Aircraft from Scratch: Kenyan Tinkerer aims to test fly

Posted: 15 Oct 2010 10:01 AM PDT

A Kenyan backyard tinkerer could go on to become the World's second version of the Wright brothers next week. ;)

Gabriel Nderitu, an I.T. worker with no background in aviation or engineering, put together a hand-built airplane and is planning a test run above the city of Kitengala.
In the video below, a rooster crows as Nderitu and some friends work in a dirt yard to put on the airplane's finishing touches.

Nderitu, 42, spent six months doing research on the Internet and about a year building his two-seater plane from scratch. It involves a Toyota engine driving a 74-inch wooden propeller. The engine turns up to 4,000 rpm and works through a reduction belt drive, according to AVWeb, an aviation site.

He is aimed at becoming the Kenya's pioneer in aircraft manufacturing. :) :)

Have a look at him with his super-cool machine i.e. his innovation - the aircraft from scratch.

Ratan TATA donates $50 million to Harvard Business School

Posted: 15 Oct 2010 09:59 AM PDT

Harvard Business School has received a gift of $50 million from Tata Companies, the Sir Dorabji Tata Trust and the Tata Education and Development Trust, philanthropic entities of India's Tata Group. A conglomerate founded in 1868, the Tata Group owns 28 publicly listed enterprises across seven business sectors that have a combined market capitalization of $80 billion.

The gift, the largest from an international donor in the School's 102-year history, will fund a new academic and residential building on the HBS campus in Boston for participants in the School's broad portfolio of Executive Education programs. The School hopes to break ground for the building, which will be named Tata Hall, next spring.

Ratan Tata, the Chairman of Tata Sons Ltd. since 1991, attended the School's Advanced Management Program—one of three comprehensive leadership programs offered by HBS Executive Education—in 1975. He received the School's highest honor, the Alumni Achievement Award, in 1995.

"The Harvard Business School is the preeminent place to be exposed to the world's best thinking on management and leadership, and we are pleased that this gift will support the School's educational mission to mold the next generation of global business leaders," said Mr Tata.

President Drew Gilpin Faust added: "Ratan Tata knows firsthand the transformative educational opportunities offered through Harvard Business School's Executive Education programs. Thanks to this generous gift, HBS will be able to expand its already robust offerings in Executive Education, deepening ties with leaders across the country and around the globe."

German Engineers designed capsule helps free Chilean miners

Posted: 15 Oct 2010 09:48 AM PDT

Engineers from had developed a device that could be dropped into a small borehole and lowered and raised quickly and repeatedly.

The system that was developed, the Dahlbusch Bomb, had a length of 2.5m and a diameter of 38.5cm and has been deployed numerous times, notably in 1963 when it was used to rescue 11 miners trapped at 58m in the Lengede iron ore mine in Germany.

Miners trapped for 69 days following the collapse of a shaft at Chile's San Jose mine are today being transported from their subterranean ordeal in a capsule that has its origins in Germany.

So far, 15 of the 33 miners have made the 15-minute journey in the Phoenix II escape pod, one of three designed for the operation by NASA and Chilean Navy engineers.
:happy:

Chinese Hackers steal South Korean Secrets

Posted: 15 Oct 2010 09:44 AM PDT

Hackers in China have stolen secrets on South Korea's defence and foreign affairs by using bogus emails claiming to come from Seoul officials and diplomats, the intelligence agency said Friday.

The National Intelligence Service uncovered the hacking early this year and warned government offices about the danger of such emails, a spokesman told AFP.
Hackers sent emails in the names of South Korean diplomats, presidential aides and other people familiar to Seoul officials.
Attached files containing viruses were disguised as important documents, such as analyses on North Korea's economy.

When a recipient clicked on the attachment, the virus started downloading documents in his or her computer, the spokesman said.

Swiss Engineers build the Longest Tunnel

Posted: 15 Oct 2010 09:40 AM PDT

They smashed through the last stretch of rock Friday to create the world's longest tunnel. This project that has been 60 years in the making.

A gigantic drilling machine broke the remaining wall 8,200 feet (2,500 meters) below the imposing Piz Vatgira peak in the Gotthard massif several minutes ahead of schedule Friday afternoon.

Trumpets sounded, cheers reverberated and even burly workers wiped away tears as foreman Eduard Baer lifted a statue of Saint Barbara — the patron saint of miners — through a small hole in the enormous drilling machine thousands of feet (meters) underground in central Switzerland.

At that moment, a 35.4-mile (57-kilometer) tunnel was born, and the Alpine nation reclaimed the record from Japan's Seikan Tunnel.
Television stations across Europe showed the event live. See the video:



First conceived in 1947 by engineer Eduard Gruner, it will allow millions of tons of goods that are currently transported through the Alps on heavy trucks to be shifted onto the rails, particularly on the economically important link between the Dutch port of Rotterdam and Italy's Mediterranean port of Genoa.
The tunnel also aims to reduce the damage that heavy trucks are inflicting on Switzerland's pristine Alpine landscape.

