IDG Contributor Network: 6 key questions to answer when setting up an IoT center of excellence

Adopting IoT technology is a significant, company-wide undertaking. It requires a large dedication of resources and budget across multiple departments. Rightfully, the C-level has expectations for their investments. But before you can get to the payoff, there is an inordinate amount of decisions to be made and changes to endure. Not the least of which will be to learn new technology, establish new processes and define new job descriptions.But, because the result is so valuable to an organization’s bottom line – for example, greater yields of manufactured goods, extended life of decade’s old equipment, and more – tech leaders often compare the adoption of IoT technology to the early days of computers in business.   To read this article in full, please click here

Memcached servers can be hijacked for massive DDoS attacks

A flaw in the implementation of the UDP protocol for Memcached servers can allow anyone to launch a massive Distributed Denial of Service (DDoS) attack with little effort.The problem was first discovered by security researchers at content delivery network (CDN) specialist Cloudflare. Since then, CDN specialist Akamai and security provider Arbor Networks have also published their findings.Also read: Getting the most out of your next-generation firewall Memcached is a Web-based massive memory cache for database-drive sites, such as websites, that caches the most frequently retrieved data and keeps it in memory rather than getting it from the hard disk over and over again. It is a combination of open-source software and standard server hardware that consists of memory, memory, and more memory.To read this article in full, please click here

BrandPost: Swisscom and Huawei Sign MoU on NetCity Project

At MWC 2018, Swisscom and Huawei announced they has signed a Memorandum of Understanding (MoU)  on NetCity project, intended to build a world-class, highly reliable, next-generation wireline network infrastructure that can provide customers in Switzerland with innovative products and services.NetCity, a project developed by Huawei and leading carriers for building the cities of the future, is intended to bring humanity a step closer to achieving a fully-connected, intelligent world by means of constructing a broadband, cloud-based and intelligent network architecture.The MoU marks an important step toward building a leading position for the two companies in technology, business and social responsibility. Working hand in hand on this project, Swisscom and Huawei will explore new concepts in wireline network deployment, developing innovative solutions that enable "zero-touch operations" for telecom and data center networks and accelerating the application of cloud computing, telemetry, AI, and Big Data on networks.To read this article in full, please click here

Information Gatekeeping: Not a Laughing Matter

There’s a joke that goes something like this: How do you make a little money in the online news business?

The punchline: Start with a huge pile of money, and work your way down from there.

It seems the same joke would work for the online comedy business, judging by the layoff news coming out of Funny or Die in January. Recently, Splitsider.com published an interesting Q&A with comedy veteran Matt Klinman, and he talked about the woes of online comedy outlets.

Klinman focused his ire on Facebook and its role as an information gatekeeper, in which the site determines what comedy clips to show each of its users. But much of his criticism could have just as easily been targeted at a handful of other online gatekeepers that point Internet users to a huge percentage of the original content that’s out there.

As Klinman says about Facebook, these services have created their own “centrally designed Internet” in which they serve as “our editor and our boss. They hide behind algorithms that they change constantly.”

As a thrice-laid-off online journalist, I can sympathize. I’m pretty sure I can’t blame any of the current gatekeepers for my 2002 layoff Continue reading

IDG Contributor Network: The future of IoT device management

The Internet of Things (IoT) continues to expand its reach into homes, businesses, social settings, and other environments, as more and more devices are connected with the purpose of gathering and sharing data.Clearly, there are several potential benefits of IoT from a consumer standpoint. Apart from the convenience aspect, smart connected products can lead to increased energy efficiency, improved safety and security, higher product quality, etc.But unfortunately, the current consumer IoT device landscape is still immature. For consumer IoT devices to thrive, device management capabilities need to evolve in a few ways.IoT device management is the process of authenticating, provisioning, configuring, monitoring and maintaining the device firmware and software that provides its functional capabilities. Effective device management is critical to establishing and maintaining the health, connectivity, and security of IoT devices. IoT application vendors typically provide comprehensive device management with their solutions. But all bets are off if that application vendor goes out of business and you would like to use your devices with a similar application from a different vendor. Consumers are increasingly faced with unexpected device obsolescence and landfills are starting to fill up with expensive IoT bricks. What consumer IoT needs is a truly Continue reading

Sorting list in Python

During my Python studies, I came across something that didn’t make much sense to me so I had to learn and investigate (with the help of experts). What you can usually do in Python is to modify a variable and assign the result to the same variable. Because a piece of code is usually worth much more than an explanation: [crayon-5a96e02e428e1312116645/] When you want to sort a list, that behavior is a bit different: let’s pretend I have a list of ARP entries into my switch: [crayon-5a96e02e428ee971099170/] If I want to sort it and reassign the value of it to the previously used variable I would use this code (Let’s pretend arp_entries is my variable that contains all these entries): [crayon-5a96e02e428f6056918892/] [Read More...]
