• Finding missing files by checksum

  - by grw

  Hi there, I'm doing a large data migration between two file systems (let's call them F1 and F2) on a Linux system which will necessarily involve copying the data verbatim into a differently-structured hierarchy on F2 and changing the file names. I'd like to write a script to generate a list of files which are in F1 but not in F2, i.e. the ones which weren't copied by the migration script into the new hierarchy, so that I can go back and migrate them manually. Unfortunately for reasons not worth going into, the migration script can't be modified to list files that it doesn't migrate. My question differs from this previously answered one because of the fact that I cannot rely on filenames as a comparison. I know the basic outline of the process would be: Generate a list of checksums for all files, recursing through F1 Do the same for F2 Compare the lists and generate a negative intersection of the checksums, ignoring the file names, to find files which are in F1 but not in F2. I'm kind of stuck getting past that stage, so I'd appreciate any pointers on which tools to use. I think I need to use the 'comm' command to compare the list of file checksums, but since md5sum, sha512sum and the like put the file name next to the checksum, I can't see a way to get it to bring me a useful comparison. Maybe awk is the way to go? I'm using Red Hat Enterprise Linux 5.x. Thanks.

• Contrary to Python 3.1 Docs, hash(obj) != id(obj). So which is correct?

  - by Don O'Donnell

  The following is from the Python v3.1.2 documentation: From The Python Language Reference Section 3.3.1 Basic Customization: object.__hash__(self) ... User-defined classes have __eq__() and __hash__() methods by default; with them, all objects compare unequal (except with themselves) and x.__hash__() returns id(x). From The Glossary: hashable ... Objects which are instances of user-defined classes are hashable by default; they all compare unequal, and their hash value is their id(). This is true up through version 2.6.5: Python 2.6.5 (r265:79096, Mar 19 2010 21:48:26) ... ... >>> class C(object): pass ... >>> c = C() >>> id(c) 11335856 >>> hash(c) 11335856 But in version 3.1.2: Python 3.1.2 (r312:79149, Mar 21 2010, 00:41:52) ... ... >>> class C: pass ... >>> c = C() >>> id(c) 11893680 >>> hash(c) 743355 So which is it? Should I report a documentation bug or a program bug? And if it's a documentation bug, and the default hash() value for a user class instance is no longer the same as the id() value, then it would be interesting to know what it is or how it is calculated, and why it was changed in version 3.

• can I add properties to a typo3 extbase domain model object?

  - by The Newbie Qs

  I want to store a username in a coupon object, each coupon object already has the uid of the user who created it. I can loop over the coupon objects and read the associated usernames from fe_users but how then will I save those usernames into the coupons so when they are passed to the template the usernames can be read like so coupon.username, or in some other easy way so each username will appear on the page with the right coupon as they are all printed out in a table? If I was doing basic php instead of typo3 i would just define a query but what is the typo3 v4.5 way? My code so far - which dies on the line where I try to assign the new property --creatorname -- to the $coup object. public function listAction() { $coupons = $this->couponRepository->findAll(); // @var Tx_Extbase_Domain_Repository_FrontendUserRepository $userRepository */ $userRepository = $this->objectManager->get("Tx_Extbase_Domain_Repository_FrontendUserRepository"); foreach ($coupons as $coup) { echo '<br />test '.$coup->getCreator(); echo '<br />count = '.$userRepository->countAll().'<br />'; $newObject = $userRepository->findByUid( intval($coup->getCreator())); //var_dump($newObject); var_dump($coup); echo '<br />getUsername '.$newObject->getUsername() ; $coup['creatorname'] = $newObject->getUsername(); echo '<br />creatorname '.$coup['creatorname'] ; } $this->view->assign('coupons', $coupons); }

• Best way reading from dirty excel sheets

  - by Ten Ton Gorilla

  I have to manipulate some Excel documents with C#. It's a batch process with no user interaction. It's going to parse data into a database, then output nice reports. The data is very dirty and cannot be ready using ADO. The data is nowhere near a nice table format. Best is defined as the most stable(updates less likely to break)/ clear(succinct) code. Fast doesn't matter. If it runs in less than 8 hours I'm fine. I have the logic to find the data worked out. All I need to make it run is basic cell navigation and getvalue type functions. Give me X cell value as string, if it matches Y value with levenshtein distance < 3, then give me Z cell value. My question is, what is the best way to dig into the excel? VSTO? Excel Objects Library? Third Option I'm not aware of?

