This thread is making me wonder, Is it feasible we will someday see a USB-like device for home organic synthesis, like a 3-D printer but for products of organic chemistry?
Impossible? Waiting to happen?
The device you propose has an unlikelihood level somewhere between human immortality and teleportation.
It is perfectly legal to grow poppies. They grow very easily and is practically a weed. Since it is so easy, why would one want to use yeast?
No, it's not perfectly legal (in the US) and may be perfectly illegal in other jurisdictions. That said, they grow like weeds in the part of Canada where I live - and they are the very first item in our criminal code's list of illegal substances
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:-)
Actually it was pretty hard to get them to beat each other's prices. I'd generally have to make an embarassment of myself to make it happen. The mangers always argued that since they are the same company, they couldn't beat their "own price."
This is an improvement. Cluelss people would compare prices between those two retailers assuming they were competitors in order to assess whether a price was good.
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.
I find it much more probable that life begins in milder, friendlier conditions and then adapts over time to harsher environments. Of course, everything is relative.
Ah, but mild and friendly is a relative term. I'm not sure our frame of reference is a valid example of mild and friendly...

Except those wiretaps were lawfully obtained with a search warrant approved by a judge.
Better watch more closely - or watch the whole thing :-)
Reminds me of a Baltimore TV show. Now, what was it called?
n/t
It also works if your name happens to be Elon.

Could you provide a reference that's not narconon (a division of scientology)?

Study chemistry. Chemists really know how to unionize.
The joke is funny but the truth around the chemistry job market isn't so funny. It's as subject to offshoring as anything else.

My job's main function is to remove pee from water. It's not that hard.
So you're a kidney?
I guess you weren't looking for > 50% price reductions like I was :-)

Oxygen, Hydrogen, Nitrogen and Potassium.
Compounds containing these elements, or pure (elemental) forms of the elements? What happens to the phosphorous, alchemically transmuted?
What sound does a "platinum bomb" make? Pt
Accidentally modded this down, replying to erase the damage and point it it's a funny comment!

I accidentally mis-modded this so posting to remove the moderation and compliment you on your funny and insightful solution :-)
2^32 - 1 = 4,294,967,296 2,147,483,647 = 2^31 -1 ...so either they were using a 31-bit integer or they were using signed ints.
How exactly does one get a negative number of views?
2^32 - 1 != 4,294,967,296
