  • ERROR: Failed to build gem native extension on Mavericks

    - by Kyle Decot
    I'm attempting to run bundle in my Rails project on OSX 10.9.

  • Channel Audio from .mp4?

    - by Kyle
    Hi there. I am at a loss here after searching around with no results. I am attempting to channel the audio specifically from an .mp4 for use in a driver. I am aware that there are programs which extract the audio from .mp4's, but I am looking for another approach without using external applications such as those.. is there any direction that someone can point me towards to solve this problem? Thanks, -K

  • GOTO still considered harmful?

    - by Kyle Cronin
    Everyone is aware of Dijkstra's Letters to the editor: go to statement considered harmful (also here .html transcript and here .pdf) and there has been a formidable push since that time to eschew the goto statement whenever possible. While it's possible to use goto to produce unmaintainable, sprawling code, it nevertheless remains in modern programming languages. Even the advanced continuation control structure in Scheme can be described as a sophisticated goto. What circumstances warrant the use of goto? When is it best to avoid? As a followup question: C provides a pair of functions, setjmp and longjmp, that provide the ability to goto not just within the current stack frame but within any of the calling frames. Should these be considered as dangerous as goto? More dangerous? Dijkstra himself regretted that title, of which he was not responsible for. At the end of EWD1308 (also here .pdf) he wrote: Finally a short story for the record. In 1968, the Communications of the ACM published a text of mine under the title "The goto statement considered harmful", which in later years would be most frequently referenced, regrettably, however, often by authors who had seen no more of it than its title, which became a cornerstone of my fame by becoming a template: we would see all sorts of articles under the title "X considered harmful" for almost any X, including one titled "Dijkstra considered harmful". But what had happened? I had submitted a paper under the title "A case against the goto statement", which, in order to speed up its publication, the editor had changed into a "letter to the Editor", and in the process he had given it a new title of his own invention! The editor was Niklaus Wirth. A well thought out classic paper about this topic, to be matched to that of Dijkstra, is Structured Programming with go to Statements (also here .pdf), by Donald E. Knuth. Reading both helps to reestablish context and a non-dogmatic understanding of the subject. In this paper, Dijkstra's opinion on this case is reported and is even more strong: Donald E. Knuth: I believe that by presenting such a view I am not in fact disagreeing sharply with Dijkstra's ideas, since he recently wrote the following: "Please don't fall into the trap of believing that I am terribly dogmatical about [the go to statement]. I have the uncomfortable feeling that others are making a religion out of it, as if the conceptual problems of programming could be solved by a single trick, by a simple form of coding discipline!"

  • IE positioning problems

    - by Kyle Sevenoaks
    In every browser but IE, on euroworker.no/order the little green arrow under the word "produkt" sits on top of my div container. Why in the world does this not work in IE? Thing is, it works on two pages out of four in IE but all four in other browsers.

  • How do I add a condition to all ActiveRecords Queries for a particular model?

    - by Kyle West
    I am using the sentient_user gem to have access to the current_user object in my application. I want to override the default ActiveRecordBase queries to scope them to the current user. For instance, I don't want my users looking at, deleting, modifying other user's orders. I feel like I should be able to override a single (or couple) ActiveRecordBase methods to accomplish this, but I don't know which or how. Thanks in advance.

  • How do you set Android ViewPager to encompass only one View or Layout?

