• cakephp VS codeigniter VS zend framework

  - by i need help

  Very possibly very related: What PHP framework would you choose for a new application and why? Zend or CakePHP? Which one is better? Some people say CakePHP is better for php 4, what do you think? In my case, I would like the following: Lesser code to write, have really strong library and plugin base. Always have new library etc added in from contributor, eg: google map and etc... Ability to use together with the templating system like smarty. Have ACL that can control all the permission level issue. Load class when needed, unload when not needed. Load class once and use globally. Can run in windows environment (I am using xampp to run my php in windows.) After the site done, I will upload all codes into windows 2008 server (using php 5)

• Custom array class with assotiated objects

  - by FancyDancy

  I have a simple structure, it's just an array of model's objects. For example, it's a users with books. @books = Book.find(:all, :include = :users) I need to check, does user have a book? I have written a helper method: def has_book?(user_id) @books.select{|b| b.user_id == user_id}.any? end Then, i need to get only books from selected library def in_library(n) @books.select{|b| b.library == n} end I have tried to make custom Array class: class BooksList < Array def initialize(books) self << books end # its my custom methods def has_book?(user_id) self.select{|b| b.user_id == user_id}.any? end def in_library(n) self.select{|b| b.library == n} end end It works, but i have only one problem. I can't access Book's assotiated object (user). So i can't write: @books = BookList.new(Book.find(:all, :include => :users)) @books.first.user.id # it says undefined method `user' for #<Array:0x104b43e08>

• Chrome Extension: how to capture selected text and send to a web service

  - by phil swenson

  For the Google Chrome extension, I need to capture selected text in a web page and send to a web service. I'm stuck! First I tried a bookmarklet, but Chrome on Mac seems to have some bookmarklet bugs so I decided to write an extension. I use this code in my ext: function getSelText(){ var txt = 'nothing'; if (window.getSelection){ txt = "1" + window.getSelection(); } else if (document.getSelection) { txt = "2" + document.getSelection(); } else if (document.selection) { txt = "3" + document.selection.createRange().text; } else txt = "wtf"; return txt; } var selection = getSelText(); alert("selection = " + selection); When I click on my extension icon, I get a "1". So I think the act of selecting outside the browser window is causing the text to not be seen by the browser as "selected" any more. Just a theory.... thoughts?

• How to format a dos path to a unix path on cygwin command line

  - by Jennette

  When using Cygwin, I frequently copy a Windows path and manually edit all of the slashes to Unix format. For example, if I am using Cygwin and need to change directory I enter: cd C:\windows\path then edit this to cd C:/windows/path (Typically, the path is much longer than that). Is there a way to use sed, or something else to do this automatically? For example, I tried: echo C:\windows\path|sed 's|\|g' but got the following error sed: -e expression #1, char 7: unterminated `s' command My goal is to reduce the typing, so maybe I could write a program which I could call. Ideally I would type: conversionScript cd C:/windows/path and this would be equivalent to typing: cd C:\windows\path

• Change Emacs Default Coding System

  - by Saterus

  My problem stems from Emacs inserting the coding system headers into source files containing non-ascii characters: # -*- coding: utf-8 -*- My coworkers do not like these headers being checked into our repositories. I don't want them inserted into my files because Emacs automatically detects that the file should be UTF-8 regardless so there doesn't seem to be any benefit to anyone. I would like to simply set Emacs to use UTF-8 automatically for all files, yet it seems to disagree with this idea. In an effort to fix this, I've added the following to my .emacs: (prefer-coding-system 'utf-8) (setq coding-system-for-read 'utf-8) (setq coding-system-for-write 'utf-8) This does not seem to solve my problem. Emacs still inserts the coding-system headers into my files. Anyone have any ideas? EDIT: I think this problem is specifically related to ruby-mode. I still can't turn it off though.

• Socket Bind Error

  - by rantravee

  Hi, I have a test application that opens a socket , sends something through this socket and then closes it . This is done in a loop for 5-10.000 times. The thing is that after 3,4000 iterations I get an error of this type : enter code here java.net.BindException: Address already in use: connect I even set the socket to be used immediattly, but the error persists enter code here try { out_server.write(m.ToByteArray()); socket_server.setReuseAddress(true); socket_server.close(); } catch(Exception e) { e.printStackTrace(); System.out.println(i+" unable to register with the server"); } What could I do to fix this ?

