  • Which is the best pick?

    - by Daniel
    Hi, considering I have experience with Java SE: which language should I learn(and is best for that purpose) in order to build web applications some day with it? I have been contemplating PHP and Java EE. The latter does indeed seems as an obvious choice given my Java SE knowledge. But how does it fares in comparison with PHP and how good is it for the aforementioned purpose? If there is a better language for this purpose, feel free to recommend it. Thank you.

  • High level programming logic, design, pattern

    - by Muhammad Shahzad
    I have been doing programming from last 7 years, getting better and better, but still i think that am lacking something. I have been doing work in JOOMLA, MAGENTO, WP, Custom PHP, Opencart, laravel, codeignitor. Sometimes i need to design logic for a huge database application, in the applications we need nesting loops and queries, although i follow OOPS standards, ORM etc, still i feel i need more robust coding designs. I need to know how can i improve these things, so that code remain neat, efficient and faster. Also how big webapps like facebook twitter tests there code speed? How high level programmers choose design patterns. If you can help me find something useful with examples?

  • Object-oriented Programming - need your help

    - by wanderameise
    hey folks, I try to realize a little game project to dive deeper into OO programming (winforms c++/cli). I already started coding but now I´d like to make a re-design. For the beginning the game should consist of four parts like game-engine, user interface, highscore and playground. Heres a little (non-UML-conform) class diagramm to visualize my purposes http://i.imgur.com/lmpwj.png Would this be the right way? In my eyes the game engine is responsible to control the game sequences (state machine?) and exchanges information betweens all other classes. I appreciate any help!

  • What color scheme do you use for programming?

    - by EndangeredMassa
    I get a lot of attention at work because I am the only one who bothered to change the default color settings in Visual Studio. I just modified them myself. I can provide the settings file if anyone cares to import it. Here's an example of how it looks. It reminds me of DOS/BASIC programming before I actually knew how to program. I also find it to be very readable. What color schemes do you use?! EDIT: To clarify, I only edited the text settings. The windows and panels of VS2005 are still the windows default.

  • Need some advice on a language to use for a 'presentation display board'

    - by joe90
    As part of the project i am working on I am looking to produce some software that works on a LCD display (think call center info boards) and displays various graphs (the bars grow etc in realtime, so incoming call stats etc etc) and flicks between various 'plug-ins'. The problem is deciding what language to use.. I am thinking about using the XNA framework, as this will allow me to do some nice 3d effects, add a nice glow effect, play videos etc. I can have for example the company logo defused spinning slowly behind the current data display. I know however, the XNA framework is a bit left field for this. Or is there a better alternative? Thanks..

  • Refactor C++ code to use a scripting language?

    - by Justin Ardini
    Background: I have been working on a platformer game written in C++ for a few months. The game is currently written entirely in C++, though I am intrigued by the possibility of using Lua for enemy AI and possibly some other logic. However, the project was designed without Lua in mind, and I have already written working C++ code for much of the AI. I am hoping Lua can improve the extensibility of the game, but don't know if it would make sense to convert existing C++ code into Lua. The question: When, if ever, is it appropriate to take fully functional C++ code and refactor it into a scripting language like Lua? The question is intentionally a bit vague, so feel free give answers that are not relevant to the given background.

  • event vs thread programming on server side.

    - by AlxPeter
    We are planning to start a fairly complex web-portal which is expected to attract good local traffic and I've been told by my boss to consider/analyse node.js for the serve side. I think scalability and multi-core support can be handled with an Nginx or Cherokee up in the front. 1) Is this node.js ready for some serious/big business? 2) Does this 'event/asynchronous' paradigm on server side has the potential to support the heavy traffic and data operation ? considering the fact that 'everything' is being processed in a single thread and all the live connections would be lost if it got crashed (though its easy to restart). 3) What are the advantages of event based programming compared to thread based style ? or vice-versa. (I know of higher cost associated with thread switching but hardware can be squeezed with event model.) Following are interesting but contradicting (to some extent) papers:- 1) http://www.usenix.org/events/hotos03/tech/full_papers/vonbehren/vonbehren_html 2) http://pdos.csail.mit.edu/~rtm/papers/dabek:event.pdf

  • Excel - Programming Cells

    - by Andrew
    I just started programming in Excel and I have a problem figuring some code out. I have created a work schedule in Excel with lists in order to add new people. I wanted to create a macro in which the user inputs a value in a cell (I chose B3) and depending on that 'start time' in cell B3, the headers for the lists all change to correspond with that starting time. For example: B3 says 5:00 am. All the headers will follow with: 5:00 am, 6:00 am, 7:00 am, etc. of course the headers will move at some point so I'm wondering how do you point to a cell that moves too?

  • Reading programming tutorials while at work

    - by Teifion
    I work in a call centre and have been told by my manager that when there are no calls coming through they're happy for me to read stuff on the internet. There is a net filter in place but I can access SO from work which is always handy. I'm searching for articles that will make me a generally better programmer. I code in Python but combine it with Postgres and JS quite a lot if that helps. I'm currently reading Dive into python3 but I fear it won't last me much longer and would really like to expand my programming ability.

  • CLR - Common language runtime detected an invalid program in VS.NET

    - by Jimmy
    I have been using Visual Studio 2008 quite long but lately I am getting this message when I am developing an application in C#: Common language runtime detected an invalid program This happens when I try to enter to the properties of a component (text masked box properties, tool box property etc..). But it really became a problem when I tried to launch an other solution that I downloaded from the Developer's 5 star program of Microsoft and it didn't allowed me to launch at all and just got the same problem... I looked for the answer at google but just got some clues about people having the same vague error but in different situations like in ASP.NET I would appreciate any help with this issue... :( I do not want to reinstall VS, that will be my last resource... Update: I never figured out what the problem was so I installed a virtual machine with Windows XP on it, there I only have Visual Studio and Netbeans.

