<p>Is there anyway to have a sort of virtual static member in C++?</p>
<p>For example:</p>
<pre><code>class BaseClass {
public:
BaseClass(const string& name) : _name(name) {}
string GetName() const { return _name; }
virtual void UseClass() = 0;
private:
const string _name;
};
class DerivedClass : public BaseClass {
public:
DerivedClass() : BaseClass("DerivedClass") {}
virtual void UseClass() { /* do something */ }
};
</code></pre>
<p>I know this example is trivial, but if I have a vector of complex data that is going to be always the same for all derived class but is needed to be accessed from base class methods?</p>
<pre><code>class BaseClass {
public:
BaseClass() {}
virtual string GetName() const = 0;
virtual void UseClass() = 0;
};
class DerivedClass : public BaseClass {
public:
DerivedClass() {}
virtual string GetName() const { return _name; }
virtual void UseClass() { /* do something */ }
private:
static const string _name;
};
string DerivedClass::_name = "DerivedClass";
</code></pre>
<p>This solution does not satify me because I need reimplement the member _name and its accessor GetName() in every class. In my case I have several members that follows _name behavior and tenths of derived classes.</p>
<p>Any idea?</p>

<p>We have a large database on which we have DB side pagination. This is quick, returning a page of 50 rows from millions of records in a small fraction of a second.</p>
<p>Users can define their own sort, basically choosing what column to sort by. Columns are dynamic - some have numeric values, some dates and some text.</p>
<p>While most sort as expected text sorts in a dumb way. Well, I say dumb, it makes sense to computers, but frustrates users.</p>
<p>For instance, sorting by a string record id gives something like:</p>
<pre><code>rec1
rec10
rec14
rec2
rec20
rec3
rec4
</code></pre>
<p>...and so on.</p>
<p>I want this to take account of the number, so:</p>
<pre><code>rec1
rec2
rec3
rec4
rec10
rec14
rec20
</code></pre>
<p>I can't control the input (otherwise I'd just format in leading 000s) and I can't rely on a single format - some are things like "{alpha code}-{dept code}-{rec id}".</p>
<p>I know a few ways to do this in C#, but can't pull down all the records to sort them, as that would be to slow.</p>
<p>Does anyone know a way to quickly apply a natural sort in Sql server?</p>
<hr>
<p>We're using:</p>
<pre><code>ROW_NUMBER() over (order by {field name} asc)
</code></pre>
<p>And then we're paging by that.</p>
<p>We can add triggers, although we wouldn't. All their input is parametrised and the like, but I can't change the format - if they put in "rec2" and "rec10" they expect them to be returned just like that, and in natural order.</p>
<hr>
<p>We have valid user input that follows different formats for different clients.</p>
<p>One might go rec1, rec2, rec3, ... rec100, rec101</p>
<p>While another might go: grp1rec1, grp1rec2, ... grp20rec300, grp20rec301</p>
<p>When I say we can't control the input I mean that we can't force users to change these standards - they have a value like grp1rec1 and I can't reformat it as grp01rec001, as that would be changing something used for lookups and linking to external systems.</p>
<p>These formats vary a lot, but are often mixtures of letters and numbers.</p>
<p>Sorting these in C# is easy - just break it up into <code>{ "grp", 20, "rec", 301 }</code> and then compare sequence values in turn.</p>
<p>However there may be millions of records and the data is paged, I need the sort to be done on the SQL server.</p>
<p>SQL server sorts by value, not comparison - in C# I can split the values out to compare, but in SQL I need some logic that (very quickly) gets a single value that consistently sorts.</p>
<p>@moebius - your answer might work, but it does feel like an ugly compromise to add a sort-key for all these text values.</p>

<p>When writing multi-threaded applications, one of the most common problems experienced are deadlocks. </p>
<p>My questions to the community are:</p>
<ol>
<li><p>What is a deadlock? </p></li>
<li><p>How do you detect them? </p></li>
<li><p>Do you handle them? </p></li>
<li><p>And finally, how do you prevent them from occurring?</p></li>
</ol>

<p>This most be the second most simple rollover effect, still I don't find any simple solution.</p>
<p><strong>Wanted:</strong> I have a list of items and a corresponding list of slides (DIVs). After loading, the first list item should be selected (bold) and the first slide should be visible. When the user hovers over another list item, that list item should be selected instead and the corresponding slide be shown.</p>
<p>The following code works, but <em>is awful</em>. How can I get this behaviour in an elegant way? jquery has dozens of animated and complicated rollover effects, but I didn't come up with a clean way for this effect.</p>
<pre><code><script type="text/javascript">
function switchTo(id) {
document.getElementById('slide1').style.display=(id==1)?'block':'none';
document.getElementById('slide2').style.display=(id==2)?'block':'none';
document.getElementById('slide3').style.display=(id==3)?'block':'none';
document.getElementById('slide4').style.display=(id==4)?'block':'none';
document.getElementById('switch1').style.fontWeight=(id==1)?'bold':'normal';
document.getElementById('switch2').style.fontWeight=(id==2)?'bold':'normal';
document.getElementById('switch3').style.fontWeight=(id==3)?'bold':'normal';
document.getElementById('switch4').style.fontWeight=(id==4)?'bold':'normal';
}
</script>
<ul id="switches">
<li id="switch1" onmouseover="switchTo(1);" style="font-weight:bold;">First slide</li>
<li id="switch2" onmouseover="switchTo(2);">Second slide</li>
<li id="switch3" onmouseover="switchTo(3);">Third slide</li>
<li id="switch4" onmouseover="switchTo(4);">Fourth slide</li>
</ul>
<div id="slides">
<div id="slide1">Well well.</div>
<div id="slide2" style="display:none;">Oh no!</div>
<div id="slide3" style="display:none;">You again?</div>
<div id="slide4" style="display:none;">I'm gone!</div>
</div>
</code></pre>

<p>How do I use JUnit to test a class that has internal private methods, fields or nested classes?</p>
<p>It seems bad to change the access modifier for a method just to be able to run a test.</p>

<p>I've recently been working with a MySQL database, and using MySQL workbench to design the Database.</p>
<p>When I use the export to SQL function, so I can actually get the layout in to the Database, I get:</p>
<blockquote>
<p>"Error 1005: Cannot create table"</p>
</blockquote>
<p>This appears to be related to Foreign Keys in the create table statement.</p>
<p>Does anybody have a work around for this that doesn't involve taking the constraints out and putting them back in later? That's a less than ideal solution given the size of the database.</p>

