  • Wrong perspective is showing in Eclipse plugin project [closed]

    - by Arun Kumar Choudhary
    I am working in Eclipse Modeling Framework (Eclipse plugin development) in my project the tool(project i am working) provides three perspectives. 1.Accelerator Analyst perspective 2.Contract Validation and 3.Underwriter rules Editor... By default it starts with Contract validation perspective (As we define it within the plugin_customization.ini). However after switching to other perspective does not change the perspective shown... As all perspective (Class, Id and Name) is define only inside Plugin.XML as it is the task of org.eclipse.ui.perspective that that perspective name should be come forefront. Out of 10 7 times it is working fine but I am not getting why this is not working in that 3 cases. I am pasting my plugin.XML file <?xml version="1.0" encoding="UTF-8"?> <?eclipse version="3.0"?> <plugin> <extension id="RuleEditor.application" name="Accelerator Tooling"

  • Q&A: Oracle's Paul Needham on How to Defend Against Insider Attacks

    - by Troy Kitch
    Source: Database Insider Newsletter: The threat from insider attacks continues to grow. In fact, just since January 1, 2014, insider breaches have been reported by a major consumer bank, a major healthcare organization, and a range of state and local agencies, according to the Privacy Rights Clearinghouse.  We asked Paul Needham, Oracle senior director, product management, to shed light on the nature of these pernicious risks—and how organizations can best defend themselves against the threat from insider risks. Q. First, can you please define the term "insider" in this context? A. According to the CERT Insider Threat Center, a malicious insider is a current or former employee, contractor, or business partner who "has or had authorized access to an organization's network, system, or data and intentionally exceeded or misused that access in a manner that negatively affected the confidentiality, integrity, or availability of the organization's information or information systems."  Q. What has changed with regard to insider risks? A. We are actually seeing the risk of privileged insiders growing. In the latest Independent Oracle Users Group Data Security Survey, the number of organizations that had not taken steps to prevent privileged user access to sensitive information had grown from 37 percent to 42 percent. Additionally, 63 percent of respondents say that insider attacks represent a medium-to-high risk—higher than any other category except human error (by an insider, I might add). Q. What are the dangers of this type of risk? A. Insiders tend to have special insight and access into the kinds of data that are especially sensitive. Breaches can result in long-term legal issues and financial penalties. They can also damage an organization's brand in a way that directly impacts its bottom line. Finally, there is the potential loss of intellectual property, which can have serious long-term consequences because of the loss of market advantage.  Q. How can organizations protect themselves against abuse of privileged access? A. Every organization has privileged users and that will always be the case. The questions are how much access should those users have to application data stored in the database, and how can that default access be controlled? Oracle Database Vault (See image) was designed specifically for this purpose and helps protect application data against unauthorized access.  Oracle Database Vault can be used to block default privileged user access from inside the database, as well as increase security controls on the application itself. Attacks can and do come from inside the organization, and they are just as likely to come from outside as attempts to exploit a privileged account.  Using Oracle Database Vault protection, boundaries can be placed around database schemas, objects, and roles, preventing privileged account access from being exploited by hackers and insiders.  A new Oracle Database Vault capability called privilege analysis identifies privileges and roles used at runtime, which can then be audited or revoked by the security administrators to reduce the attack surface and increase the security of applications overall.  For a more comprehensive look at controlling data access and restricting privileged data in Oracle Database, download Needham's new e-book, Securing Oracle Database 12c: A Technical Primer.

  • Autoscaling in a modern world&hellip;. Part 4

    - by Steve Loethen
    Now that I have the rules and services XML files in the cloud, it is time to sever the bounds of earth and live totally in the cloud.  I have to host the Autoscaling object in Azure as well, point it to the rules, tell it the management certs and get out of the way. A couple of questions.  Where to host?  The most obvious place to me was a worker role.  A simple, single purpose worker role, doing nothing but watching my app.  Here are the steps I used. 1) Created a project.  Separate project from my web site.  I wanted to be able to run the web in the cloud and the autoscaler local for debugging purposes.  Seemed like the easiest way.  2) Add the Wasabi block to the project. 3) Configure the settings.  I used the same settings used for the console app.  It points to the same web role, uses the same rules file.  4) Make sure the certification needed to manage the role is added to the cert store in the sky (“LocalMachine” and “My” are default locations). I ran the worker role in the local fabric.  It worked.  I then published to the cloud, and verified it worked again.  Here is what my code looked like. public override bool OnStart() { Trace.WriteLine("Set Default Connection Limit", "Information"); // Set the maximum number of concurrent connections ServicePointManager.DefaultConnectionLimit = 12; Trace.WriteLine("Set up configuration change code", "Information"); // set up config CloudStorageAccount.SetConfigurationSettingPublisher((configName, configSetter) => configSetter(RoleEnvironment.GetConfigurationSettingValue(configName))); Trace.WriteLine("Get current diagnostic configuration", "Information"); // Get current diagnostic configuration DiagnosticMonitorConfiguration dmc = DiagnosticMonitor.GetDefaultInitialConfiguration(); Trace.WriteLine("Set Diagnostic Buffer Size", "Information"); // Set Diagnostic Buffer size dmc.Logs.BufferQuotaInMB = 4; Trace.WriteLine("Set log transfer period", "Information"); // Set log transfer period dmc.Logs.ScheduledTransferPeriod = TimeSpan.FromMinutes(1); Trace.WriteLine("Set log verbosity", "Information"); // Set log filter to verbose dmc.Logs.ScheduledTransferLogLevelFilter = LogLevel.Verbose; Trace.WriteLine("Start the diagnostic monitor", "Information"); // Start the diagnostic monitor DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString", dmc); Trace.WriteLine("Get the current Autoscaler from the EntLib Container", "Information"); // Get the current Autoscaler from the EntLib Container scaler = EnterpriseLibraryContainer.Current.GetInstance<Autoscaler>(); Trace.WriteLine("Start the autoscaler", "Information"); // Start the autoscaler scaler.Start(); Trace.WriteLine("call the base class OnStart", "Information"); // call the base class OnStart return base.OnStart(); } public override void OnStop() { Trace.WriteLine("Stop the Autoscaler", "Information"); // Stop the Autoscaler scaler.Stop(); } I did have to turn on some basic logging for wasabi, which will cover in the next post.  This let me figure out that I hadn’t done the certificate step.

