How QT compiles BTC

1. Modifying G + + compiler with QT Creator

2. The reasons why websites are not included in the Internet are as follows:
1. Content plication
content enrichment includes two aspects: one is template plication, the other is article plication
2. Excessive SEO
the network's punishment for excessive SEO websites is becoming more and more serious, which will lead to less or no collection on the network. Content is the most important, even if your chain is very strong, for a period of time do not update the original content, the network is lazy to pay attention to you
3. Revision
business is not good, the whole counter and traffic is not high, the whole website. In fact, the website is also like a person. A person often changes his face, but also has to let the people around you know you again. This needs a process. Once the website is planned and the section is fixed, don't change it easily. If you don't have to make a revision, try to keep the original path. You can make some minor changes, but don't make any drastic changes. It may have little influence on some big websites, but it's fatal for small start-ups. This is the same as a person's face, acquaintances don't know you, the network also can't recognize your website
4. Host space
if the space is unstable, the website can't be opened easily, the opening time is too long, and the network connection can't catch the corresponding information after two or more updates, then you must be cleaned from the database, because the network thinks that your website has been closed or the page doesn't exist. Another is that you cheat on the same IP for many times, and you'll also have bad luck
5. Links
check the external links of the website regularly to see if there are dead links, junk websites, websites not included by the network and websites with reced rights. These websites will lead to less or no included websites. If there are similar links in the website, they should be deleted as soon as possible. To develop a good habit of adding links, regularly and step by step to add the chain, many friends on a whim, read the article said that the chain is very important, all day long to add group for friends chain, everywhere outside the chain, this is taboo, search engine is easy to determine that you are cheating, so have a regular to
6. Website security
if you add malicious code to your website or hang up your horse intentionally, the network can analyze it and rece your trust. And don't be hacked, modified or deleted by Heike. In order to prevent similar problems, it is best to back up regularly and solve the problems in time. Generally, the network does not update many personal stations every day. If it is abnormal, it should be avoided to deal with it immediately. Well, if you think it's useful, you can collect the website of Guangzhou website construction directly. We can communicate with each other and learn together.

3. Generally, the first thing you think of is to log in to the major search engines and submit your website URL to them one by one. This method is out of date. At present, it is the most passive and ineffective method. Google guy has also said that the importance of submitting URLs to Google is decreasing, and the attractiveness of submitting URLs to Google is getting smaller and smaller. For this part of the data submitted to Google, the update is very slow. If you only use this method, you may not be listed on Google in two months
What's more, submit to some public directories, such as dmoz.org. For a new website, there is not much content. It will take a long time to list in these large directories, which may take a very long time. Therefore, it is not advisable to find it quickly by Google and other search engines. Of course, you can submit it and wait to be included slowly
the following is the fastest and best way to get as many external links as possible. These links are not necessarily on the home page of the linked website, but on the inside page. In fact, your website has just been built, and there is not much traffic, so it is not easy to find some good home page links. It's best to find some websites with higher PR value (such as above 6) and more updated content every day. Google will roam and update its database every day. When Google finds your URL when roaming these sites, it will follow the URL to crawl your site. I have used this method many times before, which is very effective. Of course, I don't need to use it now. Just make a link on the homepage of a website with higher pr.
which method is usually used will be listed by Google and MSN in 2-4 days. Yahoo is a little slower, it may take 1-2 weeks, which has something to do with its search technology. How can we make some links in some websites with high PR and fast update? In fact, it's very simple. Many websites have forums or allow comments. Just sign your name, bring your website address and send a few posts or comments. But this kind of URL must be active, that is, you can click to reach your website. According to the author's experience, after Google finds your URL, it will roam your website on the same day. One or two days after roaming, it will search your website in Google and find that your website has been listed. For the first time, it will only be your home page, which Google and MSN share
next, let's talk about the reasons mentioned above for getting as many links as possible. If you have only one link, it's OK to be listed by Google in a few days, but it's only the home page for the first time. It will take some time until Google includes more pages, maybe 1-3 weeks. This is because Google's roaming cycle to a new station will be longer. If you have more links outside, when Google roams those websites, it will find that your website will come to crawl your website again. The more Google crawls, the more frequent it is. At this time, it will roam your website deeply and include more pages. This will greatly shorten the Google included time, so that Google included more pages in a shorter time
in the collection of a new website, the author's experience is that Google has the fastest response, the fastest collection, followed by MSN and Yahoo. Google included in a few days, if there are many links, it will be included again in a few days. In addition, your website is updated every day, the content is updated ordinary, and the internal URL structure is reasonable. In a month, it will be deep roaming, and all your web pages will be included. MSN's listing speed is similar to Google's, and it's also very fast. But generally only included the home page, to include more pages again, it may take about 2-3 weeks. During this period, if you go to MSN to check your website, you will always see a home page there. After 1-2 months, MSN can completely include your website. Yahoo's response is the slowest. It takes 1-2 weeks for the first time, and it may take 2-3 months for full inclusion
finally, abandon the passive methods of actively submitting links to search engines, and make more high-quality external links, you will have unexpected gains

