<p>I have the classical table with expandable and collapsible records that if expanded show several subrecords (as new records in the same parent table, not some child div/child table). I am also using tablesorter and absolutely love it.</p>
<p>The problem is that tablesorter isn't keeping expanded child records next to the parent records. It sorts them as if they were top level. So each time the table gets sorted by a column the child rows end up all over the place and not where I want them.</p>
<p>Does anyone know of a good extension to tablesorter or specific configuration that enables tablesorter to keep child rows grouped together with the parent row even after sorting? Or do I have to give up tablesorter in favor of some other API or start the ugly process of writing my own widget? Should I avoid the css-based approach of hiding individual rows of the table to represent collapse rows?</p>

<p>Is there a command like <code>cat</code> in linux which can return a specified quantity of characters from a file?</p>
<p>e.g., I have a text file like:</p>
<pre><code>Hello world
this is the second line
this is the third line
</code></pre>
<p>And I want something that would return the first 5 characters, which would be "hello".</p>
<p>thanks</p>

<p>I'm pretty sure one would do this using the os.plock(op) function, but I have no idea how. Also, if there's a better way, I'd be grateful to find out. Code snippets are very welcome. </p>

<p>I have a problem perplexing me to no end. When I run the following query against an access database:</p>
<pre><code>SELECT *
FROM PreferredSpacer INNER JOIN SpacerThickness ON PreferredSpacer.SpacerTypeID = SpacerThickness.SpacerTypeID
ORDER BY PreferredSpacer.UnitTypeID DESC
</code></pre>
<p>(UnitTypeID field is a text type)</p>
<p>The results do not come out sorted as a normal person would expect. They are all over the place with respect to the UnitTypeID field (There are entries starting with 'W' between entries starting with 'C' and 'M'). If I remove the join and just try to order the records in the PreferredSpacer table (which contains the UnitTypeID field) I get my expected results, so I must assume the join has something to do with it.</p>
<p>At the same time however, I honestly can't imagine a tool as ubiquitus as access could have such a glaring issue with a fairly basic query. If I am doing something wrong -- however -- I am not able to see what it could be.</p>
<p>Any assistance would be greatly appreciated. Thanks.</p>

<p>I am attempting to pass information from a task created within a workflow to its corresponding task form. Prior to the CreateTask activity, I create an SPWorkflowTaskProperties and fill it with the usual info (title, assigned-to, etc). I also add some elements to the ExtendedProperties property. However, those custom properties never make it into the Task.</p>
<p>I've tried setting the property key to:</p>
<ul>
<li>the Guid of one of my task' content
type's fields;</li>
<li>the internal name of
one of my task' content type's
fields;</li>
<li>an unrelated name (in the
hopes of getting the info into the
task's properties instead of its
fields).</li>
</ul>
<p>Nothing works. The task, once created, contains only the built-in field values I have set. None of values I explicitly added to the extended properties show up.</p>
<p>The (simplified) sequence of my activities is as follows:</p>
<ul>
<li>PrepareTask. This is a custom
activity that contains the
SPWorkflowTaskProperties </li>
<li>CreateTask. The task properties are bound to the one in the PrepareTask activity.</li>
<li>OnTaskCreated. The task properties are bound to the one in the PrepareTask activity.</li>
<li>While (task not complete)
<ul>
<li>OnTaskChanged</li>
</ul></li>
</ul>
<p>I am using WSS 3.0 SP1 and an ASPX (NOT InfoPath) task form.</p>

<p>We have inherited an ant build file but now need to deploy to both 32bit and 64bit systems.</p>
<p>The non-Java bits are done with GNUMakefiles where we just call "uname" to get the info. Is there a similar or even easier way to mimic this with ant?</p>

<p>If I view the HTML generated by one of my Jasper reports in IE7 I see the following: </p>
<pre><code><BR /><BR />
<A name="JR_PAGE_ANCHOR_0_1">
<TABLE style="WIDTH: 1000px" cellSpacing="0" cellPadding="0" bgColor="#ffffff" border="0">
<-- table body omitted -->
</TABLE>
</code></pre>
<p>The two BR tags are added via the JRHtmlExporterParameter.HTML_HEADER parameter. After these tags and before the beginning of the report table that there's an unclosed anchor tag that is generated by Jasper reports. The fact that this tag is not correctly closed is messing up the formatting of my report because IE is hyperlinking the entire report TABLE. I'm not using this anchor tag, so if I could prevent Jasper from generating it, that would solve my problem.</p>
<p>Incidentally, this problem only occurs in IE, in Firefox everything works fine because the anchor tag is properly closed.</p>
<p>Thanks in advance,
Don</p>

<p>I'm trying to construct a query that will include a column indicating whether or not a user has downloaded a document. I have a table called HasDownloaded with the following columns: id, documentID, memberID. Finding out whether a user has downloaded a <em>specific</em> document is easy; but I need to generate a query where the results will look like this:</p>
<pre><code>name id
----------------------
abc NULL
bbb 2
ccc 53
ddd NULL
eee 13
</code></pre>
<p>The ID isn't really important; what I'm interested in is whether the document has been downloaded (is it NULL or not).</p>
<p>Here is my query:</p>
<pre><code>SELECT Documents.name, HasDownloaded.id FROM Documents
LEFT JOIN HasDownloaded ON HasDownloaded.documentID = Documents.id
WHERE HasDownloaded.memberID = @memberID
</code></pre>
<p>The problem is, this will only return values if an entry exists for the specified user in the HasDownloaded table. I'd like to keep this simple and only have entries in HasDownloaded for documents that <em>have</em> been downloaded. So if user 1 has downloaded abc, bbb, and ccc, I still want ddd and eee to show up in the resulting table, just with the id as NULL. But the WHERE clause only gives me values for which entries exists.</p>
<p>I'm not much of a SQL expert - is there an operator that will give me what I want here? Should I be taking a different approach? Or is this impossible?</p>

<p>I'm trying to get some code working that a previous developer has written.
Yep, he now left the company. :-(</p>
<p>I have a JSON RPC call being made from the JS code.
The JS all runs fine and the callback method gets an object back (not an error object).</p>
<p>But the method on the Java class never gets hit.
The smd method does get hit though.</p>
<hr>
<pre><code>public String smd()
{
return SUCCESS; // break point reaches here
}
@SMDMethod
public void updateRowValueForField(String key, String value, String fieldname)
{
// We never get into this method.
}
</code></pre>
<hr>
<pre><code><package name="EntryBarRPC" namespace="/" extends="star-default">
<action name="ebToggleSelection" class="eboggleSelectionAction" method="smd">
<interceptor-ref name="jsonStack">
<param name="enableSMD">true</param>
</interceptor-ref>
<result type="json">
<param name="enableSMD">true</param>
</result>
</action>
</package>
</code></pre>
<hr>
<p>I'm stumped as to why, or what I'm missing.
I've read <a href="http://cwiki.apache.org/S2PLUGINS/json-plugin.html" rel="nofollow noreferrer">JSON plugin page</a> over and over.</p>
<p>I think I just need another set of eyes.</p>
<p>Note: no errors in the Tomcat console, no JS errors.</p>
<p>Anyone got any clues?
Cheers
Jeff Porter</p>

