  • How to handle monetary values in PHP and MySql?

    - by Songo
    I've inherited a huge pile of legacy code written in PHP on top of a MySQL database. The thing I noticed is that the application uses doubles for storage and manipulation of data. Now I came across of numerous posts mentioning how double are not suited for monetary operations because of the rounding errors. However, I have yet to come across a complete solution to how monetary values should be handled in PHP code and stored in a MySQL database. Is there a best practice when it comes to handling money specifically in PHP? Things I'm looking for are: How should the data be stored in the database? column type? size? How should the data be handling in normal addition, subtraction. multiplication or division? When should I round the values? How much rounding is acceptable if any? Is there a difference between handling large monetary values and low ones? Note: A VERY simplified sample code of how I might encounter money values in everyday life: $a= $_POST['price_in_dollars']; //-->(ex: 25.06) will be read as a string should it be cast to double? $b= $_POST['discount_rate'];//-->(ex: 0.35) value will always be less than 1 $valueToBeStored= $a * $b; //--> any hint here is welcomed $valueFromDatabase= $row['price']; //--> price column in database could be double, decimal,...etc. $priceToPrint=$valueFromDatabase * 0.25; //again cast needed or not? I hope you use this sample code as a means to bring out more use cases and not to take it literally of course. Bonus Question If I'm to use an ORM such as Doctrine or PROPEL, how different will it be to use money in my code.

  • Including Microsoft.XNA.Framework.Input.Touch in a project?

    - by steven_desu
    So after running through tutorials by both Microsoft and www.xnadevelopment.com I feel very confident in my ability to get to work on my first game using the XNA Framework. I've manipulated sprites, added audio, changed game states, and even went a step further to apply the knowledge I had and figure out how to make animations and basic 2-dimensional physics (including impulses, force, acceleration, and speed calculations) But then shortly into the project I hit a curious bump that I've been unable to figure out. In wanting to implement menus, pause screens, and several different aspects of play (a "pre-level" prep screen, the level itself, and a screen after the level to review how well you did) I took a look at Microsoft's Game State Management sample. I understood the concept, although it was admittedly quite a lot to take in. Not wanting to recreate the entire concept by scratch (after all- what purpose would that serve?) I tried copying and pasting the sample code into my own ScreenManager class (as well as InputState and GameScreen classes) to try and borrow their ingenuity. When I did this, however, my project stopped compiling. I was getting the following error: The type or namespace name 'Touch' does not exist in the namespace 'Microsoft.Xna.Framework.Input' (are you missing an assembly reference?) Having read through their sample code already, I realized that this namespace and every function and class within it could be safely ripped from the code without losing functionality. It's a namespace simply for integrating with touchscreen devices (presumably Windows Phone 7, but maybe also tablets). But then I began to wonder- how come Microsoft's sample compiled but mine didn't? I copied their code exactly so there must be a setting somewhere that I need to change in Visual Studio in order to correct this. I tried creating a new project as a Windows Phone 7 game rather than a Windows game, however that only forced it to compile to a Windows Phone emulator and denied me the ability to change the resolution and other features which I clearly had the power to do in the sample code. So my question is simple - how do I properly use the namespace Microsoft.XNA.Framework.Input.Touch?

  • Empirical evidence regarding testability

    - by Xodarap
    A google scholar search turns up numerous papers on testability, including models for computing testability, recommendations for how ones code can be more testable, etc. They all come with the assertion that more testable code is more stable, but I can't find any studies which actually demonstrate this. Can someone link me to a study evaluating the effect of testable code vs. quality? The closest I can find is Improving the Testability of Object Oriented Systems, which discusses the relationship between design flaws and testability.

  • Should I listen to my employer and use CASE tools?

