  • what does this attempted trojan horse code do?

    - by bstullkid
    It looks like this just sends a ping, but whats the point of that when you can just use ping? /* WARNING: this is someone's attempt at writing a malware trojan.

  • libtool failed with exit code 1 on XCode 4.3

    - by Doz
    I have XCode 4.3 and I am getting this frustrating xml-lib related error. I have a feeling its because of the fact that 4.3 is not using /Developer folder but instead the /Applications/XCode.app/... The error message is below: Libtool /Users/dkatz/Library/Developer/Xcode/DerivedData/RWEngines-ewchevfhokeivnffrputdqapsyxu/Build/Products/Release-iphonesimulator/RWEngines.framework/Versions/A/RWEngines normal i386 cd /Users/dkatz/Sites/xCode/RWA/RWEngines setenv MACOSX_DEPLOYMENT_TARGET 10.6 setenv PATH "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool -static -arch_only i386 -syslibroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk -L/Users/dkatz/Library/Developer/Xcode/DerivedData/RWEngines-ewchevfhokeivnffrputdqapsyxu/Build/Products/Release-iphonesimulator -filelist /Users/dkatz/Library/Developer/Xcode/DerivedData/RWEngines-ewchevfhokeivnffrputdqapsyxu/Build/Intermediates/RWEngines.build/Release-iphonesimulator/RWEngines.build/Objects-normal/i386/RWEngines.LinkFileList -ObjC -Xlinker -no_implicit_dylibs -D__IPHONE_OS_VERSION_MIN_REQUIRED=50000 -framework UIKit /Users/dkatz/Library/Developer/Xcode/DerivedData/RWEngines-ewchevfhokeivnffrputdqapsyxu/Build/Products/Release-iphonesimulator/libCorePlot-CocoaTouch.a -framework SenTestingKit -framework QuartzCore -framework Foundation -framework RWCommon -o /Users/dkatz/Library/Developer/Xcode/DerivedData/RWEngines-ewchevfhokeivnffrputdqapsyxu/Build/Products/Release-iphonesimulator/RWEngines.framework/Versions/A/RWEngines And the actual error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool failed with exit code 1 Thanks guys!

  • Generate markdown from source code doc-comments

    - by erikkallen
    Is there any easy way to generate markdown from source code comments? I'm looking for something similar to Sandcastle, but with Markdown (or something like it) as output. The full story is that I use DokuWiki to generate documentation. It has many nice properties, including that all its data is stored in text files. So my idea is that I should somehow be able to get my API docs into the same place as the rest of my documentation. So far my best bet seems to be to write a custom documenter for NDoc3, but perhaps someone has already done something similar which would save me the trouble. I realize I might need to tweak it a little due to slight syntax differences.

  • Mapping enum with fluent nhibernate

    - by Puneet
    I am following the http://wiki.fluentnhibernate.org/Getting%5Fstarted tutorial to create my first NHibernate project with Fluent NHibernate I have 2 tables 1) Account with fields Id AccountHolderName AccountTypeId 2) AccountType with fields Id AccountTypeName Right now the account types can be Savings or Current So the table AccountTypes stores 2 rows 1 - Savings 2 - Current For AccoutType table I have defined enum public enum AccountType { Savings=1, Current=2 } For Account table I define the entity class public class Account { public virtual int Id {get; private set;} public virtual string AccountHolderName {get; set;} public virtual string AccountType {get; set;} } The fluent nhibernate mappings are: public AgencyMap() { Id(o => o.Id); Map(o => o.AccountHolderName); Map(o => o.AccountType); } When I try to run the solution, it gives an exception - InnerException = {"(XmlDocument)(2,4): XML validation error: The element 'class' in namespace 'urn:nhibernate-mapping-2.2' has incomplete content. List of possible elements expected: 'meta, subselect, cache, synchronize, comment, tuplizer, id, composite-id' in namespace 'ur... I guess that is because I have not speciofied any mapping for AccountType. The questions are: How can I use AccountType enum instead of a AccountType class? Maybe I am going on wrong track. Is there a better way to do this? Thanks!