<p>In ActivePerl, "ppm" installs a package from the Internet, "ppm install x.ppd" installs from a ppd file, but most CPAN packages are distributed as <em>.tar.gz</em></p>
<p>How do you supply modules to a machine running ActivePerl that doesn't have an Internet connection? ("make" will probably not be available.)</p>
<p>Update: an Internet connection can be used to download files and transfer them to the machine with a USB key, etc.</p>

<p>I'm looking for an abstract base class or master page solution that will prevent anyone from doing XSRF using both a token and ttl. Can anyone point me in the right direction?</p>
<p>Edit: The ideal solution will leverage the cookie that the default membership provider sends down to the client.</p>

<p><strong>Answer</strong></p>
<pre><code>(date1..date2).size() == 1 // true if two dates are on same calendar day

<p>I have a <a href="http://en.wikipedia.org/wiki/Bluehost" rel="noreferrer">Bluehost</a> account where I can run Python scripts as CGI. I guess it's the simplest CGI, because to run I have to define the following in <code>.htaccess</code>:</p>
<pre><code>Options +ExecCGI
AddType text/html py
AddHandler cgi-script .py
</code></pre>
<p>Now, whenever I look up web programming with Python, I hear a lot about WSGI and how most frameworks use it. But I just don't understand how it all fits together, especially when my web server is given (Apache running at a host's machine) and not something I can really play with (except defining <code>.htaccess</code> commands).</p>
<p>How are <a href="http://en.wikipedia.org/wiki/Web_Server_Gateway_Interface" rel="noreferrer">WSGI</a>, CGI, and the frameworks all connected? What do I need to know, install, and do if I want to run a web framework (say <a href="http://webpy.org/" rel="noreferrer">web.py</a> or <a href="http://en.wikipedia.org/wiki/CherryPy" rel="noreferrer">CherryPy</a>) on my basic CGI configuration? How to install WSGI support?</p>

<p>I'm working on keyboard input for a very basic kernel that I'm developing and I'm completely stuck. I can't seem to find any information online that can show me the information I need to know.</p>
<p>My kernel is running in protected mode right now, so I can't use the real mode keyboard routines without jumping into real mode and back, which I'm trying to avoid. I want to be able to access my keyboard from protected mode. Does anyone know how to do this? The only thing I have found so far is that it involves talking to the controller directly using in/out ports, but beyond that I'm stumped. This is, of course, is not something that comes up very often. Normally, Assembly tutorials assume you're running an operating system underneath.</p>
<p>I'm very new to the x86 assembly, so I'm just looking for some good resources for working with the standard hardware from protected mode. I'm compiling the Assembly source code with NASM and linking it to the C source code compiled with DJGPP. Any suggestions?</p>

<p>I have been reading carefully through the mediawiki documentation but I have not been able to find out how to create new groups. </p>
<p>When I look at Special:Userrights, I see only 3 groups :
Bots, Sysops, Bureaycrats</p>
<p>I would like to create my own custom groups, so I can use some extensions like the <a href="http://www.mediawiki.org/wiki/Extension:Group_Based_Access_Control" rel="noreferrer">http://www.mediawiki.org/wiki/Extension:Group_Based_Access_Control</a>.</p>
<p>Can someone tell me how it's done, or point me to some documentation?</p>

<p>I need to run a Linux CLI command and get its stdout output from C.</p>
<p>I can use pipe() to create a pipe, then fork/exec, redirecting child's stdout descriptor into the pipe before calling exec(), and reading from the pipe in parent. Plus I'll need to wait on the child.</p>
<p>Is there a simple call to do fork + redirect + exec + wait, like system() does fork + exec + wait, only system() doesn't do the redirect.</p>
<p>There's popen(), which does fork + redirect + exec, but doesn't do wait, so I can't get exit status.</p>

<p>I'm trying to use stl algorithm for_each without proliferating templates throughout my code. std::for_each wants to instantiate MyFunctor class by value, but it can't since its abstract. I've created a functor adapter class which passes a pointer around and then derefernces it when appropriate.</p>
<p>My Question: </p>
<p>Does the STL or Boost already have such an adapter class? I don't want to have to reinvent the wheel!</p>
<pre><code> struct MyFunctor {
virtual ~MyFunctor() {}
virtual void operator()(int a) = 0;
}
namespace {
template<typename FunctorType, typename OperandType> struct
FunctorAdapter
{
FunctorAdapter(FunctorType* functor) : mFunctor(functor) {}
void operator()(OperandType& subject)
{
(*mFunctor)(subject);
}
FunctorType* mFunctor;
}; }
void applyToAll(MyFunctor &f) {
FunctorHelper<MyFunctor, int> tmp(&f);
std::for_each(myvector.begin(), myvector.end(), tmp); }
</code></pre>
<p>Cheers,</p>

<p>I want to create a WCF-service hosted in IIS6 and disable anonymous authentication in IIS. And don't use SSL.</p>
<p>So only way I have is to use basicHttpBinging with <code>TransportCredentialOnly</code>, itsn't it?</p>
<p>I create a virtual directory, set Windows Integrated Auth and uncheck "Enable Anonymous Access".</p>
<p>Here's my web.config:</p>
<pre><code><system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="MyBinding">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<services>
<service name="Samples.ServiceFacadeService" behaviorConfiguration="ServiceFacadeServiceBehavior">
<endpoint address="" binding="basicHttpBinding" bindingName="MyBinding"
contract="Samples.IServiceFacadeService">
</endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceFacadeServiceBehavior">
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</code></pre>
<p>You can see that I even haven't included MEX-enpoint for metadata exchange. Just one endpoint and one binding for it with TransportCredentialOnly security.</p>
<p>But when I tries to start service (invoking a method throught client proxy) I got such exception in the EventLog:</p>
<blockquote>
<p>Exception:
System.ServiceModel.ServiceActivationException:
The service
'/wcftest/ServiceFacadeService.svc'
cannot be activated due to an
exception during compilation. The
exception message is: Security
settings for this service require
'Anonymous' Authentication but it is
not enabled for the IIS application
that hosts this service.. --->
System.NotSupportedException: Security
settings for this service require
'Anonymous' Authentication but it is
not enabled for the IIS application
that hosts this service.</p>
</blockquote>
<p>I have no idea why my service require Anonymous auth? Why?</p>

<p><a href="http://en.wikipedia.org/wiki/Literate_programming" rel="noreferrer">Literate programming</a> is a way of developing software where documentation comes first, then the coding. One writes the documentation of a code snippet, and then writes the implementation of the snippet. The visual appearance of the software source code would be a plain document like word, with code paragraphs in it. </p>
<p>I am trying to convert the dev shop I work to use only literate programming, as it brings great advantages to code readability and maintenance. However, due to the lack of tools the LP usage is limited in the company. For example, the ideal way to program literate is to write a paragraph using word markup, and then insert a subparagraph with the implementation. But i cannot seem to find any good tools for VS200x to perform LP with. </p>
<p>Ideally, such a tool would look just like Word 2007, but integrated into the IDE. When the coder sets the cursor on a code paragraph, it would have all the functionality provided just like we have now in our IDE. </p>
<p>What are good tools for LP, with .NET and VS200x in particular?</p>

<p>Is it possible to to change a <code><span></code> tag (or <code><div></code>) to preformat its contents like a <code><pre></code> tag would using only CSS?</p>

