  • Does any method exist quickly to detect valid range versions of used library

    - by daneel-yaitskov
    I'm a beginner Haskell programmer. I have written some useful code for the last six month. And I want to release a library from it. The code will use system installation cabal as any Haskell library. A library is released with cabal has a meta data file where there is a logical predicate from the libraries and their versions. A developer usually uses one set libraries. It tediously care a set of the sets libraries. How to know either my library is compiled successfully or not for some subset libraries?

  • jQuery.Form wont submit

    - by kim
    Im´trying to submit a form without refreshing the page, but I´m having a problem. When I click submit the page refreshes and anothing gets posted. Here is the code, what am I doing wrong? (I´m a newbie) jQuery 1.4.2 and the jQuery Form Plugin 2.43 is present. tnx $(document).ready(function() { var options = { target: '#output2', url: https://graph.facebook.com/<%=fbUid%>/feed, type: post, clearForm: true // clear all form fields after successful submit //dataType: null // 'xml', 'script', or 'json' (expected server response type) //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; // bind to the form's submit event $('#fbPostStatus').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); });

  • Connect Android application to remote data

    - by tadywankenobi
    Sheesh talk about limited information! I'm trying to get my Android application to connect to an online database to access information. There's quite a bit of info including geotags and these are going to be mapped on my app. The developer site has the very informative piece of information: You can use the network (when it's available) to store and retrieve data on your own web-based services. To do network operations, use classes in the following packages: java.net.* android.net.* Like I said in my previous question, I'm still very much an android newbie, and trying to remember my java oop from college is slow. Does anyone have an example of how this might work, or how I could implement it? I wouldn't mind even connecting to a local xml file, if I could find a good example of how to do that!? Am I just looking in all the wrong places?! Help. Please! T

  • Maven overlay with war not generated by maven

    - by dnc253
    I'm pretty new to Maven, so I apologize if this is a newbie question. We are trying to integrate a 3rd-party app into ours. This 3rd-party functionality is delivered to us as a war file. As part of this integration, I want to add some extra jars and and a properties file. Googling around, I discovered overlays. However, in all the examples I've seen, it looks the the wars that are being overlayed, were themselves generated by Maven, and thus Maven can figure out dependencies, conflicts, etc. between the two. I'm just wondering if there's a way for me to overlay this 3rd-party war with this extra stuff I want. If so, what would that look like in the pom.xml?

  • Which is the future of web development: HTML5 or Silverlight(or other RIA framework)?

    - by Morgan Cheng
    My colleagues have a heated debate on what is the future of web development. One side is supporting HTML5 and the other is supporting Silverlight. There is no conclusion of the debate yet. In my humble opinion as a programmer, HTML5 will not improve programming productivity, while Silverlight will. In my understanding, programmers still need to program in JavaScript to take advantage of HTML5. For Silverlight, we can use C# which is static-type language. A lot of coding defects can be found in compilation time. For HTML5, different browsers might still have different behavior even though there is spec. For Silverlight, generally what works in IE will work the same way in other browsers. Just my thoughts. Any idea on how to choose future direction of web development?

  • PHP: How to check for response code?

    - by Tom
    Hi, I'm a relative PHP newbie implementing a PayPal IPN listener and all seems to be working fine, except I dont really know how to check for a response code. I've tried something ugly with cURL but it doesn't work at all (I'm not understanding cURL). I've tried this piece of code that I grabbed from somewhere on the net: $fp = fsockopen('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30); $response_headers = get_headers($fp); $response_code = (int)substr($headers[0], 9, 3); ... but it's not working (returns $response_code = 0). So right now, I'm debugging my IPN code without checking for a Response 200. Can anyone more experienced advise me on what's the proper/simple way to check this? Thanks

  • What programming languages do you consider indispensable in your experience?

    - by Federico Ramponi
    Each programming language comes with its concepts, best practices, libraries, tools, community, in one word: culture. Learning more than one programming language will make you a better programmer, for the more concepts you learn, the faster you will feel comfortable when the next language or technology will come. Mine, so far, are C, some C++, and Python, and many times I read that it would be worth learning LISP, for "the profound enlightenment experience you will have when you finally get it" (quoting Eric Raymond). My questions are: Which is the next one you would consider a good investment to learn? Of the many programming languages you have learnt and worked with, which ones do you consider to be an essential part of one's CS culture, and why? EDIT. Further question: is there any language you would sincerely advise to avoid as a waste of time? (The famous, and questionable, slatings in this letter from Dijkstra come to my mind.)

  • What things didn't you know you needed but are now very glad you have?

    - by DrStalker
    Take a programmer that has never used source control, show them what it does, and their eyes light up... the benefits are obvious but until they actually see it most people had never considered the existence of such a tool. What other such things exist? Tools or approaches or techniques that aren't obvious before you encounter them, but once seen have obvious value. Things that are likely so ingrained in the way you work that it's hard to think of working without them, things almost embarrassing to bring up because you expect the other person to say "duh, that's obvious!" No matter how petty something seems there is a chance that other people don't know about it yet; I'd like to get an idea on what things I'm missing simply because I never thought of them.

