As with many things I post here, this article was the result of a problem I encountered, and how to resolve or work around it. I have been working with Docker on Windows and was attempting to run a container provided by Microsoft that included SQL Server. The process is fairly easy, just pull the image and run it with the appropriate command options. Unfortunately, that didn’t work. When I used the supplied command to run the container, I would get this error message:
Error response from daemon: failed to create endpoint <container name> on network nat: HNS failed with error. Unspecified error.
I spent several hours working this out over the past few days, doing web searches and trying various ideas. Lots of people experiencing the problem, but no solutions. Eventually I figured out a solution. Hopefully this helps someone else. The error above I found out indicates a problem with the default ‘nat’ network that Docker creates when you install it. By using the default NAT network, you basically have a private network on your docker host.
You can attempt to delete that network by opening PowerShell as Administrator. (Microsoft has a good write-up on networking for Windows containers here.) Enter the following command to see a list of the virtual networks defined on your PC:
Stop Docker using the whale icon on your notification area, by right clicking on the whale and choosing Quit Docker from the menu. Then run this command:
Enter “Y” at the prompt to remove all networks. Now restart Docker. If this doesn’t work for you, read on.

After downloading Talend Open Studio Data Integration this week, I ran into a similar issue to one I’ve experienced before while using Pentaho Data Integration. I extracted the TOS zip file to a folder under Applications and attempted to start the TOS_DI_macosx_cocoa application. I got an error message that Talend couldn’t access its resource library, and it shut down.
Since Talend DI runs on JAVA, I thought the issue might lie with the quarantine process in OS X Sierra, that has been “improved”. Well I was right! Keep reading to see how to get TOS to run on your Mac!

A new version of Mac OSX and a new version of Pentaho Data Integration (aka Kettle) but the same old problem getting Kettle to run. Apple tries to keep their operating system locked down and secure, so if you download applications from the Internet that aren’t from the Apple App Store, the files are quarantined.
With the update to Sierra, the quarantine process has been “improved”. Keep reading to see how to do it!

This is my second article on using Microsoft’s new Linux version of SQL Server with R. This time, I’ll cover how to use RODBC to gather data from SQL Server. As a bit of background, over the past few months, I have been working to learn R, a free software environment for statistical computing. Its been gaining popularity over the past few years, and Microsoft just gave it a huge boost by integrating R into their Power BI visualization software and in the Windows version of SQL Server 2016. Since a good deal of my work involves connecting to Microsoft SQL Servers its a good opportunity to show how to connect to a SQL Server installed on Ubuntu from R using ODBC.
For this tutorial, I am going to assume that you already have R installed. For my purposes, I am running R on the same Ubuntu machine as the SQL Server. If you need instructions for installing SQL Server on Linux, Microsoft has provided a write-up already. So now let’s get started.