    - by omsharp
    My employer (Not a Developer) thinks that CASE tools will help us improve our development process and documentation. I am not sure about that, we are a small team of 5 developers building mobile banking solutions for local clients. I think CASE tools will be a waste of time and money as they need to be purchased and we will need some time before we get used to them and be efficient working with them for modeling and stuff. Code generation is another issue, I really think that the CASE generated code won't be as good as code written by good developers. I think that if we stick with agile princeliness, design patterns, use TDD, and keep our code clean. we should be good. And as far as Analysis and Design, I think simple UML diagrams on whiteboard should do the trick. Documentation is good and important, but should be made as little as possible and we should not focus on Docs and forget the code. This is what i think. Am I correct? or should I listen to my employer and start researching for an appropriate CASE Tool?

  • Does NaCl mean the death of Internet Explorer? [closed]

    - by Monika Michael
    From the wikipedia - Google Native Client (NaCl) is a sandboxing technology for running a subset of Intel x86 or ARM native code using software-based fault isolation. It is proposed for safely running native code from a web browser, allowing web-based applications to run at near-native speeds. (Emphasis mine) (Source) Compiled C++ code running in a browser? Are other companies working on a similar offering? What would it mean for the browser landscape?

  • Why blogger puts BR tags only when content served via RSS feed?

    - by tamashumi
    I have a problem with using my new blog RSS feed. I wrote a post (the first one) with some code examples formatted by SyntaxHighlighter. To paste a code sample I'm switching from WYSIWYG to HTML view and put the code inside pre tag like this (don't worry, h4 tag was opened a line above the screenshot area): The problem is that such pre tag, when later accessed via RSS feed contains br tags instead of new line characters. Below is screenshot of the adequate RSS source code: What's most important when accessed via www, the post html is formatted fine, no brs inside pre. I verified that by downloading the blog post with wget. So I believe this isn't SyntaxHighlighter issue nor any 'new line' formatting on blog post save. This is a real problem as I want aggregate my blog on employers blog and all formatting of code examples is broken because of that. The base question is: how to get rid of those unwanted brs served via RSS? What's strangest friend of mine also uses blogger for such aggregation and he has no such issue. I checked his RSS feed and there are no brs inside pre tags. We also compared settings of our blogs. However we have found no clue. The blog post RSS for the blog (just check source and search for string: pre class="brush) Mentioned friend's blog Last thing: I see content served from RSS is now also html encoded. If I remember well, it wasn't previously.

  • Sprite Body can not stop

    - by Diken
    Hey i have issue regarding jump sprite body. In my code i am using moveLeft and moveRight Button and when i am press moveRight Button using following code if (moveRight.active==YES) { b2Vec2 force=b2Vec2(4,0); ballBody->SetLinearVelocity(force); } Its move perfectly and When i release this Button than sprite body stop using following code else { b2Vec2 force=b2Vec2(0,0); ballBody->SetLinearVelocity(force); } But when i put this else part then jump can not done. My jump code is following if (jumpSprite.active==YES) { NSLog(@"Jump Sprite"); b2Vec2 locationWorld; locationWorld=b2Vec2(0.0f,4.0f); double force=ballBody->GetMass(); ballBody->ApplyLinearImpulse(force*locationWorld, ballBody->GetWorldCenter()); } If i remove else part then jump will perform complete but sprite body can not stop after release button. So what to do?? Thanks in advance

  • C++ Succinctly now available!

