  • Droid's mediaserver dies on camera.takePicture()

    - by SirBoss
    On Motorola Droid, Firmware 2.1-update1, Kernel 2.9.29-omap1, Build # ESE81 When attempting to take a picture, mediaserver dies with a segmentation fault. I've tried putting takePicture in a timer and running it a few seconds after camera initialization to check for race conditions, but no change. Just calling Camera.open() doesn't cause the crash. Also, calling Camera.open() causes what I think is the autofocus motor to make a sort of ticking sound. Code that breaks: import android.app.Activity; import android.os.Bundle; public final class ChopperMain extends Activity { public void onCreate(Bundle savedInstanceState) { try { Camera camera = Camera.open(); catch (Exception e) { e.printStackTrace(); } camera.takePicture( new Camera.ShutterCallback() { public void onShutter() { ; } }, new Camera.PictureCallback() { public void onPictureTaken(byte[] data, Camera camera) { ; } }, new Camera.PictureCallback() { public void onPictureTaken(byte[] data, Camera camera) { ; } }, new PictureCallback() { public void onPictureTaken(byte[] data, Camera camera) { System.out.println("Ta da."); } } }); } catch (Exception e) { e.printStackTrace(); } } } Debug Log: D/CameraHal(10158): CameraSettings constructor D/CameraHal(10158): CameraHal constructor D/CameraHal(10158): Model ID: Droid D/CameraHal(10158): Software ID 2.1-update1 D/dalvikvm( 988): GC freed 2 objects / 56 bytes in 215ms D/ViewFlipper( 1074): updateRunning() mVisible=false, mStarted=true, mUserPresent=false, mRunning=false I/HPAndroidHAL(10158): Version 2988.

  • How Do I Setup the Notepad++ Run Command for Ruby?

    - by EstanislaoStan
    I'm trying to setup the Notepad++ IDE so that when I press F6 the Ruby script I'm editing will run. After searching the internet I've found that putting [cmd /K ruby "$(FULL_CURRENT_PATH)"] without the brackets into the run dialogue box that pops up when I press F5 will run basic scripts in the Command Prompt (I'm using Windows 7). However, if my code loads any external data such as .txt files, or as I've found with Gosu, loads any image files, Ruby complains that things do not exist which do in fact exist. I know my code and Ruby installation (Ruby 1.9.3) are fine because prior to now I've been using FreeRIDE, an older, somewhat buggy IDE that I've grown tired of, and my code runs fine when I press F5 using that IDE. Some examples of the complaints follow.

  • Setting Ubuntu Global PATH for Ruby Enterprise Edition

    - by Wally Glutton
    Context: I recently installed Ruby Enterprise Edition (REE) on an Ubuntu 8.04 server. I would like for this new version of Ruby to globally supersede (for all users, crontabs, etc) the older version in /usr/local/bin. Attempted Solution #1: The REE documentation recommends placing the REE bin folder at the beginning of the global PATH in /etc/environment. I altered the PATH line in this file to read: PATH="/opt/ruby_ee/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" This did affect my PATH at all. Attempted Solution #2: Next I followed these instructions and updated the PATH setting in the /etc/login.defs and /etc/crontab files. (I did not change /etc/sudoers.) This didn't affect my PATH either, even after logging out and rebooting the server. Other information: I seem to be having the same problem described here. I'm testing using the command: echo $PATH My shell is bash. My .bashrc doesn't not alter my PATH. I'm ssh'ed into the system for all testing. /opt/ruby_ee/ is a sym-link to /opt/ruby-enterprise-1.8.7-2011.03/

  • Ruby on Rails cannot find Initializer?

    - by Ryan M.
    Hello, I am trying to deploy an app to a fresh Ubuntu 10 installation using Passenger 2.2.15, Rails 2.3.5, Ruby 1.8.7, and Apache 2.2.14. However, even with a default rails app (sudo rails defaultapp), I am receiving the following error: "no such file to load -- initializer". I'm not sure which files you might need copies of in order to diagnose this problem, so I'll copy a few here and hope that it will help.

  • Visual studio debug console sometimes stays open and is impossible to close

    - by JC
    Hey, Sometimes when I run an application from Visual Studio and it crashes or I stop it using the stop button in the debug menu (Debug-Stop Debugging (Shift-F5)), the console of said application stays open... and never closes. I cannot close it by clicking the 'x' button in the top right corner. I cannot kill the process as it is not even listed in taskmgr. I have seen this problem documented in different places on the web, but no solution so far. I am running on windows XP SP3, using visual studio 2008 w/ SP1. 1- What could be causing this ? 2- Is there a fix ? thanks alot. JC EDIT: There is no MyApp.vshost.exe process to close, and closing visual studio does not close the console either. Worse even, if I try to restart my computer windows will hang and never close, I need to do a forced shut down. EDIT #2 : (from Brad Sullivan, Program Manager - Visual Studio Debugger on March 2nd) [...] this issue is likely not in Visual Studio since it also occurs in scenarios where Visual Studio is not present. We are in the process of handing over our investigation to the Windows Servicing team. But for now, removing the KB978037 update and it's related files seems to work.

