• Best practice- handling images on website

  - by Steve

  I am porting an old eCommerce site to MVC 3 and would like to take advantage of design improvements. The site currently has product images stored in 3 sizes: thumbnail, medium (for display in a list) and expanded for a zoomed look. Right now we are having to upload 3 separate images that are sized exactly right, provide 3 different names that match what the site expects, etc., it is a pain. I'd like to upload just 1 file, the large one, then let the site reduce it to needed sizes, and I'd like the flexibility to change the thumbnail and list sizes depending on user preferences, form factor (e.g. mobile, iPad, desktop), etc. so might need many copies of the same image. My question is should the image be reduced then saved several times upon upload and if so what is a good storage/naming convention? The other idea is to store just the single image but resize it programmatically before serving it to the client. Has anybody done this and what are the tradeoffs besides a few more machine cycles? How do you pass a temporary image in memory to the client (there is no URL)?

• Handling large integers in python [migrated]

  - by Sushma Palimar

  I had written a program in python to find b such that a prime number p divides b^2-8. The range for b is [1, (p+1)/2]. For small integers it works, say only up to 7 digits. But not for large integers, say for p = 140737471578113. I get the error message for i in range (2,p1,1): MemoryError I wrote the program as #!/usr/bin/python3 p=long(raw_input('enter the prime number:')) p1=long((p+1)/2) for i in range (2,p1,1): s = long((i*i)-8) if (s%p==0): print i

• Difference between '\n' and '\r\n'

  - by sukhbir

  Yes yes, I am aware that '\n' writes a newline in UNIX while for Windows there is the two character sequence: '\r\n'. All this is very nice in theory, but my question is why? Why the carriage return character is extra in Windows? If UNIX can do it in \n why does it take Windows two characters to do this? I am reading David Beazley's Python book and he says: For example, on Windows, writing the character '\n' actually outputs the two- character sequence '\r\n' (and when reading the file back, '\r\n' is translated back into a single '\n' character). Why the extra effort? I will be honest. I have known the difference for a long time but have never bothered to ask WHY. I hope that is answered today. Thanks for your time.

• Basic SDL2 Code which "Stop working" when calling SDL_Quit() [migrated]

  - by Rivten

  So I got into SDL2 with C++ quite recently and I did this very simple code : int main(int argc, char** argv) { SDL_Event *event; bool done = false; if(SDL_Init(SDL_INIT_VIDEO) != 0) { std::cerr << "Problèmes pour initialiser la SDL : " << SDL_GetError() << std::endl; return 1; } SDL_Window *window = 0; window = SDL_CreateWindow("Mopion", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WIDTH, HEIGHT, SDL_WINDOW_SHOWN); if(window == 0) { done = true; } while(!done) { while(SDL_PollEvent(event)) { switch(event->type) { case SDL_QUIT: done = true; break; case SDL_KEYUP: if(event->key.keysym.sym == SDLK_q) { done = true; } break; default: break; } } } SDL_DestroyWindow(window); SDL_Quit(); return 0; } While that code executes at first quite well, when I hit the "Q" key, the window closes but I got a Windows Error Window saying that "My program stopped working." which is not very convenient. Using the debugger, I found that everything is fine until SDL_Quit() is called. Anyone has any idea why this is going on ? Thanks a lot !

• What is the best practice for reading a large number of custom settings from a text file?

  - by jawilmont

  So I have been looking through some code I wrote a few years ago for an economic simulation program. Each simulation has a large number of settings that can be saved to a file and later loaded back into the program to re-run the same/similar simulation. Some of the settings are optional or depend on what is being simulated. The code to read back the parameters is basically one very large switch statement (with a few nested switch statements). I was wondering if there is a better way to handle this situation. One line of the settings file might look like this: #RA:1,MT:DiscriminatoryPriceKDoubleAuction,OF:Demo Output.csv,QM:100,NT:5000,KP:0.5 //continues... And some of the code that would read that line: switch( Character.toUpperCase( s.charAt(0) ) ) { case 'R': randSeed = Integer.valueOf( s.substring(3).trim() ); break; case 'M': marketType = s.substring(3).trim(); System.err.println("MarketType: " + marketType); break; case 'O': outputFileName = s.substring(3).trim() ; break; case 'Q': quantityOfMarkets = Integer.valueOf( s.substring(3).trim() ); break; case 'N': maxTradesPerRound = Integer.valueOf( s.substring(3).trim() ); break; case 'K': kParameter = Float.valueOf( s.substring(3).trim() ); break; // continues... }

• Key Handling mechanics

  - by Max

  I am new to game development and am working on my first game using OpenGL and C++. I have a game class which handles everything necessary in an update() function. Now i want to handle keyboard inputs. I use GLFW which supports key callbacks. However i wonder how to deal with inputs. Should i record the keys pressed and poll on it the next time my game updates or should the callback immediately perform the necessary actions? And why? Thanks :)

• What's the reason in your mind Exception are heavily used in Managed (C# and Java) language but not in C++?

