You got your hands on some data that was leaked from a social network and you want to help the poor people.

Luckily you know a government service to automatically block a list of credit cards.

The service is a little old school though and you have to upload a CSV file in the exact format. The upload fails if the CSV file contains invalid data.

The CSV files should have two columns, Name and Credit Card. Also, it must be named after the following pattern:

YYYYMMDD.csv.

The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

The Learning Haskell guide has been moved to a git repo to enable outside contribution

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

	You appear to be advocating a new:

	[ ] cloud-hosted [ ] locally installable [ ] web-based [ ] browser-based [ ] language-agnostic
	[ ] language-specific IDE. Your IDE will not succeed. Here is why it will not succeed.

	You appear to believe that:
	[ ] Syntax highlighting is what makes programming difficult
	[ ] Garbage collection is free
	[ ] Computers have infinite memory
	[ ] Nobody really needs:
