  • changing .emacs to use IronPython.exe and using code completion for IronPython modules ?

    - by KaluSingh Gabbar
    I configured my Emacs for code completion and other help using this link (from another question here on SO). I am a complete newbie to emacs. Can anyone tell me what should I change so it (rope, ropemacs, pymacs, yasnippet etc) picks up symbols of IronPython modules for code completion and snippets. Also I want to map: C-x RET - to invoke IronPython.exe and not Python.exe (any clue on how to do that) PS I am using Emacs with Cygwin on XP machine

  • Seam - list all components

    - by Walter White
    Hi all, I would like to get a list of all the components so that I can further process them. Is this possible, if so, how can I do that? I don't believe I can observe all postCreate events since it is simply an exact match and not a regular expression. @Observer("org.jboss.seam.postCreate.") You can only observe those events and not * as it is put into a map where the key is a string. Any ideas? Walter

  • Declaration of arrays before "normal" variables in c?

    - by bjarkef
    Hi We are currently developing an application for a msp430 MCU, and are running into some weird problems. We discovered that declaring arrays withing a scope after declaration of "normal" variables, sometimes causes what seems to be undefined behavior. Like this: foo(int a, int *b); int main(void) { int x = 2; int arr[5]; foo(x, arr); return 0; } foo sometimes is passed a pointer as the second variable, that does not point to the arr array. We verify this by single stepping through the program, and see that the value of the arr variable in the main scope is not the same as the value of the b pointer variable in the foo scope. And no, this is not really reproduceable, we have just observed this behavior once in a while. Changing the example seems to solve the problem, like this: foo(int a, int *b); int main(void) { int arr[5]; int x = 2; foo(x, arr); return 0; } Does anybody have any input or hints as to why we experience this behavior? Or similar experiences? The MSP430 programming guide specifies that code should conform to the ANSI C89 spec. and so I was wondering if it says that arrays has to be declared before non-array variables? Any input on this would be appreciated.

  • Matlab and .net problem with character string function input

    - by Peter
    I have a MATLAB function that I've compiled into a .net library. The function is a simple one that takes a character array as an input and a numeric array as output: function insert = money(dateLimit) .. insert = [1 2]; The function works fine when no function arguments are specified (a default argument is provided inside the function) Dim sf As New SpreadFinder.SpreadFinder Dim output = sf.money() As soon as an argument is specified .net complains. I'm thinking this should be easy and has been done before but searching through MATLAB documentation doesn't offer much help. Here's what I've tried. The sf.money() overload for the function with arguments is (numArgsOut as Integer, argsOut as MWArray, argsIn as MWArray) and hence that's what I've tried. What am I missing? Dim sf As New SpreadFinder.SpreadFinder Dim inputArgs(1) As Arrays.MWCharArray Dim dateLimitString As String = "some string" inputArgs(0) = New Arrays.MWCharArray(dateLimitString) Dim outputArgs(1) As Arrays.MWNumericArray outputArgs(0) = New Arrays.MWNumericArray() sf.money(1, outputArgs, inputArgs) Gives System.NullReferenceException : Object reference not set to an instance of an object. at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Int32 numArgsOut, Int32 numArgsIn, MWArray[] argsIn) at MathWorks.MATLAB.NET.Utility.MWMCR.EvaluateFunction(String functionName, Int32 numArgsOut, MWArray[]& argsOut, MWArray[] argsIn) at SpreadFinder.SpreadFinder.money(Int32 numArgsOut, MWArray[]& argsOut, MWArray[] argsIn)

  • Need to format character precedence in Strings.