  • Improving performance of a particle system (OpenGL ES)

    - by Jason
    I'm in the process of implementing a simple particle system for a 2D mobile game (using OpenGL ES 2.0). It's working, but it's pretty slow. I start getting frame rate battering after about 400 particles, which I think is pretty low. Here's a summary of my approach: I start with point sprites (GL_POINTS) rendered in a batch just using a native float buffer (I'm in Java-land on Android, so that translates as a java.nio.FloatBuffer). On GL context init, the following are set: GLES20.glViewport(0, 0, width, height); GLES20.glClearColor(0.0f, 0.0f, 0.0f, 0.0f); GLES20.glEnable(GLES20.GL_CULL_FACE); GLES20.glDisable(GLES20.GL_DEPTH_TEST); Each draw frame sets the following: GLES20.glEnable(GLES20.GL_BLEND); GLES20.glBlendFunc(GLES20.GL_ONE, GLES20.GL_ONE_MINUS_SRC_ALPHA); And I bind a single texture: GLES20.glActiveTexture(GLES20.GL_TEXTURE0); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, textureHandle); GLES20.glUniform1i(mUniformTextureHandle, 0); Which is just a simple circle with some blur (and hence some transparency) http://cl.ly/image/0K2V2p2L1H2x Then there are a bunch of glVertexAttribPointer calls: mBuffer.position(position); mGlEs20.glVertexAttribPointer(mAttributeRGBHandle, valsPerRGB, GLES20.GL_FLOAT, false, stride, mBuffer); ...4 more of these Then I'm drawing: GLES20.glUniformMatrix4fv(mUniformProjectionMatrixHandle, 1, false, Camera.mProjectionMatrix, 0); GLES20.glDrawArrays(GLES20.GL_POINTS, 0, drawCalls); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, 0); My vertex shader does have some computation in it, but given that they're point sprites (with only 2 coordinate values) I'm not sure this is the problem: #ifdef GL_ES // Set the default precision to low. precision lowp float; #endif uniform mat4 u_ProjectionMatrix; attribute vec4 a_Position; attribute float a_PointSize; attribute vec3 a_RGB; attribute float a_Alpha; attribute float a_Burn; varying vec4 v_Color; void main() { vec3 v_FGC = a_RGB * a_Alpha; v_Color = vec4(v_FGC.x, v_FGC.y, v_FGC.z, a_Alpha * (1.0 - a_Burn)); gl_PointSize = a_PointSize; gl_Position = u_ProjectionMatrix * a_Position; } My fragment shader couldn't really be simpler: #ifdef GL_ES // Set the default precision to low. precision lowp float; #endif uniform sampler2D u_Texture; varying vec4 v_Color; void main() { gl_FragColor = texture2D(u_Texture, gl_PointCoord) * v_Color; } That's about it. I had read that transparent pixels in point sprites can cause issues, but surely not at only 400 points? I'm running on a fairly new device (12 month old Galaxy Nexus). My question is less about my approach (although I'm open to suggestion) but more about whether there are any specific OpenGL "no no's" that have leaked into my code. I'm sure there's GL master out there facepalming right now... I'd love to hear any critique.

  • Migrating SQL Server Compact Edition (SQL CE) database to SQL Server using Web Matrix

    - by Harish Ranganathan
    One of the things that is keeping us busy is the Web Camps we are delivering across 5 cities.  If you are a reader of this blog, and also attended one of these web camps, there is a good chance that you have seen me since I was there in all the places, so far.  The topics that we cover include Visual Studio 2010 SP1, SQL CE, ASP.NET MVC & HTML5.  Whenever I talk about SQL CE, the immediate response is that, people are wow that Microsoft has shipped a FREE compact edition database, which is an embedded database that can be x-copy deployed.  If you think, well didn’t Microsoft ship SQL Express which is FREE?  The difference is that, SQL Express runs as a service in the machine (if you open SQL Configuration Manager, you can notice that SQL Express is running as a service along with your SQL Server Engine (if you have installed ).  This makes it that, even if you are willing to use SQL Express when you deploy your application, it needs to be installed on the production machine (hosting provider) and it needs to run as a service.  Many hosters don’t allow such services to run on their space. SQL CE comes as a x-Copy deploy-able database with just a few DLLs required to run it on the machine and they don’t even need to be installed in GAC on the production machine.  In fact, if you have Visual Studio 2010 SP1 installed, you can use the “Add Deployable Dependencies” option in Project-Properties and it would detect that SQL CE is something you would probably want to add as a deploy-able dependency for your project.  With that, it bundles the required DLLs as a part of the “_bin_deployableAssemblies” folder.  So your project can be x-Copy deployed and just works fine. However, SQL CE has the limit of 4GB storage space.  Real world applications often require more than just 4GB of data storage and it often turns out that people would like to use SQL CE for development/ramp up stages but would like to migrate to full fledged SQL Server after a while.  So, its only natural that the question arises “How do I move my SQL CE database to SQL Server”  And honestly, it doesn’t come across as a straight forward support.  I was talking to Ambrish Mishra (PM in SQL CE Team, Hyderabad) since I got this question in almost all the places where we talked about SQL CE.   He was kind enough to demonstrate how this can be accomplished using Web Matrix.  Open Web Matrix (Web Matrix can be installed for free from www.microsoft.com/web) and click on “Site from Template” Click on the “Bakery” template (since by default it uses a SQL CE database and has all the required sample data) and click “Ok”. In the project, you can navigate to the Database tab and will be able to find that the Bakery site uses a SQL CE database “bakery.sdf” Select the “bakery.sdf” and you will be able to see the “Migrate” button on the top right Once you click on the “Migrate” button, you will notice that the popup wizard opens up and by default is configured for SQL Express.  You can edit the same to point to your local SQL Server instance, or a remote server. Upon filling in the Server Name, Username and Password, when you click “Ok”, couple of things happen.  1. The database is migrated to SQL Server (local or remote – subject to permissions on remote server).   You can open up SQL Server Management Studio and connect to the server to verify that the “bakery” database exists under “Databases” node. 2. You can also notice that in Web Matrix, when you navigate to the “Files” tab and open up the web.config file, connection string now points to the SQL Server instance (yes, the Migrate button was smart enough to make this change too ) And there it is, your SQL Server Compact Edition database, now migrated to SQL Server!! In a future post, I would explain the steps involved when using Visual Studio. Cheers !!!

