There’s a buzz in the industry about a new type of product that promises to change the way we secure and network our organizations. It is called the Secure Access Service Edge (SASE). It was first mentioned by Gartner, Inc. in its hype cycle for networking. Since then Barracuda highlighted SASE in a recent PR update and Zscaler also discussed it in their earnings call. Most recently, Cato Networks announced that it was mentioned by Gartner as a “sample vendor” in the hype cycle.To read this article in full, please click here
If you’ve ever had to restart a time-consuming process because your SSH session was disconnected, you might be very happy to learn about an interesting tool that you can use to avoid this problem – the screen tool.Screen, which is a terminal multiplexor, allows you to run many terminal sessions within a single ssh session, detaching from them and reattaching them as needed. The process for doing this is surprising simple and involves only a handful of commands. [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ]
To start a screen session, you simply type screen within your ssh session. You then start your long-running process, type Ctrl+A Ctrl+D to detach from the session and screen -r to reattach when the time is right.To read this article in full, please click here
While 3D XPoint memory has been shipping as Optane from Intel for two years, it hasn't found a great deal of traction, but a new server DIMM and an upcoming Micron product release may change that.
IBM continued its Red Hat and open-source integration work this week by adding Red Hat OpenShift support to its blockchain platform and bringing a Kubernetes Operator for Apache CouchDB along side its hybrid-cloud services offering. The ability to deploy IBM Blockchain on Red Hat OpenShift, the company’s flagship enterprise Kubernetes platform, means IBM Blockchain developers will have the ability to deploy secure software, either on-premises, in public clouds or in hybrid cloud architectures.To read this article in full, please click here
A few years ago, a blind man rode in a car in Austin, Texas. Normally, such a trip would not make national headlines. However, this blind man was alone in the car. That might sound like the set up for a joke, but it’s actually a pointer toward the future. The car was one of Google’s self-driving cars. After the ride, the gentleman exited the vehicle and entered history.That’s just one story in a never-ending stream of prognostication, commentary and “gee whiz” quips about the coming era of autonomous vehicles (AV). AVs are burning rubber in media of all kinds (you can find video of the blind man’s spin around the block here). Some of these stories address concerns about AVs and I don’t mean to discount them. Yet, AVs have an air of inevitability about them, don’t they? It’s not a question of “if” it happens, but “when.”To read this article in full, please click here
Linux provides a wide variety of commands for working with files — commands that can save you time and make your work a lot less tedious.Finding files
When you're looking for files, the find command is probably going to be the first command to come to mind, but sometimes a well-crafted ls command works even better. Want to remember what you called that script you were working on last night before you fled the office and drove home? Easy! Use an ls command with the -ltr options. The last files listed will be the ones most recently created or updated.$ ls -ltr ~/bin | tail -3

I just left another CIO meeting with a Fortune 100 prospect who was wondering, “why Silver Peak versus the 800-pound gorilla in the networking space that offers several different ‘SD-WAN’ offerings?” The challenge she faced wasn’t about whether it was the best solution or not - Silver Peak cruised through the technical evaluation, easily winning the technical recommendation. What she really wanted to know is if she should trust the future of her next Wide Area Network (WAN) to a private company.This is a challenge we at Silver Peak face in seemingly every account we earn. The technical part isn’t the hard part, as we consistently win product evaluations and bakeoffs. What we have to prove is that it’s actually less risky to choose Silver Peak as the platform to build their next generation WAN on when compared to trying to stretch a Cisco router-centric model.

We’re hearing a lot these days about how CIOs are becoming more strategic partners with executive management – how IT is moving closer to the core of the business and earning a seat at the table in strategy discussions. I’m a bit skeptical that it’s happening on anything like a broad scale. It’s certainly true that there’s an awareness that IT is “mission critical,” that you absolutely cannot afford to have the network go down even for a second, or a security slip-up that results in losing hundreds of thousands of credit card records. Those are hugely important discussions, but they’re not seen as directly related to business outcomes.Many in the C-Suite still see at least a percentage of IT expenditures as almost like a tax on the business. When IT leaders get into investment conversations, their colleagues are often about as excited as the rest of us are when it’s time to pay our personal income tax bill.To read this article in full, please click here

Test results from recent Low Earth Orbit internet satellite launches are starting to come in—and they're impressive.OneWeb, which launched six Airbus satellites in February, says tests show throughput speeds of over 400 megabits per second and latency of 40 milliseconds. Further, the future internet service provider (ISP) says a satellite re-alignment will offer southern U.S. coverage sooner than originally thought.Also read: The hidden cause of slow internet and how to fix it

Oracle OpenWorld 2019 is the platform for countless software announcements, but since 2010 the company has been in the hardware business thanks to the Sun Microsystems purchase, and the company remains committed to delivering integrated hardware and software systems.Proving the point, the company took the wraps off the Oracle Exadata X8M designed for acceleration of Oracle’s database applications, featuring new data analytics and business intelligence features along with Oracle's newfound religion on automation.The new Exadata X8M server platform uses second-generation Xeon Scalable processors and Intel's Optane DC persistent memory to accelerate performance. That's a big win for Intel, which is seeing quite a bit of momentum for AMD's Epyc processor. And it's another win for Optane, which pretty much every server vendor supports.To read this article in full, please click here
Carriage returns go back a long way – as far back as typewriters on which a mechanism or a lever swung the carriage that held a sheet of paper to the right so that suddenly letters were being typed on the left again. They have persevered in text files on Windows, but were never used on Linux systems. This incompatibility sometimes causes problems when you’re trying to process files on Linux that were created on Windows, but it's an issue that is very easily resolved.The carriage return, also referred to as Ctrl+M, character would show up as an octal 15 if you were looking at the file with an od octal dump) command. The characters CRLF are often used to represent the carriage return and linefeed sequence that ends lines on Windows text files. Those who like to gaze at octal dumps will spot the \r \n. Linux text files, by comparison, end with just linefeeds.To read this article in full, please click here
When Microsoft launched Azure as a cloud-based version of its Windows Server operating system, it didn't make it exclusively Windows. It also included Linux support, and in just a few years, the number of Linux instances now outnumbers Windows instances.It's nice to see Microsoft finally shed that not-invented-here attitude that was so toxic for so long, but the company's latest move is really surprising.Microsoft has partnered with a company called Skytap to offer IBM Power9 instances on its Azure cloud service to run Power-based systems inside of the Azure cloud, which will be offered as Azure virtual machines (VM) along with the Xeon and Epyc server instances that it already offers.To read this article in full, please click here
Multi-user MIMO allows multiple Wi-Fi devices to simultaneously receive multiple data streams. For example, a wireless access point (AP) can send data to four different Wi-Fi devices at the same time. MU-MIMO can greatly increase the network's throughput and is a real asset for high density networks.If you aren’t familiar, MIMO stands for multiple input multiple output. The technology has evolved over the years since the debut of the single-user mode (SU-MIMO), which was introduced a decade ago with the 802.11n wireless standard.To read this article in full, please click here
As the cloud era meets the demands of digital transformation, networks must change. That means for enterprises, they must become simpler, said Juniper CEO Rami Rahim, speaking at the company's annual industry analyst conference last week.The past five years has seen more innovation in networking than in the previous 30. Things such as SD-WAN, multi-cloud, Wi-Fi 6, 5G, 400 Gig, and edge computing are on the near-term horizon for almost every company. While all of those technologies have enabled the network to do so much more than ever before, their complexity has also risen.To read this article in full, please click here
