  • WCSF vs MEF, What's Best For Me?

    - by Galilyou
    Hey fellows, I'm working on a large web application that includes many modules (CRM, Inventory, Administration, etc.) What I want to accomplish is to be able develop each of these modules independently (the UI, Core Logic, DataAccess Logic, and all) and then integrate them all together into a core module (this integration should only be a change in the configuration file). For example, if I have a core module named Host, I should be able to add the CRM module to the host module by simply adding this line to the host's configuration file: <module name="CRM" /> I did some reading on the WCSF, and found that it can help integrate some modules together, but it really doesn't offer so much help in terms of integrating those UI elements. Some friends suggested MEF for the job, but I haven't looked at that yet. What do you guys think? Is it possible to achieve this level of modularity, and how much work do I have to put into it to get it working?

  • Parse string with bash and extract number

    - by cleg
    Hello I've got supervisor's status output, looking like this. frontend RUNNING pid 16652, uptime 2:11:17 nginx RUNNING pid 16651, uptime 2:11:17 redis RUNNING pid 16607, uptime 2:11:32 I need to extract nginx's PID. I've done it via grep -P command, but on remote machine grep is build without perl regular expression support. Looks like sed or awk is exactly what I need, but I don't familiar with them. Please help me to find a way how to do it, thanks in advance.

  • JBoss ignores @RemoteBinding annotation

    - by tputkonen
    I would like to specify JNDI name for an EJB3 bean using annotation, but JBoss 5.1.0 GA seems to ignore the annotation completely. Bean's annotations are: @Remote(Foobar.class) @Stateless(name = "Foobar") @TransactionManagement(TransactionManagementType.BEAN) @RemoteBinding(jndiBinding="ejb/Foobar") public class FoobarBean implements Foobar { ... I tested deploying also using @RemoteBindings annotation, but the result was same: @RemoteBindings({@RemoteBinding(jndiBinding="ejb/Foobar")}) The bean does not get bound to JNDI with the specified name, and the log file doesn't give any clues.

  • Higher than high-level web frameworks or CMS's?

    - by Ben
    I'm looking for options that allow very high-level web site development with these special characteristics: not requiring the user to program in a complex programming language not requiring the user to use GUI-like administration areas allow the user to "program" in a lightweight markup language The last point is not only about look and structure of the output but also about creating simple dynamic output. For example: listing pages fetching the content of other pages doing a site search and displaying its output dynamically show or hide parts of the page depending on login status Of course, I am not expecting a solution that provides the same possibilities like a Ruby, Python or PHP web framework. Rather I am looking for support of the "basics" that are common for web sites. Until now, I have found only one piece of software that fulfills these requirements but while it's free, it's not open source: BoltWire at http://www.boltwire.com/. Being open source is required.

  • Specify connection timeout in java.nio

    - by miorel
    Using non-blocking I/O, the code for connecting to a remote address looks something like: SocketChannel channel = SelectorProvider.provider().openSocketChannel(); channel.configureBlocking(false); channel.connect(address); The connection process will then have to be finished by invoking finishConnect() on the channel when some selector says the corresponding key isConnectable(). Is there a way to specify the connection timeout when using this idiom?

  • Two asp.net applications to use the same membership tables - specifically user login data

    - by Lk
    HI, I have created a asp.net solution with two applications. They bothe use the same database which is setup with .net membership and roles. Application 1 uses the membership for sauthentication to an administration area - this works fine. Application 2 - has a different applicationID to App1. I want to be able to use the existing user account to manage App2's authentication needs. How is this best achieved? Do I just match App2 appliactionID to App1's or is there another way? Many Thanks, Lk

  • redoing object model construction to fit with asynchronous data fetching

    - by Andrew Patterson
    I have a modeled a set of objects that correspond with some real world concepts. TradeDrug, GenericDrug, TradePackage, DrugForm Underlying the simple object model I am trying to provide is a complex medical terminology that uses numeric codes to represent relationships and concepts, all accessible via a REST service - I am trying to hide away some of that complexity with an object wrapper. To give a concrete example I can call TradeDrug d = Searcher.FindTradeDrug("Zoloft") or TradeDrug d = new TradeDrug(34) where 34 might be the code for Zoloft. This will consult a remote server to find out some details about Zoloft. I might then call GenericDrug generic = d.EquivalentGeneric() System.Out.WriteLine(generic.ActiveIngredient().Name) in order to get back the generic drug sertraline as an object (again via a background REST call to the remote server that has all these drug details), and then perhaps find its ingredient. This model works fine and is being used in some applications that involve data processing. Recently however I wanted to do a silverlight application that used and displayed these objects. The silverlight environment only allows asynchronous REST/web service calls. I have no problems with how to make the asychhronous calls - but I am having trouble with what the design should be for my object construction. Currently the constructors for my objects do some REST calls sychronously. public TradeDrug(int code) { form = restclient.FetchForm(code) name = restclient.FetchName(code) etc.. } If I have to use async 'events' or 'actions' in order to use the Silverlight web client (I know silverlight can be forced to be a synchronous client but I am interested in asychronous approaches), does anyone have an guidance or best practice for how to structure my objects. I can pass in an action callback to the constructor public TradeDrug(int code, Action<TradeDrug> constructCompleted) { } but this then allows the user to have a TradeDrug object instance before what I want to construct is actually finished. It also doesn't support an 'event' async pattern because the object doesn't exist to add the event to until it is constructed. Extending that approach might be a factory object that itself has an asynchronous interface to objects factory.GetTradeDrugAsync(code, completedaction) or with a GetTradeDrugCompleted event? Does anyone have any recommendations?

