In a lot of modern web applications, the front-end ends up receiving query result as a JSON object and the result is then formatted on the client-side. In this post, I am going to show how you can use the JavaScript ‘filter()’ method to filter the results in different ways.

I have been playing around with the Web Cryptography API a lot lately. My most recent post was about getRandomValues(). I wanted to take a moment to investigate two more methods: generateKey() and exportKey(). The generation of a good cryptographic key is fairly fundamental. I wrote up a short demo app, to demonstrate how the two …

The W3C has been working on a Web Cryptography API for a while, now. The current version (11 December 2014) is their “Candidate Recommendation”. As such, I would not necessarily consider it fully ready for primetime but that does not mean that we can not play around with it a bit. I figured that today, we should …
Continue reading "Generating random numbers with the Web Cryptography API"These days, the lines between the web and the local environment can be very blurry. There is a web API called FileReader() that nicely adds to that blurriness. It lets you asynchronously read the contents of a file on the user’s computer. I am going to show you one way of using it. So, …

In my day job, I have been writing a lot of JavaScript. The system already heavily uses jQuery and the addition of Angular would have been a tough sell. I started to look for an alternative to handle data binding and templating.

Lately, I have been working with a lot of legacy SQL and this has caused me to think about what makes SQL (and database designs) good and bad. There is a concept called ACID, defined within ISO/IEC 10026-1:1992. ACID is an acronym, that stands for Atomicity, Consistency, Isolation, and Durability.

I needed a way of allowing a person to uniquely select a movie. You don’t want to just give the user a free-form box because of the 52 different ways you could input …

I have been intending to revisit Pocket Joe, in the near future. When I do so, I want to include my social media feeds. No matter how much I blog, I am always going to post to Twitter and Google+ more often. So, how do you include your public Google+ feed in your app?

For this post, I created an example app that I am calling “Notes Vault.” My primary goal was to check out ngStorage but in doing so I also explored ng-options and ng-model. Let us take a look at the end result.

I have been meaning to to explore the capabilities of AngularJS a little more, so I whipped up this small demo app. It takes your zip code (hard-coded into the JavaScript file), queries a YQL API, and displays a listing of the nearest NPR stations. It is not the most unique piece of code but …
