comment Is this 30% slowdown in Mathematica 10 due to DownValues lookup time?
The other day I benchmarked RUBI in v8, v9 and v10. v10 is only marginally slower (< 2% difference). RUBI uses huge sets of (DownValue) transformation rules. I don't know if this is relevant to your question or not.

comment Ideas for introduction to Mathematica on Raspberry Pi
I think this is a very interesting discussion topic, but StackExchange is not meant for discussions ... so this is borderline off-topic. Perhaps you could post on community.wolfram.com which encourages discussion? If you do, do let us know here, so interested people will know where to look. (I'd be interested.)

comment Assign a randomly generated list to variable
You could also edit the question and where it says "Introduced in 10.0.0" add "and fixed in 10.0.2". That way it's immediately clear that we don't need to worry about the bug, without having to glance through all the answers.

comment Graphic solution lagrange multiplier (cant get one)
"Sorry for my bad english" <-- You can start by trying to use proper capitalization ("I" vs "i") and including some punctuation. Yes, these things really make a difference in how easy it is to understand your question.

comment Setting up tunnel to access compute nodes behind private LAN via front-end
Finally found it: stackoverflow.com/q/6226196/695132 Take a look at the comments for a newer version of the same (by 'sakra'). I don't use this myself anymore so can't give much advice ... the reason is that I found remote connections to be extremely unreliable when I was using Windows XP (freezing front end), so I gave up. I remember others told me they couldn't reproduce the problems I saw on more modern systems, so you shouldn't give up on OS X because of this.

comment Adjusting size and positioning of math notation in a Mathematica notebook?
Perhaps the best way would be a to create a "Display math" style with these options set and put these equations in their own cell (of this type)?

comment Prevent axis label being cutoff
Could you mention the version of your Mathematica and your operating system, so we can properly tag the question? I am unable to reproduce the problem on OS X, either in M9 or M10. Based on your and kguler's screenshots, is it M9 on Windows?

comment Prevent axis label being cutoff
Can you give a minimal example that illustrates the problem, mention your Mathematica version and your operating system? I have never seen this problem, so I assume that it only happens under special conditions. Let's find out what those conditions are. Also, since you signed the question, could you set an easier to remember name in your profile than "user2003951"?

comment Any Progress with a Python MathLink?
You could always suggest it to support at wolfram.com. I guess the more users ask for it, the more likely we'll get it. You might mention that MATLAB received some deep Python integration in its latest release (R2014b).

comment Is it possible to get a symbolic expression from FindRoot?
(I assumed you know about the symbolic solvers such as Solve, Reduce, etc.)

comment Is it possible to get a symbolic expression from FindRoot?
No, it is not possible. FindRoot is a numerical solver. It uses methods such as Newton's method. You can, however, write a function that will compute the solution of the equation as a function of y.

Though Variables[x^a] is {x^a}, not {x,a}.

comment Infinite sums with Boole and EvenQ
"Since Q functions always return True or False" --> I never realized this. Is there no exception? Is that the reason why Positive is not called PositiveQ?

comment How to replace all symbols except several?
But I'm not very happy about this solution. For example, Pi is a symbol too and you probably wouldn't want to replace it ... I'd rather make a list of all relevant symbols first and work with that. Just to make sure nothing is included that shouldn't be ...
