  • Browser compatibility; Before or after uploading website to server?

    - by Camran
    I am on the stage where I need to make my website cross-browser compatible. I need tips on how to get started. I have developed my website on firefox, so it works great with firefox. I guess I have to download a couple of versions of all major browsers now, right? Then just test each browser one by one? Should I do this before uploading the entire website onto a server or afterwards? All tips and SW which makes this easier is appreciated. BTW, it is a classifieds website using MySql, Solr, PHP, js etc... Thanks

  • Command prompt in debug mode for Eclipse? (OpenCV + Eclipse + Win7)

    - by Tony
    I am a beginner for Eclipse. I now have Eclipse C/C++ IDE with OpenCV library running on Windows 7. So far it works after spending hours trying to get it running. But then I realize that Eclipse does not pop up a command prompt as VS2010 does while debugging. And moreover Eclipse's debug mode is just stuck in there and refuse to output anything. But if the code doesn't involve the OpenCV things it works again. Below is the code I use for testing. It captures images from webcam and output it to the screen. The infinite loop (until you press 'q') makes sure it constantly grabs new inputs from the camera. I browsed through the workspace and run the exe just compiled and it worked flawlessly. So I don't think there's anything wrong in the code (it's an example code anyway In brief, can I just pop up a command prompt window in debug mode? And why is Eclipse console stuck when the code involves some OpenCV functions? #include <stdio.h> #include <stdlib.h> #include <tchar.h> #include <cv.h> #include <cxcore.h> #include <highgui.h> #include <iostream> int _tmain(int argc, _TCHAR* argv[]) { CvCapture *capture = 0; IplImage *frame = 0; int key = 0; /* initialize camera */ capture = cvCaptureFromCAM( 0 ); /* always check */ if ( !capture ) { printf("Cannot open initialize webcam!\n"); return 1; } /* create a window for the video */ cvNamedWindow( "result", CV_WINDOW_AUTOSIZE ); while( key != 'q' ) { /* get a frame */ frame = cvQueryFrame( capture ); /* always check */ if( !frame ) break; /* display current frame */ cvShowImage( "result", frame ); /* exit if user press 'q' */ key = cvWaitKey( 1 ); } /* free memory */ cvDestroyWindow( "result" ); cvReleaseCapture( &capture ); return 0; }

  • jtreg update, March 2012

    - by jjg
    There is a new update for jtreg 4.1, b04, available. The primary changes have been to support faster and more reliable test runs, especially for tests in the jdk/ repository. [ For users inside Oracle, there is preliminary direct support for gathering code coverage data using jcov while running tests, and for generating a coverage report when all the tests have been run. ] -- jtreg can be downloaded from the OpenJDK jtreg page: http://openjdk.java.net/jtreg/. Scratch directories On platforms like Windows, if a test leaves a file open when the test is over, that can cause a problem for downstream tests, because the scratch directory cannot be emptied beforehand. This is addressed in agentvm mode by discarding any agents using that scratch directory and starting new agents using a new empty scratch directory. Successive directives use suffices _1, _2, etc. If you see such directories appearing in the work directory, that is an indication that files were left open in the preceding directory in the series. Locking support Some tests use shared system resources such as fixed port numbers. This causes a problem when running tests concurrently. So, you can now mark a directory such that all the tests within all such directories will be run sequentially, even if you use -concurrency:N on the command line to run the rest of the tests in parallel. This is seen as a short term solution: it is recommended that tests not use shared system resources whenever possible. If you are running multiple instances of jtreg on the same machine at the same time, you can use a new option -lock:file to specify a file to be used for file locking; otherwise, the locking will just be within the JVM used to run jtreg. "autovm mode" By default, if no options to the contrary are given on the command line, tests will be run in othervm mode. Now, a test suite can be marked so that the default execution mode is "agentvm" mode. In conjunction with this, you can now mark a directory such that all the tests within that directory will be run in "othervm" mode. Conceptually, this is equivalent to putting /othervm on every appropriate action on every test in that directory and any subdirectories. This is seen as a short term solution: it is recommended tests be adapted to use agentvm mode, or use "@run main/othervm" explicitly. Info in test result files The user name and jtreg version info are now stored in the properties near the beginning of the .jtr file. Build The makefiles used to build and test jtreg have been reorganized and simplified. jtreg is now using JT Harness version 4.4. Other jtreg provides access to GNOME_DESKTOP_SESSION_ID when set. jtreg ensures that shell tests are given an absolute path for the JDK under test. jtreg now honors the "first sentence rule" for the description given by @summary. jtreg saves the default locale before executing a test in samevm or agentvm mode, and restores it afterwards. Bug fixes jtreg tried to execute a test even if the compilation failed in agentvm mode because of a JVM crash. jtreg did not correctly handle the -compilejdk option. Acknowledgements Thanks to Alan, Amy, Andrey, Brad, Christine, Dima, Max, Mike, Sherman, Steve and others for their help, suggestions, bug reports and for testing this latest version.

