netsong对markoboger说: where can we use uml in xp?(14:59)
markoboger对大家说: and develop tools that support for example XP in modeling(14:59)
markoboger对大家说: And I think , yes you can very well use UML in XP(14:59)
reduce对markoboger说: Are you plan to do that?(14:59)
markoboger对大家说: I guess many of you will have found the site agilemodeling.org(15:00)
markoboger对大家说: There some ideas on how to use UML in XP are described(15:00)
markoboger对大家说: However, the main author there is a consultand. He has to live with the tools available(15:00)
reduce对markoboger说: How many people do you enhanced to develope Poseidon for UML?(15:00)
markoboger对大家说: We are (now) toolbuilders and we can build the tools we feel are necessary to improve a process that involves XP and UML(15:01)

timwap_cn进入聊天室.(15:04)
markoboger对大家说: Well, we are internally using a lot of UML and XP, does that count as Case?(15:05)
markoboger对大家说: However, there are some elements of XP missing(15:05)
freekany对markoboger说: Oh....(15:05)
inevity对大家说: the Argouml Poseidon difference?(15:06)
markoboger对大家说: for example, we found it very hard to introduce testing into an existing project that was not designed for testing(15:06)
incasoftlee进入聊天室.(15:06)
markoboger对大家说: Plus, testing for graphical user interfaces is much more difficult(15:06)
reduce对markoboger说: We think your Poseidon should be next generation in UML? But Rational have thousands people to devolope Rose.Do you think you must convert to RUP?(15:06)
markoboger对大家说: So we had to adjust XP to our needs and curcumstances(15:06)
netsong对markoboger说: so if there r not enough docs, how do u manage ur project?(15:07)
inevity对markoboger说: what is the difference between the Argouml and Poseidon ?(15:07)
founder_chen对markoboger说: TDD maybe better?(15:07)

markoboger对大家说: It was presented at the last XP conference in Italy(15:10)
markoboger对大家说: About profit:(15:11)
michael liu对大家说: refactoring is a good idea, but how to practise testing or show testing phase in uml?(15:11)
markoboger对大家说: Well, we are not makeing profit from the open source project.(15:11)
zjuxxl微笑着对markoboger说: Have you proposed a formal semantics of UML for developing ArgoUML?(15:11)
markoboger对大家说: What we are making profit from is our advances over the open source project.(15:11)
libinjp进入聊天室.(15:11)
timwap_cn对markoboger说: depend on services ?(15:11)
markoboger对大家说: Poseidon is by now much more advanced than Argo.(15:12)

markoboger对大家说: Well, Oncle Bob presented in a talk at the XP conferenc(15:16)
markoboger对大家说: that XP is an instance of RUP(15:16)
markoboger对大家说: General opinion is that RUP is so vague that about any process(15:17)
freekany对markoboger说: Instance?(15:17)
zjuxxl微笑着对markoboger说: what did you do for UML before developing ArgoUML?(15:17)
jedediah离开了聊天室.(15:17)

xlz45进入聊天室.(15:18)
markoboger对大家说: What did I do before Argo:(15:18)
michael liu对markoboger说: how to include a testing process in RUP or express by UML?(15:18)
markoboger对大家说: I was a researcher at hte Hamburg University.(15:19)

wubuy对markoboger说: ?anybody?(15:19)
reduce对markoboger说: Can you give us State chart or Cooperator Chart or Sequence Chart for GEF in ArgoUML?(15:19)
markoboger对大家说: Then I suggested a diagram type that better reflects the structure of methods and how they interact.(15:20)
markoboger对大家说: Sequence diagrams are good for examples but not teh big picture.(15:20)
xqssl进入聊天室.(15:20)
markoboger对大家说: So I developed a method diagram.(15:20)

