Because 1) there is nothing in the document about it being a shared resource (copy at https://www.wabe.org/wp-content/uploads/2019/09/LSJ_Hyper_Re... ), and 2) the FBI already has such facilities, like 'Hogan's Alley' at Quantico (https://en.wikipedia.org/wiki/Hogan's_Alley_(FBI) ). There are many other similar facilities, like in Artesia, NM https://www.fletc.gov/artesia-new-mexico

Now, the document claims that this will be a "hyper-realistic" facility, and that only one company is able to provide such unique capabilities.

This leads to some obvious questions: 1) if hyperrealism is so important, why aren't the other facilities, including the FBI, already asking for improvements to their existing sites? 2) why should there be new sites for these sorts of training facilities - what tactical training abilities aren't already available? and 3) if it's so important, why isn't it explicitly being developed as a shared resource?

I think the bureaucratic is more reasonable than the one proposed by the grandparent post, that is, each federal organization acts as its own fiefdom and wants its own things. Plus, there's probably some graft - is it really the case that only a single company can provide such construction?
No, the public will pay much more than that because it is now a car part. Brand specific car parts are sold way above what an equivalent part would cost at retail. There was an interesting business model that consisted of buying brand new cars and breaking them up for parts.

Personally I think the cool part is that the complex logarithm takes the stereographic projection and turns it into the Mercator projection. That is, it conformally maps the plane onto an infinite two-ended cylinder.

The expression log(–1) = iπ more or less just tells you how to normalize the coordinate system on the cylinder. If you wanted you could pick a somewhat different coordinate system. This one is conventional and often convenient though.
Yes, busing people around in multiple occupancy vehicles does in fact reduce capital costs. That's why public transit networks in Eastern bloc countries were so extensive, often reaching every little town and village: communist economies couldn't afford to produce enough personal vehicles, so they ran buses instead.

But, reduced capital costs is evidently not what people in developed economies are actually necessarily after. Turns out, people are perfectly happy to spend extra resources to acquire exclusivity rights to a vehicle, because of flexibility it affords them. Having a private transport allows you to go where you want, when you want, and in almost all circumstances do it much faster than via a bus. The opportunity cost of time spent walking to bus station, waiting for a bus, and then taking longer to travel is for many people very significant, thus they pay for private transportation to recover some of that time.

The thing with actually self-compiling is that you need language features such as file management, which are not trivial and would take time that we don't have in a compiler course to cover. There is already so much to be said about compilation, and generally the course must also cover assembly language and hardware architecture at least.

And 1hp is actually 745.7w. It makes very little difference with regards to the big picture of whether something is feasible. Whether you tell someone the ferry is going to need 20,000 solar panels or 5000 it's still way more than reasonably be put onboard.

The solar factor usually employed in the UK is about 0.1 to get from nameplate capacity to actual production (accounting for hours of darkness and suboptimal atmospheric conditions) so it would be reasonable to assume your 300w is actually more like 30w.

At least some percentage of solar panels on our hypothetical solar power ferry are likely to be in shade or not pointing directly at the sun. Then you have various conversions and charging losses to get the power into a usable form.

I cant really answer that, as i never had any contact with an US curriculum.

The introduction of the ECTS was however highly controversial at least in Germany. Before the Bologna Process German universities had the "Diplom" taking no less then 4,5 years for CS. The introduction of the bachelor with down to only 180ects, so only 3 years, was seen as cheapening the education severely. Universities generally dont see themselves as preparing you for the job market, but instead provide you with the prerequisites to enable you to contribute novel ideas to your field in form of a doctoral degree. That almost every CS job requires at least a bachelor degree is just an side effect from the point of view of the university. An often mentioned criticism was the government selling out the education system so companies could quicker get new employees. Quantity over quality. As a result, you still find a high percentage of students automatically adding a masters to get the equivalent of a "real degree", with some universities not changing much in the structure of their diplom curriculum, awarding you a bachelors degree after 3 years but expecting you to finish the rest.

