  • What is the advantage of creating an enumerable object using to_enum in Ruby?

    - by Jason
    Hi, Why would you create a proxy reference to an object in Ruby, by using the to_enum method rather than just using the object directly? I cannot think of any practical use for this, trying to understand this concept & where someone might use it, but all the examples I have seen seem very trivial. For example, why use: "hello".enum_for(:each_char).map {|c| c.succ } instead of "hello".each_char.map {|c| c.succ } I know this is a very simple example, does anyone have any real-world examples? Thanks!

  • Nested Resource - How to pass needed keys, and attribute to update?

    - by Jason B
    My nested resources are working for form_for updates, but I have a few toggles that I need to setup to change a status field. So I am using link_to, and accessing the url helper. link_to "toggle", edit_project_expense_path(@project[:id],expense_item[:id]) routes.rb resources :projects do resources :expenses end match '/submit_expense/:id' => 'expenses#submit_expense', :as => 'submit_expense' rake routes edit_project_expense GET /projects/:project_id/expenses/:id/edit(.:format) expenses#edit My question is: How can I also send along :approval_status = "1", with my link_to?

  • Issues with dynamically allocating a string array

    - by Jason Block
    Brand new to C. I am trying to dynamically allocate the array frags2 of size numberOfFrags and copy over the contents of the original array to it. I have tried numerous approaches and searching and do not understand what is going wrong here. Sizeof on the new array returns 0 instead of what I thought I malloc'd. Any help would be much appreciated! int main(int argc, const char* argv[]) { char* frags[MAX_FRAG_COUNT]; FILE* fp = fopen(argv[1], "r"); int numberOfFrags = ReadAllFragments(fp, frags, MAX_FRAG_COUNT); fclose(fp); char** frags2 = (char**)malloc(numberOfFrags * sizeof(char*)); for (int i = 0; i < numberOfFrags; i++) { frags2[i] = frags[i]; } qsort(frags2, sizeof(frags2) / sizeof(char *), sizeof(char*), cstring_cmp);

  • Order of execution and style of coding in Python

    - by Jason
    Hi guys. I am new to Python so please don't flame me if the question is too basic :) I have read that Python is executed from top - to - bottom. If this is the case, why do programs go like this: def func2(): def func1(): #call func2() def func() #call func1() if __name__ == '__main__': call func() So from what I have seen, the main function goes at last and the other functions are stacked on top of it. Am I wrong in saying this? If no, why isn't the main function or the function definitions written from top to bottom?

  • HTML5 Search Input: No Background Image in Chrome?

    - by Jason
    I have been pulling my hair out trying to get Chrome to style my search input with a background image. Firefox has no problem, but I fear it's because it treats the input as a regular text input. Is this simply not possible? Try this as a demo: <input type="search" /> ?input[type="search"] { background: transparent url(http://google.com/intl/en_ALL/images/srpr/logo1w.png) no-repeat 0 0; }?????? If it worked correctly, it should put Google's logo (or part of it) as the background image for the "Search" input. But as you will see when you look at this in Chrome, it DOES NOT WORK. Any ideas, or is this just one of HTML5's quirks? :\

  • Will a source-removal sort always return a maximal cycle?

    - by Jason Baker
    I wrote a source-removal algorithm to sort some dependencies between tables in our database, and it turns out we have a cycle. For simplicity, let's say we have tables A, B, C, and D. The edges are like this: (A, B) (B, A) (B, C) (C, D) (D, A) As you can see, there are two cycles here. One is between A and B and another is between all four of them. Will this type of sort always choke on the largest cycle? Or is that not necessarily the case?

