• The Performance Cost Of Throwing Exceptions In ColdFusion

  Posted on Jul 17, 2009 at 11:59 PM

  Jose: I'd argue that exceptions should truly be reserved for "holy cow, I don't have a clue how to handle this" types of situations. They should not be used for easy-to-handle problems like missing attributes or basic error checking. It's a judgment call, and there aren't any har... read more »

• The Performance Cost Of Throwing Exceptions In ColdFusion

  Posted on Jul 17, 2009 at 7:51 PM

  Heh, thanks for this. I fight this battle, primarily with OO-purists, enough that I end up coding up something like this about once each year. Now I can just point and say "Ben said so, and he's too nice to lie to you". Exceptions are expensive. They are supposed to be expensive... read more »

  I think you're missing something crucial here, though. Not only are you paying for chicken (quality), but you are also paying for the service. Maybe not table service, but service nonetheless -- the implied service contract is that when you place an order you will only have a reasonable wait.read more »

• OOP Philosophy: Invalid State vs. Invalid Method Call

  Posted on Mar 23, 2009 at 10:47 PM

  Why wouldn't you extend the Account class with a TransferAmountTo(Amount, TargetAccount) method? I'm having trouble rationalizing why a transfer (an action verb) would be an object, which are traditionally nouns. You wouldn't want to take that transfer, serialize it, and move it someplace else,... read more »

• Making My ColdFusion Tags More Consistent

  Posted on Feb 25, 2009 at 9:13 PM

  The problem with cfset is that there are only 3 of the 4 components. You can think of it as either an implied verb or an implied noun: <cfset y=x> translates as: "cfset [stored] y from x" -- implied verb or "[cfset] set y from x" -- implied subject Admitte... read more »

  Blarg. This is why you don't comment at 1am. When I said "duck typing", I meant to say "method injection". I have no idea why it came out the other way. Cuckoo.... read more »

  Well, let me stop and reiterate definitions for each of those grammatical terms. Subject: The focus of the sentence. Verb: The action of the sentence. Indirect Object: The thing upon which the subject and verb are acting. read more »

  So it looks like you're doing subject - indirect object - verb - direct object ? I tend more to subject - verb - indirect object - direct object when I code. But as long as you are consistent, that's cool. My personal pet-peeve is the lack of consistency between YES/NO an... read more »

• Using A Rough Box Model To Gather Near-By Zip Codes

  You could also argue that, in many cases, doing any of this on the db server at all is now a moot point. If you use the Google Maps API correctly, you can have it send an AJAX request with the Lat/Lon bounding box. No math needed! I wrote up some proof-of-concept code for this a while bac... read more »

  I have to wonder how your performance would change if you built denormalized tables for common radius values. That is: CREATE TABLE Zip_50MI { start_zip INT NOT NULL, near_zip INT NOT NULL, distance_mi TINYINT NOT NULL } ALTER TABLE Zip_50MI ADD PRIMARY KEY (... read more »

  I second Brian's comment. As I was reading through the post I was thinking I'd have to find the same video. Pretty much all of the Crockford videos on Yahoo! are worth your time. Some of them get mind-bendingly complex, but they'll really open your eyes. Having said all of that, I'l... read more »
