EU wants to ease commercial drone use with future flight rules

The European Commission wants to make it easier for lightweight drones to fly autonomously in European airspace -- with logistics, inspection services and agricultural businesses set to benefit.Last Friday, the Commission unveiled a plan to improve the safety of drones flying at low altitude.It wants to introduce a consistent set of rules across the EU for flying drones in "U-space," its name for regulated airspace under 150 meters in altitude.Simpler regulations will be welcomed by multinational businesses such as gas giant Engie, which is developing drones for tasks such as pipeline or building inspection or for cleaning the insulators on high-voltage overhead power lines.To read this article in full or to leave a comment, please click here

AMD launches its Epyc server chip to take on Intel in the data center

It's not just the folks at AMD who hope that that the company's Epyc server processor, officially launched Tuesday, will break Intel's stranglehold on the data-center chip market.Enterprise users, web hosting companies and hyperscale cloud providers all want competition and choice in server chips to curb costs and fuel innovation."OEMs have been looking for an alternative to Intel for a long time, and with Intel having 98 percent market share I can say that there's absolutely a need, from the OEM point of view and the channel point of view," said Patrick Moorhead, principal at Moor Insights & Strategy.Judging from specs, performance benchmarks and memory features as well as the supporting voices from software and hardware makers in the data center ecosystem, Epyc has the best shot of any chip to hit the market in years at putting a crack in Intel's dominance.To read this article in full or to leave a comment, please click here

Worth Reading: Open IPv6 Resolvers

Open DNS resolvers that answer queries coming from anyone have been the main component of a large number of DDoS attacks in recent years. By sending queries with a spoofed source address to such open resolvers, the resolver will send the answers to that spoofed address. An attacker spoofs the address of his/her target and sends a large number of queries to an open resolver, creating a deluge of large DNS answers towards the target. —APNIC

IETF: The Harmful Consequences of Postel’s Maxim

This Internet-Draft resonates strongly with me: Jon Postel’s famous statement in RFC 1122 of “Be liberal in what you accept, and conservative in what you send” – is a principle that has long guided the design of Internet protocols and implementations of those protocols. The posture this statement advocates might promote interoperability in the short […]

Cisco brings intent-based networking to the end-to-end network

Today at a media and analyst event in San Francisco, Cisco announced it plans to deliver on “intent based” networking, which has the potential to be the biggest change ever in the way networks are managed.Intent-based systems operate in a manner where the administrators tell the network what it wants done and the how is determined by the network and then the specific tasks are automated to make this happen. For example, if a business wants to secure all traffic from accounting, that command is issued and the systems would take care of all the technical details.   Network changes are automated and continuous, so if a worker moves, all the policies and network settings follow him or her.To read this article in full or to leave a comment, please click here

Cisco brings intent-based networking to the end-to-end network

Becoming a digital business is of paramount importance to IT and business leaders today. Becoming digital means being able to move with speed and adapt to market trends faster than the competition. This might sound simple – just work faster, but in practicality becoming a fast-moving organization is very difficult as legacy IT processes can limit an organization's ability to operate quickly. Many parts of IT have evolved to increase business agility such as application development, which has embraced DevOps. However, the network has largely stood still.There has been some great innovation in the area of software defined networking (SDN) that has made network operations more efficient but this hasn’t fundamentally changed the way networks operate. Today most organizations are managing their networks using traditional processes that are largely reactive in nature and manually intensive. As we move into a world where literally everything will be connected, network operations will get crushed under the weight of having to perform more tasks faster to keep up with the needs of the business.To read this article in full or to leave a comment, please click here

On the ‘web: A new way to deal with DDoS

Most large scale providers manage Distributed Denial of Service (DDoS) attacks by spreading the attack over as many servers as possible, and simply “eating” the traffic. This traffic spreading routine is normally accomplished using Border Gateway Protocol (BGP) communities and selective advertisement of reachable destinations, combined with the use of anycast to regionalize and manage load sharing on inbound network paths. But what about the smaller operator, who may only have two or three entry points, and does not have a large number of servers, or a large aggregate edge bandwidth, to react to DDoS attacks?

I write for ECI about once a month; this month I explain DOTS over there. What to know what DOTS is? Then you need to click on the link above and read the story. ?

How to keep Linux from hanging up on you

When you run a command in the background on a Linux system and then log out, the process you were running will stop abruptly. If you elect to run the command with a no-hangup command, on the other hand, it will continue running and will store its output in a file.Here's how this works. The nohup command instructs your process to ignore the SIGHUP signal that would normally shut it down. That allows you to leave time-consuming processes to complete on their own without you having to remain logged in. By default, the output of the command you are running will be left in a file named nohup.out so that you can find your data the next time you log in.To read this article in full or to leave a comment, please click here

How Red Bull Racing uses IoT to win

“Fast” seems like a simple concept, on the surface. Go fast enough and you can win races, even highly competitive ones like Formula 1 auto racing. But it takes a complex, sophisticated IT setup to get to the necessary level of fast, according to the CIO of Red Bull Racing, Matt Cadieux.In particular, the extensive IoT deployment that the team uses to squeeze the maximum  performance out of its cars is key to success, Cadieux saidThe carNaturally enough, it all starts with the car. F1 cars are essentially very light-weight, low-flying aircraft, mating an engine capable of around 600 horsepower with a fiberglass body and spindly chassis weighing in at about 1,500 pounds. They can get from zero to 100mph in an incendiary four seconds, corner like waterbugs, and keep drivers relatively safe even from collisions at the blistering speeds that F1 races can reach.To read this article in full or to leave a comment, please click here

198 million American voter records found unprotected on the internet

You’d think if someone had amassed personal information on nearly every registered US voter, and stored that information on an Amazon S3 storage bucket, that it would at least be protected with a password. But thanks to a misconfigured server, personal data of 198 million Americans voters could be downloaded by anyone who happened across it. It is believed to be the largest leak of voter records to have ever occurred anywhere in the world.That giant oops caused by Deep Root Analytics, a data analytics firm contracted to compile the information for the Republican National Committee, contained names, birthdates, home and mailing addresses, phone numbers, party affiliations, suspected ethnicities and religions, as well as analytics on who people would likely vote for and their stance on hot-button issues such as gun control and abortion.To read this article in full or to leave a comment, please click here

Worth Reading: Connecting Sleep and Income

A third of American workers report they regularly get fewer than seven hours of sleep a night, leading to the loss of some 1.2 million working days and robbing the U.S. economy of an estimated $226 billion annually, according to a 2016 study by Rand Europe. And 65% of Americans are losing sleep because of money, according to a recent CreditCards.com report. That’s the big picture. —Market Watch
