first_imgBecause of the lack of a definitive air link to an international gravity base station, the Antarctic Peninsula gravity network was originally, and still is, tied to the Potsdam gravity system via long ship links to South America (Renner 1981, Kennett 1965). An indirect link from the British Antarctic Survey (BAS) scientific station at Rothera to an International Gravity Standardisation Net 1971 (IGSN 71) base station in the UK had previously been made via a link to the BAS gravity station on the Falkland Islands in Port Stanley (McGibbon 1988). Whilst the apparent gravity difference between Port Stanley and the base station in the UK had been calculated via a two-way air tie using a LaCoste and Romberg meter (McGibbon 1988) and later strengthened with three two-way air ties using four LaCoste and Romberg meters (Bassett 1987), the link between Port Stanley and Rothera was based on a one-way tie that included a lengthy ship borne passage (McGibbon 1988). The weakness of this link insured that the adopted gravity value at Rothera continued to be based on the ship ties made by Griffiths et al. (1964) and Kennett (1965). This note describes the strengthening of the gravity link between Rothera and Port Stanley and the subsequent reassignment of the adopted gravity value at Rothera Station.last_img read more


first_imgPure Nonsense – Separating Fact from Fiction in FlashThe buzz about NVMe has recently reached a fever pitch, and rightfully so. It’s the perfect technology buzz word – a nice little acronym that blends the right amount of nerdy and cool and promises to change the landscape of storage forever. Who wouldn’t want to talk about that? But as we’ve discussed before, it is important to understand that NVMe is more than simply putting a fancy new interface on the same old flash drives.As one of the pioneers of NVMe, Dell EMC couldn’t be happier that the world is building with anticipation that NVMe is finally coming to fruition in mainstream enterprise storage.   When I say pioneer, I mean that literally – Dell EMC co-developed the NVMe standard starting back in 2007 and by the end of the year, we’ll release our next NVMe array, which will be the first of many in our mainstream all flash portfolio.You may have heard Pure Storage talking about their new “100% NVMe” array, but before you get sucked in, let’s level set on a few things:NVMe is an interface, which replaces SAS/SATA to overcome the limitations of these protocols that were designed over 30 years ago for spinning hard disk drives, and thereby take advantage of the parallelism of modern CPUs and SSDs.NVMe is NOT media, which in the short term is NAND-based flash, and is the same media that vendors have been shipping in all-flash arrays for years.NVMe will enable a modest improvement in latency but at a premium price.NVMe will, in the future, open up high-speed, low-latency access to the next generation storage media called Storage Class Memory, or SCM, (for example, 3D XPoint). And that’s where things get interesting. SCM will dramatically improve latency over NAND-based flash media, just as NAND-based flash dramatically improved latency over spinning disk media.In other words, SCM is Emerald City and NVMe is the yellow brick road – the game-changer in storage will be the combination of NVMe and SCM – not NVMe alone.So what about that snazzy new “100% NVMe” array from Pure Storage?  They built their own proprietary “NVMe drives” (dubbed “Flash Modules”) for this new array, which was expensive, and customers are going to have to pay for that.  To date, there have been no performance benchmarks published for the new FlashArray //X (also of note – existing performance metrics for Pure Storage’s FlashArray//M have been removed from their website as well).  Which makes you wonder…What benefits does the FlashArray //X have beyond unspecified performance over their last generation array?What performance will you really get from it, and does it justify the premium?Given their proprietary approach, what is the go-forward path to SCM and when will that come?The proprietary road is littered with failure.  See Violin Memory as a recent example.Dell EMC’s Strategy for NVMe in StorageWe recently evolved our NVMe strategy based on customer feedback and are now focused on continuing to deliver NVMe across our portfolio over the next 6 to 24 months.  In fact, we’ll launch our first “mainstream” NVMe array by the end of the year.  Unlike Pure Storage, we are leveraging industry-standard technology and collaborating with industry leaders like Intel to ensure our offerings are ready for enterprise requirements, while also minimizing price premiums for early adopters.  In addition, this approach allows us to accelerate and optimize delivery of the ideal enterprise-ready Storage Class Memory (SCM) devices as soon as they become available.Dell EMC also continues to lead the industry in driving standards in NVMe with our cutting-edge portfolio of PowerEdge servers.  We will offer NVMe in a variety of consumption models for storage including arrays, software-defined storage, converged and hyper-converged infrastructure solutions.  As always, they will be backed by Dell EMC’s world-class engineering, services and support organizations – who have been designing and testing solutions for mission critical environments for decades.last_img read more


