Drupal: Where's my CCK content get stored in db ?

Posted Tue, 16/06/2009 - 12:10 by kamal

Wrote about internal CCK storage in my personal blog sometimes ago but looking through issues coming up recently in our issue tracker suggest that some of developers here still not sure where their CCK content are stored in the database. Briefly revising this topic to give some clue on where to look after when something goes wrong with our CCK related content.

#geekcamp Malaysia presentation: A Coder's Intro to PostgreSQL+PostGIS

Posted Wed, 10/06/2009 - 19:53 by angch

Gave a quick and dirty talk at #geekcamp Malaysia: A Coder's Intro to PostgreSQL + PostGIS.

This looks like a topic I'd be revisiting and revising as I'm heavily into PostGIS these days, and definitely felt that the I missed several important topics. I'll just put this up here for now, and we'll see how well it improves.

Drupal: Namespace your CCK fields

Posted Wed, 03/06/2009 - 15:34 by kamal

Not aware of this until it was too late. All CCK field was stored in a flat container in table node_field. It's not unique per content type. That means you cannot have two fields with a same name although that field was used in different content type. From the UI, if you create field with a same name, it'll just append an arbitrary number such as _0, _1 to make it unique.

VMware workstation keybindings fix in Ubuntu Intrepid

Posted Fri, 22/05/2009 - 20:22 by angch

Up/down keys, etc are not mapped properly in a machine hosted by Intrepid, when it was okay running under Hardy.

One fix was to .vmware/preferences, add:

hint.xkeymap.notLocal = "FALSE"
xkeymap.nokeycodeMap = true

Forgot where I got the above from. VMware server uses .vmware/config, if I remember correctly. Also VMware will pop up a warning when you start it.

Self Signed Cert, cheat sheet.

Posted Thu, 21/05/2009 - 13:01 by angch

No encrypting ofs erver.key in the first place, so we have one less step. Commands:

openssl genrsa -out server.key 4096
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
cat server.crt server.key > $myserver.pem
Apache config:
SSLEngine on
SSLCertificateFile $myserver.pem
SSLCertificateKeyFile $myserver.pem
nginx config:
ssl  on;
ssl_certificate $myserver.pem;
ssl_certificate_key $myserver.pem;

OpenOffice 3 backports for Ubuntu.

Posted Tue, 19/05/2009 - 11:17 by angch

Caveat: following undergoing testing:

Intrepid:

gpg --keyserver keyserver.ubuntu.com --recv-key 60D11217247D1CFF
sudo -s
echo "deb http://ppa.launchpad.net/openoffice-pkgs/ubuntu intrepid main" > /etc/sources.list.d/openoffice
gpg --armor --export 60D11217247D1CFF | sudo apt-key add
apt-get update
aptitude dist-upgrade
apt-get upgrade or dist-upgrade doesn't seem to resolve the dependencies properly.

Hardy: gpg --keyserver keyserver.ubuntu.com --recv-key 60D11217247D1CFF sudo -s echo "deb http://ppa.launchpad.net/openoffice-pkgs/ubuntu hardy main" >

PHP development server

Posted Wed, 06/05/2009 - 17:02 by kamal

One thing that I like in various Python frameworks such as Django etc, they come with built-in development server that allow you to start developing the application without worrying much about properly setting up apache and all sort of things regarding deployment. Though personally, I'd prefer developer to have some knowledge in configuring apache (at least in their local environment) having some sort of development server still being useful even for myself.