    - by Kyle
    I am struggling with the concepts needed to properly implement a view pager. By following some tutorials and referencing developer.android.com, I am able to get a view pager almost fully functional. The pager will flip through several text views that have been setup to say "My Message 0" through "My Message 9". The problem is that the view pager also flips the button on the bottom of the activity and the red block that is right above the button. I would like to have the view pager only cycle through the text. Would you please help me understand what I'm doing wrong? I have an activity that represents a dashboard: public class DashBoard extends FragmentActivity { private static final int NUMBER_OF_PAGES = 10; private ViewPager mViewPager; private MyFragmentPagerAdapter mMyFragmentPagerAdapter; public void onCreate(Bundle icicle){ super.onCreate(icicle); setContentView(R.layout.dashboard); mViewPager = (ViewPager) findViewById(R.id.viewpager); mMyFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager()); mViewPager.setAdapter(mMyFragmentPagerAdapter); } private static class MyFragmentPagerAdapter extends FragmentPagerAdapter{ public MyFragmentPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int index) { return PageFragment.newInstance("My Message " + index); } @Override public int getCount(){ return NUMBER_OF_PAGES; } } and a class for the page fragment: public class PageFragment extends Fragment { public static PageFragment newInstance(String title){ PageFragment pageFragment = new PageFragment(); Bundle bundle = new Bundle(); bundle.putString("title", title); pageFragment.setArguments(bundle); return pageFragment; } @Override public void onCreate(Bundle icicle){ super.onCreate(icicle); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle icicle){ View view = inflater.inflate(R.layout.dashboard, container, false); TextView textView = (TextView) view.findViewById(R.id.textViewPage); textView.setText(getArguments().getString("title")); return view; } } and finally, my xml for the dashboard: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/dashbaordLabel" android:layout_width="match_parent" android:layout_height="wrap_content" > <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" /> <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> <Button android:id="@+id/newGoalButton" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/stringNewGoal" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:onClick="createNewGoal" /> <RelativeLayout android:id="@+id/SpaceBottom" android:layout_width="match_parent" android:layout_height="75dp" android:layout_above="@id/newGoalButton" android:background="@color/red" > </RelativeLayout> </RelativeLayout> A note about my xml, I tried wrapping the text view in some view pager tags eg: <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" > <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> </android.support.v4.view.ViewPager> But all that did was make the text view disappear from the screen, while the button and red block still cycled as in the original issue.

  • Can't find how to import as one object or how to merge

    - by Aaron
    I need write a script in blender that creates some birds which fly around some obstacles. The problem is that I need to import a pretty large Collada model (a building) which consists of multiple objects. The import works fine, but the the building is not seen as 1 object. I need to resize and move this building, but I can only get the last object in the building (which is a camera)... Does anyone know how to merge this building in 1 object, group, variable... so I can resize and move it correctly? Part of the code I used: bpy.ops.wm.collada_import(filepath="C:\\Users\\me\\building.dae") building= bpy.context.object building.scale = (100, 100, 100) building.name = "building"

  • Faster Matrix Multiplication in C#

    - by Kyle Lahnakoski
    I have as small c# project that involves matrices. I am processing large amounts of data by splitting it into n-length chunks, treating the chucks as vectors, and multiplying by a Vandermonde** matrix. The problem is, depending on the conditions, the size of the chucks and corresponding Vandermonde** matrix can vary. I have a general solution which is easy to read, but way too slow: public byte[] addBlockRedundancy(byte[] data) { if (data.Length!=numGood) D.error("Expecting data to be just "+numGood+" bytes long"); aMatrix d=aMatrix.newColumnMatrix(this.mod, data); var r=vandermonde.multiplyBy(d); return r.ToByteArray(); }//method This can process about 1/4 megabytes per second on my i5 U470 @ 1.33GHz. I can make this faster by manually inlining the matrix multiplication: int o=0; int d=0; for (d=0; d<data.Length-numGood; d+=numGood) { for (int r=0; r<numGood+numRedundant; r++) { Byte value=0; for (int c=0; c<numGood; c++) { value=mod.Add(value, mod.Multiply(vandermonde.get(r, c), data[d+c])); }//for output[r][o]=value; }//for o++; }//for This can process about 1 meg a second. (Please note the "mod" is performing operations over GF(2^8) modulo my favorite irreducible polynomial.) I know this can get a lot faster: After all, the Vandermonde** matrix is mostly zeros. I should be able to make a routine, or find a routine, that can take my matrix and return a optimized method which will effectively multiply vectors by the given matrix, but faster. Then, when I give this routine a 5x5 Vandermonde matrix (the identity matrix), there is simply no arithmetic to perform, and the original data is just copied. ** Please note: What I use the term "Vandermonde", I actually mean an Identity matrix with some number of rows from the Vandermonde matrix appended (see comments). This matrix is wonderful because of all the zeros, and because if you remove enough rows (of your choosing) to make it square, it is an invertible matrix. And, of course, I would like to use this same routine to convert any one of those inverted matrices into an optimized series of instructions. How can I make this matrix multiplication faster? Thanks! (edited to correct my mistake with Vandermonde matrix)

