  • Crash on replacing map annotations

    - by Alwin
    Solved it, see below code I'm trying to replace annotations on my MapView depending on the distance between user location and annotation. The annotations are getting replaced like they should, but when I touch te mapview my app crashes. This is de code I have so far: NSMutableArray *tempArray = [[NSMutableArray alloc] init]; for (id object in self.mapAnnotations) { if([object isKindOfClass:[ClosedAnnotation class]]) { ClosedAnnotation *ann = (ClosedAnnotation *)object; CLLocation *tempLocation = [[CLLocation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude]; double distance = [self.currentLocation getDistanceFrom: tempLocation] / 1000; [tempLocation release]; if(distance <= 1.0){ [mapView removeAnnotation:object]; OpenAnnotation *openAnnotation = [[OpenAnnotation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude imageSrc:[ann getImageSrcForAnnotation] title:ann.title tekst:[ann getTextForAnnotation] imageSize:[ann getSizeForImage] username:[ann getUserNameForAnnotation] usertext:[ann getUserTextForAnnotation]]; [mapView addAnnotation:openAnnotation]; [tempArray addObject:openAnnotation]; [openAnnotation release]; } else { [tempArray addObject:object]; } } else if([object isKindOfClass:[OpenAnnotation class]]){ OpenAnnotation *ann = (OpenAnnotation *)object; CLLocation *tempLocation = [[[CLLocation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude] autorelease]; double distance = [self.currentLocation getDistanceFrom: tempLocation] / 1000; [tempLocation release]; if(distance > 1.0){ [mapView removeAnnotation:object]; ClosedAnnotation *closedAnnotation = [[ClosedAnnotation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude imageSrc:[ann getImageSrcForAnnotation] title:ann.title tekst:[ann getTextForAnnotation] imageSize:[ann getSizeForImage] username:[ann getUserNameForAnnotation] usertext:[ann getUserTextForAnnotation]]; [mapView addAnnotation:closedAnnotation]; [tempArray addObject:closedAnnotation]; [closedAnnotation release]; } else { [tempArray addObject:object]; } } } [self.mapAnnotations removeAllObjects]; [self.mapAnnotations addObjectsFromArray:tempArray]; [tempArray release]; I solved it by getting rid of the complete "two-class"-structure and handling everything within one annotation class. Works like a charm now.

  • Ann Arbor Day of .NET 2010 Recap

    - by PSteele
    Had a great time at the Ann Arbor Day of .NET on Saturday.  Lots of great speakers and topics.  And chance to meet up with friends you usually only communicate with via email/twitter. My Presentation I presented "Getting up to speed with C# 3.5 — Just in time for 4.0!".  There's still a lot of devs that are either stuck in .NET 2.0 or just now moving to .NET 3.5.  This presentation gave highlights of a lot of the key features of 3.5.  I had great questions from the audience.  Afterwards, I talked with a few people who are just now getting in to 3.5 and they told me they had a lot of "A HA!" moments when something I said finally clicked and made sense from a code sample they had seen on the web.  Thanks to all who attended! A few people have asked me for the slides and demo.  The slides were nothing more than a table of contents.  90% of the presentation was spent inside Visual Studio demo'ing new techniques.  However, I have included it in the ZIP file with the sample solution.  You can download it here. Dennis Burton on MongoDB I caught Dennis Burton's presentation on MongoDB.  I was really interested in this one as I've missed the last few times Dennis had given it to local user groups.  It was very informative and I want to spend some time learning more about MongoDB.  I'm still an old-school relational guy, but I'm willing to investigate alternatives. Brian Genisio on Prism Since I'm not a Silverlight/WPF guy (yet), I wasn't sure this would interest me.  But I talked with Brian for a couple of minutes before the presentation and he convinced me to catch it.  And I'm glad he did.  Prism looks like a very nice framework for "composable UI's" in Silverlight and WPF.  I like the whole "dependency injection" feel to it.  Nice job Brian! GiveCamp Planning I spent some time Saturday working on things for the upcoming GiveCamp (which is why I only caught a few sessions).  Ann Arbor's Day of .NET and GiveCamp have both been held at Washtenaw Community College so I took some time (along with fellow GiveCamp planners Mike Eaton and John Hopkins) to check out the new location for Ann Arbor GiveCamp this year! In the past, WCC has let us use the Business Education (BE) building for our GiveCamp's.  But this year, they're moving us over to the Morris Lawrence (ML) building.  Let me tell you – this is a step UP!  In the BE building, we were spread across two floors and spread out into classrooms.  Plus, our opening and closing ceremonies were held in the Liberal Arts (LA) building – a bit of a walk from the BE building. In the ML building, we're together for the whole weekend.  We've got a large open area (which can be sectioned off if needed) for everyone to work in:   Right next to that, we have a large area where we can set up tables and eat.  And it helps that we have a wonderful view while eating (yes, that's a lake out there with a fountain): The ML building also has showers (which we'll have access to!) and it's own auditorium for our opening and closing ceremonies. All in all, this year's GiveCamp will be great! Stay tuned to the Ann Arbor GiveCamp website.  We'll be looking for volunteers (devs, designers, PM's, etc…) soon!