timwap_cn对markoboger说: how does the process effect the development group ?(15:21)
markoboger对大家说: We ahve a plugin for Poseidon that acutally does generate code(15:21)
timwap_cn对markoboger说: idea or action ?(15:21)
markoboger对大家说: from state charts and alows their execution.(15:21)
markoboger对大家说: You can then see the states change in the diagram(15:21)
markoboger对大家说: a simuliation if you like.(15:21)
freekany对markoboger说: What Plugin?(15:21)
daxiake对大家说: hi markoboger!(15:21)
markoboger对大家说: The plugin is called State2Java.(15:22)
daxiake对大家说: are you like java?(15:22)
freekany对markoboger说: For java?(15:22)
markoboger对大家说: It is in beta right now. We will further advance it.(15:22)
holyking进入聊天室.(15:22)
markoboger对大家说: That also means it it currently free of charge.(15:22)
wubuy对markoboger说: State2Java?(15:22)
markoboger对大家说: But you need the Standard Edition of Poseidon.(15:23)
reduce对markoboger说: Can we see method diagram in Poseidon ?(15:23)
markoboger对大家说: Yes, you can get it from our site at www.gentleware.com(15:23)
wubuy对markoboger说: i never hear about that,please tell me what's State2java?(15:23)
daxiake对大家说: is java and sql2000 good idea?(15:23)
markoboger对大家说: No, we have a prototype of method diagrams but it is not in the product.(15:23)
freekany对markoboger说: AS I know,Code Gerenater of Rose is so Simple,But....(15:24)
markoboger对大家说: State2Java is our plugin to execute state diagrams(15:24)
markoboger对大家说: That really is at the hart of our ideas about extreme modeling(15:24)
markoboger对大家说: Class diagrams dont model behaviour. so you can not execute them.(15:24)
markoboger对大家说: State charts do model behavior. So if you use those you can actually execute models.(15:25)
markoboger对大家说: It is very powerful. But it needs a little rethinking. It is(15:25)
wubuy对markoboger说: o ...thanks(15:25)
markoboger对大家说: a paradigm shift from coding to modeling.(15:26)
ozzzzzz对大家说: do not talk with me(15:26)
markoboger对大家说: But if you take that step, if your models become executable ..(15:26)
zjuxxl进入聊天室.(15:26)
zjuxxl微笑着对markoboger说: How do you think state chart?(15:26)
markoboger对大家说: you can ofcourse also test models.(15:26)
markoboger对大家说: Sequence diagrams are very good for expressing such tests.(15:26)
ozzzzzz对大家说: what is extreme modeling(15:27)
markoboger对大家说: Use cases can be a test map.(15:27)
markoboger对大家说: Extreme modeling is a process suggestion that I develop.(15:27)
markoboger对大家说: There is an article in an XP book about it.(15:27)
markoboger对大家说: I believe there is an article in chinese of it.(15:27)
cinc对大家说: what is the major difference between extreme modeling and other modeling method?(15:28)
markoboger对大家说: There is also a site called www.extrememodeling.org by me(15:28)
markoboger对大家说: It is not quite finished, but it gives you a good idea(15:28)
timwap_cn对markoboger说: does this tools provide model guids ?(15:28)
slam_uml进入聊天室.(15:28)
freekany对markoboger说: oh.So Many Site!(15:29)
markoboger对大家说: The different to other methods? Well, you put more into(15:29)
markoboger对大家说: the model. Actually it is XP not on code but on models.(15:29)
markoboger对大家说: State2java is a plugin for Poseidon. You can find it at www.gentleware.com.(15:30)
ozzzzzz对markoboger说: what is the major difference between extreme modeling and other AM?(15:30)
ozzzzzz对markoboger说: what is the major difference between extreme modeling and AM?(15:30)
markoboger对大家说: Well, agile modeling concentrates on the tools that are available now.(15:30)
markoboger对大家说: And with tools like Rose, it is hard to stay agile.(15:31)
markoboger对大家说: So one of the conclusions of AM is that you better use the white board instead.(15:31)
masc进入聊天室.(15:31)
markoboger对大家说: I have teh advantage that I am developing tools and I can build them the way I need them to make them agile.(15:31)
wubuy进入聊天室.(15:32)
goldenstone进入聊天室.(15:32)
markoboger对大家说: But we are not quite there yet. State2Java is in beta and it need more advancement.(15:32)
markoboger对大家说: For example we started with a refactoring browser for UML(15:32)
cinc对markoboger说: hehe, very intresting...(15:32)
jeersoft进入聊天室.(15:33)
markoboger对大家说: That is also needed for agile modelin with tools.(15:33)
ozzzzzz对markoboger说: ROSE is costliness to me.(15:33)
markoboger对大家说: It is a complex topic and we still need some time to develop all the tools we need(15:33)
cooldot进入聊天室.(15:33)
freekany对markoboger说: I wish Get Successful Case About All Great Ideas of you!(15:33)
cinc对markoboger说: Is CRC Card used in extreme modeling?(15:34)
markoboger对大家说: Yes, rose is very expensive. We are trying to offer tools at a much lesser price.(15:34)
markoboger对大家说: We can do that because we have a different marketing and distribution strategy.(15:34)
reduce进入聊天室.(15:34)
reduce对markoboger说: Are you plan to make Poseidon compitable with Rose that?(15:34)
timwap_cn进入聊天室.(15:35)
timwap_cn对markoboger说: what are you main coustomer ?(15:35)
markoboger对大家说: CRC cards are a good idea. But I guess that would be a step before you go into extreme modeling.(15:35)
markoboger对大家说: Yes, we do plan that. Actually we have an mdl import in our next release(15:35)
markoboger对大家说: You will then be able to read in Rose files into Poseidon.(15:36)
markoboger对大家说: Our largest customer is HP at this point in time.(15:36)

