• Stop Saying "Multi-Channel!"

  - by David Dorf

  I keep hearing the term "multi-channel" in our industry, but its time to move on. It kinda reminds me of the term "ECR" or electronic cash register. Long ago ECR was a leading-edge term, but nowadays its rarely used because its table-stakes. After all, what cash register today isn't electronic? The same logic applies to multi-channel, at least when we're talking about tier-1 and tier-2 retailers. If you're still talking about multi-channel retailing, you're in big trouble. Some have switched over to the term "cross-channel," and that's a step in the right direction but still falls short. Its kinda like saying, "I upgraded my ECR to accept debit cards!" Yawn. Who hasn't? Today's retailers need to focus on omni-channel, which I first heard from my friends over at RSR but was originally coined at IDC. First retailers added e-commerce to their store and catalog channels yielding multi-channel retailing. Consumers could use the channel that worked best for them. Then some consumers wanted to combine channels with features like buy-on-the-Web, pickup-in-the-store. Thus began the cross-channel initiatives to breakdown the silos and enable the channels to communicate with each other. But the multi-channel architecture is full of duplication that thwarts efforts of providing a consistent experience. Each has its own cart, its own pricing, and often its own CRM. This was an outcrop of trying to bring the independent channels to market quickly. Rather than reusing and rebuilding existing components to meet the new demands, silos were created that continue to exist today. Today's consumers want omni-channel retailing. They want to interact with brands in a consistent manner that is channel transparent, yet optimized for that particular interaction. The diagram below, from the soon-to-be-released NRF Mobile Blueprint v2, shows this progression. For retailers to provide an omni-channel experience, there needs to be one logical representation of products, prices, promotions, and customers across all channels. The only thing that varies is the presentation of the content based on the delivery mechanism (e.g. shelf labels, mobile phone, web site, print, etc.) and often these mechanisms can be combined in various ways. I'm looking forward to the day in which I can use my phone to scan QR-codes in a catalog to create a shopping cart of items. Then do some further research on the retailer's Web site and be told about related items that might interest me. Be able to easily solicit opinions and reviews from social sites, and finally enter the store to pickup my items, knowing that any applicable coupons have been applied. In this scenario, I the consumer are dealing with a single brand that is aware of me and my needs throughout the entire transaction. Nirvana.

• Suggestions for getting an open source electron beam tracking code going

  - by Boaz

  I work in the field of accelerator physics and synchrotron radiation. High energy electrons circulating in large rings of magnets produce x-rays that are used for a variety of different kinds of science. Running and improving these facilities requires controlling and modelling the electron beam as it circulates in the ring. A code to model this basically requires trackers to follow the electrons through the elements (something called a symplectic integrator), and then the computation of different parameters associated with this motion. The problem with these codes is that every facility has there own. In principle the code is not so complex. And as a modelling project, one might think it has some general interest. Who doesn't want to be able to create a track in space out of magnets and watch the electrons circulate? There is a Matlab based code to do this called Accelerator Toolbox, but the creator of the code is no longer in the field. I put the code in Sourceforge under the name atcollab. The basic resource is in C- it is the set of symplectic integrators. These are available in the atcollab code here. It has been useful to put the code on Sourceforge in order to exchange code, but the community of users is quite small and most are too busy to put that much time into collaboration. So in terms of really improving the code, I don't think it has been so successful. Any piece of this picture could be recreated without that much difficulty, but overall it is a bit complex, and because each lab has their own installation with lots of add-on Matlab code, people find it hard to really work together and share code. Somehow I think we need to involve a wider community in our development, or just use some standard tools. But for that, I suppose it needs to be of some general interest. I think symplectic integrators may have some general interest. And the part about a plug-in architecture to build up the ring ought to fit other patterns. Or the other option is to just accept that this is not a problem of general interest, and work harder within our small community. Suggestions, or anecdotes of analogous experience would be appreciated.

• Questions about game states

  - by MrPlow

  I'm trying to make a framework for a game I've wanted to do for quite a while. The first thing that I decided to implement was a state system for game states. When my "original" idea of having a doubly linked list of game states failed I found This blog and liked the idea of a stack based game state manager. However there were a few things I found weird: Instead of RAII two class methods are used to initialize and destroy the state Every game state class is a singleton(and singletons are bad aren't they?) Every GameState object is static So I took the idea and altered a few things and got this: GameState.h class GameState { private: bool m_paused; protected: StateManager& m_manager; public: GameState(StateManager& manager) : m_manager(manager), m_paused(false){} virtual ~GameState() {} virtual void update() = 0; virtual void draw() = 0; virtual void handleEvents() = 0; void pause() { m_paused = true; } void resume() { m_paused = false; } void changeState(std::unique_ptr<GameState> state) { m_manager.changeState(std::move(state)); } }; StateManager.h class GameState; class StateManager { private: std::vector< std::unique_ptr<GameState> > m_gameStates; public: StateManager(); void changeState(std::unique_ptr<GameState> state); void StateManager::pushState(std::unique_ptr<GameState> state); void popState(); void update(); void draw(); void handleEvents(); }; StateManager.cpp StateManager::StateManager() {} void StateManager::changeState( std::unique_ptr<GameState> state ) { if(!m_gameStates.empty()) { m_gameStates.pop_back(); } m_gameStates.push_back( std::move(state) ); } void StateManager::pushState(std::unique_ptr<GameState> state) { if(!m_gameStates.empty()) { m_gameStates.back()->pause(); } m_gameStates.push_back( std::move(state) ); } void StateManager::popState() { if(!m_gameStates.empty()) m_gameStates.pop_back(); } void StateManager::update() { if(!m_gameStates.empty()) m_gameStates.back()->update(); } void StateManager::draw() { if(!m_gameStates.empty()) m_gameStates.back()->draw(); } void StateManager::handleEvents() { if(!m_gameStates.empty()) m_gameStates.back()->handleEvents(); } And it's used like this: main.cpp StateManager states; states.changeState( std::unique_ptr<GameState>(new GameStateIntro(states)) ); while(gamewindow::gameWindow.isOpen()) { states.handleEvents(); states.update(); states.draw(); } Constructors/Destructors are used to create/destroy states instead of specialized class methods, state objects are no longer static but