<p>Recently I have been studying recursion; how to write it, analyze it, etc. I have thought for a while that recurrence and recursion were the same thing, but some problems on recent homework assignments and quizzes have me thinking there are slight differences, that 'recurrence' is the way to describe a recursive program or function.</p>
<p>This has all been very Greek to me until recently, when I realized that there is something called the 'master theorem' used to write the 'recurrence' for problems or programs. I've been reading through the wikipedia page, but, as usual, things are worded in such a way that I don't really understand what it's talking about. I learn much better with examples.</p>
<p>So, a few questions:
Lets say you are given this recurrence:</p>
<blockquote>
<p>r(n) = 2*r(n-2) + r(n-1);<br>
r(1) = r(2)
= 1</p>
</blockquote>
<p>Is this, in fact, in the form of the master theorem? If so, in words, what is it saying? If you were to be trying to write a small program or a tree of recursion based on this recurrence, what would that look like? Should I just try substituting numbers in, seeing a pattern, then writing pseudocode that could recursively create that pattern, or, since this may be in the form of the master theorem, is there a more straightforward, mathematical approach?</p>
<p>Now, lets say you were asked to find the recurrence, T(n), for the number of additions performed by the program created from the previous recurrence. I can see that the base case would probably be T(1) = T(2) = 0, but I'm not sure where to go from there.</p>
<p>Basically, I am asking how to go from a given recurrence to code, and the opposite. Since this looks like the master theorem, I'm wondering if there is a straightforward and mathematical way of going about it.</p>
<p>EDIT: Okay, I've looked through some of my past assignments to find another example of where I'm asked, 'to find the recurrence', which is the part of this question I'm having the post trouble with.</p>
<blockquote>
<p>Recurrence that describes in the best
way the number of addition operations
in the following program fragment
(when called with l == 1 and r == n)</p>
</blockquote>
<pre><code>int example(A, int l, int r) {
if (l == r)
return 2;
return (A[l] + example(A, l+1, r);
}
</code></pre>

<p>I'm looking for a way to transform a genuine string into it's hexadecimal value in SQL. I'm looking something that is Informix-friendly but I would obviously prefer something database-neutral </p>
<p>Here is the select I am using now:</p>
<pre><code>SELECT SomeStringColumn from SomeTable
</code></pre>
<p>Here is the select I would like to use:
SELECT hex( SomeStringColumn ) from SomeTable</p>
<p>Unfortunately nothing is that simple... Informix gives me that message:
<em>Character to numeric conversion error</em></p>
<p>Any idea?</p>

<p>I have inherited a django+fastcgi application which needs to be modified to perform a lengthy computation (up to half an hour or more). What I want to do is run the computation in the background and return a "your job has been started" -type response. While the process is running, further hits to the url should return "your job is still running" until the job finishes at which point the results of the job should be returned. Any subsequent hit on the url should return the cached result. </p>
<p>I'm an utter novice at django and haven't done any significant web work in a decade so I don't know if there's a built-in way to do what I want. I've tried starting the process via subprocess.Popen(), and that works fine except for the fact it leaves a defunct entry in the process table. I need a clean solution that can remove temporary files and any traces of the process once it has finished.</p>
<p>I've also experimented with fork() and threads and have yet to come up with a viable solution. Is there a canonical solution to what seems to me to be a pretty common use case? FWIW this will only be used on an internal server with very low traffic.</p>

<p>I'm using JQuery's jquery.corner.js to create rounded corners on some td tags, and they look fine in IE EXCEPT </p>
<ol>
<li>if you open a new tab and then come back to the page</li>
<li>if you go to another tab, click a link, then come back to the page</li>
<li>if you hover over a javascript-executing div / menu (I think).</li>
</ol>
<p>The rounded corners are replaced with horizontal lines, and text within the td tag is pushed down. Once the page is refreshed, however, the rendering is back to normal. In all cases it works perfectly in Firefox.</p>
<p>Any ideas?</p>
<p>For reference, the Javascript code I'm using is as follows (it's a MOSS 2007 page):</p>
<pre><code>$(document).ready(function(){
$("table.ms-navheader td").corner("top");
});
</code></pre>
<p>Here's a sample HTML page that displays the problem perfectly:</p>
<pre><code><html>
<head>
<script type="text/javascript" src="jquery-1.2.6.js"></script>
<script type="text/javascript" src="jquery.corner.js"></script>
<script type="text/javascript">
<!--
$(document).ready(function()
{
$("div").corner("top");
$("td").corner();
});
//-->
</script>
</head>
<body>
<table>
<tr>
<td style="background-color: blue">
TD that will be messed up.
</td>
</tr>
</table>
<div style="background-color: green">
divs don't get messed up.
</div>
</body>
</html>
</code></pre>
<p>In the above code, the TD will be messed up once you open up a new tab, but not the div. I don't have much control over the HTML emitted by MOSS, otherwise I might have bitten the bullet and used DIVs here instead of a table.</p>

I've downloaded the production directory to my windows machine (running InstantRails 2), I created the databases as required in the <code>database.yml</code> and I tried to run the <code>rake:db:migrate --trace</code> but I'm receiving the following error message:</p>
<pre><code>(in D:/projects/broke2)
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate
rake aborted!

<p>I got a little problem I can't figure out. I have a server side MarshalByRefObject that I'm trying to wrap a transparent proxy around on the client side. Here's the setup:</p>
<pre><code>public class ClientProgram {
public static void Main( string[] args ) {
ITest test = (ITest)Activator.GetObject( typeof( ITest ), "http://127.0.0.1:8765/Test.rem" );
test = (ITest)new MyProxy( test ).GetTransparentProxy();
test.Foo();
}
}
public class MyProxy : RealProxy {
private MarshalByRefObject _object;
public MyProxy( ITest pInstance )
: base( pInstance.GetType() ) {
_object = (MarshalByRefObject)pInstance;
}
public override IMessage Invoke( IMessage msg ) {
return RemotingServices.ExecuteMessage( _object, (IMethodCallMessage)msg );
}
}
</code></pre>
<p>The problem is that the call to RemotingServices.ExecuteMethod, an exception is thrown with the message "ExecuteMessage can be called only from the native context of the object.". Can anyone point out how to get this to work correctly? I need to inject some code before and after the method calls on remote objects. Cheers!</p>

<p>I'm in the process of refactoring a project. I've got an entire subfolder which is known to be broken. Is there any declarative way to exclude that folder from the compile temporarily while I test the refactoring thus far?</p>
<p>I realize I could delete the folder, but I'd like to do this through configuration if possible.</p>

<p>I'm writing a mobile content adaptation plugin for a bespoke CMS in PHP. The CMS contains <code><img/></code> links to images with absolute URLs which are all 400 pixels wide and vary in height.</p>
<p>I'd like to parse the HTML (which is stored in MySQL) and re-scale each image to a new width - this will vary according to the device. I'd also like to cache the images to prevent needlessly resizing them on-the-fly every time the page is loaded</p>
<p>What's the best way for me to achieve this in PHP using either ImageMagick or GD? </p>

<p>I want to find a linux command that can return a part of the string. In most programming languages, it's the <code>substr()</code> function. Does bash have any command that can be used for this purpose. I want to be able to do something like this...
<code>substr "abcdefg" 2 3</code> - prints <code>cde</code>.</p>

