Recently I wanted to create an Arduino-based low-power Internet of Things (IoT) device for makers, with built-in sensors that could be used to deliver sensor data from any location to the cloud, and potentially control connected devices such as thermostats, lights, door locks, and other home automation products. Along the way, I learned that creating a new IoT device, from idea to prototype to final product, is not as simple as I thought it would be, and there was no "ready-to-go" development device to start with. read more

I grew up with console gaming and over the years I have had a number of systems, including Atari, SNES, Sega Genesis, and my all-time-favorite—the Commodore Amiga. I recently found a backup of old games I have been carrying around with me for years and got nostalgic for the glory days of retro gaming. I grabbed some old hardware and started tinkering with it so I could relive my childhood. I was surprised how well these games run on my Raspberry Pi and it's become something of a new hobby. read more

As some of you might already know, an object or executable file in Linux consists of several sections (like txt and data). In case you want to know the size of each section, there exists a command line utility - dubbed size - that provides you this information.

Fixing Meltdown and Spectre will take Linux -- and all other operating systems -- programmers a long, long time. Here's where the Linux developers are now.

I've been to a lot of tech conferences in my life, but there was something different about the December 2017 KubeCon/Cloud Native Computing Foundation (CNCF) Summit in Austin. Sure, there's a ton of hype around Kubernetes, but it's something more.

This article will cover the installation of Docker on desktop Linux, macOS, and Windows, and it is intended for beginners who want to get started with Docker containers. The only prerequisite is that you are comfortable with command-line interface.

It is, at times, important to know when things change in the Linux OS. The uses to which systems are placed often include high-priority data that must be processed as soon as it is seen. The conventional method of finding and processing new file data is to poll for it, usually with cron. This is inefficient......

Gaming has traditionally been one of Linux's weak points. That has changed somewhat in recent years thanks to Steam, GOG, and other efforts to bring commercial games to multiple operating systems, but those games often are not open source. Sure, the games can be played on an open source operating system, but that is not good enough for an open source purist. read more

It has been too long, but I was at least one of the founders of the Seattle UNIX User's Group. I remember the first meeting well. It took place at Seattle University, and our guest speaker was Bill Joy. He impressed me in that he had a huge pile of overhead transparencies (remember, this was in the 1980s), asked a few questions of the group, selected some of them and started talking.

Imagine you're about to play a board game that involves using dice, say Monopoly, Yahtzee, Cluedo, Dungeons & Dragons...1 In most cases, at least where you're interested in playing a fair game, you want to be pretty sure that there's a random distribution of the dice-roll results. In other words, for a six-sided dice, you'd hope that, for each roll, there's an equal chance that any of the numbers one through six will appear. read more
