Windows 10 Junk Removal

This is a powershell script that does a number of things to remove some extra fluff from even fresh windows installs though you can also run it on existing windows installs. If you run this before ever hooking up ethernet and then reboot, you can even avoid Candy Crush etc from showing up in the first place.

I use this script regularly on all new installs but read the script and run at your own risk

Summary

_chpwd() {
    if [[ "$PWD" == */src/* || "$PWD" == */src ]]; then
        GPNEW=$(echo $PWD | sed -e 's#/src.*##')
    elif [ -d src ]; then
        GPNEW=`pwd`
    fi

    if [[ "$GPNEW" != ""  && "$GPNEW" != "$GOPATH" ]]; then
        export GOPATH="$GPNEW"
        echo "GOPATH=$GOPATH"

// This is a test where I was trying to isolate how much we lost to `reflect`
// with channel operations in a tight loop.
//
// PREAMBLE
// We do a lot of processing of stream data where ordering with respect to a
// shard indicator like user ID matters. We've done this a few times where we
// implement fanout based on hashing into an slice/array of channels, and it's
// lightning fast but it ends up leaving a lot of boilerplate in your code.
//
// So I started writing a library that would do the non-critical boilerplate

run the following:

export CONSUMER_GROUP=temp-1
export TOPICS=topic1,topic2
export ADDRS=host1:9092,host2:9092
export NUM_CONSUMERS=<number of concurrent Consumer to run>
go run multi-consumer-example.go

You'll find that when NUM_CONSUMERS > 1, things get really weird... tried with 30 initially, lowered to 2 to make the logs less spammy, same issue.
