• Very very slow transfer speeds between Windows 7 and samba server running on Ubuntu 11.10/12.04 minimal

  - by kuzyt

  As mentioned in the title I tried transferring files between Windows 7 and the samba server running on both Ubuntu 11.10 and 12.04 but both showed very slow transfer speeds. Can someone please guide me in the right direction to debug this problem ? wget --output-document=/dev/null http://tokyo1.linode.com/100MB-tokyo.bin --2012-08-21 22:02:17-- http://tokyo1.linode.com/100MB-tokyo.bin Resolving tokyo1.linode.com (tokyo1.linode.com)... 106.187.33.12 Connecting to tokyo1.linode.com (tokyo1.linode.com)|106.187.33.12|:80... connected.

• A Generic, IDisposable WCF Service Client

  - by Steve Wilkes

  WCF clients need to be cleaned up properly, but as they're usually auto-generated they don't implement IDisposable. I've been doing a fair bit of WCF work recently, so I wrote a generic WCF client wrapper which effectively gives me a disposable service client. The ServiceClientWrapper is constructed using a WebServiceConfig instance, which contains a Binding, an EndPointAddress, and whether the client should ignore SSL certificate errors - pretty useful during testing! The Binding can be created based on configuration data or entirely programmatically - that's not the client's concern. Here's the service client code: using System; using System.Net; using System.Net.Security; using System.ServiceModel; public class ServiceClientWrapper<TService, TChannel> : IDisposable     where TService : ClientBase<TChannel>     where TChannel : class {     private readonly WebServiceConfig _config;     private TService _serviceClient;     public ServiceClientWrapper(WebServiceConfig config)     {         this._config = config;     }     public TService CreateServiceClient()     {         this.DisposeExistingServiceClientIfRequired();         if (this._config.IgnoreSslErrors)         {             ServicePointManager.ServerCertificateValidationCallback =                 (obj, certificate, chain, errors) => true;         }         else         {             ServicePointManager.ServerCertificateValidationCallback =                 (obj, certificate, chain, errors) => errors == SslPolicyErrors.None;         }         this._serviceClient = (TService)Activator.CreateInstance(             typeof(TService),             this._config.Binding,             this._config.Endpoint);         if (this._config.ClientCertificate != null)         {             this._serviceClient.ClientCredentials.ClientCertificate.Certificate =                 this._config.ClientCertificate;         }         return this._serviceClient;     }     public void Dispose()     {         this.DisposeExistingServiceClientIfRequired();     }     private void DisposeExistingServiceClientIfRequired()     {         if (this._serviceClient != null)         {             try             {                 if (this._serviceClient.State == CommunicationState.Faulted)                 {                     this._serviceClient.Abort();                 }                 else                 {                     this._serviceClient.Close();                 }             }             catch             {                 this._serviceClient.Abort();             }             this._serviceClient = null;         }     } } A client for a particular service can then be created something like this: public class ManagementServiceClientWrapper :     ServiceClientWrapper<ManagementServiceClient, IManagementService> {     public ManagementServiceClientWrapper(WebServiceConfig config)         : base(config)     {     } } ...where ManagementServiceClient is the auto-generated client class, and the IManagementService is the auto-generated WCF channel class - and used like this: using(var serviceClientWrapper = new ManagementServiceClientWrapper(config)) {     serviceClientWrapper.CreateServiceClient().CallService(); } The underlying WCF client created by the CreateServiceClient() will be disposed after the using, and hey presto - a disposable WCF service client.

• Calling Web Services using ADF 11g

  - by James Taylor

  One of the benefits of ADF is that fact that it can use multiple data sources. With SOA playing a big part in today’s IT landscape, applications need to be able to utilise this SOA framework to leverage functionality from multiple systems to provide a composite application. ADF provides functionality to expose web services via the ADF Business Component so if you know how to use Business Components for a database. Configuring ADF for web services is much the same. In this example I use an OSB web service that gets a customer. Create a new Fusion Web Application (ADF) Application and click OK    Provide an Application Name, GetCustomerADF and click Next    From the Project Technologies move Web Services into the Selected box. Accept the defaults and click Finish. Right-click the Model project and select New In the Gallery select Web Services –> Web Service Data Control then click OK. Provide a name GetCustomerDC and give the URL endpoint for the Web Service, then click Next Select the web service operation you want to use for the ADF application. In my example my web service only has one operation. Click Finish Save your work, File –> Save The data control has now been created, the next steps create the UI components. In your application created in step 1 find the ViewController project, right-click and choose New In the Gallery select JSF –> JSF Page Provide a name for the jsp page, GetCustomer, Also ensure that the ‘Create as XML Document (*.jsp) check box is checked. I have selected the page template, Oracle Three Column Layout but you can create a layout of your choice. I only want 2 columns so I delete the last column but right-clicking the right had panel and selecting Delete Drag the fields you require from the web service data control to the left pannel. In my example I only require the Customer ID. When you drag to the panel select Texts –>ADF Input Text w/Label In this example I want to search on a customer based on the ID. So Once I select the ID I want to execute the request. To do this I need a button. Drag the operation object under the fields created in step 15. Select Methods –> ADF Button. You now need to provide the mappings, Choose the ‘Show EI Expression Builder’ Navigate to the bindings, ADFBindings –> bindings –> parametersIterator –> currentRow Click OK Drag and drop the return information I just want the results shown in a form. I want to show all fields Now it is time to test, Right-click the jspx page created in steps 11 – 21 and select Run A browser should start, enter valid values and test

• Access Control Service: Protocol and Token Transition

  - by Your DisplayName here!