    - by Michael B. McLaughlin
    Over the summer I worked with SyncFusion to create an eBook based off of my C# to C++ guide for their free Succinctly Series of eBooks. Today the result, C++ Succinctly, was published for download. It is a free (registration required; they make tools and libraries for .NET development so you might get an occasional email from them – I’ve been signed up for a few months and have had maybe 3 emails total so it’s not horrible super spam or anything ) and you can download it as a PDF or a Kindle .MOBI file (or both). I’m excited with how it turned out and enjoyed working with the people at SyncFusion. The book contains a total of 20 code samples, which you can download from BitBucket (there’s a link very early in the book). Almost all of the code is also inline in the book itself so that you don’t need to worry about flipping back and forth between your dev machine and your eReader (but if you want to try to understand a concept better, you can easily download the code, open it up in VS 2012, and play around with it to see what happens when you tinker with things). The code does require Visual Studio 2012 because of its expanded support for C++11 features and since I wrote all of the samples as Console programs for clarity and compactness, you will need a version that supports C++ desktop development (currently VS 2012 Pro, Premium, or Ultimate). Sometime this Fall, Microsoft will be releasing Visual Studio 2012 Express for Windows Desktop which should provide a free way to use the samples. That said, I tested all of the samples with MinGW and only the StorageDurationSample will not compile with it due to the thread-local storage code. If you comment that out then you can compile and run all the samples with MinGW (or using a recent version of GCC in a GNU/Linux environment, or any other C++ compiler that provides the same level of C++11 support that Visual Studio 2012 does). I hope it proves helpful to those of you who choose to check it out!

  • test coverage reality

    - by iPhoneDeveloper
    I am NOT doing test driven development and I write my test classes after the actual code is written. In my current project I have a test coverage of(Line coverage) %70 for 3000 lines of Java code.(Using JUnit, Mockito and Sonar for testing) But while I feel actually I am not covering and catching %70 of the problems that can occur. So my question is in theory is that possible to have a %100 Line coverage but in reality it is meaningless because of low quality of the test code and maybe a %40 well written test code is much better than a bad %100 coverage? or we can always say line coverage more or less gives the percentage of all covered issues?

  • What do I need to learn to decide on rename/recompile source package names because of company rebranding?

    - by Roberto Linares
    My company is currently at a rebranding process and the brand names have been used in the sources' package names but these names are only visible to developers who maintain this code so nobody from project management is really interested in changing them considering also that it would imply the recompiling of several old components. What factors do I need to consider when deciding on a change like that? I don't know if I should worry about legal issues or not and if so, how to address this with project management. More background details. I have all the sources and dependencies but since the company rebranding, other development areas have adopted some of the code that needs package name-changing so I cannot take the decision only by myself so I don't make everyone else's code to crash with my core components and I cannot change other areas' code without the permission of those areas' users so yes, my concern is more political than technical. I am going try to coordinate the involved it areas to make the change anyway, since it seems to be the best approach.   Unfortunatelly in my company there's no continuous integration build server so we build our code manually on demand and to get something to production I have to justify the change (even just the package name changing) to QA with an user requirement and some other bureaucratic documentation so that's why I was hesitating the change in first place.

  • One-way platform collision

    - by TheBroodian
    I hate asking questions that are specific to my own code like this, but I've run into a pesky roadblock and could use some help getting around it. I'm coding floating platforms into my game that will allow a player to jump onto them from underneath, but then will not allow players to fall through them once they are on top, which require some custom collision detection code. The code I have written so far isn't working, the character passes through it on the way up, and on the way down, stops for a moment on the platform, and then falls right through it. Here is the code to handle collisions with floating platforms: protected void HandleFloatingPlatforms(Vector2 moveAmount) { //if character is traveling downward. if (moveAmount.Y > 0) { Rectangle afterMoveRect = collisionRectangle; afterMoveRect.Offset((int)moveAmount.X, (int)moveAmount.Y); foreach (World_Objects.GameObject platform in gameplayScreen.Entities) { if (platform is World_Objects.Inanimate_Objects.FloatingPlatform) { //wideProximityArea is just a rectangle surrounding the collision //box of an entity to check for nearby entities. if (wideProximityArea.Intersects(platform.CollisionRectangle) || wideProximityArea.Contains(platform.CollisionRectangle)) { if (afterMoveRect.Intersects(platform.CollisionRectangle)) { //This, in my mind would denote that after the character is moved, its feet have fallen below the top of the platform, but before he had moved its feet were above it... if (collisionRectangle.Bottom <= platform.CollisionRectangle.Top) { if (afterMoveRect.Bottom > platform.CollisionRectangle.Top) { //And then after detecting that he has fallen through the platform, reposition him on top of it... worldLocation.Y = platform.CollisionRectangle.Y - frameHeight; hasCollidedVertically = true; } } } } } } } } In case you are curious, the parameter moveAmount is found through this code: elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; float totalX = 0; float totalY = 0; foreach (Vector2 vector in velocities) { totalX += vector.X; totalY += vector.Y; } velocities.Clear(); velocity.X = totalX; velocity.Y = totalY; velocity.Y = Math.Min(velocity.Y, 1000); Vector2 moveAmount = velocity * elapsed;