  • Android NDK Question

    - by Kyle
    The NDK does not contain very many shared libraries for you to access. As a result, I must build many sources myself and link them into my shared library via static/shared libraries. I want to compile libpng as a Static Library. Trouble is, I have absolutely no idea how, nor does google instruct you how to do so in their NDK. I'm no expert on the NDK even after reading everything I can find, so I would really appreciate someone who actually knows how this is done. I do have the Android.mk file for libpng, as google's Android OS source contains it. Infact, I got the entire directory on the android OS source for libpng and it's dependent libraries. It was somewhat of a shortcut instead of making one myself. I don't know how to make a particular directory which contains this file, though. Thanks for reading!

  • Does NSArray:lastObject return an autoreleased object?

    - by Kyle
    I'm working on an iPhone project where I would like to retrieve an object from an NSMutableArray, remove the object from the array and then use it later. The code looks something like this: NSMutableArray * array; // fill the array NSObject * obj = [array lastObject]; [array removeLastObject]; // do something with obj (in the same function) array is the only entity with a retain on the object that is being accessed. Is this safe to do? I would assume that this would only work if lastObject autoreleased the object which is something that I can't figure out if it does.

  • 2D Ball Collisions with Corners

    - by Aaron
    I'm trying to write a 2D simulation of a ball that bounces off of fixed vertical and horizontal walls. Simulating collisions with the faces of the walls was pretty simple--just negate the X-velocity for a vertical wall or the Y-velocity for a horizontal wall. The problem is that the ball can also collide with the corners of the walls, where a horizontal wall meets with a vertical wall. I have already figured out how to detect when a collision with a corner is occurring. My question is how the ball should react to this collision--that is, how its X and Y velocities will change as a result. Here's a list of what I already know or know how to find: *The X and Y coordinates of the ball's center during the frame when a collision is detected *The X and Y components of the ball's velocity *The X and Y coordinates of the corner *The angle between the ball's center and the corner *The angle in which the ball is traveling just before the collision *The amount that the ball is overlapping the corner when the collision is detected I'm guessing that it's best to pretend that the corner is an infinitely small circle, so I can treat a collision between the ball and that circle as if the ball were colliding with a wall that runs tangent to the circles at the point of collision. It seems to me that all I need to do is rotate the coordinate system to line up with this imaginary wall, reverse the X component of the ball's velocity under this system, and rotate the coordinates back to the original system. The problem is that I have no idea how to program this. By the way, this is an ideal simulation. I'm not taking anything like friction or the ball's rotation into account. I'm using Objective-C, but I'd really just like a general algorithm or some advice. Many thanks if anyone can help!

  • Create a thumbnail of a dwg in in a linux environment

    - by Kyle
    Creating a ruby on rails site that uses RMagick to create thumbnails for many types of images. RMagick cannot read dwg files however. I've tried a few things, looked into the Java library JDWGLib, which would probably allow me to write a converter, but it would be a total from the ground up solution, where I just need a thumbnail. Also considered using a viewer program to open the file in a remote X session and do a screen capture, however I'm not sure how I could ever guarantee that the viewer had completed opening when I took the screenshot. I'm not concerned with being able to manipulate the file other than to create the thumbnail. It is going to be used for commercial purposes, so any libraries used need to be compatible.

