will ultimately depend on how you use the language to create a stable and fast application.　　9. Inexpensive applications mean low qualityIn the market environment where open source is becoming the mainstream, free and open source is the biggest advantage of PHP. This means that most developers with expertise can provide development services and can also save costs for customers. But that doesn't mean there's a problem with quality, and it's also possible to develop high-performance applications

Hibernate 3.1 's query, the main code is as follows: Project Project = (project) session.get (Project.class, 1); The primary key type in the MS SQL 2005 database is bigint. Using the main aspect test, it appears: org.hibernate.TypeMismatchException:Provided ID of the wrong type. Expected:class Java.lang.Long, got class Java.lang.Integer Or use JUnit tests to appear: Java.lang.ClassCastException:java.lang.Integer cannot be cast to Java.lang.Long

Question: Got error from storage engine Reason: There is not enough storage engine to execute this SQL statement. Solution: 1. On the Linux server where the database is located, use DF to view the disk usage. Note: DF is based on the overall file system to determine the size of the allocated space in the system through unallocated space in the file system. The DF command can capture how much space the hard disk occupies and how much space is left,

Android-based Elf Plt/got symbol redirection process and elf hook implementation--by Low-end code farm 2014.10.27 IntroductionThere are two main reasons for writing this technical article: One is to find that most of the articles on the Web describing the Plt/got symbol redirection process are aimed at x86, such as "redirecting functions in shared ELF libraries" is very well written. Although t

The ELF can generate a special code-the location-independent code (Position-independent code,pic). The user uses-fpic to instruct the GNU compilation system to generate PIC code for GCC. It is the basis for implementing shared libraries or sharing executable code. The peculiarity of this code is that it can be loaded into the memory address space of any address execution. It is also convenient for the loader to dynamically link shared libraries in the process. The PIC implementation uses the fac

Plt, got, pltgot I recently learned about linux advanced debugging technology. The following is an experiment on dynamic library connection. First, we understand that plt is procedure linkage table, and got is global offset table. The got table stores external symbol addresses. The plt table stores the function address. Next, let's take a look at the lab details.

1. When I got my marriage certificate, it rained out. My husband looked at me and said, How many sisters shed tears. 2. My husband said, "you are mine. From now on, my monthly salary will be charged! 3. no longer need to drive without a license. 4. Take it home and show it to our son. 5. Let's explain it. Alas! 6. It is easy to go out of the city. 7. You may not have to accompany you every day. 8. Is it cheap to get married ...... 9. Say "yes"

The got plt resembles the IAT (Import Address Table) in a Windows PE file.To make the code address irrelevant, the basic idea is to put the relevant parts of the address into the data section.The elf's approach is to create an array of pointers to these variables in the data segment, called Global offset table,got, which can be indirectly referenced by the corresponding item in the

need to be changed because of the load address changes during loading. The basic idea of implementation is as follows: separate the modified parts of the command and put them together with the data, so that the command part can remain unchanged, and the data part can have a backup in each process. (PIC) 8> divide the modules in the shared object into the module internal reference and the module external reference. Different reference methods can also be divided into command reference and data

It is determined by the specific conditions that the old saying cloud "will not be given permissions to others", even though there are Organization regulations in the work field. As the project owner, I have formulated a work specification to ensure the smooth development of the project, which sets some requirements in daily work and life, including work schedule and so on. This specification was discussed in the entire project group and was unanimously recognized by everyone. That is to say, I
