The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

Feeping creaturism

I've spent the past week or so adding a new feature to The Boston Diaries and I'm finally rolling it out—email notification of updates!

A week for a simple feature might seem like overkill, but I did want to do this right and with as little breakage as possible. And it's not quite as straight forward as you may think either.

Design strategy number one: avoid complaints of spam as much as possible. As a result, I added a verification scheme. Upon first submitting an email address, the program displays a page saying the email address has been collected and at the same time, an email has been sent to the email address requesting verification. This is to keep a malicious person from submitting an email address to some unsuspecting person who then starts receiving emails about some oddball site being updated. So simply adding an email address to the end of a list is right out.

To this end, there are two lists maintained—one list of addresses that I am waiting a reply from, and the second one that actually gets sent the notifications of updates.

When the person subscribing replies, the reply email is sent to a program that gets the email address that doing the replying, and looks it up in the pending list, and if so, removes it from the pending list and adds the email to the notification list, and sends an email saying as much.

The program that processes new entries then goes sequentially through the notification list and sends out an email message.

Fairly straightforward, although there are some details I skimped out on (like checks to see if the address is already in one of the lists, unsubscribing, just small details) that's pretty much how it works. The time spent though, was making sure I got all the details (big and small) right. Oh, and making it such that Spring could use it for her journal as well.

Obligatory Links

Obligatory Miscellaneous

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: http://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

http://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
