I have two user accounts set up on my mac. User drew I use for most things, but if I'm making a screencast I'll switch to the demo user. I know that the demo user has a clean desktop, and the font size is larger than usual in my terminal and text editors, making everything a bit more legible when capturing the screen. When I record a screencast as the demo user, I save the file to /Users/Shared/screencasts. As I understand it, the /Users/Shared directory is supposed to be accessible to all user accounts on the mac. If I created and saved a screenflow document as the demo user, I should be able to read and write that file when logged in as user drew.

That was the theory, but it didn't always work out that well in practice. I would occasionally find that a directory was only writable by one user or the other. Perhaps I'd open a screenflow document as user drew and attempt to export the video to the same directory, only to find that the directory was owned by demo, meaning that I couldn't cr

# put this in your .bash_profile

# Piece-by-Piece Explanation:
# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
# the $PROMPT_COMMAND environment variable is executed every time a command is run

Introduction

At DICOM Grid, we recently made the decision to use Haskell for some of our newer projects, mostly small, independent web services. This isn't the first time I've had the opportunity to use Haskell at work - I had previously used Haskell to write tools to automate some processes like generation of documentation for TypeScript code - but this is the first time we will be deploying Haskell code into production.

Over the past few months, I have been working on two Haskell services:

• A reimplementation of an existing socket.io service, previously written for NodeJS using TypeScript.
• A new service, which would interact with third-party components using standard data formats from the medical industry.

I will write here mostly about the first project, since it is a self-contained project which provides a good example of the power of Haskell. Moreover, the proces
