309,506 | <p>I want to reveal a div with an input inside when you click a button, and set its focus.</p>
<p>If I use show(), it works, but if I use slideDown() <strong>the focus is lost after the animation completes</strong>. How can I prevent this from happening?</p>
<p>Sample code:</p>
<pre><code>$("document").ready(function(){
$("#MyButton").click(function(e){
e.preventDefault();
$(".SlidingDiv").slideDown();
$("#MyInput").focus();
});
});
<input type="button" value="Click Me" id="MyButton" />
<div class="SlidingDiv" style="display:none;"><input type="text" id="MyInput" /></div>
</code></pre>

309,522 | <p>(This is related to <a href="https://stackoverflow.com/questions/85373/floor-a-date-in-sql-server">Floor a date in SQL server</a>.)</p>
<p>Does a deterministic expression exist to floor a DATETIME? When I use this as a computed column formula:</p>
<pre><code>DATEADD(dd, DATEDIFF(dd, 0, [datetime_column]), 0)
</code></pre>
<p>the I get an error when I place an index on that column:</p>
<blockquote>
<p>Cannot create index because the key column 'EffectiveDate' is non-deterministic or imprecise.</p>
</blockquote>
<p>But both DATEDIFF and DATEADD are deterministic functions by definition. Where is the catch? Is it possible?</p>

309,539 | <p>I would like to generate a list of files within a directory. Some of the filenames contain Chinese characters.</p>
<p>eg: [试验].Test.txt</p>
<p>I am using the following code:</p>
<pre><code>require 'find'
dirs = ["TestDir"]
for dir in dirs
Find.find(dir) do |path|
if FileTest.directory?(path)
else
p path
end
end
end
</code></pre>
<p>Running the script produces a list of files but the Chinese characters are escaped (replaced with backslashes followed by numbers). Using the example filename above would produce:</p>
<p>"TestDir/[\312\324\321\351]Test.txt" instead of "TestDir/[试验].Test.txt".</p>
<p>How can the script be altered to output the Chinese characters?</p>

309,553 | <p>I commonly find myself extracting common behavior out of classes into helper/utility classes that contain nothing but a set of static methods. I've often wondered if I should be declaring these classes as abstract, since I can't really think of a valid reason to ever instantiate these? </p>
<p>What would the Pros and Cons be to declaring such a class as abstract.</p>

309,565 | <p>I'm using the StAX event based API's to modify an XML stream. The stream represents an HTML document, complete with DTD declaration. I would like to copy this DTD declaration into the output document (written using an <code>XMLEventWriter</code>). When I ask the factory to disregard DTD's it will not download the DTD, but remove the whole statement and only leave a "<code><!DOCUMENTTYPE</code>" string. When not disregarding, the whole DTD gets downloaded, and included when verbatim outputting the DTD event. I don't want to use the time to download this DTD, but include the complete DTD specification (resolving entities is already disabled and I don't need that). Does anyone know how to disable the fetching of external DTD's.</p>

309,615 | <p>I'd like to establish an ssh tunnel over ssh to my mysql server.</p>
<p>Ideally I'd return a mysqli db pointer just like I was connecting directly.</p>
<p>I'm on a shared host that doesn't have the <a href="http://ca.php.net/ssh2" rel="noreferrer">SSH2</a> libraries but I might be able to get them installed locally using PECL.</p>
<p>If there's a way that uses native commands that would be great.</p>
<p>I was thinking something like this, but without those libraries it won't work.</p>
<pre><code>$connection = ssh2_connect('SERVER IP', 22);
ssh2_auth_password($connection, 'username', 'password');
$tunnel = ssh2_tunnel($connection, 'DESTINATION IP', 3307);
$db = new mysqli_connect('127.0.0.1', 'DB_USERNAME', 'DB_PASSWORD',
'dbname', 3307, $tunnel)
or die ('Fail: ' . mysql_error());
</code></pre>
<p>Anyone have any ideas? I'm running a shared CentOS linux host at liquidweb.</p>
<p>Any thoughts on making the tunnel persistent? Is it possible to establish it with another script and just take advantage of it in <code>PHP</code>?</p>
<p>Thanks.</p>

309,631 | <p>In what cases is it necessary to synchronize access to instance members?
I understand that access to static members of a class always needs to be synchronized- because they are shared across all object instances of the class.</p>
<p>My question is when would I be incorrect if I do not synchronize instance members? </p>
<p>for example if my class is</p>
<pre><code>public class MyClass {
private int instanceVar = 0;
public setInstanceVar()
{
instanceVar++;
}
public getInstanceVar()
{
return instanceVar;
}
}
</code></pre>
<p>in what cases (of usage of the class <code>MyClass</code>) would I <em>need</em> to have methods:
<code>public synchronized setInstanceVar()</code> and
<code>public synchronized getInstanceVar()</code> ?</p>
<p>Thanks in advance for your answers.</p>

309,639 | <p>The following questions are about XML serialization/deserialization and schema validation for a .net library of types which are to be used for data exchange.</p>
<hr>
<p>First question, if I have a custom xml namespace say "<a href="http://mydomain/mynamespace" rel="nofollow noreferrer">http://mydomain/mynamespace</a>" do I have to add a</p>
<pre><code>[XmlRoot(Namespace = "http://mydomain/mynamespace")]
</code></pre>
<p>to every class in my library. Or is there a way to define this namespace as default for the whole assembly?</p>
<hr>
<p>Second question, is there a reason behind the always added namespaces</p>
<pre><code>xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
</code></pre>
<p>even if there is no actual reference to any of the namespaces? I just feel they add noise to the resulting xml. Is there a way to remove them an only have the custom namespace in the resulting xml?</p>
<hr>
<p>Third question, are there tools to support the generation of schema definitions (e.g. for all public [Serializable] classes of an assembly) and the validation of xml against specific schemas available?</p>
<p>If there are, would you recommend XML Schema from W3C or RELAX NG?</p>

309,675 | <p>I am creating an touch screen application using Swing and have a request to change one of buttons so that it will behave like a keyboard when the button is held down.<br>
(First of all, I am not sure that the touch screen will allow the user to "hold down" the button, but pretend that they can for now)</p>
<p>I was going to go down the path of starting a loop when <code>mousePressed</code> was called and then ending the loop when <code>mouseReleased</code> was called. This will involve starting a thread and having to deal with synchronization as well as <code>invokeLater()</code> to get events back on the <code>EventQueue</code>.</p>

