Without Spanning Tree Protocol (STP) or Rapid STP (RSTP), a LAN with redundant links would cause Ethernet frames to loop for an indefinite period of time. With STP or RSTP enabled, some switches to block ports so that these ports do not forward frames. STP and RSTP intelligently choose. In 2001, the IEEE introduced Rapid RSTP as 802.1w RSTP provides significantly faster recovery in response to network changes or failures, introducing new convergence behaviors and bridge port roles to do this. Please note RSTP was designed to be backwards-compatible with standard STP, link below with more information about these to protocols.

I want to share this information on Azure Extensions for Visual Studio Code. The extension allows you to use Azure directly from Visual Studio Code. This can be done by using either the Azure CLI or the Azure App Service extension, you can have your application running in Azure in minutes, link below to a website with more information.

Information on performance profiling with Visual Studio Code.  Talking about how to resolve performance issues in your application after shipping it, by using the profiling tools in Visual Studio. This is a multi-part series with profiler PMs Esteban Herrera and Sagar Shetty, they explore the world of profiling and the tools that can improve your code's performance. In part 2 of our multi-part series on performance profiling, they explore the different profiling tools in Visual Studio and when each tool can be used. Example the items they review is Performance Profiler tool, the Diagnostics Hub tool and the Profiling Optimization. I

In part 3 of the multi-part series on performance profiling,  shows us how to profile apps once they are in production. Link below to all three of the video's that make up this series.

Topic for this post will be JSON Web Token. JSON Web Token is an open standard, under RFC 7519, that is defines a compact and self-contained way for securely transmitting information between parties as a JSON object. JSON Web Token is an internet standard for creating data with optional signature and/or optional encryption whose payload holds JSON that asserts some number of claims. This information can be verified and trusted because it is digitally signed. The tokens are signed either using public or a private key. Below are links, with information how to work with JSON Web Token, for a Drupal website.

First link is to a blog by “Media Current” website, titled “Using JSON Web Tokens (JWT) to Authenticate Requests to REST Resources in Drupal 8.” It go's through the steps of setting up JSON Web Token on a Drupal 8 website, to authenticate some core REST resources. Second link is a video from DrupalCamp NJ YouTube page, presentation on working with JSON Web Token, I was present, at the online record of this video. The third links is the Drupal main website, with information on the Drupal module for JSON Web Token Authentication (JWT).
