Netcat is like a swiss army knife for geeks. It can be used for just about anything involving TCP or UDP. One of its most practical uses is to transfer files. Non *nix people usually don't have SSH setup, and it is much faster to transfer stuff with netcat then setup SSH. netcat is just a single executable, and works across all platforms (Windows,Mac OS X, Linux).

Destination

On the receiving (destination) terminal, run:

nc -l -p 1234 > out.file

HLS streaming from node

Provided that you already have a file or stream segmenter generating your .m3u8 playlist and .ts segment files (such as the ffmpeg 'hls' muxer), this little node server will serve up those files to an HLS compatible client (e.g. Safari). If you're using node for your streaming app already, this obviates the need to serve the HLS stream from a separate web server.

// loosely based on https://gist.github.com/bnerd/2011232
// requires node.js >= v0.10.0
// assumes that HLS segmenter filename base is 'out'
// and that the HLS playlist and .ts files are in the current directory

Getting GCP access token from a service account key

Use your service account's key JSON file to get an access token to call Google APIs.

Good for seeing how things work, including the creation of JWT token.

To create a JWT token, you can replace create-jwt-token.sh script with tools like step.

If you just want to get an access token for a service account,

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
