A Google login, whether you get it via gmail or "G Suite", ties into all of the Android apps and keeps search history and integrates it into other Google products, and runs synchronization of most app data so they can see a great deal of what you do on the phone. About the worst that you can do is turn on device management. It will take about two days to turn off and during that time it will do its very best to force your email users to put their devices under your control. After that you apparently even have control over booting of the device. It's enough to make me want to support another open phone. Mozilla just gave up the ghost on that.

Military meals are designed with attention to the morale factor. Even the modern MRE is designed to help the soldier feel human in unfavorable surroundings. Apollo 10 was the first to officially test real bread. Gemini Astronauts smuggled aboard a kosher corned beef sandwich but it was stale and thus had too many crumbs which went airborne. By Apollo 10 it was discovered that nitrogen-flushed bread would stay fresh for 10 days. I'll have to try that.

Comment But then who audits the auditors? (Score 1) 183

The solution is pretty simple, but often skipped:
1) The reason for every search should be required and logged by the searcher. ...
2) The logs be randomly spot-checked by an auditor(s) who verifies the reasons given by interviewing the person(s) who searched.

But to check it the auditors need detailed access to the records. So who audits THEM?

This kind of question has been asked repeatedly since at least the Roman Empire.

(The U.S. answer to "Who guards the guardians?" , at least for direct abuse of person under color of law, is the Fourth and Fifth amendments and the "fruit of the poisoned tree" doctrine: Fail to follow the law and you don't get a conviction, because misbehaving police are FAR more of a problem for the population than even a lot of violent private-enterprise crooks going back to work. But while it does reduce the incentive, it doesn't block the behavior.)

Comment The invisible hand strikes. (Score 4, Interesting) 124

Not one organization I have ever worked for has seriously cared about IT security.

When it comes to rolling out new products, ignoring security is the norm.

This is because the "window of opportunity" is only "open" for a short time - until the first, second, and maybe third movers go through it and grab most of the potential customers. Companies that spent the time to get the security right arrive at the window after it closes.

This happens anywhere the customers don't test for and reject non-secure versions of the "new shiny" - which means enterprises sometimes hold suppliers' feet to the fire (if the new thing doesn't give them an advantage commensurate with, or perceived as outweighing, the risk) but consumer stuff goes out wide open.

Then, if you're lucky and the supplier is clueful, they retrofit SOME security before the bad guys exploit enough holes to kill them.

I expect this will continue until several big-name tech companies get an effective corporate death penalty in response to the damages their customer base took from their security failings. Then the financial types will start including having a good, and improving with time, security story (no doubt called "best practices") among their check boxes for funding.

And the reason you cannot do this with radio is that the noise from the transmitter is greater than the received signal.

Actually you CAN manage it with radio - very difficultly, with very careful antenna design.

But the combined antenna has to be far from anything that reflects, absorbs, or just phase-shifts any substantial amount of the transmitted signal energy. If not, the discontinuity destroys the careful balance that nulls out the transmitted signal at the receiver. That gets you back to the "transmitter shouts in the receiver's ear much louder than the distant communications partner" case. So it's not very practical in the real world.

but what are the chances of finding a good vintage of scotch to go with all of this breaded goodness they are going to be having up there?

Alcohol is definitely going to space. Ballantine's zero-gravity glass is made in cooperation with something called the Open Space Agency, which also has a design for an automated Dobsonian telescope. Ardbeg is going to space. And a vacuum still is an old science-fiction trope.

Comment Re:Everybody should be prepared to die. (Score 4, Funny) 459

Out of several tens of billions of humans, only a fraction have not yet died, and of those who died, only a small percent of disputed cases indicate recovery.

On the contrary, I have never died before and rumors that I would do so are spread by fact-checkers of the liberal press and corrupt global warming scientists.

Comment Some Artistic License (Score 1) 459

I like the part in the SpaceX video where the rocket lands, and the door opens on magnificent desolation. This is artistic license. Obviously the material for a habitat would precede the arrival of people.

But yes, a first-try planetary colony won't necessarily work. Getting there is dangerous, and once you're there being able to continue to provide the population with air, water, food, shelter, and energy is going to have significant risks of lethal failures.

Coax is half-duplex too

No, it's not.

With proper impedance matching networks and reasonable termination at the ends of a run you can send separate signals at the same frequency/band of frequencies down a cable in each direction. (Impedance discontinuities DO reflect some of the signal going one way back the other way, causing some interference. But even that can be "tuned out" by suitable corrections if it's too severe to just ignore.)

You can do it on a balanced pair, too. Telephones have done this with audio for more than a century, and I recall encountering a simple hack to do it all the way down to DC back in the days of discrete-transistor logic. (And it has nothing to do with two wires being involved, either. With N (= any power of 2) conductors and "phantoming" you can have up to N-1 balanced and one unbalanced two-way transmission lines on N wires.

Time Domain Reflectometry does this to FIND and MEASURE discontinuities in a cable, essentially firing a pulse down the cable and listening to the reflections, radar-style.
