  • how to send text to a process in a shell script?

    - by Martin
    So I have a Linux program that runs in a while(true) loop, which waits for user input, process it and print result to stdout. I want to write a shell script that open this program, feed it lines from a txt file, one line at a time and save the program output for each line to a file. So I want to know if there is any command for: - open a program - send text to a process - receive output from that program Many thanks.

  • AIX Checklist for stable obiee deployment

    - by user554629
    Common AIX configuration issues     ( last updated 27 Aug 2012 ) OBIEE is a complicated system with many moving parts and connection points.The purpose of this article is to provide a checklist to discuss OBIEE deployment with your systems administrators. The information in this article is time sensitive, and updated as I discover new  issues or details. What makes OBIEE different? When Tech Support suggests AIX component upgrades to a stable, locked-down production AIX environment, it is common to get "push back".  "Why is this necessary?  We aren't we seeing issues with other software?"It's a fair question that I have often struggled to answer; here are the talking points: OBIEE is memory intensive.  It is the entire purpose of the software to trade memory for repetitive, more expensive database requests across a network. OBIEE is implemented in C++ and is very dependent on the C++ runtime to behave correctly. OBIEE is aggressively thread efficient;  if atomic operations on a particular architecture do not work correctly, the software crashes. OBIEE dynamically loads third-party database client libraries directly into the nqsserver process.  If the library is not thread-safe, or corrupts process memory the OBIEE crash happens in an unrelated part of the code.  These are extremely difficult bugs to find. OBIEE software uses 99% common source across multiple platforms:  Windows, Linux, AIX, Solaris and HPUX.  If a crash happens on only one platform, we begin to suspect other factors.  load intensity, system differences, configuration choices, hardware failures.  It is rare to have a single product require so many diverse technical skills.   My role in support is to understand system configurations, performance issues, and crashes.   An analyst trained in Business Analytics can't be expected to know AIX internals in the depth required to make configuration choices.  Here are some guidelines. AIX C++ Runtime must be at  version 11.1.0.4$ lslpp -L | grep xlC.aixobiee software will crash if xlC.aix.rte is downlevel;  this is not a "try it" suggestion.Nov 2011 11.1.0.4 version  is appropriate for all AIX versions ( 5, 6, 7 )Download from here:https://www-304.ibm.com/support/docview.wss?uid=swg24031426 No reboot is necessary to install, it can even be installed while applications are using the current version.Restart the apps, and they will pick up the latest version. AIX 5.3 Technology Level 12 is required when running on Power5,6,7 processorsAIX 6.1 was introduced with the newer Power chips, and we have seen no issues with 6.1 or 7.1 versions.Customers with an unstable deployment, dozens of unexplained crashes, became stable after the upgrade.If your AIX system is 5.3, the minimum TL level should be at or higher than this:$ oslevel -s  5300-12-03-1107IBM typically supports only the two latest versions of AIX ( 6.1 and 7.1, for example).  AIX 5.3 is still supported and popular running in an LPAR. obiee userid limits$ ulimit -Ha  ( hard limits )$ ulimit -a   ( default limits )core file size (blocks)     unlimiteddata seg size (kbytes)      unlimitedfile size (blocks)          unlimitedmax memory size (kbytes)    unlimitedopen files                  10240 cpu time (seconds)          unlimitedvirtual memory (kbytes)     unlimitedIt is best to establish the values in /etc/security/limitsroot user is needed to observe and modify this file.If you modify a limit, you will need to relog in to change it again.  For example,$ ulimit -c 0$ ulimit -c 2097151cannot modify limit: Operation not permitted$ ulimit -c unlimited$ ulimit -c0There are only two meaningful values for ulimit -c ; zero or unlimited.Anything else is likely to produce a truncated core file that cannot be analyzed. Deploy 32-bit or 64-bit ?Early versions of OBIEE offered 32-bit or 64-bit choice to AIX customers.The 32-bit choice was needed if a database vendor did not supply a 64-bit client library.That's no longer an issue and beginning with OBIEE 11, 32-bit code is no longer shipped.A common error that leads to "out of memory" conditions to to accept the 32-bit memory configuration choices on 64-bit deployments.  The significant configuration choices are: Maximum process data (heap) size is in an AIX environment variableLDR_CNTRL=IGNOREUNLOAD@LOADPUBLIC@PREREAD_SHLIB@MAXDATA=0x... Two thread stack sizes are made in obiee NQSConfig.INI[ SERVER ]SERVER_THREAD_STACK_SIZE = 0;DB_GATEWAY_THREAD_STACK_SIZE = 0; Sort memory in NQSConfig.INI[ GENERAL ]SORT_MEMORY_SIZE = 4 MB ;SORT_BUFFER_INCREMENT_SIZE = 256 KB ; Choosing a value for MAXDATA:0x080000000  2GB Default maximum 32-bit heap size ( 8 with 7 zeros )0x100000000  4GB 64-bit breaking even with 32-bit ( 1 with 8 zeros )0x200000000  8GB 64-bit double 32-bit max0x400000000 16GB 64-bit safetyUsing 2GB heap size for a 64-bit process will almost certainly lead to an out-of-memory situation.Registers are twice as big ... consume twice as much memory in the heap.Upgrading to a 4GB heap for a 64-bit process is just "breaking even" with 32-bit.A 32-bit process is constrained by the 32-bit virtual addressing limits.  Heap memory is used for dynamic requirements of obiee software, thread stacks for each of the configured threads, and sometimes for shared libraries. 64-bit processes are not constrained in this way;  extra heap space can be configured for safety against a query that might create a sudden requirement for excessive storage.  If the storage is not available, this query might crash the whole server and disrupt existing users.There is no performance penalty on AIX for configuring more memory than required;  extra memory can be configured for safety.  