Perl Catalyst and DBIx::Class from Joshua Drake on Vimeo.

Matt comes to blows with the slideshow in above talk so you may prefer to watch a shortened version of this talk from the London Perl Workshop November 2008.

The slides can be found on Shadowcat’s website (requires Firefox).

More Perl videos are available though this tag does mix in some non related stuff but you can watch Giles Bowkett attempt:

Lightbulb Joke: Perl from giles goat boy on Vimeo.

or instead watch something that is really funny:

YAPC::EU Promo from Curtis Poe on Vimeo.

PS. I did try embedded the vimeo videos in post but WordPress decided to spit them out and just leave the placeholders ;-(

PPS. Now fixed! Use (vimeo ####) where #### is the video id from the vimeo URL and replace parenthesis with square brackets!

A good place to start is an article on Apple’s developers site…. Postgres on Mac OS X

However I’ll be using DarwinPorts (or MacPorts as its now known) instead of fink. In fact you may ask why don’t I just install the Darwin port of Postgres? When it comes to critical apps which are important to me I always prefer to use the source and therefore can apply any compilation settings that I may need.

Here’s the steps I went thru (via Terminal session). DarwinPorts being installed is a prerequisite….

First off u must become root. You can do this from an admin account with just “sudo -s“.

Next we must install some ports that Postgres will need….

    port install readline
    port install gmake
    port install bison


Then we need to create a /usr/local directory (mkdir /usr/local). Within this we need a “src” directory where we can download the Postgres source code to (cd /usr/local ; mkdir src ; cd src).

Download the latest stable PostgreSQL source from www.postgresql.org and unpack it…. gzcat postgres-source.tar.gz | tar xvf -

Now you in a position to compile the source code. Go into the Postgres directory that was unpacked and do the following steps….

    ./configure --with-includes=/opt/local/include/ --with-libraries=/opt/local/lib --with-bonjour
    gmake
    gmake install


PostgreSQL as now been compiled and installed. Next step is to initiate the database storage area. For this you will need to create a “postgres” account on your Mac. (If unclear then read instructions in the article on how to do this). Then do this…..

    mkdir /usr/local/pgsql/data
    chown postgres /usr/local/pgsql/data
    su -l postgres
    /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data


We now have a fully working PostgreSQL RDBMS on your Mac.

Next you want to put the following in your login .profile (for the postgres account)….


    export PGDATA=/usr/local/pgsql/data
    export PATH=$PATH:/usr/local/pgsql/bin


If you now source this profile with you now have the Postgres commands in your $PATH ( . .profile ).

To start the Postgres DB server (postmaster) in the background….


    pg_ctl -l logfile start


and to stop it…..


    pg_ctl stop


You can now go ahead and create a database in PostgreSQL.

That’s it for now but will touch on security & auto launching at later date.