• how to check if the enddate is after the startdate in a zend form

  - by murze

  I have a zend form with a start- and an endate. $form = new Zend_Form(); $form->setName($this->formName) ->setMethod('post'); $feStartdate = new Zend_Form_Element_Text('startdate'); $feEnddate = new Zend_Form_Element_Text('enddate'); $form->addElement($feStartDate) ->addElement($feEndDate) ->addElement('submit', 'submit', array('label' => 'Save')); I assume I must write a custom validator for to check this. How would this custom validator look like and how can I call it? I assume something like $feEnddate->addValidator('dateComesAfter', $feStartDate)

• Django doctests in views.py

  - by Brian M. Hunt

  The Django documentation on tests states: For a given Django application, the test runner looks for doctests in two places: The models.py file. You can define module-level doctests and/or a doctest for individual models. It's common practice to put application-level doctests in the module docstring and model-level doctests in the model docstrings. A file called tests.py in the application directory -- i.e., the directory that holds models.py. This file is a hook for any and all doctests you want to write that aren't necessarily related to models. Out of curiosity I'd like to know why Django's testrunner is limited to the doctests in models.py, but more practically I'd like to know how one could expand the testrunner's doctests to include (for example) views.py and other modules when running manage.py test. I'd be grateful for any input. Thank you. Brian

• Cleanest way to tell if 3 times are within half an hour of each other

  - by niggles

  I have 3 date / time input boxes on a form and the user cannot select any times within half an hour of each other. I've converted all values to epoch format using a Javascript implementation of strtotime, but not sure how to recursively check that any of the times are actually half an hour apart. I can hand code all checks, but it would be cleaner to write a recursive function (especially if there were theoretically more than 3 time slots). Did some Google research but no luck. Any suggestions on implementing this in Javascript or Jquery. Thanks.

• Setting column length of a Long value with JPA annotations

  - by Gearóid

  Hi, I'm performing a little database optimisation at the moment and would like to set the column lengths in my table through JPA. So far I have no problem setting the String (varchar) lengths using JPA as follows: @Column(unique=true, nullable=false, length=99) public String getEmail() { return email; } However, when I want to do the same for a column which is of type Long (bigint), it doesn't work. For example, if I write: @Id @Column(length=7) @GeneratedValue(strategy = GenerationType.AUTO) public Long getId() { return id; } The column size is still set as the default of 20. Are we able to set these lengths in JPA or am I barking up the wrong tree? Thanks, Gearoid.

• Php using unserialize() and serialize() changing values in a saved file

  - by Doodle

  I have a serialized array of values saved to a file and need to change the value of one of the variables. In the example I change the value of $two and then save the whole array back into the file with the new value. Is there a more efficient way of altering just the single value with out having to read and write the entire file/array. $data = file_get_contents('./userInfo'); $data = unserialize($data); extract($data); $two="this is a altered value"; $userData = array( 'one' => $one, 'two' => $two, 'three' => $three ); $file=fopen("../userInfo",'w'); fwrite($file, $userData); fclose($file);

• Algorithm to determine coin combinations

  - by A.J.

  I was recently faced with a prompt for a programming algorithm that I had no idea what to do for. I've never really written an algorithm before, so I'm kind of a newb at this. The problem said to write a program to determine all of the possible coin combinations for a cashier to give back as change based on coin values and number of coins. For example, there could be a currency with 4 coins: a 2 cent, 6 cent, 10 cent and 15 cent coins. How many combinations of this that equal 50 cents are there? The language I'm using is C++, although that doesn't really matter too much. edit: This is a more specific programming question, but how would I analyze a string in C++ to get the coin values? They were given in a text document like 4 2 6 10 15 50 (where the numbers in this case correspond to the example I gave)

• Can I create object names from a text file in Python 2.7?

