<p>This is the page that I'm having. But the resize part in the section does not seem to be working. I copied most of the code from the <a href="http://www.asp.net/ajax/ajaxcontroltoolkit/samples/UpdatePanelAnimation/UpdatePanelAnimation.aspx" rel="nofollow noreferrer">Ajax site</a>. I placed a alert() in the tag (line 108) to find the value of 'b._originalHeight' and it shows up as '44'. I have also tried the code in the above-said tutorial (line 132) and that did not work either. (I'm not sure where it is getting this value from. But I need it to show all the controls on the form.</p>

<p>I have a GridView where one column is bound to an object property containing a nullable integer. I set SortExpression to the name of the property, and sorting works perfectly as long as all rows contain a value. If any rows contain null, however, I get an exception:</p>
<p>System.InvalidOperationException : Failed to compare two elements in the array. Object reference not set to an instance of an object.</p>
<p>How do I customize the sorting or comparison logic to handle the null case?</p>

<p>We have some raw voice audio that we need to distribute over the internet. We need decent quality, but it doesn't need to be of musical quality. Our main concern is usability by the consumer (i.e. what and where they can play it) and size of the download. My experience has shown that mp3s do not produce the best compression numbers for voice audio, but I am at a loss for what the best alternatives are. Ultimately we would like to automate the conversion process to allow the consumer to choose the quality vs. size level that they would like.</p>

<p>I'm trying to create a table with two columns comprising the primary key in MySQL, but I can't figure out the syntax. I understand single-column PKs, but the syntax isn't the same to create a primary key with two columns.</p>

<p>How can I find:</p>
<ol>
<li>which device driver (kernel module) controls each device?</li>
<li>which device is controlled by a device driver compiled <em>in</em> the kernel (and not as a module)</li>
<li>which device doesn't have a device driver (compiled in or as a module)?</li>
</ol>
<p>This script (adapted from another in "Linux Kernel in a Nutshell") partially resolves #1:</p>
<pre class="lang-bash prettyprint-override"><code>#!/bin/bash
for i in $(find /sys/ -name modalias); do
echo "----------------------------------"
modalias=$(cat $i)
echo "$(dirname $i) --> $modalias"
/sbin/modprobe --config /dev/null --show-depends $(cat $i) 2>&1
done
</code></pre>
<p>But there are some problems with it:</p>
<ol>
<li><p>I don't know of an <em>automated way</em> to convert
<code>/sys/devices/pci0000:00/0000:00:1e.0/0000:10:0d.0 --> pci:v00001002d0000515Esv00001028sd000001B1bc03sc00i00</code>
to
<code>10:0d.0 VGA compatible controller: ATI Technologies Inc ES1000 (rev 02)</code></p></li>
<li><p>In some cases the devices are internal to the MB and I don't even know a way to find the real name of the device. For example:</p></li>
</ol>
<pre class="lang-none prettyprint-override"><code>/sys/devices/platform/dcdbas --> platform:dcdbas

<li>When the device driver is <em>compiled in</em> (or doesn't exist) the response is <code>FATAL: Module _XXXX_ not found.</code> Indicating there is no module for the device.</li>
</ol>
<p>In some cases the driver is compiled in (e.g.)</p>
<pre><code>/sys/devices/platform/serial8250 --> platform:serial8250
FATAL: Module platform:serial8250 not found.
/sys/devices/platform/i8042 --> platform:i8042
FATAL: Module platform:i8042 not found.
</code></pre>
<p>In other cases, the driver just doesn't exist. But I don't know a way to tell the difference.</p>
<p>Does anyone know?</p>

<p>I have been asked to write a testing application that needs to test a new stored procedure on multiple rows in a database, in essence I want to do something like this:</p>
<pre><code>[Test]
public void TestSelect()
{
foreach(id in ids)
{
DataTable old = Database.call("old_stored_proc",id);
DataTable new_ = Database.call("new_stored_proc",id);
Assert.AreEqual(old.Rows[0]["column"],ne_.Rows[0]["column"]);
}
}
</code></pre>
<p>When I run this test, if 1 row doesn't match the other, the entire test fails; instead I would like to count how many times the assertion was passed and how many times it has failed. Is there a way to do this with NUnit?</p>
<p>I realize that NUnit might be overkill and this is a simple task without it...I just wanted to learn it. ;)</p>

<p>I would like this to be the ultimate discussion on how to check if a table exists in SQL Server 2000/2005 using SQL Statements.</p>
<p>Here are two possible ways of doing it. Which one is the standard/best way of doing it?</p>
<p>First way:</p>
<pre><code>IF EXISTS (SELECT 1
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE='BASE TABLE'
AND TABLE_NAME='mytablename')
SELECT 1 AS res ELSE SELECT 0 AS res;
</code></pre>
<p>Second way:</p>
<pre><code>IF OBJECT_ID (N'mytablename', N'U') IS NOT NULL
SELECT 1 AS res ELSE SELECT 0 AS res;
</code></pre>
<p><strong>MySQL</strong> provides the simple</p>
<pre><code>SHOW TABLES LIKE '%tablename%';
</code></pre>
<p>statement. I am looking for something similar.</p>

<p>I am working on a project that requires reliable access to historic feed entries which are not necessarily available in the current feed of the website. I have found several ways to access such data, but none of them give me all the characteristics I need.</p>
<p>Look at this as a brainstorm. I will tell you how much I have found and you can contribute if you have any other ideas.</p>
<ol>
<li><p><a href="http://code.google.com/apis/ajaxfeeds/" rel="nofollow noreferrer">Google AJAX Feed API</a> - will limit you to 250 items</p></li>
<li><p><a href="http://www.niallkennedy.com/blog/2005/12/google-reader-api.html" rel="nofollow noreferrer">Unofficial Google Reader API</a> - Perfect but unofficial and therefore unreliable (and perhaps quasi-illegal?). Also, the authentication seems to be tricky.</p></li>
<li><p><a href="http://spinn3r.com/" rel="nofollow noreferrer">Spinn3r</a> - Costs a lot of money</p></li>
<li><p>Spidering the <a href="http://www.archive.org" rel="nofollow noreferrer">internet archive</a> at the site of the feed - Lots of complexity, spotty coverage, only useful as a last resort</p></li>
<li><p><a href="http://www.niallkennedy.com/blog/2005/12/my-yahoo-feed-a.html" rel="nofollow noreferrer">Yahoo! Feed API</a> or <a href="http://developer.yahoo.com/search/boss/" rel="nofollow noreferrer">Yahoo! Search BOSS</a> - The first looks more like an aggregator, meaning I'd need a different registration for each feed and the second should give more access to Yahoo's data but I can find no mention of feeds.</p></li>
<li><p>(thanks to Lou Franco) <a href="http://www.bloglines.com/services/api/sync" rel="nofollow noreferrer">Bloglines Sync API</a> - Besides the problem of needing an account and being designed more as an aggregator, it does not have a way to add feeds to the account. So no retrieval of arbitrary feeds. You need to manually add them through the reader first.</p></li>
<li><p>Other search engines/blog search/whatever?</p></li>
</ol>
<p>This is a really irritating problem as we are talking about semantic information that was once out there, is still (usually) valid, yet is difficult to access reliably, freely and without limits. Anybody know any alternative sources for feed entry goodness?</p>

