With a cold on one side and a complete Internet connection meltdown on the other, I've been having a heck of a time keeping up with my email. Still, before my ISP, Bell South, hosed my DSL connection and my cold medicine knocked me out, I got a message asking: "What's the deal with those 'delta' releases for SUSE 10.1? I can't get them to work."

With the pervasiveness of 64-bit architectures, it's more important than ever that your Linux® software be 64-bit ready. Learn how to avoid portability pitfalls when making declarations and assignments, bit shifting, typing, formatting strings, and more.

If your laptop computer is a complement to your desktop machine, you're probably well aware of the need to synchronize data between the two. When you're in the middle of a big project and know you're going to be spending the afternoon in a doctor's waiting room or on an airplane, it's nice to be able to quickly transfer your project files--and maybe your email and contacts--to the laptop, then vice-versa when you return to your desk. This article will show you two ways to accomplish this on GNU/Linux-based machines.

This tutorial presents the author’s practical experience with writing Linux device drivers to control custom-designed hardware. The tutorial starts by providing an overview of the driver writing process, and describes several example drivers provided with this tutorial [4]. The reader is encouraged to experiment with those example drivers on their own x86 system, as it provides the best learning experience.

This article explains how a small, Utah-based company used asynchronous Javascript and XML (AJAX) to add advanced features to the user interfaces in its Linux-based cameras.

In this tutorial I will describe how to set up a highly available NFS server that can be used as storage solution for other high-availability services like, for example, a cluster of web servers that are being loadbalanced. If you have a web server cluster with two or more nodes that serve the same web site(s), than these nodes must access the same pool of data so that every node serves the same data, no matter if the loadbalancer directs the user to node 1 or node n. This can be achieved with an NFS share on an NFS server that all web server nodes (the NFS clients) can access.

In the previous column, we found that parallel programs for clusters have very subtle differences and their efficiency requires careful examination of the code. In this article, we will see what a typical parallel program looks like and how it is executed on a cluster. Be warned, however, there is a bit of gentle mathematics in this column. It will not hurt, we promise.

In this HowTo I will describe the steps to be taken to prepare a server for OpenVZ virtual machines on Debian 3.1 (Sarge) 32Bit Linux. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernal patch is licensed under the GPL license, and the user-level tools are under the QPL license.

There are key utilities, command line chains, and scripts that are used to simplify different processes. Some of these tools come with the operating system, but a majority of the Unix tricks come through years of experience and a desire to ease the system administrator's life. The focus of this article is on getting the most from the available tools and insight across a range of different UNIX environments.

Getting Linux to run on a USB Drive may easily seem to be an overwhelming process, but we put together a very simple guide that an absolute novice could follow.

We have written a range of guides highlighting excellent free books for popular programming languages. Check out the following guides: C, C++, C#, Java, JavaScript, CoffeeScript, HTML, Python, Ruby, Perl, Haskell, PHP, Lisp, R, Prolog, Scala, Scheme, and SQL.
