These days leader let me use the Factory mode to reconstruct part of the business logic code, the process is painful (here is not detailed), the results are very sweet. Here's a note that I encountered a problem during the refactoring process.Some of the code is as follows:@service(orderfactory) Public class orderfactory implements iorderfactory{ PublicOrdercreateFactory(String type) {if(Type! =NULL Type.indexof ("1")! = -1){return NewOrderOfType1 (); } }}@service Public class OrderOfTy

I've also been learning about Linux development recently, especially the network programming piece. Today, share the first few days of the simple SYN-port scan code, rather than simple, rather humble, but indeed a lot of harvest.
I'm not here. Full port scan, SYN scan is different from full-attached scan, because this scan does not need to establish a connection, so the speed of scanning is much faster than the full-connected scan speed, with a p
A simple small program that uses thread pooling technology to implement port scanning (TCP):
The key code is as follows:

Trim (); if (portstart.length () = 0 | | portend.length () = 0)Return int s = 0;int e = 0; try {s = integer.valueof (Portstart);E = integer.valueof (portend);catch (Except
aware that in the Arduino display upload when the small e-Development board quickly power off, and then power on. Failure to do so will cause the upload to fail.
The following image is a screenshot of the successful upload:
Congratulations on your success.
Open the Serial viewer, you will find the small e-Development Board (ESP8266) is scanning nearby WiFi, and displayed in the string, is not a sense of accomplishment.

1.3 scanning line Seed FillingAlgorithm
The two seed filling algorithms described in sections 1.1 and 1.2 have the advantage of being very simple. The disadvantage is that recursive algorithms are used, which not only requires a large amount of stack space to store adjacent points, and the efficiency is not high. In order to reduce recursive calls in algorithms and reduce stack space usage, many improved algorithms are proposed, one of which is the

Q: If I need to run virus scanning software on a machine running SQL Server, what do I do without impacting performance?
A: The answer to this question depends on the type of virus scanning software you want to run. There are currently three types of virus scanning software-active virus scanning, virus cleanup,

Apart from IP detection, the hacker also has a port scan. Through port scanning, you can know which services and ports of the computer to be scanned are opened but not used (it can be understood as a channel to the computer ).I. Port Scanning
It is easy to find remote port scanning tools on the Internet, such as Superscan, IP routing, Fluxay, etc. (1 ), this is t
You cannot protect things you don't know. Although this is not a mantra in the IT security field, when you look for security vulnerabilities from the perspective of "trusted" users, or in other words, perform a vulnerability scan through identity authentication, this principle is true.
By configuring a vulnerability scanner to log on to the host you are testing, you will see the rest of the story-security aspects that are often ignored to save time or money, or because of complexity. The trut
