Lazy evaluation hang nail

Jenny Bryan

A group of us at UBC are working through Wickham's Advanced R Programming book together. We just tackled the chapter on Functions, which reminded me of this ...

How to make the Webster's 1913 your default Kindle dictionary

1. Download a Kindle-compatible version of the dictionary here. Unzip the .rar archive.

2. Get the "Send to Kindle" program on your computer. Here's the link for the Mac.

3. Right-click your recently downloaded (unzipped) dictionary file, and click the "Send to Kindle" menu item. It will arrive on your Kindle shortly.

4. Once the dictionary has arrived, go to your settings -- on my newish paperwhite, it's at Home > Settings > Device Options > Language and Dictionaries > Dictionaries > English. Choose the Webster's 1913.
