Agile Software Development Methodology
Agile Software Development is a methodology followed in software
development. In Agile software development the requirements and solutions occur
through the various functional experts working towards a common goal. Agile
methodology is based on iterative and incremental development.
In Agile Development the task are
divided into small chunks with short term planning i.e. into iterations. The
iterations are usually of one to four week time frame. All iterations have
individual teams working to complete the task assigned, each team follows
software development life cycle.

Motorola Sues Microsoft over 16 patents...
As if there weren't already enough patent suits related to smartphone technologies, Motorola just announced its widely anticipated countersuit against Microsoft. Its subsidiary Motorola Mobility filed complaints with two US District Courts (Southern District of Florida and Western District of Wisconsin). Motorola already litigates with Apple in those and other courts. According to Motorola, the patents relate to technologies in the fields of operating systems, video codecs, email, instant messaging, object-oriented software architectures, WiFi, and graphical passwords. Motorola claims Windows, the Live messenger, Windows Phone, Outlook and other Microsoft products infringe. Motorola's action is no surprise given that all of the companies sued over patent infringement by Android — with the exception of Google — have already countersued.
Opting classic row modeling or EAV data modeling?
Few of the circumstances are listed below where EAV scores over conventional tables: · The data type of individual attributes varies. Like in above example EAV is used because the requirements vary from client to client like some may want an extra address like added to existing address format. · The categories of data are numerous, growing or fluctuating, but the number of instances (records/rows) within each category is very small. Here, with conventional modeling, the database’s Entity-Relationship Diagram might have hundreds of tables: the tables that contain thousands/ millions of rows/instances are emphasized visually to the same extent as those with very few rows. The latter are candidates for conversion to an EAV representation.

EAV versus Row modeling
Following are main features/downsides EAV has over classic row modeling technique. A row-modeled table is homogeneous. I t will always carry same type of data in contrast to EAV modeled table where this cannot be an issue. The data type of the value column/s in a row-modeled table is pre-determined by the nature of the facts it records. In contrast, in an EAV table, the conceptual data type of a value in a particular row depends on the attribute in that row. A Row modeling technique data increase only in one direction i.e. from Upside-down whereas in EAV data model data increase in both directions i.e. from upside down as well as from left-right.

Dell Stops selling Ubuntu powered PCs Online
Dell has stopped selling consumer PCs preloaded with Ubuntu from its website, and doesn't know when they're coming back. A search for Ubuntu on the Dell UK website returns only one laptop — the Dell Latitude 2100 from the company's business range. Dell insists that it's continuing to sell Ubuntu systems, but only over the phone, and has no idea when — or even if — the Ubuntu PCs will return online. 'We've recently made an effort to simplify our offerings online, by focusing on our most popular bundles and configuration options, based on customer feedback for reduced complexity and a simple, easy purchase experience,' Dell told PC Pro. 'We're also making some changes to our Ubuntu pages, and as a result, they are currently available through our phone-based sales only.' The move comes after Dell put a page on its website advising customers only to go for Ubuntu if they were interested in open-source programming.
Is 'Quadroid' the New 'Wintel'?
Wintel' is the term that for years defined Windows-based computers running Intel chips. Now a similar expression is emerging for smartphones: 'Quadroid,' a term that refers to the Qualcomm chips used inside smartphones running the Android mobile operating system. The term, recently coined in a report by the PRTM consultancy, could catch on, largely because Qualcomm provides 77% of the chips in phones running Google's Android, which is expected to take the No. 2 slot in 2010. And the Quadroid alliance is expected to grow. Like Wintel has for PCs, Quadroid could push down profit margins for smartphone manufacturers, some analysts say. That might seem like a good thing to consumers, but may not be so good for many phone makers.
