来自主题: Tennis版 - Get More Depth
If you want to stay in control of the point, you've got to get good depth on
your shots.
By Debbie Graham
From the August 2003 issue of TENNIS Magazine
So there I am, running side to side, up and back, trying to chase down a
tennis ball that's controlling me. I feel like a puppet on strings manipulated
by the hands of my opponent. The harder I try to turn the point around, the
shorter my balls land and the more my opponent runs me all over the court.
Help!!
The solution seems obvious, but in th

Here is my take.
your definition of moon baller is mainly block high and push the ball right?
Some with some topspin, but it's not those high and heavy balls (Rafa)...
Their strokes racquet has more open face, it makes "more" contact with the
ball thus they get more of a response, or more consistent response.
Therefore they get more feel, and grasp the this control faster. They also
pay more attention to this because their game style.
You probably hit with more spin and pace. For spin, it's more... 阅读全帖

You are right. That is my style.
I hit top spin BH, FH on almost every shot. When I hit harder, I create
more pace and along with more top spin. Due to additional top spin, my
harder shot does not go that much deeper. I think most of my rally balls
land around service line. Even it has good pace, due to lack of depth, it
does not hurt my opponent that much.
I want to change my average rally ball to land in the middle of base line
and service line. I hit with a teaching pro for couple poin... 阅读全帖

Yes, that took away my top spin, which is my control.
Now, I feel the height control is the key to control Depth. Focusing on hit
4-5 feet over the net with good top spin. I want to be top spin
moonballers. lol
But how to learn to control the height in order for me the keep my shots
deep?

feet over the net!

First of all, it gives me tons of UE since it easily goes into the net.

Hitting the Wall
I like to use Kids red or orange ball. It slows thing down. Allow you to
hit though the ball with limited space.
It is productive, you don't need to pick up tons of balls.
It is great for preparation, foot work, timing.
Downside
But I don't see the depth of the short.
Hard to work on CC shots.

So, we got shuffled past a 3DS at a rapid pace this morning on our way
out of the Nintendo keynote, but we've just had an opportunity to play
some titles and really get a feel for the thing... and we're pretty
impressed. Before we were only shown a technical demo, but at Nintendo's

来自主题: PhotoGear版 - Depth of field (in macro photography)
I have heard people talking about shallow depth of field when doing macro or
close up photography. Here I tried to get an idea of exact how shallow it
is. I stacked some pennies into 5 stacks.
As you can see from the picture, the five stacks had 1, 2, 3, 4, and 5
pennies respectively. The stack of 3 pennies was in the center.
Then I used a 50mm lens with the Nikon 4T close-up lens attached. I set the
aperture of the lense at f/2 and focused on the central stack. Here is the
result

我的输出是
[["hit","hot","dot","dog","cog"],["hit","hot","lot","log","cog"],["hot","dot

测试数据输出的是

Given a nested list of integers, returns the sum of all integers in the list
weighted by their depth. For example, given the list {{1,1},2,{1,1}} the
function should return 10 (four 1's at depth 2, one *2 at depth 1). Given
the list {1,{4,{6}}} the function should return 27 (one 1 at depth 1, one 4
at depth 2, and *one 6 at depth 3)

part of our 16th President’s head is always hidden by the tread, you have
more than 2/32" of tread depth remaining.
