• GLSL Atmospheric Scattering Issue

  - by mtf1200

  I am attempting to use Sean O'Neil's shaders to accomplish atmospheric scattering. For now I am just using SkyFromSpace and GroundFromSpace. The atmosphere works fine but the planet itself is just a giant dark sphere with a white blotch that follows the camera. I think the problem might rest in the "v3Attenuation" variable as when this is removed the sphere is show (albeit without scattering). Here is the vertex shader. Thanks for the time! uniform mat4 g_WorldViewProjectionMatrix; uniform mat4 g_WorldMatrix; uniform vec3 m_v3CameraPos; // The camera's current position uniform vec3 m_v3LightPos; // The direction vector to the light source uniform vec3 m_v3InvWavelength; // 1 / pow(wavelength, 4) for the red, green, and blue channels uniform float m_fCameraHeight; // The camera's current height uniform float m_fCameraHeight2; // fCameraHeight^2 uniform float m_fOuterRadius; // The outer (atmosphere) radius uniform float m_fOuterRadius2; // fOuterRadius^2 uniform float m_fInnerRadius; // The inner (planetary) radius uniform float m_fInnerRadius2; // fInnerRadius^2 uniform float m_fKrESun; // Kr * ESun uniform float m_fKmESun; // Km * ESun uniform float m_fKr4PI; // Kr * 4 * PI uniform float m_fKm4PI; // Km * 4 * PI uniform float m_fScale; // 1 / (fOuterRadius - fInnerRadius) uniform float m_fScaleDepth; // The scale depth (i.e. the altitude at which the atmosphere's average density is found) uniform float m_fScaleOverScaleDepth; // fScale / fScaleDepth attribute vec4 inPosition; vec3 v3ELightPos = vec3(g_WorldMatrix * vec4(m_v3LightPos, 1.0)); vec3 v3ECameraPos= vec3(g_WorldMatrix * vec4(m_v3CameraPos, 1.0)); const int nSamples = 2; const float fSamples = 2.0; varying vec4 color; float scale(float fCos) { float x = 1.0 - fCos; return m_fScaleDepth * exp(-0.00287 + x*(0.459 + x*(3.83 + x*(-6.80 + x*5.25)))); } void main(void) { gl_Position = g_WorldViewProjectionMatrix * inPosition; // Get the ray from the camera to the vertex and its length (which is the far point of the ray passing through the atmosphere) vec3 v3Pos = vec3(g_WorldMatrix * inPosition); vec3 v3Ray = v3Pos - v3ECameraPos; float fFar = length(v3Ray); v3Ray /= fFar; // Calculate the closest intersection of the ray with the outer atmosphere (which is the near point of the ray passing through the atmosphere) float B = 2.0 * dot(m_v3CameraPos, v3Ray); float C = m_fCameraHeight2 - m_fOuterRadius2; float fDet = max(0.0, B*B - 4.0 * C); float fNear = 0.5 * (-B - sqrt(fDet)); // Calculate the ray's starting position, then calculate its scattering offset vec3 v3Start = m_v3CameraPos + v3Ray * fNear; fFar -= fNear; float fDepth = exp((m_fInnerRadius - m_fOuterRadius) / m_fScaleDepth); float fCameraAngle = dot(-v3Ray, v3Pos) / fFar; float fLightAngle = dot(v3ELightPos, v3Pos) / fFar; float fCameraScale = scale(fCameraAngle); float fLightScale = scale(fLightAngle); float fCameraOffset = fDepth*fCameraScale; float fTemp = (fLightScale + fCameraScale); // Initialize the scattering loop variables float fSampleLength = fFar / fSamples; float fScaledLength = fSampleLength * m_fScale; vec3 v3SampleRay = v3Ray * fSampleLength; vec3 v3SamplePoint = v3Start + v3SampleRay * 0.5; // Now loop through the sample rays vec3 v3FrontColor = vec3(0.0, 0.0, 0.0); vec3 v3Attenuate; for(int i=0; i<nSamples; i++) { float fHeight = length(v3SamplePoint); float fDepth = exp(m_fScaleOverScaleDepth * (m_fInnerRadius - fHeight)); float fScatter = fDepth*fTemp - fCameraOffset; v3Attenuate = exp(-fScatter * (m_v3InvWavelength * m_fKr4PI + m_fKm4PI)); v3FrontColor += v3Attenuate * (fDepth * fScaledLength); v3SamplePoint += v3SampleRay; } vec3 first = v3FrontColor * (m_v3InvWavelength * m_fKrESun + m_fKmESun); vec3 secondary = v3Attenuate; color = vec4((first + vec3(0.25,0.25,0.25) * secondary), 1.0); // ^^ that color is passed to the frag shader and is used as the gl_FragColor } Here is also an image of the problem image

