Small fixes

• The live-coding environment Fluxus did not compile on my Arch box, but it was quick to fix it. Compiling fluxus 0.16rc3 against drscheme 4.2.3 and g++ 4.4.2 goes on as follows:
  1. Grab the latest source fluxus-0.16rc3.tar.gz,
     dive into the directory
     src/fluxus-0.16rc3/libfluxus/src/
     and add the line
     #include <stdio.h>
     to these files:
     • OBJPrimitiveIO.cpp
     • SkinningPrimFunc.cpp
     • SkinWeightsToVertColsPrimFunc.cpp
     • GenSkinWeightsPrimFunc.cpp
     • GLSLShader.cpp
     • PolyPrimitive.cpp
  2. makepkg -e
  3. pacman -U fluxus-0.16rc3-1-i686.pkg.tar.gz
• Easy backup of regular files I have created/modified during last few days. The sample shows how to limit the size and exclude on the hidden files and/or an EXCLUDE pattern.
  
find /home/elf \
  \( ! -regex ".*/$EXCLUDE/.*" \) \
  \( ! -regex '.*/\..*' \) \
  -type f \
  -mtime -$DAYS \
  -size -$SIZE \
  -exec cp {} //media/usbstick/daily-backups/$DAYDIR/ \;

  .. and just in case, a list of those files and their respective and total size
  
find /home/elf \
  \( ! -regex ".*/$EXCLUDE/.*" \) \
  \( ! -regex '.*/\..*' \) \
  -type f \
  -mtime -$DAYS \
  -size -$SIZE \
| tr '\n' '\0' \
| xargs -0 du -ch
