  • How do I automatically download files to a Kindle 2 whenever its USB connection is plugged into a Windows 7 machine?

    - by Bob Cross
    The inspiration of this question is the Gadget Lab article How To Make Your Kindle Into an Automatic Instapaper. In that article, they describe an implementation of an Automator workflow that: Detects the connection of a portable disk (which the workflow assumes is the Kindle 2). Downloads the Instapaper mobi file containing the text version of the articles marked for "Read Later" to the computer. Downloads the mobi file from the computer to the Kindle 2. All of this is straightforward in terms of functionality but it is not immediately obvious how to do step 1 on a Windows box. Is the Task Scheduler the first step? If so, which event should be the trigger for the rest of the task?

  • Log off as local "administrator" user, get blank login screen

    - by Force Flow
    I have an imaged lab environment running Windows 7 and attached to a domain. The local Administrator account is enabled for certain maintenance and prep tasks. Every time I logoff from the local Administrator account, it brings me back to the standard Ctrl+Alt+Del login screen. When I press that combination, all the user controls vanish except for the accessibility button down in the left hand corner. The only way I can seem to escape from this is to tap the power button to initiate a shutdown. Windows is up-to-date, and logging off as any other user operates normally. The "hide last user" local security policy option is enabled. Has anyone seen this phenomenon before and how can I stop this from happening?

  • Undetected Virus? I study at College, and Now all of the school computers have paint.exe -autocheck

    - by Jeffy
    "C:\WINDOWS\system32\Paint.exe" -autocheck is added to the registry every time its removed. This is like global. All the lab PCs(more than a hundred), personal laptops have this file. I really have no expert help to turn to.. as jotti says this file is clean. Here's the dropped file [removed] It seems that we all had this game cheating tool on our PCs called "Garena Maphack". Everytime it was run it would drop paint.exe into the system dir. Paint.exe is diguised as the real paint.exe from windows. Having the same icon and such. Check out threat expert's report at threatexpert.com/report.aspx?md5=176288f6f22a80c76329853f8535d45b The game cheat that started this huge mess can be obtained from [removed] What do I do? any experts care to take apart this file?

  • Running Ubuntu off a USB drive?

    - by Solignis
    I was wondering if a USB 2.0 Thumb drive has enough bandwidth to act as a primary system drive in an Ubuntu Linux server. More specifically an SAN server. I am running an iSCSI target, ZFS and NFS-kernel-server, BIND9 (Slave), and Openldap (Slave). I was thinking of resorting to a thumb drive because my new motherboard only has 4 SATA ports and I have 5 disks. 4 (ZFS Pool) 1 (System). And unless I get an expansion card there is no way to get more SATA ports. This "server" leans more twords a home server. I use in my lab with my VMware server. It provides storage, or atleast it did until it died. Would it still be better to go with the SATA hard disk?

  • How do you automap List<float> or float[] with Fluent NHibernate?

    - by Tom Bushell
    Having successfully gotten a sample program working, I'm now starting to do Real Work with Fluent NHibernate - trying to use Automapping on my project's class heirarchy. It's a scientific instrumentation application, and the classes I'm mapping have several properties that are arrays of floats e.g. private float[] _rawY; public virtual float[] RawY { get { return _rawY; } set { _rawY = value; } } These arrays can contain a maximum of 500 values. I didn't expect Automapping to work on arrays, but tried it anyway, with some success at first. Each array was auto mapped to a BLOB (using SQLite), which seemed like a viable solution. The first problem came when I tried to call SaveOrUpdate on the objects containing the arrays - I got "No persister for float[]" exceptions. So my next thought was to convert all my arrays into ILists e.g. public virtual IList<float> RawY { get; set; } But now I get: NHibernate.MappingException: Association references unmapped class: System.Single Since Automapping can deal with lists of complex objects, it never occured to me it would not be able to map lists of basic types. But after doing some Googling for a solution, this seems to be the case. Some people seem to have solved the problem, but the sample code I saw requires more knowledge of NHibernate than I have right now - I didn't understand it. Questions: 1. How can I make this work with Automapping? 2. Also, is it better to use arrays or lists for this application? I can modify my app to use either if necessary (though I prefer lists). Edit: I've studied the code in Mapping Collection of Strings, and I see there is test code in the source that sets up an IList of strings, e.g. public virtual IList<string> ListOfSimpleChildren { get; set; } [Test] public void CanSetAsElement() { new MappingTester<OneToManyTarget>() .ForMapping(m => m.HasMany(x => x.ListOfSimpleChildren).Element("columnName")) .Element("class/bag/element").Exists(); } so this must be possible using pure Automapping, but I've had zero luck getting anything to work, probably because I don't have the requisite knowlege of manually mapping with NHibernate. Starting to think I'm going to have to hack this (by encoding the array of floats as a single string, or creating a class that contains a single float which I then aggregate into my lists), unless someone can tell me how to do it properly. End Edit Here's my CreateSessionFactory method, if that helps formulate a reply... private static ISessionFactory CreateSessionFactory() { ISessionFactory sessionFactory = null; const string autoMapExportDir = "AutoMapExport"; if( !Directory.Exists(autoMapExportDir) ) Directory.CreateDirectory(autoMapExportDir); try { var autoPersistenceModel = AutoMap.AssemblyOf<DlsAppOverlordExportRunData>() .Where(t => t.Namespace == "DlsAppAutomapped") .Conventions.Add( DefaultCascade.All() ) ; sessionFactory = Fluently.Configure() .Database(SQLiteConfiguration.Standard .UsingFile(DbFile) .ShowSql() ) .Mappings(m => m.AutoMappings.Add(autoPersistenceModel) .ExportTo(autoMapExportDir) ) .ExposeConfiguration(BuildSchema) .BuildSessionFactory() ; } catch (Exception e) { Debug.WriteLine(e); } return sessionFactory; }

  • Lightweight use of Enterprise Library TraceListeners

    - by gWiz
    Is it possible to use the Enterprise Library 4.1 TraceListeners without using the entire Enterprise Library Logging AB? I'd prefer to simply use .NET Diagnostics Tracing, but would like to setup a listener that sends emails on Error events. I figured I could use the Enterprise Library EmailTraceListener. However, my initial attempts to configure it have failed. Here's what I hoped would work: <system.diagnostics> <trace autoflush="false" /> <sources> <source name="SampleSource" switchValue="Verbose" > <listeners> <add name="textFileListener" /> <add name="emailListener" /> </listeners> </source> </sources> <sharedListeners> <add name="textFileListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="..\trace.log" traceOutputOptions="DateTime"> <filter type="System.Diagnostics.EventTypeFilter" initializeData="Verbose" /> </add> <add name="emailListener" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.EmailTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging" toAddress="[email protected]" fromAddress="[email protected]" smtpServer="mail.example.com" > <filter type="System.Diagnostics.EventTypeFilter" initializeData="Verbose" /> </add> </sharedListeners> </system.diagnostics> However I get [ArgumentException: The parameter 'address' cannot be an empty string. Parameter name: address] System.Net.Mail.MailAddress..ctor(String address, String displayName, Encoding displayNameEncoding) +1098157 System.Net.Mail.MailAddress..ctor(String address) +8 Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.EmailMessage.CreateMailMessage() +256 Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.EmailMessage.Send() +39 Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.EmailTraceListener.Write(String message) +96 System.Diagnostics.TraceListener.WriteHeader(String source, TraceEventType eventType, Int32 id) +184 System.Diagnostics.TraceListener.TraceEvent(TraceEventCache eventCache, String source, TraceEventType eventType, Int32 id, String format, Object[] args) +63 System.Diagnostics.TraceSource.TraceEvent(TraceEventType eventType, Int32 id, String format, Object[] args) +198 System.Diagnostics.TraceSource.TraceInformation(String message) +14 Which leads me to believe the .NET Tracing code does not care about the "non-standard" config attributes I've supplied for emailListener. I also tried adding the appropriate LAB configSection declaration and: <loggingConfiguration> <listeners> <add toAddress="[email protected]" fromAddress="[email protected]" smtpServer="mail.example.com" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.EmailTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging" name="emailListener" /> </listeners> </loggingConfiguration> This also results in the same exception. I figure it's possible to programmatically configure the EmailTraceListener, but I prefer this to be config-driven. I also understand I can implement my own derivative of TraceListener. So, is it possible to use the Ent Lib TraceListeners, without using the whole Ent Lib LAB, and configure them from the config file? Update: After examining the code, I have discovered it is not possible. The Ent Lib TraceListeners do not actually utilize the config attributes they specify in overriding TraceListener.GetSupportedAttributes(), despite the recommendations in the .NET TraceListener documentation. Bug filed.

