Raspberry Pi Roundup: Pi-se of the Machines, keeping the ball up, and GOOOOOOOOOOOOLLLLLLL

The Raspberry Pi is a computer of relatively modest raw capability, but it’s limited much more by our own creativity than it is by its hardware. We’ve seen Pis be everything from video game emulators to fantastic wedding proposal aides to fruit sniffers. Sure, it’s not a powerhouse, but that’s missing the point.To read this article in full or to leave a comment, please click here

DockerCon 2017: Moby’s Cool Hack sessions

Every year at DockerCon, we expand the bounds of what Docker can do with new features and products. And every day, we see great new apps that are built on top of Docker. And yet, there’s always a few that stand out not just for being cool apps, but for pushing the bounds of what you can do with Docker.

This year we had two great apps that we featured in the Docker Cool Hacks closing keynote. Both hacks came from members of our Docker Captains program, a group of people from the Docker community who are recognized by Docker as very knowledgeable about Docker, and contribute quite a bit to the community.

Play with Docker

The first Cool Hack was Play with Docker by Marcos Nils and Jonathan Leibiusky. Marcos and Jonathan actually were featured in the Cool Hacks session at DockerCon EU in 2015 for their work on a Container Migration Tool.

Play with Docker is a Docker playground that you can run in your browser.

Humans are (still) the weakest cybersecurity link

Humans remain the weak link in corporate data protection, but you might be surprised hat it isn't only rank-and-file employees duped by phishing scams who pose risks. Some companies are lulled into a false sense of cybersecurity by vendors. You read that right:Some enterprises believe the shiny new technologies they've acquired will protect them from anything.Just ask Theodore Kobus, leader of BakerHostetler’s Privacy and Data Protection team.

Worth Reading: Game of nodes

There’s a whirlwind of information on the topic of network commoditization. Seriously. Just search in your favorite search engine for “SDN,” “NFV,” or “telco cloud.” You will find dozens of open source projects, communities, forums, architectural definitions, standards, standard bodies, news articles, press releases, and blog sites dedicated to the aforementioned. With such a myriad of information, you’d think people out there would have a deep understanding of why these topics are creating so much noise. I make it a point to ask everyone I meet this simple question: “In a few sentences, what does telco cloud, NFV, or SDN mean to you?” In many cases, people generally just quote a bunch of buzz words — most of which I’m programmed to forget. Others jump into the “What” and “How” of these trends. Only a very few understand the “Why” and that there’s a fundamental challenge to the current business models in their industry. Something has to change. —New Stack

A vigilante hacker may have built a computer worm to protect the IoT

Is a vigilante hacker trying to secure your IoT device from malware? The mysterious developer behind a growing computer worm wants people to think so. The worm, known as Hajime, has infected tens of thousands of easy-to-hack products such as DVRs, internet cameras, and routers. However, the program so far hasn't done anything malicious.Instead, the worm has been preventing a notorious malware known as Mirai from infecting the same devices. It's also been carrying a message written from its developer.To read this article in full or to leave a comment, please click here

RESPONSE: 3 Hidden Lessons Behind Top Podcasts to Help Yours Stand Out

Thoughts from the Content Marketing Institute for budding podcasters were shared here. Here’s my response to the points that stood out to me.

CMI’s big idea #1.

“At first, format trumps talent.” And then later…“Avoid the race to the bottom of simply booking the biggest guests in your niche and meandering through an unplanned episode. Instead, find your format.”

Response. To record an effective show people will listen to, you need a plan, agreed. However, the article cites an example of a 15 minute long episode carved into blocks of minutes and seconds.

Perhaps that’s what you need when working against an ultra-tight timeline. However, an outline that provides structure should be adequate. Overly structuring a podcast is burdensome and can serve to stifle interesting conversation. Freedom is one of the benefits of podcasting.

Podcasting is NOT a digital regurgitation of radio, although many try to shoehorn podcasts into a radio format, because the radio business is what they understand. However, podcast content is different. Distribution is different. Listener consumption is different. Monetization is different.

And perhaps most importantly, timelines are fluid. 15 minute long podcasts are being created under an artificial time constraint that begs the question…why?

IDG Contributor Network: Unite and conquer your storage silos

If you’re a storage admin, it might seem like there’s a new flash storage system being pitched at your inbox every week. Maybe a few times a week, in fact. Perhaps you’re also investigating the cloud, and whether your enterprise would want to go with a hybrid, private or public cloud implementation. Chances are you already have a lot of storage in your infrastructure from past purchases, and when you add it all up, you could be sitting on quite a diverse collection of resources—and those resources may be significantly underutilized today.The diversity of storage types presents many options, which creates a real challenge for admins—but only because all those different resources could not be seamlessly connected until now. With storage solutions that deliver ultra-fast performance, such as all-flash arrays, some that save with low cost, cloud capacity for cold (inactive) data, and numerous other shared storage resources, most enterprise IT teams have the right resources to serve a wide variety of different data demands. The challenge is knowing what data needs which resource, then continually aligning data to the right resource as its needs change over time.To read this article in full or to leave a comment, Continue reading
