comment Parallel numerically integrated function can't be plotted
It seems to me that plotting in that way is going to make a lot of redundant calculations. If you want the points at x = 0.5 and x = 1, you have to integrate from 0 to 0.5, and then integrate again from 0 to 1. But really to get that second point, we only need to add on the integral from 0.5 to 1. I'd be tempted to build up some points manually and then use a ListPlot. Also, your code works fine for me (apart from the extraneous comma).

comment invert system of two parametric ODEs and plot results of do-loop
Your Do loops as written have several missing brackets and incorrect capitalisation (Nsolve instead of NSolve). What's the numerical value for zf? NSolve gives a rule as a result, not a value which you can directly compare. Maybe you want Sow and Reap rather than Print.

DayName is (still) rather slow. See here for a discussion. (Used to be called DayOfWeek before version 9).

comment Reading binary strings from file as strings
@Ajasja It's because it's simple. Easy to understand the problem and easy to understand the answer. The other question/answer is big and intimidating.

comment How to get a rule for, e.g., (x + y) to apply to (-x - y), etc.?
Use FullForm[x + y] and FullForm[-x - y] to see how those two expressions are different (or TreeForm if you are feeling daring). ReplaceAll is a dumb function that is not going to transform your expression for you. It may not be friendly, but it is reliable. In general, as Kuba has suggested, it's better to replace atomic elements.

comment calculating a sequence of functions using iteration
Actually I'm not sure how one would effectively memoise this. How do you cope with the conditions on the argument that isn't memoised?