    As we all know as coders, things like logging are never important.  Our code will work right the first time.  So, you can understand my surprise when the first time I deployed the autoscaling worker role to the actual Azure fabric, it did not scale.  I mean, it worked on my machine.  How dare the datacenter argue with that.  So, how did I track down the problem?  (turns out, it was not so much code as lack of the right certificate)  When I ran it local in the developer fabric, I was able to see a wealth of information.  Lots of periodic status info every time the autoscalar came around to check on my rules and decide to act or not.  But that information was not making it to Azure storage.  The diagnostics were not being transferred to where I could easily see and use them to track down why things were not being cooperative.  After a bit of digging, I discover the problem.  You need to add a bit of extra configuration code to get the correct information stored for you.  I added the following to my app.config: Code Snippet <system.diagnostics>     <sources>         <source name="Autoscaling General"switchName="SourceSwitch"           switchType="System.Diagnostics.SourceSwitch" >         <listeners>           <add name="AzureDiag" />             <remove name="Default"/>         </listeners>       </source>         <source name="Autoscaling Updates"switchName="SourceSwitch"           switchType="System.Diagnostics.SourceSwitch" >         <listeners>           <add name="AzureDiag" />             <remove name="Default"/>         </listeners>       </source>     </sources>     <switches>       <add name="SourceSwitch"           value="Verbose, Information, Warning, Error, Critical" />     </switches>     <sharedListeners>       <add type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener,Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35" name="AzureDiag"/>     </sharedListeners>     <trace>       <listeners>         <add             type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener,Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35" name="AzureDiagnostics">           <filter type="" />         </add>       </listeners>     </trace>   </system.diagnostics> Suddenly all the rich tracing info I needed was filling up my storage account.  After a few cycles of trying to attempting to scale, I identified the cert problem, uploaded a correct certificate, and away it went.  I hope this was helpful.

  • Java - Resize images upon class instantiation

    - by Tyler J Fisher
    Hey StackExchange GameDev community, I'm attempting to: Resize series of sprites upon instantiation of the class they're located in (x2) I've attempted to use the following code to resize the images, however my attempts have been unsuccessful. I have been unable to write an implementation that is even compilable, so no error codes yet. wLeft.getScaledInstance(wLeft.getWidth()*2, wLeft.getHeight()*2, Image.SCALE_FAST); I've heard that Graphics2D is the best option. Any suggestions? I think I'm probably best off loading the images into a Java project, resizing the images then outputting them to a new directory so as not to have to resize each sprite upon class instantiation. What do you think? Photoshopping each individual sprite is out of the question, unless I used a macro. Code: package game; //Import import java.awt.Image; import javax.swing.ImageIcon; public class Mario extends Human { Image wLeft = new ImageIcon("sprites\\mario\\wLeft.PNG").getImage(); //Constructor public Mario(){ super("Mario", 50); wLeft.getScaledInstance(wLeft.getWidth()*2, wLeft.getHeight()*2, Image.SCALE_FAST); } Thanks! Note: not homework, just thought Mario would be a good, overused starting point in game dev.

  • How the "migrations" approach makes database continuous integration possible

    - by David Atkinson
    Testing a database upgrade script as part of a continuous integration process will only work if there is an easy way to automate the generation of the upgrade scripts. There are two common approaches to managing upgrade scripts. The first is to maintain a set of scripts as-you-go-along. Many SQL developers I've encountered will store these in a folder prefixed numerically to ensure they are ordered as they are intended to be run. Occasionally there is an accompanying document or a batch file that ensures that the scripts are run in the defined order. Writing these scripts during the course of development requires discipline. It's all too easy to load up the table designer and to make a change directly to the development database, rather than to save off the ALTER statement that is required when the same change is made to production. This discipline can add considerable overhead to the development process. However, come the end of the project, everything is ready for final testing and deployment. The second development paradigm is to not do the above. Changes are made to the development database without considering the incremental update scripts required to effect the changes. At the end of the project, the SQL developer or DBA, is tasked to work out what changes have been made, and to hand-craft the upgrade scripts retrospectively. The end of the project is the wrong time to be doing this, as the pressure is mounting to ship the product. And where data deployment is involved, it is prudent not to feel rushed. Schema comparison tools such as SQL Compare have made this latter technique more bearable. These tools work by analyzing the before and after states of a database schema, and calculating the SQL required to transition the database. Problem solved? Not entirely. Schema comparison tools are huge time savers, but they have their limitations. There are certain changes that can be made to a database that can't be determined purely from observing the static schema states. If a column is split, how do we determine the algorithm required to copy the data into the new columns? If a NOT NULL column is added without a default, how do we populate the new field for existing records in the target? If we rename a table, how do we know we've done a rename, as we could equally have dropped a table and created a new one? All the above are examples of situations where developer intent is required to supplement the script generation engine. SQL Source Control 3 and SQL Compare 10 introduced a new feature, migration scripts, allowing developers to add custom scripts to replace the default script generation behavior. These scripts are committed to source control alongside the schema changes, and are associated with one or more changesets. Before this capability was introduced, any schema change that required additional developer intent would break any attempt at auto-generation of the upgrade script, rendering deployment testing as part of continuous integration useless. SQL Compare will now generate upgrade scripts not only using its diffing engine, but also using the knowledge supplied by developers in the guise of migration scripts. In future posts I will describe the necessary command line syntax to leverage this feature as part of an automated build process such as continuous integration.