  • Ubuntu VM "read only file system" fix?

    - by David
    I was going to install VMWare tools on an Ubuntu server Virtual Machine, but I ran into the issue of not being able to create a cdrom directory in the /mnt directory. I then tested to see if it was just a permissions issue, but I couldn't even create a folder in the home directory. It continues to state that it is a read only file system. I know a little about Linux, and I'm not comfortable with it yet. Any advice would be much appreciated.

  • How do I use key combinations on an axis on a joystick in xorg?

    - by valadil
    I'm using xserver-xorg-input-joystick on Debian Stable so I can use a joystick in place of the mouse. I have mouse movement working correctly, but got stuck trying to add functions for some other keys. These work: #Left stick #Pointer Option "MapAxis1" "mode=relative axis=1.5x" Option "MapAxis2" "mode=relative axis=1.5y" #Right stick #Arrow keys Option "MapAxis4" "mode=relative keylow=Left keyhigh=Right" Option "MapAxis5" "mode=relative keylow=Up keyhigh=Down" But when I try to make key combos (so I can navigate windows and screens in xmonad) I have no luck. #dpad #xmonad focus #up/down toggle window. l/r choose screen. Option "MapAxis8" "mode=relative keylow=Super_L,k keyhigh=Super_L,j" Option "MapAxis7" "mode=relative keylow=Super_L,w keyhigh=Super_L,e" I've also tried Super_R, plain old Super, Meta, and mod4mask, and anything else I can think of. These buttons print the letter, but don't appear to hold down the modifying key. The exception to that is shift. If I specify Shift_L or Shift_R, I get a capital letter. xev indicates that modifier keys are being pressed. If I lower Axis8, I get press Super_L, press k, release k, release Super_L. That looks like it should be working. Maybe this is an xmonad problem and not a joystick driver one? I'm also having trouble with getting an axis to use other XF86 keys: # triggers # song selection Option "MapAxis3" "mode=relative keylow=none keyhigh=XF86AudioForward" Option "MapAxis6" "mode=relative keylow=none keyhigh=XF86AudioBack" That does nothing. Any idea why? If it turns out that this isn't something I can do on an axis, but would work with a button, is there a way to treat my joysticks as buttons? Also, if anyone has suggestions for the other 5 buttons I'll have left after mouse buttons are bound, I'm listening.

  • Animation Color [on hold]

    - by user2425429
    I'm having problems in my java program for animation. I'm trying to draw a hexagon with a shape similar to that of a trapezoid. Then, I'm making it move to the right for a certain amount of time (DEMO_TIME). Animation and ScreenManager are "API" classes, and AnimationTest1 is a demo. In my test program, it runs with a black screen and white stroke color. I'd like to know why this happened and how to fix it.

  • ViewController has wrong orientation after Landscape-only has been popped

    - by noroom
    In a navigation-based app, LandscapeViewController only supports landscape mode (all others support both modes). I also have a "loading screen" that advises the user to rotate the phone before continuing. This way I can make sure that when my landscape view loads, that it's in landscape mode. The problem comes when i rotate the phone to portrait mode while still showing LandscapeVC. I press the Back nagivation button to navigate up one level (to a VC that supports both landscape and portrait modes), but the upper level shows in landscape mode even though the phone is in portrait mode. I guess this is because when I left this view I was in portrait mode, I then rotated the phone while in another view, so this view has not received the notification. If I then proceed to rotate the phone to the other landscape mode (say the LandscapeVC was loaded on its right side, so I'd rotate the upper VC from portrait to the left landscape mode), it will update. My question is: how can I notify this upper view that the phone was rotated, so when the user goes up after putting the phone in portrait mode, the upper view shows correctly?

