There's an old saying in the real-estate business that the three most
important things in a property are location, location and location.
We can assume this is still true when it comes to real estate,
but it also is increasingly true when it comes to Web applications. more>>
If you're like me (and you're a Linux Journal reader, so you may actually
be like me), you probably rotate through your cell phones and/or tablets
every couple years. These little devices are so convenient and have
been consistently dropping in price, while their power continues to go up,
so you may have a few older devices sitting in a drawer. more>>
I am a visual learner. When I try to teach something, I naturally like
to use visual examples. That usually involves me working for hours to
create flowcharts in Google Docs using the drawing program. Yes, it
works, but it's a very cumbersome way to create a flowchart. Thankfully,
I recently discovered Lucidchart.
Text expansion and hotkey automation are the sort of things you don't
realize you need until you try them. Those of you who ever have played with
system settings in order to change the function of a keystroke on you
system understand the value of custom hotkeys.
Sometimes a new piece of code turns out to be more useful than its author
suspected. Alejandra Morales recently came
out with the Cryogenic Project
as part of his Master's thesis, supervised by Christian Grothoff. The idea
was to reduce energy consumption by scheduling input/output operations in
I use my phone more often to log in to on-line accounts than I use a
computer. I can assure you it's not because typing passwords on a tiny
keyboard is fun. For most of us, we just have instant access to our phones
at any given time during the day. more>>
I'm writing this in a hotel room entered through two doors. The hall door
is the normal kind: you stick a card in a slot, a light turns green, and the
door unlocks. The inner one is three inches thick, has no lock and serves a
single purpose: protection from an explosion. more>>
Gah, so frustrating! Ten years ago I wrote a rather popular book called
Wicked Cool Shell Scripts, and I'm working on a new
Tenth Anniversary release. There are lots of new scripts, entirely new chapters and
updates to the older stuff. more>>
Vibrations and wave motions describe many different physical systems. In
fact, most systems that dissipate energy do so through waves of one form
or another. In this article, I take a look at gvb (Good ViBrations, http://www.pietrobattiston.it/gvb), a Linux
application you can use to visualize and model wave motion and

Ansible is an open-source automation tool developed and released by Michael
DeHaan and others in 2012. DeHaan calls it a "general-purpose automation
pipeline" (see Resources for a link to the article "Ansible's Architecture: Beyond Configuration
We're all familiar with the idea of virtualized computers. Not only
are they a great way to better utilize resources in a server room,
but they also allow you to create and destroy servers in the blink of an
eye. That's perfect for a lab or training environment. Unfortunately,
it's always taken a rack of actual hardware to create a training lab
for Cisco hardware. more>>
As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.
Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.
In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
