53,428 | <p>I'm evaluating and looking at using CherryPy for a project that's basically a JavaScript front-end from the client-side (browser) that talks to a Python web service on the back-end. So, I really need something fast and lightweight on the back-end that I can implement using Python that then speaks to the PostgreSQL DB via an ORM (JSON to the browser).</p>
<p>I'm also looking at Django, which I like, since its ORM is built-in. However, I think Django might be a little more than I really need (i.e. more features than I really need == slower?).</p>
<p>Anyone have any experience with different Python ORM solutions that can compare and contrast their features and functionality, speed, efficiency, etc.?</p>

53,435 | <p>I'm doing something bad in my ASP.NET app. It could be the any number of CTP libraries I'm using or I'm just not disposing something properly. But when I redeploy my ASP.NET to my Vista IIS7 install or my server's IIS6 install I crash an IIS worker process.</p>
<p>I've narrowed the problem down to my HTTP crawler, which is a multithreaded beast that crawls sites for useful information when asked to. After I start a crawler and redeploy the app over the top, rather than gracefully unloading the appDomain and reloading, an IIS worker process will crash (popping up a crash message) and continue reloading the app domain.</p>
<p>When this crash happens, where can I find the crash dump for analysis?</p>

53,472 | <p>I have some Ruby code which takes dates on the command line in the format:</p>
<pre><code>-d 20080101,20080201..20080229,20080301
</code></pre>
<p>I want to run for all dates between <code>20080201</code> and <code>20080229</code> inclusive and the other dates present in the list.</p>
<p>I can get the string <code>20080201..20080229</code>, so is the best way to convert this to a Range instance? Currently, I am using <code>eval</code>, but it feels like there should be a better way.</p>

<p>I want to apply a <code>class="h30"</code> to that paragraph so that I can style it in my style sheet. I can't find any information on getting the value of an attribute that is not an <code>id</code> or <code>class</code>. Help?</p>

53,480 | <p>Hey, I'm using <a href="http://en.wikipedia.org/wiki/Levenshtein_distance" rel="nofollow noreferrer">Levenshteins</a> algorithm to get distance between source and target string.</p>
<p>also I have method which returns value from 0 to 1:</p>
<pre><code>/// <summary>
/// Gets the similarity between two strings.
/// All relation scores are in the [0, 1] range,
/// which means that if the score gets a maximum value (equal to 1)
/// then the two string are absolutely similar
/// </summary>
/// <param name="string1">The string1.</param>
/// <param name="string2">The string2.</param>
/// <returns></returns>
public static float CalculateSimilarity(String s1, String s2)
{
if ((s1 == null) || (s2 == null)) return 0.0f;
float dis = LevenshteinDistance.Compute(s1, s2);
float maxLen = s1.Length;
if (maxLen < s2.Length)
maxLen = s2.Length;
if (maxLen == 0.0F)
return 1.0F;
else return 1.0F - dis / maxLen;
}
</code></pre>
<p>but this for me is not enough. Because I need more complex way to match two sentences.</p>
<p>For example I want automatically tag some music, I have original song names, and i have songs with trash, like <em>super, quality,</em> years like <em>2007, 2008,</em> etc..etc.. also some files have just <a href="http://trash..thash..song_name_mp3.mp3" rel="nofollow noreferrer">http://trash..thash..song_name_mp3.mp3</a>, other are normal. I want to create an algorithm which will work just more perfect than mine now.. Maybe anyone can help me?</p>
<p>here is my current algo:</p>
<pre><code>/// <summary>
/// if we need to ignore this target.
/// </summary>
/// <param name="targetString">The target string.</param>
/// <returns></returns>
private bool doIgnore(String targetString)
{
if ((targetString != null) && (targetString != String.Empty))
{
for (int i = 0; i < ignoreWordsList.Length; ++i)
{
//* if we found ignore word or target string matching some some special cases like years (Regex).
if (targetString == ignoreWordsList[i] || (isMatchInSpecialCases(targetString))) return true;
}
}
return false;
}
/// <summary>
/// Removes the duplicates.
/// </summary>
/// <param name="list">The list.</param>

