• Big Data – Interacting with Hadoop – What is PIG? – What is PIG Latin? – Day 16 of 21

  - by Pinal Dave

  In yesterday’s blog post we learned the importance of the HIVE in Big Data Story. In this article we will understand what is PIG and PIG Latin in Big Data Story. Yahoo started working on Pig for their application deployment on Hadoop. The goal of Yahoo to manage their unstructured data. What is Pig and What is Pig Latin? Pig is a high level platform for creating MapReduce programs used with Hadoop and the language we use for this platform is called PIG Latin. The pig was designed to make Hadoop more user-friendly and approachable by power-users and nondevelopers. PIG is an interactive execution environment supporting Pig Latin language. The language Pig Latin has supported loading and processing of input data with series of transforming to produce desired results. PIG has two different execution environments 1) Local Mode – In this case all the scripts run on a single machine. 2) Hadoop – In this case all the scripts run on Hadoop Cluster. Pig Latin vs SQL Pig essentially creates set of map and reduce jobs under the hoods. Due to same users does not have to now write, compile and build solution for Big Data. The pig is very similar to SQL in many ways. The Ping Latin language provide an abstraction layer over the data. It focuses on the data and not the structure under the hood. Pig Latin is a very powerful language and it can do various operations like loading and storing data, streaming data, filtering data as well various data operations related to strings. The major difference between SQL and Pig Latin is that PIG is procedural and SQL is declarative. In simpler words, Pig Latin is very similar to SQ Lexecution plan and that makes it much easier for programmers to build various processes. Whereas SQL handles trees naturally, Pig Latin follows directed acyclic graph (DAG). DAGs is used to model several different kinds of structures in mathematics and computer science. DAG Tomorrow In tomorrow’s blog post we will discuss about very important components of the Big Data Ecosystem – Zookeeper.

• Microsoft Technical Computing

  - by Daniel Moth

  In the past I have described the team I belong to here at Microsoft (Parallel Computing Platform) in terms of contributing to Visual Studio and related products, e.g. .NET Framework. To be more precise, our team is part of the Technical Computing group, which is still part of the Developer Division. This was officially announced externally earlier this month in an exec email (from Bob Muglia, the president of STB, to which DevDiv belongs). Here is an extract: "… As we build the Technical Computing initiative, we will invest in three core areas: 1. Technical computing to the cloud: Microsoft will play a leading role in bringing technical computing power to scientists, engineers and analysts through the cloud. Existing high- performance computing users will benefit from the ability to augment their on-premises systems with cloud resources that enable ‘just-in-time’ processing. This platform will help ensure processing resources are available whenever they are needed—reliably, consistently and quickly. 2. Simplify parallel development: Today, computers are shipping with more processing power than ever, including multiple cores, but most modern software only uses a small amount of the available processing power. Parallel programs are extremely difficult to write, test and trouble shoot. However, a consistent model for parallel programming can help more developers unlock the tremendous power in today’s modern computers and enable a new generation of technical computing. We are delivering new tools to automate and simplify writing software through parallel processing from the desktop… to the cluster… to the cloud. 3. Develop powerful new technical computing tools and applications: We know scientists, engineers and analysts are pushing common tools (i.e., spreadsheets and databases) to the limits with complex, data-intensive models. They need easy access to more computing power and simplified tools to increase the speed of their work. We are building a platform to do this. Our development efforts will yield new, easy-to-use tools and applications that automate data acquisition, modeling, simulation, visualization, workflow and collaboration. This will allow them to spend more time on their work and less time wrestling with complicated technology. …" Our Parallel Computing Platform team is directly responsible for item #2, and we work very closely with the teams delivering items #1 and #3. At the same time as the exec email, our marketing team unveiled a website with interviews that I invite you to check out: Modeling the World. Comments about this post welcome at the original blog.

• Monogame/SharpDX - Shader parameters missing

  - by Layoric

  I am currently working on a simple game that I am building in Windows 8 using MonoGame (develop3d). I am using some shader code from a tutorial (made by Charles Humphrey) and having an issue populating a 'texture' parameter as it appears to be missing. Edit I have also tried 'Texture2D' and using it with a register(t0), still no luck I'm not well versed writing shaders, so this might be caused by a more obvious problem. I have debugged through MonoGame's Content processor to see how this shader is being parsed, all the non 'texture' parameters are there and look to be loading correctly. Edit This seems to go back to D3D compiler. Shader code below: #include "PPVertexShader.fxh" float2 lightScreenPosition; float4x4 matVP; float2 halfPixel; float SunSize; texture flare; sampler2D Scene: register(s0){ AddressU = Clamp; AddressV = Clamp; }; sampler Flare = sampler_state { Texture = (flare); AddressU = CLAMP; AddressV = CLAMP; }; float4 LightSourceMaskPS(float2 texCoord : TEXCOORD0 ) : COLOR0 { texCoord -= halfPixel; // Get the scene float4 col = 0; // Find the suns position in the world and map it to the screen space. float2 coord; float size = SunSize / 1; float2 center = lightScreenPosition; coord = .5 - (texCoord - center) / size * .5; col += (pow(tex2D(Flare,coord),2) * 1) * 2; return col * tex2D(Scene,texCoord); } technique LightSourceMask { pass p0 { VertexShader = compile vs_4_0 VertexShaderFunction(); PixelShader = compile ps_4_0 LightSourceMaskPS(); } } I've removed default values as they are currently not support in MonoGame and also changed ps and vs to v4 instead of 2. Could this be causing the issue? As I debug through 'DXConstantBufferData' constructor (from within the MonoGameContentProcessing project) I find that the 'flare' parameter does not exist. All others seem to be getting created fine. Any help would be appreciated. Update 1 I have discovered that SharpDX D3D compiler is what seems to be ignoring this parameter (perhaps by design?). The ConstantBufferDescription.VariableCount seems to be not counting the texture variable. Update 2 SharpDX function 'GetConstantBuffer(int index)' returns the parameters (minus textures) which is making is impossible to set values to these variables within the shader. Any one know if this is normal for DX11 / Shader Model 4.0? Or am I missing something else?

