Revolutionary data compression technique could slash compute costs

There’s a major problem with today’s money-saving memory compression used for storing more data in less space. The issue is that computers store and run memory in predetermined blocks, yet many modern programs function and play out in variable chunks.The way it’s currently done is actually, highly inefficient. That’s because the compressed programs, which use objects rather than evenly configured slabs of data, don’t match the space used to store and run them, explain scientists working on a revolutionary new compression system called Zippads.The answer, they say—and something that if it works would drastically reduce those inefficiencies, speed things up, and importantly, reduce compute costs—is to compress the varied objects and not the cache lines, as is the case now. Cache lines are fixed-size blocks of memory that are transferred to memory cache.To read this article in full, please click here

Automation Solution: Find Source of STP Topology Changes

Topology changes are a bane of large STP-based networks, and when they become a serious challenge you could probably use a tool that could track down what’s causing them.

I’m sure there’s a network management tool out there that can do just that (please write a comment if you know one); Eder Gernot decided to write his own while working on a hands-on assignment in the Building Network Automation Solutions online course. Like most course attendees he published the code on GitHub and might appreciate pull requests ;)

Wonder what else course attendees created in the past? Here’s a small sample.

Health care is still stitching together IoT systems

Government regulations, safety and technical integration are all serious issues facing the use of IoT in medicine, but professionals in the field say that medical IoT is movingforward despite the obstacles. A vendor, a doctor, and an IT pro all spoke to Network World about the work involved.To read this article in full, please click here(Insider Story)

Cisco issues critical security warning for Nexus data-center switches

Cisco issued some 40 security advisories today but only one of them was deemed “critical” – a vulnerability in the Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode data-center switch that could let an attacker secretly access system resources.The exposure, which was given a Common Vulnerability Scoring System importance of 9.8 out of 10, is described as a problem with secure shell (SSH) key-management for the Cisco Nexus 9000 that lets a remote attacker to connect to the affected system with the privileges of a root user, Cisco said.To read this article in full, please click here

BrandPost: Higher Ed IT, Your Digital Transformation Has Arrived

It’s here, and it’s sweeping campuses nationwide: Digital Transformation (Dx) in higher education. While other industries have already made giant leaps in Dx (just look at the retail industry with tech titan Amazon and the transportation industry with innovator Uber), Digital Transformation in higher ed is now starting to take shape.The topic of Dx in higher ed is being addressed at widely attended events like the Educause Annual Conference, where higher education institutions of all sizes come together to discuss the topic of technology. Still in the relatively early stages of Dx, higher ed IT professionals are wondering if their IT departments are set up to support the evolving digital ecosystems at their institutions – and working to ensure that they are.To read this article in full, please click here

BrandPost: What Internal IT Support Can Learn from External Customer Support

Over the last couple of years, there’s been a lot of attention on how customer support is changing and how brands are using customer support as a business differentiator. But where’s all the attention on how businesses are using internal-facing support as a key competitive advantage?(Crickets chirping. Still chirping.)The truth is, customers are a prime focus for businesses but internal employees a distant second, at best. It seems to make sense to prioritize external-facing customer support over internal-facing IT support. But here’s the deal: your employees are consumers, too – they’re out there in the world interacting with A+ service and support teams, and it’s changing their expectations back at the office. They expect internal IT support to deliver the same level of service that they experience as customers.To read this article in full, please click here

How the Internet Society’s Privacy Statement Stacks Up

For ten years, the Internet Society’s Online Trust Alliance (OTA) has published an annual comprehensive survey of 1,200 sites’ security and privacy practices. The 10th edition of this Audit has been released and can be found here. As part of the Audit, we score each site’s privacy statement against 29 criteria, ranging from whether it is linked to on the site’s homepage, to whether it states how the site handles children’s data.

For this blog post, we decided to use the Internet Society’s current privacy statement as an example, to illustrate the criteria used, and to show how a privacy statement fits into the bigger picture of an organization’s privacy practices. A privacy statement is only one piece of an organization’s overall privacy practices – although, as the public-facing piece, it is of course important. Other aspects (which are not included in the OTA survey) include:

  • expressing and committing to a set of overall privacy principles
  • having internal policies and practices that put the public-facing privacy statement into practice
  • internal and external enforcement of the commitments expressed in the privacy statement

There are myriad ways to structure a privacy statement and, to be frank, many privacy statements are written with different goals Continue reading

Dell enters the on-premises, pay-as-you-go business with VMware’s help

Dell EMC kicked off its Dell Technologies World show by announcing an alliance with VMware to offer Dell EMC hardware on-premises without having to buy it outright.The VMware Cloud on Dell EMC program offers the entire VMware software-defined data center (SDDC) stack on hyperconverged VxRail hardware. Rather than purchasing it outright, customers can pay for the service every month based on use. [ Read also: How to plan a software-defined data-center network ] Sound familiar? HP Enterprise has a similar program called GreenLake that does the same thing. Also, Dell has a program called Cloud Flex, a consumption financing offering for on-premises hardware.To read this article in full, please click here