  • C++/msvc6 application crashes due to heap corruption, any hints?

    - by David Alfonso
    Hello all, let me say first that I'm writing this question after months of trying to find out the root of a crash happening in our application. I'll try to detail as much as possible what I've already found out about it. About the application It runs on Windows XP Professional SP2. It's built with Microsoft Visual C++ 6.0 with Service Pack 6. It's MFC based. It uses several external dlls (e.g. Xerces, ZLib or ACE). It has high performance requirements. It does a lot of network and hard disk I/O, but it's also cpu intensive. It has an exception handling mechanism which generates a minidump when an unhandled exception occurs. Facts about the crash It only happens on multiprocessor/multicore machines and under heavy loads of work. It happens at random (neither we nor our client have found a pattern yet). We cannot reproduce the crash on our testing lab. It only happens on some production systems (but always in multicore machines) It always ends up crashing at the same point, although the complete stack is not always the same. Let me add the stack of the crashing thread (obtained using WinDbg, sorry we don't have symbols) ChildEBP RetAddr Args to Child WARNING: Stack unwind information not available. Following frames may be wrong. 030af6c8 7c9206eb 77bfc3c9 01a80000 00224bc3 MyApplication+0x2a85b9 030af960 7c91e9c0 7c92901b 00000ab4 00000000 ntdll!RtlAllocateHeap+0xeac (FPO: [Non-Fpo]) 030af98c 7c9205c8 00000001 00000000 00000000 ntdll!ZwWaitForSingleObject+0xc (FPO: [3,0,0]) 030af9c0 7c920551 01a80898 7c92056d 313adfb0 ntdll!RtlpFreeToHeapLookaside+0x22 (FPO: [2,0,4]) 030afa8c 4ba3ae96 000307da 00130005 00040012 ntdll!RtlFreeHeap+0x1e9 (FPO: [Non-Fpo]) 030afacc 77bfc2e3 0214e384 3087c8d8 02151030 0x4ba3ae96 030afb00 7c91e306 7c80bfc1 00000948 00000001 msvcrt!free+0xc8 (FPO: [Non-Fpo]) 030afb20 0042965b 030afcc0 0214d780 02151218 ntdll!ZwReleaseSemaphore+0xc (FPO: [3,0,0]) 030afb7c 7c9206eb 02e6c471 02ea0000 00000008 MyApplication+0x2965b 030afe60 7c9205c8 02151248 030aff38 7c920551 ntdll!RtlAllocateHeap+0xeac (FPO: [Non-Fpo]) 030afe74 7c92056d 0210bfb8 02151250 02151250 ntdll!RtlpFreeToHeapLookaside+0x22 (FPO: [2,0,4]) 030aff38 77bfc2de 01a80000 00000000 77bfc2e3 ntdll!RtlFreeHeap+0x647 (FPO: [Non-Fpo]) 7c92056d c5ffffff ce7c94be ff7c94be 00ffffff msvcrt!free+0xc3 (FPO: [Non-Fpo]) 7c920575 ff7c94be 00ffffff 12000000 907c94be 0xc5ffffff 7c920579 00ffffff 12000000 907c94be 90909090 0xff7c94be *** WARNING: Unable to verify checksum for xerces-c_2_7.dll *** ERROR: Symbol file could not be found.

What I have tried so far Reviewing all the code related to the point where the crash ends happening. Trying to enable pageheap on our testing lab though nothing useful has been found by now. We have substituted the std::list for a C array and then it crashes in other part of the code (although it is related code, it's not in the code where the old list resided). Coincidentally, now it crashes in another erase, though this time of a std::multiset. Let me copy the stack contained in the dump: ntdll.dll!_RtlpCoalesceFreeBlocks@16() + 0x124e bytes ntdll.dll!_RtlFreeHeap@12() + 0x91f bytes msvcrt.dll!_free() + 0xc3 bytes MyApplication.exe!006a4fda() [Frames below may be incorrect and/or missing, no symbols loaded for MyApplication.exe] MyApplication.exe!0069f305() ntdll.dll!_NtFreeVirtualMemory@16() + 0xc bytes ntdll.dll!_RtlpSecMemFreeVirtualMemory@16() + 0x1b bytes ntdll.dll!_ZwWaitForSingleObject@12() + 0xc bytes ntdll.dll!_RtlpFreeToHeapLookaside@8() + 0x26 bytes ntdll.dll!_RtlFreeHeap@12() + 0x114 bytes msvcrt.dll!_free() + 0xc3 bytes c5ffffff() Possible solutions (that I'm aware of) which cannot be applied "Migrate the application to a newer compiler": We are working on this but It's not a solution at the moment. "Enable pageheap (normal or full)": We can't enable pageheap on production machines as this affects performance heavily. I think that's all I remember now, if I have forgotten something I'll add it asap. If you can give me some hint or propose some possible solution, don't hesitate to answer! Thank you in advance for your time and advice.

  • Make interchangeable class types via pointer casting only, without having to allocate any new objects?

    - by HostileFork
    UPDATE: I do appreciate "don't want that, want this instead" suggestions. They are useful, especially when provided in context of the motivating scenario. Still...regardless of goodness/badness, I've become curious to find a hard-and-fast "yes that can be done legally in C++11" vs "no it is not possible to do something like that". I want to "alias" an object pointer as another type, for the sole purpose of adding some helper methods. The alias cannot add data members to the underlying class (in fact, the more I can prevent that from happening the better!) All aliases are equally applicable to any object of this type...it's just helpful if the type system can hint which alias is likely the most appropriate. There should be no information about any specific alias that is ever encoded in the underlying object. Hence, I feel like you should be able to "cheat" the type system and just let it be an annotation...checked at compile time, but ultimately irrelevant to the runtime casting. Something along these lines: Node<AccessorFoo>* fooPtr = Node<AccessorFoo>::createViaFactory(); Node<AccessorBar>* barPtr = reinterpret_cast< Node<AccessorBar>* >(fooPtr); Under the hood, the factory method is actually making a NodeBase class, and then using a similar reinterpret_cast to return it as a Node<AccessorFoo>*. The easy way to avoid this is to make these lightweight classes that wrap nodes and are passed around by value. Thus you don't need casting, just Accessor classes that take the node handle to wrap in their constructor: AccessorFoo foo (NodeBase::createViaFactory()); AccessorBar bar (foo.getNode()); But if I don't have to pay for all that, I don't want to. That would involve--for instance--making a special accessor type for each sort of wrapped pointer (AccessorFooShared, AccessorFooUnique, AccessorFooWeak, etc.) Having these typed pointers being aliased for one single pointer-based object identity is preferable, and provides a nice orthogonality. So back to that original question: Node<AccessorFoo>* fooPtr = Node<AccessorFoo>::createViaFactory(); Node<AccessorBar>* barPtr = reinterpret_cast< Node<AccessorBar>* >(fooPtr); Seems like there would be some way to do this that might be ugly but not "break the rules". According to ISO14882:2011(e) 5.2.10-7: An object pointer can be explicitly converted to an object pointer of a different type.70 When a prvalue v of type "pointer to T1" is converted to the type "pointer to cv T2", the result is static_cast(static_cast(v)) if both T1 and T2 are standard-layout types (3.9) and the alignment requirements of T2 are no stricter than those of T1, or if either type is void. Converting a prvalue of type "pointer to T1" to the type "pointer to T2" (where T1 and T2 are object types and where the alignment requirements of T2 are no stricter than those of T1) and back to its original type yields the original pointer value. The result of any other such pointer conversion is unspecified. Drilling into the definition of a "standard-layout class", we find: has no non-static data members of type non-standard-layout-class (or array of such types) or reference, and has no virtual functions (10.3) and no virtual base classes (10.1), and has the same access control (clause 11) for all non-static data members, and has no non-standard-layout base classes, and either has no non-static data member in the most-derived class and at most one base class with non-static data members, or has no base classes with non-static data members, and has no base classes of the same type as the first non-static data member. Sounds like working with something like this would tie my hands a bit with no virtual methods in the accessors or the node. Yet C++11 apparently has std::is_standard_layout to keep things checked. Can this be done safely? Appears to work in gcc-4.7, but I'd like to be sure I'm not invoking undefined behavior.

