• Is my way of doing threads in Android correct?

  - by Charlie

  Hi, I'm writing a live wallpaper, and I'm forking off two separate threads in my main wallpaper service. One updates, and the other draws. I was under the impression that once you call thread.start(), it took care of everything for you, but after some trial and error, it seems that if I want my update and draw threads to keep running, I have to manually keep calling their run() methods? In other words, instead of calling start() on both threads and forgetting, I have to manually set up a delayed handler event that calls thread.run() on both the update and draw threads every 16 milliseconds. Is this the correct way of having a long running thread? Also, to kill threads, I'm just setting them to be daemons, then nulling them out. Is this method ok? Most examples I see use some sort of join() / interrupt() in a while loop...I don't understand that one...

• Extract domain from url (including the hard ones)

  - by karl

  I'm trying to write (or just find an existing) PHP method that can take a link and extract the url. The trick is, it needs to hold under the weight of strange looking domains like: www.champa.kku.ac.th Looking at this one myself with human eyes, I still guessed it incorrectly: thought the domain would be kku.ac.th but that gives a dns error when visiting. So anyone knows of a good way to reliably extract the domain from url: http://site.com/hello.php http://site.com.uk/hello.php http://subdomain.site.com/hello.php http://subdomain.site.com.uk/hello.php http://www.champa.kku.ac.th/hello.php // and even the one I couldn't tell

• How do you render a rails partial that is outside of a namespace in a view that is inside of a namespace?

  - by iand675

  I've got a 'static' controller and static views that are pages that don't utilize ruby in their views. For these pages, I have a sitemap partial that is generated programatically and used in the application layout file. Namespaced routes still use the application layout file but are taking the static routes and trying to namespace them too. Here's the relevant portion of the route file: namespace :admin do resources :verse_categories resources :verses resources :songs resources :flowers resources :visits, :except => [:new, :create] end match ':action' => 'static' root :to => 'static#home' Here's the error I'm getting: No route matches {:controller=>"admin/static", :action=>"about"} Note that about is one of the static pages that the sitemap partial uses. So, how can I resolve this routing issue so that it's not trying to find my static sites inside of the admin namespace? Any help would be appreciated!

• callin' c from lua crashes while reallocating

  - by mkind

  hi folks, i got a crazy error within that for-loop matr=realloc(matr, newmax*sizeof(matr*)); for (i=0; i<newmax; i++){ matr[i]=realloc(matr[i], newmax*sizeof(int)); } matr is a multi-dimension array: int **matr. i need to resize column and row. first line resizes column and the for-loop resizes every row. it worked fine in c. now im working on a library for lua and it crashs here. compilin' works fine as well. but calling from lua crashs with lua: malloc.c:3552: mremap_chunk: Assertion `((size + offset) & (mp_.pagesize-1)) == 0' failed. i have no damn idea since it's working fine using it in c.

• How to refresh database data only in SQL Server

  - by MaxGeek

  So I want to copy just the data from a Prod database (SQL 2005) down to my local machine (SQL 2005 & SQL 2008 Management Studio installed). The problem is I'm running into foreign key constraints that are causing the task/scripts to fail. I can get by these errors if I import certain tables first, but is there an easier way to do this all at once? I'm not a DBA so I don't have access to the database back up. I've tried the SQL Import/Export data Wizard and Publishing Wizard, but it also gets the PK error.

• FileNotFoundException when using FileInputStream

  - by user1672817

  I am trying to access a file I have contained in the jar. The beginning of my code is as follows: import java.io.*; import java.net.*; public class intro { public static void main(String[] args) throws IOException{ URL jarUrl = intro.class.getResource("myFile.jar"); File myJar = new File(jarUrl.toString()); FileInputStream fis = new FileInputStream(myjar); } I'm getting the following error: Exception in thread "main" java.io.FileNotFoundException: file:\...myFile.jar (The filename, directory name, or volume label syntax is incorrect) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(Unknown Source) at intro.main(intro.java:10) It seems to have no problem finding the URL or initializing the file, but I can't get the FileInputStream to work. Does anybody know what I'm doing wrong? Help would be appreciated.