  • Knowledge Pathways Designer - Recommended Settings

    - by ted.henson
    The General page of the Options dialog box contains the application preferences for Knowledge Pathways Designer. It is recommended that you leave certain settings as they are, unless you have a specific reason for changing them. The following are a few of the settings on the General page with an explanation of the recommended setting. They are in the order they appear on the page: Allow version 2.0 style links: This option should remain disabled unless you were using content that was created using version 2.0 of Knowledge Pathways and you want the same linking functionality that existed in that version 2.0. This feature enables you to reuse parts of titles that contain no AUs. However, keep in mind that this type of link is not a true link, but a cross between a copy and a link. To create a 2.0 style link, you drag and drop sections between titles. You can only create 2.0 style links to sections that belong to the Title AU. When creating a version 2.0 style link, your mouse pointer will change to indicate a 2.0 link is being created. Confirm deletion of outline items and Confirm deletion of titles: It is recommended that these options remain enabled to avoid deleting something by accident. Display tracking data loss warning when opening a published title: It recommended that this option be enabled so you will receive the warning message when you open the development copy of a title, reminding you of the implications of your changes. ulCopy files when converting a Section to an Assignable Unit: This option should remain enabled unless you have a specific reason for not copying the files. If this is disabled, you will (in effect) lose your content files upon converting because they will not be copied to the new AU directory on the content root. In this case, you would need to use Windows Explorer to copy your files manually. Working with Spelling Options All of the spelling options are enabled by default. Your design team can review these options to determine if you want to make changes, depending upon your specific needs. Understanding Dictionary Options You should leave the dictionary options as they are, unless you have a specific reason for changing them. While you can delete the user (customizable) dictionary, doing so is not recommended. Setting Check In/Check Out Options The ability to check in and check out titles and AUs will impact the efficiency of your design team. Decide what your check in and check out processes are before you start developing titles. The Check In/Check Out page of the Options dialog box contains two options that affect what happens when you open a title using the Open Title dialog box. Both of these options are enabled by default and are described below: Check Out for editing enabled: This option ensures that the Check Out for editing option will be selected when you open the development copy of a title from the Open Title dialog box. If this option is disabled, you must select the Check Out for editing option every time you want to check out a title for editing. Attempt to Check Out for entire branch: When this option is enabled, Designer checks out the selected title and all AUs and sections that are part of that title, provided they are available for check out. If this option is disabled, you will only check out the Title AU and anything that belongs to that Title AU (e.g., sections, questions, etc.), but not other AUs. The Check In/Check Out page of the Options dialog box also contains options that control what happens when you close a title. You can choose one option in the Check In when Closing a Title area. The option selected is a matter of preference and you should determine which option is most appropriate for your design team.

  • Flex 4 + Apache Ant, Cannot Load FlashPunk Libraries

    - by SquareCrow
    I have been searching google, Apache Docs*, and FlashPunk forums looking for an answer to this: I cannot get Ant/Flex to find and compile the FlashPunk libraries. Here is my build.xml. [code] <!-- Fetch the JAR full of Flex tasks if it is not already in the source directory --> <copy file="${FLEX_HOME}/ant/lib/flexTasks.jar" todir="${SOURCE_PATH}"/> <!-- Add flextasks to the project --> <taskdef resource="flexTasks.tasks" classpath="${SOURCE_PATH}/flexTasks.jar"></taskdef> <!-- Release build Flash Player 10.1 --> <target name="build"> <!-- Build the FlashPunk library --> <echo message="building swc..." /> <compc output="FlashPunk.swc" keep-generated-actionscript="false" incremental="false" optimize="false" debug="true" use-network="false"> <include-sources dir="${FLASHPUNK_PATH}/net" includes="**/* flashpunk/utils/* flashpunk/masks/*" excludes="**/*.TTF **/*.png"/> <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml"/> </compc> <echo message="building swf..." /> <mxmlc file="${SOURCE_PATH}/epOne.as" output="${OUTPUT_PATH}/epOne.swf" debug="false" incremental="false" strict="true" accessible="false" link-report="link_report.xml" static-link-runtime-shared-libraries="true"> <optimize>true</optimize> </mxmlc> </target> [/code] Results in many errors of the type "Definition net.flashpunk.masks:Grid could not be found" even though when I open the directories I can see the *.AS files right there. Sorry if this is very basic. I am piecing together knowledge of Ant from docs and tutorials. *I decided to use Ant because neither FlashDevelop for Windows nor Eclipse for Linux seemto work for me.