4. Network system problems, the old station's capture frequency has not been updated since the 25th, the index is also updated and not updated, this word may be the network to have a big update, and so on will have

5. Although the origin of clocks and watches can be traced back to the 13th century A.D., it took only 130 years for them to conquer the time obsessed human beings. Whether it is worn on the left hand or right wrist, what the watch can convey to people is not limited to time information, but a symbol of class and popular pointer. A good watch can not only become a tie, but also a symbol of a man's personal taste. It can also become a treasure beyond time and space
from conservative to fashionable, watches are changing faster and faster nowadays. However, watches, after all, are "unpopular goods" that require a high degree of expertise. Even speculators who love money but not watches have to pay attention to such "classical concepts" as movement, workmanship, decoration and inlay at the beginning. At present, the most popular one is probably the material that makes watches
among the top ten watches in the world, they all have noble pedigree, distinguished status, glorious history and expensive value. Their price is more than six figures of RMB, which is similar to the price of a mid-range car in China. And their outstanding contributions in the history of their respective clocks and watches can be called the pinnacle of human mechanical manufacturing wisdom<

first place:

Patek Philippe: the symbol of nobility

Antoine Norbert de Patek, the founder of Patek Philippe, was a revolutionary of Poland against Russian rule in 1831. After the failure of the Polish revolution, he fled to France, settled in Geneva, Switzerland, and began to work in the clock and watch instry. In 1839, he set up Baida watch company. In 1844, Antony Baida and Francois Czapek met at an exhibition in Paris. At that time, Jane Philippe had designed a pocket watch with a very thin case and no traditional key was used for chain up and adjustment. This kind of pocket watch was ignored at the exhibition, but Anthony Baida was deeply attracted by his new design. After a conversation, they immediately reached the intention of cooperation. In this way, Jane Philippe joined Baida company. In 1851, Patek changed its name to Patek Philippe
the cooperation between Anthony Pater and Jane Ferri is a perfect match. Anthony Baida has deep attainments in art, tends to aestheticism, and pursues perfection and high level in clock making. Jane Feili is a gifted designer and inventor. This combination determines that Patek Philippe clocks and watches follow the path of exquisite appearance, excellent workmanship, superior standard and meticulous, and adhere to the three principles of "elegance, high quality and reliability"

symbol of solemnity and bravery

Patek Philippe's logo is composed of Knight's sword and priest's Cross, also known as "kaledoraba cross". Its origin is: in 1185, a Spanish city called caledoraba was invaded by the moors, and the brave clergyman Raymond and knight Diego bellaskes led the people to fight to the death, and finally drove the moors away. The priest (cross) and the knight (sword) together become the symbol of solemnity and bravery. This symbol just represents the spirit of cooperation between Anthony Pater and Jane Ferri. The label has been in use since 1857

original model

Patek Philippe's exquisite manufacturing technology has created many top brands. In 1927, at the order of the American car king pergard, the company proced a reed watch that could play his mother's favorite lullaby. At that time, it was worth 8300 Swiss francs. At the request of Griffith, a New York collector, Patek Philippe spent five years from 1928 to 1933, including time, time difference and star chart. Its exquisite, set a milestone in the history of watches. In 1985, Patek Philippe's 940 multi-function watch has the functions of full-automatic, calendar, phase of the moon, leap month, automatic jump day and so on. The thickness of the body is only 3. 75mm, the thinnest of its kind

forge ahead with determination

in order to achieve further development, Patek Philippe officially issued Patek Philippe international magazine in October 1996, which was published in English, French, Japanese, Chinese, German and Italian, trying to attract customers and enhance the corporate image through the content of the magazine. All of these prove that Patek Philippe's business philosophy of constantly seeking innovation and change makes this 100 year old factory still full of vitality and vigor

early history

Patek Philippe got a great honor after its establishment: at the 1851 London World Expo, Queen Victoria of England selected and bought a Patek Philippe bag watch. This pocket watch with a new handle hangs on a gold pin inlaid with 13 diamonds, and the enamel blue gold cover is decorated with diamond roses. At that time, the Queen's husband Prince Bert also bought a Patek Philippe hunting watch. Patek Philippe established its aristocratic status when celebrities bought high-quality procts. In order to pursue the high level of procts, Patek Philippe spared no effort in material selection. The early Patek Philippe case was made of pure silver and 18K gold. Since the 20th century, most of them have chosen 18K gold (including gold, platinum, rose gold, etc.), even platinum. However, only a small part of the all steel watch case came later. The movement of Patek Philippe watch adopts high number of drills. In the early stage, most of the watches were more than 15 drills, while in the later stage, most of the watches were 29 drills. In the 1960s, some gold watches with complex properties were made, with a drill count of 37, which is rare in the same kind of watches

superb skills

Patek Philippe has always been in the leading position in clock technology and has several patents. Since "Patek Philippe" won the first patent of "winding up the handle" in 1851, the major patent items include precision regulator, double timer, large spiral balance wheel, peripheral automatic chain rotor, and the balance wheel axis device, etc. From 1949 to 1979 alone, there were 40 patents, the number of which was the most in the list

