Tuesday, Aug 26, 2008 iPhone... I hate NDA
I’ve been working quite a lot on iPhone these days.
It’s quite fun working on iPhone apps cause the platform is very similar to Mac OS X and, usually, apps on iPhone are simple and easy to make :P
I’ve accumulated some sample code over the past few months… but… yuk… iPhone development is still under NDA. I can’t post or discuss the SDK stuff in details in public at all…
I wanna do an iPhone Dev Camp or stuff like that… crap… hate NDA... when will it get lifted??
Friday, Jul 25, 2008 First CocoaHeads Gathering
The first CocoaHeads gathering is over. It is a good one. We talked about some random topics and laid out a few topics for our next gathering.
We have settled with 2 major themes for the coming up gatherings – Ruby-Cocoa scripting and OpenGL. Thanks Chris and Folkert for picking up those 2 topics respectively. I actually feel really good that some people in the CocoaHeads gang are willing to be in charge in topics they are interested in. You know, this whole group is for us to share skills, interests and broaden our skill set.
I wanna pick up some Ruby for a long time… but I just don’t have the time to… well… I should say I m not committed to…
If you are interested in the Cocoa community in Hong Kong, please join our group in Facebook
See you in the next gathering (21 Aug)

Sunday, Jun 15, 2008 Setting up your slice
As you may know, I am now hosting the site in Slicehost. The experience is good so far.
One thing I like Slicehost over other VPS is community support. There are tons of useful articles for setting up and using your VPS with Slicehost. If you have intermediate server admin skill (like I do), you will find those articles very useful in helping you to set up things quick.
- Slicehost Wiki
- Setting up Ubuntu Hardy: page 1, page 2
Happy slicehosting :P
Tuesday, Jun 10, 2008 Using NSTreeController in NSOutlineView
I’ve been working on Core Data and using it to store hierarchical data. There are many discussions about this topic on the Internet. Here’s those I found useful to me:
- NSTreeController – Cocoadev
- NSOutlineView Bindings Help – Cocoadev
- NSTreeController Bug – Cocoadev
- NSTreeController bug or developer error – Cocoadev
- Core Data, NSTreeController & NSOutlineView – This isn’t extremely well written. But it does show a few common mistakes using Core data. Look at the comments left by other guys to know more.
- NSTreeController and Core Data, Sorted. – very well written post. I like him mentioning drag and drop in the article.
- AbstractTree – Sample code from Apple. Download it and check the index.html file. It does mention the “parent == nil” thing :P
Sunday, Jun 08, 2008 Hierarchical data in Core Data
Need to work out a way to store hierarchical data using Core data. Before hacking any code, it’s good to google around and see what others are doing :P
Found a nice article which study the performance of Core data with hierarchical data.
Testing Core Data with very big hierarchical data sets
Thanks Matt!!