  • Problems with passing an anonymous temporary function-object to a templatized constructor.

    - by Akanksh
    I am trying to attach a function-object to be called on destruction of a templatized class. However, I can not seem to be able to pass the function-object as a temporary. The warning I get is (if the comment the line xi.data = 5;): warning C4930: 'X<T> xi2(writer (__cdecl *)(void))': prototyped function not called (was a variable definition intended?) with [ T=int ] and if I try to use the constructed object, I get a compilation error saying: error C2228: left of '.data' must have class/struct/union I apologize for the lengthy piece of code, but I think all the components need to be visible to assess the situation. template<typename T> struct Base { virtual void run( T& ){} virtual ~Base(){} }; template<typename T, typename D> struct Derived : public Base<T> { virtual void run( T& t ) { D d; d(t); } }; template<typename T> struct X { template<typename R> X(const R& r) { std::cout << "X(R)" << std::endl; ptr = new Derived<T,R>(); } X():ptr(0) { std::cout << "X()" << std::endl; } ~X() { if(ptr) { ptr->run(data); delete ptr; } else { std::cout << "no ptr" << std::endl; } } Base<T>* ptr; T data; }; struct writer { template<typename T> void operator()( const T& i ) { std::cout << "T : " << i << std::endl; } }; int main() { { writer w; X<int> xi2(w); //X<int> xi2(writer()); //This does not work! xi2.data = 15; } return 0; }; The reason I am trying this out is so that I can "somehow" attach function-objects types with the objects without keeping an instance of the function-object itself within the class. Thus when I create an object of class X, I do not have to keep an object of class writer within it, but only a pointer to Base<T> (I'm not sure if I need the <T> here, but for now its there). The problem is that I seem to have to create an object of writer and then pass it to the constructor of X rather than call it like X<int> xi(writer(); I might be missing something completely stupid and obvious here, any suggestions?

  • Javascript parent and child window functions

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE>Lab 9-3</TITLE> <SCRIPT LANGUAGE="JavaScript"> <!-- function myFunction(){ myWin = open("","","width=200,height=200"); with(myWin.document){ open(); write("<HTML><HEAD><TITLE>Child Window</TITLE>"); write("<SCRIPT>function myTest(){"); write("alert('This function is defined in the child window "); write("and is called from the parent window.'); this.focus();}"); write("</SCRIPT></HEAD><BODY><H3>Child Window</H3><HR>"); write("<FORM><INPUT TYPE='button' VALUE='parent window function' "); // Use opener property write("onClick='opener.winFunction();'>"); write("<P><INPUT TYPE='button' VALUE='close window' "); write("onClick='window.close();'>"); write("</FORM></BODY></HTML>"); close(); } } function winFunction(){ alert("This function is defined in the parent window\n" + "and is called from the child window."); myWin.focus(); } //--> </SCRIPT> </HEAD> <BODY> <H3>CIW Web Languages</H3> <HR> <FORM NAME="myForm"> <INPUT TYPE="button" VALUE="open new window" onClick="myFunction();"> <!-- Invoke child window function --> <input type="button" value="Click to open child window" onclick="javascript:void(myWin.myTest());"/> </FORM> <P> </BODY> </HTML> To explain further what my initial query was, the code above, should open the child window (myWin) with the second button, the 'Open child window' button without the need to open the window with the first button or do anything else. It should simply call the myWin.myTest()function The child window will open when the second button is pressed but needs to have the child window open first (first button push) before it'll work. This is not the intended purpose, the 'Open child window' button should work without anything else needing to be done. For some reason the parent window isn't communicating with the myWin window and myTest fucntion. It's not homework, it's part of a certification course lab and is coded in the manner I have been shown to understand as correct. DTD isn't included as the focus is the JavaScript. I code correctly with regards to that and other W3C requirements.

  • How to reserve public API to internal usage in .NET?

    - by mark
    Dear ladies and sirs. Let me first present the case, which will explain my question. This is going to be a bit long, so I apologize in advance :-). I have objects and collections, which should support the Merge API (it is my custom API, the signature of which is immaterial for this question). This API must be internal, meaning only my framework should be allowed to invoke it. However, derived types should be able to override the basic implementation. The natural way to implement this pattern as I see it, is this: The Merge API is declared as part of some internal interface, let us say IMergeable. Because the interface is internal, derived types would not be able to implement it directly. Rather they must inherit it from a common base type. So, a common base type is introduced, which would implement the IMergeable interface explicitly, where the interface methods delegate to respective protected virtual methods, providing the default implementation. This way the API is only callable by my framework, but derived types may override the default implementation. The following code snippet demonstrates the concept: internal interface IMergeable { void Merge(object obj); } public class BaseFrameworkObject : IMergeable { protected virtual void Merge(object obj) { // The default implementation. } void IMergeable.Merge(object obj) { Merge(obj); } } public class SomeThirdPartyObject : BaseFrameworkObject { protected override void Merge(object obj) { // A derived type implementation. } } All is fine, provided a single common base type suffices, which is usually true for non collection types. The thing is that collections must be mergeable as well. Collections do not play nicely with the presented concept, because developers do not develop collections from the scratch. There are predefined implementations - observable, filtered, compound, read-only, remove-only, ordered, god-knows-what, ... They may be developed from scratch in-house, but once finished, they serve wide range of products and should never be tailored to some specific product. Which means, that either: they do not implement the IMergeable interface at all, because it is internal to some product the scope of the IMergeable interface is raised to public and the API becomes open and callable by all. Let us refer to these collections as standard collections. Anyway, the first option screws my framework, because now each possible standard collection type has to be paired with the respective framework version, augmenting the standard with the IMergeable interface implementation - this is so bad, I am not even considering it. The second option breaks the framework as well, because the IMergeable interface should be internal for a reason (whatever it is) and now this interface has to open to all. So what to do? My solution is this. make IMergeable public API, but add an extra parameter to the Merge method, I call it a security token. The interface implementation may check that the token references some internal object, which is never exposed to the outside. If this is the case, then the method was called from within the framework, otherwise - some outside API consumer attempted to invoke it and so the implementation can blow up with a SecurityException. Here is the modified code snippet demonstrating this concept: internal static class InternalApi { internal static readonly object Token = new object(); } public interface IMergeable { void Merge(object obj, object token); } public class BaseFrameworkObject : IMergeable { protected virtual void Merge(object obj) { // The default implementation. } public void Merge(object obj, object token) { if (!object.ReferenceEquals(token, InternalApi.Token)) { throw new SecurityException("bla bla bla"); } Merge(obj); } } public class SomeThirdPartyObject : BaseFrameworkObject { protected override void Merge(object obj) { // A derived type implementation. } } Of course, this is less explicit than having an internally scoped interface and the check is moved from the compile time to run time, yet this is the best I could come up with. Now, I have a gut feeling that there is a better way to solve the problem I have presented. I do not know, may be using some standard Code Access Security features? I have only vague understanding of it, but can LinkDemand attribute be somehow related to it? Anyway, I would like to hear other opinions. Thanks.