<p>I'm trying to load assemblies in a separate app domain, but am running into a very strange problem. Here's some code:</p>
<pre><code> public static void LoadAssembly(string assemblyPath)
{
string pathToDll = Assembly.GetCallingAssembly().CodeBase;
AppDomainSetup domainSetup = new AppDomainSetup
{
PrivateBinPath = pathToDll
};
AppDomain newDomain = AppDomain.CreateDomain("AssemblyLoader",null,domainSetup);
AssemblyLoader loader = (AssemblyLoader)newDomain.CreateInstanceFromAndUnwrap(
pathToDll,
typeof(AssemblyLoader).FullName);
}
</code></pre>
<p>AssemblyLoader is another class in the same assembly as this one, and it inherits from MarshalByRef, however for some strange reason, I get a cast exception every time I try to run this. I even hardcoded the path to the DLL instead of using GetCallingAssembly().CodeBase yet I keep getting this exception. </p>
<p>I understand it's hard to answer a question like this without actually seeing it and having more information, but maybe someone has run into a similar situation and would know the common "gotchas" and what I should look out for.</p>
<p>EDIT: The reason I don't want to load it directly is because this is just part of the code. The ultimate goal is that this class will have a method that load assemblies, gets their GUID and some other info about them and stores them in a database for a project I'm working on. Therefore, if I load this assembly in a separate app domain, I can load the others there too and then unload the app domain. No point in having all these assemblies loaded for the duration of the app, if I only need that data.</p>

<p>I have a class which implements UserControl. In .NET 2005, a Dispose method is automatically created in the MyClass.Designer.cs partial class file that looks like this:</p>
<pre><code> protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
</code></pre>
<p>If I want to add my own Dispose functionality, where would I put it? Since this file is generated, I don't want to add code here and risk it getting blown away.</p>

<p>We are managing our development with Subversion over HTTPS, Bugzilla, and Mediawiki. Some of our developers have expressed an interest in migrating to Trac, so I have to evaluate what the cost of doing so would be. </p>
<p>For both the wiki and bugzilla, we would need to either migrate the existing data into Trac or a way to integrate with trac. Having two apps to create wiki pages or log bugs would not be acceptable. Also, currently each of these applications requires a separate sign on so we would need to map each of these accounts into Trac.</p>
<p>So know of any easy methods of importing or integrating these systems with Trac and/or a tutorial for doing so?</p>

<p>Let's say I 've added a library foo.so.1.1.1 to a path that is included in <code>/etc/ld.so.conf</code>
When I run ldconfig on the system I get the links foo.so.1.1 and foo.so.1 to foo.so.1.1.1</p>
<p>How can I change the behavior to also get the foo.so link to foo.so.1.1.1?</p>

<p>When IE8 is released, will the following code work to add a conditional stylesheet?</p>
<pre><code><!--[if IE 8]>
<link rel="stylesheet" type="text/css" href="ie-8.0.css" />
<![endif]-->
</code></pre>
<p>I've read conflicting reports as to whether this works with the beta. I'm hoping someone can share their experience. Thanks.</p>

<p>We're working with a semi-centralized git repository here where I work. Each developer has their own subtree in the central git repository, so it looks something like this:</p>
<pre>master
alice/branch1
alice/branch2
bob/branch1
michael/feature
release/1.0
release/1.1</pre>
<p>Working locally in my tree I have <code>topic/feature</code>, which corresponds to <code>michael/feature</code> in the central tree.</p>
<p>I've been using</p>
<pre><code>git push origin topic/feature:michael/feature
</code></pre>
<p>to push my changes to the remote tree. However, this is cumbersome and prone to mistakes (e.g. omitting the developer name, misspelling the feature name, etc.).</p>
<p>I'm looking for a cleaner way to do this. For instance, "<code>git push</code>". I suspect that setting a different remote with a modified fetch refspec will do it, but I'm not sure how exactly to do it. I'm also not sure how to modify my current branch definitions to use the different remote.</p>
<p>My current <code>.git/config</code> looks something like:</p>
<pre>[remote "origin"]
url = git://central/git/project
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "topic/feature"]
remote = origin
merge = refs/heads/michael/project</pre>
<p><strong>Edit:</strong> I'd also like to apply this to pulls/fetches. But does the <code>branch.<name>.merge</code> take care of that?</p>
<p>I'll continue to research this and post here if I find something, but I'm hoping to get some other good ideas.</p>
<p><strong>Edit 2:</strong> I've decided I'll keep local and remote branch names the same. It appears it will be the least work and least prone to future problems.</p>

<p>I am looking for a pseudo random number generator which would be specialized to work fast when it is given a seed before generating each number. Most generators I have seen so far assume you set seed once and then generate a long sequence of numbers. The only thing which looks somewhat similar to I have seen so far is Perlin Noise, but it generates too "smooth" data - for similar inputs it tends to produce similar results.</p>
<p>The declaration of the generator should look something like:</p>
<pre><code>int RandomNumber1(int seed);
</code></pre>
<p>Or:</p>
<pre><code>int RandomNumber3(int seedX, int seedY, int seedZ);
</code></pre>
<p>I think having good RandomNumber1 should be enough, as it is possible to implement RandomNumber3 by hashing its inputs and passing the result into the RandomNumber1, but I wrote the 2nd prototype in case some implementation could use the independent inputs.</p>
<p>The intended use for this generator is to use it for procedural content generator, like generating a forest by placing trees in a grid and determining a random tree species and random spatial offsets for each location.</p>
<p>The generator needs to be very efficient (below 500 CPU cycles), because the procedural content is created in huge quantities in real time during rendering.</p>

<p>I recently began profiling an osgi java application that I am writing using VisualVM. One thing I have noticed is that when the application starts sending data to a client (over JMS), the number of loaded classes starts increasing at a steady rate. The Heap size and the PermGen size remains constant, however. The number of classes never falls, even after it stops sending data. Is this a memory leak? I think it is, because the loaded classes have to be stored somewhere, however the heap and permgen never increase even after I run the application for several hours.</p>
<p>For the screenshot of my profiling application go <a href="http://sites.google.com/site/javaperformacescreenshot/Home/profile.png" rel="noreferrer">here</a></p>

<p>I am trying to write a Windows Form and ASP.NET C# front-end and MSAccess backend for a pretty small database concept I have. </p>
<p>I have written this application once before in just MSAccess but I now need the app and database to be in different places. I have now figured out (thanks to a StackOverflow user) that ADO will be a bad choice because it has to have a connection open all of the time. </p>
<p>I bought Microsoft ADO.Net 2.0 Step-by-Step and I have read through some of it and understand (I think) the basic concepts at play in ADO.NET. (Datasets and the like)</p>
<p>Where I get confused is the actual implementation. What I want to know is do any of you know of a C# project that has a database backend which is open source that I can go look at the code and see how they did it. I find I learn better that way. The book has a CD with code examples that I may turn to, but I would rather see real code in a real app. </p>

<p>I would like to add a typing speed indicator just below the textarea we use on our contact form. It is just for fun and to give the user some interactivity with the page while they are completing the form.</p>
<p>It should display the average speed while typing and keep the last average when the keystrokes are idle. When they leave the textarea the last average should stick.</p>
<p>Ideally I would like to have a jQuery plugin if it is available.</p>
<p>[Edit] this was originally for just a few of my websites. But after I posted the question it struck me how this would be a neat feature for SO. If you agree <a href="http://stackoverflow.uservoice.com/pages/general/suggestions/32755" rel="noreferrer">vote here</a></p>

