In many scientific disciplines, the research you may be doing is completely new. It may be so new that there isn't even any instrumentation available to make your experimental measurements. In those cases, you have no choice but to design and build your own measuring devices. more>>

The other day in the Linux Journal IRC room (#linuxjournal on Freenode), I was whining to the channel about no-ip.com deleting my account without warning. My home IP address hadn't changed in a couple months, and because there was no update, it appeared abandoned. more>>

What if, just like Bill Murray in Groundhog Day, you could wake up to a fresh and identical development environment completely free of yesterday's experiments and mistakes? Vagrant lets you do exactly that. more>>

Many free software fans, if they were like me, breathed a collective sigh of relief when the Android operating system hit the market. more>>

Everyone planning and building Web solutions with Drupal benefits from understanding what a "hook" is—and why Drupal is not a CMS. more>>

New Linux users often ask me "what is the best way to learn about Linux?" My advice always comes down to this: install and use Linux (any distribution will do but something stable works better), and more>>

As Linux users, we tend to take programs like GIMP for granted. Thankfully, as of version 2.8.2, GIMP is available as a native application for OS X! Because everyone reading this most likely is familiar with how awesome GIMP is for photo editing, it's worth mentioning there is another open-source photo-editing application for OS X named Seashore. more>>

Like many folks, I received a shiny new Nexus 7 tablet for Christmas. This brought me great joy and excitement as I began to plot my future paperless life. For most of the evening and an hour or so the next day, I was sure the new Android tablet would change my life forever. Sadly, it wasn't that easy. more>>

JavaScript has had a long-standing monopoly on client-side Web programming. It has a tremendously large user base, and countless libraries have been written in it. Surely it is the perfect language with no flaws at all! Unfortunately, that is simply not the case. more>>

When the Space Shuttle program shut down, I have to admit, it deflated my excitement about space exploration just a bit. Although it's not fair to pin the future of manned missions to space on a fleet of aging crafts built in the 1980s, the Space Shuttle represented the latest step in a process that would get us to other planets. more>>

Adobe Systems, the world's leading supplier of graphical software, is gradually shifting its business to a subscription model, baiting customers with features and tools available only to Creative Cloud subscribers. more>>

Linux enthusiasts might think the idea of running a Linux virtual machine on Microsoft's Azure service is like finding a penguin sun tanning in the Sahara. Linux in the heart of the Microsoft cloud? Isn't that just wrong on so many levels? more>>

Previously, I erroneously titled my column as ""SIGALRM Timers and Stdin Analysis". It turned out that by the time I'd finished writing it, I had spent a lot of time talking about SIGALRM and how to set up timers to avoid scripts that hang forever, but I never actually got to the topic of stdin analysis. more>>

This tutorial provides a general description of updating Linux-based firmware and illustrates it with some specific implementations. First, consider the sections of the memory system (Figure 1) and parts of memory that should be updated while transferring software to a new version. more>>

Virtualization is now a staple of the modern enterprise. As more and more shops switch to the virtual paradigm, managing those new virtual resources is a critical part of any deployment. For admins using Microsoft- or VMware-based hypervisors, powerful management tools are available to keep their virtual houses in order. more>>

My last several articles have covered lots of software for doing research in the sciences. But one important area I haven't covered in detail is the resources available for teaching the next generation of computational scientists. To fill this gap, you can use the code provided through the Open Source Physics project. more>>