There is however also the opposite in the form of an (payed, but badly payed) 3 year apprenticeship training after school. You can become an "IT specialist" without going to university and even without the prerequisite school years to start university (normally successfully finishing grade 13 and thus getting your "Abitur"). You can start the training once you successfully finished your 10th schoolyear and thus getting your "Realschulabschluss". The 3 years are 50/50 professional school and working in a company. Looking at the curriculum of one of the first schools in google, they have in total between 880 and 960 school hours. Depending on your focus, 300-400 hours of "Information and telecommunication systems", 200-300 hours of application development, 200 hours of econ and business processes and ,due to accepting people who finished with 10th grade, 60-100 hours of English lessons. IT specialist here means either becoming a sysadmin or a coder.
As a remote worker, I think there is an assumption of 'necessary common suffering' which continues to make remote work a 'privilege' rather than a simple logistical alternative. So long as there are on-location cubicle-dwellers who might get disgruntled to know that other employees are living some kind of fantasy high life from home (working in PJs, etc., all the tropes), then providing any remote working options becomes a potentially destabilizing force for a company.

Making a remote worker's income less attractive is one way to redress that balance of perception.

I'm not sure how much progress we are ever going to make towards remote working as core practice, since the last decade has re-built a collapsed economy on the basis of hyper-inflated urban property values in 19thC-style urban conurbations such as NYC, SF, Tokyo, London, etc (and, increasingly, smaller satellite cities that had not benefited in this way until recent years, but have now become super-distant commuter communities).

The net-enabled, 'dispersed' society is probably further away than it has ever been because of these factors.

But in the physical reality that we live in, individuals don't exist "on their own", they don't exist as completely separate entities. They have a lot of personal thoughts and experiences, but they also have a lot of traits that are predetermined by their culture, family, education, nation, society values of their immediate surrounding etc. It is just not honest to only treat people as individuals when there are obviously parts of them which are decided by the nation. So that's why people think in nations.
I'll clarify a little: I know basically nothing about the games industry, so my thinking was along the lines of...

Many years ago, when social media was just starting, maybe somebody thought "Wouldn't it be cool if we could share photos so that we knew what our friends were doing." At the time they might not have forseen all the negative outcomes, the social anxiety, addiction, body dysmorphia, bullying, etc... caused by our buggy psychological processes.

In a similar way I was wondering if the first developer that thought about adapting the normal random item drop in a game and instead making it a purchasable mystery box, actually realised that this fits the definition of gambling and the myriad legal and moral problems that introduced.

In the present day I'm sure there are plenty who know exactly what they're doing or are willfully ignoring the moral issues around loot boxes. But quite often how something is today doesn't fully explain how it started.

Not sure how it's going to help you win any argument. Overwhelming majority of cost is wages and benefits of the employees, and right after that it's fleet amortization and fuel costs.

I was prepared for most of the details, but that caught me by surprise. So you can't trust what a cable is marked with or advertised for by its manufacturer, but have to check every cable using software.

Thanks but no thanks. I read some posts and the guides they have.

Is it possible for a government to provide a high level of services to it's citizens while having no border?
I have a question that is tangentially related to the point you were making, but it's been bugging me lately, so here goes.

Everybody says 'the robots are destroying jobs' but the unemployment rate (in the US at least) is very low right now. If AI is taking all the jobs, how is the unemployment rate so low and the economy booming?

The possibilities I can think of:
- AI is creating jobs at the same rate it automates them. The new jobs may not be as good as the old jobs, or perhaps they require people to totally retrain which isn't always feasible. But people need to make a living and they adapt because they have to.

- Lots of people have given up looking for work.

- For the most part, AI is augmenting rather than replacing humans.

- The full impact of AI on our society has yet to be felt, and we should brace ourselves like the rich techies building compounds in New Zealand.

