Custom Django filters are an awesome thing. One downside however is they don't easily allow multiple arguments passed through. I am finding in my time with Django I am wanting multiple arguments more and more. For example, lets look at the simple replace filter below.

Django Decorator to Print SQL Queries

Django's ORM is great for fast development, but it is sometimes all too easy to write inefficient queries in the language. There are a few options to help find rogue queries sucking all that process time. My favorite is of course Django Debug Toolbar. However, sometimes this is not a viable option, such as when writing AJAX processors, or for some reason DDTB is not available to you.

This simple decorator may help you alleviate some pain. It also becomes a useful tool to copy and paste the queries into an external query browser. My favorite for Linux is CrunchyFrog.

Dns, Vps

Being a fan and veteran of both DNS services and I was always very slightly annoyed that I could not do this with my personal domain name. The annoyance went up a little more when DynDNS started forcing me to log in every 3 months just to let them know I am still alive.

Since moving to Linode this weekend, I setup my own short DNS updating script. Update the variables APIKEY, DOMAIN, and RECORD to your desired settings and let her rip. Here are my settings for reference. This way when I hit, it routes to my home network.

  • Update and Install Common Packages
  • Setup Postfix for Email Forwarding
  • Install Basic Apache2 Configuration
  • Install Basic PHP5 Libraries
