  • Android: Find coordinates of a certain point X meters from my location moving towards the point I am

    - by Aidan
    Hi Guys, I'm constructing a geolocation based application and I'm trying to figure out a way to make my application realise when a user is facing the direction of the given location (a particular long / lat co-ord). I've done some Googling and checked the SDK but can't really find anything for such a thing. Does anyone know of a way? Example. Point A = Phones current location. Point B = A's orientation in relation to true north + 45 + max distance towards the direction your facing, Point C = A's orientation in relation to true north - 45 + max distance towards the direction your facing. So now you have a triangle constructed. pretty schweet huh? yeah.. I think so.. So now that I have my fancy Triangle I use something called Barycentric Coordinates ( http://en.wikipedia.org/wiki/Barycentric_coordinates_(mathematics) ). This will allow me to test another point and see if it is in the triangle. If it is, it means we're facing it AND it's within the right distance. So it should be displayed on screen. If I'm facing 90 degrees from true north. The distance it travels should be that direction. 90 degrees from true north. It should not be 100 degrees or something from true north! But the problem is I haven't yet figured out how I make the device realise it must go "out" the direction it is facing.

  • How to avoid nested functions when using AJAX?

    - by Fletcher Moore
    Sequential Asynchronous calls are gross. Is there a more readable solution? The problem is this is hard to follow: ajaxOne(function() { // do something ajaxTwo(function() { // do something ajaxThree() }); }); where the anonymous functions are callbacks that are called on server response. I'm using a third party API to make the AJAX calls, so I need a generic solution.

  • Is there any difference between var name = function() {} & function name() {} in Javascript?

    - by Fletcher Moore
    Suppose we are inside a function and not in the global namespace. function someGlobalFunction() { var utilFunction1 = function() { } function utilFunction2 () { } utilFunction1(); utilFunction2(); } Are these synonymous? And do these functions completely cease to exist when someGlobalFunction returns? Should I prefer one or the other for readability or some other reason?

  • Find if a user is facing a certain Location using Digital Compass by constructing a triangle and usi

    - by Aidan
    Hi Guys, I'm constructing a geolocation based application and I'm trying to figure out a way to make my application realise when a user is facing the direction of the given location (a particular long / lat co-ord). I've done some Googling and checked the SDK but can't really find anything for such a thing. Does anyone know of a way? To clarify Android knows my location, the second location and my orientation. What I want is a way for Android to recognise when my orientation is "facing" the second location (e.g within 90 Degrees or so). We're also assuming that the user is stationary and needs updates every second or so therefore getBearing(); is useless. Alright so we get it has to be math, there appears to be no simple SDK stuff we can use. I did some searching of my own and found Barycentric Co-ords http://www.blackpawn.com/texts/pointinpoly/default.html . So what I'm trying to do now is map the camera's field of view. For Example if the person is facing a certain direction the program should construct a triangle around that field of view, e.g it should make one vertices the phone's position and then go out either side for a set distance making the 2 end points vertices constructing a triangle. If I had this I could then apply Barycentric co-ords to see if the point lay within the newly constructed triangle. Idea's anyone? Example. I could get my current orientation, add 45 to it and go up X distance one side and subtact 45 and go up X distance the other side to find my 2 other points. Though, how would I make android know which way it should go "up" I guess? It would know its baring as this stage so I need it to recognise it's bearing and go out that direction.

  • SensorManager method crashes program

    - by Aidan
    Hi guys, When I run the following method my Android application crashes. I can't find the error because I get a "Source Not Found" error. Anyone have any idea's what I'm doing wrong? public void bearing(){ SensorManager sm = (SensorManager)getSystemService(Context.SENSOR_SERVICE); Sensor aSensor = sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); Sensor mfSensor = sm.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD); sm.registerListener(myAccelerometerListener, aSensor, SensorManager.SENSOR_DELAY_UI); sm.registerListener(myMagneticFieldListener, mfSensor, SensorManager.SENSOR_DELAY_UI); float[] values = new float[3]; float[] R = new float[9]; SensorManager.getRotationMatrix(R, null, accelerometerValues, magneticFieldValues); SensorManager.getOrientation(R, values); //Convert from Radians to degrees values[0] = (float) Math.toDegrees(values[0]); values[1] = (float) Math.toDegrees(values[1]); values[2] = (float) Math.toDegrees(values[2]); }

  • Perl Email package

    - by aidan
    I'm looking for a simple (OO?) approach to email creation and sending. Something like $e = Email->new(to => "test <[email protected]>", from => "from <[email protected]>"); $e->plain_text($plain_version); $e->html($html_version); $e->attach_file($some_file_object); I've found Email::MIME::CreateHTML, which looks great in almost every way, except that it does not seem to support file attachments. Also, I'm considering writing these emails to a database and having a cronjob send them at a later date. This means that I would need a $e->as_text() sub to return the entire email, including attachments, as raw text which I could stuff into the db. And so I would then need a way of sending the raw emails - what would be a good way of achieving this? Many thanks