• What micro web-framework has the lowest overhead but includes templating

  - by Simon Martin

  I want to rewrite a simple small (10 page) website and besides a contact form it could be written in pure html. It is currently built with classic asp and Dreamweaver templates. The reason I'm not simply writing 10 html pages is that I want to keep the layout all in 1 place so would need either includes or a masterpage. I don't want to use Dreamweaver templates, or batch processing (like org-mode) because I want to be able to edit using notepad (or Visual Studio) because occasionally I might need to edit a file on the server (Go Daddy's IIS admin interface will let me edit text). I don't want to use ASP.NET MVC or WebForms (which I use in my day job) because I don't need all the overhead they bring with them when essentially I'm serving up 9 static files, 1 contact form and 1 list of clubs (that I aim to use jQuery to filter). The shared hosting package I have on Go Daddy seems to take a long time to spin up when serving aspx files. Currently the clubs page is driven from an MS SQL database that I try to keep up to date by manually checking the dojo locator on the main HQ pages and editing the entries myself, this is again way over the top. I aim to get a text file with the club details (probably in JSON or xml format) and use that as the source for the clubs page. There will need to be a bit of programming for this as the HQ site is unable to provide an extract / feed so something will have to scrape the site periodically to update my clubs persistence file. I'd like that to be automated - but I'm happy to have that triggered on a visit to the clubs page so I don't need to worry about scheduling a job. I would probably have a separate process that updates the persistence that has nothing to do with the rest of the site. Ideally I'd like to use Mercurial (or git) to publish, I know Bitbucket (and github) both serve static page sites so they wouldn't work in this scenario (dynamic pages and a contact form) but that's the model I'd like to use if there is such a thing. My requirements are: Simple templating system, 1 place to define header, footers, menu etc., that can be edited using just notepad. Very minimal / lightweight framework. I don't need a monster for 10 pages Must run either on IIS7 (shared Go Daddy Windows hosting) or other free host

• Pure Front end JavaScript with Web API versus MVC views with ajax

  - by eyeballpaul

  This was more a discussion for what peoples thoughts are these days on how to split a web application. I am used to creating an MVC application with all its views and controllers. I would normally create a full view and pass this back to the browser on a full page request, unless there were specific areas that I did not want to populate straight away and would then use DOM page load events to call the server to load other areas using AJAX. Also, when it came to partial page refreshing, I would call an MVC action method which would return the HTML fragment which I could then use to populate parts of the page. This would be for areas that I did not want to slow down initial page load, or areas that fitted better with AJAX calls. One example would be for table paging. If you want to move on to the next page, I would prefer it if an AJAX call got that info rather than using a full page refresh. But the AJAX call would still return an HTML fragment. My question is. Are my thoughts on this archaic because I come from a .net background rather than a pure front end background? An intelligent front end developer that I work with, prefers to do more or less nothing in the MVC views, and would rather do everything on the front end. Right down to web API calls populating the page. So that rather than calling an MVC action method, which returns HTML, he would prefer to return a standard object and use javascript to create all the elements of the page. The front end developer way means that any benefits that I normally get with MVC model validation, including client side validation, would be gone. It also means that any benefits that I get with creating the views, with strongly typed html templates etc would be gone. I believe this would mean I would need to write the same validation for front end and back end validation. The javascript would also need to have lots of methods for creating all the different parts of the DOM. For example, when adding a new row to a table, I would normally use the MVC partial view for creating the row, and then return this as part of the AJAX call, which then gets injected into the table. By using a pure front end way, the javascript would would take in an object (for, say, a product) for the row from the api call, and then create a row from that object. Creating each individual part of the table row. The website in question will have lots of different areas, from administration, forms, product searching etc. A website that I don't think requires to be architected in a single page application way. What are everyone's thoughts on this? I am interested to hear from front end devs and back end devs.

• Taking the training wheels off: Accelerating the Business with Oracle IAM by Brian Mozinski (Accenture)

