• solve a classic map-reduce problem with opencl?

  - by liuliu

  I am trying to parallel a classic map-reduce problem (which can parallel well with MPI) with OpenCL, namely, the AMD implementation. But the result bothers me. Let me brief about the problem first. There are two type of data that flow into the system: the feature set (30 parameters for each) and the sample set (9000+ dimensions for each). It is a classic map-reduce problem in the sense that I need to calculate the score of every feature on every sample (Map). And then, sum up the overall score for every feature (Reduce). There are around 10k features and 30k samples. I tried different ways to solve the problem. First, I tried to decompose the problem by features. The problem is that the score calculation consists of random memory access (pick some of the 9000+ dimensions and do plus/subtraction calculations). Since I cannot coalesce memory access, it costs. Then, I tried to decompose the problem by samples. The problem is that to sum up overall score, all threads are competing for few score variables. It keeps overwriting the score which turns out to be incorrect. (I cannot carry out individual score first and sum up later because it requires 10k * 30k * 4 bytes). The first method I tried gives me the same performance on i7 860 CPU with 8 threads. However, I don't think the problem is unsolvable: it is remarkably similar to ray tracing problem (for which you carry out calculation that millions of rays against millions of triangles). Any ideas?

• Mapping parent-child relationships with iBatis

  - by agnul

  I have the classic setup public class Parent { Integer id; ... // No generics Collection someCollectionAttribute; ... public void setChildren(Collection c) { ... } } public class Child { Integer id; ... } and I'm trying to map this on the usual table setup using iBatis (version 2.30... don't ask). create table parents ( ID integer primary key ... ) create table children ( ID integer primary key PARENT_ID integer references parents(id) ... ) My mapping file looks like this <resultMap id="ParentResult" groupBy="id"> <result property="id" column="ID" /> ... <result property="children" resultMap="ChildResult" /> </resultMap> <resultMap id="ChildResult"> <result property="id" column="ID" /> <result property="parentId" column="PARENT_ID" /> ... </result> <sql id="loadParent" resultMap="ParentResult"> select P.ID as p1, ..., C.ID as c1, C.PARENT_ID as c2 ... from parents P join children C on (P.ID = C.PARENT_ID) where P.ID = #id# order by P.ID </sql> Doing the usual sqlMap.queryForObject("loadParent", new Integer(42)) at first caused a NullPointerException inside the setChildren setter which apparently is called with a null argument (my bad). Fixing the setter everything works fine, but the logs show that setChildren is called only once before even running a single SQL statement, still with a null argument, so I'm wondering what's going on here. Anyone has any clues?

• iPhone MailComposer class UIViewController dismissModalViewControllerAnimated issues

  - by Scott Pendleton

  I created a class to launch the MailComposer so that my iPhone app would only have one place to go when generating various kinds of e-mail: some with attachments, some not. Some with pre-filled addresses, some not. I didn't want my class implement UIViewController, but it has to so it can be the delegate for the MailComposer. Otherwise, the view controllers that call my class would themselves have to be delegates for the MailComposer, which defeats the purpose. The downside of having my class be a view controller is that it has to load to the screen before it can modally bring up the MailComposer. Unfortunately, view controllers can't be transparent. The effect is, whatever is on screen gets covered by a solid white view controller for a moment before the MailComposer appears. I could maybe live with that, but not this: after the MailComposer goes away, I'm left with my blank view controller occupying the screen. I ought to be able to get rid of it from within itself by calling this: [self.parentViewController dismissModalViewControllerAnimated:NO]; But that dies a horrible death: "Loading 43365 stack frames..." Has my class -- a UIViewController that pre-fills and then launches a MailComposer -- lost track of its parentViewController? It isn't nil, because I've tested for that. As launched from within the current view controller... // My class is called Email. Email *oEmail = [[[Email alloc] init] retain]; // Red, to remind myself that I'd like to someday learn to make it transparent. oEmail.view.backgroundColor = [UIColor redColor]; // Pre-fill whatever fields you want, and specify attachments. oEmail.EmailSubject = @"I am truly stumped"; // This has to go on screen first. [self presentModalViewController:oEmail animated:NO]; // Then this can happen, which brings up the MailComposer. [oEmail f_SendEmail]; // Commenting out the next line didn't help, so I turned it back on. [oEmail release]; Inside the class, you need the mailComposeController:didFinishWithResult:error: method to make the MailComposer go away, and for that to happen, the class has to be the MFMailComposeViewControllerDelegate. Here's what happens in there: // This gets rid of the mail composer. [self dismissModalViewControllerAnimated:YES]; // This never fails to get rid of other modal view controllers when called // from within those controllers, but boy does it not work here. [self.parentViewController dismissModalViewControllerAnimated:NO]; If you can help me, I will be truly thankful!

