  • Majority Voting in perl?

    - by aliocee
    Hi, i have 5 files containing the same words, i want read each word in all files and decide the winning word by detecting the following characters in a word (*, #, $, &) and generate output file i can only have 2 winners for example: file1 we$ are* ... file2 we$ are* ... file3 we* are$ ... file4 we$ are$ ... file5 we# are& ... output file: we$ - we$ is the winner since it occur in 3 files. are*$ - are* and are$ are the winners since both occur 2 times. here is how i started: #!/usr/local/bin/perl -w sub read_file_line { my $fh = shift; if ($fh and my $line = <$fh>) { chomp($line); return $line; } return; } open(my $f1, "words1.txt") or die "Can't"; open(my $f2, "words2.txt") or die "Can't"; open(my $f3, "words3.txt") or die "Can't"; open(my $f4, "words4.txt") or die "Can't"; open(my $f5, "words5.txt") or die "Can't"; my $r1 = read_file_line($f1); my $r2 = read_file_line($f2); my $r3 = read_file_line($f3); my $r4 = read_file_line($f4); my $r5 = read_file_line($f5); while ($f5) { what can i do here to decide and write the winning word in the output file? $r1 = read_file_line($f1); $r2 = read_file_line($f2); $r3 = read_file_line($f3); $r4 = read_file_line($f4); $r5 = read_file_line($f5); } Thanks.

  • How to avoid "incomplete implementation" warning in partial base class

    - by garph0
    I have created a protocol that my classes need to implement, and then factored out some common functionality into a base class, so I did this: @protocol MyProtocol - (void) foo; - (void) bar; @end @interface Base <MyProtocol> @end @interface Derived_1 : Base @end @interface Derived_2 : Base @end @implementation Base - (void) foo{ //something foo } @end @implementation Derived_1 - (void) bar{ //something bar 1 } @end @implementation Derived_2 - (void) bar{ //something bar 2 } @end In this way in my code I use a generic id<MyProtocol>. The code works (as long as Base is not used directly) but the compiler chokes at the end of the implementation of Base with a warning: Incomplete implementation of class Base Is there a way to avoid this warning or, even better, a more proper way to obtain this partially implemented abstract base class behavior in Objc?

  • Can a function defined in a bookmarklet be called from a page-level script?

    - by Soviut
    I have a bookmarklet that needs to open a new window/tab. In order to avoid the popup blocker, I need to call the window.open() method directly in the bookmarklet ie: at the browser-level. However, I want to keep the bookmarklet updatable by loading external Javascript files. To do this, the bookmarklet needs to append script nodes to the DOM. If i were to put window.open() code in one of these externally loaded scripts, the popup blocker would block it since its page-level. What I want to know is if I can create a wrapper function around window.open() in my bookmarklet, then call it from the externally loaded script? What is the scope and what are the permissions on a wrap such as this?

  • How can I send keypresses to a running process object?

    - by Waffles
    I am trying to make C# launch an application (in this case open office), and start sending that application keypresses such that it would appear as though someone is typing. So ideally, I would be able to send a running open office process the keypress for the letter "d", and open office would then type d on the paper. Can anyone give me direction as per how to go about this? I have tried to do the following: p = new Process(); p.StartInfo.UseShellExecute = true; p.StartInfo.CreateNoWindow = false; p.StartInfo.FileName = processNames.executableName; p.Start(); p.StandardInput.Write("hello"); But that doesn't get me the desired effect - I don't see the text typed out in open office.

  • Split a sting array into a number array in javascript

    - by Wesley Skeen
    I am reading a value from a dropdown list depending on what option is selected. I am using jqPlot to graph the values. jqPlot expects an array of values like [91, 6, 2, 57, 29, 40, 95] but when I read the value in from the dropdown box it is coming in as a whole string "[91, 6, 2, 57, 29, 40, 95]" I tried splitting it but I got ["91", "6", "2", "57", "29", "40", "95"] which wont display the graph correctly. Is there anybody that has encountered something like this before and what can I do to make my values convert into a number array. Thanks for any help

  • Aptana function definition popups

    - by DavidYell
    I've noticed that in Aptana 2.0 over 1.5.1 that when typing a php function, you no longer get the popup window showing the function description and it's parameters. Does anyone know how to get this working again? As I relied on it quite heavily to remember which parameters went where. Open in PHP Manual shortcut Shift+F2 also doesn't work either, so all I can do is open my browser and keep php.net open all the time. Are either of these features functional? I know that Open delcaration has never worked annoyingly, but I had the function popup in 1.5.1 perfectly.