• 7u10: JavaFX packaging tools update

  - by igor

  Last weeks were very busy here in Oracle. JavaOne 2012 is next week. Come to see us there! Meanwhile i'd like to quickly update you on recent developments in the area of packaging tools. This is an area of ongoing development for the team, and we are  continuing to refine and improve both the tools and the process. Thanks to everyone who shared experiences and suggestions with us. We are listening and fixed many of reported issues. Please keep them coming as comments on the blog or (even better) file issues directly to the JIRA. In this post i'll focus on several new packaging features added in JDK 7 update 10: Self-Contained Applications: Select Java Runtime to bundle Self-Contained Applications: Create Package without Java Runtime Self-Contained Applications: Package non-JavaFX application Option to disable proxy setup in the JavaFX launcher Ability to specify codebase for WebStart application Option to update existing jar file Self-Contained Applications: Specify application icon Self-Contained Applications: Pass parameters on the command line All these features and number of other important bug fixes are available in the developer preview builds of JDK 7 update 10 (build 8 or later). Please give them a try and share your feedback! Self-Contained Applications: Select Java Runtime to bundle Packager tools in 7u6 assume current JDK (based on java.home property) is the source for embedded runtime. This is useful simplification for many scenarios but there are cases where ability to specify what to embed explicitly is handy. For example IDE may be using fixed JDK to build the project and this is not the version you want to bundle into your application. To make it more flexible we now allow to specify location of base JDK explicitly. It is optional and if you do not specify it then current JDK will be used (i.e. this change is fully backward compatible). New 'basedir' attribute was added to <fx:platform> tag. Its value is location of JDK to be used. It is ok to point to either JRE inside the JDK or JDK top level folder. However, it must be JDK and not JRE as we need other JDK tools for proper packaging and it must be recent version of JDK that is bundled with JavaFX (i.e. Java 7 update 6 or later). Here are examples (<fx:platform> is part of <fx:deploy> task): <fx:platform basedir="${java.home}"/> <fx:platform basedir="c:\tools\jdk7"/> Hint: this feature enables you to use packaging tools from JDK 7 update 10 (and benefit from bug fixes and other features described below) to create application package with bundled FCS version of JRE 7 update 6. Self-Contained Applications: Create Package without Java Runtime This may sound a bit puzzling at first glance. Package without embedded Java Runtime is not really self-contained and obviously will not help with: Deployment on fresh systems. JRE need to be installed separately (and this step will require admin permissions). Possible compatibility issues due to updates of system runtime. However, these packages are much much smaller in size. If download size matters and you are confident that user have recommended system JRE installed then this may be good option to consider if you want to improve user experience for install and launch. Technically, this is implemented as an extension of previous feature. Pass empty string as value for 'basedir' attribute and this will be treated as request to not bundle Java runtime, e.g. <fx:platform basedir=""/> Self-Contained Applications: Package non-JavaFX application One of popular questions people ask about self-contained applications - can i package my Java application as self-contained application? Absolutely. This is true even for tools shipped with JDK 7 update 6. Simply follow steps for creating package for Swing application with integrated JavaFX content and they will work even if your application does not use JavaFX. What's wrong with it? Well, there are few caveats: bundle size is larger because JavaFX is bundled whilst it is not really needed main application jar needs to be packaged to comply to JavaFX packaging requirements(and this may be not trivial to achieve in your existing build scripts) javafx application launcher may not work well with startup logic of your application (for example launcher will initialize networking stack and this may void custom networking settings in your application code) In JDK 7 update 6 <fx:deploy> was updated to accept arbitrary executable jar as an input. Self-contained application package will be created preserving input jar as-is, i.e. no JavaFX launcher will be embedded. This does not help with first point above but resolves other two. More formally following assertions must be true for packaging to succeed: application can be launched as "java -jar YourApp.jar" from the command line  mainClass attribute of <fx:application> refers to application main class <fx:resources> lists all resources needed for the application To give you an example lets assume we need to create a bundle for application consisting of 3 jars:     dist/javamain.jar     dist/lib/somelib.jar    dist/morelibs/anotherlib.jar where javamain.jar has manifest with      Main-Class: app.Main     Class-Path: lib/somelib.jar morelibs/anotherlib.jar Here is sample ant code to package it: <target name="package-bundle"> <taskdef resource="com/sun/javafx/tools/ant/antlib.xml" uri="javafx:com.sun.javafx.tools.ant" classpath="${javafx.tools.ant.jar}"/> <fx:deploy nativeBundles="all" width="100" height="100" outdir="native-packages/" outfile="MyJavaApp"> <info title="Sample project" vendor="Me" description="Test built from Java executable jar"/> <fx:application id="myapp" version="1.0" mainClass="app.Main" name="MyJavaApp"/> <fx:resources> <fx:fileset dir="dist"> <include name="javamain.jar"/> <include name="lib/somelib.jar"/> <include name="morelibs/anotherlib.jar"/> </fx:fileset> </fx:resources> </fx:deploy> </target> Option to disable proxy setup in the JavaFX launcher Since JavaFX 2.2 (part of JDK 7u6) properly packaged JavaFX applications  have proxy settings initialized according to Java Runtime configuration settings. This is handy for most of the application accessing network with one exception. If your application explicitly sets networking properties (e.g. socksProxyHost) then they must be set before networking stack is initialized. Proxy detection will initialize networking stack and therefore your custom settings will be ignored. One way to disable proxy setup by the embedded JavaFX launcher is to pass "-Djavafx.autoproxy.disable=true" on the command line. This is good for troubleshooting (proxy detection may cause significant startup time increases if network is misconfigured) but not really user friendly. Now proxy setup will be disabled if manifest of main application jar has "JavaFX-Feature-Proxy" entry with value "None". Here is simple example of adding this entry using <fx:jar> task: <fx:jar destfile="dist/sampleapp.jar"> <fx:application refid="myapp"/> <fx:resources refid="myresources"/> <fileset dir="build/classes"/> <manifest> <attribute name="JavaFX-Feature-Proxy" value="None"/> </manifest> </fx:jar> Ability to specify codebase for WebStart application JavaFX applications do not need to specify codebase (i.e. absolute location where application code will be deployed) for most of real world deployment scenarios. This is convenient as application does not need to be modified when it is moved from development to deployment environment. However, some developers want to ensure copies of their application JNLP file will redirect to master location. This is where codebase is needed. To avoid need to edit JNLP file manually <fx:deploy> task now accepts optional codebase attribute. If attribute is not specified packager will generate same no-codebase files as before. If codebase value is explicitly specified then generated JNLP files (including JNLP content embedded into web page) will use it.  Here is an example: <fx:deploy width="600" height="400" outdir="Samples" codebase="http://localhost/codebaseTest" outfile="TestApp"> .... </fx:deploy> Option to update existing jar file JavaFX packaging procedures are optimized for new application that can use ant or command line javafxpackager utility. This may lead to some redundant steps when you add it to your existing build process. One typical situation is that you might already have a build procedure that produces executable jar file with custom manifest. To properly package it as JavaFX executable jar you would need to unpack it and then use javafxpackager or <fx:jar> to create jar again (and you need to make sure you pass all important details from your custom manifest). We added option to pass jar file as an input to javafxpackager and <fx:jar>. This simplifies integration of JavaFX packaging tools into existing build  process as postprocessing step. By the way, we are looking for ways to simplify this further. Please share your suggestions! On the technical side this works as follows. Both <fx:jar> and javafxpackager will attempt to update existing jar file if this is the only input file. Update process will add JavaFX launcher classes and update the jar manifest with JavaFX attributes. Your custom attributes will be preserved. Update could be performed in place or result may be saved to a different file. Main-Class and Class-Path elements (if present) of manifest of input jar file will be used for JavaFX application  unless they are explicitly overriden in the packaging command you use. E.g. attribute mainClass of <fx:application> (or -appclass in the javafxpackager case) overrides existing Main-Class in the jar manifest. Note that class specified in the Main-Class attribute could either extend JavaFX Application or provide static main() method. Here are examples of updating jar file using javafxpackager: Create new JavaFX executable jar as a copy of given jar file javafxpackager -createjar -srcdir dist -srcfiles fish_proto.jar -outdir dist -outfile fish.jar  Update existing jar file to be JavaFX executable jar and use test.Fish as main application class javafxpackager -createjar -srcdir dist -appclass test.Fish -srcfiles fish.jar -outdir dist -outfile fish.jar  And here is example of using <fx:jar> to create new JavaFX executable jar from the existing fish_proto.jar: <fx:jar destfile="dist/fish.jar"> <fileset dir="dist"> <include name="fish_proto.jar"/> </fileset> </fx:jar> Self-Contained Applications: Specify application icon The only way to specify application icon for self-contained application using tools in JDK 7 update 6 is to use drop-in resources. Now this bug is resolved and you can also specify icon using <fx:icon> tag. Here is an example: <fx:deploy ...> <fx:info> <fx:icon href="default.png"/> </fx:info> ... </fx:deploy> Few things to keep in mind: Only default kind of icon is applicable to self-contained applications (as of now) Icon should follow platform specific rules for sizes and image format (e.g. .ico on Windows and .icns on Mac) Self-Contained Applications: Pass parameters on the command line JavaFX applications support two types of application parameters: named and unnamed (see the API for Application.Parameters). Static named parameters can be added to the application package using <fx:param> and unnamed parameters can be added using <fx:argument>. They are applicable to all execution modes including standalone applications. It is also possible to pass parameters to a JavaFX application from a Web page that hosts it, using <fx:htmlParam>.  Prior to JavaFX 2.2, this was only supported for embedded applications. Starting from JavaFX 2.2, <fx:htmlParam> is applicable to Web Start applications also. See JavaFX deployment guide for more details on this. However, there was no way to pass dynamic parameters to the self-contained application. This has been improved and now native launchers will  delegate parameters from command line to the application code. I.e. to pass parameter to the application you simply need to run it as "myapp.exe somevalue" and then use getParameters().getUnnamed().get(0) to get "somevalue".

