An Introduction to Linux Filesystems

This article is intended to be a very high-level discussion of Linux filesystem concepts. It is not intended to be a low-level description of how a particular filesystem type, such as EXT4, works, nor is it intended to be a tutorial of filesystem commands. Every general-purpose computer needs to...

How to Check Bad Sectors or Bad Blocks on Hard Disk in Linux

Let us start by defining a bad sector/block, it’s a section on a disk drive or flash memory that can not be read from or written to anymore, as a result of a fixed physical damage on the disk surface or failed flash memory transistors. As bad sectors continue to accumulate, they can undesirably or...

Despite some challenges, the smart home segment appears to be rebounding with the help of maturing technology and IoT interoperability standards. Mycroft (pictured here) offers an Echo-like hub that runs Snappy Ubuntu Core on a Raspberry Pi.

Smart Linux Home Hubs Mix IoT with AI

Industrial, rather than home, applications will likely dominate the Internet of Things (IoT) market in the years to come. Yet, in the early going, the home automation market has had the greatest visibility. And it hasn’t always been pretty. Despite steady growth, retail sales have yet to achieve...

Two Arduinos Become One

The schism between two Arduino companies (that we covered in March 2015) has apparently been settled. The poster child for the open hardware movement is now under one company "Arduino Holding" and a new not-for-profit Arduino Foundation has been started. "Massimo Banzi, Co-Founder of Arduino LLC,...

ROS is an open source framework for creating advanced robots; it sits on top of an existing OS such as GNU/Linux.

ROS: An Open Source Robotics Platform on Linux

ROS is an open source framework allowing you to create advanced robots. Using ROS takes much of the tedious work out of creating useful robots because it supplies code for navigation, arm manipulation, and other common robot tasks. ROS allows various software components to communicate between one...

What’s the Difference Between Consumer and Industrial IoT?

The Internet of Things is invading everything from consumer to industrial products, but all platforms are not created equal. The Internet of Things (IoT) is the latest product-development buzzword, akin to other terms like “the cloud” or “smart cities.” These terms are typically very nebulous, but...

IoT boards
Intel's IoT-oriented Intel Joule module runs on the latest, 14nm “Broxton-M” Atom SoCs and is supported by the Yocto Project-based Ostro Linux.

Linux and Open Source Hardware for IoT

Most of the 21 open source software projects for IoT that we examined last week listed Linux hacker boards as their prime development platforms. This week, we’ll look at open source and developer-friendly Linux hardware for building Internet of Things devices, from simple microcontroller-based...

Security of the boot chain is a vital component of any other security solution, said Matthew Garrett of CoreOS in his presentation at Linux Security Summit.

Matthew Garrett Explains How to Increase Security at Boot Time

Security of the boot chain is a vital component of any other security solution, said Matthew Garrett of CoreOS in his presentation at Linux Security Summit. If someone is able to tamper with your boot chain then any other security functionality can be subverted. And, if someone can interfere with...
