64,759 | <p>I have a pdf file of a logo, about 1"x2" in dimension. Can anybody provide the code snippet to import that PDF logo into another PDF file using the <a href="http://framework.zend.com/manual/en/zend.pdf.html" rel="nofollow noreferrer">Zend_PDF</a> API's? </p>
<p>Ideally, I'd like to be able to place it like the PNG, TIFF or JPG objects with the Zend_Pdf_Image object. </p>
<p>In other words, I want to be able to place the little 1x2" pdf document on top of a 8.5x11" page, not use the original pdf as a background. </p>

64,781 | <p>I have a web application that receives messages through an HTTP interface, e.g.:</p>
<pre><code>http://server/application?source=123&destination=234&text=hello
</code></pre>
<p>This request contains the ID of the sender, the ID of the recipient and the text of the message.</p>
<p>This message should be processed like:</p>
<ul>
<li>finding the matching User object for both the source and the destination from the database</li>
<li>creating a tree of objects: a Message that contains a field for the message text and two User objects for the source and the destination</li>
<li>persisting this tree to a database.</li>
</ul>
<p>The tree will be loaded by other applications that I can't touch.</p>
<p>I use Oracle as the backing database and JPA with Toplink for the database handling tasks. If possible, I'd stay with these.</p>
<p>Without much optimization I can achieve ~30 requests/sec throughput in my environment. That's not much, I'd require ~300 requests/sec. So I measured where the performance bottleneck is and found that the calls to <code>em.persist()</code> takes most of the time. If I simply comment out that line, the throughput go well over 1000 requests/sec.</p>
<p>I tried to write a small test application that used simple JDBC calls to persist 1 million messages to the same database. I used batching, meaning I did 100 inserts then a commit, and repeated until all the records was in the database. I measured ~500 requests/sec throughput in this scenario, that would meet my needs.</p>
<p>It is clear that I need to optimize insert performance here. However as I mentioned earlier I would like to keep using JPA and Toplink for this, not pure JDBC.</p>
<p>Do you know a way to create batch inserts with JPA and Toplink? Can you recommend any other technique for improving JPA persist performance?</p>
<p><strong>ADDITIONAL INFO:</strong></p>
<p>"requests/sec" means here: total number of requests / total time from beginning of test to last record written to database.</p>
<p>I tried to make the calls to <code>em.persist()</code> asynchronous by creating an in-memory queue between the servlet stuff and the persister. It helped the performance greatly. However the queue did grow really fast and as the application will receive ~200 requests/second continuously, It is not an acceptable solution for me.</p>
<p>In this decoupled approach I collected requests for 100 msec and called <code>em.persist()</code> on all collected items before commiting the transaction. The EntityManagerFactory is cached between each transaction.</p>

64,786 | <p>What is your favorite method to handle errors in Bash?
The best example of handling errors I have found on the web was written by William Shotts, Jr at <a href="http://www.linuxcommand.org" rel="noreferrer">http://www.linuxcommand.org</a>. </p>
<p>He suggests using the following function for error handling in Bash:</p>
<pre><code>#!/bin/bash
# A slicker error handling routine
# I put a variable in my scripts named PROGNAME which
# holds the name of the program being run. You can get this
# value from the first item on the command line ($0).
# Reference: This was copied from <http://www.linuxcommand.org/wss0150.php>
PROGNAME=$(basename $0)
function error_exit
{
# ----------------------------------------------------------------
# Function for exit due to fatal program error
# Accepts 1 argument:
# string containing descriptive error message
# ----------------------------------------------------------------
echo "${PROGNAME}: ${1:-"Unknown Error"}" 1>&2
exit 1
}
# Example call of the error_exit function. Note the inclusion
# of the LINENO environment variable. It contains the current
# line number.
echo "Example of error with line number and message"
error_exit "$LINENO: An error has occurred."
</code></pre>
<p>Do you have a better error handling routine that you use in Bash scripts?</p>

