New Fields of Application for Bitcoin Protocol

Posted on by

Blockstream is working on new technology capable of using the Bitcoin protocol in order to secure any form of online value transfer and organise the safekeeping of digital ledger assets.

Since it was set up in 2009, Bitcoin has become a highly powerful information storage network, capable of storing thousands of gigabytes of data by using miners, which approve transactions and host the relevant information on their servers. The 13.5million bitcoins circulating on the network today have a total estimated value of $4.7billion, in spite of the volatility of this crypto-currency and the technical deficiencies from which it suffers major reasons why Bitcoin has not expanded further around the world.

The crucial innovative idea that the Bitcoin originators came up with is the creation of what is known as a blockchain, which records transactions on the network, the information being distributed across multiple servers all over the globe. Another startup called Genecoin has recently embarked on a mission to store individual peoples DNA on the same network and thus enable them to ensure their digital immortality. Meanwhile the blockchain approach has also generated sidechains otherwise known as orphan blocks, which are created when two main blocks are generated within too short a time-span.Now Montreal- and San Francisco-based Blockstream is looking to exploit these sidechains to develop new functionality. The startup team have developed software capable of ensuring safe transfer of bitcoins or other digital ledger assets from the blockchain to pegged sidechains and back again as required. Cryptographic expert Adam Back, who co-founded Blockstream, explains that it will be feasible to use the pegged sidechains to create instantaneous transactions. Bitcoin transfers can currently take as long as ten minutes to confirm, which is rather a long time compared with other means of purchasing goods and services.

The major innovation in Blockstreams proposals is the creation of a two-way peg, a tool enabling the transfer of bitcoins of other crypto-assets between all the various chains in the network. The new applications that are likely to spring from this approach includesmart contracts i.e. using an IT protocol to establish/authenticate a contract without the need for intermediation by lawyers for trading in such financial instruments as equities, bonds and derivatives, plus smart physical property trading. Gavin Anderson, an engineer working at the Bitcoin Foundation, reckons this innovation will enable a range of services to be provided, underpinned by the trustless security of the Bitcoin network.

Blockstream has just raised US$21 million in capital from investors including LinkedIn founder Reid Hoffman and Vinod Koshla, who founded SunMicrosystems, and is currently working on the first prototype sidechains, with a view to launching the technology during 2015 in partnership with other interested companies.

In a recent paper, the Blockstream team purport to demonstrate how the Bitcoin network could prove to be the most appropriate secure system for authenticating many different types of contract, enabling distributed applications and avoiding the need for third-party intermediation. Working along similar lines, Ethereum, a startup founded by Vitalik Buterin, provides an open-source platform that enables entrepreneurs and developers to build new, decentralised applications based on the blockchain.

Bill Haley & His Comets – Wikipedia, the free encyclopedia

Bill Haley & His Comets

Bill Haley & His Comets, c. 1955 Left to right: Joey D'Ambrosio, Dick Richards in the back row, Bill Haley

Bill Haley & His Comets was an American rock and roll band that was founded in 1952 and continued until Haley's death in 1981. The band, also known by the names Bill Haley and the Comets and Bill Haley's Comets (and variations thereof), was the earliest group of white musicians to bring rock and roll to the attention of white America and the rest of the world. From late 1954 to late 1956, the group placed nine singles in the Top 20, one of those a number one and three more in the Top Ten.[1]

Bandleader Bill Haley had previously been a country music performer; after recording a country and western-styled version of "Rocket 88", a rhythm and blues song, he changed musical direction to a new sound which came to be called rock and roll.

Although several members of the Comets became famous, Bill Haley remained the star. With his spit curl and the band's matching plaid dinner jackets and energetic stage behavior, many fans consider them to be as revolutionary in their time as the Beatles or the Rolling Stones were a decade later.

Following Haley's death, no fewer than seven different groups have existed under the Comets name, all claiming (with varying degrees of authority) to be the official continuation of Haley's group. As of the end of 2014, four such groups were still performing in the United States and internationally.

