What is Chariot Day?

No, Chariot Day is not a group of Ben Hur enthusiasts reenacting Roman-era racing.  Chariot Day is a one day technical conference put on by the techies at my company, Chariot Solutions, on a Saturday.  To borrow a phrase, Chariot Day is of the people, by the people, for the people.  It is loose, it … Read More

Groovy Script to Tame Gmail Attachments

I like Gmail but it has a big short coming: you can’t sort mail by attachment size. This means that if you are running out of space in your Gmail account, you can’t easily find large attachments like that 25MB video that your friend sent you of his kid’s graduation or other large attachment that … Read More