• Android Swipe In Unity 3D World with AR

  - by Christian

  I am working on an AR application using Unity3D and the Vuforia SDK for Android. The way the application works is a when the designated image(a frame marker in our case) is recognized by the camera, a 3D island is rendered at that spot. Currently I am able to detect when/which objects are touched on the model by raycasting. I also am able to successfully detect a swipe using this code: if (Input.touchCount > 0) { Touch touch = Input.touches[0]; switch (touch.phase) { case TouchPhase.Began: couldBeSwipe = true; startPos = touch.position; startTime = Time.time; break; case TouchPhase.Moved: if (Mathf.Abs(touch.position.y - startPos.y) > comfortZoneY) { couldBeSwipe = false; } //track points here for raycast if it is swipe break; case TouchPhase.Stationary: couldBeSwipe = false; break; case TouchPhase.Ended: float swipeTime = Time.time - startTime; float swipeDist = (touch.position - startPos).magnitude; if (couldBeSwipe && (swipeTime < maxSwipeTime) && (swipeDist > minSwipeDist)) { // It's a swiiiiiiiiiiiipe! float swipeDirection = Mathf.Sign(touch.position.y - startPos.y); // Do something here in reaction to the swipe. swipeCounter.IncrementCounter(); } break; } touchInfo.SetTouchInfo (Time.time-startTime,(touch.position-startPos).magnitude,Mathf.Abs (touch.position.y-startPos.y)); } Thanks to andeeeee for the logic. But I want to have some interaction in the 3D world based on the swipe on the screen. I.E. If the user swipes over unoccluded enemies, they die. My first thought was to track all the points in the moved TouchPhase, and then if it is a swipe raycast into all those points and kill any enemy that is hit. Is there a better way to do this? What is the best approach? Thanks for the help!

• Data Auditor by Example

  - by Jinjin.Wang

  OWB has a node Data Auditors under Oracle Module in Projects Navigator. What is data auditor and how to use it? I will give an introduction to data auditor and show its usage by examples. Data auditor is an important tool in ensuring that data quality levels meet business requirements. Data auditor validates data against a set of data rules to determine which records comply and which do not. It gathers statistical metrics on how well the data in a system complies with a rule by auditing and marking how many errors are occurring against the audited table. Data auditors are typically scheduled for regular execution as part of a process flow, to monitor the quality of the data in an operational environment such as a data warehouse or ERP system, either immediately after updates like data loads, or at regular intervals. How to use data auditor to monitor data quality? Only objects with data rules can be monitored, so the first step is to define data rules according to business requirements and apply them to the objects you want to monitor. The objects can be tables, views, materialized views, and external tables. Secondly create a data auditor containing the objects. You can configure the data auditor and set physical deployment parameters for it as optional, which will be used while running the data auditor. Then deploy and run the data auditor either manually or as part of the process flow. After execution, the data auditor sets several output values, and records that are identified as not complying with the defined data rules contained in the data auditor are written to error tables. Here is an example. We have two tables DEPARTMENTS and EMPLOYEES (see pic-1 and pic-2. Click here for DDL and data) imported into OWB. We want to gather statistical metrics on how well data in these two tables satisfies the following requirements: a. Values of the EMPLOYEES.EMPLOYEE_ID attribute are three-digit numbers. b. Valid values for EMPLOYEES.JOB_ID are IT_PROG, SA_REP, SH_CLERK, PU_CLERK, and ST_CLERK. c. EMPLOYEES.EMPLOYEE_ID is related to DEPARTMENTS.MANAGER_ID. Pic-1 EMPLOYEES Pic-2 DEPARTMENTS 1. To determine legal data within EMPLOYEES or legal relationships between data in different columns of the two tables, firstly we define data rules based on the three requirements and apply them to tables. a. The first requirement is about patterns that an attribute is allowed to conform to. We create a Domain Pattern List data rule EMPLOYEE_PATTERN_RULE here. The pattern is defined in the Oracle Database regular expression syntax as ^([0-9]{3})$ Apply data rule EMPLOYEE_PATTERN_RULE to table EMPLOYEES.

• What are some good realistic programming related movies (docu-dramas, documentaries, accurate fiction, etc)?

  - by EpsilonVector

  A while ago I asked this question and the result was this. Following the response I got in the meta question I'm re-asking the question with new guidelines to focus it on the direction I wanted it to have originally. ================================================================== The guidelines are as follows: by "programming related" I mean movies from which we can learn about stuff like the development process, or history of software/computers, or programming culture. In other words, they must be grounded in the industry. No tangential stuff. Good entries answer as many of the following criteria as possible: Teach you about the history of the industry, or the development process, or teach you about important industry related topics (software patents for example) Are based on real life events, companies, people, practices, and they are the main focus of the movie After watching them, you feel like you understand or know something about the programmers' world that you didn't before (or you can see how someone could have such a response). You can point to it and say "this faithfully represents the industry/programmer culture at some point in time". This might be something you would show laymen to explain to them what "your people" are like and what is it that you do. Examples for good entries include: Pirates of Silicon Valley- the story of how Microsoft and Apple started the industry. Revolution OS- The story of Linux's rise to fame, and a pretty good cover of the Free Software/Open Source world. Aardvark'd: 12 Weeks with Geeks- development process. Examples for bad entries: Movies who's sole relevance is that they can be appreciated by programmers. The point of this question is not to be "what are some good movies" with "for a programmer" appended to it. Just because the writers got a few computer jokes right in itself doesn't make it about the industry. Movies where there's a computer related element, but are not about the industry. For example, 24 (the TV series). It's a product of the information age but it isn't actually about it. Another example is movies where there's a really cool programmer character, but are overall about something completely different. Likewise, The Big Bang Theory is not about physics, even though they have a cool physicist as a character. Science fiction, even if it draws ideas from computers. For example, the Matrix trilogy. Movies that you can't point to them and say: this is a faithful representation of our world (at some point in time). If you can't do that then it doesn't mirror the industry. Keep it one entry per answer so that the voting could sort the entries out.

