Originally posted by Neo The good thing about information is that there is so much of it!!!!! And most of it is used for a particular purpose.
ACCORDING to my sources and research, the term "hack" and "hacking" relates back to the American Civil War when, when one side of the other installed telegraph wires along railroad tracks, the opposing sides would "hack" the telegraph wires to destroy communications.
In fact, the American Civil War (as I recall) was the first war to use such new fangled devices (telegraph and railroads) to support military logical operatiions.
So, there might be a lot of people who would like to define "hack" and "hacking' to be congruent with a particular cause or purpose. However, my research on the subject goes back to the Civil War in the US and the cutting of communications lines with tools like bayonets and axes

Parent Thread Of Child Thread
Suppose a process creates some threads say threadC and threadD.
Later on each of these threads create new child threads say threadC1, threadC2, threadC3 etc. So a tree of threads will get created.
Is there any way to find out the parent thread of one such... (1 Reply)
I asked my firend about hacking so he told me to come here. I want to know how to get Volumes I, II and III. Does anyone know how to help me and help me become a good hacker? This is what i came here to do!!!!!! (2 Replies)
LEARN(1) General Commands Manual LEARN(1)NAME
learn - computer aided instruction about UNIX
SYNOPSIS
learn [ -directory ] [ subject [ lesson ] ]
DESCRIPTION
Learn gives Computer Aided Instruction courses and practice in the use of UNIX, the C Shell, and the Berkeley text editors. To get started
simply type learn. If you had used learn before and left your last session without completing a subject, the program will use information
in $HOME/.learnrc to start you up in the same place you left off. Your first time through, learn will ask questions to find out what you
want to do. Some questions may be bypassed by naming a subject, and more yet by naming a lesson. You may enter the lesson as a number
that learn gave you in a previous session. If you do not know the lesson number, you may enter the lesson as a word, and learn will look
for the first lesson containing it. If the lesson is `-', learn prompts for each lesson; this is useful for debugging.
The subject's presently handled are
files
editor
vi
morefiles
macros
eqn
C
There are a few special commands. The command `bye' terminates a learn session and `where' tells you of your progress, with `where m'
telling you more. The command `again' re-displays the text of the lesson and `again lesson' lets you review lesson. There is no way for
learn to tell you the answers it expects in English, however, the command `hint' prints the last part of the lesson script used to evaluate
a response, while `hint m' prints the whole lesson script. This is useful for debugging lessons and might possibly give you an idea about
what it expects.
The -directory option allows one to exercise a script in a nonstandard place.
FILES
/usr/share/learn subtree for all dependent directories and files
/usr/tmp/pl* playpen directories
$HOME/.learnrc startup information

BUGS
The main strength of learn, that it asks the student to use the real UNIX, also makes possible baffling mistakes. It is helpful, espe-
cially for nonprogrammers, to have a UNIX initiate near at hand during the first sessions.
Occasionally lessons are incorrect, sometimes because the local version of a command operates in a non-standard way. Occasionally a lesson
script does not recognize all the different correct responses, in which case the `hint' command may be useful. Such lessons may be skipped
with the `skip' command, but it takes some sophistication to recognize the situation.
To find a lesson given as a word, learn does a simple fgrep(1) through the lessons. It is unclear whether this sort of subject indexing is
better than none.
Spawning a new shell is required for each of many user and internal functions.
The `vi' lessons are provided separately from the others. To use them see your system administrator.
