Setting up Python/Pylab environment on machine with no root access

No pip? Bootstrapping ourselves 
cd /tmp (We have write access here)
curl -O https://pypi.python.org/packages/source/p/pip/pip-1.3.tar.gz
tar -xzf pip-1.3.tar.gz
cd pip-1.3/
python setup.py install --user
Python informs us pip is now installed under 
~/.local/
cd back to our directory. Add this path to .bash_profile 
PATH=$PATH:$HOME/.local/bin
Let's try this out: 
pip install matplotlib --user
pip install ipython --user
pip install --upgrade nose --user (The server had an older version of nose)

However there is a lot of fine print to the __del__ method. A cleaner way of doing tear-downs is through Python's context manager , manifested as the with keyword. class CrushMe: def __init__(self): self.f = open('test.txt', 'w') def foo(self, a, b): self.f.write(str(a - b)) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.f.close() return True with CrushMe() as c: c.foo(2, 3) One thing that is important, and that got me just now, is error handling. I made the mistake of ignoring all those 'junk' arguments ( exc_type, exc_val, exc_tb ). I just skimmed the docs and what popped out is that you need to return True or

Using adminer on Mac OS X

adminer is a nice php based sqlite manager. I prefer the firefox plugin "sqlite manager" but it currently has a strange issue with FF5 that basically makes it unworkable, so I was looking for an alternative to tide me over. I really don't want apache running all the time on my computer and don't want people browsing to my computer, so what I needed to do was: Download the adminer php script into /Library/WebServer/Documents/ Change /etc/apache2/httpd.conf to allow running of php scripts (uncomment the line that begins: LoadModule php5_module Start the apache server: sudo apachectl -k start Operate the script by going to localhost Stop the server: sudo apachectl -k stop
