  • Strange ruby behavior when using Hash.new([])

    - by Valentin Vasilyev
    Consider this code: h=Hash.new(0) #new hash pairs will by default have 0 as values h[1]+=1 # {1=>1} h[2]+=2 # {2=>2} that's all fine, but: h=Hash.new([]) #empty array as default value h[1]<<=1 #{1=>[1]} - OK h[2]<<=2 #{1=>[1,2], 2=>[1,2]} # why ?? At this point I expect the hash to be: {1=>[1], 2=>[2]} But something goes wrong. Does anybody know what happens?

  • Do I need to release a copied NSObjects - Objective-c

    - by ncohen
    Hi everyone, I was wondering if I need to release a copied NSObject? For example, I create only one dictionary that I copy into an array: Code: for (int num = 0; num < [object count]; num++) { [dictionary setObject:[object objectAtIndex:num] forKey:@"x"]; [array addObject:[dictionary copy]]; } Do I have to release the dictionary? If yes, when? Thanks

  • What is the single most influential book every programmer should read?

    - by NotMyself
    If you could go back in time and tell yourself to read a specific book at the beginning of your career as a developer, which book would it be? I expect this list to be varied and to cover a wide range of things. For me, the book would be Code Complete. After reading that book, I was able to get out of the immediate task mindset and begin to think about the bigger picture, quality and maintainability.

  • How does PHP work - literature

    - by Ondrej Slinták
    I'm interested in literature (articles on internet, in magazines, books, podcasts - I don't really mind anything) that describes how PHP works internally, about its gotchas and perhaps some advanced functions. Is there anything like this out there? I tried to search on Google, but majority of articles were about starting with PHP and its basic functions. Any input is really welcome as I'm trying to understand the language internally - I'm tired of my mindless typing of code without understanding its essence.

    I use the delegate method connection:willSendRequest:redirectResponse: in SDK 2.2, the code like below: - (NSURLRequest *)connection:(NSURLConnection *)con willSendRequest:(NSURLRequest *)request redirectResponse:(NSURLResponse *)redirectResponse { if(redirectResponse) { if(!self.autoRedirect) { NSLog(@"response will redirect"); request = nil; } } return request; if the request is returned to nil ,it seems it hangs up here, and delegate didReceiveData will not get called. but it works in SDK 3. Any suggestions about this?

  • Core-Data Can't pass managedObjectContext from app delegate to view controller

    - by yahuie
    I'm making a core-data application that is view based. I can create the managedObjectContext and 'use' it in the app delegate, but can not pass it to the mainviewcontroller. Probably something simple, but I can't find the problem after looking for quite a while. The managedObjectModel is nil in the mainviewcontroller.

  • How to build a function on the fly in java?

    - by stereos
    I'm parsing a text file that is being mapped to some java code like such: public void eval(Node arg) { if(arg.data.equals("rand")) { moveRandomly(); } else if(arg.data.equals("home")) { goHome(); }//snip.. This is going to need to be re-evaluated about a thousand times and I'd rather not have to traverse the whole thing every time. Is there any way to make this traversal once and then have it be a function that is called every other time?

  • Playing Multiple Sounds at Once in Qt

    - by Ben
    I'm trying to play background music along with sound effects using Qt. However, I can't get more than one sound to play at once. For example: QSound::play("Music.wav"); QSound::play("Effect.wav"); When this code is run (on Windows), you can hear Music.wav just start to play, but then it stops and Effect.wav plays. Is there any way to get the two sounds to play at once?

  • Uneditable file and Unreadable(for further processing) file( WHY? ) after processing it through C++

