I have enjoyed pair programming several times and every each- was fine. The analyst/PM knew What and I knew How and WHere. We by comments wrote the algortihm and than we developed each step and resolved or reported exceptions. One question to our customer caused two day o fdiscussions.

If you can share the screen even leave a control you can do pair programming too.

But take the pair programming as a basic work method is not wise.

Good to publish such features. They are known. But I am surprissed autoboxed ints and Integer are not cached togehter.

Thank you. I have several months experience only.

Hi, why "using WiredTiger may not be ideal for most of the applications" ?

Good/bad - I think you have some tools and you can choose the most useful by purpose, conditions, traffic....

When I need implement the object equality comparision so I must naturally implement the business-defined equality in all used interfaces + hashCode().
Thank you for reminder and example - I wrote "naturally" and I made this bug last month.
Keep attention using method generators.

Pair programming is useful but not the main streaqm...

How I wrote on http://java.dzone.com/articles/agile-decompiled-pair : <br/>

Each tool is useful under specific conditions. <br/>

I have enjoyed pair programming many times: one with the global knowledge of the business domain and I created the algorithm during a discussion (it was such a brainstorming), I wrote it as a comment and then we implemented it. We both added some ideas, detected a difficulty or alternative flow, error possibility and I had a technology knowledge. I have enjoyed it in vice versa roles. <br/>

But generally we were using it for specific tasks. <br/>

Hi,
I thought the same idea reading the Heisnberg Developers article here .

The next interesting term of physics is the inertia concept. You can notice it in the human behaviour, system reaction after action, nature environment, social structures, business, trade....

Great. our book is so old and we will not upgrade it..

Both, the technology (code writting) and Problem domain are amusing, I think. Each problem will grow when you deal more deeply with it. I began in the machine-industry factory. We cover these areas: salaries, material supply, human resources, accounting, production-preparing etc.

We assembled a product (lift truck, excavator, belt conveyers, etc.) tree of piece lists, collected material requirements, costs, durations, selected material by used technology operations. On mainframe of BM 360 class in 1980s. Very interesting job and amusing.

When I changed my job I thought register of contract, collect payments - such a boring topic! During years I noticed many interesting tasks I had to realize. Keep history of all data, simulations, big data amounts, notifying other modules.

Problem domain is interesting. The customer knows his kind of view, sometimes vaguely, sometimes detailed extremes, BPs in his firm. The analyst knows overview and details of ERP usage and implementation. The programmer knows a technology realization. What is more difficult? It depends on your skills and abilities.

Problem domain knowledge is structured overview with details and dependencies, edge conditions, secondary effects of changes. It is something built through years and hard work. It is kind of a treasure...

I don't like multiple exit points of method. Excluding such a called "early quit" (see examples given by others) which is labeled by visible comment "quit ----"

If you deal with 5-lines method with one if or switch may be. But like missing block brackets are wrong by later updates so you can break that methods two years later.

I like your algorithm serie.

One note for newbe: When insert and delete (especialy the first or last item) and path through is most heavily used then use linked list. When you need access to i-th item use array list.

For the real usage: if you do not use any library and implement your list create list and inner item separately from the business class (Person).

Could you note the list can be cyclic with stop-head-end node? You do not need to expose the cycle outside.

Hi, great serie! If you want watch these algorithm running see into JDK Sort Demo in jdk-install-dir\demo\applets\SortDemo\example1.html
or http://www.cs.ubc.ca/~harrison/Java/index.html and
http://people.cs.ubc.ca/~harrison/Java/sorting-demo.html
originally created by James Gosling and modified by Jason Harrison and Jim Boritz. Soon will be available some example application :-).

Hi, great! What engine, scene structures and 3D renderer do you use? Milos

Lazy people are source of evolution and development. If I don't want do something I think out and I will invent something what helps us.

Hi. For non-programmers-people: programmers are very hard working :-).
For all: Programmers are lazy in that meaning - they hate do the same work twice, they hate useless or boring or repeated work. The programmer (as a mathematician) thinks a half hour to spare time, typing or to make things more smart/elegant/beautiful. "Coding faster" is a trip to hell. May be typing faste.

Keith and co.: If you do not have any hobby you are sad poor little boy. There are many reasons to do any hobby - pleasant happy hours, amusing and enjoyable work. Somebody climbs mountains, somebody makes models (train, planes...), others dance..... Everybody is original and does what is enjoyable for him, e.g. wallow around like a pig on the sofa at TV by stupid program. I like programming per se. It is amusing, I enjoy it. Most of the time at my work I do programs that are not interesting problem to solve by very old technology. SQL is not my favorable language. The time is problem. And procrastination kills all plans. Bye I must do something useful!

Hi, one principle of XP is : take only what works. It is clever use the golden middle way (from Czech language). 100 % pair programming is not effective. When you go to trip you use little car or the bus for a group. WHen you want to bring bricks or sand you use a truck. Pair programming is useful - cases described by the article - the analyst knows what and the programmer knows how. Then the cooperation is a synergy. - when you need any dr. Watson to explain your problem.

