241,453 | <p>I'm experimenting with JavaFX making a small game. </p>
<p>I want to add sound.
How?</p>
<p>I tried <code>MediaPlayer</code> with <code>media</code> defined with relative <code>source</code> attribute like:</p>
<pre><code>attribute media = Media{
source: "{__FILE__}/sound/hormpipe.mp3"
}
attribute player = MediaPlayer{
autoPlay:true
media:media
}
</code></pre>
<p>It doesn't play.
I get </p>
<blockquote>

241,454 | <p>What is the best way to manage a database connection in a Java servlet?</p>
<p>Currently, I simply open a connection in the <code>init()</code> function, and then close it in <code>destroy()</code>. </p>
<p>However, I am concerned that "permanently" holding onto a database connection could be a bad thing. </p>
<p>Is this the correct way to handle this? If not, what are some better options?</p>
<p>edit: to give a bit more clarification: I have tried simply opening/closing a new connection for each request, but with testing I've seen performance issues due to creating too many connections.</p>
<p>Is there any value in sharing a connection over multiple requests? The requests for this application are almost all "read-only" and come fairly rapidly (although the data requested is fairly small).</p>

241,467 | <p>As title. I didn't find one via google, at any rate.</p>
<p>Update: thanks for the links from the two answers; this is very useful, but not what I was after - I am curious to see whether it is possible to query an IRepository backed by memcached (or some other distributed cache), backed by a RDBMS. I've really no idea how that might work in practise; I don't know very much about the internals of either distributed caches or LINQ providers.</p>
<p>I'm maybe envisaging something like the cache LINQ provider generating cache-keys based on the query automatically (where query could be Expression> or some kind of Specification pattern implementation), and basically can be plumped down inbetween my app and my DB. Does that sound useful?</p>

241,470 | <p>I am designing a simple internal framework for handling time series data.
Given that LINQ is my current toy hammer, I want to hit everything with it.</p>
<p>I want to implement methods in class TimeSeries (Select(), Where() and so on) so that I can use LINQ syntax to handle time series data</p>
<p>Some things are straight forward, e.g. (from x in A select x+10), giving a new time series.</p>
<p>What is the best syntax design for combining two or more time series?
(from a in A from b in B select a+b) is not great, since it expresses a nested loop.
Maybe some join? This should correspond to join on the implicit time variable.
(What I have in mind corresponds to the lisp 'zip' function)</p>
<hr>
<p><strong>EDIT:</strong> <em>Some clarification is necessary.</em></p>
<p>A time series is a kind of function depending on time, e.g. stock quotes.
A combination of time series could be the difference between two stock prices, as a function of time.</p>
<pre><code>Stock1.MyJoin(Stock2, (a,b)=>a-b)
</code></pre>
<p>is possible, but can this be expressed neatly using some LINQ syntax?
I am expecting to implement LINQ methods in <code>class MyTimeSeries</code> myself.</p>

241,507 | <p>I think the title pretty much says it all... I'm looking to implement an interface similar to the standard OS X sidebar used in all the above mentioned programs, and I'm wondering if anybody has any thoughts as to the easiest way to do it, namely about what view to use for the left hand selection pane. Really I don't think I even need the hierarchical component as seen in the apple apps, I just need a good looking flat list of choices which determine what's shown in the right hand pane.</p>
<p>The obvious start is a vertical split layout view, but beyond that I'm not entirely sure where to go. A collection view with only one column or something like that?</p>

<p>When I click the Web Part Gallery and hit new, both articles say that the web part should show up in the list.</p>
<p>I have tried every possible way that I can think, but my web part will not show up in that list. Is there a step that I missed somewhere? Are there permissions that I should be thinking about? How exactly does Sharepoint recognize that there is a new web part. Is it simply from having the assembly placed in the BIN directory, or is it from adding the control in the safe list of web.config?</p>
<p>I've added it to the safe controls list. I've tried every different combination that I could think of, but nothing has worked.</p>
<p>Do I need to rename the .DLL assembly to something else?</p>
<p>For the life of me I cannot figure this out.</p>