Now THIS is real engineering. BIG & AWESOME :cean:

Facebook keeps deleted photos for years

Posted: 15 Oct 2010 09:31 AM PDT

Facebook has been slammed for keeping photos deleted by users for as long as 30 months.

It has admitted it had been keeping deleted photos for a 'limited' amount of time. However, users who have kept the direct link to photos that were originally uploaded on Facebook have been able to still gain access to them months, even years after deletion.

Source: Sydney Morning Herald

The revelation comes as encryption expert and author Bruce Schneier slammed the site at the RSA Conference in London, saying social networking companies were deliberately killing privacy for commercial gain.

The Facebook photo matter centres on what is known as a content delivery network, or content distribution network (CDN), which stores multiple copies of content on servers around the globe.

Facebook uses such a delivery method when you upload a photo to the site. However, when you delete your photos from the site, despite them being removed from view, if you still have the image's direct URL it may still be accessible for a period of time after its removal.

The question is, how long will people take to understand that uploading photos is not safe? :mad:

Google Sky and Slooh bringing live Astronomy

Posted: 15 Oct 2010 09:14 AM PDT

For some time now, Google Sky (See here: Google Sky)
has enabled users to view a wide range of imagery from high-level sources like the Hubble Telescope, NASA satellites, and the Sloan Digital Sky Survey.

But the service has never provided a method for users to view community-created imagery, or to participate in the viewing of live events like eclipses.
Until now.

On Friday, Google announced a partnership with Slooh, a New York company that offers the public Internet-based access to a global network of observatories, and a diverse and constantly growing collection of telescopic viewing and photography "missions."

If you haven't heard of Google Sky, See this video:

Mobile Apps contest to win an ipad/join Bell Labs India

Posted: 14 Oct 2010 10:01 PM PDT


Ready for a job that lets you innovate and build cool new applications?
Desire to win an ipad?
[IMG]file:///D:/DOCUME%7E1/skannapp/LOCALS%7E1/Temp/msohtml1/04/clip_image004.gif[/IMG]


We are looking for research engineers who are passionate about building novel, attractive and scalable applications/services on mobile hand-sets.

We want our selection process to be fun, intuitive and also reflect our work culture. So the first phase is a Mobile Apps contest to shortlist the right talent! This contest is a forum to express your creativity and skills and in the process win an opportunity to win an ipad and also join Bell labs, India as a Research engineer.

Please find the JD and interview process after the contest info.

Contest info:

There are three Mobile App options. You can select one of these.

For detailed guidelines, go to Bell labs, India


1. Build a '1-click' photo-sharing app

100s of Millions of mobile users in India have phones with a camera, but is there a simple app that lets people share photos fast with their friends easily? (MMS is too expensive, slow for most, and how many have Picasa/Flickr accounts?). Design an app that makes it happen!


2. Build a configurable-privacy enabled 'nearby' friend finder app

Several location-based friend finder apps are already there in the app market. We want you to design/build an app with similar functionality, but the differentiator being that the app should involve minimal revelation of location information of mobile users. Location information should be revealed to a friend, only when the friend is within a configurable 'vicinity zone'. You get brownie points, if you can design techniques by which such functionality (or an approximation) can be realized, without the back-end server getting to know the GPS coordinates of the mobile users.

3. Build a mobile lifelog app
The concept of lifelogging, i.e. recording, archiving and visualizing all information in one's life has been around for some time. We want you to build a mobile lifelog app that passively monitors and collects the traces of call-logs, sms, images/videos (captured from the phone) and GPS coordinates in the form of events and reports them back to a back-end server. The server provides Web APIs/service to graphically visualize this information. The server also facilitates posting some of these interesting events on Facebook as wall posts.

Submission deadline:

Contest closes by Dec 15th, 2010. We evaluate submissions on a first come first serve basis. So send in your submissions as soon as you are ready.

To kick start this process, please send an email to blrindia@alcatel-lucent.com with the following details:-
1) Name, phone number
2) Current affiliation (company/university)
3) Current role
4) Tentative choice of app
5) Tentative submission date

The subject line should be 'Registration: Bell labs India Mobile Apps contest'

Interview process:

·Mail your CV and code to Bell labs,India(blrindia@alcatel-lucent.com) with 'Bell labs India Mobile Apps contest' in the subject line. Entries without this subject line will be dis-qualified
·If selected, be prepared for a telecon interview on coding and design choices
·The shortlisted candidates will be asked to appear for a face to face interview in our Bangalore office
·The first prize is an ipad. People who come second and third will win cool prizes too! Winners and top candidates will be evaluated for a position at Bell Labs, India as a Research Engineer.

Job Description:
We are looking for highly motivated, high-caliber software engineers to become part of the advanced prototyping group of the Applications Department of Bell Labs India, Alcatel-Lucent. The charter of the advanced prototyping group is to work with researchers in building systems that take research ideas from a conception stage to products that are ready to be launched in the market. Given that the Applications Department's focus is in developing innovative services and applications for emerging markets where the mobile handset is a predominant device, we are seeking individuals who have expertise in building mobile applications served by scalable back-end systems.