• gprof and execl() - is it possible?

  - by Chris

  Background: I have a game (an old-school-esque MUD) which I've been attempting to profile with gprof. The documentation of gprof (on Linux 2.6) states that The profiled program must call "exit"(2) or return normally for the profiling information to be saved in the gmon.out file. Now, if I kill the server with the shutdown command, the application "returns normally" (i.e., main() returns) and I get a gmon.out to analyze. However, it's far more common to reboot the server. The reboot command does the following: Writes usernames and socket FD numbers to disc. Makes a call to execl(). The new process looks for the stored data, picks up the FDs, and moves on. I see the following error on the command line, as the whole process fails: Profiling timer expired ./program Question: Is it possible to get a gmon.out file from the execl()-calling process? Perhaps some environmental parameter to execl(), or else perhaps a different, gprof-friendly, system call to achieve the same effect (beginning a new process while preserving file descriptors)?

• How do I use the Zend Youtube API correctly?

  - by pharma_joe

  I am trying to access the YouTube API with the Zend libraries that I have included like this (the full path to the Zend library is components/lib/Zend/Gdata.php): //Include Zend Gdata set_include_path('components/lib'); include("Zend/Gdata.php"); I now try to use the framework thus: //Access video data via Zend library $yt = new Zend_Gdata_YouTube(); However when running the script it returns: Fatal error: Class 'Zend_Gdata_YouTube' not found in E:\inetpub\students\fit3060\20712510\ass2\results.php on line 48 I think I have not included the Zend library properly or declared the include path correctly?

• Reading Matrices in MATLAB and assigning coordinates to the entries

  - by Michael Schofield

  Hi, I'm a bit new to MATLAB. Basically, I have a 25x25 Matrix, complete with various random entries ranging from 0 to 3. I need to write a program that reads this matrix, and assigns x-y coordinates to the entries, so that when I ask for an input of a particular x-y coordinate which has, say an entry of 3, then it will result in an error. I'm a bit overwhelmed - but I understand the general concept of what I'm supposed to be finding. I'm wondering if I should use a plot instead to help me.

• Why won't Heroku accept my Gemfile.lock in Windows?

  - by mranders

  I have a rails application that I deploy on Heroku. I'm using several different machines, and I noticed that when I add new dependencies (so that Gemfile.lock is rebuilt) and do bundle install on my Windows computer at home, push to Heroku fails with the following error: Unresolved dependencies detected; Installing... Windows Gemfile.lock detected, ignoring it. You have modified your Gemfile in development but did not check the resulting snapshot (Gemfile.lock) into version control ... Gemfile.lock IS under version control, but Heroku appearently chooses to ignore it since it's created in Windows, and then complains that it's missing seconds later. Why does this happen? And how can I solve it?

• Fortran - String with unknown characters into substrings

  - by Masoud

  I am trying to put an input string into sub-string arrays. The number of data in the input file are less than 10 but unknown. The number of spaces between each data is also unclear. Example: Asd B Cwqe21 Ddsw Eww I am quite novice to Fortran, so I do not know which format I should use. My problem is that I do not know the number of data (here I assumed that there are 5), so how can I make the code work? I tried the following which did not work: CHARACTER (LEN=100), DIMENSION(10) :: string READ (1,*) (string,I=1,10) It seems that the error I got was because there was no 6th string to read and put into string(6). I tried using the "Index" to find the space, but since I do not know how many spaces are in the string, it did not help me.

