  • Documenting software architectures that serve multiple markets

    - by wsb3383
    Hello, I'm the lead developer/architect wanna-be on a J2EE based system/platform at work that serves both real estate and automotive markets. The systems consists of a set of database back ends, web services and two web clients. The platform ends up serving 3 different products: an internal vehicle inventory system for use by company analysts, an external dealer management system (commercialized product), and a real estate inventory system (commercialized). In other words, it follows a software product lines approach....My question is, I'm having trouble communicating to other technical and some business people how this platform architecture is one system that serves multiple markets (by leveraging some existing assets combined with minor modifications)....Is there a formal modeling language that can simplify communicating this intent? I should note that I haven't read much about software product lines, so I'm not sure if there is actually a standard modeling approach to SPL that i'm not aware of....I'm also interested in knowing if there are special configuration management practices for such systems. thanks,

  • Cant install software

  • Oracle WebCenter: uma nova vis&atilde;o para os Portais

    - by Denisd
    O conceito de “Portal” existe há muito tempo, mas está sempre mudando. Afinal de contas, o que é um portal? Nos primórdios da internet, o termo “portal” era utilizado para sites que guardavam muitas páginas (ou seja, muita informação). “Portal de notícias” era um termo comum, embora estes “portais” não passassem de um conjunto de páginas estáticas, que basicamente serviam conteúdo aos usuários. Com a evolução da tecnologia, os web sites passaram a ficar mais dinâmicos, permitindo uma interação maior do usuário. Sites de comunidades sociais são o melhor exemplo disso. Neste momento, o “portal” passou a ser não apenas um grupo de páginas, mas um conjunto de serviços e recursos dinâmicos, como a possibilidade de publicar fotos e vídeos, e compartilhar este conteúdo com amigos on-line. Aqui temos o que podemos chamar de “Portais Sociais”. Ao mesmo tempo, dentro das empresas, outra mudança estava acontecendo: a criação de padrões de comunicação entre aplicativos, sendo o mais famoso destes padrões a tecnologia de Web Services. Com estes padrões, as aplicações podem trocar informações e facilitar a experiência dos usuários. Desta forma, é possível desenvolver mini-aplicativos (chamados “portlets”), que publicam informações dos sistemas corporativos nas páginas dos portais internos. Estes portlets permitem interações com os sistemas, para permitir que os usuários tenham acesso rápido e fácil às informações. Podemos chamar estes portais de “Portais Transacionais”. Aqui temos 2 pontos que eu gostaria de chamar a atenção: 1 – O desenvolvimento de portlets é necessário porque eu não consigo publicar uma aplicação inteira no portal, normalmente por uma questão de padrões de desenvolvimento. Explicando de uma forma simples, a aplicação não foi feita para rodar dentro de um portal. Portanto, é necessário desenvolvimento adicional para criar mini-aplicativos que replicam (ou melhor, duplicam) a lógica do aplicativo principal, dentro do portal. 2 – Os aplicativos corporativos normalmente não incluem os recursos colaborativos de um portal (por exemplo, fóruns de discussão, lista de contatos com sensores de presença on-line, wikis, tags, etc), simplesmente porque este tipo de recurso normalmente não está disponível de forma “empacotada” para ser utilizada em um aplicativo. Desta forma, se eu quiser que a minha aplicação tenha um fórum de discussão para que os meus clientes conversem com a minha equipe técnica, eu tenho que desenvolver todo o motor do fórum de discussão dentro do meu aplicativo, o que se torna inviável, devido ao custo, tempo e ao fato de que este tipo de recurso normalmente não está no escopo da minha aplicação. O que acaba acontecendo é que os usuários fazem a parte “transacional” dentro do aplicativo, mas acabam utilizando outras interfaces para atender suas demandas de colaboração (neste caso, utilizariam um fórum fora da aplicação para discutir problemas referentes ao aplicativo). O Oracle WebCenter 11g vem para resolver estes dois pontos citados acima. O WebCenter não é simplesmente um novo portal, com alguns recursos interessantes; ele é uma nova forma de se pensar em Portais Corporativos (portais que reúnem os cenários citados acima: conteúdo, social e transacional). O WebCenter 11g é extenso demais para ser descrito em um único post, e nem é a minha intenção entrar no detalhe deste produto agora. Mas podemos definir o WebCenter 11g como sendo 3 “coisas”: - Um framework de desenvolvimento, aonde os recursos que as minhas aplicações irão utilizar (por exemplo, validação de crédito, consulta à estoque, registro de um pedido, etc), são desenvolvidos de forma a serem reutilizados por qualquer outra aplicação ou portlet que seja executado neste framework. Este tipo de componente reutilizável é chamado de “Task Flow”. - Um conjunto de serviços voltados à colaboração, como fóruns, wikis, blogs, tags, links, people connections, busca, bibliotecas de documentos, etc. Todos estes recursos colaborativos também estão disponíveis como Task Flows, desta forma, qualquer aplicação que eu desenvolva pode se beneficiar destes recursos. - Um “Portal”, do ponto de vista tradicional, aonde os usuários podem criar páginas, inserir e compartilhar conteúdo com outros usuários. Este Portal consegue utilizar os recursos desenvolvidos no Framework, garantindo o reuso. A imagem abaixo traz uma visão deste Portal. Clique para ver em tamanho maior. A grande inovação que o WebCenter traz é que a divisão entre “portal” e “aplicação” desaparece: qualquer aplicação agora pode ser desenvolvida com recursos de portal. O meu sistema de CRM, por exemplo, pode ter um fórum de discussão para os clientes. O meu sistema de suporte pode utilizar Wikis para montar FAQs de forma rápida. O sistema financeiro pode incluir uma biblioteca de documentos para que o usuário possa consultar os manuais de procedimento. Portanto, não importa se eu estou desenvolvendo uma “aplicação” ou um “portal”; o que importa é que os meus usuários agora terão em uma única interface as funcionalidades dos aplicativos e os recursos de colaboração. Este conceito, dentro da Oracle, é chamado de “Composite Applications”, e é a base para a próxima geração dos aplicativos Oracle. Nos próximos posts iremos falar (é claro) sobre como o WebCenter e o UCM se relacionam, e que tipo de recursos podem ser aproveitados nas aplicações/portais. Até breve!