<p>I have a class holding complex scientific computations. It is set up to only allow a user to create a properly instantiated case. To properly test the code, however, requires setting internal state variables directly, since the reference documents supply this data in their test cases. Done improperly, however, it can invalidate the state.<p>
So I must have the ability, a member function, to set internal variables from the unit test programs. But I want to <b>strongly discourage</b> normal users from calling this function. (Yes, a determined user can muck with anything... but I don't want to <i>advertise</i> that there is a way to do something <i>wrong</i>.)<p>
It would be nice to be able to tell Intellisense to not show the function, for instance.<p>
The best solution I have at the moment is to just name the function something like: DangerousSet().<p>
What other options do I have?<P>
<b>Follow-Up</b><p>
I found Amy B's answer most useful to my situation. Thanks!<br>
Mufasa's suggestion to use reflection was great, but harder to implement (for me).<br>
Chris' suggestion of using a decorator was good, but didn't pan out.<br>
BFree's suggestion on XML is also good, and was already in use, but doesn't really solve the problem.<p>
Finally, BillTheLizard's suggestion that the problem is in the source documents is not something I can control. International experts publish highly technical books and journal articles for use by their community. The fact that they don't address my particular needs is a fact of life. There simply are no alternative documents.</p>

<p>I'd like to be able to add a class to images that adds a border that makes them look like a stack of photos. Anyone know how to do this?</p>
<p>Clarifications: Ideally something like the stack shown <a href="http://designreviver.com/tutorials/create-an-interactive-stack-of-photos/" rel="nofollow noreferrer">here</a> but it doesn't need to be interactive and only needs to work for a single photo. I also don't mind using javascript if needed (jQuery would be preferred though).</p>

<p>I have a Ruby on Rails application that I'm writing where a user has the option to edit an invoice. They need to be able to reassign the order of the rows. Right now I have an index column in the db which is used as the default sort mechanism. I just exposed that and allowed the user to edit it. </p>
<p>This is not very elegant. I'd like the user to be able to drag and drop table rows. I've used Scriptaculous and Prototype a bit and am familiar with them. I've done drag and drop lists, but haven't done table rows quite like this. Anyone have any suggestions for not only reordering but capturing the reorder efficiently?</p>
<p>Also, the user can dynamically create a new row in JS right now, so that row has to be reorderable as well. </p>
<p>Bonus points if it can be done with RJS instead of direct JavaScript.</p>

<p>I have created a user control to handle adding comments to certain business entities, like contacts and customers. Works great ... except for one issue.</p>
<p>I am using a ListView control to edit and delete comments, and a separate area, on the same user control to add a new comment. All of this is wrapped in an UpdatePanel.</p>
<p><img src="https://farm4.static.flickr.com/3239/2909377399_888d42b595.jpg?v=0" alt="Screenshot"></p>
<p>Here is my scenario ... the user adds a new comment ... the page does a postback, the data is successfully saved, and the ListView control is updated to show the new comment. Now, if the user <strong>refreshes</strong> the browser, it will naturally postback again and will add another duplicate record. </p>
<p>Any ideas on how best to prevent this?</p>

<p>I am hosting a WCF service in a Windows Service on one of our servers. After making it work in basicHttpBinding and building a test client in .NET (which finally worked) I went along and try to access it from PHP using the SoapClient class. The final consumer will be a PHP site so I need to make it consumable in PHP.</p>
<p>I got stumped when I had to enter the WSDL url in the constructor of the SoapClient class in the PHP code. Where is the WSDL? All I have is :</p>
<p><a href="http://172.27.7.123:8000/WordService" rel="noreferrer">http://172.27.7.123:8000/WordService</a> and
<a href="http://172.27.7.123:8000/WordService/mex" rel="noreferrer">http://172.27.7.123:8000/WordService/mex</a></p>
<p>None of these do not expose WSDL.</p>
<p>Being a newbie in WCF I might have asked a dumb thing (or I might have a wrong assumption somewhere). Please be gentle :D</p>
<p>And no, <a href="http://172.27.7.123:8000/WordService?wsdl" rel="noreferrer">http://172.27.7.123:8000/WordService?wsdl</a> does not show anything different than <a href="http://172.27.7.123:8000/WordService" rel="noreferrer">http://172.27.7.123:8000/WordService</a> :(</p>
<p>Am I forced to host it in IIS? Am I forced to use a regular WebService?</p>

<p>One of the vagaries of my development system (Codegear C++Builder) is that some of the auto-generated headers insist on having... </p>
<pre><code>using namespace xyzzy
</code></pre>
<p>...statements in them, which impact on my code when I least want or expect it.</p>
<p>Is there a way I can somehow cancel/override a previous "using" statement to avoid this.</p>
<p>Maybe...</p>

<p>I need to be able to GZip compress a file in an Excel VBA function. Specifically I need to be able to use the 'deflate' algorithm.</p>
<p>Is there a way to do this without having to exec a command line application? With no dependency on external tools the code will be more robust.</p>
<p>Ideally the code would make use of pre-installed VBA or COM library functions - I don't want to have to implement this logic myself or install DLLs etc.</p>
<p>If possible, I want installation of the function to be as simple as adding a .xla to the available Excel Add-Ins. No DLLs, EXEs, registry entries etc. required.</p>
<p><strong>Edit</strong> Can I make use of the .NET GZipStream to do this?</p>

<p>Say there are two possible solutions to a problem: the first is quick but hacky; the second is preferable but would take longer to implement. You need to solve the problem fast, so you decide to get the hack in place as quickly as you can, planning to start work on the better solution afterwards. The trouble is, as soon as the problem is alleviated, it plummets down the to-do list. You're still planning to put in the better solution at some point, but it's hard to justify implementing it right now. Suddenly you find you've spent five years using the less-than-perfect solution, cursing it the while.</p>
<p>Does this sound familiar? I know it's happened more than once where I work. One colleague describes deliberately making a bad GUI so that it wouldn't be accidentally adopted long-term. Do you have a better strategy?</p>

<p>I hate Physics, but I love software development. When I go back to school after Thanksgiving, I'll be taking two more quarters of Physics before I'm done with the horrid thing. I am currently reading postings on the F# units of measurement feature, but I've never used a language like F#. Would it be suitable to write applications so I can perhaps learn something about Physics while doing something I like?</p>
<p>I'm interested in command-line applications (even those that I can just execute and have spit out an answer without needing inputs) for things like kinematics, planar motion, Newton's Laws, gravitation, work, energy, momentum and impulse, systems of particles, rotational kinematics and dynamics, angular momentum, static equilibrium, oscillatory motion, wave motion, sound, physical optics, electrostatics, Gauss' law, electric field and potential, capacitance, resistance, DC circuits, magnetic field, Ampere's law, and inductance.</p>
<p>The reason I'm interested in F# is because of the units of measure functionality that the language provides.</p>

<p>I have a few questions about optimizing this type of load.</p>
<p>One builds a new table of data to be loaded into a partitioned table and then builds the indexes on this new table. </p>
<ol>
<li><p>Should you build the index with the COMPUTE STATISTICS option or use the Cascade option of the DBMS_Stats?</p></li>
<li><p>Should you gather stats on the table before the swap or on the partition after the swap?</p></li>
<li><p>If you do it after the swap and you specify the partition name in the parameter list, what interplay does the granularity parameter have? For instance, if I specify a partition name and then set granularity to 'GLOBAL AND PARTITION' does that do Global at all? Does it do <em>just</em> that one partition?</p></li>

