  1. Having clocks synchronized between your servers is extremely useful. For example, having a guarantee that the timestamp of arrival of a packet (measured by the clock on the destination) is ALWAYS bigger than the timestamp recorded by the sender is a huge win, especially for things like database scaling.

    For this though you need to go beyond NTP into PTP which is still usually based on GPS time and atomic clocks

  2. Getting from 95% compatible to 100% compatible may not only take a lot of time, but also result in worsening the performance. Sometimes it's good to drop some off the less frequently used features in order to make the tool better (or allow for making the tool better)
  3. 1. The prepaid Visa or Mastercard come with an extra fee (like 5-6 dollars per card if I recall correctly?)

    2. I didn't see the prepaid cards in stores outside the US, so they are probably not that popular outside.

    Sometimes you also want to shift your spending, like if you spend 500 USD this month at this store, you'll get some good % cashback. So you end up buying a gift card that you know you'll definitely use next month.

    I think this is irrelevant, TBH.

  4. But gift cards aren't supposed to work that, right? If it wasn't "legal" or "okay" to have a 500 dollar card, they shouldn't be sold. They are available, therefore they should be perfectly usable.

    I don't want to speculate more, but one of the use cases for them is for people that choose to not use cards online (or even don't have credit cards at all) to be able to buy digital goods with cash.

    Either way, if we're questioning buying/using the gift card, we're blaming the victim

  5. These devices usually have detachable antennas, so just unscrew them
  6. > I'm more curious how/why the author ended up with a $500 gift card. That's a large amount, and the author never shares how this was obtained, which seems like a key missing detail. Did the author buy the gift card for himself (why?) or did someone give him a very large gift (why not mention that?)

    The author mentions a big store (names it similar to Walmart for US based readers).

    I would assume this was an accepted form of "return a product without a receipt" or "we want to accept your complain about this product we sold going crazy 1 day after it's warranty but we cannot give you cash back" etc

  7. The file operations on macOS are rather slow too. I needed to invest in some rsync-based syncing for an in-docker application build as accessing the mounted volume from a Docker container was around 20 times slower than on Linux :O
  8. at this point you don't need the phone :D
  9. With lack of regulations, the theory is, there will be many competing manufacturers of insulin, dropping the cost down. Probably not as simple as that, but that's the idea at least
  10. I think yes. And that's maybe the reason they didn't properly split the files to .cache/ .config etc
  11. There's an extension for that. Quite handy for in-browser terminals like one in AWS etc.

  12. I must have missed the video apparently...
  13. My understanding of this technology is that it's closed-circuit. No water is exchanged between the power plant and the ocean once filled with ocean water.
  14. I like Docker(compose) + Portainer for small deployments
  15. pCloud also has lifetime payment for a storage service.

    This must be some kind of Ponzi scheme, I guess they must count on

    1. storage getting cheaper 2. traffic getting cheaper 3. that people will need more and more storage with time

  16. > Can “second life” EV batteries work as grid-scale energy storage?

    Yes.

    Thank you

  17. My guess would be that the manufacturer didn't remotely block the device, but rather the device itself did.

    If last connection time < N days ago and last M tries connecting were unsuccessful, then: brick myself.

    Still shitty, no doubt (and very similar to planned obsolescence), but the customer can un-brick by resetting to factory like they did in the service center.

  18. don't you just love how many ways of going full screen there are in macOS
  19. Found first (!) thing that I cannot justify: sleep(number) sleeps for number of MILLISECONDS rather than - more naturally - seconds. The only possible explanation I found is that this maybe accepts a int rather than a float. (In this case the function should be called sleep_ms, not unlike unix_ms)
