  • Why does this crash: stringByAppendingFormat

    - by Emil
    Hey. My code crashes at this function (at the stringByAppendingFormat: with error objc_msgSend() selector name: stringByAppendingFormat). This is that line: // imagesPath = ...iPhone Simulator/4.0/Applications/NUMBERS/Documents/images UIImage *image = [[UIImage alloc] initWithContentsOfFile:[imagesPath stringByAppendingFormat:@"/%d.png", [[self.postsArrayID objectAtIndex:row] intValue]]]; Could it have something to do with the retaining of objects? Thanks :)

  • I need a dictionary-like mapping between characters and other kinds of objects. Which class would be

    - by nullPointerException
    This is in Squeak/Pharo. If I want to have a mapping between Character objects like $a and $b to other kinds of objects, and want to look up those other objects based on the Character, what is the best class to use? Dictionary is an obvious choice, but seems wasteful to be hashing character objects which are basically already numbers. I guess what I want is a kind of array where the character value (number) is used as an index/offset, but I am not sure if this is possible with Unicode.

  • Why file upload error codes in php miss number '5'?

    - by Majid
    I am writing a custom error handling/reporting function for php file upload and I noticed that the error codes returned is one of numbers 0 to 8 except 5. Is this a typo in the source I am using or is it really this way? And if it is so, I am curious why they have skipped number '5'. Thanks.

  • ActionScript Binding Array Objects?

    i would like to update the numbers i've added to an array from variables, when those variables change. is it possible change these variables and have the array update automatically? var first:Number = 1; var second:Number = 2; var myArray:Array = new Array(first, second); first = 3; second = 4; trace(myArray) //outputs 1,2

  • The fundamentals of Hash tables?

    - by kylex
    I'm quite confused about the basic concepts of a Hash table. If I were to code a hash how would I even begin? What is the difference between a Hash table and just a normal array? Basically if someone answered this question I think all my questions would be answered: If I had 100 randomly generated numbers (as keys), how would I implement a hash table and why would that be advantageous over an array? Psuedo-code or Java would be appreciated as a learning tool...

  • C++ Euler-Problem 14 Program Freezing

    - by Tim
    I'm working on Euler Problem 14: http://projecteuler.net/index.php?section=problems&id=14 I figured the best way would be to create a vector of numbers that kept track of how big the series was for that number... for example from 5 there are 6 steps to 1, so if ever reach the number 5 in a series, I know I have 6 steps to go and I have no need to calculate those steps. With this idea I coded up the following: #include <iostream> #include <vector> #include <iomanip> using namespace std; int main() { vector<int> sizes(1); sizes.push_back(1); sizes.push_back(2); int series, largest = 0, j; for (int i = 3; i <= 1000000; i++) { series = 0; j = i; while (j > (sizes.size()-1)) { if (j%2) { j=(3*j+1)/2; series+=2; } else { j=j/2; series++; } } series+=sizes[j]; sizes.push_back(series); if (series>largest) largest=series; cout << setw(7) << right << i << "::" << setw(5) << right << series << endl; } cout << largest << endl; return 0; } It seems to work relatively well for smaller numbers but this specific program stalls at the number 113382. Can anyone explain to me how I would go about figuring out why it freezes at this number? Is there some way I could modify my algorithim to be better? I realize that I am creating duplicates with the current way I'm doing it: for example, the series of 3 is 3,10,5,16,8,4,2,1. So I already figured out the sizes for 10,5,16,8,4,2,1 but I will duplicate those solutions later. Thanks for your help!

  • R implementation of sorting by reversals

    - by user1357015
    I was wondering if there is an implementation in R where it sorts a permutation of n numbers into the original 1...n sequence and provides the number of reversals needed. Eg an implementation of the "sorting by reversals" or "sorting by translocation" as outlined in this ppt. Specifically, I have a permutation of a sequence of n elements, pi(n), and I want to figure out how close it is to the original sequence. The number of reversals seems a good metric. Thanks!

  • How to generate unique serial number of machine in Delphi?

    - by noxwow
    Hi, I have question how to generate unique serial number of machine in Delphi? I tried to do this using the ID the motherboard or processor, but unfortunately it's unfortunately supported. Partition serial numbers, etc. fall off, because it is changing after the formatted. I'm looking for something that doesn't change after the formatted. Has anyone any idea?

  • How can I left-justify numerical output in fortran?

    - by mishaF
    I am writing some simple output in fortran, but I want whitespace delimiters. If use the following statement, however: format(A20,ES18.8,A12,ES18.8) I get output like this: p001t0000 3.49141273E+01obsgp_oden 1.00000000E+00 I would prefer this: p001t0000 3.49141273E+01 obsgp_oden 1.00000000E+00 I tried using negative values for width (like in Python) but no dice. So, is there a way to left-justify the numbers? Many thanks in advance!

  • How to write stored procedure to do this?

    - by chobo
    I would like to create a stored procedure that takes in a string of comma separated values like this "1,2,3,4", and break it apart and use those numbers to run a query on a different table. so in the same stored procedure it would do something like select somefield from sometable where somefield = 1 select somefield from sometable where somefield = 2 select somefield from sometable where somefield = 3 select somefield from sometable where somefield = 4 Thanks!

    Contract.all(:conditions => ['voided == ?', 0]).size => 364 Contract.all(:conditions => ['voided != ?', 0]).size => 8 Contract.all.size => 441 the 3 numbers does not added up (364 + 8 != 441). What's the proper way write the :conditions to count the rows which the voided column value is NULL or equal to zero?

  • A comprehensive regex for phone number validation

    - by Nicholas Trandem
    I'm trying to put together a comprehensive regex to validate phone numbers. Ideally it would handle international formats, but it must handle US formats, including the following: 1-234-567-8901 1-234-567-8901 x1234 1-234-567-8901 ext1234 1 (234) 567-8901 1.234.567.8901 1/234/567/8901 12345678901 I'll answer with my current attempt, but I'm hoping somebody has something better and/or more elegant.

  • C# Check for missing number in sequence

    - by Jon
    I have an List<int> which contains 1,2,4,7,9 for example. I have a range from 0 to 10. Is there a way to determine what numbers are missing in that sequence? I thought LINQ might provide an option but I can't see one In the real world my List could contain 100,000 items so performance is key

  • Silverlight MVVM add record from user control

    - by strattonn
    I have a User Control for searching container numbers. If the user enters a container number that's new to the system then I want to tell the VM "I have a new record to add". The MVVM method avoids using Events to communicate with the VM as they create code-behind. Should I create a Dependency Property to trigger the VM but I don't think I've seen other controls with a "NewRecord" property? Any thoughts?

  • java random percentages

    - by erw
    I need to generate n percentages (integers between 0 and 100) such that the sum of all n numbers adds up to 100. If I just do nextInt() n times, each time ensuring that the parameter is 100 minus the previously accumulated sum, then my percentages are biased (i.e. the first generated number will usually be largest etc.). How do I do this in an unbiased way?

  • Getting every odd variable in a list?

  • How do you solve this Haskell problem?

    - by Linda Cohen
    I want to define a function replicate to replicate a list of numbers by its value using only list comprehension, for example: replicate [5,1,3,2,8,1,2] output: [5,5,5,5,5,1,3,3,3,2,2,8,8,8,8,8,8,8,8,1,2,2] I know this would be easy to use the 'replicate' built in function but only list comprehension is allow, how can I do this? THANKS!
