This has to do more with the fact that physical objects wear out and digital objects don't. Publishers have complained that when a library lends a physical book, it can only do so for a limited number of times before it has to buy another copy because the first wore out. When libraries lend digital objects, they never have to buy another again. So publishers want a limit to the number of times that a digital object can be lent before requiring a repurchase. The same goes for CDs/DVDs.

Already found two point of interest location errors and reported them!

What if God created the universe 6,000 years ago and when he did he put in place evidence that indicates a 4.5 billion year old Earth and a 14 billion year old universe? Why did he do that? To test our faith!

I work with Industrial Automation Software. I have developed the software and installed it a customer sites. Any customer that depends on the vendor to always install the software is courting disaster. What if your critical enterprise software is custom installed, runs for five years and then due to a hardware failure you need to reinstall from scratch? Will the original person who did the install still be available? Is the software still being supported? All end users should have explicit written instructions for how to install the software. The industrial automation software I use can kill, cause fires, and do all manner of damage if not installed and configured properly. It is just good practice to have explicit detailed installation instructions, that someone with a modicum of knowledge of the system can follow to reinstall from scratch. I've seen plenty of customers who are using software for which they have no idea how it is configured or installed. The original engineers are no longer available. They were laid off in cost savings events. Then I have to come in to figure out what they have so that I can determine how to upgrade them to the latest version while preserving years of data because once the hardware failed you can't get it to use the old software and the old software won't run on newer hardware.

I guess you don't understand International Business 101.

I was not addressing the gray market, I was pointing out why Aussie prices are expected to be higher than US prices.

Most companies require their country divisions to factor in the costs of doing business in that country to the prices they charge in that country. They don't spread their costs over all their customers worldwide. They do it by maket. It costs more to do business in Australia than the US simply because of the size of the market.

Each country charges different import duties (when they apply).

By international treaties, different countries can charge different copyright and patent fees.

All these and others factor into the costs companies must recoup in the price they charge.

There are other factors including warranty costs. Different countries have different minimum warranties a company is required to provide.

Now do the price differentials also have some gouge factor built in when the "expectation" is that prices in a particular country are expected to be higher than in the country of origin? Probably.

There a number of factors that lead to price differentials between countries.

1. Tax differences - Aussie GST is 10%. No US state has a sales tax that high. Aussie prices are quoted with tax included. US prices are not.
2. Labor costs- US retail workers are paid less
3. Size of the market - Costs in the US can be spread over a much larger customer base than in Australia.
4. Shipping costs - Shipping to Australia is more expensive than to a US address, even from Asia!
5. Import duties differences
6. Copyright and patent licensing fees differences
There may be others.

If your game needs to simulate physics and your programming library and tools don't do that, you will need the appropriate equations. Proper physics equations can be complicated and involve calculus. A good example is moving a vehicle around a curve realistically. There you need math to simulate the equilibrium between forward motion in the curve and centrifugal force that want you go straight.

As long as the companies have shared resources: the boat, food, security, IT, etc. - they will be paying some form of taxes even if the boat owners call them fees.

But what if one site only allows lower case letters and another requires a mix of lower and aupper case and special characters? Are you really going to remember that if you visit the sites infrequently?

We have discussed this ad nauseum - still nothing gets done. We have way to many passwords to remember. We have way too many different password policies to follow. What is a valid password on one site is not at another. It takes too much time to look up a password you have "written" down and you need a separate password to get into the list!. That supposes you have the list with you when you need it. Today the internet is mobile and not just used at home or at the office. Additionally, there are sites whose compromise could ruin you financially or ruin your reputation and sites where compromise doesn't matter. So most resort to a few easy to remember passwords, phrases or algorithms and these are probably easy to crack.

It's not clear what could be done. An RSA key fob and biometrics need a reader. You have to remember to have the fob with you. The blind can't read it. All this costs extra.

So many science fiction stories have shown that one can simulate gravity with centrifugal force by rotating a craft/station. Why don't we do this with the international space station?

These pictures should be at least 100MB+ in size! How long will it take to save to SD card, and how big a cache is needed to do multi-fps pictures? Also how long would it take to upload these to a PC?

What if you were arrested for shoplifiting in a small town where the newspaper publishes the daily arrest record online? Later you are convicted and your sentence includes getting your record expunged once you serve your community service. However, the record in the paper of your arrest is not. The town doesn't have the power to tell the paper to expunge your record. A background check might find that arrest, but not evidence of the outcome. Now you could lose jobs, security clearences all for something that is not supposed to exist. When your record is expunged, you are supposed to be able to answer no to having been arrested, but the internet says otherwise.
