Don’t Do Role-Based Authorization Checks; Do Activity-Based Checks 24 May, 2011. It was a Tuesday. I’ve built a few dozen security mechanisms in my career. Unfortunately, I kept getting it wrong, hence the need to keep building them. Over the years, though, I learned a number of different ways that a security system can be built. One of my favorite ways to build authorization systems is through th

MarionetteJS v1.0 25 March, 2013. It was a Monday. Hot on the heels of the Backbone v1.0 release, I present MarionetteJS v1.0! I quietly released it over the weekend, and I’m glad I did. I already had a bug report and have released v1.0.1 to fix it. 😀 The last few years of working on Marionette have been tremendously fun, exciting, frustrating at time, and have provided much more work and opportu

Managing Events As Relationships, Not Just References 6 February, 2013. It was a Wednesday. In my Scaling Backbone Apps With Marionette talk, I have some slides that deal with JavaScript zombies in Backbone apps. This isn’t a new subject by any means. It is one that I talk about a lot, and spend a lot of time explaining to others. But there is one aspect of this talk and the related material that

Backbone.js And JavaScript Garbage Collection 19 March, 2012. It was a Monday. A question was asked on Stack Overflow recently, and I provided an answer that I think is worth re-blogging here (while cleaning up the text / grammar). My answer goes in to a little bit of the idea behind a garbage collected language and gets in to some of the basics of how JavaScript knows when to clean up your “garba

Backbone.js Is Not An MVC Framework 23 December, 2011. It was a Friday. I’ve seen this question / statement / argument more than a few dozen times. I don’t particularly care whether or not people try to understand Backbone in terms of MVC frameworks, because that’s how we learn. We adapt new ideas based on existing knowledge experience, before we fully understand the new idea. However, I do care t

Asynchronously Load HTML Templates For Backbone Views 9 February, 2012. It was a Thursday. UPDATE: It turns out this is a really bad idea. Don’t async fetch individual templates. In the end, having done asynchronous fetching of individual templates on a few productions apps, it’s a really bad idea. The network latency and multiple requests that are made back to the server destroy any sense of spee

Why I’m done with Scrum 12 September, 2012. It was a Wednesday. My first foray into Agile was with a product team back in 2004-2005. It was my first “real” job out of college, and my first experience with a death march. During the death march, I was struck on how bad the idea of death marching was. Working weekends, long hours etc. were a sign of failure not on the development team, but our a fail

References, Routing, And The Event Aggregator: Coordinating Views In Backbone.js 19 July, 2011. It was a Tuesday. I recently found myself needing to facilitate communication between two backbone views. The first view is a medication – one that is currently being taken by a particular patient. The second view is the add/edit view that allows the patient to either add new medications or edit existin

Zombies! RUN! (Managing Page Transitions In Backbone Apps) 15 September, 2011. It was a Thursday. One of the common issues or questions I see for Backbone.js goes something like this: “Whenever I hit the same route more than once, I end up getting seeing this call being made multiple times. It seems to accumulate another call every time I hit the route. What’s going on?” or “I’ve noticed that my v

Using jQuery, Plugins and UI Controls With Backbone 20 February, 2012. It was a Monday. Most Backbone applications either use jQuery or Zepto as their DOM manipulation of choice. I tend to use jQuery as it’s supported across more browsers and has more features – though it is a little heavier in terms of download size (and maybe performance). I also use a lot of jQuery plugins for various controls,

JavaScript Closures Explained 17 February, 2012. It was a Friday. If you write any code in JavaScript then you’ve probably used closures, but do you actually understand what they are and how they work?  Taking the time to understand closures and how they’re implemented can add a deeper dimension to your understanding of the JavaScript language.  In this article, I’ll discuss what closures are and
