Not for lack of trying. I do understand scripts in various scripting languages well enough to debug them, to adjust them to my needs and to expand them if necessary. But I could not write one on my own if my life depends on it. Does this make me dumb?
No it doesn't make you dumb, it means you have not found your niche to create an "_app'_" to take on and maybe even excel at compared to your peers.
It also means that you probably have much more activity in other fields in your private life which would make you think a lot.
I found mine in the late 90s:
My programming niche...
This started me on the road to my multi language learning.
I hadn't ever seen a shell script until joining this site in January 2013 so I jumped in at the deep end bragging with an AudioScope.sh, a SINGLE "bash" script which has, and is, still being gently followed.
I deliberately placed limits on it and the biggest one was the I/O. ONLY the mic and ear are allowed for input and output. USB, Parallel, Serial and others are NOT allowed.
These had to deliver DC as well as AC components on input and output. I got a tremendous amount of help from the big guns on here and from these beginnings I have done some really strange things and most are POSIX compliant:
A DFT in a PURE ksh93 shell script.
A GOTO function.
A Fixed Point SQRT using integer maths.
And much more, all on this site. Most have been bettered by my peers who still know much more than I do about UNIX scripting.
Why?
As a pure learning task to see if it is possible and nothing more.
I am working on a POSIX compliant DFT using integer arithmetic ATM and it is seriously tough. I don't expect it to work but I do have a natural ability to think laterally/orthogonally hence my bizarre uploads to this site.
So GO FOR IT, even if it is something like a CrossStitch Program or calculating the minimum area for a _mains_ cable carrying large current loads.
You would be surprised what you learn by taking on such a task.

liquidsoap
LIQUIDSOAP(1) General Commands Manual LIQUIDSOAP(1)
NAME
liquidsoap - a multimedia streaming language
SYNOPSIS
liquidsoap [options] [script|expression]
DESCRIPTION
Liquidsoap is a programming language for describing multimedia streaming systems. It is very flexible, making simple things simple but
giving a lot of control for advanced uses. Liquidsoap supports audio, video and MIDI streams, and a wide range of input/output operators
including Icecast and various soundcard APIs. It can perform a broad range of signal processing, combine streams in various ways, support
custom transitions, generate sound procedurally... and all this can be assembled as you wish. Input files can be accessed remotely, or
even be synthesized on the fly using external scripts such as speech synthesis. Finally, interaction with a running liquidsoap instance is
possible via telnet or socket.
Liquidsoap scripts passed on the command line will be evaluated: they shall be used to define the streaming system to be ran. It is possi-
ble to pass multiple scripts; they will all be ran successively, and definitions from one script can be used in subsequent ones. A script
will be read from standard input if - is given as script filename. Information about scripting liquidsoap is available on our website:
http://savonet.sf.net/
If the parameter is not a file it will be treated as an expression which will be executed. It is a convenient way to test simple one-line
scripts. When running only one-liners, the default is to log messages directly on stdout rather than to a file.
OPTIONS
-
Read script from standard input.
-- Stop parsing the command-line and pass subsequent items to the script.
--debug
Print debugging log messages.
--dynamic-plugins-dir path
Directory where to look for plugins.
--errors-as-warnings
Issue warnings instead of fatal errors for unused variables and ignored expressions. If you are not sure about it, it is better to
not use it.
--interactive
Start an interactive interpreter.
--list-plugins
List all plugins (builtin scripting values, supported formats and protocols).
--list-plugins-xml
List all plugins (builtin scripting values, supported formats and protocols), output as XML.

--version
Display liquidsoap's version.
-c, --check
Check and evaluate scripts but do not perform any streaming.
-cl, --check-lib
Like --check but treats all scripts and expressions as libraries, so that unused toplevel variables are not reported.
-d, --daemon
Run in daemon mode.
-f, --force-start
For advanced dynamic uses: force liquidsoap to start even when no active source is initially defined.
-h plugin
Print the description of a plugin, eg. a builtin scripting function.
-i Display infered types.
-p, --parse-only
Parse scripts but do not type-check and run them.
-q, --quiet
Do not print log messages on standard output.
