• Is bundler ready for prime time?

  - by schof

  I'm considering using bundler for deploying a Spree app on Heroku. My question is, is bundler ready for prime time? I know there are some rough edges but I guess I'd like to know more about what the current limitations are and figure out if this is an option for us. Specifically, I'd like to do the git repository stuff git "git://github.com/indirect/rails3-generators.git" gem "rails3-generator Does anyone want to encourage/discourage me from this course of action? Anybody have experience with this on Heroku in particular?

• What C#/SQL Server feature did someone show you that made you say Wow!

  - by Randy Minder

  It's late Friday afternoon, and my mind is checking out for the week. So I thought I'd ask a light-hearted, interesting, question. Yesterday a co-worker showed me how he managed to save quite a bit of code and improve code reuse through the use of an anonymous delegate and the use of the Action function. My first thought was, "Wow, I had no idea you could do that!". I'm curious what sort of things someone showed you, either in c# or SQL Server, that made you stop and think, "Wow!". Randy

  - by pierr

  Hi, I have a shared library libtest.so which will be loaded into the the main program using dlopen. Function test() reside in libtest.so and will be called in the main program through dlsym. Is there any way I could set up a break point on test? Please note that the main programm has not been linked to libtest.so during linking time. Otherwise , I should be able to set the break point although it is a pending action. In my case, when I do b test, gdb will tell me Function "test" not defined.

• Copying one form's values to another form using JQuery

  - by rsturim

  I have a "shipping" form that I want to offer users the ability to copy their input values over to their "billing" form by simply checking a checkbox. I've coded up a solution that works -- but, I'm sort of new to jQuery and wanted some criticism on how I went about achieving this. Is this well done -- any refactorings you'd recommend? Any advice would be much appreciated! The Script <script type="text/javascript"> $(function() { $("#copy").click(function() { if($(this).is(":checked")){ var $allShippingInputs = $(":input:not(input[type=submit])", "form#shipping"); $allShippingInputs.each(function() { var billingInput = "#" + this.name.replace("ship", "bill"); $(billingInput).val($(this).val()); }) //console.log("checked"); } else { $(':input','#billing') .not(':button, :submit, :reset, :hidden') .val('') .removeAttr('checked') .removeAttr('selected'); //console.log("not checked") } }); }); </script> The Form <div> <form action="" method="get" name="shipping" id="shipping"> <fieldset> <legend>Shipping</legend> <ul> <li> <label for="ship_first_name">First Name:</label> <input type="text" name="ship_first_name" id="ship_first_name" value="John" size="" /> </li> <li> <label for="ship_last_name">Last Name:</label> <input type="text" name="ship_last_name" id="ship_last_name" value="Smith" size="" /> </li> <li> <label for="ship_state">State:</label> <select name="ship_state" id="ship_state"> <option value="RI">Rhode Island</option> <option value="VT" selected="selected">Vermont</option> <option value="CT">Connecticut</option> </select> </li> <li> <label for="ship_zip_code">Zip Code</label> <input type="text" name="ship_zip_code" id="ship_zip_code" value="05401" size="8" /> </li> <li> <input type="submit" name="" /> </li> </ul> </fieldset> </form> </div> <div> <form action="" method="get" name="billing" id="billing"> <fieldset> <legend>Billing</legend> <ul> <li> <input type="checkbox" name="copy" id="copy" /> <label for="copy">Same of my shipping</label> </li> <li> <label for="bill_first_name">First Name:</label> <input type="text" name="bill_first_name" id="bill_first_name" value="" size="" /> </li> <li> <label for="bill_last_name">Last Name:</label> <input type="text" name="bill_last_name" id="bill_last_name" value="" size="" /> </li> <li> <label for="bill_state">State:</label> <select name="bill_state" id="bill_state"> <option>-- Choose State --</option> <option value="RI">Rhode Island</option> <option value="VT">Vermont</option> <option value="CT">Connecticut</option> </select> </li> <li> <label for="bill_zip_code">Zip Code</label> <input type="text" name="bill_zip_code" id="bill_zip_code" value="" size="8" /> </li> <li> <input type="submit" name="" /> </li> </ul> </fieldset> </form> </div>