    - by Christian
    I'm currently writing a Roman Numeral Converter for the fun of it. The problem works up to the aforementioned character precedence. Since Roman Numerals are not positional, i.e. III does not symbolize 1*whatever base^2 + 1*whatever base^1 + 1*whatever base^0. That of course makes it hard when somebody types in XIV and I need to make sure that the I is not added in this case, but rather subtracted. I'm not sure how to do this. What would be the best approach to tackle this? I have both the Roman Symbols and their respective decimal numbers stored in arrays: const char cRomanArray[] = "IVXLCDM"; const int romanArray[] = { 1, 5, 10, 50, 100, 500, 1000 }; so it wouldn't be too hard for me to brute-force the damn thing by simply checking the precedence within the array, i.e. if the symbol is smaller than the next symbol, i.e. in the exampe 'XIV' if 'I' is smaller than 'V', in which case it would be because I have ordered them in the array, then I could make it subtract the value instead of add. But this seems like a very ugly solution. Are there perhaps any better ones? I was thinking something along the lines of Regular Expressions maybe( forgive me if that sounds like a horrible idea, I haven't used RegExp yet, but it sounds like it could do what I need, and that's to determine the characters in a string.)

  • remove text in parentheses and the parentheses using .filter() or .slice()

    - by liz
    i have a table with code like this: <tr> <th scope="row">5-17</th> <td>23.6 (22.0-24.0)</td> <td>18.0 (17-20.0)</td> </tr> <tr> <th scope="row">Total 0-17</th> <td>20.6 (8-15.6)</td> <td>16.1 (22.2-24.0)</td> </tr> i am using the following function to find the contents of the table cells and bring it into an array: var l1 = $('#datatable td:nth-child(2)').map(function() { return $(this).text(); }).get(); the table fragment's id is "datatable". this returns properly, however i am putting this array into jqPlot and it cant read the stuff between the parentheses or the parentheses themselves. i need the data to remain in the table however because we are displaying both the table and the chart. i cant reformat (add spans around the content i want to remove etc) because these tables are being generated by another piece of software. i think what i need to do is either slice off after the space or use a regex to find and remove. not sure how to proceed with either of these. thanks!

  • Time complexity of a certain program

    - by HokageSama
    In a discussion with my friend i am not able to predict correct and tight time complexity of a program. Program is as below. /* This Function reads input array "input" and update array "output" in such a way that B[i] = index value of nearest greater value from A[i], A[i+1] ... A[n], for all i belongs to [1, n] Time Complexity: ?? **/ void createNearestRightSidedLargestArr(int* input, int size, int* output){ if(!input || size < 1) return; //last element of output will always be zero, since no element is present on its right. output[size-1] = -1; int curr = size - 2; int trav; while(curr >= 0){ if(input[curr] < input[curr + 1]){ output[curr] = curr + 1; curr--; continue; } trav = curr + 1; while( input[ output [trav] ] < input[curr] && output [trav] != -1) trav = output[trav]; output[curr--] = output[trav]; } } I said time complexity is O(n^2) but my friend insists that this is not correct. What is the actual time complexity?

  • How to deserialize MXML with PHP?

    - by Ivan Petrushev
    Hello, I have an array structure that have to be converted to MXML. I know of PEAR XML_Serialize extension but it seems the output format it produces is a bit different. PHP generated XML: <zone columns="3"> <select column="1" /> <select column="4" /> </zone> MXML format: <mx:zone columns="3"> <mx:select column="1" /> <mx:select column="4" /> </mx:zone> Is that "mx:" prefix required for all the tags? If yes, can I make the XML_Serialize put it before each tag (without renaming my data structure fields to "mx:something")? Here are my options for XML_Serialize: $aOptions = array('addDecl' => true, 'indent' => " ", 'rootName' => 'template', 'scalarAsAttributes' => true, 'mode' => 'simplexml');

