  • Artificial Intelligence Project - What language should I go for?

    - by Kremlin Yocepf
    Hi, I am a computer science student and I am going to work on an artificial intelligence project which will compose a musical tune according to the genre and mood inputs. Are the algorithms to be used for this project likely to be very resource-consuming? Would it make any difference (in terms of speed) if I choose to go with Java rather than C++? (Note : I know only these two languages and I am more comfortable with Java than C++.) NB : Sorry for my poor English. If someone can, please clean up this post wherever necessary. Thanks.

  • Environment.GetFolderPath(...CommonApplicationData) is still returning c:\Docs&Set on Vista

    - by blak3r
    As i understand it, you're supposed to use Environment.GetFolderPath method so you have OS independent code... WinXP uses C:\Docs and Settings\ Vista uses C:\ProgramData and c:\Users I'm using the code below on a vista computer and it's returning a c:\documents and settings directory instead of c:\ProgramData like it should... Any ideas? string commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData); try { File.CreateText( Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\\mycompany\\uid"); log.Debug("Created file successfully"); } catch (Exception ex) { log.Error("Unable to create the uid file: ", ex); } EDIT: I was mistaken... See my answer below. Please vote to close this post as it's no longer relevent.

  • Choose Your Own Adventure : BASIC Programming

    - by theraccoonbear
    Hopefully this isn't considered too off-topic, but I guess we'll see. I'd love to find and frame a copy of this book. Years ago, in my pre-teen years, I remember reading a lot of CYOA books, and one in particular stands out in my mind as the book that started me down the path of becoming a programmer. The details are fuzzy, but what I remember was that the story involved a programmer who was held captive somewhere and was trying to escape. IIRC, each section or chapter had a short BASIC program you could could type into your computer to simulate something from the story. The one that stands out most in my mind was a very simplistic animation made with pipes, pluses, and dashes that "looked" like a metal grate that opened (sliding upward). I realize this is pretty scant information to go on, but I suspect that anyone else who read the book would immediately remember it. Maybe not, I guess we'll see. Again, my apologies if this is too far off-topic for S.O.

  • Keeping iPhone App private after AppStore approval for beta testing.

    - by Stack
    I have messed around with AD-HOC distribution quite a bit and got it working too. The problem I am facing is all the people who I want to use as beta testers are "normal people" who never even sync their iPhone to iTunes on a computer. So, you can understand how technically challenged these people are, which is fine with me because that is the audience I want to use for testing. All these guys can do for me is if I can give them an AppStore link they will download it on their iPhone and test it for me. So, basically AD-HOC distribution (UDIDs, mobileprovision file and all that crap) is out of question for me. My Question is after AppStore approves my app, is there a way for me to be under the radar so that normal public can not download the app until I am ready. From past experience I know that the moment you put an app out there, in first week you get 100s of downloads and I dont want that to happen until my beta testing is finished.

  • Video/ Speech Development of Applications

    - by idea_
    Why do we continue to type and click away in IDEs when we could theoretically use hand gestures and speech to develop applications? Think about it - Developing a class by standing in-front of your computer, making some gesture, and yelling "CAR!". This doesn't have to strictly apply to OOP either. We have sufficient speech and image acquisition/ processing and analysis tools available to us, don't we? This seems plausible to me, but I may be overly ambitious. From a conceptual point-of-view, do you see any problems with the implementation?