• Dictionary is returning false on ContainsKey after item is added

  - by Karel Frajtak

  I have a dictionary declared as follows IDictionary<string, object> _objectIds = new Dictionary<string, object>(); I was experiencing some problems with it and it discovered that the instance returned false as a result of ContainsKey method and from the watch window I was sure that the item was there. So I created helper method private bool IdsContainsKey(string key) { lock (syncObject) { lock (_objectIds) { if (_objectIds.ContainsKey(key)) return true; // A if (_objectIds.ContainsKey(key)) return true; // B return _objectIds.ContainsKey(key); // C } } } During my debugging session I run into situation when the method exited in place B and sometimes I made to C returning true. Can anybody help me? Thanks.

• Generating all unique combinations for "drive ya nuts" puzzle

  - by Yuval A

  A while back I wrote a simple python program to brute-force the single solution for the drive ya nuts puzzle. The puzzle consists of 7 hexagons with the numbers 1-6 on them, and all pieces must be aligned so that each number is adjacent to the same number on the next piece. The puzzle has ~1.4G non-unique possibilities: you have 7! options to sort the pieces by order (for example, center=0, top=1, continuing in clockwise order...). After you sorted the pieces, you can rotate each piece in 6 ways (each piece is a hexagon), so you get 6**7 possible rotations for a given permutation of the 7 pieces. Totalling: 7!*(6**7)=~1.4G possibilities. The following python code generates these possible solutions: def rotations(p): for i in range(len(p)): yield p[i:] + p[:i] def permutations(l): if len(l)<=1: yield l else: for perm in permutations(l[1:]): for i in range(len(perm)+1): yield perm[:i] + l[0:1] + perm[i:] def constructs(l): for p in permutations(l): for c in product(*(rotations(x) for x in p)): yield c However, note that the puzzle has only ~0.2G unique possible solutions, as you must divide the total number of possibilities by 6 since each possible solution is equivalent to 5 other solutions (simply rotate the entire puzzle by 1/6 a turn). Is there a better way to generate only the unique possibilities for this puzzle?

• How to “unbind” .result on Jquery Autocomplete?

