• Best way to integrate StyleCop with TFS CI

  - by Slavo

  I've been doing research on how to enable source analysis for the project I'm working on and plan to use StyleCop. The setup I have is a TFS Server for source control, using TFS Continuous Integration. I want to enable source analysis for CI builds and daily builds run on the build machine, and not only for those run on developers' machines. Here's an article from the documentation of StyleCop that I read on the subject: http://blog.newagesolution.net/2008/07/how-to-use-stylecop-and-msbuild-and.html. It basically modifies the csproj file for the purpose. I've also read other opinions about how StyleCop should be integrated with build automation, which advise doing the same thing using build tasks: http://blog.newagesolution.net/2008/07/how-to-use-stylecop-and-msbuild-and.html http://freetodev.spaces.live.com/blog/cns!EC3C8F2028D842D5!400.entry. What are you opinions? Have you had similar projects and done something like this?

• Config transformations and “TransformXml task failed” error message

  - by Troy Hunt

  I’ve just enabled config transformations on a .NET 3.5 project in VS2010 RC after watching Scott Hanselman’s video on web deployment. Unfortunately every time I go to publish I now get the following error: The "TransformXml" task failed unexpectedly. System.UriFormatException: Invalid URI: The URI is empty. at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind) at System.Uri..ctor(String uriString) at Microsoft.Web.Publishing.Tasks.TransformXml.Execute() at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute() at Microsoft.Build.BackEnd.TaskBuilder.ExecuteInstantiatedTask(ITaskExecutionHost taskExecutionHost, TaskLoggingContext taskLoggingContext, TaskHost taskHost, ItemBucket bucket, TaskExecutionMode howToExecuteTask, Boolean& taskResult) If I take a brand new VS2010 web application which already has the config transformations by default I don’t have a problem so I suspect my issue is project related. Has anyone come across this before or have any ideas on a fix?

• How to debug a Flex 4 HTTPService request that works on my computer, but not on another?

  - by ben

  I'm building a Ruby on Rails backed Flex 4 app, using Heroku to host the Ruby on Rails part during development. It all works fine when I run the release build on my computer, but when I run the release build on a friends computer, the data from the database doesn't get loaded. Problem is, I can't work out how to debug this because it's the release build, and I've only got Flash Builder 4 on my computer, where it all works fine. How can I go about trying to solve this problem? Thanks for reading.

• How to run assembly using NUnit's TestSuiteBuilder

  - by Dror Helper

  I'm trying to write a simple method that receives a file an runs it using NUnit. The code I managed to build using NUnit's source does not work: if(openFileDialog1.ShowDialog() != DialogResult.OK) { return; } var builder = new TestSuiteBuilder(); var testPackage = new TestPackage(openFileDialog1.FileName); var directoryName = Path.GetDirectoryName(openFileDialog1.FileName); testPackage.BasePath = directoryName; var suite = builder.Build(testPackage); TestResult result = suite.Run(new NullListener(), TestFilter.Empty); The problem is that I keep getting an exception thrown by builder.Build stating that the assembly was not found. What am I missing?

• Python issue:Unable to find vcvarsall.bat

  I'm trying to install MySql interface for python,but I got an error(mentioned below).And I know the solution,install the Microsoft Visual C++.So what my question is there any alternative solution apart from installing Microsoft Visual C++,I mean it's really hurt me,why should I install Microsoft Visual C++ just because to build this single package it's a useless and time wasting approach from the developers perspective.So I kindly request from all of you please mention if you have any alternative solution for this issue.

• F# PowerPack 2.0.0.0 issue: The task ..."…\fslex.exe" is invalid

  - by Roman Kuzmin

  I have upgraded F# PowerPack today to the latest 2.0.0.0 and tried to rebuild the MiniCalc sample from here: http://achrissmith.blogspot.com/2010/04/fslex-and-fsyacc-examples-updated.html If I build it in VS 2010 it fails with the message: C:\Program Files\MSBuild\FSharp\1.0\FSharp.PowerPack.targets(32,3): error MSB6004: The specified task executable location "C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\fslex.exe" is invalid. If I build it from the command line by MSBuild it complains about missing C:\Windows\Microsoft.NET\Framework\v4.0.30319\fslex.exe The problem is kind of “fixed” if I copy fslex and fsyacc to that both directories, so after that I can build from the command line and from VS 2010. But it does not look like a right way to solve the problem. What is the right way? EDIT: The same issue is true for the PowerPack sample from sources: May2010\workyard\tests\LexAndYaccMiniProject. Now (after the trick I have done) it is built fine, too.

