401,783 | <p>Given the following Java code for generating a binary file:</p>
<pre><code>DataOutputStream out = new DataOutputStream(new FileOutputStream("foo.dat"));
out.writeInt(1234);
out.writeShort(30000);
out.writeFloat(256.384f);
</code></pre>
<p>I'm using the following Objective-C code and manage to parse the int and the short values:</p>
<pre><code>NSString *path = [[NSBundle mainBundle] pathForResource:@"foo" ofType:@"dat"];
NSFileHandle *file = [NSFileHandle fileHandleForReadingAtPath:path];
unsigned long intValue;
memcpy(&intValue, [[file readDataOfLength:4] bytes], 4);
intValue = NSSwapBigLongToHost(intValue);
unsigned short shortValue;
memcpy(&shortValue, [[file readDataOfLength:2] bytes], 2);
shortValue = NSSwapBigShortToHost(shortValue);
</code></pre>
<p>My problem for now is with the float value: any clues on how to parse it?</p>

<p>The idea suggested is to sort the letters in the word, and also run length encode repeated letters. So, for example "mississippi" first becomes "iiiimppssss", and then could be further shortened by encoding as "4impp4s".</p>
<p>I'm relatively new to ruby and though I could hack something together, I'm sure this is a one liner for somebody with more experience of ruby. I'd be interested to see people's approaches and improve my ruby knowledge.</p>
<p><em>edit: to clarify, performance of computing the signature doesn't much matter for my application. I'm looking to compute the signature so I can store it with each word in a large database of words (450K words), then query for words which have the same signature (i.e. all anagrams of a given word, that are actual english words). Hence the focus on space. The 'elegant' part is just to satisfy my curiosity.</em></p>

<p>Any advice?</p>

401,856 | <p>It's generally accepted that copy and paste programming is a bad idea, but what is the best way to handle a situation where you have two functions or blocks of code that really <strong>do</strong> need to be different in just a few ways make generalizing them extremely messy? </p>
<p>What if the code is substantially the same, except for a few minor variations, but those few minor variations aren't in things that are easy to factor out through either adding a parameter, template methods, or something like that?</p>
<p>More generally, have you ever encountered a situation where you would admit that a little copy-and-paste coding was truly justified.</p>

401,908 | <p>I've run into an odd problem and I'm not sure how to fix it. I have several classes that are all PHP implementations of JSON objects. Here' an illustration of the issue</p>
<pre><code>class A
{
protected $a;
public function __construct()
{
$this->a = array( new B, new B );
}
public function __toString()
{
return json_encode( $this->a );
}
}
class B
{
protected $b = array( 'foo' => 'bar' );
public function __toString()
{
return json_encode( $this->b );
}
}
$a = new A();
echo $a;
</code></pre>
<p>The output from this is</p>
<pre><code>[{},{}]
</code></pre>
<p>When the <em>desired</em> output is</p>
<pre><code>[{"foo":"bar"},{"foo":"bar"}]
</code></pre>
<p>The problem is that I was relying on the __toString() hook to do my work for me. But it can't, because the serialize that json_encode() uses won't call __toString(). When it encounters a nested object it simply serializes public properties only.</p>
<p>So, the question then become this: Is there a way I can develop a managed interface to JSON classes that both lets me use setters and getters for properties, but also allows me to get the JSON serialization behavior I desire?</p>
<p>If that's not clear, here's an example of an implementation that <em>won't</em> work, since the __set() hook is only called for the initial assignment</p>
<pre><code>class a
{
public function __set( $prop, $value )
{
echo __METHOD__, PHP_EOL;
$this->$prop = $value;
}
public function __toString()
{
return json_encode( $this );
}
}
$a = new a;
$a->foo = 'bar';
$a->foo = 'baz';
echo $a;
</code></pre>
<p>I suppose I could also do something like this</p>
<pre><code>class a
{
public $foo;
public function setFoo( $value )
{
$this->foo = $value;
}
public function __toString()
{
return json_encode( $this );
}
}
$a = new a;
$a->setFoo( 'bar' );
echo $a;
</code></pre>
<p>But then I would have to rely on the diligence of the other developers to use the setters - I can't force adherence programmtically with this solution.</p>
<p><strong>---> EDIT <---</strong></p>
<p>Now with a test of Rob Elsner's response</p>
<pre><code><?php
class a implements IteratorAggregate
{
public $foo = 'bar';
protected $bar = 'baz';
public function getIterator()
{
echo __METHOD__;
}
}
echo json_encode( new a );
</code></pre>
<p>When you execute this, you can see that the getIterator() method isn't ever invoked.</p>

401,919 | <p>The code base I'm currently working on is littered with hard-coded values.</p>
<p>I view all hard coded values as a code smell and I try to eliminate them where possible...however there are some cases that I am unsure about.</p>
<p>Here are two examples that I can think of that make me wonder what the best practice is:</p>
<pre><code>1. MyTextBox.Text = someCondition ? "Yes" : "No"
2. double myPercentage = myValue / 100;
</code></pre>
<p>In the first case, is the best thing to do to create a class that allows me to do MyHelper.Yes and MyHelper.No or perhaps something similar in a config file (though it isn't likely to change and who knows if there might ever be a case where its usage would be case sensitive).</p>
<p>In the second case, finding a percentage by dividing by 100 isn't likely to ever change unless the laws of mathematics change...but I still wonder if there is a better way.</p>
<p>Can anyone suggest an appropriate way to deal with this sort of hard coding? And can anyone think of any places where hard coding is an acceptable practice?</p>

