  • is this a correct way to generate rsa keys?

    - by calccrypto
    is this code going to give me correct values for RSA keys (assuming that the other functions are correct)? im having trouble getting my program to decrypt properly, as in certain blocks are not decrypting properly this is in python: import random def keygen(bits): p = q = 3 while p == q: p = random.randint(2**(bits/2-2),2**(bits/2)) q = random.randint(2**(bits/2-2),2**(bits/2)) p += not(p&1) # changes the values from q += not(q&1) # even to odd while MillerRabin(p) == False: # checks for primality p -= 2 while MillerRabin(q) == False: q -= 2 n = p * q tot = (p-1) * (q-1) e = tot while gcd(tot,e) != 1: e = random.randint(3,tot-1) d = getd(tot,e) # gets the multiplicative inverse while d<0: # i can probably replace this with mod d = d + tot return e,d,n one set of keys generated: e = 3daf16a37799d3b2c951c9baab30ad2d d = 16873c0dd2825b2e8e6c2c68da3a5e25 n = dc2a732d64b83816a99448a2c2077ced

  • How should I call the operation that limit a string's length?

    - by egarcia
    This is a language-agnostic question - unless you count English as a language. I've got this list of items which can have very long names. For aesthetic purposes, these names must be made shorter in some cases, adding dots (...) to indicate that the name is longer. So for example, if article.name returns this: lorem ipsum dolor sit amet I'd like to get this other output. lorem ipsum dolor ... I can program this quite easily. My question is: how should I call that shortening operation? I mean the name, not the implementation. Is there a standard English name for it?

  • Why calling ISet<dynamic>.Contains() compiles, but throws an exception at runtime?

    - by Andrey Breslav
    Please, help me to explain the following behavior: dynamic d = 1; ISet<dynamic> s = new HashSet<dynamic>(); s.Contains(d); The code compiles with no errors/warnings, but at the last line I get the following exception: Unhandled Exception: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'System.Collections.Generic.ISet<object>' does not contain a definition for 'Contains' at CallSite.Target(Closure , CallSite , ISet`1 , Object ) at System.Dynamic.UpdateDelegates.UpdateAndExecuteVoid2[T0,T1](CallSite site, T0 arg0, T1 arg1) at FormulaToSimulation.Program.Main(String[] args) in As far as I can tell, this is related to dynamic overload resolution, but the strange things are (1) If the type of s is HashSet<dynamic>, no exception occurs. (2) If I use a non-generic interface with a method accepting a dynamic argument, no exception occurs. Thus, it looks like this problem is related particularly with generic interfaces, but I could not find out what exactly causes the problem. Is it a bug in the compiler/typesystem, or legitimate behavior?

  • Issuing native system commands in Scala

    - by Tony
    I want to issue a native system command from a Scala program, and perhaps trap the output. ("ls" comes to mind. There may be other ways to get directory information without issuing the command, but that's beside the point of my question.) It would correspond to os.system(...) in Python. I've looked in "Programming in Scala". I've looked in O'Reilly's "Programming Scala". I've Googled several combinations of terms. No luck yet. Can someone out there give me an example, or point me at a resource where I can find an example?

  • TCP and UDP are using different OS Buffer?

    - by Jack
    HI all. Here is the scenario. I have port 8888 for my program to use. I build a TCP and a UDP listener on that port. (This can do, c# allows, because they are two different protocols) My question is If the network traffic is very busy, TCP sockets may refuse or signalling the other end to stop sending things, it is called congestion control, right? So if TCP is congestion controlling, other ends may not send more data, in this "TCP quiet period", UDP channel should have not that much of traffic, right? I want to figure out the TCP traffic will affect UDP traffic or not?

  • doubt in sizeof implementation

    - by aks
    Below is the program to find the size of a structure without using sizeof operator: struct MyStruct { int i; int j; }; int main() { struct MyStruct *p=0; int size = ((char*)(p+1))-((char*)p); printf("\nSIZE : [%d]\nSIZE : [%d]\n", size); return 0; } My doubt is: Why is typecasting to char * required? If I don't use the char* pointer, the output is 1 - WHY?

  • Software Protection: Shuffeling my application?

    - by Martijn Courteaux
    Hi, I want to continue on my previous question: http://stackoverflow.com/questions/3007168/torrents-can-i-protect-my-software-by-sending-wrong-bytes Developer Art suggested to add a unique key to the application, to identifier the cracker. But JAB said that crackers can search where my unique key is located by checking for binary differences, if the cracker has multiple copies of my software. Then crackers change that key to make them self anonymous. That is true. Now comes the question: If I want to add a unique key, are there tools to shuffle (a kind of obfuscation) the program modules? So, that a binary compare would say that the two files are completely different. So they can't locate the identifier key. I'm pretty sure it is possible (maybe by replacing assembler blocks and make some jumps). I think it would be enough to make 30 to 40 shuffles of my software. Thanks

  • How does compilation work with AOP?

    - by alee
    I need quick answer to a simple thing in AOP. If i have a code deployed at client side and i have written new aspects, which i want in the client side software. do i have to "recompile" complete software with "original" code and new "AOP" code? (with aop compiler)? i.e. do i need the source code of original program with source code of new AOP and compile 'em boht? P.S: I am asking in general, not being specific to any language.