  • MySQL Connect: What to Expect From the Wondrous Land of MySQL Cluster

    - by Mat Keep
    The MySQL Connect conference is only a couple of weeks away, with MySQL engineers, support teams, consultants and community aces busy putting the final touches to their talks. There will be many exciting new announcements and sharing of best practices at the conference, covering the range of MySQL technologies. MySQL Cluster will a big part of this, so I wanted to share some key sessions for those of you who plan on attending, as well as some resources for those who are not lucky enough to be able to make the trip, but who can't afford to miss the key news. Of course, this is no substitute to actually being there….and the good news is that registration is still open ;-) Roadmap: Whats New in MySQL Cluster Saturday 29th, 1300-1400, in Golden Gate room 5.                                                                                        Bernd Ocklin, director of MySQL Cluster development, and myself will be taking a look at what follows the latest MySQL Cluster 7.2 release.

  • DirectCompute

    In my previous blog post I introduced the concept of GPGPU ending with:On Windows, there is already a cross-GPU-vendor way of programming GPUs and that is the Direct X API. Specifically, on Windows Vista and Windows 7, the DirectX 11 API offers a dedicated subset of the API for GPGPU programming: DirectCompute. You use this API on the CPU side, to set up and execute the kernels on the GPU. The kernels are written in a language called HLSL (High Level Shader Language). You can use DirectCompute with HLSL to write a "compute shader", which is the term DirectX uses for what I've been referring to in this post as "kernel".In this post I want to share some links to get you started with DirectCompute and HLSL.1. Watch the recording of the PDC 09 session: DirectX11 DirectCompute.2. If session recordings is your thing there are two more on DirectCompute from nvidia's GTC09 conference 1015 (pdf, mp4) and 1411 (mp4 plus the presenter's written version of the session).3. Over at gamedev there is an old Compute Shader tutorial. At the same site, there is a 3-part blog post on Compute Shader: Introduction, Resources and Addressing.4. From PDC, you can also download the DirectCompute Hands On Lab.5. When you are ready to get your hands even dirtier, download the latest Windows DirectX SDK (at the time of writing the latest is dated Feb 2010).6. Within the SDK you'll find a Compute Shader Overview and samples such as: Basic, Sort, OIT, NBodyGravity, HDR Tone Mapping.7. Talking of DX11/DirectCompute samples, there are also a couple of good ones on this URL.8. The documentation of the various APIs is available online. Here are just some good (but far from complete) taster entry points into that: numthreads, SV_DispatchThreadID, SV_GroupThreadID, SV_GroupID, SV_GroupIndex, D3D11CreateDevice, D3DX11CompileFromFile, CreateComputeShader, Dispatch, D3D11_BIND_FLAG, GSSetShader. Comments about this post welcome at the original blog.

