New Version Main Screen

Before going to the detail, let’s cover things that we updated.

• Alarm when it detects shaking motion
• Sampling rate is adjustable
• Show time lines On/Off option
• Real-Time Drawing On/Off option for stable sampling rate
• High-Pass Filter On/Off option
• Send Data without location information
• Report the Earthquake option
• Better Web Interface with Flash Chart Module (available only from your desktop/laptop)
• Improved Spectrum Drawing

Since some people suggested us to place some indicators that you can drag and scroll the screen while it’s stopped. We placed the arrow indicators. Please try pausing it and scroll with your finger.

Drag with your finger to scroll back

It draws lines with anti-aliasing. We will increase the capture length and multiple saving slots in the next update (ver 1.2).

I am also a graduate student in Earth and Environment Science major in Long Island University, and that’s why iSeismometer project started. Recently, Dr. Kennelly who is Assistant Professor of Geography and I published a research paper. We also submitted grant proposal to USGS to get more funding. Daily News covered us about this project . We asked a web designer to create flash movie to introduce our concept. A lot of activities are going on here. Let’s see how it goes.

Another big improvement is on the Spectrum screen. This is a bit geek talk so you can skip if you are not interested in (let’s go download iSeismometer in iTunes).

(image source : xkcd.com)

The Spectrum screen is my journey to find out “how many times you shake your iPhone within certain duration?”. Hopefully, this is going to detect the earthquake waves in the future because seismic waves often shows repetitive patterns. Our first version of iSeismometer draws the spectrum with a regular Fourier transform algorithm. This works ok on my macbook while I’m developing. Then, I had a performance problem on my device because the resource is limited. It was taking forever to calculate data for more than 1500 signals (you know, meaning of forever in our generation). In the current version, it incorporates the fast Fourier transform. This dramatically improved the performance of drawing spectrum analysis based on “divide and conquer” method. However, there is a drawback; which is the number of samples is limited to 2^n (e.g. 128,256, and 1024). This is the actual performance improvement:

Regular FT vs. FFT

The graph shows different performance for each data.  As we expected when we changed the algorithm from O(N^2) to O(N.log N), time to calculate larger amount of data increases a lot for the first version while the new version stays within 0.1 second. The cost of computation stabilized just like the textbook’s sorting algorithm demo. This is very good example for Computer Science 102 kind class.

Very good!

Spectrum Screen

Nowadays,  we use powerful machines and mature high-level language with garbage collectors. We, programmers, often forget those basic tune-ups what Dijkstra offered long time ago. Programming in Objective-C with a limited environment (e.g. mobile phones) is a nice training for me because I’m one of .NET developers who use very rich resources in my work place.

I still remember that my first Computer Science professor told me. “Memorizing API is not so important. Understanding the algorithms is important. Because those API might be dead in few years but the algorithm is not. You can use the core idea in everywhere, over and over again.”

Brian Gillett, The original creator of mailbox find collaborated with ObjectGraph to improve his existing mailbox find app.

We decided to scrap the old code and rebuild the app from scratch using what I have learned by writing blog posts about mapkit usage in iPhone SDK.

Our designer did a splendid job with the app icons, splash screen and the pins used to identify various mailboxes, ups, fedex and post office locations.

A couple of interesting things were learnt during the creation of this app like

• Calculating span dynamically
• custom sqlite database with math functions like sin and cos
• gzip compression to reduce size of the database

All you need to understand are 2 classes.

GKPeerPickerController and GKSession

You could create your own interface for establishing connection between 2 devices, but Apple provides a nice interface via the GKPeerPickerController

As with the Map Kit and other frameworks supported by Apple, they use the powerful delegate pattern to accomplish communication between the devices.

As such there are two delegates you need to make yourself familiar with. They are

GKPeerPickerControllerDelegate and GKSessionDelegate

Just create a simple View based project, Add Game Kit framework to your project, then Just go to your controller and implement the 2 delegates from above. Here is my code, My project is named GameKitTest, thus the name of the file GameKitTestController

The data transfer between the clients happens using NSData objects. For purposes of this discussion you just need to know how to convert back and forth from NSData to NSString. Here is a quick snippet

From NSString to NSData:

1
2

NSString* aStr;
aStr = [[NSString alloc] initWithData:aData encoding:NSASCIIStringEncoding];

From NSData to NSString:

1
2

NSData* aData;
aData = [aStr dataUsingEncoding: NSASCIIStringEncoding];

OK, Now with our further adieu here is the code

The reason why windows was soo successful was due to the fact the developers could create applications for it and kind of reach 90% of the market with it.