  • Pseudo Transparant images

    - by Samuel
    Hello World! For an assignment at university we program in a pretty unknown language Modula 2, which lacks major graphic support. I was wondering how to achieve a 'transparency' effect on images, i figured it would work like this: Create a 2D array for the background area of the image filled with the colours of the different pixels in that area, create another 2D array of the image with again the colours of every picture and than merge the pixel colours and draw the different "new colours" on their appropriate place. What i was wondering about: how do i merge the colours (hexadecimals) just: ( colour1 + colour2 ) / 2 ? Thanks for your help!!

  • Flash crash on long JSON load time

    - by MooCow
    I have a Flex program that gets a JSON array from a PHP script. The PHP script doesn't contain just a simple JSON array but it grabs data from Activecollab and do some work on the data before encoding the data. The first test involve a small JSON array that took a short time to encode by PHP. However, when I try to scale up the test, the Flash movie will crash trying to load the JSON data from PHP. There's no code difference between the tests, just the amount of data and amount of time it takes PHP to encode. Am I looking at a memory problem or a time out problem?

  • K&R Exercise 1-21 - Mental incomprehension.

    - by asdfg
    The "impossible" K&R exercise. "Write a program entab that replaces strings of blanks by the minimum number of tabs and blanks to achieve the same spacing. Use the same tab stops, say every n columns. Should n be a variable or a symbolic parameter?" The problem I'm having is, I'm unsure about how to even do this correctly. I know it's not very explanatory, but that's pretty much the problem here. Most of the examples I've seen have counted a number of blanks, and replaced those series with a tab, but this isn't what its asking, I reckon I understand what its asking, but currently feel unable to do this. Could anyone help :)

  • All Targets Not Being Called (nested Targets not being executed)

    - by obautista
    I am using a two TARGET files. On one TARGET file I call a TARGET that is inside the second TARGET file. This second TARGET then calls another TARGET that has 6 other TARGET calls, which do a number of different things (in addition to calling other nested TARGETS (but inside the same TARGET file)). The problem is that, on the TARGET where I call 6 TARGETS, only the first one is being executed. The program doesnt find its way to call the 2nd, 3rd, 4th, 5th, and 6th TARGET. Is there a limit to the number of nested TARGETS that can be called and run? Nothing is failing. The problem is the other TARGET calls are not running. Thanks for any help you can provide.

  • MySQL import in phpmyadmin (CSV) chokes on quotes

    - by Andrew Swift
    I am trying to import a .csv file into a MySQL table via phpMyAdmin. The .csv file is separated by pipes, formated like this: data|d'ata|d'a"ta|dat"a| data|"da"ta|data|da't'a| dat'a|data|da"ta"|da'ta| The data contains quotes. I have no control over the format in which I recieve the data -- it is generated by a third party. The problem comes when there is a | followed by a double quote. I always get an "invalid field count in CSV input on line N" error. I am uploading the file from the import page, using Latin1, CSV, terminated by |, separated by ". I would like to just change the "enclosed by" character, but I keep getting "Invalid parameter for CSV import: Fields enclosed by". I have tried various characters with no success. How can I tell MySQL to accept this format in phpMyAdmin? Setting up these tables is the first step in writing a program that will use uploaded gzipped .csv files to maintain the catalog of an e-commerce site.

  • Form Inheritance in Visual Studios designer implementations

    - by CooPzZ
    I'm in the process of Moving a project from Visual Studio 2003 to 2005 and have just seen the The event Click is read-only and cannot be changed when using inherited forms regardless of the Modifier on the Base Forms Controls will make all the Controls from the Base Readonly in the designer (Though in 2003 it didn't work this way). I found this post metioning that this functionality has been temporarily" disabled http://social.msdn.microsoft.com/Forums/en-US/winformsdesigner/thread/c25cec28-67a5-4e30-bb2d-9f8dbd41eb3a Can anyone confirm whether this feature is used anymore? or how to program around it to be able to use the Base Control Events and still have a designer? This is one way I've found but quite painfull when it used to do the plumbing for you. even just hiding one of the controls you have manually do now. Public Class BFormChild Friend Overrides Sub cmdApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdApply_Click(sender, e) End Sub Friend Overrides Sub cmdCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdCancel_Click(sender, e) End Sub Friend Overrides Sub cmdOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdOk_Click(sender, e) End Sub End Class

  • Simple installer for Visual C# Express 2008

    - by espais
    I am looking for some general feedback here. I have a very simple application that I created in VC# Express 2008, with no special dependencies. Now, I am going to release it as open source, and am curious as to how I should deploy it. Do I need to create an installer package with any dll's? Should I just zip up the *.exe file with a README? Also, how should I go about handling the requirement for the .NET framework that a C# program needs?

  • C: getopt with list of acceptable optarg. What is the best practise ?

