Measured: the single-core CPU computer to install Win7?

My computer the previous dual-core main board is broken, repair, and temporarily bought a 754 computer. The computer configuration is as follows:
The SP2600 + of OC 2.3G
Jetway K8F7P
South Asia 512M DDR460 X2,
with the side disassemble 7300SE
WD640AAKS
DVD burning
ACER UM08A51 battery
ApeXi the MOD Ver2.05 # 3 X-Fi Platinum Fatal1ty Champion, the Series the
Swans D1080MKII old version
Flico N-Key Rollover tea axis
WACOM BAMBOO drawing board
Toshiba AC Adapters
Logitech V470
Computer configured to run Windows XP is still very smooth, but has been accustomed to win7 , wanted to try it in win7. Complete flagship version of this configuration you want installed and running fast is not possible, then install the Professional Edition ( Win7 pure version of the system to download, including 32 of the 64 Ultimate Edition / Professional Edition / Home Premium ), the installation is complete and then optimize less process, system service before the final results are as follows, this is at the expense of the necessary function (such as the internet to share Internet access, dhcp function, etc.). 33 process had to include anti-virus software, X-Fi sound card driver, the relevant procedures to the drawing board, the GDI + +.
Memory usage is not high, but look to see the cpu it, this is my little computer laptop battery operation, cut out of the chart, that curve is really quite ugly. Daily use, such as browsing the web, such as general physical memory usage rate of 60% or more, but if open the largest software will rise even higher. cpu slow is the main reason in the crazy Maximize and minimize windows process, cpu high usage rate reached nearly 100%. Look at the single-core install win7 ratings.
Score looks okay, the other one is not on the score compared to my laptop to see it:
The notebook is installed Win7 Ultimate score contrast, in addition to memory scores slightly higher (after all, this is DDR2 667), the other scores of one than the desktop. However, the notebook run significantly since win7 are comparing the single-core installed Win7 computer fluency many, many, or the full effects. Continue to be crazy when switching windows, the cpu high usage rate is only about 40%. Notebook actual running win7 speed is less than it runs xp. Just a lot better feeling in the fluency.
In summary, this configuration a single core CPU desktop computer to install win7 at most can be used on the Internet, used to dry the other thing really is not easy. While the other netbooks it, atom +945 also higher than the desktop machine, I see it running win7 game is so fast, certainly less than the speed of xp.

MySQL database optimization and logic optimization techniques summary

I learned the MySQL database optimization, just used in the project, and cross-chapter document, and share with you. Prior to study large-scale projects caching system memcached useless learning java security.
First, the MySQL optimizer
1, the use of the index
Database index the query is very fast, MySQL, query-based index of the B + D, 500 000 records only need four times the query will be able to navigate to be diverted. Therefore, the establishment of a suitable index is very necessary, and you can see the pros and cons of indexing through the system of records.
See the results (number of operations per second) by the command show GLOBAL the status like 'the Com%';
Can be seen that query, modify small, appropriate indexing
2, to optimize the SQL query
2.1 slow query
Query a lot, so to speed up the search habits of users is two to three seconds would like to see the results, so we will slow the query time is set to 1s, and recorded the statement of all slow queries and detailed information for analysis and optimization.
Set the following settings in the file / etc / mysql / my.cnf
log-slow-queries = / var / lib / mysql / slowquery.log
long_query_time = 1
Check out the MySQL record log is as follows:
mysqld, Version: 5.0.51a-3ubuntu5.8-log ((Ubuntu)). started with:
the Tcp port: 3306 Unix socket: / var / run / mysqld / mysqld.sock
the Time Id the Command Argument
# Time: 11:15 120 228 : # Query_time, 01
# User _AT_ Host: root [root] [10.11.18.38]
: 43 Lock_time: 0 Rows_sent: 0 Rows_examined: 0
use tvmarket; the SELECT A.App_ID, A.LogoUrl, A.UploadTime, H.ScreenShotUrl the FROM T_App A, B, T_App_Info, T_Dev the F, H-T_App_Screen_Shot, T_App_Type_PK D T_App_Type C, where A.UploadTime "20,120,221,160,603" order by A.UploadTime desc; # Time: 120 228 11:24:59 # User _AT_ Host: root [root] [10.11.18.38] the the # Query_time: 203 Lock_time: 0 Rows_sent: 0 Rows_examined: 0 SELECT A.App_ID, A.LogoUrl, A.UploadTime, B.AppName, C.TypeName, H.ScreenShotUrl, F.Score FROM T_App A, , T_App_Info B, T_Dev F, T_App_Screen_Shot H, T_App_Type_PK D, T_App_Type C where A.UploadTime> "20120221160603" order by A.UploadTime desc;
It can be seen that these two queries are very slow, so you can lock the statement to make changes and optimize.
Section 2.2 of SQL optimization
2.2.1 go to sort the files
Explain + SQL statement, and Extend, + SQL table join order of execution of SQL statements, acer laptop battery connection, whether the index is used, the need for full table scans and intermediate temporary table and file sorting information.
File sort is the slowest, to sort the files must be removed, and try to remove the full table scan, analyze the SQL statements SQL purpose: check the ID of the developer application to query all of the developers state the number of EXPLAIN SELECT COUNT (APP_ID) AS NUM, State FROM T_App WHERE DEV_ID = 1484 GROUP BY State results:
The above SQL statement is used to sort the files, optimized SQL statement
SELECT COUNT (APP_ID) AS NUM, State FROM T_App WHERE DEV_ID = 1 484 the GROUP BY, the State  the ORDER BY NULL;
The results of the analysis, removing
Similarly, as long as it is to use SQL aggregate functions and grouped the MySQL default you want to sort the files, just add an ORDER BY, NULL is you can not sort a some sort would not have added, such as grouping the results of the sort of time.
2.2.2 go to full table scan
Some full table scan is necessary, but only need to query a condition is met by adding the LIMIT 1 to eliminate full table scan.
2.2.3 try to remove the SELECT *
Second, the logic optimization
To determine the registration of a user when the mailbox has been used. Dell Inspiron 6400 battery.Faulty logic : E-mail and query all registered mailbox comparison. The correct logic : According to the mailbox to a database table query whether to return results.
Insert a record to determine the successful insertion of the wrong logic : go check records to determine returns the result is empty. Correct logic : return to the results of the inserted record is true or false can be.
Postscript: This is just part of the optimization is relatively simple and common approach, and more Reference: MySQL 5.1 Reference Manual - Optimization.