• Grails pattern to reuse template on error

  - by bsreekanth

  Hello, I have a gsp template, where the data for create view is passed through the controller. def create = { def bookInstance = new Book() bookInstance .properties = params def map = getDefaultValues() render(template: "create", model: [bookInstance : bookInstance , title: map.title, somelist: somelist ....]) the gsp template <g:select optionKey="id" from="${somelist}" name="somelist.id" value="${bookInstance ?.somelist?.id}" noSelection="['null': '']"></g:select> now, in the save method, if there is an error, it returns currently populated and validated instance (default scaffold implementation) render(template: "create", model: [bookInstance : bookInstance ]) But the fields in the gsp (error page rendered from save action) is empty. I could see the reason as it looks the value in "${somelist}" , but it is not used in save method. Do i just need to check for null in the gsp and use whichever map is available, or any better method (passing all the map in the save method is not an option) .. thanks in advance..

• How to implement SVN pre-commit hook with best performance?

  - by mliebelt

  We have the following tools in place: Subversion (Version 1.5.9) Polarion (version 3.2.2) Polarion is based on Subversion, so on every action that changes anything (which is often the case), Polarion will use a Subversion commit to change anything. All things are currently stored in one and only one repository, so every commit of every user (some 100-200 on the same repository) will trigger the pre-commit hook. So what is the best strategy to provide pre-commit hooks that will trigger only for some, but not all projects run as fast as possible, because every pre-commit hook will block all other commits. We have tried to implement pre-commit hooks with Java (using SVNKit), but this will start on every commit a Java VM. So any ideas how to implement that nicely?

• QGrid display default "loading" message when updating a table / on custom update

  - by JVXR

  I have a case where I need to update a jqgrid based on some search criteria which the user selects. I can get the data to update , but I would want the loading message to show while the new data is being fetched. Can someone please let me know how to get that working ?

• Stream a file to the HTTP response in Pylons

  - by Evgeny

  I have a Pylons controller action that needs to return a file to the client. (The file is outside the web root, so I can't just link directly to it.) The simplest way is, of course, this: with open(filepath, 'rb') as f: response.write(f.read()) That works, but it's obviously inefficient for large files. What's the best way to do this? I haven't been able to find any convenient methods in Pylons to stream the contents of the file. Do I really have to write the code to read a chunk at a time myself from scratch?

• Android application chrashes after "share" intent

  - by Johe Green

  Hi, My app offers a "share/tell-a-friend" function. When the "share" button is pressed the following method is being called to open a list of apps, which can perform the action (Eg. Gmail, Twittroid, Facebook...): public void share() { Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND); shareIntent.setType("text/plain"); shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getText(R.string.menu_share_subject)); shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, getText(R.string.menu_share_body)); startActivity(Intent.createChooser(shareIntent, getText(R.string.menu_share_intent))); } The sharing functionality works basically. But when the sharing app (Facebook, Twitter, ...) tries to return to my app, a force close is thrown. I guess that my app gets closed in the background during the sharing process... at least that is what the debugger sais... Any ideas?

• Need Help With Simple Counting Bug in iPhone SDK

  - by seanny94

  So I'm basically making an app that adds a count to a number and then displays it each time you tap the button. However, the first tap issued doesn't take any action but adds one (just as planned) on the second tap. I've searched to the ends of the earth looking for the solution with no luck, so I'll see what you guys can make of this. :) #import "MainView.h" @implementation MainView int count = 0; -(void)awakeFromNib { counter.text = @"0"; } - (IBAction)addUnit { if(count >= 999) return; NSString *numValue = [[NSString alloc] initWithFormat:@"%d", count++]; counter.text = numValue; [numValue release]; } - (IBAction)subtractUnit { if(count <= 0) return; NSString *numValue = [[NSString alloc] initWithFormat:@"%d", count--]; counter.text = numValue; [numValue release]; } @end

• Logging into table in MS SQL trigger

  - by Martin

  I am coding MS SQL 2005 trigger. I want to make some logging during trigger execution, using INSERT statement into my log table. When there occurs error during execution, I want to raise error and cancel action that cause trigger execution, but not to lose log records. What is the best way to achieve this? Now my trigger logs everything except situation when there is error - because of ROLLBACK. RAISERROR statement is needed in order to inform calling program about error. Now, my error handling code looks like: if (@err = 1) begin INSERT INTO dbo.log(date, entry) SELECT getdate(), 'ERROR: ' + out from #output RAISERROR (@msg, 16, 1) rollback transaction return end

• How do I get the name of the newest file via the Terminal?

