  log4cpp universal dylib on OS X

  Configure and make using GCC 4.0 for x86_64 i386 and ppc against the 10.5 sdk then modify the library using install_name_tool.

  $ ./configure --disable-dependency-tracking
  $ make CC="gcc-4.0 -arch x86_64 -arch i386 -arch ppc7400" CXX="g++ -arch x86_64 -arch i386 -arch ppc7400 -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5"
  
  $ cd src/.libs/
  $ rm liblog4cpp.dylib
  $ cp liblog4cpp.4.0.6.dylib liblog4cpp.dylib
  $ install_name_tool -id @executable_path/liblog4cpp.dylib liblog4cpp.dylib
  

  You may or may not need to modify the library after running make, it depends how the library is bundled with your application.

  Recommendation: z

  z is an awesome bash script that stores a list of your frequently used directories.

  Instead of typing:

  cd ~/Work/ProjectsFolder/ProjectA/Something/Src/
  

  You can type:

  z ProjectA <TAB>
  

  It’s utterly brilliant, check it out on GitHub: http://github.com/rupa/z/

  Thanks to Ben Tappin for the tip.

  Project specific .vimrc / How to modify the python path when working in Vim

  In Vim I often find the need to add my python project to the PYTHONPATH so I can run external tools, code completion etc.

  Try opening a Django project in Vim and importing a model:

  :cd ~/Your/Project/Dir
  :!python
  >>> from yoursite.yourapp import models
  

  You’ll get the following error:

  ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.
  

  Which makes sense, your project source isn’t on the python path. Here’s my solution to applying project specific vim settings / updating the python path:

  Add the following line to your vimrc:

  " Read .vimproj in the working directory
  map <silent> <leader>P :source ./.vimproj<CR>
  

  Then create a file in your project root called .vimproj with the follwing contents:

  " Mysite Specific Vimrc
  
  let $django_dir = getcwd()."/<your django folder name>"
  let $lib_dir = getcwd()."/libs"
  let $site_packages_dir = "/Library/Python/2.6/site-packages/"
  
  if !exists("g:python_dirs_loaded")
  let g:python_dirs_loaded = 1
  let $PYTHONPATH = $django_dir.":".$lib_dir.":".$site_packages_dir
  set path=$django_dir
  set path+=$lib_dir
  set path+=$site_packages_dir
  endif
  
  let $DJANGO_SETTINGS_MODULE = "settings"
  
  echo "Mysite settings loaded"
  

  When I open a project bookmark in NerdTree, I type cd to change the working directory to the project root, then hit ,P to load the project specific settings.

  Recommendation: Inconsolata-dz

  Inconsolata-dz is an excellent programming font, based on Inconsolata, that’s been modified to use straight single and double quotes.
