comment Where's the service status page for Programming Cloud?
It seems that you might have accidentally created a second user account. You can request a merge as described in the site FAQ.

comment Generate cyclic list from a list
@rcollyer Your form is superior because the first element of PadRight needs to be packed if possible, and {} is not packable. See this for example.

comment Generating a matrix using sublists A and B n times
@Guess I found a good reason for my answer to exist and updated my post. Hopefully it sits better with you know. (It does for me.)

comment How to imitate list comprehensions for constant arrays?
@Karsten PadRight is much faster than ConstantArray when used well. "Periodic" looks nice but slows down PadRight, but still not so much as to be as slow as ConstantArray. I'll add timings to this post.

comment Systemic bugs in GraphPlot and related functions such as TreePlot and TreeForm
@Stefan I'm sure that even before v6 other methods were standard. I found a number of cases that still do not use OptionValue but simply join the lists, i.e. "OptionName" /. Join[ Flatten[{opts}], hiddenOptions[caller] ]. I think so long as each element in Join is assured of being a List and not $Failed or whatever this should be robust, right?

comment Confusion over blank sequence in pattern matching
@JackLaVigne Glad I could help! By the way beware of (1699) -- the precedence of the ? operator is highly unusual. (For more about operator precedence perhaps read (30425).)

comment Checking the argument of user-defined function with side-effect method
Sorry for still not posting anything new. I've been feeling a bit burned out recently and I am not spending as much time on the site, so my participation is mostly quick answers to simple questions and basic site maintenance. Your question proved more difficult. As stated you seem to have figured out side-effect messaging quite well, and I found that I did not have an answer for the Problem with D and PiecewiseExpand. I hope that in the future I will (continue?) to be more helpful to you.

comment Mathematica file transforms to some strange format
When this problem occurs do you know right away or only when you reload the Notebook? I mean does the content of the Notebook, still open, suddenly change when you get a "bad" save?

comment Mathematica file transforms to some strange format
" if I try to modify that file." -- just to be sure, you're not editing these Notebook files outside of Mathematica, or opening the same Notebook in two different Mathematica sessions, are you?