• Login screen restarts while entering password

  - by Shane L

  I am having a problem that only occurred after installing the fglrx proprietary driver through the additional drivers app. The exact same issue is described in this question, however it's closed. Must login twice before entering Unity; first login screen has graphical anomalies When I boot up my computer, once I get to lightdm login screen I will start typing my password, and upon the entering of two of my password characters "n2" the screen will start displaying some corruption in the very top edge of the screen, then after I hit the number 2, lightdm seems to crash and it will restart and everything is fine, I can login from that point. So the issue is, every time I reboot, I have to login once, allow lightdm to crash and restart, then login as normal. The issue did not occur prior to installing fglrx, and has happened through several reinstalls.

• As a code monkey, how to discuss programming with a guy who almost has a doctorate in computer science

  - by Peter Turner

  A friend of my wife's is coming over for dinner tonight and he is a lot smarter than me. What do we have in common, well... A Bachelor's in Computer Science, and that should be enough of a conversation starter. But he's nearly completed his doctoral studies and is light years ahead of me in his particular area, which I find fascinating but don't have any legit reason to care about (except for maybe a better way through heavy traffic - he's a combinatorics guy specializing in that I think) and I got married and had some kids and am a professional programmer for medical records software. We've got a lot in common, but there's a point where neither of us care or understand each other - although I really want to learn from him and I'm not certain he'd even want to talk about his work. So for all you doctors or code monkeys, what's a good conversation starter!

• python, cluster computing, design help [closed]

  - by j dawg

  I would like to create my own parallel computing server. Can you please point me to some resources I can use to help me develop my server. Sorry, like I said I need help getting started. Yes, I am limited to python, I cannot use C. I am using a bunch of workstations and I want to use all the cpus in those machines. So what I am looking for is blog posts, books, articles that can help me develop my own client/server tools to send code from the client to the servers and spawn python processes based on the number of cpus. I know how to do the subprocessing/multiprocessing part of the program, I do not know how to create the server that will take the client's requests. I also need to figure out what is the best way to handle sending file data, like netcdf files or other spatial data. Any suggestions very welcome.