If there are no other considerations, start with 8GB.Choosing a value for Thread Stack size:zero is the value documented to select an appropriate default for thread stack size.  My preference is to change this to an absolute value, even if you intend to use the documented default;  it provides better documentation and removes the "surprise" factor.There are two thread types that can be configured. GATEWAY is used by a thread pool to call a database client library to establish a DB connection.The default size is 256KB;  many customers raise this to 512KB ( no performance penalty for over-configuring ). This value must be set to 1 MB if Teradata connections are used. SERVER threads are used to run queries.  OBIEE uses recursive algorithms during the analysis of query structures which can consume significant thread stack storage.  It's difficult to provide guidance on a value that depends on data and complexity.  The general notion is to provide more space than you think you need,  "double down" and increase the value if you run out, otherwise inspect the query to understand why it is too complex for the thread stack.  There are protections built into the software to abort a single user query that is too complex, but the algorithms don't cover all situations.256 KB  The default 32-bit stack size.  Many customers increased this to 512KB on 32-bit.  A 64-bit server is very likely to crash with this value;  the stack contains mostly register values, which are twice as big.512 KB  The documented 64-bit default.  Some early releases of obiee didn't set this correctly, resulting in 256KB stacks.1 MB  The recommended 64-bit setting.  If your system only ever uses 512KB of stack space, there is no performance penalty for using 1MB stack size.2 MB  Many large customers use this value for safety.  No performance penalty.nqscheduler does not use the NQSConfig.INI file to set thread stack size.If this process crashes because the thread stack is too small, use this to set 2MB:export OBI_BACKGROUND_STACK_SIZE=2048 Shared libraries are not (shared) When application libraries are loaded at run-time, AIX makes a decision on whether to load the libraries in a "public" memory segment.  If the filesystem library permissions do not have the "Read-Other" permission bit, AIX loads the library into private process memory with two significant side-effects:* The libraries reduce the heap storage available.      Might be significant in 32-bit processes;  irrelevant in 64-bit processes.* Library code is loaded into multiple real pages for execution;  one copy for each process.Multiple execution images is a significant issue for both 32- and 64-bit processes.The "real memory pages" saved by using public memory segments is a minor concern.  Today's machines typically have plenty of real memory.The real problem with private copies of libraries is that they consume processor cache blocks, which are limited.   The same library instructions executing in different real pages will cause memory delays as the i-cache ( instruction cache 128KB blocks) are refreshed from real memory.   Performance loss because instructions are delayed is something that is difficult to measure without access to low-level cache fault data.   The machine just appears to be running slowly for no observable reason.This is an easy problem to detect, and an easy problem to correct.Detection:  "genld -l" AIX command produces a list of the libraries used by each process and the AIX memory address where they are loaded.32-bit public segment is 13 ( "dxxxxxxx" ).   private segments are 2-a.64-bit public segment is 9 ( "9xxxxxxxxxxxxxxx") ; private segment is 8.genld -l | grep -v ' d| 9' | sort +2provides a list of privately loaded libraries. Repair: chmod o+r <libname>AIX shared libraries will have a suffix of ".so" or ".a".Another technique is to change all libraries in a selected directory to repair those that might not be currently loaded.   The usual directories that need repair are obiee code, httpd code and plugins, database client libraries and java.chmod o+r /shr/dir/*.a /shr/dir/*.so Configure your system for diagnosticsProduction systems shouldn't crash, and yet bad things happen to good software.If obiee software crashes and produces a core, you should configure your system for reliable transfer of the failing conditions to Oracle Tech Support.  Here's what we need to be able to diagnose a core file from your system.* fullcore enabled. chdev -lsys0 -a fullcore=true* core naming enabled. chcore -n on -d* ulimit must not truncate core. see item 3.* pstack.sh is used to capture core documentation.* obidoc is used to capture current AIX configuration.* snapcore  AIX utility captures core and libraries. Use the proper syntax. $ snapcore -r corename executable-fullpath   /tmp/snapcore will contain the .pax.Z output file.  It is compressed.* If cores are directed to a common directory, ensure obiee userid can write to the directory.  ( chcore -p /cores -d ; chmod 777 /cores )The filesystem must have sufficient space to hold a crashing obiee application.Use:  df -k  Check the "Free" column ( not "% Used" )  8388608 is 8GB. Disable Oracle Client Library signal handlingThe Oracle DB Client Library is frequently distributed with the sqlplus development kit.By default, the library enables a signal handler, which will document a call stack if the application crashes.   The signal handler is not needed, and definitely disruptive to obiee diagnostics.   It needs to be disabled.   sqlnet.ora is typically located at:   $ORACLE_HOME/network/admin/sqlnet.oraAdd this line at the top of the file:   DIAG_SIGHANDLER_ENABLED=FALSE Disable async query in the RPD connection pool.This might be an obiee 10.1.3.4 issue only ( still checking  )."async query" must be disabled in the connection pools.It was designed to enable query cancellation to a database, and turned out to have too many edge conditions in normal communication that produced random corruption of data and crashes.  Please ensure it is turned off in the RPD. Check AIX error report (errpt).Errors external to obiee applications can trigger crashes.  $ /bin/errpt -aHardware errors ( firmware, adapters, disks ) should be reported to IBM support.All application core files are recorded by AIX;  the most recent ones are listed first.