402,022 | <p>I'm working on an application that runs on Windows Mobile 6 that needs to be able to retrieve all items from an item table that contain a given string (provided by the end user) within the item's description field. The problem is that there are approximately 170,000 items in the table. Since I need to return all items that contain the string anywhere within the description I'm forced to use a LIKE %string%, which eliminates any chance to use the index. The data and table structure are originally based on a Progress database, which has a wonderful contains operator on any word-indexed fields. This is not the case on our mobile application, since it uses SQL Server Compact 3.5.</p>
<p>Basically, my DAL runs the query and retrieves an SqlCeDataReader and then uses an ItemFactory to create a List object that contains only the matched items. This obviously lets us keep our domain/business objects separate from the data access layer.</p>
<p>Fine and dandy, except for the 8m and 42s that it takes to retrieve items when I search for all items that contain something like "golf" in the description. Obviously this is not an acceptable time frame for the end user.</p>
<p>My first attempt was to instead retrieve all items back from the database using SELECT * FROM Item" (with an order by clause on one of the main indexed fields). At this point I ran an IndexOf check as I ran through the SqlCeDataReader and had the ItemFactory only add items to the List object if they contained the requested description text. This improved the speed down to 1m 46s. Not too shabby, but still too slow.</p>
<p>I then tried another approach that showed promise... almost... While the application starts up, I tried creating a List that contained all item objects within the database (takes about 2 minutes to run the query and populate the entire list, but at least it's only once as the app is initializing... still... ugh). Once the list is complete, I can easily run queries on that list doing things such as the following (I hope my syntax is right... I'm not at work right now and I don't have Visual Studio on the pc I'm sitting at):</p>
<pre><code>List<Item> specificItems =
AllItems.FindAll(i => i.Description.IndexOf(searchString, StringComparison.OrdinalIgnoreCase) >= 0);
</code></pre>
<p>This approach knocked it down to 21s. Very nice (still slow though in the grand scheme of things). However, the problem is that the memory usage is way too great if I load all the items from the database. I had to actually cut off the last 20,000 items (so the 21s time frame probably would have been more like 25s) during the initial load, because an OutOfMemoryException was being thrown. According to the memory manager on the emulator, I still had about 20 MB of free RAM, but I've heard that a process can only have 32 MB or RAM associated to it (not sure if that's true for WM 6, but it appears so).</p>
<p>To make sure it wasn't because I was using a List object to hold all the items (which I was instantiating with the needed capacity in its constructor to avoid dynamic resizing), which I've also read may cause extra memory usage when it implicity calls EnsureCapacity, I tried using an Item[] array (sized ahead of time). This still had the memory issue and the size difference was negligible.</p>
<p>Ok enough rambling. I know I'm likely going to have to some how limit the records returned from the database by the datareader (through some indexed search on a different type of field) and then will likely use indexOf on that smaller subset of items to get maximum performance (thus skipping the Like operator all together). This will cause the end user to have to enter more than just a description search though (perhaps item hierarchy information to limit which type of items to search within).</p>
<p>Any ideas? Am I going about this the wrong way?</p>
<p>Thanks for listening (sorry this post is long, I'm kind of thinking out loud).</p>
<p>Oh I should add (just in summary) what I'm using:</p>
<ul>
<li>Windows Mobile 6 </li>
<li>Sql Server Compact Edition 3.5</li>
<li>C# 3.5</li>
</ul>
<p>UPDATE: While the Bloom Filter approach mentioned below seemed interesting, I could not fulfill one requirement (which I didn't really specify above). I can't really match words that are contained inside other words (e.g. "club" would not return "clubs"). Due to this, I was forced to use a different approach altogether (Kent Fredric... thanks for pointing this out). I've marked Kent's answer as the correct one, since his approach was the one that filled the most requirements (Mitch, your's had a similar issue as the Bloom filter suggested by Jaunder). However, I have gone a different approach (for now...) than his way as well.</p>
<p>What I've done is pulled all item objects into memory, with only item numbers and descriptions (which keeps it under the memory limitations, however it still does cause a longer initialization than I like... multithreading and loading that information behind the scenes while the application is running can take care of that I guess). To perform the searches I've written my own contains routine. The routine is written in unmanaged c# code that uses two pointers and a couple of loops to run through the description and the required matching text. If it finds a match anywhere in the description, it adds the item number to an array. Once all items have been searched, a new query goes back to the database and grabs only the matching item numbers (which is very fast due to the index on an integer field). Then those items are created in a List with all information (not just the item number and description). The whole operation takes approximately 5 - 10 seconds (depending on the description), which is good enough for now.</p>
<p>I'll still look into further optimizing this (might be able to track how many characters the search term is... if there are less characters remaining on the item description than the required text, the loop could continue straight to the next item).</p>
<p>Any suggestions are still welcome. For now I have marked Kent's answer as "the most correct" for my question.</p>
<p>Props to Dolch for helping me write the contains routine.</p>

402,065 | <p>it seems I have run into a problem with Internet Explorer 7.
I have an html page that has links to files on another server. The server I am linking to checks the referrer of the request and if the referrer is valid, it allows access to the resource. It works fine in firefox 2 and 3 (as the server my html page is located on is a valid referer) but in internet explorer it doesn't work, the other server denies me the resource(generates an http 403 error). I was doing some searching and stumbled on this <a href="http://support.microsoft.com/kb/178066" rel="noreferrer">http://support.microsoft.com/kb/178066</a> and I have tried the html page in both https and http and same thing for the server I am connecting to but I get nothing Internet explorer. what can I do to work around this?</p>
<p>thank you</p>

402,077 | <p>A coworker asked me to look at indexing on some tables because his query was running very long. Over an hour.</p>
<pre><code>select count(1)
from databaseA.dbo.table1
inner join databaseA.dbo.table2 on (table1.key = table2.key)
inner join databaseB.dbo.table3 on (table1.key = table3.key)
</code></pre>
<p>Note the different databases. This was being run from DatabaseB</p>
<p>Tables 1 and 2 were over 2 million records long. Table3 had a dozen records or so.</p>
<p>I looked at the query plan and the optimizer decided to do nested-loop index seeks into tables 1 and 2 with Table3 as the driving table!</p>
<p>My first assumption was that statistics were seriously messed up on Tables1 & 2 but before updating statistics I tried adding a join hint thusly:</p>
<pre><code>select count(1)
from databaseA.dbo.table1
inner HASH join databaseA.dbo.table2 on (table1.key = table2.key)
inner join databaseB.dbo.table3 on (table1.key = table3.key)
</code></pre>
<p>Results returned in 15 seconds.</p>
<p>Since I was short on time, I passed the results back to him but I'm worried that this might result in problems down the road.</p>
<p>Should I revisit the statistics issue and resolve the problem that way? Could the bad query plan have resulted from the join being from a separate databases?</p>
<p>Can anyone offer me some ideas based on your experience?</p>

402,086 | <p>I'm new to LaTeX and I must say that I am really struggling with it. I discovered the \newcommand command that is kind of like a function/method in regular programming languages. You can give it arguments and everything.</p>
<p>I was wondering though, can I somehow iterate in LaTeX? Basically, what I would like to do is create a table with N+1 columns where the first row just contains a blank cell and then the numbers 1, 2, ..., N in the other columns. I only want to give N as an argument to this 'function' (newcommand).</p>
<p>Here is an example of something that might look like what I'm looking for (although obviously this won't work):</p>
<pre>\newcommand{\mytable}[2]{
\begin{tabular}{l|*{#1}{c|}} % table with first argument+1 columns
for(int i = 1; i <= #1; i++) "& i" % 'output' numbers in different columns
\\\hline
letters & #2 % second argument should contain actual content for row
\\\hline
\end{tabular}
}</pre>
<p>Call it with:</p>
<pre>\mytable{3}{a & b & c}</pre>
<p>Output should be:</p>
<pre> | 1 | 2 | 3 |
--------+---+---+---+
letters | a | b | c |
--------+---+---+---+</pre>
<p>Does anyone know if something like this is possible?</p>
<p>Thanks!</p>

402,094 | <p>I have a DropDownList and a TextBox on a Page. When the user chooses the "other" option in the DropDownList I want to display a TextBox just to the right of it. I do not want to use the traditional PostBack technique. I want this interaction to be client side.</p>
<p>I am aware that I can get a get a reference to the DOM element and set its style to "display:none" or "display:". What I am looking for is something that is built into the ASP.NET framework for handling something like this. I mean, in jQuery this is as simple as <code>$('controlID').hide</code>. Is there a Control Extender that can do this? Is jQuery part of the ASP.NET framework yet?</p>

402,159 | <p>I messed up on my SVN repository and now need to revert the entire repository from revision 28 to 24 and don't want to deal with diffs or conflicts. Is there a quick and simple way to do this? I've been able to revert back single files before fine with the merge command - but in this instance it wants to add all of the files back into the repository from revision 28 when all I really want to do is delete them.</p>
<p>I am using the command line on a linux box (bash).</p>
<p>Thanks</p>
<p><strong>EDIT</strong></p>
<p>Thanks for all of the help! I fixed it by:</p>
<pre><code>svnadmin create /svnroot/<repo>.fixed
svnadmin dump -r 1:24 /svnroot/<repo> --incremental > dump.svn
svnadmin load /svnroot/<repo>.fixed < dump.svn
</code></pre>
<p>Then putting the old repo in a backup location and moving the repo.fixed to repo.</p>
<p>Thanks again!</p>

402,200 | <p>Supposing I'm setting a background image for a web page in CSS like this:</p>

margin-right: auto;
margin: 0;
padding: 0;
background: url(images/desk.gif) repeat bottom left;
}

<p>Is there any way to layer a second image on top of the desk.gif within the body element itself, or is the only way to create a separate class and use the z axis?</p>
<p>Sorry, it's a simpleminded question, but I've been trying to figure this out and though I haven't been able to make it work, I also haven't found a clear slapdown of the idea anywhere online... so, is there a way, or is this just a no can do?</p>