  - by Cesar

  I have this code: $("#xyz").unautocomplete().autocomplete(dataVar, { minChars: 0, width: 400, matchContains: true, highlightItem: true, formatItem: formatItem, formatResult: formatResult }) .result(findValueCallback).next().click(function() { $(this).prev().search(); }); I call this code many times and the first call works correctly, but after he calls findValueCallback many times, not once more. The unautocomplete don't clear .result What I have to do for call findValueCallback once? Sample Code: var niveis01 = []; var niveis02 = []; var niveis03 = []; $(document).ready(function(){ carregaDadosNivel1(); }); function carregaDadosNivel1() { $.ajax({ url: "http://.....", cache: true, type: "POST", dataType:"json", success: function(data){ ... niveis01 = data; habilitaComboNivel1(); ... }, error: function(xhr, ajaxOptions, thrownError){ ... } }); } function habilitaComboNivel1() { function findValueCallback1(event, data01, formatted) { ... carregaDadosNivel2(); ... } $("#nivel01").unautocomplete().autocomplete(niveis01, { minChars: 0, width: 400, matchContains: true, highlightItem: true, formatItem: formatItem, formatResult: formatResult }).result(findValueCallback1).next().click(function() { $(this).prev().search(); }); } function carregaDadosNivel2() { $.ajax({ url: "http://.....", cache: true, type: "POST", dataType:"json", success: function(data){ ... niveis02 = data; habilitaComboNivel2(); ... }, error: function(xhr, ajaxOptions, thrownError){ ... } }); } function habilitaComboNivel2() { function findValueCallback2(event, data02, formatted) { ... carregaDadosNivel3(); ... } $("#nivel02").unautocomplete().autocomplete(niveis02, { minChars: 0, width: 400, matchContains: true, highlightItem: true, formatItem: formatItem, formatResult: formatResult }).result(findValueCallback2).next().click(function() { $(this).prev().search(); }); } function carregaDadosNivel3() { $.ajax({ url: ""http://.....", cache: true, type: "POST", dataType:"json", success: function(data){ ... niveis03 = data; habilitaComboNivel3(); ... }, error: function(xhr, ajaxOptions, thrownError){ ... } }); } function habilitaComboNivel3() { function findValueCallback3(event, data03, formatted) { ... } $("#nivel03").unautocomplete().autocomplete(niveis03, { minChars: 0, width: 400, matchContains: true, highlightItem: true, formatItem: formatItem, formatResult: formatResult }).result(findValueCallback3).next().click(function() { $(this).prev().search(); }); }

• Need help programming with Mclauren series and Taylor series!

  - by user352258

  Ok so here's what i have so far: #include <stdio.h> #include <math.h> //#define PI 3.14159 int factorial(int n){ if(n <= 1) return(1); else return(n * factorial(n-1)); } void McLaurin(float pi){ int factorial(int); float x = 42*pi/180; int i, val=0, sign; for(i=1, sign=-1; i<11; i+=2){ sign *= -1; // alternate sign of cos(0) which is 1 val += (sign*(pow(x, i)) / factorial(i)); } printf("\nMcLaurin of 42 = %d\n", val); } void Taylor(float pi){ int factorial(int); float x; int i; float val=0.00, sign; float a = pi/3; printf("Enter x in degrees:\n"); scanf("%f", &x); x=x*pi/180.0; printf("%f",x); for(i=0, sign=-1.0; i<2; i++){ if(i%2==1) sign *= -1.0; // alternate sign of cos(0) which is 1 printf("%f",sign); if(i%2==1) val += (sign*sin(a)*(pow(x-a, i)) / factorial(i)); else val += (sign*cos(a)*(pow(x-a, i)) / factorial(i)); printf("%d",factorial(i)); } printf("\nTaylor of sin(%g degrees) = %d\n", (x*180.0)/pi, val); } main(){ float pi=3.14159; void McLaurin(float); void Taylor(float); McLaurin(pi); Taylor(pi); } and here's the output: McLaurin of 42 = 0 Enter x in degrees: 42 0.733038-1.00000011.0000001 Taylor of sin(42 degrees) = -1073741824 I suspect the reason for these outrageous numbers goes with the fact that I mixed up my floats and ints? But i just cant figure it out...!! Maybe its a math thing, but its never been a strength of mine let alone program with calculus. Also the Mclaurin fails, how does it equal zero? WTF! Please help correct my noobish code. I am still a beginner...

• Java Robot key activity seems to stop working while certain software is running

  - by Mike Turley

  I'm writing a Java application to automate character actions in an online game overnight (specifically, it catches fish in Final Fantasy XI). The app makes heavy use of java's Robot class both for emulating user keyboard input and for detecting color changes on certain parts of the screen. It also uses multithreading and a swing GUI. The application seems to work perfectly when I test it without the game running, just using screenshots to trigger the apps responses into notepad. But for some reason, when I actually launch FFXI and start the program, all of my keyboard and mouse manipulations just stop working altogether. The program is still running, and the Robot class is still able to read pixel colors. But Robot.keyPress, Robot.keyRelease, Robot.mouseMove, Robot.mousePress and Robot.mouseRelease all do nothing. It's the strangest thing-- to test it, I wrote a simple loop that just keeps typing letters, and focused notepad. I'd then start the game, refocus notepad, and it would do nothing. Then I'd exit the game, and it'd start working again immediately. Has anyone else come across something like this, where specific software will stop certain functions of java from working? Also, to make this more interesting-- Last year I wrote a very similar program using the same classes and programming techniques to automate healing a party in the game as they fight. Last year, this program worked perfectly. After running into these problems I dug up that old program, ran it without making any changes, and found that it too was having the same problems. The only differences between now and when it was working: I was running Windows Vista and now I'm running Windows 7, and several new Java versions as well as FFXI versions have been released. What the hell is going on? (if anyone needs to see my source code, email me at [email protected]. I'm trying to keep it to myself.)

