  • Interacting with scene from controller/app delegate cocos2d

    - by cjroebuck
    I'm attempting to make my first cocos2d (for iphone) multiplayer game and having difficulty understanding how to interact with a scene once it is running. The game is a simple turn-based one and so I have a GameController class which co-ordinates the rounds. I also have a GameScene class which is the actual scene that is displayed during a round of the game. The basic interaction I need is for the GameController to be able to pass messages to the GameScene class.. such as StartRound/StopRound etc. The thing that complicates this is that I am loading the GameScene with a LoadingScene class which simply initialises the scene and replaces the current scene with this one, so there is no reference from GameController to GameScene, so passing messages is quite tricky. Does anyone have any ways to get around this, ideally I would still like to use a Loading class as it smooths out the memory hit when replacing scenes.

If these components are not effectively shared by project leads and understood by stakeholders, project outcomes can be jeopardized and budgets may incur unnecessary risk. As reported by PMI’s 2013 Pulse of the Profession, an organization’s ability to meet project timelines, budgets and especially goals significantly impacts its ability to survive—and even thrive. The Pulse study revealed that the most crucial success factor in project management is effective communication to all stakeholders—a critical core competency for public agencies. PMI’s 2013 Pulse of the Profession report revealed that US$135 million is at risk for every US$1 billion spent on a project. Further research on the importance of effective project team communication uncovers that a startling 56 percent (US$75 million of that US$135 million) is at risk due to ineffective communication. Simply stated: public agencies cannot execute strategic initiatives unless they can effectively communicate their strategic alignment and business benefits. Executives and project managers around the world agree that poor communication between project team members contributes to project failure. A Forbes Insights 2010 Strategic Initiatives Study “Adapting Corporate Strategy to the Changing Economy,” found that nine out of ten CEOs believe that communication is critical to the success of their strategic initiatives, and nearly half of respondents cite communication as an integral and active component of their strategic planning and execution process. Project managers see it similarly from their side as well. According to PMI’s Pulse research, 55 percent of project managers agree that effective communication to all stakeholders is the most critical success factor in project management. As we all know, not all projects succeed. On average, two in five projects do not meet their original goals and business intent, and one-half of those unsuccessful projects are related to ineffective communication. Results reveal that while all aspects of project communication can be challenging to public agencies, the biggest problem areas are: A gap in understanding the business benefits. Challenges surrounding the language used to deliver project-related information, which is often unclear and peppered with project management jargon. Public agencies -- federal, state, and local -- have difficulty communicating with the appropriate levels with clarity and detail. This difficulty is likely exacerbated by the divide between each key audience and its understanding of project-specific, technical language. For those involved in public sector project and portfolio management, I would be interested to hear your thoughts and please visit Primavera EPPM solutions for public sector.

  • Does google contribute ranking from cdn.example.com to example.com?

    - by DesignerGuy
    Background From my understanding, http://mywebsite.com/image.jpg, can help the ranking of http://mywebsite.com in a search engine, such as Google (obviously the search engine of primary concern). So, SEO-wise, moving an image to http://whatever-cdn.com/my-account/image.jpg is bad. A popular solution is to use a CNAME record, such as http://cdn.mywebsite.com, so that image.jpg can be accessed at http://cdn.mywebsite.com/image.jpg. The question Does http://cdn.mywebsite.com/image.jpg rank as effectively as http://mywebsite.com/image.jpg ? Does it help boost the main http://mywebsite.com ? Or, does it rank independently because it is a subdomain? Is there another option (a way to use a CDN without sacrificing ranking)?

  • HTML5 article tag application for the iPad/iPhone

    - by dspencer
    I've used article tags on websites. My understanding and practice is to use the article tag for publication content. I always use HTML/HTML5 tags as their intended purposes and not at will. Recently, I've seen an HTML template that uses the article tag for the non-publication page content such as the content of an About Us page or any other generic page. I asked the why it was used this way and the (vague) explanation was that it had to do with the way the iPad read the tag. Is this true?

  • What is the most effective order to learn SQL Server, LINQ, and Entity Framework?

