Backing up Spotify 7 months ago

For reference, considering you can purchase a 12-month Spotify Premium subscription via a $99 gift card at the moment, that same $6k could be used for 60 years of Spotify Premium.

I have a single night of sleep logged to Apple Health in the last 6-months, and the 6 month average exactly matches that single night. It seems that the author of this app is assuming that Apple is using the wrong denominator when calculating the 6-month average, but I think there could be other explanations for the difference in calculated values. For example how the two approaches might deal with data from different sleep data sources within Apple Health from the same date, how multiple sleep sessions on the same calendar date are merged prior to averaging, etc.

Also keep in mind that the Daylight doesn't have an e-ink screen like a Kindle. It is instead a grayscale transflective LCD. That is why it is able to have a high refresh rate like other LCD panels.

Yes, FEMA is federal. If eliminating FEMA lowers federal taxes states could increase their state taxes to compensate and each have their own emergency management agencies. But generally it seems like having 50+ emergency management agencies is less efficient than having 1.

Typically eye-trackers work by illuminating the eyes with near infrared light and using infrared cameras. This creates a higher contrast image of the pupils, etc. I assume Apple is doing this in the Vision Pro. Eye-tracking can also be done with just visible light, though. Apple has the benefit of knowing where all the user interface elements are on screen, so eye-tracking in this on the iPhone or iPad doesn't need to be high precision. Knowledge of the position of the items can help to reduce the uncertainty of what is being fixated on.

Their pocket operator series were inexpensive, at $60-100 per model, but were very basic with essentially a bare PCB and most of the electronics protected by being placed under the screen. I believe that much of the cost of their expensive products is due to a lot of custom parts like CNC machined aluminum enclosures. This product seems designed to hit a price point between the pocket operators (~$100) and their plastic OP-Z (~$500).
