• EXC_BAD_INSTRUCTION (SIGILL) at random during use of app. Bug in AppKit?

  - by Ger Teunis

  I'm currently testing a new version of an app of mine on OSX 10.5 An user reported some weird crashes during use of the application, sadly not reproducible by me. At first sight it seems to happen randomly, once he had the crash while opening an NSOpenPanel and once during focusing an NSTextField and once during NSView switch in a parent view. If you have any idea which area I should look at it would be greatly appreciated! I'm completely lost here. App is compiled in XCode 3.2.1 with SDK 10.5 and targetted at 10.5 He send me these crashes: Crash 1 Process: NZBVortex [43622] Path: /Users/cero/Downloads/NZBVortex.app/Contents/MacOS/NZBVortex Identifier: com.NZBVortex.NZBVortex Version: 0.5.5 (0.5.5) Code Type: X86-64 (Native) Parent Process: launchd [97] Interval Since Last Report: 1951 sec Crashes Since Last Report: 1 Per-App Interval Since Last Report: 1858 sec Per-App Crashes Since Last Report: 1 Date/Time: 2010-03-23 23:43:49.671 +0100 OS Version: Mac OS X 10.5.8 (9L31a) Report Version: 6 Anonymous UUID: 98AB0386-590B-4E0D-B7AC-3F7AA4E7238E Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Crashed Thread: 0 Application Specific Information: objc[43622]: alt handlers in objc runtime are buggy! - Hide quoted text - Thread 0 Crashed: 0 libobjc.A.dylib 0x00007fff82baef6e _objc_fatal + 238 1 libobjc.A.dylib 0x00007fff82bb2ea4 objc_addExceptionHandler + 302 2 com.apple.CoreFoundation 0x00007fff842b1090 _CFDoExceptionOperation + 528 3 com.apple.AppKit 0x00007fff81f75e26 _NSAppKitLock + 81 4 com.apple.AppKit 0x00007fff81f80f8f -[NSView nextKeyView] + 56 5 com.apple.AppKit 0x00007fff81f81018 -[NSView _primitiveSetNextKeyView:] + 72 6 com.apple.AppKit 0x00007fff820732b1 -[NSView _recursiveSetDefaultKeyViewLoop] + 242 7 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 8 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 9 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 10 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 11 com.apple.AppKit 0x00007fff82072fc3 -[NSView _setDefaultKeyViewLoop] + 279 12 com.apple.AppKit 0x00007fff82072e70 -[NSWindow recalculateKeyViewLoop] + 36 13 com.apple.AppKit 0x00007fff821dd149 -[NSSavePanel(NSSavePanelRuntime) _loadPreviousModeAndLayout] + 39 14 com.apple.AppKit 0x00007fff821dcf9e -[NSSavePanel(NSSavePanelRuntime) runModalForDirectory:file:types:] + 71 15 com.NZBVortex.NZBVortex 0x000000010000b7ee -[MainWindowViewController openNZBFileButtonClick:] + 62 16 com.apple.AppKit 0x00007fff821c96bf -[NSToolbarButton sendAction:to:] + 77 17 com.apple.AppKit 0x00007fff821c8bb7 -[NSToolbarItemViewer mouseDown:] + 5362 18 com.apple.AppKit 0x00007fff82082783 -[NSWindow sendEvent:] + 5068 19 com.apple.AppKit 0x00007fff8204fd46 -[NSApplication sendEvent:] + 5089 20 com.apple.AppKit 0x00007fff81faa562 -[NSApplication run] + 497 21 com.apple.AppKit 0x00007fff81f772f0 NSApplicationMain + 373 22 com.NZBVortex.NZBVortex 0x0000000100012a69 main + 9 23 com.NZBVortex.NZBVortex 0x0000000100001a84 start + 52 Crash 2 Process: NZBVortex [43600] Path: /Users/cero/Downloads/NZBVortex.app/Contents/MacOS/NZBVortex Identifier: com.NZBVortex.NZBVortex Version: 0.5.5 (0.5.5) Code Type: X86-64 (Native) Parent Process: launchd [97] Interval Since Last Report: 727 sec Crashes Since Last Report: 1 Per-App Interval Since Last Report: 616 sec Per-App Crashes Since Last Report: 1 Date/Time: 2010-03-23 23:11:20.000 +0100 OS Version: Mac OS X 10.5.8 (9L31a) Report Version: 6 Anonymous UUID: 98AB0386-590B-4E0D-B7AC-3F7AA4E7238E Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Crashed Thread: 0 Application Specific Information: objc[43600]: alt handlers in objc runtime are buggy!

