What's wrong with Netmag's "Optimize your JavaScript" post

What's wrong with Netmag's "Optimize your JavaScript" post

Update: The original post on Netmag has been updated since this was written.

I tweeted earlier that this should be retracted. Generally, these performance-related articles are essentially little more than linkbait -- there are perhaps an infinite number of things you should do to improve a page's performance before worrying about the purported perf hit of multiplication vs. division -- but this post went further than most in this genre: it offered patently inaccurate and misleading advice.

Here are a few examples, assembled by some people who actually know what they're talking about (largely Rick Waldron and Ben Alman, with some help from myself and several others from the place that shall be unnamed).

Things that are just plain wrong

You're Missing the Point of Promises

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

In other words, the following asynchronous code:

var d = Domain.create()

d.on("error", function (error) {
    console.error("Error with the twitterverse:", error)
})

d.enter()

EtherCalc Chapter for the upcoming book "The Performance of Open Source Applications" - Draft - comments welcome!

From SocialCalc to EtherCalc

Previously, in The Architecture of Open Source Applications, I described SocialCalc, an in-browser spreadsheet system that replaced the server-centric WikiCalc architecture. SocialCalc performs all of its computations in the browser; it uses the server only for loading and saving spreadsheets.

For the Socialtext team, performance was the primary goal behind SocialCalc's design in 2006. The key observation was this: Client-side computation in JavaScript, while an order of magnitude slower than server-side computation in Perl, was still much faster than the network latency incurred during AJAX roundtrips:

Upgrade Django from 1.1 to 1.5.1. This highlights some of the issues that one may encounter when updating Django. It's not possible to cover every case, but this should provide a good general starting point.

Upgrade Django from 1.1 to 1.5.1. This highlights some of the issues that one may encounter when updating Django. It's not possible to cover every case, but this should provide a good general starting point.

Change to DATABASES variable in settings.py.

Django now supports multiple databases and changes are needed to how the database connections are defined.

  • Changed in Django 1.2
  • Change Required by Django 1.4
