  • Emulate Historical Figures i.e. Einstein - Is this possible using linguistic logic for my http://www.ustimeline.com Education System

    - by Johnnylight
    After hearing about the success of IBM's Watson I started thinking perhaps emulating human language is now possible? My goal is to create Virtual Historical characters to represent the main characters in my Adventur-Cation The Great American Adventure program such as Einstein or Crazy Horse. The goal is to build an intelligent system capable of indexing the internet and storing the data using a schema using modern knowledge on linguistic theory (phonemes, morphemes, syntax) to build a system capable to returning a semantically sound response very similar to the response made by the same person if still alive today. The goal would be to use the same engine/system for all characters. Each characters would have their own digital representation and voice, and would organize data differently based on tags/keywords stored about the individual. Imagine a Max Headroom Einstein. Based on the success of Watson, I believe something like this may now be possible. Would be an interesting way to study history and would be a vehicle of entertainment as well. Can anyone confirm if this has already been attempted? Is anyone interested in exploring this using Cognitive Science, Psychology, Artificial Intelligence, Historical data captured on the internet, and Linguistic theory?

  • How do I simplify a 2D game grid for level management while keeping its by-pixel features?

    - by Eric Thoma
    (I cross-posted this from StackOverflow as this seems to be a more appropriate forum. I've looked around a little here and I did not find an answer, so I hope this is not a recurring question.) This is a question dealing with 2D world design. I am playing around by creating a 2D bird's eye view shooter game, and I am looking to make the game sleek and advanced. I hope to be able to write physics so projectiles have momentum and knock-down properties. I am immediately running into the problem of world design. I need a way to have level files that store everything there is about a game. This is easiest by just having a grid of objects. But there are thin-walls and other objects that don't seem to fit into a traditional cell of a grid. I want to be able to fit all these together so I can streamline level design; so I don't have to put in the exact pixel-specific start and end of a wall. There doesn't seem to be an obvious translation from level file to game without forcing myself into a pacman-life scenario, meaning a scenario where the game feels boxy and discrete. There is a contrast between the smoothly (relatively) moving characters and finite jumps in a grid. I would appreciate an answer that would describe implementation options or point me to resources that do. I would also appreciate references to sites that teach game design. The language I am using is Java (although I would love to use C or C++, but I can never find convenient resources in those languages). Thank you for any answers. Please leave any questions in the space below; I will be able to answer them later tonight (28th Nov).

  • Performing a Depth First Search iteratively using async/parallel processing?

    - by Prabhu
    Here is a method that does a DFS search and returns a list of all items given a top level item id. How could I modify this to take advantage of parallel processing? Currently, the call to get the sub items is made one by one for each item in the stack. It would be nice if I could get the sub items for multiple items in the stack at the same time, and populate my return list faster. How could I do this (either using async/await or TPL, or anything else) in a thread safe manner? private async Task<IList<Item>> GetItemsAsync(string topItemId) { var items = new List<Item>(); var topItem = await GetItemAsync(topItemId); Stack<Item> stack = new Stack<Item>(); stack.Push(topItem); while (stack.Count > 0) { var item = stack.Pop(); items.Add(item); var subItems = await GetSubItemsAsync(item.SubId); foreach (var subItem in subItems) { stack.Push(subItem); } } return items; } I was thinking of something along these lines, but it's not coming together: var tasks = stack.Select(async item => { items.Add(item); var subItems = await GetSubItemsAsync(item.SubId); foreach (var subItem in subItems) { stack.Push(subItem); } }).ToList(); if (tasks.Any()) await Task.WhenAll(tasks); The language I'm using is C#.

  • What is the recommended MongoDB schema for this quiz-engine scenario?