402,217 | <p>I need to store some data in a Django model. These data are not equal to all instances of the model.</p>
<p>At first I thought about subclassing the model, but I’m trying to keep the application flexible. If I use subclasses, I’ll need to create a whole class each time I need a new kind of object, and that’s no good. I’ll also end up with a lot of subclasses only to store a pair of extra fields.</p>
<p>I really feel that a dictionary would be the best approach, but there’s nothing in the Django documentation about storing a dictionary in a Django model (or I can’t find it).</p>
<p>Any clues?</p>

402,247 | <p>I have been programming in Java since 2004, mostly enterprise and web applications. But I have never used <em>short</em> or <em>byte</em>, other than a toy program just to know how these types work. Even in a <em>for loop</em> of 100 times, we usually go with <em>int</em>. And I don't remember if I have ever came across any code which made use of <em>byte</em> or <em>short</em>, other than some public APIs and frameworks.</p>
<p>Yes I know, you can use a <em>short</em> or <em>byte</em> to save memory in large arrays, in situations where the memory savings actually matters. Does anyone care to practice that? Or its just something in the books.</p>
<p><strong>[Edited]</strong></p>
<p>Using <em>byte</em> arrays for network programming and socket communication is a quite common usage. Thanks, Darren, to point that out. Now how about <em>short</em>? Ryan, gave an excellent example. Thanks, Ryan.</p>

402,250 | <p>I'm using an iframe to display content that has links. When the user clicks around in the iFrame and hits "back," it goes back in the iFrame. This behavior is OK. However, once they're back to the first page of the iFrame and they hit "back" again, the entire window is taken back to the previous page. This is unwanted.</p>
<p>To prevent this behavior, I've put a fake "back" button within the iFrame. (In most cases this is bad UI, in this case, it works well). I'd like this fake back button to only go back if the previous page is the iFrame's page -- not the entire page. <strong>When they hit the fake back button in the iFrame, it should only move that iFrame back, nothing else.</strong> Is there a way to do this? Does an iFrame get its own history object?</p>
<p>Something that might be of benefit: the domain of the iFrame and the main window can be assumed to be distinct. So, if it's possible to read the "global" history object, I can check to see if the previous page was mine by checking to see if the domain is mine. If the domain is not mine, the fake back button will be hidden or not do anything.</p>
<p>Help greatly appreciated, and happy holidays!</p>

402,299 | <p>I'm relatively new to ASP.NET and was wondering if anyone could shed some light on when I should use relative references (e.g. ../images/banner_tinga.jpg) versus the tilde (e.g. ~/images/banner_tinga.jpg). Depending on the situation you can accomplish the same goal using either. What are the pros and cons of each mechanism? One argument for the relative reference seems to be Visual Studio's design time dislike for resources referenced by the tilde. Whenever I reference a css file that why it indicates it can not be found.</p>

402,307 | <p>I was wondering what the best way to model a relationship where an object is associated with exactly n objects of another class. I want to extend the has_one relationship to a specific value of n. </p>
<p>For example, a TopFiveMoviesList would belong to user and have exactly five movies. I would imagine that the underlying sql table would have fields like movie_id_1, movie_id_2, ... movie_id_5. </p>
<p>I know I could do a has_many relationship and limit the number of children at the model level, but I'd rather not have an intermediary table. </p>

402,313 | <p>I recently upgraded a Web Application Project (as well as some dependent projects) from .net 2.0 to .net 3.5 using the built in conversion tool. Everything works well such as using MS AJAX 3.5 vs. the external MS AJAX libraries in 2.0.</p>
<p>My problem occurs when I tried using the new Lambda Expression syntax. The compiler will not recognize Lambda Expressions as valid syntax. The target frame work version is set to 3.5 in all projects in the solution.I was also able to successfully use Lambda Expressions in a Library Project in the same solution.</p>
<p>The is the code that is giving me the error. Nothing too special.</p>
<pre><code>ObjectFactory.Initialize(x =>
{
x.ForRequestedType<IUnitIdSequencingService>().TheDefaultIsConcreteType<UnitIdSequencingService>();
x.ForRequestedType<IGadgetDAO>().TheDefault.Is.OfConcreteType<GadgetDAO>().WithCtorArg("instance").EqualToAppSetting("OSHAInspectionManager");
});
</code></pre>
<p>The specific errors I am getting are:</p>
<pre><code>Error 102 Invalid expression term '>' D:\projects\bohlco\pmr\PMR\Web\App_Code\Bootstrapper.cs 13 41 D:\...\Web\
</code></pre>
<p>Any help would be greatly appreciated. I have been searching Google with little luck</p>

402,314 | <p>In a way following on from <a href="https://stackoverflow.com/questions/158534/reading-a-windows-dmp-file">reading a windows *.dmp file</a></p>
<p>Having received a dump file from random customer, running the debug session to see the crash, you often find it is in a MS or other third party library. The next issue is that you may not have knowledge of the PC setup to such an extent that you can ensure you have the actually modules available. </p>
<p>For instance I'm currently stuck trying to get symbols to load for ntdll.dll (5.01.2600.5512). In MSVC 2005 the path column in the modules list window shows a * before the fully pathed file name, and refuses to load symbols I have downloaded for XP/SP1/SP1a/SP2/SP3.</p>
<p>I have the symbol server setup to download from the internet and store in a local cache which seems to have been working fine for modules that I do have on my PC.
Using GUI equivelant to the method </p>
<pre>
Set _NT_SYMBOL_PATH=srv*d:\SymbolCache*\\server1\Third-Party-PDB;srv*d:\SymbolCache*\\server2\Windows\Symbols*http://msdl.microsoft.com/download/symbols
</pre>
<p>Perhaps I have the wrong symbols, but as new ones are not downloading where do I go to next? Do I have to contact the customer and ask what SP they have installed, and any other patches? Do I have to install that machine and then run up the debugger with the dmp file to get the symbols I need?</p>

