Empowering Our Private Cloud Through API Exposure

first_imgThe RESTful model is easy for developers to use in terms of methodology with specific methods (GET, POST, PUT, and DELETE).REST is based on HTTP, which is designed to scale and is tolerant of network latency—very important in the cloud.If you call an API multiple times with the same data, the calls return the same result, which facilitates retry and error-handling scenarios.We’re adamant about API exposure at every layer of our private cloud for one reason: automation supports a highly agile environment and is essential to the success of our hybrid cloud strategy. Please check out the paper and tell us what you are doing in this space. I would love to read about everyone’s ideas.- CathyCatherine Spence is an Enterprise Architect and PaaS Lead for the Intel IT Cloud program.Connect with Cathy on LinkedInRead more posts by Cathy on the ITPN Why Is This so Important?First, as Amazon foresaw, you cannot scale fast enough unless you automate and to do so you need APIs. Intel IT, acting as its own cloud provider, requires automation and self-service. If all you have is a GUI with no scripting capabilities, you cannot automate. For example, you cannot scale out and add more applications, and—just as importantly—scale back as business needs change. Therefore, we strive to provide an API and a command-line interface for every layer in our private cloud—including IaaS, PaaS, and DBaaS.Automation, enabled by APIs, also helps IT keep our costs down and do more with less—the IT mantra of the century. Current industry data suggests that in a highly automated environment, a single system admin can manage 1,000 servers or more. While we haven’t reached that point yet, we have made significant strides in increasing automation and providing more services without increasing cost. More importantly, automation is critical for business agility supported by self-service capabilities. As the speed of business increases, users need tools and automation to “do it themselves” as opposed to waiting for specialized personnel to act on their behalf.Finally, exposing APIs is a critical part of our move to a hybrid cloud model, where workloads can be balanced among clouds by using policies. Without consistent API exposure, such a hybrid cloud model would be impossible.How Have We Implemented API Exposure at Intel?We strongly encourage our application developers to create cloud-aware applications—even the cloud itself should incorporate cloud-aware principles. Part of being cloud-aware is implementing small, stateless components designed to scale out and using web services to interact among components. We are heavily promoting the use of RESTful APIs for web services, for several reasons: Back in the early 2000s, Amazon may have been the progenitor of today’s API economy, when the company CEO issued a mandate that all teams must expose their data and functionality through service interfaces. While Intel IT’s executives have not issued such a directive, we make sure that every layer in our enterprise private cloud exposes and consumes web services through APIs. In fact, this a key component of our overall hybrid cloud strategy, as described in the enterprise private cloud white paper we recently published. As the IT Principal Engineer for Intel’s cloud efforts, I’ve taken APIs’ important role to heart and have integrated this concept into our architecture.last_img read more