<p>I expected the two <code>span</code> tags in the following sample to display next to each other, instead they display one below the other. If I set the <code>width</code> of the class <code>span</code>.right to 49% they display next to each other. I am not able to figure out why the right span is pushed down like the right span has some invisible <code>padding/margin</code> which makes it take more than 50%. I am trying to get this done without using html tables. Any ideas?</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>* {
margin: 0;
}
html,
body {
margin: 0;
padding: 0;
height: 100%;
width: 100%;
border: none;
}
div.header {
width: 100%;
height: 80px;
vertical-align: top;
}
span.left {
height: 80px;
width: 50%;
display: inline-block;
background-color: pink;
}
span.right {
vertical-align: top;
display: inline-block;
text-align: right;
height: 80px;
width: 50%;
background-color: red;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><html>
<head>
<title>Test Page</title>
</head>
<body>
<div class='header'>
<span class='left'>Left Span 50% width</span>
<span class='right'>Right Span 50% width</span>
</div>
</body>
</html></code></pre>
</div>
</div>
</p>
<hr />
<p>Thanks for the explanation. The <code>float:left</code> works beautifully with expected results in FF 3.1. Unfortunately, in IE6 the right side span renders 50% of the 50%, in effect giving it a width of 25% of the browser window. Setting its width to 100% achieves the desired results but breaks in FF 3.1 which is in standards compliance mode and I understand that. Getting it to work both in FF and IE 6, without resorting to hacks or using multiple CSS sheets has been a challenge</p>

<p>When running my application I sometimes get an error about <code>too many files open</code>.</p>
<p>Running <code>ulimit -a</code> reports that the limit is 1024. How do I increase the limit above 1024? </p>
<p><strong>Edit</strong>
<code>ulimit -n 2048</code> results in a permission error.</p>

<p>What is a good Hash function? I saw a lot of hash function and applications in my data structures courses in college, but I mostly got that it's pretty hard to make a good hash function. As a rule of thumb to avoid collisions my professor said that:</p>
<pre><code>function Hash(key)
return key mod PrimeNumber
end
</code></pre>
<p>(mod is the % operator in C and similar languages)</p>
<p>with the prime number to be the size of the hash table. I get that is a somewhat good function to avoid collisions and a fast one, but how can I make a better one? Is there better hash functions for string keys against numeric keys?</p>

<p>The system I am currently working on requires some role-based security, which is well catered for in the Java EE stack. The system intends to be a framework for business domain experts to write their code on top of.</p>
<p>However, there is also a requirement for data <code>security</code>. That is, what information is visible to an end user.</p>
<p>This effectively means reducing visibility to rows (and perhaps even columns) in the database.</p>
<p>We are using Hibernate for our persistence. However, we are using our own annotations so as not to expose our persistence choice to the business domain experts. </p>
<p>For row based security this means we could add an annotation such as <code>@Secured</code> at the entity level, which would cause an extra column to be added to the underlying table to constrain our selects?</p>
<p>For column based security, we could perhaps have <code>@Secured</code> to either assist in query generation, or perhaps use an aspect to filter the information returned?</p>
<p>I'm curious to know how this might affect hibernate's caching mechanisms as well?</p>
<p>I'm sure a lot of others will have had the same issue, and I was wondering how you approached this?</p>
<p>Much appreciated...</p>

<p>I have an application that sends messages to an external web service. I build and deploy this application using <a href="http://msdn.microsoft.com/en-us/library/wea2sca5(VS.80).aspx" rel="nofollow noreferrer">MSBuild</a> and <a href="http://confluence.public.thoughtworks.org/display/CCNET/Welcome+to+CruiseControl.NET" rel="nofollow noreferrer">Cruisecontrol.NET</a>. As CCNET build and deploys the app it also runs a set of test using <a href="http://www.nunit.org/index.php" rel="nofollow noreferrer">NUnit</a>. I'd now like to test the web service communication as well. </p>
<p>My idea is that as part of the build process a web service should be generated (based on the external web services WSDL) and deployed to the build servers local web server. All the web service should do is to receive the message and place it on the file system so I then can check it using ordinary NUnit for example. This would also make development easier as new developers would only have to run the build script and be up and running (not have to spend time to set up a connection to the third party service). </p>
<p>Are there any <strong>existing utilities out there</strong> that easily mock a web service based on a WSDL? Anyone <strong>done something similar using MSBuild?</strong> </p>
<p>Are there <strong>other ways of testing this scenario?</strong> </p>

<p>Has anyone found a useful solution to the DesignMode problem when developing controls?</p>
<p>The issue is that if you nest controls then DesignMode only works for the first level. The second and lower levels DesignMode will always return FALSE.</p>
<p>The standard hack has been to look at the name of the process that is running and if it is "DevEnv.EXE" then it must be studio thus DesignMode is really TRUE.</p>
<p>The problem with that is looking for the ProcessName works its way around through the registry and other strange parts with the end result that the user might not have the required rights to see the process name. In addition this strange route is very slow. So we have had to pile additional hacks to use a singleton and if an error is thrown when asking for the process name then assume that DesignMode is FALSE.</p>
<p>A nice clean way to determine DesignMode is in order. Acually getting Microsoft to fix it internally to the framework would be even better!</p>

<p>I have a recursive algorithm which steps through a string, character by character, and parses it to create a tree-like structure. I want to be able to keep track of the character index the parser is currently at (for error messages as much as anything else) but am not keen on implementing something like a tuple to handle multiple returned types.</p>
<p>I tried using an Integer type, declared outside the method and passed into the recursive method, but because it's final, recursive call increments are "forgotten" when I return. (Because the increment of the Integer value makes the passed-by-value object reference point at a new object)</p>
<p>Is there a way to get something similar to work which won't pollute my code?</p>

<p>You can use a standard dot notation or a method call in Objective-C to access a property of an object in Objective-C.</p>
<pre><code>myObject.property = YES;
</code></pre>
<p>or</p>
<pre><code>[myObject setProperty:YES];
</code></pre>
<p>Is there a difference in performance (in terms of accessing the property)? Is it just a matter of preference in terms of coding style?</p>

<p>When I try to do any svn command and supply the <code>--username</code> and/or <code>--password</code> options, it prompts me for my password anyways, and always will attempt to use my current user instead of the one specified by <code>--username</code>. Neither <code>--no-auth-cache</code> nor <code>--non-interactive</code> have any effect on this. This is a problem because I'm trying to call svn commands from a script, and I can't have it show the prompt.</p>
<p>For example, logged in as user1:</p>
<pre><code># $ svn update --username 'user2' --password 'password'
# [email protected]'s password:
</code></pre>
<p>Other options work correctly:</p>
<pre><code># $ svn --version --quiet
# 1.3.2
</code></pre>
<p>Why does it prompt me?<br>
And why is it asking for user1's password instead of user2's?<br>
I'm 99% sure all of my permissions are set correctly. Is there some config option for svn that switches off command-line passwords?<br>
Or is it something else entirely?</p>
<p>I'm running svn 1.3.2 (r19776) on Fedora Core 5 (Bordeaux).</p>

<p>We have an application with a good amount of jQuery JSON calls to server side code. Because of this, we have a large amount of binding code to parse responses and bind the appropriate values to the form. This is a two part question.</p>
<ol>
<li><p>What is the reccomended approach for dealing with a large number of forms that all have different data. Right now were are trying to take a structured approach in setting up a js "class" for each page, with an init, wireClickEvents etc.. to try to have everything conformed.</p></li>
<li><p>Is there any "best practices" with creating repetitive jQuery code or any type of reccomended structure other than just throwing a bunch of functions in a js file?</p></li>

