started quickly.There are many reasons to tell us not to take the shortcut, to step by step, yes, some things are more complicated, take the shortcut easy problem, but for the Learning programming language, for people this really is not a difficult very complicated problem. Beginners find it difficult because these languages completely subvert previous perceptions and cannot immediately find the connection between actual things in life and programming languages.A lot of things actually have sho

Java.lang contains some classes that form the core of the language, such as String , Math , Integer and the Thread . java.awt contains a toolkit for composing abstract windows ( AWT class, the package is used to build and manage the graphical user interface of the application. Java.applet contains the executable applets a class of special behaviors. The java.net contains classes that perform network-related operations and classes that handle interfaces and Uniform Resource Locators (URLs) . The

: about the testing processI would like to know how the software development process is very specific module testing and the overall test is how to establish a link, this is what I do not understand now, is not to say that the answer to the question now. I would like to follow the next study in depth, I will be in the specific project to carefully understand the actual work.Question four: about the teamThrough the course study, we know that the concept of the team is very important in software d

programming must use the GNU C Kernel programming lacks a memory protection mechanism like user spaceThe memory in the kernel is not paged. Difficult to perform floating-point arithmetic during kernel programming The kernel gives each process only a small fixed-length stack Because the kernel supports asynchronous interrupts, preemption, and SMP, you must always be aware of synchronization and concurrencySMP: Symmetric multi-processing system.Common ways to solve competition: sp

, although the protection mechanism of some stacks was blocked (the method that was found on the net), but never compiled. Had to do in the experimental building buffer an experiment, the experiment also success rate. Although the entire experimental process is based on the steps of the lab building, it also complements some of the important knowledge that is available online. Through this practice, the "stack" has a deeper understanding, but also more familiar with the buffer overflow attack Th

testing the new algorithm.2. Using Condition variablesYou can use conditional variables If your code is not process-independent, or if you want to have a mechanism that can be used for all situations to control an attribute.This is easier than using UID, just to create a global variable as a conditional selector switch: If the variable is 0, the code on one of the branches is used; Otherwise, select a different branch. Control mode: Some kind of interface, or debugger.3. Usage

Why?Answer: At least can be lossy compression, if there is redundancy (the source of non-equal probability distribution) can also lossless compression.3-12, equal probability distribution of the source can also be compressed?
