Think Small  

Single-board computers, such as the Raspberry Pi, are very low cost and low power, yet are complete systems suitable for personal and educational projects. But are they HPC-worthy?

The Final Technology Frontier – You  

I've watched many things drop from sight during my lifetime. Some are simply reminders of days past, such as mailboxes on the street, pay telephones, and vinyl record albums. Some of the innovations that have disappeared, however, have had a more profound effect on me, such as rotary dial phones that gave way to push-button phones, compact discs that gave way to downloadable music, and camera film that gave way to digital blips on a computer screen. The point is that all of the innovations I've seen during the past couple of decades have been made to make my life easier or richer in some obscure way. But the next generation of inventors isn't just thinking about the external environment: They have turned their sights toward you and me – in the years ahead, the consumers won't just use the product, they will become part of the product.

Mr. Efficient  

The superior "Earliest Deadline First" task scheduling method has been part of Linux since kernel 3.14.

Dream Start  

Microsoft's WIMBoot lets you run Windows 8.1 from a compressed file on solid state drives.

Close Watch  

Icinga on the Raspberry Pi monitors your network, letting you see the good, the bad, and the ugly, so you can address problems proactively.

TCP Camouflage  

Port scans for finding vulnerable services are nothing new, and port knocking as a defense has been around for a while, too. TCP Stealth tries to do something similar, but it takes a more sophisticated approach. We take a closer look.

It's in the Blend  

Java is not just about beans, it's also about the huge variety of libraries and frameworks that keep the language alive. If you feel like a bit of blending, Java integrates many flavors of third-party languages.

Taking Precautions  

The software market offers numerous solutions for tracking the status of Windows computers. However, if you only need to monitor individual computers outside the domain, you can use PowerShell to collect basic health and performance data.

Node Check  

A collection of single- and multinode performance benchmarks is an excellent place to start when debugging a user's application that isn't running well.