• How to manage memory using classes in Objective-C?

  - by Flipper

  This is my first time creating an iPhone App and I am having difficulty with the memory management because I have never had to deal with it before. I have a UITableViewController and it all works fine until I try to scroll down in the simulator. It crashes saying that it cannot allocate that much memory. I have narrowed it down to where the crash is occurring: - (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // Dequeue or create a cell UITableViewCellStyle style = UITableViewCellStyleDefault; UITableViewCell *cell = [aTableView dequeueReusableCellWithIdentifier:@"BaseCell"]; if (!cell) cell = [[[UITableViewCell alloc] initWithStyle:style reuseIdentifier:@"BaseCell"] autorelease]; NSString* crayon; // Retrieve the crayon and its color if (aTableView == self.tableView) { crayon = [[[self.sectionArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row] getName]; } else { crayon = [FILTEREDKEYS objectAtIndex:indexPath.row]; } cell.textLabel.text = crayon; if (![crayon hasPrefix:@"White"]) cell.textLabel.textColor = [self.crayonColors objectForKey:crayon]; else cell.textLabel.textColor = [UIColor blackColor]; return cell; } Here is the getName method: - (NSString*)getName { return name; } name is defined as: @property (nonatomic, retain) NSString *name; Now sectionArray is an NSMutableArray with instances of a class that I created Term in it. Term has a method getName that returns a NSString*. The problem seems to be the part of where crayon is being set and getName is being called. I have tried adding autorelease, release, and other stuff like that but that just causes the entire app to crash before even launching. Also if I do: cell.textLabel.text = @"test"; //crayon; /*if (![crayon hasPrefix:@"White"]) cell.textLabel.textColor = [self.crayonColors objectForKey:crayon]; else cell.textLabel.textColor = [UIColor blackColor];*/ Then I get no error whatsoever and it all scrolls just fine. Thanks in advance for the help! Edit: Here is the full Log of when I try to run the app and the error it gives when it crashes: [Session started at 2010-12-29 04:23:38 -0500.] [Session started at 2010-12-29 04:23:44 -0500.] GNU gdb 6.3.50-20050815 (Apple version gdb-967) (Tue Jul 14 02:11:58 UTC 2009) Copyright 2004 Free Software Foundation, Inc.

• Enumerating .NET assembly resources at runtime

  - by Alex_P

  I have a resource assembly with image files in it that are built using Resource or Content build action. This makes these files accessible using the Uris. However I cannot find the way to enumerate such resources. If I set the build action to Embedded Resource it becomes possible to enumerate the files with the following code: string[] resources = Assembly.GetExecutingAssembly().GetManifestResourceNames(); but it in turn makes these files inaccessible using Uris. The question is - how to enumerate resources that are compiled with either Resource or Content build action? NOTE: As Thomas Levesque pointed out it is possible to enumerate such resources by leveraging the AssemblyAssociatedContentFileAttribute, but it seems to only work for WPF Application assemblies and not for class library ones. So the question is still open.

• How do i compile a static library (fat) for armv6, armv7 and i386

  - by unforgiven

  I know this question has been posed several times, but my goal is slightly different with regard to what I have found searching the web. Specifically, I am already able to build a static library for iPhone, but the final fat file I am able to build only contains arm and i386 architectures (and I am not sure to what arm refers: is v6 or v7?). I am not able to compile specifically for armv6 and armv7 and them merge both architectures using lipo. The lipo tool complains that the same architecture (arm, not armv6 or armv7) is present in both the armv6 and armv7 libraries. Can someone explain exactly how to build for armv6 and armv7, and them merge these libraries into a fat file using lipo?

• Upgrading Visual Studio 2010 RC to RTM

  - by Brant Bobby

  I have the RC build of VS2010 installed on my computer. Now that the RTM build is out, I want to upgrade. Aside from the main Visual Studio package and .NET Framework 4, what else should I remove before I install the RTM build in order to minimize potential breakage/conflicts? VS2010 installs a whole bunch of ancillary packages and I'm not sure which ones have been upgraded between RC and RTM. (Extra credit: I've got another machine that is still running Beta 2. Would the procedure be the same?)

• How to bootstrap NAnt environment from an existing solution (.sln)

  - by Ron Harlev

  I have a Visual Studio 2005 solution (.sln) with a mix of .NET and C++ projects. What is the best way to generate the .build file I will need to run my build process with NAnt. I'm new to using NAnt, and I'm not sure how to set it up. Will I have to update the .build file manually every time there is a new source file in any of the projects? Is there a tool that will generate the files for NAnt from the .sln and studio project files?