In the mid-1940s, Bill Haley performed with the Down Homers and formed a group called the Four Aces of Western Swing. The group that later became the Comets initially formed as Bill Haley and the Saddlemen c. 19491952, and performed mostly country and western songs, though occasionally with a bluesy feel. During those years Haley was considered one of the top cowboy yodelers in America. Many Saddlemen recordings would not be released until the 1970s and 1980s, and highlights included romantic ballads such as "Rose of My Heart" and western swing tunes such as "Yodel Your Blues Away". The original members of this group were Haley, pianist and accordion player Johnny Grande and steel guitarist Billy Williamson. Al Thompson was the group's first bass player, followed by Al Rex and Marshall Lytle. During the group's early years, it recorded under several other names, including Johnny Clifton and His String Band and Reno Browne and Her Buckaroos (although Browne, a female matinee idol of the time, did not actually appear on the record).

Haley began his rock and roll career with what is now recognized as a rockabilly style in a cover of "Rocket 88" recorded for the Philadelphia-based Holiday Records label in 1951. It sold well and was followed in 1952 by a cover of a 1940s rhythm and blues song called "Rock the Joint" (this time for Holiday's sister company, Essex Records). Slap-back bass, one identifying characteristic of rockabilly, was used on the Comets' recordings of "Rocket 88", "Rock the Joint", "Rock Around the Clock", and "Shake, Rattle, and Roll".[2] Prior to becoming the Comets, slapback was also used by bassist Al Rex, although to a lesser extent, on "Yodel Your Blues Away".[3] Slap-back bass was a necessity for the group because in its early years (prior to the fall of 1952), it did not feature a stage drummer, so the bass provided percussion in addition to the bass line.

"Rock the Joint" and its immediate followups were released under the increasingly incongruous Saddlemen name. It soon became apparent that a new name was needed to fit the new musical style. A friend of Haley's, making note of the common alternative pronunciation of the name Halley's Comet to rhyme with Bailey, suggested that Haley call his band the Comets. (This event is cited in the Haley biographies Sound and Glory by John Haley and John von Hoelle, and Bill Haley by John Swenson and in Still Rockin' Around The Clock, a memoir by Comets bass player, Marshall Lytle.)

The new name was adopted in the fall of 1952. Members of the group at that time were Haley, Grande, Williamson and Lytle. Grande usually played piano on record, but switched to accordion for live shows as it was more portable than a piano and easier to deal with during musical numbers that involved a lot of dancing around. Soon after renaming the band, Haley hired his first drummer, Charlie Higler, though Higler was soon replaced by Dick Boccelli (a.k.a. Dick Richards). During this time (and indeed, as late as the fall of 1955), Haley did not have a permanent lead guitar player, choosing to use session musicians on record and either playing lead guitar himself or having Williamson play steel solos.

Comets Explode for Four Goals in the Third Period to Sweep a Three-In-Three Weekend

Posted on by

February 8, 2015 - American Hockey League (AHL) Utica Comets As the blizzard came rolling into Utica so did the Comets in their return to The Utica Memorial Auditorium as they defeated the Binghamton Senators 7-4 in a wild game that seemed to have everything on Sunday afternoon. After the victory, the Comets finished the weekend with a perfect 3-0 record and have now won four in a row.

Bobby Sanguinetti (2-0-2) and Will Acton (2-0-2) both recorded two goals each, along with three other Comets players that also found the net atleast once. Assists weren't exactly a rare commodity in Sunday's game, as Cal O'Reilly (0-2-2), Mike Zalewski (0-2-2), Dustin Jeffrey (0-2-2) and Alexandre Grenier (1-2-3) all found a pair of assists each.

The opening minutes weren't very enjoyable for the Comets as they let in two quick ones before they even hit the three-minute mark. At 1:18 Shane Prince walked into the slot and popped one off past Markstrom for the early 1-0 lead. A little over a minute later, Ryan Dzingel was awarded a penalty shot after being tripped up on a breakaway. Dzingel slipped one past Eriksson's glove side to make it 2-0.

