The term Continuous integration originated with the extreme programming development process.It is a practice that is particularly useful for medium to large scale development projects. The essence of it lies in the simple practice of everyone on the team integrating frequently, usually daily, against a controlled source code repository. I have been in software development for quite some time and based on experience, i have learned a common story of software projects: integration is a long and unpredictable process. What people find out as they try CI is that it's much easier than it sounds, and that it makes a huge difference to development. Although Continuous Integration is a practice that requires no particular tooling to deploy,it is useful to use a Continuous Integration server. The best known such server is CruiseControl, an open source tool originally built by several people at ThoughtWorks and now maintained by a wide community. Since then several other CI servers have appeared, both open source and commercial - including Cruise from ThoughtWorks Studios.

@kobojunkie do u have a rough idea of the project scope? by this i mean the establishment of a system boundary/context.

Harzard has been quite average in the EPL so far in my opinion.

1025: is not enough to charge him. what about the refs and all other agents of the fa whose interests are always to see the fall of chelsea. why will saurez finish the match and even score after the 6 minutes given by the useless match officials who were all blind to the action of saurez?
it is a shame that man u fraudulently in conjunction with fa won the league. epl is a joke.

If charging suarez is not enough for u what then would be enough? or would u rather prefer if he is lined up against the wall and shot. Will that be enough for u?

1025: if i have the fa and a lot of the refs in my pocket like fergie, i will surely do better than him.

Dude stop hating and give credit where its due.Wheater u like it or not the man is a legend deal with it.

chelseabmw: ARSENAL SHOULD EITHER LOOSE OR DRAW THIS GAME.....I SEE THEM LOOSING THIS GAME

AND I SEE CHELSHIT LOOSING TO LIVERPOOL.

I guess u meant to say integrate rather than embed. Anyway it is possible to mix both java and c/c++ code in a single application using a language independent component model such as CORBA or COM+

In object-oriented programming, the concept of an active object refers to objects that exist in their own thread of execution and have their own address space.Calls to active objects are inheretly asychronous(i.e non-blocking) hence active objects are a better way to implement multi-threading than using raw threads. This is because active objects tend to multi-task co-operatively within a thread also using active objects does not require sychronization as opposed to using raw threads where data shared by threads must be protected with access synchronization primitives such as mutexes or semaphores.

In my opinion for an application to achieve great user experience(UX)/high usability levels, it is not enough to just be good in html, css, silverlight, WPF or whatever ui technology u wish employ. While these are obviously important, i believe its more important to take a user-centred approach to ui design. It is important as a ui designer that u involve potential users of an application in your ui design process through prototyping and regular feedbacks to enable u to properly fine tune your ui to match the expectations of your target users/user groups.

[quote author=dansmog++]so? What do you suggest? What you post is not a question neither is it a way out!! ** NO OFFENCE**[/quote]The post is not meant to be a question it is just an observation. If u want to suggest something pls feel free.

Hi guys, as a developer i am not a very good ui designer but i beleive that the ui is one of the most important aspects of an application becos to users of your application the interface is the system it is what they see and interact with. Many good programmers i know are not very ui designers hence the ui is not given the attention it deserves. Many applications suffer from poor usability not because of lack of features/functionality but of poor ui design.

so UI/UX Developers, can we see some screenshots of your best works for either a desktop, mobile or web application.

In my opinion programming is a craft that can be learned and mastered like any other vocation. For me a programmer is a software craftsman.

One good thing about quickly is that it can be extended to add templates for just about any kind of application. Which means that with enough programming knowledge u can create a template for a qt application for example using the language of your choice.

lordZOUGA: quickly is cool... qt framework is better..

I have heard good things about qt framework but i haven't tried it though as am more into gtk.

Quickly is a great little tool for producing and packaging Ubuntu (PyGTK) GUI applications.Quickly integrates project creation, code editing, GUI editing, running and debugging, as well as packaging and sharing via Launchpad.net, all in one easy to use command line interface. Quickly generates your project ready to run with everything you need for a complete Ubuntu Application. Quickly is as simple as installing from the Ubuntu Software Center or firing up a terminal and running:

sudo apt-get install quickly

Both are important but i think skill is more important. You need skill to validate your certification

chelseabmw: [b]See this tadpole saying am arrogant....If u are an arsenal fan then ur brain needs a technical adjustment because your team for the past 8 years has nothing to show for...A useless team that common Birmingham dealt with in the final? or is it same useless team thats cant qualify for semi's in the UCL? Or is it same dead team that sell their best players to their rivals? or is it same foolish club that don't want to take the first or second position but are always happy,comfortable and satisfied with the fourth position?