<p>A few months back I was tasked with implementing a unique and random code for our web application. The code would have to be user friendly and as small as possible, but still be essentially random (so users couldn't easily predict the next code in the sequence).</p>
<p>It ended up generating values that looked something like this:</p>
<pre><code>Af3nT5Xf2
</code></pre>
<p>Unfortunately, I was never satisfied with the implementation. Guid's were out of the question, they were simply too big and difficult for users to type in. I was hoping for something more along the lines of 4 or 5 characters/digits, but our particular implementation would generate noticeably patterned sequences if we encoded to less than 9 characters.</p>
<p>Here's what we ended up doing:</p>
<p>We pulled a unique sequential 32bit id from the database. We then inserted it into the center bits of a 64bit RANDOM integer. We created a lookup table of easily typed and recognized characters (A-Z, a-z, 2-9 skipping easily confused characters such as L,l,1,O,0, etc.). Finally, we used that lookup table to base-54 encode the 64-bit integer. The high bits were random, the low bits were random, but the center bits were sequential.</p>
<p>The final result was a code that was much smaller than a guid and looked random, even though it absolutely wasn't.</p>
<p>I was never satisfied with this particular implementation. What would you guys have done?</p>

<p>I have some UI in VB 2005 that looks great in XP Style, but goes hideous in Classic Style.</p>
<p>Any ideas about how to detect which mode the user is in and re-format the forms on the fly?</p>
<hr>
<p>Post Answer Edit:</p>
<p>Thanks Daniel, looks like this will work. I'm using the first solution you posted with the GetCurrentThemeName() function.</p>
<p>I'm doing the following:</p>
<p><strong>Function Declaration:</strong>
<pre><code> Private Declare Unicode Function GetCurrentThemeName Lib "uxtheme" (ByVal stringThemeName As System.Text.StringBuilder, ByVal lengthThemeName As Integer, ByVal stringColorName As System.Text.StringBuilder, ByVal lengthColorName As Integer, ByVal stringSizeName As System.Text.StringBuilder, ByVal lengthSizeName As Integer) As Int32
</pre></code></p>
<p><strong><em>Code Body:</em></strong>
<pre><code>
Dim stringThemeName As New System.Text.StringBuilder(260)
Dim stringColorName As New System.Text.StringBuilder(260)
Dim stringSizeName As New System.Text.StringBuilder(260)</p>
<p>GetCurrentThemeName(stringThemeName, 260, stringColorName, 260, stringSizeName, 260)
MsgBox(stringThemeName.ToString)
</pre></code></p>
<p>The MessageBox comes up Empty when i'm in Windows Classic Style/theme, and Comes up with "C:\WINDOWS\resources\Themes\luna\luna.msstyles" if it's in Windows XP style/theme. I'll have to do a little more checking to see what happens if the user sets another theme than these two, but shouldn't be a big issue.</p>

<p>I've tried two different methods of reusing code. I have a solution full of just class library projects with generic code that I reuse in almost every project I work on. When I get to work on a new project, I will reuse code from this code library in one of two ways:</p>
<ol>
<li>I have tried bringing the projects I need from this code library into my project.</li>
<li>I have also tried compiling down to a .dll and referencing the .dll from a folder in the root of my current solution.</li>
</ol>
<p>While the second method seems easier and lighter to implement, I always find myself making small tweaks to the original code to fit it into the context of my current project.</p>
<p>I know this is a bit of a vague question, but has anyone had success with other methods of reusing class libraries on new solutions?</p>

<p>I'm having trouble getting a rotary encoder to work properly with AVR micro controllers. The encoder is a mechanical <a href="http://no.farnell.com/1520815/passives/product.us0?sku=alps-ec12d1524401" rel="noreferrer">ALPS encoder</a>, and I'm using <a href="http://www.atmel.com/dyn/resources/prod_documents/doc2545.pdf" rel="noreferrer">Atmega168</a>.</p>
<p><strong>Clarification</strong></p>
<p>I have tried using an External Interrupt to listen to the pins, but it seems like it is too slow. When Pin A goes high, the interrupt procedure starts and then checks if Pin B is high. The idea is that if Pin B is high the moment Pin A went high, then it is rotating counter clock-wise. If Pin B is low, then it is rotating clock-wise. But it seems like the AVR takes too long to check Pin B, so it is always read as high. </p>
<p>I've also tried to create a program that simply blocks until Pin B or Pin A changes. But it might be that there is too much noise when the encoder is rotated, because this does not work either. My last attempt was to have a timer which stores the last 8 values in a buffer and checks if it is going from low to high. This did not work either.</p>
<p>I have tried scoping the encoder, and it seems to use between 2 and 4ms from the first Pin changes till the other Pin changes.</p>

<p>I have recently installed .net 3.5 SP1. When I deployed a compiled web site that contained a form with its action set:</p>
<pre><code><form id="theForm" runat="server" action="post.aspx">
</code></pre>
<p>I received this error.<br>
Method not found: 'Void System.Web.UI.HtmlControls.HtmlForm.set_Action(System.String)'.<br>
If a fellow developer who has not installed SP1 deploys the compiled site it works fine. Does anyone know of any solutions for this?</p>

<p>What is a good setup for .hgignore file when working with Visual Studio 2008?</p>
<p>I mostly develop on my own, only occasionly I clone the repository for somebody else to work on it.</p>
<p>I'm thinking about obj folders, .suo, .sln, .user files etc.. Can they just be included or are there file I shouldn't include?</p>
<p>Thanks!</p>
<p>p.s.: at the moment I do the following : ignore all .pdb files and all obj folders.</p>
<pre><code># regexp syntax.
syntax: glob
*.pdb
syntax: regexp
/obj/
</code></pre>

<p>The <code>datepicker</code> function only works on the first input box that is created.</p>
<p>I'm trying to duplicate a datepicker by cloning the <code>div</code> that is containing it.</p>
<pre><code><a href="#" id="dupMe">click</a>
<div id="template">
input-text <input type="text" value="text1" id="txt" />
date time picker <input type="text" id="example" value="(add date)" />
</div>
</code></pre>
<p>To initialize the datepicker, according to the <a href="http://docs.jquery.com/UI/Datepicker" rel="nofollow noreferrer">jQuery UI documentation</a> I only have to do <code>$('#example').datepicker();</code> and it does work, but only on the first datepicker that is created.</p>
<p>The code to duplicate the <code>div</code> is the following:</p>
<pre><code>$("a#dupMe").click(function(event){
event.preventDefault();
i++;
var a = $("#template")
.clone(true)
.insertBefore("#template")
.hide()
.fadeIn(1000);
a.find("input#txt").attr('value', i);
a.find("input#example").datepicker();
});
</code></pre>
<p>The strangest thing is that on the <code>document.ready</code> I have:</p>
<pre><code>$('#template #example').datepicker();
$("#template #txt").click(function() { alert($(this).val()); });
</code></pre>
<p>and if I click on the <code>#txt</code> it always works.</p>

<p>I have a gridview that is within an updatepanel for a modal popup I have on a page.<br>
The issue is that the entire page refreshes every time I click an imagebutton that is within my gridview. This causes my entire page to load and since I have grayed out the rest of the page so that the user cannot click on it this is very annoying.</p>
<p>Does any one know what I am missing. </p>
<p><strong>Edit:</strong> I entered a better solution at the bottom</p>