<p>How can i get the functionality in the above command programmatically? Like, is it possible to run as:</p>

<p>and get the same result? I tried using URLClassLoader but it modifies the classpath and does not add to it.</p>
<p>Thanx!</p>
<hr>
<p>Thanks for the response Milhous. But that is what i am trying to do.. How is it possible to get the jar into the classpath first? I tried using a custom classloader too :(</p>
<p>That works.. But sorry that i need to run it only as:
java parserTester
I would like to know if such a thing is possible???</p>
<p>It needs to be so bcoz i have parserTester.java and .class in a separate folder. I need to retain the file structure. The parserTester makes use of a jar in a separate jar folder.</p>

402,348 | <p>I need to set/get the cookies stored at <code>first.example</code> while browsing <code>second.example</code>, I have full access of <code>first.example</code> but I only have JavaScript access (can manipulate the DOM as I want) on <code>second.example</code>.</p>
<p>My first approach was to create an iframe on <code>second.example</code> (with JS) that loaded a page like <code>first.example/doAjax?setCookie=xxx</code> and that did an AJAX call to say <code>first.example/setCookie?cookieData=xxx</code> which would set the cookie on <code>first.example</code> with the data we passed around.</p>
<p>That pretty much worked fine for setting the cookie on <code>first.example</code> from <code>second.example</code> - for getting a cookie I basically followed the same procedure, created the iframe that loaded <code>first.example/doAjax?getCookie</code> and that would do an AJAX call to say <code>first.example/getCookie</code> which would read the cookie info on <code>first.example</code> and return it as a JSON object.</p>
<p>The problem is that I'm unable to bring that JSON cookie object back to <code>second.example</code> so I can read it, well maybe I could just bring it when the AJAX call is complete using "window.top" but there's timing issues because its not relative to when the iframe has been loaded. I hope I am clear and was wondering if there's an easier solution rather than this crazy iframe->ajax crap, also seems like this won't even work for getting cookies in SAFARI.</p>

402,432 | <p>I am trying to return an array Data Member from one smaller 2D Array Object, and trying to insert the array into a larger 2D array object. But when attempting this, I came into two problems.</p>
<p>First problem is that I want to return the name of the 2D array, but I do not know how to properly syntax to return 2D Array name.</p>
<p>This is what my 2D Array data member looks like</p>
<pre>
private:
int pieceArray[4][4];
// 2D Smaller Array
</pre>
<p>and I want to return this array into a function, but this one causes a compiler error:</p>
<pre>
int Piece::returnPiece()
{
return pieceArray; //not vaild
// return the 2D array name
}
</pre>
<p>I tired using this return type and it worked:</p>
<pre>
int Piece::returnPiece()
{
return pieceArray[4][4];
}
</pre>
<p>But I am unsure if this is what I want, as I want to return the array and all of it's content.</p>
<p>The other problem is the InsertArray() function, where I would put the returnPiece() function in the InsertArray()'s argument.</p>
<p>The problem with the InsertArray() is the argument, heres the code for it:</p>
<pre>
void Grid::InsertArray( int arr[4][4] ) //Compiler accepts, but does not work
{
for(int i = 0; i < x_ROWS ; ++i)
{
for (int j = 0; j < y_COLUMNS ; ++j)
{
squares[i][j] = arr[i][j];
}
}
}
</pre>
<p>The problem with this is that it does not accept my returnPiece(), and if i remove the "[4][4]", my compiler does not accept.</p>
<p>Mostly all these are syntax errors, but how do I solve these problems?</p>
<ol>
<li>Returning the whole pieceArray in returnPiece()</li>
<li>The correct syntax for the argument in InsertArray()</li>
<li>The argument of InsertArray() accepting the returnPiece()</li>
</ol>
<p>These 3 are the major problems that I need help with, and had the same problem when I attempt to use the pointer pointer method. Does anyone know how to solve these 3 problems?</p>

402,474 | <p>I'm a student of web development (and college), so my apologies if this comes off sounding naive and offensive, I certainly don't mean it that way. My experience has been with PHP and with a smallish project on the horizon (a glorified shift calendar) I hoped to learn one of the higher level frameworks to ease the code burden. So far, I looked at CakePHP Symfony Django and Rails.</p>
<p>With PHP, the URLs mapped very simply to the files, and it "just worked". It was quick for the server, and intuitive. But with all of these frameworks, there is this inclination to "pretty up" the URLs by making them map to different functions and route the parameters to different variables in different files. </p>
<p>"The Rails Way" book that I'm reading admits that this is dog slow and is the cause of most performance pains on largish projects. My question is "why have it in the first place?"? Is there a specific point in the url-maps-to-a-file paradigm (or mod_rewrite to a single file) that necessitates regexes and complicated routing schemes? Am I missing out on something by not using them?</p>
<p>Thanks in advance!</p>

