Instancetype as the return type of a function, there is no error.Consistency:Finally, imagine putting everything together: you want an init method and a simple constructor.If you use an ID as the return type of the Init function, the final code is as follows:- (id)initWithBar:(NSInteger)bar;+ (instancetype)fooWithBar:(NSInteger)bar;But if you use Instancetype, the code is as follows:- (instancetype)initWithBar:(NSInteger)bar;+ (instancetype)fooWithBar:(NSInteger)bar;The code is more consistent

Several solutions (instances) for generating unique IDs in php, phpid Php generates a unique id. There are many ways to check it online. 1. md5 (time (). mt_rand (1,000000 )); There is a probability that this method will be repeated. 2. php built-in function uniqid () The uniqid () function generates a unique ID based on the current time in microseconds. W3school reference manual has one sentence: "Because the system time is based, the ID generated th

We often use a system to automatically assign IDs as our primary key when designing a database, but there is no such function in Oracle, we The function of automatically increasing ID can be realized by taking the following functions 1. Create sequence first Create sequence Seqmax increment by 1 2. How to use Select Seqmax.nextval ID from dual You get an ID. If you put this statement in the trigger, you can implement and MS SQL automatically add ID th

Snort is an IDs (intrusion detection System) software developed by the U.S. Sourcefire Company under the GPL v2 Snort has three modes of operation: sniffer, packet recorder, network intrusion detection system mode. The sniffer mode simply reads the packet from the network and displays it as a continuous stream on the terminal. The packet logger mode logs the packet to the hard disk. Network intrusion detection mode analyzes the data stream in order t

NIDs uses the original network information as the data source, uses the network adapter running in the random mode to monitor and analyze all the communication through the network, collects the relevant information and logs it, while HIDs is usually installed on the detected host and connects with the host's network in real time. Responsible for the intelligent analysis and judgment of the system audit log. If an illegal intrusion or violation of statistical laws is found,

To effectively capture intrusion, IDS must have a strong database of intrusion characteristics, just as the public security department must have a sound criminal information base. However, IDs generally with the characteristics of the database are more rigid, encounter "face-changing" intrusion behavior often meet not acquaintance. Therefore, it is necessary for the administrator to learn how to create a ch

Questions raised: Intrusion Detection (IDS) is a special security device that is used to discover hacker intrusion. Early in the time is very simple, is a log analyzer, like a needle in the log to extract the hacker's visit records; Later, the hacker learned to be good, before leaving their own "stain" record all erased; The record is gone, log analysis is hard to find hackers Of course, some novice hackers do not have this awareness and ability. Now