241,526 | <p>I've been tasked with build an accessible RSS feed for my company's job listings. I already have an RSS feed from our recruiting partner; so I'm transforming their RSS XML to our own proxy RSS feed to add additional data as well limit the number of items in the feed so we list on the latest jobs.</p>
<p>The RSS validates via feedvalidator.org (with warnings); but the problem is this. Unfortunately, no matter how many times I tell them not to; my company's HR team directly copies and pastes their Word documents into our Recruiting partners CMS when inserting new job listings, leaving WordML in my feed. I believe this WordML is causing issues with Feedburner's BrowserFriendly feature; which we want to show up to make it easier for people to subscribe. Therefore, I need to remove the WordML markup in the feed.</p>
<p>Anybody have experience doing this? Can anyone point me to a good solution to this problem?</p>
<p>Preferably; I'd like to be pointed to a solution in .Net (VB or C# is fine) and/or XSL.</p>
<p>Any advice on this is greatly appreciated.</p>
<p>Thanks.</p>

241,539 | <p>I am extending a class defined in a library which I cannot change:</p>
<pre><code>public class Parent
{
public void init(Map properties) { ... }
}
</code></pre>
<p>If I am defining a class 'Child' that extends Parent and I am using Java 6 with generics, what is the best way to override the init method without getting unchecked warnings?</p>
<pre><code>public class Child extends Parent
{
// warning: Map is a raw type. References to generic type Map<K,V> should be parameterized
public void init(Map properties) { }
}
</code></pre>
<p>If I add generic parameters, I get:</p>
<pre><code> // error: The method init(Map<Object,Object>) of type Child has the same erasure as init(Map) of type Parent but does not override it
public void init(Map<Object,Object>) { ... }
// same error
public void init(Map<? extends Object,? extends Object>) { ... }
// same error
public void init(Map<?,?>) { ... }
</code></pre>
<p>This error occurs regardless of whether I use a specific type, a bounded wildcard, or an unbounded wildcard. Is there a correct or idiomatic way to override a non-generic method without warnings, and without using @SuppressWarnings("unchecked")?</p>

If I were to choose a particular open source license, what do you actually have to do to make it applicable to your software?

241,622 | <p>I am not as familiar with Oracle as I would like to be. I have some 250k records, and I want to display them 100 per page. Currently I have one stored procedure which retrieves all quarter of a million records to a dataset using a data adapter, and dataset, and the dataadapter.Fill(dataset) method on the results from the stored proc. If I have "Page Number" and "Number of records per page" as integer values I can pass as parameters, what would be the best way to get back just that particular section. Say, if I pass 10 as a page number, and 120 as number of pages, from the select statement it would give me the 1880th through 1200th, or something like that, my math in my head might be off. </p>
<p>I'm doing this in .NET with C#, thought that's not important, if I can get it right on the sql side, then I should be cool. </p>
<p>Update: I was able to use Brian's suggestion, and it is working great. I'd like to work on some optimization, but the pages are coming up in 4 to 5 seconds rather than a minute, and my paging control was able to integrate in very well with my new stored procs. </p>

241,631 | <p>I'm writing a web application that <em>dynamically</em> creates URL's based off of some input, to be consumed by a client at another time. For discussion sake these URL's can contain certain characters, like a <strong>forward slash (i.e. '/')</strong>, which should not be interpreted as part of the actual URL, but just as an argument. For example:</p>
<pre>http://mycompany.com/PartOfUrl1/PartOfUrl2/ArgumentTo/Url/GoesHere</pre>
<p>As you can see, the <strong>ArgumentTo/Url/GoesHere</strong> does indeed have forward slashes but these should be <em>ignored or escaped</em>.</p>
<p>This may be a bad example but the question in hand is more general and applies to other <em>special characters</em>.</p>
<h3>So, if there are pieces of a URL that are just <em>argument</em>s and should not be used to resolve the actual web request, what's a good way of handling this?</h3>
<h1>Update:</h1>
<p>Given some of the answers I realized that I failed to point out a few pieces that hopefully will help clarify.</p>
<p>I would like to keep this fairly language agnostic as it would be great if the client could just make a request. For example, if the client knew that it wanted to pass <strong>ArgumentTo/Url/GoesHere</strong>, it would be great if that could be <em>encoded</em> into a <em>unique</em> string in which the server could turn around and <em>decode</em> it to use.</p>
<p>Can we assume that similar functions like HttpUtility.HtmlEncode/HtmlDecode in the .NET Framework are available on other systems/platforms? The URL does not have to be <em>pretty</em> by any means so having <em>real words</em> in the path does not really matter.</p>
<h3>Would something like a base64 encoding of the argument work?</h3>
<p>It seems that base64 encoding/decoding is fairly readily available on any platform/language.</p>

