  • Custom SCCM Report for Product Name, by Version

    Out-of-the-box reporting in Config Manager (SCCM) can handle most reporting needs, but usability suffers when the application in question is deployed across the enterprise environment, and in various patch levels.

  • Deploying SCCM Applications to User Collections as “Available”

    Deploying SCCM Applications to User Collections as “Available”

    Earlier this week, I encountered what me and several colleagues thought was a fluke in SCCM 2012 application deployment — an “available” deployment to a user collection does not show in Software Center, whereas a “required” application deployment to a user collection will show in Software Center.

     

    Available Deployment Setting

    Turns out, the available deployment is designed to show up in Application Catalog, a feature of SCCM 2012 that my company does not use, nor have turned on.

    For the majority of deployment scenarios, we deploy App-V applications to user-based collections that query from AD security groups. If you add the target user-id to the appropriate AD security group, the corresponding SCCM user collection will then reflect the change after its scheduled query update. Most of our App-V deployments are set to required for these collections, but there are a handful that we have historically advertised as available (instead of required), allowing the user to pull the App-V application on-demand at the most convenient time. This approach worked fine with SCCM 2007, and apparently would work in SCCM 2012 — assuming we used the Application Catalog.

    This seems like an unnecessary layer of complexity that could be avoided by having both required and available deployments display in Software Center. But for now, we have to adjust our deployment strategy since we have no plans to utilize Application Catalog.

  • SILS Framework for Co-Operative Flight of Autonomous Drones

    This was an interesting project that eventually evolved into my Masters project at the University of Louisville. It was based upon previous work (sponsored by Dr. Adrian Lauf) on a system for autonomous flight of lightweight unmanned aerial vehicles (UAVs). Research and development of the system was divided into multiple components with the eventual goal of providing disaster relief teams a group/swarm of UAVs to assist in search and rescue efforts. The UAVs/drones relay back to the ground station during flight captured images and streaming video, providing critical analysis of target areas that may otherwise be inaccessible to human teams.

     

    Abstract

    A comprehensive software-based approach to the simulation of unmanned aerial vehicles (UAVs) in co-operative flight, without the need for physical hardware connections. Software in the loop (SILS) simulation allows for the development and testing of co-operative flight patterns without the risk associated with hardware-based testing. This framework incorporates simulation components from the ArduPilot autopilot module and JSBSim flight dynamics model to create a virtual flight environment.