  - by Greg Jensen

  Today, technical requirements for IAM are evolving rapidly, and the bar is continuously raised for high performance IAM solutions as organizations look to roll out high volume use cases on the back of legacy systems.  Existing solutions were often designed and architected to support offline transactions and manual processes, and the business owners today demand globally scalable infrastructure to support the growth their business cases are expected to deliver. To help IAM practitioners address these challenges and make their organizations and themselves more successful, this series we will outline the: • Taking the training wheels off: Accelerating the Business with Oracle IAM The explosive growth in expectations for IAM infrastructure, and the business cases they support to gain investment in new security programs. • "Necessity is the mother of invention": Technical solutions developed in the field Well proven tricks of the trade, used by IAM guru’s to maximize your solution while addressing the requirements of global organizations. • The Art & Science of Performance Tuning of Oracle IAM 11gR2 Real world examples of performance tuning with Oracle IAM • No Where to go but up: Extending the benefits of accelerated IAM Anything is possible, compelling new solutions organizations are unlocking with accelerated Oracle IAM Let’s get started … by talking about the changing dynamics driving these discussions. Big Companies are getting bigger everyday, and increasingly organizations operate across state lines, multiple times zones, and in many countries or continents at the same time.  No longer is midnight to 6am a safe time to take down the system for upgrades, to run recon’s and import or update user accounts and attributes.  Further IT organizations are operating as shared services with SLA’s similar to telephone carrier levels expected by their “clients”.  Workers are moved in and out of roles on a weekly, daily, or even hourly rate and IAM is expected to support those rapid changes.  End users registering for services during business hours in Singapore are expected their access to be green-lighted in custom apps hosted in Portugal within the hour.  Many of the expectations of asynchronous systems and batched updates are not adequate and the number and types of users is growing. When organizations acted more like independent teams at functional or geographic levels it was manageable to have processes that relied on a handful of people who knew how to make things work …. Knew how to get you access to the key systems to get your job done.  Today everyone is expected to do more with less, the finance administrator previously supporting their local Atlanta sales office might now be asked to help close the books for the Johannesburg team, and access certification process once completed monthly by Joan on the 3rd floor is now done by a shared pool of resources in Sao Paulo.   Fragmented processes that rely on institutional knowledge to get access to systems and get work done quickly break down in these scenarios.  Highly robust processes that have automated workflows for connected or disconnected systems give organizations the dynamic flexibility to share work across these lines and cut costs or increase productivity. As the IT industry computing paradigms continue to change with the passing of time, and as mature or proven approaches become clear, it is normal for organizations to adjust accordingly. Businesses must manage identity in an increasingly hybrid world in which legacy on-premises IAM infrastructures are extended or replaced to support more and more interconnected and interdependent services to a wider range of users. The old legacy IAM implementation models we had relied on to manage identities no longer apply. End users expect to self-request access to services from their tablet, get supervisor approval over mobile devices and email, and launch the application even if is hosted on the cloud, or run by a partner, vendor, or service provider. While user expectations are higher, they are also simpler … logging into custom desktop apps to request approvals, or going through email or paper based processes for certification is unacceptable.  Users expect security to operate within the paradigm of the application … i.e. feel like the application they are using. Citizen and customer facing applications have evolved from every where, with custom applications, 3rd party tools, and merging in from acquired entities or 3rd party OEM’s resold to expand your portfolio of services.  These all have their own user stores, authentication models, user lifecycles, session management, etc.  Often the designers/developers are no longer accessible and the documentation is limited.  Bringing together underlying directories to scale for growth, and improve user experience is critical for revenue … but also for operations. Job functions are more dynamic.... take the Olympics for example.  Endless organizations from corporations broadcasting, endorsing, or marketing through the event … to non-profit athletic foundations and public/government entities for athletes and public safety, all operate simultaneously on the world stage.  Each organization needs to spin up short-term teams, often dealing with proprietary information from hot ads to racing strategies or security plans.  IAM is expected to enable team’s to spin up, enable new applications, protect privacy, and secure critical infrastructure.  Then it needs to be disabled just as quickly as users go back to their previous responsibilities. On a more technical level … Optimized system directory; tuning guidelines and parameters are needed by businesses today. Business’s need to be making the right choices (virtual directories) and considerations via choosing the correct architectural patterns (virtual, direct, replicated, and tuning), challenge is that business need to assess and chose the correct architectural patters (centralized, virtualized, and distributed) Today's Business organizations have very complex heterogeneous enterprises that contain diverse and multifaceted information. With today's ever changing global landscape, the strategic end goal in challenging times for business is business agility. The business of identity management requires enterprise's to be more agile and more responsive than ever before. The continued proliferation of networking devices (PC, tablet, PDA's, notebooks, etc.) has caused the number of devices and users to be granted access to these devices to grow exponentially. Business needs to deploy an IAM system that can account for the demands for authentication and authorizations to these devices. Increased innovation is forcing business and organizations to centralize their identity management services. Access management needs to handle traditional web based access as well as handle new innovations around mobile, as well as address insufficient governance processes which can lead to rouge identity accounts, which can then become a source of vulnerabilities within a business’s identity platform. Risk based decisions are providing challenges to business, for an adaptive risk model to make proper access decisions via standard Web single sign on for internal and external customers,. Organizations have to move beyond simple login and passwords to address trusted relationship questions such as: Is this a trusted customer, client, or citizen? Is this a trusted employee, vendor, or partner? Is this a trusted device? Without a solid technological foundation, organizational performance, collaboration, constituent services, or any other organizational processes will languish. A Single server location presents not only network concerns for distributed user base, but identity challenges. The network risks are centered on latency of the long trip that the traffic has to take. Other risks are a performance around availability and if the single identity server is lost, all access is lost. As you can see, there are many reasons why performance tuning IAM will have a substantial impact on the success of your organization.  In our next installment in the series we roll up our sleeves and get into detailed tuning techniques used everyday by thought leaders in the field implementing Oracle Identity & Access Management Solutions.

• Odd Profiler Results with EF4

  - by AjarnMark

  I have been doing some testing of using the Microsoft Entity Framework 4 with stored procedures and ran across some really odd results in SQL Server Profiler. The application that is running which uses Entity Framework 4 is a simple Web Application written in C#, and the Entity Data Model is actually contained in a referenced class library of its own.  I’ll write more about my experiences with this later.  For now the question is, why does SQL Profiler think that the stored procedure is running in Master, and not in my application database? While analyzing the effects of using custom helper methods on my EDM classes to call the stored procedure, I decided to run Profiler while I stepped through the code so that I had a clear understanding of exactly when and what calls were made to the SQL Server.  I ran Profiler switching back and forth between the TSQL and TSQL_SP templates.  However, to reduce the amount of results rows I needed to wade through, I set a filter on DatabaseID to be equal to my application’s database.  Each time I ran this, the only thing that I saw was an Audit:Login to the database, but no procedure or T-SQL statements executed, yet I was definitely getting results back to my web page.  I tried other Profiler templates, still filtering on DatabaseID (tangent: I found, at least back in SQL 2000 Profiler, that filtering on DatabaseID was more reliable than filtering on DatabaseName.  Even though I’m now running SQL 2008, that habit sticks with me).  Still no results other than the Login.  Very weird! Finally, I decided to run Profiler with no filtering and discovered that that lines which represent my stored procedure and its T-SQL commands are all marked with DatabaseID = 1, which is Master.  Why in the world would that be?  My procedure is definitely in the application database, and not in Master, and there is nothing funny about the call to the procedure evident in Profiler (i.e. it is not called as MyAppDB.dbo.MyProcName, but rather just dbo.MyProcName).  There must be something funny with the way the Entity Framework is wrapping this call, and I don’t like it…I don’t like it one bit.  My primary PROD server contains 40+ databases on it, and when I need to profile something, I expect to be able to filter based on DatabaseID (for the record, I displayed DatabaseName in my results, too, and it also shows Master). I find the same pattern of everything except the Login showing up as being in Master when I run my version that uses standard LINQ to Entities instead of stored procedures, so that suggests it is not my code, but rather something funny with SQL Server 2008 Profiler or the Entity Framework. If you have any ideas about why this might be so, please comment below.

