Cut hair

2007-06-18T18:22:00.000-07:00

I never touch my hair for a long time because my living without aim.

This half year , I'm still busying but nothing created or completed . At the same time ,time not stopped for waiting me -_- ~ sometimes, I could not expect to the further .

This time, i 'll back LanZhou for training the team of LanZhou office .So I cut my hair ,I want to pluck up my spirits and tidy the life of my own .

In this time .also ,i 'll spend more time for thinking the way of my future and i want to carry out the single journey when i back LanZhou .

Some friends as the same confuse as me .Any way, i think we have to deal with it by ourself .Maybe every thing will be fine measurable future~

Seven

2007-06-13T02:47:00.000-07:00

This week i went to Metro Chengdu for studying english , i hope i can promote myself on english .

It's a long time that i used "Bing" for my english name .
(It is as same as my chinese name)

but the word is not existed in the west world .

The first thing ,i gave myself a new english name .

"Seven" ——"7"

Yes, you can call me "Seven Gao" right now and i like this name .

Many people ask me the same question "why is 7, why not 8 or others."

I have no idea .just love 7 ,May the week has 7 days , May be 7 is my luck number and May the website named "CBF107" .....

^_^

so there is no reason for the name , just remember it .

ok that's all .

You'll have to share

This is from Noah's google talk message for a long while .
What's the meaning?

From 2005

We did the Ajax classes , framework via ourself.(QJAX)
We did ORM via manual .(DataObjManage)
We also did users management and rights management alone . (WTSS)
...

Right now
Ajax.net 、Nettier 、Membership can do the same thing . and these are more easy and more credibility.

Of course , I can find the same segment of ours ,but why ours' growth so slowly .

The world is open for everyone today , we must together others' idea,suggestion and different sound. Sometimes , i think we have to get others' helping .

Wow, what's i want to say ! Maybe that is the answer ~

That's all .

Some advice for Nettier or other ORM framework

2007-04-28T18:51:00.001-07:00

There are many ORM (Object Relational Mapping) framework , e.g. Nettier ,Hibernate etc

We can use them very clear for building our DB layer .and then CodeSmith can generate all of the code according to the database structure very easy.

Our going project used Nettier as DB Layer , but i in addition to another Layer named "Adapter" . VersaTran's developer can't understand the reason . so I throw my view below:

This is the Framework for our project.

Nettier DBLayer is generated via CodeSmith according to Data Base design.
Adapter wrap NettierDBLayer providers’ function and it’ll be extend other function which belong to DBLayer and can’t generate by CodeSmith.NettierDBLayer and TripTrackerAdapter will accomplish the Data Object convert to Database (ORM)
BusinessLayer will provide Business requirements for the concrete operation (e.g. budget calculate , schedule conversion)
TripTrackerUI is the package for user interfaces and bound classes, the classes will direct invoke the functions from BusinessLayer.

This is the develop workflow:

1. The UI developers work for user interface, they need be familiar with HTML, Javascript, CSS and some knowledge about UE (User Experience).

Also the developers have to know how to invoke the interface (function) which business layer provided.

(Of course, the simple, the better for the interfaces and functions)

Notice: The UI developers maybe didn’t know anything about Nettier, even what is Database, they just need know which entity and interface will be used.

2. The same as UI developers, the business layer developers will pay more attention to business realization (e.g. how to calculate budget according the condition from user entered ) , they don’t care about how to insert the data to database , they just need know which function(/interface) can store objects. (The function or interface is provided by DBLayer)

The DBLayer interface need clearly and simplify.

3. DBLayer developers must implement the objects (Entity) to database; they’ll provide the functions to business layer.

But Netter had provided the interfaces and the functions for database operations. Why we add adapter layer to gild the lily.

At present:

Simplest interface for business layer

We used Netters for interact with database, but Netters includes multiple functions, the DBLayer developer need wrap them and provide the simplest interface which business layer need.

Extend by ourselves

Also, Netters db codes can auto generated via CodeSmith, but sometimes we need ourselves functions for directly operate the database.

E.g. (We add the procedure for query by one column, which column not indicated index, pk, fk)

In addition, from the community we know the netters also have some bugs; it’s hard to say we’ll be happened. So the Adapter will help us Flexible deal with it .

See http://community.codesmithtools.com/forums/30/ShowForum.aspx for a list of 501 bugs that need to be worked around. Or here for 149 features not implemented by NetTiers http://community.codesmithtools.com/forums/31/ShowForum.aspx.

Why not add ourselves function to Nettier DBLayer:

One day we change the database structure and then auto generate the code via CodeSmith, the code maybe also not include the function we added. So the extend is better than modify.

