I'm interested in data visualization, image processing, ODE/PDE, natural language processing, etc.

I'm currently a freelancer of Mathematica programming / Mandarin teaching / logo design.

comment Is this 30% slowdown in Mathematica 10 due to DownValues lookup time?
v10 vs v9.0.1 (both on Win8.1-64): {{1.87234,1.51456,1.250000},{1.282051,1.417234,1.354227},{1.389864,1.407700,1.0‌​161082}}.

comment Does Dataset round?
As it's your post, if you feel like to edit, it will be more accurate than I editing. Regarding to your worry, I suggest having a look at what the developer of Dataset said under the linked dup-question.

comment How can I use “Save as (html)” and still render code as text?
@HyperGroups Looks like the is interpreted by mma as \[RightArrow], try using -> (\[Rule]) instead.

comment Does Dataset round?
It seems you have got your answer:) FWIW I have reproduced the bug with Dataset[{<|"a" -> 380160.|>}], so do you agree we can rephrase the question to excluding the Excel part?

Well you can't have a coordsys matching for all of them :) (or can we?)

comment How to define logical expressions for platonic solids?
+1 for demonstrating the new features in v10. But I guess what OP wants are some mathematical insight, beautiful in concept representations. I'm thinking about something starting from the crystallographic point groups, but I've forgotten my group theory knowledge.. :(

comment How to define logical expressions for platonic solids?
@hieron OK the microscope thing reminds me, maybe there are simple 3D cellular automata rules generating these polyhedrons. But I think the formulae provided by PolyhedronData[..., "RegionFunction"] are not optimized for insightful concept but for numerical computing. If you are looking for the former one, you might want to emphasize it in you question.

You can make it shorter with ContourPlot3D[Norm[{x,y,z},1]==1,{x,-1,1},{y,-1,1},{z,-1,1}].

@hieron So maybe they are not so regular in the universe :)

Could you give a sample xlsx file? In case people want to try but don't have an MS Office.

@Lawerance Regarding the formatting, "Markdown" is the name/keyword you would like to feed to search engine.

comment Grid - sizing and spacing problems with spanning cells
@Mr.Wizard No I haven't. But in that case I would try another approach, maybe an Overlay in which a Graphics align with a text Grid. There must be some (undocumented) functions who can measure the size of boxes or line-height in the FE.

comment Grid - sizing and spacing problems with spanning cells
@Mr.Wizard Thanks. I have tested some ImageSize from 1 to 200, it looks like when it's less than 6, this trick will suffer from this problem. Except that, I believe it'll work fine.

comment Programmatic formatting for Mathematica code - possible?
@LeonidShifrin Sorry somehow I didn't get the message pin.. I'm really excited for even just thinking about an FE-based IDE! And I'm very much interested in testing it! :D If there is anything I can contribute it will be my pleasure. Regarding the formatter, I will closely read your code on github. Thanks for the detailed response :)