• Height Map Mapping to "Chunked" Quadrilateralized Spherical Cube

  - by user3684950

  I have been working on a procedural spherical terrain generator for a few months which has a quadtree LOD system. The system splits the six faces of a quadrilateralized spherical cube into smaller "quads" or "patches" as the player approaches those faces. What I can't figure out is how to generate height maps for these patches. To generate the heights I am using a 3D ridged multi fractals algorithm. For now I can only displace the vertices of the patches directly using the output from the ridged multi fractals. I don't understand how I generate height maps that allow the vertices of a terrain patch to be mapped to pixels in the height map. The only thing I can think of is taking each vertex in a patch, plug that into the RMF and take that position and translate into u,v coordinates then determine the pixel position directly from the u,v coordinates and determine the grayscale color based on the height. I feel as if this is the right approach but there are a few other things that may further complicate my problem. First of all I intend to use "height maps" with a pixel resolution of 192x192 while the vertex "resolution" of each terrain patch is only 16x16 - meaning that I don't have any vertices to sample for the RMF for most of the pixels. The main reason the height map resolution is higher so that I can use it to generate a normal map (otherwise the height maps serve little purpose as I can just directly displace vertices as I currently am). I am pretty much following this paper very closely. This is, essentially, the part I am having trouble with. Using the cube-to-sphere mapping and the ridged multifractal algorithm previously described, a normalized height value ([0, 1]) is calculated. Using this height value, the terrain position is calculated and stored in the first three channels of the positionmap (RGB) – this will be used to calculate the normalmap. The fourth channel (A) is used to store the height value itself, to be used in the heightmap. The steps in the first sentence are my primary problem. I don't understand how the pixel positions correspond to positions on the sphere and what positions are sampled for the RMF to generate the pixels if only vertices cannot be used.

• Are there any drawbacks to the Major.Minor.YMDD.Build version strategy?

  - by Chu

  I'm trying to come up with a good version strategy to fit our specific needs. We've proposed settling on this and I wanted to ask the question to see if anyone's experience would suggest avoiding this or altering it in any way. Here's our proposal: Versions are released in this format: MAJOR.MINOR.YMDD.BN. Here it is broken out: MAJOR & MINOR are typical; we'll increase MINOR when we feel code and new feature sets warrants it; once every few months most likely. MAJOR will increase ~yearly. YMDD: Y will be the last digit of the current year, so "1" for 2011, "2" for 2012, etc. A non-padded month will be used to keep the number smaller (9 instead of 09 for example). DD of course is the day, padded with a zero for days under 10. BN: BN is the build number and increases by one anytime we make a change to a branch of the code represented by the build, for example: If were to make a build today, our release would be version 5.0.1707.1. I release to QA today and 3 days from now QA finds that a change broke the save functionality on a page. Instead of me changing our current development code, I'd go back to the code that I used to create version 5.0.1707.1, make the fix there, then increase the BN portion of the version and would then re-release 5.0.1707.2 back to QA. In short, anytime a change is made to a branched version that isn't the active dev branch, we'd use the original version number and increase only the BN portion (even if the change happened 3 days, 3 weeks or 3 months from the initial release of that version). Anytime we make a new release from our Active dev branch, we'd come up with a new version based on the M/D of the release using the outlined strategy. We do this once every 2-3 weeks. Are there holes or pitfalls with this? If so, what are they? Thanks EDIT To clarify one point that I didn't get out very well - Oct/Nov/Dec will be two digits, it's only the year that won't be. So 9 for Sept, 10 for Oct, 11 for Nov, etc.

• Oracle GoldenGate 11gR2 New Feature: Integrated Capture

Integrated capture is unique in the industry and unique to the Oracle database. It is not available on any other database platform. This new feature moves GoldenGate’s capture capabilities closer to the Oracle Database engine and is the foundation for Oracle GoldenGate on the Oracle Database platform over the long term. It is important to note that Integrated Capture does not replace our classic Capture process. Both are available on the Oracle Database platform. The Integrated Capture mechanism relies on Oracle’s internal log parsing and processing to capture DML transactions. By moving closer to the Oracle Database engine, Oracle GoldenGate can take advantage of new Oracle Database features and functionality more quickly. For example, this new mechanism allows GoldenGate to support advanced features such as compression. Integrated Capture provides support for all flavors of Oracle compression, including hybrid columnar compression (EHCC) on Exadata, where as our “Classic” capture would not. Integrated Capture supports two different deployment configurations; On-Source and Downstream. The on-source deployment model is what most customers are familiar with. Oracle GoldenGate is executing on the database server capturing changes in real time. This is the default deployment method. The other option is downstream, where the source database and the Oracle GoldenGate Capture process are on different machines. This method effectively off-loads the processing requirements to a second machine. Customers may choose which option they prefer based on their requirements.   Additional information on Integrated Capture can be found in our documentation and the white paper “Oracle GoldenGate for Oracle”.

• Correct way to handle path-finding collision matrix

  - by Xander Lamkins

  Here is an example of me utilizing path finding. The red grid represents the grid utilized by my A* library to locate a distance. This picture is only an example, currently it is all calculated on the 1x1 pixel level (pretty darn laggy). I want to make it so that the farther I click, the less accurate it will be (split the map into larger grid pieces). Edit: as mentioned by Eric, this is not a required game mechanic. I am perfectly fine with any method that allows me to make this accurate while still fast. This isn't the really the topic of this question though. The problem I have is, my current library uses a two dimensional grid of integers. The higher the number in a cell, the more resistance for that grid tile. Currently I'm setting all unwalkable spots to Integer Max. Here is an example of what I want: I'm just not sure how I should set up the arrays of integers of the grid. Every time an element is added/removed to/from the game, it's collision details are updated in the table. Here is a picture of what the map looks like on my collision layer: I probably shouldn't be creating new arrays every time I have to do a path find because my game needs to support tons of PF at the same time. Should I have multiple arrays that are all updated when the dynamic elements are updated (a building is built/a building is destroyed). The problem I see with this is that it will probably make the creation and destruction of buildings a little more laggy than I would want because it would be setting the collision grid for each built in accuracy level. I would also have to add more/remove some arrays if I ever in the future changed the map size. Should I generate the new array based on an accuracy value every time I need to PF? The problem I see with this is that it will probably make any form of PF just as laggy because it will have to search through a MapWidth x MapHeight number of cells to shrink it all down. Or is there a better way? I'm certainly not the best at optimizing really anything. I've just started dealing with XNA so I'm not used to having optimization code really doing much of an affect until now... :( If you need code examples, please ask. I'll add it as an edit. EDIT: While this doesn't directly relate to the question, I figure the more information I provide, the better. To keep your units from moving as accurately to the players desired position, I've decided that once the unit PFs over to the less accurate grid piece, it will then PF on a more accurate level to the exact position requested.