64,813 | <p>These days, i came across a problem with Team System Unit Testing. I found that the automatically created accessor class ignores generic constraints - at least in the following case:</p>
<p>Assume you have the following class:</p>
<pre><code>namespace MyLibrary
{
public class MyClass
{
public Nullable<T> MyMethod<T>(string s) where T : struct
{
return (T)Enum.Parse(typeof(T), s, true);
}
}
}
</code></pre>
<p>If you want to test MyMethod, you can create a test project with the following test method:</p>
<pre><code>public enum TestEnum { Item1, Item2, Item3 }
[TestMethod()]
public void MyMethodTest()
{
MyClass c = new MyClass();
PrivateObject po = new PrivateObject(c);
MyClass_Accessor target = new MyClass_Accessor(po);
// The following line produces the following error:
// Unit Test Adapter threw exception: GenericArguments[0], 'T', on
// 'System.Nullable`1[T]' violates the constraint of type parameter 'T'..
TestEnum? e1 = target.MyMethod<TestEnum>("item2");
// The following line works great but does not work for testing private methods.
TestEnum? e2 = c.MyMethod<TestEnum>("item2");
}
</code></pre>
<p>Running the test will fail with the error mentioned in the comment of the snippet above. The problem is the accessor class created by Visual Studio. If you go into it, you will come up to the following code:</p>
<pre><code>namespace MyLibrary
{
[Shadowing("MyLibrary.MyClass")]
public class MyClass_Accessor : BaseShadow
{
protected static PrivateType m_privateType;
[Shadowing(".ctor@0")]
public MyClass_Accessor();
public MyClass_Accessor(PrivateObject __p1);
public static PrivateType ShadowedType { get; }
public static MyClass_Accessor AttachShadow(object __p1);
[Shadowing("MyMethod@1")]
public T? MyMethod(string s);
}
}
</code></pre>
<p>As you can see, there is no constraint for the generic type parameter of the MyMethod method.</p>
<p>Is that a bug? Is that by design? Who knows how to work around that problem?</p>

64,827 | <p>I've created a learning application using <a href="http://jimneath.org/2008/09/09/bort-base-rails-application/" rel="noreferrer">Bort</a>, which is a base app that includes Restful Authentication and RSpec. I've got it up and running and added a new object that requires users to be logged in before they can do anything(<code>before_filter :login_required</code> in the controller). [edit: I should also mention that the user <code>has_many</code> of the new class and only the user should be able to see it.]</p>
<p>I've created the new model/controller using Rspec's generators which have created a number of default tests. They all pass if there is no <code>before_filter</code> but several fail, as should be expected, once the <code>before_filter</code> is in place.</p>
<p>How do I get the generated tests to run as if there is/is not a logged in user? Do I need a whole batch of matching not logged in - redirect tests? I assume it is some sort of mocking or fixture technique but I am new to RSpec and a bit adrift. Good RSpec tutorial links would also be appreciated.</p>

64,833 | <p>I am writing a C# client that calls a web service written in Java (by another person). I have added a web reference to my client and I'm able to call methods in the web service ok.</p>
<p>The service was changed to return an array of objects, and the client does not properly parse the returned SOAP message.</p>
<pre><code>MyResponse[] MyFunc(string p)
class MyResponse
{
long id;
string reason;
}
</code></pre>
<p>When my generated C# proxy calls the web service (using SoapHttpClientProtocol.Invoke), I am expecting a MyResponse[] array with length of 1, ie a single element. What I am getting after the Invoke call is an element with id=0 and reason=null, regardless of what the service actually returns. Using a packet sniffer, I can see that the service is returning what appears to be a legitimate soap message with id and reason set to non-null values.</p>
<p>Is there some trick to getting a C# client to call a Java web service that returns someobject[] ? I will work on getting a sanitized demo if necessary.</p>
<p><strong>Edit</strong>: This is a web reference via "Add Web Reference...". VS 2005, .NET 3.0.</p>