  • Why isn't my favicon appearing in IE7/8?

    - by X3Maverick
    Page of interest: https://www.gsb-yourbank.com/test/ ICO file: https://www.gsb-yourbank.com/test/favicon.ico My favicon is a 16x16 resolution, 16-color ICO file. It will not appear in IE 7/8 no matter what I do! I've tried everything I can think of, including: generating the ICO with a variety of different utilities, changing the syntax of the favicon link elements in the document head, using absolute, relative, and root-relative URLs in the favicon link elements, using a PNG instead of an ICO file, ensuring that I am uploading the file via FTP in binary mode, As a longtime web developer/programmer, I can't believe that this is tripping me up. Any help would be greatly appreciated.

  • what changes when your input is giga/terabyte sized?

    - by Wang
    I just took my first baby step today into real scientific computing today when I was shown a data set where the smallest file is 48000 fields by 1600 rows (haplotypes for several people, for chromosome 22). And this is considered tiny. I write Python, so I've spent the last few hours reading about HDF5, and Numpy, and PyTable, but I still feel like I'm not really grokking what a terabyte-sized data set actually means for me as a programmer. For example, someone pointed out that with larger data sets, it becomes impossible to read the whole thing into memory, not because the machine has insufficient RAM, but because the architecture has insufficient address space! It blew my mind. What other assumptions have I been relying in the classroom that just don't work with input this big? What kinds of things do I need to start doing or thinking about differently? (This doesn't have to be Python specific.)

  • What would be the simplest way to deal with a text file using JSP?

    - by Nano Taboada
    First and foremost I should acknowledge that I have no experience at all using Java ServerPages, but I'm positive about achieving this task if you guys help me out a bit since it doesn't seem like something difficult for a seasoned JSP programmer. Anyway the thing is, there's an actual running JSP application within a *NIX box which I somewhat administer with kind of good permissions. The idea is to create a new but dead simple JSP page to control some Korn Shell scripts I've got running there. So the goal is to make some sort of HTML form that will be writing some kind of scriptStatus.on / scriptStatus.off file: #!usr/bin/ksh # coolScript.sh # This is my cool script that is being launched by cron every 10 minutes. if [ -e scriptStatus.off ] then # monitor disabled else # monitor enabled fi which then can be checked for existence within the running script, therefore allowing to easily activate / deactivate it without actually have do deal with cron. Please let me know if all this does make any sense and don't hesitate to ask as much questions as needed. Thanks much in advance!

  • Does anyone else think instance variables are problematic in database-backed applications?

    - by Ben Aston
    It occurs to me that state control in languages like C# is not well supported. By this, I mean, it is left upto the programmer to manage the state of in-memory objects. A common use-case is that instance variables in the domain-model are copies of information residing in persistent storage (i.e. the database). Clearly this violates the single point of authority principle, and "synchronisation" has to be managed by the developer. I envisage a system where instead of instance variables, we have simple public access/mutator methods marked with attributes that link them to the database, and where reads and writes are mediated by a framework that decides whether to hit the database. Does such a system exist? Am I completely missing the point, or is there some truth to this idea?

  • How to avoid Modal Storyboard infinite loop

    - by misthills
    I've written a number of iOS applications a year ago on an old version of Xcode. I've just started a new project and discovered the storyboard feature in the latest Xcode. It turns out this is perfect for the application I am writing as it consists of ~30 interlinked screens. My question is, how do I structure my storyboard and segues to allow my application to follow a circular path through my screens. I have seen a number of examples that simply segue screen 1 to screen 2 and then screen 2 to screen 1 using the modal option. This clearly works but when I debug an application built this way, it instantiates a new instance of each screen (view controller) for every segue performed. In the diagram below (apologies, I drew a nice picture but due to my newbie status, was not able to post it), how do I go from screen 1 to screen 2 to screen 3 and back to original screen 1 without creating a new instance? // Screen 1 --> Screen 2 --> Screen3 // ^ | // | | // +-------------------------+

  • Finding which files were "FIXED"and how many times between two specific date by using Trac?

    - by mkafkas
    I need to find out that how many times and which files are fixed or changed due to a bug between two specific dates in an open source project which uses Trac. I selected Webkit project for that purpose. (https://trac.webkit.org/) However, it can be any open source project. What can I do for that? How do I start? Do i have to use version control systems like svn or git for intergration? I am kinda newbie for these bug-tracking and issue-tracking systems.

  • Mono on OS X Compatible with MSVC 2010 peers?