    - by Xavier Maillard
    Hi, I am writing a C program which is a frontend to a myriad tools. This fronted will be launched like this: my-frontend --action <AN ACTION> As all the tools have the same prefix, let say for this example this prefix is "foo". I want to concatenate "AN ACTION" to this prefix and exec this (if the tool exists). I have written something but my implementation uses strcmp to test that "AN ACTION" is a valid action. Even if this works, I do not like it. So I am looking for a nicer solution that would do the same. The list of possibilities is pretty small (less than 10) and static (the list is "hardcoded") but I am sure there is a more "C-ish" way to do this (using a struct or something like that). As I am not a C expert, I am asking for your help. Regards

  • warning: (Internal error: pc 0x804a6b0 in read in psymtab, but not in symtab.) g++

    - by Sriram
    Hi, I am trying to debug a program using ddd. When I try to enter any function, or within main() itself, I get the following warning: warning: (Internal error: pc 0x804a6b0 in read in psymtab, but not in symtab.) This warning flashes whenever I try to move to another instruction using 'n' or enter or leave a function. I have tried to look this up in other forums, but with no conclusive answer. The code I am trying to debug runs into several files and I am not sure if I can post the entire code here. I am using g++ version: g++ (GCC) 4.4.1 20090725 (Red Hat 4.4.1-2) Any help on this is most welcome. Thanks, Sriram.

Our project is compiled with Release configuration, PDB file is generated. I hope my question is not too naive.

  • Genetic programming in c++, library suggestions?

    - by shuttle87
    I'm looking to add some genetic algorithms to an Operations research project I have been involved in. Currently we have a program that aids in optimizing some scheduling and we want to add in some heuristics in the form of genetic algorithms. Are there any good libraries for generic genetic programming/algorithms in c++? Or would you recommend I just code my own? I should add that while I am not new to c++ I am fairly new to doing this sort of mathematical optimization work in c++ as the group I worked with previously had tended to use a proprietary optimization package. We have a fitness function that is fairly computationally intensive to evaluate and we have a cluster to run this on so parallelized code is highly desirable. So is c++ a good language for this? If not please recommend some other ones as I am willing to learn another language if it makes life easier. thanks!

  • How to tell when my batch of EAP calls are completed?

    - by codemonkie
    This is following my question: http://stackoverflow.com/questions/2607038/c-how-to-consume-web-service-adheres-to-the-event-based-asynchronous-pattern My program is calling the DoStuffAsync() x many times in a batch, hence the callback will get invoked the same number of times upon OnComplete(). Is there a way to find out when my batch is finished such that I can generate a report on the success/failed results? All I can think of is to have a static count variable for x and deduct 1 every time OnComplete() is called, but its kind of silly and error prone I'm afraid. TIA.

  • Is it a solvable problem to generate a regular expression that matches some input set?

    - by Roman
    I provide some input set which contains known separated number of text blocks. I want to make a program that automatically generate 1 or more regular expressions each of which matches every text block in the input set. I see some relatively easy ways to implement a brute-force search. But I'm not an expert in compilers theory. That's why I'm curious: 1) is this problem solvable? or there are some principle impossibility to make such algorithm? 2) is it possible to achieve polynomial complexity for this algorithm and avoid brute forcing?

  • calling a function without knowing the number of parameters in advance

    - by Sourabh Bose
    suppose i have a dll with 2 functions.name of dll="dll1" f1(int a, int b, int c); f2(int a); my program would take the funtion name ,the dll name and a "list" of parameters as input. how would i call the appropriate function with its appropriate parameters. i.e, if input is dll1 f1 list(5,8,9) this would require me to call f1 with 3 parameters if input was dll1 f2 list(8) it would require me to call f2 with one parameter how would i call the function without knowing the number of parameters in advance. further clarification: how do I write code that will call any function with all its arguments by building the argument list dynamically using some other source of information

  • Xcode 5 new bug

    - by user2874675
    Since the recent IOS update last month I have been having issues with this new bug that has hampered my program. The bug is as follows: using a UIButton and I want to insert a value into it, only after my execution ends does a letter actually appear. But if I create a method during execution to tell me, using NSLog, what my properties contain then that letter I added never shows up. I'm thinking I need to find a way to refresh a property during execution instead in the end. For example: Let's say you want to insert the letter F into a UIButton. Immediately after writing F into that UIButton, look to see that F hasn't isn't in there. But it will only show up after that particular execution sequence finishes. Any help would be great. Thanks in advance.

  • administrator permission are recommended for running visual studio sp1 on windows 7 rc

    - by vinayakg
    I get this annoying message everytime I try to run visual studio 2005(even using "Run as Administrator" gives same message). I have VS 2005 Professional with all the latest service packs installed including vs2005 SP1 and vs 2005 update for Vista. I am part of the administrators group on my machine. Still I have this problem. Some read on the web suggests that Running program in Compatibility mode solves the problem. Others also recommend turning off the message forever. Well my question is how do I turn off this warning which seems to bother me even if I am part of administrators group. Does Visual Studio does not run in administrator mode even when I am an administrator or even I use "Run as adminsitrator". Also it would be greate if someone out there can highlight what features of Visual Studio wont be available if Visual Studio is launched as a normal user (User is not an administrator/part of the administrator group) on Windows 7.