    - by user1525474
    I am trying to get some advice on what order I should learn about SQL Server, LINQ, and Entity Framework to be able to better work with ASP.NET Webforms and MVC. From what I've been able to learn so far, many recommend learning LINQ or Entity Framework before learning SQL Server. It also appears that many companies are looking for people with knowledge in LINQ-to-SQL and Entity Framework without mentioning SQL Server. However, my understanding is that LINQ-to-SQL and Entity Framework translate code into SQL Server queries, making this a poor approach. Is there a correct or best order in which to learn these technologies?

  • Not able to install ubuntu 12.10

    - by Janet
    When I try to install Ubuntu on my computer I get this error: /var/cache/apt/archives/compiz-gnome_1% 3a0.9.8.4+brz 3412-0ubuntu0.1_i386.deb and /var/cache/apt/archives/metacity-common_1% 3a2.34.8-0ubuntu4_all.deb Ok, since I'm not a whiz at installing linux or understanding it...When these two things popped up it stated that the file was corrupted and there were too many errors to complete the install. Now, does that help? I had Ubuntu 12.04 LTS on my computer and wanted to upgrade, now I have nothing on my desktop and when I tried to install by using my usb pen, nothing happen and I also have it on dvd and tried to install from that and nothing still happen. So maybe someone can tell me why it's not installing on my desktop? I have it on my laptop with Windows.

  • Healthcare Mobile Database Synchronization Demonstration

    - by Jim Connors
    Like many of you, I learn best by getting my hands dirty.  When confronted with the task of understanding a new set of products and technologies and figuring out how they might apply to a vertical industry like healthcare, I set out to create a demonstration.  The video that follows aims to show how the Oracle embedded software portfolio can be applied to a healthcare application.  The demonstration utilizes among others, Java SE Embedded, Berkeley DB, Apache Tomcat, Oracle 11gR2 and Oracle Database Mobile Server. Eric Jensen gives a great critique and description of the demo here.  To sum it up, we aim to show how live medical data can be collected on a medical device, stored in a local database, synchronized to a master database and furthermore propagated to a mobile phone (Android) application.  Come take a look!

  • When creating a new text file, should I add a .txt extension to its name?

    - by Agmenor
    When I create a new document aimed at containing only plain text, I am not obliged by Ubuntu to add a .txt extension to its name. It works indeed very well: gedit opens it without problem, understanding very well that it is only text. The only two pro arguments I have found from now on for adding an extension are 1/ interoperability with Windows systems and 2/ avoiding confusion with folders having the same name. Nevertheless those two arguments do not convince me at all. As a consequence, should I keep the reflex of adding an extension to files or not?

  • Is the copy/paste approach professionally viable when working with the Google Maps API?

    - by Ian Campbell
    I find that I understand much of the Javascript concepts used in the Google Maps API code, but then again there is quite a bit that is way over my head in syntax. For example, the geocoder syntax seems to be of Ajax form, though I don't understand what is happening under the hood (especially with lines like results[0].geometry.location). I am able to modify the body of if (status == google.maps.GeocoderStatus.OK) for different purposes though. So, being that I am able to take various code from the Developer's Guide and rework it to an extent for my own purposes, all the while not fully understanding what Google Maps is actually doing, does this make me a copy-paste programmer? Is this a bad practice, or is this professionally viable? I am, of course, interested in learning as much as I can, but what if time-constraints outweigh the learning process?

  • How does the "Fourth Dimension" work with arrays?

    - by Questionmark
    Abstract: So, as I understand it (although I have a very limited understanding), there are three dimensions that we (usually) work with physically: The 1st would be represented by a line. The 2nd would be represented by a square. The 3rd would be represented by a cube. Simple enough until we get to the 4th -- It is kinda hard to draw in a 3D space, if you know what I mean... Some people say that it has something to do with time. The Question: Now, that is all great with me. My question isn't about this, or I'd be asking it on MathSO or PhysicsSO. My question is: How does the computer handle this with arrays? I know that you can create 4D, 5D, 6D, etc... arrays in many different programming languages, but I want to know how that works.

  • How to avoid mediocre CV.