241,645 | <p>I have the Profile, CCK, and Views2 modules installed on a Drupal 6 site. I added a string field to the user profile. I can filter easily on preset values, thru the Views GUI builder, really nicely. However, I'd like the filter criteria to be dynamically set based on other environment variables (namely the <code>$_SERVER['SERVER_NAME']</code>).</p>
<p>Is there a basic 'How-to-write-a-custom-drupal-views-filter' somewhere out there? I've been looking thru the documentation, but it's not obvious to my simple mind on how to do it.</p>

241,691 | <p>Rather than scraping a Ruby version of this algorithm off the net I wanted to create my own based on its description <a href="http://en.wikipedia.org/wiki/Sieve_of_Eratosthenes" rel="noreferrer">here</a>. However I cannot figure out two things</p>
<pre><code>def primeSieve(n)
primes = Array.new
for i in 0..n-2
primes[i] = i+2
end
index = 0
while Math.sqrt(primes.last).ceil > primes[index]
(primes[index] ** 2).step(primes.length - 1, primes[index])
{|x| x % primes[index] == 0 ? primes.delete(x) : ""}
index += 1
end
primes
end
</code></pre>
<ol>
<li>Why it doesn't iterate to the end of the array?</li>
<li>According to the description in the link above the loop should be broken out of when the squareroot of the last element in the array is greater than the current prime - mine does this one before. </li>
</ol>
<p>I'm fairly sure it has something to do with the delete operation modifying the length of the array. For example my function currently yields 2,3,5,7,9,10 when I enter n=10 which is obviously not correct. Any suggestions on how I can go about alterating this to make it work like it's supposed to?</p>

241,715 | <p>I am writing PHP code where I want to pass the session id myself using POST. I don't want a cookie to store the session, as it should get lost when the user gets out of the POST cycle.</p>
<p>PHP automatically sets the cookie where available. I learned it is possible to change this behaviour by setting <code>session.use_cookies</code> to 0 in <code>php.ini</code>. Unfortunately, I don't have access to that file and I also wouldn't want to break the behaviour of other scripts running on the same server.</p>
<p>Is there a way to disable or void the session cookie inside the PHP script?</p>
<p><strong>EDIT:</strong> As the proposed solutions don't work for me, I used $_SESSION = array() at positions in the code where I found the session should be invalidated.</p>

241,746 | <p>In a database prototype, I have a set of fields (like name, description, status) that are required in multiple, functionally different tables.</p>
<p>These fields always have the same end user functionality for labeling, display, search, filtering etc. They are not part of a foreign key constraint. How should this be modeled?</p>
<p>I can think of the following variants:</p>
<ul>
<li><p>Each table gets all these attributes. In this case, how would you name them? The same, in each table, or with a table name prefix (like usrName, prodName)</p></li>
<li><p>Move them into a table Attributes, add a foreign key to the "core" tables, referencing Attributes.PK</p></li>
<li><p>As above, but instead of a foreign key, use the Attributes.PK as PK in the respective core table as well.</p></li>

241,822 | <p>I'm preparing a class on Visual Basic 2005 targeting Visual Basic 6 programmers migrating to the .NET platform.</p>
<p>My primary concern is to teach my students the best practices for developing in .NET, and I am wondering about whether to consider the use of the VB runtime functions VB.NET legitimate or not.</p>
<p>I have read that many of the VB functions in VB.NET actually invoke methods on the .NET Framework, so it appears they exist primarily to ease the transition from earlier versions of Visual Basic to VB.NET. However, <a href="http://blogs.msdn.com/vbteam/" rel="nofollow noreferrer">the VB.NET team</a> seems to recommend to use them whenvever possible since they claim they put some optimizations in there on top of the .NET framework APIs.</p>
<p>What's your take on this? </p>