  • Doing your first mock with JustMock

    - by mehfuzh
    In this post, i will start with a  more traditional mocking example that  includes a fund transfer scenario between two different currency account using JustMock.Our target interface that we will be mocking looks similar to: public interface ICurrencyService {     float GetConversionRate(string fromCurrency, string toCurrency); } Moving forward the SUT or class that will be consuming the  service and will be invoked by user [provided that the ICurrencyService will be passed in a DI style] looks like: public class AccountService : IAccountService         {             private readonly ICurrencyService currencyService;               public AccountService(ICurrencyService currencyService)             {                 this.currencyService = currencyService;             }               #region IAccountService Members               public void TransferFunds(Account from, Account to, float amount)             {                 from.Withdraw(amount);                 float conversionRate = currencyService.GetConversionRate(from.Currency, to.Currency);                 float convertedAmount = amount * conversionRate;                 to.Deposit(convertedAmount);             }               #endregion         }   As, we can see there is a TransferFunds action implemented from IAccountService  takes in a source account from where it withdraws some money and a target account to where the transfer takes place using the provided conversion rate. Our first step is to create the mock. The syntax for creating your instance mocks is pretty much same and  is valid for all interfaces, non-sealed/sealed concrete instance classes. You can pass in additional stuffs like whether its an strict mock or not, by default all the mocks in JustMock are loose, you can use it as default valued objects or stubs as well. ICurrencyService currencyService = Mock.Create<ICurrencyService>(); Using JustMock, setting up your expectations and asserting them always goes with Mock.Arrang|Assert and this is pretty much same syntax no matter what type of mocking you are doing. Therefore,  in the above scenario we want to make sure that the conversion rate always returns 2.20F when converting from GBP to CAD. To do so we need to arrange in the following way: Mock.Arrange(() => currencyService.GetConversionRate("GBP", "CAD")).Returns(2.20f).MustBeCalled(); Here, I have additionally marked the mock call as must. That means it should be invoked anywhere in the code before we do Mock.Assert, we can also assert mocks directly though lamda expressions  but the more general Mock.Assert(mocked) will assert only the setups that are marked as "MustBeCalled()”. Now, coming back to the main topic , as we setup the mock, now its time to act on it. Therefore, first we create our account service class and create our from and to accounts respectively. var accountService = new AccountService(currencyService);   var canadianAccount = new Account(0, "CAD"); var britishAccount = new Account(0, "GBP"); Next, we add some money to the GBP  account: britishAccount.Deposit(100); Finally, we do our transfer by the following: accountService.TransferFunds(britishAccount, canadianAccount, 100); Once, everything is completed, we need to make sure that things were as it is we have expected, so its time for assertions.Here, we first do the general assertions: Assert.Equal(0, britishAccount.Balance); Assert.Equal(220, canadianAccount.Balance); Following, we do our mock assertion,  as have marked the call as “MustBeCalled” it will make sure that our mock is actually invoked. Moreover, we can add filters like how many times our expected mock call has occurred that will be covered in coming posts. Mock.Assert(currencyService); So far, that actually concludes our  first  mock with JustMock and do stay tuned for more. Enjoy!!

  • Edit the Windows Live Writer Custom Dictionary

    - by Matthew Guay
    Windows Live Writer is a great tool for writing and publishing posts to your blog, but its spell check unfortunately doesn’t include many common tech words.  Here’s how you can easily edit your custom dictionary and add your favorite words. Customize Live Writer’s Dictionary Adding an individual word to the Windows Live Writer dictionary works as you would expect.  Right-click on a word and select Add to dictionary. And changing the default spell check settings is easy too.  In the menu, click Tools, then Options, and select the Spelling tab in this dialog.  Here you can choose your dictionary language and turn on/off real-time spell checking and other settings. But there’s no obvious way to edit your custom dictionary.  Editing the custom dictionary directly is nice if you accidently add a misspelled word to your dictionary and want to remove it, or if you want to add a lot of words to the dictionary at once. Live Writer actually stores your custom dictionary entries in a plain text file located in your appdata folder.  It is saved as User.dic in the C:\Users\user_name\AppData\Roaming\Windows Live Writer\Dictionaries folder.  The easiest way to open the custom dictionary is to enter the following in the Run box or the address bar of an Explorer window: %appdata%\Windows Live Writer\Dictionaries\User.dic   This will open the User.dic file in your default text editor.  Add any new words to the custom dictionary on separate lines, and delete any misspelled words you accidently added to the dictionary.   Microsoft Office Word also stores its custom dictionary in a plain text file.  If you already have lots of custom words in it and want to import them into Live Writer, enter the following in the Run command or Explorer’s address bar to open Word’s custom dictionary.  Then copy the words, and past them into your Live Writer custom dictionary file. %AppData%\Microsoft\UProof\Custom.dic Don’t forget to save the changes when you’re done.  Note that the changes to the dictionary may not show up in Live Writer’s spell check until you restart the program.  If it’s currently running, save any posts you’re working on, exit, and then reopen, and all of your new words should be in the dictionary. Conclusion Whether you use Live Writer daily in your job or occasionally post an update to a personal blog, adding your own custom words to the dictionary can save you a lot of time and frustration in editing.  Plus, if you’ve accidently added a misspelled word to the dictionary, this is a great way to undo your mistake and make sure your spelling is up to par!

  • rsync'd a folder, folder doesn't show up, but free disk space decreased

    - by Patrick
    I am currently trying to switch from mac to windows/ubuntu dual boot (on 2 seperate internal HDDs), but ran into some trouble restoring my documents. I am not sure all the information below is necessary, but if I knew how to solve it, I wouldn't ask it here. I backed up my mac before buying this laptop on an external HDD with Carbon Copy Cloner. I wanted to put these files on my user folder on my windows HDD, but I could not do that from inside windows (HFS+ format of mac), so I used rsync from inside Ubuntu to copy the documents from the ext hdd to the windows partition. It seemed like it went okay, but from inside windows (and later also Ubuntu) the folder didn't show up. My free HDD space, however, has reduced with about 200 GB (the size of the backup) when looking at the disk properties (from inside Windows and Ubuntu). rsync command I used: rsync -av /media/patrick/Toshiba\ 1.5T/Users/patrickvandenberg/ /media/patrick/Windows8_OS/Users/Patrick/MacBackup/ Folder does not exist: patrick@patrick-Lenovo-IdeaPad-Y410P:~$ cd /media/patrick/Windows8_OS/Users/Patrick/MacBackup bash: cd: /media/patrick/Windows8_OS/Users/Patrick/MacBackup: No such file or directory Size of disk: patrick@patrick-Lenovo-IdeaPad-Y410P:~$ du -hs /media/patrick/Windows8_OS/ 195G /media/patrick/Windows8_OS/ Size of disk according to Disk properties: http://i.stack.imgur.com/OteMX.png (not enough rep to insert the image)