  • Using curl to submit/retrieve a forms results

    - by Jason
    I need help in trying to use curl to post data to a page and retrieve the results after the form has been submitted. I created a simple form: <form name="test" method="post" action="form.php"> <input type="text" name="name" size="40" />e <input type="text" name="comment" size="140" /> <input type="submit" name="submit" value="submit" /> </form> In addition, I have php code to handle this form in the same page. All it does is echo back the form values. The curl that I have been using is this: $h = curl_init(); curl_setopt($h, CURLOPT_URL, "path/to/form.php"); curl_setopt($h, CURLOPT_POST, true); curl_setopt($h, CURLOPT_POSTFIELDS, array( 'name' = 'yes', 'comment' = 'no' )); curl_setopt($h, CURLOPT_HEADER, false); curl_setopt($h, CURLOPT_RETURNTRANSFER, 1); $result = curl_exec($h); When I launch the page with the curl code in it, I get the form.php page contents but it doesn't not show the variables that PHP should have echo'd when the form is submitted. would appreciate any help with this. Thanks.

  • java.awt.Desktop.open doesn’t work with PDF files?

    - by Jason S
    It looks like I cannot use Desktop.open() on PDF files regardless of location. Here's a small test program: package com.example.bugs; import java.awt.Desktop; import java.io.File; import java.io.IOException; public class DesktopOpenBug { static public void main(String[] args) { try { Desktop desktop = null; // Before more Desktop API is used, first check // whether the API is supported by this particular // virtual machine (VM) on this particular host. if (Desktop.isDesktopSupported()) { desktop = Desktop.getDesktop(); for (String path : args) { File file = new File(path); System.out.println("Opening "+file); desktop.open(file); } } } catch (IOException e) { e.printStackTrace(); } } } If I run DesktopOpenBug with arguments c:\tmp\zz1.txt c:\tmp\zz.xml c:\tmp\ss.pdf (3 files I happen to have lying around) I get this result: (the .txt and .xml files open up fine) Opening c:\tmp\zz1.txt Opening c:\tmp\zz.xml Opening c:\tmp\ss.pdf java.io.IOException: Failed to open file:/c:/tmp/ss.pdf. Error message: The parameter is incorrect. at sun.awt.windows.WDesktopPeer.ShellExecute(Unknown Source) at sun.awt.windows.WDesktopPeer.open(Unknown Source) at java.awt.Desktop.open(Unknown Source) at com.example.bugs.DesktopOpenBug.main(DesktopOpenBug.java:21) What the heck is going on? I'm running WinXP, I can type "c:\tmp\ss.pdf" at the command prompt and it opens up just fine. edit: if this is an example of Sun Java bug #6764271 please help by voting for it. What a pain. :(

  • Copying a database into a new database including structure and data

    - by Jason
    In phpMyAdmin under operations I can "Copy database to:" and select Structure and data CREATE DATABASE before copying Add AUTO_INCREMENT value I need to be able to do that without using phpMyAdmin. I know how to create the database and user. I have a source database that's a shell that I can work from so all I really need is the how to copy all the table structure and data part. (I know, the harder part) system() & exec() are not options for me which rules out mysqldump. (I think) How can I loop through each table and recreate it's structure and data? Is it just looping through the results of SHOW TABLES then for each table looping through DESCRIBE tablename Then, is there an easy way for getting the data copied?

  • Need Help With ASP.NET Custom Route

    - by Jason
    I need to create a custom route to list all the rooms in a given building. So, I want the url to look something like this: /Building/1000/Room Which would list all the rooms in Building 1000. Is this the correct mapping for the route (to call the IndexByBuilding method in RoomController)? routes.MapRoute( "RoomsByBuilding", "Building/{id}/Room", new { controller = "Room", action = "IndexByBuilding", id = "" } );

  • Trying to pass variable from 1 Function to Another to Put in Array within same Model