<p>Working through some programming interview challenges I found online, I had to write an algorithm to reverse a const char * and return a pointer to a new char *. I think I have it, but to make it work properly I had to do some wonky stuff - basically having to account for the null-terminating character myself. Somehow I feel this is wrong, but I'm stumped, and I was wondering if someone could help me out:</p>
<pre><code>char * reverse(const char * str)
{
int length = strlen(str);
char * reversed_string = new char[length+1];
for(int i = 0; i < length; ++i)
{
reversed_string[i] = str[(length-1) - i];
}
//need to null terminate the string
reversed_string[length] = '\0';
return reversed_string;
}
int main(int argc, char * argv[])
{
char * rev_str = reverse("Testing");
cout << "Your string reversed is this: " << rev_str << endl;
delete rev_str;
rev_str = 0;
return 0;
}
</code></pre>

<p>Is contract to interface as object is to class?</p>
<p>What is the need to differentiate identical things like this, from the code to the executing code? I sort of get the idea behind naming a class a class and the instantiated executing class an object, but overall, is that the only reason for these semi-redundant terms?</p>

<p>during beta testing we discovered connection pooling error messages . Therefore I have been going through the code and closing down the SqlDataReader objects wherever they have been left unclosed. What I need to know is how to close a datareader (or if there is a need at all to close) that is specified in the SelectStatement attribute of the SqlDataSource or ObjectDataSource tags. Could there be connection leak if they are not handled?</p>
<p>Thanks in advance !</p>

</blockquote>
<p>Using SVN and/or Tortoise SVN (or any other SVN tool, really), is it possible to view the history for a specific line of a file?</p>
<p>Recently I've had several occurrences of coming across a line in a file and wanting to find the log entry associated with its creation (either to determine how old the line of code was, or to get a larger context for why it was added).</p>
<p>Right now I'm doing this by hand. I can display the log for the file, go back a ways, and see if the line in question is present. If it is, I go back further. If it isn't, I go look at a more recent revision. Repeat until the revision where the change was made is found.</p>
<p>Needless to say, this process is awkward at best, especially for particularly old files. Does anyone know of an automated method of accomplishing this?</p>

<p>I'm working with a client that needs to generate millions of the alphanumeric codes used in magazine scratch-off cards, bottlecap prizes, and so on. They have to be short enough to print on a cap, they want to make sure that ambiguous characters like 1 and I, 0 and O, etc. are not included, and they have to be explicitly stored for future use -- we can't just have an algorithm that determines 'validity' when someone tries to redeem one. Finally, they want to make sure that the codes are randomly distributed inside of a large "code space" so that people can't just guess additional codes by walking through the alphabet.</p>
<p>Are there any pointers towards reasonably efficient algorithms for generating these kinds of code sets? I've scratched a few out on the back of an envelope, but this problem smells like a trap for the unwary.</p>

<p>If anyone has experience using Oracle text (<code>CTXSYS.CONTEXT</code>), I'm wondering how to handle user input when the user wants to search for names that may contain an apostrophe.</p>
<p>Escaping the ' seems to work in some cases, but not for 's at the end of the word - s is in the list of stop words, and so seems to get removed.</p>
<p>We currently change simple query text (i.e. anything that's just letters) to <code>%text%</code>, for example: </p>
<pre><code>contains(field, :text) > 0
</code></pre>
<p>A search for <strong>O'Neil</strong> works, but <strong>Joe's</strong> doesn't.</p>
<p>Has anyone using Oracle Text dealt with this issue?</p>

<p>What I'm looking for is a basic equivalent of JavaScript's <code>Array::join()</code> whereby you pass in a separator character and uses that in its return string of all the subscripts. I could certainly write my own function using a <code>StringBuilder</code> or whatnot, but there <em>must</em> be something built into the .NET BCL.</p>
<p>EDIT: Array of <em>anything</em>, not necessarily <code>string</code> or <code>char</code>. I'd prefer the method to simply call <code>ToString()</code> on each subscript <code>object</code>. <code>String.Join()</code> is great except that you pass it an array of strings.</p>

<p>I remember working on a project with a group of developers and they always wanted static
html text to be inside of an out tag (<code><c:out value="words" /></code>). I don't remember why
this was the case.</p>
<p>Is this really a best practice when building jsp pages? What are the
advantages/disadvantages of such an approach?</p>

<p>I've been searching around and haven't found any reference to tools that can create Safari's webarchive format.</p>
<p>Does anyone have pointers to code for creating this format, or at least a format reference documentation?</p>
<p>Ideally I'd like to build a tool that takes a directory and splits out a webarchive, for loading into a iPhone.</p>

<p>I have a python script that is a http-server: <a href="http://paste2.org/p/89701" rel="nofollow noreferrer">http://paste2.org/p/89701</a>, when benchmarking it against ApacheBench (ab) with a concurrency level (-c switch) that is lower then or equal to the value i specified in the socket.listen()-call in the sourcecode everything works fine, but as soon as put the concurrency level in apache bench above the value in the socket.listen()-call performance drops through the floor, some example:</p>
<ul>
<li>socket.listen(<strong>10</strong>) and ab -n 50 -c <strong>10</strong> <a href="http://localhost/" rel="nofollow noreferrer">http://localhost/</a> = <strong>1200req/s</strong></li>
<li>socket.listen(<strong>10</strong>) and ab -n 50 -c <strong>11</strong> <a href="http://localhost/" rel="nofollow noreferrer">http://localhost/</a> = <strong>40req/s</strong></li>
<li>socket.listen(<strong>100</strong>) and ab -n 5000 -c <strong>100</strong> <a href="http://localhost/" rel="nofollow noreferrer">http://localhost/</a> = <strong>1000req/s</strong></li>
<li>socket.listen(<strong>100</strong>) and ab -n 5000 -c <strong>101</strong> <a href="http://localhost/" rel="nofollow noreferrer">http://localhost/</a> = <strong>32req/s</strong></li>
</ul>
<p>Nothing changes in the code between the two calls, I can’t figure out what is wrong - been at this problem for one day now. Also note that: The multiplexing version of the same code (I wrote to compare to the threaded version) works FINE no matter what socket.listen() is set to or what the concurrency (-c switch) in apache is set to.</p>
<p><em>I've spent a day on IRC/python docs, posted on comp.lang.python and on my blog - I can't find ANYONE that even has an idea what could be wrong. Help me!</em></p>

<p>I have a table of data, and I allow people to add meta data to that table.</p>
<p>I give them an interface that allows them to treat it as though they're adding extra columns to the table their data is stored in, but I'm actually storing the data in another table.</p>
<pre><code>Data Table
DataID
Data
Meta Table
DataID
MetaName
MetaData
</code></pre>
<p>So if they wanted a table that stored the data, the date, and a name, then I'd have the data in the data table, and the word "Date" in metaname, and the date in MetaData, and another row in the meta table with "Name" in metaname and the name in metadata. </p>
<p>I now need a query that takes the information from these tables and presents it as though coming from a single table with the two additional columns "Data" and "Name" so to the customer it would look like there's a single table with their custom columns:</p>
<pre><code>MyTable
Data
Date
Name
</code></pre>
<p>Or, in other words, how do I go from here:</p>
<pre><code>Data Table
DataID Data
1 Testing!
2 Hello, World!
Meta Table
DataID MetaName MetaData
1 Date 20081020
1 Name adavis
2 Date 20081019
2 Name mdavis
</code></pre>
<p>To here:</p>
<pre><code>MyTable
Data Date Name
Testing! 20081020 adavis
Hello, World! 20081019 mdavis
</code></pre>
<p>Years ago when I did this in MySQL using PHP, I did two queries, the first to get the extra meta data, the second to join them all together. I'm hoping that modern databases have alternate methods of dealing with this.</p>
<p>Related to option 3 of <a href="https://stackoverflow.com/questions/218848/design-decision-dynamically-adding-data-question#218872">this question</a>.</p>