  • Improve speed of own debug visualizer for Delphi 2010

    - by netcodecz
    I wrote Delphi debug visualizer for TDataSet to display values of current row, source + screenshot: http://delphi.netcode.cz/text/tdataset-debug-visualizer.aspx . Working good, but very slow. I did some optimalization (how to get fieldnames) but still for only 20 fields takes 10 seconds to show - very bad. Main problem seems to be slow IOTAThread90.Evaluate used by main code shown below, this procedure cost most of time, line with ** about 80% time. FExpression is name of TDataset in code. procedure TDataSetViewerFrame.mFillData; var iCount: Integer; I: Integer; // sw: TStopwatch; s: string; begin // sw := TStopwatch.StartNew; iCount := StrToIntDef(Evaluate(FExpression+'.Fields.Count'), 0); for I := 0 to iCount - 1 do begin s:= s + Format('%s.Fields[%d].FieldName+'',''+', [FExpression, I]); // FFields.Add(Evaluate(Format('%s.Fields[%d].FieldName', [FExpression, I]))); FValues.Add(Evaluate(Format('%s.Fields[%d].Value', [FExpression, I]))); //** end; if s<> '' then Delete(s, length(s)-4, 5); s := Evaluate(s); s:= Copy(s, 2, Length(s) -2); FFields.CommaText := s; { sw.Stop; s := sw.Elapsed; Application.MessageBox(Pchar(s), '');} end; Now I have no idea how to improve performance.

  • Temporary debug releases and final application releases

    - by baron
    I have a quick question regarding debug and release in VS 2008. I have an app i've been working on - its not yet complete but the bulk of the functionality is there. So basically i'm trying to give a copy of it now to the person helping with documentation - just so they can have a play and get the feel for what i've made. Now the question is how to provide it to them. I was told to just copy the .exe out of the debug/bin folder and put that onto USB. But when testing, if I run this .exe anywhere else (outside of this folder) it crashes. I've now worked out why this is: var path = ConfigurationManager.AppSettings["PathToUse"]; var files = Directory.GetFiles(path); throws a null reference, so that App.config file is not being used. If I copy that file in with the .exe it works again. So actually my question is regarding the best way to manage this situation. What is the best way to provide a working copy to people, and, is there a reference on preparing apps for release - so everything is packaged together and installed in a clean structured folder heirarchy?

  • Having trouble with confusing behaviour of error between debug and release modes in Xcode

    - by Cocorico
    Hi guys, I am confused over something (what is new!). I have an iPhone program I am writing and using some sqlite in a certain method, and there is some error which is giving me a message that says "Program received signal: “EXC_BAD_ACCESS” Okay, so I am trying to hunt down why this is doing this, and I notice something: When I run the program in debug mode, it gives me this error every single time I access this method (I test on the device). However when I run the program in release mode, I can access this method 2 times, and then it will give me this error the third time. So I mean, can someone just give me an explanation of what might cause this, I think that maybe deep-down I am not that smart on the difference in XCode of debug and release modes. I think that release mode does optimizing, and I guess the actual assembly machine code comes out different, yes? I AM A BIG NEWBIE USER UNFORTUNATELY! I am not clear on a lot of things like this, or whether it needs for I to remove nslog commands in the release build and such. Maybe I should just post the actual code in separate Stack OVerflow post, and see if people can see the error, then maybe this all become clear to me.

  • Using in the same time Boost in release and debug mode

    - by Oodini
    Hello, The title is just for teasing. :-) I know it isn't possible, but here is my problem. My app (a DLL, actually) uses Boost. It also uses an external API, which also uses Boost. The external API is of course provided in a release binary, anlong the needed release Boost binaries. When I compile/link my DLL in release mode, I have no problem. I precise I link my app to Boost in a dynamic way (BOOST_ALL_DYN_LINK). In debug mode, I can't load my DLL. I am not sure it is because of Boost, but I suspect Windows doesn't like working with two Boost (the release one called by the external lib, and the debug one called by my code). Will it work better if I link my code statically with the release Boost ? I don't think it is related to CRT, because I have nothing in the Events Viewer. I use Visual Studio 2005 SP1. Thanks.

  • Calling Perl and/or Python from Ruby

    - by Yktula
    Would it be possible to integrate Python (and/or Perl) and Ruby with some degree of transparency? I've looked at http://www.goto.info.waseda.ac.jp/~fukusima/ruby/python/doc/ and http://code.google.com/p/ruby-perl/ , but they both seem rather outdated. Perhaps this is not an appropriate approach, but would it be possible to generate a Ruby interface for Python's C API?