Kohli blasts match referee over no ball gaffe

first_imgBengaluru: A livid Virat Kohli on Thursday stormed into the match referee’s room and hurled abuses at him following Royal Challengers Bangalore’s (RCB) home defeat against Mumbai Indians (MI) in the Indian Premier League (IPL), which was marred by a glaring umpiring blooper that cost RCB dear, reports said. According to a report, right after the presentation ceremony, a furious Kohli barged into match referee Manu Nayyar’s room and used abusive language to let his displeasure known. As per the report, Kohli even told the match referee that he didn’t care if he was penalised for violating the code of conduct. Also Read – Puducherry on top after 8-wkt win over ChandigarhNeeding 41 runs from 4 overs, RCB looked to be cruising against MI at the M. Chinnaswamy Stadium in Bengaluru before Jasprit Bumrah and Lasith Malinga tightened the screws on the home team and won the game for MI by 6 runs. But the game will be remembered for umpire S. Ravi’s failure to spot a no-ball off the final delivery of the match. With RCB needing six runs from the last ball to tie the game, Lasith Malinga bowled a dot ball, but replays showed it should have been a no-ball as he overstepped. Also Read – Vijender’s next fight on Nov 22, opponent to be announced laterRCB skipper Virat Kohli made his displeasure known at the end of the game, saying that the teams were not playing club cricket and the officials needed to be more careful. During the presentation ceremony, Kohli said: “We are playing at the IPL level and not playing club cricket. The umpires should have had their eyes open. That is a ridiculous call (last ball). If it is a game of margins, I don’t know what is happening. They should have been more sharp and careful out there.” MI skipper Rohit Sharma too backed Kohli and said that these mistakes shouldn’t happen as they were game changers. “I just got to know when we crossed the rope. Somebody told me it was a no ball. These kind of mistakes are not good for the game of cricket, it’s pretty simple. In the over before that, Bumrah bowled a ball which wasn’t a wide. Those are game changers. There’s a TV up there, they have to watch what’s happening. It is as simple as that. “Players can’t do much. The only thing they can do is walk off and shake hands because it was the last ball. It’s disappointing to see that. I hope they rectify their mistakes like we do when we make mistakes,” Sharma rued. A senior official of the Board of Control for Cricket in India said the howler in Thursday’s match was waiting to happen since there have been no proper assessment and judgement. “What you saw (yesterday) was a symptom and not the disease. It has been two years since the Umpires’ Committee functioned. The process that was followed earlier was that the umpires were assessed during the year by a panel of former umpires who were on the Umpires’ Committee. “The committee members were also free to visit and see the assessment being done. All of that went out of the window once the Committee of Administrators (CoA) moved in lock, stock and barrel. Mistakes happened then too, but there was a system because of which the umpires were apprehensive since they were being judged,” the official said.last_img read more

Local Legislators Talk Possible Second Special Session

first_imgRepresentative Sarah Vance: “There’s many of us in the House minority, the House Republicans, who believe we can accomplish the work now. The operating budget could have been completed before the 120 days expired, but because people were holding out for what they want they did not move it. There was not any new things done this week that could not have been done prior.” KSRM News spoke with each of our local legislators on Tuesday, and none of them seemed optimistic that the Legislature will be able to find agreement prior to the end of the first special session on Friday. Representative Gary Knopp: “A second special session to address the capital budget and the PFD is really what I think needs to happen. We’re just out of time. We can’t pass a capital budget now and expect the Senate to rubber stamp it and concur, and no time to conference it. That is my belief. Unless something strange happens, I think that’s what needs to happen. We are simply out of time.”  The Senate unanimously passed the Fiscal Year 2020 operating budget during a floor session on Monday.  The Alaska House of Representatives passed the same operating budget on Sunday which does not include a PFD. Representative Ben Carpenter: “It is a possibility if the House Majority fails to act in the next three days on a capital budget then we would have to go into a second special session in order to have a capital budget. We are at the mercy of people who are not thinking logically. I do not understand why we can’t do the job the state has asked us to do in a timely manner.” center_img Senator Peter Micciche: “We unfortunately clearly need another special session to settle the PFD issue. Although half of us, including me, in the Senate voted for a $3,000 PFD and tried to get it back into the budget yesterday we couldn’t get an 11th vote. At this time the House has not made any kind of a definitive statement on a dividend. A legislative session should be over in 90 days, 110 at the most, unfortunately the House was late to organize. We had to pass a budget and send it to the governor so that the process can continue on an operating budget, and so he has opportunity to veto what he believes is right.”  Facebook0TwitterEmailPrintFriendly分享Lawmakers won’t be packing their bags anytime soon amid a looming second special session, where they’re expected to reach a compromise on two major issues… the PFD and a capital budget.