  • Regex syntax question - trying to understand

    - by Asaf Chertkoff
    i don't know if this question belong here or no, but it is worth a shot. i'm a self taught php programmer and i'm only now starting to grasp the regex stuff. i'm pretty aware of its capabilities when it is done right, but this is something i need to dive in too. so maybe someone can help me, and save me so hours of experiment. i have this string: here is the <a href="http://www.google.com" class="ttt" title="here"><img src="http://www.somewhere.com/1.png" alt="some' /></a> and there is <a href="#not">not</a> a chance... now, i need to perg_match this string and search for the a href tag that has an image in it, and replace it with the same tag with a small difference: after the title attribute inside the tag, i'll want to add a rel="here" attribute. of course, it should ignore links (a href's) that doesn't have img tag inside. help will be appreciated, thanks.

  • Lies, damned lies, and statistics Part 2

    - by Maria Colgan
    There was huge interest in our OOW session last year on Managing Optimizer Statistics. It seems statistics and the maintenance of them continues to baffle people. In order to help dispel the mysteries surround statistics management we have created a two part white paper series on Optimizer statistics.  Part one of this series was released in November last years and describes in detail, with worked examples, the different concepts of Optimizer statistics. Today we have published part two of the series, which focuses on the best practices for gathering statistics, and examines specific use cases including, the fears that surround histograms and statistics management of volatile tables like Global Temporary Tables. Here is a quick look at the Introduction and the start of the paper. You can find the full paper here. Happy Reading! Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman","serif";} Introduction The Oracle Optimizer examines all of the possible plans for a SQL statement and picks the one with the lowest cost, where cost represents the estimated resource usage for a given plan. In order for the Optimizer to accurately determine the cost for an execution plan it must have information about all of the objects (table and indexes) accessed in the SQL statement as well as information about the system on which the SQL statement will be run. This necessary information is commonly referred to as Optimizer statistics. Understanding and managing Optimizer statistics is key to optimal SQL execution. Knowing when and how to gather statistics in a timely manner is critical to maintaining acceptable performance. This whitepaper is the second of a two part series on Optimizer statistics. The first part of this series, Understanding Optimizer Statistics, focuses on the concepts of statistics and will be referenced several times in this paper as a source of additional information. This paper will discuss in detail, when and how to gather statistics for the most common scenarios seen in an Oracle Database. The topics are · How to gather statistics · When to gather statistics · Improving the efficiency of gathering statistics · When not to gather statistics · Gathering other types of statistics How to gather statistics The preferred method for gathering statistics in Oracle is to use the supplied automatic statistics-gathering job. Automatic statistics gathering job The job collects statistics for all database objects, which are missing statistics or have stale statistics by running an Oracle AutoTask task during a predefined maintenance window. Oracle internally prioritizes the database objects that require statistics, so that those objects, which most need updated statistics, are processed first. The automatic statistics-gathering job uses the DBMS_STATS.GATHER_DATABASE_STATS_JOB_PROC procedure, which uses the same default parameter values as the other DBMS_STATS.GATHER_*_STATS procedures. The defaults are sufficient in most cases. However, it is occasionally necessary to change the default value of one of the statistics gathering parameters, which can be accomplished by using the DBMS_STATS.SET_*_PREF procedures. Parameter values should be changed at the smallest scope possible, ideally on a per-object bases. You can find the full paper here. Happy Reading! +Maria Colgan

  • Ongoing confusion about ivars and properties in objective C

    - by Earl Grey
    After almost 8 months being in ios programming, I am again confused about the right approach. Maybe it is not the language but some OOP principle I am confused about. I don't know.. I was trying C# a few years back. There were fields (private variables, private data in an object), there were getters and setters (methods which exposed something to the world) ,and properties which was THE exposed thing. I liked the elegance of the solution, for example there could be a class that would have a property called DailyRevenue...a float...but there was no private variable called dailyRevenue, there was only a field - an array of single transaction revenues...and the getter for DailyRevenue property calculated the revenue transparently. If somehow the internals of daily revenue calculation would change, it would not affect somebody who consumed my DailyRevenue property in any way, since he would be shielded from getter implementation. I understood that sometimes there was , and sometimes there wasn't a 1-1 relationship between fields and properties. depending on the requirements. It seemed ok in my opinion. And that properties are THE way to acces the data in object. I know the difference betweeen private, protected, and public keyword. Now lets get to objectiveC. On what factor should I base my decision about making someting only an ivar or making it as a property? Is the mental model the same as I describe above? I know that ivars are "protected" by default, not "private" asi in c#..But thats ok I think, no big deal for my presnet level of understanding the whole ios development. The point is ivars are not accesible from outside (given i don't make them public..but i won't). The thing that clouds my clear understanding is that I can have IBOutlets from ivars. Why am I seeing internal object data in the UI? *Why is it ok?* On the other hand, if I make an IBOutlet from property, and I do not make it readonly, anybody can change it. Is this ok too? Let's say I have a ParseManager object. This object would use a built in Foundation framework class called NSXMLParser. Obviously my ParseManager will utilize this nsxmlparser's capabilities but will also do some additional work. Now my question is, who should initialize this NSXMLParser object and in which way should I make a reference to it from the ParseManager object, when there is a need to parse something. A) the ParseManager -1) in its default init method (possible here ivar - or - ivar+ppty) -2) with lazyloading in getter (required a ppty here) B) Some other object - who will pass a reference to NSXMLParser object to the ParseManager object. -1) in some custom initializer (initWithParser:(NSXMLPArser *) parser) when creating the ParseManager object.. A1 - the problem is, we create a parser and waste memory while it is not yet needed. However, we can be sure that all methods that are part ot ParserManager object, can use the ivar safely, since it exists. A2 - the problem is, the nsxmlparser is exposed to outside world, although it could be read only. Would we want a parser to be exposed in some scenario? B1 - this could maybe be useful when we would want to use more types of parsers..i dont know... I understand that architectural requirements and and language is not the same. But clearly the two are in relation. How to get out of that mess of my? Please bear with me, I wasn't able to come up with a single ultimate question. And secondly, it's better to not scare me with some superadvanced newspeak that talks about some crazy internals (what the compiler does) and edge cases.