China’s strategic focus to display Google ads

SAN FRANCISCO September 15 pm news, Google China has experienced silence found a new excitement. Google's global vice president John Liu said, the multinational giant in China's Internet advertising sales and new product development strategy is undergoing changes.

Search advertising into display ads instead of focusing

In March last year, Google China will search web pages and pictures on the move to google.com.hk, business development into the trough. John Liu told ZDNet today's interview, revisits this special experience. He said that last year, has been seeking stability, and to explore the future direction of the problem until the second half, and finally feel there are many things you can do. "Although the search has been limited, but display ads, there is a great mobile advertising ACER AS10B31 Battery market."

The so-called display ads, Google will be defined as all non-search advertising, from text, video and rich media to the mobile terminal, the size of its global industry has reached 200-250 million, a figure expected to grow to the next 200 billion per year dollars.

John Liu said, Google's display advertising business in China last year made a "very encouraging" growth. He disclosed the data in 2010, Google China's top 100 advertisers, 97% are put on display ads, the top 50 advertisers ad spend last year's show there have been doubled up. John Liu said, China this year, Google is to determine the "steady search, display advertising and mobile advertising to strengthen" strategic direction, the company "The whole team are in the excited state."

"Display advertising search advertising market potential is actually much larger than the present site display ads to banner, text, rich media, mainly in the form, now has added new technologies and products, such as the video field, the mobile space from the trend point of view, the search advertising to display ads will gradually shift, and a couple of years the market capacity will reach 200 billion dollar industry. "John Liu stressed.

From a larger background, the business also benefited from the direction of global resources and experience to Google. Google China is also important to many products such as Admob mobile advertising platform, ADExchange trading systems to integrate the search for greater growth.

Redefine the "localization"

And advertising sales strategy to adjust simultaneously, as well as Google's China R & D strategy changes.

Recently, Google quietly on the line, called China "the benefits" of the buy navigation search product, the run on the localization of products on the google.cn, many a time led to speculation that the industry has even been interpreted as Google to return to their mainland market signals.

John Liu told ZDNet today unveiled the interview answers: this is "a very early test version of the project", do not Google in China, especially the local product, just Google search field in the shopping world a try. He explained that currently are pushing Google's global business based business, try new ways to integrate shopping search function, is the world united in doing.

John Liu further noted that the Internet products should not be introduced for a specific country, localization should not be specifically developed for the local product. His latest social product with Google Google + For example, the introduction of the globalization of community service under the premise of participation by the local companies to enhance the user experience and improve service quality Acer Aspire 5315 Battery 4800mah, Google is the definition of localization. "The launch of global harmonization of product, then the user experience and enhance the cultural localization, which is the trend."

The Google China R & D system is more than a year since the most important changes occurred.

Google to enter China in the beginning, he strongly promote the "localization" strategy, and actively develop the local market characteristics in line with China's unique products and services. But clearly, this strategy has now undergone a fundamental change. John Liu said, China is currently Google's engineering team has been integrated into the global product development system, and local participation in these products enhance the user experience work.