<p>I'm trying to write a custom WPF ValidationRule to enforce that a certain property is unique within the context of a given collection. For example: I am editing a collection of custom objects bound to a ListView and I need to ensure that the Name property of each object in the collection is unique. Does anyone know how to do this?</p>

<p>I have a little dilemma that maybe you can help me sort out. </p>
<p>I've been working today in modifying ASP.NET's Membership to add a level of indirection. Basically, ASP.NET's Membership supports Users and Roles, leaving all authorization rules to be based on whether a user belongs to a Role or not. </p>
<p>What I need to do is add the concept of Function, where a user will belong to a role (or roles) and the role will have one or more functions associated with them, allowing us to authorize a specific action based on if the user belongs to a role which has a function assigned. </p>
<p>Having said that, my problem has nothing to do with it, it's a generic class design issue. </p>
<p>I want to provide an abstract method in my base RoleProvider class to create the function (and persist it), but I want to make it optional to save a description for that function, so I need to create my CreateFunction method with an overload, one signature accepting the name, and the other accepting the name and the description. </p>
<p>I can think of the following scenarios: </p>
<ol>
<li><p>Create both signatures with the abstract modifier. This has the problem that the implementer may not respect the best practice that says that one overload should call the other one with the parameters normalized, and the logic should only be in the final one (the one with all the parameters). Besides, it's not nice to require both methods to be implemented by the developer. </p></li>
<li><p>Create the first like virtual, and the second like abstract. Call the second from the first, allow the implementer to override the behavior. It has the same problem, the implementer could make "bad decisions" when overriding it. </p></li>
<li><p>Same as before, but do not allow the first to be overriden (remove the virtual modifier). The problem here is that the implementer has to be aware that the method could be called with a null description and has to handle that situation. </p></li>
</ol>
<p>I think the best option is the third one... </p>
<p>How is this scenario handled in general? When you design an abstract class and it contains overloaded methods. It isn't that uncommon I think... </p>

<p>In terms of performance and optimizations:</p>
<ul>
<li>When constructing a table in SQL Server, does it matter what order I put the columns in?</li>
<li>Does it matter if my primary key is the first column?</li>
<li>When constructing a multi-field index, does it matter if the columns are adjacent?</li>
<li>Using ALTER TABLE syntax, is it possible to specify in what position I want to add a column?
<ul>
<li>If not, how can I move a column to a difference position?</li>

<p>When using a <code>Zend_Form</code>, the only way to validate that an input is not left blank is to do</p>
<pre><code>$element->setRequired(true);
</code></pre>
<p>If this is not set and the element is blank, it appears to me that validation is not run on the element.</p>
<p>If I do use <code>setRequired()</code>, the element is automatically given the standard NotEmpty validator. The thing is that the error message with this validator sucks, "Value is empty, but a non-empty value is required". I want to change this message. At the moment I have done this by changing the <code>Zend_Validate_NotEmpty</code> class, but this is a bit hacky.</p>
<p>I would ideally like to be able to use my own class (derived from <code>Zend_Validate_NotEmpty</code>) to perform the not empty check.</p>

<p>In the PHP manual, to show the syntax for functions with optional parameters, they use brackets around each set of dependent optional parameter. For example, for the <a href="http://php.net/date" rel="noreferrer"><code>date()</code></a> function, the manual reads:</p>
<pre><code>string date ( string $format [, int $timestamp = time() ] )
</code></pre>
<p>Where <code>$timestamp</code> is an optional parameter, and when left blank it defaults to the <a href="http://php.net/time" rel="noreferrer"><code>time()</code></a> function's return value.</p>
<p>How do you go about creating optional parameters like this when defining a custom function in PHP?</p>

<p>I'm experimenting with Linq and am having trouble figuring out grouping. I've gone through several tutorials but for some reason can't figure this out.</p>
<p>As an example, say I have a table (SiteStats) with multiple website IDs that stores a count of how many visitors by type have accessed each site in total and for the past 30 days.</p>
<pre><code>╔════════╦═════════════╦════════╦══════╗
║ SiteId ║ VisitorType ║ Last30 ║ Total║
╠════════╬═════════════╬════════╬══════╣
║ 1 ║ 1 ║ 10 ║ 100 ║
║ 1 ║ 2 ║ 40 ║ 140 ║
║ 2 ║ 1 ║ 20 ║ 180 ║
╚════════╩═════════════╩════════╩══════╝
</code></pre>
<p>In SQL, I can easily get the counts for SiteID 1 with the following:</p>
<pre><code>SELECT SiteId,
SUM(Last30) AS Last30Sum
FROM Sites
WHERE SiteId = 1
GROUP BY SiteId
</code></pre>
<p>and should get a row like...</p>
<pre><code>╔════════╦════════════╗
║ SiteId ║ Last30Total║
╠════════╬════════════╣
║ 1 ║ 50 ║
╚════════╩════════════╝
</code></pre>
<p>However I'm not sure how to get this result using Linq. I've tried:</p>
<pre><code>var statsRecord = from ss in db.SiteStats
where ss.SiteId == siteId
group ss by ss.SiteId into ss
select ss;
</code></pre>
<p>but I'm not able to get back the total with something like <code>statsRecord.Last30</code></p>
<p>Can someone please let me know where I'm going wrong? Any help is appreciated.</p>

<p>What is the best way to create a lock on a file in Perl?</p>
<p>Is it best to flock on the file or to create a lock file to place a lock on and check for a lock on the lock file?</p>

<p>I've seen quite a few posts on changes in .NET 3.5 SP1, but stumbled into one that I've yet to see documentation for yesterday. I had code working just fine on my machine, from VS, msbuild command line, everything, but it failed on the build server (running .NET 3.5 RTM).</p>
<pre><code>[XmlRoot("foo")]
public class Foo
{
static void Main()
{
XmlSerializer serializer = new XmlSerializer(typeof(Foo));
string xml = @"<foo name='ack' />";
using (StringReader sr = new StringReader(xml))
{
Foo foo = serializer.Deserialize(sr) as Foo;
}
}
[XmlAttribute("name")]
public string Name { get; set; }
public Foo Bar { get; private set; }
}
</code></pre>
<p>In SP1, the above code runs just fine. In RTM, you get an InvalidOperationException:</p>
<blockquote>
<p>Unable to generate a temporary class (result=1).
error CS0200: Property or indexer 'ConsoleApplication2.Foo.Bar' cannot be assign to -- it is read only</p>
</blockquote>
<p>Of course, all that's needed to make it run under RTM is adding [XmlIgnore] to the Bar property.</p>
<p>My google fu is apparently not up to finding documentation of these kinds of changes. Is there a change list anywhere that lists this change (and similar under-the-hood changes that might jump up and shout "gotcha")? Is this a bug or a feature? </p>
<p><strong>EDIT</strong>: In SP1, if I added a <code><Bar /></code> element, or set [XmlElement] for the Bar property, it won't get deserialized. It doesn't fail pre-SP1 when it tries to deserialize--it throws an exception when the XmlSerializer is constructed.</p>
<p>This makes me lean more toward it being a bug, especially if I set an [XmlElement] attribute for Foo.Bar. If it's unable to do what I ask it to do, it should be throwing an exception instead of silently ignoring Foo.Bar. Other invalid combinations/settings of XML serialization attributes result in an exception.</p>
<p><strong>EDIT</strong>: Thank you, TonyB, I'd not known about setting the temp files location. For those that come across similar issues in the future, you do need an additional config flag:</p>
<pre><code><system.diagnostics>
<switches>
<add name="XmlSerialization.Compilation" value="1" />
</switches>
</system.diagnostics>
<system.xml.serialization>
<xmlSerializer tempFilesLocation="c:\\foo"/>
</system.xml.serialization>
</code></pre>
<p>Even with setting an [XmlElement] attribute on the Bar property, no mention was made of it in the generated serialization assembly--which fairly firmly puts this in the realm of a silently swallowed error (aka, a bug). Either that or the designers have decided [XmlIgnore] is no longer necessary for properties that can't be set--and you'd expect to see that in release notes, <a href="http://support.microsoft.com/kb/951847" rel="nofollow noreferrer">change lists</a>, or the <a href="http://msdn.microsoft.com/en-us/library/system.xml.serialization.xmlignoreattribute.aspx" rel="nofollow noreferrer">XmlIgnoreAttribute documentation</a>.</p>