first_imgIt is time to break the misconception that CIOs and CFOs have competing priorities to spend and save money. Every executive is tasked with doing the right thing for the whole company, not just for his or her function. That said, IT has traditionally been accounted for as a General and Administrative cost, so rather than being perceived a strategic partner, IT is deemed a big cost center and a lever to pull to reduce costs.In today’s hypercompetitive global marketplace, creating and introducing a new product faster and closing a deal and collecting cash faster is not just an advantage, it’s a necessity. IT holds the keys to make this happen, but we can’t do that alone. We need to work closer with our CFO and business partners to reduce, reallocate and reinvest in modernizing and transforming IT for the future.Recognizing that the relationship between the CIO and CFO is also transforming, Dell EMC and Forbes Insights recently published a study titled, IT TRANSFORMATION: Success Hinges on CIO/CFO Collaboration. After reading the study, Dell’s CFO Tom Sweet and I discussed the findings in this video, but I also wanted to share my perspective as Dell and VMware’s CIO.First, while nearly all respondents agreed that CIO and CFO collaboration is critical, 89 percent said there are significant barriers including outdated reporting structures, incentives and attitudes. Well, the good news is that both CIOs and CFOs are under immense pressure to do what’s best for the company and to maintain or gain a competitive edge. If we don’t, we will trail our competition or worse be disrupted by an upstart hungry to eat our lunch. How’s that for a unifying incentive? On the plus side, collaborating more effectively with the CFO enables us to better understand the company’s goals and financial pressures to strategically advise and give our business partners the levers needed to make informed decisions that propel us forward. So, it is a win-win.Second, according to the study, it is becoming even more important for CIOs to have managerial and business skills, with 74 percent of respondents adding that CIOs should have an entrepreneurial mindset. For more than 20 years, I have made it my mission to aggressively and creatively deliver the innovation, performance and scale the business has demanded despite having flat or shrinking budgets. However, our continual focus on keeping the lights on and hitting tighter financial targets distracts us from being entrepreneurial. Not only do we need to find ways to automate and run leaner so we can better focus on innovating IT, but we need to show the CFO our progress doing so. This builds trust and enhances our ability to sell our strategy and justify investments with the CFO and other leaders to truly modernize and transform IT.And finally, the study shines a light on our need to drive a cultural change between CIOs and CFOs by designating change agents on both sides of the aisle and incentivizing them to collaborate. However, this alignment doesn’t stop at the CFO level. Rather than reacting to requests, IT professionals need to closely partner with all our business leaders to truly understand their digital transformation strategy and share the responsibility for ensuring the success of their business initiatives. By embracing the Dell Digital Way that leverages Pivotal technology and paired programing, an agile methodology, Pivotal Cloud Foundry and Spring-based tools, we are digitally transforming how our team does business. In addition to enabling us to rapidly deliver a much better end product for the business, this also builds confidence with the CFO and our business partners.The bottom line, we are at a crossroads. We can continue down the traditional, frequently traveled road and risk being disrupted. Or we can transform IT to work closer with our CFO and the business to not only address the financial pressures all companies face, but modernize IT to advance our digital transformation strategy and ultimately help Dell win big. Personally, I refuse to be disrupted, so the road less traveled looks much brighter to me.last_img read more


first_imgOn December 15, 2011 the VMBB issued $43.7 million in 2011 Series 5 Bonds to assist 26 municipalities to refinance outstanding debt issued through the US Department of Agriculture-Rural Development. The USDA-RD debt was originally issued to fund principally municipal drinking water and sewer projects. The refinancing bonds will save participating municipalities over $4,109,786 in future debt service payments.Through the December 15, 2011 issue of $25.9 million in 2011 Series 6 Refinancing Bonds, the Bond Bank was able to refinance its 2003 Series 2 bonds resulting in $1,750,000 in future debt service payment savings for 27 Vermont municipalities and school districts.

first_imgPresident Joko “Jokowi” Widodo has said he is prepared to take “extraordinary steps”, including a Cabinet reshuffle, if his ministers fail to take the COVID-19 crisis seriously, in a video uploaded to the Presidential Secretariat’s official YouTube channel on Sunday. In the video, apparently shot during a Cabinet meeting on June 18, the President lambasted the ministers for taking the situation too lightly. “The atmosphere in the last three months and in the next three months should be one of crisis,” he said. “We should not consider [this situation] to be normal. That is very dangerous. And I still see that many of us see this as normal.”He urged all ministries to cut through the red tape and accelerate their spending in order to stimulate the economy.“Once again, do not act as if everything is normal,” he said. “If you need to issue a ministerial regulation [to accelerate spending], issue it. If you need a presidential regulation, I will issue it.”Jokowi cited the state budget for the health sector as an example of the slow spending. “We have budgeted Rp 75 trillion [US$5.28 billion] but only 1.5 percent has been disbursed,” he said. “All the money that’s supposed to be for the people is stuck there.” Read also: ‘Crisis like no other’ will shrink Indonesia’s economy, IMF forecastsHe also called on the Health Ministry to immediately pay out the financial incentives promised to health workers on the frontlines of the COVID-19 outbreak.He closed the uncharacteristically fiery address by saying that he was prepared to take extraordinary political and governmental steps to address the current crisis. “I will take any steps necessary, including extraordinary ones, for our 267 million people,” he said. “[I might] disband agencies. [I might] reshuffle [the Cabinet]. I have considered many options.”The June 18 meeting was the first Cabinet meeting held face-to-face since the COVID-19 outbreak in the country began. The meeting was closed to the public and the press.According to the government’s official count, Indonesia has 54,010 confirmed COVID-19 cases with 2,754 deaths as of Sunday.
