  • Looking to create a website ... need assistance on what technologies to use!

    - by rsala004
    First off, My group and I don't have any experience with databases or anything of that sort, only programming (not web-programming), so this post is just me wondering what things I should start researching and possibly some referral to a hosting company. The abstract idea is to have a list of things, each categorized, and each item with user-submitted reviews (made by users who are signed up with the website). Would absolutely everything be stored on a SQL database? (the long text reviews for example) Does anyone have any suggestions on some 'web frameworks' we could use to jumpstart us? What should our absolute first step be? (I was thinking about first designing the basic database? so we have something to work around...?) Should we worry about which host we choose right now, any recommendations? (would it be a trivial task to switch hosts in the future?) Thanks again, any help is appreciated!

  • PHP or C++? I just want to choose a language and focus on it!

    - by user19177
    I love C++, but I feel I don't know if I should focus on web, so PHP, or C++. It's just an hard choice because right now I want to focus on one language and don't want to switch it a few months later. With C++ I'd program in SDL, while with PHP I don't know yet. I am not a very advanced programmer but I know basics of programming and can get going very well if determined. The problem is I just don't know.. I'm like OK! I'll go for C++! Then a minute later, wait what if I went with C#? Why this that.. ! I've read milion threads about C vs VB C# Python Ruby etc, all of them which I could find! It got me nowhere. The problem is probably I need to know something from some experts I guess.. I'm sure I'm not the only one who feels/felt like I do right now yeah? Uhm... I guess I might help you with some details so your answer may be easier to write! ( And also, if you want to say something else which is not related to PHP or C++, you can do that, I've just got to the conclusion that C++ and PHP are the ones that are worth it but yeah. C# I've discarded due to some stuff I read which says in future the projects I'd start now could just be useless and stuff like that.. ) Ok well : I'm 18 years old, and I program as hobby right now, but I do hope to go to a programming college in future. ( That would be in 2 years ). Hmm, I like programming games, and I'm mostly bothered by the fact "this language could be useless to what I need to do" ( I don't know how to explain this feeling! ) I don't know which other details I could add... I hope you guys can help me choose my path, this is really stressing me I'm wasting my time not doing anything right now because I don't know which language to use..! Thanks!

  • What should I learn next?

    - by Krysten
    I am a CS major. I've taken 2 courses in C (Intro to C and CS1) and 1 introductory course to OOP with Java. I really like Java and feel that I have a firm understanding of OOP concepts. I am really interested in web development and would like to learn a programming language that can be used to build dynamic web applications. My question is what language should I learn? I've narrowed it down to python or ruby. Also, I want to learn a programming language that will help me get a job upon graduating. So essentially, I will use this particular language to build applications that will help me get a job in the future.

  • The Ubuntu App Showdown -Specific software

    - by Stefanie
    I would like to participate the contest but I'm programming very specific scientific tools for the work in a molecular biological lab. I know that I won't win with such an app but it's a nice possibility to get into Qickly and Ubuntu Apps since I'm only programming for Windows at the moment. My question is, whether I have a possibility to explain what my software is doing and for what it is good in the lab. Also I have to provide some test data, that the jury can try it out. Is this possible and how I can submit those additional information?

  • In what way I can implement packet filtering function in C++/C#?

    - by Network study
    Background: I am going to design a firewall-like application (with GUI) which will include several functions such as Packet sniffing and packet filtering. Both of the functions should be implemented to support different protocol levels including application, transport, network and link layer. I only know a little in C#.Net programming to perform the IP packet sniffing. It is also known that packet filtering requires the techniques in WFP or LSP and packet sniffing in application requires dll hooking. Questions: I am not sure which programming language(either C++ or C#) would be suitable for designing such an application described above. If I want to implement the packet filtering function, any libraries will be needed? edit01: Someone suggest that winDivert would be helpful, is it true?

  • Should Equality be commutative within a Class Hierachy?

    - by vossad01
    It is easy to define the Equals operation in ways that are not commutative. When providing equality against other types, there are obviously situations (in most languages) were equality not being commutative is unavoidable. However, within one's own inheritance hierarchy where the root base class defines an equality member, a programmer has more control. Thus you can create situations where (A = B) ? (B = A), where A and B both derive from base class T Substituting the = with the appropriate variation for a given language. (.Equals(_), ==, etc.) That seems wrong to me, however, I recognize I may be biased by background in Mathematics. I have not been in programming long enough to know what is standard/accepted/preferred practice when programming. Do most programmers just accept .Equals(_)may not be commutative and code defensibly. Do they expect commutativity and get annoyed if it is not. In short, when working in a class hierarchy, should effort me made to ensure Equality is commutative?