• Oracle Data Integrator 11.1.1.5 Complex Files as Sources and Targets

  - by Alex Kotopoulis

  Overview ODI 11.1.1.5 adds the new Complex File technology for use with file sources and targets. The goal is to read or write file structures that are too complex to be parsed using the existing ODI File technology. This includes: Different record types in one list that use different parsing rules Hierarchical lists, for example customers with nested orders Parsing instructions in the file data, such as delimiter types, field lengths, type identifiers Complex headers such as multiple header lines or parseable information in header Skipping of lines  Conditional or choice fields Similar to the ODI File and XML File technologies, the complex file parsing is done through a JDBC driver that exposes the flat file as relational table structures. Complex files are mapped to one or more table structures, as opposed to the (simple) file technology, which always has a one-to-one relationship between file and table. The resulting set of tables follows the same concept as the ODI XML driver, table rows have additional PK-FK relationships to express hierarchy as well as order values to maintain the file order in the resulting table.   The parsing instruction format used for complex files is the nXSD (native XSD) format that is already in use with Oracle BPEL. This format extends the XML Schema standard by adding additional parsing instructions to each element. Using nXSD parsing technology, the native file is converted into an internal XML format. It is important to understand that the XML is streamed to improve performance; there is no size limitation of the native file based on memory size, the XML data is never fully materialized.  The internal XML is then converted to relational schema using the same mapping rules as the ODI XML driver. How to Create an nXSD file Complex file models depend on the nXSD schema for the given file. This nXSD file has to be created using a text editor or the Native Format Builder Wizard that is part of Oracle BPEL. BPEL is included in the ODI Suite, but not in standalone ODI Enterprise Edition. The nXSD format extends the standard XSD format through nxsd attributes. NXSD is a valid XML Schema, since the XSD standard allows extra attributes with their own namespaces. The following is a sample NXSD schema: <?xml version="1.0"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:nxsd="http://xmlns.oracle.com/pcbpel/nxsd" elementFormDefault="qualified" xmlns:tns="http://xmlns.oracle.com/pcbpel/demoSchema/csv" targetNamespace="http://xmlns.oracle.com/pcbpel/demoSchema/csv" attributeFormDefault="unqualified" nxsd:encoding="US-ASCII" nxsd:stream="chars" nxsd:version="NXSD"> <xsd:element name="Root">         <xsd:complexType><xsd:sequence>       <xsd:element name="Header">                 <xsd:complexType><xsd:sequence>                         <xsd:element name="Branch" type="xsd:string" nxsd:style="terminated" nxsd:terminatedBy=","/>                         <xsd:element name="ListDate" type="xsd:string" nxsd:style="terminated" nxsd:terminatedBy="${eol}"/>                         </xsd:sequence></xsd:complexType>                         </xsd:element>                 </xsd:sequence></xsd:complexType>         <xsd:element name="Customer" maxOccurs="unbounded">                 <xsd:complexType><xsd:sequence>                 <xsd:element name="Name" type="xsd:string" nxsd:style="terminated" nxsd:terminatedBy=","/>                         <xsd:element name="Street" type="xsd:string" nxsd:style="terminated" nxsd:terminatedBy="," />                         <xsd:element name="City" type="xsd:string" nxsd:style="terminated" nxsd:terminatedBy="${eol}" />                         </xsd:sequence></xsd:complexType>                         </xsd:element>                 </xsd:sequence></xsd:complexType> </xsd:element> </xsd:schema> The nXSD schema annotates elements to describe their position and delimiters within the flat text file. The schema above uses almost exclusively the nxsd:terminatedBy instruction to look for the next terminator chars. There are various constructs in nXSD to parse fixed length fields, look ahead in the document for string occurences, perform conditional logic, use variables to remember state, and many more. nXSD files can either be written manually using an XML Schema Editor or created using the Native Format Builder Wizard. Both Native Format Builder Wizard as well as the nXSD language are described in the Application Server Adapter Users Guide. The way to start the Native Format Builder in BPEL is to create a new File Adapter; in step 8 of the Adapter Configuration Wizard a new Schema for Native Format can be created:   The Native Format Builder guides through a number of steps to generate the nXSD based on a sample native file. If the format is complex, it is often a good idea to “approximate” it with a similar simple format and then add the complex components manually.  The resulting *.xsd file can be copied and used as the format for ODI, other BPEL constructs such as the file adapter definition are not relevant for ODI. Using this technique it is also possible to parse the same file format in SOA Suite and ODI, for example using SOA for small real-time messages, and ODI for large batches. This nXSD schema in this example describes a file with a header row containing data and 3 string fields per row delimited by commas, for example: Redwood City Downtown Branch, 06/01/2011 Ebeneezer Scrooge, Sandy Lane, Atherton Tiny Tim, Winton Terrace, Menlo Park The ODI Complex File JDBC driver exposes the file structure through a set of relational tables with PK-FK relationships. The tables for this example are: Table ROOT (1 row): ROOTPK Primary Key for root element SNPSFILENAME Name of the file SNPSFILEPATH Path of the file SNPSLOADDATE Date of load Table HEADER (1 row): ROOTFK Foreign Key to ROOT record ROWORDER Order of row in native document BRANCH Data BRANCHORDER Order of Branch within row LISTDATE Data LISTDATEORDER Order of ListDate within row Table ADDRESS (2 rows): ROOTFK Foreign Key to ROOT record ROWORDER Order of row in native document NAME Data NAMEORDER Oder of Name within row STREET Data STREETORDER Order of Street within row CITY Data CITYORDER Order of City within row Every table has PK and/or FK fields to reflect the document hierarchy through relationships. In this example this is trivial since the HEADER and all CUSTOMER records point back to the PK of ROOT. Deeper nested documents require this to identify parent elements. All tables also have a ROWORDER field to define the order of rows, as well as order fields for each column, in case the order of columns varies in the original document and needs to be maintained. If order is not relevant, these fields can be ignored. How to Create an Complex File Data Server in ODI After creating the nXSD file and a test data file, and storing it on the local file system accessible to ODI, you can go to the ODI Topology Navigator to create a Data Server and Physical Schema under the Complex File technology. This technology follows the conventions of other ODI technologies and is very similar to the XML technology. The parsing settings such as the source native file, the nXSD schema file, the root element, as well as the external database can be set in the JDBC URL: The use of an external database defined by dbprops is optional, but is strongly recommended for production use. Ideally, the staging database should be used for this. Also, when using a complex file exclusively for read purposes, it is recommended to use the ro=true property to ensure the file is not unnecessarily synchronized back from the database when the connection is closed. A data file is always required to be present  at the filename path during design-time. Without this file, operations like testing the connection, reading the model data, or reverse engineering the model will fail.  All properties of the Complex File JDBC Driver are documented in the Oracle Fusion Middleware Connectivity and Knowledge Modules Guide for Oracle Data Integrator in Appendix C: Oracle Data Integrator Driver for Complex Files Reference. David Allan has created a great viewlet Complex File Processing - 0 to 60 which shows the creation of a Complex File data server as well as a model based on this server. How to Create Models based on an Complex File Schema Once physical schema and logical schema have been created, the Complex File can be used to create a Model as if it were based on a database. When reverse-engineering the Model, data stores(tables) for each XSD element of complex type will be created. Use of complex files as sources is straightforward; when using them as targets it has to be made sure that all dependent tables have matching PK-FK pairs; the same applies to the XML driver as well. Debugging and Error Handling There are different ways to test an nXSD file. The Native Format Builder Wizard can be used even if the nXSD wasn’t created in it; it will show issues related to the schema and/or test data. In ODI, the nXSD  will be parsed and run against the existing test XML file when testing a connection in the Dataserver. If either the nXSD has an error or the data is non-compliant to the schema, an error will be displayed. Sample error message: Error while reading native data. [Line=1, Col=5] Not enough data available in the input, when trying to read data of length "19" for "element with name D1" from the specified position, using "style" as "fixedLength" and "length" as "". Ensure that there is enough data from the specified position in the input. Complex File FAQ Is the size of the native file limited by available memory? No, since the native data is streamed through the driver, only the available space in the staging database limits the size of the data. There are limits on individual field sizes, though; a single large object field needs to fit in memory. Should I always use the complex file driver instead of the file driver in ODI now? No, use the file technology for all simple file parsing tasks, for example any fixed-length or delimited files that just have one row format and can be mapped into a simple table. Because of its narrow assumptions the ODI file driver is easy to configure within ODI and can stream file data without writing it into a database. The complex file driver should be used whenever the use case cannot be handled through the file driver. Are we generating XML out of flat files before we write it into a database? We don’t materialize any XML as part of parsing a flat file, either in memory or on disk. The data produced by the XML parser is streamed in Java objects that just use XSD-derived nXSD schema as its type system. We use the nXSD schema because is the standard for describing complex flat file metadata in Oracle Fusion Middleware, and enables users to share schemas across products. Is the nXSD file interchangeable with SOA Suite? Yes, ODI can use the same nXSD files as SOA Suite, allowing mixed use cases with the same data format. Can I start the Native Format Builder from the ODI Studio? No, the Native Format Builder has to be started from a JDeveloper with BPEL instance. You can get BPEL as part of the SOA Suite bundle. Users without SOA Suite can manually develop nXSD files using XSD editors. When is the database data written back to the native file? Data is synchronized using the SYNCHRONIZE and CREATE FILE commands, and when the JDBC connection is closed. It is recommended to set the ro or read_only property to true when a file is exclusively used for reading so that no unnecessary write-backs occur. Is the nXSD metadata part of the ODI Master or Work Repository? No, the data server definition in the master repository only contains the JDBC URL with file paths; the nXSD files have to be accessible on the file systems where the JDBC driver is executed during production, either by copying or by using a network file system. Where can I find sample nXSD files? The Application Server Adapter Users Guide contains nXSD samples for various different use cases.

• How do you create a .XNB Font file for use with CocosSharp?

  - by Chris Pietschmann

  I know the .XNB file format is an XNA thing and that CocosSharp inherits this from its MonoGame roots. However there doesn't seem to be any information on how to create your own .XNB fonts to use with CocosSharp. I've tried searching but can find any information. Could someone explain it here or point me to a tutorial on how to create .XNB font file for use with CocosSharp? A site to download already compiled .XNB Fonts would also be acceptable. Update: Another thing that makes this tricky is that I guess XNA Game Studio could be used, but it's not compatible with Windows 8.1; which is what I currently use for my dev machine...

• Why does my domain not show up in Google anymore?

  - by Earlz

  So I have had a website since about 2006. It's http://earlz.biz.tm . Recently I've noticed that no results will show up for it in google. I do have a secondary domain(that I plan on getting rid of) pointing to it but I don't understand why google would suddenly not show my site. I believe it was showing up a few months ago and my website is hardly ever down, like one or two days I believe has been the most it's been down in a row in this time period. Is there something wrong with my DNS or other configuration that would make google not index me? For reference I've tried: earlz.biz.tm site:earlz.biz.tm and the heading from my site "Earlz.biz.tm -- The reasoning is bacon" A few show up with the therusticstone.com domain(the one I plan to point somewhere else) but none show up directly linking to earlz.biz.tm.