wubuy对markoboger说: can u give any info about xp or testing(15:40)
wubuy对markoboger说: website?(15:40)
wubuy对markoboger说: or books(15:40)
markoboger对大家说: Oh, you need a team. We found it very difficult to do XP with a small team. it is propably best with 6 to 8 people(15:40)
coolie2k对wubuy说: don't you know testing, sigh(15:41)
wubuy对markoboger说: we are three man(15:41)

awarmer对大家说: Which tools do you use in developing poseidon?(15:41)
markoboger对大家说: If you have too few, then you can not pairprogram since often you cant find the partner you need.(15:41)
wubuy对markoboger说: is we equal useing XP(15:42)
markoboger对大家说: Go ahead and try. It works better with a mid size team. But if you have a small team, XP is still better than anything else.(15:42)
markoboger对大家说: Tools:(15:43)
coolie2k对markoboger说: Can requirement documenting use pairprogram?(15:43)
wubuy对markoboger说: HOW start?(15:43)
markoboger对大家说: For modeling, we use our own tool, of course.(15:43)
markoboger对大家说: For programing we use IDEA. We also use Netbeans an eclipse.(15:43)
wubuy对markoboger说: i am wondering...(15:43)
caozq进入聊天室.(15:44)
markoboger对大家说: Also some emacs, but most develpers here now use IDEA. it is a great product.(15:44)
cinc对markoboger说: is IDEA suitable for web development?(15:44)
firebird_online微笑着对markoboger说: what do you think about pairprogram?I mean the developer's diathesis(15:44)
cinc对markoboger说: such as jsp site.(15:44)
markoboger对大家说: We do a lot of pair modeling. So I guess you could do pair requirements modeling ;-)(15:44)
markoboger对大家说: How to start on XP? Well, difficult question(15:45)
wubuy对markoboger说: expert(15:45)
markoboger对大家说: But the corner stone is testing. Get familiar with junit(15:46)
wubuy对markoboger说: i think u must can do it,why difficult?(15:46)
markoboger对大家说: and first write some tests. This will make your API much simpler and(15:46)
markoboger对大家说: it also makes it testable. That is very important.(15:46)

wubuy对markoboger说: en ...thanks(15:47)
markoboger对大家说: Testing has to be done by the people doing the programing.(15:47)
markoboger对大家说: You might still want a test process and test engineers.(15:47)
markoboger对大家说: but you need to write tests by the develpers.(15:48)

wubuy对markoboger说: other question:is any project befitting used with XP?(15:48)
markoboger对大家说: You use tests in a different way. You don't try to find bugs.(15:48)
firebird_online微笑着对markoboger说: doesn't xp need SE?(15:48)
markoboger对大家说: you try to prove that your feature works under all situations.(15:49)
cinc对大家说: in XP you should write test first and then write code to let test pass, it is an important XP principle.(15:49)
coolie2k对markoboger说: does that mean feature test?(15:49)
reduce对markoboger说: How pairprogram work? Two people work at same thing in the meantime?(15:49)
markoboger对大家说: And if you keep your tests updated you can change something and see if this broke something else.(15:49)
markoboger对大家说: This gives you much more currage to change something.(15:49)
markoboger对大家说: And so you become more agile.(15:50)
cinc对大家说: How do you deal with automatic testing? using jarkata ant?(15:50)

markoboger对大家说: Both look at the code. One focuses more on details one more on the global picture.(15:51)
markoboger对大家说: But this can change all the time.(15:51)
firebird_online微笑着对markoboger说: agile?how xp prove the quality(15:51)
coolie2k对markoboger说: So agile program must need XP(15:51)
wubuy对markoboger说: hehe,i hear Pair programming,but that seem like no efficiency(15:51)
markoboger对大家说: Yes, we do a lot of pair programming for Poseidon.(15:51)
markoboger对大家说: It ensures that all know about the architecute, it reduces design problems.(15:52)
coolie2k对markoboger说: since developer can not write test case while coding.(15:52)
firebird_online微笑着对markoboger说: do the two developer often change role?(15:52)
markoboger对大家说: it increases fun. It is more productive.(15:52)

aiwangji进入聊天室.(15:53)
markoboger对大家说: After all, most time is spent on fixing code. So if you can reduce that by pair programming you win.(15:53)