  ACS v2 supports a number of protocols (WS-Federation, WS-Trust, OpenId, OAuth 2 / WRAP) and a number of token types (SWT, SAML 1.1/2.0) – see Vittorio’s Infographic here. Some protocols are designed for active client (WS-Trust, OAuth / WRAP) and some are designed for passive clients (WS-Federation, OpenID). One of the most obvious advantages of ACS is that it allows to transition between various protocols and token types. Once example would be using WS-Federation/SAML between your application and ACS to sign in with a Google account. Google is using OpenId and non-SAML tokens, but ACS transitions into WS-Federation and sends back a SAML token. This way you application only needs to understand a single protocol whereas ACS acts as a protocol bridge (see my ACS2 sample here). Another example would be transformation of a SAML token to a SWT. This is achieved by using the WRAP endpoint – you send a SAML token (from a registered identity provider) to ACS, and ACS turns it into a SWT token for the requested relying party, e.g. (using the WrapClient from Thinktecture.IdentityModel): [TestMethod] public void GetClaimsSamlToSwt() {     // get saml token from idp     var samlToken = Helper.GetSamlIdentityTokenForAcs();     // send to ACS for SWT converion     var swtToken = Helper.GetSimpleWebToken(samlToken);     var client = new HttpClient(Constants.BaseUri);     client.SetAccessToken(swtToken, WebClientTokenSchemes.OAuth);     // call REST service with SWT     var response = client.Get("wcf/client");     Assert.AreEqual<HttpStatusCode>(HttpStatusCode.OK, response.StatusCode); } There are more protocol transitions possible – but they are not so obvious. A popular example would be how to call a REST/SOAP service using e.g. a LiveId login. In the next post I will show you how to approach that scenario.

• Enhance Your Browsing with Hyperwords in Firefox

  - by Asian Angel

  While browsing it is easy to find information that you would like to know more about, convert, or translate. The Hyperwords extension provides access to these types of resources and more in Firefox. Using Hyperwords Once the extension has finished installing you will be presented with a demo video that will let you learn more about how Hyperwords works. For our first example we chose to look for more information concerning “WASP-12b” using Wikipedia. Notice the small bluish circle on the lower right of the highlighted term…it is the default access for the Hyperwords menu (access by hovering mouse over it). If you hover over the the Wikipedia (or other) link you can access the information in a scrollable popup window. Or if you prefer click on the link to view the information in a new tab. Choose the style that best suits your needs. Hyperwords is extremely useful for quick unit conversions. Suppose you want to share a news story that you have found while browsing. Highlight the title, access Hyperwords, and choose your preferred sharing source. You may need to authorize access for Hyperwords to post to your account. Once you have authorized access you can start sharing those links very easily. This is just a small sampling of Hyperwords many useful features. Preferences Hyperwords has a nice set of preferences available to help you customize it. Alter the menu popup style, add or remove menu entries, and modify other functions for Hyperwords. Conclusion Hyperwords makes a nice addition to Firefox for anyone needing quick access to search, reference, translation, and other services while browsing.

• Thinktecture.IdentityServer RC

  - by Your DisplayName here!

  I just uploaded the RC of IdentityServer to Codeplex. This release is feature complete and if I don’t get any bug reports this is also pretty much the final V1. Changes from B1 The configuration data access is now based on EF 4.1 code first. This makes it much easier to use different data stores. For RTM I will also provide a SQL script for SQL Server so you can move the configuration to a separate machine (e.g. for load balancing scenarios). I included the ASP.NET Universal Providers in the download. This adds official support for SQL Azure, SQL Server and SQL Compact for the membership, roles and profile features. Unfortunately the Universal Provider use a different schema than the original ASP.NET providers (that sucks btw!) – so I made them optional. If you want to use them go to web.config and uncomment the new provider. The relying party registration entries now have added fields to add extra data that you want to couple with the RP. One use case could be to give the UI a hint how the login experience should look like per RP. This allows to have a different look and feel for different relying parties. I also included a small helper API that you can use to retrieve the RP record based on the incoming WS-Federation query string. WS-Federation single sign out is now conforming to the spec. Certificate based endpoint identities for SSL endpoints are optional now. Added a initial configuration “wizard”. This sets up the signing certificate, issuer URI and site title on the first run. Installation This is still a “developer” release – that means it ships with source code that you have to build it etc. But from that point it should be a little more straightforward as it used to be: Make sure SSL is configured correctly for IIS Map the WebSite directory to a vdir in IIS Run the web site. This should bring up the initial configuration Make sure the worker process account has access to the signing certificate private key Make sure all your users are in the “IdentityServerUsers” role in your role store. Administrators need the “IdentityServerAdministrators” role That should be it. A proper documentation will be hopefully available soon (any volunteers?). Please provide feedback! thanks!

• WNA Configuration in OAM 11g

  - by P Patra

  Pre-Requisite: Kerberos authentication scheme has to exist. This is usually pre-configured OAM authentication scheme. It should have Authentication Level - "2", Challenge Method - "WNA", Challenge Direct URL - "/oam/server" and Authentication Module- "Kerberos". The default authentication scheme name is "KerberosScheme", this name can be changed. The DNS name has to be resolvable on the OAM Server. The DNS name with referrals to AD have to be resolvable on OAM Server. Ensure nslookup work for the referrals. Pre-Install: AD team to produce keytab file on the AD server by running ktpass command. Provide OAM Hostname to AD Team. Receive from AD team the following: Keypass file produced when running the ktpass command ktpass username ktpass password Copy the keytab file to convenient location in OAM install tree and rename the file if desired. For instance where oam-policy.xml file resides. i.e. /fa_gai2_d/idm/admin/domains/idm-admin/IDMDomain/config/fmwconfig/keytab.kt Configure WNA Authentication on OAM Server: Create config file krb.config and set the environment variable to the path to this file: KRB_CONFIG=/fa_gai2_d/idm/admin/domains/idm-admin/IDMDomain/config/fmwconfig/krb.conf The variable KRB_CONFIG has to be set in the profile for the user that OAM java container(i.e. Wbelogic Server) runs as, so that this setting is available to the OAM server. i.e. "applmgr" user. In the krb.conf file specify: [libdefaults] default_realm= NOA.ABC.COM dns_lookup_realm= true dns_lookup_kdc= true ticket_lifetime= 24h forwardable= yes [realms] NOA.ABC.COM={ kdc=hub21.noa.abc.com:88 admin_server=hub21.noa.abc.com:749 default_domain=NOA.ABC.COM [domain_realm] .abc.com=ABC.COM abc.com=ABC.COM .noa.abc.com=NOA.ABC.COM noa.abc.com=NOA.ABC.COM Where hub21.noa.abc.com is load balanced DNS VIP name for AD Server and NOA.ABC.COM is the name of the domain. Create authentication policy to WNA protect the resource( i.e. EBSR12) and choose the "KerberosScheme" as authentication scheme. Login to OAM Console => Policy Configuration Tab => Browse Tab => Shared Components => Application Domains => IAM Suite => Authentication Policies => Create Name: ABC WNA Auth Policy Authentication Scheme: KerberosScheme Failure URL: http://hcm.noa.abc.com/cgi-bin/welcome Edit System Configuration for Kerberos System Configuration Tab => Access Manager Settings => expand Authentication Modules => expand Kerberos Authentication Module => double click on Kerberos Edit "Key Tab File" textbox - put in /fa_gai2_d/idm/admin/domains/idm-admin/IDMDomain/config/fmwconfig/keytab.kt Edit "Principal" textbox - put in HTTP/[email protected] Edit "KRB Config File" textbox - put in /fa-gai2_d/idm/admin/domains/idm-admin/IDMDomain/config/fmwconfig/krb.conf Cilck "Apply" In the script setting environment for the WLS server where OAM is deployed set the variable: KRB_CONFIG=/fa_gai2_d/idm/admin/domains/idm-admin/IDMDomain/config/fmwconfig/krb.conf Re-start OAM server and OAM Server Container( Weblogic Server)

