I think your mental model of how blackwater (and other contracting firms) works is off.

Might not be true as more problems are solved through machine learning. Amazon has or could generate the largest and most diverse dataset to train the object recognition problems needed to automate a warehouse. They also have the end to end pipeline to evaluate accuracy (damaged or incorrect orders, manual intervention needed in the warehouse).

Can a competitor actually catch up without this data?

Japan has had mobile NFC payments for over a decade now (back to the dumbphone era), and while it's heavily adopted by chain stores; smaller shops, restaurants and bars have never really adopted it due to the onerous setup, hardware, etc.

In the past 6 months or so (so basically overnight), a QR payment system (PayPay) has gotten massive adoption. They did this in two ways: a massive expensive signup campaign (20% cashback on all purchases deal), and the fact that any tiny back-alley bar can just install the app, link their bank account, and print out a QR code and now they're accepting payments.

The big advantage for QR is the quick and cheap deployment process.

> "Environmental group Greenpeace"

Let's be honest here, Greenpeace is an environmental group the same way PETA is an animal rights group.

One thing I think a lot of people forget is that many of the same problems that nuclear has are issues with other power sources. For example, coal also has radioactive waste. To put it into perspective, an average coal plant produces 5-10 tonnes of Uranium and Thorium ash per year.[0] Let alone the 400tonns of coal ash. I should also note that ash is more dangerous.

I'm not trying to say here that these aren't concerns. But I'm trying to say that when people mention these things that it always feels either uninformed or disingenuous. There is an issue of scale, so if the concern is about radioactive contaminants then we should be prioritizing the one that is producing more.

> That's really not a lot.

Which shows an understanding of scale (which is difficult). For reference, total waste per person from most nuclear powered countries is about a liter bottle per year, which only ~3% is high level waste[1] (~30ml, < a 10th of a soda can). So taking into account the scale, even when including toxicity and radioactivity, it is still one of the cleanest forms of energy we have. But the reason for that is scale. More radioactive, more toxic, but magnitudes less waste.

I’ve always been taller than average. In school, in a class of ~30 students, I was probably in the tallest 3-4 students.

At least the best at marketing. A big time operator friend of mine, with a fleet of predominately Deere equipment, ordered a new CaseIH tractor a couple of years ago. Before it even showed up on the farm, John Deere caught wind of the purchase and swooped in to make him an offer he couldn't refuse, buying out the never used CaseIH tractor from him, and getting him into a green machine instead.

Of course, us smaller farmers look to what the bigger farmers are doing to gain some insight into how they are successful, as people do. When you see the big guys running Deere equipment, it is easy to think that Deere helped them achieve the success they have, and if you buy Deere equipment you will also be successful. But there is some smoke and mirrors going on.

I have a few different brands on my farm. As far as getting the job done, I'm not sure any are better than any other. They all break down just the same. However, John Deere does seem to have an edge on operator comfort. Which, admittedly, is nice on the long days.

One of the more influential papers on my early thinking of distributed systems was the Xerox paper on Grapevine, their distributed naming service that used a viral model for propagating updates across their networks.

The most interesting part was transmitting 'dead' information. In the linked article things are alive or not. Now expand this article so that you have a series of things that are being transmitted (maybe blue, red, and green dots to represent each). And then you want to 'kill green' so that green is no longer considered a valid state. Networks need to retain the notion of a tombstone (in epidemiology a residual antibody) to quash flare ups of previously killed information (which can happen when a node that has been down for a while rejoins the network).

It makes for some great coding exercises!

This is exciting to see on the front page. If anyone’s looking for more in depth reading on the subject, I highly recommend Mark Shepard’s book, “Restoration Agriculture”. In it he gives a good overview of farming with perennials, and why it can be beneficial for the planet.
The U.S. president has been accused by multiple women of sexual assault. He has called women bitches, whores, fat pigs, ugly, etc. Multiple states in the south passed legislation effectively banning abortion, stripping women of their sexual and bodily autonomy.

Public pensions like the ones in Canada would be nice. From both the worker and government perspectives, they provide a lot of stability and can be planned for. Of course, it won't happen in the USA, I think, sounds too socialist for many people on the right.
I agree, I believe in this day and age it is nearly impossible to discuss any possible correlation between any sort of innate/genetic differences (and often even early-learned cultural differences) and mental ability without being branded a sexist/racist etc. No matter how many caveats one offers, no matter how strongly one emphasizes that it could be one, even a tiny one, of a number of factors that account for differences in achievement, it is basically not discussable without grave risk to one's profession and reputation. I find this particularly surprising because physical performance obviously has such an enormous genetic component.