309,682 | <p>I'm writing a HTML form that's divided in fieldsets, and I need to get the form fields from a specific fiedset in a function.<br>
Currently it's like this: </p>

var Selects = Fieldset.getElementsByTagName("select");
/* Doing the stuff I need to do in two iterations, one for each field type */
}

<p>But who knows what the future may hold, and if the form gets some new field types (radios, checkboxes) this could become awful to mantain.<br>
I know that <code>form</code> elements have the <code>elements</code> attribute that returns all the form fields and I was hoping I could use something like that.<br>
(I know I still gotta discriminate the field type in a bunch of conditionals inside the iteration, but I think it would be faster and easier to keep. Unless it isn't and I should not be doing it)</p>

309,683 | <p>I have a page with a few fields and a runtime-generated image on it. The contents of this page are inside an UpdatePanel. There is a button to take the user to a secondary page, which has a button that calls javascript:history.go(-1) when clicked.</p>
<p>The problem is, the first page does a full request instead of a postback or just using the state it was in before navigating away from it. That is, the fields are all reset to their default values, thereby confusing the user. I'd like their values to be retained regardless of navigation. I do not want to create a new history state for every field change.</p>

309,706 | <p>So i'm not really sure why this is happening but I'm running through some DataRows where I have the control name, property, and value that I want to set. Everything works fine except when I set the TEXT property of a button. For some reason, the click event is called...</p>
<p>Here's some of the code I've got:</p>
<pre><code>string controlName, value, property;
Control currentControl = null;
System.Reflection.PropertyInfo propertyInfo = null;
// run through all rows in the table and set the property
foreach (DataRow r in languageDataset.Tables[_parentForm.Name].Rows)
{
controlName = r["ControlName"].ToString().ToUpper();
value = r["Value"].ToString();
property = r["Property"].ToString();
// check all controls on the form
foreach (Control c in formControls)
{
// only change it if its the right control
if (c.Name.ToUpper() == controlName)
{
propertyInfo = c.GetType().GetProperty(property);
if (propertyInfo != null)
propertyInfo.SetValue(c, value, null); ******Calls Event Handler?!?!******
//
currentControl = c;
break;
}
}
}
</code></pre>
<p>So why in the world would it call the event handler when setting the value? Here's what I'm setting it with that's causing this:</p>
<pre><code><SnappletChangePassword>
<ControlName>buttonAcceptPassword</ControlName>

309,713 | <p>I'm using a Flash TextField control to display some HTML content inside a Flash presentation to be shown on a large touch-screen kiosk. Unfortunately, if any image tag in the displayed HTML content points to a non-existent image, a dialogue is shown with the error message </p>
<pre><code>Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
</code></pre>
<p>I am trying to avoid having that dialogue pop up. The <a href="http://www.kirupa.com/forum/showthread.php?t=287501" rel="nofollow noreferrer">solution</a> for loading content through a loader class is to catch <code>IOErrorEvent.IO_ERROR</code>, but I've tried listening for that on the TextField, on stage, Main and loaderInfo to no avail. I've tried wrapping the whole thing in a try-catch, and that also doesn't work.</p>
<p>Here's the simplified code I'm using to find solutions:</p>
<pre><code>package {
import flash.display.Sprite;
import flash.errors.IOError;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.text.TextField;
import flash.text.TextFieldType;
public class Main extends Sprite {
public function Main():void {
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, init);
var html:TextField = new TextField();
html.type = TextFieldType.DYNAMIC;
html.multiline = true;
html.htmlText = "Bogus image: <img src=\"foo.jpg\" />";
addChild(html);
}
}
}
</code></pre>
<p><strong>Edit: And here's the entire working code.</strong></p>
<p>For dynamic content and so forth, of course, you would need a list of images and a function to generate handlers, etc.</p>
<pre><code>package {
import flash.display.Loader;
import flash.display.Sprite;
import flash.errors.IOError;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.text.TextField;
import flash.text.TextFieldType;
public class Main extends Sprite {
public function Main():void {
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, init);
var html:TextField = new TextField();
html.type = TextFieldType.DYNAMIC;
html.multiline = true;
html.htmlText = "Bogus image: <img id=\"image\" src=\"foo.jpg\" />";
var loader:Loader = html.getImageReference("image") as Loader;
if(loader){
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, function(e:Event):void {
trace("Error loading foo.jpg!");
});
}
addChild(html);
}
}
}
</code></pre>

309,723 | <p>Is there a way to view the list of <em>recent documents</em> you've opened in Vim?</p>
<p>I realize I could view the cursor <em>jump list</em>, <code>:ju</code>, and then go to a cursor position in the list but this is not ideal because there will be multiple listings of the same document in the list.</p>
<p>Is there another command which would do what I'm looking for?</p>

309,734 | <p>I need to be able to take an arbitrary text input that may have a byte order marker (BOM) on it to mark its encoding, and output it as ASCII. We have some old tools that don't understand BOM's and I need to send them ASCII-only data.</p>
<p>Now, I just got done writing this code and I just can't quite believe the inefficiency here. Four copies of the data, not to mention any intermediate buffers internally in StreamReader. Is there a better way to do this?</p>
<pre><code>// i_fileBytes is an incoming byte[]
string unicodeString = new StreamReader(new MemoryStream(i_fileBytes)).ReadToEnd();
byte[] unicodeBytes = Encoding.Unicode.GetBytes(unicodeString.ToCharArray());
byte[] ansiBytes = Encoding.Convert(Encoding.Unicode, Encoding.ASCII, unicodeBytes);
string ansiString = Encoding.ASCII.GetString(ansiBytes);
</code></pre>
<p>I need the StreamReader() because it has an internal BOM detector to choose the encoding to read the rest of the file. Then the rest is just to make it convert into the final ASCII string.</p>
<p>Is there a better way to do this?</p>

309,737 | <p>I'm using the Apache Commons EqualsBuilder to build the equals method for a non-static Java inner class. For example:</p>
<pre><code>import org.apache.commons.lang.builder.EqualsBuilder;
public class Foo {
public class Bar {
private Bar() {}
public Foo getMyFoo() {
return Foo.this
}
private int myInt = 0;
public boolean equals(Object o) {
if (o == null || o.getClass() != getClass) return false;
Bar other = (Bar) o;
return new EqualsBuilder()
.append(getMyFoo(), other.getMyFoo())
.append(myInt, other.myInt)
.isEquals();
}
}
public Bar createBar(...) {
//sensible implementation
}
public Bar createOtherBar(...) {
//another implementation
}
public boolean equals(Object o) {
//sensible equals implementation
}
}
</code></pre>
<p>Is there syntax by which I can refer to <code>other</code>'s <code>Foo</code> reference apart from declaring the <code>getMyFoo()</code> method? Something like <code>other.Foo.this</code> (which doesn't work)?</p>

