Because you're a reader of Linux Journal, you probably already know that Linux has a rich virtualization ecosystem. KVM is the de facto standard, and VirtualBox is widely used for desktop virtualization. Veterans should remember Xen (it's still in a good shape, by the way), and there is also VMware (which isn't free but runs on Linux as well). more>>

Non-Linux FOSS: Vienna, Not Just for Sausages

LinuxJournal - Tue, 2015, Jun02 - 12:51

Although the technology itself has been around for a while, RSS is still the way most people consume Web content. When Google Reader was ended a few years back, there was a scramble to find the perfect alternative. You may remember my series of articles on Tiny Tiny RSS, Comma Feed and a handful of other Google Reader wannabes. more>>

Arduino workshop at Local Motors

AZ Loco - Fri, 2015, May29 - 15:35

A couple of weeks ago I attended a workshop on Arduino at Local Motors (LM). There were about 20 people, some with experience; others with none. Some brought their own Arduino kits and LM provided kits for us who did not have. First, there was a presentation on Arduino so that we could understand the basics. Then we started the workshop; our first exercise was to blink a LED. In Arduino terms, you enable one pin as output, then you loop to set the value to 0 and 1. Here's the code:

// Pin 13 has a LED connected on most Arduino boards.
int led = 13;

// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);

// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second

I installed the Arduino IDE (version 1.6.4) on my laptop (14.04) sudo apt-get install arduino arduino-core so I could interface with the board which just connects to a USB port. LM provided breadboards so we could try various schematics, blink 2 LEDs with variable timing, control motors, etc. The LM people were very helpful. I plan to go to the next workshop, it was fun.

My Humble Little Game Collection

LinuxJournal - Thu, 2015, May28 - 12:52

I currently have the flu. Not the "sorta queasy" stomach flu, but the full out Influenza with fever, aches and delirium-ridden nightmares. Bouts of crippling illness tend to be my only chance to play games. Thankfully, since I'm such a terrible gamer, being sick doesn't really hurt my skills very much! more>>

New Linux Based OS Brings Internet of Things Closer to Reality

LinuxJournal - Wed, 2015, May27 - 11:16

The "Internet of Things," or IoT, has the potential to change the way we interact with the devices and objects in our homes and lives.

The IoT is the idea that all of the devices and gadgets that you interact with could be connected to the internet. more>>

Non-Linux FOSS: All the Bitcoin, None of the Bloat

LinuxJournal - Tue, 2015, May26 - 10:17

I love Bitcoin. Ever since I first discovered it in 2010 and mined thousands of them, I've been hooked on the technology, the concept and even the software. (Sadly, I sold most of those thousands of Bitcoin when they were less than a dollar. I'm still kicking myself.) One of the frustrations with using Bitcoin, however, is that the blockchain has gotten so large. more>>

Dr Hjkl on the Command Line

LinuxJournal - Thu, 2015, May21 - 12:43

The first time I used vi was in a college programming course. It was the default editor on the computer lab's UNIX systems we used to compile our assignments. I remember when our professor first introduced vi and explained that you used the hjkl keys to move your cursor around instead of the arrow keys. more>>

Initializing and Managing Services in Linux: Past, Present and Future

LinuxJournal - Wed, 2015, May20 - 11:17

One of the most crucial pieces of any UNIX-like operating system is the init dæmon process. In Linux, this process is started by the kernel, and it's the first userspace process to spawn and the last one to die during shutdown. more>>

Goodbye, Pi. Hello, C.H.I.P.

LinuxJournal - Mon, 2015, May18 - 09:29
A new mini-computer is on the way, and it looks like it may be the Raspberry Pi killer we've all been waiting for (sorry Pi). C.H.I.P. is its name, and it looks set to wipe the floor with its established competitor on several counts:

1. It's completely open source. I don't just mean the software, either. more>>

Using Hiera with Puppet

LinuxJournal - Thu, 2015, May14 - 07:00

With Hiera, you can externalize your systems' configuration data and easily understand how those values are assigned to your servers. With that data separated from your Puppet code, you then can encrypt sensitive values, such as passwords and keys. more>>