  • My java program seems to be skipping over the try{}, executing the catch{} and then throwing a NullPointerException. What should I do?

    - by Matt Bolopue
    I am writing a program that calculates the number of words, syllables, and sentences in any given text file. I don't need help finding those numbers, however my program (which currently should only find the number of words in the text file) will not import the text file even when I type in the name of the file correctly. The text file is in the same folder as the source code. Instead it tells me every time that what I typed in has the wrong file extension (see my catch{}) and then proceeds to throw a null pointer. I am at a loss for what could be causing it. Any suggestions? import java.io.*; import java.util.*; public class Reading_Lvl_Calc { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub int words = 0; String fileName; Scanner scan; Scanner keyread = new Scanner(System.in); System.out.println("Please enter a file name (or QUIT to exit)"); fileName = keyread.nextLine(); File doc = new File(fileName); //while(scan.equals(null)){ try { scan = new Scanner(doc); } catch(Exception e) { if(fileName.substring(fileName.indexOf(".")) != ".txt") System.out.println("I'm sorry, the file \"" + fileName + "\" has an invalid file extension."); else System.out.println("I am sorry, the file \"" + fileName + " \" cannot be found.\n The file must be in the same directory as this program"); scan = null; } // } while(scan.hasNext()){ words++; scan.next(); } System.out.println(words); } }

