Building an Ultra-Low-Power File Server with the Trim-Slice

By Daniel Bartholomew 

For the past several years, I've used a custom-built file server at my house. I've upgraded it many times, but it began life, as near as I can recall, in April 2000. When I say "upgraded", I mean the internals have been swapped completely on at least two occasions among other things. more>>

SSH Tunneling - Poor Techie's VPN

By Jayson Broughton 

"If we see light at the end of the tunnel, it is the light of the oncoming train" ~ Robert Lowell. Oh yes, another good quote. This post is on SSH tunneling, or as I like to call it 'Poor Man's VPN'. Contrary to the sysadmin's popular belief, SSH tunneling actually can be very valuable use for both techies and home users. more>>

Learning to Program the Arduino

By Amit Saha 

This article should acquaint you with basic Arduino programming and show you how to write programs that interact with objects in the real world.

Advanced Firewall Configurations with ipset

By Henry Van Styn 

iptables is the user-space tool for configuring firewall rules in the Linux kernel. It is actually a part of the larger netfilter framework. Perhaps because iptables is the most visible part of the netfilter framework, the framework is commonly referred to collectively as iptables. iptables has been the Linux firewall solution since the 2.4 kernel. more>>

Swap Your Laptop for an iPad + Linode

By Mark O'Connor 

Ditch your laptop and code in the cloud—it's easier than you'd think.

On September 19, 2011, I said goodbye to my trusty MacBook Pro and started developing exclusively on an iPad + Linode 512. This is the surprising story of three months spent working in the cloud. more>>

EPUBReader

By Shawn Powers 

With our recent transition to a digital-only format, it's now possible to consume Linux Journal in a number of ways. For those so inclined, it's even possible to print each issue and bind it into a paper magazine. (The PDF lends itself quite nicely to that in fact) Electronically speaking, however, it's hard to beat the .epub/.mobi editions. more>>

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