402,483 | <p>I currently have a unittest.TestCase that looks like..</p>
<pre><code>class test_appletrailer(unittest.TestCase):
def setup(self):
self.all_trailers = Trailers(res = "720", verbose = True)
def test_has_trailers(self):
self.failUnless(len(self.all_trailers) > 1)
# ..more tests..
</code></pre>
<p>This works fine, but the <code>Trailers()</code> call takes about 2 seconds to run.. Given that <code>setUp()</code> is called before each test is run, the tests now take almost 10 seconds to run (with only 3 test functions)</p>
<p>What is the correct way of caching the <code>self.all_trailers</code> variable between tests?</p>
<p>Removing the setUp function, and doing..</p>
<pre><code>class test_appletrailer(unittest.TestCase):
all_trailers = Trailers(res = "720", verbose = True)
</code></pre>
<p>..works, but then it claims "Ran 3 tests in 0.000s" which is incorrect.. The only other way I could think of is to have a cache_trailers global variable (which works correctly, but is rather horrible):</p>
<pre><code>cache_trailers = None
class test_appletrailer(unittest.TestCase):
def setUp(self):
global cache_trailers
if cache_trailers is None:
cache_trailers = self.all_trailers = all_trailers = Trailers(res = "720", verbose = True)
else:
self.all_trailers = cache_trailers

402,503 | <p>I have developed code with Ajax and jQuery. I have got a response from my.php, and I have
tried to extract the values of the response. Here the code (HTML):</p>
<h3>My.php</h3>
<pre><code>?php
echo '<div id="title">My Title </div>';
echo '<div id="message"> My message </div>';
?>
</code></pre>
<p>I try to extract the title and message so my code is below.</p>
<pre><code> <head>
<script type="text/javascript" src="js/jquery-1.2.6.js"></script>
<script type="text/javascript">
$(document).ready(function() {
alert("OK");
$.ajax({
type:"POST",
url: "my.php",
cache:false ,
success: function(data){
$("#response").html(data);
var $response = $(data);
var oneval = $response.find('#title').text();
var subval = $response.find('#message').text();
alert(oneval);
}
});
});
</script>
</head>
<body>
<div id="response">
</div>
</body>
</html>
</code></pre>
<p>...</p>
<p>The problem is when I tried to alert, it is not working. What is wrong with this logic? Should I use another function to extract the title and message?</p>

402,514 | <p>I was reading some Java recently and came across something (an idiom?) new to me: in the program, classes with multiple constructors would also always include a blank constructor. For example: </p>
<pre><code>public class Genotype {
private boolean bits[];
private int rating;
private int length;
private Random random;
public Genotype() { // <= THIS is the bandit, this one right here
random = new Random();
}
/* creates a Random genetoype */
public Genotype(int length, Random r) {
random = r;
this.length = length;
bits = new boolean[length];
for(int i=0;i<length;i++) {
bits[i] =random.nextBoolean();
}
}
/* copy constructor */
public Genotype(Genotype g,Random r) {
random = r;
bits = new boolean[g.length];
rating = g.rating;
length = g.length;
for(int i=0;i<length;i++) {
bits[i] = g.bits[i];
}
}
}
</code></pre>
<p>The first constructor doesn't seem to be a "real" constructor, it seems as though in every case one of the other constructors will be used. So why is that constructor defined at all?</p>

402,522 | <p>I use SVN as the source control system, and I wonder how to compare directories while ignoring any metadata differences. Is there a way to tell <code>svn diff</code> to compare only the actual content and ignore any metadata? </p>
<p>I mean metadata like SVN properties, etc. that don't affect the file content. Assume file X has an additional property in branch B compared to trunk T. Unfortunately it will show up in 'svn diff T B' even though the actual content of file X is the same.</p>
<p>I look for something like this:</p>
<pre><code>svn diff https://example.org/tags/v1 https://example.org/tags/v2 -x -ignore-metadata --summarize
</code></pre>
<p><strong>Update:</strong> I partially solved this by diff'ing directly on the filesystem instead of using the SVN tools. See my own answer below...</p>

402,541 | <p>How can I have that functionality in my game through which the players can change their hairstyle, look, style of clothes, etc., and so whenever they wear a different item of clothing their avatar is updated with it.</p>
<p>Should I:</p>
<ul>
<li><p>Have my designer create all possible combinations of armor, hairstyles, and faces as sprites (this could be a lot of work).</p></li>
<li><p>When the player chooses what they should look like during their introduction to the game, my code would automatically create this sprite, and all possible combinations of headgear/armor with that sprite. Then each time they select some different armor, the sprite for that armor/look combination is loaded.</p></li>
<li><p>Is it possible to have a character's sprite divided into components, like face, shirt, jeans, shoes, and have the pixel dimensions of each of these. Then whenever the player changes his helmet, for example, we use the pixel dimensions to put the helmet image in place of where its face image would normally be. (I'm using Java to build this game)</p></li>
<li><p>Is this not possible in 2D and I should use 3D for this?</p></li>
<li>Any other method?</li>

2) GUI developed in C++/QT which uses static lib.</p>

<p>Is it possible to do like this in Linux with eclipse?
I can easily follow same debugging procedure in Windows using Visual studio and attaching lib to GUI but I cannot find any good way to do here with eclipse.</p>
<p>I have tried many IDEs/debuggers like
Anjuta
Code Blocks.
DDD,Kdbg
but none is working properly.</p>

