comment DSolve with assumptions
@2012rcampion DSolve calls functions (such as Integrate and Simplify) which do use $Assumptions. So Assuming can make a difference. See mathematica.stackexchange.com/a/65946 or mathematica.stackexchange.com/a/75243, for instance.

comment find and return the key with lowest value in association list
Welcome to Mathematica.SE! I suggest the following: 1) As you receive help, try to give it too, by answering questions in your area of expertise. 2) Read the faq! 3) When you see good questions and answers, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. Also, please remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign!

comment How can I stop Mathematica from omitting Axes on a Plot?
While this reproduces the issue described, albeit without demonstrating that the ineffectiveness of Axes -> {True, True}, it does not address the question asked by the OP. Consider adding an answer to the question or deleting your answer.

comment Unable to save a notebook as pdf
There is a slight chance this is a common problem and someone will know the fix. As the question is right now, I would think more information is needed. Even if you can't give the complete notebook, you could add which version your using and on what type OS. Have you tried copying all the cells into a brand new notebook, and then printing?

comment Coarse-graining in numerical integrations
@pepeperez You're welcome. The only thing to add was touched on by george2079. A significant difference between a finite interval {0, 8000} and an infinite on {0, Infinity} in a non-oscillatory integral is this. The finite interval is treated symmetrically by the Gauss-Kronrod rule, with more or less evenly spaced sampling. The infinite interval {0, Infinity} is transformed to {0, 1} via the substitution u = 1/(1+x); Gauss-Kronrod is applied to {0, 1}, which means the sampling is denser near the finite end point x == 0. This works well with your example, which decays rapidly.

comment Strange behaviour of suggestion bar to solve an ODE, potential bug
The argument is supposed to be a list of functions/independent variables of the ODE. Apparently it does not matter if a variable is repeated. I agree with you that it would be better if the suggestions bar gave a single instance. There is a suggestions-bar feedback button on the suggestions you can use to send an email to Wolfram Support.
