JBenchmark - Benchmark your J2ME mobile


Benchmarking is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. It's more popular among computer enthusiasts as a method of comparing there workhorse with others. B-) B-) 3DMark and PCMark by Futuremark are popular benchmarking tools for PCs.
So why not have your mobile also benchmarked? Well now you can benchmark J2ME enabled mobiles as well. JBenckmark suite, developed by Kishonti Informatics has few benchmark tools to measure the CPU performance, Graphic performance and Multimedia capabilities of the device.
I have used JBenchmarkACE - ARM CPU Estimator and the result was a ARM9 Family processor running at 105MHz for my LG KU250. So how about yours?

#132# - MobileCert


Few Weeks agoThe Sri Lanka Telecommunication Regulatory Commission (TRC) has issued a new set of guidelines in using mobile and CDMA phones. This step was taken to avert irregularities and illegal activities while minimizing threats to national security created by the irresponsible use of telephones. Under this the mobile operators in Sri Lanka was requested to implement a method to issue a certificate so that it can be validated that whether the registered owner is using the particular connection.

Few days ago Dialog has implemented this and with effect from today Mobitel is also activated this feature. Now issuing code #132# in a mobile phone provids a message with the registerd user name, ID and mobile number. So it is expected that the armed forces and other security institutions will start to inspect this in near future. So the user's are adviced to make sure that they use the connections with regulations set forth to avoid unwanted troubles.

No more Project Hoshimi Invitationals in Future :-(


Microsoft has decided to discontinue Project Hoshimi invitational which is a great strategic programming competition, from future Imagine Cup competitions - the world’s premier student technology competition. It is not known officially what was the reason to remove one of the most popular invitational from the competition. But there was rumors that the reason is there is not direct connection with the theme of the competitions in later years than it was first introduced where the theme was about health and eventually media was no longer interested in this invitational.

However the Project Hoshimi Lead Manager desides to continue support the project personally for the educational benificial of the student community.

ODF plugin for MS Office


The OpenDocument format (ODF) is a free and open file format for electronic office documents, such as spreadsheets, presentations and word processing documents. ODF if primarily implemented by office suite and the main file format of the respective product.

This file format was popular among linux (Primarily open source developers as well) fans but the pain was using these documents under a Windows PC having MS Office. MS Office does not natively support OpenDocument currently. However you can download ODF add in for Microsoft Office at And the MS Office will natively support the ODF format from SP2 of Office 2007 onwards.

Long Filename Problem in LG KU250


There is a bug in the LG KU250 firmware (at least as of software version 10d) that if you transfer a file with a long file name which is longer than that the phone supports the file simply disappears but the space is occupied from the common memory of the phone. (This problem may not occur if you used external MicroSD card.)

The only option appear to be to restore the firmware into default state. The reset function as well as clear all memory function doesn't solve the problem. A factory reset code wasn't available to be known at the time of writing.

Note: LG KU250 is The winning handset in the GSMA's "3G for All" program 2007.