    - by hughesdan
    I'm working on a quiz engine for learning a foreign language. The engine shows users four images simultaneously and then plays an audio file. The user has to match the audio to the correct image. Below is my MongoDB document structure. Each document consists of an image file reference and an array of references to audio files that match that image. To generate a quiz instance I select four documents at random, show the images and then play one audio file from the four documents at random. The next step in my application development is to decide on the best document schema for storing user guesses. There are several requirements to consider: I need to be able to report statistics at a user level. For example, total correct answers, total guesses, mean accuracy, etc) I need to be able to query images based on the user's learning progress. For example, select 4 documents where guess count is 10 and accuracy is <=0.50. The schema needs to be optimized for fast quiz generation. The schema must not cause future scaling issues vis a vis document size. Assume 1mm users who make an average of 1000 guesses. Given all of this as background information, what would be the recommended schema? For example, would you store each guess in the Image document or perhaps in a User document (not shown) or a new document collection created for logging guesses? Would you recommend logging the raw guess data or would you pre-compute statistics by incrementing counters within the relevant document? Schema for Image Collection: _id "505bcc7a45c978be24000005" date 2012-09-21 02:10:02 UTC imageFileName "BD3E134A-C7B3-4405-9004-ED573DF477FE-29879-0000395CF1091601" random 0.26997075392864645 user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioFiles [ 0 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "English" date 2012-09-22 01:15:04 UTC } 1 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "Spanish" date 2012-09-22 01:17:04 UTC } ]

  • SharePoint 2013 Developer Ramp-Up - Part 2

    As stated already yesterday, today I continued with the available course material on Pluralsight. For sure interesting topics in the second part of the series but not the field of operation I'm going to work in later. During the course you get a lot of information about how to create and deploy SharePoint Solutions and hosted SharePoint Apps. Today's resource(s) Apart from some blog articles I watched in the following course today: SharePoint 2013 Developer Ramp-Up - Part 2 - Developing SharePoint Solutions and Apps Not thrilling but still two solid hours to go. Takeaway One of the coolest aspects I figured out today is that SharePoint development can be done easily in JavaScript and C# - just as you like or prefer. It's actually pretty cool to see that you could integrate external JS libraries like datajs, knockout,js and so forth in order to implement your solution. And that you should be very familiar with Microsoft PowerShell. Not only to simplify some repetitive work but also to do be able to get things going in SharePoint. Having a decent background knowledge in Linux, I find this pretty amusing and remember the initial baby steps when PowerShell was introduced some years back (Note: German language). The outcry as well as the hype was too funny. Honestly, I have kind of mixed feelings about today's progress. Surely, there was interesting information about developing extensions directly for and in SharePoint... Hm, I'll leave that one for now and probably it might be helpful someday.

  • Finding the best practice for a game simulating tool

    - by Tougheart
    I'm studying Java right now, and I'm thinking of this tool as my practice project. The game is "League of Legends" in case anyone knows it, I'm not actually simulating the game as in simulating game play, I'm just trying to create a tool that can compare different champions to each other based on their own abilities and items bought inside the game. The game basics are: Every player has a champion in a team of 5 players playing against another team. Each champion has a different set of abilities (usually 4) that s/he uses to do damage to opposing champions. Each champion gets stronger by buying different items, increasing the attack it deals or decreasing the damage received. What I want to do is to create a tool to be used outside the game enabling players to try out different builds for their champions and compare the figures against other champions they usually fight against. The goal is to enable players get a deeper understanding of the different item combinations (builds) that can be used during the games, instead of trying them out in real games which can be somehow very time consuming. What I'm stuck at is the best practice I should follow to make this possible using Java, I can't figure out which classes should inherit from which, should I make champions and items specs in the code or extracted from other files, specially that I'm talking about hundreds of items and champions to use in that tool. I'm self studying Java, and I don't have much practice at it, so I would really appreciate any broad guidelines regarding this, and sorry if my question doesn't fit here, I tried to follow the rules. English isn't my native language, so I'm really sorry if I wasn't clear enough, I would be more than happy to explain anything that's not understood.

  • Matrices: Arrays or separate member variables?

