D-Star is a closed system

What is the point of amateur radio? To learn about radio, propagation, the electromagnetic spectrum in general. To understand how it works, and maybe even build or modify your own equipment. The license, after all, is the only legal way to use the electromagnetic spectrum at interesting power levels.

In order to learn we must be able to inspect; To tinker, or at the very least have access to a specification we can build from.

Some amateur radio operators seem to complain that people don’t build their own radios anymore. That they just buy a box and antenna and are now consumers. This is not what I’m talking about here. First, you know in principle how your radio works. And you could build one that could replace it. Would it be as good as a modern fancy rig? Of course not. It wouldn’t be as good, but you could build one, and you could use it just as well as the bought one.

And if you learn enough, and tweak enough with the rig and antenna system, you could build something better for your particular environment.

When I first learned that D-Star used a proprietary voice codec I couldn’t understand Continue reading

Cisco boosts SD-WAN with multicloud-to-branch access system

Cisco is looking to give traditional or legacy wide-area network users another reason to move to the software-defined WAN world.The company has rolled out an integrated hardware/software package called SD-WAN Cloud onRamp for CoLocation that lets customers tie distributed multicloud applications back to a local branch office or local private data center. The idea is that a cloud-to-branch link would be shorter, faster and possibly more secure that tying cloud-based applications directly all the way to the data center.  More about SD-WANTo read this article in full, please click here

Throwing the baby out with the bathwater (No, you’re not Google, but why does this matter?)

It was quite difficult to prepare a tub full of bath water at many points in recent history (and it probably still is in some many parts of the world). First, there was the water itself—if you do not have plumbing, then the water must be manually transported, one bucket at a time, from a stream, well, or pump, to the tub. The result, of course, would be someone who was sweaty enough to need the forthcoming bath. Then there is the warming of the water. Shy of building a fire under the tub itself, how can you heat enough water quickly enough to make the eventual bathing experience? According to legend, this resulted in the entire household using the same tub of water to bathe. The last to bathe was always the smallest, the baby. By then, the water would be murky with dirt, which means the child could not be seen in the tub. When the tub was thrown out, then, no-one could tell if the baby was still in there.

But it doesn’t take a dirty tub of water to throw the baby out with the bath. All it really takes is an unwillingness to learn from Continue reading

Talking Internet of Things in Canada at IoT613 This Week

This week, 8-9 May, we’ll be at IoT613 in Ottawa, Canada, talking about our work on “Trust by Design” – the idea that privacy and security should be built into Internet-connected products, and not just an afterthought. We have been working with manufacturers to embrace the Online Trust Alliance’s IoT Trust Framework, which identifies the core requirements manufacturers, service providers, distributors/purchasers and policymakers need to understand, assess and embrace for effective IoT security and privacy. We also work to encourage consumers to demand security and privacy and to help policymakers create a policy environment that strengthens trust and enables innovation.

This week in Ottawa, we’ll have an Internet Society booth at the event both days, and on 9 May, Mark Buell, North American Bureau Director, will be part of an “IoT in Canada” panel that will “explore current IoT trends in Canada, identify the benefits of IoT for businesses and citizens and find out how Canada’s IoT ecosystem stacks up compared to the rest of the world.” Mark will speak about the Canadian Multistakeholder Process: Enhancing IoT Security, an Internet Society-led initiative to develop a broad-reaching policy to govern the security of the IoT for Continue reading

Network Break 233: The Dell EMC Product Deluge; Cisco Rolls Out Wi-Fi 6 APs

Today on Network Break we dive in the deluge of products announced at Dell EMC World, discuss new Wi-Fi 6 gear from Cisco, explore Cumulus's latest version of its NetQ switch management software, and tackle even more tech news. It's a bonanza episode so pack a few extra virtual donuts.

The Week in Internet News: Unencrypted USB Drives Pose Security Risk

No encryption for U(SB): About 55 percent of U.K. businesses don’t encrypt information on USB drives, according to the result of a survey published at Information Age. Also, 62 percent of executives surveyed admit to seeing USB devices in unsecured locations such as desks, drawers, and exposed office spaces.

Out of touch: As healthcare providers explore ways to use Artificial Intelligence to treat patients, the human touch may end up a casualty, NPR says. AI could “create a gulf between health caregivers and people of more modest means,” with some people not getting the human interaction with healthcare professionals that they need, the story says.

Ship it with blockchain: FedEx CIO Rob Carter, speaking at a recent conference, called on the international shipping industry to mandate the use of blockchain to track shipments, Computerworld notes. The technology could help weed out counterfeit goods, backers say.

Intelligent standards: The U.S. White House has launched an effort to develop AI standards, and it’s asking for public input, NextGov writes. An executive order on AI directs the U.S. National Institute of Standards and Technology to issue a set of standards and tools that will guide the government in its adoption of Continue reading

Dell EMC launches GPU-loaded machine learning server

The latest news from Dell Technologies World is a high-end machine learning server for the data center that has four, eight, or even 10 Nvidia Tesla V100 GPUs for processing power.The Dell EMC DSS 8440 is a two-socket server with two of the new Xeon Scalable processors and is specifically designed for machine learning applications and other demanding workloads. Each Tesla is capable of more than 100 teraflops, so the 10 GPU machine is one petaflop of processing power. Dell claims the DSS 8440 is almost on par with performance by the DGX-1, which is also Tesla-powered.[ Read also: What is quantum computing (and why enterprises should care) ] Obviously this is not a machine for beginners. That would be Dell EMC’s 740 and 7425 servers, which support up to three GPUs, and the 4140, which supports up to four GPU cards.To read this article in full, please click here
