Aetina’s “ACE-N261” Nano-ITX carrier for the Jetson TX1/TX2 COMs offers GbE, HDMI, 2x USB 3.0, 2x CAN, 2x mini-PCIe, and optional -20 to 70°C support. In April, Aetina announced a Nano-ITX ACE-N620 carrier board for Nvidia’s Jetson TX2 COM, as well as its earlier, pin-compatible Jetson TX1. The company has now announced a more feature-rich ACE-N261 Nano-ITX (120 x 120mm) carrier aimed at machine vision.

When we talk about open source hardware, we often think about the Raspberry Pi and other community-backed single board computers running Linux. Yet all these communities were modeled on the success of the 14-year-old Arduino project, in which Linux has been only tangentially involved, and only over the past four years.

Digital typography is something that we use every day, but few of us understand how digital fonts work. This article gives a basic, quick, dirty, oversimplified (but hopefully useful) tour of OpenType— what it is and how you can use its powers with free, libre, and open source software (FLOSS). All the fonts mentioned here are FLOSS, too. read more

When you know a software developer's preferred operating system, you can often guess what programming language(s) they use. If they use Windows, the language list includes C#, JavaScript, and TypeScript. A few legacy devs may be using Visual Basic, and the bleeding-edge coders are dabbling in F#. Even though you can use Windows to develop in just about any language, most stick with the usuals. read more

Microsoft has recently increased their stakes in the Kubernetes community through a variety of actions. For example, they acquired Deis, a company that specialises in Kubernetes container management technologies. And, Microsoft became a member of the Cloud Native Computing Foundation, which is the home of the Kubernetes project.

Version 4.1.4 did fix four security vulnerabilities, and that's one less than the five that appear to be outstanding for the software, based on two reported in the November 2016 minutes of Apache Foundation Board of Directors' meeting and three reported in the April 2017 minutes.

Looking at the open organization principles (transparency, inclusivity, adaptability, collaboration, community) and the reasons we practice them (building a network of people dedicated to a purpose and sharing the same ethical standards, for example), I started wondering how these principles would be influenced by an increasingly important emerging technology: blockchain. read more

I've covered scientific software in previous articles that either analyzes image information or actually generates image data for further analysis. In this article, I introduce a tool that you can use to analyze images generated as part of medical diagnostic work.

Gnocchi is an open source time series database created in 2014 when OpenStack was looking for a highly scalable, fault-tolerant time series database that did not depend on a specialized database (e.g., Hadoop, Cassandra, etc.). read more

This article is about high availability or disaster recovery and fail-over for Linux on Power virtual machines (VMs) or logical partitions (LPARs). The solution described in this article works for all Linux distributions available for IBM POWER8 and later processor-based servers. Open source software used in this solution are: DRBD and heartbeat, which are available for all supported distributions. We have used Ubuntu v16.04, supported on IBM Power servers to explain and verify the solution.

Do you use "open source software" or "free software"? Although there are different rules for free software licenses (four freedoms) and open source licenses (Open Source Definition), what is not apparent from those two sets of rules is: read more

Buried deep inside your computer's Intel chip is the MINIX operating system and a software stack, which includes networking and a web server. It's slow, hard to get at, and insecure as insecure can be.