241,839 | <p>I need to choose a database management system (DBMS) that uses the least amount of main memory since we are severely constrained. Since a DBMS will use more and more memory to hold the index in main memory, how exactly do I tell which DBMS has the smallest memory footprint? </p>
<p>Right now I just have a memory monitor program open while I perform a series of queries we'll call X. Then I run the same set of queries X on a different DBMS and see how much memory is used in its lifetime and compare with the other memory footprints. </p>

241,857 | <p>I'm trying to use XPath to parse an XML document. One of my NSXMLElement's looks like the following, hypothetically speaking:</p>
<pre><code><foo bar="yummy">
</code></pre>
<p>I'm trying to get the value for the attribute bar, however any interpretation of code I use, gives me back bar="woo", which means I need to do further string processing in order to obtain access to woo and woo alone.</p>
<p>Essentially I'm doing something like</p>
<pre><code>NSArray *nodes = [xmlDoc nodesForXPath:@"foo/@bar" error:&error];
xmlElement = [nodes objectAtIndex:0];
</code></pre>
<p>Is there anyway to write the code above to just give me yummy, versus bar="yummy" so I can relieve myself of parsing the string?</p>
<p>Thanks.</p>
<hr>
<p>Assuming TouchXML is being used, is there still anyway to obtain similar results? As in grabbing just the value for the attribute, without the attribute="value"? That results in then further having to parse the string to get the value out.</p>

241,882 | <p>I'm trying to do an image capture on a high end Nokia phone (N95). The phone's internal camera is very good (4 megapixels) but in j2me I only seem to be able to get a maximum of 1360x1020 image out. I drew largely from this example <a href="http://developers.sun.com/mobility/midp/articles/picture/" rel="nofollow noreferrer">http://developers.sun.com/mobility/midp/articles/picture/</a></p>
<p>What I did was start with 640x480 and increase the width and height by 80 and 60, respectively until it failed. The line of code is:</p>
<p>jpg = mVideoControl.getSnapshot("encoding=jpeg&quality=100&width=" + width + "&height=" + height);</p>
<p>So the two issues are:
1. The phone throws an exception when getting an image larger than 1360x1020.
2. The higher resolution images appear to be just smoothed versions of the smaller ones. E.g. When I take a 640x480 image and increase it in photoshop I can't tell the difference between this and one that's supposedly 1360x1020.</p>
<p>Is this a limitation of j2me on the phone? If so does anyone know of a way to get a higher resolution from within a j2me application and/or how to access the native camera from within another application?</p>

241,892 | <p>I'm investigating SUDS as a SOAP client for python. I want to inspect the methods available from a specified service, and the types required by a specified method.</p>
<p>The aim is to generate a user interface, allowing users to select a method, then fill in values in a dynamically generated form.</p>
<p>I can get some information on a particular method, but am unsure how to parse it:</p>
<pre><code>client = Client(url)
method = client.sd.service.methods['MyMethod']
</code></pre>
<p>I am unable to <strong>programmaticaly</strong> figure out what object type I need to create to be able to call the service</p>
<pre><code>obj = client.factory.create('?')
res = client.service.MyMethod(obj, soapheaders=authen)
</code></pre>
<p>Does anyone have some sample code?</p>

241,936 | <p>The deceptively simple foundation of dynamic code generation within a C/C++ framework has already been covered in <a href="https://stackoverflow.com/questions/45408/">another question</a>. Are there any gentle introductions into topic with code examples? </p>
<p>My eyes are starting to bleed staring at highly intricate open source JIT compilers when my needs are much more modest.</p>
<p>Are there good texts on the subject that don't assume a doctorate in computer science? I'm looking for well worn patterns, things to watch out for, performance considerations, etc. Electronic or tree-based resources can be equally valuable. You can assume a working knowledge of (not just x86) assembly language.</p>

