Sensitivity is a factor but selectivity is much more crucial to any such analysis. Without physically separating the constituent materials as part of an analysis, "signatures" will overlap and obscure each other. Anyhow, I'm not pooh-poohing this technology, just trying to add some balance to the conversation, which (around here) trends towards science fiction more than science.

The problem is that the spectroscopic techniques capable amenable to implemention on a small device can only give some general information about a material or mixture. This may be enough to select one option from a narrow set of possibilities (eg: is that drain pipe PVC or ABS plastic?). However, it is not going to identify the presence of a toxin in a bowl of soup or tell you that your gold watch is only gold-plated.

Without reading TFA I can assert that this area of work is not going to let the consumer unambiguously determine the composition of anything. Right now the chemical analytical techniques to figure out what the composition of a substance require huge machines and significant training in spectroscopy and there's no way of miniaturizing those techniques and automating the interpretation of the data. I'm sure you can get some information but not enough to say anything for-sure :-)

Rape is infuriatingly common in our world, while reporting and/or prosecution for the offense are comparitively rare. So, this probably isn't the first time this has happened. For the survivor's sake and for the sake of setting a precedent (Uber must find a way to stop this from happening), I hope the lawsuit is successful.

How about compiler being able to leverage Cuda hardware if found during execution? Might make for fatter binaries, but..... if it found GPU, it might help in some cases?

Well, the system of execution is often different from the system of compilation. So, you'd want to have the compiler-user specify that a CUDA-specific binary should be compiled alongside (afaik cuda/x86 fat binaries aren't a thing right now). And that falls into the realm of build system, not compiler. From what I've seen the build system (make in this case) relies on nvidia's compiler to builld the cuda libraries subsequent linking into the cuda executable along with the c* and fortran code.
