This is my (in)activity log. You might like to visit
Productivity a subsidiary of Collabora focusing on LibreOffice support and
services for whom I work.
Also if you have the time to read this sort of stuff you could enlighten
yourself by going to Unraveling Wittgenstein's net or if
you are feeling objectionable perhaps here. Failing that, there are all manner of interesting things to read on
the LibreOffice Planet news
Stuff Michael Meeks is doing
More bootchart2 prodding, generated and dumped the nice
process hierarchy, and started poking at the python to render it.
I have to say that a great, great loathing is growing in me
what you are !). I feel like adding comments before each method of the form:
And of course just that simple example took me sixty seconds
to unwind: dig back to each constructor to be sure.
# CairoContext, Process, ProcessTree, float, float, Tuple(x,y,w,h), Tuple(x,y,w,h)
def draw_processes_recursively(ctx, proc, proc_tree, y, proc_h, rect, clip) :
Feeling good about yourself ? time to start using
VBA, or it's moral equivalent: python, for a while. You could argue
that the way to fix this is to impose 'self discipline' (similar
to the just-a-sub-set-of-C++ argument) - and either mangled
the type into all your variable names (but I am not Hungarian), -or-
to try to use the same variable name everywhere for a given type
(until you have two in the same method).
Python: it scales to two whole screen-full of code
without loosing readability! Python: why write code to be read,
when it's so easy to write it new ? Python: great if you can hold
the whole program in your head. Now if only Google could target
... we might have a readable language, with an incrdibly
heavy-to-start run-time (hmm).
My next bug-bear was return values. Isn't it magic to have
a function call that may not return a value, yet gives no
warning (somehow I lost the ultimate 'return' statement in a
sub-method - perhaps it still lurks, nicely indented, somewhere
else in my code):
Nice; I spent half an hour finding the missing return.
As a helpful reminder, here is what a real language would say:
# some code, conditions, forget to return ...
a = doit()
if a: # is not None
# do something.
doit.c:8: warning: control reaches end of non-void function
Eventually (by crawling) arrived at the goal of beautiful
rendering, despite loosing both feet in the process.
Dinner, and put the babes to bed, while J. went out to
counsel a new client. Prodded at the reprap. After re-working
and tightening the X axis yesterday; I turned up the Y axis
power (being right on the edge is not so good), for the Z axis
tweaked the gear teeth, tightened the belts, applied mini (DRAM)
heat sinks to various chips, and ... got my first real, complete
print-out, of a coat-hook; generated by repsnapper (nice); fast
Printed out a beer
bottle opener, and had an Alsterwasser to celebrate (after mangling it
a little by omitting to insert a suitable one cent coin). Apparently
rep-straps are sufficiently easy to build that any old idiot can do it.
Drawings of ply-wood, and openSUSE packages to follow.
It seems that repsnapper's optimistic approach of dead
reckoning without ever resetting to the end-stops works rather well,
and faster too. Surely it is somewhat amazing that the machine can
get tens of 0.4mm layers on top of each other reasonably precisely
with those means.