nongren进入聊天室.(16:00)
markoboger对大家说: We were actually sitting in a train and he used his laptop.(16:00)
markoboger对大家说: So, we decided we wanted a little program that converts currencies.(16:00)
markoboger对大家说: So, you start with a little test that describes what you actually want to do and what the result should be.(16:01)
markoboger对大家说: For a currency converter, you migh want to convert 100 Dollar to Euro.(16:01)
markoboger对大家说: Well, currently that is very simple since the exchange rate is about 1.(16:02)
markoboger对大家说: So the result should be, say 98.(16:02)
markoboger对大家说: You write that in a test using Junit.(16:02)
markoboger对大家说: You write the interfaces so that your test compiles.(16:03)
markoboger对大家说: Now your test fails (there is no implementation yet)(16:03)
markoboger对大家说: But the interface already is testable, because you designed the test first.(16:03)
markoboger对大家说: It might seem trivial for such an example, but it gets important for large projects.(16:04)
wubuy对markoboger说: best regard.thanks u(16:04)
markoboger对大家说: So your test fails. Well, now we can implement the method.(16:04)

linmeimei进入聊天室.(16:05)
markoboger对大家说: Oh, and remember, our tests are all automated. They all result in true or false.(16:05)
markoboger对大家说: So we now have one little feature implemented. Conversion of 100 Dollar to 98 Euro.(16:06)
markoboger对大家说: Now lets test, if this works also for negative numbers. -100 Dollar should result in -98 Euro.(16:06)
wubuy进入聊天室.(16:06)
markoboger对大家说: Write a test and see if it does.(16:06)
markoboger对大家说: Then go on. Lets say now we want to decide which currecy you want to use.(16:07)
markoboger对大家说: So you first write a test doing that.(16:07)
markoboger对大家说: Get it to compile, so you know you have the right interface. It fails, since it is not imple(16:08)
markoboger对大家说: Oh and here pair programing is important. Discuss what interface is best. Get different ideas. The interface is really important.(16:09)
markoboger对大家说: Now, implementing this might (or might not) break your fist test. But since you have a test for it, dont worry.(16:09)
cunny进入聊天室.(16:09)
markoboger对大家说: If you did something to break the code, the test will fail and you will immediatly know what the problem is.(16:10)
markoboger对大家说: This is the point were you gain speed over other methods. Your debuging is much faster, since you already have tests for every little feature.(16:11)
markoboger对大家说: You know exactly what went wrong and were to look for the problem.(16:11)
markoboger对大家说: Now, we use a lot of UML modeling infront or while doing this.(16:11)
markoboger对大家说: We tend to think and work in structures a lot and UML gives you a better picture(16:12)
markoboger对大家说: of the structure. We use our own roundtrip tool to do that.(16:12)
markoboger对大家说: You get the picture?(16:13)
wubuy对大家说: no,(16:13)
markoboger对大家说: Kent Becks book about XP explains all this very well. It is a very good book.(16:13)

markoboger对大家说: Now, with software the architecute is harder to see.(16:16)
markoboger对大家说: but here are similar things, architectures that recure.(16:17)
cavinniuk微笑着对markoboger说: could you explain, i can't understand your meaning?(16:18)
markoboger对大家说: Like, we have a tree layer architecture in Poseidon, a repository, controller and interface. The interface itself is also built up in three layers. Then we use an event(16:18)
markoboger对大家说: mechanism to communicate changes.(16:18)
markoboger对大家说: If your code is clean, you can find such architectures in your UML diagrams.(16:19)

markoboger对大家说: They have described a set of patterns that recure in software and gave them a name.(16:21)
firebird_online微笑着对markoboger说: what's mean 'our tests are all automated'?just with junit?(16:21)
markoboger对大家说: They also described them. Gamma, by the way also wrote Junit, together with Kent Beck.(16:22)

wubuy对markoboger说: now,in china,some project(not a little)is only have 2 or 3 peple.how can them use XP?if they according to your just said,i think the peple number is to few.(16:22)
wubuy对markoboger说: can you give me a best advise?(16:22)
markoboger对大家说: Yes, tests are all automated. We use JUnit for code testing and something called QFtest for the user interface.(16:22)
wubuy进入聊天室.(16:23)
markoboger对大家说: Gef is opensource.(16:23)

markoboger对大家说: But how do you know, when you start? We had to change the architecture of Argo a couple of times to build Poseidon.(16:26)
markoboger对大家说: But that is a lot of work.(16:26)
markoboger对大家说: What devepers to pair? Well, the ones on your team, all of them.(16:27)

timwap_cn对markoboger说: what is XP' base ? team of project , or a project .(16:40)
