Navigating man pages in Linux

Man pages provide essential information on Linux commands and many users refer to them often, but there’s a lot more to the man pages than many of us realize.You can always type a command like “man who” and get a nice description of how the man command works, but exploring commands that you might not know could be even more illuminating. For example, you can use the man command to help identify commands to handle some unusually challenging task or to show options that can help you use a command you already know in new and better ways.Let’s navigate through some options and see where we end up.Using man to identify commands The man command can help you find commands by topic. If you’re looking for a command to count the lines in a file, for example, you can provide a keyword. In the example below, we’ve put the keyword in quotes and added blanks so that we don’t get commands that deal with “accounts” or “accounting” along with those that do some counting for us.To read this article in full, please click here

The Week in Internet News: Goodbye Yellow Brick Road

The FBI weighs in, again: The U.S. FBI, which has complained for years about the lack of access to encrypted communications, isn’t yet ready to call for legislation that would force tech companies to let police in, FCW.com reports. During a recent congressional hearing, Rep. Matt Gaetz (R-Fl.) asked if there was “meaningful legislation that Congress should consider so that technology partners have a yellow brick road to work with the government.” The decision “should be made by the American people through their elected representatives, not through one company making a business decision on behalf of all of us,” FBI Director Christopher Wray said.

Community networks rising: CircleID has a blog post featuring broadband predictions for 2020, including expectations that community broadband networks will see a “massive surge.” The prediction: “As the public becomes better acquainted with broadband policy issues thanks to the election cycle and the growing digital disparity, we are seeing that more and more communities are taking matters into their own hands.”

Super speedy: In related news, the UTOPIA Fiber network, boasting the fastest broadband speeds in the U.S., has expanded in Utah, KSL.com reports. The fiber network offers Continue reading

ONIE 2020 update

Even if it’s free, you still have to sell it. Yet a solution only works if people want to use it.

Last year I became the project lead for ONIE: the Open Network Install Environment. If you’re unfamiliar with this, ONIE is an open source project for installing operating systems on network switches. Manufacturers will start with the core ONIE code, add support for their new hardware (so that their new switch has an industry-standard way of installing an operating system) and then submit those changes back to the ONIE project.

As of 2020, this has happened over two hundred times, along with with well over a thousand contributions of bug fixes and improvements. As these changes are submitted, they need to be quality checked and tested to make sure they build cleanly. When I became the project lead, I had already been working on build tools at Cumulus Networks and decided my first contribution was going to be creating a standard build environment for ONIE that could be deployed anywhere.

This went great until my final test of the new build environment, which was to build every platform ONIE supported, and it didn’t go as well as I’d hoped. Continue reading

Future ‘smart walls’ key to IoT

IoT equipment designers shooting for efficiency should explore the potential for using buildings as antennas, researchers say.Environmental surfaces such as walls can be used to intercept and beam signals, which can increase reliability and data throughput for devices, according to MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL).Researchers at CSAIL have been working on a smart-surface repeating antenna array called RFocus. The antennas, which could be applied in sheets like wallpaper, are designed to be incorporated into office spaces and factories. Radios that broadcast signals could then become smaller and less power intensive.To read this article in full, please click here

Who should lead the push for IoT security?

The ease with which internet of things devices can be compromised, coupled with the potentially extreme consequences of breaches, have prompted action from legislatures and regulators, but what group is best to decide?Both the makers of IoT devices and governments are aware of the security issues, but so far they haven’t come up with standardized ways to address them.[Get regularly scheduled insights by signing up for Network World newsletters.] “The challenge of this market is that it’s moving so fast that no regulation is going to be able to keep pace with the devices that are being connected,” said Forrester vice president and research director Merritt Maxim. “Regulations that are definitive are easy to enforce and helpful, but they’ll quickly become outdated.”To read this article in full, please click here

BrandPost: Stop Over-Spending on Underutilized Resources: The Future of the Data Center is Composable Disaggregated Infrastructure

The only thing constant is change, and data centers are no exception. As data architects attempt to anticipate future data center needs – while delivering the required SLAs to the business – the solution is often to over-provision resources so that the infrastructure can absorb any changes or periodic spikes in demand.But today change happens much more frequently, whether it’s onboarding new applications or reaching new heights in data growth. Most often, organizations expect immediate implementation of those changes In today’s environment of flat or declining budgets, IT can no longer afford to over-provision its way.Composable disaggregated infrastructure (CDI) enables organizations to respond to changes almost instantly while at the same time reduce costs. This in turn helps IT better align changing business needs and allocate IT resources on the fly.To read this article in full, please click here

Vetflare, Cloudflare’s Military Veteran Employee Group Launches

“Diversity leads to better outcomes… better decisions, increased innovation, stronger financial returns, and a great place to work for everyone” said Janet Van Huysse, Head of People at Cloudflare during our Q1-2020 kickoff. Veterans, people who have served in the military, are a vital element of a diverse workforce. We come in diverse shapes, sizes, colors, genders, and orientations. We bring diverse skillsets, experiences, and perspectives.  

If you haven’t served in the military and haven’t worked with many veterans, here are some of the things that you can expect from your colleagues or direct reports that are veterans.

Veterans know what it means to SERVE. Indeed, it is a truism that living in service to others is a life well-lived, and that service to others is a foundation of esprit de corps. Though relatively few of us have seen combat, we have all signed a blank check to our nation made payable for any amount, up to and including our lives. This is what it means to become part of something bigger than oneself. This translates to putting our common shared interests ahead of our personal interests even when that means becoming an instrument of a foreign policy we Continue reading