Global brokerage firms turn bullish on Indian markets despite it being an

first_imgA bronze bull sculpture is seen as an employee walks out of the Bombay Stock Exchange (BSE) building in Mumbai  (representational image).Reuters fileGenerally an election year is considered as a year of caution for the investors and in fact, the recommendation by the brokerage firms is also on the safer side. Despite election-related uncertainty, global brokerage firms including HSBC, BNP Paribas and Morgan Stanley have turned bullish on Indian equities. Last year, India ended as the best-performing Asian market and the best-performing major global market after Brazil. The Sensex finished 6 per cent higher in 2018. Domestic stocks have fared better than most global equities.In comparison, the MSCI Emerging Market and MSCI World indices were down by 16 per cent, amid a crash in the US and China markets. The reason attributed to global volatility were economic uncertainty in the US and trade tensions with China. A sharp decline in oil prices and strong buying by domestic funds have helped Indian markets withstand global volatility in the latter part of 2018.Financial daily, Business Standard reported that HSBC, in its recent report, has upgraded its weightage on India from ‘neutral’ to ‘overweight’. It is betting on financial, metal and consumer discretionary sectors in the Indian context. Herald van der Linde, head of equity strategy for the Asia Pacific at HSBC, said, “Aside from the elections, the macro backdrop is looking better in 2019 than in 2018. Inflation is low, and our economists are now looking for a rate cut in April. We expect overall GDP (gross domestic product) growth to accelerate, possibly supported by reforms (such as GST) starting to bear fruit.” Reuters fileIn this year, Indian benchmarks have underperformed vis-a-vis major global indices with only a jump of around 1.8 per cent. In comparison, Nasdaq Composite, CAC 40, Hang Seng, S&P 500, DJIA, FTSE and the Karachi 100 have jumped higher in the range of 6 per cent to 12.1 per cent during the same duration. Additionally, analysts at BNP Paribas too have gone bullish on the Indian markets and have expected the S&P BSE Sensex to rally from the current levels and hit 40,000 levels. The brokerage firm has estimated a jump of around 8.3 per cent from the current levels but has also red-flagged against election-related volatility in the first half of the calendar year 2019.The election commission on Sunday, March 10, announced the schedule of the general election for 2019.

More Than 49M Expansion Begins At Holocaust Museum Houston

first_imgWikimedia CommonsHouston Holocaust MuseumThe Holocaust Museum Houston’s expansion project that will double its size has begun with the relocation of two of their most valuable historical artifacts, the rescue boat Hanne Frank and a World War II-era rail car of the type used by Nazis to transport their victims to concentration camps.The Houston Chronicle reports , in what was a slow and careful operation using a high-capacity crane, the two museum pieces were relocated from their place in the patio, where they were previously on display, to another area 120 feet away to protect them from the risk of being damaged during the construction project.TNT Crane & Rigging, the company hired by the museum to move the artifacts, took about two hours to finish the work.“There is so much safety and calculations involved,” said Cody Viteritto, a technician working with the TNT crew. He noted that while moving heavy objects of this size involve roughly the same kind of procedures, the historical artifacts required special attention. “Critical consideration, in this case, was the value of the items,” he said.Hanne Frank is one of the fishing boats that were used by Christians in Denmark who risked their lives during three weeks in 1943 while ferrying to Sweden more than 7,200 Jews — along with roughly 700 people from other population groups — and evading Nazi occupation troops who were intent on deporting them to Germany.According to the museum, although the name of the boat resembles that of Holocaust victim and writer Anne Frank, there isn’t a known relation with the author of The Diary of a Young Girl. The ship was initially called Jørn Finne but later re-registered in 1985 with the Royal Danish Register of Shipping.Twitter via @MYorke27The Houston Holocaust MuseumThe Houston museum is the only one in the U.S. that has a Danish rescue boat from World War II.The rail car, a historical piece weighing 10.5 metric tons, also represented a challenge during the move.“It took years for us to be able to acquire that rail car,” recalled Peter N. Berkowitz, a former member of the museum’s board that managed that acquisition.Berkowitz, currently the chairman of the Texas Holocaust and Genocide Commission, said that one of the characteristics of that rail car is that it has a design that was produced in small quantities during the Nazi era in Germany. It was also designated as a historical artifact by Alfred Gottwaldt, the worldwide authority in World War II’s German railroad history, who died in 2015.Transferring the artifacts “is very important because now they will literally be inside the museum for the first time,” said Kelly J. Zúñiga, the museum’s CEO. It will allow for better preservation of these historical artifacts, as construction has already started around the old building at 5401 Caroline St.The construction project, which officially began Monday with a projected cost of $49.4 million, will more than double the museum’s space to a total of 57,000 square feet. At its scheduled completion in spring 2019, it will become the fourth largest Holocaust museum in the country, according to the spokesperson Robin Cavanaugh.“We think this is going to be the most beautiful Holocaust museum in the United States,” Zúñiga said. “We have the unique aspect that we teach the stories of the Holocaust through the eyes of our Houston survivors. So it’s very personalized from the Houston perspective. It’s our story, and that makes us extremely unique.”Chaja Verveer, a Holocaust survivor who lives in Houston, was at the site observing the moving operation of the artifacts.It was one of those times when “those memories” came to her mind. She was 3 years old when she was transported, without any family member, from the Westerbork to the Bergen-Belsen Nazi camp in Germany in a rail car just like the museum’s.In reality, “the memory is more physical than anything else; you are too little to know what is going on or to articulate,” Verveer said. The memory is “like a lump in my stomach.” Sharelast_img read more

