Ten good practices program administrator

(1) full use of MSDN, because I personally think it is better than any one programming reference;

MSDN yes Microsoft programming information currently provided on the most comprehensive resource, it contains the latest Microsoft technology database, together with easy to use and full-text search feature that lets you quickly find anything you need technical reference data, so that you can have synchronization technology with the world elite and master the most abundant resources for program development. I have always received a lot of friends, EMAILS, their questions are often very simple, MSDN can answer these questions, but they seem not like to use to getting where I am depressed, because English is not good then or did not learn to make full use of various resources to solve the problem then?

(b) improve the standard of English, to develop more on the English website to see more information in English to buy a foreigner original English books;

the programmer level discussion with the English have too many, I personally think that to be a programmer, high enough standard of English, and even some who do not understand English, they can also become a better programmer because the development tools will be more and more a fool, but if you are only able to use a tool to meet the development of a software module that is impress the. Technical work hard studying really keen to accept a challenge programmer is not satisfied with the status quo, they always feel there are too many unknowns, so always keep learning, development of information technology is now too fast, and most of the technology the most first English version appeared at all times, and to only a few months or years later the Chinese version of the book came out, so in order to keep pace, we must strive to improve their English level, so as to synchronize to keep up with IT. You may worry about your English not, it does not matter, just start over dictionary, “All beginnings are hard\Moreover, many

English technology site than in domestic well ah! Such http://www.codeguru.com, http://www.codeproject.com, http://www.programmersheaven.com and so on.

(c) to strengthen self-management, good at self-summary analysis of their own strengths and weaknesses.

China’s leaders for more than 80% over 80% of occasions in his speech have similar views, so I was not much said here, anyway, this one with In what industry where there will not be wrong, life is their own greatest enemy is not you? manage their own clear understanding of their own, then what else fails?

(d) to develop good Document Xi Guan

programmers mostly outside like for documentation, I used to be a particularly nasty, in my the ideas of the so-called document is the number of nonsense, saying he just a dozen words Laidai Ti’s boring, As part of the Department of Chinese boys on the confession of love, it’s clear that “I love you” three words, he could force the moon ah ah sun, sea, mountains ah ah ah stone angel ah mess are linked together, even though it sounds romantic , but not practical in my opinion,:), and even Tai nauseating, and a man doing so wordy Rory’s …… good documentation of formal development process is very important part, is a good Cheng Xu design documents written before further programming, under the guidance in the design documents in order to write secure code. If you do not write the document, beginning to write programs, so you will not be the basis of the designed route to go, but think of what was where. Fortunately, that little feature, if the major function, it is easy to confusion or even loss of control. So how do you write the document then? Actually I Renwei is no uniform standard, although Guo Jia and Yi Xie NB who summed up a lot of templates, but different for each person’s habit, if you do not modify or innovation, we apply a standard, I believe would be very difficult to write and can not be clearly uncomfortable, so I think as long as you can design and implementation of algorithms, or step clearly is a good description of the document, I strongly recommend my friends in the majority of programmers to write the document to be good at using the chart to explain your thinking, we are not writers, writing may have regularly failed, handsome write articles for us, may Burongyia! good use VISIO, ROSE or other tool to express your thoughts it!

(e) coding style to standard, rigorous, higher efficiency.

this Needless to say, so we must remember! However, it sometimes may be associated with personality, and if you are a regular beard long, often forgetful button button often eat fast food often be wrong people an hour, then when you CODING be sure to pay attention to the, CODING is CODING, life is life, do not write the program is so very bad!

(6) master track debugging techniques.

trace debugger is a complicated and complex thing, so have the necessary debugging strategies and techniques Que can make these work easier up. Strongly suggest that you look at the old United States Everett N. McKay and Mike Wooding’s book , you are an uncertain benefit.

(7) develop the habit of self-tests

testing should be done by test engineers do, but you finish a module or a software, or to their own first test to ensure that low-level errors do not arise, let alone allow test engineers to see these errors, and Kuangbian your meal, you are not FACES of.