64,860 | <p>What is the fastest, easiest tool or method to convert text files between character sets?</p>
<p>Specifically, I need to convert from UTF-8 to ISO-8859-15 and vice versa.</p>
<p>Everything goes: one-liners in your favorite scripting language, command-line tools or other utilities for OS, web sites, etc.</p>
<h2>Best solutions so far:</h2>
<p>On Linux/UNIX/OS X/cygwin:</p>
<ul>
<li><p>Gnu <a href="http://www.gnu.org/software/libiconv/documentation/libiconv/iconv.1.html" rel="noreferrer">iconv</a> suggested by <a href="https://stackoverflow.com/questions/64860/best-way-to-convert-text-files-between-character-sets#64889">Troels Arvin</a> is best used <strong>as a filter</strong>. It seems to be universally available. Example:</p>
<pre><code> $ iconv -f UTF-8 -t ISO-8859-15 in.txt > out.txt
</code></pre>
<p>As pointed out by <a href="https://stackoverflow.com/questions/64860/best-way-to-convert-text-files-between-character-sets#64991">Ben</a>, there is an <a href="http://www.iconv.com/iconv.htm" rel="noreferrer">online converter using iconv</a>.</p>
</li>
<li><p><a href="https://github.com/rrthomas/recode/" rel="noreferrer">recode</a> (<a href="http://www.informatik.uni-hamburg.de/RZ/software/gnu/utilities/recode_toc.html" rel="noreferrer">manual</a>) suggested by <a href="https://stackoverflow.com/questions/64860/best-way-to-convert-text-files-between-character-sets#64888">Cheekysoft</a> will convert <strong>one or several files in-place</strong>. Example:</p>
<pre><code> $ recode UTF8..ISO-8859-15 in.txt
</code></pre>
<p>This one uses shorter aliases:</p>
<pre><code> $ recode utf8..l9 in.txt
</code></pre>
<p>Recode also supports <em>surfaces</em> which can be used to convert between different line ending types and encodings:</p>
<p>Convert newlines from LF (Unix) to CR-LF (DOS):</p>
<pre><code> $ recode ../CR-LF in.txt
</code></pre>
<p>Base64 encode file:</p>
<pre><code> $ recode ../Base64 in.txt
</code></pre>
<p>You can also combine them.</p>
<p>Convert a Base64 encoded UTF8 file with Unix line endings to Base64 encoded Latin 1 file with Dos line endings:</p>
<pre><code> $ recode utf8/Base64..l1/CR-LF/Base64 file.txt
</code></pre>
</li>
</ul>
<p>On Windows with <a href="https://learn.microsoft.com/en-us/powershell/" rel="noreferrer">Powershell</a> (<a href="https://stackoverflow.com/questions/64860/best-way-to-convert-text-files-between-character-sets#64937">Jay Bazuzi</a>):</p>
<ul>
<li><code>PS C:\> gc -en utf8 in.txt | Out-File -en ascii out.txt</code></li>
</ul>
<p>(No ISO-8859-15 support though; it says that supported charsets are unicode, utf7, utf8, utf32, ascii, bigendianunicode, default, and oem.)</p>
<h2>Edit</h2>
<p>Do you mean iso-8859-1 support? Using "String" does this e.g. for vice versa</p>
<pre><code>gc -en string in.txt | Out-File -en utf8 out.txt
</code></pre>
<p>Note: The possible enumeration values are "Unknown, String, Unicode, Byte, BigEndianUnicode, UTF8, UTF7, Ascii".</p>

64,904 | <p>I need to support exact phrases (enclosed in quotes) in an otherwise space-separated list of terms.
Thus splitting the respective string by the space-character is not sufficient anymore.</p>
<p>Example:</p>
<pre><code>input : 'foo bar "lorem ipsum" baz'
output: ['foo', 'bar', 'lorem ipsum', 'baz']
</code></pre>
<p>I wonder whether this could be achieved with a single RegEx, rather than performing complex parsing or split-and-rejoin operations.</p>
<p>Any help would be greatly appreciated!</p>

64,958 | <p>Yacc does not permit objects to be passed around. Because the %union can only contain POD types, complex objects must be new'd and passed around by pointer. If a syntax error occurs, the yacc parser just stops running, and references to all of those created objects are lost.</p>
<p>The only solution I've come up with is that all new'd object inherit a particular base class, be added to a container when allocated, and if there is an error everything in that container can be deleted.</p>
<p>Does anyone know of any better yacc tricks to solve this problem?</p>
<p>Please don't tell me to choose a different parser.</p>

64,992 | <p>I'm working with a support person who is supposed to be able to install SSL certs on a web server he maintains. He has local admin rights to the server via a domain security group. He also has permissions on our internal CA running Windows 2003 Server Certificate Authority: "Request cert" and "Issue and Manage certs".</p>
<p>The server he's working with is running Windows 2000 SP4 / IIS 5. When he attempts to create an online server cert the IIS wizard ends with "Failed to install. Access is Denied.". The event viewer is not working properly, so I can't find any details there. I suspect the permission issue is locally and not with the CA.</p>
<p>My account is a domain admin account and I know I am able to do this operation, however I need to make this work for others that are not domain admins.</p>
<p>Any ideas why he can't perform this operation?</p>