  • Entity System with C++

    - by Dono
    I'm working on a game engine using the Entity System and I have some questions. How I see Entity System : Components : A class with attributs, set and get. Sprite Physicbody SpaceShip ... System : A class with a list of components. (Component logic) EntityManager Renderer Input Camera ... Entity : Just a empty class with a list of components. What I've done : Currently, I've got a program who allow me to do that : // Create a new entity/ Entity* entity = game.createEntity(); // Add some components. entity->addComponent( new TransformableComponent() ) ->setPosition( 15, 50 ) ->setRotation( 90 ) ->addComponent( new PhysicComponent() ) ->setMass( 70 ) ->addComponent( new SpriteComponent() ) ->setTexture( "name.png" ) ->addToSystem( new RendererSystem() ); My questions Did the system stock a list of components or a list of entities ? In the case where I stock a list of entities, I need to get the component of this entities on each frame, that's probably heavy isn't it ? Did the system stock a list of components or a list of entities ?

  • Libgdx detect when player is outside of screen

    - by Rockyy
    Im trying to learn libGDX (coming from XNA/MonoDevelop), and I'm making a super simple test game to get to know it better. I was wondering how to detect if the player sprite is outside of the screen and make it so it is impossible to go outside of the screen edges. In XNA you could do something like this: // Prevent player from moving off the left edge of the screen if (player.Position.X < 0) player.Position = new Vector2(0, player.Position.Y); How is this achieved in libgdx? I think it's the Stage that handles the 2D viewport in libgdx? This is my code so far: private Texture texture; private SpriteBatch batch; private Sprite sprite; @Override public void create () { float w = Gdx.graphics.getWidth(); float h = Gdx.graphics.getHeight(); batch = new SpriteBatch(); texture = new Texture(Gdx.files.internal("player.png")); sprite = new Sprite(texture); sprite.setPosition(w/2 -sprite.getWidth()/2, h/2 - sprite.getHeight()/2); } @Override public void render () { Gdx.gl.glClearColor(1, 1, 1, 1); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); if(Gdx.input.isKeyPressed(Input.Keys.LEFT)){ if(Gdx.input.isKeyPressed(Input.Keys.CONTROL_LEFT)) sprite.translateX(-1f); else sprite.translateX(-10.0f); } if(Gdx.input.isKeyPressed(Input.Keys.RIGHT)){ if(Gdx.input.isKeyPressed(Input.Keys.CONTROL_LEFT)) sprite.translateX(1f); else sprite.translateX(10f); } batch.begin(); sprite.draw(batch); batch.end(); }

  • HPCM 11.1.2.x - Outline Optimisation for Calculation Performance

    - by Jane Story
    When an HPCM application is first created, it is likely that you will want to carry out some optimisation on the HPCM application’s Essbase outline in order to improve calculation execution times. There are several things that you may wish to consider. Because at least one dense dimension for an application is required to deploy from HPCM to Essbase, “Measures” and “AllocationType”, as the only required dimensions in an HPCM application, are created dense by default. However, for optimisation reasons, you may wish to consider changing this default dense/sparse configuration. In general, calculation scripts in HPCM execute best when they are targeting destinations with one or more dense dimensions. Therefore, consider your largest target stage i.e. the stage with the most assignment destinations and choose that as a dense dimension. When optimising an outline in this way, it is not possible to have a dense dimension in every target stage and so testing with the dense/sparse settings in every stage is the key to finding the best configuration for each individual application. It is not possible to change the dense/sparse setting of individual cloned dimensions from EPMA. When a dimension that is to be repeated in multiple stages, and therefore cloned, is defined in EPMA, every instance of that dimension has the same storage setting. However, such manual changes may not be preserved in all cases. Please see below for full explanation. However, once the application has been deployed from EPMA to HPCM and from HPCM to Essbase, it is possible to make the dense/sparse changes to a cloned dimension directly in Essbase. This can be done by editing the properties of the outline in Essbase Administration Services (EAS) and manually changing the dense/sparse settings of individual dimensions. There are two methods of deployment from HPCM to Essbase from 11.1.2.1. There is a “replace” deploy method and an “update” deploy method: “Replace” will delete the Essbase application and replace it. If this method is chosen, then any changes made directly on the Essbase outline will be lost. If you use the update deploy method (with or without archiving and reloading data), then the Essbase outline, including any manual changes you have made (i.e. changes to dense/sparse settings of the cloned dimensions), will be preserved. Notes If you are using the calculation optimisation technique mentioned in a previous blog to calculate multiple POVs (https://blogs.oracle.com/pa/entry/hpcm_11_1_2_optimising) and you are calculating all members of that POV dimension (e.g. all months in the Period dimension) then you could consider making that dimension dense. Always review Block sizes after all changes! The maximum block size recommended in the Essbase Database Administrator’s Guide is 100k for 32 bit Essbase and 200k for 64 bit Essbase. However, calculations may perform better with a larger than recommended block size provided that sufficient memory is available on the Essbase server. Test different configurations to determine the most optimal solution for your HPCM application. Please note that this blog article covers HPCM outline optimisation only. Additional performance tuning can be achieved by methodically testing database settings i.e data cache, index cache and/or commit block settings. For more information on Essbase tuning best practices, please review these items in the Essbase Database Administrators Guide. For additional information on the commit block setting, please see the previous PA blog article https://blogs.oracle.com/pa/entry/essbase_11_1_2_commit