• error executing aapt, all of the sudden

  - by pjv

  I know there are a lot of these topics around but none seem to help in my case, nor describe it exactly. The best similar one is aapt not found under the right path. My problem is that I can be using Eclipse for a whole evening programming, compiling and using my device, and then suddenly I get "error executing aapt" for my current project and ofcourse R.java isn't (properly) generated anymore. I then restart Eclipse and everything goes away. I'm seeing this once a day on average however. I've recently switched to amd64 and installed the latest Android-2.3 SDK and matching tools. I know that there is now a platform-tools folder that has an aapt version that should work SDK version independently. At first I had added this directory to my PATH, as instructed on the SDK website. I've also tried not adding it to my path and making a link platforms/android-9/tools so that every SDK version might use it's own old copy. Needless to say, platform-tools/aapt is there and has the right permissions, and I have been able to execute it on the command-line at any time. When I do write a faulty xml file or sorts, and appropriately get an error, I see an extra line that says "aapt: /lib32/libz.so.1: no version information available". I'm running a recent Gentoo linux system. I have everything installed to support x86 on amd64, but have re-emerged emul-linux-x86-baselibs and zlib just to be sure. The problem persists. I do see some pages that spell horror over some zlib bugs, but I'm not sure if that's related. I realize I'm not on the reference Ubuntu platform, but surely the difference cannot be that great? It might very well be a bug in aapt or the tools itself. Why would it suddenly stop working? I also experience that the ids in R.java were incorrect, namely that simple findViewById() code would give ClassCastExceptions because of mixed ids the one time, and then work perfectly without any changes bu only a "clean project", in the aftermath of a failing aapt. Finally, I've run a few commands on aapt, that don't seem to add any extra information: #ldd aapt ./aapt: /lib32/libz.so.1: no version information available (required by ./aapt) linux-gate.so.1 => (0xffffe000) librt.so.1 => /lib32/librt.so.1 (0x4f864000) libpthread.so.0 => /lib32/libpthread.so.0 (0x4f849000) libz.so.1 => /lib32/libz.so.1 (0xf7707000) libstdc++.so.6 => /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.4/32/libstdc++.so.6 (0x415e9000) libm.so.6 => /lib32/libm.so.6 (0x4f876000) libgcc_s.so.1 => /lib32/libgcc_s.so.1 (0x4fac6000) libc.so.6 => /lib32/libc.so.6 (0x4f5ed000) /lib/ld-linux.so.2 (0x4f5ca000) #file aapt aapt: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped Can anybody tell anything wrong with my configuration? Does it smell like a bug perhaps (otherwise let's report it (again))? Update 2010-01-06: I've gained some more knowledge. When I recently was trying to export a signed apk, I ran into another error message (full details from the Eclipse error view) regarding aapt I hadn't seen before. Note here too, that I can just restart Eclipse and can export apks again without problems, at least for a little while. I'm starting to think it is related to lack of memory on my system. The message "onvoldoende geheugen beschikbaar" means "insufficient memory available". I have also been seeing insufficient memory errors in DDMS when I'm dumping HPROF files. Here is the error log (shortened): !ENTRY com.android.ide.eclipse.adt 4 0 2011-01-05 23:11:16.097 !MESSAGE Export Wizard Error !STACK 1 org.eclipse.core.runtime.CoreException: Failed to export application at com.android.ide.eclipse.adt.internal.project.ExportHelper.exportReleaseApk(Unknown Source) at com.android.ide.eclipse.adt.internal.wizards.export.ExportWizard.doExport(Unknown Source) at com.android.ide.eclipse.adt.internal.wizards.export.ExportWizard.access$0(Unknown Source) at com.android.ide.eclipse.adt.internal.wizards.export.ExportWizard$1.run(Unknown Source) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121) Caused by: com.android.ide.eclipse.adt.internal.build.AaptExecException: Error executing aapt.

• vs 2010 Deployment without Web Deploy

  - by dritterweg

  with vs 2008 I always used Web Deployment Project to build to three different environments. It is maybe not the best solution, since I still have to xcopy the built files to the server, but it is simple. now with vs 2010 it looks promising, but It looks also complicated. My hosting doesn't have Web Deploy, the newest feature and the flagship technology for deployment in vs2010. My question how can I just build for each environment and copy the files over to the server. Using the Build Deployment Package will create the zip file and when I extract it, it will output so many files and confusing folder structure. Anyone has suggestion?