• JWT Token Security with Fusion Sales Cloud

  - by asantaga

  When integrating SalesCloud with a 3rd party application you often need to pass the users identity to the 3rd party application so that  The 3rd party application knows who the user is The 3rd party application needs to be able to do WebService callbacks to Sales Cloud as that user.  Until recently without using SAML, this wasn't easily possible and one workaround was to pass the username, potentially even the password, from Sales Cloud to the 3rd party application using URL parameters.. With Oracle Fusion R8 we now have a proper solution and that is called "JWT Token support". This is based on the industry JSON Web Token standard , for more information see here JWT Works by allowing the user the ability to generate a token (lasts a short period of time) for a specific application. This token is then passed to the 3rd party application as a GET parameter.  The 3rd party application can then call into SalesCloud and use this token for all webservice calls, the calls will be executed as the user who generated the token in the first place, or they can call a special HR WebService (UserService-findSelfUserDetails() ) with the token and Fusion will respond with the users details. Some more details  The following will go through the scenario that you want to embed a 3rd party application within a WebContent frame (iFrame) within the opportunity screen.  1. Define your application using the topology manager in setup and maintenance  See this documentation link on topology manager 2. From within your groovy script which defines the iFrame you wish to embed, write some code which looks like this : def thirdpartyapplicationurl = oracle.topologyManager.client.deployedInfo.DeployedInfoProvider.getEndPoint("My3rdPartyApplication" )def crmkey= (new oracle.apps.fnd.applcore.common.SecuredTokenBean().getTrustToken())def url = thirdpartyapplicationurl +"param1="+OptyId+"&jwt ="+crmkeyreturn (url)  This snippet generates a URL which contains The Hostname/endpoint of the 3rd party application Two Parameters The opportunityId stored in parameter "param1" The JWT Token store in  parameter "jwt" 3. From your 3rd Party Application you now have two options Execute a webservice call by first setting the header parameter "Authentication" to the JWT token. The webservice call will be executed against Fusion Applications "As" the user who execute the process To find out "Who you are" , set the header parameter to "Authentication" and execute the special webservice call findSelfUserDetails(), in the UserDetailsService For more information  Oracle Sales Cloud Documentation , specific chapter on JWT Token OTN samples, specifically the Rich UI With JWT Token Sample Oracle Fusion Applications General Documentation

• const vs. readonly for a singleton

  - by GlenH7

  First off, I understand there are folk who oppose the use of singletons. I think it's an appropriate use in this case as it's constant state information, but I'm open to differing opinions / solutions. (See The singleton pattern and When should the singleton pattern not be used?) Second, for a broader audience: C++/CLI has a similar keyword to readonly with initonly, so this isn't strictly a C# type question. (Literal field versus constant variable in C++/CLI) Sidenote: A discussion of some of the nuances on using const or readonly. My Question: I have a singleton that anchors together some different data structures. Part of what I expose through that singleton are some lists and other objects, which represent the necessary keys or columns in order to connect the linked data structures. I doubt that anyone would try to change these objects through a different module, but I want to explicitly protect them from that risk. So I'm currently using a "readonly" modifier on those objects*. I'm using readonly instead of const with the lists as I read that using const will embed those items in the referencing assemblies and will therefore trigger a rebuild of those referencing assemblies if / when the list(s) is/are modified. This seems like a tighter coupling than I would want between the modules, but I wonder if I'm obsessing over a moot point. (This is question #2 below) The alternative I see to using "readonly" is to make the variables private and then wrap them with a public get. I'm struggling to see the advantage of this approach as it seems like wrapper code that doesn't provide much additional benefit. (This is question #1 below) It's highly unlikely that we'll change the contents or format of the lists - they're a compilation of things to avoid using magic strings all over the place. Unfortunately, not all the code has converted over to using this singleton's presentation of those strings. Likewise, I don't know that we'd change the containers / classes for the lists. So while I normally argue for the encapsulations advantages a get wrapper provides, I'm just not feeling it in this case. A representative sample of my singleton public sealed class mySingl { private static volatile mySingl sngl; private static object lockObject = new Object(); public readonly Dictionary<string, string> myDict = new Dictionary<string, string>() { {"I", "index"}, {"D", "display"}, }; public enum parms { ABC = 10, DEF = 20, FGH = 30 }; public readonly List<parms> specParms = new List<parms>() { parms.ABC, parms.FGH }; public static mySingl Instance { get { if(sngl == null) { lock(lockObject) { if(sngl == null) sngl = new mySingl(); } } return sngl; } } private mySingl() { doSomething(); } } Questions: Am I taking the most reasonable approach in this case? Should I be worrying about const vs. readonly? is there a better way of providing this information?

