• Wait for Unity 4.3? [on hold]

  - by RoarG

  We are currently in a pre-production of developing a 2d game in Unity but with the arrival of Unity 4.3 around the corner we were contemplating waiting for the release 4.3 instead of starting on 4.2, mainly since 4.3 got native 2d support. Is this something to be worried about, or do we need to start over to take use of the advantages that 4.3 brings, or does it matter at all? What benefits does one get in Unity 4.3, considering developing a 2d game? and is it a lot of tweaking to rework if we start the project before 4.3 release?

• oDesk agency for subcontracting

  - by lorddev

  My question has to do with whether to create an oDesk agency (I've searched to verify that oDesk questions are appropriate). I have a project for which I was hired, and the client has given me authorization to subcontract a few hours of UI/UX expertise. I don't want to make the client hire the UI/UX guy directly; however, if I hire someone with my company account and then bill the client for the time, oDesk is taking 19% off the top (10% twice). I've checked their FAQ and filed a support ticket several days ago, but nobody has replied. If there's anyone who has had experience with oDesk agencies, do you think it can be handled this way? In other words, can I be the developer in my own agency while also having a UX person on the team?

• How to get some experience in a new programming language? [closed]

  - by BeCool

  I have commercial experience in one programming language but I want to make a switch to another programming language (C#/.NET). I am in full-time employment so whenever I get free time I read relevant books or use online resources available. My questions are - How do I develop experience in the new language of interest (without leaving current job)? The best way I find to learn is to develop a project - How do you / Where can you find new test projects which you can refer to in the interview (these don't have to be real projects but perhaps I can take the code with me in a usb stick as proof). Do you have any tips/advice for me regarding best way to switch career? My lanugauge of choice is C# - so c# related answers will be appreciated.

• lower graphics setting in ubuntu

  - by zkent

  First off, I am new to Ubuntu. I come from a Windows background (DOS before that) and am loving it so far. I installed it on an older Dell laptop that I wanted to get another year out of. I set this machine up primarily as a LAMP development machine for a project I am working on. The machine is a Vostro 1500 and it has 4GB RAM (maxed) and an upgraded hard drive. I can't watch YouTube videos for long before it starts to overheat and start acting sporadic. I can live without YouTube but every so often the application switching (alt-tab) gets slower and begins not showing all applications and the Dash home quits displaying properly. I am sure I am asking a lot of this old machine. What I really want to know is: are there any settings in Ubuntu that allow me to lower the graphic effects (fade-ins, transparencies, fancy transitions, etc) that would be less taxing on the video card?

• What is the best way to INSERT a large dataset into a MySQL database (or any database in general)

  - by Joe

  As part of a PHP project, I have to insert a row into a MySQL database. I'm obviously used to doing this, but this required inserting into 90 columns in one query. The resulting query looks horrible and monolithic (especially inserting my PHP variables as the values): INSERT INTO mytable (column1, colum2, ..., column90) VALUES ('value1', 'value2', ..., 'value90') and I'm concerned that I'm not going about this in the right way. It also took me a long (boring) time just to type everything in and testing writing the test code will be equally tedious I fear. How do professionals go about quickly writing and testing these queries? Is there a way I can speed up the process?

• 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?

• Android - Unity3D: setVisibility(View.VISIBLE) crashes

  - by Kazoeja

  I have a unity project and I use a Android (java) plugin to get camera data. I draw this on a TextureView. I want to hide/show this view when I press a button in unity. But my app crashes when I setVisibility onCreate UnityPlayer.currentActivity.addContentView(texView, new FrameLayout.LayoutParams(400, 400)); java: public void HideVideo() { //Hide view _TextureView.setVisibility(View.INVISIBLE); } Is there an extra function I need to call, or may I only call it on certain times? None of these thins work, they all make my app crash. _TextureView.setVisibility(View.INVISIBLE); _TextureView.setActivated(false); _TextureView.setAlpha(0); _TextureView.setTranslationY(-1000);

• How to elegantly work with a lot of print functions?

