Our leaders have time and time again emphasized a core aspect of the EMC Federation strategy and functioning model: “(we) offer best-of-breed, integrated, technology while preserving customers’ ability to choose…” In this blog, I reflect upon how this strategy applies to allowing customers the ability to choose Open Source Cloud OS – OpenStack.OpenStack is making rapid strides in both private and public cloud markets. The earlier skepticism on hype is waning as we see the momentum translate to tangible deployments. Let’s go over some numbers if you need convincing. A recent OpenStack user survey showed 512 total deployments; 209 of these being production deployments. This momentum seems even more impactful within the EMC customer base. A recent EMC pre-sales/field survey has revealed that 50% of customers are running OpenStack today; 53% of those are in production. So it is not surprising that EMC’s strategy of ‘providing of our customers with choice’ resulted in OpenStack being a viable option across our federated family. Let me explain this in more detail.Pivotal Customers Can Choose OpenStackPivotal offers a comprehensive set of application and data services that run on top of PaaS (platform-as-a-service) called Cloud Foundry®. Cloud Foundry is an open source platform that can run on any cloud infrastructure like VMware, OpenStack, or Amazon Web Services. Even though the Pivotal distribution of Cloud Foundry runs on VMware vSphere, there are many prominent members of the Cloud Foundry community who offer Cloud Foundry PaaS on OpenStack. Piston Cloud, which had originally contributed Cloud Foundry interface for OpenStack, now offers PaaS on Piston Cloud, which is based on OpenStack. IBM, with BlueMix PaaS cloud, and HP, with Cloud Application PaaS, have recently announced Cloud Foundry running on OpenStack infrastructure. Not only is it being offered by many prominent vendors, you can also choose to run Pivotal applications and big data services on any of these multi-cloud platforms. Watch out for the inevitable open source progression: OpenStack to Cloud Foundry!VMware Customers Can Choose OpenStackMany are perplexed by the complex relationship between VMware and OpenStack. I think the relationship is largely complementary; OpenStack is an open and flexible framework to pull all the cloud IaaS components together, whereas VMware provides the best-of-breed cloud components. As we see a rising number of OpenStack production deployments, there is also a broad demand for the integration of the two for Enterprise class solutions and use cases. It is for this reason that VMware is heavily investing in the integration, giving its customers the choice of having an open framework with best-of-breed cloud components. VMware is now the fifth largest contributor of OpenStack code in the current IceHouse release.Many immediately get network virtualization as an integration point, as VMware NSX is one of the founders of OpenStack networking, but the integration points are far more pervasive than just networking. You can now trigger complex vCenter functions like vMotion off the OpenStack compute module, Nova. vSphere storage policies and advanced vSAN capabilities can be facilitated through the OpenStack storage module, Cinder. vCOPs integration allows monitoring and troubleshooting through OpenStack. There are many more, and you can be rest assured that the roadmap will continue to get richer with time.EMC Customers Can Choose OpenStackEMC’s strategy for OpenStack is twofold:OpenStack projects allow vendors to add capabilities through “plugin” architecture. Every storage business unit at EMC is committed to providing direct plugins for OpenStack. We currently offer plugins for VNX, VMAX, and ViPR; plugins from Isilon, ScaleIO, and XtremIO are already available to customers for beta evaluation. OpenStack’s roots were with object storage over commodity hardware. However, as deployments mature, we now see it running a broad mix of production workloads. Plugins give customers the choice of a variety of EMC storage with appropriate service levels to run their workloads.ViPR is EMC’s software-defined storage platform and hence complements OpenStack by providing rich automation features, as well as integrated management of objects, blocks, and later files. In other words, you will get integrated access to EMC (what you get from direct plugins) and non-EMC storage, and on top of that you should be able to get enhanced automation features like provisioning, masking/zoning, FAST and VPLEX volumes, as well as rich data services. You can check-out my blog on ‘ViPR in the stack’ for more details.Returning to my original point, EMC customers can choose any cloud. I hope to have shown you that OpenStack represents as a viable choice across each of the EMC federation’s horizontal stacks.