  • CSS3PIE issues in IE6 and 8

    - by Gordon
    I'm using CSS3PIE to apply some rounded corners to elements in Internet Explorer that will get them by stylesheet in other browsers. I've run into some issues with it though. In IE8, I discovered that any element that had the PIE behaviour would behave strangely. The container would jump a few pixels to the right, but the content would stay in its original position, giving the appearance that the content had all shifted left relative to its container. This would be especially problematic on elements with no or small amounts of padding. I was able to hack my way around the problem in IE8 by using X-UA-Compatible, but I'd rather avoid this solution if at all possible. I don't have access to IE9 for testing but my understanding hacks like PIE aren't necessary and it would be wasteful to force a compatibility mode in a browser that doesn't need it. I have worse issues in IE6, with the PIE layout breaking down completely on a list that is set up to use display:inline; zoom:1; list items (to simulate inline-block, which works in IE8 and the other browsers). Here the borders of the list items get rendered in completely the wrong place. So ideally, I'd like to have PIE work properly in IE6, and in IE8 without having to resort to compatibility mode. As far as IE6 goes, a graceful fallback where PIE is just not applied will do. IE7 is the only browser where the page displays as intended. I can't provide an example page just at the moment unfortunately, I can add one later though. Follow up: Here are some screen grabs made with IE Tester. I'm hoping they will make things a little more clear for everybody. As you can see, IE7 is fine. However, in IE8, the containers are offset to the left relative to their content, and in IE6 the list elements (with the rounded 1 pixel border) are a complete mess! Full size versions for IE8, IE7 and IE6 are also available

  • What Apache/PHP configurations do you know and how good are they?

    - by FractalizeR
    Hello. I wanted to ask you about PHP/Apache configuration methods you know, their pros and cons. I will start myself: ---------------- PHP as Apache module---------------- Pros: good speed since you don't need to start exe every time especially in mpm-worker mode. You can also use various PHP accelerators in this mode like APC or eAccelerator. Cons: if you are running apache in mpm-worker mode, you may face stability issues because every glitch in any php script will lead to unstability to the whole thread pool of that apache process. Also in this mode all scripts are executed on behalf of apache user. This is bad for security. mpm-worker configuration requires PHP compiled in thread-safe mode. At least CentOS and RedHat default repositories doesn't have thread-safe PHP version so on these OSes you need to compile at least PHP yourself (there is a way to activate worker mpm on Apache). The use of thread-safe PHP binaries is considered experimental and unstable. Plus, many PHP extensions does not support thread-safe mode or were not well-tested in thread-safe mode. ---------------- PHP as CGI ---------------- This seems to be the slowest default configuration which seems to be a "con" itself ;) ---------------- PHP as CGI via mod_suphp ---------------- Pros: suphp allows you to execute php scipts on behalf of the script file owner. This way you can securely separate different sites on the same machine. Also, suphp allows to use different php.ini files per virtual host. Cons: PHP in CGI mode means less performance. In this mode you can't use php accelerators like APC because each time new process is spawned to handle script rendering the cache of previous process useless. BTW, do you know the way to apply some accelerator in this config? I heard something about using shm for php bytecode cache. Also, you cannot configure PHP via .htaccess files in this mode. You will need to install PECL htscanner for this if you need to set various per-script options via .htaccess (php_value / php_flag directives) ---------------- PHP as CGI via suexec ---------------- This configuration looks the same as with suphp, but I heard, that it's slower and less safe. Almost same pros and cons apply. ---------------- PHP as FastCGI ---------------- Pros: FastCGI standard allows single php process to handle several scripts before php process is killed. This way you gain performance since no need to spin up new php process for each script. You can also use PHP accelerators in this configuration (see cons section for comment). Also, FCGI almost like suphp also allows php processes to be executed on behalf of some user. mod_fcgid seems to have the most complete fcgi support and flexibility for apache. Cons: The use of php accelerator in fastcgi mode will lead to high memory consumption because each PHP process will have his own bytecode cache (unless there is some accelerator that can use shared memory for bytecode cache. Is there such?). FastCGI is also a little bit complex to configure. You need to create various configuration files and make some configuration modifications. It seems, that fastcgi is the most stable, secure, fast and flexible PHP configuration, however, a bit difficult to be configured. But, may be, I missed something? Comments are welcome!