• SWIG: From Plain C++ to working Wrapper

  - by duckworthd

  Hi everyone. I've been trying to create a SWIG wrapper for this tiny little C++ class for the better part of 3 hours with no success, so I was hoping one of you out there could lend me a small hand. I have the following class: #include <stdio.h> class Example { public: Example(); ~Example(); int test(); }; #include "example.h" Along with the implementation: Example::Example() { printf("Example constructor called\n"); } Example::~Example() { printf("Example destructor called\n"); } int Example::test() { printf("Holy shit, I work!\n"); return 42; } I've read through the introduction page ( www.swig.org/Doc1.3/Java.html ) a few times without gaining a whole lot of insight into the situation. My steps were Create an example.i file Compile original alongside example_wrap.cxx (no linking) link resulting object files together Create a little java test file (see below) javac all .java files there and run Well steps 4 and 5 have created a host of problems for me, starting with the basic ( library 'example' not found due to not being in java's path ) to the weird ( library not found even unless LD_LIBRARY_PATH is set to something, even if it's nothing at all). I've included my little testing code below public class test2 { static { String libpath = System.getProperty("java.library.path"); String currentDir = System.getProperty("user.dir"); System.setProperty("java.library.path", currentDir + ":" + libpath); System.out.println(System.getProperty("java.library.path")); System.loadLibrary("example"); } public static void main(String[] args){ System.out.println("It loads!"); } } Well, if anyone has navigated these murky waters of wrapping, I could not be happier than if you could light the way, particularly if you could provide the example.i and bash commands to go along with it.

• Browser Issue: Charts are not rendered on IE8

  - by Rachel

  We have inhouse library which uses canvas for displaying charts in my application. And dojo as scripting language.Everything is fine, but my charts are not appearing in IE8. I google about this, and found that there is some VML issue in IE8. I found this: var printChart = function(time, freq){ if (!document.namespaces['g_vml_']) { document.namespaces.add('g_vml_', 'urn:schemas-microsoft-com:vml', '#default#VML'); } if (!document.namespaces['g_o_']) { document.namespaces.add('g_o_', 'urn:schemas-microsoft-com:office:office', '#default#VML'); } if (freq === undefined) { this.freq = "1mi"; } if (time === undefined) { this.time = "1dy"; } self.reload(); } Now I was trying to add this in my DOJO code and that is creating problem. As when I do document.namespace I get firebug error 'document.namespaces is undefined'. Q: How can we fix this, are the any better alternative approaches for the same, basic problem am having is browser related, charts are rendered properly on other browsers but not on IE8, any suggestions ? Update: What are ways to deal with such cross browser issue ?

• Which is the best license for my Open Source project?

  - by coderex

  I am a web developer, and I don't have enough knowledge about software licenses. I wish to publish some of my works, and I need to select licenses for them. My software product is free of cost. But I have some restrictions on the distribution/modification of the code. It's free of cost (but donations are acceptable ;-)). The source code is freely available. You can use, customize or edit/remove code (as long as the basic nature of the software is not changed). You don't have any permission to change the product name. There are some libraries and classes which are in a folder caller "myname". You don't have the permission to rename "myname". You can contribute any additions or modifications to my project, to the original source repository (the contributors name/email/site link will be listed on the credit file). You can't remove the original author's name from the license. You can put the license file or license code anywhere in the project file or folder. You can redistribute this code as free or commercial software. :) Do you think all these restrictions are valid? Given these restrictions, which license should I use? Edit 1:- My main intention is to make the product more popular with free source code while ensuring the original author is not ignored. The product is open. Edit 2:- Thank you all, the above points are because of my lack of knowledge of license terms. You can help me to correct or remove some of the above points. What I'm basically looking for is in my Edit 1.