  • Talks Submitted for Ann Arbor Day of .NET 2010

    - by PSteele
    Just submitted my session abstracts for Ann Arbor's Day of .NET 2010.   Getting up to speed with .NET 3.5 -- Just in time for 4.0! Yes, C# 4.0 is just around the corner.  But if you haven't had the chance to use C# 3.5 extensively, this session will start from the ground up with the new features of 3.5.  We'll assume everyone is coming from C# 2.0.  This session will show you the details of extension methods, partial methods and more.  We'll also show you how LINQ -- Language Integrated Query -- can help decrease your development time and increase your code's readability.  If time permits, we'll look at some .NET 4.0 features, but the goal is to get you up to speed on .NET 3.5.   Go Ahead and Mock Me! When testing specific parts of your application, there can be a lot of external dependencies required to make your tests work.  Writing fake or mock objects that act as stand-ins for the real dependencies can waste a lot of time.  This is where mocking frameworks come in.  In this session, Patrick Steele will introduce you to Rhino Mocks, a popular mocking framework for .NET.  You'll see how a mocking framework can make writing unit tests easier and leads to less brittle unit tests.   Inversion of Control: Who's got control and why is it being inverted? No doubt you've heard of "Inversion of Control".  If not, maybe you've heard the term "Dependency Injection"?  The two usually go hand-in-hand.  Inversion of Control (IoC) along with Dependency Injection (DI) helps simplify the connections and lifetime of all of the dependent objects in the software you write.  In this session, Patrick Steele will introduce you to the concepts of IoC and DI and will show you how to use a popular IoC container (Castle Windsor) to help simplify the way you build software and how your objects interact with each other. If you're interested in speaking, hurry up and get your submissions in!  The deadline is Monday, April 5th! Technorati Tags: .NET,Ann Arbor,Day of .NET

  • ANN for decompiler?

    - by Rhythmic Algorithm
    Has there ever been any attempts at utilizing artificial neural networks in decompilation? It would be nice if it was possible to provide the trimmed semantics of source along with the code in to a neural network so it could learn the connection between the two. I assume this would likely lose it's effectiveness when there is optimizations and maybe work better for high level languages too but I'm interested in hearing any attempts anyone has had at this.

  • Why Java language does not offer a way to declare getters and setters of a given "field" through ann

    - by zim2001
    I actually happily design and develop JEE Applications for quite 9 years, but I realized recently that as time goes by, I feel more and more fed up of dragging all these ugly bean classes with their bunch of getters and setters. Considering a basic bean like this : public class MyBean { // needs getter AND setter private int myField1; // needs only a getter, no setter private int myField2; // needs only a setter, no getter private int myField3; /** * Get the field1 * @return the field1 */ public int getField1() { return myField1; } /** * Set the field1 * @param value the value */ public void setField1(int value) { myField1 = value; } /** * Get the field2 * @return the field2 */ public int getField2() { return myField2; } /** * Set the field3 * @param value the value */ public void setField3(int value) { myField3 = value; } } I'm dreaming of something like this : public class MyBean { @inout(public,public) private int myField1; @out(public) private int myField2; @in(public) private int myField3; } No more stupid javadoc, just tell the important thing... It would still be possible to mix annotation and written down getters or setters, to cover cases when it should do non-trivial sets and gets. In other words, annotation would auto-generate the getter / setter code piece except when a literate one is provided. Moreover, I'm also dreaming of replacing things like that : MyBean b = new MyBean(); int v = b.getField1(); b.setField3(v+1); by such : MyBean b = new MyBean(); int v = b.field1; b.field3 = v+1; In fact, writing "b.field1" on the right side of an expression would be semantically identical to write "b.getField1()", I mean as if it has been replaced by some kind of a preprocessor. It's just an idea but I'm wondering if I'm alone on that topic, and also if it has major flaws. I'm aware that this question doesn't exactly meet the SO credo (we prefer questions that can be answered, not just discussed) so I flag it community wiki...