  • Android onFling not responding

    - by Kevin Moore
    I am new to android first of all so think of any newbie mistakes first I am trying to add a fling function in my code. public class MainGamePanel extends SurfaceView implements SurfaceHolder.Callback, OnGestureListener { private MainThread thread; private Droid droid; private Droid droid2; private static final String TAG = gameView.class.getSimpleName(); private GestureDetector gestureScanner; public MainGamePanel(Context context){ super(context); getHolder().addCallback(this); droid = new Droid(BitmapFactory.decodeResource(getResources(), R.drawable.playerbox2), 270, 300); droid2 = new Droid(BitmapFactory.decodeResource(getResources(), R.drawable.playerbox2), 50, 300); thread = new MainThread(getHolder(), this); setFocusable(true); gestureScanner = new GestureDetector(this); } public boolean onTouchEvent(MotionEvent event){ return gestureScanner.onTouchEvent(event); } @Override protected void onDraw(Canvas canvas){ canvas.drawColor(Color.BLACK); droid.draw(canvas); droid2.draw(canvas); } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { droid.setX(50); droid.setY(50); Log.d(TAG, "Coords: x=" + e1.getX() + ",y=" + e2.getY()); return true; } @Override public boolean onDown(MotionEvent e) { droid2.setX((int)e.getX()); droid2.setY((int)e.getY()); Log.d(TAG, "Coords: x=" + e.getX() + ",y=" + e.getY()); return false; } I got the gestureListener to work with: onDown, onLongPress, and onShowPress. But i can't get any response with onFling, onSingleTapUp, and onScroll. What mistake am I making? does it have to do with views? I don't know what code would be useful to see.... so any suggestions would be much appreciated. Thank You!

  • Call OnDraw in another method, then "refresh" that call in ANOTHER method.

    - by Aidan
    Hey guys, Hopefully this will actually make sense and sorry if its a stupid / obvious question. Basically I'm calling the onDraw method like so... requestWindowFeature(Window.FEATURE_NO_TITLE); Preview mPreview = new Preview(this); DrawOnTop mDraw = new DrawOnTop(this); setContentView(mPreview); addContentView(mDraw, new LayoutParams (LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); You see I'm drawing it on top of a Camera view and the information being drawn is subject to change. I have a listener setup which will update the variables being drawn at the appropriate time but I now want to "refresh" this draw in that listener. How would I do such a thing?

  • Password generation, best practice

    - by Aidan
    I need to generate some passwords, I want to avoid characters that can be confused for each other. Is there a definitive list of characters I should avoid? my current list is il10o8B3Evu![]{} Are there any other pairs of characters that are easy to confuse? for special characters I was going to limit myself to those under the number keys, though I know that this differs depending on your keyboards nationality! As a rider question, I would like my passwords to be 'wordlike'do you have a favoured algorithm for that? Thanks :)

  • Use external inline script as local function

    - by Aidan
    Had this closed once as a duplicate, yet the so-called duplicate DID NOT actually address my whole question. I have found this script that, when run inline, returns your IP. <script type="text/javascript" src="http://l2.io/ip.js"></script> http://l2.io/ip.js Has nothing more than a line of code that says document.write('123.123.123.123'); (But obviously with the user's IP address) I want to use this IP address as a return string for a function DEFINED EXTERNALLY, BUT STILL ON MY DOMAIN. That is, I have a "scripts.js" that contains all the scripts I wish to use, and I would like to include it in that list as a local function that calls to the 12.io function, but javascript won't allow the < tags, so I am unsure as to how to do this. I.e. function getIP() { return (THAT SCRIPT'S OUTPUT); } This is the topic this was supposedly a duplicate of, and it is very similar. Get ip address with javascript However, this DOES NOT address defining as a forwarded script it in my own script file.

  • Why does SQL Server consider N'????' and N'???' to be equal?

    - by Aidan Ryan
    We are testing our application for Unicode compatibility and have been selecting random characters outside the Latin character set for testing. On both Latin and Japanese-collated systems the following equality is true (U+3422): N'????' = N'???' but the following is not (U+30C1): N'????' = N'???' This was discovered when a test case using the first example (using U+3422) violated a unique index. Do we need to be more selective about the characters we use for testing? Obviously we don't know the semantic meaning of the above comparisons. Would this behavior be obvious to a native speaker?

  • Should comments say WHY the program is doing what it is doing? (opinion on a dictum by the inventor of Forth)

    - by AKE
    The often provocative Chuck Moore (inventor of the Forth language) gave the following advice (paraphrasing): "Use comments sparingly. Programs are self-documenting, with a modicum of help from mnemonics. Comments should say WHAT the program is doing, not HOW." My question: Should comments say WHY the program is doing what it is doing? Update: In addition to the answers below, these two provide additional insight. Beginner's guide to writing comments? http://programmers.stackexchange.com/a/98609/62203

  • Aligning music notes using String matching algorithms or Dynamic Programming

    - by Dolphin
    Hi I need to compare 2 sets of musical pieces (i.e. a playing-taken in MIDI format-note details extracted and saved in a database table, against sheet music-taken into XML format). When evaluating playing against sheet music (i.e.note details-pitch, duration, rhythm), note alignment needs to be done - to identify missed/extra/incorrect/swapped notes that from the reference (sheet music) notes. I have like 1800-2500 notes in one piece approx (can even be more-with polyphonic, right now I'm doing for monophonic). So will I have to have all these into an array? Will it be memory overloading or stack overflow? There are string matching algorithms like KMP, Boyce-Moore. But note alignment can also be done through Dynamic Programming. How can I use Dynamic Programming to approach this? What are the available algorithms? Is it about approximate string matching? Which approach is much productive? String matching algos like Boyce-Moore, or dynamic programming? How can I assess which is more effective? Greatly appreciate any insight or suggestions Thanks in advance