• Android Map Performance poor because of many Overlays?

  - by Dave

  Hi, I have a map in my android application that shows many markers (~20-50). But the app performs very poor when i try to scroll/zoom (in Google Android Maps i did a sample search for pizza and there were also some 20-50 results found and i didn't notice any particular performance problems when zooming/scrolling through the map). Here is my (pseudo)code: onCreate() { .... drawable = this.getResources().getDrawable(R.drawable.marker1); itemizedOverlay = new MyItemizedOverlay(drawable,mapView); ... callWebServiceToRetrieveData(); createMarkers(); } createMarkers(){ for(elem:bigList){ GeoPoint geoPoint = new GeoPoint((int)(elem.getLat()*1000000), (int) (elem.getLon()*1000000)); OverlayItem overlayItem = new OverlayItem(geoPoint, elem.getName(), elem.getData()); itemizedOverlay.addOverlay(overlayItem); mapOverlays.add(itemizedOverlay); } mapView.invalidate(); } the MyItemizedOverlay.addOverlay looks like this: public void addOverlay(OverlayItem overlay) { m_overlays.add(overlay); populate(); }

• SQL DATEDIFF Not working!?

  - by James

  Hi all, I am running a simple DATEDIFF query but it doesn't seem to calculate the days properly or i'm doing something wrong. If I run PRINT DATEDIFF(Day, 2010-01-20, 2010-01-01) RETURN 19 Which is correct. If i change the month in the first date to Feb (02) I get something strange. PRINT DATEDIFF(Day, 2010-02-20, 2010-01-01) RETURN 20 Now shouldn't it be 48 or something? Can anyone see what i'm doing wrong or is this not the correct function to be using if I want the No of days between these dates? I've tried taking one date from the other: PRINT (2010-02-20) - (2010-01-01) RETURN -20 Any help much appreciated. Thanks J.

• How do I translate this Matlab bsxfun call to R?

  - by claytontstanley

  I would also (fingers crossed) like the solution to work with R Sparse Matrices in the Matrix package. >> A = [1,2,3,4,5] A = 1 2 3 4 5 >> B = [1;2;3;4;5] B = 1 2 3 4 5 >> bsxfun(@times, A, B) ans = 1 2 3 4 5 2 4 6 8 10 3 6 9 12 15 4 8 12 16 20 5 10 15 20 25 >> EDIT: I would like to do a matrix multiplication of these sparse vectors, and return a sparse array: > class(NRowSums) [1] "dsparseVector" attr(,"package") [1] "Matrix" > class(NColSums) [1] "dsparseVector" attr(,"package") [1] "Matrix" > NRowSums * NColSums (I think) w/o using a non-sparse variable to temporarily store data.

  Hi, I have a WCF service deployed on a windows 2003 server. We are using a WPF application to consume this service. The trouble is if we deploy a new version of WCF service or leave the IIS and WPF application idle for sometime and then try to execute a functionality, we are get the following exception: The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8).

• C++ floating point precision

  - by Davinel

  double a = 0.3; std::cout.precision(20); std::cout << a << std::endl; result: 0.2999999999999999889 double a, b; a = 0.3; b = 0; for (char i = 1; i <= 50; i++) { b = b + a; }; std::cout.precision(20); std::cout << b << std::endl; result: 15.000000000000014211 So.. 'a' is smaller than it should be. But if we take 'a' 50 times - result will be bigger than it should be. Why is this? And how to get correct result in this case?

So if one then of course it goes to case 1. If there are 2 opened then it moves the oldest down and puts the newest on top. etc etc. I have set it so that a max of 6 boxes can only be opened at one time. If anyone knows how i could also "slide" them down (kinda like an effect of jQuery) then that would also be, well awesome to know! :o) Any help/suggestions would be great! :o) David

• Why the CCLayer can't use a for loop in draw method??