• How do I fix JavaHL (JNI) Not available after I have changed the logon password on my Mac?

  - by INeedHelp

  I have installed Eclipse 3.5.2 and the plugin Subversion JavaHL Native Library Adapter 1.6.9.2 and this worked without any problems. However, this morning I was forced to change the password to logon to my Mac and since then I get the message that "Subversion native library not available" when I try to save any changes. Can anyone help? I have tried to add this line (-Djava.library.path=/usr/lib/jni) to the eclipse.ini file but this didn´t seem to make any difference. Can anyone help?

• Closest Approach question for math/physics heads

  - by Kyle

  I'm using a Segment to Segment closest approach method which will output the closest distance between two segments of length. These objects are moving at variable speed each, so even when it succeeds I'm currently using a 10-step method and calculating the distance between 2 spheres as they move along the two segments. So, basically the length of each segment is the object's traverse in the physics step, and the radius is the objects radius. By stepping, I can tell where they collide, and if they collide (Sort of; for the MOST part.).. I get the feeling that there could be something better. While I sort of believe that the first closest approach call is required, I think that the method immediately following it is a TAD weak. Can anyone help me out? I can illustrate this if needed. Thanks alot!

• There is no attachment in the sent mail by iPhone

  - by naruhodo

  I'm trying to send a recorded sound file as attachment with MFMailComposeViewController. The sound file is OK. The picker shows the correct file name, shows the audio file icon as attachment, sends the mail, but there is no attachment in the result. I attached below the source of the sent mail. There is a "text/plain" content type part instead of "Content-Disposition: attachment;" as expected. This is my code code to define the path and attach the audio file. What could be wrong? #define DOCUMENTS_FOLDER [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] #define FILEPATH [DOCUMENTS_FOLDER stringByAppendingPathComponent:[self dateString]] ... NSURL *url = [NSURL fileURLWithPath:FILEPATH]; self.recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error]; ... MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; NSURL *url = [NSURL fileURLWithPath: [NSString stringWithFormat:@"%@", [self.recorder url]]]; NSData *audioData = [NSData dataWithContentsOfFile:[url path]]; [picker addAttachmentData:audioData mimeType:@"audio/wav" fileName:[[url path] lastPathComponent]]; and the source of the sent mail: Content-type: multipart/mixed; boundary=Apple-Mail-1-614960740 Content-transfer-encoding: 7bit MIME-version: 1.0 (iPod Mail 7E18) Subject: Sound message: Date: Sun, 11 Apr 2010 11:58:56 +0200 X-Mailer: iPod Mail (7E18) --Apple-Mail-1-614960740 Content-Type: text/plain;     charset=us-ascii;     format=flowed Content-Transfer-Encoding: 7bit It is a text here --Apple-Mail-1-614960740 Content-Type: text/plain;     charset=us-ascii;     format=flowed Content-Transfer-Encoding: 7bit Sent from my iPod --Apple-Mail-1-614960740--

• What Does OSGi Solve?

  - by Pablo Fernandez

  I've read on wikipedia and other sites about OSGi, but I don't really see the big picture. It says that it's a component based platform, and that you can reload modules at runtime. Also the "practical example" given everywhere is the Eclipse Plugin Framework. My questions are: 1) What is the CLEAR and SIMPLE definition of OSGi? 2) What COMMON PROBLEMS does it solve? By "common problems" I mean problems we face everyday, like "what can OSGi do for making our jobs more efficient/fun/simple" Thanks.

• XHtml Strict, Float: Center ?