  - by user1824372

  I'm working on a Python project that is executed on a terminal (or console) for which I am planning to implement a GUI. I did not major in CS so I really have no idea how to effectively design a terminal GUI such that: the user interface looks good in GUI, it is directed to a certain widget, let's say, a text label, or a bottom bar, or a hide-able frame. Do you have any suggestions? Currently, I am using the print function to provide essential information on STDOUT during execution, so a lot of print calls are distributed here and there in the code. I'm thinking of using macro-like variables such as 'FILE_NOT_EXISTS_MESSAGE' for printing, and all of them and their values would be defined in one file. Is that a standard way to do this? Should I introduce a logging system? In summary, I'm looking for a pattern for handling console output that is effective and adaptable.

• What could a kernel mode driver be possibly useful to?

  - by John Pell

  This might sound weird but there's an explanation for my question: I want to write something to impress a potential recruiter, and I want (to strenghten my skills) to create a program which should communicate with kernel mode driver(s). I'm not starting from a goal and trying to design the system to achieve it, I'm doing the opposite: designing the system and trying to justify it with a meaningful goal. So here comes the question: what could a kernel mode driver be possibly useful to? The answers that come to my mind right now are: I might want to communicate with hardware (not really my case, it's a software project mainly) I might want to mess around with the OS (security/hooking?) ?? I need some other examples like those

• Should we use python 2.6 or 2.7 or 3.x?

  - by lamwaiman1988

  The version of python which I am using is 2.6, and there is a 2.7 and 3.x. Usually I use python for some trivial program/snippet. I realize there are some major difference between 2.x and 3.x. I would really like to know, if I am going to make a bigger project with python, which version of python should I use? Should I upgrade to 2.7, or go to 3.x or stay with 2.6? The decision should be based on these terms: Number of user in the internet as a community. More users mean more open-source package and help from them. Functionality. Support from official development team. Compatibility for existing module/package. Thanks!

• How to access variables of uninitialized class?

  - by oringe

  So I've gone with a somewhat singleton approach to my game class: #include "myGame.h" int main () { myGame game; return game.Execute(); } But now I need to define a class that accesses variables in the instance of myGame. class MotionState { public: virtual void setWorldTransform (...) { VariableFromMyGameClass++; //<-- !? ...} }; I'm trying to integrate this class into my project from an example that just uses globals. How can I access variables of myGame class in the definition of new classes? Should I give up on my singleton approach?

• Implementing cache system in Java Web Application

  - by TGM

  I worked with JPA (Eclipselink implementation) and Hibernate. As I understand these two have great caching systems. I am interested in caching in a Web application and in order to better understand the process I'm trying to implement something on my own. Sadly, I cannot find any in depth documentation about this subject. I'm interested in things like high scalability, sharing memory on different machines and other important theoretical matters. Is there any tutorial or open project I could check out? Thank you! *LE: * I want to cache DB information in POJOs just like JPA or Eclipselink

• XNA + Windows Forms: How make them work together without making the trick of the custom GraphicsDeviceControl?

  - by Renann

  What I've found is a solution where you have to code a custom GraphicsDeviceControl to put inside the form (the well known tutorial from the APPHub), but that's not what I'm searching for. I would like to say that before start to right my question here, I "googled" a lot and I saw some questions here, but I couldn't find what I'm looking for. I would like to have the Draw/Update loops completly managed by XNAFrameWork (with XNA project and so), and not by a custom component. I hope you understand what I asked. Thanks in advance. Edit What's the most important thing for me and wasn't shown in the tutorial of APPHub is: where I have to put the input handling? That's one the problems that wasn't covered by the tutorial.

  - by Skeith

  I have tried to start programing with coco2dx but i have no idea where to start and the tutorials are no very not very helpful. What i am looking for is some tutorials/guides on how to begin using cocos2dx for the total beginner. Things like how to setup a project and run it and how to do simple things like draw graphics on the screen, play sounds and get input. I am running on windows 7 and have been told by the cocos2dx wiki that this may cause problems so if anyone has a solution to this that would also be helpful.

• Is a blob more efficient than a varchar for data that can be ANY size?

  - by BillyNair

  When setting up a database I want to use the most efficient data type for potentially fairly long data. Currently my project is to store song titles and thoughts pertaining to that song. Some titles might be 5 characters or longer than 100 characters and the thoughts could run pretty long. Is it more efficient to use a varchar set to 8000 or to use a blob? Is using a blob the same as a varchar, in that there is a set size it is allocated regardless of what it holds? or is it just a pointer and it doesn't really use much space on the table? Is there a certain set size of a blob in KB or is it expandable?