<p>class_d extends class_c and class_b</p>
<p>moreover can you do this if class_c and class_b are themselves extended from class_a ... so you get something like this</p>

309,775 | <p>I want to design a class that will parse a string into tokens that are meaningful to my application.</p>
<p>How do I design it?</p>
<ol>
<li>Provide a ctor that accepts a string, provide a Parse method and provide methods (let's call them "minor") that return individual tokens, count of tokens etc. OR</li>
<li>Provide a ctor that accepts nothing, provide a Parse method that accepts a string and minor methods as above. OR</li>
<li>Provide a ctor that accepts a string and provide only minor methods but no parse method. The parsing is done by the ctor.</li>
</ol>
<p>1 and 2 have the disadvantage that the user may call minor methods without calling the Parse method. I'll have to check in every minor method that the Parse method was called.</p>
<p>The problem I see in 3 is that the parse method may potentially do a lot of things. It just doesn't seem right to put it in the ctor.</p>
<p>2 is convenient in that the user may parse any number of strings without instantiating the class again and again.</p>
<p>What's a good approach? What are some of the considerations?</p>
<p>(the language is c#, if someone cares).</p>
<p>Thanks</p>

309,790 | <p>In Java, what is the difference between the twin methods?</p>
<pre><code>public void methodA() throws AnException {
//do something
throw new AnException();
}
public void methodA() {
//do the same thing
throw new AnException();
}
</code></pre>
<p>I have a intuition that it has something to do with being a well-designed method (because I put methodA in an interface, declared it the way methodA* does in its implementation and received a warning from Java that "A* cannot override A because A* doesn't throw AnException"). </p>
<p>Is this speculation correct? </p>
<p>Is there any other subtle connotations in the two ways of doing things?</p>

309,834 | <p>I have a read query that I execute within a transaction so that I can specify the isolation level. Once the query is complete, what should I do?</p>
<ul>
<li>Commit the transaction </li>
<li>Rollback the transaction</li>
<li>Do nothing (which will cause the transaction to be rolled back at the end of the using block)</li>
</ul>
<p>What are the implications of doing each?</p>
<pre><code>using (IDbConnection connection = ConnectionFactory.CreateConnection())
{
using (IDbTransaction transaction = connection.BeginTransaction(IsolationLevel.ReadUncommitted))
{
using (IDbCommand command = connection.CreateCommand())
{
command.Transaction = transaction;
command.CommandText = "SELECT * FROM SomeTable";
using (IDataReader reader = command.ExecuteReader())
{
// Read the results
}
}
// To commit, or not to commit?
}
}
</code></pre>
<p>EDIT: The question is not if a transaction should be used or if there are other ways to set the transaction level. The question is if it makes any difference that a transaction that does not modify anything is committed or rolled back. Is there a performance difference? Does it affect other connections? Any other differences?</p>

309,880 | <p>I'm trying to create a custom transition, to serve as a replacement for a default transition you would get here, for example:</p>
<pre><code>[self.navigationController pushViewController:someController animated:YES];
</code></pre>
<p>I have prepared an OpenGL-based view that performs an effect on some static texture mapped to a plane (let's say it's a copy of the flip effect in Core Animation). What I don't know how to do is:</p>
<ul>
<li>grab current view content and make a texture out of it (I remember seeing a function that does just that, but can't find it)</li>
<li>how to do the same for the view that is currently offscreen and is going to replace current view </li>
<li>are there some APIs I can hook to in order to make my transition class as native as possible (make it a kind of Core Animation effect)?</li>
</ul>
<p>Any thoughts or links are greatly appreciated!</p>
<p><strong>UPDATE</strong></p>
<p>Jeffrey Forbes's answer works great as a solution to capture the content of a view. </p>
<p>What I haven't figured out yet is how to capture the content of the view I want to transition to, which should be invisible until the transition is done.</p>
<p>Also, which method should I use to present the OpenGL view?
For demonstration purposes I used pushViewController. That affects the navbar, though, which I actually want to go one item back, with animation, check this vid for explanation:</p>
<p><a href="http://vimeo.com/4649397" rel="noreferrer">http://vimeo.com/4649397</a>.</p>
<p>Another option would be to go with presentViewController, but that shows fullscreen.
Do you think maybe creating another window (or view?) could be useful?</p>

309,884 | <p>The code golf series seem to be fairly popular. I ran across some code that converts a number to its word representation. Some examples would be (powers of 2 for programming fun):</p>
<ul>
<li>2 -> Two</li>
<li>1024 -> One Thousand Twenty Four</li>
<li>1048576 -> One Million Forty Eight Thousand Five Hundred Seventy Six</li>
</ul>
<p>The algorithm my co-worker came up was almost two hundred lines long. Seems like there would be a more concise way to do it.</p>
<p>Current guidelines:</p>
<ul>
<li>Submissions in any <strong>programming</strong> language welcome (I apologize to
PhiLho for the initial lack of clarity on this one)</li>
<li>Max input of 2^64 (see following link for words, thanks mmeyers)</li>
<li><a href="http://en.wikipedia.org/wiki/Long_and_short_scales" rel="nofollow noreferrer">Short scale</a> with English output preferred, but any algorithm is welcome. Just comment along with the programming language as to the method used.</li>

309,892 | <p>I ran into an interesting behavior recently. It seems that if I override .equals() to take a parameter other than Object, it doesn't get called. Can anyone explain to me why this is happening? It seems to violate my understanding of polymorphism in OOP, but maybe I'm missing something.</p>
<p>Here's much simpler code that shows what I'm seeing:</p>
<pre><code>public class MyClass {
private int x;
public MyClass(int n) { x = n; }
public boolean equals(Object o) { return false; }
public boolean equals(MyClass mc) { return x == mc.x; }
public static void main(String[] args) {
List<MyClass> list = new ArrayList<MyClass>();
list.add(new MyClass(3));
System.out.println("Contains 3? " + list.contains(new MyClass(3)));
}
}
</code></pre>
<p>When this is run, it prints "<code>Contains 3? false</code>". It looks like the equals(Object) function is called, even though there is another that would work. By contrast, if I write equals like this the code works as expected:</p>
<pre><code>public boolean equals(Object o) {
if(!(o instanceof MyClass))
return false;
MyClass mc = (MyClass)o;
return x == mc.x;
}
</code></pre>
<p>Why isn't it figuring out which version of the function to call based on the type of the parameter?</p>

