Need a tiny, $5 computer to build a robot that will bring you your slippers, initiate a massage chair session, and pour out your daily dose of bourbon?

The Onion Omega2 can do all that and more.

This tiny board is Arduino-compatible but also runs Linux natively. This means you can plug it in and get a command line or access the system via a desktop-like web interface. It has Wi-Fi built in and can be expanded to support cellular, Bluebooth, and GPS connections.

“Omega2 is a Linux computer designed for hardware projects. It does a few things. First it allows software developers to develop hardware using high-level programming languages and familiar developer tools. …”

Google Waves Goodbye to Linux for New IoT OS Fuchsia – Coming Soon to Raspberry Pi

Google has started building a new open-source operating system that doesn’t rely on the Linux kernel.

While Android and Chrome OS have Linux at their heart, Google’s new OS, dubbed Fuchsia, opts for a different kernel to create a lightweight but capable OS, suitable for running all Internet of Things devices, from embedded systems to higher-powered phones and PCs.

Instead of the Linux kernel, Google’s new OS uses Magenta, which itself is based on LittleKernel, a rival to commercial OSes for embedded systems such as FreeRTOS and ThreadX. According to Android Police, Magenta can target smartphones and PCs thanks to user-mode support and a capability-based security model not unlike Android 6.0’s permissions framework.

Data scientists have a lot of tools at their disposal, but not all of them are equally accessible. Aiming to put IBM’s Watson AI within closer reach, analytics firm Columbus Collaboratory on Thursday released a new open-source R extension called CognizeR.

R is an open-source language that’s widely used by data scientists for statistical and analytics applications. Previously, data scientists would have had to exit R to tap Watson’s capabilities, coding the calls to Watson’s APIs in another language, such as Java or Python.

As DevOps has come into its own, IT automation companies such as Chef have made automating and managing release pipelines simpler. At ChefConf 2016, Chef announced new tools which include Chef Automate, which pulls together all of Chef’s IT automation tools in one package. How DevOps teams communicate with others in their business has also changed with the rise of tools such as Slack, HipChat, and processes such as ChatOps.

In this episode of The New Stack Makers podcast embedded below, we explore how Chef Automate and ChatOps enable DevOps teams to work more efficiently, the ways in which agile development practices have shaped DevOps, and how the culture of DevOps has evolved as the ways in which businesses use software has changed. Electric Cloud Chief Technology Officer Anders Wallgren and ChatOps software provider VictorOps DevOps evangelist Jason Hand spoke with TNS consulting engineer Lee Calcote and TNS managing editor Joab Jackson at ChefConf 2016 for this podcast.

In the previous six articles in this series we learned how to manage version control on text files with Git. But what about binary files? Git has extensions for handling binary blobs such as multimedia files, so today we will learn how to manage binary assets with Git.

One thing everyone seems to agree on is Git is not great for big binary blobs. Keep in mind that a binary blob is different from a large text file; you can use Git on large text files without a problem, but Git can’t do much with an impervious binary file except treat it as one big solid black box and commit it as-is.

One of the major reasons why Linux usage has lagged behind in comparison to Windows and Mac OS X operating systems has been it’s minimal support for gaming. Before some of the powerful and exciting desktop environments came to existence on Linux, when all a user would utilize was the command line to control a Linux system, users were restricted to playing text based games which did not offer convenient features comparable to graphical games of today.

However, with the recent progressive development and immense advancement in the Linux desktop, several distributions have come into the limelight, offering users great gaming platforms with reliable GUI applications and features.

Access to TripleO QuickStart overcloud via sshuttle running on F24 WorkStation

Sshuttle may be installed on Fedora 24 via straight forward `dnf -y install sshutle` [1]. So, when F24 has been set up as WKS for TripleO QuickStart deployment to VIRTHOST , there is no need to install add-on FoxyProxy and tune it on firefox as well as connect from ansible wks to undercloud via $ ssh -F ~/.quickstart/ssh.config.ansible undercloud -D 9090

Sshuttle creates a transparent proxy server on your local machine for all IP addresses that match 10.0.0.0/24 in particular case. Any TCP session you initiate to one of the proxied IP addresses will be captured by sshuttle and sent over an ssh session to the remote copy of sshuttle, which will then regenerate the connection on that end, and funnel the data back and forth through ssh. There is no need to install sshuttle on the remote server; the remote server just needs to have python available. sshuttle will automatically upload and run its source code to the remote python.