    - by bjz
    I'm teaching myself 3D maths and in the process building my own rudimentary engine (of sorts). I was wondering what would be the best way to structure my matrix class. There are a few options: Separate member variables: struct Mat4 { float m11, m12, m13, m14, m21, m22, m23, m24, m31, m32, m33, m34, m41, m42, m43, m44; // methods } A multi-dimensional array: struct Mat4 { float[4][4] m; // methods } An array of vectors struct Mat4 { Vec4[4] m; // methods } I'm guessing there would be positives and negatives to each. From 3D Math Primer for Graphics and Game Development, 2nd Edition p.155: Matrices use 1-based indices, so the first row and column are numbered 1. For example, a12 (read “a one two,” not “a twelve”) is the element in the first row, second column. Notice that this is different from programming languages such as C++ and Java, which use 0-based array indices. A matrix does not have a column 0 or row 0. This difference in indexing can cause some confusion if matrices are stored using an actual array data type. For this reason, it’s common for classes that store small, fixed size matrices of the type used for geometric purposes to give each element its own named member variable, such as float a11, instead of using the language’s native array support with something like float elem[3][3]. So that's one vote for method one. Is this really the accepted way to do things? It seems rather unwieldy if the only benefit would be sticking with the conventional math notation.

  • How should an undergraduate programmer organize his time learning the maximum possible?

    - by nischayn22
    I started programming lately(pre-final year of a CS degree) and now feel like there's a sea of uncovered treasure for me out there. So, I decided to cover as much as is possible before I look out for a job after graduation. So, I started to read books (The C++ Programming Language, Introduction to Algorithms, Cracking the Coding Interview, Programming Pearls,etc ) participate in StackExchange sites, solving problems (InterviewStreet and ProjectEuler), coding for open source, chatting to fellow programmers/mentors and try to learn more and more. Good,then what's the problem?? The problem is I am trying to do many things, but I am doubtful that I am still utilizing my time properly. I am reading many books and sometimes I just leave a book halfway (jumping from one book to another), sometimes I spend way too much time on chatting and also in getting lost somewhere in the huge internet world, and lastly the wasteful burden of attending classes (I don't think my teachers know good enough or I prefer learning on my own) May be some of you had similar situation. How did you organize your time? Or what do you think is the best way to organize it for an undergraduate? Also what mistakes am I making that you can warn me of

  • 25 years old and considering a career change...possible? practical?

    - by mq330
    Hi all, I'm new to this site and new to programming as well. I've spent some time going through an intro cs book that uses python as the language of choice. I find the exercises interesting and engaging and I generally have had a favorable experience programming so far. I've gone through some of the basics with python like writing simple programs, basics of GUIs, manipulating strings, lists, defining functions, etc. And I've always loved technology. Although I've never done any real hardcore programming yet, I was inclined to building websites from a very young age but I never really developed my skills. Now, the thing is I'm 25, I have my bacholors in environmental studies and two masters degrees in urban planning and landscape architecture respectively. I know, it would be quite a departure to pursue a career in programming at this point. Currently, I'm working as a geographic information systems intern. I've taken some GIS classes and have a lot of experience with making maps, doing spatial analysis etc. So what I'm thinking is maybe I can learn some solid programming skills and apply these skills in the field of GIS. From what I've seen, .net languages are the norm in this arena. Could you perhaps provide some guidance to me in terms of what languages I should focus on or courses I should take at this point? What about for building web mapping applications? Also, I was thinking about getting a certificate in programming from a university extension program. Do you think it would be worth it? And furthermore, do you think potential employers would be interested in hiring someone like me (once I get a couple of languages down pretty well) as an intern or in an entry level position? I'll be living in the bay area so I feel that there should be decent opportunities even though I don't have a b.s. in cs.

  • What's the best way to manage reusable classes/libraries separately?