  • The D Programming Language for Game Development

    - by n2liquid
    Hi all, Recently I've been bothered because I reached a point in which C++ (even 0x) felt very limited, so I started looking for alternatives. Forget Java, C#, Python or Ruby. I still like the low-level nature of C++ and I'm not fond of virtual machines. Further, I'm a game engine developer, so I have to develop core routines which must be really fast, and lately I've been hungry for code expressiveness. C++ is an almost-there language for me, but there are many exceptions on how to use templates, and GCC isn't optimizing stuff as well as I'd hoped it would. So I'm considering to start learning D. Do you think it will suffice my needs as a game developer? I'm weary because I've never heard of D being used for that. Thanks!

  • WPF C#: Starting crash due to client 'Region and Language' settings

    - by FrieK
    Hi, I'm working on a WPF C# application, and it seems to crash with a few random people. So eventually I found out it was the 'Region and Language' settings that was responsible. For example, if I were to set my Format to English (United States) it will work, if I set it to Swedish (Sweden) it will crash from the start. When I test this in Visual Studio 2010 it gives error 'TypeInitializationException'. More precisely it does it here (it doesn't get passed the InitializeComponent() void): private void RadioButton_Checked(object sender, RoutedEventArgs e) { Info.SortOrder = SortBy.Rank; } It claims the error at the first line, which is just setting an enum value to a variable. I guess it's just doing it there because it's the first thing it makes, or something. Anyone has any idea how to fix this? I've searched around but can't seem to find out how :( Any help is much appreciated! Thanks

  • Cure for puzzle piece programming habbits?

    - by Recursion
    Even though I went to a decent CS school, I was still taught with the mentality of programming with puzzle pieces. By puzzle pieces I mean, looking up code segments at each step of the development process and adding them together as needed. Eventually gathering all of the pieces and having a properly working program. So as an example, if in my program the next step is to tokenize a string, I go to google and search "how do I tokenize a string in language". All instead of critically thinking about its implementation. I personally don't think its a very good way to program and I always seem to forget everything that I have searched for. So how can I get out of this puzzle piece mode of programmer that I was taught.

  • Is it best to code from a blank sheet or improving a code that's already written?

    - by user300371
    Just had a curious thought, but for general coding and programming, do you think it's best to work out all the logic yourself and start from a blank sheet or just take a code that has been written already(by you or someone else) and just change it to your liking? Assuming you have a programming background of like 1year+. (because as a beginner, it's best to learn from nothing) I'm not saying copy+paste someone else's code and say it's yours.

  • Game Server Language Selection

    - by mr.LiKaShing
    I am planning to make a online-multiplayer game with my friends. The game is a browser card game (so, players act in turns) and players could host rooms in a lobby. Flex + actionscript will be used to write for the client side. We are discussing what should be used for the server side. I suggested C#/Java and my friend suggested PHP. I kw there are couple of questions asking for what language to use but I think it should depend on specific conditions. Is there any suggestion for us? Thanks.

  • Movement in game programming

    - by hanesjw
    This question may have been asked before, but I'm starting to get into game programming on the Android. I'm having a hard time figuring out the best way to move an object. To put it simply, lets say I have a bitmap located on 0,0 and i want to move it across the screen. The obvious way to do it would be to simply increment the X position by one every time the Surface View onDraw method gets called. But what if I wanted to make it move faster? I could increment it by two or three instead of one, but then the movement starts to get really choppy and stupid looking. What is the best way to go about doing this?

  • Server Side code Pushing Data to client Browser while current thread is busy Comet (programming)

    - by h_power11
    Hello Friends, I am writing one simple web page with bunch of textboxes and a button control. Now when user finished editing the values on this text boxes user has to click the button and this button invoke heavily process intensive algorithm on server side code based on the data received from client (Textboxes) And it could some time takes up to 30 to 45 minutes to complete the whole operation so the current thread is still inside the button click event handler function. That background task only provides one event, and the web page subscribes to it to get some text data after each stage of processing I was wandering if there is any way I can keep user up-to-date with what is the current progress on that background task. I have div element to print the current status information So I am looking for some sort of reverse mechanism then "get" and "post". I have read some articles on the Comet (programming) but I can't find any easy or definitive answer Thanks in advance

  • Taking a break from programming harmful to career?

    - by Chris
    I'm currently taking a year out from University to do an internship at a large (well known) software vendor. I'll be returning to Uni next September for a year to finish my studies. I really want to take a year out after graduation, I won't be doing any programming in this year. Will this make me less competitive when applying for programmer jobs when I get back from my year away? I'm looking to work with the Microsoft technology stack, my internship has been all Java and Unix thus far. The assumption is I won't be taking up a full time offer with the company I interned at (despite the offer).

  • PHP MYSQL Insert Data in Arabic Language

    - by h_a86
    I am trying to insert some Arabic Language data into MySQL using PHP and an HTML form. When I insert the data in to MYSQL table, the table field represents data as مرحبا العالم. But when I access the same data with PHP and show it in my webpage, it shows the correct data. I am using: http-equiv="Content-Type" content="text/html; charset=utf-8" meta tag in my web page to show Arabic data. My question is why my data looks like this: مرحبا العالم in MySQL table, and how should I correct it.
