A while ago, for whatever reason, I couldn’t get my wireless usb card to work on my Raspberry Pi. Well, I finally decided to revisit the issue. Here’s what worked:


First, create a plist file at /Library/LaunchDaemons/org.mongo.mongod.plist:

sudo vi /Library/LaunchDaemons/org.mongo.mongod.plist

Next, copy/paste the following XML into the file (keep in mind, your paths to mongod and the database may differ… adjust accordingly if need be):

If you haven’t yet, create a file for the log and a directory for the database:

sudo touch /var/log/mongodb.log

sudo mkdir /var/lib/mongodb

From the command line, run the following:

sudo chown root:wheel /Library/LaunchDaemons/org.mongo.mongod.plist

sudo launchctl load /Library/LaunchDaemons/org.mongo.mongod.plist

sudo launchctl start org.mongo.mongod

If you get any of the paths wrong in the plist file, resulting in the following error:

launchctl start error: Bad file descriptor

… you will need to unload the plist file and load it again, like so:

sudo launchctl unload /Library/LaunchDaemons/org.mongo.mongod.plist

sudo launchctl load /Library/LaunchDaemons/org.mongo.mongod.plist


From the command line, use the following steps to upgrade Node.js to the latest version using TJ Holowaychuk’s (visionmedia) n module.

From the Readme.md out on GitHub, the “n” module is a:

Simple flavour of node binary management, no subshells, no profile setup, no convoluted api, just simple.

First, clear NPM’s cache:

sudo npm cache clean -f

Next, install the “n” module:

sudo npm install -g n

To upgrade Node.js to the latest version, use:

sudo n stable

To upgrade Node.js to a specific version, use:

sudo n 0.10.32

Check the version:

node -v

v0.10.32
