  • These kind of “manual” a/c units normally have a little sticker or a caution in the manual to “wait 5 minutes before restarting”.

    People can easily trigger this kind of thing just by turning the thermostat back and forth, so there is usually a thermal cutout on the compressor to keep them mostly safe.

    You can usually hear it when it activates, there will be a hum from the stalled compressor for a few seconds and then a little click, and then the compressor won’t start for a minute or two.










  • They’re not missing funds though, it’s not a discrepancy in accounting. They overpaid , they know where the money is, and it’s simply a business decision whether to recover it or not.

    They could have simply filtered on overpayment above some arbitrary value based around recovery vs goodwill.

    Or they could have let it slide, but still notify people so that they wouldn’t be wondering if it was an accounting error.

    But no, they want to recover 23 cents which is well below the cost of everyone’s time and effort to deal with, on both sides of the transaction.





  • Why the fuck isn’t there just a simple status LED that is on the same circuit as the camera?

    Because cameras aren’t simple on-off devices powered by a single wire, that’s why. It’s always got power, and it’s turned “on” (send image data over the data bus) and “off” (do not send data) by software commands over the same data bus.

    So the most convenient solution is then have the camera IC have an output that can drive an indicator light. And as camera ICs are basically full computers in their own right, they can be reprogrammed so that they don’t turn on that output.

    End result is that you are much better off either having a physical cover over the camera lens, or having a USB camera that you can unplug.





  • I don’t think there’s anything commercially available that can do it.

    However, as an experiment, you could:

    • Get a group of photos from a burst shot
    • Encode them as individual frames using a modern video codec using, eg VLC.
    • See what kind of file size you get with the resulting video output.
    • See what artifacts are introduced when you play with encoder settings.

    You could probably/eventually script this kind of operation if you have software that can automatically identify and group images.



  • Letting it ring has no impact. They have autodiallers that call, and when someone picks up, only then is that call assigned to someone in the call centre.

    You can often tell this because there is a marked delay in the response to your initial “Hello?”. Long enough that you can reliably just hang up if you don’t hear a response in two seconds.

    If it’s a real person who actually wants to call you and they you call again straight away, you can just shrug off your hang-up as a network issue.