We finished 6th last season but won the UCL cup,how about that? If u are told in ur wildest dream that arsenal is going to finish ahead of chelsea this season wouldnt u wake up and slap the person.....eh eh/// am not boasting,you know why? because i got MAZACAR,moses,lampard,ramires and lots more.... I never called any club names but the fans...Arsenal and arsenal fans are two different things..... if you want me to define an arsenal fan for you,i will gladly do that..........KTBFFH[/b]

The whole world is already aware the u won the UCL but this thread is about the EPL and i belevie they are two completely different competitions if u want to talk about how u won the UCL last season then start a new topic on that besides did u not have MAZACAR,moses,lampard,ramires and lots more when u where dumped out of the UCL at the group stage.

chelseabmw: I DON'T NEED TO THINK BECAUSE WE ARE ALREADY THERE WE ARE NOT ARSENAL FANS THAT ALWAYS THINK

dude don't be so arrogant, u might just end up finishing 6th like last season becos football is very unpredictable. So pls stop boasting and show respect to all the other teams in the EPL.

Hi i know its a bit of an over kill considering the fact that your project is a simple CRUD app but i would also consider writing some unit tests especially for your domain and DAO objects.

webdezzi: APIs has come to stay and i still wonder why SOAP still exist where JSON makes live easier

I think soap still has its nitch. In general i would prefer soap if I need to pass around a lot of text since XML excels at wrapping and making up text. But when passing around small data objects, i would tend to use json as it is smaller, easier to parse and more readable

Hi guys, just want to talk about how valuable apis have become in modern programming. APIs are everywhere in one form or another from programming language libraries to hosted services. I personally think that programming will be very difficult without apis. Its the best thing since sliced bread in my opinion. Can u imagine what programming would be like without apis.

1025: i am not the one making u sick rather ur greed and love for money. tell me, why won't this man get heart attack? if somebody kill himself, na me u wan come blame here abi? abeg shut up. if you and ur club refuse to change ur attitudes toward money and big players, very soon, fans attack, players attack, head attack and other forms of attack with join heart attack. do u know how many fans this ur club policies have killed? do u know how many poor fans u have given this heart attack without reporting them here on nairaland? ok, why I

chelsea, man u, man city, tottenham etc chairmen not having heart attack?
come, are u aware that arsenal fans want that man dead today and tomorrow? wait until swansea city discharge una from fa cup na him u go know how far.

Abeg shut up your smelling mouth. What has fa cup game got to do with this. Your chelshit that is not greedy were disgraced by newly promoted west ham and have also being dumped out of the cl. You should be more worried about that. Mumu

1025: uncle, did u just escape from a mental rehab? which life? did ur wenger think about life when he sell all good players and leave ramsey and co to win things for u ppl? are u saying we are responsible for the chairman's heart attack? the worst part of it now is that the fa even fixed arsenal and swansea in fa cup? if to say na u be that chairman, u no gp get heart attack?
my advise to u is that u join another team before u join ur club's chairman in the heart attack galore.
u ppl are always talking about profit so now that heart attack don join, make we see.

What is wrong with u? Talking nonsense again as usual someone is fighting for his life instead wishing him well u are vomiting rubbish. Even if u hate arsenal that is no excuse to make this kind of comments. You really make me sick. There is more to life than football man.

webdezzi: In this case, we could see actions with links provided and less confusing sentences.

Whatever, weather u can see actions with links and less confusing sentences or not is a completely different issue my point is that he could have used fewer sentences to say what he said. So in my opinion he has not expressed himself properly for someone who claims to be an english language guru.

lordZOUGA: As a PC user, you are probably guilty of collecting files from people and keeping it haphazardly in any folder on your PC and then later lose track of where you kept the files or you are the type that would really like a neatly arranged PC with the mp3s going to the music folder and the movies going to the video folder or the compressed files going to a predefined archive folder but you are too lazy to enforce such a rule(people like me).
If you fall into any of the category above, you must try this software. It allows you to add the notorious folders where you normally drop the files "haphazardly" and to also add folders where you would prefer certain files to be like Music folder for mp3, m4a, ogg or any music format you use. Once you specify the notorious folder and you add a file that is not meant to be there, it automatically whisks it away to the right folder immediately..

