  • Machine Learning Algorithm for Peer-to-Peer Nodes

    - by FreshCode
    I want to apply machine learning to a classification problem in a parallel environment. Several independent nodes, each with multiple on/off sensors, can communicate their sensor data with the goal of classifying an event as defined by a heuristic, training data or both. Each peer will be measuring the same data from their unique perspective and will attempt to classify the result while taking into account that any neighbouring node (or its sensors or just the connection to the node) could be faulty. Nodes should function as equal peers and determine the most likely classification by communicating their results. Ultimately each node should make a decision based on their own sensor data and their peers' data. If it matters, false positives are OK for certain classifications (albeit undesirable) but false negatives would be totally unacceptable. Given that each final classification will receive good or bad feedback, what would be an appropriate machine learning algorithm to approach this problem with if the nodes could communicate with each other to determine the most likely classification?

  • Scripting Languages vs. Compiled Languages for web development

    - by Austin Hyde
    Though I come from a purely PHP background on the web development side of programming, I have also spent much time with C# and C++ on the desktop. I don't really want to spark any flame wars, but: When should you use scripting languages over compiled languages for website development? (and vice versa) Just to clarify, for the sake of this question, I define a "scripting language" to mean an interpreted language like PHP, Python, or Ruby, and a "compiled language" to mean a strongly typed, compiled language like C#, C++, Java, or VB.

  • Is LuaJIT really faster than every other JIT-ed dynamic languages?

    - by Gabriel Cuvillier
    According to the computer language benchmark game, the LuaJIT implementation seems to beat every other JIT-ed dynamic language (V8, Tracemonkey, PLT Scheme, Erlang HIPE) by an order of magnitude. I know that these benchmarks are not representative (as they say: "Which programming language implementations have the fastest benchmark programs?"), but this is still really impressive. In practice, is it really the case? Someone have tested that Lua implementation?

  • Multithreaded program in C: calculating thread stack space

    - by SlappyTheFish
    Situation: I am writing a program in C that maintains a number of threads. Once a thread ends, a new one is created. Each thread forks - the child runs a PHP process via exec() and the parent waits for it to finish. Each PHP process takes the next item from a queue, processes it and exits. Basic code: http://www.4pmp.com/2010/03/multitasking-php-in-parallel/ Problem: The PHP processes are Symfony tasks and Symfony requires a fairly huge amount of memory. How can I safely calculate the required stack space for each thread so that PHP processes will have enough memory? The memory limit set in php.ini is 128Mb so should I allocate this much space in the stack?

  • Objective-C Array/List Question

    - by Dave C
    What is the best practice, even in general programming, when you have an undefined, possibly infinite, amount of items that you need in an array but don't have defined bounds. Can you define an endless array in objective c that you can keep pushing items onto, like other lanaguages have a list item. Thanks for any help.

  • How to spin an independent dispacher thread for a Silverlight UserControl

    - by ondesertverge
    I am trying to move a lot of different elements by 1 pixel very often and in parallel. Trying to do this on one dispatcher thread means that the elements are visited one after another. The result is that the more elements I have the slower they will all move. In WPF I was able to use a HostVisual as described here to solve this. I can't seem to find anything similar in Silverlight. Is this a drawback of the lightweight framework or is there something I haven't stumbled upon yet? I am using SL4.

  • How do you write your QTP Tests?

    - by Josh Harris
    I am experimenting with using QTP for some webapp ui automation testing and I was wondering how people usually write their QTP tests. Do you use the object map, descriptive programming, a combination or some other way all together? Any little code example would be appreciated, Thank you

  • Recommended Clang command line options

    - by frou
    The Manual for Clang seems to be work in progress, so could you help me formulate the definitive command line options for compiling ANSI-C (AKA C89, C90) with maximum strictness and relevant/helpful warnings? Clang is a compiler front end for the C, C++, and Objective-C programming languages. It uses the Low Level Virtual Machine (LLVM) as its back end. It is still under development. Its goal is to offer a replacement to the GNU Compiler Collection (GCC)

  • Learning XNA for Game Development. Is it worth It?

    - by Nipuna Silva
    It seems that most of the popular games in the world are developed using C++. But Microsoft's game platform, XNA Studio is based on programming in C# and I didn't find any popular game which was developed using XNA. Also there are fewer Ebooks you find on XNA and even the google search for a problem won't give you much help. Does people doesn't use XNA as a gaming platform? Is it worth learning XNA for game development or should I consider some other platform?

  • Python Mindstorms RCX

    - by Kyle Schmidt
    I've got 30 unopened Lego Mindstorms kits that I'd love to use in my intro programming class to do some simple robotics stuff at the end of the year. We're using Python in the class, so I'd prefer there to be a way for the kids to write the programs in Python. Unfortunately, these are old kits with RCX bricks - not the newer NXT ones, so most of the projects like NXT_Python can't help me. Is there any way to make that happen?

  • Serialization with Qt

    - by Narek
    I am programming a GUI with Qt. In my GUI I have a huge std::map. And "MyType" is a class that has different kinds of filds. So, in a word, I want to serialize the std::map. How can I do that? Does Qt provides us with neccesary features? P.S. I would like to use std::map, NOT QMap.

  • How can I tell if a set of parens in perl code will act as grouping parens or form a list?

    - by Ryan Thompson
    In perl, parentheses are used for overriding precedence (as in most programming languages) as well as for creating lists. How can I tell if a particular pair of parens will be treated as a grouping construct or a one-element list? For example, I'm pretty sure this is a scalar and not a one-element list: (1 + 1) But what about more complex expressions? Is there an easy way to tell?

  • Dynamic UI vs Static UI

    - by Damien
    I've been wondering, at what point should I give up the convenience of a static data entry form with designer support for a dynamic UI which removes a lot of code duplication? There seems to be a conflict in the programming world where people constantly try to remove code repetition to improve maintainability and yet when it comes to forms, that all goes out of the window and everything gets added explicitly to the forms. What signs should I look for to know when it's time to leave the designer in the dust and create a dynamic UI?

  • Allow access to my server.

    - by Zachary Brown
    I have a server, did some of the programming myself. It ison my home network, but I need to be able to access it from anywhere over the internet. I have done the port forwarding like I am supposed to, but I still cant get to it from an outside computer. It just displays Internet Explorer cannot display the webpage. I don't know what else to do. I am on a Linksys WRT54G v8 router running ddWRT v24 micro firmware.

  • How to skip parentheses on Netbeans with enter?

    - by nunos
    So I have been programming in C++ with Eclipse and have the habit of hitting enter to skip parentheses (anyone who has ever used eclipse probably knows what I am talking about). I have recently started learning Java and decided to use NetBeans, mostly due to the much more simple interface. However, I would like to know if there a way to skip the (), [], < and "" on enter just like what happens in Eclipse in NetBeans. Thanks.

  • Why there is no open source framework (like Java) for C# application development?

    - by Calvin
    Hi, C# is much more popular than Java in recent years. As a general-purpose programming language, many people feel that C# is better designed than Java. Why until now there is no open source framework for C# application development? Why no one take the initiative to develop a open source framework for C# which is comparable to Java? (Many people say Mono is not a mature framework and should not be used in serious application development.) Calvin
