Well, this does the actual measurement. Measurement is how deviations from theory are discovered.

Please define 'real'.

Single shot from single place instead scanning it for ALL DAY and claiming it's real time etc haha

This is an improvement on a older technique: https://www.reddit.com/r/educationalgifs/comments/6wqwh1/lig...

or see https://en.wikipedia.org/wiki/Femto-photography

Also a technique used all over the place for studying how molecules react to light. Probe it with as short of a laser pulse you can afford to buy and measure the light emitted by it some time later. My wife has been doing this basic technique for years studying things like molecules to generate fuels from sunlight. (Or was until solar energy funding as practically eliminated last year, now it's studying other things using similar techniques)

I am not a compass-nerd at all, and wonder: why don't we all use electronic compasses these days? Or, why use compasses at all? easier ways of navigating have been developed.

Multiple reasons:

1. A traditional compass is cheaper. They are so cheap they are built into the caps of ultra-cheap hiking sticks.

2. Traditional compasses don't need recharging.

3. Traditional compasses don't seem to be as easily fooled by stray EM noise. It could be the inertial dampening of the mass of the needle, but I've been in the woods where expensive electronic compasses misfired, but the old-fashioned one still worked just fine.

4. Dedicated devices have far lower usage hurdles. If I'm hiking, a glance at the top of my stick tells me the general (8-point) direction I'm going. An electronic compass at a minimum requires me to fish out a device and turn it on, or open an app.

5. If you aren't navigating by precise map measurements, all you really need is 8-point information (that is, "northwest" instead of 281 degrees). Needles in a circle are perfect for this; digital degrees are not.

The reasons listed already, plus many events that involve navigation (like fell running) specifically ban electronic equipment.

We do use electronic compass. That’s how google maps on your phone knows which way you are pointing.

Untrue. Google maps infers direction from multiple time-separated locations - that is, your velocity vector. If you don't move, it guesses - and is quite often wrong.

No. You can see blue emit from your position in the direction your phone is pointing. If you turn around, it will turn around too. It uses the built in compass for this.

Can you post the document numbers, I can't find where these texts are in the original pdfs.

ah, found it - this is from the 'Court Records' part.

I was a bit disappointed that he did not in fact solve all billions/trillons of possible sudoku puzzles.

Did anyone note that there is no cryptography involved in this way of extracting book contents?

After researching the webviewer, and finding basically the same as pixelmelt, I found someone else already made the script,

I've been using https://github.com/teticio/kindle2pdf + tesseract to convert amazon books to text.

So that repo also disappeared. Neither is mentioned in https://github.com/github/dmca

This seems to be an unfortunate case where a feature has a misleading name.

You already had secure and encrypted backups on your phone, which you could copy and restore, if you remembered to copy them, and write down a very long password.

The new feature is apparently a way for signal to sell cloud services.

I do think cloud based backups are very useful for less technical people. But it does not really matter if your (properly encrypted) signal backup lives on a google drive/apple cloud, or on a cloud service managed by Signal.

The encrypted backups do work, but Signal is really, really bad at indicating when and how to make them to use them for restoration. Most non-technical people I know are just resigned to wiping out their Signal history every time they get a new iPhone (and I know two people who abandoned Signal and went back to iMessage because of this), and even I've lost it a couple times.

It leaves sort of a gross taste in my mouth that a paid service is the fix for their unhelpful UX.

> You already had secure and encrypted backups on your phone, which you could copy and restore, if you remembered to copy them, and write down a very long password.

Did I? Where? on iOS I don't.

Edit: there is a transfer to a new phone thing, but that only works if the old phone still works. Which makes it not a backup (it's a transfer).

> if you remembered to copy them, and write down a very long password

All that BEFORE your phone was stolen/damaged.

Come on, $2/month is nothing, and doubtful would raise much of “revenue “. That’s a coffee a month.