<p>This is a pretty straight forward attempt. I haven't been using python for too long. Seems to work but I am sure I have much to learn. Someone let me know if I am way off here. Needs to find patterns, write the first line which matches, and then add a summary message for remaining consecutive lines which match pattern and return modified string.</p>
<p>Just to be clear...regex <code>.*Dog.*</code> would take </p>
<pre><code>Cat
Dog
My Dog
Her Dog
Mouse
</code></pre>
<p>and return </p>
<pre><code>Cat
Dog
::::: Pattern .*Dog.* repeats 2 more times.
Mouse
#!/usr/bin/env python
#
import re
import types
def remove_repeats (l_string, l_regex):
"""Take a string, remove similar lines and replace with a summary message.
l_regex accepts strings and tuples.
"""
# Convert string to tuple.
if type(l_regex) == types.StringType:
l_regex = l_regex,
for t in l_regex:
r = ''
p = ''
for l in l_string.splitlines(True):
if l.startswith('::::: Pattern'):
r = r + l
else:
if re.search(t, l): # If line matches regex.
m += 1
if m == 1: # If this is first match in a set of lines add line to file.
r = r + l
elif m > 1: # Else update the message string.
p = "::::: Pattern '" + t + "' repeats " + str(m-1) + ' more times.\n'
else:
if p: # Write the message string if it has value.
r = r + p
p = ''
m = 0
r = r + l
if p: # Write the message if loop ended in a pattern.
r = r + p
p = ''
l_string = r # Reset string to modified string.
return l_string

<p>Can someone please provide an implementation of a C function that gets invoked to dump the current stack? It's for a x86 linux system. It can be invoked in 2 ways: explicitly by another function, or after a crash (probably as a trap/int handler). The output can be either to the screen or to a file, as indicated by a parameter (handle). A clear explanation/comments of how the stack is unwound would obviously be very helpful. Thank you.</p>

<p>As part of the base class for some extensive unit testing, I am writing a helper function which recursively compares the nodes of one XmlDocument object to another in C# (.NET). Some requirements of this:</p>
<ul>
<li>The first document is the <strong>source</strong>, e.g. what I want the XML document to look like. Thus the second is the one I want to find differences in and it must not contain <em>extra</em> nodes not in the first document.</li>
<li>Must throw an exception when too many significant differences are found, and it should be easily understood by a human glancing at the description.</li>
<li>Child element order is important, attributes can be in any order.</li>
<li>Some attributes are ignorable; specifically <code>xsi:schemaLocation</code> and <code>xmlns:xsi</code>, though I would like to be able to pass in which ones are.</li>
<li>Prefixes for namespaces must match in both attributes and elements.</li>
<li>Whitespace between elements is irrelevant.</li>
<li>Elements will <em>either</em> have child elements <em>or</em> <code>InnerText</code>, but not both.</li>
</ul>
<p>While I'm scrapping something together: <strong>has anyone written such code and would it be possible to share it here?</strong></p>
<p>On an aside, what would you call the first and second documents? I've been referring to them as "source" and "target", but it feels wrong since the <strong>source</strong> is what I want the <strong>target</strong> to look like, else I throw an exception.</p>

<p>Null or empty string -- is one better than the other to represent no data in a table column? (I specifically use MySQL, but I'm thinking this is system-independent.) Are there major advantages/disadvantages to using one over the other, or is it simply programmer preference?</p>

<p>So I build an array of various dates. Birthdays, anniversaries, and holidays. I'd like to order the array by which one is happening next, essentially sort October to September (wrapping to next year)</p>
<p>so if my array is </p>
<pre><code>$a = ([0]=>"1980-04-14", [1]=>"2007-06-08",
[2]=>"2008-12-25", [3]=>"1978-11-03")
</code></pre>
<p>I'd like to sort it so it is arranged</p>
<pre><code>$a = ([0]=>"1978-11-03", [1]=>"2008-12-25",
[2]=>"1980-04-14", [3]=>"2007-06-08")
</code></pre>
<p>because the november 'event' is the one that will happen next (based on it being october right now).</p>
<p>I'm trying usort where my cmp function is </p>
<pre><code>function cmp($a, $b)
{
$a_tmp = split("-", $a);
$b_tmp = split("-", $b);
return strcmp($a_tmp[1], $b_tmp[1]);
}
</code></pre>
<p>I am not sure how to modify this to get my desired effect.</p>

<p>I am developing a small web app project (ColdFusion) and I am trying to keep my project split into multiple files during development, but deploy just one file on completion.</p>
<p>I have references to external files, for instance:</p>
<pre><code><script type="text/javascript" src="jquery-1.2.6.pack.js"></script>
<link type="text/css" rel="stylesheet" href="project.css" />
</code></pre>
<p>And when I build my project, I want to have the files included and embedded within the single finished product file.</p>
<pre><code><script type="text/javascript">eval(function(p,a,c,k,e,r) [...]</script>
<style type="text/css">div{font:normal;} [...]</style>
</code></pre>
<p>Anyway, it doesn't look like there is a basic way for Ant to do this. Anyone know?</p>

<p>I'm implementing a search algorithm (let's call it MyAlg) in a python package. Since the algorithm is super-duper complicated, the package has to contain an auxiliary class for algorithm options. Currently I'm developing the entire package by myself (and I'm not a programmer), however I expect 1-2 programmers to join the project later. This would be my first project that will involve external programmers. Thus, in order to make their lifes easier, how should I name this class: Options, OptionsMyAlg, MyAlgOptions or anything else?</p>
<p>What would you suggest me to read in this topic except for <a href="http://www.joelonsoftware.com/articles/Wrong.html" rel="nofollow noreferrer">http://www.joelonsoftware.com/articles/Wrong.html</a> ?</p>
<p>Thank you

<p>I have an application that takes the quality results for a manufacturing process and
creates graphs both to show Pareto charts of the bad, and also to show production throughput.</p>
<p>To automate the task of testing these statistical procedures I would like to deterministically be able to add records into the database and have the quality tech go to certain graphs and compare to a known good graph. But, I also would like to simulate the results so they would go into the database as if a user was running through the testing process.</p>
<p>One idea I have had is to fill a list with i number good, j number bad1, k number bad 2, etc. And then somehow randomly sort the list before insertion into the database.</p>
<p>So, my question, is there a standard algorithm to take a sorted list of values and create a randomly sorted list? </p>

<p>I'm maintaining a library that contains compiled objects that need to be linked into
a 3rd party executable. sometimes the executable has been compiled for Solaris, sometimes as a 32bit Linux Application, sometimes its a 64bit linux application.
What I'd love to do is pass one "path" to the library, and have the application then automatically pick up the right flavor of the library.
It'd be OK if it only worked on linux, so that I could just define the path in terms of the OS. </p>
<p>this particular case is for a library of PLI/VPI functions I want to link into a verilog simulator.</p>
<p>What I have now is</p>
<pre><code>root/path/${MYPLILIB_VER}/rootname/${MYPLIFLAVOR}/plilib.so
</code></pre>
<p>where flavor is one of</p>
<pre><code>solaris linux linux64
</code></pre>
<p>The flavor depends on the os, and if Linux, if running on a 64bit platform, it also depends on which version 32/64bit of the program I am running.
I'm looking for a better way.. </p>

<p>I'm currently writing a website that allows people to download Excel and text files. Is there a way to redirect to a different page when they click, so that we run javascript and do analytics (i.e. keep download count)? Currently, nothing prevents the user from simply right-clicking and saving. </p>
<p>Edit: </p>
<p>To be more specific, it would be nice for a single or double click of a file link to redirect to a temporary download page for analytics, then have the file be downloaded.</p>