  • Windows Azure Platform, latest version?

    - by Vimvq1987
    I searched through internet but found nothing. The whitepapers of Windows Azure Platform say something like that: In its first release, the maximum size of a single database in SQL Azure Database is 10 gigabytes A few things are omitted in the technology’s first release, however, such as the SQL Common Language Runtime (CLR) and support for spatial data. (Microsoft says that both will be available in a future version.) I want to know that Microsoft had updated Windows Azure Platform and removed these limits or not? I decided to post this question here instead of Serverfault.com because it's more relative to programming than administration. Thank you

  • General Questions on setting up Subversion (w/Netbeans) and web development workflow.

    - by Roeland
    Hey guys, I am web developer who currently works mostly on his own but, some projects require outside coding help (my brother.) Anyway, after running in to the problem of "working on the same files" and "saving over each others edits" I decided to research ways to avoid this. Through the help of stackoverflow I decided on subversion. My setup is the following: A windows 2008 server with a clean install. My desktop which is on the local network of the server. Then my brothers desktop which is at his house, not on lan. We both prefer to use netbeans for development. My Questions: How do we set this thing up correctly and most optimally. Here is my current setup and work flow. dev site: in the past I just created sub domains with my web host for test sites (company1.bythepixel.com, company2.bythepixel.com), and editted those sites with netbeans set up having remote sources (ftp). how do i set up my netbeans now? should I set it up with remote sources? I guess I may need to set up a web server on my local server. I'm just not sure of the work flow. When i hit save in netbeans.. will it update the repository.. then do i need to update the site from the repository somehow? live site: when going live, i would just copy all the files from the dev site into the live site. from what i gather i should be able to update the site from the dev repository? Currently I am toying with virtualsvn server (http://www.visualsvn.com/server/) on my local server. It looks like it is set up to use the http protocol. Is there advantages to this or should I consider something that does the file//. Do you recommend any other subversion software that would run on my 2008 box? how will my brother connect? should i set up a permanent vpn from his house to mine? suggestions? (not that important) how do I deal with databases, there anyway to do subversion on database? I know I have a lot of questions and I am trying to read / make sense of the free online subversion book, but its all so overwhelming! Wish there was a small subversion for dummies guide :)

  • PostgreSQL cross server query?

    - by AlexRednic
    Is there a way that I might query a database located on "Server 2" and get my data in "Server 1" ? That is return a set of records from a remote server to my local one. PS: Not cross database query on same server because I know how to do that with dblink.

  • Unable to add SSH pub key for GitHub

    - by Kaushik
    I am trying to set up a new GitHub account as part of learning ruby on rails. My OS is windows. I am having the following problem while trying to add my public key to the GitHub SSH public keys. When I put the key in the text area, supply a name, and click 'Add Key', I am taken to the Job profile page without any confirmation that the key has been added.(I am using SSH client GUI to generate RSA keys). When I come back to the SSH public keys page, I see that the key is not there. I tried this multiple times...without any result. Just as a test, I tried to ssh to the GitHub account using 'ssh -v [email protected]' and here is the verbose output: OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007 debug1: Connecting to github.com [207.97.227.239] port 22. debug1: Connection established. debug1: identity file /c/Users/Administrator/.ssh/identity type -1 debug1: identity file /c/Users/Administrator/.ssh/id_rsa type -1 debug1: identity file /c/Users/Administrator/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.1p1 Debian-5github2 debug1: match: OpenSSH_5.1p1 Debian-5github2 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_4.6 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-cbc hmac-md5 none debug1: kex: client->server aes128-cbc hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host 'github.com' is known and matches the RSA host key. debug1: Found key in /c/Users/Administrator/.ssh/known_hosts:1 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /c/Users/Administrator/.ssh/identity debug1: Trying private key: /c/Users/Administrator/.ssh/id_rsa debug1: Trying private key: /c/Users/Administrator/.ssh/id_dsa debug1: No more authentication methods to try.

  • How can I create a new branch in git from an existing file tree?

    - by pkaeding
    I am looking to add an existing file tree to a git repository as a new branch (I can't just copy the existing tree into my git tree, since the existing tree is versioned under a different VCS, and I am trying to sync them up). Is this possible? EDIT: Would setting up a new git repository, that is connected to the existing remote repository, and then moving the resulting .git folder work? That seems really hackish, but if that's the way to do it...