Once the application is successful enough, then try to tackle the 10% of the market. But with mobile platforms this is not the case.

iPhone is the leader of the pack now, with almost 60K apps on the app store and some interesting stories about developers becoming millionaires by writing software for it. But how long will this dominance continue?

The biggest problem for iPhone is its limitation of the screen resolution to 320×480. Now they are boxed in to this.

If you read the palm documentation it specifically says design your applications for more flexible display resolutions.

What is iPhone going to do when higher resolutions come in to play? They will be in the same box as of microsoft

“BACKWARD COMPATIBILITY”

Bill Gates book “The Road Ahead” said that the reason for the success of the windows platform was due to what he called a “Positive Cycle”, More developers develop for a platform, the platform becomes attractive to consumers, the more consumers use the platform, more developers join the platform.

Kind of like an infinite loop. But what he forgot to mention is the problem that is plaguing all windows products to this day. To satisfy the developers that created programs for it when it was just a toy, it has to stick to the same architecture.

Now there are 4 major players for mobile apps.

- iPhone
- Android
- Palm Pre
- Blackberry

I dont even consider Windows mobile as a competitor until it gets it act together with solid specifications for device manufacturers, so developers could assume some kind of sameness across various mobile devices.

Developing for each separately is a pain in the ass. You will need to learn a different set of languages/ tools for each one of them.

Although some languages go across these platforms (Java is used for both Android and Blackberry), the APIs are different.

Palm made a good decision of building their entire UI on a browser based framework (Javascript + CSS +HTML), so it will be the easiest to develop for. But I am still not sure about 3D graphics and good development tools for the platform.

Android and Blackberry have mature development toolkits. But Blackberry again goes into the same “BACKWARD COMPATIBILITY” loop with multitude of devices with different screen resolutions and different capabilities.

It kind of makes us get Java back as its original purpose of WORM (Write once Run many) with a standard tool kit.

I guess for the time being, we are stuck with creating different programs for different platforms and different devices.

God Help Us All Developers

Here is me developing for 3 platforms (iPhone, Android and Palm Pre)

You can see his stuff here

Anyway after simply checking(svn co) out his repository, I was able to quickly build a simple client very quickly

Here is version 0.000001 alpha

Matt nicely uses the standard way of doing things in objetive c with async calls

- Delegate – call back mechanism

Your View Controller or what ever has to simply implement the protocol MGTwitterEngineDelegate and you are getting responses from Twitter

Here is my code

1
2
3

twitterEngine=[[MGTwitterEngine alloc] initWithDelegate:self];
[twitterEngine setUsername:@"yourusername" password:@"yourpassword"];
[twitterEngine getRepliesStartingAtPage:0];

And just implement the callback to get the responses. All responses are nicely packed within an NSArray. Each element is a NSDictionary.. real nice. Oh and for testing NSLog will just spit everything out for your convenience

Here is my code to show the results in a TableView

Explaining how it works:

http://www.objectgraph.com/dictionary/how.html

I created it as i was trying to understand how XMLHttpRequest object worked in Google Suggest Project. There were really no examples around except for one really clear example from Apple.

http://developer.apple.com/internet/webcontent/xmlhttpreq.html

It was covered on TechCrunch on September of 2005

http://www.techcrunch.com/2005/09/19/ajax-dictionary-objectgraph/

So now we come full circle, I just released the same application on the iPhone platform. I wanted to target both the iPhone and iPod Touch users and not make the user connect to internet (in case of iPod touch) just to look up a word in the dictionary

The challenge was to squeeze 180k+ words inside the iPhone database and still make it as responsive as a real Oracle/SQL Server database efficiency using sqlite3.

So finally i figured the best way would be to break the database down into smaller chunks. I took the obvious route of breaking it down by different letters the word starts with.

Based on the user input the proper database is selected on the fly and the query is instantaneous.

The final app size was 20MB. I wanted users to download this app with out using Wifi on the iPhone. The current limit to do this on iPhone is around 10MB. I solved this problem by compressing the individual databases using gzip and extracting them when the user launches the app.

The total extraction takes less than 5 seconds and extraction only happens the firs time.

The final product is around 9MB. Check it out at the App Store
