Narf narf!! Today I fix a bunch of bugs in the undo/redo engine of Dr.Genius. I wonder when this thing will get totally fixed.
It took me the last evening to vote for the Gnome foundation board of director. I've decided to post it there my choices. I don't expect someone will care about that but in one year i will be able to review which people I choose and why.
The people I choose are all but two technicians.
I try to balance the technical ability so the board has an excellent overall knowledge on Gnome. The exception are only Jim, Bart, John but these ones have skill the other don't have. I also try to balance the geographic repartion and get some director from europe. I'm just disappointed we don't get candidate from asia.
Undo/Redo code is progressing smoothly. It now works for creation, deletion, motion, changing item attribute. This is a really nice feature. Also I 've take care to implement a nice way to handle the undo/redo-buttons/menu item, so that other DrGeniusMDI can use the same UI mecanism. When I'll have finished that, I've decided to implement Guile scriptability for the geometric engine, GKO will eventually help on that but well... I'm quite carefull with code contributor now, I've learn a lot with Dr.Genius concerning this topic, it's difficult for people to keep sustained motivation in free software project.
Today I start coding on undo/redo for DrGenius, this will bring lot of side effect as scriptability and even using Corba for a distance manipulation of a figure. At mid-day I stop hacking on that thing and try to work on the AI course. It's incredible how in one sheet of paper they can introduce you 10th of new symbols, 10th of definitions and it tooks you one hour to start to figure out these things. This course can make me feel asleep even on the morning, so i let you imagine after a lunch. Finaly I decide I better hacking on drgenius instead of sleeping...
I'm finaly back from Portugal to Taiwan, the trip was 30
hours long. My soon is very brave to support that!! He is
now running with it's electric car in the appartment, he
can't get sleep, so this gave me the opportunity to write
some diary :)
The last two months in Europe were quite productive, thanks to a nice gift I made to myself before leaving Taiwan: an Acer TravelMate 345T, quite an impressive machine that gave me the opportunity to work on:
Beside that, I was at the LSM event, a very cool non commercial event.
The school will start in one week, it will be paintful to slow down coding but I have decide to implement a database to register and categorize math. exercice, the final goal of the stuff is to allow teacher to build up quickly exercice sheets from exercices in the database. Of course the exercices have to be coded in LaTeX, DrGenius will be very helpfull to design geometric figure in LateX or eps. Oh well this will be a french specific stuff as I'm teaching in a french school. Finally I got a very good excuse to keep coding during this school year :)
Almost finish writing a Latex exporter for Dr Genius figure. All but the text is exported. This is cool so I will be able to produce high quality figure to put on student tests.
At least I finish - almost - to code the new geometric engine. I merge it on the HEAD last night, this was really weird as I need to edit the adminstration file - commitinfo - to get the merge accepted. Apparently a missing .sh extension on the file /cvs/gnome/CVSROOT/check-po-commit block the commit.
Lately, I'm rewriting the geometric engine of Dr Genius. It really needs some clean-up. Also i must credit Ilya Baran for its project Kseg, an interactive geometry free software under KDE. I don't get a chance to try it but looking at the source code, I saw very kind idea that I will use in Dr Genius. Good luck Ilya in your project (http://www.mit.edu/~ibaran). It seems we get very low activity in Dr Genius since one month. I hope my recent commits will remotive the team.
I decide to use GOB, the Geroge Lebl GTK+ builder system, for the Dr Geo MDI child in Dr Genius. So now, all of the MDI child in Dr Genius use the same system, this will make life more easy when it will come to save all in XML. I've also indent the drgeo code to the Gnome style instead of the GNU style.
In France, at the APRIL (french association to promote the GNU philosophy) we are at the point of creating a development group targeted to education. Of course it will use as much as possible Gnome.
Finaly we release Dr Genius 0.5.0, an in the same time Aaron has join us, he will take care of the Plot canvas of Dr Genius, there is already a nice demo of 3D plotting. Now I will work on the save-all-kind-of-data-in-XML feature. Actually multi-figure & multi-macro can be saved in XML.
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.
