  • Share Folders & Files Between Vista and XP Machines

    - by Mysticgeek
    Since Microsoft has three operating systems in use, chances are you’ll find yourself needing to share files between XP, Vista, Windows 7, or some combination of the three. Here we take a look at sharing between a Vista and XP on your home network. Share Without Password Protected Sharing If you’re not worried about who’s accessing the files and folders, the easiest method is to disable Password Protected Sharing. So on the Vista machine open Network and Sharing Center. Under Sharing and Discovery make sure Network Discovery, File Sharing, and, Public Folder Sharing are turned on. Also turn off Password Protected Sharing… Now go into the Vista Public folder, located in C:\Users\Public, and add what you want to share or create a new folder. In this example we created a new folder called XP_Share and added some files to it. On the XP machine go into My Network Places and under Network Tasks click on View Workgroup Computers. Now you’ll see all of the computers on your network which should be part of the same Workgroup. Here we need to double-click on the Vista computer. And there we go…no password to enter so we can access the XP_Share folder or anything else that is located in the Public folder. Share with Password Protected Sharing If you want to keep Password Protected Sharing turned on, then we need to do things a little different. When it’s turned on and you try to access the Vista machine from XP, you’re prompted for a password, and no matter what you think the credentials are, you can’t get access…very annoying. So what we need to do is add the XP Machine as a user. Right-click on Computer from the Start Menu or desktop icon and select Manage from the context menu. The Computer Management screen opens up and you want to expand Local Users and Groups, then the Users folder. Then right-click any open area an select New User. Now create a new user name and password, you can also fill in the other fields if you want. Then make sure to uncheck User must change password at next logon and check the box next to Password never expires. Click the Create button and close out of the New User screen. You’ll then see the new user we created in the list and you can close out of the Computer Management window. Now back on the XP computer when you double-click on the Vista machine, your prompted to log in. Just type in the username and password you just created. Now you’ll have access to the Public folder contents. Set up Sharing on XP If you want to access a shared folder from the Vista computer located on the XP machine, it’s the same process in reverse. On the XP computer in Shared Documents, right-click on the folder you want to share and select Sharing and Security. Then select the radio button next to Share this folder and click Ok. Go into Computer Management and create a new user… Now from the Vista machine double click on the XP machine icon, enter the password, then access the folders and files you need. If you have multiple versions of Windows on your home network, you’ll now be able to access files and folders from each of them.

  • How to Use Sparklines in Excel 2010

    - by DigitalGeekery
    One of the cool features of Excel 2010 is the addition of Sparklines. A Sparkline is basically a little chart displayed in a cell representing your selected data set that allows you to quickly and easily spot trends at a glance. Inserting Sparklines on your Spreadsheet You will find the Sparklines group located on the Insert tab.   Select the cell or cells where you wish to display your Sparklines. Select the type of Sparkline you’d like to add to your spreadsheet. You’ll notice there are three types of Sparklines, Line, Column, and Win/Loss. We’ll select Line for our example. A Create Sparklines pops up and will prompt you to enter a Data Range you are using to create the Sparklines. You’ll notice that the location range (the range where the Sparklines will appear) is already filled in. You can type in the data range manually, or click and drag with your mouse across to select the data range. This will auto-fill the data range for you. Click OK when you are finished.   You will see your Sparklines appear in the desired cells.   Customizing Sparklines Select the one of more of the Sparklines to reveal the Design tab. You can display certain value points like high and low points, negative points, and first and last points by selecting the corresponding options from the Show group. You can also mark all value points by selecting  Markers. Select your desired Sparklines and click one of the included styles from the Style group on the Design tab. Click the down arrow on the lower right corner of the box to display additional pre-defined styles…   or select Sparkline Color or Marker Color options to fully customize your Sparklines. The Axis options allow additional options such as Date Axis Type, Plotting Data Left to Right, and displaying an axis point to represent the zero line in your data with Show Axis. Column Sparklines Column Sparklines display your data in individual columns as opposed to the Line view we’ve been using for our examples. Win/Loss Sparklines Win/Loss shows a basic positive or negative representation of your data set.   You can easily switch between different Sparkline types by simply selecting the current cells (individually or the entire group), and then clicking the desired type on the Design tab. For those that may be more visually oriented, Sparklines can be a wonderful addition to any spreadsheet. Are you just getting started with Office 2010?

  • Access Music from Amie Street in Boxee

    - by Mysticgeek
    One of our favorite sites for discovering new music is Amie Street. Today we take a look at the Amie Street app for Boxee that allows you to access your favorite tunes from the Boxee interface. Amie Street is a cool site that allows you to discover a lot of cool music from independent artists. What makes Amie Street unique is that most of the music starts out free, then the price goes up incrementally as its popularity grows. The Amie Street App for Boxee let’s you access music and playlists you’ve created on the site, with more features are on the way. For this example we’re using the mouse and keyboard, but of course you can also get to each section using your remote if you have one. Or you can turn your iPod touch into a Boxee remote too. Amie Street in Boxee To access the Amie Street app, launch Boxee and click on Apps from the main menu. Under the Search Sidebar type in Amie Street and select it from the results field.   Then you can add it to the My Apps section…and double-click on the icon. Click on Start to begin using it. You’ll be be presented with a Welcome screen where you can sign into your account. If you don’t have an account yet, there is also an option to go to the Amie Street site and create one. Enter in your account credentials… Now you’ll be able to access your Library, Playlists, Search for new tunes, and check out your Recommended bands and artists. Hover the pointer over an album to get a bit more info about it such as the music genre. You’ll be able to play the songs from the playlists you created on the Amie Street site. You can browse through the history of the music you’ve played as well. Not all the features of this app seem to work as you’d expect them to, and some of the features are not yet available like the Browse feature.   Conclusion At the time of this writing we weren’t able to purchase music or get additional information about the artists. As development continues on Boxee and this app, you can expect more of a full user experience and the ability to purchase music. Even though some of the features are a bit buggy or not available, if you’re a Boxee user and a fan of Amie Street, this is cool app to add to your collection.