    Hi, How do I load MS Word document (.doc and .docx) to memory (variable) without doing this?: wordApp.Documents.Open I don't want to open MS Word, I just want that text inside. You gave me answer for DOCX, but what about DOC? I want free and high performance solution - not to open 12.000 instances of Word to process all of them. :( Aspose is commercial product, and 900$ is a way too much for what I do.

  • linq with Include and criteria

    - by JMarsch
    How would I translate this into LINQ? Say I have A parent table (Say, customers), and child (addresses). I want to return all of the Parents who have addresses in California, and just the california address. (but I want to do it in LINQ and get an object graph of Entity objects) Here's the old fashioned way: SELECT c.blah, a.blah FROM Customer c INNER JOIN Address a on c.CustomerId = a.CustomerId where a.State = 'CA' The problem I'm having with LINQ is that i need an object graph of concrete Entity types (and it can't be lazy loaded. Here's what I've tried so far: // this one doesn't filter the addresses -- I get the right customers, but I get all of their addresses, and not just the CA address object. from c in Customer.Include(c = c.Addresses) where c.Addresses.Any(a = a.State == "CA") select c // this one seems to work, but the Addresses collection on Customers is always null from c in Customer.Include(c = c.Addresses) from a in c.Addresses where a.State == "CA" select c; Any ideas?

  • Portable Contacts for PHP?

    - by Felix
    I can see Google is implementing the Portable Contacts API for developers to fetch a user's contacts. That seems like exactly what I want to do and I especially like the fact that the protocol is open and through it I can support more than just Google. What I'd like to know is whether there is a library for PHP that implements this protocol, as I don't feel like writing one from scratch / reinventing the wheel. I wouldn't generally post such questions which could be answered by simply googling, but I've done my googling on the subject and can't seem to find any relevant info. BTW, I don't use Zend, so please don't suggest that to me, unless it's the only way possible.

  • Why must I use local path rather than 'svn://' with SVN bindings?

    - by Chad Johnson
    I'm using the Ruby SVN bindings built with SWIG. Here's a little tutorial. When I do this @repository = Svn::Repos.open('/path/to/repository') I can access the repository fine. But when I do this @repository = Svn::Repos.open('svn://localhost/some/path') It fails with /SourceCache/subversion/subversion-35/subversion/subversion/libsvn_subr/io.c:2710: 2: Can't open file 'svn://localhost/format': No such file or directory When I do this from the command line, I do get output svn ls svn://localhost/some/path Any ideas why I can't use the svn:// protocol?

  • PropertyUtils performance

    - by mR_fr0g
    I have a problem where i need to walk through an object graph and pick out a particular property value. My original solution caches a linked list of property names that need to be applied in order to get from point A to point B in the object graph. I then use apache commons PropertyUtils to iterate through the linked list calling getProperty(Object bean, String name) until i have reached point B. My question is around how this will perform compared to perhaps cahing the Method objects for each step. What is propertyUtils doing under the bonnet? Is it doing a lot of reflection / heavy lifting?

  • Purely functional equivalent of weakhashmap?

    - by Jon Harrop
    Weak hash tables like Java's weak hash map use weak references to track the collection of unreachable keys by the garbage collector and remove bindings with that key from the collection. Weak hash tables are typically used to implement indirections from one vertex or edge in a graph to another because they allow the garbage collector to collect unreachable portions of the graph. Is there a purely functional equivalent of this data structure? If not, how might one be created? This seems like an interesting challenge. The internal implementation cannot be pure because it must collect (i.e. mutate) the data structure in order to remove unreachable parts but I believe it could present a pure interface to the user, who could never observe the impurities because they only affect portions of the data structure that the user can, by definition, no longer reach.