402,615 | <p>This is a idea for a security. Our employees shall have access to some commands on a linux server but not all. They shall e.g. have the possibility to access a log file (<code>less logfile</code>) or start different commands (<code>shutdown.sh</code> / <code>run.sh</code>).</p>
<p>Background information:</p>
<p>All employees access the server with the same user name: Our product runs with "normal" user permissions, no "installation" is needed. Just unzip it in your user dir and run it. We manage several servers where our application is "installed". On every machine there is a user <code>johndoe</code>. Our employees sometimes need access to the application on command line to access and check log files or to restart the application by hand. Only some people shall have full command line access.</p>
<p>We are using ppk authentication on the server.</p>
<p>It would be great if employee1 can only access the logfile and employee2 can also do X etc...</p>
<p><strong>Solution:</strong>
As a solution I'll use the <code>command</code> option as stated in the <em>accepted</em> answer. I'll make my own little shell script that will be the only file that can be executed for <em>some</em> employees. The script will offer several commands that can be executed, but no others. I'll use the following parameters in <code>authorized_keys</code> from as stated <a href="http://www.linuxjournal.com/article/8257" rel="noreferrer">here</a>:</p>
<pre><code>command="/bin/myscript.sh",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty
ssh-dss AAAAB3....o9M9qz4xqGCqGXoJw= user@host
</code></pre>
<p>This is enough security for us. Thanks, community!</p>

402,648 | <p>I actually have two questions regarding the same problem but I think it is better to separate them since I don't think they are related.</p>
<p>Background:
I am writing a Windows Mobile software in VB.NET which among its tasks needs to connect to a mail-server for sending and retrieving e-mails. As a result, I also need a Mime-parser (for decoding and encoding) the e-mails in order to get the attachments. First I thought, I would write a small "hack" to handle this issue (using ordinary string-parsing) but then I saw a project, written in C#, <a href="http://www.codeproject.com/KB/cs/MIME_De_Encode_in_C_.aspx?fid=209566&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=1202157" rel="nofollow noreferrer">at CodeProject</a> which I thought I would implement into my solution. I don't know much about C# so I simply made a class-library out of the classes and used it in my VB.NET-project. This library works very nicely when I am targeting the Net Framework on normal windows-computers however when I was going to make the same library targeting the Compact Net Framework, I ran into troubles. This is natural since the Compact Net Framework has more limits but I actually didn't get that many errors - only two although repeated in various places in the code.</p>
<p>One of the errors is the one cited in the subject of this question i.e. "No overload for method 'GetString' takes '1' arguments". As mentioned above, I don't know much about C# so I converted the class with the error online into VB-NET but still I don't understand much.. Here is the function which gives above indicated error:</p>
<pre><code>public virtual string DecodeToString(string s)
{
byte[] b = DecodeToBytes(s);
if(m_charset != null)
{
//ERROR ON THIS LINE
return System.Text.Encoding.GetEncoding(m_charset).GetString(b);
}
else
{
m_charset = System.Text.Encoding.Default.BodyName;
//ERROR ON THIS LINE
return System.Text.Encoding.Default.GetString(b);
}
}
</code></pre>
<p>If the complete source-code is needed for this class, then I can post it in another message in this thread or you can find it by downloading the code at the web-site mentioned above and by having a look at the class named MimeCode.cs.</p>
<p>Anyone who can help me out? Can I rewrite above function somehow to overcome this problem?</p>
<p>I thank you in advance for your help.</p>
<p>Kind regards and a Happy New Year to all of you.</p>
<p>Rgds,
moster67</p>

402,679 | <p>I’ve run into a limitation in the cURL bindings for PHP. It appears there is no easy way to send the same multiple values for the same key for postfields. Most of the workarounds I have come across for this have involved creating the URL encoded post fields by hand tag=foo&tag=bar&tag=baz) instead of using the associative array version of CURLOPT_POSTFIELDS.</p>
<p>It seems like a pretty common thing to need to support so I feel like I must have missed something. Is this really the only way to handle multiple values for the same key?</p>
<p>While this workaround might be considered workable (if not really annoying), my main problem is that I need to be able to do multiple values for the same key and also support file upload. As far as I can tell, file upload more or less requires to use the associate arravy version of CURLOPT_POSTFIELDS. So I feel like I am stuck.</p>
<p>I have <a href="http://curl.haxx.se/mail/curlphp-2008-12/0009.html" rel="noreferrer">posted</a> about this problem in more detail on the cURL PHP mailing list in the hopes that someone there has some ideas about this.</p>
<p>Suggestions or hints on where I can look for more information on this are greatly appreciated!</p>

402,785 | <p>we've got a list of search-result mappings, e.g. a simple url mapping might look like</p>
<p>"stackoverflow" -> "www.stackoverflow.com"
"joel" -> "www.joelonsoftware.com"</p>
<p>so searching for the exact phrases is working fine. </p>
<p>Now we're looking for an incremental search / typeahead, e.g. "stackover" would also return "www.stackoverflow.com". We could of course populate our maps accordingly, e.g. put every possible string into the map, starting with all variations of a given min size </p>
<p>-> map keys:</p>
<p>stack -> stackoverflow
...
stackoverf -> stackoverflow
stackoverfl -> stackoverflow
stackoverflo -> stackoverflow
stackoverflow -> stackoverflow</p>
<p>However that would mean a higher memory footprint that necessary (I guess).</p>
<p>Any suggestions?</p>

