Tornado firing vs yielding

Yielding a list of tasks in Tornado 4.0

Note: This behavior has changed in Tornado 4.1

Executing python will produce results similar to:

$ python
one is sleeping
two is sleeping

Python: variable scope

Python's scope

Python's scope of variables should be intuitive, but for those that don't find it as such here's a quick example.

In the file below I create a dummy class Temp() which prints some debug text when its created and destroyed.

$ python
Initiating quick
Destroying quick

Automatic Github changelog

Doing a proper version release requires documenting all the things you've changed. Frequently is used for these purposes.

Unless you are maintaining that file throughout the changes it can become a hassle. Luckily you can leverage GitHub's issue tracking and PR system to manage that for you. If you use GitHub's milestones like you would versions then you have all the data there for you. However, you're stil left with the collection and formatting of the changes.

The script below automatically grabs that data for you and creates a markdown output. I've been successfully using it for our Kingpin project for several releases. Here's the sample use:

$ ./get_changelog Nextdoor/kingpin 0.2.0
## Version 0.2.0
 * #174: Add actor 'initialization context' support. ([@diranged])

Working with forks, branches, and pull requests

Helper scripts for git

When working with forks & branches for features and pull requests I often find myself needing common actions, like

  1. Create a new branch, and I don't care what it's named
  2. Update the last commit, and keep the commit message
  3. List all the branches I have with some description of what that branch is

Below are the scripts to do just that.

Quick handling of python's virtualenv

The two functions (akt and mkvin) in this gist allow for a quick way to create end activate python's virtual environments

mkvin will create a new virtual environment in $HOME/virtualenvironments directory with the name of the directory you're in.

For example:

[mikhail@MadRussian git]$ mkdir projectzero
[mikhail@MadRussian git]$ cd projectzero
[mikhail@MadRussian projectzero]$ mkvin