• SQL Saturday 43 in Redmond

  - by AjarnMark

  I attended my first SQLSaturday a couple of days ago, SQLSaturday #43 in Redmond (at Microsoft).  I got there really early, primarily because I forgot how fast I can get there from my home when nobody else is on the road.  On a weekday in rush hour traffic, that would have taken two hours to get there.  I gave myself 90 minutes, and actually got there in about 45.  Crazy! I made the mistake of going to the main Microsoft campus, but that’s not where the event was being held.  Instead it was in a big Microsoft conference center on the other side of the highway.  Fortunately, I had the address with me and quickly realized my mistake.  When I got back on track, I noticed that there were bright yellow signs out on the street corner that looked like they said they were for SOL Saturday, which actually was appropriate since it was the sunniest day around here in a long time. Since I was there so early, the registration was just getting setup, so I found Greg Larsen who was coordinating things and offered to help.  He put me to work with a group of people organizing the pre-printed raffle tickets and stuffing swag bags. I had never been to a SQLSaturday before this one, so I wasn’t exactly sure what to expect even though I have read about a few on some blogs.  It makes sense that each one will be a little bit different since they are almost completely volunteer driven, and the whole concept is still in its early stages.  I have been to the PASS Summit for the last several years, and was hoping for a smaller version of that.  Now, it’s not really fair to compare one free day of training run entirely by volunteers with a multi-day, $1,000+ event put on under the direction of a professional event management company.  But there are some parallels. At this SQLSaturday, there was no opening general session, just coffee and pastries in the common area / expo hallway and straight into the first group of sessions.  I don’t know if that was because there was no single room large enough to hold everyone, or for other reasons.  This worked out okay, but the organization guy in me would have preferred to have even a 15 minute welcome message from the organizers with a little overview of the day.  Even something as simple as, “Thanks to persons X, Y, and Z for helping put this together…Sessions will start in 20 minutes and are all in rooms down this hallway…the bathrooms are on the other side of the conference center…lunch today is pizza and we would like to thank sponsor Q for providing it.”  It doesn’t need to be much, certainly not a full-blown Keynote like at the PASS Summit, but something to use as a rallying point to pull everyone together and get the day off to an official start would be nice.  Again, there may have been logistical reasons why that was not feasible here.  I’m just putting out my thoughts for other SQLSaturday coordinators to consider. The event overall was great.  I believe that there were over 300 in attendance, and everything seemed to run smoothly.  At least from an attendee’s point of view where there was plenty of muffins in the morning and pizza in the afternoon, with plenty of pop to drink.  And hey, if you’ve got the food and drink covered, a lot of other stuff could go wrong and people will be very forgiving.  But as I said, everything appeared to run pretty smoothly, at least until Buck Woody showed up in his Oracle shirt.  Other than that, the volunteers did a great job! I was a little surprised by how few people in my own backyard that I know.  It makes sense if you really think about it, given how many companies must be using SQL Server around here.  I guess I just got spoiled coming into the PASS Summit with a few contacts that I already knew would be there.  Perhaps I have been spending too much time with too few people at the Summits and I need to step out and meet more folks.  Of course, it also is different since the Summit is the big national event and a number of the folks I know are spread out across the country, so the Summit is the only time we’re all in the same place at the same time.  I did make a few new contacts at SQLSaturday, and bumped into a couple of people that I knew (and a couple others that I only knew from Twitter, and didn’t even realize that they were here in the area). Other than the sheer entertainment value of Buck Woody’s session, the one that was probably the greatest value for me was a quick introduction to PowerShell.  I have not done anything with it yet, but I think it will be a good tool to use to implement my plans for automated database recovery testing.  I saw just enough at the session to take away some of the intimidation factor, and I am getting ready to jump in and see what I can put together in the next few weeks.  And that right there made the investment worthwhile.  So I encourage you, if you have the opportunity to go to a SQLSaturday event near you, go for it!

• IBM DB2 and the “'DbProviderFactories' section can only appear once per config” error

  - by Davide Mauri

  IBM doesn’t like MS. That’s a fact. And that’s why you can get your machine.config file (!!!) corrupted if you try to install IBM DB2 data providers on your server machine. If at some point, after having installed IBM DB2 data providers your SSIS packages or SSAS cubes or SSRS Reports starts to complain that 'DbProviderFactories' section can only appear once per config you may want to check into you machine.config, located in the %runtime install path%\Config http://msdn.microsoft.com/en-us/library/ms229697%28v=vs.71%29.aspx Almost surely you’ll find a IBM DB2 Provider into an additional DbProviderFactories section all alone. Poor guy. Remove the double DBProviderFactories entry, and merge everything inside only one section DBProviderFactories and after that everything will start to work again.

• OWB 11gR2: Migration and Upgrade Paths from Previous Versions

  - by antonio romero

  Over the next several months, we expect widespread adoption of OWB 11gR2, both for its new features and because it is the only release of Warehouse Builder certified for use with database 11gR2. Customers seeking to move existing environments to OWB 11gR2 should review the new whitepaper, OWB 11.2: Upgrade and Migration Paths. This whitepaper covers the following topics: The difference between upgrade and migration, and how to choose between them An outline of how to perform each process When and where intermediate upgrade steps are required Tips for upgrading an existing environment to 11gR2 without having to regenerate and redeploy code to your production environment. Moving up from 10gR2 and 11gR1 is generally straightforward. For customers still using OWB 9 or 10.1, it is generally possible to move an entire environment forward complete with design and runtime audit metadata, but the upgrade process can be complex and may require intermediate processing using OWB 10.2 or OWB 11.1. Moving a design by itself is much simpler, though it requires regeneration and redeployment. Relevant details are provided in the whitepaper, so if you are planning an upgrade at some point soon, definitely start there.

I installed pgAdmin III from synaptic and also tried direct download from postgreSQL site using software installer. Regardlesss, I can get only get pgAdmin III for postgresql 9.1. When I run pgAdmin III and point to my server I get an error message telling me that the database is 9.2 and my pgAdmin III is for 9.1, isn't compatible with 9.2. I can access the server itself fine OK from the Ubuntu box - I have Python programs that hit the database with no problems - but I need pgAdmin III for 9.2 running under Ununtu Linux 12.10. Is it available? Where do I get it?

