Stuff Michael Meeks is doing

This is my (in)activity log. You might like to visit
Collabora
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
feed.

Up early, poked mail, packaging, massaging spec files, and
fiddling with performance at some length left and right, and centre.
Watched brickies finish the wall to the height they could - more
scaffolding arriving tomorrow.
-
Poked at hal; for some reason it is inordinately slow to
start - fired up valgrind; missing ioctl - bother, got the latest
valgrind; eventually unwound the
--retain-privileges
needed to be able to write the output. Compared fdi files vs. moblin:
| OpenSUSE | Moblin |
| .fdi | 1.6Mb | 388k |
| mmap cache | 1.3Mb | 235k |
Interesting - 223k calls to handle_match, yet only
9k 'match' rules in the .fdi files. Of course, during boot this
drags out to a much longer time doing this and that.
-
Fired up a profile of hal startup; 70% of the time
taken in resolve_udi_prop_path, of that 13% in g_strsplit and
g_strfreev and another 50% in strncpy - which it seems can't be
easily in-lined due to the way it's done - how odd. Knocked up
a trivial patch
to ~tripple the speed. 1.8billion pseudo-ops down to 0.64bn.
No doubt there is some obvious silly in my patch, but - looks
good; Kay kindly helped out testing it.
-
Staying up late means the next day arrives without an
interruption in the flow of work ...

themselves, in context, in the battle for ideas, and I love fixes /
improvements / corrections by private mail.
In case it's not painfully obvious: the reflections reflected here are my
own; mine, all mine ! and don't reflect the views of Collabora, SUSE,

It's also important to realise that I'm not in on the Swedish Conspiracy.
Occasionally people ask for formal photos for conferences
or fun.
