Went for a dive on saturday, around 7pm. Since the river
is toxic at the moment (an algae bloom), we went to the
wreck just off north mole. It seems that all the jellyfish
from the river had gone out to the sea where we were diving.
There were a few stinger jellyfish out there as well. They
were particularly annoying, as you couldn’t really see them
until they were about half a metre from you. I got to try
out my new dive light — it makes a big difference to what
you can see.
Was doing a bit of dia hacking on the weekend as well. I
implemented some convenience interfaces to make writing the
properties routines a bit easier. I also added some code to
help write the load/save routines of an object using the
properties interface. When the properties stuff is done, it
should make writing new objects a bit easier.
I hate the heat at this time of year. I got up to around
40 degrees celcius yesterday.
The properties code in dia is working a bit. I switched
the flowchart box object over to using properties, and it
seems to be working fine. I also added properties code to
the group object. You can select two flowchart boxes, group
them and set both their properties at once. There is still
a bit of work to be done w.r.t. undo with the group object
— I think I will have to implement a composite ObjectChange
to handle that. It will also be necessary to add change
notification to the group properties dialog so that we only
set the properties the user changes (this might be a good
thing in any case).
I will probably add code to make saving an object a one
line operation with the properties code. Loading should be
just/almost as easy. This should make it easier to write
new objects in C. Cyrille is looking at writing some
convenience routines for writing the property set/get
Been working on the property code for dia I proposed a
few months back. This should provide an easy way to
construct the property dialogs for objects. Once I add
support for it in the python scripting plug-in, we should
suddenly have a lot more power in manipulating the diagrams
programatically. One other thing to think about is adding
support for custom properties for custom shapes.
Have been playing around with zope for about a month, and
am very happy with it. Very nice to use and very powerful
(once you grab a few extra zope products and work out how to
Have not posted anything here for a while. I got back
from my holiday last wednesday. It was three weeks in New
Zealand and a few days in Melbourne. Other than getting my
bags lost for two days on the way into NZ, it was a good
trip. In Melbourne, I stopped by at my uncle’s company Data Electronics. Some
of their new products sound very interesting.
One problem with the trip was lack of access to email. I
had heaps when I got back. I quickly learnt that the signs
saying a shop had `Internet/Email’ meant they had a web
browser with its home page set to hotmail. Not very useful
if you need an ssh client. Maybe I should look into one of
those java ssh clients for such occasions.
Matt Wilson has been doing quite a bit of bug fixing on
gnome-python, so we will be making a new release of that
soon. A number of people have been doing some work on dia.
Mainly Cyrille who has been doing some new object libraries
and and a bit of work on other bits. There are also a
number of custom shapes that people have done (mainly
network related ones) that I need to integrate.
I made another release of Dia. This
one should fix the bugs people reported just after the 0.82
release. You can now copy/paste image and bezier objects
without dia crashing. I also added a new export dialog
modeled after gimp’s save dialog. This also allows me to
separate off export filters to plugins, which is good.
I have included a partially complete CGM filter with the
new release. It does everything except beziers at the
moment. There is a polybezier element in CGM v3, but I have
not had much luck finding docs for it. I don’t even know if
it is meant to be a closed, filled region or just a
Some more work on gnorpm. It almost compiles again. I
just need to finish off converting the web find window to
the new API and then I can start testing it. After that I
should see what changes are necessary to get it compiling
with RH6.1 and make sure it doesn’t crash in that setup.
Then I can go and start cleaning out all the bug reports.
Is there any record for the largest number of merged bug
reports closed in one go? It certainly feels like I shoulf
be in the running 🙂
I made my first release of dia as its new maintainer. It
mostly seemed to go well. There are a few bugs that showed
up after the release, so I will have to fix those. I guess
we can get back to breaking things to add new features.
Did not end up going diving on monday night, since it
felt like more work getting everything ready than we wanted
I commited the new GnomePaperSelector widget and
GnomeUnitSpinner widget to gnome-libs HEAD branch. As well
as looking nicer, it should be easier to use for people
using something other than points as the paper units.
Doing a bit more work on the glibwww based rpmfind code
in gnorpm. I think I am getting close to having the find
directory compiling correctly. Then I will have to check if
all my logic is correct and convert the rest of gnorpm
(which would be easier).
I got my uni results yesterday. I got good marks in both
my computing and pure maths majors. I got invitation for
honours year letters from both the maths and computer
science departments. I will have to decide where I want to
do honours. Apparently I got the highest score in the
computer networks unit, which means I will be getting a
prize from a company called AlphaWest.
I converted the page setup widget I wrote for dia to use
GnomePaper and GnomeUnit. After doing a bit more cleanup,
and implementing the old GnomePaperSelector interface, I
will commit it to gnome-libs HEAD branch.
Dia now has a bezier connection line. It is a mixture of
work by Lars Clausen and me. It works fairly well. There
is a patch for it from Lars to better handle the initial
drag when placing the object, but I haven’t got round to
applying it. Cyrille has a few patches to start doing the
properties interface. I haven’t read them yet, and I think
I will wait till 0.82 is out before applying them
I should really do a bit more work on gnome-python and
gnorpm. I should probably spend a while bringing
gnome-python back up to scratch and release a new version.
As for gnorpm, I have got a bit stuck implementing the
dependencies code in terms of glibwww. It is quite
difficult handling the state between callbacks.
Alexander Larsson handed over the job of maintainer of
dia to me. He has done a great job so far, but did not have
enough time to put into maintaining it. I have a few ideas
for new features I want to work on. These include the
scripting interface, object properties and printing
