comment Which TCP congestion control algorithm is best for low speed radio modems?
That's what I mean about measurement of real networks: 25% packet loss is dreadfully underspecified and would need dispersion, burstiness, and so on to properly characterize. I maintain my guess about standard TCP being hard to beat for your capacity and mean loss rate.

comment Can TCP provide more than 65535 ports?
@Bryan I can't help but think the WhatsApp example you cite is akin to me claiming "I can encode real numbers up to about 1.8 * 10^308 in a 64-bit IEEE754 double". That statement isn't strictly false, but what is unstated is at least as important as that which is.

comment Difference between “.” and “./” while setting the environment variables using export?
Your use of the terminology is fine. Your error is in not understanding what the almost invisibly named shell built-in command . is for. The references that @devnull listed will enlighten you.

comment Can TCP provide more than 65535 ports?
While there is nothing that formally restricts you from wearing 65 pairs of trousers at once, it would be practical idiocy to try. If you can show me a machine that can fruitfully process 10'000 TCP ports concurrently, then this might be an interesting abstract question.

comment Error when constructing an associative array
If you are trying to program a game in bash for the sake of making things hard on yourself, rock on. If you are just trying to program a game, bash is a very poor choice of language for the task.

comment Increase brightness in a part of the display
If there was, it probably wouldn't yield satisfactory results. Either the illumination source is damaged or the lcd is, and will not be able to produce the same luminance or contrast as the undamaged part regardless of how you change the contents of the framebuffer.

comment Why can't I execute shutdown when the permission is rwxr-xr-x?
You won't see that in the strace output since it only reports system calls. You can infer that when a getuid is closely followed by writing the error message that the code was similar to if(getuid() != 0) printf("Need to be root");. Which in fact the source code shows it to be.