309,921 | <p>Wondering how to open many new windows with Javascript. I have found plenty of places on the internet that show you how to open a new browser window with Javascript, but I want to open a new UNIQUE window. For Example.</p>
<p>I have two links on a page. the user clicks on both links and they are both opened in the same window. I want each link to open a new window WITH JAVASCRIPT.</p>
<p>Another Example.
<strong>I just opened a window with javascript and I have a link inside my newly opened window. I click on the link and it opens in the same window. I want to pop it out of that window WITH JAVASCRIPT, NOT use the same window.</strong></p>
<p>Help?</p>

309,930 | <p>I've got a database with three tables: Books (with book details, PK is CopyID), Keywords (list of keywords, PK is ID) and KeywordsLink which is the many-many link table between Books and Keywords with the fields ID, BookID and KeywordID.</p>
<p>I'm trying to make an advanced search form in my app where you can search on various criteria. At the moment I have it working with Title, Author and Publisher (all from the Book table). It produces SQL like:</p>
<pre><code>SELECT * FROM Books WHERE Title Like '%Software%' OR Author LIKE '%Spolsky%';
</code></pre>
<p>I want to extend this search to also search using tags - basically to add another OR clause to search the tags. I've tried to do this by doing the following</p>
<pre><code>SELECT *
FROM Books, Keywords, Keywordslink
WHERE Title LIKE '%Joel%'
OR (Name LIKE '%good%' AND BookID=Books.CopyID AND KeywordID=Keywords.ID)
</code></pre>
<p>I thought using the brackets might separate the 2nd part into its own kinda clause, so the join was only evaluated in that part - but it doesn't seem to be so. All it gives me is a long list of multiple copies of the one book that satisfies the <code>Title LIKE '%Joel%'</code> bit.</p>
<p>Is there a way of doing this using pure SQL, or would I have to use two SQL statements and combine them in my app (removing duplicates in the process).</p>
<p>I'm using MySQL at the moment if that matters, but the app uses ODBC and I'm hoping to make it DB agnostic (might even use SQLite eventually or have it so the user can choose what DB to use).</p>

309,939 | <p>I have a class library with all my database logic. My DAL/BLL. </p>
<p>I have a few web projects which will use the same database and classes, so I thought it was a good idea to abstract the data layer into its own project.</p>
<p>However, when it comes to adding functionality to classes for certain projects I want to add methods to certain classes.</p>
<p>For example, my data layer has Product and SomeItem objects:</p>
<pre><code>// Data Access Layer project
namespace DAL {
public class Product {
//implementation here
}
public class SomeItem {
//implementation here
}
}
</code></pre>
<p>In one project I want to add an interface that is used by different content items, so I have a class called:</p>
<pre><code>// This is in Web Project
namespace DAL {
public partial class Product : ICustomBehaviour {
#region ICustomBehaviour Implementation
TheSharedMethod();
#endregion
}
}
</code></pre>
<p><strong>Is it a good idea to write a partial class in a separate project (creating a dependency) using the <em>same</em> namespace? If it's a bad idea, how can I get this type of functionality to work?</strong></p>
<p>It doesn't seem to want to merge them at compile time, so I'm not sure what I'm doing wrong.</p>

309,945 | <p>For some reasons, I would like to do an explicit quoting of a string value (becoming a part of constructed SQL query) instead of waiting for implicit quotation performed by <code>cursor.execute</code> method on contents of its second parameter.</p>
<p>By "implicit quotation" I mean:</p>
<pre><code>value = "Unsafe string"
query = "SELECT * FROM some_table WHERE some_char_field = %s;"
cursor.execute( query, (value,) ) # value will be correctly quoted
</code></pre>
<p>I would prefer something like that:</p>
<pre><code>value = "Unsafe string"
query = "SELECT * FROM some_table WHERE some_char_field = %s;" % \
READY_TO_USE_QUOTING_FUNCTION(value)
cursor.execute( query ) # value will be correctly quoted, too
</code></pre>
<p>Is such low level <code>READY_TO_USE_QUOTING_FUNCTION</code> expected by Python DB API specification (I couldn't find such functionality in <a href="http://www.python.org/dev/peps/pep-0249/" rel="noreferrer">PEP 249</a> document). If not, maybe Psycopg2 provides such function? If not, maybe Django provides such function? I would prefer not to write such function myself...</p>

309,953 | <p>Is it possible to catch an error when using JSONP with jQuery? I've tried both the $.getJSON and $.ajax methods but neither will catch the 404 error I'm testing. Here is what I've tried (keep in mind that these all work successfully, but I want to handle the case when it fails):</p>
<pre><code>jQuery.ajax({
type: "GET",
url: handlerURL,
dataType: "jsonp",
success: function(results){
alert("Success!");
},
error: function(XMLHttpRequest, textStatus, errorThrown){
alert("Error");
}
});
</code></pre>
<p>And also:</p>
<pre><code>jQuery.getJSON(handlerURL + "&callback=?",
function(jsonResult){
alert("Success!");
});
</code></pre>
<p>I've also tried adding the $.ajaxError but that didn't work either:</p>
<pre><code>jQuery(document).ajaxError(function(event, request, settings){
alert("Error");
});
</code></pre>
<p>Thanks in advance for any replies!</p>

309,979 | <p>I have a LinkButton that has to postback to perform some logic.</p>
<p>Once it is finished, instead of loading the page back up in the browser, I want to leave it alone and pop open a new window.</p>
<p>So far, the best idea I've had is to put the LinkButton in an UpdatePanel, and have it render some JavaScript out when it reloads, yet I think that is totally hacky. Also, if I recall right, JavaScript within a update panel won't run anyways.</p>
<p>Any other ideas?</p>

