I just use my landline # or Google Voice for a tablet. It can validate using a voice call for the landline.
But yeah, I'd prefer not to have it associated with a PSTN.

"Centibillionaire" is 10 million. The correct word is hectobillionaire. I've seen this specific use more than once, it's not just Yahoo.

Gah, I forgot to fix the link - https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fcyber1.org%2F

Though it's mostly used for playing a few old games, it still has several developer's from the original systems, and is also a good place to discuss running your own system (see http://www.control-data.info/C...)

How is that a problem? If public officials can make false statements (lies), why is it worse for a "nameless Twitter staffer" to say something, whether it's true or not?

You aren't required to give it access to your contacts.

I agree that it would be nice to let it use your contacts without also doing the Contact discovery, but even if it does, they do a pretty good job of matching contacts without revealing them.

The numbers are:

Target is one block every ten minutes. The difficulty is adjusted periodically to try to hit that target. The difficulty value can be used as a proxy for how many hashes per second are being calculated by all the miners (which is itself a proxy for how much energy is being expended globally).

Approximately every four years (210,000 blocks), the reward is halved. It started at 50 BTC, is currently at 12.5, and will drop to 6.25 in about an hour. Current block number right now is 629996.

There are 100,000,000 "Satoshis" per BTC, the smallest unit of BTC allowed. Each halving rounds down, with 33 total halvings before the mining reward drops to zero, with a total of 20,999,999.9769 BTC in existence. That's in about 120 years from now.

512K RAM and 4MB flash? That's more memory than a Mac 512K (which had 64K of RAM dedicated to the display (512x342 mono) and floppy disk controller), with room for 10 floppy disk images.

The entire MacOS operating system, plus a word processing program and a paint program, fit on a 400K diskette (with some of the OS in the 64KB ROM, along with boot code).

I just spray with hydrogen peroxide (cheap and easily available), then let it dry by itself. No residue, no fumes. Will bleach colored fabrics, though.

The only thing gloves do is allow you to sterilize them more often without irritating your skin. They MAY also remind you to not touch things. Unless you have open wounds on your hands, they don't help. You don't shed nor get infected through your hands, this is a respiratory virus.

Wash your hands, much more effective than gloves.

Masks don't help with keeping you from touching your face either. They're uncomfortable, so people are constantly adjusting them. Guess what happens if you contaminate the outside of your bandana mask with contaminated gloves or hands? You now start breathing in the virus you just put all over it.

Guess what happens when you touch your mask when you are actually infectious, gloves or no gloves? Your hands are now contaminated.

Guess what happens as soon as your cloth mask has gotten slightly damp a few minutes after putting it on? Any breath that goes through it will simply pick up and carry whatever virus particles you've been depositing onto it.

The primary worth of a cloth mask is in stopping the ejection of droplets when you cough or sneeze, and somewhat less when you talk. If you keep your mouth closed, breath through your nose, and don't sneeze or cough or talk, you'll be creating about the same cloud as you would with a mask, within a couple minutes of putting it on. The mask just doesn't filter out airborne virus, and the more effective it is, the more just goes around the edge anyway.

A simple face shield is about as effective, and possibly safer (for all parties) in some scenarios.

I agree that the valved masks aren't effective at preventing you from infecting others. Both the inlet and outlet valves should have EFFECTIVE (and replaceable) filters on them. Make them big enough, there shouldn't be too much difficulty breathing through them.

There are plans available (3-d printed parts) for modifying snorkel masks to filter both incoming and outgoing air. Some of these designs have been tested extensively (by qualified researchers), both for safety and efficacy, including ability to sterilize after use.

A lot of those are overlaps between different Android versions (so Contacts includes a bunch of capabilities grouped and named differently in other versions).

If you don't want to share your location, then don't enable it. If you don't want it to handle SMS messages, don't enable it. If you don't want to send files, do voice or video calls, use your contacts list, don't enable those permissions. It works fine with all of that turned off.

If you're paranoid, check out the source and compile it yourself. If you're even more paranoid, run your own server and get your friends to run a modified client to use it.

My main problem with Signal is only allowing identity based on phone number.

Signal doesn't require any special permissions.

If you don't give it permission, it simply doesn't give you that capability. So, microphone, no voice. No camera, no video. No contacts, use numbers only. No storage, no file transfers.

It works fine with not having access to SMS, you just can't auto-invite someone to start using Signal, or use Signal as default SMS app (which lets you consolidate all your messaging in one place, including secure backup of messages). Same with "Phone" access, you can use Signal for all calls if you want.

They explain each permission requested, and what it allows you to do when granted, on their permissions support page.

It still takes 112 MW to vaporize that much water per day. Unless you're shooting chilled air outside, you're either using that much power or you don't use that much water.

With one million gallons per day, you can cool about 3.7 MW by raising the temperature of the water 20 C with no evaporative losses.

To evaporate a million gallons of water a day from 20 degrees C takes around 112 MW.

In 2017, total Google data center power used was about 258 MW. Total US data center use was about 10.3 GW.
