PostgreSQL cheat sheet for MySQL users
View psql.md

I use PostgreSQL via the psql client. If you use a different client (eg. pgAdmin, etc.), I don't know how much will translate over.

One nice difference between psql and mysql (cli) is that if you press CTRL+C, it won't exit the client.

Remove noise from video using sox and ffmpeg
View denoise.sh
# 1. extract audio from all videos (assuming .mp4 videos).
for FILE in *.mp4; do ffmpeg -i $FILE ${FILE%%.mp4}.wav; done
# 2. use the first second of the first audio file as the noise sample.
sox `ls *.wav | head -1` -n trim 0 1 noiseprof noise.prof
# Replace with a specific noise sample file if the first second doesn't work for you:
# sox noise.wav -n noiseprof noise.prof
# 3. clean the audio with noise reduction and normalise filters.