  • Creating an array & outputting its code definition for preloading

    - by user422318
    I want to create a 2d array that represents my 2d canvas. For each pixel, I will look up the value and then save an integer {0, 1, 2, 3, 4} as each element of the array. Unfortunately, this takes way too friggin' long to run each time I load the game. How can I write a script that creates this array for me and outputs the array code so I can just paste it in a js file and have it preloaded? (I'm prototyping a game, so I just need to run this for my test map or two.)

  • How do I get callgrind to dump source line information?

    - by Jeremybub
    I'm trying to profile a shared library on GNU/Linux which does real-time audio processing, so performance is important. I run another program which hooks it up to the audio input and output of my system, and profile that with callgrind. Looking at the results in KCacheGrind, I get great information about what functions are taking up most of my time. However, it won't let me look at the line by line information, and instead says I need to compile it with debugging symbols and run the profiling again. The program which I am profiling is not compiled with debug symbols, but the library is. And I know this, because interestingly, source code annotations for cachegrind work fine. When I run callgrind, it says the default is to dump source line information, but it just isn't doing that. Is there some way I could force it to, or figure out what's stopping it?

  • Optimize C# Code Fragment

    - by Eric J.
    I'm profiling some C# code. The method below is one of the most expensive ones. For the purpose of this question, assume that micro-optimization is the right thing to do. Is there an approach to improve performance of this method? Changing the input parameter to p to ulong[] would create a macro inefficiency. static ulong Fetch64(byte[] p, int ofs = 0) { unchecked { ulong result = p[0 + ofs] + ((ulong)p[1 + ofs] << 8) + ((ulong)p[2 + ofs] << 16) + ((ulong)p[3 + ofs] << 24) + ((ulong)p[4 + ofs] << 32) + ((ulong)p[5 + ofs] << 40) + ((ulong)p[6 + ofs] << 48) + ((ulong)p[7 + ofs] << 56); return result; } }

  • Should I catch exceptions thrown when closing java.sql.Connection

    - by jb
    Connection.close() may throw SqlException, but I have always assumed that it is safe to ignore any such exceptions (and I have never seen code that does not ignore them). Normally I would write: try{ connection.close(); }catch(Exception e) {} Or try{ connection.close(); }catch(Exception e) { logger.log(e.getMessage(), e); } The question is: Is it bad practice (and has anyone had problems when ignoring such exeptions). When Connection.close() does throw any exception. If it is bad how should I handle the exception. Comment: I know that discarding exceptions is evil, but I'm reffering only to exceptions thrown when closing a connection (and as I've seen this is fairly common in this case). Does anyone know when Connection.close() may throw anything?

  • iphone: accessing the preferences localization file from code

    - by phonecoddy
    I was just facing the following problem and couldn't find a solution for it. Hopefully someone could help. The app I am working on has some preferences, which are using a localization file. Now I want to use labels in my app, which display the exact names, which are used in the localization file for the preferences. But I couldn't find a way to access the information which is stored in Settings.bundle - en.lproj - localizationfile.strings. to make this clear: If you open your preferences for your app, the display shows the localized string of the title and the value of the setting. I need to access the localized string of the title of each preference from my code. Does any know how to do this?

  • Running NUnit Tests from Code

    - by Dror Helper
    I'm trying to write a simple method that receives a file an runs it using NUnit. The code I managed to build using NUnit's source does not work: if(openFileDialog1.ShowDialog() != DialogResult.OK) { return; } var builder = new TestSuiteBuilder(); var testPackage = new TestPackage(openFileDialog1.FileName); var directoryName = Path.GetDirectoryName(openFileDialog1.FileName); testPackage.BasePath = directoryName; var suite = builder.Build(testPackage); TestResult result = suite.Run(new NullListener(), TestFilter.Empty); The problem is that I keep getting an exception thrown by builder.Build stating that the assembly was not found. What am I missing?

  • What is "src" directory created by Eclipse?

    - by Roman
    I just installed Eclipse. The Eclipse created the "workspace" folder. In this folder I created a "game" sub-folder (for my class called "game"). I have already .java files for that project (I wrote them in a text editor before I started to use Eclipse). I put all my .java file into the "game" directory. In Eclipse I created a "New Java Project" from existing code. What wanders me is that the Eclipse create a "src" sub-folder into my "game" folder. As far as I understand "src" stands for "source". But my source (.java files) is in the "game" (by the construction). Am I doing something wrong?