309,991 | <p>I have a just one table mapped in a datacontext. Here's the property and attribute on the column of interest:</p>
<pre><code>[Column(Storage="_CustomerNumber", DbType="VarChar(25)")]
public string CustomerNumber
{
</code></pre>
<p>This column is, in fact, a varchar(25) and has an index.</p>
<p>I've got some simple code:</p>
<pre><code>DataClasses1DataContext myDC = new DataClasses1DataContext();
myDC.Log = Console.Out;
List<string> myList = new List<string>() { "111", "222", "333" };
myDC.Customers
.Where(c => myList.Contains(c.CustomerNumber))
.ToList();
</code></pre>
<p>Which generates this SQL text:</p>
<pre><code>SELECT [t0].[CustomerNumber], [t0].[CustomerName]
FROM [dbo].[Customers] AS [t0]
WHERE [t0].[CustomerNumber] IN (@p0, @p1, @p2)
-- @p0: Input NVarChar (Size = 3; Prec = 0; Scale = 0) [111]
-- @p1: Input NVarChar (Size = 3; Prec = 0; Scale = 0) [222]
-- @p2: Input NVarChar (Size = 3; Prec = 0; Scale = 0) [333]
-- Context: SqlProvider(Sql2005) Model: AttributedMetaModel Build: 3.5.21022.8
</code></pre>
<p>Notice that the paramaters are nvarchar!</p>
<p>When this query hits the database, it generates a horrible plan which involves <strong>converting the multi-million row index on CustomerNumber to nvarchar</strong> before seeking within it.</p>
<p>I'm not allowed to change the table, but I can change the query and the dbml. What can I do to get the data out without getting this index conversion?</p>

310,010 | <p>There are (at least) two ways that technical debts make their way into projects. The first is by conscious decision. Some problems just are not worth tackling up front, so they are consciously allowed to accumulate as technical debt. The second is by ignorance. The people working on the project don't know or don't realize that they are incurring a technical debt. This question deals with the second. Are there technical debts that you let into your project that would have been trivial to keep out ("If I had only known...") but once they were embedded in the project, they became dramatically more costly? </p>

310,017 | <p>I see two types of examples in various places. One uses form fields like</p>
<blockquote>
<p>curl -X PUT -d "phone=123.456.7890" "<a href="http://127.0.0.1/services/rest/user/123" rel="nofollow noreferrer">http://127.0.0.1/services/rest/user/123</a>"</p>
</blockquote>
<p>and the other uses an XML content like (some variation of) this</p>
<blockquote>
<p>echo "<user><id>123</id><phone>123.456.7890</phone></user>" | curl -X PUT -d @- "<a href="http://127.0.0.1/services/rest/user/" rel="nofollow noreferrer">http://127.0.0.1/services/rest/user/</a>"</p>
</blockquote>
<p>It seems like using the form fields has the advantage of brevity and clearly identifying the client's intent by targeting just the modified fields, but makes it awkward to address "deeper" metadata.</p>
<p>Using the XML content has an advantage of being more complete, but the disadvantage of the overhead of figuring out which field the client is actually modifying (assuming that they send back the entire resource with small modifications).</p>
<p>Is there a best practice, or even a more-common practice?</p>

310,058 | <p><strong>Problem Statement:</strong>
I would like to create an offline database to lookup prices/info on the n most useful books to sell in the United States (where n is probably 3 million or so). </p>
<p><strong>Question:</strong>
So, my question is (and I am open to other approaches here as well), I am trying to figure out how to use Amazon AWS to download a list of the n higest salesrank books being sold as well as some information about the book (i.e. title, prices, etc...).</p>
<p><strong>What I have done so far:</strong>
First, something like this exists already (asellertool.com), however, I thought this would be an interesting project to work on and quite frankly, we aren't serious enough to need to pay the $30/month subscription.</p>
<p>Now, AWS is great (and easy) if you have a few items you want to look up, but I can't seem to figure out how enumerate on sales rank.
Originally, I was hoping to enumerate all of the book items Amazon had by ISBN. But that wasn't available either. Then I thought I could find a list of all ISBN numbers out there, but that was a dead end too. Finally I thought I could create my own list of ISBN numbers, but as I did some back of the envelope calculations, I thought better of it as my solutions would take roughly a year to go through a third of the 10 digit space at 100/second (and it was overkill anyway).</p>
<p>So, I am back on Sales Ranking, which is currently seems like a dead end as well. So, if you have any thoughts, I would appreciate it.</p>

<p><code>show_info_for_all_items.html</code> shows a list of items along with each item's info.</p>
<p><code>show_info_for_single_item.html</code> shows a single item with the item's info.</p>
<p><code>show_info_for_all_items.html</code> and <code>show_info_for_single_item.html</code> share same code for showing item info, so I moved it to <code>item_base.html</code> into <code>block item_info</code></p>
<p>but the <code>{{ block.super }}</code> in <code>show_info_for_all_items.html</code> and <code>show_info_for_single_item.html</code> does not work. <code>{{ block.super }}</code> resolves as blank.</p>
<p>If I move the code back from <code>block item_info</code> in <code>item_base.html</code> into <code>show_info_for_all_items.html</code> and <code>show_info_for_single_item.html</code> it works but then I have to duplicate same <code>block item_info</code> code in 2 files.</p>
<p>If the block.super issue can not be solved, does Django offer something like INCLUDE => <code>{% INCLUDE "item_base.html" %}</code> so blocks from a template file can be included ( instead of <code>extends</code> )</p>
<p>How do I avoid duplicating <code>block item_info</code> in both html files?</p>

310,105 | <p>I've been discussing a code style issue with a friend. We have a series of packages that implement an interface by returning a specific type of value via a named subroutine. For example:</p>
<pre><code>package Foo::Type::Bar;
sub generate_foo {
# about 5-100 lines of code
return stuff here;
}
</code></pre>
<p>So you can go:</p>
<pre><code>my $bar_foo = Foo::Type::Bar->generate_foo;
my $baz_foo = Foo::Type::Baz->generate_foo;
</code></pre>
<p>We have many of these, all under the same <code>Foo::Type::*</code> hierarchy.</p>
<p>I think the packages should clearly indicate that they implement the <code>foo_generate</code> interface, e.g.:</p>
<pre><code>package Foo::Type::Bar;
use base 'Foo::Type';
sub generate_foo {
...
return stuff here;
}
</code></pre>
<p>I think this is good code style, much more clear and clean for other coders exploring the code. It also lets you check <code>Foo::Type::Bar->isa('Foo::Type')</code> to see if it implements the interface (other parts of the subsystem are entirely OO).</p>
<p>My friend disagrees. Some arguments he makes are:</p>
<ul>
<li><code>Foo::Type::*</code> packages are clearly named, and used only in an internal project, and therefore there's no question of wondering whether or not a given package implements an interface</li>
<li>the packages are often small and part of a standalone subsystem, and they feel to him like batch files or conf files, not heavy Perl OO code</li>
<li>Perl expresses implementation via inheritance, which may be complex or problematic, particularly when one gets to multiple inheritance</li>
<li>adding a <code>Foo::Type</code> superclass doesn't add any value, as it would literally be an empty package, used only to enable <code>->isa</code> lookups</li>
<li>programmatically indicating interface implementation is a matter of personal code style</li>
</ul>
<p>Is one or the other of us "right"? What would you do?</p>
<p><em>Edit: in examples, renamed Foo::Generator to Foo::Type</em></p>

