Sixth grade students (ages 11 to 12, roughly) were instructed to imagine that they have no television, computer, or telephone for a week and write an essay (in the form of a letter to their parents) on what they would do with their time and why. The assignment was given under standardized test conditions: 90 minutes with nothing but pencil and pape...

The keyboard shortcut for resizing all columns in a report-mode (also known as Details mode) list view control to fit the current content width is Ctrl+Num+. That's the + key on the numeric keypad. (If you're using Explorer, you can also right-click the column header and choose Size All Columns to Fit.) Note that this command is a verb, not a st...

A colleague posed a little puzzle for a fun little app he was writing in HTML: He wanted to generate a random color. If you search around the intertubes, you can find several possible attempts at a solution, like this collection, and an interesting example that has trouble with the pigeonhole principle.

Anon asks, "How do you come up with new shortcut keys and how do you deal with different keyboard layouts? What is the process; is there a company-wide procedure to keep things consistent?" This is several questions (none of them really a suggestion, but I've given up on making the Suggestion Box about suggestions; now it's just the "Ask Raymond a...

Miral asks for the recommended way of passing messages across processes if they require custom marshaling.
