  • Sanity Checking Closure Invocation Overhead And Performance In Lucee 5.3.2.77

    Posted on Aug 7, 2019 at 5:23 PM

    I still have a hard time getting used to the "=>" notation for arrow functions. Maybe it's just my age, but I still like to see the word "function" in my closures. When my eyes encounter "=>" my brain interprets that as "equal to or greater than&quo... read more »

  • Using Email Yak To Provide Bidirectional Email Communication In Your Web Applications

    Posted on Dec 7, 2011 at 12:18 PM

    Nice find Ben, One of the things I like about a service like this is that you can use it to ensure that your outbound messages have indeed left your SMTP server. Sometimes IIS' built in SMTP service can get bogged down and lock up but if you can update a database field every time Email Yak receives... read more »

    @Kevin Duncan, Did you ever finish your project? I've been working on a new email delivery solution myself and I read your comment about yours nearly being done (in 2010). I would be curious to check out what you came up with if you still have it laying around.... read more »

  • ColdFusion, jQuery, And "AJAX" File Upload Demo

    Posted on Jul 19, 2011 at 7:03 PM

    @Tính Nguy?n There are a couple things you should check: 1. In the ColdFusion administrator under Java and JVM (ColdFusion 8 Admin) make sure your heap size is bigger than the file you want to upload. 1000 or 2000mb is good for large file uploads. 2. If you're using IIS7, you may need to change a v... read more »

  • Always Define Your ColdFusion Query Column Types

    Posted on Aug 18, 2009 at 2:05 AM

    Just had an idea... What if instead of passing a query object via AJAX you simply pass the SQL statement itself. You could always run the query in your calling template using MaxRows=0 and Result="result" to make sure it executes quickly and stores the SQL in a structure named "result". Then when... read more »

  • Always Define Your ColdFusion Query Column Types

    Posted on Aug 18, 2009 at 1:13 AM

    @Ben Definitely not a cop-out answer. You should see the pile of hair on my desk from trying to wrestle with this. I'm going to look like Mr. Clean in a few days. ;) Unfortunately the ColdFusion experiment I'm building requires me to send query objects via AJAX to another template and its very imp... read more »

  • Always Define Your ColdFusion Query Column Types

    Posted on Aug 15, 2009 at 2:57 PM

    I've been playing around with using JQuery to pass complex queries and strings all contained in a structure via AJAX. I've exprimented with sending the structure as a WDDX packet and as a JSON string. The WDDX method does an "ok" job at preserving the query column data types whereas the JSON metho... read more »

  • Am I The Only One Who Likes White Space In My ColdFusion Code?

    Posted on Jun 15, 2008 at 1:29 PM

    I come from a Design background and I have always considered myself a designer first and a coder/programmer second. I feel claustrophobic when I look at code that hasn't been tabbed or spaced out properly and I find that your examples Ben have been really easy on my eyes and make your sample code v... read more »