<p>I was asked for a comprehensive breakdown on space used within a specific database.
I know I can use <em>sys.dm_db_partition_stats</em> in SQL Server 2005 to figure out how much space each <em>table</em> in a database is using, but is there any way to determine the individual and total size of the <em>stored procedures</em> in a database? (Short of opening each one and counting the characters, of course.)</p>
<p>Total space used by stored procs is not likely to be significant (compared to actual <em>data</em>), but with hundreds of them, it could add up.</p>

<p>What is the best way to localize a collection (IEnumerable)?
From the BL I retrieve a collection of entities which still need to localized, I figured I write a method which extends the IEnumerable and returns the localized list. </p>
<p>How can i get the code underneath working? Any ideas? Maybe better options? </p>
<pre><code>public static IEnumerable Localize(this IEnumerable items, CultureInfo cultureInfo)
{
foreach(string item in items)
{
/*Error underneath, cannot assign to item*/
item = ResourceHelper.GetString(item, cultureInfo);
}
return (items);
}
</code></pre>

<p>I'm wondering what the best way is to have a "if all else fails catch it".</p>
<p>I mean, you're handling as much exceptions as possible in your application,
but still there are bound to be bugs, so I need to have something that
catches all unhandled exceptions so I can collect information and store
them in a database or submit them to a web service.</p>
<p>Does the AppDomain.CurrentDomain.UnhandledException event capture everything?
Even if the application is multithreaded?</p>
<p>Side note: Windows Vista exposes native API functions that allow any application
to recover itself after a crash... can't think of the name now... but I'd rather not
use it, as many of our users are still using Windows XP.</p>

<p>(C#)</p>
<p>A side note: would putting the string into hex format shrink it the most w/o getting into hardcore shrinking algo's?</p>

<p>I used to have a custom preferences class for my applications. For my next hobby project i wanted to switch to the Preferences API. But the put and get functions require a default value and i do not want to spread default values all over the source files. Even though my project is small i can not imagine changing default values all over the source code. How do you guys use the api? I am thinking of wrapping the preferences api in another class but then what is the point of using the API because it only takes away the burden of saving the file to disk, which isn't that hard using serialization? Am i missing the point?</p>

<p>I'm looking for best practices to integrate log4net to SharePoint for web request, feature activation and all timer stuff. </p>
<p>I have several subprojects in my farm, and I would like to have only one Log4Net.config file.</p>
<p><strong>[Edit]</strong><br>
Not only I need to configure log4net for the web application, which is easy to do (I use global.asax, and a log4net.config file, so I can modify log settings withtout reloading the webapp), but I also need to log asynchronous events:</p>
<ul>
<li>Event Handler (like ItemAdded)</li>
<li>Timer Jobs</li>
<li>...</li>
</ul>

<p>SQL databases seem to be the cornerstone of most software. However, it seems optimized for textual data. In fact when doing any queries involving numerical data, integers specifically, it seems inefficient that the numbers are getting converted to text and then back to native formats both ways between the application and the database. This same inefficiency seems to apply to BLOB data as well. My understanding is that even with something like Linq to SQL, this two way conversion is occuring in the background.</p>
<p>Are there general ways to bypass this overhead with SQL? Are there certain database management systems that handle this more efficiently than others (ie, with non-standard extensions/API's)?</p>
<p>Clarification. In the following select statement, the list of numbers after IN could be more easily passed as a raw array of int, but there seems to be no way of achieving that optimization level.</p>
<pre><code>SELECT foo FROM bar WHERE baz IN (23, 34, 45, 9854004, ...)
</code></pre>

<p>In Visual Studio, I often use objects only for RAII purposes. For example:</p>
<pre><code>ScopeGuard close_guard = MakeGuard( &close_file, file );
</code></pre>
<p>The whole purpose of <em>close_guard</em> is to make sure that the file will be close on function exit, it is not used anywhere else. However, Visual Studio gives me a warning that a "<em>local variable is initialized but not referenced</em>". I want to turn this warning off for this specific case.</p>
<p>How do you deal with this kind of situation? Visual Studio thinks that this object is useless, but this is wrong since it has a non-trivial destructor.</p>
<p>I wouldn't want to use a <em>#pragma warning</em> directive for this since it would turn off this warning even for legitimate reasons.</p>

<p>I wanna get the Timedate value from another page using request.querystring and then use it an query to compare and pull up the matching datas. The function for the query in linq is:</p>
<pre><code> protected void User_Querytime()
{
DataClasses2DataContext dc1 = new DataClasses2DataContext();
String Data = Request.QueryString["TimeOfMessage"];
var query7 = from u in dc1.syncback_logs
where u.TimeOfMessage = Data
orderby u.TimeOfMessage descending
select u;
GridView1.DataSource = query7;
GridView1.DataBind();
}
</code></pre>
<p>Here the "Request.QueryString["TimeOfMessage"]" which i get is DateTime (ex:8/25/2008 9:07:19 AM). I wanted to compare it against the "u.TimeOfMessage" in database and pull up the matching records. </p>
<p>When I use todatetime function to convert from string to datetime ,the value returned is bool and hence not able to compare it against the "Timeofmessage" which is datetime format in database. Can anyone help me in this?</p>

<p>I can't seems to change the default color of the required field validator. In the source it is:</p>
<pre><code><span class="required">*</span>
<asp:RequiredFieldValidator ID="valReq_txtTracks" runat="server"
ControlToValidate="txtTracks"
Display="Dynamic" />
</code></pre>
<p>Here's what I have in my .skin file:</p>
<pre><code><asp:RequiredFieldValidator runat="server"
CssClass="error-text"
ErrorMessage="required" />
</code></pre>
<p>In the rendered source I see:</p>
<pre><code><span class="required">*</span>
<span id="ctl00_ctl00_cphContent_cphContent_valReq_txtTracks" class="error-text" style="color:Red;display:none;">required</span>
</code></pre>
<p>Notice the "style=color:Red;". That needs to go. I can't override it with a css-class because it's inline CSS. What should I do?</p>

<p>I have a large (700kb) Flex .swf file representing the main file of a site. </p>
<p>For performance testing I wanted to try and move it off to Amazon S3 hosting (which i have already done with certain videos and large files). </p>
<p>I went ahead and did that, and updated the html page to reference the remote .swf.</p>
<p>It turns out that Flash will load any resources relative to the .swf file accessing the resource - no matter what the root of the html page is. So my resources are now being loaded from the remote site (where they don't exist).</p>
<p>There are two obvious things I could do :
* copy all my resources remotely (not ready for this since i'm just testing now)
* add in some layer of abstraction to every URL that the .swf accesses to derive a new path.</p>
<p>I really want to flick a switch and say 'load everything relative to [original server]'.</p>
<p>Does such a thing exist or am I stuck loading everythin from the remote machine unless I fully qualify every path?</p>
<p>i want to avoid anything 'hacky' like : subclass Image and hack the path there</p>