  • Neural Network problems

    - by Betamoo
    I am using an external library for Artificial Neural Networks in my project.. While testing the ANN, It gave me output of all NaN (not a number in C#) The ANN has 8 input , 5 hidden , 5 hidden , 2 output, and all activation layers are of Linear type , and it uses back-propagation, with learning rate 0.65 I used one testcase for training { -2.2, 1.3, 0.4, 0.5, 0.1, 5, 3, -5 } ,{ -0.3, 0.2 } for 1000 epoch And I tested it on { 0.2, -0.2, 5.3, 0.4, 0.5, 0, 35, 0.0 } which gave { NaN , NaN} Note: this is one example of many that produces same case... I am trying to discover whether it is a bug in the library, or an illogical configuration.. The reasons I could think of for illogical configuration: All layers should not be linear Can not have descending size layers, i.e 8-5-5-2 is bad.. Only one testcase ? Values must be in range [0,1] or [-1,1] Is any of the above reasons could be the cause of error, or there are some constraints/rules that I do not know in ANN designing..? Note: I am newbie in ANN

  • Is my client correct that I cannot take a vacation as a subcontractor? [closed]

    - by Rae Ann
    I have 2 clients who I do ongoing work for as a subcontractor. Both are sporadic and part-time. Company A sent me to a 3 day certification course out of state. The following week I was scheduled for a 3 day vacation. I warned company B three weeks prior to these events. During my training that Company A was paying for, Company B asked me to leave the training to workon something for them that needed immediate attention. I declined. However I made arrangements to work on it in the evening and in the early mornings after they threatened to take the work and all subsequent work for this client to someone else. I lost all networking and fun from that trip... The following week I was in Florida and was again asked to do more work on the project after the feedback from the client. The integrated product personnel would not cooperate/return any of our calls so I did the best I could. I turned in the work, explained the issue and then was gone for 3 hours. When I returned, all my access to the project had been revoked and after a week of my calls and emails I found out they replaced me. I sent an invoice 3 weeks ago and they tell me they owe me nothing because I did not do the whole project and they cannot bill the client for what I did, because they are billing for the second contractor who started over. I was told that they realize I was on vacation but as a subcontractor I lose the ability to just disappear. I was gone 3 hours! Is this normal, correct, legal?? Not only did they ruin my class and my vacation, but now they expect me to not demand payment? They ended our relationship and I was in the middle of another project of theirs too. They told me to immediately cease all work for them. How do I get paid for the work I have yet to invoice this month?

  • We Found 100 Manufacturing Heros That Focus on Innovation!

    - by Stephen Slade
    There’s a good piece written by Ann Grackin of ChainLink Research on the Manufacturing Leadership 100 Awards program held recently in Palm Beach Fl, Apr 30-May 3, 2012.  This article (link below) highlights the summary of the Summit with specific focus on manufacturing innovation.  There were several informative keynotes and sessions from industrial leaders who are leveraging the latest tools and technologies to make better decisions. Ann writes that she was a panelist with Cindy Reese, SVP, Worldwide Operations, Oracle; and Steven Tungate, VP/GM, Supply Chain & Innovation, Toshiba America Business Solutions about Factories and Supply Networks of the Future. Ann writes “So what are these manufacturers doing? Significant rationalization of the supply base (Toshiba, especially, has this issue since they have a long history of many acquisitions), streamlining production to increase productivity, and looking for lower-cost countries for manufacturing….  No doubt firms have global customer bases, so they need to be present in these markets. However, a low-cost-country manufacturing source does introduce more risk in the supply chain. And that was discussed. Quality, security, and intellectual property protection were the critical global manufacturing issues also discussed. “Cindy (Reese) told a fascinating story about Oracle’s acquisition of Sun and the supply chain that was subsequently created. Here was one of the key points: Although Oracle sells on a global basis, they now do their own factory-installed software. This keeps potential ‘factory-installed malware’ from getting into the servers at contract manufacturers, and prevents pirated software. In this way, Oracle ensures that they deliver the quality and security people expect”.

