10 questions to ask when selecting enterprise IoT solutions

REVIEW: 6 enterprise-scale IoT platforms

There's little need to tell anyone in IT that the Internet of Things (IoT) is a big deal and that it's growing insanely fast; BI Intelligence estimates that there will be some 23.3 billion IoT devices by 2019. As IoT support becomes more of an enterprise concern, there are four key issues about enterprise IoT (EIoT) deployments to consider: The sheer number of enterprise IoT endpoint devices – There will be 1 billion by 2019. The frequency of data generated IoT devices – IDC estimates that by 2025, an average connected person anywhere in the world will interact with connected devices nearly 4,800 times per day or one interaction every 18 seconds. The incredible volume of IoT data – Of the 163 zettabytes (that's 1021bytes) of data that will be created in 2025, IDC estimates that 60% will be from IoT endpoints and half of that (roughly 49 zettabytes) will be stored in enterprise data centers. The challenges of maintaining security for your device constellation – IDC estimates that by 2025, 45% of the stored enterprise data will be sensitive enough to require being secured but will not be.

7 free networking tools you must have

"I am all about useful tools. One of my mottos is 'the right tool for the right job.'" –Martha StewartIf your "right job" involves wrangling computer networks and figuring out how to do digital things effectively and efficiently or diagnosing why digital things aren't working as they're supposed to, you've got your hands full. Not only does your job evolve incredibly quickly becoming evermore complex, but whatever tools you use need frequent updating and/or replacing to keep pace, and that's what we're here for; to help in your quest for the right tools.[ Don’t miss customer reviews of top remote access tools and see the most powerful IoT companies . | Get daily insights by signing up for Network World newsletters. ] We've done several roundups of free network tools in the past, and since the last one, technology has, if anything, sped up even more.

14 Linux apps that will change how you work

Linux productivity toolsThe sheer number of Linux apps available today is mind boggling and one category in particular has exploded over the last few years: productivity tools. While there are a few well-known apps such as LibreOffice and NeoOffice (both forks of OpenOffice), there are many more tools that can make your work easier. Here are a variety of killer Linux office productivity apps you may not know about. (Note: many of them are also available for macOS and Windows, so if you have to hop between operating systems, you can keep at least a semblance of consistency.)To read this article in full, please click here

Gravityscan, keeping WordPress sites safe

If your website, in common with roughly 25% of all websites, is running WordPress then it's pretty much certain that it's being constantly attacked. WordPress is to hackers what raw meat is to jackals because unless sites are assiduously maintained, they quickly become vulnerable to a huge number of exploits.The root cause of this vulnerability is WordPress' ecosystem of complex core software augmented by thousands of third party developers whose themes and plugins are often buggy and not quickly (or often, never) updated to fend off known security problems. Add to that many site owners being slow to update their core WordPress installation and you have an enormous and easily discovered collection of irresistible hacking targets.To read this article in full or to leave a comment, please click here

10 more killer Raspberry Pi projects

Prolific developers of Raspberry PiImage by Mark GibbsWelcome to the third collection of Killer Raspberry Pi Projects. Our first and second collections were such a hit that we just had to produce another. There are so many interesting applications of the Raspberry Pi it's getting hard to pick and choose but, once again, we've sorted the wheat from the chaff to bring you ten more projects that embody the creativity and enthusiasm that defines the Raspberry Pi market. We have animatronic horror driven by Alexa, toy cars driven by deep learning, a couple of display projects, and cats recognized and monitored by Raspberry Pis. In short, more RPi goodness than you can shake a stick at.To read this article in full or to leave a comment, please click here

Raspberry Pi, ultrasonics, and music

My son is a musician and he’s mentioned several times that he’d like to get an instrument called a theremin. If you haven’t encountered this instrument before, it consists of an antenna that the theraminist (yes, that is a real word) waves their hand around. The device responds with a musical tone that’s dependent on how close the theraminist’s hand is to the antenna. How does it actually work? According to Wikipedia: The theremin uses the heterodyne principle to generate an audio signal. The instrument's pitch circuitry includes two radio frequency oscillators set below 500 kHz to minimize radio interference. One oscillator operates at a fixed frequency. The frequency of the other oscillator is almost identical, and is controlled by the performer's distance from the pitch control antenna. / The performer's hand acts as the grounded plate (the performer's body being the connection to ground) of a variable capacitor in an L-C (inductance-capacitance) circuit, which is part of the oscillator and determines its frequency.To read this article in full or to leave a comment, please click here

What’s in your home’s basement? Bet it’s not a mainframe.

Over the years I've been tempted to buy all sorts of ridiculous things from sites such as Recycled Goods and eBay and, for various reasons such as lacking enough room (and spousal approval) to get a rotovap setup going in the kitchen, I've managed to restrict myself to a few small, reasonably sane acquisitions. Other people, for example, Connor Krukosky, not only laugh at temerity such as mine but go big with hardly a second thought.A couple of years ago, at the age of 18, Krukosky who has what we'll call "a passion" for collecting and restoring vintage computers, spotted a posting on a mailing list announcing that an decade-old IBM Z890 mainframe was being sold by Rutgers University and the bidding was at a measly $100. Krukosky was immediately interested and bid, winning the beast for the handsome sum of $237.39.To read this article in full or to leave a comment, please click here

10 more killer Raspberry Pi projects (Collection 2)

Killer Raspberry Pi ProjectsImage by Gareth Halfacree / flickrIn the last installment of Killer Raspberry Pi Projects, the focus was on projects that produced a final device or system. In this installment, I’m going to cover a few cool projects along with some tools used to build other projects. I've also included some Raspberry Pi Zero projects that are becoming more numerous as the board and its successor, the Raspberry Pi Zero W, become more available (the latter is still much like hens' teeth).To read this article in full or to leave a comment, please click here

PodPi makes STEM education exciting!

When I was a kid, the way science was taught was, on the whole, pretty boring … well, except for chemistry where the class chemistry wiz would “accidentally” blow things up or make horrible smells every now and then. Science was a class to get through with gritted teeth and even today, getting kids interested in STEM education (Science, Engineering, Technology, and Mathematics) is still difficult. The problem is how to make topics that appear dry and complicated into something kids can get excited about. Five years ago, Stéphane Côme, the founder, chairman, and chief technology officer of LCS Technologies, a consulting firm specializing in Oracle database wrangling, decided that he wanted to give back to the community and that his focus should be on inspiring children to get involved with computers and software. Côme told me he started off by establishing a Meetup group to teach children and their parents through hands-on technology projects:To read this article in full or to leave a comment, please click here