  - by Alec

  I'm trying to create a macro for Keyboard Maestro for OS X doing the following: Get name of newest file in a directory on my disk based on date created; Paste the text "newest file: " plus the name of the newest file. One of its options is to "Execute a shell script", so I thought that would do it for 1. After Googling around a bit I came up with this: cd /path/to/directory/ ls -t | head -n1 This sorts it right, and returns the first filename. However, it also seems to includes a line break, which I do not want. As for 2: I can output the text "newest file: " with a different action in the app, and paste the filename behind that. But I'm wondering if you can't return "random text" + the outcome of the ls command. So my question is: can I do this only using the ls command? And how do I get just the name of the latest file without any linebreaks or returns?

• What code should I put on our softball Jerseys?

  - by jsmith

  I work at a small company full of software Nerds. Our wives have decided to put a Co-Ed softball team together called "The Nerds", rightfully so. One of the wives happens to be a Graphical Designer, she has come up with the brilliant idea to put Code on the Jersey (How this wasn't my idea, I have no clue). The only rule is, she wants Nerds to be a part of the code. I've been racking my brain to come up with something clever, but really haven't been able to. So I decided to open it up to my online family. Where better to ask than SO? As a simple reward to whomever gets the best answer, I planned on taking a picture of the team in their Jersey's so the winner can see their result in action.

• UISplitViewController Cannot Change the Master View Controller?

  - by Nex

  I am trying to change the master view controller (that appears in the popover in portrait, and on the left side in landscape) in a UISplitViewController. I'd like to switch between the master view controller being one of two different UIViewControllers (depending on an action taken elsewhere in my application). I am using the following: mySplitViewController.viewControllers = [NSArray arrayWithObjects:newMasterController, detailController, nil]; This correctly changes the master viewcontroller as you would expect in landscape mode. However it does not seem to change the viewcontroller used for the popover in portrait mode. I notice that the barbuttonitem to show this master view controller is just calling showMasterInPopover: on the splitviewcontroller, and so would expect it to work in portrait mode as well, but it does not. In fact, I can set the master view controller, see the new viewController correctly in landscape mode, rotate back to portrait, and the viewcontroller used in the popover is still the old one. Is this a bug?

• GetOleDbSchemaTable Foreign Keys on Sql Server 2005

  - by haxelit

  I'm trying to get the Foreign Keys for a table in my SQL Server 2005 database. I'm using the GetOleDbSchemaTable function right now: DataTable schemaTable = connection.GetOleDbSchemaTable( OleDbSchemaGuid.Foreign_Keys, new object[] { null, null, null, "TABLE" }); This pulls back the right foreign keys, the only problem is that the UpdateRule and DeleteRule are set to "No Action". If I browse to the same table in SSMS I can see that my DeleteRule is "Set NULL". Does the GetOleDbSchemaTable function not return the proper foreign key rules ? Has any one else ran into this problem ?

• NSOutlineView with Drag and Drop

  - by bob

  I read the other post here on Outlineviews and DND, but I can't get my program to work. At the bottom of this post is a link to a zip of my project. Its very basic with only an outlineview and button. I want it to receive text files being dropped on it, but something is wrong with my code or connections. I tried following Apple's example code of their NSOutline Drag and Drop, but I'm missing something. 1 difference is my program is a document based program and their example isn't. I set the File's Owner to receive delegate actions, since that's where my code to handle drag and drop is, as well as a button action. Its probably a simple mistake, so could someone please look at it and tell me what I'm doing wrong? Here is a link to the file: http://www.4shared.com/file/or1A7aHk/OutlineDragDrop.html

• Why is my asp.net mvc form POSTing instead of GETting?

  - by quakkels

  My code is straightforward enough: <% using(Html.BeginForm(FormMethod.Get)) %> <% { %> Search for in Screen Name and Email: <%: Html.TextBox("keyword", Request.QueryString["keyword"]) %> <button type=submit>Search</button> <% } %> The issue I'm running into is that when I submit this form, the values are not added to the querystring. Instead, it appears that the form is submitting by a post request. When I look at the generated HTML, I have this: <form action="/find/AdminMember/MemberList" method="post"> Search for in Screen Name and Email: <input id="keyword" name="keyword" type="text" value="" /> <button type=submit>Search</button> </form> Does anyone know why? This seems pretty simple and straighforward to me.
