... So you make the directory unreadable, by literally setting the permissions to not allow it to be read, and somehow suggest that it is still readable?

As an example, if something happens once every thirty years, but you have only been alive for twenty-nine years, would you conclude that the even happens rarely or never?

Similarly, if you have never been to a trade show, does that mean you will never be able to go to a trade show?

True... the phrase I was searching for was 'protocol overhead'. I did a quick google and found the following:

Since we are talking ethernet, here are the numbers:
Ethernet: 1500/(38+1500) = 97.5293 %
TCP: (1500-52)/(38+1500) = 94.1482 %

You are correct about the lmgtfy link, that was supposed to be a google.com/search?q=hellban link instead. Must have been a brainfart or typo or something. Can you imagine how embarrased I must be?

This technique is widely used against trolls on various Internet forums. It is often called 'Hellbanning'

1 Terabit a second on the wire translates to about 100 Gigabytes a second of actual data transfer. Most modern encoding schemes and encapsulation protocols average 10 bits to represent an octet.

EVERYBODY has a bad teacher at some point.

Besides, teachers are not the only ones who can turn mediocre students into bad ones. Bad parents, bad peers, bad genes, bad environment, bad societies...

You give the teachers too much credit.

It's okay, I have tcpdump.

Or, It's okay, I have coaxial network cable, a multimeter and a quick eye.

The 'imperial system' isn't in place. You use 'United States customary units.

Re: your sig:

Does that mean that quantum field theory is the luminiferous aether of modern particle physics?

More than than, a plain sheet of paper placed in the sun is brighter than a candle.

The source of their depression is neurotransmitters. Are you advocating a chemical solution?

Dude, the game is called 'MineCraft'. You can mine. You can craft. What exactly is missing?

Yes, that is correct. You should write your apps in Python.

Your libraries, you should write in Python first, because it is also a great prototyping language. If they work fine (which they will in most cases) you have saved yourself a bunch of time. If they are too slow, you have saved yourself a bunch of time by fixing algorithmic bugs in a flexible language like Python. It is now trivial to convert it to bug-free C or C++.