<h2>I'm looking to add some lookup lists in the database, but I want them to be easy localizable (SQL 2005, ADO.NET)</h2>
<p>This would include:</p>
<ul>
<li>Easy Management of multiple languages at the same time</li>
<li>Easy Retrieval of values from the database</li>
<li>Fallback language (in case the selected language is missing)</li>
</ul>
<p>I was thinking about having a table that would store the multi-language lookup-list (using for different languages the same id) and use a function that would return the value of the look-up list - by receiving the ID and the Language.</p>
<p>One of the pitfalls would be that i have to manually add a language parameter to every query that uses the lookup list.</p>
<p>I'm looking into a solution that would let me send the parameter as a "session/global variable", or that would send the parameter automatically with the sql query, and the function to retrieve it by itself (either to attach the parameter automatically, either to be able to read the parameter).</p>
<p>The solution can look something like this, but I don't mind if it is different, as long as it doesn't give the parameter explicitly to the Query (pseudocode):</p>
<blockquote>
<pre><code>1. Send the language using "the method"
2. Execute Query
3. Get the localized results
</code></pre>
</blockquote>
<p>Clarification:</p>
<ol>
<li><p>Normally the query would look like this (remember using the lookup function):</p>
<p><code>SELECT .., GetLookupList1(lookup_ID, language), .. FROM TABLE</code></p></li>
</ol>
<p>The GetLookupList1 is a user defined function that retrieves the lookup value for a lookup table. By using this function, the SQL Code is easier to read and maintain.</p>
<p>The body of the function would be something like:</p>
<pre><code>SELECT @result = LookupValue FROM LookupTable1 WHERE ID=@Lookup_ID and Language=@lang
RETURN @result
</code></pre>
<ol start="2">
<li><p>What I want is to be able to remove the language parameter from the function to some kind of a static variable, available only for the current connection/statement/command, so the query would look like</p>
<p><code>SELECT .., GetLookupList1(lookup_ID), .. FROM TABLE</code></p></li>
</ol>

<p>I've seen some very good questions on Stack Overflow concerning delegates, events, and the .NET implementation of these two features. One question in particular, "<a href="https://stackoverflow.com/questions/213638/how-do-c-events-work-behind-the-scenes#213651">How do C# Events work behind the scenes?</a>", produced a great answer that explains some subtle points very well. </p>
<p>The answer to the above question makes this point:</p>
<blockquote>
<p>When you declare a field-like event
... the compiler generates the methods
and a private field (of the same type
as the delegate). Within the class,
when you refer to ElementAddedEvent
you're referring to the field. Outside
the class, you're referring to the
field</p>
</blockquote>
<p>An MSDN article linked from the same question ("<a href="http://msdn.microsoft.com/en-us/library/aa664455.aspx" rel="nofollow noreferrer">Field-like events</a>") adds:</p>
<blockquote>
<p>The notion of raising an event is
precisely equivalent to invoking the
delegate represented by the event —
thus, there are no special language
constructs for raising events.</p>
</blockquote>
<p>Wanting to examine further, I built a test project in order to view the IL that an event and a delegate are compiled to:</p>
<pre><code>public class TestClass
{
public EventHandler handler;
public event EventHandler FooEvent;
public TestClass()
{ }
}
</code></pre>
<p>I expected the delegate field <code>handler</code> and the event <code>FooEvent</code> to compile to roughly the same IL code, with some additional methods to wrap access to the compiler-generated <code>FooEvent</code> field. But the IL generated wasn't quite what I expected: </p>
<pre><code>.class public auto ansi beforefieldinit TestClass
extends [mscorlib]System.Object
{
.event [mscorlib]System.EventHandler FooEvent
{
.addon instance void TestClass::add_FooEvent(class [mscorlib]System.EventHandler)
.removeon instance void TestClass::remove_FooEvent(class [mscorlib]System.EventHandler)
}
.method public hidebysig specialname rtspecialname instance void .ctor() cil managed
{
// Constructor IL hidden
}
.field private class [mscorlib]System.EventHandler FooEvent
.field public class [mscorlib]System.EventHandler handler
}
</code></pre>
<p>Since events are nothing more than delegates with compiler-generated <code>add</code> and <code>remove</code> methods, I didn't expect to see events treated as anything more than that in IL. But the add and remove methods are defined in a section that begins <code>.event</code>, not <code>.method</code> as normal methods are. </p>
<p>My ultimate questions are: if events are implemented simply as delegates with accessor methods, what is the point of having a <code>.event</code> IL section? Couldn't they be implemented in IL without this by using <code>.method</code> sections? Is <code>.event</code> equivalent to <code>.method</code>? </p>

<p>I am trying to fill a form in a php application from a C# client (Outlook addin). I used Fiddler to see the original request from within the php application and the form is transmitted as a multipart/form. Unfortunately .Net does not come with native support for this type of forms (WebClient has only a method for uploading a file).
Does anybody know a library or has some code to achieve this? I want to post different values and additionally (but only sometimes) a file.</p>
<p>Thanks for your help,
Sebastian</p>

<p>I'm collecting metadata using the sys.* views, and according to the documentation, the sys.identity_columns view will return the seed and increment values like so.</p>
<pre><code>CREATE TABLE ident_test (
test_id int IDENTITY(1000,10),
other int
)
SELECT name, seed_value, increment_value
FROM sys.identity_columns
WHERE object_id = OBJECT_ID( 'ident_test' )
</code></pre>
<p>However, the above query just returns one column. Is it just me?</p>
<p>(Note: I've had to change this question somewhat from its earlier version.)</p>

<p>I want a method of the class: "<code>One</code>" ("<code>AccessibleWithinSameNamespace</code>") to be accessible by the class: "<code>Two</code>", without having "<code>Two</code>" extending "<code>One</code>".</p>
<p>Both classes are in the same namespace, so I'm thinking that maybe there's an access-modifier that emulates the "<em>protected</em>" modifyer, but for namespaces.</p>
<p>Some code:</p>
<pre><code>namespace Test
{
class One
{
public void AccessibleToAll()
{
}
protected void AccessibleWithinSameNamespace()
{
// I am not public
// I can be accessed from other classes
// within the same namespace of my class
}
}
}
namespace Test
{
class Two
{
public Two()
{
One one = new One();
// I am able to access this method because my class
// is in the same namespace as the class: "One"
one.AccessibleWithinSameNamespace();
}
}
}
</code></pre>

<p>I am working on a simple notification service that will be used to deliver messages to the users surfing a website. The notifications do not have to be sent in real time but it might be a better user experience if they happened more frequently than say every 5 minutes. The data being sent to and from the client is not very large and it is a straight forward database query to retrieve the data.</p>
<p>In reading other conversations on the topic it would appear that an AJAX push can result in higher server loads. Since I can tolerate longer server delays is it worth while to have the server push notifications or to simply poll.</p>
<p>It is not much harder to implement the push scenario and so I thought I would see what the opinion was here.</p>
<p>Thanks for your help.</p>
<p>EDIT:
I have looked into a simple AJAX Push and implemented a simple demo based on this <a href="http://uwmike.com/articles/2008/01/22/browser-data-push/#more-384" rel="nofollow noreferrer">article</a> by Mike Purvis.
The client load is fairly low at around 5k for the initial version and expected to stay that way for quite some time.</p>
<hr>
<p>Thank you everyone for your responses. I have decided to go with the polling solution but to wrap it all within a utility library so that if they want to change it later it is easier.</p>