  • Software management for 2 programmers

    - by kajo
    Hi all, me and my very good friend do a small bussiness. We have company and we develop web apps using Scala. We have started 3 months ago and we have a lot of work now. We cannot afford to employ another programmer because we can't pay him now. Until now we try to manage entire developing process very simply. We use excel sheets for simple bug tracking and we work on client requests on the fly. We have no plan for next week or something similar. But now I find it very inefficient and useless. I am trying to find some rules or some methodology for small team or for only two guys. For example Scrum is, imo, unadapted for us. There are a lot of roles (ScrumMaster, Product Owner, Team...) and it seems overkill. Can you something advise me? Have you any experiences with software management in small teams? Is any methodology of current agile development fitten for pair of programmers? Is there any software management for simple bug tracking, maybe wiki or time management for two coders? thanks a lot for sharing.

  • Recurring lsb-release and Software Center glitch after installing MATE

    - by infomorph
    I just recently upgraded to Ubuntu 11.10. Not a fan of Unity, so I decided to try out the MATE desktop from Linux Mint. I added the Mint repository, grabbed and installed the MATE packages, and got rid of the repo so I wouldn't be downloading any other Mint packages. I did have some glitches with the packages (missing dependency stuff), but I fixed it. As other users have reported, installing MATE temporarily breaks the Ubuntu Software Center because lsb_release shows the machine as Linux Mint rather than Ubuntu. I can fix it as noted in this answer by editing /etc/*release and /etc/*issue. Problem is, this only works until I reboot the machine. Every time I reboot, /etc/lsb-release and /etc/issue revert to Linux Mint, breaking Software Center again until I edit them, again. Can anyone help me pin down what keeps changing these files? Much appreciated, thanks. Rephrasing the crux of the problem: where do /etc/lsb-release and /etc/issue get their info from? What would cause them to be revised on reboot?

  • Why can't I install from software center?

    - by user64720
    There was a problem upgrading to Firefox 13. This error kept returning: /var/cache/apt/archives/firefox_13.0+build1-0ubuntu0.12.04.1_i386.deb W: Waited for dpkg --assert-multi-arch but was not there - dpkgGo (10: There are no "child" processes). Now it seems that there is some problem with dpkg and I can't install anything from software center. I already tried to clean previous packages with sudo rm /var/lib/apt/lists/* -vf and then sudo apt-get update, it didn't work. When running sudo dpkg --configure -a, I get this: dpkg: problems with dependencies prevent the configuration of firefox-globalmenu: firefox-globalmenu depends on firefox (= 13.0+build1-0ubuntu0.12.04.1); however: The package is not installed. dpkg: error while processing firefox-globalmenu (--configure): problems com dependencies - leaving unconfigured There has been found errors while processing: firefox-globalmenu What should I do to fix this?? EDIT: I don't have the necessary expertise to understand why what I did worked and what was causing the conflict, but anyway, since there was a problem with firefox-globalmenu:, I went to synaptics package manager, I removed this particular package and reinstalled it. After that, I was able to install Firefox from synaptics and also any other applications from software center. However, still there was a problem, when running sudo apt-get update, the following kept returning: Failed to get gzip:/var/lib/apt/lists/partial/archive.ubuntu.com_ubuntu_dists_precise_main_binary-i386_Packages Verification code hash doesn't match. E: Some archives index failed at being downloaded. They have been ignored, or older copies are used instead. So I typed sudo rm /var/lib/apt/lists/* -vf in terminal and then again sudo apt-get update and everything is fine now. I did this before an answer was posted, anyway I agree the problem was that particular package and its removal. So I'll mark the below answer as accepted.