• IE7 & 8 not fireing jQuery click events for elements appended inside a table

  - by Keith

  I have an IE bug that I'm not sure how to fix. Using jQuery I'm dynamically moving a menu to appear on an element on mouseover. My code (simplified) looks something like this: $j = jQuery.noConflict(); $j(document).ready(function() { //do something on the menu clicks $j('div.ico').click(function() { alert($j(this).parent().html()); }); setUpActions('#tableId', '#menuId'); }); //on mouseover set up the actions menu to appear on mouseover function setUpActions(tableSelector, menuSelector) { $j(tableSelector + ' div.test').mouseover(function() { //note that append will move the underlying //DOM element with all events from it's old //parent to the end of this one. $j(this).append($j(menuSelector).show()); }); } This menu doesn't seem to register events correctly for the menu after it's been moved in IE7, IE8 and IE8-as-IE7 (yeah MS, that's really a 'new rendering engine' in IE8, we all believe you). It works as expected in everything else. You can see the behaviour in a basic demo here. In the demo you can see two examples of the issue: The image behind the buttons should change on hover (done with a CSS :hover selector). It works on the first mouseover but then persists. The click event doesn’t fire – however with the dev tools you can manually call it and it is still subscribed. You can see (2) in IE8's dev tools: Open page in IE8 Open dev tools Select "Script" tab and "Console" sub-tab Type: $j('#testFloat div.ico:first').click() to manually call any subscribed events There will be an alert on the page This means that I'm not losing the event subscriptions, they're still there, IE's just not calling them when I click. Does anyone know why this bug occurs (other than just because of IE's venerable engine)? Is there a workaround? Could it be something that I'm doing wrong that just happens to work as expected in everything else?

• cakephp hasMany through and multiselect form

  - by Zoran Kalinic

  I'm using cakephp 2.2.2 and I have a problem with the editing view Models and relationships are: Person hasMany OrganizationPerson Organization hasMany OrganizationPerson OrganizationPerson belongs to Person,Organization A basic hasMany through relationship as found within cake documentation. Tables are: people (id,...) organizations (id,...) organization_people (id, person_id,organization_id,...) In the person add and edit forms there is a select box allowing a user to select multiple organization. The problem I have is, when a user edits an existing person, the associated organizations aren't pre-selected. Here is the code in the PeopleController: $organizations = $this->Person->OrganizationPerson->Organization->find('list'); $this->set(compact('organizations')); Related part of the code in the People/edit code looks like: $this->Form->input('OrganizationPerson.organization_id', array('multiple' => true, 'empty' => false)); This will populate the select field, but it does not pre-select it with the Person's associated organizations. Format and content of the $this-data: Array ( [Person] => Array ( [id] => 1 ... ) [OrganizationPerson] => Array ( [0] => Array ( [id] => 1 [person_id] => 1 [organization_id] => 1 ... ) [1] => Array ( [id] => 2 [person_id] => 1 [organization_id] => 2 ... ) ) ) What I have to add/change in the code to get pre-selected organizations? Thanks in advance!

• Form iteration function not working properly

  - by Moses

  My function is supposed to iterate all forms in the document, and bind an onclick function to each 'calculate' element int he form. The problem is, the function that executes on any of the click events executes in the context of the the last i in the loop. Here is the JavaScript that I'm using: window.onload = function(){ calculateSavings(); } function calculateSavings(){ for (i = 0; i < document.forms.length; i++) { var e = document.forms[i]; e.calculate.onclick = function() { var hours = e.hours.value; var rate = e.rate.value; alert(hours * rate); } } } And here is the HTML it is attached to: <!doctype html> <html> <body> <form> <label for="hours">Hours: </label><input type="text" id="hours" name="hours"> <label for="rate">Rate: </label><input type="text" id="rate" name="rate"> <input type="button" name="calculate" value="Calculate"> <div id="savings"></div> </form> <form> <label for="hours">Hours: </label><input type="text" id="hours" name="hours"> <label for="rate">Rate: </label><input type="text" id="rate" name="rate"> <input type="button" name="calculate" value="Calculate"> <div id="savings"></div> </form> </body> </html> I'm sure this is a really basic question but the solution is completely eluding me at this point.