<p>I have a some JPA entities that inherit from one another and uses discriminator to determine what class to be created (untested as of yet).</p>
<pre><code>@Entity(name="switches")
@DiscriminatorColumn(name="type")
@DiscriminatorValue(value="500")
public class DmsSwitch extends Switch implements Serializable {}
@MappedSuperclass
public abstract class Switch implements ISwitch {}
@Entity(name="switch_accounts")
public class SwitchAccounts implements Serializable {
@ManyToOne()
@JoinColumn(name="switch_id")
DmsSwitch _switch;
}
</code></pre>
<p>So in the SwitchAccounts class I would like to use the base class Switch because I don't know which object will be created until runtime. How can I achieve this?</p>

<p>Usually pagination queries look like this. Is there a better way instead of making two almost equal methods, one of which executing "select *..." and the other one "count *..."?</p>
<pre><code>public List<Cat> findCats(String name, int offset, int limit) {
Query q = session.createQuery("from Cat where name=:name");
q.setString("name", name);
if (offset > 0) {
q.setFirstResult(offset);
}
if (limit > 0) {
q.setMaxResults(limit);
}
return q.list();
}
public Long countCats(String name) {
Query q = session.createQuery("select count(*) from Cat where name=:name");
q.setString("name", name);
return (Long) q.uniqueResult();
}
</code></pre>

<p>I have a pretty unusual problem (for me). I am writing an application that will allow a user to change their system time forward or back either by explicit date (change my date to 6/3/1955) or by increment using buttons (go forward 1 month).</p>
<p>I'm writing this to help some of my users test some software that requires jumps like this in order to simulate real world usage of a billing system.</p>
<p>Changing the time in Delphi is of course very easy:</p>
<pre><code>SetDateTime(2008,05,21,16,07,21,00);
</code></pre>
<p>But I'm not sure if Delphi (2006) has any built in helpers for date math, which is one of my least favorite things :)</p>
<p>Any suggestions for the best way to handle this? I'd prefer to stay native as the winapi datetime calls suck.</p>
<p>Thanks!</p>

<p>I've been trying to get up to speed on some of the newer features in C# and one of them that I haven't had occasion to use is anonymous types.</p>
<p>I understand the usage as it pertains to LINQ queries and I looked at <a href="https://stackoverflow.com/questions/48668/how-should-anonymous-types-be-used-in-c">this SO post</a> which asked a similar question. Most of the examples I've seen on the net are related to LINQ queries, which is cool. I saw some somewhat contrived examples too but not really anything where I saw a lot of value. </p>
<p>Do you have a novel use for anonymous types where you think it really provides you some utility?</p>

<p>Has anyone else seen people do this:</p>
<pre><code>private string _name;
public string Name{ get{ return _name; } set{ _name = value;}}</code></pre>
<p>I understand using accessors if you are going to exercise some sort of control over how it gets set or perform some sort of function on it when there is a get. But if you are just going to do this, why not just make the variable public to begin with? Am I missing something?</p>

<p>Can someone provide a regular expression for parsing name/value pairs from a string? The pairs are separated by commas, and the value can optionally be enclosed in quotes. For example:</p>
<pre><code>AssemblyName=foo.dll,ClassName="SomeClass",Parameters="Some,Parameters"
</code></pre>

<p>I have a webpage that pulls information from a database, converts it to .csv format, and writes the file to the HTTPResponse. </p>
<pre><code>string csv = GetCSV();
Response.Clear();
Response.ContentType = "text/csv";
Response.Write(csv);
</code></pre>
<p>This works fine, and the file is sent to the client with no problems. However, when the file is sent to the client, the name of the current page is used, instead of a more friendly name (like "data.csv").</p>
<p><img src="https://ktrauberman.files.wordpress.com/2008/10/exportcsv.gif" alt="alt text"></p>
<p>My question is, how can I change the name of the file that is written to the output stream without writing the file to disk and redirecting the client to the file's url? </p>
<p><strong>EDIT: Thanks for the responses guys. I got 4 of the same response, so I just chose the first one as the answer.</strong></p>

<p>What is the easiest way to encode a PHP string for output to a JavaScript variable?</p>
<p>I have a PHP string which includes quotes and newlines. I need the contents of this string to be put into a JavaScript variable.</p>
<p>Normally, I would just construct my JavaScript in a PHP file, à la:</p>
<pre><code><script>
var myvar = "<?php echo $myVarValue;?>";
</script>
</code></pre>
<p>However, this doesn't work when <code>$myVarValue</code> contains quotes or newlines.</p>

<p>I was considering creating a separate SQLite database for certain apps on a Django project.<br>
However, I did not want to use direct SQLite access if possible.
Django-style ORM access to these database would be ideal.<br>
Is this possible?</p>
<p>Thank you.</p>

<p>I am trying to set attributes for an IFRAME html control from the code-behind aspx.cs file.</p>
<p>I came across a <a href="https://web.archive.org/web/20210128094503/http://geekswithblogs.net/ranganh/archive/2005/04/25/37635.aspx" rel="nofollow noreferrer">post</a> that says you can use FindControl to find the non-asp controls using:</p>
<p>The aspx file contains:</p>
<pre><code><iframe id="contentPanel1" runat="server" />
</code></pre>
<p>and then the code-behind file contains:</p>
<pre><code>protected void Page_Load(object sender, EventArgs e)
{
HtmlControl contentPanel1 = (HtmlControl)this.FindControl("contentPanel1");
if (contentPanel1 != null)
contentPanel1.Attributes["src"] = "http://www.stackoverflow.com";
}
</code></pre>
<p>Except that it's not finding the control, contentPanel1 is null.</p>
<hr />
<p><strong>Update 1</strong></p>
<p>Looking at the rendered html:</p>
<pre><code><iframe id="ctl00_ContentPlaceHolder1_contentPanel1"></iframe>
</code></pre>
<p>i tried changing the code-behind to:</p>
<pre><code>HtmlControl contentPanel1 = (HtmlControl)this.FindControl("ctl00_ContentPlaceHolder1_contentPanel1");
if (contentPanel1 != null)
contentPanel1.Attributes["src"] = "http://www.clis.com";
</code></pre>
<p>But it didn't help.</p>
<p>i am using a MasterPage.</p>
<hr />
<p><strong>Update 2</strong></p>
<p>Changing the aspx file to:</p>
<pre><code><iframe id="contentPanel1" name="contentPanel1" runat="server" />
</code></pre>
<p>also didn't help</p>
<hr />
<p><strong>Answer</strong></p>
<p>The answer is obvious, and unworthy of even asking the original question. If you have the aspx code:</p>
<pre><code><iframe id="contentPanel1" runat="server" />
</code></pre>
<p>and want to access the iframe from the code-behind file, you just access it:</p>
<pre><code>this.contentPanel1.Attributes["src"] = "http://www.stackoverflow.com";
</code></pre>

