• How to skip to next iteration in jQuery.each() util?

  - by Josh

  I'm trying to iterate through an array of elements. jQuery's documentation says: jquery.Each() documentation Returning non-false is the same as a continue statement in a for loop, it will skip immediately to the next iteration. I've tried calling 'return non-false;' and 'non-false;' (sans return) neither of which skip to the next iteration. Instead, they break the loop. What am i missing?

• Auto generation of Web Service sample, help and documentation

  - by orjan

  We're using javax.jws.WebServices deployed in a Glassfish server, is there a way to auto generate documentation like the one ASMX services generates? ASMX services display methods in service ASMX services when running locally could be easily tested with a prebuilt form ASMX services provided a sample request and response XML message http://keithelder.net/blog/archive/2008/01/15/How-to-Get-Around-WCFs-Lack-of-a-Preview-Web.aspx In Glasshfish together with /test/TestApi?wsdl there's /test/TestApi?Tester but it doesn't work, I don't know if it can be used to provide similar features as above?

• How to wire a verifier to a 2.0m5 Restlet using the spring extension and an xml config?

  - by Kevin Pauli

  I can't seem to find any example of how to do this. Imperatively in java it would be a piece of cake of course, but I can't seem to figure out how to inject my JaasVerifier into my SpringComponent declaratively from within the xml. It appears from the method signatures that Verifier is designed to be attached to Context, but the instance of Context itself is created as a side effect of the SpringComponent creation so I can't get a hold of it in Spring. There must be something I am missing.

• Help with cake controllers

  - by adam

  We had an outsourced engineer work on a quick feature DELETING items listed in our database. He says that the code is difficult because the "controller" is missing. Is there a pre-loaded controller for every function like that in cake, or is it weird that he is expecting a controller to be there for a feature we didn't have yet.

• How do I use multiple where clauses in GHCi?

  - by T.R.

  I'm playing around with GHCi for the first time, and I'm having some trouble writing multi-line functions. My code is as follows: Prelude> :{ Prelude| let diffSquares lst = abs $ squareOfSums lst - sumOfSquares lst Prelude| where Prelude| squareOfSums lst = (fst (sumsAndSquares lst))^2 Prelude| sumOfSquares lst = snd (sumsAndSquares lst) Prelude| sumsAndSquares = foldl (\(sms,sqrs) x -> (sms+x,sqrs+x^2)) (0,0) Prelude| :} It gives the following error: <interactive>:1:142: parse error on input `=' Could someone kindly point me in the direction of what I'm missing?

• Why Emacs/Vim/Textmate? Isn't Xcode good enough?

  - by ivanTheTerrible

  Hi I mostly do C++, Objective-C programming. And I found Xcode plus an auto completion/macro plugin (Completion Dictionary) quite adequate. However, all people seem to praise over their pure text editors. I tried Textmate for a bit; liked its simplicity but dislike its files/framework handling. Am I missing something here? Or, do Vim or Emacs have auto-completion as good as Xcode?

• What is the most useful programming language that no one is using?

  - by dbyrne

  What language do you find incredibly useful that no one else seems to care about? I am not looking for the language with the coolest features, but the language that makes you the most productive. I realize that a productive language that no one uses is a bit of an oxymoron. My personal choice would probably be ruby without rails, but I am sure others can come up with some better answers.

• inner div invisible with jquery

  - by Demiurg

  I'm using JQuery tabs to implement a very simple tabbed web site design. It works OK, unless I define another div inside every pane's div - this inner div is always invisible, i.e. display:none. I can probably hack it to make it work, but maybe I'm missing something. Is it how JQuery supposed to work ?

• Experiences with D-programming-language

  - by Dario

  Has someone here ever had experience with the D programming language? It seems to have many nice features but will it ever reach the popularity of those currently widespread languages like C++, Java or C#? So is it worth learning or is it an isolated language with minor prospects.

• Passing values from UIButton to an UIActionSheet

  - by Michael

  I'm trying to send an ActionSheet a variable from a button. I can't use the tag property because its being used for something else. I've declared myIndexRow as an instance variable and have: NSInteger myIndexRow = indexPath.row; [deleteButton addTarget:self action:@selector(showDeleteSheet:) forControlEvents:UIControlEventTouchUpInside]; deleteButton.myIndexRow = myIndexRow; but I'm getting the 'Request for member 'myRow' is something not a structure or union' There is something obvious I am missing here.

  - by Scott Davies

  Hi, The Business Application Template in Silverlight 4.0 generates authentication and user management (add user) features. Where is the info stored ? I presume it goes back to the server and then I have my pick on the server side - AD, LDAP, SQL Server, etc. ? Is this correct ? Thanks, Scott

• Numpy: Creating a complex array from 2 real ones?

  - by Duncan Tait

  I swear this should be so easy... Why is it not? :( In fact, I want to combine 2 parts of the same array to make a complex array: Data[:,:,:,0] , Data[:,:,:,1] These don't work: x = np.complex(Data[:,:,:,0], Data[:,:,:,1]) x = complex(Data[:,:,:,0], Data[:,:,:,1]) Am I missing something? Does numpy not like performing array functions on complex numbers? Here's the error: TypeError: only length-1 arrays can be converted to Python scalars Cheers

• Need to place a floating modeless form over excel main window (quasi-task pane)

  - by code4life

  Hi I need to emulate a task pane by floating a modeless form over the Excel main window. The reason for this requirement is that I need to have taskpane features for my Excel 2003 add-in, but cannot use the document-centric model. Can anyone suggest what would be the best way to do this? The modeless form would need to detect the main window resize event and resize itself accordingly, and also need to always position itself at the bottom of the window (kind of like a docking pane).

