Developed four years ago by a fast-moving online-news operation, Django was designed to handle two challenges: the intensive deadlines of a newsroom and the stringent requirements of the experienced Web developers who wrote it. It lets you build high-performing, elegant Web applications quickly.

Django on Nginx

Quick Link, prefer Nginx over Apache or Lighty so will want to have it under this from day one.

Bazaar is a Python-based distributed versioning system, really simple lightweight and works under and with pretty much anything.

More here but to get it installed on your mac with macports just run...

sudo port selfupdate
sudo port install bzr

After it's installed and activated tell it who you are so it knows where all these changes are coming from in the future.

bzr whoami "John Doe <john.doe@gmail.com>"

You can check that's worked via

bzr whoami

Which should output who you told it you were,

Putting things under Bazaar

Next up it's real simple to start getting things stored under Bazaar, if you've used things like Mercurial or GIT then this should be a walk in the park,

First off navigate to the project you want to put under it then init a new Bazaar repository.

bzr init

Next up add all the files you want into the repos via,

bzr add .

...this'll add everything in the current directory you're in into the repository

Next up commit your files,

bzr commit -m 'initial code'

Should go smoothly listing all that you've done and give you a revision number (in this case 1).

You can then check the log for what's occured via,

bzr log

Which will show you the history, timestamps, user names & emails and messages posted so you can quickly see how things are evolving; and being Python it's pretty fast.

More here

Like most others, your repository is kept under a hidden system directory .bzr, find it easily with,

ls -a

However unlike others it doesn't mind what you put in it and will pack them tightly so it doesn't consume too much space, plus you can use it against any storage medium, current version at time of writing 1.1

Aptitude or Apt-Get

Was asked this recently, as far as I know the only core difference is Aptitude has a better way of handling dependencies when you remove a package; cleans up better. In all you should try to switch to Aptitude where possible, if you've installed a package with Aptitude then when you remove it via Aptitude it'll know about any dependencies it has to check for or orphaned packages.

Update and Upgrade

apt-get update
apt-get -u upgrade

aptitude update
aptitude safe-upgrade

Install Package

apt-get install gedit
aptitude install gedit

Remove Package (keep config files)

apt-get remove gedit
aptitude remove gedit

Remove Package Completely

apt-get --purge remove gedit
aptitude purge gedit

Upgrade Package

apt-get install gedit

List Possible Upgrades

apt-get upgrade gedit

Show Package Info

dpkg --info gedit*.deb | less

List All Packages

dpkg -l

Check if Package install plus Info

dpkg -l | grep -i 'gedit'

List files owned by package

dpkg -L gedit

List files inside Package

dpkg --contents gedit*.deb

Find out who owns this Package

dpkg -S /bin/netstat

Check if Package installed and it's Status

dpkg -s gedit| grep Status

Show Dependencies for a Package

apt-cache depends mysql-server

Wajig

Wajig is a Linux tool that combines a lot of the abilities within apt-*, aptitude and dpkg into one command. Written in Python it handles normal users and super-user privileges & can be installed with...

apt-get install wajig
aptitude install wajig

Good site to use when planing your next vacation, flack jackets optional.

Built with Python and powered by the PostGreSql database engine it's certainly an advanced webapp, with custom maps built specifically for the job using a number of open-source tools like MapNik & TileCache it's no slowcoach to technology; good work!