<p>Let's say I have a multithreaded C++ program that handles requests in the form of a function call to <code>handleRequest(string key)</code>. Each call to <code>handleRequest</code> occurs in a separate thread, and there are an arbitrarily large number of possible values for <code>key</code>.</p>
<p>I want the following behavior:</p>
<ul>
<li>Simultaneous calls to <code>handleRequest(key)</code> are serialized when they have the same value for <code>key</code>.</li>
<li>Global serialization is minimized.</li>
</ul>
<p>The body of <code>handleRequest</code> might look like this:</p>
<pre><code>void handleRequest(string key) {
KeyLock lock(key);
// Handle the request.
}
</code></pre>
<p><b>Question:</b> How would I implement <code>KeyLock</code> to get the required behavior?</p>
<p>A naive implementation might start off like this:</p>
<pre><code>KeyLock::KeyLock(string key) {
global_lock->Lock();
internal_lock_ = global_key_map[key];
if (internal_lock_ == NULL) {
internal_lock_ = new Lock();
global_key_map[key] = internal_lock_;
}
global_lock->Unlock();
internal_lock_->Lock();
}
KeyLock::~KeyLock() {
internal_lock_->Unlock();
// Remove internal_lock_ from global_key_map iff no other threads are waiting for it.
}
</code></pre>
<p>...but that requires a global lock at the beginning and end of each request, and the creation of a separate <code>Lock</code> object for each request. If contention is high between calls to <code>handleRequest</code>, that might not be a problem, but it could impose a lot of overhead if contention is low.</p>

<p>I want to allow an Excel report to be viewed embedded in a WebPage... is there a way?</p>
<ul>
<li><p>I don't want to use an ActiveX, or OWC (Office Web Components), I just want to open an existing file from the internet explorer application.</p></li>
<li><p>I don't want users to download and then open it.</p></li>
</ul>
<p>Using an iframe wouldn't be a problem, but my preliminary tests weren't successful</p>
<p>Any ideas? Is it at all possible?</p>

<p>We have a SmartClient built in C# that stubornly remains open when the PC its running on is being restarted. This halts the restart process unless the user first closes the SmartClient or there is some other manual intervention.</p>
<p>This is causing problems when the infrastructure team remotely installs new software that requires a machine reboot.</p>
<p>Any ideas for getting the SmartClient app to recognize the shutdown/restart event from Windows and gracefully kill itself?</p>
<p><strong>UPDATE:</strong>
This is a highly threaded application with multiple gui threads. yes, multiple gui threads. Its really a consolidation of many project that in and of themselves could be standalone applications - all of which are launched and managed from a single exe that centralizes those management methods and keeps track of those threads. I don't believe using background threads is an option.</p>

<p>After working for a few days with Eclipse Java I totally got addicted to pressing <kbd>Ctrl</kbd> and clicking on an identifier to go to its definition. Since then I've been looking for a way to achieve this in Visual Studio as well.</p>
<p>I realize VS has right click, Go to definition, and that <kbd>F12</kbd> does the same. I also realize that Visual Assist does something similar with <kbd>Alt</kbd> + <kbd>G</kbd>. Yet none of these are as perfect as <kbd>Ctrl</kbd> + click. </p>
<p>I've actually tried my luck for a few hours trying to write a VS plugin to do it but didn't get anywhere in the time frame I thought reasonable for this.</p>
<p>Does anyone know how this could be achieved? A ready plugin? A macro of some kind?</p>

<p>I have run across an XML Schema with the following definition:</p>
<pre><code><xs:simpleType name="ClassRankType">
<xs:restriction base="xs:integer">
<xs:totalDigits value="4"/>
<xs:minInclusive value="1"/>
<xs:maxInclusive value="9999"/>
</xs:restriction>
</xs:simpleType>
</code></pre>
<p>However, it seems to me that <code>totalDigits</code> is redundant. I am somewhat new to XML Schema, and want to make sure I'm not missing something.</p>
<p>What is the actual behavior of <code>totalDigits</code> vs. <code>maxInclusive</code>?</p>
<p>Can <code>totalDigits</code> always be represented with a combination of <code>minInclusive</code> and <code>MaxInclusive</code>? </p>
<p>How does <code>totalDigits</code> affect negative numbers?</p>

<p>It looks like I had a fundamental misunderstanding about C++ :<</p>
<p>I like the polymorphic container solution. Thank you SO, for bringing that to my attention :)</p>
<hr>
<p>So, we have a need to create a relatively generic container type object. It also happens to encapsulate some business related logic. However, we need to store essentially arbitrary data in this container - everything from primitive data types to complex classes.</p>
<p>Thus, one would immediately jump to the idea of a template class and be done with it. However, I have noticed C++ polymorphism and templates do not play well together. Being that there is some complex logic that we are going to have to work, I would rather just stick with either templates OR polymorphism, and not try to fight C++ by making it do both.</p>
<p>Finally, given that I want to do one or the other, I would prefer polymorphism. I find it much easier to represent constraints like "this container contains Comparable types" - a la java.</p>
<p>Bringing me to the topic of question: At the most abstract, I imagine that I could have a "Container" pure virtual interface that has something akin to "push(void* data) and pop(void* data)" (for the record, I am not actually trying to implement a stack).</p>
<p>However, I don't really like void* at the top level, not to mention the signature is going to change every time I want to add a constraint to the type of data a concrete container can work with.</p>
<p>Summarizing: We have relatively complex containers that have various ways to retrieve elements. We want to be able to vary the constraints on the elements that can go into the containers. Elements should work with multiple kinds of containers (so long as they meet the constraints of that particular container).</p>
<p>Edit: I should also mention that the containers themselves need to be polymorphic. That is my primary reason for not wanting to use templated C++.</p>
<p>So - should I drop my love for Java type interfaces and go with templates? Should I use void* and statically cast everything? Or should I go with an empty class definition "Element" that declares nothing and use that as my top level class in the "Element" hierarchy?</p>
<p>One of the reasons why I love stack overflow is that many of the responses provide some interesting insight on other approaches that I hadn't not have even considered. So thank you in advance for your insights and comments.</p>

<p>For my current project, I need to request XML data over a tcp/ip socket connection. For this, I am using the TcpClient class:</p>
<pre><code>Dim client As New TcpClient()
client.Connect(server, port)
Dim stream As NetworkStream = client.GetStream()
stream.Write(request)
stream.Read(buffer, 0, buffer.length)
// Output buffer and return results...
</code></pre>
<p>Now this works fine and dandy for small responses. However, when I start receiving larger blocks of data, it appears that the data gets pushed over the socket connection in bursts. When this happens, the stream.Read call only reads the first burst, and thus I miss out on the rest of the response. </p>
<p>What's the best way to handle this issue? Initially I tried to just loop until I had a valid XML document, but I found that in between stream.Read calls the underlying stream would sometimes get shut down and I would miss out on the last portion of the data.</p>

<p>I have a personal wiki that I take notes on. The wiki's pages are in a subversion working copy directory, "pages", and I set their permissions to 664, owned by www-data:www-data. My username is in the "www-data" group, so I can checkin and mess with the pages manually.</p>
<p>For a while, I had an issue because every time I ran a checkin, the files would be owned by me:www-data instead of www-data:www-data, and I would no longer be able to change the wiki files through my web interface! I solved the issue by flipping the setgid bit on the "pages" directory, but I'm still confused as to why this happened in the first place:</p>
<p>Every time I check something into subversion, it appears as if svn deletes it and recreates it. Why? Does this behavior support some functionality that I'm not aware of? Is there a way to change it?</p>
<p>Thanks!</p>

<p>I'm trying to parse objects to XML in Delphi, so I read about calling the object's ClassInfo method to get its RTTI info.</p>
<p>The thing is, this apparently only works for TPersistent objects. Otherwise, I have to specifically add a compiler directive {$M+} to the source code for the compiler to generate RTTI info.</p>
<p>So I happily added the directive, only to find that, even if it did return something from the ClassInfo call (it used to return nil), now I cannot retrieve the class' properties, fields or methods from it. It's like it created the object empty.</p>
<p>Any idea what am I missing here? Thanks!</p>

