Generating numeric sequences with the Linux seq command

One of the easiest ways to generate a list of numbers in Linux is to use the seq (sequence) command. In its simplest form, seq will take a single number and then list all the numbers from 1 to that number. For example:$ seq 5 1 2 3 4 5 Unless directed otherwise, seq always starts with 1. You can start a sequence with a different number by inserting it before the final number.$ seq 3 5 3 4 5 Specifying an increment You can also specify an increment. Say you want to list multiples of 3. Specify your starting point (first 3 in this example), increment (second 3) and end point (18).To read this article in full, please click here

Wi-Fi 6 is slowly gathering steam

The next big wave of Wi-Fi technology, 802.11ax, is going to become more commonplace in enterprise installations over the course of the coming year, just as the marketing teams for the makers of Wi-Fi equivalent will have you believe. Yet the rosiest predictions of revolutionary change in what enterprise Wi-Fi is capable of are still a bit farther off than 2020, according to industry experts.To read this article in full, please click here(Insider Story)

Wi-Fi 6 will slowly gather steam in 2020

The next big wave of Wi-Fi technology, 802.11ax, is going to become more commonplace in enterprise installations over the course of the coming year, just as the marketing teams for the makers of Wi-Fi equivalent will have you believe. Yet the rosiest predictions of revolutionary change in what enterprise Wi-Fi is capable of are still a bit farther off than 2020, according to industry experts.The crux of the matter is that, while access points with 802.11ax’s Wi-Fi 6 branding will steadily move into enterprise deployments in, the broader Wi-Fi ecosystem will not be dominated by the new standard for several years, according to Farpoint Group principal Craig Mathias.To read this article in full, please click here

A new spin on interconnects for colocation data centers

It has been almost a year since I first wrote about Stateless, Inc., a startup devoted to bringing software-defined interconnects (SD-IX) to colocation data centers. At that time, the company was just announcing its plans to reinvent the means to connect workloads across data centers, hyperscale clouds and on-premises footprints using SD-IX. The intent was to give colo service providers a simpler way to quickly deploy network services for their tenants. Those plans have come to fruition and the company has announced the general availability (GA) of its Luxon SD-IX platform.To read this article in full, please click here

Benefits of modern campus networking

Call it “trickle-down networking” if you like. But what has long been possible—and even best practice— in data center networking is now moving aggressively into and onto campus networking ecosystems. And with that move companies and organizations can realize numerous benefits in or on the campus networks they own or operate. As readers peruse this list of potential benisons, they’ll undoubtedly hit hot buttons with their users (thanks to increased features and functionality) and with management (thanks to cost savings and improved efficiencies that reduce staff time commitments and involvement).

Delivering key capabilities

With the adoption of data center tools and technologies in campus networks, a handful of key capabilities becomes available throughout. These include Power over Ethernet (PoE), which makes it possible to extend services more easily and affordably, and to integrate Internet of Things (IoT) capabilities more directly (such as sensors, surveillance cameras, ID badge readers and so forth). In addition, networks gain ready access to 802.1X capabilities when they adopt a data center model, including improved and more powerful authentication mechanisms, as well as access and security control.

Moving to data center-oriented networks usually also brings voice VLANs into the networking picture. This not only offers Continue reading

The Week in Internet News: New Chinese Law Regulates Encryption

Crypto-regulation: A new law in China regulates the use of encryption, but it’s aimed at strengthening it, at least in some settings, Reuters reports. The law is aimed at aiding the development of a digital currency in China, and it is focused on “facilitating the development of the cryptography business and ensuring the security of cyberspace and information,” according to the official Xinhua news agency said. The law also that all state secrets be stored and transmitted using “core and common” encryption, Engadget says.

The Year Ahead

Welcome to another year of The Morning Paper! Over the holidays I spent
some time mapping out a partial conference calendar for the year, and thinking about the kinds of papers I want to be reading. In a typical year, I’ll cover somewhere north of 120 papers on this blog. That’s a tiny drop in the ocean compared to the amount of research published. And then as well as dipping my toes into the new, I also want to make more space for papers that have stood the test of time. Following the Lindy effect these are the ones most likely to continue giving ten years or more into the future. Where have we come from? Where are we now? And where are we heading? My only firm rule for paper selection is that I must find it interesting. As regular readers of The Morning Paper will know though, my interests are pretty broad and will no doubt take many twists and turns over the course of the year.

Through the course of a year I often have the pleasure of bumping into many readers of The Morning Paper. And very often they tell me apologetically that they don’t always Continue reading