  • A Basic Thread

    - by Joe Mayo
    Most of the programs written are single-threaded, meaning that they run on the main execution thread. For various reasons such as performance, scalability, and/or responsiveness additional threads can be useful. .NET has extensive threading support, from the basic threads introduced in v1.0 to the Task Parallel Library (TPL) introduced in v4.0. To get started with threads, it's helpful to begin with the basics; starting a Thread. Why Do I Care? The scenario I'll use for needing to use a thread is writing to a file.  Sometimes, writing to a file takes a while and you don't want your user interface to lock up until the file write is done. In other words, you want the application to be responsive to the user. How Would I Go About It? The solution is to launch a new thread that performs the file write, allowing the main thread to return to the user right away.  Whenever the file writing thread completes, it will let the user know.  In the meantime, the user is free to interact with the program for other tasks. The following examples demonstrate how to do this. Show Me the Code? The code we'll use to work with threads is in the System.Threading namespace, so you'll need the following using directive at the top of the file: using System.Threading; When you run code on a thread, the code is specified via a method.  Here's the code that will execute on the thread: private static void WriteFile() { Thread.Sleep(1000); Console.WriteLine("File Written."); } The call to Thread.Sleep(1000) delays thread execution. The parameter is specified in milliseconds, and 1000 means that this will cause the program to sleep for approximately 1 second.  This method happens to be static, but that's just part of this example, which you'll see is launched from the static Main method.  A thread could be instance or static.  Notice that the method does not have parameters and does not have a return type. As you know, the way to refer to a method is via a delegate.  There is a delegate named ThreadStart in System.Threading that refers to a method without parameters or return type, shown below: ThreadStart fileWriterHandlerDelegate = new ThreadStart(WriteFile); I'll show you the whole program below, but the ThreadStart instance above goes in the Main method. The thread uses the ThreadStart instance, fileWriterHandlerDelegate, to specify the method to execute on the thread: Thread fileWriter = new Thread(fileWriterHandlerDelegate); As shown above, the argument type for the Thread constructor is the ThreadStart delegate type. The fileWriterHandlerDelegate argument is an instance of the ThreadStart delegate type. This creates an instance of a thread and what code will execute, but the new thread instance, fileWriter, isn't running yet. You have to explicitly start it, like this: fileWriter.Start(); Now, the code in the WriteFile method is executing on a separate thread. Meanwhile, the main thread that started the fileWriter thread continues on it's own.  You have two threads running at the same time. Okay, I'm Starting to Get Glassy Eyed. How Does it All Fit Together? The example below is the whole program, pulling all the previous bits together. It's followed by its output and an explanation. using System; using System.Threading; namespace BasicThread { class Program { static void Main() { ThreadStart fileWriterHandlerDelegate = new ThreadStart(WriteFile); Thread fileWriter = new Thread(fileWriterHandlerDelegate); Console.WriteLine("Starting FileWriter"); fileWriter.Start(); Console.WriteLine("Called FileWriter"); Console.ReadKey(); } private static void WriteFile() { Thread.Sleep(1000); Console.WriteLine("File Written"); } } } And here's the output: Starting FileWriter Called FileWriter File Written So, Why are the Printouts Backwards? The output above corresponds to Console.Writeline statements in the program, with the second and third seemingly reversed. In a single-threaded program, "File Written" would print before "Called FileWriter". However, this is a multi-threaded (2 or more threads) program.  In multi-threading, you can't make any assumptions about when a given thread will run.  In this case, I added the Sleep statement to the WriteFile method to greatly increase the chances that the message from the main thread will print first. Without the Thread.Sleep, you could run this on a system with multiple cores and/or multiple processors and potentially get different results each time. Interesting Tangent but What Should I Get Out of All This? Going back to the main point, launching the WriteFile method on a separate thread made the program more responsive.  The file writing logic ran for a while, but the main thread returned to the user, as demonstrated by the print out of "Called FileWriter".  When the file write finished, it let the user know via another print statement. This was a very efficient use of CPU resources that made for a more pleasant user experience. Joe

  • iphone - How do I add videos to iPad simulator?

    - by Mike
    No, dropping the videos to ~/Library/Application Support/iPhone Simulator/3.2/Media/DCIM/100APPLE does not work totally, because the simulator can see the video on Photos.app, but when I try to pick a video using UIImagePickerController my application crashes. I think this may have some relation to the format the video has to have. I am using QuickTime to generate the video. I am using the settings "for iPhone"... so it is generating a M4V with 480x360 pixels H264. I have tried to create a MOV with the same characteristics and one with 640x480 but nothing works. I have also dropped a movie created with iPhone 3GS and it still crashes. this is the error I see when it crashes * Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (1) beyond bounds (0)' the method didFinishPickingMediaWithInfo is never called, so its some issue on the simulator or on the video. The app crashes as soon as I pick the video. any ideas? thanks.

    - by SolidSnake4444
    I saw the other question here with the similar error yet their fixes did not help. I have a jailbroken iphone 3.1.2, and I just purchased apple's $99 dollar thing and I'm trying to make it so I can debug my apps on the phone. The device installs but will not run when clicked build and go. If I click on the icon made on the iphone it works. Any ideas? I already uninstalled and reinstalled my provisioning profile.

