PowerShell Import-Module with .ps1 quirk

Well, not so much a quirk - but an interesting anti-pattern I found in some (poor quality) PowerShell. Documenting the "how and why" so I can refer to it again if needed!

Kodi media player - update video database file paths

• The Kodi databases are all SQLite3 based.
• For Linux, the video database will be located at: ~/.kodi/userdata/Database/MyVideosXX.db, where XX is the version number. You will most likely want the highest number available for edit.

Install SQLite CLI tools, open database

$ sudo apt-get install libsqlite3-dev sqlite3
$ sqlite3 MyVideosXX.db

SSL certificate - compare certificate vs. private key

Or to put it another way...

Does this certificate I have actually work with this private key I have?

Where server.crt is your certificate and server.key is your private key:

$ certMod=$(openssl x509 -text -noout -modulus -in server.crt | grep "Modulus=") && \
	keyMod=$(openssl rsa -text -noout -modulus -in server.key | grep "Modulus=") && \
	[[ $certMod == $keyMod ]] && echo "Equal"

Compile ssh2 bindings extension for PHP7

The current PHP ssh2 extension via PECL won't compile under PHP7.

Using a more recent version via PHP's GitHub we can make this work.

$ sudo apt-get install autoconf libssh2-1-dev
$ curl -LO https://github.com/php/pecl-networking-ssh2/archive/master.zip
$ unzip master.zip
$ cd pecl-networking-ssh2-master