• Joomla Hide Menu Item, or: Using Rich Content as part of the navigation

  - by chiccodoro

  In my Joomla based web site, I have a two layer main menu. The page layout contains two sections whereas the left one displays the content and the right one displays some other kind of content which at the same time serves as a menu. For example, if the user clicks on the "Products" - "SomeCategory" 2nd level menu item, the left section displays an image. The right section lists all products of that category. Each product is represented by an image and text. The content is scrollable. This section is implemented by means of a custom module (mod_custom) assigned to the menu. The content is rich text (HTML). Each product is entered manually by adding a picture and a text in the WYSIWYG editor, and by inserting a link for the picture and text. Now the issue: When the user clicks on a product, I want to display the corresponding product description article ("SomeProduct") to the left, accounting for the following requirements: The bread crumb now displays "Products - SomeCategory - SomeProduct" The main menu still displays the 2nd level for "Products", and "SomeCategory" is still marked as selected. (I would love if the right section which lists the product would remain in the exact same scroll state, but that's a completely different story.) If I link the product entry from the right hand side directly to the article "SomeProduct", then the article appears to the left, but the breadcrumb and menu are reset. So I wanted to create a hidden menu item "SomeProduct" beneath "SomeCategory", and to link the product entry to that menu item. This way, if I click on the product entry, the article appears to the left, the breadcrumb behaves correctly, and the menu state is preserved. However, it is not possible to configure the SomeProduct menu item as "hidden", therefore it appears in the main menu. I found some resources that suggest to create another menu, called "hidden", which does not use any modules, and to create the "SomeProduct" menu item in that menu. Unfortunately this did not work for me: If I link that menu item from the product entry, and click on that entry, then the article appears to the left, but the menu is reset, and the breadcrumb displays "SomeProduct" instead of "Products SomeCategory SomeProduct". Lucky me! I found an appropriate stackexchange site where I can pour out my heart to you guys. Sure you can help me :-)

• #SSAS #Tabular Workshop and Community Events in Netherlands and Denmark

  - by Marco Russo (SQLBI)

  Next week I will finally start the roadshow of the SSAS Tabular Workshop, a 2-day seminar about the new BISM Tabular model for Analysis Services that has been introduced in SQL Server 2012. During these roadshows, we always try to arrange some speeches at local community events in the evening - we already defined for Copenhagen, we have some logistic issue in Amsterdam that we're trying to solve. Here is the timetable: Netherlands SSAS Workshop in Amsterdam, NL – April 16-17, 2012 2-day seminar, I and Alberto will be the trainers for this event, register here We're trying to manage a Community event but we still don't have a confirmation, stay tuned        Denmark SSAS Workshop in Copenhagen, DK – April 26-27, 2012 2-day seminar, I and Alberto will be the trainers for this event, register here Community event on April 26, 2012 This event will run in Hellerup, at Microsoft venue All details available here: http://msbip.dk/events/26/msbip-mode-nr-5/ People from Sweden are welcome! Just register to this private group on LinkedIn in order to announce your presence, so we’ll know how many people will attend In community events we’ll deliver two speeches – here are the descriptions: Inside xVelocity (VertiPaq) PowerPivot and BISM Tabular models in Analysis Services share a great columnar-based database engine called xVelocity in-memory analytics engine (VertiPaq). If you want to improve performance and optimize memory used, you have to understand some basic principles about how this engine works, how data is compressed, and how you can design a data model for better optimization. Prepare yourself to change your mind. xVelocity optimization techniques might seem counterintuitive and are absolutely different than OLAP and SQL ones! Choosing between Tabular and Multidimensional You have a new project and you have to make an important decision upfront. Should you use Tabular or Multidimensional? It is not easy to answer, because sometime there is a clear choice, but most of the times both decisions might be correct, at least at the beginning. In this session we’ll help you making an informed decision, correctly evaluating pros and cons of each one according to common scenarios, considering both short-term and long-term consequences of your choice. I hope to meet many people in this first dates. We have many other events coming in May and June, including an online event (for US time zones), and you can also attend our PreCon Day at TechEd US in Orland (PRC06) or TechEd Europe in Amsterdam. I’ll be a good customer for airline companies in the next three months! I’m just sorry that I hadn’t time to write other articles in the last month, but I’m accumulating material that I will need to write down during some flight – stay tuned…

• How to wrap console utils in webserver

  - by Alex Brown

  I have a big dataset (100Mbs/day) and a bunch of console a TCL/TK tools to view it - I want to turn it into a web app that I can build, and others can maintain. In long: my group runs simulations yielding 100s of Mbs of data daily, in multiple (mostly but not only) text forms. We have a bunch of scripts and tools, mostly old school 1990's style stuff requiring a 5-button mouse, as well as lots of ad-hoc scripts that engineers build out of frustration every month or so. These produces UIs, graphs, spreadsheets (various sizes), logs, event histories etc. I want to replace (or at least supplement) the xwindows / console style UI with a web-based one, so I need the following properties: pleasant to program can wrap existing command-line tools in separate views (I don't need to scrape GUIs or anything) as I port logic from the existing scripts I can create a modularised and pleasant codebase to replace it I can attach a web-ui to navigate between views - each view is likely to contain keys which might make sense to view in another I am new to building systems that have logic on the back-end and front-end of a web-server. from that point of view, they do this: backend wraps old-school executables, constructs calls into them and them takes the output and wraps it up, niceifies it and delivers it to the web client. For instance the tool might generate a number of indexed images (per invocation) which I might deliver all at once or on-demand. May (probably) need to to heavy stats on some sources. frontend provides navigation connecting multiple views, performs requests from one view for data from another (or self to self), etc. Probably will have some views with a lot of interactivity. Can people please point me towards viable solutions for this? I know it's a bit of an open question so as answers come in I hope to refine the spec until we have a good match. I guess I expect to see answers like "RoR!" "beans!" "Scala!" but please give an indication of why those are a good fit; I know nothing! I got bumped off SO for asking an open-ended question, so sorry if its OT here too (let me know). I take the policy that I use the best/closest matched language for a project but most of my team are extremely low level (ie pipeline stages and CDyn) so I don't have the peer group to know where to start.