• Find a Faster DNS Server with Namebench

  - by Mysticgeek

  One way to speed up your Internet browsing experience is using a faster DNS server. Today we take a look at Namebench, which will compare your current DNS server against others out there, and help you find a faster one. Namebench Download the file and run the executable (link below). Namebench starts up and will include the current DNS server you have configured on your system. In this example we’re behind a router and using the DNS server from the ISP. Include the global DNS providers and the best available regional DNS server, then start the Benchmark. The test starts to run and you’ll see the queries it’s running through. The benchmark takes about 5-10 minutes to complete. After it’s complete you’ll get a report of the results. Based on its findings, it will show you what DNS server is fastest for your system. It also displays different types of graphs so you can get a better feel for the different results. You can export the results to a .csv file as well so you can present the results in Excel. Conclusion This is a free project that is in continuing development, so results might not be perfect, and there may be more features added in the future. If you’re looking for a method to help find a faster DNS server for your system, Namebench is a cool free utility to help you out.

• Rant on EDI

  - by Anthony Trudeau

  Originally posted on: http://geekswithblogs.net/tonyt/archive/2013/06/27/153261.aspxMy post this month is a rant and not something informational. I hope y'all will forgive me.It's been a slow month. I was on vacation with my daughter for the middle part of the month. And the rest of my time has been preparing for a major ERP upgrade, and dealing with a last minute surprise from a customer that has EDI changes.The subject of EDI is my rant. I was tossed into EDI years ago by the same customer. I understood the basic concepts, but not details -- implementation or otherwise. I started with my network including a couple of people with EDI experience. And for one that was all she did. She was my first taste of what seems to be a protected group.I started looking for the standards with a budget in mind, or rather a lack of budget. See whenever someone stone walls you like that it tells me that what they're doing isn't as mystical as they'd like you to believe. Real magic doesn't need to be kept secret. And that is the case with EDI; however, the EDI industry tries to protect it. You cannot even download the standards. They cost thousands of dollars.All this does is ensure that they continue to rack up consulting dollars from their ignorant clients. Well sirs and madams, I put my finger in your eye. I developed my own translator. And while it's not robust enough to resell due to the limited scope of information I could gather. It did save my employer tens if not over a hundred thousand dollars.My public service message, therefore is as follows. Don't be afraid to tackle implementing EDI if you're even a semi-competent developer. You need some experience parsing, familiarity with your business system, and a little patience. Also, pick your VAN well. Don't fall into the trap of thinking that the biggest names are the best choice. That was a costly mistake for us that we are stuck with for a couple more years.

• JDK bug migration: components and subcomponents

  - by darcy

  One subtask of the JDK migration from the legacy bug tracking system to JIRA was reclassifying bugs from a three-level taxonomy in the legacy system, (product, category, subcategory), to a fundamentally two-level scheme in our customized JIRA instance, (component, subcomponent). In the JDK JIRA system, there is technically a third project-level classification, but by design a large majority of JDK-related bugs were migrated into a single "JDK" project. In the end, over 450 legacy subcategories were simplified into about 120 subcomponents in JIRA. The 120 subcomponents are distributed among 17 components. A rule of thumb used was that a subcategory had to have at least 50 bugs in it for it to be retained. Below is a listing the component / subcomponent classification of the JDK JIRA project along with some notes and guidance on which OpenJDK email addresses cover different areas. Eventually, a separate incidents project to host new issues filed at bugs.sun.com will use a slightly simplified version of this scheme. The preponderance of bugs and subcomponents for the JDK are in library-related areas, with components named foo-libs and subcomponents primarily named after packages. While there was an overall condensation of subcomponents in the migration, in some cases long-standing informal divisions in core libraries based on naming conventions in the description were promoted to formal subcomponents. For example, hundreds of bugs in the java.util subcomponent whose descriptions started with "(coll)" were moved into java.util:collections. Likewise, java.lang bugs starting with "(reflect)" and "(proxy)" were moved into java.lang:reflect. client-libs (Predominantly discussed on 2d-dev and awt-dev and swing-dev.) 2d demo java.awt java.awt:i18n java.beans (See beans-dev.) javax.accessibility javax.imageio javax.sound (See sound-dev.) javax.swing core-libs (See core-libs-dev.) java.io java.io:serialization java.lang java.lang.invoke java.lang:class_loading java.lang:reflect java.math java.net java.nio (Discussed on nio-dev.) java.nio.charsets java.rmi java.sql java.sql:bridge java.text java.util java.util.concurrent java.util.jar java.util.logging java.util.regex java.util:collections java.util:i18n javax.annotation.processing javax.lang.model javax.naming (JNDI) javax.script javax.script:javascript javax.sql org.openjdk.jigsaw (See jigsaw-dev.) security-libs (See security-dev.) java.security javax.crypto (JCE: includes SunJCE/MSCAPI/UCRYPTO/ECC) javax.crypto:pkcs11 (JCE: PKCS11 only) javax.net.ssl (JSSE, includes javax.security.cert) javax.security javax.smartcardio javax.xml.crypto org.ietf.jgss org.ietf.jgss:krb5 other-libs corba corba:idl corba:orb corba:rmi-iiop javadb other (When no other subcomponent is more appropriate; use judiciously.)

The specification subcomponent encompasses the formal language and virtual machine specifications. specification language (The Java Language Specification) vm (The Java Virtual Machine Specification) The code for the deploy and install areas is not currently included in OpenJDK. deploy deployment_toolkit plugin webstart install auto_update install servicetags In the JDK, there are a number of cross-cutting concerns whose organization is essentially orthogonal to other areas. Since these areas generally have dedicated teams working on them, it is easier to find bugs of interest if these bugs are grouped first by their cross-cutting component rather than by the affected technology. docs doclet guides hotspot release_notes tools tutorial embedded build hotspot libraries globalization locale-data translation performance hotspot libraries The list of subcomponents will no doubt grow over time, but my inclination is to resist that growth since the addition of each subcomponent makes the system as a whole more complicated and harder to use. When the system gets closer to being externalized, I plan to post more blog entries describing recommended use of various custom fields in the JDK project.

