RealVNC is (I think) the original. I’m guessing that the others are forks of Real, and that either Echo is a fork of Ultra or Ultra a fork of Echo. Tight seems to be a fork of an earlier, simpler version of RealVNC. And, according to their website, is “fully compatible with the standard RFB protocol used in VNC.”
It’s not surprising then that, out of the box, TightVNC is the only client I could get to connect to a Mac from my Vista machine at home. Tight’s refresh/rendering is plenty slow, but gets the job done.
As you can see, in less than five days the Epoch time will reach 1234567890. Ephoch time is, of course, POSIX time, a popular time-keeping method for Unix which is measured in the number of seconds that have passed since the POSIX clock started virtually ticking at midnight on January 1, 1970 (not including leap seconds).
I hereby call on all geeks everywhere to begin immediate global Epoch time party mobilization. We’re gonna party like it’s 915148800!!
Or, well technically we’re going to party like it’s 915148800 + 319419090 plus or minus some leap seconds. Which happens to also be this coming Friday the thirteenth. Which might be unlucky except that it falls before Valentine’s day in the year of the Bull, so…
Er.. Nevermind, just get some booze and spread the word.