• How can I dynamically load the correct sprite from a sprite sheet?

  - by Leonard Challis

  I am making a simple card game in unity. The game is based on a standard 52-card pack, with identical backs for unique faces. In my particular game different cards are worth different values and have various special abilities. The game will have 52 cards on the table (on the draw position or in the face-down deck or in someone's hand) at all times, so this number won't change. I thought that making a Card prefab and instantiating 52 of these manually would be a bad idea. Even doing it in code, I thought, would be a bit OTT, and that I should just instantiate visual cards when they are face-up to the player. I have a sprite sheet of the 52 cards and the back, which is imported as a Sprite in multiple mode, sliced in to a grid containing all the cards needed to play the game. The problem I now face is that, through my GameController script I want to generate a shuffled pack of cards, deal some to each player and then show those cards to a player. However, I am not sure of the best way, or even if it's possible, to do this dynamically with the sprite sheets as they are. For instance if I have the following: private CardRank rank; private CardSuite suite; private void Start() { this.rank = CardRank.Ace; this.suite = CardSuite.Spades; } This class would be instantiated by the game manager. I would have 52 of these in code. Whenever I have to visually show a card in the scene, I would use a card prefab, which is essentially a game object with a SpriteRenderer on it. I would need to dynamically load the correct sprite for this object from the spritesheet. The sliced sprites from the sprite sheet actually have names in the format AS (Ace of Spades), 7H (Seven of Hearts), etc - though this was a manual thing I did myself of course. I have also tried various alternative solutions, including creating animations, having separate sprites not in a spritesheet and having an array of available sprites in an array with a specific index for each card, but none seem as elegant as trying to load the correct sprite at runtime, as I'm trying to. So, how do I load a specific sprite from a spritesheet at runtime? I'm open to suggestions, even those that make me think differently about how to approach the problem.

• Code Analysis Rule Sets in Visual Studio 2010

  - by Anthony Trudeau

  Microsoft Visual Studio 2010 introduces the concept of rule sets when configuring code analysis.  This is a valuable change from Visual Studio 2008 that I didn't even realize I wanted.  Visual Studio 2008 by default selected all rules and then you had to remove rules on an item by item basis. The rule sets fall into logical groups including "Microsoft All Rules", "Microsoft Basic Correctness Rules", "Microsoft Security Rules", et al.  And within the project properties you can select one rule set, multiple rule sets, or you can define your own rule set based upon another. Selecting a single rule set is obviously the easiest option.  The default rule set when you create a new project is the "Microsoft Minimum Recommended Rules".  However, in my opinion the recommended rules are just too permissive.  For that reason you might want to change your rule set to "Microsoft All Rules" until you get around to creating your own rule set; or alternately you can select multiple rule sets which is an option from the rule set combo box.  The Visual Studio documentation has comprehensive help on what is contained within the rule sets. Creating your own rule set is easy if not obvious.  You need to start a rule set from an existing rule set.  To get started select a rule set in the combo box within the Code Analysis tab of the project properties.  I selected the "Microsoft All Rules" for my rule set, but you may find it easier to start with the "Microsoft Minimum Recommended Rules" if your rules are on the more permissive side. Once your rule set is selected click the Open button.  This will display a dialog that is similar in composition to the rules selection from Visual Studio 2008.  Browsing through the tree view you can select or deselect individual rules within their categories; and you can indicate that the rules are flagged as errors instead of the default which is a warning.  A nice touch to the form is that you get a help pane when you select an individual rule.  That helped me considerably when I first configured my rule set. Once you have finished selecting your rules click the Save tool button, specify a location and name, and click the Save button on the Save As dialog.  Once you're back on the Code Analysis tab you'll choose the Browse option within the combo box and open the file you just created.

• Start Time & Calculated Column Wonkiness in a SharePoint Event Calendar

  - by _zekeMouseOver

  I was creating some custom rollups on some of our event calendars and came across a very odd bug when trying to grab only the date component of the built-in Start Time field. One's first inclination will be to create a calculated column and give it the formula... =[Start Time]... and then assign its output type to be "Date Only." This works well until a user adds an All Day Event. For reasons unexplainable, the All Day Event flag causes your =[Start Time] to display the date minus one day. Here is an example of this in action:  Start Date and Time, Duration, Start Date Value and Start Day are all calculated fields. Notice how the Start Date and Time (=[Start Time]) is reporting 6:00PM of the previous day. The Start Date Value (=[Start Time] - Output Type: Number) confirms this (.75 = 6:00 PM.) Curiously enough, the Duration (=[End Time]-[Start Time]) is properly reporting the duration between 12:00AM and 11:59PM. Why? I don't know. Perhaps it's somehow bound to the regional settings on the site, but I'm not interested in changing a global site setting for the sake of one calculated field.With this information at our disposal, our calculated column to display the date part of the start date needs to be modified to add one day to the [Start Time] field if an All Day Event is selected. To determine this, we use the Duration above to assume the item is an all-day event and change our formula to be:=IF(TEXT(([End Time]-[Start Time])-TRUNC(([End Time]-[Start Time]),0),"0.000000000")="0.999305556",[Start Time] + 1, [Start Time])This will work, but what happens when the user de-selects the "All Day Event" checkbox? The duration stays the same, but all other values begin reporting the correct time: Since our formula above is strictly based on an expected duration, it will add one to the correct date, causing the date 5/11/2010 to appear. Notice though that the raw value of the start time (in this case) is a non-fractional number (40,308) whereas the all-day event was being represented as 6:00 PM (.75) of the previous day. We can use this to add one more nested branch of logic to our calculation:=IF(TEXT(([End Time]-[Start Time])-TRUNC(([End Time]-[Start Time]),0),"0.000000000")="0.999305556",IF([Start Time]=ROUND([Start Time],0),[Start Time],[Start Time]+1),[Start Time]) I feel somewhat... dirty about having to resort to this kind of calculation in what SHOULD have been a simple =[Start Time] to extract the date part of the Start Time field, but there you have it. Make sure to shower extra longer after having used it.