    - by Jason Shultz
    Ok, that sounds really confusing. What I’m trying to do is this. I’ve got a function that uploads/resizes photos to the server. It stores the paths in the DB. I need to attach the id of the business to the row of photos. Here’s what I have so far: function get_bus_id() { $userid = $this->tank_auth->get_user_id(); $this->db->select('b.id'); $this->db->from ('business AS b'); $this->db->where ('b.userid', $userid); $query = $this->db->get(); if ($query->num_rows() > 0) { return $query->result_array(); } That get’s the id of the business. Then, I have my upload function which is below: /* Uploads images to the site and adds to the database. */ function do_upload() { $config = array( 'allowed_types' => 'jpg|jpeg|gif|png', 'upload_path' => $this->gallery_path, 'max_size' => 2000 ); $this->load->library('upload', $config); $this->upload->do_upload(); $image_data = $this->upload->data(); $config = array( 'source_image' => $image_data['full_path'], 'new_image' => $this->gallery_path . '/thumbs', 'maintain_ratio' => true, 'width' => 150, 'height' => 100 ); $this->load->library('image_lib', $config); $this->image_lib->resize(); $upload = $this->upload->data(); $bus_id = $this->get_bus_id(); $data = array( 'userid' => $this->tank_auth->get_user_id(), 'thumb' => $this->gallery_path . '/thumbs/' . $upload['file_name'], 'fullsize' => $upload['full_path'], 'busid'=> $bus_id['query'], ); echo var_dump($bus_id); $this->db->insert('photos', $data); } The problem I’m getting is the following: A PHP Error was encountered Severity: Notice Message: Undefined index: id Filename: models/gallery_model.php Line Number: 48 I’ve tried all sorts of ways to get the value over, but my limited knowledge keeps getting in the way. Any help would be really appreciated.

  • python: list manipulation

    - by Jason S
    I have a list L of objects (for what it's worth this is in scons). I would like to create two lists L1 and L2 where L1 is L with an item I1 appended, and L2 is L with an item I2 appended. I would use append but that modifies the original list. How can I do this in Python? (sorry for the beginner question, I don't use the language much, just for scons)

  • jQuery - How to Prevent Animation Queue Buildup with Double Animations?

    - by Jason
    Hello, I was taking a look at this tutorial here to prevent animation buildups: http://www.learningjquery.com/2009/01/quick-tip-prevent-animation-queue-buildup My situation: I am doing a double animation like this below, and would like the prevent the animation build up. Since I have 2 animations going, it seems it ignores the .stop(). What can be done to prevent this? I have tried .stop() on both .animate and if I do that it stops animating... $(document).ready(function() { $('#element').hover(function() { $(this).stop() .animate( { left: 200 }, { duration: 'slow', }) .animate( { top: 200 }, { duration: 'slow', }); } , function() { $(this).stop() .animate( { left: 0 }, { duration: 'slow', }) .animate( { top: 0 }, { duration: 'slow', }); }); }); Any help will be greatly aprecaited!!

Ideas? thanks

  • Image equivalent of ActionLink in ASP.NET MVC

    - by Jason Whitehorn
    In ASP.NET MVC is there an equivalent of the Html.ActionLink helper for Img tags? I have a controller action that outputs a dynamically generated JPEG and I wanted to use the same Lambda expressions to link to it as I do HREFs using ActionLink. Alternatively, a helper that just gives the URL to a route (again specified using Lambdas) would also be acceptable. EDIT: I had originally specified that I was using Preview 5, however I see that a Beta has been released. So all-in-all the version number was an unneeded piece of info as I may be upgrading soon :-)