  - by Tattat

  I have a CClayer, that have a draw method, every second, it will call the draw method 60 times. So, I have method like this: -(void)draw{ glEnable(GL_LINE_SMOOTH); glColor4f(0.0f, 1.0f, 0.0f, 1.0f); glLineWidth(5.0f); ccDrawLine(ccp(300,20), CGPointZero); } I work great. but after I added a for looop, for example....: -(void)draw{ glEnable(GL_LINE_SMOOTH); glColor4f(0.0f, 1.0f, 0.0f, 1.0f); glLineWidth(5.0f); ccDrawLine(ccp(300,20), CGPointZero); for(int i=0; i<5; i++){ NSLog(@"Testing the loop, %i", i); } } It can't draw anything, the screen only black. But I can see the Testing the loop is keep calling.... Why? thank you.

• Django South Foreign Keys referring to pks with Custom Fields

  - by Rory Hart

  I'm working with a legacy database which uses the MySQL big int so I setup a simple custom model field to handle this: class BigAutoField(models.AutoField): def get_internal_type(self): return "BigAutoField" def db_type(self): return 'bigint AUTO_INCREMENT' # Note this won't work with Oracle. This works fine with django south for the id/pk fields (mysql desc "| id | bigint(20) | NO | PRI | NULL | auto_increment |") but the ForeignKey fields in other models the referring fields are created as int(11) rather than bigint(20). I assume I have to add an introspection rule to the BigAutoField but there doesn't seem to be a mention of this sort of rule in the documentation (http://south.aeracode.org/docs/customfields.html). Update: Currently using Django 1.1.1 and South 0.6.2

• Cron syntax with Java EE 5?

  - by marabol

  Timer Tasks in Java EE are not very comfortable. Is there any util, to configure timer with cron syntax like "0 20 20 * * "? I wonder, if it would be a good way to use Quartzinside (clustered) JEE application. According to http://www.prozesse-und-systeme.de/serverClustering.html (german page) there limits with Quartz and Java EE clustering: JDBC must be used as job store for Quartz Only cluster associated Quartz instances are allowed to use this JDBC job store All cluster nodes must be synchronized to the split second All cluster nodes must use the same quartz.properties file I would prefer an easier way for configuration of timer service, instead an not Java EE managed scheduler.

• Working with expression AST:s

  - by Marcus

  Hi, Is there any best practice when working with AST:s? I have a parsed expression AST. ConstantExpression, BinaryExpression etc. I want to populate a GUI-dialog with information from the AST, and it's here where I get kinda confused because my code gets pretty messy. Example: expression = "Var1 > 10 AND Var2 < 20" I want to populate two textboxes with value 10 resp. 20 from the AST. What I'm doing now is a recursive method that checks for correct child expression-types (with .Net Is-operator) and acts accordingly and the code is really "smelly" :) Is there any design pattern, like Visitor or such, that makes this somewhat easier/more readable/maintainable ?

• Diophantine Equation

  - by lakshmi

  Show that it is possible to buy exactly 50, 51, 52, 53, 54, and 55 McNuggets, by finding solutions to the Diophantine equation. You can solve this in your head, using paper and pencil, or writing a program. However you chose to solve this problem, list the combinations of 6, 9 and 20 packs of McNuggets you need to buy in order to get each of the exact amounts. Given that it is possible to buy sets of 50, 51, 52, 53, 54 or 55 McNuggets by combinations of 6, 9 and 20 packs, show that it is possible to buy 56, 57,..., 65 McNuggets. In other words, show how, given solutions for 50-55, one can derive solutions for 56-65.python

• Slow Execution of an ASP.NET Web Page

  - by Sweta Jha

  I have a web page which brings 13K+ records in 20 seconds. There is a menu on the page, clicking on which navigates me to another page which is very lightweight. Displaying the data (13K+) took only 20 seconds whereas navigating from that page took much longer, more than 2 mins. Can you tell me why is the latter taking so much of time. I've stopped the page_load code execution on click of the menu. I've disabled the viewstate for that page as well.