What do you think?
Tens of thousands of euros saved is pretty much cost of running one extra bus for a year. So no, I don't think it's going to make a huge difference.

> If this was true we should have the right to enter any country we want as long as we align with its culture.

It seems most people would be ok with that, yes. The question is of course of the practicality of determining someone's culture to a great extent, when there would be incentives for them to lie on the applications, interviews about their culture - if that would be the deciding factor (in some countries it is) for getting into the country or not.

> Can you provide a list of values that make you suitable for your country?

You have probably a favorite style(s) of music and other styles that you don't like. Can you really provide a list of traits of that music taste exhauistively and exactly? Probably not, and it's not because it's random. There are definitive differences in those styles, and yet it can be very hard to pinpoint them. And now we are talking about one individual, and you are asking a question about something much more complex, like a nation. Not being able to list the values exactly in all cases does not mean that there are no values or that they are meaningless or have no effect on people.

> would it be ethically acceptable to run value exams on citizens and non-citizens to decide who can enter

Some countries do that already. It might not always be in the form of simple written exam, but there are people who determine your cultural values and make a decision on whether you can stay or not depending on them.
To gain an understanding of what a near-useless idea it is to put solar panels on a tesla, go here:

https://pvwatts.nrel.gov/

plug in a prototypical 1000W PV system at your latitude and longitude, as if it's on the roof of your house. That would be four 250W panels.

Look at the kWH produced per month in mid summer, and again in mid winter.

Using Seattle as an example, estimated production of 147kWh per month in mid summer, and 34kWh in the worst month of winter.

Now look at how many kWh the capacity of a tesla battery (70 or 90 or 100kWh) is for a single full charge.

147, divide by 31 = 4.74kWh per day

Those estimate figures for pvwatts are pretty rough, but they also calculate based on having near direct sunlight from sunrise to sunset, as if the PV panels are on the roof of a building or an unobstructed ground mount. Cars are frequently in the shade.

Realistically, if you were to somehow magically cover a Tesla in 1000W of PV, and it was all flat-angled optimally to catch the sun, you might get 3kWh a day if you were really lucky.

There is really no practical reason why the photovoltaics needs to be ON the car. Putting high efficiency pv cells on curving surface is expensive and hard. The PV can be on a roof mount covering your closest grocery store, home depot, car repair garage, public school, and so on, feeding the grid.

I saw the scooter/motor bike craze in India and I have to say I was not impressed. It was a necessity, yes, but instead of everyone riding million scooters public transport should be the main mode of transportation for majority of people in big cities. The traffic is already too congested and with every oil-burning vehicle out there unsustainable.

I would like to have an explanation why "going after the unions" is a thing and what it means in this context?

I can understand for example limiting striking by law or similar ordnances to uphold order and democracy. Is this all the parent is talking about?

But isn't a union basically a private organisation formed by citizens by their own free will?

What does it mean for a political organization, eg a party, to go after something like that? I mean from liberal/freedom of the individual POV.

I'm most certainly missing something important here and me being european/nordic shows ;)

That's a great way to get your bike stolen. Not only that, it's also quite significant additional cost, because now you have to buy and maintain two bikes. At that point, why not just take a car?
> I always assumed afterburners just meant opening the throttle up but there must be more to it

No, as the name implies it's literally pouring in fuel after the turbine, in the exhaust. The exhaust is hot, yes, but cooler than the combustion chambers (which reside in between the turbine and compressor). So if you have some special fuel that's very hard to ignite then maybe you need some help to get the afterburning started.

My friends and I got very into Ingress [0] back when they only had 8 levels. Now that was literally a predecessor of Pokemon Go; I hear they used the portal data from the former to choose pokemon locations in the latter. Ingress seemed a lot more fun because you could be truly competitive, destroy other players' constructions and gain territory in your home area. There was even a running global count of how much territory each of the two factions had. That said my Pokemon career began and ended with Yellow on the game boy.
