I’m still getting Semantic Web topic suggestions emails from MS/PhD students however, I’m not working on Semantic Web directly, for some reasons I changed my main focus to Computer Networks and Networking related topics.

Currently, carrying out an NFC (Near Field Communication) R&D project supported by Minister of Science, Industry and Technology. My PhD thesis supposed to be on NFC related subject, I have some ideas on Health Care Systems and NFC but not finalized yet.

Also, trying to finish a paper for ICNFI 2012.

About iPhone 4S Sim Failure & Batter Usage

admin — Thu, 08 Dec 2011 14:55:40 +0000

There are hundreds of posts & thousands of page views about iPhone 4S Batter Life at Apple Support Forums. A few days, I’ve faced same problems a few days like I had no sim and sim failure errors, network losses and a few hours with full charge ! It seems problem is related directly with Apple but still there are solutions, at least two things worked for me;

1 – Changing SIM card with new one ( currently 64Kb micro sim ) solved network loss and sim failure errors.
2 – Turning off a few location based services;

Settings -> Location Services On -> Siri Off
Settings -> Location Services -> System Services -> Cell Network Search & Compass Calibration is On and everything else Off.

The result is surprising, my iphone batter is 70 % with 1 day standby and 1 hour usage.

Update

You can still have 2 days standby with a few hours usage.

New iPhone’s camera is much better than expected, still I’m playing with camera. So, Its too early to evaluate and compare with other devices. What I want is to share two photos taken through this device.

Internet of Things

Internet of Things(IoT) is an interesting topic in computer science. The idea behind IoT is, enabling everyday objects in the Internet through RFID tags, sensors, mobile devices …etc. There is an interesting study made by Latitude Labs with kids and their expectations from Internet. Sum results from study;

RXTX PortInUseException on Mac OSX

admin — Sat, 26 Nov 2011 11:47:35 +0000

This was my first serial programming experience on Mac OS X with Java and it was painful. There is no official library for Java for writing/reading from serial interface. Open source libraries available but those depends on OS, and OS architecture and java versions. After required libs installed, I had to get list of all port on my mac using rxtx however, had to deal with with PortInUseException while opening a port. Thanks to this guy; solution is to set up a folder and required permissions at location /var/lock, then everything went very well.

After a few years I returned back to java, it still same java nothing much here I can handle it.

A Fresh Start

admin — Wed, 02 Nov 2011 14:54:00 +0000

I haven’t touch my blog for months and It doesn’t seem I can write long posts every day or week but at least I try to share things like videos, links …etc.

Using godaddy or an other hosting company for a power user, doesn’t work. I have to move a private server, ordered and set it up within two days. So, I can say this is a fresh start and I hope I can continue on writing regularly.

About Android

admin — Fri, 28 Jan 2011 11:56:37 +0000

Finally, I had a chance to play with Android SDK and develop something. Something called Istanbul Guide, yes the Android version of my first iPhone App. It’s available both in Android Market and Community Markets for free to download.

I’m interested in Android because it’s open, it’s linux, it’s java … etc. If you look at end user point, no doubt that iPhone is the killer. iOS is its limited, there are boundaries and rules you have to obey. I want freedom. Why? Recently started a new project (still in design phase), which aims to make disabled people’ life easier. Resulted application supposed to modify underling operating system to replace existing user-device interaction like replacing standard keypad … etc. That’s impossible for iOS but not in Android.

I’ll be still working on iOS but I believe innovation happens when it’s open.