  - by ZijingWu

  AFAIK, a lot of C++ projects don't allow exceptions and deny them in coding guidelines. I have a lot of reasons, for example, Exception is hard to handle correctly if your binary needs to be compiled by separate and different compilers. But it doesn't fully convince me, there is a lot of projects which are just using one compiler. Compared to C++, Exceptions are heavily used in C# and Java and the reason can only be that Exception are not bringing enough benefit. One point is Debugbility in practice. Exception can not get the call stack in C++ code, but in C# and Java you can get the call stack from Exception, it is significant and makes debugging easier. No-CallStack is not the fault of the Exception, it is the language difference , but it impacts the Exception usage. So what's the reason that exceptions are frowned upon in c++ programs?

• Handling timeout in network application

  - by user2175831

  How can I handle timeouts in a network application. I'm implementing a provisioning system on a Linux server, the code is huge so I'm going to put the algorithm, it works as like this Read provisioning commands from file Send it to another server using TCP Save the request in hash. Receive the response then if successful response received then remove request from hash if failed response received then retry the message The problem I'm in now is when the program didn't receive the response for a timeout reason then the request will be waiting for a response forever and won't be retried. And please note that I'll be sending hundreds of commands and I have to monitor the timeout commands for all of them. I tried to use timer but that didn't help because I'll end up with so many waiting timers and I'm not sure if this is a good way of doing this. The question is how can I save the message in some data structure and check to remove or retry it later when there is no response from the other end? Please note that I'm willing to change the algorithm to anything you suggest that could deal with the timeouts.

• When should I decline to make a requested change?

  - by reuscam

  I work on the software side of a company that provides custom hardware with software running on top of it. Often times the hardware is not engineered well. In those cases, I am often asked first to troubleshoot the problem - of course the symptom is always "your software crashed" or something along those lines. Just recently we had another one of these incidents where power on a USB line is not reliable, and it causes a USB device to fail. This causes a usability problem in one of our applications. I have been asked by upper management to handle this better - continually monitor the USB device, and if it disappears, then reboot, or try to reset it. Doing either of these is not guaranteed to fix anything. Ultimately, the real fix is to correct the reliability of the device from the hardware side. I could improve performance, but not to 100%, and of course I would be using my already limited time to bloat code and add yet another device monitoring thread. So with all that said, how do I make a good decision about when to say that this needs to be a hardware fix, and only a hardware fix? Can I approach this quantitatively, and come up with some sort of definitive yes/no test? I'm sure its not that easy.

• getting detailed information about structured exceptions

  - by Martin

  My Visual C++ application is compiled with /EHA option, letting me catch structured exceptions (division by zero, access violation, etc). I then translate those exceptions to my own exception class using _set_se_translator(). My goal is to improve our logging of those types of exceptions. I can get the type of exception from the EXCEPTION_RECORD structure, and the exception address. I would like to be able to gather more information, like the source file/location where the exception is thrown, the call stack, etc. Is that possible? I do create an exception minidump on structured exceptions - is there a tool to automatically get the call stack from that?

• UnitTest ExpectedException with multiple Exceptions

  - by masterchris_99

  I want one TestMethod for multiple exceptions. The Problem ist that the Testmethod stops after the first thrown exception. I know that I can do something like that: try { sAbc.ToInteger(); Assert.Fail(); // If it gets to this line, no exception was thrown } catch (ArgumentException) { } But I want to use the following code-base: [TestMethod, ExpectedException(typeof(ArgumentException), "...")] public void StringToIntException() { sAbc.ToInteger(); // throws an exception and stops here sDecimal.ToInteger(); // throws theoretically a exception too... } And I don't want to create one testmethod for each possible exception like that: [TestMethod, ExpectedException(typeof(ArgumentException), "...")] public void StringToIntException() { sAbc.ToInteger(); } [TestMethod, ExpectedException(typeof(ArgumentException), "...")] public void StringToIntException() { sDecimal.ToInteger(); }

• Why is TargetInvocationException treated as uncaught by the IDE?

  - by Jason Coyne

  I have some code that is using reflection to pull property values from an object. In some cases the properties may throw exceptions, because they have null references etc. try { child.Target = propertyInfo.GetValue(target, null); } catch (TargetInvocationException ex) { child.Target = ex.InnerException.Message; } catch (Exception ex) { child.Target = ex.Message; } Ultimately the code works correctly, however when I am running under the debugger : When the property throws an exception, the IDE drops into the debugger as if the exception was uncaught. If I just hit run, the program flows through and the exception comes out as a TargetInvocationException with the real exception in the InnerException property. How can I stop this from happening?

• errorPage directive works, but error-page in web.xml doesn't?

  - by danb

  I get jsp exceptions causing a forward to my error page when I put this at the top of my JSPs... <%@ page errorPage="/error.page" %> but when I try to do it globally with web.xml like so: <error-page> <exception-type>java.lang.Throwable</exception-type> <location>/error.page</location> </error-page> I just get a blank page... I've also tried putting /error.jsp in the location element.. but no love with that either.. I am triggering an exception with a jsp that just contains this: <%if(true)throw new RuntimeException("test exception");%> I do see the exception in the console from tomcat but I just can't get that error page to show without a directive on every jsp... am I missing something simple here?

