I have not been back to my iOS development since my Beijing vacation back. May be I am just too lazy or too busy with something else as excuse. One of reasons is that I want to do it in Xcode 4.0 and iOS 5. I got my Xcode updated last month. iOS will be released anytime soon either this month or in October.

Therefore, I have been thinking about adding a feature to zoom images in Blogger.

After I got my new iMac 27, I found a long list of updates, including OS and Thunderbolt updates. On the second day, I got another two updates. I have not had time to experience my iMac yet.

One thing I noticed immediately is that the process of checking new updates is much faster than before, less than 1 minute. The same process used to be taking long time. Not sure if this is one of enhancements or not. I think this should be belonging to Lion.

Yesterday I was asked to help to resolve some issues for a piece of PL/SQL codes, which was provided by our client support. I was working on only error issues, nothing related to its logic. I spent about 2 hours and finally almost got the script running OK (it was too late in the afternoon). Here are two notes about the work.

Open/Closed Principle: Delegate Example

Filed under: Programming Notes — David Chu @ 4:16 am
Tags: ,

In object-oriented programming, the open/closed principle is a very important principle. Software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification. Recently I tried to summary some commonly used components in a serials of documents. I found that I have used delegate in my LogHelper class. This reminds me about my OCP.

This is the first update after I installed Lion. It does not include any fix to add file size to Preview, as I want. I don’t think my voice will heard. Anyway, I just take two more steps to compare file size: to save file as JPEG and to use command+I to get file information. I am getting used to it.