<p>I have an if statement with two conditions (separated by an OR operator), one of the conditions covers +70% of situations and takes far less time to process/execute than the second condition, so in the interests of speed I only want the second condition to be processed if the first condition evaluates to false.</p>
<p>if I order the conditions so that the first condition (the quicker one) appears in the if statement first - on the occasions where this condition is met and evaluates true is the second condition even processed?</p>
<pre><code>if ( (condition1) | (condition2) ){
// do this
}
</code></pre>
<p>or would I need to nest two if statements to only check the second condition if the first evaluates to false?</p>
<pre><code>if (condition1){
// do this
}else if (condition2){
// do this
}
</code></pre>
<p>I am working in PHP, however, I assume that this may be language-agnostic.</p>

<p>When building projects in C++, I've found debugging linking errors to be tricky, especially when picking up other people's code. What strategies do people use for debugging and fixing linking errors?</p>

<p>The company I work for is starting to have issues with their current branching model and I was wondering what different kinds of branching strategies the community has been exposed to?</p>
<p>Are there any good ones for different situations? What does your company use? What are the advantages and disadvantages of them??</p>

<p>I have a protocol that requires a length field up to 32-bits, and it must be
generated at runtime to describe how many bytes are in a given packet.</p>
<p>The code below is kind of ugly but I am wondering if this can be refactored to
be slightly more efficient or easily understandable. The problem is that the
code will only generate enough bytes to describe the length of the packet, so
less than 255 bytes = 1 byte of length, less than 65535 = 2 bytes of length
etc...</p>
<pre><code>{
extern char byte_stream[];
int bytes = offset_in_packet;
int n = length_of_packet;
/* Under 4 billion, so this can be represented in 32 bits. */
int t;
/* 32-bit number used for temporary storage. */
/* These are the bytes we will break up n into. */
unsigned char first, second, third, fourth;
t = n & 0xFF000000;
/* We have used AND to "mask out" the first byte of the number. */
/* The only bits which can be on in t are the first 8 bits. */
first = t >> 24;
if (t) {
printf("byte 1: 0x%02x\n",first );
byte_stream[bytes] = first; bytes++;
write_zeros = 1;
}
/* Now we shift t so that it is between 0 and 255. This is the first, highest byte of n. */
t = n & 0x00FF0000;
second = t >> 16;
if (t || write_zeros) {
printf("byte 2: 0x%02x\n", second );
byte_stream[bytes] = second; bytes++;
write_zeros = 1;
}
t = n & 0x0000FF00;
third = t >> 8;
if ( t || write_zeros) {
printf("byte 3: 0x%02x\n", third );
byte_stream[bytes] = third; bytes++;
write_zeros = 1;
}
t = n & 0x000000FF;
fourth = t;
if (t || write_zeros) {
printf("byte 4: 0x%02x\n", fourth);
byte_stream[bytes] = fourth; bytes++;
}
}

<p>I am trying to iterate over all the elements of a static array of strings in the best possible way. I want to be able to declare it on one line and easily add/remove elements from it without having to keep track of the number. Sounds really simple, doesn't it?</p>
<p>Possible non-solutions:</p>
<pre><code>vector<string> v;
v.push_back("abc");
b.push_back("xyz");
for(int i = 0; i < v.size(); i++)
cout << v[i] << endl;
</code></pre>
<p>Problems - no way to create the vector on one line with a list of strings</p>
<p>Possible non-solution 2:</p>
<pre><code>string list[] = {"abc", "xyz"};
</code></pre>
<p>Problems - no way to get the number of strings automatically (that I know of).</p>
<p>There must be an easy way of doing this.</p>

<p><strong>Is there anything built into the core C# libraries that can give me an immutable Dictionary?</strong> </p>
<p>Something along the lines of <em>Java's</em>:</p>
<pre><code>Collections.unmodifiableMap(myMap);
</code></pre>
<p>And just to clarify, I am not looking to stop the keys / values themselves from being changed, just the structure of the Dictionary. I want something that fails fast and loud if any of IDictionary's mutator methods are called (<code>Add, Remove, Clear</code>).</p>

<p>Every time I create an object that has a collection property I go back and forth on the best way to do it?</p>
<ol>
<li>public property with a getter that
returns a reference to private variable</li>
<li>explicit get_ObjList and set_ObjList
methods that return and create new or cloned
objects every time</li>
<li>explicit get_ObjList that returns an
IEnumerator and a set_ObjList that
takes IEnumerator</li>
</ol>
<p>Does it make a difference if the collection is an array (i.e., objList.Clone()) versus a List?</p>
<p>If returning the actual collection as a reference is so bad because it creates dependencies, then why return any property as a reference? Anytime you expose an child object as a reference the internals of that child can be changed without the parent "knowing" unless the child has a property changed event. Is there a risk for memory leaks?</p>
<p>And, don't options 2 and 3 break serialization? Is this a catch 22 or do you have to implement custom serialization anytime you have a collection property?</p>
<p>The generic ReadOnlyCollection seems like a nice compromise for general use. It wraps an IList and restricts access to it. Maybe this helps with memory leaks and serialization. However it still has <a href="http://www.coversant.net/Coversant/Blogs/tabid/88/EntryID/34/Default.aspx" rel="noreferrer">enumeration concerns</a> </p>
<p>Maybe it just depends. If you don't care that the collection is modified, then just expose it as a public accessor over a private variable per #1. If you don't want other programs to modify the collection then #2 and/or #3 is better.</p>
<p>Implicit in the question is why should one method be used over another and what are the ramifications on security, memory, serialization, etc.?</p>

<p>I've got a whole directory of dll's I need to register to the GAC. I'd like to avoid registering each file explicitly- but it appears that gacutil has no "register directory" option. Anyone have a fast/simple solution?</p>

