First, the synchronization problem proposedThread synchronization is a breach of data that prevents multiple threads from accessing a data object.For example: Two threads Threada, threadb all manipulate the same object Foo object, and modify the data on the Foo object.public class Foo {private int x = 100;public int GetX () {return x;}public int fix (int y) {x = XY;return x;}}public class Myrunnable implements Runnable {private foo foo = new Foo ();pu
that "Safe_mode_include_dir =/DIR/INCL" will allow access to "/dir/include" and "/dir/incls" if they exist. If you want to control access to a specified directory, add a slash at the end, for example: "Safe_mode_include_dir =/dir/incl/". If the value of this directive is null, files with different uid/gid in PHP 4.2.3 and PHP 4.3.3 will not be included. In earlier versions, all files could be included.

then use it to send a check-in reminder to the user. However, in many cases, the user forgot to sign in one day, the system loses the user's permission, causing the user to disconnect from the contact; For example, the system would like to proactively inform users of the upcoming activity, however, due to the small program passive trigger notification restrictions, the system will not be able to actively push messages.
How do I make the push of template messages not restricted?

The above code uses the MD5 algorithm to calculate the hash of the user name string, converts the computed result into a 32-bit 16-digit string, and then takes the odd bits of the string back into the new string, which becomes the registration code. Then there is a judgment statement.Next he wrote a simple interface that asked for a username and registration code, and then clicked the Register button.2.2 Cracking the first programCrack the program written in 2.1.

There are two ways to get there, either directly from the computer's AppStore, or from Apple's developer center. The difference between the two is that the latest beta version is downloaded from the Apple Developer Center, but does not support automatic Updates. It is necessary to note that because of the recent breach
-data user ID, all users hosting the Web site must ensure that the user can read their files by default. Therefore, all other users on the system may access all Web-accessible files of a user, so a security vulnerability that is not related to you on the system can be a breach of your Web site. This can be more serious if the file or directory must be set to Www-data user writable.By using CGI programs, such as those written in popular languages such
rebuild the new Odex. Therefore, if the attacker wants to inject the target Odex, the modified Odex file's CRC and Modwhen will need to be modified.The following is a modified Odex file instance, Dex_old is the modified Odex file, Dex_new is the modified Dex file, two files md5 different, but CRC and Modwhen is the same, This allows you to bypass the Dexclassloader checksum .Five.

Applicable scenarios:One of the popular automation operations: Ansible is based on SSH communication. Therefore, before using ansible, you need to resolve the SSH communication problem between the Ansible server and each managed node first. The first method is to use the user name and password to SSH communication, the password needs to be stored in plaintext in the ansible hosts file, there is a security breach of the password. The second method is t

In real life we have a variety of agreements, but all have one thing in common, is the proposed agreement, we must abide by, non-compliance is a breach of contract. There is also the concept of agreement in OC and is similar to the characteristics of our real-life agreements. Sometimes we want to do something ourselves, but now we do not have the ability to do it ourselves, we need to find an agent to help us do. Then there is the concept of proxy in

(nonatomic, copy) Nsarray *__nonnull Studentarray;It is recommended to use nonnull this way, so that the property declaration will look clearer.However, for security reasons, Apple has also set several rules:
The nullability attribute of a type defined by a typedef is typically dependent on the context, and even in audited regions, it cannot be specified as nonnull.
A complex pointer type (such as ID *) must be shown to specify whether it is nonnull or nullable. For example,

Just as entrepreneurs face a variety of economic, psychological, and social pressures, engineers are faced with a variety of procedural problems, which could be a bug in a complex program, or it may be that the technology used by the company's services has been a problem.For example, a well-known GitHub attack, when everyone thought that Ruby on rails technology was safe, suddenly caught a serious security
