We’re losing perspective on 3D CSS

August 27, 2013 § 1 Comment

Over the last few months we’ve seen quite a few interesting demos in 3D CSS. Some offer really nice UI interactions, others are built just to show us the capabilities of modern browsers blow our minds.

Workers are dumb

August 8, 2013 § Leave a comment

Workers are dumb
When doing heavy lifting in a webapp (anything from video transcoding to calling an API), a common practice is to take this heavy lifting out of the request and process it in the background. Doing so means the page can finish loading nice and quickly for the user. A common way to accomplish this is to use a message queue and workers. And workers are dumb.

Midem Music Hackday 2013

January 29, 2013 § Leave a comment

Carrying on from my post on the Mint site, I wanted to share a little more information on what I think was the coolest part of my MIDEM Music Hackday hack – the technology.

But first a quick recap of the idea for those in the dark:

To answer the question “what do you listen to?” I created an app that analyses your recent listening history and awards Artist, Genre, Guilty Pleasure and Hipster badges based on certain criteria.

With that out of the way…

October 15, 2012 § Leave a comment

This weekend I decided to have a go at making an app with edge Rails, aka Rails 4.0.0.beta. I hunted around for a summary of the cool new stuff and didn’t really find one. So, here is the interesting things I hit upon, more or less in the order I hit upon them:

Rails, callbacks, workers, and the race you never expected to lose

August 21, 2012 § 38 Comments

Consider a fairly normal pattern in a user model in Rails, sending a welcome email when a user signs up. If you’re interested in keeping your controller actions quick whilst you do this, you would probably queue the email to be sent later, like this:

class User < ActiveRecord::Base
  
  after_save :queue_welcome_email, :on => :create
  private
  def queue_welcome_email
    Resque.enqueue(WelcomeEmailJob, self.id)
  end
end
class WelcomeEmailJob
  @queue = :normal

  def self.perform(user_id)
    user = User.find(user_id)
    UserMailer.welcome_email(user).deliver
  end
end

Straightforward, right? You’d think so, but if you implemented this and ran it in a live system, you would find a small number of ActiveRecord::RecordNotFound errors cropping up in Resque.

Cross domain font woes – part 2

July 4, 2012 § 1 Comment

A few months back we looked at issues related to showing custom fonts in firefox (see Cross domain font woes in Firefox). Since then we have also started hosting more and more sites on heroku where you have no control over nginx. Obviously this makes the previously proposed solution hard to implement…plus who can remember all of that config?
