• How should I get my code ready for OpenSourcing it and putting it on GitHub?

  - by Sempus

  In a few weeks, my project is going to be finished and I want to start getting my code ready for other people to use it. I am going to be posting everything to GitHub so people can tweak it and hopefully make it better. I guess what I'm asking is, what would be the best way to make sure my code is sufficiently documented and worded right for other people to use? I know you should always comment everything and I'm going to be putting in the @params feature for every method, but are there any other tips in general?

• What &lsquo;enterprise&rsquo; doesn&rsquo;t understand about risk

  - by Liam McLennan

  Enterprises (large bureaucracies) obsess about risk. I think it is because of the inertia generated by the process and politics that they have to deal with. The trouble is that they respond to risk in precisely the wrong way: by adding complexity. Need to call a method? Better wrap it in WCF service. Need to talk to another application? Better hook a message queue to a service bus connected to a biztalk sharepoint – on Oracle. Here is a simple guide: Complexity increases risk. Simplicity reduces risk.

• Name for this antipattern? Fields as local variables

  - by JSB????

  In some code I'm reviewing, I'm seeing stuff that's the moral equivalent of the following: public class Foo { private Bar bar; public MethodA() { bar = new Bar(); bar.A(); bar = null; } public MethodB() { bar = new Bar(); bar.B(); bar = null; } } The field bar here is logically a local variable, as its value is never intended to persist across method calls. However, since many of the methods in Foo need an object of type Bar, the original code author has just made a field of type Bar. This is obviously bad, right? Is there a name for this antipattern?

• How can I register a domain that requires country residency?

  - by zzatkin

  I tried to register a .pm domain from ovh.co.uk, but they e-mailed me saying they want valid proof that I am a resident of the United Kingdom. I currently live in the United States though. I am aware that I have to be a resident. That's not the question I'm asking. I want to know if it's possible, whether through some website that will get residency or some 'hacking' method, to register the domain I am interested in without having to physically be a resident of the country. I will try and find out if ovh.co.uk will charge me an extra fee, but until then I am curious to know if there is any way I could do this. Also, is there any other website I could purchase .pm domains from?

• Why does Linq to Entity Sum return null when the list is empty?

  - by Hannele

  There are quite a few questions on Stack Overflow about the Linq to Entity / Linq to SQL Sum extension method, about how it returns null when the result set is empty: 1, 2, 3, 4, 5, 6, 7, and many more, as well as a blog post discussing the issue here. Now, I could go a flag these as duplicates, but I feel it is still an inconsistency in the Linq implementation. I am assuming at this point that it is not a bug, but is more or less working as designed. I understand that there are workarounds (for example, casting the field to a nullable type, so you can coalesce with ??), and I also understand that for the underlying SQL, a NULL result is expected for an empty list. But because the result of the Sum extension for nullable types is also not nullable, why would the Linq to SQL / Linq to Entity Sum have been designed to behave this way?

• Is there such a concept as "pseudo implementation" in software development?

  - by MachuPichu

  I'm looking for a label to describe the practice of using human-based computation methods or other means of "faking" an algorithm for the sake of getting a product or demo off the ground quickly without spending the time to develop an technical/scalable/analytical solution? Eg: using Amazon Turk to count the number of empty tables in a restaurant. I'm also looking to learn more about this subject, but not sure what to search for. Human-based computation is only one method, I'm interested in the general idea of pseudo-implementation. Any ideas, recommended reading? Thanks

• How to work on my personal ideas during the weekend? [closed]

  - by nurne

  I'm working full time 5 days a week, mostly between 10 and 14 hours a day. In the end of the day I'm very tired and just wanna take a shower, hang out and go to sleep. I have a lot of ideas that I want to implement and someday sell maybe through an online software business. I have my weekends free. However, when I get to the weekend I can't even imagine myself turn on the computer. But I really want to make my ideas happen, and I can't leave my job right now to devote myself only to my ideas. What do you say? Do you find some method helpful? Do you use some technique? Thanks

• How should dependencies be managed across a modular application?