• How to recover from finite-state-machine breakdown?

  - by Earl Grey

  My question may seems very scientific but I think it's a common problem and seasoned developers and programmers hopefully will have some advice to avoid the problem I mention in title. Btw., what I describe bellow is a real problem I am trying to proactively solve in my iOS project, I want to avoid it at all cost. By finite state machine I mean this I have a UI with a few buttons, several session states relevant to that UI and what this UI represents, I have some data which values are partly displayed in the UI, I receive and handle some external triggers (represented by callbacks from sensors). I made state diagrams to better map the relevant scenarios that are desirable and alowable in that UI and application. As I slowly implement the code, the app starts to behave more and more like it should. However, I am not very confident that it is robust enough. My doubts come from watching my own thinking and implementation process as it goes. I was confident that I had everything covered, but it was enough to make a few brute tests in the UI and I quickly realized that there are still gaps in the behavior ..I patched them. However, as each component depends and behaves based on input from some other component, a certain input from user or some external source trigers a chain of events, state changes..etc. I have several components and each behave like this Trigger received on input - trigger and its sender analyzed - output something (a message, a state change) based on analysis The problem is, this is not completely selfcontained, and my components (a database item, a session state, some button's state)...COULD be changed, influenced, deleted, or otherwise modified, outside the scope of the event-chain or desirable scenario. (phone crashes, battery is empty phone turn of suddenly) This will introduce a nonvalid situation into the system, from which the system potentially COULD NOT BE ABLE to recover. I see this (althought people do not realize this is the problem) in many of my competitors apps that are on apple store, customers write things like this "I added three documents, and after going there and there, i cannot open them, even if a see them." or "I recorded videos everyday, but after recording a too log video, I cannot turn of captions on them.., and the button for captions doesn't work".. These are just shortened examples, customers often describe it in more detail..from the descriptions and behavior described in them, I assume that the particular app has a FSM breakdown. So the ultimate question is how can I avoid this, and how to protect the system from blocking itself? EDIT I am talking in the context of one viewcontroller's view on the phone, I mean one part of the application. I Understand the MVC pattern, I have separate modules for distinct functionality..everything I describe is relevant to one canvas on the UI.

• User connection management in Reporting Services configuration

  - by Testas

  IT professionals will use Reporting Services Configuration Manager to perform post installation tasks for SQL Server Reporting Services. Introduced in SQL Server 2005, Reporting Services Configuration Manager provides an intuitive interface to perform tasks including specifying the report server database, report manager url, and indeed one of the first post installation tasks that should be performed is backing up the encryption keys that are used to protect the sensitive information within the rdl files.  Many of the options that are selected within Reporting Services Configuration Manager are written to a number of configuration files including the rsreportserver.config file located in C:\Program Files\Microsoft SQL Server\Report Server InstanceName\Reporting Services\ReportServer folder.When opening this file you will notice that there are more configuration settings within the rsreportserver.config file than is available through the Reporting Services Configuration Manager Interface. As a result there are additional configuration options that can be defined within this file.  A customer was having a problem performing stress tests against a new Report Server that would be going live for an enterprise reporting system. One aspect of the stress test was to fire 50 connections from a single user account. When performing the stress test an error described that the maximum active request had been exceeded. Within the rsreportserver.config, there is a key that is added to the file:  <Add Key=”MaxActiveReqForOneUser” Value=”20”/>  Changing the value from 20 to 50 accommodated the needs of the stress test, however, a wider question should be asked pertaining to this setting when implementing Reporting Services to a production environment. Within an intranet environment, the default setting is appropriate when network bandwidth is high, users are known and demand for reports is particularly high from a group of users.  However, when deploying a Reporting Server solution to an extranet, or the internet, you may want to consider reducing this setting to reduce to scope of connections that can be acquired by a single user and placing unnecessary pressure on the report server. I do hope that Reporting Services Configuration Manager evolves to include an advanced page that includes an intuitive interface to change configuration settings such as the MaxActiveReqForOneUser, and also configure rendering and data extensions and define secure connection levels to the report server. All these options can be configured within the rsreportserver.config file, and these are setting that customers would like to see in Reporting Services Configuration Manager in the future.   If you think that the SQL community would benefit from this addition, you can vote on it at Microsoft Connect  https://connect.microsoft.com/SQLServer/feedback/details/565575/extending-reporting-services-configuration-manager-rscm

• problem in array of shooter sprites which contain different colour bubbles

  - by prakash s

  everyone i am developing bubble shooter game in cocos2d I have placed shooter array which contain different color bubbles like this 00000000 it is 8 bubbles array if i tap the screen, first bubbles should move for shooting the target .png .And if i again tap the screen again 2nd position bubble should move for shooting the target.png bubbles,how it will possible for me because i have already created the array of target which contain different color bubbles, here i write the code : - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { // Choose one of the touches to work with UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; // Set up initial location of projectile CGSize winSize = [[CCDirector sharedDirector] winSize]; NSMutableArray * movableSprites = [[NSMutableArray alloc] init]; NSArray *images = [NSArray arrayWithObjects:@"1.png", @"2.png", @"3.png", @"4.png",@"5.png",@"6.png",@"7.png", @"8.png", nil]; for(int i = 0; i < images.count; ++i) { int index = (arc4random() % 8)+1; NSString *image = [NSString stringWithFormat:@"%d.png", index]; CCSprite*projectile = [CCSprite spriteWithFile:image]; //CCSprite *projectile = [CCSprite spriteWithFile:@"3.png" rect:CGRectMake(0, 0,256,256)]; [self addChild:projectile]; [movableSprites addObject:projectile]; float offsetFraction = ((float)(i+1))/(images.count+1); //projectile.position = ccp(20, winSize.height/2); //projectile.position = ccp(18,0 ); //projectile.position = ccp(350*offsetFraction, 20.0f); projectile.position = ccp(10/offsetFraction, 20.0f); // projectile.position = ccp(projectile.position.x,projectile.position.y); // Determine offset of location to projectile int offX = location.x - projectile.position.x; int offY = location.y - projectile.position.y; // Bail out if we are shooting down or backwards if (offX <= 0) return; // Ok to add now - we've double checked position //[self addChild:projectile]; // Determine where we wish to shoot the projectile to int realX = winSize.width + (projectile.contentSize.width/2); float ratio = (float) offY / (float) offX; int realY = (realX * ratio) + projectile.position.y; CGPoint realDest = ccp(realX, realY); // Determine the length of how far we're shooting int offRealX = realX - projectile.position.x; int offRealY = realY - projectile.position.y; float length = sqrtf((offRealX*offRealX)+(offRealY*offRealY)); float velocity = 480/1; // 480pixels/1sec float realMoveDuration = length/velocity; // Move projectile to actual endpoint [projectile runAction:[CCSequence actions: [CCMoveTo actionWithDuration:realMoveDuration position:realDest], [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)], nil]]; // Add to projectiles array projectile.tag = 1; [_projectiles addObject:projectile]; } }

