comment How can I access the internal function that plots a molecule from a formatted XYZ file?
@paw Sorry, not right away, and I'll be away from this site for a while starting today ... Try using Information or Names to see if those symbols changed context in v10.

comment Is there a built-in function which detects singularities in a function?
There must be something (possibly undocumented) because the exclusion detection feature of Plot does exactly this.

comment Font changes itself automatically during typing after == symbol
It's not really clear to me what you mean here. I do not see any font changes.

comment Hardware required to perform large symbolic calculations
Mathematica can't use the GPU for symbolic calculations. Regaring whether the standard license allows using all features: I am not knowledgeable about licenses. My university's license allows for launching up to 16 subkernels. This means that I can fully use a computer for as long as it has no more than 16 cores.

comment Calling MATLAB from Mathematica
@LeoFang Unfortunately I have very little time recently, and I couldn't even get much more important stuff get done. So realistically this is unlikely in the near future (meaning next 1 yr). But can you elaborate on it more? Do you mean the multiprecision toolbox? Also: user feedback is important in how we prioritize stuff, so thanks for commenting!

comment Cannot install prebuilt cddmathlink on mathematica
The pre-compiled Mac binary is form 2004. I think that at that time Apple still didn't start using Intel processors, so that binary will not run on 10.9 on current Macs. You will definitely need to recompile. Posting the error will definitely increase the chances of an answer. I'm sorry but currently I simply do not have the time to spend 30-60 minutes trying to figure out how to compile it, it would take me a long time too ...

Since legals topics can be particularly hard to navigate in the USA I should probably state that I am not a lawyer and have zero experience with legal topics.

A simplification of my version, GroupBy[Normal[data], PrimeQ@*First, Association]. Also, thanks for posting!

comment Path must include /TypeSystemLoader.m?
Since WB 3.0 is not yet released, you should probably report such problems to Wolfram Research directly. If it's a bug, they need to know about it so they can fix it.

comment Issue with very large lists in Mathematica
@AlexeyPopkov I didn't forget, but it was late at night and I wasn't clear enough. My point was that I see a linear increase which is exactly what one would expect.

comment Missing: KeyGroupBy?
@Mr.Wizard I wasn't going for speed at all and it's a minimal modification. Also, I'm not particularly confident in this area yet.

comment Changing BarLegend border style
I'm really glad you asked this. I needed this in the past but I never had the time and persistence to solve it. The problem is that if I really need it then I usually don't have time to find a good solution. It's a bit paradoxical, but it's sometimes easier to solve other people's problems than our own.

comment Issue with very large lists in Mathematica
I tried to test access times like this: arr = Table[RandomInteger[10, 5].x^Range[5], {1000000}]; Table[AbsoluteTiming@Do[arr[[i]], {i, Length[arr]}], {10}] I see a linear increase as arr grows. However, the very first time to iterate through the array is much slower than subsequent times.

Got the solution thanks to your hint!
