Why I built SolvoKu
Some projects are made not for the expected result, but for the journey to attain it.
SolvoKu was built with this in mind.

SoHO Viewer 1.5 submitted (approved)
I have just submitted an updated version of SoHO Viewer for review.
What is new in this version?
Improved downloading system with better state indicator.Images are now refreshed on screen as soon as the new picture is retrieved. For improving quality for iPhone 4 and iPad users, the images downloaded are now 1024*1024 instead of 512*512. Improved memory management and performance.
Edit:
SoHO Viewer 1.5 has been approved.
Ultra universal apps?
On Wednesday it was announced the future launch of the Mac App Store: a place to buy and download applications for your Mac, similarly to the AppStore for iPhone/iTouch/iPad.
This come from the will of making the Mac benefits of the experience acquired with the iPhone and the iPad.
The question that comes now to mind is: Will we now be able to build applications for being compatible with both iOS and Mac OS X? Or at least to build the two versions from a unique xCode project.
SohoViewer 1.6 (update)
An updated version of SoHO Viewer has been submitted to the AppStore and is currently waiting for review.
It's add the long awaited description of the instruments.
Next version will include French localization.
Update: This upgraded version has been approved and should been available in a few hours.
The reference-counted memory management system
Cocoa use a counter, the retainCount to know when an object must be deallocated.
When an object is initialized, its retainCount value is set to one, meaning "I am used at one place".
During it's life, this object may encounter several call to retain or release.
When retain is called, the retainCount value is incremented, meaning "I am used at one more place". Inversely, when release is called, the retainCount value is decremented. When the counter value reaches zero, the object is deallocated.
The autorelease method is a variant to the simple release one. When an object receive this message, it adds itself to the nearest autoreleasepool. When this pool is released or train, all objects that were put in it receive a release message.
You can create your own autoreleasepool, sometimes you must do it. There exist at least one pool in your program, located in the event loop.
Delegation
As I am writing from my phone, today's article will be short.
When creating your cocoa's application, you will often be asked to set a delegate object. This is not specific to objective-c development.
I will take a simple example : a table. There exists two ways two create cells in a table. The first one is active, we tell the table to add a cell, and we do so for each cell. The second one is passive. When the table want to be draw or updated, he ask our code what it should do.
How many rows should I have? What cell should I display there? What should I do when my cell is selected?
That is delegation. The answers are given by an instance of a class implementing an interface. This object is the delegate.
As a matter of fact, in iOS development, a UITableView use a double delegation. The delegate defines the behavior while the datasource defines the content.
