Angularjs + ionic + 'h5 + 'implements QR code scanning. angularjsionic
I would like to share with you todayAngularjs and ionicThe Framework supports QR code scanning on mobile phones. Cordova and Other plug-ins are not used, implemented by h5 +.
Development Tool: hbuilder
First, you need to introduce the "Barcode" configuration in the configuration file under the hbuilder project. The specific steps are
Last time we talked about WVS password protection (Web Application Security Series: install and configure WVS (II). In fact, there is still a lot of content about WVS configuration, the first two articles can only serve as an example. If you have any questions, please contact me. Starting from this section, we will discuss WVS vulnerability scanning, which is about to enter the practical stage.

The vulnerability project is
Now the two-dimensional code everywhere, whether it is physical goods or a variety of vouchers are the two-dimensional code of the figure. Mobile devices, such as mobile phones, have become a good application platform for QR codes, and we have basically used the third-party class "ZBarSDK" before iOS7, but after iOS7 Avmetadataobject provides us with an interface for parsing two-dimensional code, because its own research on this piece is not deep, after finding the data found that the use of

It can be said that it is an entry to the scanning line of computational ry. It's quite simple. You have to think about how to build a line segment tree. The other depends on the CAPTCHA.

Convex Hull
(Only for Convex packets in two-dimensional planes)
I. Definition
Simply put, there is a set of N points in a two-dimensional plane S. Now you need to select a point set C, and the points in C form a convex polygon G, so that all points in the s set are either within g or on g, and the area of the convex polygon is minimized. What we need is the C set.
Ii. Algorithms
There are many algorithms for finding convex packets. There are two common algorithms:

Background:
The hard drive requires 12 V 5 V power supply. Previously designed, the hardware circuit is valid for 5 V by default, and the 12 V power is invalid. Then, the system drives 12 V power, which is equivalent to 5 V first and 12 V later for the disk, this method is applicable to most disks, but for Hitachi hgst disks, cold start (or reboot after 12 V is not enabled, so that reboot after 12 V is enabled will be enabled due to 12 V and 5 V
Adaptive scanning SequenceAlgorithmIn three steps:
The Prediction between frames is initialized as a set of two-dimensional arrays {S1 [N] [N], S2 [N] [N],..., Sm [N] [N]}, where M is the number of inter-frame prediction modes, and N is the size of each dimension of the conversion.
For 4*4 conversions, n = 4; 8*8, n = 8; S is used to save the sum of the coefficient matrices.
2. For each n * n Block

However, I recommend that you do this, but some friends may not like server scanning. Do you want to enter the system quickly? Come with me ..Command method: Start → run → cmd input: chkntfs/x drive letter (which is the drive letter to prohibit scanning) such as chkntfs/x c: d: e: f:OK.
1. PrefaceToday introduced react native to realize the function of QR code scanning. First, we need to use the third-party plug-in react-native-barcode-scanner-universal to achieve cross-platform QR code scanning.2. IntroductionReact-native-barcode-scanner-universalReact-native-barcode-scanner-universal is a combination of React-native-barcodescanner and React-native-camera, The React-native-barcodescanner
Function: Batch port scan, can adjust the number of background scanning process according to the configuration of scan hostImplementation: Use the NC command to scan the port and use the pipeline feature to control the number of background scanning processesInsufficient: Only the scan port status is down to record the information, and no other alarm operationUse: You need to provide a configuration file con

This article mainly introduces the multi-threaded port scanning tool implemented by Python. the tool implements the single IP address scanning and IP segment scanning functions.

The latest version of Metasploit is 4.0 and can be downloaded directly from the official website (www.metasploit.com) because it is open source, so it's free.Metasploit is very good and powerful, integrates more than 700 kinds of exploit, but if the operating system is full of patches, it is still difficult to invade, so in order to test, choose the oldest version of Windows XP, is not with any SPX patch, or you can choose Windows XP SP1 version, the more loopholes, the more prone to attack.Open

You can use different IP protocols to send different packages to the target host. You can also use different ICMP requests to determine if the target host is online.

In this section, we will discuss the scanning input.
Most of the time, we need to read the corresponding text from the text file and process it. When the input is somewhere else, we need to scan the input as described below.
