UML in practice, the current situation and some of the recommendations [2]



The fourth problem is the small number of programmers rely heavily on automatic code generation framework, which is in fact the key issue is not UML. In order to use certain tools they generated is not consistent with the code reading habits of Chinese people, willing to give up everything else. UML for them is just a code generation tool only, so they make the most of little value UML, more formal.

The fifth problem is that project resources. Most of the projects the domestic real resources available are very limited, if the foreign company to other developers to see whether the development cycle or human capital are basically ridiculous. UML should actually run through, not only in the initial design stage, it should run through the entire project team, including design, management, development, testing, everyone should use it.

I think in general the company if not sure do not have too much blind faith in UML / RUP, in fact some of the items do not need-based lightweight RUP or UML. UML is now intend to study with colleagues, it is also possible to first lay down the future, there will be more outstanding technology to replace it, now take the time to learn and practice as much about OO design, something more basic. In fact, just familiarize yourself with the tools and the exchange paradigm, the future for you, just a few days to a month or something, do not care much about. For those who now have decided UML actual project to be successful, my suggestion is as follows:

First, the project cycle at least plan to extend the usual 50% to 100%. You must follow all explained that the only way to make a meaningful UML itself, can effectively improve the quality of project design.

Second, the project began to focus for a period of UML development training. Consistently throughout the project, to be regular all-round exchange of object-oriented design (of course is a combination of UML), the attempt to improve design quality through the exchange.

Third, customers and the company leadership withstand the pressure to put as many design problems to solve in the initial design stage, rather than be forced to rush to complete formalism of UML design, and then cast aside the design and began coding.

Fourth, properly handle the part of the "elite" programmers resistance. To divert the flow, can not be diverted should be considered even subdue him completely out of the project group,. UML magnitude of team development does not encourage individual heroism, no less than cruel to simply not go forward.

Fifth, not too high expectations on the project. Eager acceptance of both the face of higher credit to the government clients, or companies only know how to act recklessly not understand technology leadership, must keep a low profile, it is not necessarily an immediate impact as an experiment ... ...

Well, to write so many, Good luck.

Figure 2 collected the most popular nowadays are symbols

Input plug surprise 2: Super Multi Text enhanced modification tool

Text input, if the re-modified with its rendering, you can put QQ signature or a number of forums, the effect is absolutely stunning. Like what line of characters, dot matrix characters, Shu Xie ancient writing. To show these forms of words we often see other people use, if they want to use words is generally the most stupid copy modification method, which becomes their own, but this method is not only cumbersome but also the revised text does not neat.

Mars, built a lot of text input text form this converter can convert normal text arranged in the form of various shapes and sizes.

Shared experience of domestic boutique Foxmail 5.0 (multi-map)


Foxmail 5.0 can be described as "long-awaited" would have broad company said its developer is published by the end of July, but was postponed due to various reasons, they have a month. During this period only in the Sina Web users see a "Foxmail 5.0 Alpha 3 full trial reports are not" test version of the Internet do not see any sign of, really tempt the appetite of the users. However, the breadth of the company means what it says finally, in August of last day of the last joint Sina released Foxmail 5.0 Beta1 version of the following, we would soon see what new changes the new version now!

Still friendly user interface

If your system has been installed the old version of Foxmail, then the implementation of Foxmail 5.0 installation Cheng Xu O'clock, Ji Tong will be prompted whether to upgrade, select "yes" in the new version Jixubaoliu Yuan Lai's accounts, address books.

In general terms, Foxmail 5.0 user interface and does not have much of the change (Figure 1), still maintained a light and breezy style, but XP 32-bit true color characteristics of the icon is likely to make you brighten.



Figure 1 Foxmail 5.0 user interface

Shut out spam

Foxmail 5.0 enhanced anti-spam features in particular, the use of the Bayesian algorithm, rule filtering, blacklists, white lists and so on filtering technology that can accurately identify spam and non-spam.

Foxmail 5.0 blacklist used to record the address to send spam or name of the sender of the message if a new address or name is included in the blacklist, then this message will be determined as spam and moved to "scrap box "in. The white list is used to record will not send junk mail to your address or name of the sender, if the sender's address included in the white list, then the message will be directly determined as non-spam.