65,008 | <p>I am experimenting with using the FaultException and FaultException<T> to determine the best usage pattern in our applications. We need to support WCF as well as non-WCF service consumers/clients, including SOAP 1.1 and SOAP 1.2 clients.</p>
<p>FYI: using FaultExceptions with wsHttpBinding results in SOAP 1.2 semantics whereas using FaultExceptions with basicHttpBinding results in SOAP 1.1 semantics. </p>
<p>I am using the following code to throw a FaultException<FaultDetails>:</p>
<pre><code> throw new FaultException<FaultDetails>(
new FaultDetails("Throwing FaultException<FaultDetails>."),
new FaultReason("Testing fault exceptions."),
FaultCode.CreateSenderFaultCode(new FaultCode("MySubFaultCode"))
);
</code></pre>
<p>The FaultDetails class is just a simple test class that contains a string "Message" property as you can see below.</p>
<p>When using wsHttpBinding the response is:</p>
<pre><code><?xml version="1.0" encoding="utf-16"?>
<Fault xmlns="http://www.w3.org/2003/05/soap-envelope">
<Code>
<Value>Sender</Value>
<Subcode>
<Value>MySubFaultCode</Value>
</Subcode>
</Code>
<Reason>
<Text xml:lang="en-US">Testing fault exceptions.</Text>
</Reason>
<Detail>
<FaultDetails xmlns="http://schemas.datacontract.org/2004/07/ClassLibrary" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<Message>Throwing FaultException&lt;FaultDetails&gt;.</Message>
</FaultDetails>
</Detail>
</code></pre>
<p></p>
<p>This looks right according to the SOAP 1.2 specs. The main/root “Code” is “Sender”, which has a “Subcode” of “MySubFaultCode”. If the service consumer/client is using WCF the FaultException on the client side also mimics the same structure, with the faultException.Code.Name being “Sender” and faultException.Code.SubCode.Name being “MySubFaultCode”.</p>
<p>When using basicHttpBinding the response is:</p>
<pre><code><?xml version="1.0" encoding="utf-16"?>
<s:Fault xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<faultcode>s:MySubFaultCode</faultcode>
<faultstring xml:lang="en-US">Testing fault exceptions.</faultstring>
<detail>
<FaultDetails xmlns="http://schemas.datacontract.org/2004/07/ClassLibrary" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<Message>Throwing FaultException&lt;FaultDetails&gt;.</Message>
</FaultDetails>
</detail>
</s:Fault>
</code></pre>
<p>This does not look right. Looking at the SOAP 1.1 specs, I was expecting to see the “faultcode” to have a value of “s:Client.MySubFaultCode” when I use FaultCode.CreateSenderFaultCode(new FaultCode("MySubFaultCode")). Also a WCF client gets an incorrect structure. The faultException.Code.Name is “MySubFaultCode” instead of being “Sender”, and the faultException.Code.SubCode is null instead of faultException.Code.SubCode.Name being “MySubFaultCode”. Also, the faultException.Code.IsSenderFault is false.</p>
<p>Similar problem when using FaultCode.CreateReceiverFaultCode(new FaultCode("MySubFaultCode")):</p>
<ul>
<li>works as expected for SOAP 1.2</li>
<li>generates “s:MySubFaultCode” instead of “s:Server.MySubFaultCode” and the faultException.Code.IsReceiverFault is false for SOAP 1.1</li>
</ul>

65,074 | <p>I've just started writing unit tests for a legacy code module with large physical dependencies using the #include directive.

<p>I've been frequently running into the problem of duplicating almost every header file with a blank version in order to separate the class I'm testing in it's entirety, and then writing substantial stub/mock/fake code for objects that will need to be replaced since they're now undefined.</p>

