Olimex is a Bulgarian company known for its innovative hobbyist
products. It has a wide array of microcontroller-based products, ranging
from the small Arduino clones to the very able system that has the Allwinner
A13 microcontroller as its brain. In this article, I describe
how you can create a working Linux system for the Olinuxino A13 and Olinuxino
A13Micro from scratch.
"Check Engine Soon"—that little orange light on your car's instrument
panel is possibly one of the more annoying things about modern
automobiles. Ever had it pop on during a trip and wonder whether it was just
something mundane, like your gas cap being loose, or whether it's something
deathly serious and a piston could come shooting out the side of your
engine block at any time? more>>
In my last article, I started discussing Compojure, a Web framework written
in the Clojure language. Clojure already has generated a great deal
of excitement among software developers, in that it combines the
beauty and expressive elegance of Lisp with the efficiency and
ubiquity of the Java Virtual Machine (JVM). more>>
In a previous article, I discussed Apache Tomcat, which is the ideal way to run
Java applications from your server. I explained that you can run those
apps from Tomcat's default 8080 port, or you can configure Tomcat to use
port 80. But, what if you want to run a traditional Web server
Java apps on port 80? The answer is to run a reverse proxy.

Just because you're not on Linux doesn't mean you can't have awesome open-source tools. I was having a conversation with a friend and reader (Don
Crowder: @eldergeek) on Twitter the other day about music theory. Yes,
I'm not just a computer nerd, but a music/math nerd too. Anyway after our
conversation, I started looking for an open-source program for creating
sheet music. more>>
Android, as a platform, is one of the fastest growing on the planet. It
is available on smartphones and a series of different tablet sizes. Most
devices also include a full spectrum of sensors that are available to
programs you install, so it's a very inviting platform
for development. more>>
Although many people are excited about the hardware-hacking possibilities
with the Raspberry Pi, one of the things that interests me most is
the fact that it is essentially a small low-power Linux server I can
use to replace other Linux servers I already have around the house. more>>
Embedded developers working on kernels or bare-metal programs often go
through several development cycles. Each time the developer modifies the
code, the code has to be compiled, the ELF (Executable and Linkable
Format)/kernel image has to be copied onto the SD card, and the card
then has to be transferred from the PC to the development board and
Don't get me wrong, I love The GIMP. We all love The GIMP, as our Readers'
Choice awards show this month. If I'm being completely honest, however, I
rarely have the need for such a powerful application. Usually, regardless
of what computer system I'm on, I pick Pixlr as my image editing program.
Molecular dynamics computations make up a very large proportion of
the computer cycles being used in science today. For those of you who
remember chemistry and or thermodynamics, you should recall that all of
the calculations you made were based on treating the material
in question as a homogeneous mass where each part of the mass simply has
the average value of the relevant properties. more>>
I've mentioned geocaching before, but if you've never taken the time
to go out and do it, you're really missing out. Whether you're dragging
your family through two feet of snow in the middle of the woods (yeah, I
did that last year, I'm still not sure they've forgiven me) or following
your GPS around a parking lot looking for a tiny micro-cache, geocaching
is fun. more>>
If, like me, you've jumped onto the Plex bandwagon with both feet,
you've probably discovered how difficult it is to make a standalone Plex
player. Sure, you can install an entire OS, then auto-start the Plex
program in full screen, but it's not as simple as installing the XBMC
distro, or even OpenELEC. If you own a Raspberry Pi, that has all changed.
Not even Mighty Big Blue can stop a hurricane. But. IBM and Marist College are testing a new cloud computing innovation that could help prevent disruptions in voice and data communications services caused by hurricanes and other natural disasters.
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.