<p>I have a WordPress site (2.6.2) in which I have set the Home page to a static page instead of the normal posts page. The ID of this page is 2, so in the WordPress template I have changed the <code>wp_list_pages</code> to look like this:</p>
<pre><code><?php wp_list_pages('exclude=2&title_li=&depth=1' ); ?>
</code></pre>
<p>this works fine, but now the Home page doesn't get "lit up" when it's selected (because in fact it's page_id 2 that is selected, and it doesn't show in the menu). Is there any easy way around this?</p>
<p>If not, in broad outlines, what's the hard way around this? Make my own version of the <code>wp_list_pages</code> function?</p>
<p>Thanks!</p>

<p>Is there a preference or behavior difference between using:</p>
<pre><code>if(obj.getClass().isArray()) {}

<p>and</p>
<pre><code>if(obj instanceof Object[]) {}

<p>If I have a property that I want to let inheritors write to, but keep readonly externally, what is the preferred way to implement this? I usually go with something like this:</p>
<pre><code>private object m_myProp;
public object MyProp
{
get { return m_myProp; }
}
protected void SetMyProp(object value)
{
m_myProp = value;
}
</code></pre>
<p>Is there a better way?</p>

<p>I've often used pointers to const objects, like so...</p>
<pre><code>const int *p;
</code></pre>
<p>That simply means that you can't change the integer that <code>p</code> is pointing at through <code>p</code>. But I've also seen reference to const pointers, declared like this...</p>
<pre><code>int* const p;
</code></pre>
<p>As I understand it, that means that the pointer variable <em>itself</em> is constant -- you can change the integer it points at all day long, but you can't make it point at something else.</p>
<p>What possible use would that have?</p>

<p>Ok, so I know that global variables are considered bad, and the singleton pattern is overused. And I have read in many places that a class should do only one task and contain only those variables that allow it to accomplish that one task. However, while working on my latest project, I actually thought about these rules before writing any code and have noticed that I tend to break them at the very beginning of the program. </p>
<p>I'm currently working on an MFC dialog based application, but this question could be applied to any UI driven application. I have separate classes that handle state machines, file reading/writing, and hardware interfacing. All of these objects will need some type of UI control or property display/editing. In the MFC dialog applications, the dialog is the program, so it must exist until the program is closed. I've usually just put the objects in the main dialog class for the application and had the dialog class serve double duty; as both the main UI and the home for all other objects in the application. In other applications, I've created these objects globally and referenced them from wherever they were needed. Neither of these ways seem correct. The first option breaks the one class, one task rule, and the second relies on globals and also creates hidden dependencies. I could institute some type of dependency injection, but where would all these variables that I would inject reside?</p>
<p>I'm just wondering what others do to organize their programs without breaking the rules?</p>

<hr>
<p>This seems a bit bizarre to me, but as far as I can tell, this is how you do it.</p>
<p>I have a collection of objects, and I want users to select one or more of them. This says to me "form with checkboxes." My objects don't have any concept of "selected" (they're rudimentary POCO's formed by deserializing a wcf call). So, I do the following:</p>
<pre><code>public class SampleObject{
public Guid Id {get;set;}
public string Name {get;set;}
}
</code></pre>
<p>In the view:</p>
<pre><code><%
using (Html.BeginForm())
{
%>
<%foreach (var o in ViewData.Model) {%>
<%=Html.CheckBox(o.Id)%>&nbsp;<%= o.Name %>
<%}%>
<input type="submit" value="Submit" />
<%}%>
</code></pre>
<p>And, in the controller, this is the only way I can see to figure out what objects the user checked:</p>
<pre><code>public ActionResult ThisLooksWeird(FormCollection result)
{
var winnars = from x in result.AllKeys
where result[x] != "false"
select x;
// yadda
}
</code></pre>
<p>Its freaky in the first place, and secondly, for those items the user checked, the FormCollection lists its value as "true false" rather than just true. </p>
<p>Obviously, I'm missing something. I think this is built with the idea in mind that the objects in the collection that are acted upon within the html form are updated using <code>UpdateModel()</code> or through a ModelBinder. </p>
<p>But my objects aren't set up for this; does that mean that this is the only way? Is there another way to do it?</p>

<p>I am trying to use log4net in an ASP.NET application with Visual Studio 2005. I have declared an instance of the logger like so:</p>
<pre><code>Private Shared ReadOnly log As ILog = LogManager.GetLogger("")
</code></pre>
<p>I am trying to use it in the following manner:</p>
<pre><code>If log.IsDebugEnabled Then
log.Debug("Integration Services Constructed")
End If
</code></pre>
<p>Here is my configuration:</p>
<pre class="lang-xml prettyprint-override"><code><log4net>
<root>
<level value="DEBUG" />
<appender-ref ref="RollingFileAppender" />
</root>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="..\\logs\\logfile.log"/>
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="10"/>
<maximumFileSize value="1MB"/>
<staticLogFileName value="true"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline"/>
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<param name="LevelMin" value="DEBUG" />
<param name="LevelMax" value="FATAL" />
</filter>
</appender>
</log4net>
</code></pre>
<p>Unfortunately, <code>log.IsDebugEnabled</code> is always false. <br /> How do I configure log4net so that I can log only debug messages?</p>

<p>I am attempting to import mxml files that I developed with Emacs into a new project in FlexBuilder...I have created a project and manually added all my MXML and actionscript files into FlexBuilder. </p>
<p>I now can't figure out how to run the application. I believe the problem lies in the fact that FlexBuilder believes that all my mxml files are components, when in fact, they are applications...Is there a way to change this?</p>
<p>When I right click on the file the "set as default application" and "run application" is disabled...</p>
<p>Thanks.</p>

<p>Previously, settings for deployments of an ASP.NET application were stored in multiple configuration files under the Web.config config sections using a KEY/VALUE format. We are moving these 'site module options' to the database for a variety of reasons. </p>
<p>Here are the two options we are mulling over at the moment:
<br> 1. A single table with the applicationId, moduleId, and key as a Primary Key with a Value field.
<br><strong>Pros:</strong>
<br> - This mimics the file access.
<br> - It is easy to select entire sections to cache in hashtables/value objects.
<br><strong>Cons:</strong>
<br> - More difficult to update since each key needs to be updated individually.
<br> - Must cast each value if it's not a string. </p>
<p><br> 2. Individual tables for each section which separate stored procedures, classes, etc.
<br><strong>Pros:</strong>
<br> - Data is guaranteed to be consistent since the column and object types are typed.
<br> - Updating is done in one trip to the database through an explicit interface.
<br><strong>Cons:</strong>
<br> - Must change the application interface to access the
<br> - Must update the objects, database tables, and stored procedures each time something changes. </p>
<p>Do either of these sound like good ideas or is there another way I may have overlooked? </p>

