Call For Articles - HPC (High Performance Computing)
Does a system with dual Quad Core processors, 128GB of RAM, and a Tera-Byte RAID array seem pretty tame to you? Does writing a program with a dozen threads seem about as complex as an abacus to you? Does a database with a million records seem like something you'd put on a USB memory stick? Do you know who John Backus was? Are you cleared for ridiculous by the US Government?
If you answered yes to any of these questions then you're probably involved in some type of High Performance Computing (HPC). If it involves Linux or Open Source we need you to write about it!
So drop that slide-rule, put down that triple Espresso, tell the CEO of American Express that you'll call him back later and start thinking about what you can write!

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
