Just a friendly reminder about the ColdBox Connection meeting today at noon Central. ColdBox Connection is an online webinar that is held every two weeks by Team ColdBox to showcase a part of the ColdBox Platform and answer your questions. Today's is being hosted by Aaron Greenlee and will be discussing CacheBox, the enterprise caching framework which is baked into ColdBox as well as available as a separate utility for your existing apps.

Here is the Connect room: http://experts.adobeconnect.com/coldbox-connection/

Hope you see you there!

In a recent pissing match between ColdFusion and PHP, Jared Rypka-Hauer was demonstrating the performance of a function that generated prime numbers. The discussion really wasn't about the BEST prime generator as much as it was about how much ColdFusion can kick PHP's puny butt all over town. Never the less, I piped up in the comments to ask Jared to compare a prime number generator that I wrote a while back based on the Sieve of Eratosthene. After Jared asked some good questions about how my code worked I figured it was time I stopped high-jacking the comments of the PHP pooper train. I decided to spin off a new post to highlight some significant performance gains I was able to produce.

I found an interesting little bug in the BlogCFC implementation of ColdFISH today. ColdFISH is a ColdFusion code formatting component that is instantiated once and cached as a singleton in the application scope in BlogCFC. The problem is, ColdFISH looks like it wasn't intended to be used as a singleton. It makes use of the variables scope to store the Java StringBuffer class it uses to gather up your formatted code as well as a number of other variables used to parse the code it is formatting. This means when two or more people hit a BlogCFC entry with larger code samples, race conditions exists.

Our friends at Webapper are giving away free copies of SeeFusion (an awesome ColdFusion server monitoring tool) to the first 100 200 people to take their survey on ColdFusion consulting. Go check out here:

UPDATE: Webapper is now going to give away SeeFusion to the first 200 people to take their survey. Can't beat that!

I threw some AdSense ads on my site the other day. I don't think I'll be getting rich any time soon though. I'm up to 58 cents so I figure I'll be seeing a check from Google in about 8 years. :) Anyway, while troubleshooting an error in my blogCFC I noticed I kept getting each error E-mail three times. Looking at the User Agent showed that "Mediapartners-Google" was hitting every URL I hit twice. Incidentally, I have two Google ads on every page of my site.

My coworker found this interesting little SQL Server behavior today that was quite startling at first glance. It's like punching 2 + 2 into your calculator and having the result come back as 5. After pin-pointing the cause for the behavior, it ALMOST makes sense... except for the fact that it doesn't make sense at all. It involves a randomized sub-select and table variables.

I've never kept too quiet about my affection for SeeFusion as a ColdFusion monitoring tool. I use it for debugging, performance monitoring, and basic metrics gathering. Here's an old note on the JDBC URL wrappers that I found myself digging up last week. I don't even think you can find this nugget on the official SeeFusion site.

Here's another UDF I was tinkering with last week. I wanted to be able to count all of the numbers that divided evenly into a given integer. I couldn't find a ColdFusion implementation, so after getting some advice from Stack Overflow I created my own.

Ahh... the quintessential math problem-- finding prime numbers. Last week while tinkering with a math challenge I needed to find all of the primes up to a given number. There was a version on cflib.org, but I thought I could do it in less code, so I dug in myself.