    - by Tom
    When coding, I naturally often come up with classes or a set of classes with a high reusability. I'm looking for an easy, straight-forward way to work on them separately. I'd like to be able to easily integrate them into any project; it also should be possible to switch to a different version with as few commands as possible. Am I right with the assumption that git (or another VCS) is best suited for this? I thought of setting up local repositories for each class/project/library/plugin and then just cloning/pulling them. It would be great if I could reference those projects by name, not by the full path. Like git clone someproject. edit: To clarify, I know what VCS are about and I do use them. I'm just looking for a comfortable way to store and edit some reusable pieces of code (including unit tests) separately and to be able to include them (without the unit tests) in other projects, without having to manually copy files. Apache Maven is a good example, but I'm looking for a language-independent solution, optimally command-line-based.

  • Find possible variations of one item out of multiple baskets.

    - by tugberk
    I have three baskets of balls and each of them has 10 balls which have the following numbers: Basket 1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Basket 2: 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 Basket 3: 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 What would be the possible variations If I were to pick one ball from each basket? I guess this is called as Probability in Mathematics but not sure. How would you write this code in C# (or any other programming language) to get the correct results? Edit: Based on @Kilian Foth's comment, here is the solution in C#: class Program { static void Main(string[] args) { IEnumerable<string> basket1 = new List<string> { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10" }; IEnumerable<string> basket2 = new List<string> { "11", "12", "13", "14", "15", "16", "17", "18", "19", "20" }; IEnumerable<string> basket3 = new List<string> { "21", "22", "23", "24", "25", "26", "27", "28", "29", "30" }; foreach (var item1 in basket1) foreach (var item2 in basket2) foreach (var item3 in basket3) { Console.WriteLine("{0}, {1}, {2}", item1, item2, item3); } Console.ReadLine(); } }

  • Trying to move away from PHP/Yii: RoR, Python/Django or ASP.NET MVC? Your opinions please [closed]

    - by Örs
    I have a CS degree and I've been working as a web developer (front & backend) for about 2 years now. I've been working with PHP mostly because it was easy to pick up and find a job, but I've grown to dislike the language and want to try something new, and possibly get a better paying job. That last point is especially important because in my area (Romania/Eastern Europe) PHP jobs are mostly for people fresh out of college/high school, hence the pay is rather low. I've been working with the Yii framework which, if I understand correctly, borrows a lot from Ruby on Rails (convention over configuration, MVC, Active Record, scaffolding). Other than PHP I only know curly-brace languages (C/C++/Java) and bash so Python/Ruby might be a bit challenging. On the other hand I've been using Linux (with vim and recently Sublime Text 2) for almost 4 years now so Windows and a lack of a terminal would have its downsides as well. I'm leaning towards Python/Ruby because of my *nix bias (plus both look like fun), but I've heard great things about ASP.NET MVC as well. Any suggestions? PS: I think there are more jobs in ASP.NET around here, but that's not necessarily a plus, because there are a lot of CS graduates as well. tl;dr: Romanian PHP/Yii developer trying to move to Python/Django or Ruby/Rails or C#/ASP.NET MVC. Suggestions?

  • Clutter for game GUI

    - by tjameson
    I'm pretty new to game development, having only written a simple 3d game for a class project, but I'd like to get started on a bigger project. I'm writing an MMORPG to run in both the browser (WebGL) and natively (OpenGL ES 2). In choosing a GUI toolkit, I'm trying to find a style that work work natively and would be simple to emulate in WebGL. I am considering using D or Go for writing my game, so interfacing with C++ libraries will be difficult, if not impossible. Of course, the language isn't the end goal here, so if using C++ will save considerable time, I'll bite the bullet and use that. In order to reduce the amount of code I'll have to write for the browser, I'm considering using something simple like Clutter for basic abstractions, which I think will be pretty easy to emulate (layered canvases maybe?). Does anyone have experience using Clutter for a 3d game? Note: I haven't used any game development libraries, and I only have limited experience with GUI libraries. I do have HTML+CSS experience, so maybe librocket is a viable solution?