  • Exception message (Python 2.6)

File "C:\Python_tests\Exception_Handling\src\exception_handling.py", line 11, in <module> pkl_file = open('monitor.dat', 'rb') So, program would not exits, and I would have useful information.

  • Perl Script to search and replace in .SQL query file with user inputs

    - by T.Mount
    I have a .SQL file containing a large number of queries. They are being run against a database containing data for multiple states over multiple years. The machine I am running this on can only handle running the queries for one state, in one year, at a time. I am trying to create a Perl script that takes user input for the state abbreviation, the state id number, and the year. It then creates a directory for that state and year. Then it opens the "base" .SQL file and searches and replaces the base state id and year with the user input, and saves this new .SQL file to the created directory. The current script I have (below) stops at open(IN,'<$infile') with "Can't open [filename]" It seems that it is having difficulty finding or opening the .SQL file. I have quadruple-checked to make sure the paths are correct, and I have even tried replacing the $path with an absolute path for the base file. If it was having trouble with creating the new file I'd have more direction, but since it can't find/open the base file I do not know how to proceed. #!/usr/local/bin/perl use Cwd; $path = getcwd(); #Cleans up the path $path =~ s/\\/\//sg; #User inputs print "What is the 2 letter state abbreviation for the state? Ex. 'GA'\n"; $stlet = <>; print "What is the 2 digit state abbreviation for the state? Ex. '13'\n"; $stdig = <>; print "What four-digit year are you doing the calculations for? Ex. '2008'\n"; $year = <>; chomp $stlet; chomp $stdig; chomp $year; #Creates the directory mkdir($stlet); $new = $path."\/".$stlet; mkdir("$new/$year"); $infile = '$path/Base/TABLE_1-26.sql'; $outfile = '$path/$stlet/$year/TABLE_1-26.sql'; open(IN,'<$infile') or die "Can't open $infile: $!\n"; open(OUT,">$infile2") or die "Can't open $outfile: $!\n"; print "Working..."; while (my $search = <IN>) { chomp $search; $search =~ s/WHERE pop.grp = 132008/WHERE pop.grp = $stdig$year/g; print OUT "$search\n"; } close(IN); close(OUT); I know I also probably need to tweak the regular expression some, but I'm trying to take things one at a time. This is my first Perl script, and I haven't really been able to find anything that handles .SQL files like this that I can understand. Thank you!

  • Stuck on solving the Minimal Spanning Tree problem.

    - by kunjaan
    I have reduced my problem to finding the minimal spanning tree in the graph. But I want to have one more constraint which is that the total degree for each vertex shouldnt exceed a certain constant factor. How do I model my problem? Is MST the wrong path? Do you know any algorithms that will help me? One more problem: My graph has duplicate edge weights so is there a way to count the number of unique MSTs? Are there algorithms that do this? Thank You. Edit: By degree, I mean the total number of edges connecting the vertex. By duplicate edge weight I mean that two edges have the same weight.

  • How can we protect ourselves from other third parties installing DLLs with the same names as some of

    - by Integer Poet
    Our product includes several DLLs built from open source into files with default names as delivered by the open source developers. We're careful to install the files in our own directories and we carefully manage the search path (only for our processes) to keep the loader happy. Another developer -- a towering intellect -- decided it would be easier to install their own build of some of the same open source into C:\WINDOWS under the same default DLL filenames. Consequently, when we launch a process which depends on these open source DLLs, the system searches C:\WINDOWS before our directories and finds the DLLs installed by the other developer. And they are, of course, incompatible. Ideas which have occurred to me so far: rename all our DLLs to avoid the default names, which would only make it less likely we would encounter collisions load all our DLLs by full path so the loader captures their names into RAM and doesn't search anywhere else the next time they are requested For various reasons, neither of these options is palatable at the moment. What else can we do to defend ourselves against the towering intellects of the world?