  • How can I keep straight alpha during rendering particles?

    - by April
    Rencently,I was trying to save textures of 3D particles so that I can reuse the in 2D rendering.Now I had some problem with alpha channel.Some artist told me I that my textures should have unpremultiplied alpha channel.When I try to get the rgb value back,I got strange result.Some area went lighter and even totally white.I mainly focus on additive and blend mode,that is: ADDITIVE: srcAlpha VS 1 BLEND: srcAlpha VS 1-srcAlpha I tried a technique called premultiplied alpha.This technique just got you the right rgb value,its all you need on screen.As for alpha value,it worked well with BLEND mode,but not ADDITIVE mode.As you can see in parameters,BLEND mode always controlled its value within 1.While ADDITIVE mode cannot guarantee. I want proper alpha,but it just got too big or too small consider to rgb.Now what can I do?Any help will be great thankful. PS:If you don't understand what I am trying to do,there is a commercial software called "Particle Illusion".You can create various particles and then save the scene to texture,where you can choose to remove background of particles. Now,I changed the title.For some software like maya or AE,what I want is called [straight alpha].

  • Dot Net Nuke module works in "Edit" mode but not for "View": cache problem?

    - by Godeke
    I have a DNN task that simply runs some Javascript to compute a price based on a few input fields. This module works fine on our production site, but we had a company do a skin for us to improve the look of the site and the module fails under this new system. (DNN 05.06.00 (459) although it was 5.5 prior... I updated in a futile hope that it was a bug in the old revision.) What is incredibly odd about this is that the module works fine when I'm logged in to DNN and using the Edit mode as an administrator. In this case the small snippet of JavaScript loads fine and filling the fields results in a price. On the other hand it I click "View" (or more importantly, if I'm not logged in at all) the page loads a cached copy. Even odder, I have found the cache files in \Portals\2\Cache\Pages are generated and then only the cached data is being used. When the cached copy is loaded, the JavaScript doesn't appear (it is normally created via a Page.ClientScript.RegisterClientScriptBlock(). Additionally, the button which posts the data to the server doesn't execute any of the server side code (confirmed with a debugger) but instead just reloads the cached copy. If I manually delete the files in \Portals\2\Cache\Pages then everything works properly, but I have to do so after every page load: failing to do so simply loads the page as it was last generated repeatedly. Resetting the application (either via the UI or editing web.config) doesn't change this and clearing the cache from the Host Settings page doesn't actually clear these cached pages. I'm guessing that Edit mode bypasses the cache in some way, but I have gone as far as turning off all caching on the site (which is horrible for performance) and the cached version is still loaded. Has anyone seen anything like this? Shouldn't clearing the cache clear the files (I'm using the File provider for caching)? Shouldn't even a cached page go back to the server if the user posts back? EDIT: I should point out that permissions don't appear to be a problem on the cache directory... other pages cached output are deleted from this folder, just this page has this issue. EDIT 2: Clarifying some settings and conditions which I didn't provide. First, this module works fine in production under DNN 5.6.0. In our test environment with the consulting company's changes it fails (the changes are skin and page layout only in theory: the module source itself verifies as unchanged). All cache settings and the like have been verified the same between the two and we only resorted to setting the module cache to 0 and -1 (and disabling the test site's cache entirely) when we couldn't find another cause for the problem. I have watched the cache work correctly on many other pages in test: there is something about this page that is causing the problem. We have punted and are creating an installable skin based on the consultant's work as I suspect they have somehow corrupted the DNN install (database side I think).

  • "FOR UPDATE" v/s "LOCK IN SHARE MODE" : Allow concurrent threads to read updated "state" value of locked row