  • Anunciando: Grandes Melhorias para Web Sites da Windows Azure

    - by Leniel Macaferi
    Estou animado para anunciar algumas grandes melhorias para os Web Sites da Windows Azure que introduzimos no início deste verão.  As melhorias de hoje incluem: uma nova opção de hospedagem adaptável compartilhada de baixo custo, suporte a domínios personalizados para websites hospedados em modo compartilhado ou em modo reservado usando registros CNAME e A-Records (o último permitindo naked domains), suporte para deployment contínuo usando tanto CodePlex e GitHub, e a extensibilidade FastCGI. Todas essas melhorias estão agora online em produção e disponíveis para serem usadas imediatamente. Nova Camada Escalonável "Compartilhada" A Windows Azure permite que você implante e hospede até 10 websites em um ambiente gratuito e compartilhado com múltiplas aplicações. Você pode começar a desenvolver e testar websites sem nenhum custo usando este modo compartilhado (gratuito). O modo compartilhado suporta a capacidade de executar sites que servem até 165MB/dia de conteúdo (5GB/mês). Todas as capacidades que introduzimos em Junho com esta camada gratuita permanecem inalteradas com a atualização de hoje. Começando com o lançamento de hoje, você pode agora aumentar elasticamente seu website para além desta capacidade usando uma nova opção "shared" (compartilhada) de baixo custo (a qual estamos apresentando hoje), bem como pode usar a opção "reserved instance" (instância reservada) - a qual suportamos desde Junho. Aumentar a capacidade de qualquer um desses modos é fácil. Basta clicar na aba "scale" (aumentar a capacidade) do seu website dentro do Portal da Windows Azure, escolher a opção de modo de hospedagem que você deseja usar com ele, e clicar no botão "Salvar". Mudanças levam apenas alguns segundos para serem aplicadas e não requerem nenhum código para serem alteradas e também não requerem que a aplicação seja reimplantada/reinstalada: A seguir estão mais alguns detalhes sobre a nova opção "shared" (compartilhada), bem como a opção existente "reserved" (reservada): Modo Compartilhado Com o lançamento de hoje, estamos introduzindo um novo modo de hospedagem de baixo custo "compartilhado" para Web Sites da Windows Azure. Um website em execução no modo compartilhado é implantado/instalado em um ambiente de hospedagem compartilhado com várias outras aplicações. Ao contrário da opção de modo free (gratuito), um web-site no modo compartilhado não tem quotas/limite máximo para a quantidade de largura de banda que o mesmo pode servir. Os primeiros 5 GB/mês de banda que você servir com uma website compartilhado é grátis, e então você passará a pagar a taxa padrão "pay as you go" (pague pelo que utilizar) da largura de banda de saída da Windows Azure quando a banda de saída ultrapassar os 5 GB. Um website em execução no modo compartilhado agora também suporta a capacidade de mapear múltiplos nomes de domínio DNS personalizados, usando ambos CNAMEs e A-records para tanto. O novo suporte A-record que estamos introduzindo com o lançamento de hoje oferece a possibilidade para você suportar "naked domains" (domínios nús - sem o www) com seus web-sites (por exemplo, http://microsoft.com além de http://www.microsoft.com). Nós também, no futuro, permitiremos SSL baseada em SNI como um recurso nativo nos websites que rodam em modo compartilhado (esta funcionalidade não é suportada com o lançamento de hoje - mas chagará mais tarde ainda este ano, para ambos as opções de hospedagem - compartilhada e reservada). Você paga por um website no modo compartilhado utilizando o modelo padrão "pay as you go" que suportamos com outros recursos da Windows Azure (ou seja, sem custos iniciais, e você só paga pelas horas nas quais o recurso estiver ativo). Um web-site em execução no modo compartilhado custa apenas 1,3 centavos/hora durante este período de preview (isso dá uma média de $ 9.36/mês ou R$ 19,00/mês - dólar a R$ 2,03 em 17-Setembro-2012) Modo Reservado Além de executar sites em modo compartilhado, também suportamos a execução dos mesmos dentro de uma instância reservada. Quando rodando em modo de instância reservada, seus sites terão a garantia de serem executados de maneira isolada dentro de sua própria VM (virtual machine - máquina virtual) Pequena, Média ou Grande (o que significa que, nenhum outro cliente da Windows azure terá suas aplicações sendo executadas dentro de sua VM. Somente as suas aplicações). Você pode executar qualquer número de websites dentro de uma máquina virtual, e não existem quotas para limites de CPU ou memória. Você pode executar seus sites usando uma única VM de instância reservada, ou pode aumentar a capacidade tendo várias instâncias (por exemplo, 2 VMs de médio porte, etc.). Dimensionar para cima ou para baixo é fácil - basta selecionar a VM da instância "reservada" dentro da aba "scale" no Portal da Windows Azure, escolher o tamanho da VM que você quer, o número de instâncias que você deseja executar e clicar em salvar. As alterações têm efeito em segundos: Ao contrário do modo compartilhado, não há custo por site quando se roda no modo reservado. Em vez disso, você só paga pelas instâncias de VMs reservadas que você usar - e você pode executar qualquer número de websites que você quiser dentro delas, sem custo adicional (por exemplo, você pode executar um único site dentro de uma instância de VM reservada ou 100 websites dentro dela com o mesmo custo). VMs de instâncias reservadas têm um custo inicial de $ 8 cents/hora ou R$ 16 centavos/hora para uma pequena VM reservada. Dimensionamento Elástico para Cima/para Baixo Os Web Sites da Windows Azure permitem que você dimensione para cima ou para baixo a sua capacidade dentro de segundos. Isso permite que você implante um site usando a opção de modo compartilhado, para começar, e em seguida, dinamicamente aumente a capacidade usando a opção de modo reservado somente quando você precisar - sem que você tenha que alterar qualquer código ou reimplantar sua aplicação. Se o tráfego do seu site diminuir, você pode diminuir o número de instâncias reservadas que você estiver usando, ou voltar para a camada de modo compartilhado - tudo em segundos e sem ter que mudar o código, reimplantar a aplicação ou ajustar os mapeamentos de DNS. Você também pode usar o "Dashboard" (Painel de Controle) dentro do Portal da Windows Azure para facilmente monitorar a carga do seu site em tempo real (ele mostra não apenas as solicitações/segundo e a largura de banda consumida, mas também estatísticas como a utilização de CPU e memória). Devido ao modelo de preços "pay as you go" da Windows Azure, você só paga a capacidade de computação que você usar em uma determinada hora. Assim, se o seu site está funcionando a maior parte do mês em modo compartilhado (a $ 1.3 cents/hora ou R$ 2,64 centavos/hora), mas há um final de semana em que ele fica muito popular e você decide aumentar sua capacidade colocando-o em modo reservado para que seja executado em sua própria VM dedicada (a $ 8 cents/hora ou R$ 16 centavos/hora), você só terá que pagar os centavos/hora adicionais para as horas em que o site estiver sendo executado no modo reservado. Você não precisa pagar nenhum custo inicial para habilitar isso, e uma vez que você retornar seu site para o modo compartilhado, você voltará a pagar $ 1.3 cents/hora ou R$ 2,64 centavos/hora). Isto faz com que essa opção seja super flexível e de baixo custo. Suporte Melhorado para Domínio Personalizado Web sites em execução no modo "compartilhado" ou no modo "reservado" suportam a habilidade de terem nomes personalizados (host names) associados a eles (por exemplo www.mysitename.com). Você pode associar múltiplos domínios personalizados para cada Web Site da Windows Azure. Com o lançamento de hoje estamos introduzindo suporte para registros A-Records (um recurso muito pedido pelos usuários). Com o suporte a A-Record, agora você pode associar domínios 'naked' ao seu Web Site da Windows Azure - ou seja, em vez de ter que usar www.mysitename.com você pode simplesmente usar mysitename.com (sem o prefixo www). Tendo em vista que você pode mapear vários domínios para um único site, você pode, opcionalmente, permitir ambos domínios (com www e a versão 'naked') para um site (e então usar uma regra de reescrita de URL/redirecionamento (em Inglês) para evitar problemas de SEO). Nós também melhoramos a interface do usuário para o gerenciamento de domínios personalizados dentro do Portal da Windows Azure como parte do lançamento de hoje. Clicando no botão "Manage Domains" (Gerenciar Domínios) na bandeja na parte inferior do portal agora traz uma interface de usuário personalizada que torna fácil gerenciar/configurar os domínios: Como parte dessa atualização nós também tornamos significativamente mais suave/mais fácil validar a posse de domínios personalizados, e também tornamos mais fácil alternar entre sites/domínios existentes para Web Sites da Windows Azure, sem que o website fique fora do ar. Suporte a Deployment (Implantação) contínua com Git e CodePlex ou GitHub Um dos recursos mais populares que lançamos no início deste verão foi o suporte para a publicação de sites diretamente para a Windows Azure usando sistemas de controle de código como TFS e Git. Esse recurso fornece uma maneira muito poderosa para gerenciar as implantações/instalações da aplicação usando controle de código. É realmente fácil ativar este recurso através da página do dashboard de um web site: A opção TFS que lançamos no início deste verão oferece uma solução de implantação contínua muito rica que permite automatizar os builds e a execução de testes unitários a cada vez que você atualizar o repositório do seu website, e em seguida, se os testes forem bem sucedidos, a aplicação é automaticamente publicada/implantada na Windows Azure. Com o lançamento de hoje, estamos expandindo nosso suporte Git para também permitir cenários de implantação contínua integrando esse suporte com projetos hospedados no CodePlex e no GitHub. Este suporte está habilitado para todos os web-sites (incluindo os que usam o modo "free" (gratuito)). A partir de hoje, quando você escolher o link "Set up Git publishing" (Configurar publicação Git) na página do dashboard de um website, você verá duas opções adicionais quando a publicação baseada em Git estiver habilitada para o web-site: Você pode clicar em qualquer um dos links "Deploy from my CodePlex project" (Implantar a partir do meu projeto no CodePlex) ou "Deploy from my GitHub project"  (Implantar a partir do meu projeto no GitHub) para seguir um simples passo a passo para configurar uma conexão entre o seu website e um repositório de código que você hospeda no CodePlex ou no GitHub. Uma vez que essa conexão é estabelecida, o CodePlex ou o GitHub automaticamente notificará a Windows Azure a cada vez que um checkin ocorrer. Isso fará com que a Windows Azure faça o download do código e compile/implante a nova versão da sua aplicação automaticamente.  Os dois vídeos a seguir (em Inglês) mostram quão fácil é permitir esse fluxo de trabalho ao implantar uma app inicial e logo em seguida fazer uma alteração na mesma: Habilitando Implantação Contínua com os Websites da Windows Azure e CodePlex (2 minutos) Habilitando Implantação Contínua com os Websites da Windows Azure e GitHub (2 minutos) Esta abordagem permite um fluxo de trabalho de implantação contínua realmente limpo, e torna muito mais fácil suportar um ambiente de desenvolvimento em equipe usando Git: Nota: o lançamento de hoje suporta estabelecer conexões com repositórios públicos do GitHub/CodePlex. Suporte para repositórios privados será habitado em poucas semanas. Suporte para Múltiplos Branches (Ramos de Desenvolvimento) Anteriormente, nós somente suportávamos implantar o código que estava localizado no branch 'master' do repositório Git. Muitas vezes, porém, os desenvolvedores querem implantar a partir de branches alternativos (por exemplo, um branch de teste ou um branch com uma versão futura da aplicação). Este é agora um cenário suportado - tanto com projetos locais baseados no git, bem como com projetos ligados ao CodePlex ou GitHub. Isto permite uma variedade de cenários úteis. Por exemplo, agora você pode ter dois web-sites - um em "produção" e um outro para "testes" - ambos ligados ao mesmo repositório no CodePlex ou no GitHub. Você pode configurar um dos websites de forma que ele sempre baixe o que estiver presente no branch master, e que o outro website sempre baixe o que estiver no branch de testes. Isto permite uma maneira muito limpa para habilitar o teste final de seu site antes que ele entre em produção. Este vídeo de 1 minuto (em Inglês) demonstra como configurar qual branch usar com um web-site. Resumo Os recursos mostrados acima estão agora ao vivo em produção e disponíveis para uso imediato. Se você ainda não tem uma conta da Windows Azure, você pode inscrever-se em um teste gratuito para começar a usar estes recursos hoje mesmo. Visite o O Centro de Desenvolvedores da Windows Azure (em Inglês) para saber mais sobre como criar aplicações para serem usadas na nuvem. Nós teremos ainda mais novos recursos e melhorias chegando nas próximas semanas - incluindo suporte para os recentes lançamentos do Windows Server 2012 e .NET 4.5 (habilitaremos novas imagens de web e work roles com o Windows Server 2012 e NET 4.5 no próximo mês). Fique de olho no meu blog para detalhes assim que esses novos recursos ficarem disponíveis. Espero que ajude, - Scott P.S. Além do blog, eu também estou utilizando o Twitter para atualizações rápidas e para compartilhar links. Siga-me em: twitter.com/ScottGu Texto traduzido do post original por Leniel Macaferi.