It wasn't until the end of the first period, but the Comets finally put one on the board twenty seconds after David Dziurzynski took a cross checking penalty. Grenier was trying to pass one to the front of the net but his pass quickly turned into a goal after it deflected off of the body of a Senators defensemen, which got the Comets within one. Cal O'Reilly and Dustin Jeffrey both tallied assists.

Will Acton kept it going for the Comets in the second period after making his way around the back of Peter Mannino's net. Once Acton reached the far post, a backhander was all he needed to bury it past the sprawling Mannino for the equalizer and the short-handed goal.

Binghamton answered back five minutes later on the power play after Eriksson was called for a tripping penalty. Some minor confusion in front of the net and a shot in the slot from Derek Grant caused the puck to sneak past Eriksson, which took back the one-goal lead.

Trading goals seemed to be the trend for a while because at 17:58 Sanguinetti let one rip from the right dot and buried it glove side on Mannino to equalize it once again. O'Reilly and Grenier both received assists on the Comets third goal.

At the start of the third period, the goals started pouring in, more than they already had.

Utica took the lead for the first time in the game after a screened Mannino allowed Pedan to pound a blueline slapshot into the net to make it 4-3 at 4:08.

Ryan Dzingel tied it up again at 7:28 off of a quick pass from Buddy Robinson, but the Comets took back the lead and kept it roughly four minutes later off of a beautiful feed from Archibald which gave Sanguinetti the chance to bury his second of the game to make it 5-4.

Comets Move To 18-0 After Defeating The Wichita B-52's At Hartman Arena

Posted on by

February 8, 2015 - Major Arena Soccer League (MASL) Missouri Comets WICHITA, Ks (February 8, 2015) - The Missouri Comets (18-0) added one more victory to their perfect season after defeating the Wichita B-52's (8-10) 11-4 at Hartman Arena. Head coaches Vlatko Andonovski (Comets) and Kim Roentved (Wichita) played throughout the first half.

With 16 saves, Danny Waltman was named Borden Man of the Match. In addition, the Gig Harbor, Washington native recorded 26 saves on Friday against St. Louis.

League leader Leo Gibson added five more points to his name. Scoring one goal and recording four assists, the forward totals 73 points (36 goals and 37 assists).

The Major Arena Soccer League Central Division Champions were without Stefan Stokic (abdominal strain). In addition, Milan Ivanovic did not suit up, while Stephen Paterson and Cody Hoffman did not travel.

Led by Andonovski on the field, the Comets held the Wichita B-52's scoreless in the first half. Missouri finished the first quarter with a 5-0 lead after Brian Harris, Kiel Williams, team captain Vahid Assadpour assisted by Vlatko Andonovski, Bryan Perez and Josh Gardner each found the back of the net.

However, the Comets defeated goalkeeper Boris Pardo only once in the second stanza when Alain Matingou notched his only tally of the evening assisted by Perez to end the half 6-0.

Wichita was able to score in the third quarter courtesy of Alex Moseley and Kevin Jackson but Gibson, Assadpour and Perez all scored to end the third stanza with a temporary 9-2 score.

The last and fourth quarter saw the Comets score twice in a row when Harris and Andre Braithwaite each beat Pardo on goal. Late in the quarter, the home team added two more goals to the scoreboard, both scored by team leader Matt Clare ending the match with a final score of 11-4.

Next up, the Comets will look to close the regular season undefeated when they host the Tulsa Revolution and the Tacoma Stars at the Independence Events Center.

L-CSC Emerges as the Most Energy-Efficient Supercomputer in the World

New Orleans, LA, USA; November 20, 2014 -- A new supercomputer, L-CSC from the GSI Helmholtz Center, emerged as the most energy-efficient (or greenest) supercomputer in the world, according to the 16th edition of the twice-yearly Green500 list. The L-CSC cluster was the first and only supercomputer on the list to surpass 5 gigaflops/watt (billions of operations per second per watt). Like so many of the most energy-efficient supercomputers in the world over the past few years, L-CSC is a heterogeneous supercomputer that is powered by GPU accelerators, namely AMD FirePro S9150 GPUs. It marks the first time that a supercomputer using AMD GPUs has held the top spot.

