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.

- Re-implemented dependencies, and tested variously. For my test case
performance is indeed O(N) not O(N*N) giving a massive speed increase. Fixed
several rather serious bugs that had gone unnoticed for too long.
- Brothers birthday, this involves getting up during the day.
- It turns out that dependencies were well broken, essentialy instead
of storing the inter-sheets attached to the sheet they applied to, they were
stored in the sheet that had the reference in. Hence when a cell was changed,
in order to see if it was an inter-sheet dependency all the sheets
dependencies had to be traversed horribly wastefully. Of course, changing this
simply removes the burden to cell_drop_dependencies, but this is not called
in the re-calc loop. See add_cell_dep & cell_get_range_dependencies for the gore.
Fixing this might help inter-workbook dependencies get done sometime.

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.