• @ExceptionHandler doesn't handle the thrown exceptions

  - by Javi

  Hello, I have a method in my controller which will handle the exceptions thrown by the application. So I have a method like this one. @Controller public class ExceptionController { @RequestMapping(value="/error") @ExceptionHandler(value={Exception.class, NullPointerException.class}) public String showError(Exception e, Model model){ return "tiles:error"; } } And to try I if it works I throw a NullPointerException in another method in other method controller: boolean a = true; if(a){ throw new NullPointerException(); } After the exception is thrown it is printed in the JSP, but it doesn't go throw my showError() method (I've set a breakpoint there and it never enters). showError() method will catch the exception and will show different error pages depending on the exception type (though now it always shows the same error page). If I go to the url /error it shows the error page so the showError() method is OK. I'm using Spring 3. What can be the problem? Thanks.

• Unauthorized Access Exception using Web Deploy to Site when the site root is a UNC path

  - by Peter LaComb Jr.

  I am trying to use Web Deploy to deploy a site where the Site is rooted on a UNC path instead of a local drive. This is because I want to have a shared configuration, and have all servers point to the same UNC for content. That would allow me to deploy to one server and have all servers updated at the same time. I've created a share with everyone and users read/write. The NTFS permissions have the ID of the appDomain account as full control, and that is the same account that is configured as the specific user in Management Service Delegation. I can log on to the destination server as that ID, access the share and create/delete files. However, I'm getting the following exception in my Microsoft Web Deploy log on the destination server: User: Client IP: 192.168.62.174 Content-Type: application/msdeploy Version: 9.0.0.0 MSDeploy.VersionMin: 7.1.600.0 MSDeploy.VersionMax: 9.0.1631.0 MSDeploy.Method: Sync MSDeploy.RequestId: c060c823-cdb4-4abe-8294-5ffbdc327d2e MSDeploy.RequestCulture: en-US MSDeploy.RequestUICulture: en-US ServerVersion: 9.0.1631.0 Skip: objectName="^configProtectedData$" Provider: auto, Path: A tracing deployment agent exception occurred that was propagated to the client.

• NSURL URLWithString: raises exception

  - by Stephen Darlington

  In short, [NSURL URLWithString:] appears to be raising an exception. According to the documentation "If the string was malformed, returns nil." There is no mention of an exception being raised under any circumstance. In addition to this, I am both encoding the URL and checking for nil before converting the string to a URL. Can anyone offer any advice as to which exception it could be or what other error checking I should be doing before converting the URL? In case you're interested in the details, the calling code looks like this: NSString* tmpText = [newUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; if (tmpText == nil) { // error handling } else { NSURL* tmpURL = [NSURL URLWithString:tmpText]; And this is a section from the crash report download from iTunes Connect: 8 libobjc.A.dylib 0x300c1f84 objc_exception_throw 9 CoreFoundation 0x3029a598 +[NSException raise:format:arguments:] 10 CoreFoundation 0x3029a538 +[NSException raise:format:] 11 Foundation 0x30696dde -[NSURL initWithString:relativeToURL:] 12 Foundation 0x30696cd8 +[NSURL URLWithString:relativeToURL:] 13 Foundation 0x30696cae +[NSURL URLWithString:] 14 Yummy 0x000146ca -[DeliciousPostCell setUrl:] + 46 It seems that the URL was in a "bad" format somehow but that should really be returning a nil not an exception. I have never seen the exception being raised myself so I can't use XCode to trap the code and see what's happening. And the user(s) that experienced the problem never contacted me directly so I can't ask for more details. Any suggestions greatly appreciated. Update (14/7/2009): Seems like such a hack, but I added an exception block around the suspect line. I also raised a Radar bug report (#7031551) suggesting that the code should match the documentation.

• How to fix security exception when using recaptcha on MVC site

  - by camainc

  I followed this excellent blog post to implement recaptcha on my MVC site: http://devlicio.us/blogs/derik_whittaker/archive/2008/12/02/using-recaptcha-with-asp-net-mvc.aspx I converted the code to VB, and everything seems to compile ok. However, when the code gets to the place where the recapture is about to be generated, I get a security exception. Here is the function where the exception occurs (on the last line in the function): <Extension()> _ Public Function GenerateCaptcha(ByVal htmlHelper As HtmlHelper) As MvcHtmlString Dim captchaControl As New Recaptcha.RecaptchaControl With captchaControl .ID = "recaptcha" .Theme = "blackglass" .PublicKey = "6Lcv9AsAAAAAALCSZNRfWFmrKjw2AR-yuZAL84Bd" .PrivateKey = "6Lcv9AsAAAAAAHCbRujWcZzrY0z6G_HIMvFyYEPR" End With Dim htmlWriter As New HtmlTextWriter(New IO.StringWriter) captchaControl.RenderControl(htmlWriter) Return MvcHtmlString.Create(htmlWriter.InnerWriter.ToString()) End Function The exception is this: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