  • If I build a solution in C#, how do I add a database to the final program?

    - by DevX
    Apologies if this is a very basic question, but I am preparing to create an executable for a Visual Studio C# Application. (My first time!) My application uses a database that I'm currently storing in SQL Server. This works fine while I'm coding since I created the database manually on my computer. I see that VS2008 has created an .exe in my bin/debug folder, but how do I ensure that any new users (that doesn't already have the database) doing a fresh install gets the database also?

  • One row is skipped each time the program scans a matrix from file !

    - by ZaZu
    Hello there, I had this code working yesterday, but it seems like I edited it a bit and lost the working version. I cant get this to work anymore. I basically want to scan a matrix from a .txt file. But each time it scans the first row, the second one is skipped, and it reads the third instead :( Here is my code : for(i=0;i<=test->rowmat1;i++){ for(j=0;j<=test->colmat1;j++){ fscanf(fin,"%f\t",&test->mat[i][j]); } fscanf(fin,"%*[^\n]",&test->mat[i][j]); } For example, for a matrix of : 1.00 2.00 3.00 4.00 5.00 6.00 7.00 8.00 9.00 10.00 11.00 12.00 If I extract 3 rows and 3 cols, I get : 1.00 2.00 3.00 7.00 8.00 9.00 Then fails, it wants to skip over the second line but there is nothing after 10 11 12 Why did it stop working ? What do I have wrong ? Please help, Thanks in advance.

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!

  • iPad receiving memory warning with low memory use

    - by Fer
    I have an UIWebKit with a HTML, this HTML have several images and text, but just displaying it gives me the memory warning. So I did some tests: The same HTML with different images, fullsize, and after the same images but reduced 50% from it's original size, for the 50% reduced images, I went to preview and reduced all images in 50% The surprising part is the 50% test, you can see that even with 16 images, the memory peak is 4.90MB. That's really surprising. Notice that these values are not always the same, they change but there's not a huge difference between the tests. In the 50% issue, in the 8 and 16 images, although the memory is low, sometimes a memory warning appears, but the performance enhance is noticeable compared to the full size images standing still = memory after scrolling all article 1 Image = [standing still 5MB] [rotating 5.6MB] 2 Images = [standing still 6.99MB] [rotating 7.7MB] 3 Images = [standing still 9.04MB] [rotating 10.9MB] 4 Images = [standing still 10.89MB] [rotating 13.20MB] 8 Images = [standing still 23.14MB] [rotating 25.20MB] (sometimes crashes) 16 Images = [standing still 27.14MB and app crashes] 50% 1 Image = [standing still 3.2MB] [rotating 3.67MB] 2 Image = [standing still 3.2MB] [rotating 3.70MB] 3 Image = [standing still 3.3MB] [rotating 3.79MB] 4 Image = [standing still 3.3MB] [rotating 3.80MB] 8 Images = [standing still 4.29MB] [rotating 4,63MB] (sometimes crashes) 16 Images = [standing still 4.79MB] [rotating 4,90MB] (sometimes crashes) My question is: The app sometimes crashed with 16 small images. Why? The memory was much lower. What is the limit of memory use? These numbers are helpful if you also tell us the maximum. But, the maximum seemed different with the 50% size images. 13.2MB works for large images and 3.8 for small images. Anything higher sometimes crashes. That makes no sense.

  • Is there a good tutorial for figuring out what a website is doing so your program can do the same th

    - by brian d foy
    Is there a good guide or tutorial for people who need to programmatically interact with dynamic websites? There's been a rash of Perl questions about that lately, and I haven't found a good resource to point people toward. I'm asking not because I need one but because I don't want to waste my time writing it if it already exists. Although I'm most interested in Perl, the extra tools and techniques are mostly the same. Typically, I see see these problems in people's questions: Handling, setting, and saving cookies Finding and interacting with forms Handling JavaScript inside your user-agent especially things like onLoad, onSumbit, and Ajax Using HTTP sniffer tools Using Web developer plugins in interactive browsers Interacting with DOM, screen scraping, etc. If there's no good tutorial, I'll add it to my list of things to do (unless someone else wants to do it :). Along the way, if you don't have a suggestion for an existing tutorial, please suggest the things that you think should be in a new one, including links, your favorite tools, and your own user-agent development experiences. I don't care about the particular language you use.