Hi, I created a prototype of our information system two years ago. I had four, five days free. I had similar autentification/authorization module - it was general and looked up for service that loads Users, Roles, Permissions, password encrypting according to brand. Some customers could want to join to their system of autentification, they can have own tables or libraries for it. I have been still interested in it. I have several questions for discussion: - How to ensure the right implementation is installed and is returned the first or only. It is not suffitient to sign the module only. - Has somebody resolved safe license checking? - What do you think about java.security.Permission class usage? I had Permission in tree structure build by roles and groups. Milos

Why the Formatter way " creates less objects" ? I create StringBuilder or the Formatter - its one. The Formatter has its inner buffer for string/char[] manipulation intuitively. If you have a look into Formatter source you see it uses StringBuilder - so you create two objects. I do not know sbuilder.append("one", "two");

Why do not name their public interface ResourceAccessor When you write class code you better remember that S is source, R result and A argument. This is reason why Map is defined as Map and not Map. I remember an antique times we have to use one-letter variables only.

I use hint Assign Return Value To New Variable

I place the cursor on method call and wait to hints.

This hint creates the declaration, variable and assignment.

In this time nobody argues pair progrmming must be tha main principle of the work.

We use it for difficult algorithms. The analyst knows what and I how. We both take part in our development.

About Bystander effect: It is irrelevant:

1. IT specialists care about problem and not about responsibility in accidents. (I remember ancient times when everybody can help you, even by trouble-shooting).
2. The both are interested in the problem. They want solve it and they can familiarize with problem and code theyself.
3. etc.

There is sometimes a problem due to vanity, egocetnrism and rivality.

Great! Thanks. I have explored this structure and content of these files yet. But synoptic description of base philosophy is very important.

Great! I must sometimes explore code templates. I have just explored settings and I setted mandatory brackets to if, while, for statement. Bye

We have to choose technologies we will use for our application. Some of requirements: Users work in intranet, GUI is so complex and interactive, fast data typing on the keyboard only, GUI settings and reactions depends on entered data, caching of code lists on workstation in memory or localy, several opened panels of different modules, tasks on background, dynamic menu according to permissions etc. (I can't remember now).

Some reports, statistical queries and outdoor (internet) use cases can be made as a web application. Rich client app can work with web pages too.

I choose NetBeans Platform rich client application - modular, simple distribution, offers all I need. So admit need of java and application installation.

There are many useful projects on Kenai. It would not be closed for public. But current policy is too benevolent. Everybody tries create own project and forgets.

I read carefuly including this advice But I decided to note about NetBeans because readers could mislead.
I am sorry it would not be complete. I am NetBeans fan but under control. Right?
Good article by my opinion.

Why did you ommit NetBeans Platform as rich client?

I noticed you have worked by Eclipse RPC. So you must know other exist, do not you? Sorry for my comment but list two basic RC platforms is so fundamental.

It is better to have many of small modules with strict responsibility. It is less complex problem to make it but a question is what abou understanding of not own module bundle. You can declare dependency on other modules and some modules you do not need refer at all. But dependency structure will get difficult to understand.

I have a such experience with NetBeans modules dependencies. If I choose some dependency to use some module functionality then I need to add many of other modules. E.g. if you would use editor you must add to suite/app a lot of modules you will get wonder - http server module in my case if I remember.

Interesting note: It is more flexible and you can loose dependencies if you expose functionality as a service.
So you can even add several implementations and you can offer them to user to choose.

The other thoughts I have forgoten...

Great and well done! But it became frozen when I switched from C syntax tree to F tree. Beautiful.

Could be able to write preceding comment into IF node in the syntax tree? I made it so in Karel language. Milos

I don't know if this book could me help. I tend to make things more complex
than they need to be. When I review others code I wonder how simple and short
is their code.

I watched J. Tulach's lecture about API design on video and made some notes.
But I have not so much experience and I not so clever as Jaroslav.
Can I earn many by programming at all?

I build new big application over NetBeans Platform and I will use Hibernate to DB connection. I have some difficulties because I must wrap entity library and hibernate jars. It works as a prototype but it has not worked in application yet.

Searching I need use for client or contract retrieval and I want to care about my problem domain only.

There is a few women in IT - for typing or testing.
Women do not program for their own enjoying and for free.

I is better to have domain classes in regular java jar by me. It will be used in many other occasions.

What was worse: I spent some time to look up necessary jars: Couldn't it be difficult to enumerate them?
javax.persistence.jar, org.eclipse.persistence.antrl.jar, org.eclipse.persistence.asm.jar, org.eclipse.persistence.core.jar, org.eclipse.persistence.jpa.jar, org.eclipse.persistence.oracle.jar.
I do not have such a time to try if some of them is not needed.

P.S.: Great tutorial. I looked up it for my job.