• IRM and Consumerization

  - by martin.abrahams

  As the season of rampant consumerism draws to its official close on 12th Night, it seems a fitting time to discuss consumerization - whereby technologies from the consumer market, such as the Android and iPad, are adopted by business organizations. I expect many of you will have received a shiny new mobile gadget for Christmas - and will be expecting to use it for work as well as leisure in 2011. In my case, I'm just getting to grips with my first Android phone. This trend developed so much during 2010 that a number of my customers have officially changed their stance on consumer devices - accepting consumerization as something to embrace rather than resist. Clearly, consumerization has significant implications for information control, as corporate data is distributed to consumer devices whether the organization is aware of it or not. I daresay that some DLP solutions can limit distribution to some extent, but this creates a conflict between accepting consumerization and frustrating it. So what does Oracle IRM have to offer the consumerized enterprise? First and foremost, consumerization does not automatically represent great additional risk - if an enterprise seals its sensitive information. Sealed files are encrypted, and that fundamental protection is not affected by copying files to consumer devices. A device might be lost or stolen, and the user might not think to report the loss of a personally owned device, but the data and the enterprise that owns it are protected. Indeed, the consumerization trend is another strong reason for enterprises to deploy IRM - to protect against this expansion of channels by which data might be accidentally exposed. It also enables encryption requirements to be met even though the enterprise does not own the device and cannot enforce device encryption. Moving on to the usage of sealed content on such devices, some of our customers are using virtual desktop solutions such that, in truth, the sealed content is being opened and used on a PC in the normal way, and the user is simply using their device for display purposes. This has several advantages: The sensitive documents are not actually on the devices, so device loss and theft are even less of a worry The enterprise has another layer of control over how and where content is used, as access to the virtual solution involves another layer of authentication and authorization - defence in depth It is a generic solution that means the enterprise does not need to actively support the ever expanding variety of consumer devices - the enterprise just manages some virtual access to traditional systems using something like Citrix or Remote Desktop services. It is a tried and tested way of accessing sealed documents. People have being using Oracle IRM in conjunction with Citrix and Remote Desktop for several years. For some scenarios, we also have the "IRM wrapper" option that provides a simple app for sealing and unsealing content on a range of operating systems. We are busy working on other ways to support the explosion of consumer devices, but this blog is not a proper forum for talking about them at this time. If you are an Oracle IRM customer, we will be pleased to discuss our plans and your requirements with you directly on request. You can be sure that the blog will cover the new capabilities as soon as possible.

• Agile PLM Highlights from Oracle OpenWorld 2012

  - by Kerrie Foy

  Thank you to everyone who joined us at Oracle OpenWorld this year, either in person or virtually (thanks for tweeting #oowplm)!  From customer presentations to after-hours networking opportunities, there was a lot to see and do during the entire conference. Sessions It was our pleasure to feature several customer speakers during our PLM sessions at OpenWorld from such companies as Starbucks, Coca-Cola, Facebook, Eli Lilly, and many more.  Each had a unique perspective to share and fascinating insight into how they successfully leverage Agile PLM to facilitate profitable innovation, protect brand integrity, streamline operations, manage compliance, launch faster, etc.  For example, during the Product Value Chain keynote session, CIO Chris Bedi of JDSU shared how they implemented Agile PLM to support business imperatives around rapid innovation, centralizing product information, collaboration, and eliminate the “Excel gymnastics” required to obtain global portfolio visibility. In just 120 days after implementing, JDSU employees reported significant improvements around product record management, new product introduction, engineering collaboration and more, which created a better work environment to enable critical innovation. I could write on and on about the almost 20 sessions! So to spare yourselves, please visit launch.oracle.com/?plmopenworld2012; it’s a curated selection of PLM presentations from the OpenWorld Content Catalog and available on-demand. Enjoy! Agile Innovation Management During OpenWorld, we announced an exciting new addition to the Agile PLM applications called Innovation Management that redefines the industry’s scope of product lifecycle management.  Our broad vision of complete enterprise PLM for the entire Product Value Chain already broke new ground by helping organizations extend PLM disciplines downstream by connecting product design to commercialization processes; now we are helping executives look farther upstream in the early innovation phases to ultimately close the gap between strategy and execution that so commonly nags innovation initiatives.  More on this coming soon so stay tuned! Unique Networking Opportunities  We know it can be challenging during OpenWorld to find time to productively connect and network with your industry peers, so we hosted an Agile PLM “Birds of a Feather” networking brunch for the second year in a row.  At a fine restaurant close to Moscone we hosted nine tables, each with only ten seats to encourage active conversation.  Furthermore, guests could select from a list of predetermined table topics sponsored by a specialized PLM partner to guarantee – even more so – that they were seated with like-minded company and optimizing their time at the conference.  Everyone enjoyed the opportunity to easily connect with other PLM users during OpenWorld in a more casual setting. What’s Next? Thank you again to all who joined us!  If you haven't yet, mark your calendar to join us for the next Oracle Agile PLM conference at the Value Chain Summit in San Francisco, February 4-6 in 2013!  We’ll have 40 sessions of PLM content in four tracks. Don’t miss it! You can sign up to be notified when official registration opens by visiting www.oracle.com/goto/vcs.