If the e-mail address is neither in the blacklist, nor in the white list, then Foxmail 5.0 will continue to use the "Filter Rules of Law" on the e-mail to judge, each corresponding to a fraction of spam rules, when the message matches a rule, the system will message corresponding to the increase in the score, when the message when the score reaches a certain value, will be judged to be spam.

Finally, the system will use the "Bayesian algorithm" on the e-mail to judge, but before you need to let Foxmail study group spam and non-spam. From the "Tools" menu, open the "anti-spam settings", select "Bayesian filtering" option page (Figure 2), click on "learn" button, the message will pop up study guide, select one to learn E-mail, select an appropriate option to start learning. Purpose of the study is to collect the mail features of words, this thesaurus can be automatically generated waste and non-spam lexicon, when discrimination based on "junk words" and "non-spam words" appear frequently in the message as a condition, even if the user not set any rules, Foxmail 5.0 automatically after learning antispam.



Figure 2 uses "Bayesian filtering"

Make your e-mail more secure

On business activities, to ensure the authenticity of the message (not imitation by others, or deletion) and confidentiality (or illegally intercepted by others here) is becoming increasingly important. Foxmail 5.0 can be digitally signed and encrypted messages, compatible with a variety of encryption and decryption algorithms, much convenient for users.

To use the digital signature, first need to log http://ca.foxmail.com.cn broad application provided free of digital certificates, the entire process including the installation of CA root certificate, apply for the certificate, obtain the serial number and password, download and install the certificate. When installed, open the "Tools 鈫?System Settings 鈫?Security" tab page (Figure 3), where you can set whether the contents of all outgoing messages and attachments be encrypted, whether the signature on all outgoing messages and so on.

If you want to send a signed message, as long as the new message window, click the toolbar's "signature" button; send encrypted mail, click on the toolbar as "encryption" button. Read the digital signature or encrypted message, you will find a ribbon marker or lock tag, if there is to read the e-mail security issues, such as e-mail has been tampered with or the sender's digital certificate has expired, Foxmail 5.0 will display a security warning message , and specify the problem.



Figure 3 Setting the digital signature

Web Mail messages received

Homail, MSN, Yahoo and other mail, Web Mail provided only the means of receipt without providing POP3 collection methods. Previous Foxmail 4.2 have support for MSN Hotmail and send and receive mail, but for Yahoo's mail, they can only receive mail from Yahoo.com.cn, but also must agree to receive advertising terms. Now Foxmail 5.0 can not only receive mail from Yahoo.com.cn, but also the normal charge from Yahoo.com posting it! This is the advantage of Foxmail-Hotmail Proxy technology to achieve, if Foxmail-Hotmail Proxy program running on the local machine, then the "POP3 server" field only need to fill "localhost" can be (Figure 4).

Figure 4 Note that login name to use E-mail address with the registered name to use

Unfortunately, at present we are still only receive mail from Yahoo.com e-mail, mail can not send mail using Yahoo.com, can only function of the EMS.

In addition, perhaps because it is a test version of the reason, Foxmail 5.0 being the way also can not receive IMAP mail, hope to join the official version of the launch of this feature.

Other new features

Import other mail system's address book

Now we can import in Foxmail 5.0 Outlook or OE in the contact list, address book, or even Netscape Mail 3.x and Eudora 3.x in the Address Book can import. The vCard feature can help users achieve PDA, cell phone, the remote server and other equipment and Foxmail address book data exchange between.

Support the electronic business card



Figure 5 Editing a vCard card

VCard electronic business card format is the contact information, vCard format can be widely used in various digital devices and operating systems, as long as the advance in the "Account Properties 鈫?send a message" in the edited your card (Figure 5), after writing a message can be inserted at any time on it. You can use business card information and contact details of the sender's public key digital certificate to send to each other. The other received message will contain a suffix named ". Vcf" attachment, the attachment is vCard card, double-click it the system will open the Microsoft Outlook program displays the appropriate card information.