<p>I know I can get this to technically work but I'd like to implement the cleanest possible solution. Here's the situation:</p>
<p>I have a managed library which wraps an unmanaged C-style library. The C-style library functionality I'm currently wrapping does some processing involving a list of strings. The library's client code can provide a delegate, such that during the list processing, if an "invalid" scenario is encountered, the library can callback to the client via this delegate and allow them to choose the strategy to use (throw an exception, replace the invalid characters, etc.)</p>
<p>What I'd ideally like to have is all of the managed C++ isolated in one function, and then be able to call a separate function which takes only unmanaged parameters so that all of the native C++ and unmanaged code is isolated at that one point. Providing the callback mechanism to this unmanaged code is proving to be the sticking point for me.</p>
<pre><code>
#pragma managed
public delegate string InvalidStringFilter(int lineNumber, string text);
...
public IList<Result> DoListProcessing(IList<string> listToProcess, InvalidStringFilter filter)
{
// Managed code goes here, translate parameters etc.
}
#pragma unmanaged
// This should be the only function that actually touches the C-library directly
std::vector<NativeResult> ProcessList(std::vector<char*> list, ?? callback);
</code></pre>
<p>In this snippet, I want to keep all of the C-library access within ProcessList, but during the processing, it will need to do callbacks, and this callback is provided in the form of the InvalidStringFilter delegate which is passed in from some client of my managed library.</p>

<p>I have a very large file that looks like this (see below). I have two basic choices of regex to use on it (I know there may be others but I'm really trying to compare Greedy and Negated Char Class) methods.</p>
<pre><code>ftp: [^\D]{1,}
ftp: (\d)+
ftp: \d+
</code></pre>
<p><strong><em>Note: what if I took off the parense around the \d?</em></strong></p>
<p>Now + is greedy which forces backtracking but the Negated Char Class require a char-by-char comparison. Which is more efficient? Assume the file is very-very large so minute differences in processor usage will become exaggerated due to the length of the file.</p>
<p>Now that you've answered that, What if my Negated Char Class was very large, say 18 different characters? Would that change your answer?</p>
<p>Thanks.</p>

<p><a href="http://www.python.org/doc/2.5.2/lib/module-tempfile.html" rel="noreferrer">tempfile.mkstemp()</a> returns:</p>
<blockquote>
<p>a tuple containing an OS-level handle to an open file (as would be returned by os.open()) and the absolute pathname of that file, in that order.</p>
</blockquote>
<p>How do I convert that OS-level handle to a file object?</p>
<p>The <a href="http://www.python.org/doc/2.5.2/lib/os-fd-ops.html" rel="noreferrer">documentation for os.open()</a> states: </p>
<blockquote>
<p>To wrap a file descriptor in a "file
object", use fdopen().</p>
</blockquote>
<p>So I tried:</p>
<pre><code>>>> import tempfile
>>> tup = tempfile.mkstemp()
>>> import os
>>> f = os.fdopen(tup[0])
>>> f.write('foo\n')
Traceback (most recent call last):
File "<stdin>", line 1, in ?
IOError: [Errno 9] Bad file descriptor
</code></pre>

<p>What is the best way to perform a couple of tasks together and if one task fails then the next tasks should not be completed? I know if it were the database operations then I should have used Transactions but I am talking about different types of operations like the following: </p>
<p>All tasks must pass: </p>
<p>SendEmail
ArchiveReportsInDatabase
CreateAFile</p>
<p>In the above scenario all the tasks must pass or else the whole batch operation must be rollback. </p>

<p>I can do this:</p>
<pre><code>$ find .
.
./b
./b/foo
./c
./c/foo
</code></pre>
<p>And this:</p>
<pre><code>$ find . -type f -exec cat {} \;
This is in b.
This is in c.
</code></pre>
<p>But not this:</p>
<pre><code>$ find . -type f -exec cat > out.txt {} \;
</code></pre>
<p>Why not?</p>

<p>When an Event is triggered by a user in IE, it is set to the <code>window.event</code> object. The only way to see what triggered the event is by accessing the <code>window.event</code> object (as far as I know)</p>
<p>This causes a problem in ASP.NET validators if an event is triggered programmatically, like when triggering an event through jQuery. In this case, the <code>window.event</code> object stores the last user-triggered event.</p>
<p>When the <code>onchange</code> event is fired programmatically for a text box that has an ASP.NET validator attached to it, the validation breaks because it is looking at the element that fired last event, which is not the element the validator is for.</p>
<p>Does anyone know a way around this? It seems like a problem that is solvable, but from looking online, most people just find ways to ignore the problem instead of solving it.</p>
<hr>
<p><strong>To explain what I'm doing specifically:</strong><br>
I'm using a jQuery time picker plugin on a text box that also has 2 ASP.NET validators associated with it. When the time is changed, I'm using an update panel to post back to the server to do some things dynamically, so I need the onchange event to fire in order to trigger the postback for that text box.</p>
<p>The jQuery time picker operates by creating a hidden unordered list that is made visible when the text box is clicked. When one of the list items is clicked, the "change" event is fired programmatically for the text box through jQuery's <code>change()</code> method.</p>
<p>Because the trigger for the event was a list item, IE sees the <em>list item</em> as the source of the event, not the text box, like it should.</p>
<p>I'm not too concerned with this ASP.NET validator working as soon as the text box is changed, I just need the "<code>change</code>" event to be processed so my postback event is called for the text box. The problem is that the validator throws an exception in IE which stops any event from being triggered.</p>
<p>Firefox (and I assume other browsers) don't have this issue. Only IE due to the different event model. Has anyone encountered this and seen how to fix it?</p>
<hr>
<p>I've found this problem reported several other places, but they offer no solutions: </p>

<p>I'm having trouble with my php code not indenting correctly...</p>
<p>I would like my code to look like this</p>
<pre><code>if (foo)
{
print "i am indented";
}
</code></pre>
<p>but it always looks like this:</p>
<pre><code>if (foo)
{
print "i am not indented correctly";
}
</code></pre>
<p>I tired googling for similar things and tried adding the following to my .emacs, but it didn't work at all.</p>
<p>Any thoughts?</p>
<pre><code> (add-hook 'php-mode-hook
(function (lambda ()
;; GNU style
(setq php-indent-level 4
php-continued-statement-offset 4
php-continued-brace-offset 0
php-brace-offset 0
php-brace-imaginary-offset 0
php-label-offset -4))))

<p>In Java, suppose I have a String variable S, and I want to search for it inside of another String T, like so:</p>
<pre><code> if (T.matches(S)) ...
</code></pre>
<p>(note: the above line was T.contains() until a few posts pointed out that that method does not use regexes. My bad.)</p>
<p>But now suppose S may have unsavory characters in it. For instance, let S = "[hi". The left square bracket is going to cause the regex to fail. Is there a function I can call to escape S so that this doesn't happen? In this particular case, I would like it to be transformed to "\[hi".</p>

<p>I have a table with one column and about ten rows. The first column has rows with text as row headers, "header 1", "header 2". The second column contains fields for the user to type data (<em>textboxes</em> and <em>checkboxes</em>). </p>
<p>I want to have a button at the top labelled "<em>Add New...</em>", and have it create a third column, with the same fields as the first column. If the user clicks it again, it will create another blank column with fields (as in the second column).</p>
<p>Does anyone know of an effective way to manipulate the DOM to achieve this?</p>
<p>I'm experimenting with <code>div</code>'s and <code>TABLES</code> but i'm on my third day of doing this, and it feels harder than it should be.</p>

