@AlbertRetey thank you, that is something I didn't consider! I will definitely do that.

comment Deleting a line from a file
Perhaps backup is a bad choice of words. I'm running a script on a cluster and it may be terminated so I want to periodically output the current state so that I can restart it from there. However I have a storage quota and each update is quite large so want to overwrite the previous update.

Thanks for your response! However, this doesn't overwrite the previous content.

comment How to reduce a quartic form to a quadratic form with equal roots
@halirutan sorry, I should have made that clear. It only needs to be positive when the variables have 0/1 values.

comment How to reduce a quartic form to a quadratic form with equal roots
@halirutan sorry that was a typo. It was meant to be (xy-zw-1)^2. The positivity is the main challenge of the question. I have cross posted the question on the maths stackexchange.