  • Retrieving Absolute URL from File on Mounted Volume in Cocoa

    - by Bryan Kyle
    Is there any way of retrieving an absolute URL for a file on a mounted volume in Cocoa? For example, say afp://server/Documents is mounted at /Volumes/Documents. How can I get full URL to a file on the mounted volume in the form of afp://server/Documents/path/to/file? I've tried using statfs but the value of f_mntfromname doesn't contain a url, it contains the same value that is given by the mount command.

  • Does the Microsoft SQL Server native client support IDBAsynchNotify?

    - by Aaron Klotz
    I'm working on some OLE DB code that runs queries on MS SQL Server via ICommand::Execute. I'm converting this code to operate asynchronously by setting the DBPROPVAL_ASYNCH_INITIALIZE property on the command before executing. I'd prefer to register a IDBAsynchNotify sink so that my code can be notified of events, as opposed to polling or blocking via ISSAsynchStatus. The documentation for ICommand::Execute does not show IConnectionPointContainer as an acceptable riid parameter, but the same document, when discussing the DB_S_ASYNCHRONOUS return code, suggests that it is possible to request an IConnectionPointContainer interface that I could use to register my event sink. When I call ICommand::Execute, passing IID_IConnectionPointContainer as the riid parameter, I receive the E_NOINTERFACE error. I also tried setting the DBPROP_IConnectionPointContainer property before Execute but I received the same results. If I have to, I'll use ISSAsynchStatus, but I'd much rather use IDBAsynchNotify. Is it possible?

  • Android Custom Dialog NullPointerException

    - by Kyle Hughes
    I cannot for the life of me figure out why I'm getting a NullPointerException. When a user clicks on a particular image, a dialog window is supposed to pop-up and display a larger version of said image: private OnClickListener coverListener = new OnClickListener() { public void onClick(View v) { showDialog(DIALOG_COVER); } }; DIALOG_COVER is set to = 0. The associated onCreateDialog looks like this: protected Dialog onCreateDialog(int id) { Dialog dialog; switch(id) { case DIALOG_COVER: dialog = new Dialog(mContext); dialog.setContentView(R.layout.cover_dialog); dialog.setTitle(book.getTitle()); ImageView coverLarge = (ImageView)findViewById(R.id.coverLarge); coverLarge.setImageBitmap(book.getCover()); break; default: dialog = null; } return dialog; } For reference, this is cover_dialog.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/coverDialog" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp"> <ImageView android:id="@+id/coverLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="fitStart" /></LinearLayout> Now, when the image previously described is clicked, the application immediately crashes and throws the following error through LogCat: 06-08 13:29:17.727: ERROR/AndroidRuntime(2220): Uncaught handler: thread main exiting due to uncaught exception 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): java.lang.NullPointerException 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): at org.kylehughes.android.brarian.AndroidBrarian.onCreateDialog(AndroidBrarian.java:259) The line in question refers to this line inside of onCreateDialog: coverLarge.setImageBitmap(book.getCover()); Basically, I don't get why coverLarge is null at that point.

  • Fuzzy Search on Material Descriptions including numerical sizes & general descriptions of material t

    - by Kyle
    We're looking to provide a fuzzy search on an electrical materials database (i.e. conduit, cable, etc.). The problem is that, because of a lack of consistency across all material types, we could not split sizes into separate fields from the text description because some materials are rated by things other than size. I've attempted a combination of a full text search & a SQL CLR implementation of the Levenshtein search algorithm (for assistance in ranking), but my results are a little funky (i.e. they are not sorting correctly due to improper ranking). For example, if the search term is "3/4" ABCD Conduit", I'll might get back several irrelevant results in the following order: 1/2" Conduit 1/4" X 3/4" Cable 1/4" Cable Ties 3/4" DFC Conduit Tees 3/4" ABCD Conduit 3/4" Conduit I believe I've nailed the problem down to the fact that these two search algorithms do not factor in the relevance of punctuation & numeric. That is, in such a search, I'd expect the size to take precedence over any fuzzy match on the rest of the description, but my results don't reflect that. My question is: Can anyone recommend better search algorithms or different approaches that may be better suited for searching a combination of alphanumerics & punctuation characters?