"We are multinational companies in China have a unique value, they should do something better to lead the technological innovation and continuous learning," said John Liu.

Leading enterprises will become the beneficiaries of

Hualong Securities analyst Peng Jian to Tencent Finance, said the lead-acid battery industry's leading enterprises of the industry consolidation is good, because no change in the overall market demand, but supply would diminish, so prices will rise. Thus, to meet the environmental standards for listed companies but rather good news.

Peng Jian pointed out that the ministry is not easy to meet the requirements, only the large enterprises have financial resources to re-buy to move plants.

Late June, some small and medium enterprises increased battery products ex-factory price, followed by large-scale enterprise product lead-acid batteries with the ex-factory price also rose by 10-15%. Securities, reports that the feedback from the current market situation, the problem is not just price, but also because of lead-acid battery has a price not available.

Analyst who asked not to be named, said lead-acid battery industry is a "sunset industry", has been gradually declining, rare in full-time broker research departments to study the industry personnel.

As a substitute for lead-acid batteries, lithium Laptop Battery development was good, but the problem of high costs has not been resolved. For example, an electric bike is currently on the market price of 1,300 yuan, while the use of lithium Laptop Batteries for electric bikes sold for $ 2500, nearly doubled. Peng Jian pointed out that the problem of high cost, lead-acid batteries to replace lithium batteries in 5-10 years is not easy to appear.

Huatai Securities research report also said that although in the process have greater toxicity, but the lead-acid batteries with low-cost, high-capacity, secure and reliable high-power and features are still widely used in industry, in particular the field of automotive starting batteries, and in a certain period of time is difficult to replace by other battery technologies.

Ever tightening environmental regulation of listed companies

The Ministry of Environmental Protection released the first lead-acid battery business is open to the public, a type of polluting enterprises of all information. Lead-acid ACER laptop battery listed companies implicated by the environmental protection department reorganization, share prices fell, companies seem to be a reflection of increasingly tightened environmental regulation.

Back in the first half of 2008, the ministry and the SFC issued "on the strengthening of environmental supervision and management of listed companies, the guidance" and "heavy polluting industries on production and management company IPO application filing, "which officially launched the" Listing environmental review "system.

According to regulations, in metallurgy, iron and steel industry in 13 heavily polluting enterprises in the market, they must get the green "ticket" - listed by the Ministry of Environmental Protection environmental review HP Compaq AC Adapters, otherwise, the Commission will not accept the listing application.

It is understood that listed the company's environmental problems, especially after the listing of environmental regulation, will be the next "green securities" policy breakthrough. Lead-acid battery industry consolidation can be said that this provides a good model.

Industry reshuffle of Lead-acid batteries

Lead-acid batteries are mainly used in power, backup and storage, according to the distribution, more concentrated domestic bases are concentrated in several large batteries, Changxing, Zhejiang, Hebei Baoding, Guangdong Pearl River Delta, Fujian Quanzhou, Jiyuan, Henan, Jiangsu, Jiangsu, Shandong Shandong Peninsula .

According to Ministry of Environmental Protection issued August 2, notice that the review of 1930 by lead-acid battery companies, enterprises engaged in the production of battery 639, a simple assembly of business 1105, the remaining 186 are recycling companies, which have a total of only 252 companies continue to produce, and another 80 plants are still under construction, check the production line by means of "death" more than 80%.

This year, Zhejiang, Guangdong and other places of frequent blood lead poisoning cases, lead-acid battery industry attracted to the strong concern that the industry has become this year's environmental remediation special action priority.

March 2011, the Environmental Protection Ministry, National Development and Reform Commission and other nine departments of the State Council jointly issued "on the 2011 depth illegal sewage remediation company to protect public health and environmental protection special action notice" (UNCED [2011] No. 41), will lead battery business regulation as in 2011 the primary task of environmental protection special action, called for lead-acid battery industry to conduct a thorough investigation business, a comprehensive remediation of environmental law issues.

According to Asia laptop batteries Association, China's domestic lead-acid battery market from 54.0 million in 2005 increased to 2010 kVA 166.5 million kVA, the annual compound growth rate of 25.26%, to become the world's largest producer of lead-acid batteries, 2015 lead-acid battery production value will reach $ 70 billion.

On the other hand, the current level of domestic lead-acid battery manufacturers vary greatly in the world's most advanced production lines, and some are still hand-craft workshop-style backward, less than 200 above-scale enterprises, small businesses accounted for 90% above.

Chinatrust Securities research report through that short-term shutdown, the supply for the industry has little effect, because most companies have inventory, but the long term, the elimination of small and medium enterprises, will lead to further increase industry concentration.