  • What Counts For a DBA – Decisions

    - by Louis Davidson
    It’s Friday afternoon, and the lead DBA, a very talented guy, is getting ready to head out for two well-earned weeks of vacation, with his family, when this error message pops up in his inbox: Msg 211, Level 23, State 51, Line 1. Possible schema corruption. Run DBCC CHECKCATALOG. His heart sinks. It’s ten…no eight…minutes till it’s time to walk out the door. He glances around at his coworkers, competent to handle many problems, but probably not up to the challenge of fixing possible database corruption. What does he do? After a few agonizing moments of indecision, he clicks shut his laptop. He’ll just wait and see. It was unlikely to come to anything; after all, it did say “possible” schema corruption, not definite. In that moment, his fate was sealed. The start of the solution to the problem (run DBCC CHECKCATALOG) had been right there in the error message. Had he done this, or at least took two of those eight minutes to delegate the task to a coworker, then he wouldn’t have ended up spending two-thirds of an idyllic vacation (for the rest of the family, at least) dealing with a problem that got consistently worse as the weekend progressed until the entire system was down. When I told this story to a friend of mine, an opera fan, he smiled and said it described the basic plotline of almost every opera or ‘Greek Tragedy’ ever written. The particular joy in opera, he told me, isn’t the warbly voiced leading ladies, or the plump middle-aged romantic leads, or even the music. No, what packs the opera houses in Italy is the drama of characters who, by the very nature of their life-experiences and emotional baggage, make all sorts of bad choices when faced with ordinary decisions, and so move inexorably to their fate. The audience is gripped by the spectacle of exotic characters doomed by their inability to see the obvious. I confess, my personal experience with opera is limited to Bugs Bunny in “What’s Opera, Doc?” (Elmer Fudd is a great example of a bad decision maker, if ever one existed), but I was struck by my friend’s analogy. If all the DBA cubicles were a stage, I think we would hear many similarly tragic tales, played out to music: “Error handling? We write our code to never experience errors, so nah…“ “Backups failed today, but it’s okay, we’ll back up tomorrow (we’ll back up tomorrow)“ And similarly, they would leave their audience gasping, not necessarily at the beauty of the music, or poetry of the lyrics, but at the inevitable, grisly fate of the protagonists. If you choose not to use proper error handling, or if you choose to skip a backup because, hey, you haven’t had a server crash in 10 years, then inevitably, in that moment you expected to be enjoying a vacation, or a football game, with your family and friends, you will instead be sitting in front of a computer screen, paying for your poor choices. Tragedies are very much part of IT. Most of a DBA’s day to day work has limited potential to wreak havoc; paperwork, timesheets, random anonymous threats to developers, routine maintenance and whatnot. However, just occasionally, you, as a DBA, will face one of those decisions that really matter, and which has the possibility to greatly affect your future and the future of your user’s data. Make those decisions count, and you’ll avoid the tragic fate of many an operatic hero or villain.

  • Use Your Favorite Wallpapers in Windows 7 Starter Edition

    - by Asian Angel
    If you have Windows 7 Starter Edition installed on your netbook, the default wallpaper can get old. If you are tired of looking at the default wallpaper, then join us today as we look at changing it with Oceanis Change Background Windows 7. Special Notes This information is quoted directly from the website and needs to be kept in mind when using Oceanis Change Background Windows 7: If the Oceanis Change Background Windows 7 program no longer works properly after installing some Windows Updates, then uninstall and reinstall the Oceanis Change Background Windows 7 program to have it run properly again. If you ever do an in-place upgrade to another higher level edition of Windows 7 in the future, then be sure to uninstall this Oceanis Change Background Windows 7 program first to avoid incompatibility issues with it in the new edition of Windows 7. It was designed to only work in Windows 7 Starter edition. Before There it is…the default wallpaper everyone with the Starter Edition gets stuck with. Some people may not mind it, but if you are one of the people who really wants something different then get ready to rejoice. After The install file for Oceanis is contained in a zip file so you will need to unzip it to get started. The install process is quick and simple but you will need to do a system restart afterwards. Once you have restarted your computer this is what your screen will look like…do not panic and think that this is all there is to it. This is just the Starter Screen and can be easily changed… Note: Oceanis will auto-start with Windows each time. Using either the Desktop Icon or the Start Menu Entry, open up the Oceanis Main Window. You will see the set of four default wallpapers shown here. At this point the best thing to do is browse for the appropriate folder where you have all of those wonderful new wallpapers just waiting to be used. Note: We found Stretch to be the best Picture Position setting on our system. For our example we had three ready and waiting. We decided to try out the Wallpaper Slideshow feature first. We chose a time frame and saved our changes. Here are our three wallpapers as they switched through. This can be much more interesting than the default wallpaper. There was only one quirk that we encountered while using the Slideshow Setting. On occasion if we minimized a non-maximized window there would be a leftover partial image in place of the window. Our suggestion? Go with one wallpaper at a time and the settings shown below. These are the settings that we had terrific luck with…Only one picture selected, Picture Position = Stretch, & Change Picture Every = Every Day. Using these settings, the Starter Edition acted just like any of the other editions with regard to wallpaper management. Conclusion If you have grown tired of looking at the default wallpaper in Windows 7 Starter Edition then you will certainly appreciate what Oceanis Change Background Windows 7 can do to fix that problem.

This example will only work # if you are routing, not bridging, i.e. you are # using "dev tun" and "server" directives. # EXAMPLE: Suppose you want to give # Thelonious a fixed VPN IP address of 10.9.0.1. # First uncomment out these lines: ;client-config-dir ccd ;route 10.9.0.0 255.255.255.252 # Then add this line to ccd/Thelonious: # ifconfig-push 10.9.0.1 10.9.0.2 # Suppose that you want to enable different # firewall access policies for different groups # of clients.

  • Mind Reading with the Raspberry Pi

    - by speakjava
    Mind Reading With The Raspberry Pi At JavaOne in San Francisco I did a session entitled "Do You Like Coffee with Your Dessert? Java and the Raspberry Pi".  As part of this I showed some demonstrations of things I'd done using Java on the Raspberry Pi.  This is the first part of a series of blog entries that will cover all the different aspects of these demonstrations. A while ago I had bought a MindWave headset from Neurosky.  I was particularly interested to see how this worked as I had had the opportunity to visit Neurosky several years ago when they were still developing this technology.  At that time the 'headset' consisted of a headband (very much in the Bjorn Borg style) with a sensor attached and some wiring that clearly wasn't quite production ready.  The commercial version is very simple and easy to use: there are two sensors, one which rests on the skin of your forehead, the other is a small clip that attaches to your earlobe. Typical EEG sensors used in hospitals require lots of sensors and they all need copious amounts of conductive gel to ensure the electrical signals are picked up.  Part of Neurosky's innovation is the development of this simple dry-sensor technology.  Having put on the sensor and turned it on (it powers off a single AAA size battery) it collects data and transmits it to a USB dongle plugged into a PC, or in my case a Raspberry Pi. From a hacking perspective the USB dongle is ideal because it does not require any special drivers for any complex, low level USB communication.  Instead it appears as a simple serial device, which on the Raspberry Pi is accessed as /dev/ttyUSB0.  Neurosky have published details of the command protocol.  In addition, the MindSet protocol document, including sample code for parsing the data from the headset, can be found here. To get everything working on the Raspberry Pi using Java the first thing was to get serial communications going.  Back in the dim distant past there was the Java Comm API.  Sadly this has grown a bit dusty over the years, but there is a more modern open source project that provides compatible and enhanced functionality, RXTXComm.  This can be installed easily on the Pi using sudo apt-get install librxtx-java.  Next I wrote a library that would send commands to the MindWave headset via the serial port dongle and read back data being sent from the headset.  The design is pretty simple, I used an event based system so that code using the library could register listeners for different types of events from the headset.  You can download a complete NetBeans project for this here.  This includes javadoc API documentation that should make it obvious how to use it (incidentally, this will work on platforms other than Linux.  I've tested it on Windows without any issues, just by changing the device name to something like COM4). To test this I wrote a simple application that would connect to the headset and then print the attention and meditation values as they were received from the headset.  Again, you can download the NetBeans project for that here. Oracle recently released a developer preview of JavaFX on ARM which will run on the Raspberry Pi.  I thought it would be cool to write a graphical front end for the MindWave data that could take advantage of the built in charts of JavaFX.  Yet another NetBeans project is available here.  Screen shots of the app, which uses a very nice dial from the JFxtras project, are shown below. I probably should add labels for the EEG data so the user knows which is the low alpha, mid gamma waves and so on.  Given that I'm not a neurologist I suspect that it won't increase my understanding of what the (rather random looking) traces mean. In the next blog I'll explain how I connected a LEGO motor to the GPIO pins on the Raspberry Pi and then used my mind to control the motor!