• Automatically delete files after they expire

  - by Auxiliary

  I've got this idea for some time and I was wondering if anyone has seen such a feature/app in any operating system and if you haven't, what do you think about it. Where do you think I should begin? The idea is simple. I think we all have those files that are made and probably used for a few days and then are left on our disk and we never delete them or even check to see if we need them again. It'd be cool if you could right click on a file and click on "Expire in.. 3 days" for example. And the file gets deleted after 3 days. I have a great need for this and maybe some people will find it useful. I was thinking of writing a script and use the Nautilus Action project in GNOME for a start.

• How to give life to my idea which belong to my company?

  - by pmod

  I wonder, what options do I have in the following situation. In the course of the several projects I realised the need in some auxilary software product (related to testing of the main products). I applied a creative approach to the matter and implemented a system which I think has a potential and looking promising (maybe not on the market but at least among some interested supporters). I have even more ideas related to this system and continue developing at my free and work time. It has become a work and hobby at the same time. Unfortunately, this work basically has nothing in common with the company's business and there is no way this will be organized in a form of standard development process and be presented to costumers as a product. What can you suggest in this situation? How to avoid breaching of contract? Have you had something similar in your career? What if my intention is to develop it as an open source project?

• Any idea of what to do with an old PC?

  - by phineas

  I got an old PC for free, similar to that one. Additionlly, I'm a hobbyist programmer who does mainly python and java under a linux (mostly ubuntu) development environment. And now I wonder what I could do with such a piece of crappy hardware and would be pleased to get a good answer. It's one thing if you code your app that could run on almost any pc (or webbrowser) but another if you got an own hardware platform which you could extend or more generally customize the way you like. What I would like to hear from you: Are you in a similar situation? Have you already done a project like that? What would be your ideas?

• writing 3d game [closed]

  - by user1432980

  I want to write a game as my final year diploma project.(I'm a 4th-year-student now so I've got a year and several months). But I don't know what to choose: either write my own game engine using DirectX9(10)(I don't like OpenGL) or use OGRE + PhysX(Don't like Unity) I'm more interested in writing my own game engine(but I wonder if I'll create engine on the same level as even Unreal 1.0 hah) but on the other side with PhysX I'll have advanced physics in my game and with OGRE I'll have good grahics. For 3d models I want to use Maya. What do you advise me to choose? As for me I've got a little DirectX experience,not bad C++ programming skills(but not expert's) and a little knowledge of Maya. My English isn't perfect either hah...

• Is CodeIgniter PHP Framework suitable for large ERP or Business Application?

  - by adietan63

  Is CodeIgniter is recommended for a large web based ERP or Business Application? I want to use CodeIgniter for my future Project and I'm so confused whether to use it or not. Im so worried about in the long term process or lifetime of the application that it may crashed or produce a bug or error. I also worried about the performance of the framework when the data becomes larger and containing millions of records. I searched on the internet the answer but there is no exactly answer that will satisfy me. I think this question is important for the programmers like me who wanted to use PHP Framework for their large business application. I need an advice from you guys in order to decide whether to use it or not. thank you very much!

• Repainting a window with a new scene with winapi (beginner question)

  - by user90760

  I'm following theForger's win32 API tutorial in order to create a GUI for a project. I've successfully made simple, one window applications, but I can't figure out how to repaint an entire window with new information. As an example: I have five buttons corresponding to five colors on the main application window. When a user clicks a color button, the entire window is repainted such that: 1. all five buttons are removed and a new "back" button is replaced, 2. the background is colored the color that was picked. I'm able to change the background color by trapping the button pressed message in my wndproc, but I can't figure out how to change the entire window with a new "scene" (removing the color buttons and adding a back button). This seems like a trivial task, but I can't find a solution in tutorials. Do I need to declare a new windows class with the back button and then have my button trap create a window of this class?

• OOP PHP make separate classes or one

  - by user2956219

  I'm studying OOP PHP and working on a small personal project but I have hard time grasping some concepts. Let's say I have a list of items, each item belongs to subcategory, and each subcategory belongs to category. So should I make separate classes for category (with methods to list all categories, add new category, delete category), class for subcategories and class for items? Or should I make creating, listing and deleting categories as methods for item class? Both category and subcategory are very simple and basically consist of ID, Name and parentID (for subcategory).
