Chapter 19 Illustrations

When Atletico Madrid did the problem by himself in the past few days, he found that for mathematics and science, e7u can provide 100% correct answers! Of course, either there are no solution steps, or the solution steps given are completely software programming code solutions that Atletico Madrid does not understand at all, which makes him very headache.

On the surface, after e7u absorbed the three major mathematical software, it only improved the speed of problem solving, and the quality of the "answers" was still not satisfactory.

But in fact, after absorbing the algorithms of these mathematical software, e7u can give realistic animations of physics problems and mathematical application problems. Let Atletico see how the prism breaks down white light, how charged particles move between two electrified metal plates, and how Venus orbits the sun. As for the schematic diagram of the plane in the question, it is easy to convert it into a 3D stereoscopic image.

Because with the help of the realistic animations provided by e7u, Atletico Madrid is well aware of the details of these topics, unlike in the past, which required to use spatial imagination, and the corresponding results have also improved a lot.

Of course, his chemistry and biology grades, which were not bad, have also made great progress in the process of being able to experience them realistically at any time.

Of course, when encountering problems that are not very good at doing, Atletico still needs to painstakingly piece together the problem solving process, search the intestines and scrape the stomach to solve a few steps, and push back a few steps from the correct answer given by E7U to the question conditions to make up the solution steps, and then add the exquisite schematic diagram provided by E7U. As for the final points, he is not sure.

Even though some of the questions e7u can provide steps to solve, Atletico quickly found that these solutions are not solved at the high school level, but using university-level or high-school level algorithms, and as for whether there is a problem with doing so, you have to go back and ask the teacher.

After all, many of the conditions for high school level questions are deliberately ignored, and they are all under various "ideal conditions", and it is a bit of a feeling of killing chickens with college-level problem-solving tools, and it may also cause disgust to the marking teacher - after all, the standard answer will not provide steps to solve the problem with university knowledge, and the marking teacher needs to use his own knowledge level to manually check, which increases the workload.

The new full version of the scientific formula editor of the bee input method is a by-product of e7U after absorbing the three major mathematical software, which was originally designed to scan and identify the formulas on paper books. At that time, it was made as a simplified version of the formula editor,On the one hand, e7u can quickly scan and read the content of the physical book seen by Atletico Madrid,Later, because Atletico Madrid needs to see some Olympiad books,It was upgraded to a full version in order to identify various formulas at the university level on the Olympiad book、Algorithm,This time Atletico simply took out the two versions and put them into the update of the bee input method。

Atletico sometimes regret that the time for the math and science competitions has passed, and the person who should have won the extra points has already received the bonus points, and he will not be able to make it this year - unless he repeats his studies and then competes in a few competitions in the second half of the year. Of course, this is impossible, and he is not a stranger like "he is not from the Northern Qing Dynasty, and he is not admitted to a prestigious school".

In fact, many people who are "not admitted to prestigious schools" are not necessarily strangely only looking for a first-class university for multiple applications, and many of them are actually "professional test masters". Local education departments, local governments, and high schools usually reward students who are admitted to prestigious schools and obtain "so-and-so champions" because of political performance and face problems, usually tens of thousands of yuan.

So much so that some people who are good at the college entrance examination have discovered this "road to making money", exchanged their results for bonuses, and become "college entrance examination professionals", and some people are even happy to do it in their 30s. For the "college entrance examination majors" who can bring admission notices to local middle schools, the local education departments and high schools are acquiesced and even welcomed, as for being admitted but not going to go, wasting a prestigious school enrollment quota, it is not a problem, who made you the second place?

However, it is certain that Atletico Madrid will inevitably steal the "business" of many college entrance examination majors in the region this year.

After uploading the server version of the Bee Publisher to the Bee Secure Server, which was still very idle and running, Atletico finally shut down the computer in the Internet café where he had been hanging up for two days, said hello to the network administrator, and left the checkout.

Compared with the bee input method that has gained hundreds of thousands of users,Bee security is more miserable,Now there are only more than 3,000 downloads,More source analysis,Many people are from the bee input method website page at the bottom of the friendly link to find the bee security website,Then a small part of them downloaded the bee security 0。 9 beta.

Atletico Madrid fully understands this situation, since the bee input method is well developed, it is also good to give priority to the development of the input method. Although Bee Input did not find the person among the 300,000 users, the driver who caused the accident was sought after by Atletico Madrid.

The server version of Bee Publisher has improved the whole site download mechanism, which greatly improves the search efficiency of valuable text files, and no longer needs to download all text files at once. It also behaves more like a search engine spider.

Search engines use spiders to automatically download, index, and sort the content of various web pages on the web. When a user enters a keyword to search, the search engine searches for results from its own server's index. Therefore, no search engine can really search the whole web, they are actually just searching for the content that their own web spiders have "crawled", which naturally has a certain lag and incompleteness. So the larger the company's search engine, the easier it is to use because their indexed database is more comprehensive.

Therefore, as a global search engine giant, Google also has the world's largest number of servers, more than 450,000 units, indexing more than 8 billion web pages around the world (2005), as early as 2004, Google has saved more than 5PB of index data (1PB = 1024TB, 1TB = 1024gB).

Interestingly, most of Google's 450,000 servers are inexpensive PCs (personal computers) built with DIY accessories. Instead of using server-specific motherboards and hard disks with more stable performance and higher prices, a large number of personal computer accessories are used, so it is jokingly known as the world's largest consumer of DIY computers and a large private electricity consumer.

Of course, the stability of ordinary personal computer accessories is naturally not as good as more expensive server accessories, so Google uses a large number of backup images, and the system will automatically allocate tasks according to the load of each server, ensuring that the load of each available server is within a safe range, and timely eliminate the impact of crashes and faulty devices.

Google has designed its own three Linux-based platforms, gFs/mapReduce/BigTable/, and cleverly organized its 450,000 cheap servers to form one of the most powerful supercomputer clusters on the planet.

The gFs Google file system centralizes the index files of billions of web pages to form 64mB file blocks, which greatly simplifies the search and management of massive files through hierarchical management.

mapReduce is a C++ programming tool developed by Google for parallel operations on large-scale datasets. It schedules multiple computers to compute a task at the same time, and once one computer has a result, the other computers stop the task and move on to the next task. Because multiple computers are used for one job at the same time, the occasional downtime of individual computers will not affect the execution of the overall task.

As for BigTable, it is a system used to handle large data volumes, which is suitable for processing semi-structured data.

However, Google's server cluster, despite its strength, did not register for the world's top 500 supercomputer rankings.

The TOP500 ranking is updated once a year in June and November, and the latest data is the ranking from November last year. Atletico Madrid also visited this foreign website to see the world's fastest computers. For mobile phone users, please visit http://m.piaotian.net
