"It seems that perfection is reached not when there is nothing left to add, but when there is nothing left to take away." –Antoine de Saint Exupéry
Why John Siracusa is right. Currently there is a already more than 30 messages long discussion on cocoa-dev about how to implement a singleton – the most simple design pattern known – in Obj-C. Apple is missing a garbage-collected language!
Update: Also see the article “Can Apple do Better than Objective-C?” from Nitesh Dhanjani at macdevcenter.

I do often need to keep a list of todo items or other things I shouldn’t forget about. To keep things simple (with a limited but simple user interface and as an alternative to a full blown text editor or other outlining applications (e.g. OmniOutliner) I have written a tiny little application (called Changelog.app, as I keep the changes planned for future updates to Cyberduck.app in it.) which suits most of my needs. Every document can have a list of different subjects (on the left in the screenshot) with some text (standard NSTextView with ruler, font and color panel). Among the features are Undo/Redo, Autosave, Document-Based, Printing, etc…

This is a small sample application I made together with Carl-Johan Kihlbom at the WWDC Student Sunday to fetch books from amazon and save them in a library for future reference. It is a document-based application which was created for the sole purpose to show how to make use of Core Data. Now that this page is a blog it is easier to post those little things (…)

You shall not forget the Manifesto for Agile Software Development
We are uncovering better ways of developing

Responding to change over following a plan
That is, while there is value in the items on
the right, we value the items on the left more.
See agilemanifesto.org for more about it.