Tennessee had a budding green power sector back around 2005. TVA nuked it with absurd, arbitrary restrictions on who can put up solar panels on their houses because TVA is in bed with the coal operators and green power was competition they didn't want. It kills me to think about how much more money this state would have in its economy now if that hadn't happened.

There's reasons the whole "just replace coal jobs with solar jobs" thing has never played out. It's not for a lack of trying or because nobody here ever coming up with the idea. It's because the powers that be sure as hell weren't gonna let it fly.

(TVA continues to be the least green utility in the South btw. Promotion of the welfare of the people of the Tennessee Valley my ass.)

I remember reading that NASA's psychological selection/screening process is top secret or something like that, but if you read between the lines and analyze the astronauts themselves, you quickly conclude that yes, if there is fuel and a giant unexplored opportunity nearby, don't get in their way. Not only are they adventurous, but they will push just about any boundary; that is their default setting.

Sometimes there are "interesting" incidents where you get to see this psychology in weaponized form, like the Terminator-esque jilted astronaut lover story from back in 2007. I'm not surprised at all to hear that contingency means might be taken to limit related risks on space missions.

The main issue is that tolerance to all the effects of the drug doesn't increase uniformly. Originally I was on 70mg for about 5 years but started to notice that it wouldn't last the whole day anymore. My doctor gave me a booster which worked well for about a year but slowly I started to realize that the side effects were becoming worse than the desired effects.

My main issue was that originally it gave me a calm and relaxing feeling but over time I began to feel more an more anxiety. I'm not normally an anxious person, and the first time I an anxiety attack I thought I was having a heart attack and went to the ER. Magnesium, L-tyrosine, and good sleep can help but eventually, it would just make me feel jittery and unfocused. The anxiety also caused me to subconsciously swallow air and combined with the increased water I would drink it started to cause me stomach issues. I suspect the excess water diluted my stomach acid causing my stomach to make more. The swallowed air put pressure on my esophagus and eventually, I developed a hiatal hernia. This allowed my stomach acid to start damaging my esophagus and would result in constant burping / GERD.

The worst part is that the GERD was anxiety induced and things like Tums or even Zantac or Nexium did nothing. The only thing that worked was Xanax. However, Xanax is an incredibly powerful drug that can cause bizarre behavior because sometimes you speak without a normal filter. I didn't like the concept of having to take another powerful drug to counter the side effects of the first powerful drug, nor was I comfortable with medication effecting my personality. Furthermore, because of the stomach issues, I began to feel like I needed to make a change because it wasn't sustainable. I began a regiment to taper off by reducing the dosage and stopped taking it daily.

It wasn't as bad as I thought because what I realized is that the original effect that helped me just didn't work anymore and I really hadn't felt it in a long time. In many ways, that slow reduction of effect over time trained me to be able to do work without it. By the end, I was more productive without it because I wouldn't have the stomach/anxiety issues. Furthermore, my sleep has never been better.
Yes, Elizabeth Holmes was a fraud. But choosing to lower your voice to have a more commanding presence does not seem fraudulent not particularly "cartoonish" to me. Regardless of ones feelings towards Margaret Thatcher's policies, Thatcher was most definitely not fraudulent, and her lowering her voice was almost a virtual necessity in her political era.

First you said I was repeating what you said, now you are saying the opposite?

Various good sources [1],[2] state that the issue is lift, not thrust. The article I linked to from my earlier post shows that this lift is not unique to 737 Maxes, and that it contributes to the stability of the DC-9, on account of being behind the CofG on that airplane.

The LEAP-1B engines of the Max variants are not significantly more powerful than those on NGs (they are more efficient and somewhat quieter.) As the whole problem arises from the fact that they cannot be mounted lower, it seems unlikely that an increased thrust moment is what is making the Max handling unacceptable.

> If the thrust gets high enough, at some point this pitch torque would overwhelm the natural tendency of the airplane to pitch down as airspeed goes down and result in negative longitudinal stability.