<p>I need to convert a named instance of SQL server 2005, to a default instance.</p>
<p>Is there a way to do this without a reinstall?</p>
<hr>
<p>The problem is, 2 out of 6 of the developers, installed with a named instance. So its becoming a pain changing connection strings for the other 4 of us. I am looking for the path of least resistance to getting these 2 back on to our teams standard setup. </p>
<p>Each has expressed that this is going to be, too much trouble and that it will take away from their development time. I assumed that it would take some time to resolve, in the best interest of all involved, I tried combing through configuration apps installed and didn't see anything, so I figured someone with more knowledge of the inner workings would be here.</p>

<p>I have a directory with PDF files that I need to create an index for. It is a PHP page with a list of links:</p>
<pre><code><A HREF="path to file">filename</A>
</code></pre>
<p>The filenames can be complicated:</p>
<pre><code>LVD 2-1133 - Ändring av dumpningslina (1984-11-20).pdf
</code></pre>
<p>What is the correct way to link to this file on a Linux/Apache server?</p>
<p>Is there a PHP function to do this conversion?</p>

<p>Perhaps the biggest risk in pushing new functionality to live lies with the database modifications required by the new code. In Rails, I believe they have 'migrations', in which you can programmatically make changes to your development host, and then make the same changes live along with the code that uses the revised schema. And roll both backs if needs be, in a synchronized fashion.</p>
<p>Has anyone come across a similar toolset for PHP/MySQL? Would love to hear about it, or any programmatic or process solutions to help make this less risky...</p>

<p>Thus, can anybody <br />
A) Give a rundown of the differences or <br />
B) Point me (and others like me) somewhere that has such a list.

<p>I'm working with a SQL Server 2000 database that likely has a few dozen tables that are no longer accessed. I'd like to clear out the data that we no longer need to be maintaining, but I'm not sure how to identify which tables to remove.</p>
<p>The database is shared by several different applications, so I can't be 100% confident that reviewing these will give me a complete list of the objects that are used.</p>
<p>What I'd like to do, if it's possible, is to get a list of tables that haven't been accessed at all for some period of time. No reads, no writes. How should I approach this?</p>

<p>I'd like to bind a configuration file to my executable. I'd like to do this by storing an MD5 hash of the file inside the executable. This should keep anyone but the executable from modifying the file.</p>
<p>Essentially if someone modifies this file outside of the program the program should fail to load it again.</p>
<p>EDIT: The program processes credit card information so being able to change the configuration in any way could be a potential security risk. This software will be distributed to a large number of clients. Ideally client should have a configuration that is tied directly to the executable. This will hopefully keep a hacker from being able to get a fake configuration into place.</p>
<p>The configuration still needs to be editable though so compiling an individual copy for each customer is not an option.</p>
<hr>
<p>It's important that this be dynamic. So that I can tie the hash to the configuration file as the configuration changes.</p>

<p>I've found <a href="http://msdn.microsoft.com/en-us/library/system.web.configuration.scriptingjsonserializationsection.scriptingjsonserializationsection.aspx" rel="noreferrer"><code>ScriptingJsonSerializationSection</code></a> but I'm not sure how to use it. I could write a function to convert the object to a JSON string manually, but since .Net can do it on the fly with the <code><System.Web.Services.WebMethod()></code> and <code><System.Web.Script.Services.ScriptMethod()></code> attributes so there must be a built-in way that I'm missing. </p>
<p>PS: using Asp.Net 2.0 and VB.Net - I put this in the tags but I think people missed it.</p>

<p>What did I do wrong?</p>
<p>Here is an excerpt from my code:</p>
<pre><code>public void createPartControl(Composite parent) {
parent.setLayout(new FillLayout());
ScrolledComposite scrollBox = new ScrolledComposite(parent, SWT.V_SCROLL);
scrollBox.setExpandHorizontal(true);
mParent = new Composite(scrollBox, SWT.NONE);
scrollBox.setContent(mParent);
FormLayout layout = new FormLayout();
mParent.setLayout(layout);
// Adds a bunch of controls here
mParent.layout();
mParent.setSize(mParent.computeSize(SWT.DEFAULT, SWT.DEFAULT, true));
}
</code></pre>
<p>...but it clips the last button:
<img src="https://i.stack.imgur.com/1ubzc.png" alt="alt text" title="Screenshot"></p>
<p>bigbrother82: That didn't work.</p>
<p>SCdF: I tried your suggestion, and now the scrollbars are gone. I need to work some more on that.</p>

<p>I know that the following is true</p>
<pre><code>int i = 17; //binary 10001
int j = i << 1; //decimal 34, binary 100010
</code></pre>
<p>But, if you shift too far, the bits fall off the end. Where this happens is a matter of the size of integer you are working with.</p>
<p>Is there a way to perform a shift so that the bits rotate around to the other side? I'm looking for a single operation, not a for loop.</p>

<p>I am working on a C++ code base that was recently moved from X/Motif to Qt. I am trying to write a Perl script that will replace all occurrences of Boolean (from X) with bool. The script just does a simple replacement. </p>
<pre><code>s/\bBoolean\b/bool/g
</code></pre>
<p>There are a few conditions. </p>
<p>1) We have CORBA in our code and \b matches CORBA::Boolean which should <strong>not</strong> be changed.<br>
2) It should not match if it was found as a string (i.e. "Boolean")</p>
<p><strong>Updated:</strong></p>
<p>For #1, I used lookbehind</p>
<pre><code>s/(?<!:)\bBoolean\b/bool/g;
</code></pre>
<p>For #2, I used lookahead.</p>
<pre><code>s/(?<!:)\bBoolean\b(?!")/bool/g</pre>
</code></pre>
<p>This will most likely work for my situation but how about the following improvements?</p>
<p>3) Do not match if in the middle of a string (thanks <a href="https://stackoverflow.com/users/3101/nohat">nohat</a>).<br>
4) Do not match if in a comment. (// or /**/) </p>

<p>What would be the best algorithm for finding a number that occurs only once in a list which has all other numbers occurring exactly twice.</p>
<p>So, in the list of integers (lets take it as an array) each integer repeats exactly twice, except one. To find that one, what is the best algorithm.</p>

<p>Have you guys had any experiences (positive or negative) by placing your source code/solution on a network drive for Visual Studio 2005 or 2008? Please note I am not referring to placing your actual source control system on that drive, but rather your working folder.</p>
<p>Thanks</p>

<p>The compiler usually chokes when an event doesn't appear beside a <code>+=</code> or a <code>-=</code>, so I'm not sure if this is possible.</p>
<p>I want to be able to identify an event by using an Expression tree, so I can create an event watcher for a test. The syntax would look something like this:</p>
<pre><code>using(var foo = new EventWatcher(target, x => x.MyEventToWatch) {
// act here
} // throws on Dispose() if MyEventToWatch hasn't fired
</code></pre>
<p>My questions are twofold:</p>
<ol>
<li>Will the compiler choke? And if so, any suggestions on how to prevent this?</li>
<li>How can I parse the Expression object from the constructor in order to attach to the <code>MyEventToWatch</code> event of <code>target</code>?</li>
</ol>