• Telesharp – An Application Repository for .NET applications

  - by cibrax

  A year ago, we released SO-Aware as our first product in Tellago Studios. SO-Aware represented a new way to manage web services and all the related artifacts like configuration, tests or monitoring data in the Microsoft stack. It was based on the idea of using a lightweight SOA governance approach with a central repository exposed through RESTful services. At that point, we thought the same idea could be extended to enterprise applications in general by providing a generic repository for many of the runtime or design time artifacts generated during the development like configuration, application description or topology (a high level view of the components that made up a system), logging information or binaries. It took us several months to give a form to that idea and implement it as a product, but it is finally here and I am very proud to announce the release today under the name of “TeleSharp”. Telesharp provides in a nutshell the following features, 1. Configure your application topology in a central repository. Application topology in this context means that you can decompose your application and describe it in terms of components and how they interact each other. For example, you can tell that the CRM system is made up of a couple of WCF services and a ASP.NET MVC front end. 2. Centralize configuration for your applications and components.  You can import existing .NET configuration sections into the repository and associate them to the different components. In addition, environment overrides are supported for the configuration sections. We provide tooling and extensions in Visual Studio for managing all the configuration, and a set of powershell commands for automating the configuration deployment. 3. Browse all the assemblies and types remotely in your application servers in a web browser using an interface similar to any of the existing .NET reflection tools. You can easily determine this way whether the server is running the correct version of your applications. 4. Centralize logging and exception management into the repository. You get different reports and a pivot viewer experience for browsing all the different logging information generated by your applications. In addition, TeleSharp provides different providers for pushing the logging information to the central repository using well-known frameworks like ELMAH, Log4Net, EntLib or even Windows ETW.  The central repository itself is implemented as a set of OData services that any application can easily consume using regular Http. You can read more details in this introductory post If you think this product can be a good fit in your organization, you can request a trial version in our Tellago Studios website.

• What is the rationale behind snazzy Window Managers/Composers?

  - by Emanuele

  This is more of a generic question, based on trying out Window Managers like Awesome, Mate and others. To me looks like that other Window Managers like Gnome3 and/or Unity are heavy and pointless. I do understand that having all the composed UIs is more pleasant for the eye, but apart that, what are the other major benefits? To make an example, when I run the game Heroes of Newerth (using nVidia drivers) under: Unity : the FPS drops sharply Gnome3 : FPS is ok, but X and other processes use 15~20% of CPU and quite some additional memory Awesome : FPS is ok, and other processes use very little memory and CPU Below some numbers regarding what I'm saying (please note my system is 64 bit, AMD Phenom II X4, 8 GB RAM, nd nVidia 470 GTX, SSD disk). All data is sorted by mem usage (watch -d -n 10 "ps -e -o pcpu,pmem,pid,user,cmd --sort=-pmem | head -20"); again note that CPU time of ./hon-x86_64 might be different due to the fact I can't take the snapshot of the system during exactly same time. Awesome: %CPU %MEM PID USER CMD 91.8 21.6 3579 ema ./hon-x86_64 2.4 0.9 3223 root /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch 1.6 0.4 2600 ema /usr/lib/erlang/erts-5.8.5/bin/beam.smp -Bd -K true -A 4 -- -root /usr/lib/erlang -progname erl -- -home /home/ema -- -noshell -noinp 0.3 0.2 3602 ema gnome-terminal 0.0 0.2 2698 ema /usr/bin/python /usr/lib/desktopcouch/desktopcouch-service Gnome3: %CPU %MEM PID USER CMD 82.7 21.0 5528 ema ./hon-x86_64 17.7 1.7 5315 ema /usr/bin/gnome-shell 5.8 1.2 5062 root /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch 1.0 0.4 5657 ema /usr/bin/python /usr/lib/ubuntuone-client/ubuntuone-syncdaemon 0.7 0.3 5331 ema nautilus -n 1.6 0.3 2600 ema /usr/lib/erlang/erts-5.8.5/bin/beam.smp -Bd -K true -A 4 -- -root /usr/lib/erlang -progname erl -- -home /home/ema -- - 0.9 0.2 5451 ema gnome-terminal 0.1 0.2 5400 ema /usr/bin/python /usr/lib/desktopcouch/desktopcouch-service Unity 3D: %CPU %MEM PID USER CMD 87.2 21.1 6554 ema ./hon-x86_64 10.7 2.6 6105 ema compiz 17.8 1.1 5842 root /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch 1.3 0.9 6672 root /usr/bin/python /usr/sbin/aptd 0.4 0.4 6606 ema /usr/bin/python /usr/lib/ubuntuone-client/ubuntuone-syncdaemon 0.5 0.3 6115 ema nautilus -n 1.5 0.3 2600 ema /usr/lib/erlang/erts-5.8.5/bin/beam.smp -Bd -K true -A 4 -- -root /usr/lib/erlang -progname erl -- -home /home/ema -- -noshell -noinput -sasl errl 0.3 0.2 6180 ema /usr/lib/unity/unity-panel-service So my point is, what's the rationale behind going towards such heavy WMs/Composers?

