1: I don't want to go offline in my desktop. So I went to a certain East to buy a USB wireless network card. The WN725NUSB of tp is very small, which is about the same size as that of the Logitech USB adapter. 2: The driver can identify it by itself. since it is a usb Nic, after the USB is inserted, lsusb will see a new line of Realtek id0133: 8179root @ debian:/# lsusbBus00 added.

1) Windows XP has bugs
Windows XP has a shutdown error, if your computer in the process of shutdown is often a blue screen shutdown, and the fault is intermittent, press the "Ctrl+alt+delete" button also has no response, then you can be sure that your system has not been patched accordingly. Please download SP1 patch pack on the patch, generally on it.

Description
You can use this exercise to understand the definition of classes and objects;
Design a point class Time, which has private data members x (x coordinate), y (y coordinate); Public member function: SetPoint (int, int) is used to set the value of the point object, showPoint () is used to output the information of a vertex obje

First , we use the first method: Inherit the Defaulttypeconverter class under the OGNL package, and do a type conversion:Create a new input.jsp:Next, write the processing class and create a Pointaction class under the Com.test.action package:Package Com.test.action;import Java.util.date;import Com.opensymphony.xwork2.actionsupport;import Com.test.bean.point;public class Pointaction extends Actionsupport{private point Point;private point point2;private String username;private int age;private Date

Through the experiment I found a method, that is, in the interrupt function to make an additional counter, if the counter does not reach the set value, then reload the Feed dog Timer initial value, while the setpoint added 1, when the counter reached the set value, do not load feed the dog timer value, The watchdog timer is then reduced from 0x40 to 0x3f to produce a system reset. Using this method, you can exten

Incremental PID Control C-Language code
Incremental-PID Control formula:
The above U (k) is the amount of control increment, and "incremental pid" is controlled directly by this increment.
As for the parameters of the adjustment, according to the situation of the response, for example, slow response, I will increase KP, or reduce KD, overshoot, on the reduction of KP or increase point KD, this rule you can see the function of PID three parameters:

Input device performance is also the key to improve office efficiency, you need to choose a good ergonomic design, feel comfortable keyboard or mouse, but also give priority to wireless models, because it can effectively avoid cable winding, reduce efficiency. As for the form of wireless transmission, usually using a 2.4GHZ USB receiver device compared to Bluetooth has a more stable performanc