The previous posts were: JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue JMS Step 3 - Using the QueueReceive.java Sample Program to Read a Message from a JMS Queue JMS Step 4 - How to Create an 11g BPEL Process Which Writes a Message Based on an XML Schema to a JMS Queue Today we will create a BPEL process which will read (dequeue) the message from the JMS queue, which we enqueued in the last example. The JMS adapter will dequeue the full XML payload from the queue. 1. Recap and Prerequisites In the previous examples, we created a JMS Queue, a Connection Factory and a Connection Pool in the WebLogic Server Console. Then we designed and deployed a BPEL composite, which took a simple XML payload and enqueued it to the JMS queue. In this example, we will read that same message from the queue, using a JMS adapter and a BPEL process. As many of the configuration steps required to read from that queue were done in the previous samples, this one will concentrate on the new steps. A summary of the required objects is listed below. To find out how to create them please see the previous samples. They also include instructions on how to verify the objects are set up correctly. WebLogic Server Objects Object Name Type JNDI Name TestConnectionFactory Connection Factory jms/TestConnectionFactory TestJMSQueue JMS Queue jms/TestJMSQueue eis/wls/TestQueue Connection Pool eis/wls/TestQueue Schema XSD File The following XSD file is used for the message format. It was created in the previous example and will be copied to the new process. stringPayload.xsd <?xml version="1.0" encoding="windows-1252" ?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"                 xmlns="http://www.example.org"                 targetNamespace="http://www.example.org"                 elementFormDefault="qualified">   <xsd:element name="exampleElement" type="xsd:string">   </xsd:element> </xsd:schema> JMS Message After executing the previous samples, the following XML message should be in the JMS queue located at jms/TestJMSQueue: <?xml version="1.0" encoding="UTF-8" ?><exampleElement xmlns="http://www.example.org">Test Message</exampleElement> JDeveloper Connection You will need a valid Application Server Connection in JDeveloper pointing to the SOA server which the process will be deployed to. 2. Create a BPEL Composite with a JMS Adapter Partner Link In the previous example, we created a composite in JDeveloper called JmsAdapterWriteSchema. In this one, we will create a new composite called JmsAdapterReadSchema. There are probably many ways of incorporating a JMS adapter into a SOA composite for incoming messages. One way is design the process in such a way that the adapter polls for new messages and when it dequeues one, initiates a SOA or BPEL instance. This is possibly the most common use case. Other use cases include mid-flow adapters, which are activated from within the BPEL process. In this example we will use a polling adapter, because it is the most simple to set up and demonstrate. But it has one disadvantage as a demonstrative model. When a polling adapter is active, it will dequeue all messages as soon as they reach the queue. This makes it difficult to monitor messages we are writing to the queue, because they will disappear from the queue as soon as they have been enqueued. To work around this, we will shut down the composite after deploying it and restart it as required. (Another solution for this would be to pause the consumption for the queue and resume consumption again if needed. This can be done in the WLS console JMS-Modules -> queue -> Control -> Consumption -> Pause/Resume.) We will model the composite as a one-way incoming process. Usually, a BPEL process will do something useful with the message after receiving it, such as passing it to a database or file adapter, a human workflow or external web service. But we only want to demonstrate how to dequeue a JMS message using BPEL and a JMS adapter, so we won’t complicate the design with further activities. However, we do want to be able to verify that we have read the message correctly, so the BPEL process will include a small piece of embedded java code, which will print the message to standard output, so we can view it in the SOA server’s log file. Alternatively, you can view the instance in the Enterprise Manager and verify the message. The following steps are all executed in JDeveloper. Create the project in the same JDeveloper application used for the previous examples or create a new one. Create a SOA Project Create a new project and choose SOA Tier > SOA Project as its type. Name it JmsAdapterReadSchema. When prompted for the composite type, choose Empty Composite. Create a JMS Adapter Partner Link In the composite editor, drag a JMS adapter over from the Component Palette to the left-hand swim lane, under Exposed Services. This will start the JMS Adapter Configuration Wizard. Use the following entries: Service Name: JmsAdapterRead Oracle Enterprise Messaging Service (OEMS): Oracle WebLogic JMS AppServer Connection: Use an application server connection pointing to the WebLogic server on which the JMS queue and connection factory mentioned under Prerequisites above are located. Adapter Interface > Interface: Define from operation and schema (specified later) Operation Type: Consume Message Operation Name: Consume_message Consume Operation Parameters Destination Name: Press the Browse button, select Destination Type: Queues, then press Search. Wait for the list to populate, then select the entry for TestJMSQueue , which is the queue created in a previous example. JNDI Name: The JNDI name to use for the JMS connection. As in the previous example, this is probably the most common source of error. This is the JNDI name of the JMS adapter’s connection pool created in the WebLogic Server and which points to the connection factory. JDeveloper does not verify the value entered here. If you enter a wrong value, the JMS adapter won’t find the queue and you will get an error message at runtime, which is very difficult to trace. In our example, this is the value eis/wls/TestQueue . (See the earlier step on how to create a JMS Adapter Connection Pool in WebLogic Server for details.) Messages/Message SchemaURL: We will use the XSD file created during the previous example, in the JmsAdapterWriteSchema project to define the format for the incoming message payload and, at the same time, demonstrate how to import an existing XSD file into a JDeveloper project. Press the magnifying glass icon to search for schema files. In the Type Chooser, press the Import Schema File button. Select the magnifying glass next to URL to search for schema files. Navigate to the location of the JmsAdapterWriteSchema project > xsd and select the stringPayload.xsd file. Check the “Copy to Project” checkbox, press OK and confirm the following Localize Files popup. Now that the XSD file has been copied to the local project, it can be selected from the project’s schema files. Expand Project Schema Files > stringPayload.xsd and select exampleElement: string . Press Next and Finish, which will complete the JMS Adapter configuration.Save the project. Create a BPEL Component Drag a BPEL Process from the Component Palette (Service Components) to the Components section of the composite designer. Name it JmsAdapterReadSchema and select Template: Define Service Later and press OK. Wire the JMS Adapter to the BPEL Component Now wire the JMS adapter to the BPEL process, by dragging the arrow from the adapter to the BPEL process. A Transaction Properties popup will be displayed. Set the delivery mode to async.persist. This completes the steps at the composite level. 