Christmas holidays are here! And fortunatley I managed to get a large amount of shopping done on Monday, leaving lots of time for coding. XClient now works pretty well in Linux; interleaved arrays + glDrawElements is working, and all the core stuff seems to be behaving. Furthermore I found the courage to autoconf/make the whole thing, there are several hacks unitl I understand autoconf properly but it does build. And most importantly, the X11 native calls have been replaced with SDL, so Mac or Be ports are now possible.

As regards Constellation, the design and basic framework coding progresses; I really need a working persistence layer so I'm going to hack one up over the next few days ... probably not a perfect solution but a reasonable one. I love the CORBA Name service; if the Notififcation service works as well I will be delighted. So I think I'm on target to have multiple client connecting by January.

Coursework is taking up far too much of my time, fortunatley it'll all be over (one way or another) by Friday. I've been sorting out flights and a pass for the GDC in March, should be fun.

In WorldForge land I wrote up a walk-through of LEMon, MELon and Pegasus in action, and sent it off to John (Sheets) for review; after a bit of replying and re-replying I feel like we're making good progress on getting a usable API without too much delay. I still want much more participation from the other developers ... hopefully we shake some loose.

XClient is being funny: the broken console seems to be caused by something far away from my GL hacking; I suspect it really is related somehow, but I need to crawl through bits of image loading code and see what's going on.

And in Constellation land my CORBA name service stuff has mgaically started working, and I've started building POAs for entities and agents ... I'm still finalising the whole activator / factory / persistence model for entities, hopefully some UML to follow soon on the CNX website.

Saw the Halo demo, and now I really want good trans- and sub- orbital dyanmics models ... lots of problems but so much fun. Get me a dropship !

Spent a few more hours debugging the GL renderer for XClient; I'm getting INVALID_OPERATION errors in weird places (from glEnd). The 3D projection code is behaving itself I think, and the fonts are rendering okay; the console image is still messed up. Once the console is back, I will have equivalent functionality to the old code, so I'll check the new version in, and then start getting meshes displayed.

The CORBA startup code for Constellation is being annoying; I've got reference counting issues somewhere, because all my NamingContexts are mis-behaving. So for now I'm ignoring naming and just getting the server class sketched out. I have a reasonable implementation for tasks, thanks to STL::priority_queue.

Using an STL map to implement FindEntity right now; the long-term solution is probably using the entity POA's AOM instead, and letting CORBA activation do it's magic.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