    - by shadesco
    I have the following scenario: User X logs in to the application from location lc1: call it Ulc1 User X (has been hacked, or some friend of his knows his login credential, or he just logs in from a different browser on his machine,etc.. u got the point) logs in at the same time from location lc2: call it Ulc2 I am using a main servlet which : - gets a connection from database pooling - sets autocommit to false - executes a command that goes through app layers: if all successful, set autocommit to true in a "finally" statement, and closes connection. Else if an exception happens, rollback(). In my database (mysql/innoDb) i have a "history" table, with row columns: id(primary key) |username | date | topic | locked The column "locked" has by default value "false" and it serves as a flag that marks if a specific row is locked or not. Each row is specific to a user (as u can see from the username column) So back to the scenario: --Ulc1 sends the command to update his history from the db for date "D" and topic "T". --Ulc2 sends the same command to update history from the db for the same date "D" and same topic "T" at the exact same time. I want to implement an mysql/innoDB locking system that will enable whichever thread arriving to do the following check: Is column "locked" for this row true or not? if true, return a message to the user that " he is already updating the same data from another location" if not true (ie not locked) : flag it as locked and update then reset locked to false once finished. Which of these two mysql locking techniques, will actually allow the 2nd arriving thread from reading the "updated" value of the locked column to decide wt action to take?Should i use "FOR UPDATE" or "LOCK IN SHARE MODE"? This scenario explains what i want to accomplish: - Ulc1 thread arrives first: column "locked" is false, set it to true and continue updating process - Ulc2 thread arrives while Ulc1's transaction is still in process, and even though the row is locked through innoDb functionalities, it doesn't have to wait but in fact reads the "new" value of column locked which is "true", and so doesn't in fact have to wait till Ulc1 transaction commits to read the value of the "locked" column(anyway by that time the value of this column will already have been reset to false). I am not very experienced with the 2 types of locking mechanisms, what i understand so far is that LOCK IN SHARE MODE allow other transaction to read the locked row while FOR UPDATE doesn't even allow reading. But does this read gets on the updated value? or the 2nd arriving thread has to wait the first thread to commit to then read the value? Any recommendations about which locking mechanism to use for this scenario is appreciated. Also if there's a better way to "check" if the row has been locked (other than using a true/false column flag) please let me know about it. thank you SOLUTION (Jdbc pseudocode example based on @Darhazer's answer) Table : [ id(primary key) |username | date | topic | locked ] connection.setautocommit(false); //transaction-1 PreparedStatement ps1 = "Select locked from tableName for update where id="key" and locked=false); ps1.executeQuery(); //transaction 2 PreparedStatement ps2 = "Update tableName set locked=true where id="key"; ps2.executeUpdate(); connection.setautocommit(true);// here we allow other transactions threads to see the new value connection.setautocommit(false); //transaction 3 PreparedStatement ps3 = "Update tableName set aField="Sthg" where id="key" And date="D" and topic="T"; ps3.executeUpdate(); // reset locked to false PreparedStatement ps4 = "Update tableName set locked=false where id="key"; ps4.executeUpdate(); //commit connection.setautocommit(true);