In fact, the top three slots of the Green500 were powered by three different accelerators with number one, L-CSC, being powered by AMD FirePro S9150 GPUs; number two, Suiren, powered by PEZY-SC many-core accelerators; and number three, TSUBAME-KFC, powered by NVIDIA K20x GPUs. Beyond these top three, the next 20 supercomputers were also accelerator-based.

L-CSC achieved the first position on the November 2014 Green500 List with an impressive 5.27 gigaflops per watt. This system used Intel Ivy Bridge CPUs, AMD FirePro GPUs, and an energy-efficient software design to achieve this feat. TSUBAME-KFC, which was number one over the previous two editions of the Green500, came in third in this edition of the Green500. TSUBAME-KFC was the first supercomputer to have broken the 4 gigaflops/watt barrier. Finally, Suiren, a supercomputer from the High Energy Accelerator Research Organization/KEK in Japan, occupied the second spot between L-CSC and TSUBAME-KFC at 4.95 gigaflops per watt. Like L-CSC and TSUBAME-KFC, Suiren used Intel Ivy Bridge CPUs, but coupled them with many-core accelerators from PEZY-SC. These many-core accelerators consist of 1,024 independent processor cores.

Super confident students will hit it out of the PARCC

Posted on by

An audience of district parents at Haskell Elementary School on Feb. 4 listened as technology teacher Ryan Evans showed them how students taking the PARCC test this spring will be able to move through computer screens to record their answers.

Wanaque Superintendent Donna Cardiello is confident that her administration and staff have adequately prepared the district for the statewide roll out of the PARCC test (Partnership for Assessment of Readiness for College and Careers) this spring.

"We are absolutely ready," Cardiello told an audience of approximately 100 parents attending an informational meeting in the Haskell School gym on Wednesday night, Feb. 4. She recognized, however, that many parents have questions and concerns about the new computer-based assessments, which have replaced the annual NJ ASK (Assessment of Skills and Knowledge) for math and language arts for grades three through 11.

"It's the unknown of a new test," she said. "As adults, that may be frightening to us, but your children will find working on the computer engaging and motivating to them to pay closer attention. It's what they do."

With the help of two short videos and a visual presentation, Cardiello and several of her prominent staff members explained how the Common Core State Standards (CCSS), adopted by New Jersey in 2010, created the need for the PARCC test.

Lynda D'Angiolillo, director of curriculum and instruction, said that the CCSS has provided teachers and schools with a baseline for the skills that should be taught and mastered at specific grade levels.

A key shift in language arts standards has students reading complex texts earlier and thinking critically about what they've read.

"They're now required to compare material and cite text evidence in writing," D'Angiolillo said.

In math, the CCSS places greater focus on fewer topics, linking mastery of specific functions with certain grades. It's no longer enough to be able to add, subtract, or multiply; students should also display a "deeper understanding of the concepts," D'Angiolillo said.

Spreading spirituality with Hanuman Chalisa

Posted on by

Sri Datta Kshetram is keen to promote spirituality among the kids and others with chanting of Hanuman Chalisa and Karya Siddhi Hanuman Mantram with the suggestion of Datta Peetham head Ganapati Sachchidananda Swamiji. The Peetham recently conducted chanting of Hanuman Chalisa with 1.30 lakh people at Tenali and created a Guinness Book record.

Inspiration

With the inspiration from the success of the event, chanting of Hanuman Chalisa will be taken up in all 16 Datta Peethams, 7 Navanatha Kshetrams and associated temples.

Srikakulam Datta Kshethram Trust Board members Perla Balaji, Pannala Ramakrishna, K. Umadevi and others said that 1.30 crore chantings will be completed very soon.

They said the interested devotees can come to the temple on every Sunday morning and evening. According to them, the devotees who are unable to come to the temple at the stipulated time can complete chanting in their homes and provide details about the number of prayers. The numbers and other details will be sent to the Datta Peetham, Mysore, and incorporated in the final list for creating new record.

People lost peace of mind with the adoption of western culture. Our aim is to make people happy. Lord Hanuman strengthens will power and ensure happiness, said Mr. Rama Krishna.