• Why lock-free data structures just aren't lock-free enough

  - by Alex.Davies

  Today's post will explore why the current ways to communicate between threads don't scale, and show you a possible way to build scalable parallel programming on top of shared memory. The problem with shared memory Soon, we will have dozens, hundreds and then millions of cores in our computers. It's inevitable, because individual cores just can't get much faster. At some point, that's going to mean that we have to rethink our architecture entirely, as millions of cores can't all access a shared memory space efficiently. But millions of cores are still a long way off, and in the meantime we'll see machines with dozens of cores, struggling with shared memory. Alex's tip: The best way for an application to make use of that increasing parallel power is to use a concurrency model like actors, that deals with synchronisation issues for you. Then, the maintainer of the actors framework can find the most efficient way to coordinate access to shared memory to allow your actors to pass messages to each other efficiently. At the moment, NAct uses the .NET thread pool and a few locks to marshal messages. It works well on dual and quad core machines, but it won't scale to more cores. Every time we use a lock, our core performs an atomic memory operation (eg. CAS) on a cell of memory representing the lock, so it's sure that no other core can possibly have that lock. This is very fast when the lock isn't contended, but we need to notify all the other cores, in case they held the cell of memory in a cache. As the number of cores increases, the total cost of a lock increases linearly. A lot of work has been done on "lock-free" data structures, which avoid locks by using atomic memory operations directly. These give fairly dramatic performance improvements, particularly on systems with a few (2 to 4) cores. The .NET 4 concurrent collections in System.Collections.Concurrent are mostly lock-free. However, lock-free data structures still don't scale indefinitely, because any use of an atomic memory operation still involves every core in the system. A sync-free data structure Some concurrent data structures are possible to write in a completely synchronization-free way, without using any atomic memory operations. One useful example is a single producer, single consumer (SPSC) queue. It's easy to write a sync-free fixed size SPSC queue using a circular buffer*. Slightly trickier is a queue that grows as needed. You can use a linked list to represent the queue, but if you leave the nodes to be garbage collected once you're done with them, the GC will need to involve all the cores in collecting the finished nodes. Instead, I've implemented a proof of concept inspired by this intel article which reuses the nodes by putting them in a second queue to send back to the producer. * In all these cases, you need to use memory barriers correctly, but these are local to a core, so don't have the same scalability problems as atomic memory operations. Performance tests I tried benchmarking my SPSC queue against the .NET ConcurrentQueue, and against a standard Queue protected by locks. In some ways, this isn't a fair comparison, because both of these support multiple producers and multiple consumers, but I'll come to that later. I started on my dual-core laptop, running a simple test that had one thread producing 64 bit integers, and another consuming them, to measure the pure overhead of the queue. So, nothing very interesting here. Both concurrent collections perform better than the lock-based one as expected, but there's not a lot to choose between the ConcurrentQueue and my SPSC queue. I was a little disappointed, but then, the .NET Framework team spent a lot longer optimising it than I did. So I dug out a more powerful machine that Red Gate's DBA tools team had been using for testing. It is a 6 core Intel i7 machine with hyperthreading, adding up to 12 logical cores. Now the results get more interesting. As I increased the number of producer-consumer pairs to 6 (to saturate all 12 logical cores), the locking approach was slow, and got even slower, as you'd expect. What I didn't expect to be so clear was the drop-off in performance of the lock-free ConcurrentQueue. I could see the machine only using about 20% of available CPU cycles when it should have been saturated. My interpretation is that as all the cores used atomic memory operations to safely access the queue, they ended up spending most of the time notifying each other about cache lines that need invalidating. The sync-free approach scaled perfectly, despite still working via shared memory, which after all, should still be a bottleneck. I can't quite believe that the results are so clear, so if you can think of any other effects that might cause them, please comment! Obviously, this benchmark isn't realistic because we're only measuring the overhead of the queue. Any real workload, even on a machine with 12 cores, would dwarf the overhead, and there'd be no point worrying about this effect. But would that be true on a machine with 100 cores? Still to be solved. The trouble is, you can't build many concurrent algorithms using only an SPSC queue to communicate. In particular, I can't see a way to build something as general purpose as actors on top of just SPSC queues. Fundamentally, an actor needs to be able to receive messages from multiple other actors, which seems to need an MPSC queue. I've been thinking about ways to build a sync-free MPSC queue out of multiple SPSC queues and some kind of sign-up mechanism. Hopefully I'll have something to tell you about soon, but leave a comment if you have any ideas.

• shader coding: calculate screen coordinates of fragment

  - by Jay

  Good morning, I'm new to shader coding and trying to implement some visual effects code in shaders using billboards. (Yes, I couldn't have picked anything harder to start with, but I'm lucky that way) Setup: I have rendered the full screen z depth to an array of floats in a previous pass. In the fragment shader I need the scene depth where the rendered fragment is displayed (to see if it's occluded). I can use tex2d() to get the depth value if I have the screen coordinates of the point being rendered in the fragment shader. Question: In the fragment shader how do you calculate the screen coordinates of the pixel (in the range 0-1.0)? Is the position passed to the fragment shader a pixel offset? If so, I guess it would be: float2( position.x / screen-width, position.y / screen-height ) Thanks for any help/

• Arithmetic Coding Questions

  - by Xophmeister

  I have been reading up on arithmetic coding and, while I understand how it works, all the guides and instructions I've read start with something like: Set up your intervals based upon the frequency of symbols in your data; i.e., more likely symbols get proportionally larger intervals. My main query is, once I have encoded my data, presumably I also need to include this statistical model with the encoding, otherwise the compressed data can't be decoded. Is that correct? I don't see this mentioned anywhere -- the most I've seen is that you need to include the number of iterations (i.e., encoded symbols) -- but unless I'm missing something, this also seems necessary to me. If this is true, that will obviously add an overhead to the final output. At what point does this outweigh the benefits of compression (e.g., say if I'm trying to compress just a few thousand bits)? Will the choice of symbol size also make a significant difference (e.g., if I'm looking at 2-bit words, rather than full octets/whatever)?

• Billboarding + aligning with velocity direction

  - by roxlu

  I'm working on a particle system where I'm orientating the billboard using the inverted orientation matrix of my camera. This works quite well and my quad are rotated correctly towards the camera. But, now I want to to rotate the quads in such a way that they point towards the direction they are going to. In 2D this can be done by normalizing the velocity vector and using that vector for a rotation around the Z-axis (where vel.x = cos(a) and vel.y = sin(a)). But how does this work in 3D? Thanks roxlu

• What Will Happen to Real Estate Leases when Operating Leases are Gone?