310,108 | <p>Following is some obviously-defective code for which I think the compiler should emit a diagnostic. But neither <code>gcc</code> nor <code>g++</code> does, even with all the warnings options I could think of: <code>-pedantic -Wall -Wextra</code></p>
<pre><code>#include <stdio.h>
short f(short x)
{
return x;
}
int main()
{
long x = 0x10000007; /* bigger than short */
printf("%d\n", f(x)); /* hoping for a warning here */
return 0;
}
</code></pre>
<p>Is there a way to make <code>gcc</code> and <code>g++</code> warn about this? On a side note, do you have another compiler which warns about this by default or in a fairly common extra-warnings configuration?</p>
<p>Note: I'm using GCC (both C and C++ compilers) version 4.2.4.</p>
<p>Edit: I just found that <code>gcc -Wconversion</code> does the trick, but the same option to <code>g++</code> doesn't, and I'm really using C++ here, so I need a solution for <code>g++</code> (and am now wondering why <code>-Wconversion</code> doesn't seem to be it).</p>
<p>Edit: <a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34389" rel="noreferrer">http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34389</a> suggests that this may be fixed in <code>g++ 4.4</code>...maybe? It's not clear to me yet if it's the same issue and/or if the fix is really coming in that version. Maybe someone with 4.3 or 4.4 can try my test case.</p>

310,115 | <p>I am writing a script which is likely to be modified by users. Currently I am storing the configuration settings inside the script. It exists in the form of a hash-of-hashes.</p>
<p>I would like to guard against people accidentally using lowercase characters in the hash keys, because that will break my script.</p>
<p>It would be simple to inspect the hash keys and merely issue warnings for any keys with lowercase characters, but I would rather fix the case sensitivity automatically.</p>
<p>In other words, I want to convert all the hash keys in the top-level hash to uppercase.</p>

310,160 | <p>I'm experimenting with WCF Services, and have come across a problem with passing Interfaces.</p>
<p>This works:</p>
<pre><code>[ServiceContract]
public interface IHomeService
{
[OperationContract]
string GetString();
}
</code></pre>
<p>but this doesn't:</p>
<pre><code>[ServiceContract]
public interface IHomeService
{
[OperationContract]
IDevice GetInterface();
}
</code></pre>
<p>When I try to compile the client it fails on the GetInterface method. I get an Exception saying that it can't convert Object to IDevice.</p>
<p>On the clientside the IHomeService class correctly implements GetString with a string as it's returntype, but the GetInterface has a returntype of object. Why isn't it IDevice?</p>

310,164 | <p>I'm trying to work my way through Ron Jeffries's Extreme Programming Adventures in C#. I am stuck, however, in Chapter 3 because the code does not, and <b>cannot</b>, do what the author says it does. </p>
<p>Basically, the text says that I should be able to write some text in a word-wrap enabled text box. If I then move the cursor to an intermediate line and hit enter, the code should re-display the lines before the cursor, add a couple of lines and a set of HTML paragraph tags, then append the rest of the lines. The code doesn't match the text because it uses the textbox.lines property. Well, no matter how many word-wrapped lines there are in a text box, there's only ONE line in the Lines property until you hit a carriage return. So, the statement that the code should, "Copy the rest of the lines into the buffer" appears wrong to me. </p>
<p>I'd appreciate anybody having experience with the book telling me what I'm reading, or doing, wrong!</p>
<p>Thanks.</p>

<GetListResult>

310,245 | <p>I'm trying to get a stored procedure to work for a co-worker who is out sick (and thus can't be asked for guidance).</p>
<p>I have a SQL Server 2005 database that has this exact procedure, and I'm trying to make the scripts to convert a test database to match this dev database. My script has several lines like:</p>
<pre><code>CAST(RELATIVE_ERROR_RATIO AS FLOAT),
CAST(REPORTING_LIMIT AS FLOAT),
</code></pre>
<p>The procedure is essentially doing an "insert into table (all the fields) from another table where field = @input"</p>
<p>When I run the script, I get the error:</p>
<pre><code>CAST or CONVERT: invalid attributes specified for type 'float'
</code></pre>
<p>and the procedure is not created. But, I've compared the source tables in both the dev and test environments, and they match exactly. And the procedure exists exactly as scripted in the dev environment. </p>
<p>I can't ask my co-worker if he had to do any special acrobatics to create this script, so I'm asking you. I've done some searching, and see that perhaps float should be of the form FLOAT(6,1) (or some such), but that's NOT what he has, and I'm not comfortable changing the test environment so that it won't really match dev.</p>
<p><strong>Added</strong></p>
<p>The commenter is correct. I've been told that the error is with the following cast: </p>
<pre><code>CAST(TRACER_YIELD AS FLOAT(10,3)),
</code></pre>
<p>I could post the entire query, but it's a long one! So, instead, I'll just include the casted fields, and the first and last field. I'd like to ask my co-worker if that one field was a mistake, and it just needed a straight cast. He'll be back next monday, so it may need to wait that long.</p>

310,247 | <p>Whenever I create a method signature in VS 2008 (C#), I type the two braces:</p>
<p>public void Something() {}</p>
<p>This leaves the cursor to the right of the closing brace. Then I have to use the arrow keys to reposition the cursor in between the braces. Is there a better way to do this without using the arrow keys?</p>
<p>I'd expect it to place the cursor in between the braces when I type the closing one so I can start typing code.</p>

310,271 | <p>I'm an end-user of one of my company's products. It is not very suitable for integration into Spring, however I am able to get a handle on the context and retrieve the required bean by name. However, I would still like to know if it was possible to inject a bean into this class, even though the class is not managed by Spring itself.</p>
<p>Clarification: The same application which is managing the lifecycle of some class MyClass, is also managing the lifecycle of the Spring context. Spring does not have any knowledge of the instance of MyClass, and I would like to some how provide the instance to the context, but cannot create the instance in the context itself.</p>