{

{
for (int i = 0; i < list.Count - 1; ++i)
{
if (list[i] == list[i + 1])
{
list.RemoveAt(i);
--i;
}
}
}
}
/// <summary>
/// Does the fuzzy match.
/// </summary>
/// <param name="targetTitle">The target title.</param>
/// <returns></returns>
private TitleMatchResult doFuzzyMatch(String targetTitle)
{
TitleMatchResult matchResult = null;
if (targetTitle != null && targetTitle != String.Empty)
{
try
{
//* change target title (string) to lower case.
targetTitle = targetTitle.ToLower();
//* scores, we will select higher score at the end.
Dictionary<Title, float> scores = new Dictionary<Title, float>();
//* do split special chars: '-', ' ', '.', ',', '?', '/', ':', ';', '%', '(', ')', '#', '\"', '\'', '!', '|', '^', '*', '[', ']', '{', '}', '=', '!', '+', '_'
List<String> targetKeywords = new List<string>(targetTitle.Split(ignoreCharsList, StringSplitOptions.RemoveEmptyEntries));
//* remove all trash from keywords, like super, quality, etc..
targetKeywords.RemoveAll(delegate(String x) { return doIgnore(x); });
//* sort keywords.
targetKeywords.Sort();
//* remove some duplicates.
removeDuplicates(targetKeywords);
//* go through all original titles.
foreach (Title sourceTitle in titles)
{
float tempScore = 0f;
//* split orig. title to keywords list.
List<String> sourceKeywords = new List<string>(sourceTitle.Name.Split(ignoreCharsList, StringSplitOptions.RemoveEmptyEntries));
sourceKeywords.Sort();
removeDuplicates(sourceKeywords);
//* go through all source ttl keywords.
foreach (String keyw1 in sourceKeywords)
{
float max = float.MinValue;
foreach (String keyw2 in targetKeywords)
{
float currentScore = StringMatching.StringMatching.CalculateSimilarity(keyw1.ToLower(), keyw2);
if (currentScore > max)
{
max = currentScore;
}
}
tempScore += max;
}
//* calculate average score.
float averageScore = (tempScore / Math.Max(targetKeywords.Count, sourceKeywords.Count));
//* if average score is bigger than minimal score and target title is not in this source title ignore list.
if (averageScore >= minimalScore && !sourceTitle.doIgnore(targetTitle))
{
//* add score.
scores.Add(sourceTitle, averageScore);
}
}
//* choose biggest score.
float maxi = float.MinValue;
foreach (KeyValuePair<Title, float> kvp in scores)
{
if (kvp.Value > maxi)
{
maxi = kvp.Value;
matchResult = new TitleMatchResult(maxi, kvp.Key, MatchTechnique.FuzzyLogic);
}
}
}
catch { }
}
//* return result.
return matchResult;
}
</code></pre>
<p>This works normally but just in some cases, a lot of titles which should match, does not match... I think I need some kind of formula to play with weights and etc, but i can't think of one.. </p>
<p>Ideas? Suggestions? Algos?</p>
<p>by the way I already know this topic (My colleague already posted it but we cannot come with a proper solution for this problem.):

53,538 | <p>Is it possible to order results in SQL Server 2005 by the relevance of a freetext match? In MySQL you can use the (roughly equivalent) MATCH function in the ORDER BY section, but I haven't found any equivalence in SQL Server.</p>
<p>From the <a href="http://dev.mysql.com/doc/refman/5.0/en/fulltext-natural-language.html" rel="noreferrer">MySQL docs</a>:</p>
<blockquote>
<p>For each row in the table, MATCH() returns a relevance value; that is, a similarity measure between the search string and the text in that row in the columns named in the MATCH() list.</p>
</blockquote>
<p>So for example you could order by the number of votes, then this relevance, and finally by a creation date. Is this something that can be done, or am I stuck with just returning the matching values and not having this ordering ability?</p>

53,562 | <p>What are the steps required to enable Hibernate's second-level cache, when using the Java Persistence API (annotated entities)? How do I check that it's working? I'm using JBoss 4.2.2.GA.</p>
<p>From the Hibernate documentation, it seems that I need to enable the cache and specify a cache provider in <em>persistence.xml</em>, like:</p>
<pre><code><property name="hibernate.cache.use_second_level_cache"
value="true" />
<property name="hibernate.cache.provider_class"
value="org.hibernate.cache.HashtableCacheProvider" />
</code></pre>
<p>What else is required? Do I need to add <em>@Cache</em> annotations to my JPA entities?</p>
<p>How can I tell if the cache is working? I have tried accessing cache statistics after running a Query, but <em>Statistics.getSecondLevelCacheStatistics</em> returns null, perhaps because I don't know what 'region' name to use.</p>

