How to delete linux and grub on both systems! -- Linux general technology-Linux technology and application information. For details, refer to the following section. The computer uses a dual system, xp is mounted on drive C, and linux is mounted on drive F,
1. In xp, the F disk is formatted directly to kill linux,
2. Install the dwarf dos toolbox,
3. Restart and boot with grub. Enter grub> chainloader (hd0, 0) + 1
Grub> boot
When you enter the XP

Leb128 (little endian base 128) is a variable-length data format (variable number of bytes) which can be divided into unsinged leb128 and signed leb128.
It can be used to store any large integer in a small number of bytes.
I. Encoding unsigned leb128
The calculation method is like this (dwarf-2.0.0.pdf Appendix 4 99 pages)
do{ byte = low order 7 bits of value; value >>= 7; if (value != 0) /* more bytes to come */ set high order bit of byte; em

use the Atos command to symbolize a specific module load addressThe command is:
Atos [-O appname.app/appname] [-l loadaddress] [-arch architecture]
Pro-Test, the following 3 kinds can be:

want to develop Windows programs, you need to choose Win32, and you need to choose POSIX for developing programs under other operating systems, such as Linux, Unix, Mac OS, and so on.Action: I only developed a program that runs under Windows, so I chose Win32.13. Select the exception handling model (64-bit)Description: Exception handling is important in the development process, where you spend most of your time working on various anomalies. If you have previously chosen 64-bit, there are two ex

Other symbol table formats are coff,dwarf,stabs and so on. (Mac os defaults to dwarf.) Dwarf is also based on COFF implementation [Common Object File Format])

Determined to write a family commonly used 5 ,7 Battery purchase and use Raiders for the general consumer reference. Other models of batteries, if you need to add later. One, the common Battery model: No. 5 Battery,No.7 BatteryThe most commonly used battery in the family is the No. 5 Battery and the No
the first time. When a program creates the first reference to a static member of a class, the JVM uses the ClassLoader to find the same name based on the class name- .class once the object of a class Class is loaded into memory, it is used to create all the objects of the class. A constructor is also a static method of a class, and using an new operator to create a new object is treated as a reference to a static member of the class.Note Exceptions: If a static final value is a compile-time co
Java uses a class object to implement its own RTTI capabilities-even if all we have to do is work like styling. The class class also provides a number of other ways to facilitate our use of rtti. The must first obtain a handle to the appropriate class object. As shown in the previous example, one approach is to use a string and a Class.forName () method. This is very handy because you do not need an object of that type to get the class handle. However, for a type that is of interest to you, if

they can be automatically converted to the same data type. During automatic conversion, the system converts low-precision data types to high-precision data types. In UNION statements that contain multiple queries, the execution sequence is from left to right. Brackets can be used to change the execution sequence. For example, query 1 UNION (query 2 UNION query 3) INTERSECT. EXCEPT t INTERSECT is the intersection. distinct t indicates the difference set. select user_id from user intersect select