By the way, we can’t just put our extends function on the folder (package), because the function not just a function, they live relate with the entity. (OO)

On the other hand: The UI developers and Business developers needn’t know how to implement the Database operations.

To the further

One day maybe the newest Nettier or other ORM can be done and the database operations more effective. We need promote our DBLayer .we just do the fix for Adapter and not involve Business Layer and UI.

So if you also use Nettier or others framework for your project , i suggest use a Adapter to release coupling

AJAX Thoughts from Greg

2007-02-10T21:34:00.000-08:00

This is the link (http://www.gregextreme.com/tech/ajax.aspx ) from Greg's website for AJAX Thoughts of himself ,some standpoint is so correct and some example from our project .

AJAX, previously know as a household cleaner, now is a quite common term used for web sites. We won't go into what AJAX is or the basic implementation. This is covered in multitues of articles online already. What I want to point out are ideas for smart implementation and browser compatibility. I have seen some poor implementations from so called "professional" programmers. Not saying that my ideas and/or code are perfect, I'm sure they could be better, but they have been tested to show support for common browsers such as IE6+, Firefox 0.8+, Netscape 7.0+ and Safari for Mac. They should also work for Opera 6.0+ and possibly other browsers.(Because some parts is very old ,so there are many poor implementations on our SIF project about AJAX ,Old version just support IE only ,but new version we have tested on FF and IE.)

Use AJAX when appropriate, not for everything. This may seem obvious, but I have seen people go AJAX crazy which instead of making for a more pleasurable web experience, degrades it. Let's take an example, we have a server side web page which has dynamic links based on the user's rights and two select lists also with dynamic list contents based on their rights. The web page loads, then multiple synchronous AJAX requests are sent to the web server to set up the initial web page data. This includes which links are available to the user, the items available in the select lists, even the rights the user has on the page.(The example from our project , This is the problem from SIF and Tracker. we have to spend some time to update it right now and i have to admit that crazy man is me )

In this scenario, AJAX has done absolutely nothing to improve the web experience, it has actually degraded it. Instead of waiting for the server to process a web page and send it to the client (this includes server processing for rights determination, rendering the correct links on the page and rendering the dynamic select lists) with a single request to the server, now five web requests have to be made to the server. In a LAN environment, this may be acceptable since latency is not much concern, but over a WAN connection, the combined latency for multiple web requests can become unnecessarily slow.(well, I found the problem at the same time and http://www.cbf107.com also happened the problem .I need spend more time for think the server and the client, sometime i put too much requests on client )

One touted benefit of AJAX is transferring some load from the server to the client, but in this situation the server still needs to do about the same amount of work, if not more. It still needs to process rights determination, determine the correct links for the user and determine the correct items for the select lists. The only things it doesn't have to perform is the rendering of the web page to reflect the dynamic content, however this should surely be counteracted by the lookup and processing of session information which will be required for each AJAX request.

So the moral of Part I is that for any data that the page will display which is static for the user should be loaded directly into the page, not be gotten from subsequent AJAX requests. Notice the key, "static for the user". This means the content itself can still by dynamic, but if it does not need to be changed while the user is viewing the page, it is most likely best rendered by the server.( That view is so correct,but we didn't find before )

Anyway i need spend more time for think about the client side and maybe we need reconstruction some parts.

Harry has quit working

2007-02-10T00:28:00.000-08:00

The day before yesterday ,I received the Email from Harry

We have been working together for quite a while and it is time for me leave the team. It has been a great pleasure working with the talented people like you guys. Stick to your dream and there will be a day it comes true.

Official public announcement: Harry has quit working.

From i joined WLS, many people have been Give up the job ,include Chengdu.China 's and New York State 's .

Especially Noah ,I know he is very good team leader , but he still level us ,Why ?I don't know the detail ,Jason told me reason is the view of Chengdu office ,I want to say : one reason is not enough .

Harry is my best friend on working ,we have been working together 2 years .Run back over the past ,He give my a wealth of advice , when i feel down ,i remembered he give me ring ,told me that stick by my beliefs no matter what happened and when we have a new idea or come through new product ,we were happing together.

(There are too many thing worthy of pondering ,I just want to say : Harry , I'm much obliged to you for helping us .)

Harry's Level had a great influence on my thinking,I also want to give up ,but maybe my level is not so easy .

I want to complete ZIS ,perfect SIF and the Development of chengdu office .

I think we can avouch for the quality,

I want to say :gw,cm and doro. you are very excellence,sorry to have made you go through all this.

I hope Jason make up his mind develop the product and office .we can do , please believe everyone .

...

In any case ,I'll stick to my dream and hope we are not too old when we realizing the our dream.