<p>I'm not the best at PHP and would be extremely grateful if somebody could help. Basically I need to parse each line of a datafeed and just get each bit of information between each "|" - then I can add it to a database. I think I can handle getting the information from between the "|"'s by using explode but I need a bit of help with parsing each line from a text file as a singular. Infact to make it even more simple, I just need it to use each line of a variable, I will submit content to the variable using a textarea and a form. Any help would be greatly appreciated!</p>

<p>OK, so I readily concede that I'm a newbie when it comes to continuous integration.</p>
<p>That being said, I'm trying to set up a CC.NET environment to educate myself, but I'm having trouble finding the information I need to get the automated build portion set up.</p>
<p>As I understand it, in C# the .csproj file produced by VS 2005 and forward <em>is</em> a valid MSBuild file. To wit, I've been able to integrate the MSBuild task into CC.NET using the .csproj file, but I have a few issues with this:</p>
<ol>
<li>There's a lot going on in here that I'm not sure I really need in an automated build environment.</li>
<li>I didn't create this file. I do not understand it, and that scares me. (<a href="http://www.pragprog.com/the-pragmatic-programmer/extracts/coincidence" rel="noreferrer">Programming By Coincidence</a>)</li>
<li>Most of what is going on seems to be abstracted through <code>$(MSBuildToolsPath)\Microsoft.CSharp.targets</code></li>
<li>As a result of 1, 2, and 3, modifying the file to include something like MbUnit seems convoluted and more difficult than it needs to be. My only real option is to include it in the <code>AfterBuild</code> section, which seems kind of like a hack to me.</li>
</ol>
<p>So, a few questions for the CC.NET folks, the MSBuild folks, and the MbUnit folks.</p>
<ol>
<li>When using MSBuild, is it advisable to use the VS-generated .csproj file as the build file? Or should I create my own?</li>
<li>Should MbUnit tests be part of the MSBuild file or the CC.NET file? My research seems to suggest that they belong in the MSBuild file. If that is the case, do I create a new MSBuild .proj file and check that in to CVS in addition to the .csproj file? Or does the MbUnit task become part of my .csproj file?</li>
<li>Similar to question 2. If I add the MbUnit tests to the MSBuild file and end up using the .csproj file, is the <code>Target Name="AfterBuild"</code> really the section to add that information? Shouldn't there be a <code>Target Name="Test"</code> section? Using the VS generated .csproj file seems to prevent the second option.</li>
</ol>
<p>I know there's a lot there, but most of what I've been able to find online assumes a certain level of familiarity with these topics that I just don't have -- unless I'm mistaken, the learning curve for this stuff isn't a curve at all, it's a step function. :)</p>
<p>Edit 1: I updated the text to be a bit more concise and to address some lingering questions I've had with the answers.</p>

<p>Inspired by <a href="https://stackoverflow.com/questions/220044/which-sort-algorithm-works-best-on-mostly-sorted-data">this question</a></p>
<p>The choice of which algorithm to use to sort a collection can be made better if we know ahead of time how well sorted a collection is. Is there a way we can measure (or maintain a measurement) of how well sorted the collection is? Can we do this in such a way that the cost of maintaining or measuring how well sorted something doesn't outweigh the benefit of choosing the best sort algorithm?</p>

<p>I'm trying to find out how to read/write to the extended file properties in C#
e.g. Comment, Bit Rate, Date Accessed, Category etc that you can see in Windows explorer.
Any ideas how to do this?
EDIT: I'll mainly be reading/writing to video files (AVI/DIVX/...)</p>

<p>I'm looking for a Java library that is geared towards network math and already tested. Nothing particularly fancy, just something to hold ips and subnets, and do things like print a subnet mask or calculate whether an IP is within a given subnet. </p>
<p>Should I roll my own, or is there already a robust library for this?</p>

<p>I like to keep my websites extremely light and fast, but of course I need some kind of user tracking and analytics. </p>
<p>It seems like Google Analytics always takes significant enough processing time that I'd like to replace it with something faster (and/or hosted locally), perhaps having less features. </p>
<p>I really only care about these metrics: browser, OS, referrer, and # hits per page on a given day or week. </p>
<p>Does anyone have any good suggestions, or is Google Analytics really the best option?</p>

<p>I am trying to write a little backup program for friends and family and want it to be as simple to use a possible. I don't want to have to ask the user where to backup their data to, I just want to search for and use the first USB hard drive connected to the computer. Obtaining the unique ID of the hard drive would probably be a good idea too, just as a double check for next time the backup runs.</p>

<p>Let's say I have the following code:</p>
<pre><code>@sites = Site.find(session[:sites]) # will be an array of Site ids
@languages = Language.for_sites(@sites)
</code></pre>
<p>for_sites is a named_scope in the Language model that returns the languages associated with those sites, and languages are associated with sites using has_many through. The goal is for @languages to have a distinct array of the languages associated with the sites.</p>
<p>Instead of calling the Language object on the second line, I'd ideally like to say </p>
<pre><code>@sites.languages
</code></pre>
<p>and have the same list returned to me. Is there any way to do that cleanly in Rails 2.1 (or edge)? I know associations and named scopes can extend the array object to have attributes, but unless I'm missing something that doesn't apply here. Any plugins that do this would be welcome, it doesn't have to be in core.</p>

<p>I need to output the contents of a text field using MS Query Analyzer. I have tried this:</p>

<p>(where text is a <code>text</code> field)</p>
<p>and</p>
<pre><code>DECLARE @data VarChar(8000)
select top 1 @data = text from myTable
PRINT @data
</code></pre>
<p>The first one prints only the first 2000 or so characters and the second only prints the first 8000 characters. Is there any way to get all of the text?</p>
<p>Notes:</p>
<ul>
<li>must work with SQL Server 7</li>

<p>Can someone please let me know how to get the different segments of the three rows that are intersecting in different ways using SQL? The three rows in #t2 represent sets A,B, C - I am looking for A I B, A I C, B I C, A I B I C, A' , B', C' etc., (7 possible segments with 3 rows as in a Venn diagram) where I is the Intersection.</p>
<p>I am looking for a generic solution which can handle n number of rows in #t2.</p>
<pre><code>-- SQL Code Begin
create table #t1 (key1 int, key2 int) -- for each Key1 there can be 1 or more Key2
go
create table #t2 (row_id int identity(101, 1), key1 int) --row_id is the primary key
go
insert into #t1
select 1, 11 union select 1, 12 union select 1, 13 union select 1, 14 union
select 2, 13 union select 2, 15 union select 2, 16 union select 2, 17 union
select 3, 13 union select 3, 12 union select 3, 16 union select 3, 17
-- 1 --> 11, 12, 13, 14
-- 2 --> 13, 15, 16, 17
-- 3 --> 13, 12, 16, 17
insert into #t2 (key1)
select 1 union select 2 union select 3
-- SQL Code End
</code></pre>
<p>The output I am looking for is,</p>
<pre><code>1001 11 (A')
1001 14 (A')
1002 12 (A I C - A I B I C)
1003 13 (A I B I C)
1004 15 (B')
1005 16 (B I C - A I B I C)
1005 17 (B I C - A I B I C)
</code></pre>
<p>The output has 5 segments, instead of the possible 7 as two of them are NULL.</p>

<p>I'm trying to learn GNUMake for a small project I'm working on. So far, even the "basic" tutorials seem pretty rough and I've yet to make sense of the makefile syntax.</p>
<p>Does anyone have some good resources for an absolute beginner to get familiar with GNUMake?</p>