• Send data to server with GET

  - by coderjoe

  I have made a site where all my highscores from my game are shown. I send the scores from my iphone game to my site using a script made with php. The script works, because if I enter the link produced by my app in my browser the score is added. However I want to send the scores from my app. The script is using the GET method to get name, scores etcetera. This is what i have now: NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]]; NSError * e; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&e]; But it's not sending data to my server. The urlString is correct, because if I enter the link produced by my app in my browser the score is added. How can i solve this problem, Thanks in advance

• Rails: Creating subfolders in model?

  - by keruilin

  I'm going to have a ton of subclasses, so want to organize them under a subfolder called stream. I added the following line to the environment.rb so that all classes in the subfolder would be loaded: Rails::Initializer.run do |config| ... config.load_paths += Dir["#{RAILS_ROOT}/app/models/*"].find_all { |f| File.stat(f).directory? } ... end I thought this would solve the issue in which by convention the model class is namespaced into an according module. However, when I try to call one of the classes called stream in the stream folder, I get the following error: NoMethodError: undefined method `new' for Stream:Module from (irb):28 from /usr/local/bin/irb:12:in `<main>' Here's the model for the parent and one child: class Stream end class EventStream < Stream end Any idea what the issue is?

• How to check the compatibility between my program and the .net framework versions?

  - by Jack

  Hi all I am writing a program which is targeted to run on .net framework 2.0. I have chosen 2.0 in my VS project. It runs fine on my machine (mine has 2.0 SP2), so there is no compile error. but when I tried to run it on another machine (only with 2.0, no sp), it cannot run. I am aware that I used some method which is supported by 2.0 but only with 2.0 SP2. .net framework 2.0 SP2 seems not being listed in VS IDE, that's why VS cannot give me any warning when I compiled it on my machine. How can I easily check the compatibility of my codes with .net framework 2.0 SP2? or I just have to look at msdn to check every method I have used??? thanks

• Good way to fetch XML from a remote URL, convert it to HTML and display it in a ASP.NET-page

  - by Binary255

  Hi, The use case I want to achive is. 1. Fetch XML from a remote URL. 2. Convert it to HTML using XSLT 3. Insert the generated HTML at a position in my ASP.NET web forms page. Alternative on the above, if 1 returns a 404: 2. Generate HTML which display an error message to the user. Only step 3 is left as I've completed 1-2. As there are logic for handling the two execution paths and performing the XSLT-transformation I thought it would be suitable to keep it in the code-behind file. What's a good, clean way of inserting generated HTML at a position in my ASP.NET web forms page?

• C++ allocate objects on heap of base class with protected constructors via inheritance

  - by KRao

  I have a class with protected constructor: class B { protected: B(){}; }; Now I derive from it and define two static functions and I manage to actually create objects of the class B, but not on the heap: class A : public B { public: static B createOnStack() {return B();} //static B* createOnHeap() {return new B;} //Compile time Error on VS2010 }; B b = A::createOnStack(); //This works on VS2010! The question is: 1) Is VS2010 wrong in allowing the first case? 2) Is it possible to create objects of B without modifying B in any way (no friendship and no extra functions). I am asking, because it is possible to make something similar when dealing with instances of B and its member functions, see: http://accu.org/index.php/journals/296 Thank you in advance for any suggestion! Kind regards

• Help Fix a bug - Unexpected T_STRING

  - by thecoshman

  So I have just rebuilt my server, just on local network. Stick my site back on it, try to run the code, and I get a anice T_STRING error. This is all very strange, as I have not changed the code :S <?php $window_ID = -1; if(isset($_POST["window_ID"]) AND $_POST["window_ID"] != null){ $window_ID = trim($_POST["window_ID"]); } ?> This is the start of the file, apter this rather loverly snipit of PHP the rest is just XMl, yet on line 6 appertnlty there is an unexpected T_STRING, which is strange considering all that is on that line is the ?>, then the XML starts up... Any one got any ideas what has gone wrong here? Any chance it ould be magic quotes? I had turned it of before, but I want to now update my code to check for the magic quotes and avoid its stupid actions.
