In my journal I discovered a bunch of orange warnings of the form “at24 0-005…: supply vcc not found, using dummy regulator”:

First, I asked myself what I am being warned about, and it took me quite some time to find out what “vcc” means. Is actually “Vcc”, the voltage common collector as on http://upload.wikimedia.org/wikipedia/commons/4/4b/Voltage_subscripts.png , meant (where “cc” or “CC” is sometimes typeset as a subscript)? If so, write this way, i.e., “Vcc” (or, as a proper abbreviation, “VCC”). The term “vcc” in small letters means to me, for example, the command-line call of the verifying C compiler; to other folks “vcc” might mean something else. If “vcc” here is NOT the voltage common collector, consider writing the full term instead of the abbreviation. (Similar goes for “spd”: if it's a proper abbreviation and not a typo, consider capitalizing all the letters. Further, even “SPD“ might mean many things, from “Serial Presence Detect” to “Surge Protection Device”, so if the context doesn't make it clear, write the full term instead of the abbreviation.)
Second, are these orange messages real warnings (i.e., they foretell potential havoc) or only informational? In the real case, what could go wrong? In the purely informational case, consider making them normal gray-white messages, so that the user is nor really feeling warned or bothered.
Gratefully, AlMa