53,569 | <p>What is the best way to get a log of commits on a branch since the time it was branched from the current branch? My solution so far is:</p>
<pre><code>git log $(git merge-base HEAD branch)..branch
</code></pre>
<p>The documentation for <a href="http://git-scm.com/docs/git-diff" rel="noreferrer">git-diff</a> indicates that <code>git diff A...B</code> is equivalent to <code>git diff $(git-merge-base A B) B</code>. On the other hand, the documentation for <a href="http://www.kernel.org/pub/software/scm/git/docs/git-rev-parse.html" rel="noreferrer">git-rev-parse</a> indicates that <code>r1...r2</code> is defined as <code>r1 r2 --not $(git merge-base --all r1 r2)</code>.</p>
<p>Why are these different? Note that <code>git diff HEAD...branch</code> gives me the diffs I want, but the corresponding git log command gives me more than what I want.</p>
<p>In pictures, suppose this:</p>
<pre>
x---y---z---branch
/
---a---b---c---d---e---HEAD
</pre>
<p>I would like to get a log containing commits x, y, z.</p>
<ul>
<li><code>git diff HEAD...branch</code> gives these commits</li>
<li>however, <code>git log HEAD...branch</code> gives x, y, z, c, d, e.</li>

53,609 | <p>I hope this qualifies as a programming question, as in any programming tutorial, you eventually come across 'foo' in the code examples. (yeah, right?)</p>
<p>what does 'foo' really mean?</p>
<p>If it is meant to mean <strong>nothing</strong>, when did it begin to be used so?</p>

53,652 | <p>This might be a bit on the silly side of things but I need to send the contents of a DataTable (unknown columns, unknown contents) via a text e-mail. Basic idea is to loop over rows and columns and output all cell contents into a StringBuilder using .ToString(). </p>
<p>Formatting is a big issue though. Any tips/ideas on how to make this look "readable" in a text format ? </p>
<p>I'm thinking on "padding" each cell with empty spaces, but I also need to split some cells into multiple lines, and this makes the StringBuilder approach a bit messy ( because the second line of text from the first column comes after the first line of text in the last column,etc.)</p>

53,664 | <p>I've started using Vim to develop Perl scripts and am starting to find it very powerful. </p>
<p>One thing I like is to be able to open multiple files at once with:</p>
<pre><code>vi main.pl maintenance.pl
</code></pre>
<p>and then hop between them with:</p>
<pre><code>:n
:prev
</code></pre>
<p>and see which file are open with:</p>
<pre><code>:args
</code></pre>
<p>And to add a file, I can say: </p>
<pre><code>:n test.pl
</code></pre>
<p>which I expect would then be added to my list of files, but instead it wipes out my current file list and when I type <code>:args</code> I only have <code>test.pl</code> open.</p>
<p>So how can I add and remove files in my args list?</p>

53,715 | <p>Does Delphi call inherited on overridden procedures if there is no explicit call in the code ie (inherited;), I have the following structure (from super to sub class)</p>
<p>TForm >> TBaseForm >> TAnyOtherForm</p>
<p>All the forms in the project will be derived from TBaseForm, as this will have all the standard set-up and destructive parts that are used for every form (security, validation ect). </p>
<p>TBaseForm has onCreate and onDestroy procedures with the code to do this, but if someone (ie me) forgot to add inherited to the onCreate on TAnyOtherForm would Delphi call it for me? I have found references on the web that say it is not required, but nowhere says if it gets called if it is omitted from the code.</p>
<p>Also if it does call inherited for me, when will it call it?</p>

53,734 | <p>If you're creating a temporary table within a stored procedure and want to add an index or two on it, to improve the performance of any additional statements made against it, what is the best approach? Sybase says <a href="http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.dc20020_1251/html/databases/databases644.htm" rel="noreferrer">this</a>:</p>
<p><em>"the table must contain data when the index is created. If you create the temporary table and create the index on an empty table, Adaptive Server does not create column statistics such as histograms and densities. If you insert data rows after creating the index, the optimizer has incomplete statistics."</em></p>
<p>but recently a colleague mentioned that if I create the temp table and indices in a different stored procedure to the one which actually uses the temporary table, then Adaptive Server optimiser <em>will</em> be able to make use of them.</p>
<p>On the whole, I'm not a big fan of wrapper procedures that add little value, so I've not actually got around to testing this, but I thought I'd put the question out there, to see if anyone had any other approaches or advice?</p>