• Why is MonoDevelop compiling with csc.exe?

  - by korchev

  I am trying to use MonoDevelop (2.4 beta 1) on Windows (7 x64) in order to test a .NET application on Mono (2.6.4). For some reason MonoDevelop is not using the Mono tool chain to build the application. It compiles it with the Microsoft tool chain - C:\Windows\Microsoft.NET\Framework\v3.5\csc.exe. The project I am trying to build is a simple ASP.NET MVC application generated from the "New ASP.NET MVC application" template. The "Runtime Version" dropdown in Project \Options-Build-General shows "MONO/.NET 35". What gives? Is there a way to change the .NET tool chain?

• Can we generate multiple coverage reports using Hudson Emma plugin

  - by Subhashish

  We run both unit (junit) and system (fit) tests on instrumented code in our build. The consolidated coverage report for both is generated as part of the build itself. We then feed the unit test coverage report to the Hudson Emma plugin, configure benchmark numbers and things work nicely. Is it possible to also feed in the system test coverage report separately to the same plugin so that we can get that report and configure benchmarks for that as well? I know there is a workaround of creating a downstream project for the latter activity but it would be good to be able to do both in the same build.

• Class member functions instantiated by traits

  - by Jive Dadson

  I am reluctant to say I can't figure this out, but I can't figure this out. I've googled and searched Stack Overflow, and come up empty. The abstract, and possibly overly vague form of the question is, how can I use the traits-pattern to instantiate non-virtual member functions? The question came up while modernizing a set of multivariate function optimizers that I wrote more than 10 years ago. The optimizers all operate by selecting a straight-line path through the parameter space away from the current best point (the "update"), then finding a better point on that line (the "line search"), then testing for the "done" condition, and if not done, iterating. There are different methods for doing the update, the line-search, and conceivably for the done test, and other things. Mix and match. Different update formulae require different state-variable data. For example, the LMQN update requires a vector, and the BFGS update requires a matrix. If evaluating gradients is cheap, the line-search should do so. If not, it should use function evaluations only. Some methods require more accurate line-searches than others. Those are just some examples. The original version instantiates several of the combinations by means of virtual functions. Some traits are selected by setting mode bits that are tested at runtime. Yuck. It would be trivial to define the traits with #define's and the member functions with #ifdef's and macros. But that's so twenty years ago. It bugs me that I cannot figure out a whiz-bang modern way. If there were only one trait that varied, I could use the curiously recurring template pattern. But I see no way to extend that to arbitrary combinations of traits. I tried doing it using boost::enable_if, etc.. The specialized state information was easy. I managed to get the functions done, but only by resorting to non-friend external functions that have the this-pointer as a parameter. I never even figured out how to make the functions friends, much less member functions. The compiler (VC++ 2008) always complained that things didn't match. I would yell, "SFINAE, you moron!" but the moron is probably me. Perhaps tag-dispatch is the key. I haven't gotten very deeply into that. Surely it's possible, right? If so, what is best practice? UPDATE: Here's another try at explaining it. I want the user to be able to fill out an order (manifest) for a custom optimizer, something like ordering off of a Chinese menu - one from column A, one from column B, etc.. Waiter, from column A (updaters), I'll have the BFGS update with Cholesky-decompositon sauce. From column B (line-searchers), I'll have the cubic interpolation line-search with an eta of 0.4 and a rho of 1e-4, please. Etc... UPDATE: Okay, okay. Here's the playing-around that I've done. I offer it reluctantly, because I suspect it's a completely wrong-headed approach. It runs okay under vc++ 2008. #include <boost/utility.hpp> #include <boost/type_traits/integral_constant.hpp> namespace dj { struct CBFGS { void bar() {printf("CBFGS::bar %d\n", data);} CBFGS(): data(1234){} int data; }; template<class T> struct is_CBFGS: boost::false_type{}; template<> struct is_CBFGS<CBFGS>: boost::true_type{}; struct LMQN {LMQN(): data(54.321){} void bar() {printf("LMQN::bar %lf\n", data);} double data; }; template<class T> struct is_LMQN: boost::false_type{}; template<> struct is_LMQN<LMQN> : boost::true_type{}; struct default_optimizer_traits { typedef CBFGS update_type; }; template<class traits> class Optimizer; template<class traits> void foo(typename boost::enable_if<is_LMQN<typename traits::update_type>, Optimizer<traits> >::type& self) { printf(" LMQN %lf\n", self.data); } template<class traits> void foo(typename boost::enable_if<is_CBFGS<typename traits::update_type>, Optimizer<traits> >::type& self) { printf("CBFGS %d\n", self.data); } template<class traits = default_optimizer_traits> class Optimizer{ friend typename traits::update_type; //friend void dj::foo<traits>(typename Optimizer<traits> & self); // How? public: //void foo(void); // How??? void foo() { dj::foo<traits>(*this); } void bar() { data.bar(); } //protected: // How? typedef typename traits::update_type update_type; update_type data; }; } // namespace dj int main_() { dj::Optimizer<> opt; opt.foo(); opt.bar(); std::getchar(); return 0; }