  • PHP code not working on IE

    - by Michael Frey
    I have a website with a flag. If it is clicked, the language of the website changes. Here is the code displaying the flag, which is a form with post event: <?php $pagename = $_SERVER['REQUEST_URI']; echo '<form action="'.$pagename.'" method="post"> <input name="formlanguage" type="image" '; if ($_SESSION['lang'] == 0) { echo 'alt="English" src="images/en.png" value="1" '; } else { echo 'alt="Deutsch" src="images/de.png" value="0" '; } echo '/></form>'; ?> Here is the response to that, and this part always fails on IE: if (isset($_POST['formlanguage'])) { $_SESSION['lang']=$_POST['formlanguage']; } I can not figure out why it works on Chrome but not IE. I assume that it might be a setting of IE. But what could that be?

  • Help me to refactor this F# code to tail recursion

    - by Kev
    I write some code to learning F#. Here is a example: let nextPrime list= let rec loop n= match n with | _ when (list |> List.filter (fun x -> x <= ( n |> double |> sqrt |> int)) |> List.forall (fun x -> n % x <> 0)) -> n | _ -> loop (n+1) loop (List.max list + 1) let rec findPrimes num= match num with | 1 -> [2] | n -> let temp = findPrimes <| n-1 (nextPrime temp ) :: temp //find 10 primes findPrimes 10 |> printfn "%A" I'm very happy that it just works! I'm totally beginner to recursion Recursion is a wonderful thing. I think findPrimes is not efficient. Someone help me to refactor findPrimes to tail recursion if possible? BTW, is there some more efficient way to find first n primes?

  • Visual Studio: What approach do you use to 'template' plumbing for similiar projects?

    - by Sosh
    When building ASP.NET projects there is a certain amount of boilerplate, or plumbing that needs to be done, which is often identical across projects. This is especially the case with MVC and ALT.NET approaches. [I'm thinking of things such as: IoC, ORM, Solution structure (projects), Session Management, User Management, I18n etc.] I would like to know what approach you find best for 'reusing' this plumbing accross projects? Have a 'master solution' which you duplicate and rename somehow? (I'm using a this to a degree at the moment, but it's fairly messy. Would be interested how people do this 'better') Mainly rely on Shared Library projects? (I find this appropriate for some things, but too restrictive for things that have to be customised) Code generation tools, such as T4? (Similar to the approach used by SharpArchitecture - have not tried this myself) Something else? Thanks for sharing your experiences!

  • Enable Query Strings in Code Igniter

    - by tarnfeld
    Hey, I am trying to implement Twitter's OAuth into my Code Igniter web application at which the callback URL is /auth/ so once you have authenticated with Twitter you are taken to /auth/?oauth_token=SOME-TOKEN. I want to keep the nice clean URL's the framework provides using the /controller/method/ style of URL but I want to enable query strings as well, there will only ever be one name of the data oauth_token so it's ok if it has to be hard coded. Any ideas? I have tried tons of the things people are saying to do, but none work :( PS: I'm using the .htaccess method of URL rewriting.

  • Its all working so now I can chill

    - by bizl
    Most software houses I have been at have this attitude about their work. Get it done quick and move on. For programmers I find that the chill time is time that can be used to either improve infrastructure, refactor some old code or learn a new language. I would like to know what your throughts about 'chill time' if its the right attitude at all, and if so what to do with it. Is this sort of chilling helpful for a programmer, what are things you do with your own chill time if you adopt this approach to work.

  • How to write in an file in MSIL code

    Hi all, I have a aspx webpage which uses an assembly mine (which mades a custom authentification). I would like to modify MSIL code (so just with ILDASM/ILASM tools) of my assembly in order to log something in a file. I have tried to add this at the end of the authentification method of my assembly : IL_0034: ldstr "C:\\path_to_my_website\\log.txt" IL_0039: newobj instance void [mscorlib]System.IO.StreamWriter::.ctor(string) IL_003e: stloc.1 IL_003f: ldloc.1 IL_0040: ldstr "test" IL_0045: callvirt instance void [mscorlib]System.IO.TextWriter::Write(string) IL_004a: nop IL_004b: ldloc.1 IL_004c: callvirt instance void [mscorlib]System.IO.TextWriter::Close() IL_0051: nop ILASM does not find any error, and the CLR does not throw any exception at runtime, but the file is not created or modified ! :( Any idea ?
