When optimizing memory access, and memory cache misses in particular, there are surprisingly few tools to help you. valgrind’s cachegrind tool is the closest one I’ve found. It gives you a lot of information on cache misses, but not necessarily in the form you need it.

Just force overwrites on the installation of the conflictive package:

sudo dpkg --force-overwrite -i /var/cache/apt/archives/libqt5multimediaquick-p5_5.0.1-0ubuntu1_i386.deb

If that's not enough for the installation to succeed, you can also force everything dpkg can complain about (be careful doing this!):

sudo dpkg --force-all -i /var/cache/apt/archives/libqt5multimediaquick-p5_5.0.1-0ubuntu1_i386.deb

After doing that, just issue the suggested command again:

sudo apt-get -f install

How to define functions into your makefiles

Minimalish assembly TCP HTTP server program for i386 Linux. It

    .equiv port_number, 8086

Gloriously filthy: defines only two subroutines; all variables are

global. Depends on the C libraries. 3152 bytes of executable

with dietlibc, stripped; only 1000 bytes of that is this code.
