so what i did was read the bug report


http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=648278
i tried this so let us see what happens with the next attempt to upgrade
Rashi:/home/mlaks# mktexlsr /usr/share/texmf
mktexlsr: Updating /var/lib/texmf/ls-R-TEXMFMAIN...
mktexlsr: Done.
Rashi:/home/mlaks#

This did not help:

then see the remark there about installing all the texlive-base dependencies
at the same time

Thank you, I found the reason - both bug reports seem to point to the
same problem. It does not show up when all dependencies of texlive-base
are installed in the same aptitude or dpkg run, only when they are
configured first and texlive-base is unpacked afterwards.

And of course it is in my new libpaper'ing code...

A fix is in svn, I'll upload soon.

-----------
that fixes it


so I did this

apt-get remove --purge texlive-base texlive-common texlive-binaries texlive-doc-base tex-common luatex

(copied down all the stuff being purged and then did)


apt-get install texlive-base texlive-common texlive-binaries texlive-doc-base tex-common luatex

and then we were ok

next step is to reinstall whole batch of files that were removed
:)

How to get rid of all the rc entries in dpkg -l?

i just did the following and it seems to work

dpkg -l|grep -e ^rc|perl -pe 's/rc\s+(\S+)\s+\d.*/$1/'|xargs apt-get -y remove --purge

use at your own risk!

windws focus follows mouse registry hacks

inportant information i keep losing.

http://sinewalker.wordpress.com/2010/03/10/ms-windows-focus-follows-mouse-registry-hacks/

1. Run regedit (Win+R, regedit, OK)
2. Open up the key HKEY_CURRENT_USER\Control Panel\Mouse
3. Change the value of the REG_DWORD ActiveWindowTracking to 0×0000001 (1)

4. Open up the key HKEY_CURRENT_USER\Control Panel\Desktop
5. Add 1 to the MSB (most significant byte) of the REG_BINARY UserPreferencesMask. That is, if the current value is 00 3e 03 80 12 00 00 00, then change it to 01 3e 03 80 12 00 00 00. If you used the GUI as above, the MSB will be 41 (which brings the focused window to the front as well), so change it back to 01.


6. To make the focus a little slower, so that pop-up windows are useable, you also want to change the focus timing. Change the REG_DWORD ActiveWindTrkTimeout (also in HKEY_CURRENT_USER\Control Panel\Desktop) to the number of milliseconds to wait before focus shifts to the window under the mouse. I like a value of 0×00000080 (128ms). You might like 200ms (c8), or some faster or slower value.

So, in summary, the Registry keys are as follows for X11-like window focus:

HKEY_CURRENT_USERS\Control Panel\Mouse
REG_DWORD ActiveWindowTracking = 0x00000001 (1)

HKEY_CURRENT_USERS\Control Panel\Desktop
REG_DWORD ActiveWindTrkTimeout = 0x00000080 (128)
REG_BINARY UserPreferencesMask = 01 .. .. .. .. .. .. .. ..

letting a remote machine know about urxvt-unicode terminal

REMOTE=remotesystem.domain

infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"

works nicely if you cant install urxvt there.

see man for urxvt