• My python program always brings down my internet connection after several hours running, how do I debug and fix this problem?

  - by Shane

  I'm writing a python script checking/monitoring several server/websites status(response time and similar stuff), it's a GUI program and I use separate thread to check different server/website, and the basic structure of each thread is using an infinite while loop to request that site every random time period(15 to 30 seconds), once there's changes in website/server each thread will start a new thread to do a thorough check(requesting more pages and similar stuff). The problem is, my internet connection always got blocked/jammed/messed up after several hours running of this script, the situation is, from my script side I got urlopen error timed out each time it's requesting a page, and from my FireFox browser side I cannot open any site. But the weird thing is, the moment I close my script my Internet connection got back on immediately which means now I can surf any site through my browser, so it must be the script causing all the problem. I've checked the program carefully and even use del to delete any connection once it's used, still get the same problem. I only use urllib2, urllib, mechanize to do network requests. Anybody knows why such thing happens? How do I debug this problem? Is there a tool or something to check my network status once such situation occurs? It's really bugging me for a while... By the way I'm behind a VPN, does it have something to do with this problem? Although I don't think so because my network always get back on once the script closed, and the VPN connection never drops(as it appears) during the whole process.

• Howto: Access a second related model in a nested attribute builder block

  - by Joe Cairns

  I have a basic has_many through relationship: class Foo < ActiveRecord::Base has_many :bars, :dependent => :destroy has_many :wtfs :through => :bars accepts_nested_attributes_for :bars, :wtfs end On my crud forms I have a builder block for the wtf, but I need the label to come from the bar (an attribute called label for instance).

• How to achieve interaction between GUI class with logic class

  - by volting

  Im new to GUI programming, and haven't done much OOP. Im working on a basic calculator app to help me learn GUI design and to brush up on OOP. I understand that anything GUI related should be kept seperate from the logic, but Im unsure how to implement interaction between logic an GUI classes when needed i.e. basically passing variables back and forth... Im using TKinter and when I pass a tkinter variable to my logic it only seems to hold the string PY_VAR0. def on_equal_btn_click(self): self.entryVariable.set(self.entryVariable.get() + "=") calculator = Calc(self.entryVariable) self.entryVariable.set(calculator.calculate()) Im sure that im probably doing something fundamentally wrong and probabaly really stupid, I spent a considerable amount of time experimenting (and searching for answers online) but Im getting no where. Any help would be appreciated.

• Should I use early returns in C#?

  - by Bobby

  I've learned Visual Basic and was always taught to keep the flow of the program without interruptions, like Goto, Exit and Return. Using nested ifs instead of one return statement seems very natural to me. Now that I'm partly migrating towards C#, I wonder what the best practice is for C-like languages. I've been working on a C# project for some time, and of course discover more code of ExampleB and it's hurting my mind somehow. But what is the best practice for this, what is more often used and are there any reasons against one of the styles? public void ExampleA() { if (a != b) { if (a != c) { bool foundIt; for (int i = 0; i < d.Count && !foundIt; i++) { if (element == f) foundIt = true; } } } } public void ExampleB() { if (a == b) return; if (a == c) return; foreach (object element in d) { if (element == f) break; } }

• How do I distribute my slightly customized Linux in VirtualBox?

