Ever since its entry into the mobile handset industry Sony Ericson has established itself as one of the leading brand both in style and innovation. The firm is a global provider of cellular multimedia devices, along with feature-rich mobile phones, accessories and PC cards. Sony Ericson’s W910i Walkman® has won the award of Best Handset at the GSM Association’s 13th Global Mobile Awards 2008 for its magnificent definition of music. It’s just few months that Sony Ericsson W350 has also been launched and the kind of response it has got is really amazing. People have loved its sound quality.

The cell phone weighs 80g with 1.9 inch screen. As others it supports Polyphonic, MP3, and AAC ringtones. It also offers the feature of Photo call. The W350 supports M2 i.e. Memory Stick Micro memory cards. It provides data transfer facility with GPRS at18 kbps, Bluetooth and of course the USB port. You can enjoy SMS, EMS, MMS, Email, Instant Messaging too. Its browser is quite advanced and supports WAP 2.0/xHTML, HTML (NetFront), RSS reader. Its also has Camera with 1.3 Mega Pixel resolution, FM, image viewer, walkman player and much more for your leisure. Its battery life is quite good and most interestingly, it is free with an AT&T contract. Though there are some really good handsets with similar features in the market from other companies but its cheap price with tiny and weightless design definitely puts it in the preference list of buyer.

Data Mining means extracting or mining the knowledge from the voluminous data. It is also sometimes referred as knowledge mining from databases, knowledge extraction, data or pattern analysis, data archaeology, and data dredging. Many people believe that Data Mining and Knowledge Data Discovery i.e. KDD are same. Knowledge Data Discovery and Data Mining are vast topic and also very interesting subject in Computer Science and Engineering here at MANIT Bhopal. Working of search engines like Google also utilizes these concepts Data Mining. It can be a very good research topic especially for those who have good hold in DBMS. Knowledge Discovery involves sequence of processes. They are as follows:

• Data Cleaning: This step involves removal of noisy and irrelevant data.
• Data Integration: It involves the process of combining multiple data sources
• Data Selection: In this step relevant data are retrieved from the Database so that they can be analyzed.
• Data Transformation: This is very crucial step in which the selected data for analysis is further used and transformed into desired and appropriate form. Particularly in multidimensional database the irrelevant dimension is removed.
• Pattern Evaluation: Here we identify to identify the truly interesting patterns representing knowledge based on some interestingness measures
• Knowledge Presentation: This is the final step in which the mined knowledge is represented to the end user in the form of bar graphs or spread sheets etc.

Usually the first two steps are known as Data Preprocessing when combined. Though there are various other concepts which is needed to understand the complete process nicely such are Data Warehousing, OLAP Technology, various algorithms for analyzing the data etc. But the space will not suffice due to vastness of the topic. If you want any help in above concepts please leave the comment. Here at NIT-Bhopal we are recommended the book of author named Kamber for this subject. The book is vast and interesting but requires good knowledge about the DBMS concepts.

People who are curious about the technology might know about the Android. Android is a stack of software developed by the Google especially for Mobile devices. Android includes an OS which enables the application developers to work with the Java language. Though, only its Beta version has been released that can be downloaded here. But making its first grand and much anticipated presence in the market it is going to be released embedded into new G1 phones from T-Mobile’s later this month. The phone is believed to have features like iPhone. It is another touchscreen mobile phone with OS in it. However some reviewers have doubted on whether it can give competition to Apple’s iPhone. There is lot of buzz among the reviewers about the features that the G1 is going to offer. According to a review given by Nancy Gohring, IDG News Service, G1 is far behind the level of iPhone as far its hardware is concerned. Hardware design of G1 may not lure the buyers. But the Google’s Android might have some role in attracting the users. According to the reviewer the G1 phone has poor picture quality, inferior camera and awkward positioning of some keys. However the Keyboard of G1 is better. Android provides some really cool and new features to the users. Gmail and Google users would be benefitted due to extra support for these applications and services. But users with different choice like Yahoo mail may have to suffer a bit. You can read the full article called The G1 Is No IPhone, but Android Has Promise at the link given.

Though T-Mobile’s G1 may be compared to the iPhone and Nokia’s products but the current status of Android says it is still in developing phase as most of the Google products. So it would be interesting to see how they respond to the critics and the needs of users.

On 8^th October 2008 I wrote about Google email archiving service extends for up to decade. I don’t know what would be the response of the users and enterprises on this step but recent comment of GNU founder Richard Stallman on cloud computing, which is somewhat similar concept to archiving services, has really raised some questions over the reliability and security of the data. According to him Cloud computing is a trap as quoted in an article at Gaurdian.co.uk. Before telling you about what he said, let me tell you about the concept of cloud computing. Cloud here means “The network of servers” and hence the cloud computing is the supercomputing-level power to user. Cloud Computing is also known as On Demand Computing. The cloud or The Network of Servers are used to manage the distributed database in which the components of program are stored in thousands of computers. Actually Cloud Computing uses the concept of using multiple computers which can be possibly Computers or UNIX workstations, multiple storage devices, and redundant interconnections, to form what gives the user an illusion of a single highly available system. This concept is also called the Cluster Computing. It is used for load balancing the traffic and ensuring the high availability.Moreover, Parallel Processing has enabled the program to run with less time complexity by processing the program instructions dividing them among multiple processors. Hence due to both cluster computing and parallel processing vast processing power is available.

Thus now vendors like IBM, Amazon etc. allow users and enterprises to use the services and storage whenever and wherever they need. Users are charged for these services depending upon the server utilization, processing power used or bandwidth consumed. Google Apps, Maps and Gmail are all based on this the cloud computing. That is why it is likely that one day everyone will rely on the remote access of data. Numbers of organizations are already offering free Web services in the cloud. According to the Richard Stallman using such services is “worse than stupidity”. He said that cloud computing was simply a trap aimed at forcing more people to buy into locked, proprietary systems that would cost them more and more over time.

The article also mentioned that the growing number of people storing information on internet-accessible servers rather than on their own machines has become a core part of the rise of Web 2.0 applications. Millions of people now upload personal data such as emails, photographs and, increasingly, their work, to sites owned by companies such as Google. Stallman added that that using such web applications to do your computing makes you lose control. You are getting defenseless as you are you are putting your programs and data in the hands of whoever developed that software. Now being user you have to decide whether you can risk the integrity of your data.
