There tends to be a commonality with Europeans to ignore problems of their own. If this was an American project, they will be in full flame on stating how this mission was a complete failure.

Echo location isn't about removing the blind persons need for a cane, even with people who are good at it are still recommended to use a cane because things like grates, poles, or holes do not work well with echo location. As the sound passed threw it and back.
What it does mean is with the aid of a cane and the watch they will be able to move more quickly with more assurance that there isn't something big going to be in the way.

Yes it would be.
However if the point was teaching nested loops and you gave the simple loop answer. You may have gotten points for being clever. However the actual point was about teaching how to use loops.

An other example is a program to say power a number. This can be done via a loop or really small with recursion.

If you are dead, you don't know you are dead but all the people you know are effected from your death.

The same is true with Stupidity.
Your Incompetent boss doesn't know that he is incompetent, yet we all suffer from this.

Because every successful tech company keeps the same business model for over 30 years!
Lets face it.
The Desktop Business isn't where the money is anymore. The Desktop is a dying idea. It is shifting towards Servers,Workstations, and Mobile.

New applications take more advantage of the Web Standards, and less of OS dependent technologies. (With the key exceptions of heavy processing systems (Such as CAD, Games, Simulations, Programming)
The nice thing about following web standards for Web Applications your program is in essence write once run everywhere.

I don't think it is a case of regularly. But it happens a few times per month.
But there is a big difference in doing this for your work and doing it for school.

If you are doing this for work, your goal is to get the computer to solve the problem.
For school your goal is to learn how to get the computer to solve problems.

For Example a CS101 student will have a nested for statement that displays a triangle in text.
The point of the exercise isn't about having a triangle to appear. But to teach and impress the ideas of nested loops.
Now if you take the code:

for i in range(10):
    st = ""
    for j in range(i):
        st+="#"
    print(st)
print("Done!")

For a someone new to the topic. You wouldn't have realized that you needed to reset your string in the correct level of the looping. The real learning isn't about getting the program right, but finding all your mistakes in the process. Just copying the code so you got it done you failed to learn. You just completed the assignment.

Now for professional work you goal is to get the assignment done, and they really don't care if you learned something new or not. So just as long as you got that triangle even if you had a...

print("#")
print("##")
print("###")
print("####")
print("#####")
print("######")
print("#######")
print("########")
print("#########")
print("##########")
print("Done!")

they really don't care.

LINUX ISN'T A DESKTOP OS!
It is a Server OS and a Work Station OS.
I am talking about GNU/Linux base distributions not Android and other OS's that happen to use the Linux Kernel.

Gaming is never a big priority in Linux because gaming on Linux tends to stick at the novelty factor, but rarely gets serious. Sure we talk about Steam... But that is only one company, and for the most part their main reputation is releasing niche indie games.

Next you have the GNU community vocal nuts. Gaming doesn't bode well with Open Source. They take a lot of work, with a lot of talented people to make, with a lot of stuff that isn't fun. So they are expensive to make, as well because they are entertainment programs, people feel less charitable with their effort and are more out to make money with it. So you port to Linux then you get a small set of GNU nuts demanding you release your code. You are better off sticking to Windows or Macs and live well in the walled garden.

Almost everyone doesn't see themselves as the bad guy. They do bad things because in one way or an other they feel justified to do it. They will find a religious text/Constitution/legal prescience that reinforces their belief, even if it explained otherwise later on.

Now legal systems are meant to objectively look at the situation and determine if they were really justified or they were just convincing themselves to get what they want.

The biggest difference between Dial Up and Broadband. Is the following
With Dial Up the Telephone line infrastructure is already there and sent to every last mile. So everyone has access to the Telephone line. Until Recently all the infrastructure was put in by Ma-Bell which was a highly regulated by the government monopoly. So they were forced to put lines in every home even if it wasn't to their best self interests. So the infrastructure is there and it exists.
Now the dialup ISP's are not in the infrastructure business but in internet service(s) so they paid for the high speed backbone and the telephone lines to meet customer demand. But the customer had to pay someone else for phone service and the ISP for internet Service, You were just as stuck today with phone service as you are with broadband. however you had a bunch of ISP to choose from. If you paid more you may have more services (your own IP address, more available lines so less busy signals, or you can get a cheap service with just the connection and that's it. So you had some real choice.

Broadband companies you buy the infrastructure and the services in one big block. If your area only has Comcast you are stuck with Comcast, if they don't want to give you a connection you will not have access at all. So you are doubly stuck.

Why?
A phone or laptop physical presence of raw material is only a few dollars, but still even that why is material worth any money at all, you just need to dig into the ground and get it.

So this stuff cost money because of shifting of data and legal rights.
You need to have someone agree to dig in their property to mine for the materials. You will need for people agree to do the labor of mining the stuff. you will need to people to agree to forge the material into a more useful method... All the value in a physical device is about license agreements of people will do the work for money that they will be able to trade with others.

Music isn't free to produce either. The musician has expenses that needs to be paid for, the data needs to be recorded edited produced... So a lot of people need to get paid for this as well.

You can tout that the record companies are making disproportional money... But people are paying the price, so complaining about that isn't the issue. A piece of digital data is valuable as a piece of equipment.

The real issues comes down to the fact that Supply and Demand. Digital Data can be copied exactly so cheaply that the Supply is nearly infinite, causing the actual price to go below the cost of creating it. So the companies try to put these barriers to limit supply as keep this data to be sustainable.

The key problem is most business run into their own insecurities.
They are afraid of picking the uncool system that in 5 years would be scoffed at.
Such as creating a new web app in Perl, nothing technically wrong but it isn't cool anymore.
It's the no one has gotten fired for choosing IBM. It is more about picking the name that suppose to impress your customers. Not what is best for the job.

Sure...
As we all know a Fraction where the numerator and denominator are equal is equal to one.

All fractions with a numerator of 0 is 0

So the Fraction of 0/0 is both 0 and 1. so 0 = 1 QED.

This is the reason why we can't have anything nice. Is because their are too many jerks out there who will use a new technology as a way to do illegal activities!

$50 To sell isn't really that great of an investment.

Now if these games cost $20.00 back in 1983, then you will not be making any money due to inflation.