  - by goodrone

  Suppose I've got some Arch Linux installation which I'd like to distribute among students with (sometimes very) basic Linux knowledge to make them able to compile C programs in an environment very similar to that in the university. (Things like Cygwin or MinGW seem to be inappropriate here.) I also choose VirtualBox as a holder for the virtual system. The question is: how do I distribute it? I mean: installing VirtualBox on the target machine (if not still installed) uncompressing and copying my image file (.VDI) registering the image (so that VirtualBox could see it when launched) configuring the guest system in VirtualBox (network, memory, etc.) optionally installing PuTTY to simplify interfacing with the guest Linux Should I create an installer? Which one? Or just write some .BAT-scripts? (Target host system is Windows, mostly XP and Vista.) I definately don't want to have a webpage with screen shot explaining where to click and what to press, because it's boring. Additionaly, what will be the best (the most user-friendly) way to configure network when the guest Linux system is run for the first time?

• Why does mobile first responsive design tend to not use max-width queries alongside the min-width queries?

  - by Sam

  First off, I understand the basic principles behind mobile first responsive web design, and totally agree with them. But one thing I don't understand: In my experience, not all styles for small screens can be used for the larger version of a website. For example, usually smaller versions tend to have larger clickable areas, hamburger navigation, etc. So I sometimes have to override these specific styles, aside from just progressively enhancing the base styles. So I was wondering: why is max-width rarely mentioned (or used) in the context of mobile-first responsive web design? Because it looks like it could be used to isolate styles for smaller screens that are not useful for larger screens, and would thus prevent unnecessary duplication of code. A quote which mentions min-width as typically mobile-first, but not max-width: Mobile first, from a coding perspective, means that your base style is typically a single-column, fully-fluid layout. You use @media (min-width: whatever) to add a grid-based layout on top of that. from: http://gomakethings.com/mobile-first-and-internet-explorer/ EDIT: So to be more specific: I was wondering if there is a reason to exclude max-width from a mobile-first responsive design (as it seems like it can be useful for writing your css as DRY as possible, as some styles for small screens will not be used for bigger screens).

• Segmentation Fault when trying to push a string to the back of a list.

  - by user308012

  I am trying to write a logger class for my C++ calculator, but I'm experiencing a problem while trying to push a string into a list. I have tried researching this issue and have found some information on this, but nothing that seems to help with my problem. I am using a rather basic C++ compiler, with little debugging utilities and I've not used C++ in quite some time (even then it was only a small amount). My code: #ifndef _LOGGER_H_ #define _LOGGER_H_ #include <iostream> #include <list> #include <string> using std::cout; using std::cin; using std::endl; using std::list; using std::string; class Logger { private: list<string> *mEntries; public: Logger() { // Initialize the entries list mEntries = new list<string>(); } ~Logger() { // Release the list mEntries->clear(); delete mEntries; } // Public Methods void WriteEntry(string entry) { // *** BELOW LINE IS MARKED WITH THE ERROR *** mEntries->push_back(string(entryData)); } void DisplayEntries() { cout << endl << "**********************" << endl << "* Logger Entries *" << endl << "**********************" << endl << endl; for(list<string>::iterator it = mEntries->begin(); it != mEntries->end(); it++) { cout << *it << endl; } } }; #endif I am calling the WriteEntry method by simply passing in a string, like so: mLogger->WriteEntry("Testing"); Any advice on this would be greatly appreciated.

• GWT with JPA - no persistence provider...

  - by meliniak

  GWT with JPA There are two projects in my eclipse workspace, let's name them: -JPAProject -GWTProject JPAProject contains JPA configuration stuff (persistence.xml, entity classes and so on). GWTProject is an examplary GWT project (taken from official GWT tutorial). Both projects work fine alone. That is, I can create EMF (EntityManagerFactory) in JPAProject and get entities from the database. GWTProject works fine too, I can run it, fill the field text in the browser and get the response. My goal is to call JPAProject from GWTProject to get entities. But the problem is that when calling DAO, I get the following exception: [WARN] Server class 'com.emergit.service.dao.profile.ProfileDaoService' could not be found in the web app, but was found on the system classpath [WARN] Adding classpath entry 'file:/home/maliniak/workspace/emergit/build/classes/' to the web app classpath for this session [WARN] /gwttest/greet javax.persistence.PersistenceException: No Persistence provider for EntityManager named emergitPU at javax.persistence.Persistence.createEntityManagerFactory(Unknown Source) at javax.persistence.Persistence.createEntityManagerFactory(Unknown Source) at com.emergit.service.dao.profile.JpaProfileDaoService.<init>(JpaProfileDaoService.java:19) at pl.maliniak.server.GreetingServiceImpl.<init>(GreetingServiceImpl.java:21) . . . at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:380) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:395) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:488) [ERROR] 500 - POST /gwttest/greet (127.0.0.1) 3812 bytes I guess that the warnings at the beginning can be omitted for now. Do you have any ideas? I guess I am missing some basic point. All hints are highly apprecieable.