  • More efficient way to write this Jquery code

    - by adamwstl
    Is there a better, more efficient way to write this code? It's a make shift drop down menu that allows user to RSVP for multiple people. Sorry, it's kind of a mess, but I think what I'm doing is clear. If not, I'm at my computer and will respond quickly with more info need be. //There's got to be a better way to do this $('#guest_num_1').click( function() { $('#num_guests a#quant_guests').html("1") $('.guest_name_2, .guest_name_3, .guest_name_4, .guest_name_5, .guest_name_6 ').hide() }); $('#guest_num_2').click( function() { $('#num_guests a#quant_guests').html("2") $('.guest_name_2').fadeIn() $('.guest_name_3, .guest_name_4, .guest_name_5, .guest_name_6').hide() }); $('#guest_num_3').click( function() { $('#num_guests a#quant_guests').html("3") $('.guest_name_2, .guest_name_3').fadeIn() $('.guest_name_4, .guest_name_5, .guest_name_6').hide() }); $('#guest_num_4').click( function() { $('#num_guests a#quant_guests').html("4") $('.guest_name_2, .guest_name_3, .guest_name_4').fadeIn() $('.guest_name_5, .guest_name_6').hide() }); $('#guest_num_5').click( function() { $('#num_guests a#quant_guests').html("5") $('.guest_name_2, .guest_name_3, .guest_name_4, .guest_name_5').fadeIn() $('.guest_name_6').hide() }); $('#guest_num_6').click( function() { $('#num_guests a#quant_guests').html("6") $('.guest_name_2, .guest_name_3, .guest_name_4, .guest_name_5, .guest_name_6').fadeIn() });

  • communicate with a process in utf-8 on a cp1252 consoless

    - by Mapad
    I need to control a program by sending commands in utf-8 encoding to its standard input. For this I run the program using subprocess.Popen(): proc = Popen("myexecutable.exe", shell=True, stdin=PIPE, stdout=PIPE, stderr=PIPE) proc.stdin.write(u'ééé'.encode('utf_8')) If I run this from a cygwin utf-8 console, it works. If I run it from a windows console (encoding ='cp1252') this doesn't work. Is there a way to make this work without having to install a cygwin utf-8 console on each computer I want it to run from ? (NB: I don't need to output anything to console)

  • iPhone App/Java Server Struct Data Issue over WiFi

    - by adimitri
    I currently have an iPhone app that communicates with a C++ server running on a computer, over WiFi. This app is sending its data (x,y coordinates) in a c-struct to the server. For further development, we would like the iPhone application to communicate directly with a java server, however the major issue is that java does not have the ability to emulate or use a c-struct. What would be the best way to send data (x,y coordinates) between the two devices? I can already establish a connection between the two devices. More specifically how I would receive the data and process it on the Java end. Thanks for your help, Alex

  • How do i use SQL Server 2008? With Visual Studios?

    - by acidzombie24
    Its a two part question. How do i use SQL Server 2008? With Visual Studios? I started up a dummy project and with server explorer i tried with create new sql server database and add connection using my computer name (it came from a dropdown) as the server location. When i tried to create the database 'TestDB1' i got an error. I dont understand why. Its a fresh install and i have restarted the comp a few times since then. I havent messed with visual studios or the servers or even the control options to disable anything that would have been automatic. So whats with this? -edit- My goals are 1) create a database. 2) Be able to see all the database that exist on the server 3) execute sql queries in the ide 4) be able to browse tables. I dont need all of these but as many possible would be nice.

  • HWID locking a PHP page?

    - by Rob
    Currently I sell a program, that accesses my webpage. The program is HWID (Hard Ware ID) locked, and the only reason I use the program to access the webpage instead of direct access via a webbrowser, is so that I can use HWID authentication. However, I've just been told I can code a script to get computer information, such as hardware ID etc. Is this actually possible completely server-side? If so, can I do it with PHP? If not, what language would this be, and what functions would I have to look into for this?

  • How to make shell output redirect (>) write while script is still running?

    - by Noio
    I wrote a short script that never terminates. This script continuously generates output that I have to check on every now and then. I'm running it on a lab computer through SSH, and redirecting the output to a file in my public_html folder on that machine. python script.py > ~/public_html/results.txt However, the results don't show up immediately when I refresh the address. The results show up when I terminate the program, but as I said, it doesn't halt by itself. Is that redirect (>) being lazy with with writing? Is there a way to continuously (or with an interval) update the results in the file? Or is it the webserver that doesn't update the file while it is still being written?

  • What are some good practice assignments for learning Java?

