Technomantic LS
The value of technomancy for me has been when applying the Principle of Correspondence.
If science has shown a thing to exist or happen on the material plane, it is safe to say it can be used in the other planes with some amount of effectiveness.
Encyclopedias of information on the archetypes of gravity, strong force, weak force and electromagnetism are available for for the price of an internet connection.
I could dent this server's storage space with information on how to use these forces for magic/technomancy. When these four forces are used in conjunction with the four states of energy (fire, air, water, earth) surrounding the mediator (consciousness, which is a primal state and a force) interesting things can be imagined. If interesting things can be imagined...
In my professional life I'm a hacker who's been raised up to Senior Software Engineer because I have an almost-supernatural ability to find leverage points in complex systems. The most valuable tool in that aspect of my life has been the ability to read and write code in many different programming languages.
In my magical life the most valuable tool I've found is the esoteric programming language. One can program their woo by simply thinking at it. That approach kinda worked for me but wasn't satisfying and it left lots of room for disbelief (and outside influences) to creep in.
I've defined a lot of sigils using what we could call pseudo-code with varying amounts of success. If an off-the-cuff code language can work then a more rigidly defined system should probably work better. That is the reality I've found. (Perhaps this just helps me suspend disbelief...)
I've since created my own using the forces as operators and elemental states for flow control. The details of which I can get into in another thread if anybody has interest.
You don't have to develop your own; it is possible to program your woo with Javascript. It is effective to create a JS model of the effect you desire, print it out, burn it and stuff the ashes in a mojo bag or cup of wine (destroying the source files leads to more immediate, yet chaotic results while storing them on a sacred flash drive leads to longer-term, subtle and stable results).
Any language works but most don't lend themselves to astral use unless you're the guru of gurus. Additionally most languages have conventions that are necessary and/or helpful on the material plane but are just baggage on the astral or don't work at all.
For example, defining scope in Javascript is complex but works well when your code has to fit into a text file and be quickly parsed and control aspects of a browser window or its contents.
Defining scope in an esoteric programming language could be as easy as imagining or drawing a fucking box around something. But perhaps that's just a personal preference.
I think a DKMU specific esoteric language would be the first step.
