That's not true. He has already given away perhaps 6% of his total

What about % of income above the level to comfortably sustain an
individual/family? Someone earning $50k a year giving 6% is digging
deeper than someone earning $500k giving 6%, at least potentially.

if this had anything to do with Science hardware or electronics it would be
interesting. Suffice it to say that anyone who gives anything without
expecting something in return would be a great thing. However, charity, is
the furthest thing from most peoples minds, that give huge amounts of money
to anyone. Its all bout the business end of things.

How many people _have_ $1,666,666.67 to give away 6% _OF_? (which, BTW,
is probably a serious underestimate of Uncle Billy's "total lifetime
worth".)

If I have ten bucks in my pocket, and I give a street bum a buck,
am I more generous than Bill Gates, since that's 10% of my entire
wealth?

And another thing - there's a serious misunderstanding going around that
says that "size of pile of money" can in any way be related to "worth".

Just ask Nicklaus:

Without question, someone giving away 6% of personal wealth that
they could not spend in 10 lifetimes is meaningless.

If I may inject some considerations. Money itself doesn't matter
except for a feeling of security. Richness doesn't necessarily mean
greedy. Possessions are a good indicator IMO. Also, time spent doing
something matters. Spending 6% of your time helping other people is
meaningful. Whether giving 6% of your income is charitable just
depends.

If I had as much money, I might never stop shopping and
get very little done.

You are right. They get tax breaks for the big donations, but
someone who gives money or other gifts that can barely scrape by is
giving a lot more. When was the last time a billionaire given away every
cent they owned?

Its east to give away $100,000 when its just pocket change. I have
given away my last $5 to a friend who needed money to eat when I had no
job, and not enough food to feed myself the next day.

How much money does he have to give away before it meets your personal
definition of meaningful?

On whether you are hated as much as Bill Gates or not, apparently.

If you play with figures long enough, you can make Bill Gates look
stingy no matter how much money he gives away. But he is still giving
away billions of dollars, and he only has $50 billion to play with.

I'll add that frequency of opperation will depend on supply
voltage. So the difference between running on battery 2.5V
and running on AC 5.0 to 3.3V (depending on chipset) will cause
the clock to gain or loose time.

Parasitic capacitance also affects opperational frequency.
These are tightly controled in a watch, but are of little
concern in a PC.

Solution: Get a program called Dimension 4. It runs on startup,
syncs your PC clock to an internet time server, then exits. It
can work in other modes too.

I don't claim to be "noble", and I know that others have done it, but
not enough have done it. I just did what I thought was right, at that
time. I've been homeless twice in my life and I know what its like to go
days at a time without food.

Note that XP already has provisions for automatic synchronization over
the Net.
