• How to calculate order (big O) for more complex algorithms (ie quicksort)

  - by bangoker

  I know there are quite a bunch of questions about big O notation, I have already checked Plain english explanation of Big O , Big O, how do you calculate/approximate it?, and Big O Notation Homework--Code Fragment Algorithm Analysis?, to name a few. I know by "intuition" how to calculate it for n, n^2, n! and so, however I am completely lost on how to calculate it for algorithms that are log n , n log n, n log log n and so. What I mean is, I know that Quick Sort is n log n (on average).. but, why? Same thing for merge/comb, etc. Could anybody explain me in a not to math-y way how do you calculate this? The main reason is that Im about to have a big interview and I'm pretty sure they'll ask for this kind of stuff. I have researched for a few days now, and everybody seem to have either an explanation of why bubble sort is n^2 or the (for me) unreadable explanation a la wikipedia Thanks!

• Prevent Visual Studio Web Test from changing request details

  - by keithwarren7

  I have a service that accepts Xmla queries for Analysis services, often times those queries themselves will have a string that contains a fragment that looks something like {{[Time].[Year].[All]}} Recording these requests works fine but when I try to re-run the test I get an error from the test runner... Request failed: Exception occurred: There is no context parameter with the name ' [Time].[Year].[All]' in the WebTestContext This was confusing for some time but when I asked VS to generate a coded version of the test I was able to see the problem a bit better. VS searches for the '{{' and '}}' tokens and makes changes, considering those areas to refer to Context parameters, the code looks like this.Context["\n\t[Time].[Year].[All]"].ToString() Anyone know how to instruct Visual Studio to not perform this replacement operation? Or another way around this issue?

• C2244 when trying to call the pow function from inline assembly

  - by schrödingers cat

  I would like to call the pow function from inline assembly. The problem is i'm getting error C2244: 'pow' : unable to match function definition to an existing declaration. I'm new to assembly so this may be a trivial question but how do i resolve this? I guess it has something to do with the compiler not beeing able to properly resolve the overload of pow. The following code fragment is causing the error: do_POW: // push first argument to the stack sub esp, size value_type fld qword ptr [ecx] fstp qword ptr [esp] // push second argument to the stack sub esp, size value_type fld qword ptr [ecx - size value_type] fstp qword ptr [esp]and pop fpu stack // call the pow function call pow sub ecx, size value_type fstp qword ptr [ecx] add esp, 2 * size value_type jmp loop_start

• tchar safe functions -- count parameter for UTF-8 constants

  - by Dustin Getz

  I'm porting a library from char to TCHAR. the count parameter of this fragment, according to MSDN, is the number of multibyte characters, not the number of bytes. so, did I get this right? _tcsncmp(access, TEXT("ftp"), 3); //or do i want _tcsnccmp? "Supported on Windows platforms only, _mbsncmp and _mbsnbcmp are multibyte versions of strncmp. _mbsncmp will compare at most count multibyte characters and _mbsnbcmp will compare at most count bytes. They both use the current multibyte code page. _tcsnccmp and _tcsncmp are the corresponding Generic functions for _mbsncmp and _mbsnbcmp, respectively. _tccmp is equivalent to _tcsnccmp."

• Sending html data via $post fails

  - by Neil

  I am using the code below which is fine but when I use the code below that in an attempt to send an html fragment to a processing page to save it as a file but I get nothing. I have tried using ajax with processData set to false ads dataTypes of html, text and xml but nothing works. I can't find anything on this so I guess I must be missing something fairly trivial but I've been at it for 3 hours now. This works $.post("SaveFile.aspx", {f: "test4.htm", c: "This is a test"}, function(data){ alert(data); }, "text"); This fails $.post("SaveFile.aspx", {f: "test4.htm", c: "<h1>This is a test</h1>"}, function(data){ alert(data); }, "text");

• P2 Touchpoint chmod not working?

  - by Michael

  I'm using Eclipse 3.5.2 and I've created a p2.inf with the following information: instructions.install = \ chmod(targetDir:@artifact,targetFile:$os$/libfoo.so,permissions:755); instructions.install.import= \ org.eclipse.equinox.p2.touchpoint.natives.chmod I placed the p2.inf inside the META-INF folder of the fragment, but when I install the update site, libfoo.so does not have execute permissions. After pulling my hair out, I tried a p2.inf referencing a non-existing *.so, but nothing seems to happen. No error messages, exceptions, or warnings of any kind to indicate the P2 touchpoint action failed... What's the deal? Any ideas?

• Java BufferedWriter close()

  - by rakeshr

  Hi, assume that I have the following code fragment operation1(); bw.close(); operation2(); When I call BufferedReader.close() from my code, I am assuming my JVM makes a system call that ensures that the buffer has been flushed and written to disk. I want to know if close() waits for the system call to complete its operation or does it proceed to operation2() without waiting for close() to finish. To rephrase my question, when I do operation2(), can I assume that bw.close() has completed successfully?

• What is the most EVIL code you have ever seen in a production enterprise environment?

  - by Registered User

  What is the most evil or dangerous code fragment you have ever seen in a production environment at a company? I've never encountered production code that I would consider to be deliberately malicious and evil, so I'm quite curious to see what others have found. The most dangerous code I have ever seen was a stored procedure two linked-servers away from our core production database server. The stored procedure accepted any NVARCHAR(8000) parameter and executed the parameter on the target production server via an double-jump sp_executeSQL command. That is to say, the sp_executeSQL command executed another sp_executeSQL command in order to jump two linked servers. Oh, and the linked server account had sysadmin rights on the target production server.

