  • The issue with cloud providers like AWS is that they charge for virtually everything, and that makes it easy to rack up charges if you forget about something you spun up as a test last week and forgot to terminate it. For larger companies it can be a significant issue. So there are other companies out there that you can use to scan your entire AWS account, summarize what you’re using, and highlight things you may not need any more. They’ll also recommend cost savings measures like paying for a year of server time up front instead of paying as you go. If you know you’ll need a server for a year then paying annually is a lot less expensive.

    On the plus side, you don’t need to deal with things like hardware failures. We have a large AWS environment where I work, and we’ll occasionally get an email informing us that an instance is “running on degraded hardware”. A simple reboot (power cycle) will move the instance to new hardware. And if you decide you need more RAM, more CPUs etc. then it’s also as simple as rebooting.




  • The article doesn’t make it clear (it could be better written) but my guess is that the card was actually found intact in the wreckage that they recovered back when the sub went down.

    The various documentaries by Netflix, Nat Geo, etc. only came out a few months ago as the USCG investigation wrapped up. Those revealed new details, like that they had recovered personal belongings from the pockets of one or two of the victims. I don’t think those details were publicly known (or at least reported on) until the documentaries came out. This is likely just a similar case of more evidence coming to light.



  • Biometrics are not usernames. They are physical identifiers and unlike usernames you can’t change them.

    I used to work in a datacenter that required you to go through a mantrap to access. It required three things:

    1. Something you have (a card key)
    2. Something you know (a PIN)
    3. Something you are (biometrics)

    To get to the datacenter floor you use a card key to open the door to the mantrap. It’s a small vestibule about the size of a phone booth. Once inside the door closes. You then enter your PIN on a keypad and place your hand on a biometric scanner. Once your hand is recognized the inner door opens and lets you into the datacenter. I was told the mantrap also weighed you and compared that with previous trips through to make sure somebody else didn’t sneak through with you.







  • Even home battery solutions. We have solar panels & a Powerwall. Were part of a Virtual Power Plant along with around 1500 other Powerwall owners in the region. During peak usage in the summer all our PowerWalls feed back to the grid so that our utility provider doesn’t have to spin up expensive (and dirty) peaker plants. We get paid a premium for the power we provide during these events.

    I saw articles here on Lemmy just a month or two ago that Tesla successfully tested a VPP in California that consisted of 100,000 PowerWalls.


  • Which is a rather bizarre claim to make. I travelled to NZ and Australia about 20 years ago. When I went through NZ customs they wanted to see proof of where I was staying and more importantly that I had airline reservations to leave NZ. So they wanted proof I was just visiting and planned to leave in a timely manner.

    When I went to Australia the customs officer just stamped my passport and let me through, no questions asked.

    Why deal with the hassle of NZ as a stepping stone if I could just go straight to Australia and avoid that hassle?