• LLVM: bitcode with llvm-gcc (mingw) for windows

  - by TheShow

  Hi, i'm currently building a small JIT compiler. For the language I need a runtime library for some special math functions. I think the best would be to compile the lib to bitcode and link it. The compiler should be integrated in a product and as of this, it must work under windows (VC10, 64bit). So is it possible to build the math lib with the mingw llvm-gcc build an link it later with the JITed Code? Or are there any problems regarding the portability of the bitcode build with llvm-gcc under mingw? If there are problems, what solution would you suggest?

• Software to create a knowledge base/FAQ system

  - by H1Man

  Our company is looking to build a web-based knowledge base system that can be used by our clients/end users to reduce the amount of support calls. Couple important notes: This is aimed at our end users, in other words, non-techies. So the UI has to be easy to use Should have the excellent (fast, accurate) search Should have ability to rate and comment on articles This will only be maintained by one or 2 people, so security isn't a big concern Something similar to what Microsoft is doing with their Knowledge Base. http://support.microsoft.com/search/ Does anyone have any recommendations on what software I can use? Thanks, H. Edit: I should have made this clear before but I don't mean build as in having our developers build a support/kb system from the ground up. I am looking to use a existing software package/solution that can be used to implement a knowledge base/support site.

• Recap: Oracle Fusion Middleware Strategies Driving Business Innovation

  - by Harish Gaur

  Hasan Rizvi, Executive Vice President of Oracle Fusion Middleware & Java took the stage on Tuesday to discuss how Oracle Fusion Middleware helps enable business innovation. Through a series of product demos and customer showcases, Hassan demonstrated how Oracle Fusion Middleware is a complete platform to harness the latest technological innovations (cloud, mobile, social and Fast Data) throughout the application lifecycle. Fig 1: Oracle Fusion Middleware is the foundation of business innovation This Session included 4 demonstrations to illustrate these strategies: 1. Build and deploy native mobile applications using Oracle ADF Mobile 2. Empower business user to model processes, design user interface and have rich mobile experience for process interaction using Oracle BPM Suite PS6. 3. Create collaborative user experience and integrate social sign-on using Oracle WebCenter Portal, Oracle WebCenter Content, Oracle Social Network & Oracle Identity Management 11g R2 4. Deploy and manage business applications on Oracle Exalogic Nike, LA Department of Water & Power and Nintendo joined Hasan on stage to share how their organizations are leveraging Oracle Fusion Middleware to enable business innovation. Managing Performance in the Wrld of Social and Mobile How do you provide predictable scalability and performance for an application that monitors active lifestyle of 8 million users on a daily basis? Nike’s answer is Oracle Coherence, a component of Oracle Fusion Middleware and Oracle Exadata. Fig 2: Oracle Coherence enabled data grid improves performance of Nike+ Digital Sports Platform Nicole Otto, Sr. Director of Consumer Digital Technology discussed the vision of the Nike+ platform, a platform which represents a shift for NIKE from a  "product"  to  a "product +" experience.  There are currently nearly 8 million users in the Nike+ system who are using digitally-enabled Nike+ devices.  Once data from the Nike+ device is transmitted to Nike+ application, users access the Nike+ website or via the Nike mobile applicatoin, seeing metrics around their daily active lifestyle and even engage in socially compelling experiences to compare, compete or collaborate their data with their friends. Nike expects the number of users to grow significantly this year which will drive an explosion of data and potential new experiences. To deal with this challenge, Nike envisioned building a shared platform that would drive a consumer-centric model for the company. Nike built this new platform using Oracle Coherence and Oracle Exadata. Using Coherence, Nike built a data grid tier as a distributed cache, thereby provide low-latency access to most recent and relevant data to consumers. Nicole discussed how Nike+ Digital Sports Platform is unique in the way that it utilizes the Coherence Grid.  Nike takes advantage of Coherence as a traditional cache using both cache-aside and cache-through patterns.  This new tier has enabled Nike to create a horizontally scalable distributed event-driven processing architecture. Current data grid volume is approximately 150,000 request per minute with about 40 million objects at any given time on the grid. Improving Customer Experience Across Multiple Channels Customer experience is on top of every CIO's mind. Customer Experience needs to be consistent and secure across multiple devices consumers may use.  