    - by QriousCat
    Though in every project we (testers) face different set challenges, when it comes to CV, more or less we have same responsibilities. For example responsibilities like understanding requirements, preparing and executing test cases, creating defects, liaising with dev, BA teams will be repeated for every project we involve. If we keep writing same responsibilities for every role, CV becomes mediocre and a yarn. In fact most of the testing resumes I have come across are like that. How do I avoid repetition of responsibilities in my resume and make it more interesting? If this is not the correct forum for this question let me know. Thanks in advance for your suggestions.

  • Choosing a crossplatform for mobile development

    - by Mech0z
    I am creating a enterprise project and will develop the app for WP, Android and IPhone (Maybe also tablets) I have then done some research of what solutions are out there and have narrowed my choice down to 3 platforms (Due to my requirement to work with Bluetooth) The biggest requirement other than Bluetooth is the need to create good interfaces and module programming so its easy to maintain the whole solution, other than that I would like to use C# but its not a real requirement, but if the difference between 2 platforms is very small then it might tip the scale. Mono (MonoTouch, Mono for android) PhoneGap RhoMobile From my understanding then PhoneGap is not suited for business apps and I am not entirely sure why, but it seems like a platform made for speed rather than long term developement, not sure how true this is. RhoMobile is made for enterprice and might suit my needs, but not sure if its a good platform Anyone with insight that care to share their opinion Mono is C#, seems to be very mature and I found MvvmCross which should help organize the project

  • What's the difference between stateful and stateless?

    - by Pankaj Upadhyay
    The books and documentation on the MVC just heap on using the Stateful and Stateless terms. To be honest, i am just unable to grab the idea of it, what the books are talking about. They don't give an example to understand any of the either state, rather than just telling that HTTP is stateless and with ASP.NET MVC microsoft is going along with it. Am I missing some fundamental knowledge, as i can't understand what is stateful and why is stateful and same goes for stateless. A simple and short example that talks about a control like button or textbox can be simplify the understanding i suppose.

  • What are Collaboration Data Objects (CDO)?

    - by Pranav
    Collaboration Data Objects or CDO, is a component that enables messaging between applications. It's something like the MFC we have in VC++ that enables us to prefer a simpler interface compared to the WIN32 API which, as an interface, still requires lots of escalation work by developers (yet very robust!). CDO is primarily built to simply the creations of messaging applications and we should keep in mind that CDO is NOT a new messaging model but is BUILT ON the MAPI architecture. It is just an extended interface that collaborates with MAPI and simplifies the programming task at hand for creation of messaging applications. CDO replaced Microsoft's earlier Active Messaging. CDO 1.2 enables us to play around with Data, send, receive emails and a host of other functions like rendering in exchange functionalities into HTML and do loads of other stuff. If you've got some firsthand experiences, a couple of tips will be great and will defiantly further my knowledge base in this area and hopefully get me a more refined understanding. Some pointers on MAPI will be pretty cool.

  • Do I need a wifi card to have internet access?

    - by Sarah
    I am attempting to set up a wireless network on 11.04, freshly download today. The router is on and working. However, I do not have a wifi "card" (which I am assuming is a little USB-type thing that allows internet access, but correct me if I am wrong) and every time I try to type in the MAC address and everything, nothing works. I also get the "firmware missing" error when I scroll over the signal strength, which I have tried looking up but have been unsuccessful with completely understanding it. I guess my main question is do I need another little device to be able to use wifi on my ubuntu? I do have an ethernet cable but another person is using it and I do not want to be tied down to that cable. the problem is that none of the wireless networks show up, however they show up when I go into Windows mode on my laptop. I get an error message at the top saying "firmware missing" which I have tried looking up but still have no straight answer for.

  • .mdf Database Filetype

    - by James Izzard
    Would somebody be kind enough to correct my understanding of the following (if incorrect)? Microsoft's .mdf file-type can be used by both the LocalDB and the full Server database engines (apologies if engine is not the correct word?). The .mdf file does not care which of these two options are accessing it - so you could use either to access any given .mdf file, provided you had permissions and password etc. The LocalDB and the SQL Server are two options that can be interchangeably chosen to access .mdf files depending on the application requirements. Appreciate any clarification. Thanks

  • How could a human factors degree help a computer scientist?

