Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?

A crash course in setting up your Python Reddit bot on Heroku

You'll need to do the following:

• You need to make your bot a python app. Do this by making another directory (can be the same name as the regular one) and put all your python code in that, and make an empty file called __init__.py in it as well. See how I structured mine if this isn't clear. In your base directory, create two files: "requirements.txt" and "runtime.txt". The requirements.txt file should be the output of pip freeze (you can run the command "pip freeze > requirements.txt"). If you're not using virtualenv, you'll need to go through after and delete all the lines with packages your code doesn't actually use. Check out mine to see what I mean. Runtime.txt just specifies with python version for heroku to use. Mine just has the line "python-2.7.4" in it. All of this will tell heroku to recognize your bot as a python app.

/**
 * Creates a 'ghost' bitmap version of the given source drawable (ideally a BitmapDrawable).
 * In the ghost bitmap, the RGB values take on the values from the 'color' argument, while
 * the alpha values are derived from the source's grayscaled RGB values. The effect is that
 * you can see through darker parts of the source bitmap, while lighter parts show up as
 * the given color. The 'invert' argument inverts the computation of alpha values, and looks
 * best when the given color is a dark.