• What's the most trivial function that would benfit from being computed on a GPU?

  - by hanDerPeder

  Hi. I'm just starting out learning OpenCL. I'm trying to get a feel for what performance gains to expect when moving functions/algorithms to the GPU. The most basic kernel given in most tutorials is a kernel that takes two arrays of numbers and sums the value at the corresponding indexes and adds them to a third array, like so: __kernel void add(__global float *a, __global float *b, __global float *answer) { int gid = get_global_id(0); answer[gid] = a[gid] + b[gid]; } __kernel void sub(__global float* n, __global float* answer) { int gid = get_global_id(0); answer[gid] = n[gid] - 2; } __kernel void ranksort(__global const float *a, __global float *answer) { int gid = get_global_id(0); int gSize = get_global_size(0); int x = 0; for(int i = 0; i < gSize; i++){ if(a[gid] > a[i]) x++; } answer[x] = a[gid]; } I am assuming that you could never justify computing this on the GPU, the memory transfer would out weight the time it would take computing this on the CPU by magnitudes (I might be wrong about this, hence this question). What I am wondering is what would be the most trivial example where you would expect significant speedup when using a OpenCL kernel instead of the CPU?

• Can knowing C actually hurt the code you write in higher level languages?

  - by Jurily

  The question seems settled, beaten to death even. Smart people have said smart things on the subject. To be a really good programmer, you need to know C. Or do you? I was enlightened twice this week. The first one made me realize that my assumptions don't go further than my knowledge behind them, and given the complexity of software running on my machine, that's almost non-existent. But what really drove it home was this Slashdot comment: The end result is that I notice the many naive ways in which traditional C "bare metal" programmers assume that higher level languages are implemented. They make bad "optimization" decisions in projects they influence, because they have no idea how a compiler works or how different a good runtime system may be from the naive macro-assembler model they understand. Then it hit me: C is just one more abstraction, like all others. Even the CPU itself is only an abstraction! I've just never seen it break, because I don't have the tools to measure it. I'm confused. Has my mind been mutilated beyond recovery, like Dijkstra said about BASIC? Am I living in a constant state of premature optimization? Is there hope for me, now that I realized I know nothing about anything? Is there anything to know, even? And why is it so fascinating, that everything I've written in the last five years might have been fundamentally wrong? To sum it up: is there any value in knowing more than the API docs tell me? EDIT: Made CW. Of course this also means now you must post examples of the interpreter/runtime optimizing better than we do :)

I am using Zend, and I have the following code... //Create validators $formMustBeEmail = new Zend_Validate_EmailAddress(); $formMustBeEmail->setMessage(array( Zend_Validate_EmailAddress::INVALID => "1. Invalid type given, value should be a string", Zend_Validate_EmailAddress::INVALID_FORMAT => "2. '%value%' is no valid email address in the basic format local-part@hostname", Zend_Validate_EmailAddress::INVALID_HOSTNAME => "3. '%hostname%' is no valid hostname for email address '%value%'", Zend_Validate_EmailAddress::INVALID_MX_RECORD => "4. '%hostname%' does not appear to have a valid MX record for the email address '%value%'", Zend_Validate_EmailAddress::INVALID_SEGMENT => "5. '%hostname%' is not in a routable network segment. The email address '%value%' should not be resolved from public network.", Zend_Validate_EmailAddress::DOT_ATOM => "6. '%localPart%' can not be matched against dot-atom format", Zend_Validate_EmailAddress::QUOTED_STRING => "7. '%localPart%' can not be matched against quoted-string format", Zend_Validate_EmailAddress::INVALID_LOCAL_PART => "8. '%localPart%' is no valid local part for email address '%value%'", Zend_Validate_EmailAddress::LENGTH_EXCEEDED => "9. '%value%' exceeds the allowed length", Then I make the form... $this->addElement('text', 'email'); $emailElement = $this->getElement('email'); $emailElement ->setLabel('Emailadres') ->setOrder(1) ->setRequired(true) ->addValidator($formMustBeTest) ->addValidator($formMustBeEmail) ->addFilter(new Zend_Filter_StripTags()); But it doesn't work. I still get the normal errors made by Zend. Can anyone see what I am doing wrong? Tnx in advanced...