  - by Theresa Hickman

  Many people are concerned about what will happen to real estate leases when FASB and IASB abolish operating leases. They plan to unveil the proposed standards on treating leases this summer as part of the convergence project but no "finalized ruling" is expected for at least a year because it will need to get formal consensus from many players, such as the SEC, American Association of Investors, Congress, the Big Four, American Associate of Realtors, the international equivalents of these, etc. If your accounting is a bit rusty, an Operating Lease is where you lease equipment or some asset for a shorter period than the actual (expected) life of the asset and then give the asset back while it still has some useful life in it. (Think leasing a car). Because an Operating Lease does not contain any of the provisions that would qualify it as a Capital Lease, the lease is not treated as a sale or purchase and hits the lessee's rental expense and the lessor's revenue. So it all stays on the P&L (assuming no prepayments are made). Capital Leases, on the other hand, hit lessee's and lessor's balance sheets because the asset is treated as a sale. (I'm ignoring interest and depreciation here to emphasize my point). Question: What will happen to real estate leases when Operating Leases go away and how will Oracle Financials address these changes? Before I attempt to address these questions, here's a real-life example to expound on some of the issues: Let's say a U.S. retailer leases a store in a mall for 15 years. Under U.S. GAAP, the lease is considered an operating or expense lease. Will that same lease be considered a capital lease under IFRS? Real estate leases are supposedly going to be capitalized under IFRS. If so, will everyone need to change all leases from operating to capital? Or, could we make some adjustments so we report the lease as an expense for operations reporting but capitalize it for SEC reporting? Would all aspects of the lease be capitalized, or would some line items still be expensed? For example, many retail store leases are defined to include (1) the agreed-to rent amount; (2) a negotiated increase in base rent, e.g., maybe a 5% increase in Year 5; (3) a sales rent component whereby the retailer pays a variable additional amount based on the sales generated in the prior month; (4) parking lot maintenance fees. Would the entire lease be capitalized, or would some portions still be expensed? To help answer these questions, I met up with our resident accounting expert and walking encyclopedia, Seamus Moran. Here's what he had to say: Oracle is aware of the potential changes specific to reporting/capitalization of real estate leases; i.e., we are aware that FASB and IASB have identified real estate leases as one of the areas for standards convergence. Oracle stays apprised of the on-going convergence through our domain expertise staff, our relationship with customers, our market awareness, and, of course, our relationships with the Big 4. This is part of our normal process with respect to regulatory compliance worldwide. At this time, Oracle expects that the standards convergence committee will make a recommendation about reporting standards for real estate leases in about a year. Following typical procedures, we also expect that the recommendation will be up for review for a year, and customers will then need to start reporting to the new standard about a year after that. So that means we would expect the first customer to report under the new standard in maybe 3 years. Typically, after the new standard is finalized and distributed, we find that our customers then begin to evaluate how they plan to meet the new standard. And through groups like the Customer Advisory Boards (CABs), our customers tell us what kind of product changes are needed in order to satisfy their new reporting requirements. Of course, Oracle is also working with the Big 4 and Accenture and other implementers in order to ascertain that these recommended changes will indeed meet new reporting standards. So the best advice we can offer right now is, stay apprised of the standards convergence committee; know that Oracle is also staying abreast of developments; get involved with your CAB so your voice is heard; know that Oracle products continue to be GAAP compliant, and we will continue to maintain that as our standard. But exactly what is that "standard"--we need to wait on the standards convergence committee. In a nut shell, operating leases will become either capital leases or month to month rentals, but it is still too early, too political and too uncertain to call out at this point.

• Cloud Computing Architecture Patterns: Don’t Focus on the Client

  - by BuckWoody

  Normally I try to put topics in the positive in other words "Do this" not "Don't do that". Sometimes its clearer to focus on what *not* to do. Popular development processes often start with screen mockups, or user input descriptions. In a scale-out pattern like Cloud Computing on Windows Azure, that's the wrong place to start. Start with the Data    Instead, I recommend that you start with the data that a process requires. That data might be temporary or persisted, but starting with the data and its requirements helps to define not only the storage engine you need but also drives everything from security to the integrity of the application. For instance, assume the requirements show that the user must enter their phone number, and that this datum is used in a contact management system further down the application chain. For that datum, you can determine what data type you need (U.S. only or International?) the security requirements, whether it needs ACID compliance, how it will be searched, indexed and so on. From one small data point you can extrapolate out your options for storing and processing the data. Here's the interesting part, which begins to break the patterns that we've used for decades: all of the data doesn't have the same requirements. The phone number might be best suited for a list, or an element, or a string, with either BASE or ACID requirements, based on how it is used. That means we don't have to dump everything into XML, an RDBMS, a NoSQL engine, or a flat file exclusively. In fact, one record might use all of those depending on the use-case requirements. Next Is Data Management  With the data defined, we can move on to how to store the data. Again, the requirements now dictate whether we need a full relational calculus or set-based operations, or we can choose another method based on the requirements for the data. And breaking another pattern its OK to store in more than once, in more than one location. We do this all the time for reporting systems and Business Intelligence systems, so this is a pattern we need to think about even for OLTP data. Move to Data Transport How does the data get around? We can use a connection-based method, sending the data along a transport to the storage engine, but in some cases we may want to use a cache, a queue, the Service Bus, or Complex Event Processing. Finally, Data Processing Most RDBMS engines, NoSQL, and certainly Big Data engines not only store data, but can process and manipulate it as well. Its doubtful that you'll calculate that phone number right? Well, if you're the phone company, you most certainly will. And so we see that even once we've chosen the data type, storage and engine, the same element can have different computing requirements based on how it is used. Sure, We Need A Front-End At Some Point Not all data is entered by human hands in fact most data isn't. We don't really need a Graphical User Interface (GUI) we need some way for a GUI to get data into and out of the systems listed earlier.   But when we do need to allow users to enter or examine data, that should be left to the GUI that best fits the device the user has. Ever tried to use an application designed for a web browser on a phone? Or one designed for a tablet on a phone? Its usually quite painful. The siren song of "We'll just write one interface for all devices" is strong, and has beguiled many an unsuspecting architect. But they just don't work out.   Instead, focus on the data, its transport and processing. Create API calls or a message system that allows for resilient transport to the device or interface, and let it do what it does best.

• ASP.NET WebAPI Security 2: Identity Architecture

  - by Your DisplayName here!

