Not to say I agree with that comment. But I think the case for why ECC would be easier to break than RSA using quantum computing is that key sizes of ECC are much smaller so would require less qbits to break.
This gets close but I don’t think it will then allow you to easily see which of these periodic tasks you can work when you have a few hours to spare today.
Can U suggest a feature that I’ve been looking for in a TODO app for a long time. Tasks that are periodic but not urgent. Like changing the filters on your heating system every 6 months, adding fertilizer to the garden every 3 months, etc. Then when you have some time to spare you can easily see these kinds of tasks that you normally forget.