• Phone number in meta description bad or good for local rankings NAP

  - by bybe

  Once again I'm at it with increasing people's local rankings and I've learnt so much about local rankings in the past 2 weeks it feels like my brain is gonna pop anyway, question is fairly simple for someone who engages in local rankings and I appreciate the question may be a little guess work but isn't SEO mostly guessing anyway? From what I've read and learned that Google works of a system called nap for local rankings (With many other factors but this question is purely based on NAP). For people who care about local rankings NAP stands for Name of Business / Address of Business / Phone Number for Business. Now what what I've read you don't need the whole NAP to be on one website, a P or just a N can help towards your local rankings. It's believed that NAP rewards more than just P and N for example but knowing Google they might have a diversity checker which is my concern what your get to in a moment. Now of course sites weight differently where your business is posted, it's certainly going to be more credible if your NAP details are on your national phone book than say a blog site, so taking in this consideration too. Pure Guess (Not apart of the question but none the less makes a good read on my belief). Now my guess work would make me believe that the formula would look something like (N)+(A)+(P)x(T) So (N)name would be 1 or 0 to indicate present or not So (A)dress would be 1 or 0 to indicate present or not So (P)hone would be 1 or 0 to indicate present or not So (T)rust would be 1-100 to indicate level of trust So a phone number appearing on youtube might look something like 0+0+1x95= 95 and a NAP appearing on your national phone book might look something like 1+1+1x100= 300 Please note that I'm not saying this is the sole factor and I'm sure its way more complex that this with things like other factors on the page, off the page (Reviews, Links, Clicks) and so on but its still a contributor). The Question My question is fairly simple and I'd imagine hard to impossible to have an actual definite answer to this but maybe someone has seen official wording else where on this, is it bad to include address or phone number in the Meta Description? The reason I ask is that one of my competitors has these elements in the meta descriptions and their local rankings are absolutely superb, the problem I have with this is scrap bot sites like 'Similar Too' 'Seo Rankings' and 1,000's of the other scrap box networks that scrap site and then make urls with your site information are mostly limited to your meta description what this means that your phone number, address and sometimes even your company name if the domain is exact will appear as AP, and even NAP on thousands of websites. So, is it a bad strategy to include phone number and address in meta description, everything I read into would suggest its good of course with the downside of maybe lowering quality of description for click thoughts but top rankings would increase this 10 folds anyhow..

• Five Best Practices for Going Mobile

  - by kellsey.ruppel

  76% of IT decision makers indicate mobile trends will have a high to extremely high impact on their organization. Has your organization gone mobile? Looking for some ideas on how to get started? John Brunswick shares his Best Practices for Going Mobile. Mobile technology has gone from nice-to-have to a cornerstone of user engagement. Mobile access enables social networking, decision support, purchasing, content consumption, and location-based searching, extending experiences beyond what is available in traditional desktop computing.  Organizations rushing to ensure their brand's mobile availability may have taken a tactical approach to implementation, but strategically approaching mobile can enable greater returns on a similar investment and subsequent mobile projects. Here are some strategic considerations for delivering products, services, and information to mobile constituents.  Who, Why, and What? Ask yourself these key questions: who are you attempting to engage through the channel, and why are they engaging you through this channel? What experience will satisfy their needs? What outcome will support your core business? Will you be informing and/or transacting with this person?  Mobile Behavior. Mobile users generally engage for a very specific purpose. Ensure that access to information, services, and products is streamlined. Arriving on a mobile site through search only to be asked to search again frustrates users.  Mobile Is Broad. After establishing the audience and goal, review technology requirements to support them. Do you need a mobile Website, native mobile application, or both? Do you need to support multiple devices? Know the difference between native mobile and mobile Web.  Social Strategy. Users are more likely to trust reviews from peers than marketing information from a vendor. If you are selling products or services, be sure to make social integration part of your strategy.  Content Management. Consider a shared content platform strategy for Web and mobile projects. Fresh, consistent content is important for high-quality experiences. Read more from John Brunswick.We'll also be talking mobile strategies and how you can transform your portal experience and optimize online engagement -- making your portals more interactive and more engaging across multiple channels in a webcast tomorrow. We hope you'll join us!

• How to Overcome or fix MIXED_DML_OPERATION error in Salesforce APEX without future method ?

  - by sathya

  How to Overcome or fix MIXED_DML_OPERATION error in Salesforce APEX without future method ?MIXED_DML_OPERATION :-one of the worst issues we have ever faced :)While trying to perform DML operation on a setup object and non-setup object in a single action you will face this error.Following are the solutions I tried and the final one worked out :-1. perform the 1st objects DML on normal apex method. Then Call the 2nd objects DML through a future method.    Drawback :- You cant get a response from the future method as its context is different and because its executing asynchronously and that its static.2. Tried the following option but it didnt work :-    1. perform the dml operation on the normal apex method.    2. tried calling the 2nd dml from trigger thinking that it would be in a different context. But it didnt work.    3. Some suggestions were given in some blogs that we could try System.runas()   Unfortunately that works only for test class.   4. Finally achieved it with response synchronously through the following solution :-    a. Created 2 apex:commandbuttons :-        1. <apex:commandButton value="Save and Send Activation Email" action="{!CreateContact}"  rerender="junkpanel" oncomplete="callSimulateUserSave()">            Note :- Oncomplete will not work if you dont have a rerender attribute. So just try refreshing a junk panel.        2. <apex:commandButton value="SimulateUserSave" id="SimulateUserSave" action="{!SaveUser}"  style="display:none;margin-left:5px;"/>        Have a junk panel as well just for rerendering  :-        <apex:outputPanel id="junkpanel"></apex:outputPanel>    b. Created this javascript function which is called from first button's oncomplete and clicks the second button :-                function callSimulateUserSave()                {                    // Specify the id of the button that needs to be clicked. This id is based on the Apex Component Hierarchy.                    // You will not get this value if you dont have the id attribute in the button which needs to be clicked from javascript                    // If you have any doubt in getting this value. Just hover over the button using Chrome developer tools to get the id.                    // But it will show like theForm:SimulateUserSave but you need to replace the colon with a dot here.                    // Note :- I have given display:none in the style of the second button to make sure that, it is not visible for the user.                    var mybtn=document.getElementById('{!$Component.theForm.SimulateUserSave}');                                    mybtn.click();                }    c. Apex Methods CreateContact and SaveUser are the pagereference methods which contains the code to create contact and user respectively.       After inserting the user inside the second apex method you can just set some public Properties in the page,        for ex:- created userid to get the user details and display in the page to show the acknowledgement to the users that the User is created.

