hacking

Hacker is a clever programmer. A "good hack" is a clever solution to a programming problem and "hacking" is the act of doing it

Who is Kevin Mitnick? The picture that emerged after his arrest in Raleigh, N.C. last February was of a 31-year old computer programmer, who had been given a number of chances to get his life together but each time was seduced back to the dark side of the computer world. Kevin David Mitnick reached adolescence in suburban Los Angeles in the late 1970s, the same time the personal computer industry was exploding beyond its hobbyist roots. More on Kevin Mitnick

Fadia was educated at Delhi Public School. He started a website called "HackingTruths", which he claims was judged as the "second best hacking site in the world by the FBI". He claims that when he was 14, he trashed the front page of an Indian magazine's website. He then sent an e-mail to the editor confessing to the hack, suggesting counter measures. At 15, his book on Ethical Hacking made him the youngest author to be published by Macmillan India. More on Ankit Fadia

India stand at fourth place in wind power

Hello friends

this post was originally posted at http://electro-scope.blogspot.com/ by Mr N R Meel and with his due permission is being posted here.

Wind power is the conversion of wind energy into more useful forms, usually electricity, using wind turbines. At the end of 2006, worldwide capacity of wind-powered generators was 74,223megawatts; although it currently produces just over 1% of world-wide electricity use. it accounts for approximately 20% of electricity use in Denmark, 9% in Spain, and 7% in Germany.Globally, wind power generation more than quadrupled between 2000 and 2006.

Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator. In windmills (a much older technology), wind energy is used to turn mechanical machinery to do physical work, such as crushing grain or pumping water.

Wind energy is plentiful, renewable, widely distributed, clean, and reduces toxic atmospheric and green house emmission if used to replace fossil-fuel-derived electricity. The intermittency of wind seldom creates problems when using wind power at low to moderate penetration levels.
India ranks 4th in the world with a total wind power capacity of 6,270 MW in 2006. Wind power generates 3% of all electricity produced in India. The World Wind Energy Conference in New Delhi in November 2006 has given additional impetus to the Indian wind industry. The windfarm near Muppandal, India, provides an impoverished village with energy for work.India-based Suzlon Energy is one of the world's largest wind turbine manufacturers.

Mechatronics

Mechatronics is a portmanteau word – a fusion of ‘mechanics’ and ‘electronis’.it first originated in the 1980s in japan . it was used to denote the combination of technologies used to produce industrial robots. Mechatronics can be defined as a synergetic integration of mechanical ,electrical,electronics and computer science and IT disciplines to produce products or systems.computers,disk drives,fax machines,VCR,washing machines robots are examples of these systems.

Experts are of the opinion that future mechanical,electrical ,computer science and IT have to deal with mechatronics or face the possibility of becoming out dated. Mechatronics are now a days used in manufacture of cars by use of electronic engine management systems ,collision detection,global positioning system etc.Research and development potential in mechatronics includes areas such as space technology, especially in the wake use of robots for space exploration.

Another variant of mechatronics is boimechatronics which is an applied interdisciplinary science that aims to integrate mechanical elements in human body,both for therapeutic uses and for augmentation of existing abilities.is includes aspectsof biology ,mechanics and electronics.

state level technical symposium in bio informatics

hi friends,
I am very glad to inform you people that there is a state level technical symposium "BIOSILICON" held in bharath university,chennai on 12th oct.any interested candidate can paticipate and present their paper and all the participants will be awarded with the participation certificate.if you are interested plz reply me back to ksowmya20@gmail.com for the topics. Hoping for the positive reply.

Civil Engg.

Civil Engineering is a profession which caters to the civic needs of humans such as shelter, water, transportation, etc. It essentially deals with design, construction and maintenance of the systems which cater to the human needs stated above. Some of these are buildings, bridges, roads, dams, towers, etc.

Civil Engineering can broadly be defined into the following divisions

1. Structural Engineering: One of the most interesting fields of civil engg. (according to me) deals with the design of structures. Structural engineers may work in tandem with architects in the design process. Nowadays the design is done mostly in softwares but still the role of a structural designer cannot be underestimated.

2. Building Technology and Construction Management: This involves the actual execution process. After software, construction sector is the one which has been having the maximum boom in the last five years. Construction is no more only brick and mortar. It requires high level of managerial skills along with the basic civil engg. Knowledge.

3. Geotechnical Engineering: Geotechnical engineers deal with the soil as the name suggests. They are involved in design and construction of foundation systems. Nowadays there are companies dedicated only for Geotech works as the foundation systems are getting more and more complicated.

4. Transportation Engineering: It can again be divided into two categories one which deals with the design and construction of roads and other which deals with the design of road networks (they decide where to have a flyover, signal timings etc.). If you want to go to US for higher studies this is the field to go into. There is lot of research going on in US in transportation engineering and you can funding pretty easily.

5.Environmental and Water resources Engineering: This division deals with dams, irrigation projects, drinking water supply, waste water treatment, etc. Environmental Engg is one more option for students who want to go abroad for further studies. There is a lot of funding in environmental engg not only in US but also in Europe.

Montevina: The NExT Centrino to be launched by Intel

Intel had been waiting for the right time to unravel it’s brand new mobile platform. Intel calls it the Montevina platform. Montevina is the fifth generation Centrino platform, on which you not only get integrated WiMAX capabilities, but also benefit from chip-level support for both the upcoming laser-disc technologies, Blu-Ray and HD DVD. This almost aggregates the ongoing “format war”, since dual support for the formats is being preferred by an increasing number of manufacturers. It is good for the consumers, but Sony will be disappointed as this is going to nullify their efforts to make Blu-Ray the monarch.

Displayed at the Intel Developer Forum for the first time, the Montevina mobile computing platform has been specially designed to take over the company’s highly successful Santa Rosa notebook architecture. Montevina will host the new 45nm Penryn processor architecture, which means integrated WiMAX capabilities but could not opt for one choice in the ongoing high definition format war. Consumers will win in the end with this approach, as they will be able to watch movies that are exclusive to either format, while Toshiba and Sony sit down, bubbling in a corner.

This is a very appreciable effort from the Intel factories, since it is a chip manufacturer and to offer such support for both disc formats is simply a burden as the two formats commonly share the same codecs: H.264, VC9, and MPEG-2. It is this onboard support for either of the two platform that makes system makers choose either HD DVD or Blu-ray capability, or even both.

Seen overall, this HD format hype shall be easily overtaken by the on-board WiMax support that Montevina caters to.