  • OTN Developer Days (Review) - San Juan, PR - April 29, 2010

    - by dana.singleterry
    A quick update on the San Juan, PR event. First off it was a great success with the Keynote audience of 200+. Mickey Ralat, Managing Director Oracle Caribbean, kicked off the event with a quick introduction followed by me delivering the Keynote Message - The Fusion Development Platform which is the first session in the regular OTN DD events that we run in North America. Following this session was a partner, SDT, basically marketing their services which covers the Oracle stack and then following was a very brief presentation on APEX. After this we broke out into the various tracks of Java, (APEX) DB SQL Developer, .NET on Oracle. After the breakout we ran the following sessions in the Java track: Developing with JDBC, UCP, and Java in Database, Rich Internet Applications in Web 2.0, Development Made Simple Without Coding: Developing Reusable Business Components. As expected with the various tracks, we ended up with 50 - 70 in the various sessions within the JAVA track and the audience was very impressed with the power of JDeveloper/ADF 11g and we got a number of questions from licensing cost to upgrading / integrating from Forms. As for the Forms questions, I fielded a number of them and for those I couldn't, I pointed them towards Grants resources which seemed to suffice. They were all, for the most part, unaware of the recent 11.1.1.3 release which occurred only a couple of days prior to the event. The indication was that they were going to download it and use it for the lab that was included on the DVD which we did not have the time for them to even start on. For those of you that attended the event, you can download the updated presentations as follows: Keynote - The Fusion Development Platform Rich Internet Applications in Web 2.0 Development Made Simple Without Coding - Developing Reusable Business Components

  • Your Day-by-Day Guide to Agile PLM at Oracle OpenWorld 2012

    - by Kerrie Foy
    This year’s Oracle OpenWorld conference is nearly here, and we’re all excited about what we have planned! With five days of activities and customer presenters from market leaders and top innovators like The Coca-Cola Company, Starbucks, JDSU, Facebook, GlobalFoundries, and more, this is an event you don't want to miss. I've compiled this day-by-day guide to help anyone keep track of all the “Product Lifecycle Management and Product Value Chain” sessions and activities at OpenWorld 2012, September 30 – October 4 in San Francisco, California.  Monday, October 1 There are great networking activities on Sunday September 30, but PLM specific sessions start after general conference keynotes on Monday, October 1 at 10:45 a.m. at the InterContinental Hotel in room Telegraph Hill. In fact, most of our sessions this year will be held in this room, which is still close to the conference keynotes in Moscone, but just far enough away to allow some focused networking and discussions.   This first session, 10:45 – 11:45 a.m. is a joint session with the Agile and AutoVue teams, entitled “Streamline PLM Design-to-Manufacturing Processes with AutoVue Visualization Soltuions” featuring presenters from Oracle as well as joint AutoVue and Agile PLM customer GlobalFoundries. In the following 12:15 – 1:15 p.m. slot, there are two sessions to choose from, so if you have a team of representatives attending OpenWorld, you may consider splitting up to catch both of these: a) Our General Session will be held in the InterContinental Hotel Ballroom C, which will cover our complete enterprise PLM strategy, product updates, and roadmaps. It’s our pleasure to feature a customer keynote presentation from Chris Bedi, CIO, and Rajeev Sethi, Director IT Business Engagement, of JDSU. b) A focused session on integrating PLM with Engineering and Supply Chain Systems will be held on the second floor of Moscone West (next to the InterContinental) in room 2022. Join to discover how these types of integrations help companies manage common and integrated design information across all MCAD, ECAD, and software components. After a lunch break and perhaps a visit to the Demogrounds in Moscone West, select from two product roadmap sessions in the next time slot (3:15 – 4:15 p.m.): an Agile 9.3.x session located in the InterContinental’s Ballroom C, and an Agile PLM for Process session located back in the InterContinental’s Telegraph Room. Both sessions will have strong content around each product line’s latest releases, vision, and customer examples. We are very pleased to feature Daniel Soosai of Facebook in the A9 session and Vinnie D’Agostino of The Coca-Cola Company in the PLM for Process session. Afterwards, hang in there for one last session of the day from 4:45 – 5:45 p.m.; it’s an insightful discussion on leveraging Agile PLM as the Foundation for Enterprise Quality Management, and it’s sure to be one of the best. In the Telegraph Room, this session will feature Oracle experts, partner co-presenter David Bartlett from CPG Solutions, and customer co-presenter Thomas Crowe, CIO of PL Developments. Hear their experience around implementing collaborative, integrated solutions to ensure effective knowledge transfer throughout an organization, and how to perform analysis in real time to resolve product quality issues swiftly and efficiently. On Monday evening there will be plenty of industry, product, and partner dinners, so take advantage of all the networking opportunities and catch some great tunes at the 5 day Oracle OpenWorld Music Festival! Tuesday, October 2 Tuesday starts early with a special PLM Networking Brunch, sponsored by several partners, from 8:30 a.m. – 10:30 a.m. at the B Restaurant that sits atop Yerba Buena Gardens. You’ll have the unique opportunity to meet with like-minded industry peers and a PLM partner to discuss a topic of your choosing while enjoying a delicious meal. Registration is required, so to inquire about attending this brunch, please email Terri.Hiskey-AT-oracle.com. After wrapping up your conversations over brunch, head over to the Marriott Marquis in the Nob Hill CD room for a chance to experience the Oracle Product Lifecycle Analytics solution in a Hands-On Lab, open from 10:15 a.m. – 12:45 p.m. Experts will be there to answer your questions. Back in the InterContinental Hotel’s Telegraph room, the session on “Ideation and Requirements Management: Capturing the Voice of the Customer” begins at 11:45 a.m. – 12:45 p.m. This may be the session for you if you’re struggling with challenges like too many repositories of customer needs, requests, and ideas; limited visibility into which ideas are being advanced by customers and field resources; or if you’re unable to leverage internal expertise to expose effort and potential risks. This session will discuss how Agile PLM can help you overcome ideation challenges to deliver the right products to their targeted markets and fulfill customer desires. Next, from 1:15 – 2:15 p.m. join us for a session on Managing Profitable Innovation with Oracle Product Lifecycle Analytics. If you missed the Hands-on Lab, have more questions, or simply want to be inspired by the product’s forward-thinking vision and capabilities, this is a great opportunity to meet the progressive-minded executives behind the application. After this session, it may be a good opportunity to swing by the Demogrounds in Moscone West and visit the Agile PLM demos at exhibit booths #81 for Agile PLM for Discrete Manufacturing, #70 for Agile PLM for Process, and #82 for AutoVue and Agile PLM Enterprise Visualization. Check out the related Supply Chain Management booths close by if you’re interested - here's the map. There’s always lots to see and do around the exhibit area. But don’t forget the last session of the day from 5:00 p.m. – 6:00 p.m. in Telegraph Hill on Managing Product Innovation and Compliance in Life Science Companies, a “must-see” if you’re in this industry. Launching innovative products quickly is already a high-stakes challenge, but companies in the life sciences industry face uniquely severe consequences when new products don’t perform or comply as required. In recent years, more and more regulations have become mandatory, and new ones, such as REACH, are currently going into effect for several companies. Customer presenters from pharmaceutical leader Eli Lilly will share how they’ve leveraged Agile PLM to deliver high-quality, innovative products in a fast-paced, heavily regulated market environment. Tuesday evening unwind at the Supply Chain Management Reception from 6:00 – 8:00 p.m. at the premier boutique Roe Nightclub and Lounge, which is located about three blocks down on Howard Street (on the other side of Moscone from the InterContinental Hotel). Registration is required. Click here for the details.   Wednesday, October 3 We have another full line-up on Wednesday, so be ready for an action-packed day. We start with a session at 10:15 – 11:15 a.m. in the Telegraph Room where we have a session on “PLM for Consumer Products: Building an Engine for Quality and Innovation” with featured presenters from Starbucks and partner Kalypso. This is a rare opportunity to learn directly from Starbucks how they instill quality and innovation throughout their organization, products, and processes, leveraging PLM disciplines with strong support from their partner.  If you’re not in the consumer products industry, we recommend attending another session at 10:15 – 11:15 a.m. in Moscone West room 3005: “Eco-Enterprise Innovation Awards and the Business Case for Sustainability” featuring Jeff Henley, Oracle’s Chairman of the Board and Jon Chorley, Chief Sustainability Officer. Oracle will honor select customers with Oracle’s Eco-Enterprise Innovation award, which recognizes customers and their respective partners who rely on Oracle products to support their green business practices to reduce their environmental impact while improving business efficiencies and reducing costs. The awards presentation is followed by a panel discussion with customers and Oracle executives, who describe how these award-winning organizations are embracing environmental initiatives as a central part of their business strategy and how information technology plays a pivotal role. Next at 11:45 a.m. – 12:45 p.m. in Telegraph Hill attend our session devoted to exploring Product Lifecycle Management’s role in Software Lifecycle Management. This is a thought leadership session with Oracle experts in the field on the importance of change management, and we’ll discuss how Oracle has for years leveraged Agile PLM to develop Agile PLM. If software lifecycle management doesn’t apply to your business or you’d rather engage in some lively one-on-one discussions, we also have a “Supply Chain Meet the Experts” session in Moscone West Room 2001A. Product experts, thought leaders and executives will be on hand to discuss your questions/topics, so come prepared. This session tends to fill up fast so try to get in early. At 1:15 – 2:15 p.m. join us back in Telegraph Hill for a session focused on leveraging the Agile Product Portfolio Management application as the Product Development Master Schedule to improve efficiencies, optimize resources, and gain visibility across projects enterprise-wide to improve portfolio profitability. Customer presenters from Broadcom will explain how they’ve leveraged the product to enable a master schedule with enterprise-level, phase-gate program and project collaboration and resource optimization. Again in Telegraph Hill from 3:30 – 4:30 p.m. we have an interesting session with leading semiconductor customer LSI and partner Kalypso on how LSI leveraged Agile PLM to advance from homegrown applications to complete Product Value Chain Management. That type of transition can be challenging, and LSI details how they were able to achieve their goals and the value they gained along the journey – a fascinating account for any company interested in leveraging best practices to innovate their business processes and even end products. Lastly, we’ll wrap up in Telegraph Hill from 5:00 – 6:00 p.m. with a session on “Ensuring New Product Success by Achieving Excellence in New Product Introduction.” This is a cross-industry session, guaranteed to deliver insight in the often elusive practice of creating winning products, and we’re very excited about. According to IDC Manufacturing Insights analyst Joe Barkai, “Product Failures are not necessarily a result of bad ideas…they are a result of suboptimal decisions.” We’ll show you how to wire your business processes to enhance decision-making and maximize product potential. Now, quickly hit your hotel room to freshen up and then catch one of the many complimentary shuttles to the much-anticipated Oracle Customer Appreciation Event on Treasure Island. We have a very exciting show planned – check out what’s in store here. Thursday, October 4 PLM has a light schedule on Thursday this year with just one session, but this again is one of our best sessions on managing the Product Value Chain: at 11:15 a.m – 12:15 p.m.in Telegraph Hill, it’s a customer and partner driven session with Sonoco Products and Deloitte telling their story about how to achieve integrated change control by interfacing Agile PLM with Oracle E-Business Suite. Sonoco Products, a global manufacturer of consumer and industrial packaging materials, with its systems integrator, Deloitte, is doing this by implementing prebuilt integration (Oracle Design-to-Release Integration Pack for Agile Product Lifecycle Management for Process and Oracle Process) to integrate Agile with Oracle Product Hub/Oracle Product Information Management and Oracle E-Business Suite. This session presents a case study of how Sonoco is leveraging this solution to improve data quality and build a framework for stronger master data governance. Even though that ends our PLM line-up at OpenWorld, there will still be many sessions and activities at the conference, so visit the Oracle OpenWorld website to review agendas and build your schedule. And of course, download and bring this guide and the latest version of the Agile PLM Focus-On Document (available soon!). San Francisco is a wonderful city to explore, and we’re glad you’re considering joining the Agile PLM team at Oracle OpenWorld!  I hope to see you there! Follow me before the conference and on site for real-time updates about #OOW12 on Twitter @Kerrie_Foy or @AgilePLM.

