You're talking about applying force to counter existing forces (i.e. inertia, frictional co-efficients, lack of banana peels, etc.)
Gravity is attracting constantly all the time, making it one of the forces that you're countering by introducing vectors, so sure, if you apply more force per kilo to counter all the other forces, you'll improve the vector, but a car can only accelerate as fast as its engine can turn the wheels.
A car that weighs less will (within reason) accelerate quicker because there is less mass to move in a vector across the other forces.
Change the value of G, and the amount of force required to counter it also reduces, but again, you can only change the value of G theoretically (e.g by writing different numbers on paper), so it's another one-way equation, like the hammer/feather one.
I wanna be a eunuchs developer! Pass me a bread knife!
Firstly, mass has a gravitational effect.
It bends space time, so the more mass something has, the more it bends.
From this is can extrapolated that the hammer hits the ground before the feather.
Basic physics my friend.
It is just a shame they do not actually teach this, and merely spout the same crapola about them landing at the same time.
If a hammer is dropped from 10 metres and the time to impact is recorded, and the feather is dropped from 10 metres and the time recorded they will appear to be the same.
This is because the mass differential between the hammer and the feather is so slight as to be negligible.
No-one believe me?
Here is a mind experiment.
The hammer and the feather are both at 10 metres above the ground.
HOWEVER, they are at opposite sides of the moon.
Now the moon will pull upon them both, causing them to fall.
And this is where it becomes obvious...
The hammer has a mass that is pulling the moon, ever so slightly, toward it.
The feather has a mass that is pulling the moon too, but as the mass of the hammer is greater, the moon will move toward it.
This means that the hammer has less distance to fall, and the feather more.
Therefore, if dropped at the same time, the hammer hits first.

"This project was a typical e-commerce site with one significance difference: the site hosted multiple stores (under a single domain), with a similar look and feel for each. The stores were managed individually, but offered products for sale through a common shopping cart."
"The original quote my new client had recieved from their vendor was a measly $10,000 (a website of this magnitude typically costs in the range of $75-100K). When all was said and done, the final cost jumped to over $25,000."
Is this correct? $75 - 100K for this? What would you charge?
Any intelligent fool can make things bigger and more complex... It takes a touch of genius - and a lot of courage to move in the opposite direction.

Oh bliss! Bliss and heaven! Oh, it was gorgeousness and gorgeousity made flesh. It was like a bird of rarest-spun heaven metal or like silvery wine flowing in a spaceship, gravity all nonsense now. As I slooshied, I knew such lovely pictures!