• Hide All But First Matching Element

  - by Batfan

  I am using jquery to sort through multiple paragraphs. Currently I have it set to show only paragraphs that start with a current letter. But now, I would like to consolidate further. If the text between the paragraph tags has multiple instances, I would like all but the first hidden. This is what I have so far but, it is not working. var letter = '<?php echo(strlen($_GET['letter']) == 1) ? $_GET['letter'] : ''; ?>' function finish(){ jQuery('p').each(function(){ if(jQuery(this).text().substr(0,1).toUpperCase() == letter){ jQuery(this).addClass('current-series'); jQuery(this).html(letter + '<span class="hidden">'+jQuery(this).text().slice(1)+ '</span>'); } else{ jQuery(this).hide();} }) } Update: Sorry guys, I know this is kind of hard to explain. Here's a basic example: The selected letter is B The values returned are: Ball Ball Ball Boy Brain Bat Bat Each of these values is in a paragraph tag. Is there a way to consolidate to this? Ball Boy Brain Bat

• Adding date to multiple fields via datepicker

  - by Andy

  i have a form in drupal with jquery based date module. there are multiple fields with date picker enabled. i want to set the value of all of them (they all have class .date-popup-init) to the value of the first field (#edit-field, the 'from' date) when that field is set. my code so far: <script type="text/javascript"> var DatePicked = function() { var firstdate = $("#edit-field"); var updater = firstdate.datepicker("getDate"); $(".date-popup-init").each(function(){ $(this).datepicker("setDate", updater); }); } $(function() { $("#edit-field").datepicker({ onSelect: DatePicked }); }); </script> this seems to randomly work; it sets the date of some fields to the value of #edit-field, seemingly different fields each time. also, the form adds more datepicker-enabled fields via ajax. is there any way to ensure that all these new fields, when they load, pick up the value of #edit-field as well? disclaimer: last night was my first attempt at javascript of any kind. i have a basic idea now. the above was cobbled through countless google examples.

• Linq Select: Using a value from a list if available

  - by musefan

  I am going to use some basic stripped down examples to illustrate my problem. I have a class: class Item { int ID; bool Selected; } Now lets say I have two lists of the Item class: List<Item> ListA = GetListA(); List<Item> ListB = GetListB(); Now I want to create a third list that has all the items from ListB. The important thing is that if a match (same ID) if found in ListA then I want to use that Selected value, otherwise I want to keep the Selected value of the item that is in ListB. I am creating the third list as follows: List<Item> ListC = from item in ListB select new Item { ID = item.ID, Selected = item.Selected// <-- should use value form ListA if available }; Important: I don't want to seem ignorant, but I do not want to change the way ListC is created. By that I mean I want to use the "linq select" method, and I want to use a "one liner" that assigns the Selected value... I know there are other ways to create the list which will work just fine, but then I won't learn anything new. I have tried a couple of things so far... I know this will work, but I don't want to query ListA twice: Selected = ListA.Any(x => x.ID == item.ID) ? ListA.First(x => x.ID == item.ID).Selected : item.Selected and I also tried using DeafultIfEmpty but I don't think that is the right think for this situation... because it didn't work, and it seems it is more use if ListA was empty (which I don't care about)