  • Saving Email/Password to Keychain in iOS

    - by Jason
    I'm very new to iOS development so forgive me if this is a newbie question. I have a simple authentication mechanism for my app that takes a user's email address and password. I also have a switch that says 'Remember me'. If the user toggles that switch on, I'd like to preserve their email/password so those fields can be auto-populated in the future. I've gotten this to work with saving to a plist file but I know that's not the best idea since the password is unencrypted. I found some sample code for saving to the keychain, but to be honest, I'm a little lost. For the function below, I'm not sure how to call it and how to modify it to save the email address as well. I'm guessing to call it would be: saveString(@"passwordgoeshere"); Thank you for any help!!! + (void)saveString:(NSString *)inputString forKey:(NSString *)account { NSAssert(account != nil, @"Invalid account"); NSAssert(inputString != nil, @"Invalid string"); NSMutableDictionary *query = [NSMutableDictionary dictionary]; [query setObject:(id)kSecClassGenericPassword forKey:(id)kSecClass]; [query setObject:account forKey:(id)kSecAttrAccount]; [query setObject:(id)kSecAttrAccessibleWhenUnlocked forKey:(id)kSecAttrAccessible]; OSStatus error = SecItemCopyMatching((CFDictionaryRef)query, NULL); if (error == errSecSuccess) { // do update NSDictionary *attributesToUpdate = [NSDictionary dictionaryWithObject:[inputString dataUsingEncoding:NSUTF8StringEncoding] forKey:(id)kSecValueData]; error = SecItemUpdate((CFDictionaryRef)query, (CFDictionaryRef)attributesToUpdate); NSAssert1(error == errSecSuccess, @"SecItemUpdate failed: %d", error); } else if (error == errSecItemNotFound) { // do add [query setObject:[inputString dataUsingEncoding:NSUTF8StringEncoding] forKey:(id)kSecValueData]; error = SecItemAdd((CFDictionaryRef)query, NULL); NSAssert1(error == errSecSuccess, @"SecItemAdd failed: %d", error); } else { NSAssert1(NO, @"SecItemCopyMatching failed: %d", error); } }

  • Is putting the javascript before the closing body tag okay on an asp.net website?

    - by Jason Weber
    I pretty much stated what I have to ask. But is taking all of your external .js files and putting them before the closing body tag on your master pages okay on an asp.net website? I'm just going off of what yslow and google speed have been showing. I can't combine these javascripts, so I'm trying to load them "after page load", but doing so makes them useless; some of my jquery things don't work. I moved my .js files above the opening body tag, and they work. What am I doing wrong? And what could I do to load my .js files after page load? Thanks for any advice anybody can offer!

  • How does one receive and post text messages on a website, a la Twitter?

    - by Jason
    I've looked around at pretty much all the SMS posts here on SO and the best answer I've come up with so far is ZeepMobile. The only problem is, they're "in beta" and aren't readily accepting users. Is there a workaround for this, maybe receiving an email via text (kind of like how TwitPic does it?) somehow and parsing it? Basically all I want to do is have people text the site so that their message posts... I don't need to send any messages (actually I would prefer not to). Pretty much the same functionality as Twitter (same functionality, but no I'm not building a Twitter-esque service because I am not crazy). PS this will be a VB.NET ASP.NET 3.5 solution. Anyone have any ideas? Thanks

  • scons environment setup

    - by Jason S
    Is there a way to tell scons to use a particular file to setup the default environment? I am using TI DSPs and the compiler is something different than cc; I'd like to have one "environment file" that defines where the compiler is, and what the default flags are, and then be able to use this for several projects. Any suggestions?

  • Managing My Database in Source Control

    - by Jason
    As I am working with a new database project (within VS2008), and as I have never developed a database from scratch, I immediately began looking into how to manage a database within source control (in this case, Subversion). I found some information on SO, including this post: Keeping development databases in multiple environments in sync. One of the answers in particular pointed to a number of a links, all of which had good, useful information. I was reading a series of posts by K. Scott Allen which describe how he manages database change. From my reading (and please pardon the noobishness of my question), it seems as though the database itself is never checked into a repository. Rather, scripts that can build the database, along with test data (which is also populated from scripts) is checked into the repository. Ultimately, this means that, when a developer is testing his or her app, these scripts, which are part of the build process, are run. This ensures that the database is up-to-date, but is also run locally from every developer's machine. This makes sense to me (if I am indeed reading that correctly). However, if I am missing something, I would appreciate correction or additional guidance. In addition, another question I wanted to ask - does this also mean that I should NOT check in the mdf or ldf files that are created from Visual Studio? Thanks for any help and additional insight. Always appreciated.