  • Converting openGl code to DirectX

    - by Fredrik Boston Westman
    First of all, this is kind of a follow up question on @byte56 excellent anwser on this question concerning picking algorithms. I'm trying to convert one of his code examples to directX 11 however I have run in to some problems ( I can pick but the picking is way off), and I wanted to make sure I had done it rigth before moving on and checking the rest of my code. I am not that familiar with openGl but I can imagine openGl has diffrent coordinations systems, and functions that alters how you must implement to code abit. This is his code example: public Ray GetPickRay() { int mouseX = Mouse.getX(); int mouseY = WORLD.Byte56Game.getHeight() - Mouse.getY(); float windowWidth = WORLD.Byte56Game.getWidth(); float windowHeight = WORLD.Byte56Game.getHeight(); //get the mouse position in screenSpace coords double screenSpaceX = ((float) mouseX / (windowWidth / 2) - 1.0f) * aspectRatio; double screenSpaceY = (1.0f - (float) mouseY / (windowHeight / 2)); double viewRatio = Math.tan(((float) Math.PI / (180.f/ViewAngle) / 2.00f))* zoomFactor; screenSpaceX = screenSpaceX * viewRatio; screenSpaceY = screenSpaceY * viewRatio; //Find the far and near camera spaces Vector4f cameraSpaceNear = new Vector4f((float) (screenSpaceX * NearPlane), (float) (screenSpaceY * NearPlane), (float) (-NearPlane), 1); Vector4f cameraSpaceFar = new Vector4f((float) (screenSpaceX * FarPlane), (float) (screenSpaceY * FarPlane), (float) (-FarPlane), 1); //Unproject the 2D window into 3D to see where in 3D we're actually clicking Matrix4f tmpView = Matrix4f(view); Matrix4f invView = (Matrix4f) tmpView.invert(); Vector4f worldSpaceNear = new Vector4f(); Matrix4f.transform(invView, cameraSpaceNear, worldSpaceNear); Vector4f worldSpaceFar = new Vector4f(); Matrix4f.transform(invView, cameraSpaceFar, worldSpaceFar); //calculate the ray position and direction Vector3f rayPosition = new Vector3f(worldSpaceNear.x, worldSpaceNear.y, worldSpaceNear.z); Vector3f rayDirection = new Vector3f(worldSpaceFar.x - worldSpaceNear.x, worldSpaceFar.y - worldSpaceNear.y, worldSpaceFar.z - worldSpaceNear.z); rayDirection.normalise(); return new Ray(rayPosition, rayDirection); } All rigths reserved to him of course This is my DirectX 11 code : void GraphicEngine::pickRayVector(float mouseX, float mouseY,XMVECTOR& pickRayInWorldSpacePos, XMVECTOR& pickRayInWorldSpaceDir) { float PRVecX, PRVecY; float nearPlane = 0.1f; float farPlane = 200.0f; floar viewAngle = 0.4 * 3.14; PRVecX = ((( 2.0f * mouseX) / ClientWidth ) - 1 ) * tan((viewAngle)/2); PRVecY = (1-(( 2.0f * mouseY) / ClientHeight)) * tan((viewAngle)/2); XMVECTOR cameraSpaceNear = XMVectorSet(PRVecX * nearPlane,PRVecY * nearPlane, -nearPlane, 1.0f); XMVECTOR cameraSpaceFar = XMVectorSet(PRVecX * farPlane,PRVecY * farPlane, -farPlane, 1.0f); // Transform 3D Ray from View space to 3D ray in World space XMMATRIX invMat; XMVECTOR matInvDeter; invMat = XMMatrixInverse(&matInvDeter, cam->getCameraView()); //Inverse of View Space matrix is World space matrix XMVECTOR worldSpaceNear = XMVector3TransformCoord(cameraSpaceNear, invMat); XMVECTOR worldSpaceFar = XMVector3TransformCoord(cameraSpaceFar, invMat); pickRayInWorldSpacePos = worldSpaceNear; pickRayInWorldSpaceDir = worldSpaceFar-worldSpaceNear; pickRayInWorldSpaceDir = XMVector3Normalize(pickRayInWorldSpaceDir); } A couple of notes: The mouse coordinates are already converted so that the top left corner of the client window would be (0,0) and the bottom rigth (800,600) ( or whatever resolution you would have) I hadn't used any far or near plane before, so i just made some arbitrary number up for them. To my understanding it shouldnt matter as long as the object you are trying to pick is in between the range of thoese numbers The viewAngle is the same angle that I used when setting the camera view with XMMatrixPerspectiveFovLH , I just hadn't made it a member variable of my Camera class yet. I removed the variable aspectRation and zoomFactor because I assumed that they where related to some specific function of his game. Now I'm not sure, but I think the problems lies either withing the mouse to viewspace conversion, maby that we use diffrent coordinations systems. Either that or how i transform the matrixes in the the end, because i know order is important when it comes to matrixes. Any help is appriciated! Thanks in advance. Edit: One more note, my code is in c++

  • Windows 8 Camp&ndash;Ways to Prepare

    - by Lori Lalonde
    When Windows 8 was announced at the BUILD conference back in September, it created quite a buzz among the developer community. By the spring of 2012,  Windows 8 Developer Camps started popping up everywhere imaginable. I received a lot of questions from CTTDNUG members about whether or not we would be hosting one locally. If you recall my post about the Windows Phone/Azure Developer Workshop that CTTDNUG hosted back in March, you’ll remember that the biggest hurdle to overcome when planning this type of event was finding the right venue. It took some time, but I finally found a venue that was available and provided the prerequisites needed to ensure this camp is a success. I am very excited that CTTDNUG will be hosting a Windows 8 Camp this summer in the Kitchener/Waterloo area. In fact, it’s coming up in less than 2 weeks. Clearly other developers are excited as well, because our registration numbers show that the event is already 70% full! On top of that, I was fortunate enough to also book two well-known evangelists to present and teach at this full day developer camp: Andrei Marukovich and Atley Hunter. This was the icing on the cake. With the content provided by Microsoft, and two local experts that live and breathe Windows 8 development, I know that I, along with other developers that attend this event, will have the opportunity to maximize our learning potential and hit the ground running. If you plan on attending a Windows 8 Developer Camp soon, and want to ensure you get the most “bang for your buck” (figuratively speaking, since these camps are free), there are some things you can do to prepare before the big day: 1) Install the prerequisites on your own device before the big day I can’t stress this enough. Otherwise, you will be spending valuable time during the hands-on period downloading and installing what is needed, rather than digging into the development and using that time to ask the experts on-hand about programming challenges, issues, questions you may have with respect to your development. Prerequisites: Windows 8 Release Preview Visual Studio 2012 RC Download the Windows 8 SDK Samples 2) Purchase, download, and read Charles Petzold’s newest book:  Programming Windows 6th Edition This is a great introduction to the type of content you will be learning about during the camp. Doing some light reading beforehand might raise some questions about the concepts discussed in the book, which will give you the opportunity to write them down and bring them with you to the camp. The experts on hand will be able to answer them for you. 3) Make use of the freebies that are available Telerik has recently released a preview of their RadControls for Metro. You can sign up to receive a license code to give you access to install the preview for free and start playing around with it. Syncfusion also offers a free download of their Metro Studio package, which is a collection of metro style icons that you can customize and use in your own applications. Last but not least, once you’ve installed the Windows 8 Release Preview on your own device, go to the Windows 8 Store and download a handful of the free apps that are available. Testing out other Metro apps may give you ideas of what you can do in your own apps and analyze what features you like: application flow, type of animations used, concepts that were leveraged, how live tiles were used, etc. I hope you found these tips to be useful as you embark on a new development journey! Although this post focused on how to prepare for a Windows 8 camp, the same ideas are there whichever developer camp/workshop/event you attend. Learning does not begin and end on the day of the event. Attending a developer camp is just one step of many to master whatever technology you are interested in. It is a continuous process, which is fully maximized when you do your homework beforehand, actively participate during,  and follow up by putting what you learned to practice afterwards. Happy coding!

  • The SmartAssembly Rearchitecture

    - by Simon Cooper
    You may have noticed that not a lot has happened to SmartAssembly in the past few months. However, the team has been very busy behind the scenes working on an entirely new version of SmartAssembly. SmartAssembly 6.5 Over the past few releases of SmartAssembly, the team had come to the realisation that the current 'architecture' - grown organically, way before RedGate bought it, from a simple name obfuscator over the years into a full-featured obfuscator and assembly instrumentation tool - was simply not up to the task. Not for what we wanted to do with it at the time, and not what we have planned for the future. Not only was it not up to what we wanted it to do, but it was severely limiting our development capabilities; long-standing bugs in the root architecture that couldn't be fixed, some rather...interesting...design decisions, and convoluted logic that increased the complexity of any bugfix or new feature tenfold. So, we set out to fix this. Earlier this year, a new engine was written on which SmartAssembly would be based. Over the following few months, each feature was ported over to the new engine and extensively tested by our existing unit and integration tests. The engine was linked into the existing UI (no easy task, due to the tight coupling between the UI and old engine), and existing RedGate products were tested on the new SmartAssembly to ensure the new engine acted in the same way. The result is SmartAssembly 6.5. The risks of a rearchitecture Are there risks to rearchitecting a product like SmartAssembly? Of course. There was a lot of undocumented behaviour in the old engine, and as part of the rearchitecture we had to find this behaviour, define it, and document it. In the process we found some behaviour of the old engine that simply did not make sense; hence the changes in pruning & obfuscation behaviour in the release notes. All the special edge cases we had to find, document, and re-implement. There was a chance that these special cases would not be found until near the end of the project, when everything is functionally complete and interacting together. By that stage, it would be hard to go back and change anything without a whole lot of extra work, delaying the release by months. We always knew this was a possibility; our initial estimate of the time required was '4 months, ± 4 months'. And that was including various mitigation strategies to reduce the likelihood of these issues being found right at the end. Fortunately, this worst-case did not happen. However, the rearchitecture did produce some benefits. As well as numerous bug fixes that we could not fix any other way, we've also added logging that lets you find out exactly why a particular field or property wasn't pruned or obfuscated. There's a new command line interface, we've tested it with WP7.1 and Silverlight 5, and we've added a new option to error reporting to improve the performance of instrumented apps by ~10%, at the cost of inaccurate line numbers in reports. So? What differences will I see? Largely none. SmartAssembly 6.5 produces the same output as SmartAssembly 6.2. The performance of 6.5 will be much faster for some users, and generally the same as 6.2 for the remaining. If you've encountered a bug with previous versions of SmartAssembly, I encourage you to try 6.5, as it has most likely been fixed in the rearchitecture. If you encounter a bug with 6.5, please do tell us; we'll be doing another release quite soon, so we'll aim to fix any issues caused by 6.5 in that release. Most importantly, the new architecture finally allows us to implement some Big Things with SmartAssembly we've been planning for many months; these will fundamentally change how you build, release and monitor your application. Stay tuned for further updates!

  • Enterprise Integration: Can Companies Afford It?

    Each year, my company holds a global sales conference where employees and partners from around the world some together to collaborate, share knowledge and ideas and learn about future plans.  As a member of the professional services division, several of us had been asked to make a presentation, an elevator pitch in 3 minutes or less that relates to a success we have worked on or directly relates to our tag (that is, our primary technology focus).  Mine happens to be Enterprise Integration as it relates Business Intelligence.  I found it rather difficult to present that pitch in a short amount of time and had to pare it down.  At any rate, in just a little over 3 minutes, this is the presentation I submitted.  Here is a link to the full presentation video in WMV format.   Many companies today subscribe to a buy versus build mentality in an attempt to drive down costs and improve time to implementation. Sometimes this makes sense, especially as it relates to specialized software or software that performs a small number of tasks extremely well. However, if not carefully considered or planned out, this oftentimes leads to multiple disparate systems with silos of data or multiple versions of the same data. For instance, client data (contact information, addresses, phone numbers, opportunities, sales) stored in your CRM system may not play well with Accounts Receivables. Employee data may be stored across multiple systems such as HR, Time Entry and Payroll. Other data (such as member data) may not originate internally, but be provided by multiple outside sources in multiple formats. And to top it all off, some data may have to be manually entered into multiple systems to keep it all synchronized. When left to grow out of control like this, overall performance is lacking, stability is questionable and maintenance is frequent and costly. Worse yet, in many cases, this topology, this hodgepodge of data creates a reporting nightmare. Decision makers are forced to try to put together pieces of the puzzle attempting to find the information they need, wading through multiple systems to find what they think is the single version of the truth. More often than not, they find they are missing pieces, pieces that may be crucial to growing the business rather than closing the business. across applications. Master data owners are defined to establish single sources of data (such as the CRM system owns client data). Other systems subscribe to the master data and changes are replicated to subscribers as they are made. This can be one way (no changes are allowed on the subscriber systems) or bi-directional. But at all times, the master data owner is current or up to date. And all data, whether internal or external, use the same processes and methods to move data from one place to another, leveraging the same validations, lookups and transformations enterprise wide, eliminating inconsistencies and siloed data. Once implemented, an enterprise integration solution improves performance and stability by reducing the number of moving parts and eliminating inconsistent data. Overall maintenance costs are mitigated by reducing touch points or the number of places that require modification when a business rule is changed or another data element is added. Most importantly, however, now decision makers can easily extract and piece together the information they need to grow their business, improve customer satisfaction and so on. So, in implementing an enterprise integration solution, companies can position themselves for the future, allowing for easy transition to data marts, data warehousing and, ultimately, business intelligence. Along this path, companies can achieve growth in size, intelligence and complexity. Truly, the question is not can companies afford to implement an enterprise integration solution, but can they afford not to.   Ralph Wheaton Microsoft Certified Technology Specialist Microsoft Certified Professional Developer Microsoft VTS-P BizTalk, .Net

  • Using the Script Component as a Conditional Split

    This is a quick walk through on how you can use the Script Component to perform Conditional Split like behaviour, splitting your data across multiple outputs. We will use C# code to decide what does flows to which output, rather than the expression syntax of the Conditional Split transformation. Start by setting up the source. For my example the source is a list of SQL objects from sys.objects, just a quick way to get some data: SELECT type, name FROM sys.objects type name S syssoftobjrefs F FK_Message_Page U Conference IT queue_messages_23007163 Shown above is a small sample of the data you could expect to see. Once you have setup your source, add the Script Component, selecting Transformation when prompted for the type, and connect it up to the source. Now open the component, but don’t dive into the script just yet. First we need to select some columns. Select the Input Columns page and then select the columns we want to uses as part of our filter logic. You don’t need to choose columns that you may want later, this is just the columns used in the script itself. Next we need to add our outputs. Select the Inputs and Outputs page.You get one by default, but we need to add some more, it wouldn’t be much of a split otherwise. For this example we’ll add just one more. Click the Add Output button, and you’ll see a new output is added. Now we need to set some properties, so make sure our new Output 1 is selected. In the properties grid change the SynchronousInputID property to be our input Input 0, and  change the ExclusionGroup property to 1. Now select Ouput 0 and change the ExclusionGroup property to 2. This value itself isn’t important, provided each output has a different value other than zero. By setting this property on both outputs it allows us to split the data down one or the other, making each exclusive. If we left it to 0, that output would get all the rows. It can be a useful feature allowing you to copy selected rows to one output whilst retraining the full set of data in the other. Now we can go back to the Script page and start writing some code. For the example we will do a very simple test, if the value of the type column is U, for user table, then it goes down the first output, otherwise it ends up in the other. This mimics the exclusive behaviour of the conditional split transformation. public override void Input0_ProcessInputRow(Input0Buffer Row) { // Filter all user tables to the first output, // the remaining objects down the other if (Row.type.Trim() == "U") { Row.DirectRowToOutput0(); } else { Row.DirectRowToOutput1(); } } The code itself is very simple, a basic if clause that determines which of the DirectRowToOutput methods we call, there is one for each output. Of course you could write a lot more code to implement some very complex logic, but the final direction is still just a method call. If we now close the script component, we can hook up the outputs and test the package. Your numbers will vary depending on the sample database but as you can see we have clearly split out input data into two outputs. As a final tip, when adding the outputs I would normally rename them, changing the Name in the Properties grid. This means the generated methods follow the pattern as do the path label shown on the design surface, making everything that much easier to recognise.

  • Columnstore Case Study #1: MSIT SONAR Aggregations

    - by aspiringgeek
    Preamble This is the first in a series of posts documenting big wins encountered using columnstore indexes in SQL Server 2012 & 2014.  Many of these can be found in this deck along with details such as internals, best practices, caveats, etc.  The purpose of sharing the case studies in this context is to provide an easy-to-consume quick-reference alternative. Why Columnstore? If we’re looking for a subset of columns from one or a few rows, given the right indexes, SQL Server can do a superlative job of providing an answer. If we’re asking a question which by design needs to hit lots of rows—DW, reporting, aggregations, grouping, scans, etc., SQL Server has never had a good mechanism—until columnstore. Columnstore indexes were introduced in SQL Server 2012. However, they're still largely unknown. Some adoption blockers existed; yet columnstore was nonetheless a game changer for many apps.  In SQL Server 2014, potential blockers have been largely removed & they're going to profoundly change the way we interact with our data.  The purpose of this series is to share the performance benefits of columnstore & documenting columnstore is a compelling reason to upgrade to SQL Server 2014. App: MSIT SONAR Aggregations At MSIT, performance & configuration data is captured by SCOM. We archive much of the data in a partitioned data warehouse table in SQL Server 2012 for reporting via an application called SONAR.  By definition, this is a primary use case for columnstore—report queries requiring aggregation over large numbers of rows.  New data is refreshed each night by an automated table partitioning mechanism—a best practices scenario for columnstore. The Win Compared to performance using classic indexing which resulted in the expected query plan selection including partition elimination vs. SQL Server 2012 nonclustered columnstore, query performance increased significantly.  Logical reads were reduced by over a factor of 50; both CPU & duration improved by factors of 20 or more.  Other than creating the columnstore index, no special modifications or tweaks to the app or databases schema were necessary to achieve the performance improvements.  Existing nonclustered indexes were rendered superfluous & were deleted, thus mitigating maintenance challenges such as defragging as well as conserving disk capacity. Details The table provides the raw data & summarizes the performance deltas. Logical Reads (8K pages) CPU (ms) Durn (ms) Columnstore 160,323 20,360 9,786 Conventional Table & Indexes 9,053,423 549,608 193,903 ? x56 x27 x20 The charts provide additional perspective of this data.  "Conventional vs. Columnstore Metrics" document the raw data.  Note on this linear display the magnitude of the conventional index performance vs. columnstore.  The “Metrics (?)” chart expresses these values as a ratio. Summary For DW, reports, & other BI workloads, columnstore often provides significant performance enhancements relative to conventional indexing.  I have documented here, the first in a series of reports on columnstore implementations, results from an initial implementation at MSIT in which logical reads were reduced by over a factor of 50; both CPU & duration improved by factors of 20 or more.  Subsequent features in this series document performance enhancements that are even more significant.

  • Framework 4 Features: Login Id Support

    - by Anthony Shorten
    Given that Oracle Utilities Application Framework 4 is available as part of Mobile Work Force Management and other product progressively I am preparing a number of short but sweet blog entries highlighting some of the new functionality that has been implemented. This is the first entry and it is on a new security feature called Login Id. In past releases of the Oracle Utilities Application Framework, the userid used for authentication and authorization was limited to eight (8) characters in length. This mirrored what the market required in the past with LAN userids and even legacy userids being that length. The technology market has since progressed to longer userid lengths. It is very common to hear that email addresses are being used as credentials for production systems. To achieve this in past versions of the Oracle Utilities Application Framework, sites had to introduce a short userid (8 characters in length) as an alias in your preferred security store. You then configured your J2EE Web Application Server to use the alias as credentials. This sometimes was a standard feaure of the security store and/or the J2EE Web Application Server, if you were lucky. If not, some java code has to be written to implement the solution. In Oracle Utilities Application Framework 4 we introduced a new attribute on the user object called Login Id. The Login Id can be up to 256 characters in length and is an alternative to the existing userid stored on the user object. This means the Oracle Utilities Application Framework can support both long and short userids. For backward compatibility we use the Login Id for authentication but the short userid for authorization and auditing. The user object within the Oracle Utilities Application Framework holds the translation. Backward compatibility is always a consideration in any of our designs for future or changed functionality. You will see reference to this fact in the blog entries I will be composing over the next few months. We have also thought about the flexibility in implementing this feature. The Login Id can be the same value of the Userid (the default for backward compatibility) or can be different. Both the Login Id and Userid have to be unique. This avoids sharing of credentials and is also backward compatible. You can manually enter the Login Id or provision it from Oracle Identity Manager (or other tool). If you use the Login Id only, then we will not autogenerate a short userid automatically as the rules for this can vary from site to site. You have a number of options there. Most Identity provisioning tools can generate a short userid at user creation time and this can be used. If you do not use provisioning tools, then you can write a class extension using the SDK to autoegenerate the userid based upon your sites preference. When we designed the feature there were lots of styles of generating userids (random, initial and surname, numbers etc). We could not really see a clear winner in that respect so we just allowed the extension to be inserted in if necessary. Most customers indicated to us that identity provisioning was the preferred way. This is why we released an Oracle Identity Manager integration with the framework. The Login id is case sensitive now which was not supported under userid. The introduction of the Login Id allows the product to offer flexible options when configuring security whilst maintaining backward compatibility.

  • Enjoy How-To Geek User Style Script Goodness

    - by Asian Angel
    Most people may not be aware of it but there are two user style scripts that have been created just for use with the How-To Geek website. If you are curious then join us as we look at these two scripts at work. Note: User Style Scripts & User Scripts can be added to most browsers but we are using Firefox for our examples here. The How-to Geek Wide User Style Script The first of the two scripts affects the viewing width of the website’s news content. Here you can see everything set at the normal width. When you visit the UserStyles website you will be able to view basic information about the script and see the code itself if desired. On the right side of the page is the good part though. Since we are using Firefox with Greasemonkey installed we chose the the “install as a user script option”. Notice that the script is available for other browsers as well (very nice!) Within a few moments of clicking on the “install as a user script button” you will see the following window asking confirmation for installing the script. After installing the user style script and refreshing the page it has now stretched out to fill 90% of the browser window’s area. Definitely nice! The How-To Geek – News and Comments (600px) User Style Script The second script can be very useful for anyone with the limited screen real-estate of a netbook. You can see another of the articles from here at the site viewed in a  “normal mode”. Once again you can view basic information about this particular user style script and view the code if desired. As above we have the Firefox/Greasemonkey combination at work so we installed as a user script. This is one of the great things about using Greasemonkey…it always checks with you to make certain that no unauthorized scripts are added. Once the script was installed and we refreshed the page things looked very very different. All the focus has been placed on the article itself and any comments attached to the article. For those who may be curious this is what the homepage looks like using this script. Conclusion If you have been wanting to add a little bit of “viewing spice” to your browser for the How-To Geek website then definitely pop over to the User Styles website and give these two scripts a try.

  • OpenGL not rendering my images to the screen

    - by Brendan Webster
    for some reason my game isn't showing the image I am rendering to the screen. My engine is state based, and at the beginning I set the logo, but it isn't showing on the screen. Here is my method of doing so first I create one image and assign some values to it's preset values. //create one image instance for the logo background O_File.v_Create_Images(1); //set the atributes of the background //first Image O_File.sImage[0].nImageDepth = -30.0f; O_File.sImage[0].sImageLocation = "image.bmp"; //load the images int O_File.v_Load_Images(); Then I load them with DevIL void C_File_Manager::v_Load_Images() { ilGenImages(1, &image); ilBindImage(image); for(int i = 0;i < sImage.size();i++) { success = ilLoadImage(sImage[i].sImageLocation.c_str()); if (success) { success = ilConvertImage(IL_RGBA, IL_UNSIGNED_BYTE); glGenTextures(1, &image); glBindTexture(GL_TEXTURE_2D, image); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, 4, ilGetInteger(IL_IMAGE_WIDTH), ilGetInteger(IL_IMAGE_HEIGHT), 0, ilGetInteger(IL_IMAGE_FORMAT), GL_UNSIGNED_BYTE, ilGetData()); //asign values to the width and height of the image if they are already not assigned if(sImage[i].nImageHeight == 0) sImage[i].nImageHeight = ilGetInteger(IL_IMAGE_HEIGHT); if(sImage[i].nImageWidth == 0) sImage[i].nImageWidth = ilGetInteger(IL_IMAGE_WIDTH); std::cout << sImage[i].nImageHeight << std::endl; const std::string word = sImage[i].sImageLocation.c_str(); std::cout << sImage[i].sImageLocation.c_str() << std::endl; ilLoadImage(word.c_str()); ilDeleteImages(1, &image); } } } and then I apply them to the screen void C_File_Manager::v_Apply_Images() { glMatrixMode(GL_MODELVIEW); glLoadIdentity(); for(int i = 0;i < sImage.size();i++) { //move the image to where it should be on the screen; glTranslatef(sImage[i].nImageX,sImage[i].nImageY,sImage[i].nImageDepth); //rotate image around the 3 axes glRotatef(sImage[i].fImageAngleX,1,0,0); glRotatef(sImage[i].fImageAngleY,0,1,0); glRotatef(sImage[i].fImageAngleZ,0,0,1); //scale the image glScalef(1,1,1); //center the image glTranslatef((sImage[i].nImageWidth/2),(sImage[i].nImageHeight/2),0); //draw the box that will encase the loaded image glBegin(GL_QUADS); //change the color of the loaded image; glColor4f(1,1,1,1); //top left corner of image glNormal3f(0.0,0,0.0); glTexCoord2f (1.0, 0.0); glVertex3f(0,0,sImage[i].nImageDepth); //top right corner of image glNormal3f(1.0,0,0.0); glTexCoord2f (1.0, 1.0); glVertex3f(0,sImage[i].nImageHeight,sImage[i].nImageDepth); //bottom right corner of image glNormal3f(-1.0,0,0.0); glTexCoord2f (0.0, 1.0); glVertex3f(sImage[i].nImageWidth,sImage[i].nImageHeight,sImage[i].nImageDepth); //bottom left corner of image glNormal3f(-1.0,0,0.0); glTexCoord2f(0.0, 0.0); glVertex3f(sImage[i].nImageWidth,0,sImage[i].nImageDepth); glEnd(); } } when I debug there is no errors at all, but yet the images don't show up on the screen, I have positioned the camera at (0,0,-1) and that is where the images should show up. the clipping plane is set 1 to 1000. There is probably some random problem with the code, but I just can't catch it.

  • HOWTO Turn off SPARC T4 or Intel AES-NI crypto acceleration.

    - by darrenm
    Since we released hardware crypto acceleration for SPARC T4 and Intel AES-NI support we have had a common question come up: 'How do I test without the hardware crypto acceleration?'. Initially this came up just for development use so developers can do unit testing on a machine that has hardware offload but still cover the code paths for a machine that doesn't (our integration and release testing would run on all supported types of hardware anyway).  I've also seen it asked in a customer context too so that we can show that there is a performance gain from the hardware crypto acceleration, (not just the fact that SPARC T4 much faster performing processor than T3) and measure what it is for their application. With SPARC T2/T3 we could easily disable the hardware crypto offload by running 'cryptoadm disable provider=n2cp/0'.  We can't do that with SPARC T4 or with Intel AES-NI because in both of those classes of processor the encryption doesn't require a device driver instead it is unprivileged user land callable instructions. Turns out there is away to do this by using features of the Solaris runtime loader (ld.so.1). First I need to expose a little bit of implementation detail about how the Solaris Cryptographic Framework is implemented in Solaris 11.  One of the new Solaris 11 features of the linker/loader is the ability to have a single ELF object that has multiple different implementations of the same functions that are selected at runtime based on the capabilities of the machine.  The alternate to this is having the application coded to call getisax() and make the choice itself.  We use this functionality of the linker/loader when we build the userland libraries for the Solaris Cryptographic Framework (specifically libmd.so, and the unfortunately misnamed due to historical reasons libsoftcrypto.so) The Solaris linker/loader allows control of a lot of its functionality via environment variables, we can use that to control the version of the cryptographic functions we run.  To do this we simply export the LD_HWCAP environment variable with values that tell ld.so.1 to not select the HWCAP section matching certain features even if isainfo says they are present.  For SPARC T4 that would be: export LD_HWCAP="-aes -des -md5 -sha256 -sha512 -mont -mpul" and for Intel systems with AES-NI support: export LD_HWCAP="-aes" This will work for consumers of the Solaris Cryptographic Framework that use the Solaris PKCS#11 libraries or use libmd.so interfaces directly.  It also works for the Oracle DB and Java JCE.  However does not work for the default enabled OpenSSL "t4" or "aes-ni" engines (unfortunately) because they do explicit calls to getisax() themselves rather than using multiple ELF cap sections. However we can still use OpenSSL to demonstrate this by explicitly selecting "pkcs11" engine  using only a single process and thread.  $ openssl speed -engine pkcs11 -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 54170.81k 187416.00k 489725.70k 805445.63k 1018880.00k $ LD_HWCAP="-aes" openssl speed -engine pkcs11 -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 29376.37k 58328.13k 79031.55k 86738.26k 89191.77k We can clearly see the difference this makes in the case where AES offload to the SPARC T4 was disabled. The "t4" engine is faster than the pkcs11 one because there is less overhead (again on a SPARC T4-1 using only a single process/thread - using -multi you will get even bigger numbers). $ openssl speed -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 85526.61k 89298.84k 91970.30k 92662.78k 92842.67k Yet another cool feature of the Solaris linker/loader, thanks Rod and Ali. Note these above openssl speed output is not intended to show the actual performance of any particular benchmark just that there is a significant improvement from using hardware acceleration on SPARC T4. For cryptographic performance benchmarks see the http://blogs.oracle.com/BestPerf/ postings.

  • SQL SERVER – Configuring Interactive Cleansing Suggestion Min Score for Suggestions in Data Quality Services (DQS) – Sensitivity of Suggestion

    - by pinaldave
    Earlier I talked about what kind of questions, I do not like when I get asked. Today we will go over the question which I like when I get asked the same. One of the reader practices various steps in my earlier blog post Step by Step Guide to Beginning Data Quality Services in SQL Server 2012 – Introduction to DQS. While reading the blog post he noticed that Data Quality Services is not providing very helpful suggestions. He wrote an email to me about it. Let us go over his email. “Pinal, I noticed in one of your images that DQS is not providing very helpful suggestions. First of all DQS should be able to make intelligent guesses and make the necessary correction by itself. If it cannot do the same, in that case, it should give us intelligent suggestions but in the image included here, I see the suggestions are not there as well. Why is it so? Would you please tell me how to increase the numbers of suggestion? I do understand this may not be preferable solution in many case but all the business cases go on it depends. There are cases when the high sensitivity required and there are cases when higher sensitivities are not required. I would like to seek your help here. –Sriram MD” This is indeed a great question. I see that Sriram understands that every system is different and every application has a different need. I will not have to tell him this most important concept. The question is about how to change the sensitivity of suggestions for correction in DQS. Well, this option is available under the configuration tab in the DQS client. Once you click on Configuration you will see the following screen. Click the Tab of General Settings. You will see the section of Interactive Cleansing. Under this second there is the first option of “Min score for suggestions”. As this is set to 0.7 every suggestion which matches 0.7 probabilities or higher probability are displayed under the suggestion tab. You can see in the following image that there is no suggestion as the min score for suggestions is set to 0.7 and there is no record which qualifies to that much confidence. Now let us change the value of Min Score for suggestion to 0.5. The lower value increased the confidence of DQS to give further suggestion to values which are over 0.5. However, in our case the suggestions which it provides are also accurate. This may not be true for your sample. Every sample is different so you should manually review it before approving them. I guess, this is a simple blog post to demonstrate how to change the confidence value for the suggestions which Data Quality Services provides. Use this feature with care and always tune it according to your datasets and record diversity.

  • Determining explosion radius damage - Circle to Rectangle 2D

    - by Paul Renton
    One of the Cocos2D games I am working on has circular explosion effects. These explosion effects need to deal a percentage of their set maximum damage to all game characters (represented by rectangular bounding boxes as the objects in question are tanks) within the explosion radius. So this boils down to circle to rectangle collision and how far away the circle's radius is from the closest rectangle edge. I took a stab at figuring this out last night, but I believe there may be a better way. In particular, I don't know the best way to determine what percentage of damage to apply based on the distance calculated. Note : All tank objects have an anchor point of (0,0) so position is according to bottom left corner of bounding box. Explosion point is the center point of the circular explosion. TankObject * tank = (TankObject*) gameSprite; float distanceFromExplosionCenter; // IMPORTANT :: All GameCharacter have an assumed (0,0) anchor if (explosionPoint.x < tank.position.x) { // Explosion to WEST of tank if (explosionPoint.y <= tank.position.y) { //Explosion SOUTHWEST distanceFromExplosionCenter = ccpDistance(explosionPoint, tank.position); } else if (explosionPoint.y >= (tank.position.y + tank.contentSize.height)) { // Explosion NORTHWEST distanceFromExplosionCenter = ccpDistance(explosionPoint, ccp(tank.position.x, tank.position.y + tank.contentSize.height)); } else { // Exp center's y is between bottom and top corner of rect distanceFromExplosionCenter = tank.position.x - explosionPoint.x; } // end if } else if (explosionPoint.x > (tank.position.x + tank.contentSize.width)) { // Explosion to EAST of tank if (explosionPoint.y <= tank.position.y) { //Explosion SOUTHEAST distanceFromExplosionCenter = ccpDistance(explosionPoint, ccp(tank.position.x + tank.contentSize.width, tank.position.y)); } else if (explosionPoint.y >= (tank.position.y + tank.contentSize.height)) { // Explosion NORTHEAST distanceFromExplosionCenter = ccpDistance(explosionPoint, ccp(tank.position.x + tank.contentSize.width, tank.position.y + tank.contentSize.height)); } else { // Exp center's y is between bottom and top corner of rect distanceFromExplosionCenter = explosionPoint.x - (tank.position.x + tank.contentSize.width); } // end if } else { // Tank is either north or south and is inbetween left and right corner of rect if (explosionPoint.y < tank.position.y) { // Explosion is South distanceFromExplosionCenter = tank.position.y - explosionPoint.y; } else { // Explosion is North distanceFromExplosionCenter = explosionPoint.y - (tank.position.y + tank.contentSize.height); } // end if } // end outer if if (distanceFromExplosionCenter < explosionRadius) { /* Collision :: Smaller distance larger the damage */ int damageToApply; if (self.directHit) { damageToApply = self.explosionMaxDamage + self.directHitBonusDamage; [tank takeDamageAndAdjustHealthBar:damageToApply]; CCLOG(@"Explsoion-> DIRECT HIT with total damage %d", damageToApply); } else { // TODO adjust this... turning out negative for some reason... damageToApply = (1 - (distanceFromExplosionCenter/explosionRadius) * explosionMaxDamage); [tank takeDamageAndAdjustHealthBar:damageToApply]; CCLOG(@"Explosion-> Non direct hit collision with tank"); CCLOG(@"Damage to apply is %d", damageToApply); } // end if } else { CCLOG(@"Explosion-> Explosion distance is larger than explosion radius"); } // end if } // end if Questions: 1) Can this circle to rect collision algorithm be done better? Do I have too many checks? 2) How to calculate the percentage based damage? My current method generates negative numbers occasionally and I don't understand why (Maybe I need more sleep!). But, in my if statement, I ask if distance < explosion radius. When control goes through, distance/radius must be < 1 right? So 1 - that intermediate calculation should not be negative. Appreciate any help/advice!

  • Cellbi Silverlight Controls Giveaway (5 License to give away)

    - by mbcrump
    Cellbi recently updated their new Silverlight Controls to version 4 and to support Visual Studio 2010. I played with a couple of demos on their site and had to take a look. I headed over to their website and downloaded the controls. The first thing that I noticed was all of the special text effects and animations included. I emailed them asking if I could give away their controls in my January 2011 giveaway and they said yes. They also volunteered to give away 5 total license so the changes for you to win would increase.  I am very thankful they were willing to help the Silverlight community with this giveaway. So some quick rules below: ----------------------------------------------------------------------------------------------------------------------------------------------------------- Win a FREE developer’s license of Cellbi Silverlight Controls! (5 License to give away) Random winner will be announced on February 1st, 2011! To be entered into the contest do the following things: Subscribe to my feed. Leave a comment below with a valid email account (I WILL NOT share this info with anyone.) Retweet the following : I just entered to win free #Silverlight controls from @mbcrump and @cellbi http://mcrump.me/cscfree ! Don’t change the URL because this will allow me to track the users that Tweet this page. Don’t forget to visit Cellbi because they made this possible. ---------------------------------------------------------------------------------------------------------------------------------------------------------- Before we get started with the Silverlight Controls, here is a couple of links to bookmark: The What's new in this release page is here. You can also check out the live demos here. Don’t worry about the Samples/Help Documentation. That is installed to your local HDD during the installation process. Begin by downloading the trial version and running the program. After everything is installed then you will see the following screen: After it is installed, you may want to take a look at your Toolbox in Visual Studio 2010. After you add the controls from the “Choose Items” in Silverlight and you will see that you now have access to all of these controls. At this point, to use the controls it’s as simple as drag/drop onto your Silverlight container. It will create the proper Namespaces for you. It’s hard to show with a static screenshot just how powerful the controls actually are so I will refer you to the demo page to learn more about them. Since all of these are animations/effects it just doesn’t work with a static screenshot. It is worth noting that the Sfx pack really focuses on the following core effects: I will show you the best route to get started building a new project with them below. The best page to start is the sample browser which you can access by going to SvFx Launcher. In my case, I want to build a new Carousel. I simple navigate to the Carousel that I want to build and hit the “Cs” code at the top. This launches Visual Studio 2010 and now I can copy/paste the XAML into my project. That is all there is to it. Hopefully this post was helpful and don’t forget to leave a comment below in order to win a set of the controls!  Subscribe to my feed
