Operational PGP

This is a guide on how to email securely.

There are many guides on how to install and use PGP to encrypt email. This is not one of them. This is a guide on secure communication using email with PGP encryption. If you are not familiar with PGP, please read another guide first. If you are comfortable using PGP to encrypt and decrypt emails, this guide will raise your security to the next level.

A bijection between numbers and pairs of numbers

Every once in a while I am faced with someone who denies that the rational numbers (or fractions, or pairs of integers) can be put into a bijective correspondence with natural numbers. To deal with the situation, I coded up the bijection. So now I can just say: "Really? Interesting. Please provide a pair of numbers (i,j) which is not enumerated by f, as defined in my gist." I am still waiting for a valid counter-example.

Anyhow, here is a demo of f and g at work. I am using the Python version, but a Haskell variant is included as well.

The 100-th pair is:

>>> f(100)

(10, 4)

Want to pretend an object is a ModelAdmin? Check out the HaystackResultsAdmin
Need to fake a changelist for using in the {% pagination %} template tag? FakeChangeListForPaginator
Need to mount a ModelAdmin for a model that doesn't exist? Make an unmanaged model: HaystackResults
Need to mount a second modeladmin for a model which has already been added? Use a proxy model. I actually don't have an app that does this, as far as I can grep.
Need to change the way the admin looks without replacing a substantial number of the templates? thadminjones
Want frontend editing using the admin to do so? Look upon the terrifying face of [adminlinks](https://github.com/kezabelle/django