(8) good communication good at communication, in particular, often look with a number of expert learning and experience-sharing;

Some say that the character of most programmers do not like to speak within, in fact some misunderstanding, and do not like it easy for her, my head all day long, constantly turning, functions, data, algorithm ah Chongman my world, I still have time with you then talk about some boring topic , then find the right person, it easy to talk about it, the book said, “listen to Jun’s words, better than reading ten books,” you’re looking for is this suddenly see the light! now more and more to technology forums, This will be an important local exchange programmer, it was said: “Reading Jun posted a long, better than reading ten books \

knowledge to Reviewing the Old, so I suggest that programmers have to develop a phased sum up the habit of doing themes, such as you study this month or in multiple threads to do with the module or project, then After you finish, you can take to sum up all the threads associated with a number of technologies, including theoretical knowledge, practical skills and methods and a variety of excellent articles, etc., which you all kinds of capacity would be very helpful , you tried me, If not, then wait and bar!

(10) have sustained the spirit of the

This is nonsense, because I hit ten missing Therefore, it also count, like the call of China since ancient times to learn some kind of public spirit, such as Marx, Lenin, Mao Zedong, Deng Xiaoping, Lei Feng’s and so on, these spirits to make society more stable and people’s lives better, then the program What kind of spirit of the staff have? I said even if I had not, I just would like to learn any skill, it is best to have sustained the spirit of excellence, especially in some of the more abstract and more difficult to learn the technology, such as VC + +, I think it should be higher than any other development language to be difficult to learn, perhaps you have started for two years, but still feel uncomfortable did not seem to grasp what, in addition to this when you think about your learning, it also must firm belief in your goals and!

First, check the packaging is complete and correct. After a general notebook computer open the packaging, there is also the power adapter, accessories, product manuals, UNPROFOR certificate (the same code number and notebook), warranty card recording card Also, pay attention to the operating system recovery disk, installation disk if consistent with the machine’s operating system. Look, this round after round of hurdles to become very difficult to counterfeit, and so we must remember when purchasing more than a closer look!

3. Check the appearance of

check whether the appearance of the notebook touch, rubbing, scratching, cracking and other injuries, liquid crystal display (LCD) have scratches, dead pixels, ripple, screw whether Paint Falling off and so on. In the purchase should be possible to find no bad points of the machine, because the LCD on the bad points it is possible to gradually spread.

4. Check the battery

8 on top with a Camera the best;

buy a computer to know their requirements and actual affordability. Buy a computer before a clear plan on how much money to buy their own computers, as well as the use of this computer. These two points must be made clear, especially the latter, the use of different requirements, in parts of some components of the investment when purchasing a certain proportion will be more suitable for users inclined to the request, if can not buy a clear cause to the computer may not be suitable for their use, especially with computer games or design. No special practical need, do not do too great, the price of computer development is changing rapidly, not to spend too much money wasted.

2, the Internet or go to the Computer City check quote

6 memory the most Good 512, because 256 is very slow laptop;

Buy Notebook Computer Knowledge

2 to see the weight (the weight of the notebook is a very important indicator) is best 1.8KG the following;

notebook and desktop computers are not the same kind are very delicate, so service is very important. Regardless of the brand, all aspects must be considered in the notebook, how their maintenance commitments. When you purchase, pay attention to ask what these things: service and how long is, what the specific content of after-sales service, maintenance and replacement cycle is generally long. In general, notebook products to a multi-year free replacement parts, 3 year limited service-based, most of the products, maintenance and replacement cycle of 15 days. Buy notebook suggested a number of selected imported brands better after-sales service and domestic products such as IBM, Lenovo, Founder, Acer, Asus, Toshiba’s implementation of the service are very good products. And IBM introduced the blue in this regard express services, the national three-year joint protection, while in Taiwan, in the maintenance of quality and service stations to the establishment of the manufacturers there are many way to go, especially to buy just to enter the field Do find out the brand of good friends again, the issue of the money or service, pay no posting of regret.

buy Shihai must pay attention to carefully check the box of accessories within the attached, comes with the operating system and driver accessories such as whether the package instructions note the same. Also check whether there should be some giveaways, such as some brand gift bag, U disk, mouse, memory, and so on. If the product is confirmed, no problems have more to try to run the operating system is abnormal; media player audio, image is normal; MODEM / LAN Internet access is normal; cooling fan is working properly; notebook mouse positioning is normal; transformer (ADAPTER) charge is normal; fan noise is acceptable and so on. In addition, if the notebook is also equipped with a DVD drive, is also required on the DVD drive’s read the disk to be checked. If CD-RW, CD burning should be its ability to be tested. Now the company’s promotions agents compare more generally give some practical things, such as: wireless network card, bags and so on.