    - by Bob Dole
    I'm wrapping up a masters in CS and already have half the credit hours needed for a degree in Human Factors. I just recently discovered how useful understanding about cognition can help someone that creates user interfaces and am thirsty for more knowledge in the area. For me, it seems that having both a masters in Human Factors and CS would be very marketable but would there be jobs out there that would allow me to apply both? Meaning what I would really like to do is take the requirements for some application, apply different Human Factors theories( GOMS, CE+ ) to developing the interface, maybe do cognitive walk through with users to optimize the UI, then develop the application. Do jobs out there exist like this? The reason I ask, is because I'm wondering if most places just want you to be either a Human Factors Expert or a Developer but not both.

  • Some Insight on the Field of Knowledge Representations

    - by picmate
    I started following an MS in computer sciences after about two years of work for a software company. I worked primarily in data warehousing and business intelligence related software development during my previous occupation. There is a high chance for me to select a research in knowledge representations, ontologies and reasoning, as there are no other research available in any other interesting fields, such as pattern recognition and navigation. I developed an interest towards knowledge representation with what I learnt from the courses I am taking currently. But I do not have a deep understanding of it in terms of which areas such a field would have an impact in a real life scenario, and how it will help me when I am hunting for a job in the near future. Some thought about this would be greatly appreciated.

  • How to test robots.txt in googlebot to find out what is being indexed

    - by Amar Jarubula
    This question is a continuation for this answer How to check if googlebot will index a given url? As was told I did go to the Webmaster Tools and tested contents of my robots.txt file. However this is just giving me the info if that content is good enough or not. However for my scenario I need to test whether disallowing some patterns is being indexed or not. For example I have something like this below in my robots.txt disallow:/pattern* My understanding is the URLs with word pattern should not crawled, but how do I test this pattern is enforced while indexing the website?

  • Advice: How to overcome the "accent" barrier in cross-geographical teams ?

    - by shan23
    I'm an Indian working in a MNC. As a result, I often have to attend(and contribute) to meetings where I have to listen to people who have a pronounced American accent. Some are still understandable, but a couple of people I have interact with speak such a different form of English, I mostly have to guess at what they are saying. When I ask them to clarify, they often speak the same sentence in the same tenor/speed, so my net gain is zero. My question is, how to politely put it across that due to their accent, I can't understand a thing, and may they please speak slowly and a bit clearly ? Some people might take it a bit personally, since "everyone else" is understanding them perfectly...and I don't want to cause offense at all. Any ideas ?

  • Aren't there compilers better at telling the programmer what's wrong in a code ?

    - by jokoon
    I have worked a little while with the Microsoft compiler from Visual C++ but I worked a long time with G++, and I remember often having bad times understanding what was wrong in my code with the former. Beside binary code generation and optimisation, I think this is a very important feature of a C++ compiler: giving the programmer a clue that makes him understand as fast as possible what is wrong with his/her code. I can understand some programmers understand programming as some sort of "competition" to make less errors, but to me that's a counter productive opinion. I once tried Clang compiler for C from the LLVM thingie, I didn't use it for a long time, but I was impressed on how explicit and easy to understand the error messages were. What are your experiences, and how do you think this matters ? Some WIP of C++ Clang: http://clang.llvm.org/cxx_status.html

  • Are all languages basically the same?

    - by Anirudh
    Recently, i had to understand the design of a small program written in a language i had no idea about (ABAP, if you must know). I could figure it out without too much difficulty. I realize that mastering a new language is a completely different ball game, but purely understanding the intent of code (specifically production standard code, which is not necessarily complex) in any language is straight forward, if you already know a couple of languages (preferably one procedural/OO and one functional). Is this generally true? Are all programming languages made up of similar constructs like loops, conditional statements and message passing between functions? Are there non-esoteric languages that a typical Java/Ruby/Haskell programmer would not be able to make sense of? Do all languages have a common origin?