53,786 | <p>I am trying to automate functional testing of a server using a realistic frequency distribution of requests. (sort of load testing, sort of simulation)</p>
<p>I've chosen the <a href="http://en.wikipedia.org/wiki/Weibull_distribution" rel="nofollow noreferrer">Weibull</a> distribution as it "sort of" matches the distribution I've observed (ramps up quickly, drops off quickly but not instantly)</p>
<p>I use this distribution to generate the number of requests that should be sent each day between a given start and end date</p>
<p>I've hacked together an algorithm in Python that sort of works but it feels kludgy:</p>
<pre><code>how_many_days = (end_date - start_date).days
freqs = defaultdict(int)
for x in xrange(how_many_responses):
freqs[int(how_many_days * weibullvariate(0.5, 2))] += 1
timeline = []
day = start_date
for i,freq in sorted(freqs.iteritems()):
timeline.append((day, freq))
day += timedelta(days=1)
return timeline

53,803 | <p>We're looking at moving from a check-out/edit/check-in style of version control system to Subversion, and during the evaluation we discovered that when you perform an Update action in TortoiseSVN (and presumably in any Subversion client?), if changes in the repository that need to be applied to files that you've been editing don't cause any conflicts then they'll be automatically/silently merged.</p>
<p>This scares us a little, as it's possible that this merge, while not producing any compile errors, could at least introduce some logic errors that may not be easily detected.</p>
<p>Very simple example: I'm working within a C# method changing some logic in the latter-part of the method, and somebody else changes the value that a variable gets initialised to at the start of the method. The other person's change isn't in the lines of code that I'm working on so there won't be a conflict; but it's possible to dramatically change the output of the method.</p>
<p>What we were hoping the situation would be is that if a merge needs to occur, then the two files would be shown and at least a simple accept/reject change option be presented, so that at least we're aware that something has changed and are given the option to see if it impacts our code.</p>
<p>Is there a way to do this with Subversion/TortoiseSVN? Or are we stuck in our present working ways too much and should just let it do it's thing...</p>

53,811 | <p>Do you normally set your compiler to optimize for maximum speed or smallest code size? or do you manually configure individual optimization settings? Why?</p>
<p>I notice most of the time people tend to just leave compiler optimization settings to their default state, which with visual c++ means max speed.
I've always felt that the default settings had more to do with looking good on benchmarks, which tend to be small programs that will fit entirely within the L2 cache than what's best for overall performance, so I normally set it optimize for smallest size.</p>

53,827 | <p>I'm using MinGW with GCC 3.4.5 (mingw-special vista r3).</p>
<p>My C application uses a lot of stack so I was wondering is there any way I can tell programatically how much stack is remaining so I can cleanly handle the situation if I find that I'm about to run out.</p>
<p>If not what other ways would you work around the problem of potentially running out of stack space?</p>
<p>I've no idea what size of stack I'll start with so would need to identify that programatically also.</p>

53,945 | <p>I am currently loading a lightbox style popup that loads it's HTML from an XHR call. This content is then displayed in a 'modal' popup using <code>element.innerHTML = content</code> This works like a charm.</p>
<p>In another section of this website I use a Flickr 'badge' (<a href="http://www.elliotswan.com/2006/08/06/custom-flickr-badge-api-documentation/" rel="noreferrer">http://www.elliotswan.com/2006/08/06/custom-flickr-badge-api-documentation/</a>) to load flickr images dynamically. This is done including a script tag that loads a flickr javascript, which in turn does some <code>document.write</code> statments.</p>
<p>Both of them work perfectly when included in the HTML. Only when loading the flickr badge code <em>inside</em> the lightbox, no content is rendered at all. It seems that using <code>innerHTML</code> to write <code>document.write</code> statements is taking it a step too far, but I cannot find any clue in the javascript implementations (FF2&3, IE6&7) of this behavior.</p>
<p>Can anyone clarify if this should or shouldn't work? Thanks.</p>

53,961 | <p>I'm working with a large (270+ project) VS.Net solution. Yes, I know this is pushing the friendship with VS but it's inherited and blah blah. Anyway, to speed up the solution load and compile time I've removed all projects that I'm not currently working on... which in turn has removed those project references from the projects I want to retain. So now I'm going through a mind numbing process of adding binary references to the retained projects so that the referenced Types can be found.</p>
<p>Here's how I'm working at present;</p>
<ul>
<li>Attempt to compile, get thousands of
errors, 'type or namespace missing'</li>
<li>Copy the first line of the error
list to the clipboard</li>
<li>Using a perl script hooked up to a
hotkey (AHK) I extract the type name from
the error message and store it in the windows clipboard</li>
<li>I paste the type name into source
insight symbol browser and note the
assembly containing the Type</li>
<li>I go back to VS and add that
assembly as a binary reference to
the relevant project</li>
</ul>
<p>So now, after about 30 mins I'm thinking there's just got to be a quicker way...</p>

