Hello
The biggest difficulty in mobile client software development is that the platform is not uniform and there are too many mobile development platforms. Mobile phones can be divided into smartphone development and featherphone. Development platforms can be divided into open platforms and closed platforms. Open platforms include Symbian, windowsmobile, Linux, iPhone, Android, BlackBerry, j2_rw, and brew. Mobile apps are supported.ProgramDownload and install through OTA; closed platforms include MT

chopper, just send a POST request with a file write command to the URL containing a sentence on the remote service, for example:
POST:
1= @eval ($_post[z0]); z0=echo $_server[' document_root '];
The above code contains 2 parts:
1. The password of a sentence
2. PHP execution code sent to server side
Now that we know the principle, we just need to send the following POST request to complete the function of uploading a file using a sentence:

I. Basis of four tuples
Q (x, y, z, W), where X, Y, Z is used to determine the rotation axis, W is the Rotation Angle
Q = W + Xi + YJ + ZK, I, j, and K are the unit components of the three virtual axes.
I * j = K
J * k = I;
K * I = J;
Cross multiplication:
C = A × B =
| I j k || A1 B1 C1 || A2 B2 C2 |= (B1c2-b2c1, c1a2-a1c2, a1b2-a2b1)
C is also a vector, and the length of C is | A | B | sin (theta), perpendicular to the plane where A and B are located. The direction is determined by the right h
parallel lines on the X and Y axes.) You can analyze the connection conditions and see that there are three possible conditions.
1: Linear connection 2: One Fold Point 3: two fold points. It can be found that if there is a discount point, each discount point must have at least one coordinate (x or y) that is the same as one of the target points, that is, the discount point must be in the x or y direction of the two target points.
The design logic is as follows:
Assume that the target point p1 a

) Analysis: First we need to know what is fixed noiseFixed noise is caused by the fact that the target function f itself is too large for QF. If the QF of F itself is too large, then it is not easy to use H to fit this higher objective function, so the fixed noise is large. When we use the smaller h ' instead of H to fit F, because H ' is smaller, the fitting degree of f is even worse, so the deterministic noise will increase!(3) Answer: Increasing second item2.

Determine whether the vertex is on the online segment:
If the vertex is set to Q and the line segment is P1P2, the basis for determining the vertex Q on this line segment is: (q-P1) × (P2-P1) = 0 and Q is in P1, p2 is inside the rectangle of the diagonal vertex. The former ensures that the qpoint is on the P1P2 line, and the latter ensures that the qpoint is not on the extended or reverse extended line of the P1P2 line. The following process can be used to determine this step:

The Z1 screen, due to the use of a variety of troughs TFT panel, enables Sony to spend eight hundred of the cost on Z2 a serious IPS screen, and the screen brightness has reached 450 nits + international version, the entire screen looks pretty cute. Z3 is the screen brightness even further, so that the maximum screen brightness of 5.2 inch can exceed 600 nits, so there is no problem to see the screen on a sunny day.
