Ah ~ ~ ~ ~ ~ ~ to finish this problem feeling IQ is hollowed out ....1, firstly, because the horizontal ordinate is not necessarily an integer, it needs to be discretized according to the actual data;2, because my scan is from bottom to top, so the horizontal axis is discretized;3, from the bottom of the scan, when encountered a bottom edge will cover the numbe
How do I play the Star Wars app?
Use your ID card to draw the outline of the card on the white paper, then follow the characters shown in the center of the card map, and then use the Star Wars app to turn on the camera to display a variety of dynamic pictures. If you are too lazy to draw can be directly with the Star Wars app to scan the image below, the same can be more vivid dynamic effect oh. Paint a Star Wars app

A few days ago, I started to learn socket. I wrote a single-threaded single-host port scanner for one of the great help of yunshu. Today I want to change it to multi-host scanning, (The thread is still single and slow, but it can be used for learning. It doesn't matter if it is slow), but it won't be changed. Please give me some advice.

2. Install the scanner, if you have a CD-ROM, directly installed on the CD, if there is no CD-ROM, you can download the scanner through the Samsung website. ( scan software please click here to download, Scan driver Please click here to download.) )3. After the installer completes, the Single-page document faces down on the document glass.
Android Support library for scanning and identifying barcodesAndroid supports scanning barcodes. But there's no real machine in hand, and I can't understand whether the feature is an application or an API-calling feature. But find a free Open-source Android library that handles barcodes on the Internet.

Whenever I infiltrate the Intranet to face a large number of hosts and services, I am always accustomed to using automated methods to extract information from the NMAP scan results. This facilitates automated detection of different types of services, such as path blasting of Web services, testing of keys or protocols used by the SSL/TLS service, and other targeted testing.
I also often use Ipthon or *nix shells in penetration testing, which can be a
Each node in various IP-PUBLIC-VIP-Private-scan ip 1, PUBLIC, and VIPOracle RAC in RAC has a virtual IP address (VIP), which is in the same network segment as the public ip. The vip is attached to the public network interface. The main difference between VIP and public ip is that VIP is floating while public ip is fixed. When all nodes are running normally, the VIP address of each node is allocated to the public NIC. In the ifconfig command in linux,
NMap, also known as Network Mapper, is a web scan and sniffer toolkit under Linux.Nmap is a powerful scanner that is often used in network safety penetration testing. The power of function is self-evident. Here are some of its scanning commands. Specifically, we have to rely on everyone to learn, because it is too strong.1) Get the system type and open port of the remote hostNmap-ss-p0-sv-o Here the -ss TCP SYN Sc
1. Low Efficiency of fuzzy search:
Cause: like itself is relatively inefficient. You should try to avoid using like in query conditions; for like '%... % '(Full fuzzy) is a condition where indexes cannot be used. Full table scanning is very inefficient. In addition, because of the matching algorithm, the length of the fuzzy query field is larger, fuzzy query efficiency is lower.
Solution: Avoid fuzzy queries as much as possible. If fuzzy queries are required for services, do not use full fuzzy q
