Quantifies the memory optimizations of Redis 2.2, and memory costs of zsets versus sets.
"""
Copyright Michael Parker 2011.
Program to quantify the memory usage of:
a. The compact hash and set implementations in Redis 2.2 described at
http://redis.io/topics/memory-optimization and
http://redis.io/presentation/Pnoordhuis_whats_new_in_2_2.pdf versus their
counterparts that do not contain integers. For the comparisons to be
meaningful, be sure to have hash-max-zipmap-entries and
set-max-intset-entries present in your redis.conf file.

Django test suite problem

Hi all,

I'm having trouble creating a test suite in Django 1.3.

Say I have an installed app in a directory called app_name. One of the files in that directory is foo.py which defines a class named Foo. I want to test that, so I also have a file that directory called foo_test.py which defines a class named FooTest. That file looks like:

import unittest
import foo

class FooTest(unittest.TestCase):

Custom activity to choose a contact with a phone number. But normally you just want new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI).
package com.example;
import java.io.IOException;
import java.io.InputStream;
import android.app.Activity;
import android.content.ContentUris;
import android.content.Intent;
import android.database.Cursor;
import android.graphics.Bitmap;

/**
A UIAlertView that owns its delegate so that the client that displays the UIAlertView
does not need to own it.
This is useful when the client that displays the UIAlertView is not the UIAlertDelegate
implementation. It is free to initialize an object to serve as the delegate that exists
only for the lifetime of the UIAlertView, thereby fostering decomposition.