  • Acer Aspire One (mini) mfgd 9/03 locks up also when plugged in

    - by LAURIE ANN
    My problem is almost the same as the Toshiba user (Toshiba A205-5804 freezes when plugged in): Well I have a Toshiba A205-5804 and the problem is that the screen freezes anytime I plug the pc into the external power supply, not as most of the computers having the same issue, my computer DOES freeze in safe mode, and I really can't bear this problem for much longer... It's not an overheat problem, the computer is not getting hot or anything related, I've tried already to change the AC adapter, to boot only with AC and no battery, and also all of these suggestions: The only difference in my case is: I can be using the battery and when it runs down, I can just close the lid and the system goes into hibernation mode. I then plug it in and let it charge. When I think it's finally charged, I can UNPLUG it, open the lid and all is running fine on the battery again. Note: the system was NOT shut down and it still runs as long as I remove the power plug before opening the lid. I have ALL the same issues as the other Toshiba user, also. I was a tech for 9 yrs in my own business and this one has not only stumped me, but anyone I have asked has never heard of this problem. Every repair center wants to charge me for diagnosis, even is they cannot fix it. I would really like to run this system along side of my new Acer Aspire 17" laptop as I need it to finish my grad school work. Any ideas would be GREATLY appreciated. Thanx, Laurie Ann

  • iPhone Objective C - error: pointer value used where a floating point value was expected

  • How can I pass latitude and longitude values from UIViewController to MKMapView?

    - by jerincbus
    I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAction)goToMapView { MapViewController *mapController = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil]; mapController.mapAddress = self.address; mapController.mapTitle = self.Title; mapController.mapLat = self.lat; mapController.mapLng = self.lng; //Push the new view on the stack [[self navigationController] pushViewController:mapController animated:YES]; [mapController release]; //mapController = nil; } And on my MapViewController.h file I have: #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #import "DetailViewController.h" #import "CourseAnnotation.h" @class CourseAnnotation; @interface MapViewController : UIViewController <MKMapViewDelegate> { IBOutlet MKMapView *mapView; NSString *mapAddress; NSString *mapTitle; NSNumber *mapLat; NSNumber *mapLng; } @property (nonatomic, retain) IBOutlet MKMapView *mapView; @property (nonatomic, retain) NSString *mapAddress; @property (nonatomic, retain) NSString *mapTitle; @property (nonatomic, retain) NSNumber *mapLat; @property (nonatomic, retain) NSNumber *mapLng; @end And on the pertinent parts of the MapViewController.m file I have: @synthesize mapView, mapAddress, mapTitle, mapLat, mapLng; - (void)viewDidLoad { [super viewDidLoad]; [mapView setMapType:MKMapTypeStandard]; [mapView setZoomEnabled:YES]; [mapView setScrollEnabled:YES]; MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center.latitude = mapLat; //40.105085; region.center.longitude = mapLng; //-83.005237; region.span.longitudeDelta = 0.01f; region.span.latitudeDelta = 0.01f; [mapView setRegion:region animated:YES]; [mapView setDelegate:self]; CourseAnnotation *ann = [[CourseAnnotation alloc] init]; ann.title = mapTitle; ann.subtitle = mapAddress; ann.coordinate = region.center; [mapView addAnnotation:ann]; } But I get this when I try to build: 'error: incompatible types in assignment' for both lat and lng variables. So my questions are am I going about passing the variables from one view to another the right way? And does the MKMapView accept latitude and longitude as a string or a number?

  • Tricky SQL query involving consecutive values

    - by Gabriel
    I need to perform a relatively easy to explain but (given my somewhat limited skills) hard to write SQL query. Assume we have a table similar to this one: exam_no | name | surname | result | date ---------+------+---------+--------+------------ 1 | John | Doe | PASS | 2012-01-01 1 | Ryan | Smith | FAIL | 2012-01-02 <-- 1 | Ann | Evans | PASS | 2012-01-03 1 | Mary | Lee | FAIL | 2012-01-04 ... | ... | ... | ... | ... 2 | John | Doe | FAIL | 2012-02-01 <-- 2 | Ryan | Smith | FAIL | 2012-02-02 2 | Ann | Evans | FAIL | 2012-02-03 2 | Mary | Lee | PASS | 2012-02-04 ... | ... | ... | ... | ... 3 | John | Doe | FAIL | 2012-03-01 3 | Ryan | Smith | FAIL | 2012-03-02 3 | Ann | Evans | PASS | 2012-03-03 3 | Mary | Lee | FAIL | 2012-03-04 <-- Note that exam_no and date aren't necessarily related as one might expect from the kind of example I chose. Now, the query that I need to do is as follows: From the latest exam (exam_no = 3) find all the students that have failed (John Doe, Ryan Smith and Mary Lee). For each of these students find the date of the first of the batch of consecutively failing exams. Another way to put it would be: for each of these students find the date of the first failing exam that comes after their last passing exam. (Look at the arrows in the table). The resulting table should be something like this: name | surname | date_since_failing ------+---------+-------------------- John | Doe | 2012-02-01 Ryan | Smith | 2012-01-02 Mary | Lee | 2012-01-04 Ann | Evans | 2012-02-03 How can I perform such a query? Thank you for your time.