  - by bear

  Let's say that we have a structure like this: Application -- Modules --Module1 -- Controller -- PublicHelper --Module2 -- Controller -- PublicHelper Whereby a module's Public Helper can provide helper functions. In nearly every module helper, the helper needs to access another module's public helper methods. Let's say for instance, in a PHP application: Module1 provides functionality to create a sale, and as part of the class Module1PublicHelper extends AbstractModuleHelper { public function createSale($customerId, $param, $param) { $userPublicHelper = // grab an instance of the user public helper $currentUser = $userPublicHelper->getCurrentUser(); } } class Module2PublicHelper extends AbstractModuleHelper { public function getCurrentUser() { //do something return $user; } } In this situation, the method needs to obtain an instance, either new or whatever of the user public helper. Given that all of Module Public Helper classes are instantiated with a minimum set of constructor params, e.g. EntityManager, what would be the best way to get a copy of it? Obviously, we can't really inject the user public helper class into the class containing createSale One solution would be to use a service locator or registry, however, testing the application isn't exactly easy.

• Application window as polygon texture?

  - by nekome

  Is there a way, or method, to have some application rendered as texture in 3D scene on some polygon, and also have full interactivity with it? I'm talking about Windows platform, and maybe OpenGL but I guess it doesn't matter is it OGL or DX. For example: I run Calculator using WINAPI functions (preferably hidden, not showing on desktop) and I want to render it inside 3D scene on some polygon but still be able to type or click buttons and have it respond. My idea to realize this is to have WINAPI take screenshot (or render it to memory if possible) of that Calculator and pass it to OpenGL as texture for each frame (I'm experimenting with SDL through pygame) and for mouse interactivity to use coordination translation and calculate where on application window it would act, and then use WINAPI functions such as SetCursorPos to set cursor ant others to simulate click or something else. I haven't found any tutorials with topic similar to this one. Am I on a right track? Is there better way to do this if possible at all?

• Cocos2d push scene with parameter, the parameter is reset after push. How to troubleshoot? Thoughts?

  - by user72693

  In the helloWorldLayer.m, I push a scene with some parameter like this [[CCDirector sharedDirector] replaceScene:[CCTransitionFade transitionWithDuration:0.2 scene:[RootLayer sceneWithInt:123]]]; where the RootLayer I have a modified method +(CCScene *) sceneWithInt:(int) i{ CCScene *scene = [CCScene node]; GameplayLayer *layer = [[GameplayLayer node] retain]; [layer setTestInt:i]; [scene addChild: layer z:0 tag:100]; return scene; } In the above, the "GameplayLayer" has an Int property "TestInt" which I would like to set it before this layer is push. However, the moment the GameplayLayer is loaded, that TestInt property is reset to 0. It is not passing correctly. I remember in my last project this can be done. How to troubleshoot this?

• Simulating a sine wave/oscillating pattern for enemies

  - by Sun

  I'm creating a simple top down shooter, right now I have an enemy which simply follows the player. I'd like to change things up and have the enemies move towards the player but in a wave like motion. I have looked at some similar questions like this but they don't take into account for the Y changing. How can I simulate a wave like pattern for my enemies whilst they are homing into their target. Edit: Sample code In my update method I have the following: Vector2 trackingPos = position - target; trackingPos.Normalize(); position -= trackingPos * elaspedTime * speed;

• Using UNION in a query with PHP [migrated]

  - by work

  I have an SQL query which links 3 tables using UNION: $sql ="(SELECT Drive.DriveID,Ram.Memory from Drive,Ram where Drive.DriveID = Ram.RamID) UNION (SELECT Drive.DriveID,External.Memory from Drive, External where Drive.DriveID = External.ExtID)"; Suppose I want to get Ram.Name as well. How do I do this? If I use Ram.Name in the first SELECT statement it would not produce the correct result. Any method for tackling this? I want to do it using UNION.

• Multiplayer in a game. How to design it object wise?