  • Material System

    - by Towelie
    I'm designing Material/Shader System (target API DX10+ and may be OpenGL3+, now only DX10). I know, there was a lot of topics about this, but i can't find what i need. I don't want to do some kind of compilation/parsing scripts in real-time. So there some artist-created material, written at some analog of CG. After it compiled to hlsl code and after to final shader. Also there are some hard-coded ConstantBuffers, like cbuffer EveryFrameChanging { float4x4 matView; float time; float delta; } And shader use shared constant buffers to get parameters. For each mesh in the scene, getting needs and what it can give (normals, binormals etc.) and finding corresponding permutation of shader or calculating missing parts. Also, during build calculating render states and the permutations or hash for this shader which later will be used for sorting or even giving the ID from 0 to ShaderCount w/o gaps to it for sorting. FinalShader have only 1 technique and one pass. After it for each Mesh setting some shader and it's good to render. some pseudo code SetConstantBuffer(ConstantBuffer::PerFrame); foreach (shader in FinalShaders) SetConstantBuffer(ConstantBuffer::PerShader, shader); SetRenderState(shader); foreach (mesh in shader.GetAllMeshes) SetConstantBuffer(ConstantBuffer::PerMesh, mesh); SetBuffers(mesh); Draw(); class FinalShader { public: UUID m_ID; RenderState m_RenderState; CBufferBindings m_BufferBindings; } But i have no idea how to create this CG language and do i really need it?

  • Is Apple getting out of the general purpose development platform business?

    - by Charles E. Grant
    I've been doing general ANSI C/Console C++/Java/Web development on Mac hardware for about ten years. I make no claims of objective superiority over other platforms, it just satisfies my personal tastes. With the success of the iPhone and the related App store there was some speculation that Apple would get out of the general purpose computer market, and become a closed software ecosystem, focusing on consumer appliances. I pooh-poohed the speculation at the time, but this week Apple announced that a) they were opening an App store for the Mac, b) Java applications would not be eligible for the App store, c) the Apple JVM was being deprecated and might not be available for future releases of OS X. I'm not a Java developer per se, but I work in a research lab that occasionally writes Java applications, and also depends on tools written Java. This has the potential to be a huge pain in the butt for us. As of now, there is no other JVM for OS X that we can point our end users to. Soy Latte and OpenJDK might be appropriate for developers, but the complexity of the installation makes them inappropriate for end users. Eventually I expect Oracle/SUN will produce a replacement JVM for OS X. More worrisome to me is that Apple used to specifically advertise that it was an excellent platform for scientific development, because they supported all major language platforms. Is the deprecation of their JVM a sign that this market no longer interests them?

  • XSLT and possible alternatives [on hold]

    - by wirrbel
    I had a look at XSLT for transforming one XML file into another one (HTML, etc.). Now while I see that there are benefits to XSLT (being a standardized and used tool) I am reluctant for a couple of reasons XSLT processors seem to be quite huge / resource hungry XML is a bad notation for programming and thats what XSLT is all about. It do not want to troll XSLT here though I just want to point out what I dislike about it to give you an idea of what I would expect from an alternative. Having some Lisp background I wonder whether there are better ways for tree-structure transformations based upon some lisp. I have seen references to DSSSL, sadly most links about DSSSL are dead so its already challenging to see some code that illustrates it. Is DSSSL still in use? I remember that I had installed openjade once when checking out docbook stuff. Jeff Atwood's blog post seems to hint upon using Ruby instead of XSLT. Are there any sane ways to do XML transformations similar to XSLT in a non-xml programming language? I would be open for input on Useful libraries for scripting languages that facilitate XML transformations especially (but not exclusively) lisp-like transformation languages, or Ruby, etc. A few things I found so far: A couple of places on the web have pointed out Linq as a possible alternative. Quite generally I any kind of classifications, also from those who have had the best XSLT experience. For scheme http://cs.brown.edu/~sk/Publications/Papers/Published/kk-sxslt/ and http://www.okmij.org/ftp/Scheme/xml.html