3 . Complete the BPEL Process Design Invoke the BPEL Flow via the JMS Adapter Open the BPEL component by double-clicking it in the design view of the composite.xml, or open it from the project navigator by selecting the JmsAdapterReadSchema.bpel file. This will display the BPEL process in the design view. You should see the JmsAdapterRead partner link in the left-hand swim lane. Drag a Receive activity onto the BPEL flow diagram, then drag a wire (left-hand yellow arrow) from it to the JMS adapter. This will open the Receive activity editor. Auto-generate the variable by pressing the green “+” button and check the “Create Instance” checkbox. This will result in a BPEL instance being created when a new JMS message is received. At this point it would actually be OK to compile and deploy the composite and it would pick up any messages from the JMS queue. In fact, you can do that to test it, if you like. But it is very rudimentary and would not be doing anything useful with the message. Also, you could only verify the actual message payload by looking at the instance’s flow in the Enterprise Manager. There are various other possibilities; we could pass the message to another web service, write it to a file using a file adapter or to a database via a database adapter etc. But these will all introduce unnecessary complications to our sample. So, to keep it simple, we will add a small piece of Java code to the BPEL process which will write the payload to standard output. This will be written to the server’s log file, which will be easy to monitor. Add a Java Embedding Activity First get the full name of the process’s input variable, as this will be needed for the Java code. Go to the Structure pane and expand Variables > Process > Variables. Then expand the input variable, for example, "Receive1_Consume_Message_InputVariable > body > ns2:exampleElement”, and note variable’s name and path, if they are different from this one. Drag a Java Embedding activity from the Component Palette (Oracle Extensions) to the BPEL flow, after the Receive activity, then open it to edit. Delete the example code and replace it with the following, replacing the variable parts with those in your sample, if necessary.: System.out.println("JmsAdapterReadSchema process picked up a message"); oracle.xml.parser.v2.XMLElement inputPayload =    (oracle.xml.parser.v2.XMLElement)getVariableData(                           "Receive1_Consume_Message_InputVariable",                           "body",                           "/ns2:exampleElement");   String inputString = inputPayload.getFirstChild().getNodeValue(); System.out.println("Input String is " + inputPayload.getFirstChild().getNodeValue()); Tip. If you are not sure of the exact syntax of the input variable, create an Assign activity in the BPEL process and copy the variable to another, temporary one. Then check the syntax created by the BPEL designer. This completes the BPEL process design in JDeveloper. Save, compile and deploy the process to the SOA server. 3. Test the Composite Shut Down the JmsAdapterReadSchema Composite After deploying the JmsAdapterReadSchema composite to the SOA server it is automatically activated. If there are already any messages in the queue, the adapter will begin polling them. To ease the testing process, we will deactivate the process first Log in to the Enterprise Manager (Fusion Middleware Control) and navigate to SOA > soa-infra (soa_server1) > default (or wherever you deployed your composite to) and click on JmsAdapterReadSchema [1.0] . Press the Shut Down button to disable the composite and confirm the following popup. Monitor Messages in the JMS Queue In a separate browser window, log in to the WebLogic Server Console and navigate to Services > Messaging > JMS Modules > TestJMSModule > TestJMSQueue > Monitoring. This is the location of the JMS queue we created in an earlier sample (see the prerequisites section of this sample). Check whether there are any messages already in the queue. If so, you can dequeue them using the QueueReceive Java program created in an earlier sample. This will ensure that the queue is empty and doesn’t contain any messages in the wrong format, which would cause the JmsAdapterReadSchema to fail. Send a Test Message In the Enterprise Manager, navigate to the JmsAdapterWriteSchema created earlier, press Test and send a test message, for example “Message from JmsAdapterWriteSchema”. Confirm that the message was written correctly to the queue by verifying it via the queue monitor in the WLS Console. Monitor the SOA Server’s Output A program deployed on the SOA server will write its standard output to the terminal window in which the server was started, unless this has been redirected to somewhere else, for example to a file. If it has not been redirected, go to the terminal session in which the server was started, otherwise open and monitor the file to which it was redirected. Re-Enable the JmsAdapterReadSchema Composite In the Enterprise Manager, navigate to the JmsAdapterReadSchema composite again and press Start Up to re-enable it. This should cause the JMS adapter to dequeue the test message and the following output should be written to the server’s standard output: JmsAdapterReadSchema process picked up a message. Input String is Message from JmsAdapterWriteSchema Note that you can also monitor the payload received by the process, by navigating to the the JmsAdapterReadSchema’s Instances tab in the Enterprise Manager. Then select the latest instance and view the flow of the BPEL component. The Receive activity will contain and display the dequeued message too. 4 . Troubleshooting This sample demonstrates how to dequeue an XML JMS message using a BPEL process and no additional functionality. For example, it doesn’t contain any error handling. Therefore, any errors in the payload will result in exceptions being written to the log file or standard output. If you get any errors related to the payload, such as Message handle error ... ORABPEL-09500 ... XPath expression failed to execute. An error occurs while processing the XPath expression; the expression is /ns2:exampleElement. ... etc. check that the variable used in the Java embedding part of the process was entered correctly. Possibly follow the tip mentioned in previous section. If this doesn’t help, you can delete the Java embedding part and simply verify the message via the flow diagram in the Enterprise Manager. Or use a different method, such as writing it to a file via a file adapter. This concludes this example. In the next post, we will begin with an AQ JMS example, which uses JMS to write to an Advanced Queue stored in the database.