  • Am I unhireable?

    - by DrSammyD
    I've received my B.S. in Software Engineering in August 2010 and I've been looking for a job since. I've gotten two interviews since that went up to the technical phone interview and then they were no longer interested. One of the recruiters mentioned to me that they thought my fundamentals weren't strong enough. What do I need to brush up on in order to get past the technical phone interview. My language of most experience is C#. I know Object Oriented Programming. I know what the difference between an interface and an abstract class is. I've applied to positions from game programming to WPF/Silverlight. I have a portfolio website www.samarmstrong.me. It also has my resume on there. I never had real internship. Am I unhireable?

  • Connection make b/w iphone to windows pc-rajay [on hold]

    - by Rajay
    I Need to create connection between ios to windows by using socket programming in ios. I'm trying to to use an application to communicate with Windows via sockets. At the minimum, I'm trying to at least figure out how I can create a connection from the iPhone (maybe using the iPhone to ping the Windows machine?) I'm not really clear on where I need to start. I'm pretty new to iOS development in general, and brand new to socket/network programming. I've tried several tutorials that haven't gotten me far. My goal is: Connect to a server via sockets (the server will be a Windows machine with a service waiting for incoming connections from the iPhone) If possible, I would like to write/build the client piece first, but I have been lost thus far. Hopefully the nice folks in the SO community can lend a hand and point me in the right direction.

  • Can you run OpenGL 2.0 on modern machines?

    - by thePalindrome
    I'm looking to get into 3d with OpenGL, using SDL to help with other stuff. I found plenty of good tutorials (lazyfoo is a big one), but "Learning Modern 3d Graphics Programming" uses a newer version of openGL that I'm not able to run! I opened up OpenGL extensions viewer, and I can only run OpenGL 2.0, whereas most tutorials are in higher versions. I ask this because I've heard that just about everything in 2.* got depreciated in the newer versions, so I'm worried that my code might not work. I'm looking at a few other tutorials, but I'm so used to SDL that those just confuse me... So should I bother trying to do graphics programming now, or should I just wait until I can upgrade my computer?

  • C# .NET 4.0 interactive course?

    - by Kanyhalos
    I would like to learn C# programming. I already studied it for several weeks and wrote some minor programs with VS2010, and I'm not completely newbie at programming because I worked on STALKER - Shadow of Chernobyl as scripter, but it was LUA. I want to become a real programmer. I think C# is a decent way to start with. I already learned about the most commonly used resource sites and got some nice eBooks as well, but unfortunately I don't have time to sit down in front my computer all the time, so my progress is pretty slow. I would like to ask that if someone can recommend me some decent interactive online courses to make my learning progress faster. I know about the "joe grip" course but I don't know if it's worth $39 also it's only for .NET 1.x and 2.0 while I'd like to learn 4.0 so I have no idea what should I do.

  • Ideas for how to structure a developer class/course? [on hold]

    - by Andy
    Let's say I need to teach a 3-8 week course in programming/development at a technical school (no kids) (regardless of language or technology and the target audience is beginners). I need ideas to make it a awesome class where I : Maximize the students learning and experience Make sure they don't fall a sleep Engage the students Make it exciting! I can always do traditional lecture+exercises and repeat this pattern over and over, but I think this is to old-school. Things I have considered to add to the course are: - Require pair programming - Code-review together with the students I would like suggestions on how to make a modern training class state really awesome?

  • Silverlight on Windows Phone

    This was a great announcement last week at MIX10: the programming model for the upcoming Windows Phone 7 is Silverlight!   For now it is Silverlight 3, with the possibility to use phone specific features: orientation location & map control (GPS) mic push notifications motion detection accelerometer compass light proximity contacts So we have the same programming model we already know, develop in Visual Studio, test with the built-in emulator or deploy...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • What is your personal learning process? [closed]

