Early Access to My Next Book - Apache Cordova in Action

11-25-2014 931 views Mobile, JavaScript, HTML5, Books Comments

Hey - guess what? I'm working on a book. This time the publisher is Manning, and one of the cool things they do is allow early access to a book. You basically pay for it while it is being developed and you can provide feedback to help improve the text. Obviously you get corrected/new chapters as they come out as well. If this is appealing to you, you can head over to the book page now.

Status of Disqus updates, and a tool for URL migration

11-23-2014 786 views Misc Comments

Well, I'm disappointed to say the least. I've had good luck with Disqus pretty much everywhere I've used it, but my attempts to migrate my 50K+ comments over have been met with a great amount of difficulty. I'm not giving up, but hopefully my notes here will help others.

Check out FormKeep, another option for static sites

11-21-2014 920 views Development, JavaScript, HTML5 Comments

Over the past year or so I've been playing around with static site generators. After nearly fifteen years spent building dynamic web applications on the server-side, a simple solution involving a static site generator can be pretty darn appealing. Unfortunately, moving to static means you need to find alternatives for things that simply can't be static. Forms, forums, calendars, etc. I discussed options to handle this problem in my article for modernweb, Moving to Static and Keeping Your Toys. Today I'm going to introduce you to another option I discovered yesterday, FormKeep

ColdFusion Startup Issue with Hostname

So - this is kind of crazy. Yesterday I fired up ColdFusion 11 to test something and discovered that every request for a CFM returned an error. The error was a Null Pointer Exception so not terribly helpful. (Or so I thought.) I checked the logs and saw this:

Blog Migration Update

11-20-2014 1,024 views Misc Comments

Just a quick note. I've mentioned that I'm in the process of migrating the blog to a new platform (Wordpress). As part of that migration, I've went ahead and switched to Disqus. I'm still working on my export script (I'll share that when done) and since it will take up to 24 hours for the data to migrate (when I actually get the migration script even done!) I thought I'd take the plunge and enable it now.

However - that leaves me with having to display both the "old" comments (all 50,000+ of them) along with Disqus. I've done that now. Basically I just added the embed and removed the "Add Comment" form. I also put a little note so it was (hopefully) a bit obvious as to what in the heck was happening.

I know some folks aren't a fan of Disqus, but, going forward, this helps me make the blog a bit more migratable. (That's not a word and my editor is going to fuss at me. ;)

Determining installed plugins at runtime for Cordova and PhoneGap applications

11-19-2014 2,429 views Mobile, JavaScript, HTML5 1 Comment

Earlier today on Twitter a user asked an interesting question: How can I tell - via JavaScript - if a particular plugin is installed in a Cordova/PhoneGap application. I responded by asking how you wouldn't know since it is your own app, but then he mentioned that his code base was stand alone and would be used within other projects. (So basically - just JavaScript code that other Cordova/PhoneGap applications would use.)

Using the autodivider feature in jQuery Mobile (take two)

11-18-2014 2,865 views Mobile, jQuery, JavaScript, HTML5 8 Comments

Almost a year ago I blogged about using the autodivider feature in jQuery Mobile. This is a simple feature that enhances list views with dividers. It makes content a bit easier to parse when working with a large list.

One of my readers, Fher (who has a cool name - I kind of imagine her/him as a fire-breathing wolf), asked if there was a way to add a bubble count to the dividers. You can see an example of this on the docs for listview, but this is what the feature looks like:

So, the short answer is no, you can't do this with autodividers. Why? While the feature allows you to build a function to create dynamic dividers, it only lets you specify the text for the divider, not random HTML. However, if you are willing to give up having the "pretty bubble" effect, you can simply use it as part of the label. To make that work, I modified my code a bit from the previous demo (and again, you can read that here, I'd suggest checking it out just so you can see the context). Here is the complete JavaScript code. (The HTML didn't change.)

$(document).ready(function() {

	var dates = [
		"12/16/2013 12:00:00",
		"12/16/2013 14:00:00",		
		"12/17/2013 12:00:00",
		"12/18/2013 12:00:00",
		"12/19/2013 12:00:00",
		"12/19/2013 16:00:00"
	];

	var dateList = $("#dates");
	for(var i=0, len=dates.length; i<len; i++) {
		dateList.append("<li>"+dates[i]+"</li>");	
	}

	/*
	Create a generic func to return the label
	*/
	var getLabel = function(d) {
		return (d.getMonth()+1)+ "/" + d.getDate() + "/" + d.getFullYear();
	}
			
	/*
	Now that we have a func, use it to generate a label to count hash
	*/
	var dateCount = {};
	for(var i=0, len=dates.length; i<len; i++) {
		var l = getLabel(new Date(dates[i]));
		if(dateCount.hasOwnProperty(l)) {
			dateCount[l]++;
		} else {
			dateCount[l] = 1;
		}
	}
			
	dateList.listview({
		autodividers:true,
		autodividersSelector: function ( li ) {
			var d = new Date(li.text());
			var label = getLabel(d);
			
			return label + " (" +dateCount[label] +")";
		}
	}).listview("refresh");

});

The first change was to abstract out the code used to generate the divider - basically turning the date value into a label. Once I have that, I iterate over my data to figure out how many unique date labels I have. This is done with a simple object and a counter. Finally, my autodividersSelector function is modified to make use of this count. Here is the result.

There you go. Not exactly rocket science, but hopefully helpful. It is possible to create dividers with list bubbles, just not quite as simply as this entry demonstrates. I'll show that tomorrow.

Looking for Suggestions: Best Conferences for Mobile/Web Development

Cordova's copy-from tip

11-14-2014 3,785 views Mobile Comments

Yesterday I was proof-reading a blog post about an update to the PhoneGap CLI (which you should read - PhoneGap CLI 3.6.3) and I discovered something interesting. For a while now the Cordova CLI has had the ability to create a new project based on another. This is great because the default Cordova/PhoneGap application annoys the heck out of me.

Any WordPress users familiar with BlogCFC?

11-13-2014 1,836 views Misc 7 Comments

A long time ago a reader shared a BlogCFC to WordPress script. I'm assuming it is too far out of date to be useful. Has anyone converted a modern BlogCFC database to WordPress 4.0? I'm assuming I can figure it out myself, but if someone has a script handy, I'd appreciate it.
