Chuck DirectSound error fix

I'm learning dsp and following a tutorial that uses chuck, I install it, try it, and it falls over instantly with this error:

[chuck]: (DirectSound) error (Generic error) creating input buffer (Default Device)!



Solution:

1. Go to Start → Settings → Privacy Settings → Microphone
2. Turn on "Allow apps to access your microphone"

Now you'll never see this error again!

Microphone settings window shows "Allow apps to access your microphone" turned on.

Fix for Jenkins on Mac getting stuck on overnight builds

Every night my dutiful Jenkins build servers build their jobs and every morning I come in to find that a job on OSX has gotten stuck on 'git fetch' all night. The job's console output looks something like this:

[EnvInject] - Loading node environment variables.
Building in workspace /Users/me/Projects/MyProject
[WS-CLEANUP] Deleting project workspace...
[WS-CLEANUP] Deferred wipeout is used...
[WS-CLEANUP] Done
using credential xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Cloning the remote Git repository
Cloning repository ssh://myname@website.org/repo.git
 > /usr/local/bin/git init /Users/me/Projects/MyProject# timeout=10
Fetching upstream changes from ssh://myname@website.org/repo.git
 > /usr/local/bin/git --version # timeout=10
using GIT_ASKPASS to set credentials 
 > /usr/local/bin/git fetch --tags --progress ssh://myname@website.org/repo.git +refs/heads/*:refs/remotes/origin/*

Sometimes it starts again while you're looking at it, as if embarrassed to be caught slacking off all night.

Resolution:

This is because I turn off the display in the evening and the OSX build server server decides to go into sleep mode. Here's how to turn that feature off:

1. Go the the Apple menu, select System Preferences then Energy Saver
2. Check the box that says "Prevent computer from sleeping automatically when the display is off"