C # Learning Notes (April 3)


Public type system (Common Type System) built a set of data types, provide. NET languages define variables, use variables, management variables type of common rules.

C # type can be divided into two categories: one is a real value type (Value Type), configured in the stack (stack) which is always not as null; and those for the reference type (Reference Type), configure them in the Managed Heap . C # is type-safe language, is not allowed to use the variable before the variable initialization.

Learn C # and the relevance of operands is important priorities, contribute to the operation of the process of writing applications, and application debugging.

Use conversion operation can be clearly the number of the type into another type, but the conversion to note whether an overflow issues in order to allow programs to a more stable implementation.

C # provides a number of statements can be used to control program flow. Common choice statements: if, switch to a specific value or statement to decide whether or not the implementation code. Repeat statement: such as while, do, for, foreach can repeat a section of code several times. Jump statements: like goto, break, continue, etc., used to control the conversion process.

To be more stable applications implemented in the programming will have to be careful when handling an exception error, in order to avoid the user in operation due to unexpected movements such as opening a file does not exist, the encounter program infinite loop problem. When the C # application program execution when an error occurs, the system generates an exception error, you can use in C #, try ... catch catch the error and prompts the user instructions appropriate information. If the system error handler can not meet the needs of programmers can write their own inherited class System.Exception exception type.

using System; class Method (public static void MyMethod () (Console.WriteLine ("This is a method (Method) is nothing but a bunch of C # code in the set."); Console.WriteLine ("method in a different language different names: such as functions, subroutines, etc. ");) public static int Main () (Console.WriteLine (" This is a method, Main, WriteLine and MyMethod are three ways this code "); MyMethod (); Return 0;))
In C # all the way to a member of a class, which allows other global functions, global vice procedure programming language (such as C, C + +, VB, etc.), not the same place.

Additional team bonus, energy stimulate team


For the marketing team to set the salary system has been discussed for many businesses and headache. If you set a good, you can play a small but powerful chain of effects; if the set is not good, then make the team lifeless, unable to inspire the team dynamic. Now many companies marketing team to set the salary system is generally base salary plus bonus or commission, the basic salary is fixed, while the bonus and commission rate of or are based on sales or profits to reach the floating state. and bonus calculations are set according to some formula, the higher non- the right to determine the distribution of lower bonuses. This is just the hardware evaluation of the marketing team, while the team's cohesion. discipline. team building. execution so they can not use money in the form of assessment. and so it was a blind spot of the assessment team.
So how in the form of bonus marketing team at the same time evaluation of hardware and software, the maximum excitation team dynamic? I believe that the marketing team can effectively set up the team prize to solve this problem. Specifically as follows:
1. Establish the marketing team in various positions in the base of the team bonuses, such as 500 yuan, director of marketing; marketing manager for 400 yuan; marketing director or the Office of the Director of 300 yuan; marketers 200 yuan.
2. Determine the marketing team of software assessment indicators.
3. All the hardware assessment targets marketers pay staff bonuses based on the formula, but the team bonus pay not to be directly calculated.
4. After the end of monthly appraisal software by a higher index based on lower-level team to determine the distribution of bonuses, and pay staff salaries. Should be emphasized that higher levels can only determine the distribution of direct subordinates of the team prize, not leapfrog distribution. Such as marketing general manager only director of marketing team can determine the distribution of bonus, but can not determine distribution, marketing manager of the team bonuses, and so on.
Note: 1. Bonus percentage of total team prize too hard to 5% to 15% more appropriate. If the ratio is too large, it will lead marketers money floating base is too large, is not conducive to marketing team stable and prone to fraud and bribery marketing management phenomena, but the ratio is not easy too low, the ratio is too low there will not achieve the purpose of the assessment team of software.
2. Despite the higher level team can leapfrog to the distribution of bonuses, but the monitor has a responsibility and obligation, once the lower levels found lower in the distribution of bonus among the team of serious anomaly should be ordered to lower-level explanation and correction.
3. To avoid the marketing managers in the allocation of bonuses to team appeared''to do good "for the average distribution of the phenomenon.
This bonus can also be used to set system to other departments, specific methods and issues can refer to the above methods and issues.