  • NSTableView Drag and Drop not working

    - by macatomy
    Hi, I'm trying to set up very basic drag and drop for my NSTableView. The table view has a single column (with a custom cell). The column is bound to an NSArrayController, and the array controller's content array is bound to an NSArray on my controller object. The data displays fine in the table. I connected the dataSource and delegate outlets of the table view to my controller object, and then implemented these methods: - (BOOL)tableView:(NSTableView *)aTableView writeRowsWithIndexes:(NSIndexSet *)rowIndexes toPasteboard:(NSPasteboard *)pboard { NSLog(@"dragging"); return YES; } - (NSDragOperation)tableView:(NSTableView*)tv validateDrop:(id <NSDraggingInfo>)info proposedRow:(NSInteger)row proposedDropOperation:(NSTableViewDropOperation)op { return NSDragOperationEvery; } - (BOOL)tableView:(NSTableView *)aTableView acceptDrop:(id <NSDraggingInfo>)info row:(NSInteger)row dropOperation:(NSTableViewDropOperation)operation { return YES; } I also registered the drag types in -awakeFromNib: #define MyDragType @"MyDragType" - (void)awakeFromNib { [super awakeFromNib]; [_myTable registerForDraggedTypes:[NSArray arrayWithObjects:MyDragType, nil]]; } The problem is that the -tableView:writeRowsWithIndexes:toPasteboard: method is never called. I've looked at a bunch of examples and I can't figure out anything I'm doing wrong. Could the problem be that I'm using a custom cell? Is there something I'm supposed to override in the cell subclass to enable this functionality? EDIT: Confirmed. Switching the custom cell for a regular NSTextFieldCell made dragging work. Now, how do I make drag and drop work with my custom cell?

  • Converting timestamp to time ago in php e.g 1 day ago, 2 days ago...

    - by cosmicbdog
    hi everyone, i am trying to convert a timestamp of the format: 2009-09-12 20:57:19 and turn it into something like '3 minutes ago' with php. I found a useful script to do this, but I think its looking for a different format to be used as the time variable. The script I'm wanting to modify to work with this format is: function _ago($tm,$rcs = 0) { $cur_tm = time(); $dif = $cur_tm-$tm; $pds = array('second','minute','hour','day','week','month','year','decade'); $lngh = array(1,60,3600,86400,604800,2630880,31570560,315705600); for($v = sizeof($lngh)-1; ($v >= 0)&&(($no = $dif/$lngh[$v])<=1); $v--); if($v < 0) $v = 0; $_tm = $cur_tm-($dif%$lngh[$v]); $no = floor($no); if($no <> 1) $pds[$v] .='s'; $x=sprintf("%d %s ",$no,$pds[$v]); if(($rcs == 1)&&($v >= 1)&&(($cur_tm-$_tm) > 0)) $x .= time_ago($_tm); return $x; } I think on those first few lines its trying to do something that looks like this (different date format math): $dif = 1252809479 - 2009-09-12 20:57:19; How would I go about converting my timestamp into that (unix?) format?

  • computing hash values, integral types versus struct/class

    - by aaa
    hello I would like to know if there is a difference in speed between computing hash value (for example std::map key) of primitive integral type, such as int64_t and pod type, for example struct { int16_t v[4]; };. I know this is going to implementation specific, so my question ultimately pertains to gnu standard library. Thanks

  • Why do I have to unserialize this serialized value twice? (wordpress/bbpress maybe_serialize)

  • OutOfMemoryException when I read FileStream 500 MB

My Code is: using (var fs3 = new FileStream(filePath2, FileMode.Open, FileAccess.Read)) { byte[] b2 = ReadFully(fs3, 1024); } public static byte[] ReadFully(Stream stream, int initialLength) { // If we've been passed an unhelpful initial length, just // use 32K. if (initialLength < 1) { initialLength = 32768; } byte[] buffer = new byte[initialLength]; int read = 0; int chunk; while ((chunk = stream.Read(buffer, read, buffer.Length - read)) > 0) { read += chunk; // If we've reached the end of our buffer, check to see if there's // any more information if (read == buffer.Length) { int nextByte = stream.ReadByte(); // End of stream? If so, we're done if (nextByte == -1) { return buffer; } // Nope. Resize the buffer, put in the byte we've just // read, and continue byte[] newBuffer = new byte[buffer.Length * 2]; Array.Copy(buffer, newBuffer, buffer.Length); newBuffer[read] = (byte)nextByte; buffer = newBuffer; read++; } } // Buffer is now too big.