  • Using R on your Oracle Data Warehouse

    - by jean-pierre.dijcks
    Since it is Predictive Analytics World in our backyard (or are we San Francisco’s backyard…?) I figured it is well worth the time to dust of some old but important news. With big data (should we start calling it “any data analytics” instead?) being the buzz word and analytics the key operative goal, not moving data around is becoming more and more critical to the business users. Why? Because instead of spending time on moving data around into your next analytics server you should be running analytics on those CPUs. You could always do this with Oracle Data Mining within the Oracle Database. But a lot of folks want to leverage R as their main tool. Well, this article describes how you can do this, since 2010… As Casimir Saternos concludes in the article; “There is a growing awareness of the need to effectively analyze astronomical amounts of data, much of which is stored in Oracle databases. Statistics and modeling techniques are used to improve a wide variety of business functions. ODM accessed using the R language increases the value of your data by uncovering additional information. RODM is a powerful tool to enable your organization to make predictions, classify data, and create visualizations that maximize effectiveness and efficiencies.” Happy Analysis!

  • Should I learn the easier framework as a start? [closed]

    - by gunbuster363
    I've been a programmer for 2 years. I learned Java SE, C from college and learned Cobol from the workplace. I've noticed that there is a hype about framework and I actually don't know what is a framework. It is so cool that my colleague once said you cannot find a new job without knowing something like struct spring hibernate. And we should know Java EE too because it was aimed for enterprise application. I've never code something such as server-client web application, and I think I need to try it out. But which language should I code in? I can't decide between the following 2: 1) Java. It is heavily used by many company so I could easily reuse the experience gained. But Java and its related framework are pretty heavy (for the machine and operation). It is on-demand. 2) ROR. It is cool. The syntax of ruby is simple. I can get a better hand on it. And maybe I can learn the concept easily and possibly correctly. However, not much company here would use it. All the job ads are about J2EE/C#. Should I learn the easy one or the difficult one? Not to mention there are a lot of frameworks out there for Java, which makes the decision much more difficult.

  • Good practices when optimizing HTML5/Javascript Game Developement [closed]

    - by hustlerinc
    I'm just starting out as a game developer and have created a few crappy but playable clones of classic games like pong, and bomberman. Being self taught (bless the internet) I do this by just stuffing in code to make the games work. Now I feel the time has come to create something complete, for this I need to know how a game is structured. I've searched on the web but there isn't that much to be found. The only "high-level" language I know is javascript so reading a tutorial or article based on C++ doesn't help me that much. I'm looking for good resource's pedagogically covering the theory and possibly examples (in Javascript or pseudo code that is understandable for a beginner) of how the game pieces fit together. From the start screen to asset loading and running the game loop. I'm not looking for anything complicated like reading through a 4000 line source code. All I want to learn is where, how and when the main parts of every game should be called. If you know any good resources to share, or maybe even have an answer for me I would deeply appreciate it.

  • Necessary Infrastructure for large project with many components communicating through IPCs

    - by jluzwick
    I have a fairly in depth question which probably doesn't have an exact answer. As a software engineer, I am usually tasked with working on a program or project with minimal understanding of how other components or programs in the project interact with each other. When one program fails in a sea of multiple components and processes, what infrastructure elements are necessary to ensure that the problem can be accurately tracked to the violating application? More specifically, what infrastructure elements should be necessary for this large project and which are optional but very helpful. One such example I can think of is some form of a common logging infrastructure that allows for a developer or tester to easily browse through a log that contains numerous components for messages that might allude to the culprit program along with a "trail" of what happened before the issue occurred. I'm thinking of something similar to Androids alogcat tool. These necessary infrastructure elements should be language-agnostic. While these elements should be understood by all engineers on the team in question, which elements should be understood at great detail by the technical system engineers and what should the individual software engineers be responsible for adding to their tools to allow for such infrastructures to take hold? Please feel free to ask for clarification if something does not make sense as I understand this question is very broad and needs some refinement. I will refine as necessary from the answers and comments I receive. Thanks for any help!