  - by user560100

  I'm working on a game project. I've created an object, Star(Object). I want to assign the name of the variables, dynamically, from a text file. If I have a text file with: Sol Centauri Vega I want the program to create the Star(Object) with variable names from the text file. I want the process automated, because I'm looking to create hundreds of stars. I could write the code out by hand: Sol = Star(Sol) Centauri = Star(Centauri) Vega = Star(Vega) But isn't there a way to automate this? Essentially, what I eventually want is a tuple with the list of stars, as their own objects. Then, when I am doing game maintenance, I can just iterate over all the objects in the tuple.

• Use Javascript to retrieve HTML on same-domain

  - by ehfeng

  Say I have an xml document on a webserver (www.example.com/example.xml). On my main page, if I would like to retrieve that document as a string, how can I do this? I tried xmlhttprequest - maybe I'm using it wrong? It returns it as "undefined." Help? var xml_page = new XMLHttpRequest(); xml_page.open("GET", "http://www.samedomain.com/example.xml", true); if (xml_page.readyState == 4 && xml_page.status == 200) { var data = xml_page.responseText; } document.write(data);

• Is it possible to compile IronRuby code to a .NET assembly (EXE or DLL)

  - by Chris Ammerman

  My scenario consists of the following points. I have a packaged software product I am developing in C# Since it is a packaged product, the public interfaces of the assemblies need to be tightly controlled... All assemblies are strong-named Any classes that don't absolutely have to be "public" are "internal" I want to write unit tests for those "internal" classes, since they are the bulk of the code And finally.... I want to try writing the unit tests in Ruby. Since the unit tests would be external to the assembly containing the code under test, the assemblies under test would each need to have an "InternalsVisibleTo" attribute specifying the name of the unit test assembly. Which of course would mean that the Ruby unit tests would have to compile down to a .NET assembly so they can be given access in this way. Can this be done? If so, how? All I can find on the web about "compiling IronRuby" is about building the actual IronRuby runtime from source.

• Why won't asp.net create cookies in localhost?

  - by James McConnell

  Okay, this is really kinda starting to bug me. I have a simple Web project setup located at: "C:\Projects\MyTestProject\". In IIS on my machine, I have mapped a virtual directory to this location so I can run my sites locally (I understand I can run it from Visual Studio, I like this method better). I have named this virtual directory "mtp" and I access it via http://localhost/mtp/index.aspx. All this is working fine. However, whenever I try to create a cookie, it simply never gets written out? I've tried this in FF3 and IE7 and it just plain won't write the cookie out. I don't get it. I do have "127.0.0.1 localhost" in my hosts file, I can't really think of anything else I can do. Thanks for any advice. James

• Continuation monad "interface"

  - by sdcvvc

  The state monad "interface" class MonadState s m where get :: m s put :: s -> m () (+ return and bind) allows to construct any possible computation with State monad without using State constructor. For example, State $ \s -> (s+1, s-1) can be written as do s <- get put (s-1) return (s+1) Similarily, I never have to use Reader constructor, because I can create that computation using ask, return and (>>=). Precisely: Reader f == ask >>= return . f. Is it the same true for continuations - is it possible to write all instances of Cont r a using callCC (the only function in MonadCont), return and bind, and never type something like Cont (\c -> ...)?

• Is it possible to create a new T-SQL Operator using CLR Code in SQL Server?

  - by Eoin Campbell

  I have a very simple CLR Function for doing Regex Matching public static SqlBoolean RegExMatch(SqlString input, SqlString pattern) { if (input.IsNull || pattern.IsNull) return SqlBoolean.False; return Regex.IsMatch(input.Value, pattern.Value, RegexOptions.IgnoreCase); } It allows me to write a SQL Statement Like. SELECT * FROM dbo.table1 WHERE dbo.RegexMatch(column1, '[0-9][A-Z]') = 1 -- match entries in col1 like 1A, 2B etc... I'm just thinking it would be nice to reformulate that query so it could be called like SELECT * FROM dbo.table1 WHERE column1 REGEXLIKE '[0-9][A-Z]' Is it possible to create new comparison operators using CLR Code. (I'm guessing from my brief glance around the web that the answer is NO, but no harm asking)

• Inserting clobs into oracle with ODBC

  - by Carra

  I'm trying to insert a clob into Oracle. If I try this with an OdbcConnection it does not insert the data into the database. It returns 1 row affected and no errors but nothing is inserted into the database. It does work with an OracleConnection. However, using the Microsoft OracleClient makes our webservices often crash with an AccessViolationException (Attempted to read or write protected memory. This is often an indication that other memory is corrupt.). This happens a lot when we use OracleDataAdapter.Fill(dataset). So using this doesn't seem like an option. Is there any way to insert/update clobs with more then 4.000 characters from .Net with an OdbcConnection?