<p>When I run IE under a debugger, I don't see anything unusual - the debugger doesn't catch any exceptions, access violations or assertion failures, but the problem is still there - I can set a breakpoint in the control's destructor and it's never hit when I close the broswer.</p>
<p>In addition, when I load a simple HTML page that embeds multiple instances of the control I don't see the problem. The problem only appears to happen when the control is instantiated from our web application, which inserts tags dynamically into the web page - of course, not knowing what causes this problem, I don't know whether this bit of information is relevant or not, but it does seem to indicate that this might be an IE problem, since it's data dependent. </p>
<p>When I run the simple test case under the debugger, I can set a breakpoint in the control's destructor and it's hit every time. I believe this rules out a problem with the control itself (say, an error that would prevent the destructor from ever being called, like an interface leak.)</p>
<p>I do most of my testing with IE 6, but I've seen the problem occur on IE 7, as well. I haven't tested IE 8.</p>
<p>My working hypothesis right now is that there's something in the dynamic HTML code that causes the browser to leak an interface on the ActiveX control. So far, I haven't been able to produce a good test case that reproduces this outside of the application, and the application is a bit too large to make a good test case.</p>
<p>I was hoping that someone might be able to provide insight into possible IE bugs that are known to cause this kind of behavior. The answer provided below, by the way, is too general - I'm looking for a specific set of circumstances that is known to cause this. Surely someone out there has seen this before.</p>

65,164 | <p>Some 4 years back, I followed this <a href="http://msdn.microsoft.com/en-us/library/ms973825.aspx" rel="noreferrer">MSDN article</a> for DateTime usage best practices for building a .Net client on .Net 1.1 and ASMX web services (with SQL 2000 server as the backend). I still remember the serialization issues I had with DateTime and the testing effort it took for servers in different time zones.</p>
<p>My questions is this: Is there a similar best practices document for some of the new technologies like WCF and SQL server 2008, especially with the addition of new datetime types for storing time zone aware info.</p>
<p>This is the environment:</p>
<ol>
<li>SQL server 2008 on Pacific Time.</li>
<li>Web Services layer on a different time zone.</li>
<li>Clients could be using .Net 2.0 or .Net 3.5 on different time zones. If it makes it easy, we can force everyone to upgrade to .Net 3.5. :)</li>
</ol>
<p>Any good suggestions/best practices for the data types to be used in each layer?</p>

65,173 | <p>I'm trying to run PHP from the command line under <a href="https://en.wikipedia.org/wiki/Windows_XP" rel="nofollow noreferrer">Windows XP</a>.</p>
<p>That works, except for the fact that I am not able to provide parameters to my PHP script.</p>
<p>My test case:</p>
<pre><code>echo "param = " . $param . "\n";
var_dump($argv);
</code></pre>
<p>I want to call this as:</p>
<pre><code>php.exe -f test.php -- param=test
</code></pre>
<p>But I never get the script to accept my parameter.</p>
<p>The result I get from the above script:</p>
<blockquote>
<p>PHP Notice: Undefined variable: param in C:\test.php on line 2</p>
</blockquote>
<pre><code>param = ''
array(2) {
[0]=> string(8) "test.php"
[1]=> string(10) "param=test"
}
</code></pre>
<p>I am trying this using PHP 5.2.6. Is this a bug in PHP 5?</p>
<p>The parameter passing is handled in the <a href="http://us3.php.net/features.commandline" rel="nofollow noreferrer">online help</a>:</p>
<blockquote>
<p>Note: If you need to pass arguments to your scripts you need to pass -- as the first argument when using the -f switch.</p>
</blockquote>
<p>This seemed to be working under PHP 4, but not under PHP 5.</p>
<p>Under PHP 4 I could use the same script that could run on the server without alteration on the command line. This is handy for local debugging, for example, saving the output in a file, to be studied.</p>

65,266 | <p>Each time a python file is imported that contains a large quantity of static regular expressions, cpu cycles are spent compiling the strings into their representative state machines in memory.</p>

<p>Question: Is it possible to store these regular expressions in a cache on disk in a pre-compiled manner to avoid having to execute the regex compilations on each import?</p>

"cre\n_compile\np0\n(S'.*'\np1\nI0\ntp2\nRp3\n."

<p>And <code>re</code> objects are unmarshallable:</p>
<pre><code>>>> import marshal
>>> import re
>>> x = re.compile(".*")
>>> marshal.dumps(x)
Traceback (most recent call last):

65,351 | <p>I have a generic method defined like this:</p>
<pre><code>public void MyMethod<T>(T myArgument)
</code></pre>
<p>The first thing I want to do is check if the value of myArgument is the default value for that type, something like this:</p>
<pre><code>if (myArgument == default(T))
</code></pre>
<p>But this doesn't compile because I haven't guaranteed that T will implement the == operator. So I switched the code to this:</p>
<pre><code>if (myArgument.Equals(default(T)))
</code></pre>
<p>Now this compiles, but will fail if myArgument is null, which is part of what I'm testing for. I can add an explicit null check like this:</p>
<pre><code>if (myArgument == null || myArgument.Equals(default(T)))
</code></pre>
<p>Now this feels redundant to me. ReSharper is even suggesting that I change the myArgument == null part into myArgument == default(T) which is where I started. Is there a better way to solve this problem?</p>
<p>I need to support <b>both</b> references types and value types.</p>

65,434 | <p>I know there are some ways to get notified when the page body has loaded (before all the images and 3rd party resources load which fires the <strong>window.onload</strong> event), but it's different for every browser.</p>
<p>Is there a definitive way to do this on all the browsers?</p>
<p>So far I know of:</p>
<ul>
<li><p><strong>DOMContentLoaded</strong> : On Mozilla, Opera 9 and newest WebKits. This involves adding a listener to the event:</p>
<p>document.addEventListener( "DOMContentLoaded", [init function], false );</p></li>
<li><p><strong>Deferred script</strong>: On IE, you can emit a SCRIPT tag with a @defer attribute, which will reliably only load after the closing of the BODY tag.</p></li>
<li><p><strong>Polling</strong>: On other browsers, you can keep polling, but is there even a standard thing to poll for, or do you need to do different things on each browser?</p></li>
</ul>
<p>I'd like to be able to go without using document.write or external files.</p>
<p>This can be done simply via jQuery:</p>
<pre><code>$(document).ready(function() { ... })
</code></pre>
<p>but, I'm writing a JS library and can't count on jQuery always being there.</p>

65,456 | <p>I'm specifically interested in tools that can be plugged into Vim to allow CScope-style source browsing (1-2 keystroke commands to locate function definitions, callers, global symbols and so on) for languages besides C/C++ such as Java and C# (since Vim and Cscope already integrate very well for browsing C/C++). I'm not interested in IDE-based tools since I know Microsoft and other vendors already address that space -- I prefer to use Vim for editing and browsing, but but don't know of tools for C# and/or Java that give me the same power as CScope.</p>
<p>The original answer to this question included a pointer to the CSWrapper application which apparently fixes a bug that some users experience integrating Vim and CScope. However, my Vim/CScope installation works fine; I'm just trying to expand the functionality to allow using Vim to edit code in other languages.</p>

65,512 | <p>I've heard that <code>SELECT *</code> is generally bad practice to use when writing SQL commands because it is more efficient to <code>SELECT</code> columns you specifically need.</p>
<p>If I need to <code>SELECT</code> every column in a table, should I use </p>
<pre><code>SELECT * FROM TABLE
</code></pre>
<p>or </p>
<pre><code>SELECT column1, colum2, column3, etc. FROM TABLE
</code></pre>
<p>Does the efficiency really matter in this case? I'd think <code>SELECT *</code> would be more optimal internally if you really need all of the data, but I'm saying this with no real understanding of database.</p>
<p>I'm curious to know what the best practice is in this case.</p>
<p><strong>UPDATE:</strong> I probably should specify that the only situation where I would really <em>want</em> to do a <code>SELECT *</code> is when I'm selecting data from one table where I know all columns will always need to be retrieved, even when new columns are added. </p>
<p>Given the responses I've seen however, this still seems like a bad idea and <code>SELECT *</code> should never be used for a lot more technical reasons that I ever though about.</p>

65,524 | <p>What is the best way to generate a Unique ID from two (or more) short ints in C++? I am trying to uniquely identify vertices in a graph. The vertices contain two to four short ints as data, and ideally the ID would be some kind of a hash of them. Prefer portability and uniqueness over speed or ease. </p>
<p>There are a lot of great answers here, I will be trying them all tonight to see what fits my problem the best. A few more words on what I'm doing. </p>
<p>The graph is a collection of samples from an audio file. I use the graph as a Markov Chain to generate a new audio file from the old file. Since each vertex stores a few samples and points to another sample, and the samples are all short ints, it seemed natural to generate an ID from the data. Combining them into a long long sounds good, but maybe something as simple as just a 0 1 2 3 <code>generateID</code> is all I need. not sure how much space is necessary to guarantee uniqueness, if each vertex stores 2 16 bit samples, there are 2^32 possible combinations correct? and so if each vertex stores 4 samples, there are 2^64 possible combinations? </p>
<p>Library and platform specific solutions not really relevant to this question. I don't want anyone else who might compile my program to have to download additional libraries or change the code to suit their OS. </p>

65,530 | <p>In Tomcat 5.5 the server.xml can have many connectors, typically port only 8080, but for my application a user might configure their servlet.xml to also have other ports open (say 8081-8088). I would like for my servlet to figure out what socket connections ports will be vaild (During the Servlet.init() tomcat has not yet started the connectors.) </p>
<p>I could find and parse the server.xml myself (grotty), I could look at the thread names (after tomcat starts up - but how would I know when a good time to do that is? ) But I would prefer a solution that can execute in my servlet.init() and determine what will be the valid port range. Any ideas? A solution can be tightly bound to Tomcat for my application that's ok.</p>

65,566 | <p>I have a control that, upon postback, saves form results back to the database. It populates the values to be saved by iterating through the querystring. So, for the following SQL statement (vastly simplified for the sake of discussion)...</p>
<pre><code>UPDATE MyTable
SET MyVal1 = @val1,
MyVal2 = @val2
WHERE @id = @id
</code></pre>
<p>...it would cycle through the querystring keys thusly:</p>
<pre><code>For Each Key As String In Request.QueryString.Keys
Command.Parameters.AddWithValue("@" & Key, Request.QueryString(Key))
Next
</code></pre>
<p>HOWEVER, I'm now running into a situation where, under certain circumstances, some of these variables may not be present in the querystring. If I don't pass along val2 in the querystring, I get an error: <code>System.Data.SqlClient.SqlException: Must declare the scalar value "@val2"</code>.</p>
<p>Attempts to detect the missing value in the SQL statement...</p>
<pre><code>IF @val2 IS NOT NULL
UPDATE MyTable
SET MyVal1 = @val1,
MyVal2 = @val2
WHERE @id = @id
</code></pre>
<p>... have failed.</p>
<p>What's the best way to attack this? Must I parse the SQL block with RegEx, scanning for variable names not present in the querystring? Or, is there a more elegant way to approach?</p>
<p>UPDATE: Detecting null values in the VB codebehind defeats the purpose of decoupling the code from its context. I'd rather not litter my function with conditions for every conceivable variable that might be passed, or not passed.</p>

65,651 | <p>I'm a longtime Java programmer working on a PHP project, and I'm trying to get PHPUnit up and working. When unit testing in Java, it's common to put test case classes and regular classes into separate directories, like this -</p>
<pre><code>/src
MyClass.java
/test
MyClassTest.java
</code></pre>
<p>and so on.</p>
<p>When unit testing with PHPUnit, is it common to follow the same directory structure, or is there a better way to lay out test classes? So far, the only way I can get the "include("MyClass.php")" statement to work correctly is to include the test class in the same directory, but I don't want to include the test classes when I push to production.</p>

65,724 | <p>As everyone knows, the <a href="http://en.wikipedia.org/wiki/Visual_C%2B%2B" rel="nofollow noreferrer">Visual C++</a> runtime marks uninitialized or just freed memory blocks with special non-zero markers. Is there any way to disable this behavior entirely without manually setting all uninitialized memory to zeros? It's causing havoc with my valid not null checks, since <code>0xFEEEFEEE != 0</code>.</p>
<p>Hrm, perhaps I should explain a bit better. I create and initialize a variable (via new), and that all goes just fine. When I free it (via delete), it sets the pointer to <code>0xFEEEFEEE</code> instead of <code>NULL</code>. When I insert a proper check for <code>NULL</code>, as all good programs that manage their own memory should, I come up with problems as <code>0xFEEEFEEE</code> passes a <code>NULL</code> check without problems. Is there any good way, other than manually setting all pointers to <code>NULL</code> when deleting them, to detect when memory has already been freed? I would prefer to not use <a href="http://en.wikipedia.org/wiki/Boost_C%2B%2B_Libraries" rel="nofollow noreferrer">Boost</a> simply because I don't want the overhead, small though it may be, since that's the only thing I'd be using Boost for.</p>

I have become quite accustomed to writing unit tests in Java using JUnit but was at a loss as to the best way to write unit tests for existing code (which needed refactoring) as well as new code added to the system.</p>
<p>Are there any projects out there that make unit testing plain C code as easy as unit testing Java code with JUnit? Any insight that would apply specifically to embedded development (cross-compiling to arm-linux platform) would be greatly appreciated.</p>

