But How Can You Complain When You Do Nothing?
You may have noticed some "bad" data being displayed in the HTML table in the previous installments of this series. Now, we will filter the query to ignore empty documents, and order by Year Arrived and then Year Departed (yearin and yearout)
To do so, replace the previous MongoDB query code:
Template.placesLived.helpers({
places: function () {
return TimeAndSpace.find();
}
});
...with this:
Template.placesLived.helpers({
places: function () {
return TimeAndSpace.find(
{ts_city: {$exists: true, $ne: ""}, ts_state: {$exists: true, $ne: ""}},
{sort: {ts_yearin: 1, ts_yearout: 1}}
);
});
That's Because He was Wearing a Bullet-proof Vest!
Ain't that grand! Here is what the filtered and ordered collection looks like now:
The duplicates are still there; removing one of them is an exercise left to the reader (don't look at me), as is any baroquing or gingerbreading such as adding a map, with a pushpin for each location, perhaps numbered or with some other indication on it, such as certain colors to indicate duration of time spent in that spot, etc.
In the next and final installment of "As the Meteor Blazes", I will provide you with a plethora of poignant points and programatically lucrative links.

I am in the process of morphing from a software developer into a portrayer of Mark Twain. My monologue (or one-man play, entitled "The Adventures of Mark Twain: As Told By Himself" and set in 1896) features Twain giving an overview of his life up till then. The performance includes the relating of interesting experiences and humorous anecdotes from Twain's boyhood and youth, his time as a riverboat pilot, his wild and woolly adventures in the Territory of Nevada and California, and experiences as a writer and world traveler, including recollections of meetings with many of the famous and powerful of the 19th century - royalty, business magnates, fellow authors, as well as intimate glimpses into his home life (his parents, siblings, wife, and children).
Peripatetic and picaresque, I have lived in eight states; specifically, besides my native California (where I was born and where I now again reside) in chronological order: New York, Montana, Alaska, Oklahoma, Wisconsin, Idaho, and Missouri.
I am also a writer of both fiction (for which I use a nom de plume, "Blackbird Crow Raven", as a nod to my Native American heritage - I am "½ Cowboy, ½ Indian") and nonfiction, including a two-volume social and cultural history of the U.S. which covers important events from 1620-2006: http://www.lulu.com/spotlight/blackbirdcraven