• Cloud service and IM protocol advice, for a backend to group chat mobile app

  - by Jonathan

  Overview I’m going to develop an app on Android and iOS. It will allow users to set up group ‘chat rooms’ and talk on chat rooms set up by other users. The service needs to be highly scalable, such that it could accommodate a massive increase in users overnight (we can only dream). Chat requirements The chat protocol used should be flexible: it should allow me to determine who can view/post on ‘chat rooms’ based on certain other factors, as determined by the first poster/creator of the particular ‘chat room’. It should also allow for users to simply install the app and begin using the service, after only providing a simple nickname (which could be changed later). Chat protocol plans Having looked around I think the XMPP protocol is the best candidate. In particular the Multi-user chat extension looks like what I’ll need. Would this be most suited to my requirements, or do you know another potential solution? Cloud service I have been deciding between Amazon Web Services, Google App Engine and Windows Azure. I’m coming to the conclusion that Azure will be best, as it is easier to manage than AWS (ease of scalability will be a key factor in the design), I think it may be less restricted than GAE, plus Azure will soon have toolkits to allow easy interfacing with both Android and iOS phones. Is this the decision you would have made, or would you recommend/look into other cloud services? General project philosophy I have only recently started looking into this project’s feasibility, and am no expert on any of its aspects. So wherever possible I will leave the actual implementations to experts, i.e. choosing a higher-level cloud service, using a well-documented plugin of a, proven reliable, group chat protocol etc. My background I have some programming knowledge from a computer science degree. Main languages I’ve used have been Java and Python, but I don’t want this to affect design decisions for the project. The most appropriate languages for the task should be used, i.e. I don’t mind learning a lot of new skills (my current programming levels are relatively basic anyway). Thank you Thanks for reading, and any advice you have about any aspect would be greatly appreciated :-)

• Managing Joomla via Android

  Surprisingly, it was only today that I actually looked for possible solutions to write more content for my blog. Since quite some time I'm using my Samsung Galaxy Tab 10.1 for all kind of social media activities like Google+, FB, etc. but also for my casual mail during the evening hours. And yes, I feel a little bit guilty about missing the chance to use my tablet to write some content here... OK, only a little bit. ;-) These are not the droids you are looking for But those lazy times are over! While searching the Play Store with the expression 'joomla' I got three interesting hits: - Joomla Admin Mobile! - Joooid - Joomla! Security Checklist After reading the reviews I installed the two later apps. Joomla! Security Checklist The author clearly outlines here that the app is primarily for his personal purpose to have safety checklist at hand at anytime. I guess that any reader of this article has an Android based smartphone or tablet, so that simple app should be part of your toolbox when using Joomla! for your websites. Joooid plugin & app Although I was looking for an app that could work with the default XML RPC interface of Joomla I have to admit that this combination of an enhanced Web service suits me better, mainly due to performance reason. The official website has not only the downloads for Joomla versions 1.5 - 2.5 but also very good and easy to follow step-by-step instructions to prepare your server for the Android app. It will take you less than 5 minutes to get it up and running. For safety reasons, I recommend that you should configure your Web server to have an additional authentication layer on the plugins folder. The smartphone app has the ability to run against HTTP authentication. Personally, I like the look and feel of the app. It is a little bit different compared to the web UI but still easy to use. In fact, this article is the first one written in the Joooid app. At the moment, I only miss the ability to have list tags. Quick and easy Writing full-fledged articles with images, a couple of hyperlinks and some styling here and there should be left to the desktop. At least for the moment. Let's see whether I'm going to change my mind on this during the upcoming months... I'll give it a try, and hope to publish at least once per month to write some content using Joooid. Actually, it would be great to have some feedback about other Joomla! clients in the wild.

• Virtualized data centre&ndash;Part four: The design

  - by marc dekeyser

  Welcome back to the fourth post in this series! Today we will have a look at what Microsoft recommends as a “private cloud design” and what I will make of it. Whilst my own solution is based of the reference architecture, it is quite different indeed! An important thing to know is that, whilst I am using the private cloud as a reference, I am skipping most of the steps in designing a private cloud. If that is why you are here, please read the links at the end of the article and skim through my own content. A private cloud is much more process driven than just building a virtual infrastructure… The architecture of it all… So imagine for a minute that you have unlimited funds to build this lab of yours… You’d want redundancy on all levels and separation of each network where possible! Unfortunately we don’t have that luxury and, as you saw me hinting at in the previous article, our own design will be more limited but still quite capable! Networking From the networking perspective I will not have a fully redundant network, after all, this is but a lab environment! Thanks to Server 2012 I will be able to use bonding on my NIC’s and use LACP to improve the performance on that part. Storage As I mentioned in the previous article a Synology DS1218+ will be used for iSCSI provisioning. This device has 2 NICs on-board which can be bonded in to one 2 Gbps interface giving me a decent throughput and making the disks the most limiting factor in the storage design. Domain controllers and extra infrastructure Server 2012 completely supports running domain controllers virtualized and has no need to actually have a reachable DC when booting… That being said I need a remote access machine to power on the hosts (I have no need for them running 24/7) and a possible System Center VMM 2012 box (although server 2012 is not supported until SP1 :( ). Undecided on if I am to install those boxes separately or as a virtual machine… Which amounts to… Something like this pretty picture!                   Sources Microsoft Private Cloud Solutions Repository (en-US) http://social.technet.microsoft.com/wiki/contents/articles/12131.microsoft-private-cloud-solutions-repository-en-us.aspx Reference  Architecture: http://social.technet.microsoft.com/wiki/contents/articles/3819.reference-architecture-for-private-cloud.aspx Private Cloud Reference Model: http://social.technet.microsoft.com/wiki/contents/articles/4399.private-cloud-reference-model.aspx