  • Algorithm to increase odds of matching when randomly selecting

    - by Bryan
    I am building a mobile game loosely based on dual n-back http://brainworkshop.sourceforge.net/tutorial.html Now with the game I have 9 squares (numbered 1 through 9) and 9 letters (A through K) In the current code, I randomly select a square (e.g. 3) and a letter (e.g. C), then repeat the random selection for the next turn. For 1-back, I test whether either, neither or both match the previous turn. The problem with my current code is I get very few matches - I can go through many turns without having either match. How can I increase the match frequency, or alternatively decrease the randomness so a match is more likely? I am not looking for specific code (but pseudo-code would be fine) - just more an approach to increase match frequency.

  • Collaborative work (small team) - Best practices

    - by LEM01
    I'm currently working in a very small team of programmers (2-3) and I'm looking for advices/best practices on how to organise our work. We're all working on the same application using PHP. Today we're kind of all working on our way. Today situation: List item that have to be worked on by each dev 1/week. What has to be done is defined at a high functional level (ex: Build the search engine for this product..) Commit / merge our individual branches (git) every week before the next meeting No real dev rules, no code review No test written (aouutch) Problems faced: Code quality issue: discovering someone else code is sometime tough (inline, variable+function+class names, spaces, comments..) Changes in already existing classes (impact on someone else work) Responsibility of each dev unclear: after getting someone else code and discover something messy, should I make the change? Should he make the change? How to plan those things,... What I'm looking for: Basically I'm looking into structuring the way we develop things in order to avoid frustration and improve overall quality. How to define coding standards (naming convention, code rules...)? Do you you any validation script to make sure code is valid before committing? Do you think that defining an architect role in the team is needed? Someone that would actually define what has to be developed during the next phase. By defining interfaces or class descriptions that have to be written. (Does it make sense in such a small team?) Today we're losing time into understanding what others did or tried to do, we're also losing time in discussion like "you should have done it that way! Why is this class doing that and not that..? Shouldn't we have a embedded class rather that this set of data...". I'm looking into a work process, maybe with more defined responsibilities and process in order to improve our performance. If you have experience, advices, best practices or anything to share that we could benefit from it will be much appreciated! Thanks a lot for your time!

  • If I send an IPA over TestFlight, can it be used to deploy to the app store?

    - by Reid Belton
    I am currently working for a small startup. I was previously under contract, now I am working for equity (no pay). The thing is, there is not yet a signed agreement in place as the details are being worked out. I may finish development before the contract is ready. I'm not currently under any contract or agreement, so the other party doesn't have any legal claim (that I know of) to the code I'm writing now, other than NDA (which just precludes me from cutting him out and releasing on my own). He already has the old code that I wrote under contract. I've made it clear to the other party that I won't submit the app or turn over the code until there's something signed to protect my interests. I've stopped pushing commits to the company repo (I'm now the only developer actively working on the project). However, I would still like to send builds over TestFlight for feedback and testing purposes. The other party has access to the developer portal and iTunes Connect for code signing, etc. Things are amicable and I don't foresee getting burnt on this, but I'm not going to put myself in that position. My concern is that if I send a finished build via TestFlight, it could be extracted and submitted to the app store without my participation. They wouldn't have the source for future maintenance and updates, of course, but it could be reverse-engineered by another developer later working from the old code base. Is this technically feasible at all? If so, is there a way I can send builds for testing while protecting my interests?