• ODI 11g - Cleaning control characters and User Functions

  - by David Allan

  In ODI user functions have a poor name really, they should be user expressions - a way of wrapping common expressions that you may wish to reuse many times - across many different technologies is an added bonus. To illustrate look at the problem of how to remove control characters from text. Users ask these types of questions over all technologies - Microsoft SQL Server, Oracle, DB2 and for many years - how do I clean a string, how do I tokenize a string and so on. After some searching around you will find a few ways of doing this, in Oracle there is a convenient way of using the TRANSLATE and REPLACE functions. So you can convert some text using the following SQL; replace( translate('This is my string'||chr(9)||' which has a control character', chr(3)||chr(4)||chr(5)||chr(9), chr(3) ), chr(3), '' ) If you had many columns to perform this kind of transformation on, in the Oracle database the natural solution you'd go to would be to code this as a PLSQL function since you don't want the code splattered everywhere. Someone tells you that there is another control character that needs added equals a maintenance headache. Coding it as a PLSQL function will incur a context switch between SQL and PLSQL which could prove costly. In ODI user functions let you capture this expression text and reference it many times across your mappings. This will protect the expression from being copy-pasted by developers and make maintenance much simpler - change the expression definition in one place. Firstly define a name and a syntax for the user function, I am calling it UF_STRIP_BAD_CHARACTERS and it has one parameter an input string;  We then can define an implementation for each technology we will use it, I will define Oracle's using the inputString parameter and the TRANSLATE and REPLACE functions with whatever control characters I want to replace; I can then use this inside mapping expressions in ODI, below I am cleaning the ENAME column - a fabricated example but you get the gist.  Note when I use the user function the function name remains in the text of the mapping, the actual expression is not substituted until I generate the scenario. If you generate the scenario and export the scenario you can have a peak at the code that is processed in the runtime - below you can see a snippet of my export scenario;  That's all for now, hopefully a useful snippet of info.

• Wireless Broadcom 4313 not working on Ubuntu 12.04

  - by user88568

  It seems a lot of people are having this problem, but none of the posted solutions have worked for me so far. My driver is installed and activated, I have tried removing and re-adding the network, and various other fixes. No networks were picked up on my first boot, the next day wireless worked fine, and since then it does not detect networks, and when I manually try to connect, it repeatedly asks for the password and does not connect. Here's my info: 03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) Subsystem: Dell Inspiron M5010 / XPS 8300 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at f0500000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [58] Vendor Specific Information: Len=78 Capabilities: [48] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [d0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [13c] Virtual Channel Capabilities: [160] Device Serial Number 00-00-a1-ff-ff-f3-70-f1 Capabilities: [16c] Power Budgeting Kernel driver in use: wl Kernel modules: wl, bcma, brcmsmac root@michelle-laptop:/home/michelle# ifconfig eth0 Link encap:Ethernet HWaddr 70:f1:a1:f3:ba:ab inet6 addr: fe80::72f1:a1ff:fef3:baab/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:29 TX packets:0 errors:30 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:17 eth1 Link encap:Ethernet HWaddr f0:4d:a2:53:83:7a UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:43 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:104 errors:0 dropped:0 overruns:0 frame:0 TX packets:104 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:8000 (8.0 KB) TX bytes:8000 (8.0 KB) root@michelle-laptop:/home/michelle# lsmod Module Size Used by dm_crypt 22528 0 snd_hda_codec_hdmi 31775 1 snd_hda_codec_realtek 174313 1 snd_hda_intel 32765 5 snd_hda_codec 109562 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel snd_hwdep 13276 1 snd_hda_codec snd_pcm 80845 4 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec snd_seq_midi 13132 0 snd_rawmidi 25424 1 snd_seq_midi snd_seq_midi_event 14475 1 snd_seq_midi snd_seq 51567 2 snd_seq_midi,snd_seq_midi_event parport_pc 32114 0 ppdev 12849 0 binfmt_misc 17292 1 lib80211_crypt_tkip 17275 0 bnep 17830 2 rfcomm 38139 0 snd_timer 28931 2 snd_pcm,snd_seq snd_seq_device 14172 3 snd_seq_midi,snd_rawmidi,snd_seq joydev 17393 0 wl 2646601 0 snd 62064 19 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 14635 1 snd btusb 17912 0 bluetooth 158438 11 bnep,rfcomm,btusb uvcvideo 67203 0 videodev 86588 1 uvcvideo snd_page_alloc 14108 2 snd_hda_intel,snd_pcm lib80211 14040 2 lib80211_crypt_tkip,wl intel_ips 17822 0 psmouse 72919 0 serio_raw 13027 0 mei 36570 0 dell_laptop 17767 0 dell_wmi 12601 0 dcdbas 14098 1 dell_laptop sparse_keymap 13658 1 dell_wmi mac_hid 13077 0 lp 17455 0 parport 40930 3 parport_pc,ppdev,lp usbhid 41906 0 hid 77367 1 usbhid wmi 18744 1 dell_wmi i915 414817 3 atl1c 36718 0 drm_kms_helper 45466 1 i915 drm 197692 4 i915,drm_kms_helper i2c_algo_bit 13199 1 i915 video 19068 1 i915 root@michelle-laptop:/home/michelle# iwlist scan lo Interface doesn't support scanning. eth1 Interface doesn't support scanning. eth0 No scan results root@michelle-laptop:/home/michelle# rfkill list 0: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: no 1: dell-bluetooth: Bluetooth Soft blocked: yes Hard blocked: no 3: brcmwl-0: Wireless LAN Soft blocked: no Hard blocked: no Obviously I don't know what I'm doing.

