Yesterday I came across a short article in WebUpd8 about this little tool called undistract-me. It will alerts you when long-running commands finally complete.
In ubuntu the installation is as simple as this:
$ sudo add-apt-repository ppa:undistract-me-packagers/daily
$ sudo apt-get update
$ sudo apt-get install undistract-me

It can be a good idea to use some kind of caching. Django provides a robust cache system. It's possible to store and retrieve wide range of data with different level of complexity.
Most easiest ways to use caching is to use:

The question is about having 'now' in blocktrans.
In blocktrans we can't use templatetags so we will assign result of the templatetags to a variable, like this:
{% url "add_account" as add_account_url %}
But 'now' doesn't act the same way.
{% now "Y" as my_date %} will print the year and my_date will be empty.

If you are using PuTTY on Windows you can pass your login credentials in command line. In such way you can create a shortcut and skip the login process.
ssh does not have such command line option, but you can achieve the same effect with few simple steps.

Kari - embeded as base64 :)
Look at the image on the left. It's embedded. The idea is very simple.
Open some image file.
Read it in a string.
Encode it with base64.
Now you can use the result as src in the img tag. This image can be used in html email messages or can be used in the css.
Here is some python code:
png_file = open('applets-screenshooter.png','rb')

Like most people today. They were all dumped in one directory. It was very difficult to view them. So I wrote a very short python script that reads from the EXIF date the photo was taken.