241,953 | <p>I'm using an <em>Edit in Place</em> jquery plugin which needs to post the data to a script that will do the actual database update.</p>
<p>The URL to this update script is easily viewable in the html source as well as with Firebug, so I need to add some sort of authentication check before the update is processed. This is of course so the user can't just pass in any old userid / field / value they want and mess with other people's records.</p>
<p>I was initially passing their username and password in as well, but this isn't ideal as it's in a GET request so it's all in the URL. The site itself is SSL at least, but still not a best practice by any stretch.</p>
<p>What's the best way to authenticate this type of update?</p>
<p>FWIW, the update script is in PHP, and the Edit in Place plugin is: <a href="http://www.appelsiini.net/projects/jeditable" rel="nofollow noreferrer">jeditable</a>.</p>
<p><strong>Edit:</strong> To clarify: The actual data payload is POSTed to the script, but the edit in place plugin has no explicit method for authentication, so I was passing the authentication as part of the URL to the update script, which was then taking those variables via GET and using them to check.</p>
<p><strong>Edit 2:</strong> Yes, I can access the session info from the update script, so I've decided to just pull the previously saved User ID and using that in the db update statement. That would appear to be the most secure method.</p>

241,955 | <p>I find myself writing code that looks like this a lot:</p>

affected_items.insert(some_constant_id);

for (set<int>::iterator it = affected_items.begin(); it != affected_items.end(); it++)
{
switch(*it)
{
case some_constant_id:
RunSomeFunction(with, these, params);
break;
case some_other_constant_id:
RunSomeOtherFunction(with, these, other, params);
break;
// etc...
}
}

<p>The reason I end up writing this code is that I need to only run the functions in the second loop once even if I've received multiple key codes that might cause them to run.</p>
<p>This just doesn't seem like the best way to do it. Is there a neater way?</p>

241,991 | <p>We have a weird intermittent problem with saving from Word 2007 to our SharePoint 2007 (MOSS) document libraries that gives a dialog box that never goes away - it is titled "Content Types" and the message "Getting list of available content types..." with a green progress-type bar that keeps scrolling. It happens a lot on our training server (self-contained virtual machine with separate SQL Server) but more worryingly is happening on our live production server (which is in a medium server farm arrangement - web application server, another server for search/indexing and a SQL Server). All servers in the farms are 64 bit.</p>
<p>It is strangely random - the user has to kill Word 2007, then they recover their document and try to save to the same document library and it saves without a problem. </p>
<p>It happens more on the training server than the live server. The live web application server rarely goes over 20% CPU (usually around 5%) and memory peaks at 2Gb of the available 4Gb (usually at 1.5Gb) so I don't think its a resources issue. </p>
<p>The document libraries are customised and deployed using Features in a Solution. The only content type in them is the standard Documents content type. </p>
<p><strong>Update</strong> We opened this with Microsoft as a support issue and it is a known issue that is targeted to be addressed in a Cumulative Update hotfix package for SharePoint in February 2009.</p>
<p><em>Edit</em> Copied the above response to an answer so this question could be flagged as answered.</p>

241,994 | <p>This is something that I have always wondered about, but never bothered to profile.</p>
<p>Is it more efficient to assign a value to a temp variable, than to keep using that value. An Example may be clearer:</p>
<pre><code>string s = reader.GetItem[0].ToString();
someClass.SomeField = s;
someOtherClass.someField = s;
</code></pre>
<p>OR</p>
<pre><code>someClass.SomeField = reader.GetItem[0].ToString();
someOtherClass.someField = reader.GetItem[0].ToString();
</code></pre>
<p>My initial thought would the top example would be more efficient as it doesn't have to access the Item collection or call ToString.</p>
<p>Would be interested to hear other peoples ideas, or definitive answer either way.</p>

242,012 | <p>After looking on MSDN, it's still unclear to me how I should form a proper predicate to use the Find() method in List using a member variable of T (where T is a class)</p>
<p>For example:</p>
<pre><code>public class Car
{
public string Make;
public string Model;
public int Year;
}
{ // somewhere in my code
List<Car> carList = new List<Car>();
// ... code to add Cars ...
Car myCar = new Car();
// Find the first of each car made between 1980 and 2000
for (int x = 1980; x < 2000; x++)
{
myCar = carList.Find(byYear(x));
Console.Writeline(myCar.Make + myCar.Model);
}
}
</code></pre>
<p>What should my "byYear" predicate look like? </p>
<p>(The MSDN example only talks about a List of dinosaurs and only searches for an unchanging value "saurus" -- It doesn't show how to pass a value into the predicate...)</p>
<p>EDIT: I'm using VS2005/.NET2.0, so I don't think Lambda notation is available to me...</p>
<p>EDIT2: Removed "1999" in the example because I may want to "Find" programatically based on different values. Example changed to range of cars from 1980 to 2000 using for-do loop.</p>

