When working with Git, there are two prevailing workflows are Git workflow and feature branches. IMHO, being more of a subscriber to continuous integration, I feel that the feature branch workflow is better suited, and the focus of this article.
If you are new to Git and Git-workflows, I suggest reading the atlassian.com Git Workflow article in addition to this as there is more detail there than presented here.
I admit, using Bash in the command line with the standard configuration leaves a bit to be desired when it comes to awareness of state. A tool that I suggest using follows these instructions on setting up GIT Bash autocompletion. This tool will assist you to better visualize the state of a branc

IE9, IE10, and IE11 don't properly scale SVG files added with img tags when viewBox, width and height attributes are specified. View this codepen on the different browsers.
Image heights will not scale when the images are inside containers narrower than image widths. This can be resolved in 2 ways.
As per this answer on Stackoverflow, the issue can be resolved by removing just the width and height attributes.

The difference between XYZ and TMS tiles and how to convert between them
Lots of tile-based maps use either the XYZ or TMS scheme. These are the maps that have tiles
ending in /0/0/0.png or something. Sometimes if it's a script, it'll look like
&z=0&y=0&x=0 instead. Anyway, these are usually maps in Spherical Mercator.
Good examples are OpenStreetMap, Google Maps, MapBox, MapQuest, etc. Lots of maps.
Most of those are in XYZ. The best documentation for that is slippy map tilenames on the OSM Wiki, and Klokan's Tiles a la Google.

I am no Virgil, but having stumbled my way through Python packaging a few times already, I'm documenting the things I learn as I go here.
To help me learn, I took a survey of the top 15 Python packages on Github along with 12 other commonly referenced packages. I thought... if there are any best
