One, there are also many times when a certain ** ticket has risen, but the section has not been affected, which means that the company has introduced a certain policy, which is only good for itself. The second is that the introduction of a lot of news is for the formation of good or negative news in the sector, especially the news issued by the state, few of which are only aimed at the first, and at this time, a first-class ticket is the first to rise, and others often follow one another. At this time, the internal motivation is the psychological factor, as if two groups of people (long and empty) are together, and there must be one who makes the first move.

**Well, of course you can**. In this section, the investment value is relatively large, and the more active ones tend to become the leaders, while those with mediocre investment value will not become the leaders.

Can be used as a reference. When most of the ** in a section have high investment value, and some of them do not have any investment value, the worthless ** it will also rise a little, but this kind of **, generally you will not buy, so this as an investment reference, is it necessary?

The first question: In fact, it is not more about a small number of stocks with a whole section, but more hot spot conversions, and the fluctuation of national policies or material products, which is good for a certain line, then it is generally the whole line. It's not that a ** drives the entire section, especially like the power sector, there is basically no ** with the entire industry.

The second question: for the **, it is basically the valuation, and the most important thing is like the end of the year now, and the speculation is the company that will greatly improve its performance next year and have good earnings this year. Institutional shareholding, which is an evaluation, is estimated based on the current stock price and the company's market capitalization, and performance.

Like Guannong shares, is a typical example recently, 08 years will have key projects put into production, so a implosion rose 130%.That's a kind of ** and hype about the future.

The third question is basically the same as above, but it is necessary to speculate on stocks with exact news, not to speculate on bears.

It is often said that what section to buy recently, this is a short-term market operation, but from the current situation, the loss of speculation is more, from May to the present, the loss of money is basically the first operation, medium and long-term investors, basically no loss. This is also the theory that confirms China's development in the world.

The few that drive the board fast are mainly due to the change in everyone's perception of the industry, rather than to individual companies.

Of course, you can do a certain **, but no one can accurately grasp it.

Many people often use this operation in actual trading, but it is necessary to understand the internal reasons for the rapid rise and fall of the board and make a general judgment.

Only those who are most sensitive to the market can make good investments.

1 The leader in the sector** can drive the rise and fall of the plate. The current market is an international market, and it is no longer the old pattern of eliminating the advantages of one and the other. The reason is simple: the boss makes money, and the small ones are also divided.

2 A certain master said: Any ** is ridiculous and ignorant. Of course, as long as you have a factual basis, you can still **.

3 This kind of **: It is most suitable for doing bands, grasping steadily, and the income is high and fast.

Don't bother to analyze **, **If you can analyze it, then people will get rich, this thing is gambling, relying on luck.

1. Efficiency is equal to useful work (rate) and total work (rate).

Useful power = 360*

The total power of the liquid Hezhipai = 180W

2. Overcoming friction = total work - useful work - overcoming the work of gravity buried by the pulley.

It's not hard and it's not easy because you don't know what style of song you like.

No, but you can try it out below.

Brother Bird just talks about the operation and use of Linux, and it has little to do with embedded. You can learn C, because Linux is written in C, and C functions can be called directly under Linux. Then it's a matter of looking at some of the bash and perl programming columns.

As for apache, sabma, mysql can be left unread. Unless you're going to take the RHCE or LPI

If you really want to take the Linux certification, you'd better sign up for a class, and with your current learning progress, you can have another 3 months. When the time comes, the teacher will give you the question bank.

It is best to do an internship in the company to ensure that what you see is definitely something that you can't find in books.

1. Some units will look at it, and RHCE still has a certain gold content.

2. Linux + embedded is currently a fairly high-end profession. Suggestion, training course to learn embedded development.

3. The study time for RHCE certification only takes two months, depending on when the exam will be arranged for you.

There is basically no certification in the embedded direction.

And in the embedded direction, you have to learn single-chip microcomputer, arm, buy a development board to practice writing drivers.

The Red Hat certification for Linux is useful mainly depending on what job you're looking for, and the computer unit will look at.

It depends on what class you are enrolled in.
