"It's not like SpaceX did not have any missteps on their path to creating reusable boosters."

They weren't really missteps. It was part of their design philosophy. Build it enough to get past a "goal" (say, get past the launch tower) and test. If it doesn't meet the goal, ID the failure, redesign and test again. Once it reaches that "goal", create a new "goal" (sat, reach 20,000 ft). Repeat until it's reliable.

While this involves a lot of explosions, the actual time it takes to get a workable and reliable rocket was dramatically reduced.

Looks less like a failure on China's program and more like China learning from Musk.

Telescreen monitoring would have required a crazy amount of manpower.

Probably the closest real-world analog was the East German Stasi, which may have accounted for nearly 1 in 6:

The ratio for the Stasi was one secret policeman per 166 East Germans. When the regular informers are added, these ratios become much higher: In the Stasi's case, there would have been at least one spy watching every 66 citizens! When one adds in the estimated numbers of part-time snoops, the result is nothing short of monstrous: one informer per 6.5 citizens. It would not have been unreasonable to assume that at least one Stasi informer was present in any party of ten or twelve dinner guests. Like a giant octopus, the Stasi's tentacles probed every aspect of life.

In the USA is it common to have self service tills at supermarkets that accept coins?

If it accepts cash, it should accept both coins and bills. Any change I manage to accumulate usually gets fed into the coin slot at a self-checkout before I swipe a card to provide the rest of the payment. It's better than handing it off to a Coinstar machine, as those skim off a percentage of what you feed them.

"I like things simple. I really don't deal with milage, or all the other things I consider minutiae. I deal with simple numbers. What this means is not filling out milage reports and the other stuff that clutters up to work. Perhaps I'm eccentric. But I like simple because my actual work is quite complex."

As is my work -- however, my mileage report isn't "minutiae". It' averages $300-$500 every two weeks (I do a lot of driving --- particularly for projects). And the process isn't complicated. Basically a date, destination and total miles per line. In a text file. No clutter -- just a review of my travel calendar for 5 mins every two weeks and another 2-5 mins to transfer that to my expense report. Automagically appears in my pay check 8 days later.

"I take it you don't get a salary? That you get paid by the second?"

I'm an "exempt" employee in California. Salary for over 2 decades.

I also turned down a company car to use my own. I get paid for "miles". $0.70 per. I do not get paid miles going to my office-- but from my office to any given site. At least during M-F. Sometimes I need to hit a site on the weekend, and miles start the moment I leave the driveway of my home.

There is zero expectation that my 8 hours start when I start my drive in to the office. It starts when I arrive. And yes, it's not uncommon (particularly during projects) that I work well over 8 hours. When that happens, we get comp-time at some point in the future.

"People expect to be paid for commute time too, at least in the sense that they will want more money if the commute is longer. Work from home made just coming to the office at all something which people want more money for."

People (employees) make that choice. They might take a longer commute for a job that pays more. It's not up to the employer to PAY for that commute ON TOP of their pay rate for a given job -- at least in my opinion.

I stand by my comparison. If the tool I'm provided is an employer-provided workstation, I should get paid the moment I start using it. If the tool I'm provided is a citrix session across a secure connection, I should get paid the moment I connect to it from my home PC.

Don't like the commute analogy?

I think that might matter. Running software through something like a citrix session via a secure connection on their home PC might negate any "when did they actually start working" argument. Much like I don't start getting paid the moment I hop in my car to go to work.

Kind of like a "digital" comminute.

Manufacturer Remotely Bricks Smart Vacuum After Its Owner Blocked It From Collecting Data (tomshardware.com) 123

"An engineer got curious about how his iLife A11 smart vacuum worked and monitored the network traffic coming from the device," writes Tom's Hardware.

"That's when he noticed it was constantly sending logs and telemetry data to the manufacturer — something he hadn't consented to." The user, Harishankar, decided to block the telemetry servers' IP addresses on his network, while keeping the firmware and OTA servers open. While his smart gadget worked for a while, it just refused to turn on soon after... He sent it to the service center multiple times, wherein the technicians would turn it on and see nothing wrong with the vacuum. When they returned it to him, it would work for a few days and then fail to boot again... [H]e decided to disassemble the thing to determine what killed it and to see if he could get it working again...

[He discovered] a GD32F103 microcontroller to manage its plethora of sensors, including Lidar, gyroscopes, and encoders. He created PCB connectors and wrote Python scripts to control them with a computer, presumably to test each piece individually and identify what went wrong. From there, he built a Raspberry Pi joystick to manually drive the vacuum, proving that there was nothing wrong with the hardware. From this, he looked at its software and operating system, and that's where he discovered the dark truth: his smart vacuum was a security nightmare and a black hole for his personal data.

First of all, it's Android Debug Bridge, which gives him full root access to the vacuum, wasn't protected by any kind of password or encryption. The manufacturer added a makeshift security protocol by omitting a crucial file, which caused it to disconnect soon after booting, but Harishankar easily bypassed it. He then discovered that it used Google Cartographer to build a live 3D map of his home. This isn't unusual, by far. After all, it's a smart vacuum, and it needs that data to navigate around his home. However, the concerning thing is that it was sending off all this data to the manufacturer's server. It makes sense for the device to send this data to the manufacturer, as its onboard SoC is nowhere near powerful enough to process all that data. However, it seems that iLife did not clear this with its customers.

Furthermore, the engineer made one disturbing discovery — deep in the logs of his non-functioning smart vacuum, he found a command with a timestamp that matched exactly the time the gadget stopped working. This was clearly a kill command, and after he reversed it and rebooted the appliance, it roared back to life.

New Large Coral Reef Discovered Off Naples Containing Rare Ancient Corals (independent.co.uk) 13

Off the southwest cost of Italy, a remotely operated submarine made "a significant and rare discovery," reports the Independent — a vast white coral reef that was 80 metres tall (262 feet) and 2 metres wide (6.56 feet) "containing important species and fossil traces." Often dubbed the "rainforests of the sea", coral reefs are of immense scientific interest due to their status as some of the planet's richest marine ecosystems, harbouring millions of species. They play a crucial role in sustaining marine life but are currently under considerable threat...

hese impressive formations are composed of deep-water hard corals, commonly referred to as "white corals" because of their lack of colour, specifically identified as Lophelia pertusa and Madrepora oculata species. The reef also contains black corals, solitary corals, sponges, and other ecologically important species, as well as fossil traces of oysters and ancient corals, the Italian Research Council said. It called them "true geological testimonies of a distant past."

Mission leader Giorgio Castellan said the finding was "exceptional for Italian seas: bioconstructions of this kind, and of such magnitude, had never been observed in the Dohrn Canyon, and are rarely seen elsewhere in our Mediterranean". The discovery will help scientists understand the ecological role of deep coral habitats and their distribution, especially in the context of conservation and restoration efforts, he added.

The undersea research was funded by the EU.