Study of parrotlets hopping offers clues on how dinosaurs might have developed

first_imgBut then the researchers made a bit of a leap themselves: They wondered if the wing-assisted hopping they observed might have been used by dinosaurs, which could have led to full flight. They built a model that replicated four particular dinosaurs and their behaviors, and found that for two of them, wing-like boosted flight could have increased their jump length by 20 percent. This edge, they suggest, could very well have led to increasingly long jumps as the dinosaurs grew smaller and lighter over time, eventually leading to fully realized flight. (Phys.org)—A pair of researchers from Stanford University has studied the energy used by a type of small parrot as it hops from branch to branch during foraging. As they note in their paper uploaded to the open access site Science Advances, Diana Chin and David Lentink found that the bird’s techniques optimized energy expenditure and may have been similar to techniques used by dinosaurs that led to flight. Explore further By directing their jumps at energy-efficient takeoff angles and making additional wingbeats, birds can fly effectively over longer distances to forage in trees. Credit: Diana Chin, Lentink Lab Parrotlets are, as their name implies, small parrots that live from Mexico to southern parts of South America—and four of them live in the lab operated by Chin and Lentink. Prior research has shown that parrotlets tend to hop from branch to branch while foraging, though sometimes, the distance is great enough that they must fly, as well. In this new effort, the researchers began by wondering if the hopping was random, or if it was optimized. To find out, they created force-sensitive perches and filmed their charges as they hopped from branch to branch.In studying the data and watching how the birds foraged, the researchers found that when distances between branches were small enough, the birds simply hopped. When the distance was greater, the birds used their wings to give them an added push, a sort of accented hop. By comparing the amount of energy expended, the researchers found that the strategy used by the birds did, indeed, optimize energy usage—using their wings as a partial assist during a hop required less energy than simply taking flight. The research pair concluded that the birds were very efficient in their hopping and jumping. Parrotlets can assist and extend their long jumps with small “proto-wingbeats,” which bird ancestors may have used to develop their foraging flight capabilities.

DOI: 10.1126/sciadv.1603041AbstractBirds frequently hop and fly between tree branches to forage. To determine the mechanical energy trade-offs of their bimodal locomotion, we rewarded four Pacific parrotlets with a seed for flying voluntarily between instrumented perches inside a new aerodynamic force platform. By integrating direct measurements of both leg and wing forces with kinematics in a bimodal long jump and flight model, we discovered that parrotlets direct their leg impulse to minimize the mechanical energy needed to forage over different distances and inclinations. The bimodal locomotion model further shows how even a small lift contribution from a single proto-wingbeat would have significantly lengthened the long jump of foraging arboreal dinosaurs. These avian bimodal locomotion strategies can also help robots traverse cluttered environments more effectively. By directing their jumps at energy-efficient takeoff angles and making additional wingbeats, birds can fly effectively over longer distances to forage in trees.