• Date Picker Blue

  - by Matt Winters

  I'm successfully setting a date-picker with an initial date from a plist, but I see some unwanted blue values in the month, day, and year components, presumably corresponding to current date. So if today is April 18, 2010 and initial date being set is March 19, 2008, it looks like this (bold represents the blue): January 17 2006 February 18 2007 ------------------------------ March 19 2008 ------------------------------ April 20 2009 May 21 2010 First question is: How do I get rid of the blue? And second question: Ideally, how do I get it to look like this? January 17 2006 February 18 2007 ------------------------------ March 19 2008 ------------------------------ April 20 2009 May 21 2010 Third question, totally unrelated and not as important: How could I have gotten the above to show in blue rather than bold? I see blue in code snippets all the time. Matt

  i really don't get the point how to use predicates in zend framework 2. this is what i got: $sql->select() ->columns(array('GroupedColum' ,'minValue' => new Expression('min(ValueColumn)'))) ->from('ValueTable') ->group('GroupedColum') ->order('minValue') ->order('GroupedColum') ->limit(10); this is working fine now i want to apply somethin like that: $predicate = new Zend\Db\Sql\Predicate\Predicate(); $sql->where($predicate->greaterThan('filterColumn','20); this is what i tried, it throws no error, but it is not working :-( This is what i expect as SQL: select GroupedColum , min(ValueColumn) as minValue from ValueTable where filterColumn > 20 group by GroupedColum order by minValue GroupedColum limit 10;

• Web Safe Area (optimal resolution) for web app design

  - by M.A.X

  I'm in the process of designing a new web app and I'm wondering for what 'web safe area' should I optimize the app layout and design. I did some investigation and thinking on my own but wanted to share this to see what the general opinion is. Here is what I found: Optimal Display Resolution: w3schools web stats seems to be the most referenced source (however they state that these are results from their site and is biased towards tech savvy users) http://www.w3counter.com/globalstats.php (aggregate data from something like 15,000 different sites that use their tracking services) StatCounter Global Stats Display Resolution (Stats are based on aggregate data collected by StatCounter on a sample exceeding 15 billion pageviews per month collected from across the StatCounter network of more than 3 million websites) NetMarketShare Screen Resolutions (marketshare.hitslink.com) (a web analytics consulting firm, they get data from browsers of site visitors to their on-demand network of live stats customers. The data is compiled from approximately 160 million visitors per month) Display Resolution Summary: There is a bit of variation between the above sources but in general as of Jan 2011 looks like 1024x768 is about 20%, while ~85% have a higher resolution of at least 1280x768 (1280x800 is the most common of these with 15-20% of total web, depending on the source; 1280x1024 and 1366x768 follow behind with 9-14% of the share). My guess would be that the higher resolution values will be even more common if we filter on North America, and even higher if we filter on N.American corporate users (unfortunately I couldn't find any free geographically filtered statistics). Another point to note is that the 1024x768 desktop user population is likely lower than the aforementioned 20%, seeing as the iPad (1024x768 native display) is likely propping up those number. My recommendation would be to optimize around the 1280x768 constraint (*note: 1280x768 is actually a relatively rare resolution, but I think it's a valid constraint range considering that 1366x768 is relatively common and 1280 is the most common horizontal resolution). Browser + OS Constraints: To further add to the constraints we have to subtract the space taken up by the browser (assuming IE, which is the most space consuming) and the OS (assuming WinXP-Win7): Win7 has the biggest taskbar footprint at a height of 40px (XP's and Vista's is 30px) The default IE8 view uses up 25px at the bottom of the screen with the status bar and a further 120px at the top of the screen with the windows title bar and the browser UI (assuming the default 'favorites' toolbar is present, it would instead be 91px without the favorites toolbar). Assuming no scrollbar, we also loose a total of 4px horizontally for the window outline. This means that we are left with 583px of vertical space and 1276px of horizontal. In other words, a Web Safe Area of 1276 x 583 Is this a correct line of thinking? I tried to Google some design best practices but most still talk about designing around 1024x768 which seems to be quickly disappearing. Any help on this would be greatly appreciated! Thanks.