53,989 | <p>Usually Flash and Flex applications are embedded on in HTML using either a combination of <code>object</code> and <code>embed</code> tags, or more commonly using JavaScript. However, if you link directly to a SWF file it will open in the browser window and without looking in the address bar you can't tell that it wasn't embedded in HTML with the size set to 100% width and height.</p>
<p>Considering the overhead of the HTML, CSS and JavaScript needed to embed a Flash or Flex application filling 100% of the browser window, what are the downsides of linking directly to the SWF file instead? What are the upsides?</p>
<p>I can think of one upside and three downsides: you don't need the 100+ lines of HTML, JavaScript and CSS that are otherwise required, but you have no plugin detection, no version checking and you lose your best SEO option (progressive enhancement).</p>
<p><em>Update</em> don't get hung up on the 100+ lines, I simply mean that the the amount of code needed to embed a SWF is quite a lot (and I mean including libraries like SWFObject), and it's just for displaying the SWF, which can be done without a single line by linking to it directly.</p>

54,096 | <p>I got a little curious after reading <a href="http://it.slashdot.org/it/08/09/09/1558218.shtml" rel="noreferrer">this /. article</a> over hijacking HTTPS cookies. I tracked it down a bit, and a good resource I stumbled across lists a few ways to secure cookies <a href="http://casabasecurity.com/content/using-aspnet-session-handling-secure-sites-set-secure-flag" rel="noreferrer">here</a>. Must I use adsutil, or will setting requireSSL in the httpCookies section of web.config cover session cookies in addition to all others (<a href="http://msdn2.microsoft.com/en-us/library/ms228262.aspx" rel="noreferrer">covered here</a>)? Is there anything else I should be considering to harden sessions further?</p>

54,138 | <p>I have a third-party app that creates HTML-based reports that I need to display. I have <em>some</em> control over how they look, but in general it's pretty primitive. I <em>can</em> inject some javascript, though. I'd like to try to inject some jQuery goodness into it to tidy it up some. One specific thing I would like to do is to take a table (an actual HTML <table>) that always contains one row and a variable number of columns and magically convert that into a tabbed view where the contents (always one <div> that I can supply an ID if necessary) of each original table cell represents a sheet in the tabbed view. I haven't found any good (read: simple) examples of re-parenting items like this, so I'm not sure where to begin. Can someone provide some hints on how I might try this?</p>

54,142 | <p>How does the comma operator work in C++?</p>
<p>For instance, if I do:</p>
<pre><code>a = b, c;
</code></pre>
<p>Does a end up equaling b or c? </p>
<p>(Yes, I know this is easy to test - just documenting on here for someone to find the answer quickly.)</p>
<p><strong>Update:</strong> This question has exposed a nuance when using the comma operator. Just to document this:</p>
<pre><code>a = b, c; // a is set to the value of b!
a = (b, c); // a is set to the value of c!
</code></pre>
<p>This question was actually inspired by a typo in code. What was intended to be</p>
<pre><code>a = b;
c = d;
</code></pre>
<p>Turned into</p>
<pre><code>a = b, // <- Note comma typo!
c = d;
</code></pre>

54,188 | <p>I have two threads, one updating an int and one reading it. This is a statistic value where the order of the reads and writes is irrelevant.</p>
<p>My question is, do I need to synchronize access to this multi-byte value anyway? Or, put another way, can part of the write be complete and get interrupted, and then the read happen.</p>
<p>For example, think of a value = 0x0000FFFF that gets incremented value of 0x00010000.</p>
<p>Is there a time where the value looks like 0x0001FFFF that I should be worried about? Certainly the larger the type, the more possible something like this to happen.</p>
<p>I've always synchronized these types of accesses, but was curious what the community thinks.</p>

<p>I know the .Net framework will not allow a web.config file to be served, however I still think its bad practice to leave this sort of information in plain text. </p>
<p>Everything I have read so far requires me to use a command line switch or to store values in the registry of the server. I have access to neither of these as the host is online and I have only FTP and Control Panel (helm) access.</p>
<p>Can anyone recommend any good, free encryption DLL's or methods which I can use? I'd rather not develop my own!</p>
<p>Thanks for the feedback so far guys but I am not able to issue commands and and not able to edit the registry. Its going to have to be an encryption util/helper but just wondering which one!</p>

54,207 | <p>I have an internal enterprise app that currently consumes 10 different web services. They're consumed via old style "Web References" instead of using WCF.</p>
<p>The problem I'm having is trying to work with the other teams in the company who are authoring the services I'm consuming. I found I needed to capture the exact SOAP messages that I'm sending and receiving. I did this by creating a new attribute that extends SoapExtensionAttribute. I then just add that attribute to the service method in the generated Reference.cs file. This works, but is painful for two reasons. First, it's a generated file so anything I do in there can be overwritten. Second, I have to remember to remove the attribute before checking in the file.</p>
<p><strong>Is There a better way to capture the exact SOAP messages that I am sending and receiving?</strong></p>

