Is a 4G hot spot still needed in today’s world?

Maybe my experiences are different from those who travel more often, but I’ve been finding that the need for a Wi-Fi personal hot spot that connects to a 3G or 4G wireless network has diminished as more locations are providing their own Wi-Fi with a backhaul to a faster connection. Hotels, coffee shops, even airports seem to offer faster networking options than those provided by some of these devices. Granted, a lot of these places come with a price tag for the access, with some at outrageous prices. If you aren’t being reimbursed by your company for that access, finding less expensive Internet access can be tricky. Even the “free” ones cost in terms of having to watch an ad, or they limit your speed to basic functions such as downloading email or basic web surfing (don’t even think about streaming Netflix or uploading video).To read this article in full or to leave a comment, please click here

Inventor of new lithium-ion battery responds to skepticism

The inventor of a new lithium-ion (Li-on) technology that is purported to be safer, faster-charging, and longer-lasting than today's rechargeable batteries responded to experts wary of his claim, saying new discoveries invite strong skepticism.John Goodenough, 94, a professor in the Cockrell School of Engineering at the University of Texas at Austin and co-inventor of the original lithium-ion battery, this week said he demonstrated new battery cells that have at least three times as much energy density as today's Li-on batteries.

L.A. and NYC still rank behind smaller cities in wireless performance

The two biggest cities in the U.S. -- New York City and Los Angeles -- continue to rank well below many smaller U.S. cities in overall wireless performance, according to millions of field tests performed by RootMetrics in the second half of 2016.The New York metro area, with 18 million people, ranked just 66th in the latest round of tests of the nation's largest 125 metro areas. Meanwhile, L.A., with 12.1 million people, ranked 49th. In testing done by RootMetrics in the first half of last year, New York finished 59th, L.A., 99th.[ Further reading: The votes are in: Which mobile data provider is best? ] L.A. improved in two of six measurements: call and data performance. New York's drop was largely driven by a "steep decline" in network speed and data performance, RootMetrics said.To read this article in full or to leave a comment, please click here

Review: SaltStack shifts devops into high gear

The only sane and efficient way to manage a large numbers of servers—or even a few dozen, if they change often—is through automation. Automation tools have to be learned and mastered, so they exact a significant up-front cost, but they dramatically reduce the administrative burden in the long run. Perhaps most important, they provide a staunch line of defense against the fatal fat-fingered mistake, which even the most sophisticated cloud operators struggle to avoid.Ease of use. Configuration management is simple with SaltStack. Because Salt uses the YAML configuration format, states are can be written quickly and easily. YAML state descriptions are structured well, with solid readability. The support for Mako, JSON, Wempy, and Jinja allows developers to extend Salt’s capabilities. The availability of built-in modules makes it easy to configure and manage states.To read this article in full or to leave a comment, please click here(Insider Story)

Critical infrastructure: Off the web, out of danger?

The debate over the chances of a catastrophic cyber attack taking down a major part of the nation’s critical infrastructure (CI) has been ongoing for a generation.But it hasn’t been settled – in some ways it is more intense now than ever.On one side are those, including high government officials, who warn of a “cyber Pearl Harbor” that could leave swaths of the country in darkness and cold – without electric power – for months.Retired Adm. James Stavridis, dean at Tufts Fletcher School and a former NATO supreme allied commander, used that term just three months ago, saying such an attack would be aimed either at the electrical grid or the financial sector.To read this article in full or to leave a comment, please click here

Web-Scale IT in the Enterprise

The first and only NOS to support LinkedIn’s Open19 project

Today we are excited to announce our support of Open19, a project spearheaded by LinkedIn. Open19 simplifies and standardizes the 19-inch rack form factor and increases interoperability between different vendors’ technology. Built on the principles of openness, Open19 allows many more suppliers to produce servers that will interoperate and will be interchangeable in any rack environment.

We are thrilled to be the first and only network operating system supporting Open19 for two reasons. First, this joint solution offers complete choice throughout the entire stack — increasing interoperability and efficiency. We believe the ease of use of this new technology helps expand the footprint of web-scale networking and makes it even more accessible and relevant.

The second reason is that we are continually dedicated to innovation within the open community, and this is one more way we can support that mission. We believe that disaggregation is not only the future but the present (read more about why we think disaggregation is here to stay). When a company like LinkedIn jumped into the disaggregate ring, we knew we wanted to be a part of it.

What is Open19?

The primary component, Brick Cage, is a passive mechanical cage that fits Continue reading

The theft of unstructured data is extremely common. It can be very difficult to safeguard emails and files when a lot of people have access. Even the CIA is not immune, judging by the recent exposure of its hacking tools via WikiLeaks. It’s ironic that the CIA’s hacking guides have been hacked, but it just goes to show how difficult it can be to prevent.Carelessly handled unstructured data is an easy target, and it can prove very valuable for hackers. Since unstructured data may not be monitored, attacks and successful exfiltrations often go unnoticed for long periods.To read this article in full or to leave a comment, please click here
