Hack and /: Automatically Lock Your Computer

If you've ever worked with pranksters, you've probably come across this classic office prank. First, the unsuspecting victim leaves his computer and goes to lunch or a long meeting and doesn't lock his screen. The prankster then takes a screenshot of his current desktop, hides all the desktop icons and any taskbars, and sets the background to be the screenshot the prankster just took. more>>

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

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

"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'.

Learning to Program the Arduino

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

Work the Shell - What Day Is That Date in the Past?

In a previous article, we started a script that worked backward from a day and month date and figured out the most recent year—including possibly the current year—that would match that date occurring on that particular day. more>>

Advanced Firewall Configurations with ipset

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>>

Mustache.js

In previous articles, I've looked at a number of uses for JavaScript, on both the server and the client. I hope to continue my exploration of such systems, particularly on the client side, in the coming months. more>>

Swap Your Laptop for an iPad + Linode

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>>

Remote Viewing-Not Just a Psychic Power

Most people today are used to having a nice, intuitive graphical environment when they sit down to use a computer. Gone are the days of using a DOS machine or being lucky enough to have a dial-up account at 300 baud on a UNIX mainframe. more>>

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment.

Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