402,792 | <p>is there an easy away to combine fields in awk? Specifically, I have lines like this:</p>
<pre><code>1,2,some text
3,4,some text, but it has commas in it, annoyingly
</code></pre>
<p>I want to extract the two numbers as the first two fields, but then I want all of the text (commas and all) to be the third field. Is there a way to do that?</p>
<p>My basic awk call was like this:</p>
<pre><code>awk -F\, '{print $1"|"$2"|"$3}' file.txt
</code></pre>
<p>Which works fine for the first line, but stops at the comma in the text on the second line.</p>

402,817 | <p>I have two HTML tables which would ideally be placed side by side on the screen. Widescreen monitors will cope with this fine, but the tables are too wide to be side by side on most old-fashioned monitors. So I want to use css (or even just HTML, if possible) to place the tables side by side only if the resolution is high enough.</p>
<p>This works automatically with images, usually, but is there a way to do it for tables?</p>

402,832 | <p>I occasionally need to process a large amount of data from one package off the network, which takes sufficiently long that when the user tries to interact with the application windows adds the "(Not Responding)" string to the window title. I am aware this is because the processing is being done within a call to handle a message (some way up the stack) and therefore is blocking the message pump. I'm also aware the ideal way to deal with this is to process the data asynchronously in a separate thread so the pump can continue running, however this is a LARGE desktop application which is single threaded from top to toe and safely spinning this processing off is not feasible in our time frame.</p>
<p>So with that in mind, is there by any chance a way I can at least avoid the "not responding" moniker (which to most users reads as "has crashed") by telling windows my application is about to be busy before I begin the work? I believe there is something along these lines when responding to a request to close, one can keep asking windows for more time to avoid it proclaiming that your not "closing in a timely fashion"</p>
<p>I should add this is a C++ MFC application.</p>

<p>I was thinking of writing my own using Strings for each formula, regex for parsing them, etc., but let's assume my goal is to be as lazy as I can possibly get away with, and that if there's another option (especially a formal one), I'd rather try to use that instead, first.</p>
<p>Is there anything out there that does something like this?</p>

402,980 | <p>I'd like to use a single SQL query (in MySQL) to find the record which comes after one that I specify.</p>
<p>I.e., if the table has:</p>
<pre><code>id, fruit
-- -----
1 apples
2 pears
3 oranges
</code></pre>
<p>I'd like to be able to do a query like:</p>
<pre><code>SELECT * FROM table where previous_record has id=1 order by id;
</code></pre>
<p>(clearly that's not real SQL syntax, I'm just using pseudo-SQL to illustrate what I'm trying to achieve)</p>
<p>which would return:</p>
<pre><code>2, pears
</code></pre>
<p>My current solution is just to fetch all the records, and look through them in PHP, but that's slower than I'd like. Is there a quicker way to do it?</p>
<p>I'd be happy with something that returned two rows -- i.e. the one with the specified value and the following row.</p>
<p>EDIT: Sorry, my question was badly worded. Unfortunately, my definition of "next" is not based on ID, but on alphabetical order of fruit name. Hence, my example above is wrong, and should return oranges, as it comes alphabetically next after apples. Is there a way to do the comparison on strings instead of ids?</p>

402,996 | <p>I am having trouble deserializing my JSON string. I have a class of type <code>person</code> with public properties for sequence number of type int, first name, and last name. I want to pass an array of these objects in JSON format and have them deserialized as a list so I can loop through them on the server, but ASP.NET says something about not being supported to be deserialized as an array. I have validated the JSON I am producing, and it is valid. Is there something special about the JSON that ASP.NET needs to have before it can deserialize? The funny thing is if I serialize a list<person> object to JSON it looks exactly like the JSON I am producing. I must be missing something... To clarify, I'm using the ASP.NET Ajax library to deserialize. This is what I get back from the web service:</p>
<blockquote>
<p>{"Message":"Type \u0027System.Collections.Generic.IDictionary`2[[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Object, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]\u0027 is not supported for deserialization of an array."</p>
</blockquote>
<p>Actually unfortunately this doesn't seem to have anything to do with deserializing, it appears that you can't pass an array of JSON objects to an asmx web service. Am I correct? If you can't do that, is it possible to pass a collection of JSON objects to a web service and have them processed on the server with ASP.NET and C#?</p>
<h3>Update:</h3>
<p>OK, here is my code. Here is the person class:</p>
<pre><code>public class person
{
public person()
{
//
// TODO: Add constructor logic here
//
}
public int seq
{
get;
set;
}
public string firstName
{
get;
set;
}
public string lastName
{
get;
set;
}
}
</code></pre>
<p>And here is my JSON string:</p>
<pre><code>[{"seq":1,"firstName":"Chris","lastName":"Westbrook"},
{"seq":2,"firstName":"sayyl","lastName":"westbrook"}]
</code></pre>
<p>And here is the code I'm using</p>
<pre><code> [WebMethod]
public void updatePeople(string json)
{
IList<person> people =
new JavaScriptSerializer().Deserialize<IList<person>>(json);
//do stuff...
}
</code></pre>
