Integrating your SaaS app with Yammer

Using Process.st just became even easier, thanks to our new Yammer integration. Since the general procedure for integrating with Yammer should be similar for most SaaS apps, I made a public template of the process:

How to add support for posting multipart forms to the Play Scala WS library

For Process Street‘s Yammer integration, I needed to post file attachments to their API using the Play Scala WS library.

However, it turns out that WS does not yet support uploading files using multipart/form-data and POST. There are several workarounds on the ‘net, but they all involve getting the underlying Ning Java client and doing thing manually.

Why not harness the power of Play and Scala and write our own Writeable to do that job? Heck, we already have a MultipartFormData object for handling multipart form requests, why not use that?

How to create an Angular directive for eonasdan’s Bootstrap datetime picker

I recently needed to add a DateTime picker to Process Street for use with our upcoming assignment feature. I ended up choosing eonasdan’s DateTime picker. Here’s the code to wrap it in an AngularJS directive:

…and here’s the code to include it in your AngularJS app:

How to convert a PostgreSQL UUID to bytea

I recently needed to convert a PostgreSQL UUID to bytea, and couldn’t find any quick one-liners on the web. So here it is, for your enjoyment:

Finding out the size of localStorage

In the next update of Process Street we are adding more caching to our front end JavaScript client (named Front Street after the street in Toronto) in an effort to make the experience of using our app as fast as possible.

Front Street uses web storage (specifically localStorage) to store persistent user data. To make the cache as effective as possible, it should be able to grow to use as much space as it can. However, we also store other information in localStorage, like user session information (the user’s login token and list of teams, for example). That means if the cache grew to use all the localStorage space, the app couldn’t function properly. Thus, we needed a way to detect the size of localStorage so we could partition localStorage between cache and session information.

Forcing HTTPS in a Play 2 Scala app

At Process Street we’ve been developing a new app called MailTheme that, like the Process Street app, it uses the Play Framework.

Unlike Process Street, MailTheme will be running on Google Cloud and, for the time being, won’t be behind a load balancer or proxy. As such, I needed to make all HTTP requests auto-redirect to HTTPS via Play. This turned out to be more difficult than I first imagined, as Play prior to version 2.3 has no way to detect whether or not the incoming request is over SSL.

Play 2 Framework not finding environment variables in IntelliJ IDEA on Mac

Recently I was experiencing an issue with the Play 2 Framework where it could not find environment variables on Mac OS when compiled within IntelliJ IDEA. The solution turned out to be simple, but could be inconvenient when an environment variable is used in many programs.

Pajama: Client and Server Validation Simplified

When implementing an HTML form that requires validation, a developer must make a decision: should I use client-side validation, server-side validation, or both?

In this article I will give a quick overview of the pros and cons of these validation techniques, as well as introduce my solution to the problem: Pajama.

Counting Syllables and Detecting Rhyme in PHP

I was looking at a Software Developer posting on the FreshBooks careers page the other day, and near the end of the “How to apply” instructions there was a curious sentence:

“If you want to prove you’re really paying attention, include a verse of ottava rima and a link to your GitHub profile with your application and you’re guaranteed to have your application reviewed by our Software Development Manager.”

I’d never heard of the ottava rima rhyming stanza form before, but a quick trip to Wikipedia remedied that. Essentially, an ottava rima stanza must satisfy three rules:

  1. Each stanza must have 8 lines,
  2. The lines must be iambic pentameter,
  3. The stanza must have the rhyming format a-b-a-b-a-b-c-c.

Here is an example of an ottava rima stanza by Frere (as given in the Wikipedia article):

But chiefly, when the shadowy moon had shed
O’er woods and waters her mysterious hue,
Their passive hearts and vacant fancies fed
With thoughts and aspirations strange and new,
Till their brute souls with inward working bred
Dark hints that in the depths of instinct grew
Subjection not from Locke’s associations,
Nor David Hartley’s doctrine of vibrations.

The simplicity of the rules got me thinking: how hard would it be to write a program to check if a poem stanza is ottava rima?

In this article, we will write a simple ottava rima detector in PHP.
