I was just wondering why people tend to use a base 10 number system. I
can't help but wonder if it is due to us having ten fingers. Anyone
have any insight into this?
It is definitely due to having 10 fingers.
The reason for base-2 with computers is that it is easier to build an
electronic circuit that is stable in two states rather than in a larger
number of states.
The original reason for base-2 in computers was that this was simply an
electric circuit either being on or off.
See Logic gates http://www.kpsec.freeuk.com/gates.htm#not
It's a bit more complicated than that, as some very early computers did
indeed compute using either binary-coded-decimal or analog. The former,
of course, parcels out 4 bits, wasting 6 states; the latter is wiring up
a circuit using various components to model/solve a problem and read the
result using a volt or ammeter.
The results of very early BCD computers might have been displayed using
Nixie tubes. There are also issues such as 1's complement versus 2's
complement and it took a long time for the notion of a computer as a
digital control system (where each bit represents a device to be
switched on and off -- e.g., lights in one's house, traffic signals) as
opposed to either an "electronic brain" or calculating device to catch
on for some reason.

There is nothing there!
That appears to be temporary; I'm having no problems pulling it up here.
When I said there was nothing there, this is what appears when I point to:
"Wikipedia does not have an article with this exact name. Please search for Flip-flop (electronics in Wikipedia to check for alternative titles or spellings.
Start the Flip-flop (electronics article or add a request for it.
Search for "Flip-flop (electronics" in existing articles.
Look for "Flip-flop (electronics" in Wiktionary, our sister dictionary project.
Look for "Flip-flop (electronics" in the Wikimedia Commons, our repository for free images, music, sound, and video.
Look for other pages within Wikipedia that link to this title.
If a page was recently created here, it may not yet be visible because of a delay in updating the database; wait a few minutes and try the purge function. If a page previously existed at this exact title, check the deletion log and see Why was my page deleted?."
Ah. I think I see your problem; you're confusing ' ' with '_'
apparently. Admittedly, it *is* possible that Wiki is a clustered
solution but frankly I don't know what the difficulty is in that case.
You could try the escaped form:
http://en.wikipedia.org/wiki/Flip%2Dflop%5F%28electronics%29
Going by the generated error text, the actual problem was that the closing parenthesis was not included in the link by the newsreader.
Spaces in Wikipedia links are equivalent to underscores (and the article title displays without the underscores), so there should be no problems in that respect.