  Pedro has beaten me to the punch with a detailed post (and diagram) about the WebAPI hosting architecture. So go read his post first, then come back so we can have a closer look at what that means for security. The first important takeaway is that WebAPI is hosting independent-  currently it ships with two host integration implementations – one for ASP.NET (aka web host) and WCF (aka self host). Pedro nicely shows the integration into the web host. Self hosting is not done yet so we will mainly focus on the web hosting case and I will point out security related differences when they exist. The interesting part for security (amongst other things of course) is the HttpControllerHandler (see Pedro’s diagram) – this is where the host specific representation of an HTTP request gets converted to the WebAPI abstraction (called HttpRequestMessage). The ConvertRequest method does the following: Create a new HttpRequestMessage. Copy URI, method and headers from the HttpContext. Copies HttpContext.User to the Properties<string, object> dictionary on the HttpRequestMessage. The key used for that can be found on HttpPropertyKeys.UserPrincipalKey (which resolves to “MS_UserPrincipal”). So the consequence is that WebAPI receives whatever IPrincipal has been set by the ASP.NET pipeline (in the web hosting case). Common questions are: Are there situations where is property does not get set? Not in ASP.NET – the DefaultAuthenticationModule in the HTTP pipeline makes sure HttpContext.User (and Thread.CurrentPrincipal – more on that later) are always set. Either to some authenticated user – or to an anonymous principal. This may be different in other hosting environments (again more on that later). Why so generic? Keep in mind that WebAPI is hosting independent and may run on a host that materializes identity completely different compared to ASP.NET (or .NET in general). This gives them a way to evolve the system in the future. How does WebAPI code retrieve the current client identity? HttpRequestMessage has an extension method called GetUserPrincipal() which returns the property as an IPrincipal. A quick look at self hosting shows that the moral equivalent of HttpControllerHandler.ConvertRequest() is HttpSelfHostServer.ProcessRequestContext(). Here the principal property gets only set when the host is configured for Windows authentication (inconsisteny). Do I like that? Well – yes and no. Here are my thoughts: I like that it is very straightforward to let WebAPI inherit the client identity context of the host. This might not always be what you want – think of an ASP.NET app that consists of UI and APIs – the UI might use Forms authentication, the APIs token based authentication. So it would be good if the two parts would live in a separate security world. It makes total sense to have this generic hand off point for identity between the host and WebAPI. It also makes total sense for WebAPI plumbing code (especially handlers) to use the WebAPI specific identity abstraction. But – c’mon we are running on .NET. And the way .NET represents identity is via IPrincipal/IIdentity. That’s what every .NET developer on this planet is used to. So I would like to see a User property of type IPrincipal on ApiController. I don’t like the fact that Thread.CurrentPrincipal is not populated. T.CP is a well established pattern as a one stop shop to retrieve client identity on .NET.  That makes a lot of sense – even if the name is misleading at best. There might be existing library code you want to call from WebAPI that makes use of T.CP (e.g. PrincipalPermission, or a simple .Name or .IsInRole()). Having the client identity as an ambient property is useful for code that does not have access to the current HTTP request (for calling GetUserPrincipal()). I don’t like the fact that that the client identity conversion from host to WebAPI is inconsistent. This makes writing security plumbing code harder. I think the logic should always be: If the host has a client identity representation, copy it. If not, set an anonymous principal on the request message. Btw – please don’t annoy me with the “but T.CP is static, and static is bad for testing” chant. T.CP is a getter/setter and, in fact I find it beneficial to be able to set different security contexts in unit tests before calling in some logic. And, in case you have wondered – T.CP is indeed thread static (and the name comes from a time where a logical operation was bound to a thread – which is not true anymore). But all thread creation APIs in .NET actually copy T.CP to the new thread they create. This is the case since .NET 2.0 and is certainly an improvement compared to how Win32 does things. So to sum it up: The host plumbing copies the host client identity to WebAPI (this is not perfect yet, but will surely be improved). or in other words: The current WebAPI bits don’t ship with any authentication plumbing, but solely use whatever authentication (and thus client identity) is set up by the host. WebAPI developers can retrieve the client identity from the HttpRequestMessage. Hopefully my proposed changes around T.CP and the User property on ApiController will be added. In the next post, I will detail how to add WebAPI specific authentication support, e.g. for Basic Authentication and tokens. This includes integrating the notion of claims based identity. After that we will look at the built-in authorization bits and how to improve them as well. Stay tuned.

• Getting to grips with the stack in nasm

  - by MarkPearl

  Today I spent a good part of my day getting to grips with the stack and nasm. After looking at my notes on nasm I think this is one area for the course I am doing they could focus more on… So here are some snippets I have put together that have helped me understand a little bit about the stack… Simplest example of the stack You will probably see examples like the following in circulation… these demonstrate the simplest use of the stack… org 0x100 bits 16 jmp main main: push 42h push 43h push 44h mov ah,2h ;set to display characters pop dx    ;get the first value int 21h   ;and display it pop dx    ;get 2nd value int 21h   ;and display it pop dx    ;get 3rd value int 21h   ;and display it int 20h The output from above code would be… DCB Decoupling code using “call” and “ret” This is great, but it oversimplifies what I want to use the stack for… I do not know if this goes against the grain of assembly programmers or not, but I want to write loosely coupled assembly code – and I want to use the stack as a mechanism for passing values into my decoupled code. In nasm we have the call and return instructions, which provides a mechanism for decoupling code, for example the following could be done… org 0x100 bits 16 jmp main ;---------------------------------------- displayChar: mov ah,2h mov dx,41h int 21h ret ;---------------------------------------- main: call displayChar int 20h   This would output the following to the console A So, it would seem that call and ret allow us to jump to segments of our code and then return back to the calling position – a form of segmenting the code into what we would called in higher order languages “functions” or “methods”. The only issue is, in higher order languages there is a way to pass parameters into the functions and return results. Because of the primitive nature of the call and ret instructions, this does not seem to be obvious. We could of course use the registers to pass values into the subroutine and set values coming out, but the problem with this is we… Have a limited number of registers Are threading our code with tight coupling (it would be hard to migrate methods outside of their intended use in a particular program to another one) With that in mind, I turn to the stack to provide a loosely coupled way of calling subroutines… First attempt with the Stack Initially I thought this would be simple… we could use code that looks as follows to achieve what I want… org 0x100 bits 16 jmp main ;---------------------------------------- displayChar: mov ah,2h pop dx int 21h ret ;---------------------------------------- main: push 41h call displayChar int 20h   However running this application does not give the desired result, I want an ‘A’ to be returned, and I am getting something totally different (you will to). Reading up on the call and ret instructions a discovery is made… they are pushing and popping things onto and off the stack as well… When the call instruction is executed, the current value of IP (the address of the instruction to follow) is pushed onto the stack, when ret is called, the last value on the stack is popped off into the IP register. In effect what the above code is doing is as follows with the stack… push 41h push current value of ip pop current value of ip to dx pop 41h to ip This is not what I want, I need to access the 41h that I pushed onto the stack, but the call value (which is necessary) is putting something in my way. So, what to do? Remember we have other registers we can use as well as a thing called indirect addressing… So, after some reading around, I came up with the following approach using indirect addressing… org 0x100 bits 16 jmp main ;---------------------------------------- displayChar: mov bp,sp mov ah,2h mov dx,[bp+2] int 21h ret ;---------------------------------------- main: push 41h call displayChar int 20h In essence, what I have done here is used a trick with the stack pointer… it goes as follows… Push 41 onto the stack Make the call to the function, which will push the IP register onto the stack and then jump to the displayChar label Move the value in the stack point to the bp register (sp currently points at IP register) Move the at the location of bp minus 2 bytes to dx (this is now the value 41h) display it, execute the ret instruction, which pops the ip value off the stack and goes back to the calling point This approach is still very raw, some further reading around shows that I should be pushing the value of bp onto the stack before replacing it with sp, but it is the starting thread to getting loosely coupled subroutines. Let’s see if you get what the following output would be? org 0x100 bits 16 jmp main ;---------------------------------------- displayChar: mov bp,sp mov ah,2h mov dx,[bp+4] int 21h mov dx,[bp+2] int 21h ret ;---------------------------------------- main: push 41h push 42h call displayChar int 20h The output is… AB Where to from here? If by any luck some assembly programmer comes along and see this code and notices that I have made some fundamental flaw in my logic… I would like to know, so please leave a comment… appreciate any feedback!