• java: how to get a string representation of a compressed byte array ?

  - by Guillaume

  I want to put some compressed data into a remote repository. To put data on this repository I can only use a method that take the name of the resource and its content as a String. (like data.txt + "hello world"). The repository is moking a filesystem but is not, so I can not use File directly. I want to be able to do the following: client send to server a file 'data.txt' server compress 'data.txt' into a compressed file 'data.zip' server send a string representation of data.zip to the repository repository store data.zip client download from repository data.zip and his able to open it with its favorite zip tool The problem arise at step 3 when I try to get a string representation of my compressed file. Here is a sample class, using the zip*stream and that emulate the repository showcasing my problem. The created zip file is working, but after its 'serialization' it's get corrupted. (the sample class use jakarta commons.io ) Many thanks for your help. package zip; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.util.zip.ZipEntry; import java.util.zip.ZipInputStream; import java.util.zip.ZipOutputStream; import org.apache.commons.io.FileUtils; /** * Date: May 19, 2010 - 6:13:07 PM * * @author Guillaume AME. */ public class ZipMe { public static void addOrUpdate(File zipFile, File ... files) throws IOException { File tempFile = File.createTempFile(zipFile.getName(), null); // delete it, otherwise you cannot rename your existing zip to it. tempFile.delete(); boolean renameOk = zipFile.renameTo(tempFile); if (!renameOk) { throw new RuntimeException("could not rename the file " + zipFile.getAbsolutePath() + " to " + tempFile.getAbsolutePath()); } byte[] buf = new byte[1024]; ZipInputStream zin = new ZipInputStream(new FileInputStream(tempFile)); ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFile)); ZipEntry entry = zin.getNextEntry(); while (entry != null) { String name = entry.getName(); boolean notInFiles = true; for (File f : files) { if (f.getName().equals(name)) { notInFiles = false; break; } } if (notInFiles) { // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(name)); // Transfer bytes from the ZIP file to the output file int len; while ((len = zin.read(buf)) > 0) { out.write(buf, 0, len); } } entry = zin.getNextEntry(); } // Close the streams zin.close(); // Compress the files if (files != null) { for (File file : files) { InputStream in = new FileInputStream(file); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(file.getName())); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file } tempFile.delete(); out.close(); } public static void main(String[] args) throws IOException { final String zipArchivePath = "c:/temp/archive.zip"; final String tempFilePath = "c:/temp/data.txt"; final String resultZipFile = "c:/temp/resultingArchive.zip"; File zipArchive = new File(zipArchivePath); FileUtils.touch(zipArchive); File tempFile = new File(tempFilePath); FileUtils.writeStringToFile(tempFile, "hello world"); addOrUpdate(zipArchive, tempFile); //archive.zip exists and contains a compressed data.txt that can be read using winrar //now simulate writing of the zip into a in memory cache String archiveText = FileUtils.readFileToString(zipArchive); FileUtils.writeStringToFile(new File(resultZipFile), archiveText); //resultingArchive.zip exists, contains a compressed data.txt, but it can not //be read using winrar: CRC failed in data.txt.

• How to have a function with a nullable string parameter in Go?

  - by yuku

  I'm used to Java's String where we can pass null rather than "" for special meanings, such as use a default value. In Go, string is a primitive type, so I cannot pass nil (null) to a parameter that requires a string. I could write the function using pointer type, like this: func f(s *string) so caller can call that function either as f(nil) or // not so elegant temp := "hello"; f(&temp) but the following is unfortunately not allowed: // elegant but disallowed f(&"hello"); What is the best way to have a parameter that receives either a string or nil?
