Hi Neo...
Brilliant!

Hi samthewildon...
(Apologies for typos, etc...)

I back everything Neo has said.
I am an amateur coder, I do it as a serious hobby, but when I first started coding it was on a Sinclair Spectrum using its default BASIC.
I had a Sharp MZ80K before that but its BASIC was convoluted, and initially put me off coding entirely.
However Sinclair BASIC was idiot proof, syntax errors were impossible as any line with one could not be entered directly or into a _script_.
This meant any errors were coding ones, mine and mine alone.

As an electronics engineer I decided to write a testcard program for the Spectrum, it took me a while but by trial and error I learnt things like, simple loops and decision statements. I wrote other testing snippets too for my professional work.
Well although it wasn't perfect it worked and this is what got me into hammering hardware, because drawing in the Spectrum's border was very, very limited in BASIC.
So I decided to learn Z80 assembly, I was told this was FAST, and it was a revelation. I bought a commercial assembly compiler, (by HiSoft).
It turned out that because of learning BASIC, Z80 assembly coding became second nature; and, the result being I started drawing inside the border crosshatch lines and colour bars.
This transformed my testcard and became my standard, FREE CRT alignment tool until I got my AMIGA which got me into ANSI C, a language I don't use much at all now.

I STILL code in BASIC in various platforms for quick and dirty stuff, as proof of concept for an idea.

I have coded serious stuff for the AMIGA, including an AudioScope with a full non-standard GUI which is probably my best piece of work and that was finished in 2001.
I was proficient in Python and a few other languages and all but abandoned them now in preference to UNIX shell scripting, although even after 6 years I am still only scratching at its surface as it is SOOO flexible.
When I joined in Jan 2013 I bragged about doing an AudioScope in text-mode shell scripting and it is still going on here, six years later.

SO, find something that you are interested in that requires software and start learning, words like mutable, immutable will appear in your vocabulary which I didn't know 15 years ago until I started with python. Python is a powerful language and has a library for just about EVERYTHING you need coding wise.

My pet love is coding stuff that a language was not designed to do and I have gotten the shell to do lots. I am now considering doing AudioScope in 'dash' but that might be a step too far with my POSIX compliance knowledge at present.

You do not need a maths and/or computer science doctorate, just an accepting mind and the ability to logically create code, BUT, most of all, patience and LOTS of practice.

NAME
gradm - Administration program for the grsecurity RBAC system SYNOPSIS
gradm [ -E ] [ -R ] [ -C ] [ -F ] [ -L <logfile> ] [ -O <filename|stream> ] [ -M <filename|uid> ] [ -D ] [ -P [rolename] ] [ -a <rolename> ] [ -n <rolename> ] [ -p <rolename> ] [ -u ] [ -V ] [ -h ] [ -v ] DESCRIPTION
gradm is the userspace RBAC parsing and authentication program for grsecurity grsecurity aims to be a complete security system for Linux 2.4. gradm performs several tasks for the RBAC system including authenticated via a password to the kernel and parsing rules to be passed to the kernel. OPTIONS
All options to gradm are mutually exclusive, except for -L and -O. -E Enable the RBAC system -R Reload the RBAC system (only valid while in admin mode) -C Perform a check of the RBAC policy, running the same analysis against it that is performed when enabling. -F Toggle full learning mode. If used only with -L, it enables the RBAC system in full learning mode. If used with -L and -O, it parses the full learning logs and generates a complete ruleset. -M <filename|uid> Remove an execution ban on a given uid or filename that has been put in place by the RES_CRASH resource restriction of the RBAC sys- tem. -L <logfile> Parses the learning logs. Accepts an argument which specifies the logfile to scan for the learning logs. If "-" is specified as the logfile, stdin will be used as the learning log. This option can be used with -E, -O, or -F. -O <filename|stream> Specifies output mode. Requires a single argument that can be "stdout", "stderr", or a regular file. Only used with -L or -F. -D Disable the RBAC system -P [rolename] Without an argument, it sets the password for administering the RBAC system. With a role name as an argument, it sets the password for that given special role. -a <rolename> Authenticate to a special role that requires a password. -n <rolename> Authenticate to a special role that does not require a password. -p <rolename> Authenticate through PAM to a special role. -u Removes yourself from your current special role, reverting back to the normal role selection. To be used, for instance, for logging out of an admin role without exiting your shell. -V Displays verbose policy statistics when enabling the RBAC system or checking the RBAC policy. Can only be used with -C, -E, or -F -L <filename> -h Display help information -v Print version information and exit REPORTING BUGS
Please include as much information as possible(using any available debugging options) and send bug reports for gradm or the grsecurity RBAC system to spender@grsecurity.net. AUTHOR