Viagra procts

Patek Philippe has strict restrictions on the proction of watches, with no more than 10000 each. Nearly a century and a half have passed since the establishment of the company, and its total output is only 600000. Quality procts with limited quantity make Patek Philippe watch have the function of keeping value. In 1989, the commemorative watch proced to commemorate the 150th anniversary of the founding of Baida company increased four times in value by the early 1990s. In 1953, a platinum inlaid diamond Sun Moon Star calendar man's watch was bought by a European buyer for HK $5.3 million at the ྜྷ spring auction in Hong Kong, breaking two records of the highest transaction price of the calendar watch and the highest auction price of the Asian watch

modern and traditional are compatible

at present, Patek Philippe is still the only manufacturer in the world that adopts manual refining and can complete all the watch making processes in the original factory, and adheres to the traditional process of clocks and watches. The Swiss watch instry calls this traditional manufacturing technique "Geneva's seven traditional watchmaking techniques", which means a combination of the traditional techniques of designers, watchmakers, goldsmiths, watchmakers, sculptors, porcelain painters and jewelers. Patek Philippe firmly believes that the watches made by such craftsmen are unique art treasures, which is also the most proud feature of Patek Philippe watches. In order to break through the tradition and create a more ideal working environment, Philippe stone, the current president and managing director of Patek Philippe, began to plan and build a new factory since 1988, in order to "combine Patek Philippe's unique technology and technology under one roof". After the new factory was completed and put into operation, it became a complete "watch making" factory. An old castle beside the factory was renovated into a private collection Museum in Geneva<

Vacheron Constantin: noble works of art

founded in 1755, Vacheron Constantin is the world's oldest watch manufacturer and one of the world's most famous
Vacheron Constantin has inherited the Swiss traditional tabulating essence, has not stopped, and has also created many tabulation technology, which has made a great contribution to the watch making instry.
in 1755, founder Jean Marc Vacheron and later member Francois Constantin, with their foresight and superb watch making technology, finally took the lead in establishing Vacheron Constantin, which is famous for its emphasis on humanistic spirit and historical inheritance, in Switzerland, a watch Kingdom full of talents. After 243 years of time washing, today, Jiang shidanton seems to be a synonym of "time", and is an irreplaceable wrist art in the eyes of watch lovers

with a long history, Constantine has many years of tabulation experience and many great classics. However, "the smallest batch, the best quality, the highest selling price" has always been the business strategy of Constantine. Today, the annual output of the factory in Geneva is only 6000 meters. Since 1840, the proction drawings, records, sales dates and case numbers of each watch have been kept intact in the company's filing cabinet. They combine superior technology, strict testing, exquisite craftsmanship and perfect modeling together to create one after another noble, elegant, amazing and rare classic works with great collection value. In the long years of tabulation, it has become a symbol of nobility and elegance
"Martha cross" is the mark of Johnston. It was originally a precision gear used to adjust the spring tightness in the era of hand-made watch making. Only with its symbol of superior skills and manual tabulation tradition. Carlista, a classic by John J. constanton, is the most expensive watch in the world. This watch was made in 1886. It was originally ordered by King Khalid of Saudi Arabia, but King Khalid died ring the manufacturing period. After the watch was made in 1986, it was bought by an unknown buyer with us $3.5 million. On December 3, 1987, harimi changed hands again and was bought by piene halini, the owner of palm beach. Harimi claimed that he made the deal with us $5 million. As a result, cariste watch appreciation of $4000 a day spread. Soon after, Pierre harimi brought the world's most expensive watch into the United States and gave it to an unnamed buyer

unique and extraordinary design

Jiang shidanton is famous for its technology all over the world, and is good at manufacturing complex mechanical watches. Take the new watch saltarello of Les complications series as an example. The transparent crystal at the bottom of the watch is convenient for the wearer to enjoy the dynamic beauty of mechanical operation. Due to the high proction requirements, this famous watch is limited in quantity. Jumpinghour's design is even more exquisite. It displays time in a 12:00 window and minutes in a semicircular ring. It is called a jump time meter, which is very rare<

Master's pondering and time's test

Tourbillon's watch system is another masterpiece of Constantine. It can be appreciated through the crystal sapphire surface. The precise, elegant and unique power storage display fully shows the profound mystery of time movement. Thor billon, a classic work, perfectly reproces the motto of Constantine: perfection is everything. Exquisite craftsmanship has laid the foundation for the creation and proction principle of Constantine. Because of this, every finished proct of Constantine has to be tempered for several years, and each scale reflects the master's meticulous carving<