• How To Fix YouTube Re-Buffering On Full Screen Issue

  - by Gopinath

  YouTube has an annoying bug – videos starts re-buffering when we switch to full screen mode from normal mode. On a high speed broadband connection the re-buffering issue may not be annoying much but on a slow broadband connection it annoys hell out of us. When users reported this problem to YouTube, the engineers at YouTube dubbed it as a feature rather than bug!. That is sick and this behaviour shows that they started ignoring the users and their problem. Anyways we got solutions to get around this annoying issue. Root Cause Of The Issue The root cause of the bug is YouTube’s resolution switching mechanism.When the video is loaded in normal model it is buffered and played at 360p, but when the full screen mode is activated YouTube player switches to 480p and starts re-buffering the video. How To Fix The Issue on Google Chrome Browser Fixing this issue on Google Chrome is very simple. All we need to do is to install this Greasemonkey script and it fixes everything for you. How To Fix The Issue on Firefox Browser Fixing this issue on Firefox browser involves an extra step when compared to Chrome browser. To fix the issue Step 1: Install Greasemonkey Addon for Firefox Step 2: Install this script from userscripts.org Done. Firefox will handle the full screen switching smoothly. How To Fix The Issue on Internet Explorer Hufff!! Internet Explorer users are poor users not because they are dumb but because they are using stone age browser. No offense, IE is a pathetic browser and there is no support for Greasemonkey scripts. Anyway lets look at the solution for fixing YouTube issue on IE. To fix the YouTube bug you need to follow the official solution provided by Google and it’s not a friendly one. Step 1: Login to your YouTube account and select the option “I have a slow connection. Never play higher-quality video“. Step 2 – Repeat Always: Make sure that you are always logged into your YouTube account as YouTube need to know your settings before switching the resolution. (Now you know why I called IE as a poor browser).

• How to become a solid python web developer [closed]

  - by Estarius

  Possible Duplicate: How do I learn Python from zero to web development? I have started Python recently with the goal to become a solid developer to make a web application eventually. However, as time goes by I am wondering if I am being optimal about how I will achieve my goal. I would compare it to a game for example, to be better you must spend time playing and trying new things... However, if you just log in and sit in the lobby chatting you are most likely not progressing. So far, this is my plan (feel free to comment or judge it): Review basic programmation concepts Start coding slowly in Python Once comfortable in Python, learn about web development in Python Learn about those things we heard about: SQLAlchemy, MVC, TDD, Git, Agile (Group project) To achieve these things, I started the Learn python the hard way exercises, which I am doing at the rate of 5 per days. I also started to read Think Python at the same time and planning to move on with Dive into python. As far as my research goes, these documentations along with Python documentation is usually what is the most recommended to learn Python. I consider this to get my point 1 and 2 done. While learning Python is really great, my goal remains to do quality web development. I know there are books about Django etc. however I would like to become comfortable with any Python web development. This means without Framework and with Framework... Any framework, then be able to choose the one which best fits our needs. For this I would like to know if some people have suggestions. Should I just get a book on Django and it should apply to everything ? What would be the best method to go from Python to Web Python and not end up creating crappy code which would turn into nightmares for other programmers ? Then finally, those "things we hear about". While I understand what they all do basically, I am fairly sure that like everything, there are good and wrong ways of making use of them. Should I go through at least a whole book on each before starting to use them or keep it at their respective online documentation ? Are there some kind of documentation which links their use to Python ? Also, from looking at Django and Pyramid they seems to use something else than MVC, while the Django model looks similar, the Pyramid one seems to cut a whole part of it... Is learning MVC still worth it ? Sorry for the wall of text, Thanks in advance !