6. Written notice of the after-sales service commitment

10 free replacement period is long, preferably more than one year;

7 mouse touch the best;

It should be noted that the new laptop battery should be no more than 3 times higher power should not be at 3%. And generally when the dealer test machine will not insert the batteries, but directly connected to the power outlet. Charge and discharge capacity is too high or too many times that at least the machine is being used. Sony, IBM battery management software can also be seen several times the battery has sufficient power up. There is also some special detection software after we talk anymore, this must be on the spot inspection to prevent future trouble.

5. Check gift

1. check the serial number on the label

13 A key recovery and manufacturers who must learn; easy to reload your own.

3. After the decision to purchase notebook computers note

12 best machine with the serial port, Bluetooth, Gigabit Ethernet ports, wireless network card;

clear after these two need to go to the computer before the city to determine their configuration. Some related website to the configuration of computer prices, the city can go to the computer first Guangyi Xia, see if they recommend the type, to offer Internet-related inquiries and comments about the final decision to purchase the aircraft.

2. Selection of notebook special attention

1 read brand, IBM’s most solid, DELL the best value; best not to buy China-made quality a problem;

seen since tried prototype, as well as the following to do:

4 read CPU, preferably Pentium Centrino, and power;

1, define their requirements and computer use

PC Forum in Wikipedia more and the “buy notebook computer knowledge,” related article, the introduction of this article is relatively large. If you like computer knowledge, please keep in mind the only site domain name

carefully check your laptop’s serial number outside the box whether the camera body serial number of the machine in line. Camera body serial number is generally the base of the notebook body, in the check serial number is also necessary to check whether it had been altered, to be re-posted at the scene. Also, at boot time, first entered the notebook’s motherboard BIOS, check the serial number and BIOS serial number of the fuselage are the same. Three numbers are the same, the basic sources of laptop no problem, if there is an inconsistency, is no doubt that parallel or assembling goods. Formal channels to enter the domestic market, notebook computers, its official agent usually posted at the bottom there is a dedicated label, giving the product model. Such as IBM’s ThinkPad notebooks, the bottom of the machine product model and serial number, the product model for the end of the last one is C, said China. Can enjoy three years of global services, so even out of the country do not have to worry about, if not, that is parallel imports. Therefore, after the selection of books must first Zhaozhao label, on the number, otherwise the money to buy the one with the mainstream parallel, not only price losses, and also not enjoy many services. It would also be able to check online or call, more security.

2. Overpack

1. Whether to buy laptop or desktop computer to buy the brand should start from the following points:

11 Aftermarket address must be clear;

3 to see the battery, preferably 8-cell battery, can work for more than 4-5 hours is best;

A reasonable method of killing the virus

“a reasonable method of killing the virus,” is based on book knowledge, on-line information, practical experience, summed up the article, if you want to know more of these questions, please take heed virus security view includes more articles !

when you accidentally planted a computer virus, I think we first thought of killing anti-virus software must be used. Yes, with the virus is necessary to killing. However, we have neglected a very important steps. Here we describe how to Jiugei rid of the virus:

1. Disconnected from the network

if you are unfortunate enough encounter viruses after the decisive thing is to disconnect your network connection in order to avoid the virus further “spread.”

2. file backup

then is to remove carriers of the virus in e-mail, and then run the antivirus software to be removed, but in order to prevent anti-virus software, you do not have manslaughter or delete processed documents and important files infected with the virus, you should first transfer them back to other storage media that some long file names documents and unprocessed messages requires Windows, a backup, so suggest you do not quit Windows, because once the attack, may not be able to enter Windows. Whether these documents are carriers of the virus, you should back up, because some viruses are specific to an anti-virus software designed a running other documents would be destroyed, so first backup is just in case measure. End of waiting for you remove the hard disk inside the virus, come slowly back up the analysis and processing of these additional documents more secure. Another important documents you have to do a backup, preferably backed up to other mobile storage devices, such as (USB disk, mobile hard disk, DVD drive), so as not to use the local hard disk to ensure data security.

