Pjax is a nice way to get a responsive web app. It has a similar effect as a single-page javascript/json app, but allows for more conventional server-side programming and easier fallback for old browsers.

Coffeescript classes: Coffeescript-style or Crockford-style?

eamonn — Sun, 05 Feb 2012 07:40:35 +0000

Here are two different ways of defining a class in Coffeescript:

class Container

  constructor: (@member) ->

  secret = 3

  dec = ->
    if secret > 0
      secret -= 1
      true
    else
      false

  service : ->
    if dec() then @member else null

Container::stamp = (string) ->
  @member + string

Container = (param) ->

  @member = param
  secret = 3

  dec = ->
    if secret > 0
      secret -= 1
      true
    else
      false

  @service = ->
    if dec() then @member else null

  null

Container::stamp = (string) ->
  @member + string

Both of these define a class called Container with

a public field member initialized by a constructor parameter
a private field secret
a private method dec
a privileged method service
a public method stamp

We can use both in the same way:

myContainer = new Container 'abc'

console.log  myContainer.member      # abc
console.log  myContainer.stamp 'def' # abcdef
console.log  myContainer.service()   # abc
console.log  myContainer.service()   # abc
console.log  myContainer.service()   # abc
console.log  myContainer.service()   # null

The version above on the left is the special class syntax that Coffeescript provides. However, to me, this extra layer of syntax seems to depart a bit from the “Coffeescript is just JavaScript” philosophy.

The version above on the right is a translation of Douglas Crockford’s pattern, using his example.

Which is better? The left is a bit easier to read for a newcomer to the language, but I find the right more elegant because there is less “magic”.

And there is another advantage to the Crockford style. Consider this small modification:

Container = (param, decrementBy) ->

  @member = param
  secret = 3

  dec = ->
    if secret > 0
      secret -= decrementBy
      true
    else
      false

  @service = ->
    if dec() then @member else null

  null

Container::stamp = (string) ->
  @member + string

Here we have generalized the class by adding a decrementBy parameter to the constructor. We do not copy this to a property, but any of the private or privileged methods in the class can use it. (Don’t you love closures!). There is no way to do this using the Coffeescript class syntax in a way that would prevent the decrementBy value being modified from outside the object.

I think I might switch to using the Crockford-style classes.

Generalized continuous compiling (like sbt or coffeescript)

eamonn — Tue, 24 Jan 2012 18:57:28 +0000

One of the really nice things about the sbt build system (for building Scala projects) or the coffeescript compiler is that they have a “watch” mode.

When you invoke a command in that mode (prepending with “~” (tilde) in sbt or adding the “–watch” argument to coffee) they continuously monitor your files and execute the compile or build action as soon as you save one of your source files to disk. Some IDEs, such as Eclipse, have that feature too — saving a file triggers an immediately compile.

But what if you are using an older build system like make, ant, or maven?

Well, if you are working on Linux, you can add this continuous build mode to any build system.

First, install inotify-tools, which on Ubuntu and similar distributions means doing:

sudo apt-get install inotify-tools

Then, for make, create an executable script called “~make” somewhere in your path with the following contents

#!/bin/sh -x

make $*
while inotifywait -e modify .
do
  make $*
done

Now where you would normally type

make something

you can type

~make something

and start editing files. Every time you save a file the make will execute.

For ant, maven, or any other command-line build system, just modify the script to replace “make” in the two places it occurs.

When the worm turns: will consumers rebel against large-scale collection and analysis of their data?

Will Data Collection on User Behaviour Be Forced to End Soon?

Interesting point of view on possible push-back from consumers on the massive collection of data about them. One particular quote:

no one had yet found a way to articulate the value proposition of aggregate data analysis to end consumers because there wasn’t one yet

In other words, while there is a lot of value to companies of the data gathered about consumers, but there is not much value to the consumers themselves.

Don’t confuse Users with Customers

eamonn — Sat, 07 Jan 2012 05:54:02 +0000

If your users are also your customers, then you are lucky. It makes a lot of design and marketing decisions a lot simpler. You can focus laser-like on providing features that your users are willing to pay for.

However the user is not always the customer. For example, if you are selling software to a large enterprise then the person making the buying decision is not the user, which is why so much software used internally in large companies is so crappy.

And many of you working in the consumer Internet space have the same business model that broadcast television has had for more than half a century: give the service for free to users and get money from advertisers. To be successful you need to simultaneously keep your users (consumers) happy while keeping your customers (advertisers) willing to pay you. This is often hard.