310,282 | <p>Recently, I found myself having to write up some concerns I have about race conditions in an application that is in development (not by me). This will likely be brought to the attention of stakeholders who are non-technical and with whom I do not have a direct line of communication, so my explanation needs to be in written form.</p>
<p>I have already made an attempt at this write-up. I gloss over the technical specifics as best I can, give an example of how a race condition would occur in the application, and describe its impact. I feel I did pretty well, but it's far from perfect.</p>
<p>The problem is, as much as I try to shield the reader from computer science, I have still found it difficult to eliminate phrases like "threads of execution" and "mutual exclusion" without losing correctness and substance. The risk is that, with too much hand-waving, these concerns could be dismissed as a made-up boogeyman.</p>
<p>Anyway, my question to you is this: <strong>How would <em>you</em> explain race conditions to a non-technical audience?</strong> Would you dare to explain CPU scheduling? Would you invoke the <a href="http://en.wikipedia.org/wiki/Dining_philosophers_problem" rel="noreferrer">dining philosophers</a>?</p>
<p><em>You don't have to work within the constraints of my situation (but it would be awesomely helpful if you did).</em></p>

310,286 | <p>The default behavior of NHibernate is the write all changes to objects to the database when Session.Flush() is called. It does this whether you want it to or not.</p>
<p>How do we prevent writing bad data to the database when we need to do things like validate business rules or input?</p>
<p>For instance .. </p>
<ul>
<li>Customer Name is not null. </li>
<li>User opens a web browser (without javascript) and deletes the customer name. </li>
<li>Hits update. </li>
<li><code>Customer.Name</code> property is updated and .. </li>
<li><code>Customer.IsValid()</code> is called. </li>
<li>Even if <code>IsValid()</code> is false and we show error messages NHibernate still updates the database.</li>
</ul>

310,294 | <p>I'm using a regex that <a href="http://regexlib.com/REDetails.aspx?regexp_id=646" rel="nofollow noreferrer">strips the href tags out of an html doc</a> saved to a string. The following code is how I'm using it in my C# console app.</p>
<pre><code>Match m = Regex.Match(htmlSourceString, "href=[\\\"\\\'](http:\\/\\/|\\.\\/|\\/)?\\w+(\\.\\w+)*(\\/\\w+(\\.\\w+)?)*(\\/|\\?\\w*=\\w*(&\\w*=\\w*)*)?[\\\"\\\']");
if (m.Success)
{
Console.WriteLine("values = " + m);
}
</code></pre>
<p>However, it only returns one result, instead of a list of all the href tags on the html page. I know it works, because when I trying <code>RegexOptions.RightToLeft</code>, it returns the last href tag in the string. </p>
<p>Is there something with my if statement that doesn't allow me to return all the results?</p>

310,307 | <p>Earlier I asked this question <a href="https://stackoverflow.com/questions/309708/how-to-correctly-unit-test-my-dal">How to correctly unit test my DAL?</a>, one thing left unanswered for me is if to really test my DAL is to have a Test DB, then what is the role of mocking vs. a testing DB?</p>
<p>To add on this, another person suggested to "use transactions and rollback at the end of the unit test, so the db is clean", test db that is. What do you guys think of this testing + test DB + transaction rollback (so db is not really written) approach to test DAL?</p>
<p>To be complete, my DAL is built with Entity Framework, there is no stored proc in DB. Since EF is so new, I really need to test DAL to make sure they work correctly.</p>

<p>Trying to compile it with g++-4.3, it seems that <em>cv</em>-qualifier overloaded functions confuse both <code>tr1::mem_fn<></code> and <code>tr1::bind<></code> and it comes out the following error:</p>

310,363 | <p>I have a time represented as the number of seconds elapsed since midnight, January 1, 1970, UTC (the results of an earlier call to time()). How do I add one day to this time?</p>
<p>Adding 24 * 60 * 60 works in most cases, but fails if the daylight saving time comes on or off in between. In other words, I mostly want to add 24 hours, but sometimes 23 or 25 hours.</p>
<p>To illustrate - the program:</p>
<pre><code>#include <time.h>
#include <iostream>
int main()
{
time_t base = 1142085600;
for(int i = 0; i < 4; ++i) {
time_t time = base + i * 24 * 60 * 60;
std::cout << ctime(&time);
}
return 0;
</code></pre>
<p>}</p>
<p>Produces:</p>
<pre><code>Sat Mar 11 08:00:00 2006
Sun Mar 12 09:00:00 2006
Mon Mar 13 09:00:00 2006
Tue Mar 14 09:00:00 2006
</code></pre>
<p>I want the times for March 12, 13, ... to also be 8 AM.</p>
<hr>
<p>The answer provided by FigBug pointed me in the right direction. But I had to use localtime instead of gmtime.</p>
<pre><code>int main()
{
time_t base = 1142085600;
for(int i = 0; i < 4; ++i) {
struct tm* tm = localtime(&base);
tm->tm_mday += i;
std::cout << asctime(tm);
}
return 0;
}
</code></pre>
<p>Give me:</p>
<pre><code>Sat Mar 11 08:00:00 2006
Sat Mar 12 08:00:00 2006
Sat Mar 13 08:00:00 2006
Sat Mar 14 08:00:00 2006
</code></pre>
<p>Which is what I want. Using gmtime gives me the times at 14:00:00</p>
<p>However, note that all days are Sat. Also, it goes to March 32, 33, etc. If I throw in the mktime function I am back where I started:</p>
<pre><code>#include <time.h>
#include <iostream>
int main()
{
time_t base = 1142085600;
for(int i = 0; i < 4; ++i) {
struct tm* tm = localtime(&base);
tm->tm_mday += i;
time_t time = mktime(tm);
std::cout << asctime(tm);
}
return 0;
}
</code></pre>
<p>Gives me:</p>
<pre><code>Sat Mar 11 08:00:00 2006
Sun Mar 12 09:00:00 2006
Mon Mar 13 09:00:00 2006
Tue Mar 14 09:00:00 2006
</code></pre>
<p>What am I missing???</p>
<hr>
<p>OK, I have tried out FigBug's latest suggestion that is to use:</p>
<pre><code> std::cout << ctime(&time);
</code></pre>
<p>instead of asctime, but I get the same results. So I guess that my library and/or compiler is messed up. I am using g++ 3.4.4 on cygwin. I copied the files over to Solaris 5.8 and used g++ 3.3 there to compile. I get the correct results there! In fact I get the correct results whether I use ctime or asctime for output:</p>
<pre><code>Sat Mar 11 08:00:00 2006
Sun Mar 12 08:00:00 2006
Mon Mar 13 08:00:00 2006
Tue Mar 14 08:00:00 2006
</code></pre>
<p>I also get the correct results (with both output functions) on Red Hut Linux with g++ 3.4.6.</p>
<p>So I guess that I have come across a Cygwin bug. </p>
<p>Thank you for all your help and advice....</p>

