  • Using "Google Guava" in coding interviews

    - by kbgn27
    I attended a in-person interview recently and performed well. But surprisingly I got rejected. When I asked the HR for reason, he contacted the technical interviewer and told me that I was syntactically wrong while coding. I used Google Guava for coding. So my code looked like this: List<String> items = Lists.newArrayList() instead of List<String> items =new ArrayList<String>(); I know that the code will compile and work as expected.Is it ok to use third party libraries like Google Guava in interviews?

  • Programming C++ using Qt4

    - by DaGhostman Dimitrov
    Hey guys I am really new to the C++ programing I have a little knowledge in C and a bit more in C++, but I do not know them enough to call myself a programmer. I am working as a PHP Web Developer I like being a crafts man and creating things so that is the reason to combine the programming with web development. I think that I could really benefit from both of them and so... My question is: Is it a good Idea to learn C++ with Qt or not? Can you give me pros and cons of both? Note: I do not want to become a programmer and give up the web development I want to combine them both.

  • How to play a fixed frequency sound using Python

    - by user98415
    I have tried a number of ways of playing a fixed frequency sound (e.g. 1000Hz) and nothing works. I have downloaded "beep" and that makes no noise. I tried interfacing to pyao, and that had no effect. I tried interfacing to audiere, and get a runtime error indicating the library could not be found, despite installing it from the software centre. Any guidance for installation of appropriate libraries and relevant code would be most appreciated. I cannot generate .mp3/ .wav files for this, but need to generate the tones at run time. Many thanks for you

  • How to prevent overlapping of gunshot sounds when using fast-firing weapons

    - by G3tinmybelly
    So I am now trying to find sounds for my guns but when I grab a gun sound effect and play it in my game a lot of the sounds are either terrible sounding or have this horrible echoing effect because as a gun shoots sometimes the previous sound is playing still. public void shoot(float x, float y, float direction){ if(empty){ PlayHUD.message = "No more bullets!"; return; } if(reloading){ return; } if(System.currentTimeMillis() - lastShot < fireRate){ //AssetsLoader.lmgSound.stop(); return; } float dx = (float) (-13 * Math.cos(direction) + 75 * Math.sin(direction)); float dy = (float) (-14 * -Math.sin(direction) + 75 * Math.cos(direction)); float dx1 = (float) (-13 * Math.cos(direction) + 75 * Math.sin(direction)); float dy1 = (float) (-14 * -Math.sin(direction) + 75 * Math.cos(direction)); PlayState.effects.add(new MuzzleFlashEffect(x + dx1, y + dy1, (float) Math.toDegrees(-direction))); PlayState.projectiles.add(new Bullet(this, x + dx, y + dy, (float) (direction + (Math.toRadians(MathUtils.random(-accuracy, accuracy)))))); if(OptionState.soundOn){ AssetsLoader.lmgSound.play(OptionState.volume); } bulletsInClip--; lastShot = System.currentTimeMillis(); } Here is the code for where the sound plays. Every time this method is called the sound is called but it happens so often in this case that there is this terrible echoing. Any idea on how to fix this?

    Problem Scenario: There is an enum keeping track of operations to be performed on a table Public Enum PartitionKey { Createtask, Updatetask, Deletetask } User is entering the value for the operation to be performed and the code to check the value entered in switch case. Switch (value) {           case PartitionKey.Createtask.ToString():          {          Create();          break;          }          case PartitionKey.Updatetask.ToString():          {           Update();           break;          }          case PartitionKey.Deletetask.ToString():          {           Delete();          break;          } } and it displays as error as “.” Solution: One of the possible implmentation is as below.

  • Is using dirname(__FILE__) a good practice?

    - by webose
    Looking at the code of Joomla I see that in the first line of the index, it defines the base path of installation with dirname(__FILE__). Is this a possible risk for the site?

If yes, is it convenient to use this function?

  • Analytics for Windows 8 apps using Markedup

    - by nmarun
    The Windows 8 store does provide some analytics information to you in terms of downloads by market or by age group, ratings, in-app purchases. I find that a little too limiting.

  • Using SQL Server's Output Clause

    When you are inserting, updating, or deleting records from a table, SQL Server keeps track of the records that are changed in two different pseudo tables: INSERTED, and DELETED. These tables are normally used in DML triggers. If you use the OUTPUT clause on an INSERT, UPDATE, DELETE or MERGE statement you can expose the records that go to these pseudo tables to your application and/or T-SQL code.
