Using TypeScript Node.js with native ESM

This reference guide shows how to configure a TypeScript Node.js project to work and compile to to native ESM.

Rationale

CommonJS module system was introduced by the Node.js developers due to the lack of the notion of "modules" in the original JavaScript (ECMAScript) language specification at that time. However, nowadays, ECMAScript has a standard module system called ESM — ECMAScript Modules, which is a part of the accepted standard. This way CommonJS could be considered vendor-specific and obsolete/legacy. Hopefully, TypeScript ecosystem now supports the "new" standard.

So the key benefits are:

• /data/certbot/www

• Nginx server in docker container

Transcoding MPEG2 TS to H.264 MP4

The goal is to transcode a DVR recording containing one video source in mpeg2 format, any number (typically 2-3) of audio sources in ac-3 format and maybe a subtitle source all together in a transport stream container. In addition the video stream might be interlaced.

The target is a video file playable natively on modern iOS and Android devices using their platforms native and hardware supported playback capabilities.

Target file container and formats

The target file container and supported stream formats are listed below to ensure very good playback compatibility on modern devices and platforms.

• MP4/M4V container format

How to automatically start ssh server on boot on Windows Subsystem for Linux

Microsoft partnered with Canonical to create Bash on Ubuntu on Windows, running through a technology called the Windows Subsystem for Linux. Below are instructions on how to set up the ssh server to run automatically at boot.

1. Edit the /etc/ssh/sshd_config file by running the command sudo vi /etc/ssh/sshd_config and do the following
   1. Change Port to 2222 (or any other port above 1000)
   2. Change PasswordAuthentication to yes. This can be changed back to no if ssh keys are setup.
2. Restart the ssh server:
   • sudo service ssh --full-restart
3. With this setup, the ssh server must be turned on every time you run Bash on Ubuntu on Windows, as by default it is off. Use this command to turn it on:

Quickly check for supported NVENC and NPP hardware acceleration capabilities in FFmpeg on your platform:

Depending on how you built ffmpeg, you may want to check the supported NVENC-based hardware acceleration capabilities in ffmpeg by running:

$ for i in encoders decoders filters; do
    echo $i:; ffmpeg -hide_banner -${i} | egrep -i "npp|cuvid|nvenc|cuda|nvdec"
done

Sample output (as on my testbed):

# this original one uses values returned from 'brew info'
brew list --formula | xargs -n1 -P8 -I {} \
    sh -c "brew info {} | egrep '[0-9]* files, ' | sed 's/^.*[0-9]* files, \(.*\)).*$/{} \1/'" | \
    sort -h -r -k2 - | column -t

# faster alternative using 'du'
du -sch $(brew --cellar)/*/* | sed "s|$(brew --cellar)/\([^/]*\)/.*|\1|" | sort -k1h
