"Exploring a C program's memory use over time, on Linux" would be more accurate. Nothing in this article deals with our three spatial dimensions, the typical use of the word "space".
> you should consider explicating that space = memory, time = time.
That seems unnecessary. Even a layman knows that in the context of a computer, space != physical space. Most people think of disk space, but it can also refer to memory usage [0].
The meaning of the name was obvious to me after reading the first half of the first sentence of the article. I thought it was clever :)
FWIW, all these things date back to the ancient Usenet "RTFM" (where M = manual) which would undermine an expansion of "featured" in my view (since manuals are not "featured", like links in news aggregators). The other alternative Fs still work, though.