• Sony VAIO with Insyde H2O EFI bios will not boot into GRUB EFI

  - by Rohan Dhruva

  I bought a new Sony Vaio S series laptop. It uses Insyde H2O BIOS EFI, and trying to install Linux on it is driving me crazy. root@kubuntu:~# parted /dev/sda print Model: ATA Hitachi HTS72756 (scsi) Disk /dev/sda: 640GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 274MB 273MB fat32 EFI system partition hidden 2 274MB 20.8GB 20.6GB ntfs Basic data partition hidden, diag 3 20.8GB 21.1GB 273MB fat32 EFI system partition boot 4 21.1GB 21.3GB 134MB Microsoft reserved partition msftres 5 21.3GB 342GB 320GB ntfs Basic data partition 6 342GB 358GB 16.1GB ext4 Basic data partition 7 358GB 374GB 16.1GB ntfs Basic data partition 8 374GB 640GB 266GB ntfs Basic data partition What is surprising is that there are 2 EFI system partitions on the disk. The sda2 partition is a 20gb recovery partition which loads windows with a basic recovery interface. This is accessible by pressing the "ASSIST" button as opposed to the normal power button. I presume that the sda1 EFI System Partition (ESP) loads into this recovery. The sda3 ESP has more fleshed out entries for Microsoft Windows, which actually goes into Windows 7 (as confirmed by bcdedit.exe on Windows). Ubuntu is installed on sda6, and while installation I chose sda3 as my boot partition. The installer correctly created a sda3/EFI/ubuntu/grubx64.efi application. The real problem: for the life of me, I can't set it to be the default! I tried creating a sda3/startup.nsh which called grubx64.efi, but it didn't help -- on rebooting, the system still boots into windows. I tried using efibootmgr, and that shows as it it worked: root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager root@kubuntu:~# efibootmgr --create --gpt --disk /dev/sda --part 3 --write-signature --label "GRUB2" --loader "\\EFI\\ubuntu\\grubx64.efi" BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 However, on rebooting, as you guessed, the machine rebooted directly back into Windows. The only things I can think of are: The sda1 partition is somehow being used Overwrite /EFI/Boot/bootx64.efi and /EFI/Microsoft/Boot/bootmgfw.efi with grubx64.efi [but this seems really radical]. Can anyone please help me out? Thanks -- any help is greatly appreciated, as this issue is driving me crazy!

• Scrum and Team Consolidation

  I’m still working my way through one of the more painful team consolidations of my career.  One thing that’s made it hard was my assumption that the use of Agile methods and Scrum would make everything easy.  Take three teams, make all work visible, track it, and presto: An efficient, functioning software development team. What I’ve come to realize is that the primary benefit of Scrum is that Scrum brings teams closer to their customers.  Frequent meetings, short iterations, and phased deployments are all meant to keep the customer in the loop.  It’s true that as teams become proficient with Scrum they tend to become more efficient.  But I don’t think it’s true that Scrum automatically helps people work together. Instead, Scrum can point out when teams aren’t good at working together.   And it really illustrates when teams, especially teams in sustaining mode, are reacting to their customers instead of innovating with them.  At the moment we’ve inherited a huge backlog of tools, processes, and personalities.  It’s up to us to sort them all out.  Unfortunately, after 7 &frac12; months we’re still sorting. What I’d recommend for any blended team is to look at your current product lifecycles and work on a single lifecycle for all work.  If you can’t objectively come up with one process, that’s a good indication that the new team might not be a good fit for being a single unit (which happens all the time in bigger companies).  Go ahead & self-organize into sub-teams.  Then repeat the process. If you can come up with a single process, tackle each piece and standardize all of them.  Do this as soon as possible, as it can be uncomfortable.  Standardize your requirements gathering and tracking, your exploration and technical analysis, your project planning, development standards, validation and sustaining processes.  Standardize all of it.  Make this your top priority, get it out of the way, and get back to work. Lastly, managers of blended teams should realize what I’m suggesting is a disruptive process.  But you’ve just reorganized the team is already disrupted.   Don’t pull the bandage off slowly and force the team through a prolonged transition phase, lowering their productivity over the long term.  You can role model leadership to your team and drive a true consolidation.  Destroy roadblocks, reassure those on your team who are afraid of change, and push forward to create something efficient and beautiful.  Then use Scrum to reengage your customers in a way that they’ll love.

• One email user keeps disconnecting from our exchange server

  - by Funky Si

  I have one user who keeps reporting that Outlook keeps disconnecting from our email server. All other users are fine. Our email server is running Exchange 2010 and the client is running Outlook 2003. The disconnection only lasts a moment. I have checked for logs on the client and Exchange server and can not see any reason for the disconnect, On the Client I get EventId 26 telling me Outlook has disconnected and reconnected but no reason why. Can anyone give me some suggestions of things to try and track down where the problem could be? --Update-- I have found the following log file C:\Program Files\Microsoft\Exchange Server\V14\Logging\RPC Client Access which suggests that it is a problem with RPC sessions.

• Simple tips to design a Customer Journey Map

  - by Isabel F. Peñuelas

  “A model can abstract to a level that is comprehensible to humans, without getting lost in details.” -The Unified Modeling Language Reference Manual. Inception using Post-it, StoryBoards, Lego or Mindmaping Techniques The first step in a Customer Experience project is to describe customer interactions creating a customer journey map. Modeling is never easy, so to succeed on this effort, it is very convenient that your CX´s team have some “abstract thinking” skills. Besides is very helpful to consult a Business Service Design offered by an Interactive Agency to lead your inception process. Initially, you may start by a free discussion using post-it cards; storyboards; even lego or any other brainstorming technique you like. This will help you to get your mind into the path followed by the customer to purchase your product or to consume any business service you actually offer to your customers, or plan to offer in the near future. (from www.servicedesigntools.org) Colorful Mind Maps are very useful to document and share meeting ideas. Some Mind Maps software providers as ThinkBuzzan provide trial versions, and you will find more mindmapping options on this post by Mashable. Finally to produce a quick one, I do recommend Wise, an entirely online mindmaping service. On my view the best results in terms of communication will always come for an artistic hand-made drawing. Customer Experience Mind Map Example Making your first Customer Journey Map To add some more formalization to your thoughts, there is a wide offering for designing Customer Journey Maps. A Customer Map can be represented as an oriented graph in which another follows each step. The one below is the most simple Customer Journey you can draw. Nothing more than a couple of pictures, numbers and lines to design the customer steps sequence in the purchase process. Very simple Customer Journey for Social Mobile Shopping There are a lot of Customer Journey templates much more sophisticated available  in the Web using a variety of styles, as per example this one with a focus on underlining emotional experience, or this other worksheet template. Representing different interaction devices on the vertical axis, and touchpoints / requirements and existing gaps horizontally  is today´s most common format for Customer Journeys. From Customer Journey Maps to CX Technology Adoption Plans Once you have your map ready, you can start to identify the IT infrastructure requirements for your CXProject. By analyzing customer problems and improvement opportunities with maps, you will then identify the technology gaps and the new investment requirements in your IT infrastructure. Deeping step by step from the more abstract to the more concrete is the best guarantee to take the right IT investment decisions.  ¡Remember to keep your initial customer journey safe on your pocket in every one of your CX´s project meetings- that´s you map to success!