  • How long to wait before Humble Bundle games appear in Software Centre?

    - by Synesso
    At software-center.ubuntu.com it says Thank you for downloading your Humble Bundle games from the Ubuntu Software Center Notes: As these games have been recently added to Ubuntu Software Center it might take a minute for them to appear. If you see a "Not found" message, Ubuntu Software Center is working in the background to update the list of available apps. When I click on a link, the software centre opens and it says There isn’t a software package called “swordandsworcery” in your current software sources. I have waited for about 30 minutes now. I have also executed sudo apt-get update & restarted software centre to no avail. Do I keep waiting?

  • Can I use other ways than Ubuntu Software Center to open `apt` links?

    - by cipricus
    Without Ubuntu Software Center in Lubuntu I was unable to edit opening apt links in any program in Firefox (see this question) After installing Ubuntu Software Center, that problem is solved, but could I use other program instead of Ubuntu Software Center for the same purpose? I find it too heavy, and to install I prefer the Terminal, gdebi, Lubuntu Software Center or the Synaptic. (Now that I have the apt option in Firefox/Preferences/Applications, I try to change Ubuntu Software Center to Lubuntu Software Center but this does not change the option.)

  • Lessons on Software Development – From Bruce Lee!

    While we as software developers are used to learning lessons and adopting techniques from other disciplines, it is not often that we look to the martial arts for new ideas on development approaches.  However, this blog post does just that. The author end with the following thought: In the end, follow Bruce Lee’s advice: Examine what others have to offer, take what is useful, and adapt it if necessary.

  • What is better Ubuntu Tweak or Software center?

    - by S B
    Ubuntu Tweak has served me very well over the past few release cycles, but there seems to be more and more of an overlap between Ubuntu Tweak and the Ubuntu Software Center. I wanted to know whether these two great apps are headed for a head-to-head crash (which would be a shame for the Ubuntu community) or is there some way for the two projects to complement each other, integrate and make my favorite distribution even better? Happy new year to everyone.

The system will have to: handle the money part (PayPal&Co. are OK) let user buy old issues of the Magazine warn user on subscription expiring, etc. PDF stamping and WordPress integration (user credential sharing, page access of subriscrebed goods, etc) will be a big plus.

    Freedom: http://macfreedom.com/ Anti-Social: http://anti-social.cc/ Simply put: Where can I find a alternative software to either-or/both these apps? Note: Part of the appeal of these apps is allowing the user to explicitly make it extra difficult to re-enable these services. Unplugging the network cable might seem to achieve the same results from an glance, but the added difficulty in re-enabling those services is what makes these apps valuable.

  • Software engineering project idea feedback [on hold]

    - by Chris Sewell
    I'm a third year student currently undergoing my project/dissertation section of my degree. I have drafted a proposal for my final year project and would appreciate any feedback. The feedback can be anything constructive either specific to this proposal, the area that I will be working and researching in or my ideas. I will accept all input. Aims My aim is to attempt a proof of concept and prototype a runtime-as-a-service (RaaS). This cloud based runtime will allow clients to dynamically offload tasks or create cloud applications. Currently software-as-a-service (SaaS) cloud applications are purpose built and have a predefined scope in which they can assist or serve the client; this scope cannot be changed without physical alteration to the client and server software. With RaaS the client potentially could define any task it wanted at any time depending on its environment variables, the client and server would then communicate parameters and returns for that task. For the client to utilize a RaaS it must be able to conceive and then define a task using an appropriate XML vocabulary. As the scope of the cloud solution is defined by the client at its runtime, the cloud solution only has to exist for as long as the client requires it to as opposed to a client using a dedicated service. Deliverables The crux of the project will require an XML vocabulary in which the client and server will communicate. I’ll prototype the server application that will dynamically create and manage cloud solutions. The solution will be coded using an interpreted language, such as python or javascript, which can evaluate expressions in runtime or a language that can dynamically compile such as C# or Java. As a further proof of concept I will also produce a mock client that offloads tasks to the server. The report will attempt to explain the different flavours of cloud computing solutions including infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS) and SaaS including real world examples and where the use of a RaaS could have improved the overall example solution. Disclaimer: I'm not requesting stakeholders in my project nor am I delegating work. Any materials other than feedback, advice or directions will not be utilized.

  • What snapshot software do you recommend? [closed]

    - by Charbel
    Possible Duplicate: What screenshot tools are available? Hi, is there a snapshot software for Ubuntu? Something like SnagIt? The idea is many times I have to take the snapshot and edit the image to crop to my region of interest, SnagIt does that automatically and very nicely. Another feature is to take a snapshot of text (that can't be otherwise copied - like text in a photo) and then parse it into actual text document using an OCR technology. Thanks
