On the Road Again: Datalight Heads to Embedded World

The theme of this year’s Embedded World show in Nuremberg, Germany (Feb. 23-25) is “We Are the Internet of Things” and we couldn’t be more excited to demonstrate how Datalight embodies this sentiment. We will once again be co-located with our partner Logic Technology in Hall 4, Stand 108, alongside some of the most innovative software and tools purveyors in the industry.

Explaining OverlayFS – What it Does and How it Works

Union file systems are a creative solution to allow a virtual merge of multiple folders, while keeping their actual contents separate. The Overlay file system (OverlayFS) is one example of these, though it is more of a mounting mechanism than a file system. Brought into the Linux kernel mainline with version 3.18, OverlayFS allows you to overlay the contents (both files and directories) of one directory onto another. The source directories can be on different volumes and can even be different file systems, which creates an interesting mechanism for allowing temporary modification of read-only files and folders.

Security Options in Embedded Designs

A few months ago, the US Department of Health and Human Services defined a data breach as “a security incident in which sensitive, protected or confidential data is copied, transmitted, viewed, stolen or used by an individual unauthorized to do so.” Avoiding this means controlling network traffic, access to the device and applications, and protecting the data in storage.

Myth Busting: Using a Write Cache to Improve Performance Means Sacrificing Data Integrity

Perhaps the most widely held belief about write caching is that it makes a system unreliable. Something along the lines of "Data written to a cache instead of to the media will be lost on an unexpected power interruption, leaving the system in a damaged state and rendering data useless." There are a variety of options busting this myth.

File Systems Big and Small

The embedded systems market is extraordinarily diverse. Virtually any electronic device that is not a desktop computer or an enterprise data center behemoth is under the “embedded system” umbrella. With such variation in form factor, use case, price point and processing need it should come as no surprise that data storage needs differ as well.

Root Cause Analysis: The Quest for Zero Defects

Today automotive OEMs—and by extension, their suppliers—are being held to a standard that demands absolute answers whenever a component or system fails. The safeguards built in and care taken in developing these systems is high and failures are a rare occurrence, only small fractions of a percentage.

IoT Dev Conference

At last week's Internet of Things Developers Conference held in San Jose demonstrating the value of IoT was clearly top-of-mind. There were predictions of the number of devices that would be part of the IoT ranging from 20 billion to 50 billion.

Reliance Edge - the Firsts

Datalight has just released an open source preview of Reliance Edge™: our new file system for decision-quality data at the edge of Internet of Things (IoT). Later this month we will release a version under a commercial license with full MISRA C:2012 compliance. I'm excited about all the firsts with Reliance Edge, some market firsts, and some Datalight firsts.