  • Team matchups for Dota Bot

    - by Dan
    I have a ghost++ bot that hosts games of Dota (a warcraft 3 map that is played 5 players versus 5 players) and I'm trying to come up with good formulas to balance the players going into a match based on their records (I have game history for several thousand games). I'm familear with some of the concepts required to match up players, like confidence based on sample size of the number of games they played, and also perameter approximation and degrees of freedom and thus throwing out any variables that don't contribute enough to the r^2. My bot collects quite a few variables for each player from each game: The Important ones: Win/Lose/Game did not finish # of Player Kills # of Player Deaths # of Kills player assisted The not so important ones: # of enemy creep kills # of creep sneak attacks # of neutral creep kills # of Tower kills # of Rax kills # of courier kills Quick explination: The kills/deaths don't determine who wins, but the gold gained and lost from this usually is enough to tilt the game. Tower/Rax kills are what the goal of the game is (once a team looses all their towers/rax their thrown can be attacked if that is destroyed they lose), but I don't really count these as important because it is pretty random who gets the credit for the tower kill, and chances are if you destroy a tower it is only because some other player is doing well and distracting the otherteam elsewhere on the map. I'm getting a bit confused when trying to deal with the fact that 5 players are on a team, so ultimately each individual isn't that responsible for the team winner or losing. Take a player that is really good at killing and has 40 kills and only 10 deaths, but in their 5 games they've only won 1. Should I give him extra credit for such a high kill score despite losing? (When losing it is hard to keep a positive kill/death ratio) Or should I dock him for losing assuming that despite the nice kill/death ratio he probably plays in a really greedy way only looking out for himself and not helping the team? Ultimately I don't think I have to guess at questions like this because I have so much data... but I don't really know how to look at the data to answer questions like this. Can anyone help me come up with formulas to help team balance and predict the outcome? Thanks, Dan

  • Interface and partial classes

    - by Tomek Tarczynski
    According to rule SA1201 in StyleCop elements in class must appear in correct order. The order is following: Fields Constructors Finalizers (Destructors) Delegates Events Enums Interfaces Properties Indexers Methods Structs Classes Everything is ok, except of Interfaces part, because Interface can contain mehtods, events, properties etc... If we want to be strict about this rule then we won't have all members of Interface in one place which is often very useful. According to StyleCop help this problem can be solved by spliting class into partial classes. Example: /// <summary> /// Represents a customer of the system. /// </summary> public partial class Customer { // Contains the main functionality of the class. } /// <content> /// Implements the ICollection class. /// </content> public partial class Customer : ICollection { public int Count { get { return this.count; } } public bool IsSynchronized { get { return false; } } public object SyncRoot { get { return null; } } public void CopyTo(Array array, int index) { throw new NotImplementedException(); } } Are there any other good solutions to this problem?

  • Appending data to NSFetchedResultsController during find or create loop

    - by Justin Williams
    I have a table view that is managed by an NSFetchedResultsController. I am having an issue with a find-or-create operation, however. When the user hits the bottom of my table view, I am querying my server for another batch of content. If it doesn't exist in the local cache, we create it and store it. If it does exist, however, I want to append that data to the fetched results controller and display it. I can't quite figure that part out. Here's what I'm doing thus far: Passing the returned array of values from my server to an NSOperation to process. In the operation, create a new managed object context to work with. In the operation, I iterate through the array and execute a fetch request to see if the object exists (based on its server id). If the object doesn't exist, we create it and insert it into the operations' managed object context. After the iteration completes, we save the managed object context, which triggers a merge notification on my main thread. At this point, any objects that weren't locally cached in my Core Data store before will appear, but the ones that previously existed do not come along for the ride. I feel like it's something simple I'm missing, and could use a nudge in the right direction.