Thingy 4: <input class="b" type="checkbox" name="four" />

65,925 | <p>From time to time am I working in a completely disconnected environment with a Macbook Pro. For testing purposes I need to run a local DNS server in a VMWare session. I've configured the lookup system to use the DNS server (/etc/resolve.conf and through the network configuration panel, which is using configd underneath), and commands like "dig" and "nslookup" work. For example, my DNS server is configured to resolve www.example.com to 127.0.0.1, this is the output of "dig www.example.com":</p>
<pre><code>; <<>> DiG 9.3.5-P1 <<>> www.example.com
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 64859

</code></pre>
<p>Unfortunately, if I try to ping or setup a connection in a browser, the DNS name is not resolved. This is the output of "ping www.example.com":</p>
<pre><code>ping: cannot resolve www.example.com: Unknown host
</code></pre>
<p>It seems that those tools, that are more integrated within Mac OS X 10.4 (and up), are not using the "/etc/resolv.conf" system anymore. Configuring them through scutil is no help, because it seems that if the wireless or the buildin ethernet interface is <strong>inactive</strong>, basic network functions don't seem to work.</p>
<p>In Linux (for example Ubuntu), it is possible to turn off the wireless adapter, without turning of the network capabilities. So in Linux it seems that I can work completely disconnected.</p>
<p>A solution could be using an ethernet loopback connector, but I would rather like a software solution, as both Windows and Linux don't have this problem.</p>

65,940 | <p>This should be simple. I'm trying to import data from Access into SQL Server. I don't have direct access to the SQL Server database - it's on GoDaddy and they only allow web access. So I can't use the Management Studio tools, or other third-party Access upsizing programs that require remote access to the database.</p>
<p>I wrote a query on the Access database and I'm trying to loop through and insert each record into the corresponding SQL Server table. But it keeps erroring out. I'm fairly certain it's because of the HTML and God knows what other weird characters are in one of the Access text fields. I tried using CFQUERYPARAM but that doesn't seem to help either.</p>
<p>Any ideas would be helpful. Thanks.</p>

65,994 | <p>I want to use a file to store the current version number for a piece of customer software which can be used by a start-up script to run the binary in the correct directory.</p>
<p>For Example, if the run directory looks like this:</p>
<pre><code>.
..
1.2.1
1.2.2
1.3.0
run.sh
current_version
</code></pre>
<p>And current_version contains:</p>
<pre><code>1.2.2
</code></pre>
<p>I want <code>run.sh</code> to descend into 1.2.2 and run the program <code>foo</code>.</p>
<p>The current solution is this:</p>
<pre><code>#!/bin/sh
version = `cat current_version`
cd $version
./foo
</code></pre>
<p>It works but is not very robust. It does not check for file existence, cannot cope with multiple lines, leading spaces, commented lines, blank files, etc.</p>
<p>What is the most survivable way to do this with either a shell or perl script?</p>

66,006 | <p>Is it possible to have XML-embedded JavaScript executed to assist in client-side (browser-based) XSL transformations? How is it done and how official is it?</p>
<p>Microsoft's XML DOM objects allow this on the server-side (i.e. in ASP/ASP.NET).</p>
<p><strong>Clarification:</strong> I do not mean HTML DOM scripting performed <em>after</em> the document is transformed, nor do I mean XSL transformations <em>initiated</em> by JavaScript in the browser (e.g. what the W3Schools page shows). I am referring to actual script blocks located within the XSL during the transformation.</p>

<p>So: answer with one of your "Gotcha"s!</p>
<p>I'll start:
Under ASP.NET (VB), performing a Response.Redirect inside a try/catch block does not stop execution of the current Response, which can lead to two concurrent Responses executing against the same Session.</p>

66,164 | <p>I'm responsible for some test database servers. Historically, too many other poeple have access to them. They run on <code>SQL Server 2005</code>. </p>
<p>I've been writing queries and wrapping them in scripts so I can run a regular audit of rights. Finding out which users had Administrator rights on the server itself was fine, as was finding out who had the <code>sysadmin</code> role on their login - it was a single line query for the latter.</p>
<p>But how to find out which logins have a User Mapping to a particular (or any) database? </p>
<p>I can find the <code>sys.database_principals</code> and <code>sys.server_principals</code> tables. I have located the <code>sys.databases table</code>. I haven't worked out how to find out which users have rights on a database, and if so, what. </p>
<p>Every Google search brings up people manually using the User Mapping pane of the Login dialog, rather than using a query to do so. Any ideas?</p>