I think u could have said this with fewer sentences.

lordZOUGA: its just that what he said, he could have said with fewer sentences....
Besides, if he wasn't ranting and was interested in proving that processes are better than threads, he should have written a test in his favourite programming language or outline a test illustrating what he said above then benchmark the test and provided the result. Thats how science works. I believe there are more developers here than journalists..

I am not trying to prove that processes are better threads I am only expressing an opinion based on personal experience u don't have to agree with it as its only an opinion. Besides if u think that I could have used fewer sentences well that's also a matter of opinion and I make no apologies for that.

lordZOUGA: lol. I have always wondered why that guy can't express himself

And I guess u can express yourself right? Mr english guru

WhiZTiM: It depends on what system you are building. You made a reasonable point... But I really do not approve your excuses for your adoption of Interprocess Communication(IPC).
You know quite well that context switching can be expensive. Those crash safety issues you raised arent good excuses. Remember Defensive programming and persistent objects?? For scalability reasons, If you have multiprocessing in mind, you would definitely have to localize most of your routines, still needing threads to do that... Running a remote process wouldnt speed up your app without having most routines atomic and local. I know this cause... Theres a project am working on, dynamically processing a file between two entirely different opensource software, in GTK and WxWidgets....

I totally agree with u as regards the kind of system been built but it is important to understand that i was talking about system-level concurrency as opposed to component-level concurrency. If your system is structured internally as a collection of loosely coupled components for example, i find to more useful to impose process-based concurrency at the system-level by mapping each component to its own process and leave the multi-threading decisions to the individual component developers. But if for example your system has a monolithic internal structure where all the system elements inherently share the same process, then u really have no choice but to employ thread-based concurrency at the system-level.

cjotech: you are making this look like a big deal.
wen u look at the Architecture of a particular ucontroller, its from their that u can determine if the ucontroller in question can perform the particular task u want. then from the instruction, u use to program the micro controller @assembly language level.

I totally understand your point but what i am talking about is the ease at which a program compiled for one ucontroller platform can be moved to a different ucontroller platform(without modification)from a different manufacturer with similar capabilities/instruction set.

Sometime ago i was working on a development project with a small team of developers and was tasked with the responsibility of coming up with a concurrency architecture for the entire solution. At first i was not sure weather to base my concurrency model on threads or on processes and after much tinkering for about a day or so i finally decided to go with processes. Some of the other developers on the team wondered why i decided to go with processes their argument was that process creation and communication was resource intensive and slow compared to threads which is true but i still tend to favor a process-based concurrency model over a thread-based model for the following reasons:

1. Fault-tolerance and scalability is the main advantages of using processes vs. threads.

2. A system that relies on shared memory or some other kind of technology only available when using threads, will be useless you want to run the system on multiple machines. Sooner or later you need to communicate between different processes.

3. Another advantage of processes is that they can crash and you are perfectly ok with that, because you just restart them (even across network hosts). If thread crashes, it may crash the entire process, which may bring down your entire application.

4.Thread-based concurrency models tend to be buggy and difficult to implement correctly.

Hi guys i first came across the the term software archaeology while listening to a podcast by dave thomas of the pragmatic programmers on software engineering radio. it basically involves the digging, reading and research of legacy code that was either written by you or some other programmer of which the aim is to discover and extract useful code artifacts (i.e algorithms) that can be used in new and future applications. Software archaeology can be tedious and time consuming as well especially if u are working with a large code base but it can also pay huge dividends if done properly. It allows u to as a programmer to develop your personal algorithms library which is a very useful asset to have because no matter how good a programmer u are u will always be faced with complex software requirements of which u might not have a clue how to go about implementing.

cjotech: Yep bro; d program can be modified for any other ucontroller, provided u can play around wit its instruction set and architecture!

I don't think its possible to play around with the instruction set as this already fixed and cannot really be altered/modified. I believe the best approach that can be taken to achieve portability on other micro-controller platforms is to program against a Real-time operating system (RTOS).