    Hi all, I try to send a request to my server via GET, but qooxdoo sends request as OPTIONS. Is any way to change this behaviour? I try to use qx.data.store.Json (url) and qx.io.remote.Request (url, "GET", type) but result is same in both cases. My version of qooxdoo is 1.0.1, browsers are FF 3.5.6 and Chromium 5.0.361.

  • How can I determine which taskbar application/windows are requesting user attention

    - by Frederic
    I'd like to know how to get a list of the windows requiring user attention from the Windows taskbar. Windows requiring attention appear with a flashing orange color within the Windows taskbar. Un-focused MSN Messenger conversation windows are a good example of this behavior: they turn orange as soon as a remote user sends an instance message. My code targets the Windows 7 platform, but working on older Windows OS would be nice too.

  • From admin to dev [closed]

    - by Terry
    Recently a friend of mine had gone from a high level NOC position to a developer. Before that he was just doing the help desk stuff. He has no degree, only the usual MIS/networking certifications and as far as I know only tinkers with code on the weekends. I can see where in some scenarios having a good understanding of configurations, packets, users, OU's, etc would be extremely beneficial to a developer. My question is this, how many full time developers started off this way? Even how many people dual wield the responsibility of developer/systems administrator/network administration?

  • how to upgrade phing 'stable' to phing 'trunk' to use SSHTask

    - by Jorre
    phing 2.4.1 (current stable version) doesn't have an SSH Task to do remote scripting. In the current trunk version, there is a SSH Task that we would like to use. How can I upgrade my current phing installation (2.4.1) to the latest build? Can I use pear for that without breaking my current phing install? Or would it be better to download only the SSH Task and add that file manually to the stable phing install?

  • Git repo planning questions

    - by masonk
    At work, development uses perforce to handle code sharing. I won't say "revision control", because we aren't allowed to check in changes until they are ready for regression testing. In order to get my personal change sets under revision control, I've been given the go-ahead to build my own git and initialize the client view of the perforce depot as a git repo. There are some difficulties in doing this, however. The client view lives in a subfolder of ~, (~/p4), and I want to put ~ under revision control as well, with its own separate history. I can't figure out how to keep the history for ~ separate from ~/p4 without using a submodule. The problem with a submodule is that it looks like I have to go make a repository that will become the submodule and then git submodule add <repo> <path>. But there is nowhere to make the submodule's repository except in ~. There seems to be no safe place to create the initial client view of the depot with git p4 clone. (I'm working off of the assumption that initing or cloning a repo into a subdirectory of a git repo is not supported. At least, I can find nothing authoritative on nested git repos.) edit: Is merely ignoring ~/p4 in the repo rooted at ~ enough to allow me to init a nested repo in ~/p4? My __git_ps1 function still thinks I'm in a git repository when I visit an ignored subdirectory of a git repo, so I'm inclined to think not. I need the "remote" repository created by git p4 sync to be a branch in ~/p4. We are required to keep all of our code in ~/p4 so that it doesn't get backed up. Can I pull from a "remote" branch that is really a local branch? This one is just for convenience, but I thought I could learn something by asking it. For 99% of the project, I just want to start the with the p4 head revision as the inital commit object. For the other 1%, I would like to suck down the entire p4 history so that I can browse it in git. IOW, after I'm done initalizing it, the initial commit of remotes/p4/master branch will contain: revision 1 of //depot/prod/Foo/Bar/* revision X of other files in //depot/prod/*, where X is the head revision and the remotes/p4/master branch contains Y commits, where Y is the number of changelists that had a file in //depot/prod/Foo/Bar/*, with each commit in the history corresponding to one of those p4 changelists, and HEAD looking like p4's head.

  • Using C# and VB.NET in one solution

    - by Younes
    I'm busy on a small project to convert an Access2003 db to .NET. I am trying to integrate my functionality in an excisting project that is being used for Administration of some kind. The code in this project is vb.net. I started by setting up my Data Access Layer, which seems to work fine. I can make new web pages that acces the data I need. However when i start to use class files to set up my Business Logic Layer i can't build my project when using C# instead of VB. I Dislike VB and like to program in C# as i know the syntax alot better etc. Is it possible to program using C# knowing that VB.NET was the language chosen to buold the entire project on? If not, what will be the smartest way to integrate my module into the project using my favorite programming language? (Make a project and reference to the dll?)

  • Cloud computing?

    - by Shawn H
    I'm an analyst and intermediate programmer working for a consulting company. Sometimes we are doing some intensive computing in Excel which can be frustrating because we have slow computers. My company does not have enough money to buy everyone new computers right now. Is there a cloud computing service that allows me to login to a high performance virtual computer from remote desktop? We are not that technical so preferrably the computer is running Windows and I can run Excel and other applications from this computer. Thanks