The announcement comes after the pension fund tendered for several transition managers.It said it was doing this as it reviewed “various aspects of the investment arrangements” within the fund.Lancashire also recently announced an investment fund merger with the London Pension Fund Authority (LPFA).The funds said they were investigating the possibility of creating a merged £10bn investment fund, as well as combining governance and administration arrangements.In other news, bulk annuity provider Pension Insurance Corporation (PIC) has transferred more than £2bn of liabilities to reinsurers Hannover Re and Reinsurance Group of America (RGA).The reinsurance contracts were conducted over the course of 2014 and shifted risk from PIC to its counterparties.Over 2014, PIC signed several deals, including a £1.6bn buy-in with the Total UK Pension Plan.The company said its £2bn figure was the largest amount of reinsured risk conducted over the course of a calendar year and brings the insurer’s total to more than £7bn.Total’s £1.6bn of liabilities has been fully reinsured with Hannover Re, according to the company.Head of longevity risk Khurram Khan said the company would continue to use large and sometimes complex reinsurance deals to manage the differing aspects of the risk taken on.Liabilities transferred to insurers via bulk annuities are expected to exceed £11bn in 2014, as scheme funding levels improve and market forces encourage competitive pricing.PIC dominated the £7.8bn of liabilities written in 2013, accounting for more than 50% of the market.However, 2014 was dominated by Legal & General, which wrote more than £8.3bn in bulk annuities, including a £2.5bn buyout with TRW. The Lancashire County Pension Fund (LCPF) has tendered a consultancy framework agreement as it looks to review various aspects of its investment arrangements.The £5.3bn (€6.7bn) pension fund said it might make changes to its overall investment strategy, and that the framework agreement would cover eight different “lots” of services, including asset classes for public and private equity, real estate, infrastructure and credit.It will conduct a mini-competition between potential consultancies depending on where framework providers are selected for the different services.The framework agreement will last for four years, and the maximum number of participants has been set at 80.
(The 138 km highway replaces a 50-year old ice road. Photo: Charlotte Morritt-Jacobs/APTN)Charlotte Morritt-Jacobs APTN News SaturdayWhile the fanfare will fade and the visitors will go back south, for the generations of eager Northerners the wait is finally over – the Inuvik Tuktoyaktuk Highway is open.It was a historical day for the residents of two communities in the Northwest Territories Wednesday when the 138 km all-weather Inuvik to Tuktoyaktuk opened to the public.This ends the 50-year history of Canada’s longest winter ice road, a road that linked Tuk to the Dempster Hwy. – and to the rest of the country. For the Gwich’in, Inuvialuit, and Metis it’s an extension of the lifeline that was the ice road to Tuk.“This road is freedom. People that don’t have the equipment the harvesting that they use to do, or they aren’t as physically active as they use to be. This gives them access to do things that they love to do,” said Jimmy Kalinek, a tourism and guided tours operator from Inuvik.The ice road was only open a quarter of the year but it was a permanent fixture in the hearts of many.The ice road was laid with memories, both frightening and happy.“January, in the dark of 1991, I was changing a tire and I heard a noise. I looked around and there was a wolf behind me. I got up and made a noise and shown a flashlight at it and there was seven more surrounding me,” said Joe Cooke, an ice road maintenance operator with the government of the NWT for over 30 years.For Kalinek, his memory was being able to see family.“It was always Christmastime; you go to Aklavik and to Tuk and see family members there and go and celebrate with the community. You would go see the drummers or go to the jamborees, there’s a lot of good memories,” said Kalinek.Commuters of the ice road held celebrations in April 2017 to make the end of the last ice road season for the small hamlet of 900.APTN spoke with residents of their bewilderment at the thought of future generations never being able to experience the road.Nostalgia for the lifeline that was the ice road to Tuk mixed with the hope for new possibilities from year-round connectivity.But the permanent road comes at a cost – $300 million.The project was two thirds federally-funded and one-third territorial.On the day of the opening, Northwest Territories Premier Bob McLeod was joined by Canada’s Governor General Julie Payette, representatives from local Indigenous groups and other government dignitaries.McLeod dubbed the opening of the road as “an important day for the Northwest Territories and Canada.”A ribbon ceremony was held in Inuvik before government officials, media and the public took to the highway for the inaugural drive to the arctic coastal community, but it was in Tuk, at the evening ceremony, that the gravity of the new infrastructure set in with Northerners.“Tuk’s my home. It will always be my home,” said Nahan Kuptan, a Saliqmuit drummer and dancer. “I’m happy our community name is out there, I’m proud.”The idea of a permanent road has been first floated in the 1960s, but construction occurred four years ago. This so-called “road to resources” was built to give industry greater access to Arctic oil and gas.The vision for the road would shift in 2016 when Prime Minister Justice Trudeau and former U.S. President Barack Obama placed an Arctic moratorium on oil and gas.This squashed the hopes for any developments in the near future and left some to question the highway’s $300 million price tag.The cost of the road was not on the minds of the residents of Tuk at the ceremony who see two-lane, all-weather gravel highway as more than just a connection between two isolated communities.In a town, where food costs are high and a flight to the neighbouring community costs a few hundred dollars, community members are hoping that the road will lower the cost of living.The government has also projected a $2.2 million annual increase due to tourism for Tuk.The spirit of the town was present throughout Wednesday as a feast was served with traditional food, drummers and dancers took to the stage and crafts were sold as keepsakes of the special occasion.
