Taking a bite of the Apple

Giving up the leadership of OGREwas a sad moment for me, but in hindsight it has also been rather liberating. For 10 years I’d spent most of my energy on OGRE or on projects that were related to OGRE. There was an implicit understanding both from the community and from myself that everything I embarked on would in some way tie into OGRE - and indeed my business has always been based on a constant balancing act between how I can make a living while also promoting and advancing OGRE.

Open source is most important to producers rather than consumers

Gartnerhaven’t exactly been the sharpest tools in the box when it comes to predicting open source trends over the last few years, vastly underestimating it until about 2008, by which time it didn’t exactly take a professional analyst to tell you that it was popular. Still, now they’ve woken up to its potential, occasionally they post something useful. In particular, I liked a recent blog post about how open source is “trending towards customer obscurity”- that is to say that while open source is incredibly important to producers of software, the vast majority of consumers don’t really care how their software is made any more than they care how their car was made.

Dependencies to build Git from source on [K]Ubuntu 9.04

Git is picky when it comes to converting large, moderately complex Subversion repositories and so far the only option I’ve found that works reliably is using the very latest version on Linux. Forget about using 1.6.5 on Windows via msysGit, at least for the git-svn conversion it’s very, very unreliable. Similarly I found Git 1.5 on Linux very flaky for the svn conversion. This doesn’t give me the greatest confidence in Git but in order to properly explore all the angles, I’ve committed to making it work even if it means I have to monkey about a bit.

Yay, OgreSpeedTree 2.0b is done

I’ve been pushing quite hard to get this done before I head off to Qt DevDays next week, and luckily it all came together in the last few days: Some of the notable back-of-the-box (if there was a box) items: Upgrade to SpeedTree v5 - supporting all the great new features. See the SpeedTree site for more details on this release. More lighting options - Ambient Occlusion, Ambient Contrast, Specular Lighting, Transmission Lighting, Global Light Scalar, HDR.

Kaz doesn't understand (most) developers

Sony’s PR machine has been rather contrite of late, after some really quite stellar gaffesa few years ago, but comments from Kaz Harai in an interviewrecently are a firm return to the ‘what in Gods name were you thinking?’ school of PR. Ignoring the fanboy-baiting predictions of who’s going to ‘win’ (given the expansions in the game industry, does anyone have to ‘win’?), the bit that got my attention was when he talked about the (many would say unnecessary) complexity of developing for the PS3:

Qt 4.5 will be available under the LGPL

I’m on the Qt(owned by Nokia now) mailing list since I have a commercial license for a client project, and I got a very interesting email today, telling me that on its release in March 2009, Qt 4.5 will be available under the LGPL. This is really big news. Up until the current Qt 4.4, your only licensing optionsare a per-seat and per-platform commercial license (which adds up if you have multiple developers and multiple target platforms, which you will do if you’re using Qt anyway), or alternatively the free option which means you use it under the GPL - meaning all your own code has to also be GPL, with an exceptionthat allows you to publish / use software under other open source licenses too, but nevertheless it all has to be public.