    - by yadvent
    I just wanted to say hello and ask a few simple questions. I have recently dove into programming with c# and have been curious what everyone else's experiences have been with when learning and starting out. What are some things that you can say that really have made a difference in your understanding and usages of any particular language? I lurk several forums but for some reason have always just kept to myself, and I've realized today that I'm not fully utilizing my resources when it comes to interacting with the community. With that being said, I realize that everyone that is interested in programming inherently is a natural problem solver and would like also to ask you to share your process of learning. Are you the type to have a short term project to tackle a general set of problems you're likely to encounter? Or are you a type of programmer that practices by zeroing in on a specific few problems you would like to solve? Any reply will be greatly appreciated Thank you :)

  • Any tips/tricks/resources on actually TEACHING a class on OOP? [closed]

    - by Sempus
    I may slowly be getting into teaching an Object-Orientated Programming class at my school in a year or two. I just graduated and work at my school as an Application Programmer. I'd first start off as a TA/grader and then slowly move into the Professor role. The class would be in Java. I always see resources on this fine site about HOW to program, but does anyone know any tips/tricks/resources on how to TEACH a programming class? It would be full of all different skills levels(but still semi-technical) so it would have to be a little more understandable than if it was just CS kids.

  • Looking for a previous post about skillsets for an embedded/firmware engineer. Can't find it anymore [closed]

    - by Sandiego
    I remember reading a post inquiring the basic/advanced skills required for embedded engineer works. The top comment divides the answer into two parts, the basic level/design level ,not purely coding(something like this...). Then another level : writing application(all about programming). For each level/category, the top comment talks about the necessary skills/knowledge/college courses(for me at least) . While I was searching for this post as I was trying to read it again, I found similar questions, but these are not the one I saw: http://stackoverflow.com/questions/1091931/what-skill-set-should-a-low-level-programmer-possess http://stackoverflow.com/questions/45247/how-do-i-get-started-in-embedded-programming http://electronics.stackexchange.com/questions/3343/how-to-become-an-embedded-software-developer Has anyone seen the post I'm talking about? This is a repost from Stackoverflow where I was told that this question is off-topic. So..please help guys

  • Recommended Books for OpenGL [closed]

    - by TheBlueCat
    I'm fairly new to OpenGL and I'm have been researching any books that would be beneficial, I've had suggested to me (I've finished reading the OpenGL Book online): Real Time Rendering GPU Gems 3 OpenGL Super Bible Does anyone know any other books that they've found useful in the past, even if it covers higher level algorithms. Also, can anyone suggest an IDE/Text Editor for Linux? I'm using Komodo and it's super buggy, I just booted into Windows today and tried Visual Studio and loved it, is their anything similar for Linux? Although, the books I've been reading are saying to not use IDEs, partly because of the reliance you place onto them, per se. I use Eclipse a lot for my Java programming, can I use C and OpenGL with that? Lastly, do you think it would be more beneficial staying on Windows and programming in C/OpenGL on their, I do like Linux, but I found Visual Studio to be pretty good in some aspects?

  • Please recommend me intermediate-to-advanced Python books to buy.

    - by anonnoir
    I'm in the final year, final semester of my law degree, and will be graduating very soon. (April, to be specific.) But before I begin practice, I plan to take 2 two months off, purely for serious programming study. So I'm currently looking for some Python-related books, gauged intermediate to advanced, which are interesting (because of the subject matter itself) and possibly useful to my future line of work. I've identified 2 possible purchases at the moment: Natural Language Processing with Python. The law deals mostly with words, and I've quite a number of ideas as to where I might go with NLP. Data extraction, summaries, client management systems linked with document templates, etc. Programming Collective Intelligence. This book fascinates me, because I've always liked the idea of machine learning (and I'm currently studying it by the side too, for fun). I'd like to build/play around with Web 2.0 applications; and who knows if I can apply some of the things I learn to my legal work. (E.g. Playground experiments to determine how and under what circumstances judges might be biased, by forcing algorithms to pore through judgments and calculate similarities, etc.) Please feel free to criticize my current choices, but do at least offer or recommend other books that I should read in their place. My budget can deal with 4 books, max. These books will be used heavily throughout the 2 months; I will be reading them back to back, absorbing the explanations given, and hacking away at their code. Also, the books themselves should satisfy 2 main criteria: Application. The book must teach how to solve problems. I like reading theory, but I want to build things and solve problems first. Even playful applications are fine, because games and experiments always have real-world applications sooner or later. Readability. I like reading technical books, no matter how difficult they are. I enjoy the effort and the feeling that you're learning something. But the book shouldn't contain code or explanations that are too cryptic or erratic. Even if it's difficult, the book's content should be accessible with focused reading. Note: I realize that I am somewhat of a beginner to the whole programming thing, so please don't put me down. But from experience, I think it's better to aim up and leave my comfort zone when learning new things, rather than to just remain stagnant the way I am. (At least the difficulty gives me focus: i.e. if a programmer can be that good, perhaps if I sustain my own efforts I too can be as good as him someday.) If anything, I'm also a very determined person, so two months of day-to-night intensive programming study with nothing else on my mind should, I think, give me a bit of a fighting chance to push my programming skills to a much higher level.