Chelsea’s boss Maurizio Sarri is insisting that is awed by Tottenham’s display as they kept Blues midfielder Jorginho in check and defeated Chelsea 3-1 on Saturday.Sarri believes Tottenham tactics was instrumental to the midfield battle won by Spurs and when describing his team’s performance in the opening 20 minutes as, the Chelsea boss said:“It was clear after five minutes of the match that it was very difficult to use Jorginho as usual,” the Chelsea boss told a news conference after his first Premier League defeat, via FourFourTwo.“We had to get the ball from the centre-backs to the opposite full-backs, that was the only way to have one or two seconds of playing the ball.”“We were surprised because they normally play with a 4-2-3-1 or 4-3-3, but they played 4-3-1-2.”“After five minutes, the situation was very clear. We lost a lot of balls and, against Tottenham, it’s very dangerous to lose the ball in your half.”“In short counter-attacks, they are one of the strongest teams in Europe. It was a disaster and, after 20 minutes, 2-0 was the minimum.”Maurizio Sarri satisfied despite Juventus’ draw at Fiorentina Andrew Smyth – September 14, 2019 Maurizio Sarri was satisfied with Juventus’ performance on Saturday afternoon after finishing a tough game at Fiorentina 0-0.Sarri says work in training is key now: ‘We have to try to do something because the defensive phase was a disaster today. The offensive players pressed badly, the midfield defended not very well, and the defensive line was a disaster.’#TOTCHE— Chelsea FC (@ChelseaFC) November 24, 2018On the other hand, Spurs manager Mauricio Pochettino maintains that going by Sarri’s analysis, Chelsea are the ones that consistently alters its shape in each match.“The plan was to win the game and we won,” said Pochettino.“We don’t use a fixed formation. If you follow us in all the games we play in the Champions League, cup and Premier League, we don’t talk about the formation, we talk about tactics or animation.”“We talk about how we play in a different way with possession in the opposite half, how we organise the team in a defensive situation when we don’t have the ball.”
Journal information: Proceedings of the National Academy of Sciences (Phys.org) —Fifteenth and sixteenth century Chinese workers transported enormous stones to the Forbidden City by carrying them in sledges along roads of artificial ice, according to Jiang Li of the University of Science and Technology in Beijing and his colleagues. The researchers translated a document showing that in 1557, workers used this method to transport a 123-ton stone more than 70 kilometers. Li and his team say that dragging large stones over ice, rather than over dry ground, reduced the amount of friction created and the number of workers needed for the job. The study appears in the Proceedings of the National Academy of Sciences. Construction of China’s Forbidden City, in present-day Beijing, began in 1417. The home of China’s emperors for almost 500 years, The Forbidden City incorporates stones weighing more than 100 tons extracted from the Dashiwo quarry, 70 kilometers away. The heaviest of these is the Large Stone Carving, which weighs more than 300 tons.Previous researchers assumed that the Chinese used wheeled vehicles to move the stones. The Chinese were using wheeled vehicles for transport by around 1500 BC, and there are no images of workers dragging stones over dry ground. However, none of the wheeled vehicles built before 1596 could carry more than 95 tons. Although some books mention that workers used an artificial ice path to transport the Large Stone Carving, there are no detailed historical records of this event.Li and his colleagues translated a Chinese text written in 1618 that describes how workers brought a 123-ton stone to the Forbidden City in 1557, during a mid-winter renovation project. The workers placed the stone on a sledge, which they then dragged along an artificial ice path, created by pouring well water onto the ground and then allowing the water to freeze. They dug wells every half kilometer. By pouring water over ice that had already frozen, they created a liquid surface that decreased the friction between the sledge and the ice. The workers had time to move the sledge across the liquid film before it froze.The team calculated that it would have taken 1,537 men to drag the load over dry ground. Dragging a sledge over ice would have required 338 men. Lubricating the ice would have reduced the workforce to 46 men. An ice road also eliminated the need to lay out wooden planks to create a smooth surface.Architects of the reconstruction debated whether to use sledges or mule-driven wagons. They chose sledges because they were safer and more reliable than wagons, although sledges required more time, money and manpower.The research suggests that, at the time, Chinese engineers knew more about friction than Western engineers did. Workers likely slid massive stones, such as this 300-ton marble carving in front of the Hall of Supreme Harmony in the Forbidden City, Beijing, China, along artificial ice paths.

