If you’re a ColdFusion or CFML junkie, reading Mod Media’s “What You Didn’t Know About CFML” won’t tell you anything new – but your employer or client might learn a thing or two ;-)

The Mod Media Infographic: Wat You Didn't Know About CFML

The Mod Media Infographic: Wat You Didn’t Know About CFML

As if to prove the point, just today I noticed two CFML-based websites. Scientific American clearly runs CFML code to display pages (page.cfm), articles (article.cfm) and more, and Belgian technology news site smartbiz.be proudly proclaims ‘ColdFusion Powered by Railo‘.

So don’t let anyone tell you that CFML is dead!

I’m currently attending an ‘Advanced Developer’ training for SharePoint 2010, so I think it’s a good idea to keep track of some of the tools that can help with SharePoint development. If I’m to believe Google, this SharePoint Developer Tools list on Listly seems to be the ‘best’ overview. ‘CKS – Development Tools Edition for Visual Studio‘ and ‘ULS Viewer‘ were already mentioned and used during our training, by the way. I’m pretty sure there are versions of these for SharePoint 2013 as well.

Some of the tools mentioned are hardly specific to Sharepoint, though, and would be better catalogued as ‘web developer tools’. Oh well, if that helps new SharePoint developers to pick up a few serious tools…

I’m still cleaning up my home office, and it will take a lot more time – I’m going about it very slowly. Anyway, this is my find of the day:

May 1999 - Free BSD and Allaire ColdFusion 4 on a single CD-ROM

May 1999 – Free BSD and Allaire ColdFusion 4 on a single CD-ROM

Strangely enough, the CD-ROM wouldn’t boot up an old PC with a 700Mhz Athlon CPU and 256KB of RAM – but that PC isn’t exactly new either, and I haven’t used it in more than a year. Recycling that PC seems to be the best option now ;-)

Last wednesday Adobe hosted a Belgian ColdFusion User Group meeting. Subjects of meeting were Less and Bootstrap. I liked the Bootstrap demos given by Guust Nieuwenhuis, all the while thinking about how Boostrap would have simplified my life (and that of my colleagues) while developing our intranet apps more than five years ago. .. but that was before HTML5 was there to build on…

If you want a quick intro to Bootstrap without going to a user group meeting, have a look at Matt Raible’s extensive Bootstrap overview (he describes the creation of this presentation app in his blog post of April 23, 2013).

The following jQuery 1.6 code snippet works (or at least it seems to work) in Chrome 24 and Firefox 20, but not in IE8: IE8 keeps showing me the “missing image” graphic when the requested image does not exist on the server. Why?

$.ajax( $("#prod").val() + ".jpg", {
  type: "GET",
  data: "{}",
  error: function() { $("#preview").html( "" ) },
  fail: function() { $("#preview").html( "" ) },
  done: function() {
  success: function() {

If it wasn’t clear: I’m trying to check the existence of a JPEG file on the webserver before showing it in a DIV with the id “preview”, where the JPEG is named after the OPTION value in the “prod” SELECT. The code snippet should be packaged in a function called when the user changes the product selection, of course. I have tried a few variants of the code, having started with “$.get()“, but none of them worked as expected.

I have found a few mentions of IE8 trouble with the “$.ajax()” function, like these: http://forum.jquery.com/topic/jquery-ajax-ie8-problem or https://github.com/angular/angular.js/issues/1418. I’m yet to find an clear explanation for what might go wrong with my simple HTTP GET, however…

Do I really have to give up on jQuery in order to get it running on the admittedly antiquated IE8, and apply the solution presented on StackOverflow: http://stackoverflow.com/questions/2659208/ie8-jquery-ajax-call-giving-parsererror-from-django-for-json-data-which-seem? Or is there a better solution without jQuery?

TechRadar uses strong wording to explain the WebRTC project: “The web has revolutionised communication, and WebRTC promises to take the revolution a step further. The free, open-source project enables compliant web browsers to communicate in real-time using simple JavaScript APIs”. Read the whole article titled “WebRTC uncovered: why it’s the future of online communications” for more details.

As to WebRTC replacing Skype c.s.: perhaps these tools will add WebRTC to their palette of communications protocols, rather than being replaced by it…

Wiki’s are no longer the spearpoint of the ‘social media’ that they were a few years ago. That does not mean they have gone away or, worse, have become irrelevant. It’s good to see that a major player like Ars Technica publishes a nice Mediawiki installation manual: “Web Served 7: Wiki wiki wiki!“.

The rest of the ‘Web served’ series – on how to setup and use a secure webserver – is worth reading as well, if you have little or no experience with the subject.
