General Law of Laptop Relativity

Just thought I’d document an important recent scientific finding of mine.
Code about which somebody says “I’ve already got it running on my laptop” will, when moved to a work machine, be found to not function.
There is clearly some kind of relativistic effect going on here which is specific to the frame-of-reference of one’s own laptop.
This is the general law.
The special law of laptop relativity is that if the code was written on public transport, it will be found, from the frame of reference of the work computer that the code “could never have worked”.