• Which Java version do you mostly (have to) work with?

  - by ferdystschenko

  While from version 5 on, Java provides many extremely useful features like annotations, enums, generics, etc., 1.4 is still in use in many enterprise projects. So I'm wondering what the chances are that you still have to work with 1.4, thus being forced to go without JPA, EJB3 etc. In your answer, please also state the branch of company you work for. Which are the reasons for not switching to Java 5? Thanks, Armin

  In Lucene, using a Standard Analyzer, I want to make fields with spaces and special characters(underscore,!,@,#,....) searchable. I set IndexField to NOT_ANALYZED_NO_NORMS and Field.Store.YES When I look at my index in LUKE, the fields are as I expected, a value such as: 'SKU Number', yet when I search for 'SKU' or 'SKU*' nothing comes up. What am I missing?

• How to handle environment-specific application configuration organization-wide?

  - by Stuart Lange

  Problem Your organization has many separate applications, some of which interact with each other (to form "systems"). You need to deploy these applications to separate environments to facilitate staged testing (for example, DEV, QA, UAT, PROD). A given application needs to be configured slightly differently in each environment (each environment has a separate database, for example). You want this re-configuration to be handled by some sort of automated mechanism so that your release managers don't have to manually configure each application every time it is deployed to a different environment. Desired Features I would like to design an organization-wide configuration solution with the following properties (ideally): Supports "one click" deployments (only the environment needs to be specified, and no manual re-configuration during/after deployment should be necessary). There should be a single "system of record" where a shared environment-dependent property is specified (such as a database connection string that is shared by many applications). Supports re-configuration of deployed applications (in the event that an environment-specific property needs to change), ideally without requiring a re-deployment of the application. Allows an application to be run on the same machine, but in different environments (run a PROD instance and a DEV instance simultaneously). Possible Solutions I see two basic directions in which a solution could go: Make all applications "environment aware". You would pass the environment name (DEV, QA, etc) at the command line to the app, and then the app is "smart" enough to figure out the environment-specific configuration values at run-time. The app could fetch the values from flat files deployed along with the app, or from a central configuration service. Applications are not "smart" as they are in #1, and simply fetch configuration by property name from config files deployed with the app. The values of these properties are injected into the config files at deploy-time by the install program/script. That install script takes the environment name and fetches all relevant configuration values from a central configuration service. Question How would/have you achieved a configuration solution that solves these problems and supports these desired features? Am I on target with the two possible solutions? Do you have a preference between those solutions? Also, please feel free to tell me that I'm thinking about the problem all wrong. Any feedback would be greatly appreciated.

• SSL Authentication with Certificates: Should the Certificates have a hostname?

  - by sixtyfootersdude

  Summary JBoss allows clients and servers to authenticate using certificates and ssl. One thing that seems strange is that you are not required to give your hostname on the certificate. I think that this means if Server B is in your truststore, Sever B can pretend to be any server that they want. (And likewise: if Client B is in your truststore...) Am I missing something here? Authentication Steps (Summary of Wikipeida Page) Client Server ================================================================================================= 1) Client sends Client Hello ENCRIPTION: None - highest TLS protocol supported - random number - list of cipher suites - compression methods 2) Sever Hello ENCRIPTION: None - highest TLS protocol supported - random number - choosen cipher suite - choosen compression method 3) Certificate Message ENCRIPTION: None - 4) ServerHelloDone ENCRIPTION: None 5) Certificate Message ENCRIPTION: None 6) ClientKeyExchange Message ENCRIPTION: server's public key => only server can read => if sever can read this he must own the certificate - may contain a PreMasterSecerate, public key or nothing (depends on cipher) 7) CertificateVerify Message ENCRIPTION: clients private key - purpose is to prove to the server that client owns the cert 8) BOTH CLIENT AND SERVER: - use random numbers and PreMasterSecret to compute a common secerate 9) Finished message - contains a has and MAC over previous handshakes (to ensure that those unincripted messages did not get broken) 10) Finished message - samething Sever Knows The client has the public key for the sent certificate (step 7) The client's certificate is valid because either: it has been signed by a CA (verisign) it has been self-signed BUT it is in the server's truststore It is not a replay attack because presumably the random number (step 1 or 2) is sent with each message Client Knows The server has the public key for the sent certificate (step 6 with step 8) The server's certificate is valid because either: it has been signed by a CA (verisign) it has been self-signed BUT it is in the client's truststore It is not a replay attack because presumably the random number (step 1 or 2) is sent with each message Potential Problem Suppose the client's truststore has certs in it: Server A Server B (malicous) Server A has hostname www.A.com Server B has hostname www.B.com Suppose: The client tries to connect to Server A but Server B launches a man in the middle attack. Since server B: has a public key for the certificate that will be sent to the client has a "valid certificate" (a cert in the truststore) And since: certificates do not have a hostname feild in them It seems like Server B can pretend to be Server A easily. Is there something that I am missing?

• How can I tell [G]vim where to look for python26.dll?

  I have a version of Vim compiled with python 2.6 support enabled (from here). however vim cannot find the python26.dll. :version confirms +python/dyn :version and gvim.exe confirms DYNAMIC_PYTHON_DLL="python26.dll" echo PATH confirms python26.dll is in the search path. (both c:\windows\system32, and C:\python26) What could I be missing? Did I skip something silly?