    - by mgj
    Hi...:) This might look to be a very long question to you I understand, but trust me on this its not long. I am not able to identify why after processing this text is not being able to be read and edited. I tried using the ord() function in python to check if the text contains any Unicode characters( non ascii characters) apart from the ascii ones.. I found quite a number of them. I have a strong feeling that this could be due to the original text itself( The INPUT ). Input-File: Just copy paste it into a file "acle5v1.txt" The objective of this code below is to check for upper case characters and to convert it to lower case and also to remove all punctuations so that these words are taken for further processing for word alignment #include<iostrea> #include<fstream> #include<ctype.h> #include<cstring> using namespace std; ifstream fin2("acle5v1.txt"); ofstream fin3("acle5v1_op.txt"); ofstream fin4("chkcharadded.txt"); ofstream fin5("chkcharntadded.txt"); ofstream fin6("chkprintchar.txt"); ofstream fin7("chknonasci.txt"); ofstream fin8("nonprinchar.txt"); int main() { char ch,ch1; fin2.seekg(0); fin3.seekp(0); int flag = 0; while(!fin2.eof()) { ch1=ch; fin2.get(ch); if (isprint(ch))// if the character is printable flag = 1; if(flag) { fin6<<"Printable character:\t"<<ch<<"\t"<<(int)ch<<endl; flag = 0; } else { fin8<<"Non printable character caught:\t"<<ch<<"\t"<<int(ch)<<endl; } if( isalnum(ch) || ch == '@' || ch == ' ' )// checks for alpha numeric characters { fin4<<"char added: "<<ch<<"\tits ascii value: "<<int(ch)<<endl; if(isupper(ch)) { //tolower(ch); fin3<<(char)tolower(ch); } else { fin3<<ch; } } else if( ( ch=='\t' || ch=='.' || ch==',' || ch=='#' || ch=='?' || ch=='!' || ch=='"' || ch != ';' || ch != ':') && ch1 != ' ' ) { fin3<<' '; } else if( (ch=='\t' || ch=='.' || ch==',' || ch=='#' || ch=='?' || ch=='!' || ch=='"' || ch != ';' || ch != ':') && ch1 == ' ' ) { //fin3<<" '; } else if( !(int(ch)>=0 && int(ch)<=127) ) { fin5<<"Char of ascii within range not added: "<<ch<<"\tits ascii value: "<<int(ch)<<endl; } else { fin7<<"Non ascii character caught(could be a -ve value also)\t"<<ch<<int(ch)<<endl; } } return 0; } I have a similar code as the above written in python which gives me an otput which is again not readable and not editable The code in python looks like this: #!/usr/bin/python # -*- coding: UTF-8 -*- import sys input_file=sys.argv[1] output_file=sys.argv[2] list1=[] f=open(input_file) for line in f: line=line.strip() #line=line.rstrip('.') line=line.replace('.','') line=line.replace(',','') line=line.replace('#','') line=line.replace('?','') line=line.replace('!','') line=line.replace('"','') line=line.replace('?','') line=line.replace('|','') line = line.lower() list1.append(line) f.close() f1=open(output_file,'w') f1.write(' '.join(list1)) f1.close() the file takes ip and op at runtime.. as: python punc_remover.py acle5v1.txt acle5v1_op.txt The output of this file is in "acle5v1_op.txt" now after processing this particular output file is needed for further processing. This particular file "aclee5v1_op.txt" is the UNREADABLE Aand UNEDITABLE File that I am not being able to use for further processing. I need this for Word alignment in NLP. I tried readin this output with the following program #include<iostream> #include<fstream> using namespace std; ifstream fin1("acle5v1_op.txt"); ofstream fout1("chckread_acle5v1_op.txt"); ofstream fout2("chcknotread_acle5v1_op.txt"); int main() { char ch; int flag = 0; long int r = 0; long int nr = 0; while(!(fin1)) { fin1.get(ch); if(ch) { flag = 1; } if(flag) { fout1<<ch; flag = 0; r++; } else { fout2<<"Char not been able to be read from source file\n"; nr++; } } cout<<"Number of characters able to be read: "<<r; cout<<endl<<"Number of characters not been able to be read: "<<nr; return 0; } which prints the character if its readable and if not it doesn't print them but I observed the output of both the file is blank thus I could draw a conclusion that this file "acle5v1_op.txt" is UNREADABLE AND UNEDITABLE. Could you please help me on how to deal with this problem.. To tell you a bit about the statistics wrt the original input file "acle5v1.txt" file it has around 3441 lines in it and around 3 million characters in it. Keeping in mind the number of characters in the file you editor might/might not be able to manage to open the file.. I was able to open the file in gedit of Fedora 10 which I am currently using .. This is just to notify you that opening with a particular editor was not actually an issue at least in my case... Can I use scripting languages like Python and Perl to deal with this problem if Yes how? could please be specific on that regard as I am a novice to Perl and Python. Or could you please tell me how do I solve this problem using C++ itself.. Thank you...:) I am really looking forward to some help or guidance on how to go about this problem....

  • SubSonic error: db.tables with a ~ in the name result in a "Character is not valid" error

    - by Steven
    I renamed a database table and added a ~ character to the table name (my way of notifying it is a backup of something). After generating the SubSonic files, my Visual Studio gives a "Character not valid" error on file "AllStructs.vb" When looking into this file the following line of code was generated; Public Shared ReadOnly DbTable1~old As String = "dbtable1~old". I assume this character has to be filtered out of the db.table names when generating the SubSonic names?

  • Calling a function in an iframe from a parent in firefox

    - by wyatt
    I'm trying to call a function, test(), of an iframe from the parent document using the code subframe.test(); subframe refers correctly to the iframe, alert(subframe) returns [object HTMLIFrameElement], and the function runs in both IE7 and opera (9.23), but not firefox (3.0), chrome (3.0) or safari (3.03 beta windows). I assume these browsers support the functionality, so wondering if perhaps I'm using an incorrect call which IE and Opera support anyway, which wouldn't surprise me.

  • How to detect which Windows account is running a .net application?

    - by Bryan
    Hi, I'm writing a sharepoint web part. It writes logs into a file (by using StreamWriter). However, logs are written only for users whose accounts are administrators on the server hosting the web part. I want to detect which account (probably not by using SPUser) is executing web part's code, so that I can have logs generated for less privileged users. Is that possible? Thanks
