I was fortunate enough to get invited to the Google Wave Developer Preview program – on July 17, 2009. Today I found a way to embed the Google wave elsewhere using the Wave ID. So if you too are on Wave, we can have a collaborative discussion here.

An iPhone Developer Program (IDP) membership (costs $99 for Individuals) is required to officially deploy your application on the iPhone – even during the development and testing. Though I have applied for the IDP membership long ago, mine is yet to be approved. Perhaps India is not a listed country for IDP.

Not having an IDP membership will not affect your iPhone development and further testing on a real iPhone. But you would still require a Jailbroken iPhone. You will have to tweak your XCode (Version 3.1.2) and individual project settings – along with the iPhone (Firmware 2.2) – to get the Applications deployed on the phone. Here are the steps. These information were collated by the results of endless queries posted on different forums and by reading various material available on the Web. All the credits are due to their respective owners :)

Common Instructions to Install :-

• Jailbreaking the iPhone requires you to follow the clear instructions given by iClarified. This includes a Video demonstration also. There is no need to Unlock your iPhone. Just Jailbreak should suffice.

• Install the iPhoneTunnel and CyberDuck applications on the Mac

• Install OpenSSH, BossPrefs and Link-Identity-Editor applications using the Cydia application on the iPhone. After installation Reboot the iPhone

• Add source in Cydia (if you have not yet done so), please remember there is a slash (/) at the end of the url Code: http://www.iphone.org.hk/apt/ . Install MobileInstallation Patch version 2.2 in Section “Tweaks”

• Connect the iPhone using the USB Cable to the Mac

• Close the iTunes.

Setting up XCode to Compile and Build the iPhone Application

• Create a Signing Identify on your Mac by following this simple guide from Apple. I suggest you name the Certificate as “iPhone Developer”

• TextEdit the /Developer/Platforms/iPhoneOS.platform/Info.plist file to look the respective portions like:-

   1: <key>NATIVE_ARCH</key>

   2: <string>armv6</string>

   3: <key>PLIST_FILE_OUTPUT_FORMAT</key>

   4: <string>binary</string>

   5: <key>PROVISIONING_PROFILE_ALLOWED</key>

   6: <string>NO</string>

   7: <key>PROVISIONING_PROFILE_REQUIRED</key>

   8: <string>NO</string>

   9: <key>SDKROOT</key>

  10: <string>iphoneos2.2</string>

• Change your own Project Settings by taking [Menu] Project->Edit Project Settings. In the Properties List, find the Code-Signing-Identity and Select the Certificate Name(iPhone Developer) you created earlier.

• Add the following snippet on to your projects info.plist using TextEdit

   1: <key>SignerIdentity</key>

   2: <string>Apple iPhone OS Application Signing</string>

Transferring the Application Binary to the iPhone over USB

• You may duplicate the following steps using an Ad-Hoc WiFi connection too, of which I am not so fond off!. I prefer the USB.

• Start the iPhoneTunnel Application on the Mac. You should see a respective icon on the Superior Bar at the top of the screen. Click on that Icon and select [Turn Tunnel ON]

• Again click on the same icon on top and select [Tools->SFTP]. The Cyberduck should start automatically. Enter the username as ‘root’ and password as ‘alpine’ in the cyberduck login window.

• Copy the TestApp.app (Your Own App) to the /Application folder of the iPhone using Cyberduck

• Click on the iPhoneTunnel icon and select [Tools->SSH(root)]. Enter the root/alpine credentials at the command prompt.

• At this command prompt enter the following two commands:-

ldid -S /Applications/TestApp.app/TestApp

chmod +x /Applications/TestApp.app/TestApp

• Open the BossPrefs application on the iPhone and choose the “ReSpring” option. This will restart the SpringBoard application to show your application on the Home Screen.

• Enjoy Your App!

If you have a proper Code signing Signature from Apple , you can follow these great instructions to deploy on to AppStore.

Looks like things are going good on porting the Java VM on to iPhone. The fact is that iPhone is very well poised to run Java applications better than any other phone. Jay Freeman has been successful in porting the JamVM on to iPhone. JamVM is JSE 1.5 compatible. The core java classes has been ported already and Graphics and Media frameworks are being actively investigated. The current port is not optimised for the iPhone CPU. So expect it to run tad bit slow.

The iPhone offers a built in relational database in the form of SQLite. This is used to store information by the iPhone’s Notes application. Efforts are under way to offer a JDBC driver for this database too. The JamVM itself is pretty small – around 150k and uses the GNU Classpath libraries(9 MB). Compiling java source on iPhone is also possible now with Jikes ( upto jdk 1.4) or by using the Eclipse java compiler.

Please checkout the Java on iPhone development page for more details.

Reliance Developer Programme is having a contest to promote the development of useful mobile applications for the rural population. If you are a mobile application developer, it is now your chance to win up to Rs.13 Lacs in prize money.

The applications could be in any of the following areas:

Transportation
M- Commerce
Information
Health
Education
Governance
Location Based Services

This is really impressive and heartening to see. I have earlier covered some Microsoft India Mobile R&D initiatives to help improve the rural economy of India.

int i, sum = 0;

for ( i = 1; i < = LAST; i++ )
{
sum += i;
}
/*-for-*/
printf(“sum = %d\n”, sum);

I was amazed to see this page on Oracle reference books. They are all freely – available in both HTML and PDF format. You have plenty of top class official Oracle material on Performance tuning to XML Java API Reference. Even if you are only remotely connected with Oracle Products,  this Free Oracle Reference Books page is definitely worth a bookmark.

I use Oracle Spatial in one of the projects and found some great reference material out there.[Thanks to Murthy Kadam]

You can easily start a console window for Tomcat (most versions) by issuing the command:-

This will NOT run Tomcat as a background process. Very useful if you want to see a quick server log on the console without going through the log files.

Symbian is giving away free booklets on Symbian OS and UIQ development. There are even some translated booklets. If you are into mobile development, you must read them.

Better still – Symbian will even send you free printed versions of these booklets.
I especially liked the POSIX on Symbian OS booklet.[tags]symbian,free,books[/tags]

Steve Jobs won’t let you. Because he don’t trust you. You would leak the memory, make hidden resource calls and kill iPhone. Better Steve plugged it. 2007 Apple World Wide Developer Conference (WWDC), Steve gives you a penny. Go, Code for Safari. Do AJAX - and test them with this.

Lovely! AJAX games galore. Minesweeper anyone?.  Forget 3D games. iPhone is a Business phone, confirmed. So next you did a HandyShopper for iPhone. Great. What about handling a BT GPS Fix?. Sorry, you cannot. Live and die within Safari world. Though Nokia never said so. Probably, Steve wants us to VNC to Leopard from iPhone, for native apps ;)

Give me Java/Python/Ruby, Steve. They are harmless.
