under the tree... Look closely at the dockwidgets on the right of the image. Read More

Seele, I understand that you are a big Pittsburgh fan and are understandably happy they "won", but I can't imagine how you can call it a "great game to watch." See, unlike most of the country and unlike most of the people at the stadium in Detroit and unlike all of the referees on the field, I was hoping for a Seahawks win. Read More

People who know me understand that I'm a big fan of LLVM. Well, big news... Apple has hired the main developer and is now urging LLVM to be integrated as an alternative backend of the GCC compiler suite. Read More

I have been busy working on Datakiosk and am nearing a new release. I know many folks are a bit puzzled by this application, so to dispel the wonder I have cooked up a pretty cool demonstration of Datakiosk thanks to Klik. Read More

Into hell. That is where I went this weekend. Those of you who've been around me a little bit understand that I suffer from migraines. A lot. Well, yesterday I suffered like I've never suffered before. Read More

Ariya sent an email to the KOffice list today passing along this link to an interview with the program lead for MS Office 12's new UI. All I can say is WOW. Read More

public int hashCode() { /* This is probably a fairly bad hash function */ return 0; }

First, it was just for shits and giggles folks. Don't take it so seriously ;) That said, quite a few folks wonder why I set 'restrict=linux' and not 'restrict=kde' or some such thing. Read More

I was playing with googlefight today when it occurred to me to run a few KDE names through the gauntlet... Amused, I decided to use Google's web API to run the list of kde-ev member names and produce the first KDE-Google-Fight-Royal-Rumble :=) Read More

Like many software developers I am a lazy person by nature. There is a theory which states that the primary motivation which drives software developers to work so hard is in fact, laziness. Read More

dataKiosk: It has been a busy week and with the release of dataKiosk 0.7 now completed I'm glad to see it is getting a little publicity on the dot. It is nice to know that others appreciate your work :) The state of the application is pretty good at this point. Read More

As I said below, I just assumed maintainership of Kugar from adymo and have been working on re-integrating his local tree into koffice svn. Well, that is now complete, although there is still a whole lot of work to be done: d-pointifying the library, getting rid of the Qt-only shell, etc, etc. Read More

I've been following Ashley and Richard's conversations about the new Smoke proposal for KDE4 and I have to say it all reminds me exactly why I have grown to loathe bindings. Read More

I am 2 parts intrigued, 3 parts baffled, and 5 parts just plain gobsmacked by the breaking news that Apple will be switching to Intel processors. The times, they are a chang'in! Read More

Hey, ruurd, I was going to post this as a comment, but blogger's login crap was giving me problems. Anyway, I have several data aware KDE widgets in DataKiosk I hope to introduce into KDElibs with KDE4. Read More

I just released v. 0.6 of dataKiosk. The major changes include editing support via a new configurable form. It also has some handy new editor widgets that are factory created depending upon the field's type. Read More

A couple of updates on the code completion changes. In current CVS code completion can: Complete in TRY/CATCH blocks... Complete on vars declared in if/for/while... Lots of other fixes... And I have this working although the patch is up for review and not in cvs: There are a few issues, because it relies on richtext and the problem is I have to strip out some chars programmatically which becomes a problem for apps who use katepart and completion entries with legitimate richtext chars. Read More

Please, raise your hand if you'd like: Color syntax highlighting in KDevelop's code completion? Icons in the entry list corresponding to the entry type ... ctor, dtor, method, member, etc, etc? Read More

Matt and I are doing a little retouch of KDevelop's code completion. First, on Sunday, Matt made a change which prompts KDevelop to complete much more often than in the past. Read More

There are few certainties in life (death/taxes) and less in software, but if I were to nominate two they would be: MDI is here to stay. Some will always hate MDI. Read More

Brad Hards brings up a twist to the whole kpdf, "to DRM or not to DRM?" question. Would kpdf infringe Adobe's copyright on the pdf spec if they did not include "reasonable efforts" at implementing DRM? Read More

Presenting KDE as an exhibitor at LWE is an interesting experience. I've learned a couple tricks that make things more interesting, both for me and for booth visitors: Keep the screens moving. Read More

DataKiosk is a JuK-like database interface tool for generic SQL databases. What does that mean? Essentially, DataKiosk provides a series of wizards (anyone familiar with Qt Designer's database wizards will find them familiar) that allow you to build a custom Juk-like interface for any SQL database with a QtSQL driver. Read More

By now everyone has heard of Sun's foray into Open Source Solaris. Groklaw has an interesting run down of the incompatibilities between the CDDL and the GPL. I find the whole thing tremendously interesting, but when you really think about it and the possible implications for Linux, it is not all that exciting. Read More

So, I've been working on some kdevelop language support C# for the past few days. I already have some pretty interesting screenshots, but I recently discovered that KDevelop is going through a major change in the way it handles different build systems. Read More

I just added features regarding the C# bindings to the 3.4 feature list. As 95% of the major work towards the new super spiffy Qt# bindings is done, I figured it was time to set some goals for getting all of this in shape for a KDE release. Read More

Just came across this article via msdn, C++: The Most Powerful Language for .NET Framework Programming. Microsoft seems especially pleased with their new version of Managed C++. They've done a complete revamp of their previous . Read More

It seems Trolltech is continuing to wrestle with the problem of pesky developers clamoring for bytecode based (read: higher level) languages. I talked with him quite a bit about this at the recent LinuxWorld in New York, so I know it is on his mind. Read More