<p>I have a Flex <code>ComboBox</code> that gets populated by a <code>dataprovider</code> all is well...</p>
<p>I would now like to add a default " -- select a item --" option at the 0 index, how can I do this and still use a <code>dataprovider</code>? I have not seen any examples of such, but I can't imagine this being hard...</p>

<p>I used the jQuery Form plugin for asynchronous form submission. For forms that contain files, it copies the form to a hidden iframe, submits it, and copies back the iframe's contents. The problem is that I can't figure out how to find what HTTP status code was returned by the server. For example, if the server returns 404, the data from the iframe will be copied as normal and treated as a regular response.</p>
<p>I've tried poking around in the iframe objects looking for some sort of <code>status_code</code> attribute, but haven't been able to find anything like that.</p>
<hr>
<p>The <code>$.ajax()</code> function can't be used, because it does not support uploading files. The only way to asynchronously upload files that I know of is using the hidden <code>iframe</code> method.</p>

<p>I want to escape a DOS filename so I can use it with sed. I have a DOS batch file something like this:</p>
<pre><code>set FILENAME=%~f1
sed 's/Some Pattern/%FILENAME%/' inputfile
</code></pre>
<p>(Note: <code>%~f1</code> - expands <code>%1</code> to a Fully qualified path name - <code>C:\utils\MyFile.txt</code>)</p>
<p>I found that the backslashes in <code>%FILENAME%</code> are just escaping the next letter.</p>
<p>How can I double them up so that they are escaped?</p>
<p>(I have cygwin installed so feel free to use any other *nix commands)</p>
<h1>Solution</h1>
<p>Combining Jeremy and Alexandru Nedelcu's suggestions, and using | for the delimiter in the sed command I have</p>
<pre><code>set FILENAME=%~f1
cygpath "s|Some Pattern|%FILENAME%|" >sedcmd.tmp
sed -f sedcmd.tmp inputfile
del /q sedcmd.tmp
</code></pre>

<p>I have always used <code>||</code> (two pipes) in OR expressions, both in C# and PHP. Occasionally I see a single pipe used: <code>|</code>. What is the difference between those two usages? Are there any caveats when using one over the other or are they interchangeable?</p>

<p>When I log into a remote machine using ssh X11 forwarding, Vista pops up a box complaining about a process that died unexpectedly. Once I dismiss the box, everything is fine. So I really don't care if some process died. How do I get Vista to shut up about it?</p>
<hr>
<p>Specifically, the message reads:</p>
<pre><code>sh.exe has stopped working
</code></pre>
<p>So it's not ssh itself that died, but some sub-process.</p>
<p>The problem details textbox reads:</p>

<p>I notice the problem occurs when I use the <strong>-Y</strong> option to enable X11 forwarding in an X terminal under Vista.</p>
<p>The dialog box that pops up doesn't automatically gain focus, so pressing Enter serves no purpose. I have to wait for the box to appear, grab it with the mouse, and dismiss it. Even forcing the error to receive focus would be a step in the right direction.</p>

<p>In the code below I am using a recursive CTE(Common Table Expression) in SQL Server 2005 to try and find the top level parent of a basic hierarchical structure. The rule of this hierarchy is that every CustID has a ParentID and if the CustID has no parent then the ParentID = CustID and it is the highest level.</p>
<pre><code>DECLARE @LookupID int
--Our test value
SET @LookupID = 1
WITH cteLevelOne (ParentID, CustID) AS
(
SELECT a.ParentID, a.CustID
FROM tblCustomer AS a
WHERE a.CustID = @LookupID
UNION ALL
SELECT a.ParentID, a.CustID
FROM tblCustomer AS a
INNER JOIN cteLevelOne AS c ON a.CustID = c.ParentID
WHERE c.CustID <> a.CustomerID
)
</code></pre>
<p>So if tblCustomer looks like this: </p>
<pre><code>ParentID CustID
5 5
1 8
5 4
4 1
</code></pre>
<p>The result I get from the code above is: </p>
<pre><code>ParentID CustID
4 1
5 4
5 5
</code></pre>
<p>What I want is just the last row of that result: </p>
<pre><code>ParentID CustID
5 5
</code></pre>
<p>How do I just return the last record generated in the CTE (which would be highest level CustID)?</p>
<p>Also note that there are multiple unrelated CustID hierarchies in this table so I can't just do a SELECT * FROM tblCustomer WHERE ParentID = CustID. I can't order by ParentID or CustID because the ID number is not related to where it is in the hierarchy.</p>

<p>I'm writing an app using asp.net-mvc deploying to iis6. I'm using forms authentication. Usually when a user tries to access a resource without proper authorization I want them to be redirected to a login page. FormsAuth does this for me easy enough.</p>
<p>Problem: Now I have an action being accessed by a console app. Whats the quickest way to have this action respond w/ status 401 instead of redirecting the request to the login page? </p>
<p>I want the console app to be able to react to this 401 StatusCode instead of it being transparent. I'd also like to keep the default, redirect unauthorized requests to login page behavior.</p>
<p>Note: As a test I added this to my global.asax and it didn't bypass forms auth:</p>
<pre><code>protected void Application_AuthenticateRequest(object sender, EventArgs e)
{
HttpContext.Current.SkipAuthorization = true;
}
</code></pre>
<hr>
<p>@Dale and Andy</p>
<p>I'm using the AuthorizeAttributeFilter provided in MVC preview 4. This is returning an HttpUnauthorizedResult. This result is correctly setting the statusCode to 401. The problem, as i understand it, is that asp.net is intercepting the response (since its taged as a 401) and redirecting to the login page instead of just letting it go through. I want to bypass this interception for certain urls.</p>

<p>I'm working on a database for a small web app at my school using <code>SQL Server 2005</code>.<br>
I see a couple of schools of thought on the issue of <code>varchar</code> vs <code>nvarchar</code>:</p>
<ol>
<li>Use <code>varchar</code> unless you deal with a lot of internationalized data, then use <code>nvarchar</code>.</li>
<li>Just use <code>nvarchar</code> for everything.</li>
</ol>
<p>I'm beginning to see the merits of view 2. I know that nvarchar does take up twice as much space, but that isn't necessarily a huge deal since this is only going to store data for a few hundred students. To me it seems like it would be easiest not to worry about it and just allow everything to use nvarchar. Or is there something I'm missing?</p>

<p>I need to to print natural nos. 1,2,...n such that the parent process prints all odd numbers and the child process prints all even numbers, and all of this needs to be done using POSIX signals. How would I go about accomplishing this?</p>
<p>The output should be:</p>
<p>Parent : 1<br>
Child : 2<br>
Parent : 3<br>
...</p>

<p>I was given a C++ project that was compiled using MS Visual Studio .net 2003 C++ compiler, and a .mak file that was used to compile it. I am able to build it from the command line using nmake project.mak, but the compiler complains that afxres.h was not found. I did a little searching around and the afxres.h is in the Visual Studio directory in an includes file. Where am I supposed to specify to nmake where to look for this header file?</p>