  • Extract High Quality Icons from Files Using a Free Tool

    - by Lori Kaufman
    If you need to extract an icon from a program file or other type of file (such as .dll files), there are many free tools available that make the task easy. However, very few will extract high quality icon images from the files. Most free icon extraction tools will extract smaller icon image sizes, such as 16×16, 32×32, or 48×48 pixels. Some icons come in larger sizes, such as icons used in Windows. There is a free, small utility, called BeCyIconGrabber, that allows you to view and save icons and cursors of any size contained in .exe, .dll, .icl, .ocx, .cpl, .src, .ico, and .cur files. You can save the extracted icons individually as a .png file, .bmp file, .ico file, or .cur file, or in groups within resource libraries, i.e., .dll or .icl files. BeCyIconGrabber can be downloaded as an installable file or as a portable executable that does not need to be installed. We downloaded the portable file.

  • Ubuntu 12.04 Install - Black Screen - No Grub - Have run Boot Repair Disk

    - by Pat
    Day 4 of my purgatory. History: Had problems with live CD at first, had to set the "nomodeset" option ... and then it worked fine. Installed Ubuntu "Alongside" Windows XP from live CD (NOT wubi) Upon reboot after installation, I get the BIOS ... and then a black screen. If I hit shift after the BIOS screen I get text that says "loading GRUB ..", but then no GRUB ... just a black screen. What I have tried to do: Total re-installation ... 3 times now. Also tried with wubi, same black screen. Have gone back to the normal (non-wubi) install. After installation, I tried re-booting the live cd ... and trying to change GRUB file using: sudo gedit /etc/default/grub ... to "nomodeset" and "timeout=10" ... but won't let me save my changes because I'm using the live cd "in memory" system and don't have permissions to the disks (I think). I tried logging in ... but it won't let me. I then read many posts on this site. I'm stuck. This morning, I ran the "boot repair disk". Results here: http://paste.ubuntu.com/1132333/ What I think is wrong: Since I can get the live CD to run (perfectly) with the "nomodeset" option, I think all I need to do is get to GRUB to change that ... but I can't get to GRUB. Appreciate any advice. Pat Day 5 ... I downloaded "Super Grub 2 Disk" from: http://www.supergrubdisk.org/super-grub2-disk/ This looks promising. I can boot the disk and it brings me to a GRUB program that allows me to: 1) Boot to Windows ... which works 2) Boot to Ubuntu ... which does NOT work When I choose boot to Ubuntu, I get lines across the screen which is an obvious video card problem. Likely because I need to set the "nomodeset" option. So, I attempted to use super grub2 to edit the grub file ... but it is TOTALLY different than the Ubuntu grub file ... and I don't know where to put the "nomodeset" option. Still stuck ... The bottom line is that: 1) I need to edit /etc/default/grub on sda(1) ... which is my boot drive ... to add the "nomodeset" option 2) To do that I need to get into grub ... but, I can't. Holding down shift just echo's "loading grub .." and then takes me to a black screen 3) I can boot to the live CD by setting nomodeset .... but I cannot access the hard disk as root ... I can't save my changes! Can anyone tell me how to login as root for the filesystem from the live CD ... so I can edit the grub file on the HARD DISK ... and then run update-grub??

  • Monitor and Control Memory Usage in Google Chrome

    - by Asian Angel
    Do you want to know just how much memory Google Chrome and any installed extensions are using at a given moment? With just a few clicks you can see just what is going on under the hood of your browser. How Much Memory are the Extensions Using? Here is our test browser with a new tab and the Extensions Page open, five enabled extensions, and one disabled at the moment. You can access Chrome’s Task Manager using the Page Menu, going to Developer, and selecting Task manager… Or by right clicking on the Tab Bar and selecting Task manager. There is also a keyboard shortcut (Shift + Esc) available for the “keyboard ninjas”. Sitting idle as shown above here are the stats for our test browser. All of the extensions are sitting there eating memory even though some of them are not available/active for use on our new tab and Extensions Page. Not so good… If the default layout is not to your liking then you can easily modify the information that is available by right clicking and adding/removing extra columns as desired. For our example we added Shared Memory & Private Memory. Using the about:memory Page to View Memory Usage Want even more detail? Type about:memory into the Address Bar and press Enter. Note: You can also access this page by clicking on the Stats for nerds Link in the lower left corner of the Task Manager Window. Focusing on the four distinct areas you can see the exact version of Chrome that is currently installed on your system… View the Memory & Virtual Memory statistics for Chrome… Note: If you have other browsers running at the same time you can view statistics for them here too. See a list of the Processes currently running… And the Memory & Virtual Memory statistics for those processes. The Difference with the Extensions Disabled Just for fun we decided to disable all of the extension in our test browser… The Task Manager Window is looking rather empty now but the memory consumption has definitely seen an improvement. Comparing Memory Usage for Two Extensions with Similar Functions For our next step we decided to compare the memory usage for two extensions with similar functionality. This can be helpful if you are wanting to keep memory consumption trimmed down as much as possible when deciding between similar extensions. First up was Speed Dial”(see our review here). The stats for Speed Dial…quite a change from what was shown above (~3,000 – 6,000 K). Next up was Incredible StartPage (see our review here). Surprisingly both were nearly identical in the amount of memory being used. Purging Memory Perhaps you like the idea of being able to “purge” some of that excess memory consumption. With a simple command switch modification to Chrome’s shortcut(s) you can add a Purge Memory Button to the Task Manager Window as shown below.  Notice the amount of memory being consumed at the moment… Note: The tutorial for adding the command switch can be found here. One quick click and there is a noticeable drop in memory consumption. Conclusion We hope that our examples here will prove useful to you in managing the memory consumption in your own Google Chrome installation. If you have a computer with limited resources every little bit definitely helps out.
