function get_stack() {
    local STACK=""
    local i message="${1:-""}"
    local stack_size=${#FUNCNAME[@]}

    # to avoid noise we start with 1 to skip the get_stack function
    for (( i=1; i<stack_size; i++ )); do
        local func="${FUNCNAME[$i]}"
        local linen="${BASH_LINENO[$(( i - 1 ))]}"

Enable LDAP over SSL (LDAPS) for Microsoft Active Directory servers

By default Microsoft active directory servers will offer LDAP connections over unencrypted connections (boo!).

The steps below will create a new self signed certificate appropriate for use with and thus enabling LDAPS for an AD server. Of course the "self-signed" portion of this guide can be swapped out with a real vendor purchased certificate if required.

Steps have been tested successfully with Windows Server 2012R2, but should work with Windows Server 2008 without modification. Requires a working OpenSSL install (ideally Linux/OSX) and (obviously) a Windows Active Directory server.

• Create root certificate
• Import root certificate into trusted store of domain controller
• Create client certificate

Did you ever had to debug some large cell in a Jupyter notebook? In the below I share my experience on the subject. We'll review the classical methods for debugging notebooks, and finally I'll show how to set breakpoints in PyCharm for code being execute in a jupyter notebook, and benefit of the comfort of a real Python IDE for debugging.

Debug in the notebook

Before I actually describe what Pycharm can do, we quickly review the jupyter commands for debugging.

"""
This is a script designed to be "safe" drop-in replacements for the
shutil move() and copyfile() functions.

These functions are safe because they should never overwrite an
existing file. In particular, if you try to move/copy to dst and
there's already a file at dst, these functions will attempt to copy to
a slightly different (but free) filename, to avoid accidental data loss.
