Smallest Plane:

The BD-5 Micro is a series of small, single-seat homebuilt aircraft created in the late 1960s by US aircraft designer Jim Bede and introduced to the market primarily in "kit" form by the now-defunct Bede Aircraft Corporation in the early 1970s.

The BD-5 has a small, streamlined fuselage holding its semi-reclined pilot under a large canopy, with the engine installed in a compartment in the middle of the fuselage, and a propeller or jet engine in the BD-5J variant, mounted immediately to the rear of the cockpit. The combination of fighter-like looks and relatively low cost led to the BD-5 selling over 5,000 kits or plans, with approximately 12,000 orders being taken for a proposed factory-built FAA certified version.[1] However, few of the kit versions were actually completed due to the company's bankruptcy in the mid-1970s, and none of the factory built "D" models produced, brought on by the failure to deliver a reliable engine for the design.

In total, only a few hundred BD-5 kits were completed, although many of these are still being flown today. The BD-5J version holds the record for the world's lightest jet aircraft, weighing only 358.8 lb (162.7 kg).

Common Forum / The World's Tallest Hotel

The world's tallest hotel opens its doors in Hong Kong

It offers a bird's eye view of one of the most spectacular skylines in the world. These come in the form of six restaurants, a sky-high spa with floor-to-ceiling windows and an indoor infinity pool overlooking the iconic harbour.

The hotel's facilities include state-of-the-art technology including WiFi, iPod docking stations, Blu-ray DVD players and flat screen TVs.

There are three restaurants on the 102nd floor, including Tin Lung Heen, which is a Chinese restaurant serving refined Cantonese cuisine; Tosca, an Italian restaurant which offers Southern Italian cuisine and the very stylish The Lounge & Bar with fire pits and open kitchens.

In addition, there is a chocolate-themed lounge named The Chocolate Library on 103rd floor and a stylish patisserie located on 9th floor.

Managers say the jewel in the crown is Ozone, located on the hotel's 118th floor.

It offers contemporary Asian tapas and signature cocktails to a backdrop of incredible views as well as the chance to drink on the world's highest al fresco terrace.

The hotel has an ESPA on site which is located on the 116th floor.

One Student One Laptop / Re: i want back my laptop

I did not heard anybody complain about the laptop before. The burning may be due to many reasons. The socket you plugged in the charger, electrical disturbance from the main power line to your home. Mr. Mamun already stated many reasons of burning. I hope everything is alright with your laptop.

Pharmacy / Oldest Living Trees
« on: November 17, 2011, 06:01:09 PM »
By far the tallest living things are redwood trees. Relatives of the sequoia, they can soar taller than a 36-storey building. Like all trees, redwoods and sequoias continue to grow as long as they are alive. Thus, the longer a tree lives, the taller and wider it becomes.

Except for men who cut them down for timber or earthquakes, fires and lightning—redwoods and sequoias have few enemies. Scientists have researched the redwoods carefully, and have not found even one that has died of old age, sickness, or insect attack. This latter is a common problem of trees. The Dutch elm disease killed and ruined thousands of the beautiful shade trees of many American small towns.

It is significant therefore that no redwood tree has been found older than about 4,000 years. There are, though, many sequoias and redwoods in the 3,000 year-old range. The most famous sequoia tree, ‘General Sherman’, located in the Sequoia National Park in California, is about as high as a 27-storey building. It has been around for something like 4,000 years. To support its height, its immense trunk is so large that 17 men stretching out their arms could just about reach around it. This single tree contains enough wood to construct 100 modern houses.

But as tall and old as many sequoias are, they are not the oldest tree. A bristlecone pine in the White Mountains of California has this honour. It is more than 4,000 years old.

As trees such as the bristlecone pines and the redwoods are still living after 4,000 years or more, and seem impervious to the normal problems of trees, it is conceivable that they could live another 4,000 years or longer.


Open Source Forum / World's Fastest Supercomputer-Mira
« on: November 17, 2011, 05:34:24 PM »
Say hello to the Blue Gene/Q, or if you're looking for something a bit less intimidating, "Mira." That's IBM's latest and greatest concoction, a ten-petaflop supercomputer capable of running programs at ten quadrillion calculations a second. Hard to say who'd win between Mira and Watson, of course, but there's absolutely no question who'd come out on top if Mira were pitted against her predecessor Intrepid (hint: Mira's 20x faster). To put this all in perspective, IBM's chiming in with this:

    "If every man, woman and child in the United States performed one calculation each second, it would take them almost a year to do as many calculations as Mira will do in one second."

Mira's next stop is at the US Department of Energy's Argonne National Laboratory, where it'll be used to tackle 16 projects in particular that were drawn from a pool of proposals to gain access to her capabilities. We're told that these include a range of initiatives -- from reducing energy inefficiencies in transportation and developing advanced engine designs to spurring advances in energy technologies -- and in time, it could lead to exascale-class computers "that will be faster than petascale-class computers by a factor of a thousand." And here we are getting excited about a 5GHz Core i7.