  • Apps crashing with EXC_BAD_ACCESS when changing to a custom keyboard layout

    I have a custom layout installed (svdvorak_mac6.keylayout). After a reboot another keyboard layout was selected, so I selected my usual one instead. This lead to a lot of apps suddenly starting to crash (Chrome, Skype, Adium etc). I can change to any other built in layout for OS X, but as soon as I choose one custom installed one (either form ~/Library/Keyboard Layouts/ or from /Library/Keyboard Layouts/) the apps crash. The only thing I can remember that I did before the reboot was to install Google's video chat plugin for the browser. Here's the crash report from Adium: Process: Adium [372] Path: /Applications/Adium.app/Contents/MacOS/Adium Identifier: com.adiumX.adiumX Version: 1.4.1 (1.4.1) Code Type: X86 (Native) Parent Process: launchd [182] Date/Time: 2010-12-22 22:39:47.833 +0100 OS Version: Mac OS X 10.6.5 (10H574) Report Version: 6 Interval Since Last Report: 257401 sec Crashes Since Last Report: 39 Per-App Interval Since Last Report: 1178959 sec Per-App Crashes Since Last Report: 8 Anonymous UUID: 7CBACDEB-FBAF-4CD5-9C15-7AEA8AC4B5EF Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000000 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 com.apple.HIToolbox 0x99722b6d islGetInputSourceProperty + 1107 1 com.apple.HIToolbox 0x9972262c TSMGetInputSourceProperty + 526 2 com.apple.HIToolbox 0x9972787a _ISSendWindowServerKeyboardLayoutUpdate + 412 3 com.apple.HIToolbox 0x9972622b _TSMSetInputSourceSelected + 1429 4 com.apple.HIToolbox 0x99980209 TSMMessagePortCallBack + 574 5 com.apple.CoreFoundation 0x9226840c __CFMessagePortPerform + 540 6 com.apple.CoreFoundation 0x921d34db __CFRunLoopRun + 6523 7 com.apple.CoreFoundation 0x921d1464 CFRunLoopRunSpecific + 452 8 com.apple.CoreFoundation 0x921d1291 CFRunLoopRunInMode + 97 9 com.apple.HIToolbox 0x99717f58 RunCurrentEventLoopInMode + 392 10 com.apple.HIToolbox 0x99717d0f ReceiveNextEventCommon + 354 11 com.apple.HIToolbox 0x99717b94 BlockUntilNextEventMatchingListInMode + 81 12 com.apple.AppKit 0x9189478d _DPSNextEvent + 847 13 com.apple.AppKit 0x91893fce -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] + 156 14 com.apple.AppKit 0x91856247 -[NSApplication run] + 821 15 com.apple.AppKit 0x9184e2d9 NSApplicationMain + 574 16 com.adiumX.adiumX 0x0000322e 0x1000 + 8750 Thread 1: Dispatch queue: com.apple.libdispatch-manager 0 libSystem.B.dylib 0x968f5982 kevent + 10 1 libSystem.B.dylib 0x968f609c _dispatch_mgr_invoke + 215 2 libSystem.B.dylib 0x968f5559 _dispatch_queue_invoke + 163 3 libSystem.B.dylib 0x968f52fe _dispatch_worker_thread2 + 240 4 libSystem.B.dylib 0x968f4d81 _pthread_wqthread + 390 5 libSystem.B.dylib 0x968f4bc6 start_wqthread + 30 Thread 2: 0 libSystem.B.dylib 0x968f4a12 __workq_kernreturn + 10 1 libSystem.B.dylib 0x968f4fa8 _pthread_wqthread + 941 2 libSystem.B.dylib 0x968f4bc6 start_wqthread + 30 Thread 3: com.apple.CFSocket.private 0 libSystem.B.dylib 0x968ee0c6 select$DARWIN_EXTSN + 10 1 com.apple.CoreFoundation 0x92211c83 __CFSocketManager + 1091 2 libSystem.B.dylib 0x968fc85d _pthread_start + 345 3 libSystem.B.dylib 0x968fc6e2 thread_start + 34 Thread 4: 0 libSystem.B.dylib 0x968f4a12 __workq_kernreturn + 10 1 libSystem.B.dylib 0x968f4fa8 _pthread_wqthread + 941 2 libSystem.B.dylib 0x968f4bc6 start_wqthread + 30 Thread 5: 0 libSystem.B.dylib 0x968cf15a semaphore_timedwait_signal_trap + 10 1 libSystem.B.dylib 0x968fcce5 _pthread_cond_wait + 1066 2 libSystem.B.dylib 0x9692bac8 pthread_cond_timedwait_relative_np + 47 3 ...apple.AddressBook.framework 0x9310043f -[ABRemoteImageLoader workLoop] + 283 4 com.apple.Foundation 0x97822bf0 -[NSThread main] + 45 5 com.apple.Foundation 0x97822ba0 __NSThread__main__ + 1499 6 libSystem.B.dylib 0x968fc85d _pthread_start + 345 7 libSystem.B.dylib 0x968fc6e2 thread_start + 34 Thread 6: 0 libSystem.B.dylib 0x968cf0fa mach_msg_trap + 10 1 libSystem.B.dylib 0x968cf867 mach_msg + 68 2 com.apple.CoreFoundation 0x921d237f __CFRunLoopRun + 2079 3 com.apple.CoreFoundation 0x921d1464 CFRunLoopRunSpecific + 452 4 com.apple.CoreFoundation 0x921d1291 CFRunLoopRunInMode + 97 5 com.apple.Foundation 0x9785b7d0 +[NSURLConnection(NSURLConnectionReallyInternal) _resourceLoadLoop:] + 329 6 com.apple.Foundation 0x97822bf0 -[NSThread main] + 45 7 com.apple.Foundation 0x97822ba0 __NSThread__main__ + 1499 8 libSystem.B.dylib 0x968fc85d _pthread_start + 345 9 libSystem.B.dylib 0x968fc6e2 thread_start + 34 Thread 0 crashed with X86 Thread State (32-bit): eax: 0x00000670 ebx: 0x9972272e ecx: 0x00000000 edx: 0x00000002 edi: 0xa0c3b214 esi: 0x00000004 ebp: 0xbfffe6c8 esp: 0xbfffe660 ss: 0x0000001f efl: 0x00010202 eip: 0x99722b6d cs: 0x00000017 ds: 0x0000001f es: 0x0000001f fs: 0x00000000 gs: 0x00000037 cr2: 0x00000000 Binary Images: 0x1000 - 0x1a0ff7 +com.adiumX.adiumX 1.4.1 (1.4.1) <136586E8-F3F5-99ED-DB1F-48C0027686CB> /Applications/Adium.app/Contents/MacOS/Adium 0x1f9000 - 0x23efe7 +AIUtilities ???