• Common SOA Problems by C2B2

  - by JuergenKress

  SOA stands for Service Oriented Architecture and has only really come together as a concrete approach in the last 15 years or so, although the concepts involved have been around for longer. Oracle SOA Suite is based around the Service Component Architecture (SCA) devised by the Open SOA collaboration of companies including Oracle and IBM. SCA, as used in SOA suite, is designed as a way to crystallise the concepts of SOA into a standard which ensures that SOA principles like the separation of application and business logic are maintained. Orchestration or Integration? A common thing to see with many people who are beginning to either build a new SOA based infrastructure, or move an old system to be service oriented, is confusion in the purpose of SOA technologies like BPEL and enterprise service buses. For a lot of problems, orchestration tools like BPEL or integration tools like an ESB will both do the job and achieve the right objectives; however it’s important to remember that, although a hammer can be used to drive a screw into wood, that doesn’t mean it’s the best way to do it. Service Integration is the act of connecting components together at a low level, which usually results in a single external endpoint for you to expose to your customers or other teams within your organisation – a simple product ordering system, for example, might integrate a stock checking service and a payment processing service. Process Orchestration, however, is generally a higher level approach whereby the (often externally exposed) service endpoints are brought together to track an end-to-end business process. This might include the earlier example of a product ordering service and couple it with a business rules service and human task to handle edge-cases. A good (but not exhaustive) rule-of-thumb is that integrations performed by an ESB will usually be real-time, whereas process orchestration in a SOA composite might comprise processes which take a certain amount of time to complete, or have to wait pending manual intervention. BPEL vs BPMN For some, with pre-existing SOA or business process projects, this decision is effectively already made. For those embarking on new projects it’s certainly an important consideration for those using Oracle SOA software since, due to the components included in SOA Suite and BPM Suite, the choice of which to buy is determined by what they offer. Oracle SOA suite has no BPMN engine, whereas BPM suite has both a BPMN and a BPEL engine. SOA suite has the ESB component “Mediator”, whereas BPM suite has none. Decisions must be made, therefore, on whether just one or both process modelling languages are to be used. The wrong decision could be costly further down the line.

• Should Exterrnal USB hard drive auto mount Ubuntu 12.04.01 LTS

  - by Chris Good

  I want to have external USB hard drives automatically mounted when plugged in. I have 2 drives exactly the same except for volume label. They both have the same UUID. I want to be easily able to swap them as I'm using them for backups and want to keep 1 at home for off site backup. I've set up the /etc/fstab so they should mount at different places based on their volume label: /etc/fstab : LABEL=Passport1 /media/Passport1 ntfs defaults,windows_names,locale=en_US.utf8 0 0 LABEL=Passport2 /media/Passport2 ntfs defaults,windows_names,locale=en_US.utf8 0 0 blkid shows : ... /dev/sdc1: LABEL="Passport2" UUID="4E1AEA7B1AEA6007" TYPE="ntfs" /dev/sdd1: LABEL="Passport1" UUID="4E1AEA7B1AEA6007" TYPE="ntfs" They both mount automatically during reboot but do not mount when just plugged in to a running system. I've read lots of stuff about this, much of it is old so I'm not sure if it applies. I've read some stuff that says the mounts should happen automatically when plugged in, and lots of other stuff that says you have to install other software to make this happen, although much of it just seems to set up the fstab. What's the real story? Here is /var/log/syslog when drive is plugged in: Dec 14 11:22:58 ausyvutims1 kernel: [66221.300196] usb 1-1: new high-speed USB device number 6 using ehci_hcd Dec 14 11:22:58 ausyvutims1 mtp-probe: checking bus 1, device 6: "/sys/devices/pci0000:00/0000:00:11.0/0000:02:03.0/usb1/1-1" Dec 14 11:22:58 ausyvutims1 mtp-probe: bus: 1, device: 6 was not an MTP device Dec 14 11:22:58 ausyvutims1 kernel: [66221.656020] scsi7 : usb-storage 1-1:1.0 Dec 14 11:22:59 ausyvutims1 kernel: [66222.661534] scsi 7:0:0:0: Direct-Access WD My Passport 0748 1016 PQ: 0 ANSI: 6 Dec 14 11:22:59 ausyvutims1 kernel: [66222.666466] scsi 7:0:0:1: Enclosure WD SES Device 1016 PQ: 0 ANSI: 6 Dec 14 11:22:59 ausyvutims1 kernel: [66222.667739] sd 7:0:0:0: Attached scsi generic sg3 type 0 Dec 14 11:22:59 ausyvutims1 kernel: [66222.667913] ses 7:0:0:1: Attached Enclosure device Dec 14 11:22:59 ausyvutims1 kernel: [66222.668047] ses 7:0:0:1: Attached scsi generic sg4 type 13 Dec 14 11:22:59 ausyvutims1 kernel: [66222.678473] sd 7:0:0:0: [sdc] 1953458176 512-byte logical blocks: (1.00 TB/931 GiB) Dec 14 11:22:59 ausyvutims1 kernel: [66222.687700] sd 7:0:0:0: [sdc] Write Protect is off Dec 14 11:22:59 ausyvutims1 kernel: [66222.687705] sd 7:0:0:0: [sdc] Mode Sense: 47 00 10 08 Dec 14 11:22:59 ausyvutims1 kernel: [66222.701076] sd 7:0:0:0: [sdc] No Caching mode page present Dec 14 11:22:59 ausyvutims1 kernel: [66222.701081] sd 7:0:0:0: [sdc] Assuming drive cache: write through Dec 14 11:22:59 ausyvutims1 kernel: [66222.738062] sd 7:0:0:0: [sdc] No Caching mode page present Dec 14 11:22:59 ausyvutims1 kernel: [66222.738068] sd 7:0:0:0: [sdc] Assuming drive cache: write through Dec 14 11:22:59 ausyvutims1 kernel: [66222.754558] sdc: sdc1 Dec 14 11:22:59 ausyvutims1 kernel: [66222.792006] sd 7:0:0:0: [sdc] No Caching mode page present Dec 14 11:22:59 ausyvutims1 kernel: [66222.792012] sd 7:0:0:0: [sdc] Assuming drive cache: write through Dec 14 11:22:59 ausyvutims1 kernel: [66222.792016] sd 7:0:0:0: [sdc] Attached SCSI disk Dec 14 11:22:59 ausyvutims1 ata_id[16971]: HDIO_GET_IDENTITY failed for '/dev/sdc': Invalid argument Thanks for any help offered