There seems to be some confusion here over what longitudinal static stability is: it a matter of the rate of change of pitching moment with respect to AofA (take a look at the links in my first post for data from real airliners, where a negative slope indicates stability.) Thrust is not a function of AofA, and consequently is not factor in the relationship that gives longitudinal stability of ordinary airplanes - and, as I said before, neither thrust nor any proxy for it is an input to MCAS (while AofA is.)

I might spend a week prototyping something.. perhaps stabilised using very small high speed brushless motors for gyro effect, with some flexible/springy elements. The motors cost $5 or so each online. The design would be open source.

I'm not familiar with the disability however, I'm not sure which axises of motion need to be stabilised.

Get in touch if you are interested, my email is in my profile.

EDIT: What about EMS pads on the major arm muscles, accelerometer/gyro chip on the pack of the palm, and pipe it into a machine learning system that figures out the correct stimulation for stability? Is that a thing?
Uranium is also toxic. The personnel that used DU ammo has mainly lung diseases due to Uranium dust. Metal toxicity has nothing to do with radioactivity.

That's not something unique about "this new court". The Court has never been all that respectful of precedent. From the Lochner era (reading a right to expansive freedom of contract into the constitution), to the "switch in time that saved nine" (vastly expanding the definition of 'interstate commerce' such that Congress could regulate anything), to the Warren court (which invented whole-cloth a slew of social and criminal justice rights), the Court has often gone in radical new directions and overruled previous decisions.

I'm really no expert on the whole BPA thing, and I've read a lot of mixed research about it. I say "considered" toxic because of some of the research that has come out about it. I think ultimately we're not totally sure of the impact it has on health. There are quite a few studies done on this so far but none are particularly conclusive.

Here's one relating to cashiers:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4824622/

And a more generalized one relating to factory workers who produce products containing BPA (like thermal paper):
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5634705/

It seems the government of France is also taking a stance against the use of thermal paper in the EU. There have been some concerns about BPA levels in groundwater, too, but this would be from all sources of BPA that end up in landfills, not just thermal paper.

Calling it "highly" toxic might not be entirely accurate when compared to something like radium, but one of the issues with BPA is we're not entirely sure of the health impacts. As a hormone disruptor, it seems to manifest in undetectable ways (links to heart disease, infertility, etc.) so it may be hard to pin down the effects of exposure until enough historical data has been gathered.

According to Health Canada (my country) 92.7% of their sample population had BPA concentrations in blood, a number that actually increased in the 7 years after it was banned from consumer products. (https://globalnews.ca/news/3694669/bpa-blood-samples-common/)

I'm also not trying to call for an immediate ban on it or anything like that, but merely stating that creating more of it without solving this problem is probably not a great idea.

I don't know about South America, but in most parts of Asia, the data is unreliable because a) poor rural people don't always get treatment, and even when they do, the diagnostics aren't always correct or even reported, and b) data collection is poor in rural areas - both the quality and quantity.

So I'd take any statistical claim with a grain of salt.
Understanding existing codebases is something that takes experience, time and drive (money, rep, etc). There are some codebases that I had trouble with because they weren't even decent. Tools like grep, looking at previous commits and an open notes file are good tools.

There was pretty much nothing going on in terms of nuclear power development in the US between 1990 and 2008 or so, and Watts' Bar is the only reactor to come online in the US in the last 25 years. Fracking wasn't the cause of that lull.
Yes, monitored remotely through the app on your phone, which may or may not reflect the actual environment in the car at that moment.

FWIW is typical failure mode for an air conditioner is for the condenser to fail, so the conditioner ends up over-heating air that hasn’t been cooled by the condenser yet, resulting in the interior temperature hitting 60C in minutes, so eg a police dog (typically a large-ish dog like German shepherds) will be dead or dying when you come out to check on it fifteen minutes later.

The systems used in police dog vehicles include redundant components, temperature monitoring and emergency actions like opening windows to allow cool air to flow. Police around the USA still lose about one dog a month with those specialist systems in place.

It’s only a matter of time until someone posts on the Tesla reddit that the car killed their dog and the fans will dogpile on the poster telling them it’s their fault for leaving the dog in the car in the first place.

My understanding is the top-end model was $600 at launch. The price was cut by $200 to $400 two months after launch; after a backlash Apple compensated early purchasers with $100 of store credit. Two years later, an iPhone with comparable specs to the $600 launch model was $200.