if made in peacetime (GHOST) backup, the use of image file to restore the system, so that even a potential Trojan horse is also clear, of course, this requires you to (GHOST) backup is not

3. With anti-virus software

do a good job in front of the preparatory work, then they should shut down the computer and then start the machine, and then use a clean DOS boot disk to guidance system. In addition, due to poisoning, Windows has been destroyed some of the key documents, will frequently illegal operation, so Windows, antivirus software may not run, so should be prepared under a DOS antivirus software just in case.

even be able to run Windows, antivirus software, but also try to use two or more tools to cross clear. In most cases, Windows may have to reinstall, as the virus would be destroyed as part of the file the system to slow down or appear frequently illegal operation. As the anti-virus software, when the focus in the development of different, using a different anti-virus engine, various anti-virus software has its own strengths and weaknesses, cross-use the results much more desirable.

now popular anti-virus software has been enhanced in technology, and can update the virus database, so under normal circumstances you have encountered the virus is anti-virus software should be within the scope of encirclement.

4. the safe handling

including the network login (user name, password, email, and QQ passwords), etc., to prevent hackers have invaded the course of the last to know your password. Also because a lot of after worm attack randomly send out your information, so the proper changes are necessary.

5. to prevent e-mail virus

e-mail virus, in fact, like an ordinary computer viruses, only because their main mode of transmission is through e-mail, it was only known as “e-mail the virus. ” They are generally entrained by e-mail attachment in the proliferation of methods, you run the attachment of the virus program to be able to make your computer exposure. Knowing this, we can easily take the appropriate measures to guard against. Virus is entrained in the message, the message is dead, in which the virus does not take the initiative to become alive. In general may be an attachment with a virus, you do not run it, and it certainly will not infect your system. Do not open the letters from strangers in the attachment file. When you receive a stranger claiming to be sent some of the must-read an interesting message, do not open it without thinking. In particular, for some “. Exe” sort of executable files, even more caution.

for the more familiar friend sent letters, e-mail if their entrainment in the annex, but he did not mentioned in the mail, or instructions, and do not easily run. Because some of the virus is secretly attached to get on the computer — perhaps he had been poisoned, but he himself did not know. Such as “Happy 99″ is one such virus.

to send files to others, including even electronic greeting cards, we must first confirm there is no problem after the hair, so as not to become disseminators of the virus. In addition, it should be blindly forward: some friends when the receipt of certain self think it is interesting messages, had a chance to look closely to open the address book to their friends for every one forward a copy of it was quite possible the manufacture of the virus those evil to succeed, and your friend a letter sent to you will not have doubt is undoubtedly a result, you unwittingly become the disseminators of the virus.
the general spread of the virus is through e-mail attachments in. FoxMail receive e-mail you used to see with the virus in the attachment, such as the name “Happy 99.exe” file, do not worry, do not run it, direct delete on it. Some are hidden in the Word document macro viruses, and therefore the form of Word document attachments, be careful too.

another virus to spread the use of ActiveX. Since some E-mail software such as Outlook, you can send HTML formatted e-mail, while the HTML file can contain ActiveX controls, and ActiveX, in some cases, they can have on your hard drive read and write right, and therefore with the virus in HTML format e-mail, you can browse your e-mail content is activated, but this is limited to HTML-formatted messages.

_460New Year’s Day Fishing Station jumped 10 times the 340,000 Internet users have been hit!

12 Yue 30 Ri, Rising the company issued a warning to the general Internet users, with the New Year’s Day, Spring Festival and other major festivals of the advent of horses hanging on the Internet site, fishing fish, the number of sites than the average jumped more than 10 times, the user access to these websites will be implanted in Trojan , lost his own <font style = “color: # 333 “” online games account, QQ account numbers.

Click download : Rising Kaka Internet Security Assistant 6.0

According to a malicious Web site monitoring network

Rising data provided, only the “National Train Timetable Inquiries (http://www *. touba.cn)” the fake Web site of the recent invasion of the nearly 34 million Internet users. The pseudo-Google search engine, websites, fake lottery tickets every day invasion of the number of tens of thousands of users.

is this fake website, so that 340,000 User fooled

Rising security experts said, whenever the National Day, New Year, Chinese New Year, Christmas, such a large holiday approaching, users who will increase Network usage, such as through the Internet to check the train lines and the fares to find their own plug-ins and other online games of interest. A hacker is targeting Internet users of this psychology, the establishment of a large number of fake Web site, through the SEO (search engine optimization) techniques to improve their rankings in search engines when users search the contents of their own interest, these sites will be carriers of the virus top surface, users are unknowingly on the “right time” the.

