Key-repeat suddenly stopped working in VSCode

 I had just fired up copilot and thought that was the cause.  I was editing a file in VSCode and had the Vim extension installed.  I use HJKL to move around a file, often holding down the key to move multiple lines.  It stopped working.  The K key would also pop up an Apple press and hold autocomplete suggestion that just contained a single k.

I removed the CoPilot extension and this behavior continued.  After much search, found this SO question.

This command turns off ApplePressAndHold for the VSCode application...

defaults write com.microsoft.VSCode ApplePressAndHoldEnabled -bool false

Set True to re-enable.

 Search for a filename in GitHub (all repos in an account or a single repo) with:

Mount OS/X samba share on Linux

sudo mount.cifs --verbose //192.168.1.11/scott bargamac/ -o user=scott,rw,vers=1.0

datediff bash function

Datediff function to return the number of days between two dates.  It's not too robust, but I got it working on MacOS and Linux, mostly to accommodate the differences between GNU Util date and HomeBrew BSD date...

datediff() {
    date --version >> /dev/null 2>&1
    RETVAL=$?
    if [ -e /usr/local/bin/gdate ] && [ $RETVAL -ne 0 ] ;
    then
        DATEBIN=/usr/local/bin/gdate
    else
        DATEBIN=`which date`
    fi

    d1=$($DATEBIN -d "$1" +%s)
    d2=$($DATEBIN -d "$2" +%s)
    echo $(( (d1 - d2) / 86400 )) days
}

GNU date in MacOS

The GNU date utility is provided in the HomeBrew package coreutils as gdate.  Install with HomeBrew.
