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.

Tumbling through Code

I'm still working on the tumbler code and it's more interesting (read: complicated) than I originally thought. Basically, I think I want too much here.

I already parse Bible notations and to that I want to add a date-based reference system for the journal here. The bible notation is of the form:

book `.' chapter `:' verse

while the date based version is:

year `/' month `/' day `.' entry

It's easy enough to specify multiple unit separators, but I do want to maintain a canonical form for the search engines—I'd rather not pollute them with multiple references to the same page, so if someone were to request Genesis.1.1 (note the period instead of a colon), they would be redirected (via a permanent redirection) to Genesis.1:1 (note the colon). Similar for the date tumblers.

So now, while I can accept multiple unit separators, I need to keep track of which are the prefered ones, and which aren't, and do redirection accordingly. Doing this without making the code a horrendous mess is not easy.

Then there is the spelling correction (at least as far as the Electric King James goes)—someone can still have a correctly formatted reference to a book, say Eklesiastics.1:3 and yet it isn't correct. It's not E-K-L-E-S-I-A-S-T-I-C-S, it's E-C-C-L-E-S-I-A-S-T-E-S (don't worry, I can't spell either). In that case, I can detect what the user was most likely trying to get to and again, send a redirection to Ecclesiastes.1:3. But that's something else I need to keep track of.

Eight versions of the tumbler code later, I think I have it working, but I decide to ask for a second opinion. So I ask Mark how he would do it.

“A single unit separator, and if a user specified the wrong unit specifier, it's an error that is reported back to the user,” he said.

“What type of error? 404? Technically it's not found,” I said.

“Maybe not a 404, but an error page should come back, possibly saying `This is how you need to form the request,' ” he said.

“I hate programs like that, Mark. They can detect the error, they can even correct for the error yet they don't.”

“I'm for strict parsing rules and if they're not correct, it's an error.”

In once sense, his way is easier for the programmer—it's this format or it's an error. The code is eaiser to write and possibly maintain but it makes more work for the user. My way is harder to write, get correct and possibly maintain but is more forgiving of human input error and tries to do the Right Thing.

Coincidently, Mark doesn't like computers that attempt to do The Right Thing. Can't say I blame him much—many programs that attempt to do The Right Thing fail miserably all around. And he does have a point in that my tumbler code may be trying too hard to be general use, what with flags being passed back and forth.

Which explains the eight versions of code.

I think I finally have it though.

“Feng shui, baby. Feng shui,” said the gratefully dead paper millionaire

Mark and I were suckered into helping our friend John unload his truck of music equipment and move some furniture in his house.

For the record, John is a paper millionaire when is dot-com company was bought for $19,000,000.00 in stock options. It's quite amusing to see him fret about gaining or loosing several million a day depending upon how the stock market plays. It's also amusing to hear him say he needs more than $10,000,000.00 for a house.

He also belongs to a local Grateful Dead cover band, hense the music equipment.

This was the first time I've been to his house. It's a beautiful house and much larger than you would expect because of the all the stuff they (John and his wife) have. George Carlin had them in mind when he did his Stuff Routine.

The furniture moving process involved moving an entertainment center about a foot to the right, then juggling the placement of exercise equipment (“No, over there. The feng shui isn't right,” his wife said) and then the movement of a filecabinet from his former home office to the den. The major problem being the racks of clothes in his former home office.

Two commercial clothes racks of clothes. Two other rooms where filled with more commerical clothes racks. And shoes. Lots of shoes (“Celine Dion has over seven hundred pairs of shoes. That's my goal,” his wife also said). Pretty much all belonging to his wife.

“Our house it too small!” they both said.

“So, get rid of all this stuff,” I said. “Just toss it.” A horrified look crossed his wife's face. “Or pack the stuff and store it. After six months if you haven't gone back, toss it. You'll never miss it.”

“But I will,” she said.

Now I can see why John needs a $10,000,000.00 house.

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:, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

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.