    I have a function in C++ that takes in an std::istream as the input: class Foo { Foo(std::istream &); } Using SWIG, I've bound it to Ruby, but Ruby's $stdin variable is fundamentally different from anything like the stream classes in C++, so I'm not sure how to either 1) expose the C++ class to Ruby in a way that I can use $stdin, or 2) convert $stdin into something the C++ class can understand. Anyone have experience with binding iostreams in C++ to Ruby? Thanks.

  • Installing Ruby 1.9.1 on Ubuntu?

    - by Björn
    I wonder about installing the latest version of Ruby on Ubuntu 9.04. Now I can run through the ./configure and make stuff fine, but what I wonder about: how to avoid conflicts with the packaging system? For example if some other package I install depends on Ruby, wouldn't the package manager install the (outdated) Ruby package and in the worst case overwrite my files? So I think I need some way to tell Ubuntu that Ruby is in fact already installed?

  • i = true and false in Ruby is true?

    - by alex
    Am I fundamentally misunderstanding Ruby here? I've been writing Ruby code for about 2 years now and just today stumbled on this... ruby-1.8.7-p249 > i = true and false => false ruby-1.8.7-p249 > i => true Could somebody explain what's going on here please? I'm sure it's to spec, but it just seems counter intuitive to me...

  • syntax difference between ruby and python?

    - by fayer
    i wonder if there are tutorials that go through the syntax differences for ruby and python? i have seen a comparison between ruby and php but not between ruby and python. i have looked at both ruby and python but it would be very useful with this side-by-side comparison for deciding which one to choose. thanks

  • current_user and Comments on Posts - Create another association or loop posts? - Ruby on Rails

    - by bgadoci
    I have created a blog application using Ruby on Rails and have just added an authentication piece and it is working nicely. I am now trying to go back through my application to adjust the code such that it only shows information that is associated with a certain user. Currently, Users has_many :posts and Posts has_many :comments. When a post is created I am successfully inserting the user_id into the post table. Additionally I am successfully only displaying the posts that belong to a certain user upon their login in the /views/posts/index.html.erb view. My problem is with the comments. For instance on the home page, when logged in, a user will see only posts that they have written, but comments from all users on all posts. Which is not what I want and need some direction in correcting. I want only to display the comments written on all of the logged in users posts. Do I need to create associations such that comments also belong to user? Or is there a way to adjust my code to simply loop through post to display this data. I have put the code for the PostsController, CommentsController, and /posts/index.html.erb below and also my view code but will post more if needed. class PostsController < ApplicationController before_filter :authenticate auto_complete_for :tag, :tag_name auto_complete_for :ugtag, :ugctag_name def index @tag_counts = Tag.count(:group => :tag_name, :order => 'count_all DESC', :limit => 20) conditions, joins = {}, :votes @ugtag_counts = Ugtag.count(:group => :ugctag_name, :order => 'count_all DESC', :limit => 20) conditions, joins = {}, :votes @vote_counts = Vote.count(:group => :post_title, :order => 'count_all DESC', :limit => 20) conditions, joins = {}, :votes unless(params[:tag_name] || "").empty? conditions = ["tags.tag_name = ?

  • Advanced Array Sorting in Ruby

    - by Ruby Beginner
    I'm currently working on a project in ruby, and I hit a wall on how I should proceed. In the project I'm using Dir.glob to search a directory and all of its subdirectories for certain file types and placing them into an arrays. The type of files I'm working with all have the same file name and are differentiated by their extensions. For example, txt_files = Dir.glob("**/*.txt") doc_files = Dir.glob("**/*.doc") rtf_files = Dir.glob("**/*.rtf") Would return something similar to, FILECON.txt ASSORTED.txt FIRST.txt FILECON.doc ASSORTED.doc FIRST.doc FILECON.rtf ASSORTED.rtf FIRST.rtf So, the question I have is how I could break down these arrays efficiently (dealing with thousands of files) and placing all files with the same filename into an array. The new array would look like, FILECON.txt FILECON.doc FILECON.rtf ASSORTED.txt ASSORTED.doc ASSORTED.rtf etc. etc. I'm not even sure if glob would be the correct way to do this (all the files with the same file name are in the same folders). Any help would be greatly appreciated!

  • mysql gem for snow leopard

    - by Will
    I had trouble with the gem at first but got it to work when I installed the 64-bit MySQL and reinsatlled the gem with arch flags. So it work in rails. The error I used to get was uninitialized constant MysqlCompat::MysqlRes but that is now gone :) However in Xcode when I run a RubyCocoa project I still get the old error of uninitialized constant MysqlCompat::MysqlRes Does anyone know why this may be? Is it because the gdb is 64-bit? How can it work in Rails but not in RubyCocoa? A little debugging shows that it fails to load mysql_api.bundle /Library/Ruby/Gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle: dlopen(/Library/Ruby/Gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle, 9): no suitable image found. Did find: (LoadError) /Library/Ruby/Gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle: mach-o, but wrong architecture - /Library/Ruby/Gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require'
