A ruijie RG-S2126G switch password forgotten, in order not to delay the use and configuration, decided to recover the password.1. First, connect to the control port of the switch through a PC.Open the Super Terminal on the pc and set 57600, data bit: 8, parity: None, stop bit: 1, data flow control: None, such:650) this. width = 650; "border =" 0 "alt =" "src =" http://www.bkjia.com/uploads/allimg/131227/02344W4b-0.jpg "/>

Test instructions: Given n line segments, the two endpoints L and r of each segment are integers. Then give M queries, each asking for a given two intervals [l1,r1] and [L2,R2], ask how many line segments meet: L1≤L≤R1, l2≤r≤r2?The solution, using the offline approach, first all the line segments and the query interval are all saved. Then split each inquiry [L1,R1][L2,R2] into two, l1-1, [L2,R2] and R1,[L2,R2]. x, [L2,R2] represents the starting point L Sorts all the segments by their starting p
the number unit of movement. A negative number is moved before the position, and a positive number is moved after the position.
Character is generally used in actual development. Several other parameters are different from the expected position when editing the Chinese environment and HTML.
Example 1: textrange selects the first 4 characters of the cursor
The Code is as follows:

application circuit of the ada4940-1, as described in its datasheet, VOCM is expressed as the output signal of the common-mode voltage, the size of the external input is determined by the input signal is independent of the common-mode voltage. There are two closed loops in the circuit, the upper and lower symmetry, in order to make the closed-loop performance consistent, two closed-loop parameters should be consistent. The following focuses on the implementation of ADA4940 as a single-ended-to
In the highly competitive athletics field, speed determines everything. For large Internet cafes, enterprises, and broadband communities, fast network speeds, stable lines, and a large number of hosts have become the best practices for competition and development.In this regard, ruijie network (the original real-time network) for large-scale Internet cafes, enterprises, broadband residential demand customized high-performance telecommunications Broadband Router
I recently read the beauty of programming to prepare for job interviews. In this book, I did not answer the question of 2.20 program understanding and time analysis, so I wrote my own answer briefly.

relatively difficult to find K.This is the problem that Elliptic curve encryption algorithm adopts.We refer to the point G as base point,K (KK is called the Public key (public= "" key). Now we describe a process for encrypting communication using an elliptic curve:1, User A selected an Elliptic Curve EP (A, B), and take the elliptic curve point, as the base point G.2, User A selects a private key K, and generates a public key k=kg.3. User A transmits EP (A, B) and point k,g to User B.4, User B
For a long time, websites in many units and departments have been infected by Trojans and often maliciously tampered with by hackers. As the website is the first facade of external communication, website security is always a sword hanging on the head of the Network Center Administrator!
Isn't website security really reassuring?
Of course!

words, what you really need is to reach the Internet backbone with a few "hops" that may be less. Good point-to-point network arrangement can pray for the role, at the same time, a good business-level network can also play a very important role. Here I do a high-speed comparison of my home network and work network:
The number of "hops" from Uverse network to google.com: 13

Components: Refers to the color component, OpenGL only allows the image format using the following 4 kinds: "R" "RG" "RGB" "RGBA", size defines the number of bits per component occupied (bit), type defines how the color format is used for storage, the values can include:
