# Save this script to /bin in order to generate RAW photo thumbnails in Ubuntu
# Save raw.thumbnailer to /usr/share/thumbnailers
# Note: you cannot put the script to e.g. /home, as thumnailers are now run in a sandbox provided by bwrap
# Requires exiftool and imagemagick (note: use real binary name of convert instead of /etc/alternatives, because it's not accessible from bwrap)

// If you want to use Mongoose with TypeScript, you are in trouble.
// Typegoose comes to the rescue, but it requires model classes to extend Typegoose class,
// which breaks using model classes as interfaces for casting in your code

// Here is the solution: don't extend Typegoose and use this function to create your models:

import {InstanceType, Typegoose} from 'typegoose'
import {Connection, Model} from 'mongoose'

function buildModel<T, U>(constructor: {new (): T} & U, db: Connection, collectionName: string): Model<InstanceType<T>> & U {

# This may be a useful trick with other executables as well that can only write to syslog