  • The Making of Arduino [Geek History]

    - by Jason Fitzpatrick
    The open-source Arduino board is the heart of thousands of different DIY projects–it would be easy to think that the Arduino has always been around. The ubiquitous little hobby board, however, is but a scant six years old. At technology blog IEEESpectrum they delve into the history of the Arduino board and its quiet origins in a small Italian town. Here’s an excerpt from their lengthy write up about the the origin and history of the beloved Arduino: Arduino is a low-cost microcontroller board that lets even a novice do really amazing things. You can connect an Arduino to all kinds of sensors, lights, motors, and other devices and use easy-to-learn software to program how your creation will behave. You can build an interactive display or a mobile robot and then share your design with the world by posting it on the Net. Released in 2005 as a modest tool for Banzi’s students at the Interaction Design Institute Ivrea (IDII), Arduino has spawned an international do-it-yourself revolution in electronics. You can buy an Arduino board for just about US $30 or build your own from scratch: All hardware schematics and source code are available for free under public licenses. As a result, Arduino has become the most influential open-source hardware movement of its time. The little board is now the go-to gear for artists, hobbyists, students, and anyone with a gadgetry dream. More than 250 000 Arduino boards have been sold around the world—and that doesn’t include the reams of clones. “It made it possible for people do things they wouldn’t have done otherwise,” says David A. Mellis, who was a student at IDII before pursuing graduate work at the MIT Media Lab and is the lead software developer of Arduino.