  - by Axel Myers

  Hi everyone. I'm having hard time with Xhtml Strict 1.0 and Css. And I'm almost out of solutions. My Site Url: http://www.pro-turk.net/beta/ I made a jquery multilevel dropdown menu for my site. It looks like OK, but I have used inline-block property of css display attribute on navigation menu which is a part of css 2.1 and isn't supported by some browsers (including ie6 and ie7). I want to make #nav li elements block level elements, but to do this and having all of them in same line, the only way is using float in #nav li. But I want to center them in their parent (the menu bar). So I need something like float:center (I know it's pretty stupid and doesn't exist). But is there a way to include block level elements as children elements without linebreaks (I mean without making a block level element). Regards.

• best practices - multiple functions vs single function with switch case

  - by Amit

  I have a situation where I need to perform several small (but similar) tasks. I can think of two ways to achieve this. First Approach: function doTask1(); function doTask2(); function doTask3(); function doTask4(); Second Approach: // TASK1, TASK2, ... TASK4 are all constants function doTask(TASK) { switch(TASK) { case TASK1: // do task1 break; case TASK2: // do task2 break; case TASK3: // do task3 break; case TASK4: // do task4 break; } } A few more tasks may be added in future (though the chances are rare. but this cannot be ruled out) Please suggest which of the two approaches (or if any other) is a best practice in such a situation.

• Strange Ruby String Selection

  - by Daniel

  The string in question (read from a file): if (true) then { _this = createVehicle ["Land_hut10", [6226.8901, 986.091, 4.5776367e-005], [], 0, "CAN_COLLIDE"]; _vehicle_10 = _this; _this setDir -2.109278; }; Retrieved from a large list of similar (all same file) strings via the following: get_stringR(string,"if","};") And the function code: def get_stringR(a,b,c) b = a.index(b) b ||= 0 c = a.rindex(c) c ||= b r = a[b,c] return r end As so far, this works fine, but what I wanted to do is select the array after "createVehicle", the following (I thought) should work. newstring = get_string(myString,"\[","\];") Note get_string is the same as get_stringR, except it uses the first occurrence of the pattern both times, rather then the first and last occurrence. The output should have been: ["Land_hut10", [6226.8901, 986.091, 4.5776367e-005], [], 0, "CAN_COLLIDE"]; Instead it was the below, given via 'puts': ["Land_hut10", [6226.8901, 986.091, 4.5776367e-005], [], 0, "CAN_COLLIDE"]; _vehicle_10 = _this; _this setDir Some 40 characters past the point it should have retrieve, which was very strange... Second note, using both get_string and get_stringR produced the exact same result with the parameters given. I then decided to add the following to my get_string code: b = a.index(b) b ||= 0 c = a.index(c) c ||= b if c 40 then c -= 40 end r = a[b,c] return r And it works as expected (for every 'block' in the file, even though the strings after that array are not identical in any way), but something obviously isn't right :).

• jQuery Flip! links inside divs

  - by JLee

  Hey there. I want to use Flip (http://lab.smashup.it/flip/) for one of my projects. But I want the links to make the flip action inside the divs that are going to be flipped. I stumbled across a question here and the reply was very helpful, and by using that codes I managed to achieve what I want. But now the issue is when the page first loads it automatically flips before clicking any link. I don't know much about jQuery. So I would appreciate any help.

  - by Johua

  Hy people. I'm working on my webapp for the iphone. On some point you have the option to get a particular document from our appserver. It works on firefox, but safari just shows an empty download window. IE also can't get the file. Below is the example link. Is there something wrong with a link of this kind that Safari can't see? http://192.168.200.32:9999/USER_STORAGE?user=bt&token=bEVfjg%2FGHoHHU2CxmAWyiTXFUgN9kN2o8pEKgCFV5Fw%3D&nonce=9jJgj4qGXB4U7m%2FJXjjsmbfreH2J2nT8D789jHY6zro%3D&parent_session=cjDEN3PvltsAqjiagynS8mN6HKeAgqWv82WJqxWiXD8%3D&method=download&filename=Testdokument2