So, how to prevent ordinary users should be pegged to the growing surge of horse web sites and phishing site?

Rising security experts recommend: First, make up for vulnerabilities, the recent IE Vulnerability (MS08-078) the threat is very serious, every day 70,80 million users hit by this vulnerability. Install the free Rising Kaka 6.0 (download), use one of the “vulnerability scanning and restoration,” we can give PC to lay all the patches.

second, you should install a new version of Rising 2009, etc. antivirus software , its unique “Trojan invasion of blocking” function can block hang Ma Web site with a Trojan horse. When Internet users visit a Web page linked horse, Rising 2009 immediately prompted to malicious Web page code, and displays the name of the virus.

Third, Internet users through the search engines to find information, should be especially careful not regulated by the composition of the CN class alphanumeric URL, such as http:// *. baiduduyou4.cn /, http:/ ** . bai6ud.cn, these sites are likely to contain viruses.

Digital Cameras Input language skills

with a digital camera for fast text entry, it is very simple and is made into a photo spread into the computer, and then recognition software to convert plain text file format can be.

Whenever your boss throw a thick stack of files, so you are typing a word for word the computer, do you feel is not going to collapse? Have you ever thought, a digital camera you can make it better and more economical to “typist”?

Today, digital cameras have large numbers into ordinary homes. For ordinary users, the use of digital cameras to shoot photos, it is only right and proper thing. However, with digital cameras to input text, I am afraid that most people in the eyes of a little fantasy. Now, let’s first look at the Du Men capacity unique skills – with digital cameras to input the text of the real “Kung Fu Hustle.”

shooting

with a 300-million or more pixels, more than 3 times optical zoom digital camera that filmed the original manuscript. When shooting should note: the manuscript should be flat, the camera should end flat, light to gentle uniform. Can scatter light in the corridor or window, the three primary colors can also be taken under fluorescent lamp eye protection.

taken correctly identify clearly the key to the later, 300 million or more pixels can guarantee for identification after shooting the text is large enough; 3 times optical zoom when shooting so that the manuscript in each of lines covered the screen. I have been comparing the 300-megapixel shot than shooting with 2 million pixels recognition rate is significantly higher.

Do not use flash, light is too strong, shot down but the writing is not clear.

conversion

in the computer’s hard drive to create a folder, the photographed images into one. However, these images contrast is very small, the entire screen is gray; and a variety of digital camera image format is different, OCR software (OCR software) may not be able to support, so we are advised to use ACDSee or Windows built-in “Paint & rdquo ; program conversion.

writer is a Windows comes with the “Paint” program to convert the. First, the order click on “Paint → File → Open” in the “Look In” to find the pictures, open and click “Save As” in the “Save as type” Select ” monochrome bitmap. ”

Click “Save\Converted obtained new pictures follow the original name, changing the extension to “. Bmp\

identification

run OCR software (which can be downloaded from the Internet, the author uses Tsinghua TH-OCR2000 Millennium Professional Edition), then click “File → Open” in the “Look” and find your pictures. Click on “order” drop-down menu appears, if the need for full recognition, you can click on “all recognition\The upper part of the software window after shooting, the converted original image, the lower part of the text is identified. Recognition followed automatically created after the original name of the txt file, saved in the original file folder.

If only identify part of the text, press and hold the left mouse button in the need to identify parts of the text pulled out the box, there a yellow block, click on “identification” can be.

finishing

created at the beginning of the file folder to find the extension txt plain text file file, this is the information needed for identifying the wrong word to modify, especially in the text emphasis added and underlined text recognition rate is still relatively low. At the same time in the file folder, there are many extensions chr, trc, sim files, which are generated when OCR recognition temporary files can be deleted.

Vista System Security Model Application Skills

have some understanding of computer users, security model will certainly not unfamiliar with this.
