Days are arranged into columns by week, then grouped by month and years. Colors by Cynthia Brewer. Layout inspired by Rick Wicklin and Robert Allison. Dow Jones historical data copyright Yahoo!

After some investigation, I realized that Yosemite is using Ruby 2.0 and the bundle here needed Ruby 1.8. | |
I use RVM to manage my Ruby virtual enviroments, and already had added a Ruby 1.8 into my collection. | |
(Look at the RVM docs to see how.) So the shell command: | |

2015-01-14 - Troubleshooting Cron on EC2
Today I had trouble getting a cron job to work.
The cron command was:
# run the lunchbot every weekday at 12:30 pm
30 12 * * 1-5 /home/ubuntu/bothouse/lunchbot/cron.sh > /home/ubuntu/bothouse/lunchbot/cron.log
The first problem, I discovered, was that cron.sh didn't have permissions set to be executable by the user (ubuntu).

While marrying the Neopixel Matrix to a spark.io Sheild Shield, I couldn't seem to get the matrix to respond.
Through testing with other Arduinos (worked), I tried it un-married and with the data pin coming from digital pin 2 instead of the hardwired digital pin 6 -- and it worked.
I don't know if I have a bum Shield Shield or if there's something in its hardware that doesn't play well with pin 6. In the end, I physically trimmed the #6 header pin off the matrix and wired pin 2 to pin 6.
Details of the project that lead to this issue are on johnkeefe.net

From what I understand, one should use this method only if you're running an existing version of GPG Tools that you trust. Here are the steps I took:
- Went to https://gpgtools.org/ and downloaded the latest version
- Clicked on the link for the "please download and import our updated key"
- Got a big screen of scramble, and copied the URL from the browser window
- In Terminal, I used that URL to import the key:
