F5 offers new distributed cloud services for multicloud connectivity
Enterprise networking and application security company F5 is rolling out two new features to help businesses simplify different management tasks for today’s complex, multicloud environments.The core problem with multicloud is heightened complexity and its associated costs in management headaches and security weaknesses. Distributed deployments, the company said in its announcement of the new capabilities this week, decrease visibility into the workings of complex systems, making it easier for security holes to go unnoticed.F5’s new Distributed Cloud App Connect and Distributed Cloud Network are aimed squarely at addressing those problems via APIs designed to knit various applications and services together in a single-pane-of-glass management console.To read this article in full, please click here

Commercial quantum networks inch closer to primetime
As commercial availability of quantum computers moves closer to reality, researchers and vendors are investing in efforts to create quantum-secured networks.Quantum networks use entangled photons or other particles to ensure secure communications, but they are not, in and of themselves, used for general communication. Quantum networks are expensive and slow. And though nobody can listen in on the messages without breaking the entanglement of the photons, hackers can still try to attack the systems before the messages get into the quantum network, or after they leave it.Instead, quantum networks today are largely used for quantum key distribution (QKD), which uses quantum mechanics to secure the transmission of symmetric encryption keys. According to a June report by quantum industry analyst firm IQT research, the worldwide market for quantum networks will near $1.5 billion in 2027 and grow to more than $8 billion by 2031, and QKD will be the main revenue driver, followed by a rise in networks that use emerging quantum repeaters to connect quantum computers together and quantum sensor networks.To read this article in full, please click here

Cloud vs on-prem: SaaS vendor 37signals bails out of the public cloud
David Heinemeier Hansson, co-owner and CTO at SaaS vendor 37signals, is quitting the cloud and wants everyone to know about it. In a series of blog posts, Hansson has challenged the cloud business model, rebutted assumptions associated with cloud computing, and argued that the consolidation of power among hyperscalers is not necessarily a good thing.It might seem counterintuitive for a SaaS vendor to be publicly taking pot shots at the cloud and suggesting that other companies re-consider their cloud investments. Has Hansson, the creator of Ruby on Rails, gone off the rails?Hansson’s argument is simple: By pulling server workloads off the Amazon AWS infrastructure, purchasing new hardware from Dell, and running his business from a colocation facility, he will save millions of dollars.To read this article in full, please click here

Ethernet at 50: Bob Metcalfe pulls down the Turing Award
“Tickled pink” is Bob Metcalfe’s reaction to his latest accolade – the Association for Computing Machinery’s A. M. Turing Award for inventing and commercializing Ethernet. The award was announced today and will be presented at a ceremony June 10 in San Francisco.With his trademark sense of humor, Metcalfe says, “It’s a big surprise and a delight. I’ve received other awards in the past so I’m familiar with the notion that I have a new obligation to behave myself and live up to the standard of the award and be a role model based on that.”The award carries a $1 million prize. “My wife suggests I spend it on her,” Metcalfe quipped, before adding that he hasn’t worked out the details but will probably pour most of it into his family foundation (after he fills up his boat with diesel fuel).To read this article in full, please click here

Counting and modifying lines, words and characters in Linux text files
Linux includes some useful commands for counting when it comes to text files. This post examines some of the options for counting lines and words and making changes that might help you see what you want.Counting lines Counting lines in a file is very easy with the wc command. Use a command like that shown below, and you'll get a quick response.$ wc -l myfile 132 myfile What the wc command is actually counting is the number of newline characters in a file. So, if you had a single-line file with no newline character at the end, it would tell you the file has 0 lines,The wc -l command can also count the lines in any text that is piped to it. In the example below, wc -l is counting the number of files and directories in the current directory.To read this article in full, please click here

SD-WAN, SASE prove essential tools for Porsche’s electric-racecar success
The ninth season of Formula E World Championship racing is under way, with events slated this spring everywhere from Berlin to Jakarta to Portland, Oregon. Formula E has all of the thrills and spills of IndyCar or F1 racing—sleek aerodynamic vehicles, talented drivers, spirited competition. But there’s one key difference: the cars are electric.In traditional auto racing, the skills of the driver are certainly important, but so is the strategy of when to make a pit stop for fuel and tires as well as the real-time communication between driver and pit crew. Similarly, in Formula E the driver is the star of the show, but data analytics running in the background plays an important role.To read this article in full, please click here

Using the at command to schedule tasks on Linux
To schedule a command or script to run at some particular time, the at command is perfect and provides many options for specifying the time you want it to run. It will set the task up to be run whenever you specify, and you can view the scheduled tasks or even change your mind and cancel one of them as you see fit.The at command differs from cron in that it sets up a command or script to run only once, while cron allows you to set up commands or scripts to be run on a specified schedule – whether every day, once a week, a couple times a month or even just once a year.at command syntax Using the at command is relatively easy, though it has a lot of options, particularly on how you specify the time a task should be run. If you specify a time like shown below, the task will be set up to be run the next time you reach 15:27 (3:27 PM), whether that's today or tomorrow.To read this article in full, please click here

How network pros can fight being squeezed out of cloud decisions
There's a rumbling in the cloud as network professionals increasingly seek to reclaim what they believe is their rightful place in the enterprise management hierarchy.Network knowledge is now widespread within many other IT disciplines. "This means it's now sometimes easy for other teams to assume that they know all they need to know about networking, so they don't need to bother the network team," observes Josh Stephens, CTO of multi-cloud network automation provider BackBox.Network pros have unique perspectives. When it comes to multicloud decision-making, IT, cloud, cybersecurity, and network professionals all bring different perspectives and talents to the table. "IT teams have a deep understanding of the organization's overall technology, while cloud teams have expertise in cloud-based technology solutions, and cybersecurity teams have a thorough understanding of [cloud] security risks," says Dan Dulac, vice president of solutions strategy at network infrastructure provider Extreme Networks. Combining the insights of these experts, along with network professionals, is the best way for organizations to make informed decisions about their multicloud strategy, he says.To read this article in full, please click here