    - by Chris
    I'm to begin .NET development at work but have the option of using MonoDevelop/Mono on OS X instead of MSVC 2010 on Windows and would prefer it because of my familiarity with OS X. We are likely going to use a number of popular frameworks, such as NHibernate and Castle DI - my question to those of you familiar with .NET development and Mono: will I be at much of a disadvantage? Are there strong incompatibilities or, with some "paper cuts", the two systems are roughly compatible? Again, my colleagues will be using MSVC 2010 and we intend on working on the same codebases together. Thanks for any insight you can give to this .NET newbie. EDIT: I should note I'll primarily be doing development with MVC 2, which I understand does work with Mono, and will have some leeward in choosing frameworks, i.e. I can avoid highly incompatible frameworks.

  • How can I access Android private API's which doesn't exposed in TelephonyManager?

    - by Micha Valach
    Hi, I'm newbie in Android. I intend to write tests related the Phone and Direct SIM write. What are the alternatives in case the required API's does not exposed in TelephonyManager but exist as private APIs in PhoneBase.java or PhoneFactory.java or CommandInterface.java? examples: 1. What is the "replacement" for: mPhone = PhoneFactory.getDefaultPhone(); ? 2. What is the alternative in order to access the CommandsInterface, CommandsInterface mCmdIf = ((PhoneBase)mPhone).mCM ? Thanks In Advance, Micha

  • Random numbers from binomial distribution

    - by Sarah
    I need to generate quickly lots of random numbers from binomial distributions for dramatically different trial sizes (most, however, will be small). I was hoping not to have to code an algorithm by hand (see, e.g., this related discussion from November), because I'm a novice programmer and don't like reinventing wheels. It appears Boost does not supply a generator for binomially distributed variates, but TR1 and GSL do. Is there a good reason to choose one over the other, or is it better that I write something customized to my situation? I don't know if this makes sense, but I'll alternate between generating numbers from uniform distributions and binomial distributions throughout the program, and I'd like for them to share the same seed and to minimize overhead. I'd love some advice or examples for what I should be considering.

  • In the generic programming/TMP world what exactly is a model / a policy and a "concept" ?

    - by Hassan Syed
    I'd like to know the precise yet succinct definitions of these three concepts in one place. The quality of the answer should depend on the following two points. Show a simple code snippet to show how and what the concept/technique is used for. Be simple enough to understand so that a programmer without any exposure to this area can grasp it. Note: There are probably many correct answers since each concept has many different facets. If there are a lot of good answers I will eventually turn the question into CW and aggregate the answers. -- Post Accept Edit -- Boost has a nice article on generic programming concepts

  • Which programming paradigm or language open most your mind?

    - by Dom De Felice
    It is often said that some programming languages exist that once grasped can open your mind and change the way you write software. A sort of "software design enlightenment", we can say. I heard this about Lisp, Smalltalk, Haskell, pure functional programming in general.. What are your experiences about this? I know that the right language to use depends on your needs, but I would like to know the one that better improve your programming skills in general. What do you think would be the best language/paradigm to learn to end up being a better programmer in the long run?

  • Retrieving content of a txt file from URL to Android

    - by eightx2
    I would like to be able to retrieve contents of a .txt file from the internet, and load it in an EditText. I tried using the code on this page: Reading Text File From Server on Android It didn't work, as you might have guessed. I've read on numerous sites about this type of problem, but I can't get anything to work. Someone suggested AndroidHttpClient (http://developer.android.com/reference/android/net/http/AndroidHttpClient.html), but I simply can't find any examples with this. As I'm a newbie in Android programming, I would love if someone could please give me a small example.

  • C# How to place a comma after each word but the last in the list

    - by user576712
    I totally new to C# and learning as I go. I am stuck on issue which I'm hoping an experienced programmer can help. I have added a CheckedListBox to my form and added a collection of 6 items to it. I need all but the last item selected to have a comma placed beside it, so my question is: how can I tell C# NOT to place a comma beside the last item selected? foreach (object itemChecked in RolesCheckedListBox.CheckedItems) { sw.Write(itemChecked.ToString() + ","); } Thanks for any help received!

  • Latitude & longitude coordinates of Australian states/territories for database using Google Maps

    - by RMW
    Hi, We have a database which has location-based search using Google Maps API. However searching by state or territory in Australia is problematic because Google Maps locates these at the centre of the states and most population centres in Australia are on the coast. We need to hand code in the latitudes and longitudes so that when someone searches for the state 'NSW', for example, the database returns relevant results. Does anyone know where to find a list of the coordinates for the boundaries of Australian states & territories to code into the database? This will save our busy programmer a lot of time. Thanks in advance.

  • C++ for games

    - by Bi
    Hi I am a relatively newbie in C++ and worked in the game industry for a few months. I am looking to get back to the industry and understand that one needs to be a very good C++ programmer (mainly bcos of how competitive it is to get into making games). I was wondering if there are really good websites online that would help with that. Basically I am looking for something that would help me MASTER C++ concepts as well as help me be a good coder through programming examples that I can code. Thanks Bi