    - by HW
    Hello, I am a computer science in my Student Second year. I already know a good deal about C++, Data Structures, File Structures, OOP, etc. I decided to learn Java. I have read couple of books but I know that it takes practice to master any Programming language. I was wondering if anyone knew of some assignments or problems that helped them become good at programming. I am looking for something more challenging than "hello world"s and "3+2=5"s exercises. Thanks, ~HW

  • Detecting when Javascript is performing poorly

    - by what-the-crap
    I'm working on a webapp in jquery that, on older machines or machines without much resources, may perform poorly. To get around this I'd like to make a degraded version that disables some of the features, particularly those that rely on large images. How can I tell if my app is running poorly on the user's computer in jquery or javascript in general? I just need a way to call a function that will degrade the app. (especially when the user may run low on system memory) The only way I can think of is for manual user intervention, but the option would add clutter for users that don't need it and users that do need it may not notice it. Thanks!

  • headfile conflict let every line becomes "not declared"

    - by altria
    I have a.h a.cpp b.h and a library for b. The thing is, if I choose to include b.h in either a.h or a.cpp, it will let complier return "was not declared in this scope" for every line of a.h. The same program works fine on another computer, although Makefile might be different. I have to admit, I think I may have change some settings, but I forgot which one I changed. Is there anybody have any idea? I am using linux and gcc.

  • Setting language/culture for reporting services report rendered through C#

    - by Chris Latta
    I have written a report renderer in C# that runs and attaches reports to an email. This is all working great, except the date format of the parameters are incorrect when listed in the report title. All the reports have their language set to =User!Language and the parameters are output using the FormatDateTime function to format according to the user's regional settings. I am basically using the rendering method described here on MSDN. This all works great when the reports are run through the browser. However, when I render the report from C# it uses en-US date format. The report server's regional settings are set appropriately to the correct region as are the regional settings of the computer the C# progam is running on.. What property do I need to set in my C# program for the report to be rendered using my appropriate language/culture?

  • Is it faster to count down that it is to count up?

    - by Bob
    Our computer science teacher once said that for some reason it is more efficient to count down that count up. For example if you need to use a FOR loop and the loop index is not used somewhere (like printing a line of N * to the screen) I mean that code like this : for (i=N; i>=0; i--) putchar('*'); is better than: for (i=0; i<N; i++) putchar('*'); Is it really true? and if so does anyone know why?

  • How to automatically install an app on your iphone?

    - by wdlax11
    I'm looking to find a way to install an app automatically on an iphone. An example would be: I have an app called my.app. It's located on my desktop on my mac. When I plug in my iphone to my computer it automatically installs my.app on to my iphone. Is this possible? Any ideas of how I could possible do this or get a workaround? Or, it needs to prompt the user to install it. The app doesn't need to automatically install; it just needs to automatically prompt the user on the iPhone to ask if they want to install it or not.

  • How to learn programming language (syntax rules, etc.) and remember easily? [closed]

    - by user239522
    I'm new to programming, and I always have a so call difficulty, that is, I always tend to forget the thing (syntax, rules, name, definition or anyting) of a programming language I've learnt. And I personally do feel that the way I learn it is wrong. Here is my method. Everyday I will spend approximately 1 or 2 hours on a programming e-book. I just follow the syllabus and teaching inside the books, of course I have try to code myself, alter the code inside the book, and did the exercises available. But everytime right after I finish a chapter and advanced myself to third or fourth chapter, I will forgot something I learnt in the first chapter. Is it the method I use wrong? Does learning through reading and coding not enough? Do I need to everytime make a small note (mind map for example) of things I've learnt by hand writing? Or do I sometime need to try coding using a pencil and a book, but not a computer?

  • SQLite delete the last 25% of records in a database.

    - by Steven smethurst
    I am using a SQLite database to store values from a data logger. The data logger will eventually fills up all the available hard drive space on the computer. I'm looking for a way to remove the last 25% of the logs from the database once it reaches a certain limit. Using the following code: $ret = Query( 'SELECT id as last FROM data ORDER BY id desc LIMIT 1 ;' ); $last_id = $ret[0]['last'] ; $ret = Query( 'SELECT count( * ) as total FROM data' ); $start_id = $last_id - $ret[0]['total'] * 0.75 ; Query( 'DELETE FROM data WHERE id < '. round( $start_id, 0 ) ); A journal file gets created next to the database that fills up the remaining space on the drive until the script fails. How/Can I stop this journal file from being created? Anyway to combined all three SQL queries in to one statement?