<p>Some code that rounds up the division to demonstrate (C-syntax):</p>
<pre><code>#define SINT64 long long int
#define SINT32 long int
SINT64 divRound(SINT64 dividend, SINT64 divisor)
{
SINT32 quotient1 = dividend / divisor;
SINT32 modResult = dividend % divisor;
SINT32 multResult = modResult * 2;
SINT32 quotient2 = multResult / divisor;
SINT64 result = quotient1 + quotient2;
return ( result );
}
</code></pre>
<p>Now, if this were User-space we probably wouldn't even notice that our compiler is generating code for those operators (e.g. <code>divdi3()</code> for division). Chances are we link with <code>libgcc</code> without even knowing it. The problem is that Kernel-space is different (e.g. no <code>libgcc</code>). What to do?</p>
<p>Crawl Google for a while, notice that pretty much everyone addresses the unsigned variant:</p>
<pre><code>#define UINT64 long long int
#define UINT32 long int
UINT64 divRound(UINT64 dividend, UINT64 divisor)
{
UINT32 quotient1 = dividend / divisor;
UINT32 modResult = dividend % divisor;
UINT32 multResult = modResult * 2;
UINT32 quotient2 = multResult / divisor;
UINT64 result = quotient1 + quotient2;
return ( result );
}
</code></pre>
<p>I know how to fix this one: Override <code>udivdi3()</code> and <code>umoddi3()</code> with <code>do_div()</code> from <em>asm/div64.h</em>. Done right? Wrong. Signed is not the same as unsigned, <code>sdivdi3()</code> does not simply call <code>udivdi3()</code>, they are separate functions for a reason.</p>
<p>Have you solved this problem? Do you know of a library that will help me do this? I'm really stuck so whatever you might see here that I just don't right now would be really helpful.</p>
<p>Thanks,
Chad</p>

<p>I'm currently working on a large implementation of Class::DBI for an existing database structure, and am running into a problem with clearing the cache from Class::DBI. This is a mod_perl implementation, so an instance of a class can be quite old between times that it is accessed.
From the man pages I found two options:</p>
<pre><code>Music::DBI->clear_object_index();
</code></pre>
<p>And:</p>
<pre><code>Music::Artist->purge_object_index_every(2000);
</code></pre>
<p>Now, when I add clear_object_index() to the DESTROY method, it seems to run, but doesn't actually empty the cache. I am able to manually change the database, re-run the request, and it is still the old version.
purge_object_index_every says that it clears the index every n requests. Setting this to "1" or "0", seems to clear the index... sometimes. I'd expect one of those two to work, but for some reason it doesn't do it every time. More like 1 in 5 times.</p>
<p>Any suggestions for clearing this out?</p>

<p>What is the best way to create fluid width/height rounded corners with jQuery?</p>
<hr>
<p>That plugin doesn't keep the height the same. I have a 10px high div that I want to round the corners on, when I use that script it adds about 10px onto whats there.</p>

<p>I'm looking to run Redmine, a Ruby on Rails app, on a VPS windows box. The only thing I can really think of is running a virtual Linux machine and hosting it from there. If that is my only option, am I going to run into problems running a virtual machine inside of a virtual machine?</p>
<p>Also, this will be an internal app, so performance isn't my number once concern.</p>

<p>In the project I am currently working on, we have the need to develop a web chat application, not a very complex chat, just a way to connect two people to talk about a very specific topic, we don't need any kind of authentication for one of the two users, we don't have to support emoticons, avatars, or stuff like that.</p>
<p>Some project members suggested that we could use XMPP through BOSH, I said that is like trying to catch a fish with a boat's net, and proposed a simpler method, like a simple Ajax/MySQL web chat, but we're worried about the performance hit in the server because of the constant polling of many chats open at the same time.</p>
<p>Has anyone done something like this before? What would you recommend? </p>

<p>I have been working with Struts for some time, but for a project I am finishing I was asked to separate Templates (velocity .vm files), configs (struts.xml, persistence.xml) from main WAR file.</p>
<p>I have all in default structure like: </p>
<pre>
application
|-- <i><b>META-INF</b></i> -- Some configs are here
|-- <i><b>WEB-INF</b></i> -- others here
| |-- classes
| | |-- META-INF
| | `-- mypackage
| | `-- class-files
| `-- lib
|-- css
`-- <i><b>tpl</b></i> -- Template dir to be relocated
</pre>
<p>And I apparently can't find documentation about how to setup (probably in struts.xml) where my templates go, and where config files will be.</p>
<p>I think I will have to use configurations on the application server too (I am using Jetty 5.1.14).</p>
<p>So, any lights on how to configure it ? </p>
<p>Thanks</p>
<hr>
<p>Well, the whole thing about changing templates place is to put the templates in a designer accessible area, so any modification needed, the designer can load them to his/her computer, edit, and upload it again. I think this is a common scenario. So, probably I am missing something in my research. Maybe I am focusing in configuring it on the wrong place ... Any thoughts ?</p>

<p>Graphics and audio editing and processing software often contain functions called "High-Pass Filter" and "Low-Pass Filter". Exactly what do these do, and what are the algorithms for implementing them?</p>

<p>Using Terminal.app on OS X 10.5, often you see the commands get garbled when you do a reverse-search with Bash. Is there some kind of termcap or perhaps a bash shopt command that can fix this? It is very annoying. </p>
<p>Steps to reproduce: Open Terminal.app, reverse-search to a longish command. Hit <ctrl>-E once you've found the command. The cursor goes to the end of the line, but the display doesn't update. </p>
<p>I'm guessing this is some kind of problem with the readline library on OS X. It's more of a problem with updating the cursor position after a search than anything else. Basically, ctrl-a and ctrl-e tend to break the search output. </p>
<p><a href="http://involution.com/images/osxterminal.png">os x terminal failure image http://involution.com/images/osxterminal.png</a></p>
<p>In the above, the first part of the command should be displayed, and the cursor should be at the end of the line, but it isn't. You literally can't see what you're editing when this happens. </p>

<p>I'll admit that I don't know the inner workings of the unix operating system, so I was hoping someone could shed some light on this topic.</p>
<p>Why is the Unix file system better than the windows file system?</p>
<p>Would grep work just as well on Windows, or is there something fundamentally different that makes it more powerful on a Unix box?</p>
<p>e.g. I have heard that in a Unix system, the number of files in a given directory will not slow file access, while on Windows direct file access will degrade as the # of files increase in the given folder, true?</p>
<p>Updates:
Brad, no such thing as the <a href="http://en.wikipedia.org/wiki/Unix_File_System" rel="noreferrer">unix file system</a>?</p>

<p>I am ready to start using SVN, but I have NO (as in the money required for free beer) experience with source control. I have installed subversion on my server (that was easy, 'apt-get install subversion') but now I don't know what to do, how to configure it, or how to use it.<br /><br />What suggestions do you have, and where can I find good resources to learn to start using it?<br /><br />
Update:<br />
O.K. So the feedback has been great and I have read through a bit of it but I want to clarify my question by saying that I am looking for more information on how to actually go about setting my up my repositories, clients, server, etc. I know that I could do a quick Google search and find dozens (or more) resources but I'm hoping that someone whom has experience with subversion and a client(I have installed tortoise) could suggest a good reference that will be reliable, and have quality content.</p>
