What’s in a Raspberry Pi name? How to rename your RPi under Raspbian

A common task after setting up Raspbian-based Raspberry Pi systems is to change the machine’s name (the hostname) because it will, by default, be set to "raspberrypi".While this may not be an issue if you have only one RPi on your network, for anyone developing Internet of Things (IoT) systems where there are multiple RPi’s, it would obviously be desirable to give them more useful hostnames. You can change the hostname temporarily using the hostname command (note that you must use sudo otherwise the command will fail) but, once you reboot, the name will revert to what it was previously set to and what we usually want is to change the hostname permanently. There are a number of ways this can be achieved including using the hostname command in a shell script at startup which could perhaps be useful if you need a dynamically defined hostname but the method most often cited is by editing the hosts file, thusly:To read this article in full or to leave a comment, please click here

Thoughts on Theft

ShareArrows

It’s been a busy week for me. In fact, it’s been a busy few weeks. I’ve had lots of time to enjoy NetApp Insight, Cloud Field Day, and Storage Field Day. I’ve also been doing my best to post interesting thoughts and ideas. Whether it’s taking on the CCIE program or keynote speakers, I feel like I owe a debt to the community and my readers to talk about topics that are important to them, or at least should be. Which is why I’m irritated right now about those ideas being stolen.

Beg, Borrow, and Steal

A large part of my current job is finding people that are writing great things and shining a spotlight on them. I like reading interesting ideas. And I like sharing those ideas with people. But when I share those ideas with people, I make absolutely sure that everyone knows where those ideas came from originally. And if I use those ideas for writing my own content, I make special care to point out where they came from and try to provide the context for the original statement in the first place.

What annoys me to no end is when people take ideas as Continue reading

Using the Raspberry Pi to thwart the creepy clown menace

Like me, I suspect that you have been, in  turns, amused and puzzled by the recent outbreak of creepy clowns. But should you doubt the significance of this weirdness, realize that it’s not only a United States phenomena, it’s global! TIME just published an article titled The Creepy Clown Craze Is Now Taking Over the World while The Verge tried to be sort of rational with The 2016 clown panic: 10 questions asked and answered. But no matter how much the media deny it, this is a serious thing, people. You thought the zombie apocalypse was a big deal? The clownpocalypse could well be Trump-sized, as in yuuuuuuggggggge. But fear not, dear reader, I have the answer as to how we can stay safe from marauding clowns; it’s a device called the Clowntector, an early warning system to spot and locate clown activity so professional, anti-clown professionals can do their sacred duty.To read this article in full or to leave a comment, please click here

US may use sanctions to punish Russia for election hacking

The U.S. response to election-related hacks that the Obama administration now blames on the Russian government could include sanctions against that country. The administration has said that it has a range of options, including economic sanctions, to respond to Russian cyber attacks. On Friday, a Republican lawmaker said he would propose legislation to move those sanctions forward. Senator Cory Gardner, who represents Colorado, said his planned legislation would mandate that the U.S. government investigate Russian cyber criminals and sanction them when appropriate.To read this article in full or to leave a comment, please click here

Worth Reading: Three great lies of cloud computing

It’s elastic! It’s on-demand! It scales dynamically to meet your needs! It streamlines your operations, gives you persistent access to data, and it’s always, always cheaper. It’s cloud computing, and it’s here to save your enterprise. And yet, for all the promise of cloud, there are still segments of IT, such as HPC and many categories of big data analytics, that have been resistant to wholesale outsourcing to public cloud resources. At present cloud computing makes up only 2.4 percent of the HPC market by revenue, and although Intersect360 Research is forecast its growth at a robust 10.9 per year, that still keeps it well under 5 percent throughout the five-year forecast period. —The Next Platform

Both Apple and Microsoft take tumble in Gartner’s latest device forecast

Shipments of devices powered by Apple's and Microsoft's operating systems will end 2016 down from the year before. But Apple's will recover next year, while Microsoft's will continue to struggle toward growth, research firm Gartner said this week.In 2017, Apple's combination of iOS and macOS -- the former powering iPhones, the latter Macs -- will have taken second place from Windows on the devices shipped during the year. The gap between the two will widen slightly in 2018.According to Gartner, which provided Computerworld with its forecast broken out by operating system, Windows will power about 260 million devices shipped in 2016, a 12% decline year-over-year. The 260 million represents 11.2% of the total of 2.3 billion total devices, which overwhelmingly run Google's Android.To read this article in full or to leave a comment, please click here

Microsoft invites reporters to see what’s next for Windows 10—and maybe Surface

It’s official: Microsoft will hold an event in New York at the end of October where the company is expected to roll out a new Surface all-in-one PC. As we reported on Thursday, photos of a Surface-themed mouse and keyboard have already appeared in FCC filings.Interestingly, however, the term “Surface”—or even “hardware”—doesn’t appears anywhere on the invitation, which beckons reporters to a New York event on Oct. 26. Instead, Microsoft has invited reporters to “see what’s next for Windows 10,” which implies some sort of strategic update to the company’s software initiatives. “Imagine what you’ll do,” is written backwards on a window.To read this article in full or to leave a comment, please click here

Why Linux pioneer Linus Torvalds prefers x86 over ARM

Linux pioneer Linus Torvalds is a stand-up guy -- he says what he feels. There's no sugarcoating, and he'll admit to faults, like recent issues with the Linux 4.8 kernel.He was full of surprises at last week's Linaro Connect conference, when he was asked about his favorite chip architecture. He didn't blink before saying it was x86, not ARM.It may have been the long history of x86 with PCs that influenced his answer. There's little fragmentation of software and hardware with x86, and things just work.To read this article in full or to leave a comment, please click here

Microsoft’s Azure Stack TP2 Further Strengthens the Hybrid Azure Public / On-prem Environment

Azure Stack Technical Preview 2 (TP2) was announced at the Microsoft Ignite Conference at the end of September (2016), a MAJOR update from the TP1 release earlier this year focusing on extending the features and capabilities of Azure Stack as it progresses toward a formal release next year. A quick primer on what Azure Stack is for those reading up on Azure Stack for the first time.  In short, Azure Stack is Microsoft’s Azure public cloud environment that organizations can setup and run on-premise in their own datacenters.  Unlike something like Amazon Web Services that is a cloud-only solution where you have to import and export configurations and environments between your existing on-premise datacenter and AWS, Microsoft’s Azure Stack provides the same platform between the public cloud, hosted providers, and on-premise providers for the simplicity of building, configuring, and moving workloads between private and public clouds.  The Hybrid model of on-premise datacenters and public cloud services is a huge focus for enterprises that I covered in my initial February 2016 blog post introducing Azure Stack (http://www.networkworld.com/article/3037483/cloud-computing/truly-understanding-microsoft-s-azure-stack.html).To read this article in full or to leave a comment, please click here