  • java.lang.ClassNotFoundException

    - by user341493
    Hey everyone, I have a java project that I'm working on which was working until a few days ago. I'm not sure what I did to my Eclipse set-up to hose it but now I'm getting a java.lang.ClassNotFoundException when I try to run some code that accesses the google finance api. I've built a small test application that uses the google finance api on its own and that seems to work. So, I think this is a project specific problem. Any help would be greatly appreciated.

  • Issue intercepting property in Silverlight application

    - by joblot
    I am using Ninject as DI container in a Silverlight application. Now I am extending the application to support interception and started integrating DynamicProxy2 extension for Ninject. I am trying to intercept call to properties on a ViewModel and ending up getting following exception: “Attempt to access the method failed: System.Reflection.Emit.DynamicMethod..ctor(System.String, System.Type, System.Type[], System.Reflection.Module, Boolean)” This exception is thrown when invocation.Proceed() method is called. I tried two implementations of the interceptor and they both fail public class NotifyPropertyChangedInterceptor: SimpleInterceptor { protected override void AfterInvoke(IInvocation invocation) { var model = (IAutoNotifyPropertyChanged)invocation.Request.Proxy; model.OnPropertyChanged(invocation.Request.Method.Name.Substring("set_".Length)); } } public class NotifyPropertyChangedInterceptor: IInterceptor { public void Intercept(IInvocation invocation) { invocation.Proceed(); var model = (IAutoNotifyPropertyChanged)invocation.Request.Proxy; model.OnPropertyChanged(invocation.Request.Method.Name.Substring("set_".Length)); } } I want to call OnPropertyChanged method on the ViewModel when property value is set. I am using Attribute based interception. [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = true)] public class NotifyPropertyChangedAttribute : InterceptAttribute { public override IInterceptor CreateInterceptor(IProxyRequest request) { if(request.Method.Name.StartsWith("set_")) return request.Context.Kernel.Get<NotifyPropertyChangedInterceptor>(); return null; } } I tested the implementation with a Console Application and it works alright. I also noted in Console Application as long as I had Ninject.Extensions.Interception.DynamicProxy2.dll in same folder as Ninject.dll I did not have to explicitly load DynamicProxy2Module into the Kernel, where as I had to explicitly load it for Silverlight application as follows: IKernel kernel = new StandardKernel(new DIModules(), new DynamicProxy2Module()); Could someone please help? Thanks

  • Is it possible that a single-threaded program is executed simultaneously on more than one CPU core?

    - by Wolfgang Plaschg
    When I run a single-threaded program that i have written on my quad core Intel i can see in the Windows Task Manager that actually all four cores of my CPU are more or less active. One core is more active than the other three, but there is also activity on those. There's no other program (besided the OS kernel of course) running that would be plausible for that activitiy. And when I close my program all activity an all cores drops down to nearly zero. All is left is a little "noise" on the cores, so I'm pretty sure all the visible activity comes directly or indirectly (like invoking system routines) from my program. Is it possible that the OS or the cores themselves try to balance some code or execution on all four cores, even it's not a multithreaded program? Do you have any links that documents this technique? Some infos to the program: It's a console app written in Qt, the Task Manager states that only one thread is running. Maybe Qt uses threads, but I don't use signals or slots, nor any GUI. Link to Task Manager screenshot: http://img97.imageshack.us/img97/6403/taskmanager.png This question is language agnostic and not tied to Qt/C++, i just want to know if Windows or Intel do to balance also single-threaded code on all cores. If they do, how does this technique work? All I can think of is, that kernel routines like reading from disk etc. is scheduled on all cores, but this won't improve performance significantly since the code still has to run synchronous to the kernel api calls. EDIT Do you know any tools to do a better analysis of single and/or multi-threaded programs than the poor Windows Task Manager?