• Responding to Invites

  - by Daniel Moth

  Following up from my post about Sending Outlook Invites here is a shorter one on how to respond. Whatever your choice (ACCEPT, TENTATIVE, DECLINE), if the sender has not unchecked the "Request Response" option, then send your response. Always send your response. Even if you think the sender made a mistake in keeping it on, send your response. Seriously, not responding is plain rude. If you knew about the meeting, and you are happy investing your time in it, and the time and location work for you, and there is an implicit/explicit agenda, then ACCEPT and send it. If one or more of those things don't work for you then you have a few options. Send a DECLINE explaining why. Reply with email to ask for further details or for a change to be made. If you don’t receive a response to your email, send a DECLINE when you've waited enough. Send a TENTATIVE if you haven't made up your mind yet. Hint: if they really require you there, they'll respond asking "why tentative" and you have a discussion about it. When you deem appropriate, instead of the options above, you can also use the counter propose feature of Outlook but IMO that feature has questionable interaction model and UI (on both sender and recipient) so many people get confused by it. BTW, two of my outlook rules are relevant to invites. The first one auto-marks as read the ACCEPT responses if there is no comment in the body of the accept (I check later who has accepted and who hasn't via the "Tracking" button of the invite). I don’t have a rule for the DECLINE and TENTATIVE cause typically I follow up with folks that send those.   The second rule ensures that all Invites go to a specific folder. That is the first folder I see when I triage email. It is also the only folder which I have configured to show a count of all items inside it, rather than the unread count - when sending a response to an invite the item disappears from the folder and hence it is empty and not nagging me. Comments about this post by Daniel Moth welcome at the original blog.

• MVC data binding

  - by user441521

  I'm using MVC but I've read that MVVM is sort of about data binding and having pure markup in your views that data bind back to the backend via the data-* attributes. I've looked at knockout but it looks pretty low level and I feel like I can make a library that does this and is much easier to use where basically you only need to call 1 javascript function that will data bind your entire page because of the data-* attributes you assign to html elements. The benefits of this (that I see) is that your view is 100% decoupled from your back-end so that a given view never has to be changed if your back-end changes (ie for asp.net people no more razor in your view that makes your view specific to MS). My question would be, I know there is knockout out there but are there any others that provide this data binding functionality for MVC type applications? I don't want to recreate something that may already exist but I want to make something "better" and easier to use than knockout. To give an example of what I mean here is all the code one would need to get data binding in my library. This isn't final but just showing the idea that all you have to do is call 1 javascript function and set some data-* attribute values and everything ties together. Is this worth seeing through? <script> $(function () { // this is all you have to call to make databinding for POST or GET to work DataBind(); }); </script> <form id="addCustomer" data-bind="Customer" data-controller="Home" data-action="CreateCustomer"> Name: <input type="text" data-bind="Name" data-bind-type="text" /> Birthday: <input type="text" data-bind="Birthday" data-bind-type="text" /> Address: <input type="text" data-bind="Address" data-bind-type="text" /> <input type="submit" value="Save" id="btnSave" /> </form> ================================================= // controller action [HttpPost] public string CreateCustomer(Customer customer) { if(customer.Name == "Rick") return "success"; return "failure"; } // model public class Customer { public string Name { get; set; } public DateTime Birthday { get; set; } public string Address { get; set; } }

• Easy Scaling in XAML (WPF)

  - by Robert May

  Ran into a problem that needed solving that was kind of fun.  I’m not a XAML guru, and I’m sure there are better solutions, but I thought I’d share mine. The problem was this:  Our designer had, appropriately, designed the system for a 1920 x 1080 screen resolution.  This is for a full screen, touch screen device (think Kiosk), which has that resolution, but we also wanted to demo the device on a tablet (currently using the AWESOME Samsung tablet given out at Microsoft Build).  When you’d run it on that tablet, things were ugly because it was at a lower resolution than the target device. Enter scaling.  I did some research and found out that I probably just need to monkey with the LayoutTransform of some grid somewhere.  This project is using MVVM and has a navigation container that we built that lives on a single root view.  User controls are then loaded into that view as navigation occurs. In the parent grid of the root view, I added the following XAML: <Grid.LayoutTransform> <ScaleTransform ScaleX="{Binding ScaleWidth}" ScaleY="{Binding ScaleHeight}" /> </Grid.LayoutTransform> And then in the root View Model, I added the following code: /// <summary> /// The required design width /// </summary> private const double RequiredWidth = 1920; /// <summary> /// The required design height /// </summary> private const double RequiredHeight = 1080; /// <summary>Gets the ActualHeight</summary> public double ActualHeight { get { return this.View.ActualHeight; } } /// <summary>Gets the ActualWidth</summary> public double ActualWidth { get { return this.View.ActualWidth; } } /// <summary> /// Gets the scale for the height. /// </summary> public double ScaleHeight { get { return this.ActualHeight / RequiredHeight; } } /// <summary> /// Gets the scale for the width. /// </summary> public double ScaleWidth { get { return this.ActualWidth / RequiredWidth; } } Note that View.ActualWidth and View.ActualHeight are just pointing directly at FrameworkElement.ActualWidth and FrameworkElement.ActualHeight. That’s it.  Just calculate the ratio and bind the scale transform to it. Hopefully you’ll find this useful. Technorati Tags: WPF,XAML