54,219 | <p>I'm working on an editor for files that are used by an important internal testing tool we use. The tool itself is large, complicated, and refactoring or rewriting would take more resources than we are able to devote to it for the forseeable future, so my hands are tied when it comes to large modifications. I must use a .NET language.</p>
<p>The files are XML serialized versions of four classes that are used by the tool (let's call them A, B, C, and D). The classes form a tree structure when all is well. Our editor works by loading a set of files, deserializing them, working out the relationships between them, and keeping track of any bad states it can find. The idea is for us to move away from hand-editing these files, which introduces tons of errors.</p>
<p>For a particular type of error, I'd like to maintain a collection of all files that have the problem. All four classes can have the problem, and I'd like to reduce duplication of code as much as possible. An important requirement is the user needs to be able to get the items in sets; for example, they need to get all A objects with an error, and telling them to iterate over the whole collection and pick out what they want is unacceptable compared to a <code>GetAs()</code> method. So, my first thought was to make a generic item that related the deserialized object and some metadata to indicate the error:</p>
<pre><code>public class ErrorItem<T>
{
public T Item { get; set; }
public Metadata Metadata { get; set; }
}
</code></pre>
<p>Then, I'd have a collection class that could hold all of the error items, with helper methods to extract the items of a specific class when the user needs them. This is where the trouble starts.</p>
<p>None of the classes inherit from a common ancestor (other than <code>Object</code>). This was probably a mistake of the initial design, but I've spent a few days thinking about it and the classes really don't have much in common other than a GUID property that uniquely identifies each item so I can see why the original designer did not relate them through inheritance. This means that the unified error collection would need to store <code>ErrorItem<Object></code> objects, since I don't have a base class or interface to restrict what comes in. However, this makes the idea of this unified collection a little sketchy to me:</p>
<pre><code>Public Class ErrorCollection
{
public ErrorItem<Object> AllItems { get; set; }
}
</code></pre>
<p>However, this has consequences on the public interface. What I really want is to return the appropriate <code>ErrorItem</code> generic type like this:</p>
<pre><code>public ErrorItem<A>[] GetA()
</code></pre>
<p>This is impossible because I can only store <code>ErrorItem<Object></code>! I've gone over some workarounds in my head; mostly they include creating a new <code>ErrorItem</code> of the appropriate type on-the-fly, but it just feels kind of ugly. Another thought has been using a <code>Dictionary</code> to keep items organized by type, but it still doesn't seem right.</p>
<p>Is there some kind of pattern that might help me here? I know the easiest way to solve this is to add a base class that A, B, C, and D derive from, but I'm trying to have as small an impact on the original tool as possible. Is the cost of any workaround great enough that I should push to change the initial tool?</p>

54,237 | <p>I want to link to bookmark on a page (mysite.com/mypage.htm#bookmark) AND visually highlight the item that was bookmarked (maybe having a red border). Naturally, there would be multiple items bookmarked. So that if someone clicked on #bookmark2 then <em>that</em> other area would be highlighted). </p>
<p>I can see how to do that with .asp or .aspx but I'd like to do it more simply than that. I thought maybe there was a clever way to do it with CSS.</p>
<p>WHY I'm interested:
- I want to have our programs link to a shopping page that lists all the programs on it. I'm using a bookmark so they're jumping to the particular program area (site.com/shoppingpage#Programx) but just to make it <em>obvious</em> I'd like to actually highlight the page being linked to.</p>

54,255 | <p>Using Vim I often want to replace a block of code with a block that I just yanked.</p>
<p>But when I delete the block of code that is to be replaced, that block itself goes into the register which erases the block I just yanked. So I've got in the habit of yanking, then inserting, then deleting what I didn't want, but with large blocks of code this gets messy trying to keep the inserted block and the block to delete separate.</p>
<p>So what is the slickest and quickest way to replace text in Vim?</p>
<ul>
<li>is there a way to delete text without putting it into the register?</li>
<li>is there a way to say e.g. "replace next word" or "replace up to next paragraph"</li>
<li>or is the best way to somehow use the multi-register feature?</li>
</ul>

<p>One tool I know of is <a href="http://www.statsvn.org/" rel="noreferrer">statsvn</a> - a Java tool that creates some HTML reports and some code churn metrics. Statsvn reports the number of lines modified (churned) by user over time, some descriptive stats on LOC per file and folder/subfolder, etc.</p>
<p>I would like to know code churn in order to get a better idea of the state of the project. Idea behind this inspired by the MS research: <a href="http://research.microsoft.com/research/pubs/view.aspx?type=Publication&id=1359" rel="noreferrer">Use of Relative Code Churn Measures to Predict System Defect Density</a></p>
<p>In a nutshell, the more that source code is churning (changing, whether adding new lines, deleting, changing,etc) the higher the probability that defects are being introduced into the system. The MS research paper says that the number of defects produced can be predicted based on a number of relative code churn measures.</p>
<p>I wanted to know if there are any others that are maybe open source, extensible, etc.</p>

<p>but that just seems kind of primitive. Googling around I find vim macros mentioned and something about "maps" but nothing that seems straightforward.</p>
<p>What I am looking for are e.g. something like Eclipse's "Templates" so I pop in a code chunk with the cursor sitting in the middle of it.
Or JEdit's "Macros" which I can record doing complicated deletes and renaming on one line, then I can play it again on 10 other lines so it does the same to them.</p>
<p>Does vim have anything like these two functionalities?</p>

54,418 | <p>I need to retrieve all rows from a table where 2 columns combined are all different. So I want all the sales that do not have any other sales that happened on the same day for the same price. The sales that are unique based on day and price will get updated to an active status.</p>
<p>So I'm thinking:</p>
<pre><code>UPDATE sales
SET status = 'ACTIVE'
WHERE id IN (SELECT DISTINCT (saleprice, saledate), id, count(id)
FROM sales
HAVING count = 1)
</code></pre>
<p>But my brain hurts going any farther than that.</p>

54,419 | <p>I have a WCF application that has two Services that I am trying to host in a single Windows Service using net.tcp. I can run either of the services just fine, but as soon as I try to put them both in the Windows Service only the first one loads up. I have determined that the second services ctor is being called but the OnStart never fires. This tells me that WCF is finding something wrong with loading up that second service.</p>
<p>Using net.tcp I know I need to turn on port sharing and start the port sharing service on the server. This all seems to be working properly. I have tried putting the services on different tcp ports and still no success.</p>
<p>My service installer class looks like this:</p>
<pre><code> [RunInstaller(true)]
public class ProjectInstaller : Installer
{
private ServiceProcessInstaller _process;
private ServiceInstaller _serviceAdmin;
private ServiceInstaller _servicePrint;
public ProjectInstaller()
{
_process = new ServiceProcessInstaller();
_process.Account = ServiceAccount.LocalSystem;
_servicePrint = new ServiceInstaller();
_servicePrint.ServiceName = "PrintingService";
_servicePrint.StartType = ServiceStartMode.Automatic;
_serviceAdmin = new ServiceInstaller();
_serviceAdmin.ServiceName = "PrintingAdminService";
_serviceAdmin.StartType = ServiceStartMode.Automatic;
Installers.AddRange(new Installer[] { _process, _servicePrint, _serviceAdmin });
}
}
</code></pre>
<p>and both services looking very similar</p>
<pre><code> class PrintService : ServiceBase
{
public ServiceHost _host = null;
public PrintService()
{
ServiceName = "PCTSPrintingService";
CanStop = true;
AutoLog = true;
}
protected override void OnStart(string[] args)
{
if (_host != null) _host.Close();
_host = new ServiceHost(typeof(Printing.ServiceImplementation.PrintingService));
_host.Faulted += host_Faulted;
_host.Open();
}
}

54,421 | <p>If you are writing a program that is executable from the command line, you often want to offer the user several options or flags, along with possibly more than one argument. I have stumbled my way through this many times, but is there some sort of design pattern for looping through args and calling the appropriate handler functions?</p>
<p>Consider:</p>
<pre><code>myprogram -f filename -d directory -r regex
</code></pre>
<p>How do you organize the handler functions after you retrieve the arguments using whatever built-ins for your language? (language-specific answers welcomed, if that helps you articulate an answer)</p>

54,475 | <p>I've run into a problem where I make changes to a few JavaScript files that are referenced in an HTML file, but the browser doesn't see the changes. It holds onto the copy cached in the browser, even though the web server has a newer version.</p>
<p>Not until I force the browser to clear the cache do I see the changes.</p>
<p>Is this a web-server configuration? Do I need to set my JavaScript files to never cache? I've seen some interesting techniques in the <a href="http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=FAQ_GWTApplicationFiles" rel="noreferrer">Google Web Toolkit</a> where they actually create a <strong>new</strong> JavaScript file name any time an update is made. I believe this is to prevent proxies and browsers from keeping old versions of the JavaScript files with the same names.</p>
<p>Is there a list of best practices somewhere?</p>

54,500 | <p>Alright, so I'm working on an application which will use a Linux back-end running PostgreSQL to serve up images to a Windows box with the front end written in C#.NET, though the front-end should hardly matter. My question is:</p>
<ul>
<li><strong>What is the best way to deal with storing images in Postgres?</strong></li>
</ul>
<p>The images are around 4-6 megapixels each, and we're storing upwards of 3000. It might also be good to note: this is not a web application, there will at most be about two front-ends accessing the database at once.</p>

54,503 | <p>I'm working on a .net post-commit hook to feed data into OnTime via their Soap SDK. My hook works on Windows fine, but on our production RHEL4 subversion server, it won't work when called from a shell script.</p>

<p>Any ideas why it might be failing from a shell script or what might be wrong with the bundled version?</p>
<p><b>Edit:</b> <a href="https://stackoverflow.com/questions/54503/problem-with-net-app-under-linux-doesnt-work-from-shell-script#54537">@Herms</a>, I've already tried it with an echo, and it looks right. As for the <code>$1/hooks/post-commit.exe</code>, I've tried the script with and without a full path to the .net assembly with the same results.</p>
<p><b>Edit:</b> <a href="https://stackoverflow.com/questions/54503/problem-with-net-app-under-linux-doesnt-work-from-shell-script#54545">@Leon</a>, I've tried both <code>$1 $2</code> and <code>"$@"</code> with the same results. It is a subversion post commit hook, and it takes two parameters, so those need to be passed along to the .net assembly. The <code>"$@"</code> was what was recommended at the mono site for calling a .net assembly from a shell script. The shell script <i>is</i> executing the .net assembly and with the correct parameters, but it is throwing an exception that does not get thrown when run directly from the command line.</p>
<p><b>Edit:</b> <a href="https://stackoverflow.com/questions/54503/problem-with-net-app-under-linux-doesnt-work-from-shell-script#54568">@Vinko</a>, I don't see any differences in the environment other than things like <code>BASH_LINENO</code> and <code>BASH_SOURCE</code></p>
<p><b>Edit:</b> <a href="https://stackoverflow.com/questions/54503/problem-with-net-app-under-linux-doesnt-work-from-shell-script#54818">@Luke</a>, I tired it, but that makes no difference either. I first noticed the problem when testing from TortoiseSVN on my machine (when it runs as a sub-process of the subversion daemon), but also found that I get the same results when executing the script from the hooks directory (i.e. <code>./post-commit REPOS REV</code>, where <code>post-commit</code> is the above sh script. Doing <code>mono post-commit.exe REPOS REV</code> works fine. The main problem is that to execute, I need to have something of the name <code>post-commit</code> so that it will be called. But it does not work from a shell script, and as noted above, the <code>mkbundle</code> is not working with a different problem.</p>

54,536 | <p>How do I create a windows application that does the following:</p>
<ul>
<li>it's a regular GUI app when invoked with no command line arguments</li>
<li>specifying the optional "--help" command line argument causes the app to write usage text to stdout then terminate</li>
<li>it must be a single executable. No cheating by making a console app exec a 2nd executable.</li>
<li>assume the main application code is written in C/C++</li>
<li>bonus points if no GUI window is created when "--help" is specified. (i.e., no flicker from a short-lived window)</li>
</ul>
<p>In my experience the standard visual studio template for console app has no GUI capability, and the normal win32 template does not send its stdout to the parent cmd shell.</p>

54,539 | <p>So the SMEs at my current place of employment want to try and disable the back button for certain pages. We have a page where the user makes some selections and submits them to be processed. In some instances they have to enter a comment on another page. </p>
<p>What the users have figured out is that they don't have to enter a comment if they submit the information and go to the page with the comment and then hit the back button to return to the previous page. </p>
<p>I know there are several different solutions to this (and many of them are far more elegant then disabling the back button), but this is what I'm left with. Is it possible to prevent someone from going back to the previous page through altering the behavior of the back button. (like a submit -> return false sorta thing). </p>
<p>Due to double posting information I can't have it return to the previous page and then move to the current one. I can only have it not direct away from the current page. I Googled it, but I only saw posts saying that it will always return to the previous page. I was hoping that someone has some mad kung foo js skills that can make this possible.</p>
<p>I understand that everyone says this is a bad idea, and I agree, but sometimes you just have to do what you're told.</p>