  - by Ninetou

  I was suggested on StackOverflow to ask this question here. I'm working on a simple game and I was thinking of adding multiplayer feature but I'm a bit stuck. I'm not sure what approach should I take, keeping in mind good programming practices. I have a Player object which is created for each player but then I have many other classes that would have to be able to access them. The thing is, if I initialise them in, let's say my main method, then I can't relate to different instances of player class from other classes. The only solution to my problem that comes to my mind is using some form of global objects but afaik using anything globally in apps is usually not a good practice. Any suggestions/ideas?

• Variable-step update() in game loop is falling behind, how can I get around this?

  - by ThatsGobbles

  I'm working on a minimal game engine for my next game. I'm using the delta update method like shown: void update(double delta) { // Update code that uses `delta` goes here } I have a deep hierarchy of updatable objects, with a root updatable that contains several updatables, each of which contains more updatables, etc. Normally I'd just iterate through each of the root's children and update each one, which would then do the same for its children, and so on. However, passing a fixed value of delta to the root means that by the time the leaf updatables are reached, it's been longer since delta seconds that have elapsed. This is causing noticable desyncing in my game, and time synchronization is very important in my case (I'm working on a rhythm game). Any ideas on how I should tackle this? I've considered using StopWatches and a global readable timer, but any advice would be helpful. I'm also open to moving to fixed timesteps as opposed to variable.

• Output the total number of String Characters [migrated]

  - by Programmerwannabe

  My Question is what method should I use if I wanted to get the total number of characters a user inputs? without using arrays, i tried using .length() but it did not return all characters say from the first and lastname, it only returned the first name. Here's an example of my code. (Please dont laugh im really new in programming :) ) System.out.print("Enter your first and last name: "); String yourName = keyboard.next(); System.out.println("Your name has a total of " + yourName.length() + " numbers"); what happened was if i enter say "Neo Matrix" it would only return 3. I appreciate any help. thank you!

• I need to get past my permissions to recover data

  - by adsmz

  Due to some mishaps, I am unable to boot into Kubuntu at all. However, my data is still on the hard drive. I managed to get one of the other two computers to which I have access to read the disk by booting into a liveCD session of kubuntu. The only storage medium to which I have access is a 30 GB data stick. Here's where the trouble starts: In music alone, I have to back up about 60 GB. Obviously this is going to have to be split into chunks and moved over to the second spare PC until I can reinstall Kubuntu on my laptop. All of the data that needs backed up is behind a permissions wall, so while I can view it, I can't interact with it directly. I know copying and moving through the terminal can get around this with sudo cp or sudo mv, but is there a way to first compress multiple folders in a single archive, then move it? (While we're on the subject, what compression method would be best for large volumes of music in MP3, WAV, and OGG format?)

• aspect parameter validation [closed]

  Hi, Im doing a POC using Aspectj. class BaseInfo{..} class UserInfo extends BaseInfo{..} class UserService { public void getUser(UserInfo userInfo){..} public void deleteUser(String userId){..} } I've defined an advice, that gets invoked when I pass an UserInfo instance.But when i try to pass the BaseInfo, the advice is not getting invoked. Below block executes the afterMethod as expected for getUser. &ltaop:pointcut id="aopafterMethod" expression="execution(* UserService.*(..,UserInfo,..))" / &gtaop:after pointcut-ref="aopafterMethod" method="afterMethod" / But when i try to give BaseInfo instead of UserInfo, the aspect is not getting triggered. Am i missing something? Kindly help me on this issue.

• SQL Server Requery() sometimes hangs

  - by PSU

  I have an issue with Visual C++ and Microsoft SQL Server 2008R2. The following code will occasionally hang: Object->Update(); if(Object->CanRestart()) { //Why does this not return?? m_pDBRoRBaseObject->Requery(); } Object is derived from CRecordset. It looks to me as though a call to ::SQLExecute(m_hstmt) in the Requery() method is hanging, but I can't (with my current skill set anyway) figure out a way around this. Has anyone had a similar problem, or an insight of any sort?
