[Practice name] interprocess communication mechanism (link)

Lessons learned and deficiencies

• 1. Inter-process communication it is difficult to be confident about the extent to which the knowledge of this component has been achieved.

• 2. "UNIX Environment Advanced Programming" book content is relatively deep, to learn a certain foundation and strong interest, will be better. Think this is a good book, but I still do not understand. In practice, we have the most elementary and simplest knowledge and concepts about interprocess communication.

  First, interprocess communication can be implemented at least through the transfer of open files, where different processes pass information through one or more files, and in fact, in many applications, this approach is used. In general, however, interprocess communication (ipc:interprocess communication) does not include this seemingly low-level communication method. There are many ways to implement interprocess communication in Unix systems, and unfortunately, very few methods can be ported across all UNIX systems (the only half-duplex pipeline, which is also the most primitive form of communication). Linux, as an emerging operating system, supports almost all of the common inter-process communication methods under UNIX: Pipelines, message queues, shared memory, semaphores, socket interfaces, and so on. through practice, we learn and understand the communication mechanism between processes, recognize several ways of communication, and compare their advantages and disadvantages. The cognitive dimension to, try to understand some of the inter-process code. Of course there are deficiencies, in the process of searching for information, encountered the code of understanding, in understanding some blocking process, or indefinitely state.

Your own harvest.

1. In the process of practice, they learned to collect and collate data, look at different data, extract their focus, and put some simple code to try to run it again.
2. I feel that learning a knowledge, no matter what knowledge, with a pious attitude to learn, every learning a little, the breadth of vision, every learning a little bit of knowledge of the great, and this practice is not only closely linked to the course, but also let me on the operating system of the process of communication, have a more detailed understanding.
3. Some people say why to learn these, then what to use, then Baidu Check not good. But I think, knowledge is their own, perhaps I will forget these knowledge, but I think since met, why do not understand, why not look at the principle, the feeling of learning is always more than the brain covered with a layer of cloth, what do not understand good.

Where you need to improve.

In fact, in the process of practice, I encountered a problem, is to understand the level of the problem, do not understand the code, it is not written in the experimental report, because there is no way to debug it. I think I want to improve the way of independent learning and improve the ability to understand knowledge. Nothing is skyrocketing rise. Knowledge is hard to chew, but if you learn more, you will be contacted as a net. A book, for the first time I couldn't understand it, and then the second time, I suddenly found that I could learn so much. (Just like in-depth understanding of the book)

If you have a pair, write about the help you have provided or what help you have received, and provide advice to the teacher.

The subject of this practice is mainly focused on theoretical research. We started with no division of labor, in order to let each other learn knowledge, are their own research, their own blog, finally I and my partner to see each other's blog (my blog is now hidden released, two people's blog summary in the partner blog). Finally, we made a summary, the important feel good part to stay, together run a number of online process communication Small code, delete debugging.

To learn the younger brothers learn the sister's study advice if you re-learn this course, how to do to learn better?

1. I would like to say, must not buy pirated books! "In-depth understanding of computer" This book is very good, really very comprehensive. This is a lesson worth learning. Learn younger sisters, before beginning to learn, it is necessary to improve the importance of it. To study this book well, it is impossible to say that it is not hard, but you will find it worthwhile to finish the study in the end. You might even feel like you have to look it over again.

2. Reading not only to see the theory, remember to do after-school questions. Homework is better if you don't do it yourself. If you don't understand the problem thoroughly, you don't understand it.

3. Read this book can listen to the students usually discuss the topic, or the knowledge of the explanation, you will better understand the knowledge of the textbook, communication is a good way to learn.

What do you think the teacher should continue to do in the course of the teacher's advice?

Let the active students actively study, forcing the students to study hard.

What do you think the teacher of this class should stop doing?

Do not have to deduct points examination, originally worked hard, diligent, test score number is not easy. Although the study is not for the score bar, the weekly look at the standings on their own, are very scary. The pressure is still pretty big.

What do you think the teacher of this course should start to do new things?

I hope that the teacher can explain in class some of our after-school questions, or homework problems, in the course of the problem, the knowledge points to us to piggyback. Because sometimes, even if you read a book, I do not know that I understand the right.

Other things that you think are important

Insist on learning, no matter what, every week to learn, if the progress of a little.