  • Where to find common database abbreviations in Spanish

    - by jmh_gr
    I'm doing a little pro bono work for an organization in Central America. I'm ok at Spanish and my contacts are perfectly fluent but are not techincal people. Even if they don't care what I call some fields in a database I still want to make as clean a schema as possible, and I'd like to know what some typical abbreviations are for field / variable names in Spanish. I understand abbreviations and naming conventions are entirely personal. I'm not asking for the "correct" or "best" way to abbreviate database object names. I'm just looking for references to lists of typical abbreviations that would be easily recognizable to a techincally competent native Spanish speaker. I believe I am a decent googler but I've had no luck on this one. For example, in my company (where English is the primary language) 'Date' is always shortened to 'DT', 'Code' to 'CD', 'Item' to 'IT', etc. It's easy for the crowds of IT temp workers who revolve through on various projects to figure out that 'DT' stands for 'Date', 'YR' for 'Year', or 'TN' for 'Transaction' without even having to consult the official abbreviations list.

  • What to learn after standard C++?

    - by Luca Cerone
    I switched to C++ a few months ago, learning its syntax, the main features of the STL and what you can usually find in a "learn C++" manual. Now I would like to go further. What would be your recommendations? I would like to know what to learn next (not only about the language, but also debugging, frameworks etc. etc.) I know probably the answer depends on the specific needs of each user, so here is a list of mine: Cross Platform development Developing GUI for my programs Develop extendible software, allowing the use of plugins Use of scientific libraries Interact with databases (mainly MySQL) Having server/client functionalities (I'd like users of my programs to interact through internet.. as you might have guessed I am not a programmer by training so I might have used the wrong terms.. if so I apologize for that). Of course I know it takes time, but I would like to have a good list of references and resources to start (both books and websites are ok). Thanks a lot for your help!

  • Is the Entity Component System architecture object oriented by definition?

    - by tieTYT
    Is the Entity Component System architecture object oriented, by definition? It seems more procedural or functional to me. My opinion is that it doesn't prevent you from implementing it in an OO language, but it would not be idiomatic to do so in a staunchly OO way. It seems like ECS separates data (E & C) from behavior (S). As evidence: The idea is to have no game methods embedded in the entity. And: The component consists of a minimal set of data needed for a specific purpose Systems are single purpose functions that take a set of entities which have a specific component I think this is not object oriented because a big part of being object oriented is combining your data and behavior together. As evidence: In contrast, the object-oriented approach encourages the programmer to place data where it is not directly accessible by the rest of the program. Instead, the data is accessed by calling specially written functions, commonly called methods, which are bundled in with the data. ECS, on the other hand, seems to be all about separating your data from your behavior.

  • Is it viable to make a port from a C++ application to Java through LLVM

    - by Javier Mr
    how viable is it to port a C++ application to Java bytecode using LLVM (I guess LLJVM)? The thing is that we currently have a process written in C++ but a new client has made mandatory to been able to run the program in a multiplatform way, using the Java Virtual Machine with obviously no native code (no JNI). The idea is to be able to take the generated jar and copy then to different systems (Linux, Win, 32 bits - 64 bits) and it should just work. Looking around looks like it is possible to compile C++ to LLVM IR code and then that code to java bytecode. There is no need of the generated code to be readable. I have test a bit with similar things using emscripten, this takes C++ code and compile it to JavaScript. The result is valid JS but totally unreadable (looks like assambler). Does anybody done a port of an application from C++ to Java bytecode using this tecnique? What problems could we face? Is a valid approach for production code? Note: I am aware that currently we have some non standard C++ and close source libraries, we are looking to removing this non standard code and all close source libraries and use Free Libre Open Source Software, so lets suppose all code is standard C++ code with all code available at compile time. Note: It is not an option to write portable C++ code and then compile it to the desired target platform, the compiled program must be mltiplatform thus the use of JVM (right now we are not looking in similar solutions but Python or other language base, but i would also like to heard about it)
