  • Am I going to be behind the competition by doing this?

    Yes, because you are due a lot more diligence with open source, and that will slow down your releases.

    If the most secure crypto algorithms are the ones that are public, can we ensure the security of a bank’s apps by publicizing it?

    You trade security by obscurity for security by expert oversight. I’m not a lawyer or baking auditor, but I’d say while zero-days are problematic for open source software projects; they can be life-ending for banks.

    Is there a technical reason they don’t publicize their code or is it just purely corporate greed and nothing else?

    This is a false dichotomy. Financial reasons to not publicize the code are technical reasons. Finance is technical.


  • H-h-how? HOW? do they ‘anonymize’ DNA?!?!

    If you really curious, it is possible depending on the sections of the DNA being shared and how aggregated they are. Not saying that this will be the case - it’s quite likely that this sale would be done prioritizing value instead of privacy - but it is possible. The key part is to not treat the whole DNA as a data sample, but specific sequence sections, as isolated as possible.

    And the Netflix example is instructive but not super relevant here. If you already have your SNPs in a public database out there, then yeah 23andMe might not be able to effectively anonymize your samples; but you don’t (I hope).




  • You did say earlier that you cook once a day, meal for two. When I do that, all dishes for the day take a third of the maximum load on my machine, so I could wash once every three days, therefore averaging like 3 L per day tops? You handwashing every day are spending 6-8L daily which is more than double.

    If it is true that you can spend <8L for an arbitrarily large amount of dishes, though, then I guess there must be an amount of dishes that you will outperform a dishwasher. They cannot handle an infinite amount of dirt, unfortunately. If you hand wash every 7 days you will be averaging less than 1L a day which really does sound unbeatable.



  • It’s plausible that handwashing uses less electricity, specially if you let the machine heat-dry the dishes. But water? If you do the comparison against a fully-loaded machine, no way. Modern machines use half the water from machines of 15 years ago, and those were already competitive against handwashing. Best case scenario for handwashing (single water bath) still uses about twice as much water. Dishwasher detergent is stronger and the machine takes longer so it has more contact time, the chemistry heavily favours using less water for the same amount of gunk to dissolve.

    In your case, as you already mentioned you only cook once a day and you don’t want to degrade your high end stuff in the machine, it’s reasonable that you won’t generate dishes enough to fill the machine. If you would be using a half-loaded dishwasher then it is plausible that you would use less water handwashing, but it’s still a close call - which is why I sometimes use the machine filled 1/3 without worry.



  • If it’s worth to purchase a dishwasher… it varies a lot given each ones own priorities and situation.

    If saving X minutes a day is a big thing or a small thing… it also varies a lot given how you value your time and how much you enjoy dishwashing by hand. I know a few people who love to do it; no need to take away that joy for the sake of efficiency.

    But for the vast majority, if you have a dishwasher idle, those are some minutes you get back practically* for free.

    I also cook only for two, but I do it three times a day, and I have a lot to do so I value each minute saved in chores immensely. My dishwasher has been a blessing, without it I would be eating out or ordering delivery MUCH more frequently.
