Components and plugins are relatively new features of web2py, and there is some disagreement between developers about what they are and what they should be. Most of the confusion stems from the different uses of these terms in other software projects and from the fact that developers are still wo... |
Each Amazon EC2 instance has associated metadata, as well as user data supplied when launching the instance. The meta and user data is instance-specific, and therefore only accessible to the instance.
The data is useful on several levels, such as configuring SSH public keys, programmatically configuring the instance ac... |
Like in this question, except I want to be able to have querysets that return a mixed body of objects:
>>> Product.objects.all()
[<SimpleProduct: ...>, <OtherProduct: ...>, <BlueProduct: ...>, ...]
I figured out that I can't just set Product.Meta.abstract to true or otherwise just OR together querysets of differing ob... |

What you request cannot be done in Python 2.whatever, for a very specific reason. You want to write:
class Task(model):
title = ''
isDone = False
In Python 2.anything, whatever model may possibly be, this cannot ever allow you to predict any "ordering" for the two fields, because the semantics of a class stat... |
I'm finally settling back into the groove of some of my side projects. I guess I'm handling the new position a bit better as time goes on, and feel that I can spend some free time working on somethings that I want to do, not just things that I feel that I should do.
So, these side projects I do for fun, and they are th... |

The loop works fine until I try to use changeAttributeValues(), and I can change the attribute values outside of the loop, but when I try to put the two together I caus... |

Great answers here! I'm developing a card game using Python and Pygame, which has no double-click support, so I stumbled upon the same problem.
Inspired on Marcel Böttcher's answer, to measure your own time and then double it, I've created a small tool to measure the speed of double-clicks, and I'm sharing with you:
