  • Does it make the game more fun when the user is forced to progress through the levels sequentially rather than letting them pick and play?

    - by BeachRunnerJoe
    Hello. For the first time in my game, I'm stuck with a real design dilemma. I guess that's a good thing ;) I'm building a word puzzle game that has five levels, each with 30 puzzles. Currently, the user has to solve one puzzle at a time before moving to the next. However, I'm finding the user occasionally gets stuck on a puzzle, at which point they can no longer play until they solve it. This is obviously bad because many people will probably just quit playing the game and delete the app. The only elegant solution I can find to helping the player get unstuck is changing the design of the game to allow the users to pick any puzzle to play at any time. This way, if they get stuck, they can come back to it later and at least they have other puzzles to play in the meantime. It's my opinion, however, that this new flow design doesn't make the game as fun as the original flow design where the player has to complete a puzzle before moving to the next. To me, it's like anything else, when you only have one of something, it's more enjoyable, but when you have 30 of something, it's far less enjoyable. In fact, when I present the user with 30 puzzles to choose from, I'm concerned I might be making them feel like it's a lot of work they have to do and that's bad. I even had a tester voluntarily tell me that being forced to complete a puzzle before moving to the next is actually motivating. My questions are... Do you agree/disagree? Do you have any suggestions for how I can help the player get unstuck? Thanks so much in advance for your thoughts! EDIT: I should mention that I've already considered a few other solutions to helping the user get unstuck, but none of them seem like good ideas. They are... Add more hints: Currently, the user gets two hints per puzzle. If I increase the hint count, it only makes the game more easy and still leaves the possibility of the user getting stuck. Add a "Show Solution" button: This seems like a bad idea because it's my opinion this takes the fun out of the game for many people who would probably otherwise solve the puzzle if they didn't have the quick option to see the solution.

  • Writing a spell checker similar to "did you mean"

    - by user888734
    I'm hoping to write a spellchecker for search queries in a web application - not unlike Google's "Did you mean?" The algorithm will be loosely based on this: http://catalog.ldc.upenn.edu/LDC2006T13 In short, it generates correction candidates and scores them on how often they appear (along with adjacent words in the search query) in an enormous dataset of known n-grams - Google Web 1T - which contains well over 1 billion 5-grams. I'm not using the Web 1T dataset, but building my n-gram sets from my own documents - about 200k docs, and I'm estimating tens or hundreds of millions of n-grams will be generated. This kind of process is pushing the limits of my understanding of basic computing performance - can I simply load my n-grams into memory in a hashtable or dictionary when the app starts? Is the only limiting factor the amount of memory on the machine? Or am I barking up the wrong tree? Perhaps putting all my n-grams in a graph database with some sort of tree query optimisation? Could that ever be fast enough?

  • How do I install graphviz 2.29 in 12.04?

    - by bidur
    In my ubuntu 12.04, the graphviz is not the latest version(2.29). I need some features available in the latest version of graphviz. I tried to install the graphviz version 2.29, which requires libgraphviz4(=2.18). I anyhow installed libgraphviz4 and installed graphviz 2.29. For that I have to remove packages libcdt4 and libpathplan4. Now whenever I try to generate graph, I get some problems: For e.g.: dot -Kfdp -n -Tpng -o samplePOS.png forcePOS.dot It says: dot: error while loading shared libraries: libgvc.so.6: cannot open shared object file: No such file or directory neato -Tps -o sample_1.ps sourcedot.gv It says: neato: error while loading shared libraries: libgvc.so.6: cannot open shared object file: No such file or directory So, I am looking for some ways so that I can run graphviz 2.29 in my ubuntu 12.04.

  • Supermicro motherboards and systems

    - by jchang
    I used to buy SuperMicro exclusively for my own lab. SuperMicro always had a deep lineup of motherboards with almost every conceivable variation. In particular, they had the maximum memory and IO configuration that is desired for database servers. But from around 2006, I became too lazy to source the additional components necessary to complete the system, and switched to Dell PowerEdge Tower servers. Now, I may reconsider as neither Dell or HP are offering the right combination of PCI-E slots. Nor...(read more)

  • JCP.next.3: time to get to work

    - by Patrick Curran
    As I've previously reported in this blog, we planned three JSRs to improve the JCP’s processes and to meet our members’ expectations for change. The first - JCP.next.1, or more formally JSR 348: Towards a new version of the Java Community Process - was completed in October 2011. This focused on a small number of simple but important changes to make our process more transparent and to enable broader participation. We're already seeing the benefits of these changes as new and existing JSRs adopt the new requirements. However, because we wanted to complete this JSR quickly we deliberately postponed a number of more complex items, including everything that would require modifying the JSPA (the legal agreement that members sign when they join the organization) to a follow-on JSR. The second JSR (JSR 355: JCP Executive Committee Merge) is in progress now and will complete later this year. This JSR is even simpler than the first, and is focused solely on merging the two Executive Committees into one for greater efficiency and to encourage synergies between the Java ME and Java SE platforms. Continuing the momentum to move Java and the JCP forward we have just filed the third JSR (JCP.next.3) as JSR 358: A major revision of the Java Community Process. This JSR will modify the JSPA as well as the Process Document, and will tackle a large number of complex issues, many of them postponed from JSR 348. For these reasons we expect to spend a considerable amount of time working on it - at least a year, and probably more. The current version of the JSPA was created back in 2002, although some minor changes were introduced in 2005. Since then the organization and the environment in which we operate have changed significantly, and it is now time to revise our processes to ensure that they meet our current needs. We have a long list of topics to be considered, including the role of independent implementations (those not derived from the Reference Implementation), licensing and open source, ensuring that our new transparency requirements are implemented correctly, compatibility policy and TCKs, the role of individual members, patent policy, and IP flow. The Expert Group for JSR 358, as with all process-change JSRs, consists of all members of the Executive Committees. Even though the JSR has just been filed we started discussions on the various topics several months ago (see the EC's meeting minutes for details) and our EC members - including the new members who joined within the last year or two - are actively engaged. Now it's your opportunity to get involved. As required by version 2.8 of our Process (introduced with JSR 348) we will conduct all our business in the open. We have a public java.net project where you can follow and participate in our work. All of our deliberations will be copied to a public Observer mailing list, we'll track our issues on a public Issue Tracker, and all our documents (meeting agendas and minutes, task lists, working drafts) will be published in our Document Archive. We're just getting started, but we do want your input. Please visit us on java.net where you can learn how to participate. Let's get to work...

    I have been learning programming, mostly C# and .net stuff. And I have target to become a fulltime .NET developer. But I am feeling that learning Graph is very slow, I have been learning C# programming, doing some coding everyday, but how I can learn very fast and increase my skills rapidly? I know there should be a balance of coding and reading, as without reading I can't code and without coding I can't increase my skills. SO, I am requesting here suggesting from experts on how I bring more pace to my learning curve? I intend to give 4-6 hours daily for this and on weekends 10+ hours.

  • Separating merged array of arithmetic and geometric series [closed]

    - by user1814037
    Possible Duplicate: Separating merged array of arithmetic and geometric series My friend asked me an interseting question. Given an array of positive integers in increasing order. Seperate them in two series, an arithmetic sequence and geometric sequence. The given array is such that a solution do exist. The union of numbers of the two sequence must be the given array. Both series can have common elements i.e. series need not to be disjoint. The ratio of the geometric series can be fractional. Example: Given series : 2,4,6,8,10,12,25 AP: 2,4,6,8,10,12 GP: 4,10,25 I tried taking few examples but could not reach a general way. Even tried some graph implementation by introducing edges if they follow a particular sequence but could not reach solution.

  • MVVM and Animations in Silverlight

    - by Aligned
    I wanted to spin an icon to show progress to my user while some content was downloading. I'm using MVVM (aren't you) and made a satisfactory Storyboard to spin the icon. However, it took longer than expected to trigger that animation from my ViewModel's property.I used a combination of the GoToState action and the DataTrigger from the Microsoft.Expression.Interactions dll as described here.Then I had problems getting it to start until I found this approach that saved the day. The DataTrigger didn't bind right away because "it doesn’t change visual state on load is because the StateTarget property of the GotoStateAction is null at the time the DataTrigger fires.". Here's my XAML, hopefully you can fill in the rest.<Image x:Name="StatusIcon" AutomationProperties.AutomationId="StatusIcon" Width="16" Height="16" Stretch="Fill" Source="inProgress.png" ToolTipService.ToolTip="{Binding StatusTooltip}"> <i:Interaction.Triggers> <utilitiesBehaviors:DataTriggerWhichFiresOnLoad Value="True" Binding="{Binding IsDownloading, Mode=OneWay, TargetNullValue=True}"> <ei:GoToStateAction StateName="Downloading" /> </utilitiesBehaviors:DataTriggerWhichFiresOnLoad> <utilitiesBehaviors:DataTriggerWhichFiresOnLoad Value="False" Binding="{Binding IsDownloading, Mode=OneWay, TargetNullValue=True}"> <ei:GoToStateAction StateName="Complete"/> </utilitiesBehaviors:DataTriggerWhichFiresOnLoad> </i:Interaction.Triggers> <Image.Projection> <PlaneProjection/> </Image.Projection> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="VisualStateGroup"> <VisualStateGroup.Transitions> <VisualTransition GeneratedDuration="0" To="Downloading"> <VisualTransition.GeneratedEasingFunction> <QuadraticEase EasingMode="EaseInOut"/> </VisualTransition.GeneratedEasingFunction> <Storyboard RepeatBehavior="Forever"> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationZ)" Storyboard.TargetName="StatusIcon"> <EasingDoubleKeyFrame KeyTime="0:0:1.5" Value="-360"/> <EasingDoubleKeyFrame KeyTime="0:0:2" Value="-360"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </VisualTransition> <VisualTransition From="Downloading" GeneratedDuration="0"/> </VisualStateGroup.Transitions> <VisualState x:Name="Downloading"/> <VisualState x:Name="Complete"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups></Image>MVVMAnimations.zip

  • Understanding the SQL Server 2008 R2 Installation Center

    - by Enrique Lima
    What is available to us through those links?  Have you taken the time to explore and identify what could be useful to you? One of many gems that has come to my attention is the possibility of provisioning SQL Server to work in an image based environment (hint: Virtualization Template perhaps?!?).   Planning: Includes requirements information, documentation, how to guides, online documentation installation and other tools. Among the other tools you will find the System Configuration checker and The Upgrade Advisor. Both tools very important to ensure your deployment and installation would be successful.     Installation:  This sections focuses on getting installations going, from standalone to cluster when it comes to new instances.  Add new nodes to an existing cluster, and also perform upgrades (in this case to SQL Server 2008 R2).  Also part of this is the option to find updates available.   Maintenance: We find in this section, options that will assist us in tasks like repairing corrupt installations to removing nodes from a cluster. An option that is interesting (and we should discuss benefits later in another post) is to be able to do an Edition Upgrade, this is a feature expansion and addition based on your product installation (Developer to Enterprise, for example)   Tools:  From the System Configuration Checker to identify readiness for deployment in a successful manner, to being able to report on features installed.  And being able to run upgrades of existing packages developed in the 2005 offering to the 2008 R2 release for SSIS.   Resources: Useful and essential links to gather information and guidance.   Advanced: Here is where it gets interesting.  I break this down into 3 main groups: Installation Automation: When you install SQL Server there is a configuration file that gets dropped (ConfigurationFile.ini) that would allow for you to perform automated installations.  There are switches and options that go with this to have that process working. Cluster configuration for Sysprep: Create images that are cluster ready, 2 options, start the prep work, and then the complete once at the final destination. Stand-alone configuration for Sysprep:  Like the clustering counterpart, 2 options, prep and complete.  Giving you the option to create standard templates for your SQL Server deployments. I find it fitting that the 3 topics listed here should (and will) be additional topics I will discuss.   Options: Very clear and specific about what this means. Select the Processor Type or the Installation Media Root Path.
