as written in [MDN][1] at July 2016: This feature is not implemented in any browsers natively at this time. It is implemented in many transpilers, such as the Traceur Compiler, Babel or Rollup. So here is example with Typescript loader for Webpack: //TODO Create simplified version of this ar...

Do not use registry:latest! This image points to the old v1 registry. That Python project is no longer being developed. The new v2 registry is written in Go and is actively maintained. When people refer to a "private registry" they are referring to the v2 registry, not the v1 registry! do...

Configuring a private registry to use an AWS S3 backend is easy. The registry can do this automatically with the right configuration. Here is an example of what should be in your config.yml file: storage: s3: accesskey: AKAAAAAACCCCCCCBBBDA secretkey: rn9rjnNuX44iK+26qpM4cDEo...

IISNode allows Node.js Web Apps to be hosted on IIS 7/8 just like a .NET application would. Of course, you can self host your node.exe process on Windows but why do that when you can just run your app in IIS. IISNode will handle scaling over multiple cores, process manageement of node.exe, and auto...

To get this example working, you'll need to create an IIS 7/8 app on your IIS host and add the directory containing the Node.js Web App as the Physical Directory. Ensure that your Application/Application Pool Identity can access the Node.js install. This example uses the Node.js 64-bit installation....

Simulation environments A simulation environment for a VHDL design (the Design Under Test or DUT) is another VHDL design that, at a minimum: Declares signals corresponding to the input and output ports of the DUT. Instantiates the DUT and connects its ports to the declared signals. Instant...

This example deals with one of the most fundamental aspects of the VHDL language: the simulation semantics. It is intended for VHDL beginners and presents a simplified view where many details have been omitted (postponed processes, VHDL Procedural Interface, shared variables...) Readers interest...
