Jazz is an IBM Rational initiative to help make software delivery teams more effective by making it more collaborative, productive and transparent, through integration of information and talks across the phases of the software lifecycle. [1]
Jazz is an open platform designed to support any participant who wants to improve the software lifecycle and break down. [1]
The Jazz is composed of three elements:
The main objective is to provide a frictionless work environment that helps team collaborate, innovate, and create great software. Key points are fundamental improvements in team collaboration, automation, and reporting across the software lifecycle. [1]
The amount of information available on the Internet is currently growing at an incredible rate. However, the lack of efficient indexing is still a major barrier to effective information retrieval on the web. A lot of research has gone into developing retrieval systems on the web. Despite all that, using current indexing techniques, it has been reliably estimated that on average only 30% of the returned items are relevant to the user’s need, and that 70% of all relevant items in the collection are never returned. These results are far from ideal considering the user is still presented with thousands of documents pertaining to a keyword query in milliseconds. Existing indexing techniques, mainly used by search engines, are keyword based. In other words, each document is represented by a set of meaningful terms (also called descriptors or keywords) that are believed to express its content. The major drawback to keyword based methods is that they only use a small amount of the information associated with a document as the basis for relevance decisions. As a consequence, irrelevant information that uses a certain word in a different context might be retrieved or information where different words about the desired content are used might be missed. To achieve better performance, more semantic information about the documents needs to be captured. Some attempts at improving the traditional techniques using Natural Language Processing, logic and document clustering have offered some improvements. Some of the KMRC members have supervised PhD students who worked on the development new content-based indexing and retrieval algorithms (such as RST-Index) which uses computational and linguistic techniques such as Rhetorical Structure Theory (RST) and Natural Language Understanding (NLU) and there is still a need for PhD students to extend the research on content-based indexing and retrieval to improve what has been achieved so far.
mysqldump tool provide facility to backup MySQL databases. It creates *.sql file with DROP, CREATE and INSERT statements. There are number of keys, which can be used to create backup of database(s).
Details of all keys can be checked using command
bash: # mysqldump --help
bash: # mysqldump -u root -p[root_password] [database_name] > filename.sql
bash: # mysql -u root -p[root_password] [database_name] < filename.sql
A frame may have up to 4 Addresses which depends on the ToDS and FromDS bits in the Control Field as mentioned below:
Address1: is Recipient Address, like BSS station is the immediate recipient of the packet. If ToDs is set then this is AP address and if ToDs is not set then this is address of the end station. Continue reading
