I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. My main reason for joining StackExchange is to participate in Mathematica.SE. I enjoy answering question when I can, but I also enjoy working at making the site a better place to visit.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 10.0.2. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

comment NotebookWrite in EvaluationBox forces Input CellStyle
I don't see how this can be fixed by a work around. EvaluationBox is going to create a cell no matter what, and you don't want a cell. If you did, sacratus' answer would serve you. But because you want a box structure to insert into a possibly much larger expression, I think EvaluationBox is simply inappropriate for the purpose you have in mind. Therefore, I would not call what you have encountered a bug.

comment Ordered associations
@denfromufa. I can't guarantee any behavior, but all the ways I know of that can delete a pair preserve the order. Obviously some operations, such as Sort, KeySort, etc., don't preserve order because their purpose is to change it. I would recommend that you just try any operation you are suspicious of and see what happens. Mathematica is so interactive that is trivial to make such experiments.

Kuba, I have edited "walkaround" in your posts to "work around" several times in the past, but I think you should make the edit this time to help you learn the correct English idiom.

comment How can I simplify a triple integral with exponentials?
You say you made the assumption that p > 0 && q > 0, but such an assumption doesn't appear in your code.

comment If the earth's rotational speed increased by 2% each day starting today…what would be the difference in age 20 years from now?
@2012rcampion. No, it's more a physics problem. The answer would be no one would of any age because nobody would survive such a change of rotational speed. I suspect the planet itself would disintegrate.

comment How to iterate through a list of rules?
Your question implies that some or all the keys and values in your list are strings, but in your post they all look like symbols or rational numbers. Please reformat your example to make the strings explicit.
