• Experimenting With ByteBuffer In ColdFusion For Binary Manipulation

  Posted on Oct 13, 2016 at 7:40 AM

  Thanks, Ben. I've just done some quick and dirty testing using Lucee comparing ByteArrayOutputStream vs ByteBuffer when converting a fairly large spreadsheet java object to a binary of around 8MB, and I'm not seeing much difference in performance, but perhaps with even larger amounts of data it woul... read more »

  Hi Ben, this is useful stuff. Would you mind posting links to the articles you mention which recommend ByteBuffer over ByteArrayOutputStream?... read more »

• MySQL GROUP_CONCAT() Fails Silently When It Hits Its Size Limit

  Posted on Feb 11, 2016 at 5:00 AM

  @Raffael Using @@ before the variable in the SET statement restricts the change to the current database connection rather than overriding the global server setting. How long the connection will last depends on your settings, but I think the default is normally 20 minutes for Adobe ColdFusion. If y... read more »

• MySQL GROUP_CONCAT() Fails Silently When It Hits Its Size Limit

  Posted on Aug 14, 2014 at 5:46 AM

  I precede all my uses of GROUP_CONCAT with <cfquery datasource="test"> SET @@group_concat_max_len = 9999999; </cfquery> It's a great tool for de-normalising data, such as when populating a search index.... read more »

• MySQL GROUP_CONCAT() Has Buggy Interaction With UNION Clauses

  Posted on Aug 14, 2014 at 3:54 AM

  I'm getting 147 throughout using MariaDB 10.0.x (which matches MySQL 5.5/6). I use GROUP_CONCAT quite a bit, including with UNION statements, and it's always seemed pretty reliable.... read more »

• Dumping Out The CGI Scope Does Not List All Available CGI Values In ColdFusion

  @Jim. Yup, CF has the ternary operator, but not the Elvis operator.... read more »

• Dumping Out The CGI Scope Does Not List All Available CGI Values In ColdFusion

  Posted on Oct 15, 2013 at 4:20 AM

  @Jason The "Elvis operator" is the "?:" in Ben's second example. CF9 doesn't support this and I don't believe CF10 does either, but Railo 4.1 does. I think you must mean the "ternery operator" in Ben's first example.... read more »

• AsyncTaskQueue.cfc - Running Low-Priority Tasks In A Single CFThread

  Posted on Sep 16, 2013 at 3:49 AM

  @Dan From the CF9.0.1 Standard Admin > Request Tuning > Tag Limit Settings > Maximum number of threads available for CFTHREAD: "On Standard Edition, the maximum limit is 10." I wonder if it started off as 2 and was increased with 9.0.1 perhaps?... read more »

• Quiet: The Power Of Introverts In A World That Can't Stop Talking By Susan Cain

  Posted on Jul 19, 2012 at 2:39 AM

  Fascinating, Larry. I thought research on this area started with Jung - had no idea it went back to Pavlov. Thanks for the insight.... read more »

• Quiet: The Power Of Introverts In A World That Can't Stop Talking By Susan Cain

  Posted on Jul 18, 2012 at 4:23 PM

  Very interesting, Larry, thanks. You should read Cain if you haven't. She cites Eysenck's studies of arousal, and subsequent critiques. My point, and hers, is really that today's culture uses labels such as "phobia" and "drawback" to signal that the opposite qualities are what w... read more »

• Quiet: The Power Of Introverts In A World That Can't Stop Talking By Susan Cain

  Posted on Jul 18, 2012 at 2:54 PM

  @Larry "That said introversion has some serious drawbacks, neophobia - fear of the new" Cain argues that had the financial gunslingers who contributed to our current economic woes taken a more risk-averse approach, things might have turned out better. Personally I back her campaign to ... read more »

• Quiet: The Power Of Introverts In A World That Can't Stop Talking By Susan Cain

  Posted on Jul 14, 2012 at 6:10 PM

  Great review, Ben. What I like about Quiet is that it's not primarily a self-help book. She does offer some good advice, but her main purpose seems to be to campaign for a higher value to be placed on quiet, thoughtful people - or in fact a return to the values of an age when integrity mattered more... read more »

• Using The RequireJS Build / Optimizer To Concatenate Modularized CSS Files

  Posted on Jan 12, 2012 at 4:36 AM

  Ben, for a CF approach to modularising JS and CSS check out Dominic Watson's superb CfStatic: http://cfsimplicity.com/43/the-simplicity-of-cfstatic As well as concatenation it will also minify and compile LESS CSS syntax, as recommended by Nelle.... read more »

• Using Google's Targeted Site Search Protocol To Search My Site

  Posted on Sep 18, 2011 at 4:49 AM

  Ben, I was considering Google for my static blog's search, but ended up with a much more satisfactory integrated solution. http://cfsimplicity.com/39/integrated-search-for-a-static-website-part-1 Haven't got round to posting the details yet, but as a JS guru I'm sure you'd come up with something... read more »