<p>If I'm deep in a nest of loops I'm wondering which of these is more efficient:</p>
<pre><code>if (!isset($array[$key])) $array[$key] = $val;
</code></pre>
<p>or</p>
<pre><code>$array[$key] = $val;
</code></pre>
<p>The second form is much more desirable as far as readable code goes. In reality the names are longer and the array is multidimensional. So the first form ends up looking pretty gnarly in my program.</p>
<p>But I'm wondering if the second form might be slower. Since the code is in one of the most frequently-executed functions in the program, I'd like to use the faster form.</p>
<p>Generally speaking this code will execute many times with the same value of "$key". So in most cases $array[$key] will already be set, and the isset() will return FALSE.</p>
<p>To clarify for those who fear that I'm treating non-identical code as if it were identical: as far as this part of the program is concerned, $val is a constant. It isn't known until run-time, but it's set earlier in the program and doesn't change here. So both forms produce the same result. And this is the most convenient place to get at $val.</p>

<p>A lot of useful features in Python are somewhat "hidden" inside modules. Named tuples (new in <a href="http://docs.python.org/whatsnew/2.6.html" rel="nofollow noreferrer">Python 2.6</a>), for instance, are found in the <a href="http://docs.python.org/library/collections.html" rel="nofollow noreferrer">collections</a> module. </p>
<p>The <a href="http://docs.python.org/library/" rel="nofollow noreferrer">Library Documentation page</a> will give you all the modules in the language, but newcomers to Python are likely to find themselves saying "Oh, I didn't know I could have done it <em>this way</em> using Python!" unless the important features in the language are pointed out by the experienced developers.</p>
<p>I'm <strong>not</strong> specifically looking for new modules in Python 2.6, but modules that can be found in this latest release.</p>

<p>.NET has System.Uri for Uris and System.IO.FileInfo for file paths. I am looking for classes which are traditionally object oriented in that they specify both meaning and behavior for the string which is used in the object's construction. What other useful string encapsulation classes exist?</p>
<p>Things such as regular expressions and StringBuilders are useful for the gross manipulation of strings but they aren't what I'm looking for.</p>

<p>I am building the diagram component in JavaScript. It has two layers rendered separately: foreground and background.</p>
<p>To determine the required size of the background:</p>
<ol>
<li>render the foreground </li>
<li>measure the height of the result</li>
<li>render the foreground and the
background together</li>
</ol>
<p>In code it looks like this:</p>
<pre><code>var foreground = renderForegroundIntoString();
parentDiv.innerHTML = foreground;
var height = parentDiv.children[0].clientHeight;
var background = renderBackgroundIntoString(height);
parentDiv.innerHTML = foreground + background;
</code></pre>
<p>Using IE7, this is a piece of cake. However, Firefox2 is not really willing to render the <code>parentDiv.innerHTML</code> right away, therefore I cannot read out the foreground height.</p>
<p>When does Firefox execute the rendering and how can I delay my background generation till foreground rendering is completed, or is there any alternative way to determine the height of my foreground elements?</p>
<p>[Appended after testing Dan's answer (thanx Dan)]</p>
<p>Within the body of the callback method (called back by <code>setTimeout(...))</code> I can see, the rendering of the <code>innerHTML</code> is still not complete. </p>

<p>I've exposed several web services in our product using Java and WS-Security. One of our customers wants to consume the web service using ColdFusion. Does ColdFusion support WS-Security? Can I get around it by writing a Java client and using that in ColdFusion?</p>
<p>(I don't know much about ColdFusion).</p>

<p>I wish to perform an experiment many different times. After every trial, I am left with a "large" set of output statistics -- let's say, 1000. I would like to store the outputs of my experiments in a table, but what's the best way...?</p>
<h3>Option 1</h3>
<p>Have a table with 1000 columns. Seems like a bad idea. What if the number of statistics one day exceeds the maximum number of columns?</p>
<h3>Option 2</h3>
<p>Have a table with three columns. Let's say, ID, StatisticType, and StatisticValue. That way, you can have as many statistics as you want. However, reading a single experiments statistics becomes more complicated. Moreover, what if different statistics are different data types??</p>
<p>Any suggestions?</p>

<p>I'm looking for a homegrown way to scramble production data for use in development and test. I've built a couple of scripts that make random social security numbers, shift birth dates, scramble emails, etc. But I've come up against a wall trying to scramble customer names. I want to keep real names so we can still use or searches so random letter generation is out. What I have tried so far is building a temp table of all last names in the table then updating the customer table with a random selection from the temp table. Like this:</p>
<pre><code>DECLARE @Names TABLE (Id int IDENTITY(1,1),[Name] varchar(100))
/* Scramble the last names (randomly pick another last name) */
INSERT @Names SELECT LastName FROM Customer ORDER BY NEWID();
WITH [Customer ORDERED BY ROWID] AS
(SELECT ROW_NUMBER() OVER (ORDER BY NEWID()) AS ROWID, LastName FROM Customer)
UPDATE [Customer ORDERED BY ROWID] SET LastName=(SELECT [Name] FROM @Names WHERE ROWID=Id)
</code></pre>
<p>This worked well in test, but completely bogs down dealing with larger amounts of data (>20 minutes for 40K rows)</p>
<p>All of that to ask, how would you scramble customer names while keeping real names and the weight of the production data?</p>
<p><strong>UPDATE:</strong> Never fails, you try to put all the information in the post, and you forget something important. This data will also be used in our sales & demo environments which are publicly available. Some of the answers are what I am attempting to do, to 'switch' the names, but my question is literally, how to code in T-SQL?</p>

<p>If I have a sorted list (say quicksort to sort), if I have a lot of values to add, is it better to suspend sorting, and add them to the end, then sort, or use binary chop to place the items correctly while adding them. Does it make a difference if the items are random, or already more or less in order?</p>

<pre><code>private IEnumerable<string> Tables

<p>Let's say I want iterate on those and write something like processing #n of #m. </p>
<p>Is there a way I can find out the value of m without iterating before my main iteration?</p>
<p>I hope I made myself clear.</p>

<p>I need to show only one element at a time when a link is clicked on. Right now I'm cheating by hiding everything again and then toggling the element clicked on. This works, unless i want EVERYTHING to disappear again. Short of adding a "Hide All" button/link what can i do? I would like to be able to click on the link again, and hide it's content.</p>
<p>EDIT: Pseudo's code would have worked, but the html here mistakenly led you to believe that all the links were in one div. instead of tracking down where they all were, it is easier to call them by their ID.</p>
<p>Here's what I have so far:</p>
<pre><code>$(document).ready(function(){
//hides everything
$("#infocontent *").hide();
//now we show them by which they click on
$("#linkjoedhit").click(function(event){
$("#infocontent *").hide();
$("#infojoedhit").toggle();
return false;
});
$("#linkgarykhit").click(function(event){
$("#infocontent *").hide();
$("#infogarykhit").toggle();
return false;
});
});
</code></pre>
<p>and the html looks like:</p>
<pre><code><div id="theircrappycode">
<a id="linkjoedhit" href="">Joe D</a><br/>
<a id="linkgarykhit" href="">Gary K</a>
</div>
<div id="infocontent">
<p id="infojoedhit">Information about Joe D Hitting.</p>
<p id="infogarykhit">Information about Gary K Hitting.</p>
</div
</code></pre>
<p>there are about 20 links like this. Because I am not coding the actual html, I have no control over the actual layout, which is horrendous. Suffice to say, this is the only way to organize the links/info.</p>