Although in China spoked wheels appeared ca. 1500 B.C., in the 15th and 16th centuries sliding sledges were still used in transporting huge stones to the Forbidden City in Beijing. We show that an ice lubrication technique of water-lubricated wood-on-ice sliding was used instead of the common ancient approaches, such as wood-on-wood sliding or the use of log rollers. The technique took full advantage of the natural properties of ice, such as sufficient hardness, flatness, and low friction with a water film. This ice-assisted movement is more efficient for such heavy-load and low-speed transportation necessary for the stones of the Forbidden City. The transportation of the huge stones provides an early example of ice lubrication and complements current studies of the high-speed regime relevant to competitive ice sports.

Unraveling biological networks (Phys.org)—A trio of math and computer scientists has developed a means for developing generalized frameworks that allow for clustering networks based on higher-order connectivity patterns. In their paper published in the journal Science, Austin Benson and Jure Leskovec with Stanford University and David Gleich with Purdue University outline their framework ideas and offer real life examples of ways their techniques can be applied to help understand complex networks in simpler ways. Nataša Pržulj and Noël Malod-Dognin with University College London offer an analysis of the work done by the trio in a Perspectives piece in the same journal issue. Journal information: Science Social network diagram. Credit: Daniel Tenerife/Wikipedia More information: A. R. Benson et al. Higher-order organization of complex networks, Science (2016). DOI: 10.1126/science.aad9029AbstractNetworks are a fundamental tool for understanding and modeling complex systems in physics, biology, neuroscience, engineering, and social science. Many networks are known to exhibit rich, lower-order connectivity patterns that can be captured at the level of individual nodes and edges. However, higher-order organization of complex networks—at the level of small network subgraphs—remains largely unknown. Here, we develop a generalized framework for clustering networks on the basis of higher-order connectivity patterns. This framework provides mathematical guarantees on the optimality of obtained clusters and scales to networks with billions of edges. The framework reveals higher-order organization in a number of networks, including information propagation units in neuronal networks and hub structure in transportation networks. Results show that networks exhibit rich higher-order organizational structures that are exposed by clustering based on higher-order connectivity patterns. As the authors note, it is not difficult to make out patterns in very small networks, a person trying to do so need only watch the system at work for a period of time. It is when networks become bigger and more complex that they become unwieldy. Even in such cases, however, low-order patterns are often still easy to discern—counting nodes or edges for example, offers some degree of network size, though doing so tells you very little about what the network does and how—that is where high-order organizational principles come into play. Unfortunately attempts to create a means for providing more information or detail about such systems has to date, not met with much success. In this new effort, the researchers describe a framework they have developed that offers some of the pattern recognition seen in smaller networks, with more complex networks.They start, Pržulj and Malod-Dognin note, with one of the more common higher-order structures known as small network subgraphs, which they refer to as network motifs—those that are statistically significant can be used as building blocks for the building of a mathematical framework, which is of course what the researchers have done. Relationship identification among the motifs was done by applying clustering algorithms. The result is a framework that highlights and/or identifies which of the motifs are the most critical when a network is in operation.The trio tested their framework technique by using it to analyze part of the neuronal network of a roundworm, and report that it revealed the particular cluster of 20 neurons responsible for performing actions such as standing and wiggling its head. They also gained insights into air traffic patterns by using it to perform an analysis of airports in the U.S. and Canada. They suggest such frameworks may be used in a wide variety of applications.