This is the challenge Matt Lampe, CIO of Los Angeles Department of Water & Power (LADWP) was faced with. Despite being the largest utilities company in the country, LADWP had been relying on a 38 year old customer information system for serving its customers. Their prior system  had been unable to keep up with growing customer demands. Last year, LADWP embarked on a journey to improve customer experience for 1.6million LA DWP customers using Oracle WebCenter platform. Figure 3: Multi channel & Multi lingual LADWP.com built using Oracle WebCenter & Oracle Identity Management platform Matt shed light on his efforts to drive customer self-service across 3 dimensions – new website, new IVR platform and new bill payment service. LADWP has built a new portal to increase customer self-service while reducing the transactions via IVR. LADWP's website is powered Oracle WebCenter Portal and is accessible by desktop and mobile devices. By leveraging Oracle WebCenter, LADWP eliminated the need to build, format, and maintain individual mobile applications or websites for different devices. Their entire content is managed using Oracle WebCenter Content and secured using Oracle Identity Management. This new portal automated their paper based processes to web based workflows for customers. This includes automation of Self Service implemented through My Account -  like Bill Pay, Payment History, Bill History and Usage Analysis. LADWP's solution went live in April 2012. Matt indicated that LADWP's Self-Service Portal has greatly improved customer satisfaction.  In a JD Power Associates website satisfaction survey, results indicate rankings have climbed by 25+ points, marking a remarkable increase in user experience. Bolstering Performance and Simplifying Manageability of Business Applications Ingvar Petursson, Senior Vice Preisdent of IT at Nintendo America joined Hasan on-stage to discuss their choice of Exalogic. Nintendo had significant new requirements coming their way for business systems, both internal and external, in the years to come, especially with new products like the WiiU on the horizon this holiday season. Nintendo needed a platform that could give them performance, availability and ease of management as they deploy business systems. Ingvar selected Engineered Systems for two reasons: 1. High performance  2. Ease of management Figure 4: Nintendo relies on Oracle Exalogic to run ATG eCommerce, Oracle e-Business Suite and several business applications Nintendo made a decision to run their business applications (ATG eCommerce, E-Business Suite) and several Fusion Middleware components on the Exalogic platform. What impressed Ingvar was the "stress” testing results during evaluation. Oracle Exalogic could handle their 3-year load estimates for many functions, which was better than Nintendo expected without any hardware expansion. Faster Processing of Big Data Middleware plays an increasingly important role in Big Data. Last year, we announced at OpenWorld the introduction of Oracle Data Integrator for Hadoop and Oracle Loader for Hadoop which helps in the ability to move, transform, load data to and from Big Data Appliance to Exadata.  This year, we’ve added new capabilities to find, filter, and focus data using Oracle Event Processing. This product can natively integrate with Big Data Appliance or runs standalone. Hasan briefly discussed how NTT Docomo, largest mobile operator in Japan, leverages Oracle Event Processing & Oracle Coherence to process mobile data (from 13 million smartphone users) at a speed of 700K events per second before feeding it Hadoop for distributed processing of big data. Figure 5: Mobile traffic data processing at NTT Docomo with Oracle Event Processing & Oracle Coherence

  I'm using Python 2.6 and cx_Freeze 4.1.2 on a Windows system. I've created the setup.py to build my executable and everything works fine. When cx_Freeze runs it movies everything to the build directory. I have some other files that i would like included in my build directory. How can i do this? Here's my structure. src\ setup.py janitor.py README.txt CHNAGELOG.txt helpers\ uncompress\ unRAR.exe unzip.exe Here's my snippet: setup ( name='Janitor', version='1.0', description='Janitor', author='John Doe', author_email='[email protected]', url='http://www.this-page-intentionally-left-blank.org/', data_files = [ ('helpers\uncompress', ['helpers\uncompress\unzip.exe']), ('helpers\uncompress', ['helpers\uncompress\unRAR.exe']), ('', ['README.txt']) ], executables = [ Executable\ ( 'janitor.py', #initScript ) ] ) I can't seem to get this to work. Do i need a MANIFEST.in file? Thank you.
