Turning all hardware problems into software problems?
And it has taken him ten years?
I could have solved that problem in 10 seconds.
Bingo, all your hardware that used to work under Windows will now have
software problems under Linux....
Now, wasn't that easy??????
I didn't think that you were so stupid, so I guess that I have to
explain the problem using words that even a child could understand.
These days there are more people wanting to use radio then there are
frequencies with reasonable coverage to accommodate them.
This is forcing governments to insist that new technologies be developed
to allow communications that uses less of the available frequencies per
Achieving this is a very complex problem.
The more complex a problem is the more complex the solution is likely to be.
Complex solutions often have errors.
Errors in hardware is often quite expensive to fix.
Errors in software generally only require a software update and are as
such much cheaper to carry out.
If all the complex signal processing done in hardware were to be done in
software, then it would be easier to fix any errors.
This is a very complex problem.
Linux is a good fit for this sort of a problem, because it allows the
world to work together to come up with a solution.