  • Edit Html.ActionLink output string

Sure, it works but it seems like a hack. Is there a better way to accomplish this?

  • iPhone OpenGL Splash Screen? How?

    - by Kyle
    My app is based pretty much on the EAGLView in the SDK. It doesn't incorporate a ViewController. Rather it simply inits GL and starts painting immediately.. Currently, my app will load a very small PNG and displays it as quickly as possible. On a 3GS this is rather instant, but on a 3G it can take about 2 seconds. In the latter case of the 3G, the user is looking at a black screen for that time. Is this behavior allowed by Apple? Is there any way to alter this SDK example so that it makes use of 'default.png'? It doesn't seem so straight forward to me. I want my user to see an image as quickly as possible, and I also don't want to be rejected for such a little quirk like this as well. In the guidelines, they encourage you to use default.png for standard applications to show a sort of mockup of the interface while it actually loads. I want to initialize OpenGL, and ALSO display this. This default.png is loaded before the app screen launches. This is EXACLTY what I want to make use of. Any help is appreciated. Thanks!

  • Odd "Object reference not set to an instance of an object" involving xWinForms

    - by Kyle
    Hey, I've been trying to get the xWinForms 3.0 library (a library with forms support in xna) working with my C# XNA Game project but I keep getting the same problem. I add the reference to my project, put in the using statement, declare a formCollection variable and then I try to initialize it. whenever I run the project I get stopped on this line: formCollection = new FormCollection(this.Window, Services, ref graphics); it gives me the error: " System.NullReferenceException was unhandled Message="Object reference not set to an instance of an object." Source="Microsoft.Xna.Framework" StackTrace: at Microsoft.Xna.Framework.Graphics.VertexShader..ctor(GraphicsDevice graphicsDevice, Byte[] shaderCode) at Microsoft.Xna.Framework.Graphics.SpriteBatch.ConstructPlatformData() at Microsoft.Xna.Framework.Graphics.SpriteBatch..ctor(GraphicsDevice graphicsDevice) at xWinFormsLib.FormCollection..ctor(GameWindow window, IServiceProvider services, GraphicsDeviceManager& graphics) at GameSolution.Game2.LoadContent() in C:\Users\Owner\Documents\School\Year 3\Winter\Soen 390\TeamWTF_3\SourceCode\GameSolution\GameSolution\Game2.cs:line 45 at Microsoft.Xna.Framework.Game.Initialize() at GameSolution.Game2.Initialize() in C:\Users\Owner\Documents\School\Year 3\Winter\Soen 390\TeamWTF_3\SourceCode\GameSolution\GameSolution\Game2.cs:line 37 at Microsoft.Xna.Framework.Game.Run() at GameSolution.Program.Main(String[] args) in C:\Users\Owner\Documents\School\Year 3\Winter\Soen 390\TeamWTF_3\SourceCode\GameSolution\GameSolution\Program.cs:line 14 InnerException: " In a project I downloaded that used the xWinForms, I put the following code in and it compiled and ran no error. but when I put it in my project I get the error. Am I making some stupid mistake about including dlls or something? I've been at this for hours and I can't seem to find anything that would cause this. using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Audio; using Microsoft.Xna.Framework.Content; using Microsoft.Xna.Framework.GamerServices; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Input; using Microsoft.Xna.Framework.Media; using Microsoft.Xna.Framework.Net; using Microsoft.Xna.Framework.Storage; using xWinFormsLib; namespace GameSolution { public class Game2 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; FormCollection formCollection; public Game2() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; } protected override void Initialize() { // TODO: Add your initialization logic here base.Initialize(); } protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. spriteBatch = new SpriteBatch(GraphicsDevice); formCollection = new FormCollection(this.Window, Services, ref graphics); } protected override void Update(GameTime gameTime) { base.Update(gameTime); } protected override void Draw(GameTime gameTime) { base.Draw(gameTime); } } } Any help would be greatly appreciated ._.