<p>I don't mind them, and I have been using unordered lists in this way. It's just that, when I remove the styling from a page to try to gauge it's accessibility, it strikes me that it could just as well could be plain links. Where does this come from?</p>

310,394 | <p>I am still learning sql server somewhat and recently came across a select query in a stored procedure which was causing a very slow fill of a dataset in c#. At first I thought this was to do with .NET but then found a suggestion to put in the stored procedure:</p>
<p>set implicit_transactions off</p>
<p>this seems to cure it but I would like to know why also I have seen other options such as:</p>

310,408 | <p>Let's say we have a concrete <code>class Apple</code>. (Apple objects can be instantiated.)
Now, someone comes and derives an abstract <code>class Peach</code> from Apple. It's abstract because it introduces a new pure virtual function. The user of Peach is now forced to derive from it and define this new function. Is this a common pattern? Is this correct to do?</p>
<p>Sample:<pre><code>
class Apple
{
public:
virtual void MakePie();
// more stuff here
};</p>
<p>class Peach : public Apple
{
public:
virtual void MakeDeliciousDesserts() = 0;
// more stuff here
};</code></pre>
Now let's say we have a concrete <code>class Berry</code>. Someone derives an abstract <code>class Tomato</code> from Berry. It's abstract because it overwrites one of Berry's virtual functions, and makes it pure virtual. The user of Tomato has to re-implement the function previously defined in Berry. Is this a common pattern? Is this correct to do?</p>
<p>Sample:<pre><code>
class Berry
{
public:
virtual void EatYummyPie();
// more stuff here
};</p>
<p>class Tomato : public Berry
{
public:
virtual void EatYummyPie() = 0;
// more stuff here
};</code></pre>
Note: The names are contrived and do not reflect any actual code (hopefully). No fruits have been harmed in the writing of this question.</p>

310,425 | <p>Currently I have a table that I search upon 4 fields, FirstName, LastName, MiddleName, And AKA's. I currently have a <strong>CONTAINSTABLE</strong> search for the rows and it works. Not well but it works. Now <strong>I want to make the First Name weighted higher and middle name lower.</strong></p>
<p>I found the command <strong>ISABOUT</strong> but that seems pretty worthless if I have to do it by word not column (hopefully I understood this wrong). This is not an option if its by word because I do not know how many words the user will enter.</p>
<p>I found the thread <a href="https://stackoverflow.com/questions/198152/how-do-i-assign-weights-to-different-columns-in-a-full-text-search">here</a> that talks about this same solution however I was unable to get the accepted solution to work. Maybe I have done something wrong but regardless I cannot get it to work, and its logic seems really... odd. There has to be an easier way. </p>

310,436 | <p>Is there a way to only load child nodes when the parent node is expanded? The problem that I’m running into is that the “expand” icon doesn’t show up if a node doesn’t have any children. Since I don’t want to load the children until the icon is clicked, I’m left with a bit of a catch 22.</p>

<p>Can I create a two page PDF file from one .ps file using GhostScript? If so, what tells GhostScript where the page break should occur?</p>
<p>Maybe I need to use two template files. One for a one page pdf and another for a two page PDF.</p>

310,456 | <p>I'm trying to find a way to get the open tasks in C#. I've been searching on google and can only find how to get a list of the <strong>processes</strong>. I want the only the tasks that would show up on the taskbar.</p>
<p>Also, along with that, it would be cool if I could get the process the task is associated with. And if possible get the thumbnail images that Vista uses for the ALT-TAB menu, like in this image:</p>
<p><a href="https://i.stack.imgur.com/CcPQP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CcPQP.png" alt="alt-tab"></a></p>
<p>I assume that I will have to use pinvokes because it really doesn't look like there are any libraries to do this already. Any ideas?</p>

310,459 | <p>I'm trying to transform each element of a numpy array into an array itself (say, to interpret a greyscale image as a color image). In other words:</p>
<pre><code>>>> my_ar = numpy.array((0,5,10))
[0, 5, 10]
>>> transformed = my_fun(my_ar) # In reality, my_fun() would do something more useful
array([
[ 0, 0, 0],
[ 5, 10, 15],
[10, 20, 30]])
>>> transformed.shape
(3, 3)
</code></pre>
<p>I've tried:</p>
<pre><code>def my_fun_e(val):
return numpy.array((val, val*2, val*3))
my_fun = numpy.frompyfunc(my_fun_e, 1, 3)
</code></pre>
<p>but get:</p>
<pre><code>my_fun(my_ar)
(array([[0 0 0], [ 5 10 15], [10 20 30]], dtype=object), array([None, None, None], dtype=object), array([None, None, None], dtype=object))
</code></pre>
<p>and I've tried:</p>
<pre><code>my_fun = numpy.frompyfunc(my_fun_e, 1, 1)
</code></pre>
<p>but get:</p>
<pre><code>>>> my_fun(my_ar)
array([[0 0 0], [ 5 10 15], [10 20 30]], dtype=object)
</code></pre>
<p>This is close, but not quite right -- I get an array of objects, not an array of ints.</p>
<p><b>Update 3!</b> OK. I've realized that my example was too simple beforehand -- I don't just want to replicate my data in a third dimension, I'd like to transform it at the same time. Maybe this is clearer?</p>

310,479 | <p>I am developing a cocoa application that will be making heavy use of both web services and a standard dbms (most likely MySQL) and I am wondering if anyone has a good option for a database library or ORM solution they have used. CoreData is not an option due to the need to support a standard DBMS and to be able to modify the data outside of the normal application operation.</p>
<p>I have found a number of possible options from new open source libraries:
<a href="http://github.com/aptiva/activerecord/tree/master" rel="noreferrer">http://github.com/aptiva/activerecord/tree/master</a></p>
<p>To writing my own wrapper for the C MySQL api.</p>
<p>Any advice is welcome,</p>
<p>Thanks!</p>