  • Caching NHibernate Named Queries

    - by TStewartDev
    I recently started a new job and one of my first tasks was to implement a "popular products" design. The parameters were that it be done with NHibernate and be cached for 24 hours at a time because the query will be pretty taxing and the results do not need to be constantly up to date. This ended up being tougher than it sounds. The database schema meant a minimum of four joins with filtering and ordering criteria. I decided to use a stored procedure rather than letting NHibernate create the SQL for me. Here is a summary of what I learned (even if I didn't ultimately use all of it): You can't, at the time of this writing, use Fluent NHibernate to configure SQL named queries or imports You can return persistent entities from a stored procedure and there are a couple ways to do that You can populate POCOs using the results of a stored procedure, but it isn't quite as obvious You can reuse your named query result mapping other places (avoid duplication) Caching your query results is not at all obvious Testing to see if your cache is working is a pain NHibernate does a lot of things right. Having unified, up-to-date, comprehensive, and easy-to-find documentation is not one of them. By the way, if you're new to this, I'll use the terms "named query" and "stored procedure" (from NHibernate's perspective) fairly interchangeably. Technically, a named query can execute any SQL, not just a stored procedure, and a stored procedure doesn't have to be executed from a named query, but for reusability, it seems to me like the best practice. If you're here, chances are good you're looking for answers to a similar problem. You don't want to read about the path, you just want the result. So, here's how to get this thing going. The Stored Procedure NHibernate has some guidelines when using stored procedures. For Microsoft SQL Server, you have to return a result set. The scalar value that the stored procedure returns is ignored as are any result sets after the first. Other than that, it's nothing special. CREATE PROCEDURE GetPopularProducts @StartDate DATETIME, @MaxResults INT AS BEGIN SELECT [ProductId], [ProductName], [ImageUrl] FROM SomeTableWithJoinsEtc END The Result Class - PopularProduct You have two options to transport your query results to your view (or wherever is the final destination): you can populate an existing mapped entity class in your model, or you can create a new entity class. If you go with the existing model, the advantage is that the query will act as a loader and you'll get full proxied access to the domain model. However, this can be a disadvantage if you require access to the related entities that aren't loaded by your results. For example, my PopularProduct has image references. Unless I tie them into the query (thus making it even more complicated and expensive to run), they'll have to be loaded on access, requiring more trips to the database. Since we're trying to avoid trips to the database by using a second-level cache, we should use the second option, which is to create a separate entity for results. This approach is (I believe) in the spirit of the Command-Query Separation principle, and it allows us to flatten our data and optimize our report-generation process from data source to view. public class PopularProduct { public virtual int ProductId { get; set; } public virtual string ProductName { get; set; } public virtual string ImageUrl { get; set; } } The NHibernate Mappings (hbm) Next up, we need to let NHibernate know about the query and where the results will go. Below is the markup for the PopularProduct class. Notice that I'm using the <resultset> element and that it has a name attribute. The name allows us to drop this into our query map and any others, giving us reusability. Also notice the <import> element which lets NHibernate know about our entity class. <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <import class="PopularProduct, Infrastructure.NHibernate, Version=1.0.0.0"/> <resultset name="PopularProductResultSet"> <return-scalar column="ProductId" type="System.Int32"/> <return-scalar column="ProductName" type="System.String"/> <return-scalar column="ImageUrl" type="System.String"/> </resultset> </hibernate-mapping>  And now the PopularProductsMap: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <sql-query name="GetPopularProducts" resultset-ref="PopularProductResultSet" cacheable="true" cache-mode="normal"> <query-param name="StartDate" type="System.DateTime" /> <query-param name="MaxResults" type="System.Int32" /> exec GetPopularProducts @StartDate = :StartDate, @MaxResults = :MaxResults </sql-query> </hibernate-mapping>  The two most important things to notice here are the resultset-ref attribute, which links in our resultset mapping, and the cacheable attribute. The Query Class – PopularProductsQuery So far, this has been fairly obvious if you're familiar with NHibernate. This next part, maybe not so much. You can implement your query however you want to; for me, I wanted a self-encapsulated Query class, so here's what it looks like: public class PopularProductsQuery : IPopularProductsQuery { private static readonly IResultTransformer ResultTransformer; private readonly ISessionBuilder _sessionBuilder;   static PopularProductsQuery() { ResultTransformer = Transformers.AliasToBean<PopularProduct>(); }   public PopularProductsQuery(ISessionBuilder sessionBuilder) { _sessionBuilder = sessionBuilder; }   public IList<PopularProduct> GetPopularProducts(DateTime startDate, int maxResults) { var session = _sessionBuilder.GetSession(); var popularProducts = session .GetNamedQuery("GetPopularProducts") .SetCacheable(true) .SetCacheRegion("PopularProductsCacheRegion") .SetCacheMode(CacheMode.Normal) .SetReadOnly(true) .SetResultTransformer(ResultTransformer) .SetParameter("StartDate", startDate.Date) .SetParameter("MaxResults", maxResults) .List<PopularProduct>();   return popularProducts; } }  Okay, so let's look at each line of the query execution. The first, GetNamedQuery, matches up with our NHibernate mapping for the sql-query. Next, we set it as cacheable (this is probably redundant since our mapping also specified it, but it can't hurt, right?). Then we set the cache region which we'll get to in the next section. Set the cache mode (optional, I believe), and my cache is read-only, so I set that as well. The result transformer is very important. This tells NHibernate how to transform your query results into a non-persistent entity. You can see I've defined ResultTransformer in the static constructor using the AliasToBean transformer. The name is obviously leftover from Java/Hibernate. Finally, set your parameters and then call a result method which will execute the query. Because this is set to cached, you execute this statement every time you run the query and NHibernate will know based on your parameters whether to use its cached version or a fresh version. The Configuration – hibernate.cfg.xml and Web.config You need to explicitly enable second-level caching in your hibernate configuration: <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> [...] <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property> <property name="cache.provider_class">NHibernate.Caches.SysCache.SysCacheProvider,NHibernate.Caches.SysCache</property> <property name="cache.use_query_cache">true</property> <property name="cache.use_second_level_cache">true</property> [...] </session-factory> </hibernate-configuration> Both properties "use_query_cache" and "use_second_level_cache" are necessary. As this is for a web deployement, we're using SysCache which relies on ASP.NET's caching. Be aware of this if you're not deploying to the web! You'll have to use a different cache provider. We also need to tell our cache provider (in this cache, SysCache) about our caching region: <syscache> <cache region="PopularProductsCacheRegion" expiration="86400" priority="5" /> </syscache> Here I've set the cache to be valid for 24 hours. This XML snippet goes in your Web.config (or in a separate file referenced by Web.config, which helps keep things tidy). The Payoff That should be it! At this point, your queries should run once against the database for a given set of parameters and then use the cache thereafter until it expires. You can, of course, adjust settings to work in your particular environment. Testing Testing your application to ensure it is using the cache is a pain, but if you're like me, you want to know that it's actually working. It's a bit involved, though, so I'll create a separate post for it if comments indicate there is interest.

  • Java Champion Jim Weaver on JavaFX

    - by Janice J. Heiss
    Hardly anyone knows more about JavaFX than Java Champion and Oracle’s JavaFX Evangelist, Jim Weaver, who will be leading two Hands on Labs on aspects of JavaFX at this year’s JavaOne: HOL11265 – “Playing to the Strengths of JavaFX and HTML5” (With Jeff Klamer - App Designer, Jeff Klamer Design) Wednesday, Oct 3, 3:00 PM - 5:00 PM - Hilton San Francisco - Franciscan A/B/C/D HOL3058 – “Custom JavaFX Controls” (With Gerrit Grunwald, Senior Software Engineer, Canoo Engineering AG; Bob Larsen, Consultant, Larsen Consulting; and Peter Vašenda, Software Engineer, Oracle) Tuesday, Oct 2, 12:30 PM - 2:30 PM - Hilton San Francisco - Franciscan A/B/C/D I caught up with Jim at JavaOne to ask him for a current snapshot of JavaFX. “In my opinion,” observed Weaver, “the most important thing happening with JavaFX is the ongoing improvement to rich-client Java application deployment. For example, JavaFX packaging tools now provide built-in support for self-contained application packages. A package may optionally contain the Java Runtime, and be distributed with a native installer (e.g., a DMG or EXE). This makes it easy for users to install JavaFX apps on their client machines, perhaps obtaining the apps from the Mac App Store, for example. Igor Nekrestyanov and Nancy Hildebrandt have written a comprehensive guide to JavaFX application deployment, the following section of which covers Self-Contained Application Packaging: http://docs.oracle.com/javafx/2/deployment/self-contained-packaging.htm#BCGIBBCI.“Igor also wrote a blog post titled, "7u10: JavaFX Packaging Tools Update," that covers improvements introduced so far in Java SE 7 update 10. Here's the URL to the blog post:https://blogs.oracle.com/talkingjavadeployment/entry/packaging_improvements_in_jdk_7”I asked about how the strengths of JavaFX and HTML5 interact and reinforce each other. “They interact and reinforce each other very well. I was about to be amazed at your insight in asking that question, but then recalled that one of my JavaOne sessions is a Hands-on Lab titled ‘Playing to the Strengths of JavaFX and HTML5.’ In that session, we'll cover the JavaFX and HTML5 WebView control, the strengths of each technology, and the various ways that Java and contents of the WebView can interact.”And what is he looking forward to at JavaOne? “I'm personally looking forward to some excellent sessions, and connecting with colleagues and friends that I haven't seen in a while!” Jim Weaver is another good reason to feel good about JavaOne.