  • Code folding for LaTeX in Emacs

    - by ShreevatsaR
    Is there an Emacs minor-mode (or piece of elisp code) that lets you selectively hide/show environments while in LaTeX mode? For instance, I would like to move to the beginning of a long \begin{figure} block, hit a keystroke, and have the contents of that figure environment hidden from view. Similarly with \begin{proof} and so on, and ideally even with \subsections. Is this possible? I just tried hs-minor-mode, allout-mode, and outline-minor-mode, but most of them don't recognize LaTeX's environments, e.g. hs-minor-mode fails with "scan error: unbalanced parentheses". I would prefer not to have to enter explicit folding marks like {{{ as in folding-mode. [Ideally it would be great if the folding were persistent, but I see that that question doesn't have an accepted answer yet.]

  • Event Capturing vs Event Bubbling

    - by Rajat
    I just wanted to get the general consensus on which is a better mode of event delegation in JS between bubbling and capturing. Now I understand that depending on a particular use-case, one might want to use capturing phase over bubbling or vice versa but I want to understand what delegation mode is preferred for most general cases and why (to me it seems bubbling mode). Or to put it in other words, is there a reason behind W3C addEventListener implementation to favor the bubbling mode. [capturing is initiated only when you specify the 3rd parameter and its true. However, you can forget that 3rd param and bubbling mode is kicked in] I looked up the JQuery's bind function to get an answer to my question and it seems it doesn't even support events in capture phase (it seems to me because of IE not support capturing mode). So looks like bubbling mode is the default choice but why?

  • How to reset ASP.NET MVC client validation mode?

    - by Morten Christiansen
    I'm having a bit of trouble with the client-side validation in the ASP.NET MVC 2 framework and hope someone can help me out. In several situations I find it useful to be able to reset the contents of a form or just a single input element and I need any validation errors to disappear. This in itself is not very hard, and the suggestion provided here works well enough: http://stackoverflow.com/questions/2798427/how-do-i-clear-mvc-client-side-validation-errors-when-a-cancel-button-is-clicked The problem is that, when triggered, client validation goes into an aggressive mode that performs validation on each key press and when an input loses focus. Is there a good way to reset this state as well?

  • How to launch the market intent in 'Give Feedback' mode on android.

    - by Paul Maidment
    Hi There, I have just written a game for the Android market and would like to remind my customers to leave feeback on the market for the application (especially the demo version.) Is there any way to launch the market intent in a mode that will take the user to the feedback / comments section of the page? I already use this approach for linking my demo to the paid app... Intent goToMarket = null; goToMarket = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=com.paulmaidment.games.flagsoftheworld")); startActivity(goToMarket); Is there a best practice that any Android devs out there might know of? Additionally, is there any way to track referalls from my demo app so that I can try to calculate some kind of a conversion rate? (i.e. how effective the demo app is at generating sales.) Thanks, Paul

  • Ad-Hoc mode and Cell (how does it work)?

    - by Ori Cohen
    hello, I am setting up a wireless Ad-Hoc network manually in linux using iwconfig and ifconfig. I have gotten everything working, and I think I understand it all except access point. The part that confused me is this: If I have essid='some_id', channel=11, Mode=Ad-Hoc and appropriate routing/ip on both laptops, why do I need to make sure the Cell is the same? I was under the impression that Ad-Hoc worked independently of the access point. I can easily get around this, I just use iwconfig wlan0 ap 00:00:00:00:00:01 Why is this necessary? I've been unable to find a good tutorial on this. If anyone can clear this up I'd appreciate it. Thanks