242,065 | <p>I have been enjoying learning the basics of python, but before I started reading things I tried to install various python versions and modules clumsily. Now that I have some ideas of what I want to do and how to do it I'm finding that various aspects are broken. For instance, 2.6 IDLE won't launch, and when I try to import modules they usually don't work.</p>
<p>My question is, how would you recommend I clean this up and start fresh? I have read information about modifying the 2.6 install, but I still can't get it to work.</p>
<p>IDLE 2.4 works, and when I launch python from the terminal I am running python 2.4.4.</p>

242,073 | <p>This is similar to <a href="https://stackoverflow.com/questions/18932/sql-how-can-i-remove-duplicate-rows">this question</a>, but it seems like some of the answers there aren't quite compatible with MySQL (or I'm not doing it right), and I'm having a heck of a time figuring out the changes I need. Apparently my SQL is rustier than I thought it was. I'm also looking to change a column value rather than delete, but I think at least <b>that</b> part is simple...</p>
<p>I have a table like:</p>
<pre>rowid SERIAL
fingerprint TEXT
duplicate BOOLEAN
contents TEXT
created_date DATETIME</pre>
<p>I want to set duplicate=true for all but the first (by created_date) of each group by fingerprint. It's easy to mark <em>all</em> of the rows with duplicate fingerprints as dupes. The part I'm getting stuck on is keeping the first.</p>
<p>One of the apps that populates the table does bulk loads of data, with multiple workers loading data from different sources, and the workers' data isn't necessarily partitioned by date, so it's a pain to try to mark these all as they come in (the first one inserted isn't necessarily the first one by date). Also, I already have a bunch of data in there I'll need to clean up either way. So I'd rather just have a relatively efficient query I can run after a bulk load to clean up than try to build it into that app.</p>
<p>Thanks!</p>

242,079 | <p>In Java, we can always use an array to store object reference. Then we have an ArrayList or HashTable which is automatically expandable to store objects. But does anyone know a native way to have an auto-expandable array of object references?</p>
<p>Edit: What I mean is I want to know if the Java API has some class with the ability to store references to objects (but not storing the actual object like XXXList or HashTable do) AND the ability of auto-expansion.</p>

242,118 | <p>Assuming a Perl script that allows users to specify several text filter expressions in a config file, is there a safe way to let them enter regular expressions as well, without the possibility of unintended side effects or code execution? Without actually parsing the regexes and checking them for problematic constructs, that is. There won't be any substitution, only matching.</p>
<p>As an aside, is there a way to test if the specified regex is valid before actually using it? I'd like to issue warnings if something like <code>/foo (bar/</code> was entered.</p>
<p>Thanks, Z.</p>
<p><hr>
EDIT:<br>
Thanks for the very interesting answers. I've since found out that the following dangerous constructs will only be evaluated in regexes if the <code>use re 'eval'</code> pragma is used:</p>
<pre><code>(?{code})
(??{code})
${code}
@{code}
</code></pre>
<p>The default is <code>no re 'eval'</code>; so unless I'm missing something, it should be safe to read regular expressions from a file, with the only check being the eval/catch posted by Axeman. At least I haven't been able to hide anything evil in them in my tests.</p>
<p>Thanks again. Z.</p>

<p><strong>Edit:</strong> The code here still has some bugs in it, and it could do better in the performance department, but instead of trying to fix this, for the record I took the problem over to the Intel discussion groups and got lots of great feedback, and if all goes well a polished version of Atomic float will be included in a near future release of Intel's Threading Building Blocks</p>
</blockquote>
<p>Ok here's a tough one, I want an Atomic float, not for super-fast graphics performance, but to use routinely as data-members of classes. And I don't want to pay the price of using locks on these classes, because it provides no additional benefits for my needs. </p>
<p>Now with intel's tbb and other atomic libraries I've seen, integer types are supported, but not floating points. So I went on and implemented one, and it works... but I'm not sure if it REALLY works, or I'm just very lucky that it works.</p>

<p>Thanks!</p>
<p><strong>Edit:</strong> changed size_t to uint32_t as Greg Rogers suggested, that way its more portable</p>
<p><strong>Edit:</strong> added listing for the entire thing, with some fixes.</p>
<p><strong>More Edits:</strong> Performance wise using a locked float for 5.000.000 += operations with 100 threads on my machine takes 3.6s, while my atomic float even with its silly do-while takes 0.2s to do the same work. So the >30x performance boost means its worth it, (and this is the catch) if its correct.</p>
<p><strong>Even More Edits:</strong> As Awgn pointed out my <code>fetch_and_xxxx</code> parts were all wrong. Fixed that and removed parts of the API I'm not sure about (templated memory models). And implemented other operations in terms of operator += to avoid code repetition</p>
<p><strong>Added:</strong> Added operator *= and operator /=, since floats wouldn't be floats without them. Thanks to Peterchen's comment that this was noticed</p>
<p><strong>Edit:</strong> Latest version of the code follows (I'll leave the old version for reference though)</p>

242,284 | <p>While surfing, I came to know that somebody has done Tower of Hanoi using vim. WOW!!!</p>
<p>Can you people share what all cool things you have been doing in vim.</p>
<p>Edit: Not sure about the Tower of Hanoi solution using vim being all that useful. But I think this question should be re-opened to allow people to comment on any useful things that they've done using vim. For me? See my answer below. (-:</p>

242,286 | <p>Mine would have to be the float and margin bugs...</p>
<p>If you float an element, and then specify a margin for it, it will double the margin.</p>
<p>The solution to this is to add <code>display: inline</code> to the element. This will stop the double margin, and all other browsers will ignore it because only block level objects can be floated.</p>

<p><strong>EDIT</strong>: This question duplicates <a href="https://stackoverflow.com/questions/110175/how-to-access-the-current-subversion-build-number#111173">How to access the current Subversion build number?</a> (Thanks for the heads up, Charles!)</p>
</blockquote>
<p>Hi there,</p>
<p>This question is similar to <a href="https://stackoverflow.com/questions/16248/getting-the-subversion-repository-number-into-code">Getting the subversion repository number into code</a></p>
<p>The differences being:</p>
<ol>
<li><p>I would like to add the revision number to Python</p></li>
<li><p>I want the revision of the repository (not the checked out file)</p></li>
</ol>
<p>I.e. I would like to extract the Revision number from the return from 'svn info', likeso:</p>
<p>$ svn info</p>
<pre><code>Path: .
URL: svn://localhost/B/trunk
Repository Root: svn://localhost/B
Revision: 375
Node Kind: directory
Schedule: normal
Last Changed Author: bmh
Last Changed Rev: 375
Last Changed Date: 2008-10-27 12:09:00 -0400 (Mon, 27 Oct 2008)
</code></pre>
<p>I want a variable with 375 (the Revision). It's easy enough with put $Rev$ into a variable to keep track of changes on a file. However, I would like to keep track of the repository's version, and I understand (and it seems based on my tests) that $Rev$ only updates when the file changes.</p>
<p>My initial thoughts turn to using the svn/libsvn module built in to Python, though I can't find any documentation on or examples of how to use them.</p>
<p>Alternatively, I've thought calling 'svn info' and regex'ing the code out, though that seems rather brutal. :)</p>
<p>Help would be most appreciated.</p>
<p>Thanks & Cheers.</p>

242,314 | <p>Using gnuplot 4.2, is it possible to obtain the value of a specific column/row and use that value somehow?</p>
<p>For example, let's say my datafile contains the following</p>
<pre><code>#1 2
7 13
5 11
23 17
53 12
</code></pre>
<p>For a simple plot where column 1 is the x axis and column 2 is the y axis I would:-</p>
<pre><code>plot 'datafile' using 1:2
</code></pre>
<p>What I'm trying to do is to normalize the all data in column 2 by the first element in that column (13). Is there a way to do this in gnuplot itself (i.e., without resorting to a scripting language or something to preprocess the data first)?</p>
<p>Cheers</p>

242,438 | <p>I've a performance related question regarding use of StringBuilder.
In a very long loop I'm manipulating a <code>StringBuilder</code> and passing it to another method like this:</p>
<pre><code>for (loop condition) {
StringBuilder sb = new StringBuilder();
sb.append("some string");
. . .
sb.append(anotherString);
. . .
passToMethod(sb.toString());
}
</code></pre>
<p>Is instantiating <code>StringBuilder</code> at every loop cycle is a good solution? And is calling a delete instead better, like the following?</p>
<pre><code>StringBuilder sb = new StringBuilder();
for (loop condition) {
sb.delete(0, sb.length);
sb.append("some string");
. . .
sb.append(anotherString);
. . .
passToMethod(sb.toString());
}

</connectionStrings>
</code></pre>
<p>Yet, when I retrieve this value using <code>ConfigurationManager.ConnectionStringsp["HRDb"]</code>, I get the my old connection string, not the new one.</p>
<p>Where else (apart from web.config) does the <code>ConfigurationManager</code> read connection string values from?</p>
<p>I'm running the application from VS.NET (not deployed to IIS).</p>

242,485 | <p>This is a question I have wondered about for quite some time, yet I have never found a suitable solution. If I run a script and I come across, let's say an IndexError, python prints the line, location and quick description of the error and exits. Is it possible to automatically start pdb when an error is encountered? I am not against having an extra import statement at the top of the file, nor a few extra lines of code.</p>

242,504 | <p>How can I generate a report in access with the data from a recordset (instead of a query or table). I have updates to the recordset that also must be shown in the report.</p>

242,517 | <p>I have a certain application which feeds information into an object, after comparing the new information to the old information.
It goes something like</p>
<pre><code>set
{
oldval=_value;
_value=value;
if (some comparison logic)
raiseEvent();
}
</code></pre>
<p>This all happens on a background thread, in an infinite loop, which intermittently sleeps for 100ms.
The really odd part is that it works the first time, the comparison logic turns up true, and the event is raised.
After that, the information keeps flowing, it keep entering the object, I know this because I set MessageBoxes to display the old and new values all the time, but its as if it somehow bypasses the set clause!
I set a messagebox in the beginning of the clause, an it just doesn't pop up!
This is really wierd, since I am sure that the value keeps updating.</p>
<p>Any Thoughts?</p>
<hr>
<p>Yeah, I know, but unfortunately theres not much more I can show...
Let me try to explain the overall structure again:
I have a separate background thread running an infinite loop.
This loop continuously pulls data from a Data object, which is updated by a whole other set of threads.
All of this is of course under synchronization with Monitor.Enter and Exit.
The data pulled from the Data object is then inputted into the Comparer object.</p>
<pre><code>while(true)
{
Thread.Sleep(100);
Monitor.Enter(Data);
Comparer.Value = Data.Value;
Monitor.Exit(Data);
}
</code></pre>
<p>The Comparer.Value is the property I mentioned in the first post.
Its really quite weird since I set up a MessageBox in the end of the loop:</p>
<pre><code>MessageBox.Show(Comparer.Value + " - " + Data.Value);
</code></pre>
<p>and the values DO actually update, it just somehow seems to bypass the set clause, which is impossible...
This is truly weird.</p>
<p>And Rob, the loop doesn't do any of the checking, it just simulates a stream of information into Comparer.Value; It's set clause contains the comparison logic.</p>
<p>bh213, I'm pretty that it is, but I can't tell because the comparison stops before any meaningful checking is done.</p>
<hr>
<p>Alright, I've solved the problem, apparently my question was wrong, the problem was in a whole other place.
Thanks for all the help, the question may be closed.</p>

<p>or</p>
<pre><code>private const int theAnswer = 42;

<p>Personally I think with modern IDEs we should go with camelCase as ALL_CAPS looks strange. What do you think?</p>