Hows this for a unique workspace? This is where ISS astronauts get things done.

NASAs description:

This image of the interior view from the International Space Stations Cupola module was taken on Jan. 4, 2015. The large bay windows allows the Expedition 42 crew to see outside. The Cupola houses one of the space stations two robotic work stations used by astronauts to manipulate the large robotic arm seen through the right window. The robotic arm, or Canadarm2, was used throughout the construction of the station and is still used to grapple visiting cargo vehicles and assist astronauts during spacewalks. The Cupola is attached to the nadir side of the space station and also gives a full panoramic view of the Earth.

Large windows, lots of buttons and joysticks, and, of course, that awesome view. We cant all aspire to have a workspace like this, but its fun to look anyway.

Move over astronaut ice cream, Russian space food tubes have arrived.

As of Friday February 6, the All-Russian Exhibition Center in Moscow now sells authentic cosmonaut food to the public, the state-run Sputnik news service reported.

The centre, a sprawling trade show also known by the Russian acronym VDNKh, is marketing the cosmic cuisine in toothpaste-like tubes.

"Visitors [to VDNKh] will have a chance to try a full-course cosmonaut menu, including four kinds of soups, various meat dishes and a variety of desserts," the Sputnik report said.

"According to organisers, there will be 11 variations of tubes, each tasting like a different kind of food."

The selection, according to the Russian website Menu.ru, include marinated lamb and pork with vegetables, cottage cheese dessert with sea buckthorn fruit, and apricot, apple and blackcurrant puree.

The tubes, which are offered through a vending machine, cost 300 rubles, or about (US)$4.50, each.

They are produced by the same factory and using the same methods as the food that is prepared for the Russian cosmonauts onboard the International Space Station.

"Producers do not use any genetically-modified products and assure that the food in the tubes is made from natural ingredients only," the news service noted.

NOAA space weather satellite to provide solar storm warning

Posted on by

The Deep Space Climate Observatory, or DSCOVR, satellite will serve as an early warning beacon for impending solar storms while providing dramatic views of the Earth from its perch nearly 1 million miles toward the sun. NASA

Last Updated Feb 9, 2015 8:37 AM EST

Launch of a satellite dreamed up 17 years ago by Al Gore to provide continuous views of Earth via the internet and now repurposed to serve as a space weather station will have to wait at least until Tuesday to get into space, after problems with an Air Force radar derailed a launch attempt Sunday.

Perched atop a SpaceX Falcon 9 rocket, the Deep Space Climate Observatory, or DSCOVR, spacecraft had been scheduled for liftoff from the Cape Canaveral Air Force Station at 6:10 p.m. EST Sunday. But just two minutes and 27 seconds before liftoff, the countdown was aborted when engineers were unable to fix the radar problem in time.

SpaceX also had problems with a video transmitter on the first stage of the Falcon 9, but that gear was not required for launch. In any case, the scrub was a disappointment for the launch team and, presumably, to Gore, who was on hand for the flight.

SpaceX has now rescheduled the launch for 6:05 p.m. Tuesday, assuming the technical issues can be resolved in time and the weather cooperates. Weather was not favorable to try for a launch on Monday.

The 1,256-pound solar-powered DSCOVR satellite is bound for a point 930,000 miles toward the sun where the gravity of Earth and its star are in a sort of balance, allowing spacecraft to remain on station with minimal use of maneuvering fuel. Because of the deep space trajectory, the mission does not have the luxury of a launch window and must take off on time.

The primary goal of the repurposed $340 million DSCOVR mission is to replace an aging NASA satellite, providing space weather data to the National Oceanic and Atmospheric Administration.

"DSCOVR will provide the observations necessary to help us deliver warnings and alerts to industries affected by space weather so they can take action to protect infrastructure and be more resilient in the face of severe events," said Tom Berger, director of NOAA's Space Weather Prediction Center in Boulder, Colorado.

Assuming a problem-free launch, it will take DSCOVR about three-and-a-half months to reach L1. NASA then will spent about 40 days testing and checking out the satellite's instruments and subsystems before turning the spacecraft over to NOAA this summer for routine operations.