• a question on webpage data scraping using Java

  - by Gemma

  Hi there. I am now trying to implement a simple HTML webpage scraper using Java.Now I have a small problem. Suppose I have the following HTML fragment. <div id="sr-h-left" class="sr-comp"> <a class="link-gray-underline" id="compare_header" rel="nofollow" href="javascript:i18nCompareProd('/serv/main/buyer/ProductCompare.jsp?nxtg=41980a1c051f-0942A6ADCF43B802'); " Compare Showing 1 - 30 of 1,439 matches, The data I am interested is the integer 1.439 shown at the bottom.I am just wondering how can I get that integer out of the HTML. I am now considering using a regular expression,and then use the java.util.Pattern to help get the data out,but still not very clear about the process. I would be grateful if you guys could give me some hint or idea on this data scraping. Thanks a lot.

• jQuery - events won't fire for dynamically created tab elements..

  - by Amit

  Hi, I am using jQuery UI Tabs. <div id="tabs"> <ul id="tablist"> <li><a href="#fragment-1"><span>One</span></a></li> </ul> </div> I have a button that adds new tabs. I use the following code: var newTabId = $('#tabs').tabs('option', 'selected') + 1; $('#tabs').tabs("add",'someUrl.htm','New Tab',newTabId); (Tab will be added next to the currently selected tab) Now none of the newly added tabs fire any events such as a click or hover $('#tablist li').click(function(){ alert('test message'); }); But events fire properly for the tabs that were there in the initial source code. How to resolve?

• mkdir error in bash script

  - by Don

  Hi, The following is a fragment of a bash script that I'm running under cygwin on Windows: deployDir=/cygdrive/c/Temp/deploy timestamp=`date +%Y-%m-%d_%H:%M:%S` deployDir=${deployDir}/$timestamp if [ ! -d "$deployDir" ]; then echo "making dir $deployDir" mkdir -p $deploydir fi This produces output such as: making dir /cygdrive/c/Temp/deploy/2010-04-30_11:47:58 mkdir: missing operand Try `mkdir --help' for more information. However, if I type /cygdrive/c/Temp/deploy/2010-04-30_11:47:58 on the command-line it succeeds, why does the same command not work in the script? Thanks, Don

• HLSL How can one pass data between shaders / read existing colour value?

  - by RJFalconer

  Hello all, I have 2 HLSL ps2.0 shaders. Simplified, they are: Shader 1 Reads texture Outputs colour value based on this texture Shader 2 Needs to read in existing colour (or have it passed in/read from a register) Outputs the final colour which is a function of the previous colour (They need to be different shaders as I've reached the maximum vertex-shader outputs for 1 shader) My problem is I cannot work out how Shader 2 can access the existing fragment/pixel colour. Is the only way for shaders to interact really just the alpha blending options? These aren't sufficient if I want to use the colour as input to my function.

• Eclipse RCP : make a standalone plugin extending an existing standalone one

  - by akira2x3x

  I have extended via extension point (add menus and functionnalities) an already existing plugin which has it's own product definition file and it's own class Application implements IApplication. I want to create a Product Configuration(customize splash screen,etc...). Does my plugin need an Application class? I want my plugin to be independant, Standalone with a launcher. Not a fragment. Do I have to inherit already existing plugin Application? Thanks for the tips and tricks.

• Scala model-view-presenter, traits

  - by Ralph

  I am a fan of Martin Fowler's (deprecated) model-view-presenter pattern. I am writing a Scala view class containing several button classes. I would like to include methods to set the action properties of the buttons, to be called by the presenter. A typical code fragment looks like this: private val aButton = new JButton def setAButtonAction(action: Action): Unit = { aButton.setAction(action) } This code is repeated for each button. If Java/Scala had the C preprocessor, I would create a macro to generate this code, given the button name (no lectures on the evils of the C preprocessor, please). This code is obviously very verbose and repetitive. Is there any better way way to do this in Scala, perhaps using traits? Please hold the lectures about scala.swing. I looking for a general pattern here.

• How to check connection leak using regular expression ?

  - by gauravkarnatak

  I have to check connection leak in my application i.e. open connections which have not been closed. After searching, after I found out that a thousands times connections have been opened but I can't manually go to each and every code fragment and check for connection close thing. I think, it could be possible using a regular expression but the fact is, I am not that well versed with regex that I could write one. Please suggest a regular expression for checking in a no of java files that a opened connection has been closed or not. My code pattern is something like this. try { /* Some code goes here */ con = EJBUtil.getConnection(JNDI_NAME); /* Some code goes here */ } finally { /* Some code goes here */ DBUtil.close(con); or closeConnection.close(con); /* Some code goes here */ }

• Quick question about pointers

  - by xbonez

  So, I have this code fragment: int * iPtr ; int * jPtr ; int i = 5, k = 7; iPtr = &i; jPtr = iPtr ; I have just started learning about pointers, and need to get some doubts cleared. is jPtr now essentially also pointing at i? I know I can change the value of i by using *iPtr, but how can I change the value of the object being pointed to by jPtr? How will changing the object being pointed to by jPtr affect the value of the object pointed to by iPtr, and i ?

• How to render consistence and smooth moving animation on iphone / ipod / iphone simulator.

  - by shakthi

  I am trying render a simple animation(object movement animations) on iphone. I used opengl for object rendering. Movements appears to be smooth on the simulator. But if I used same code in the ipod, object movement is slower. In the iphone it is still slower. I googled a bit and found 'frame rate independent rendering method', which taught me the concept of 'time interval' and object movement based on it. However result is very unpleasant. There is a lot of jerk in the animation even when fps remains above 20. Following code fragment is used for calculation of time interval between successive frames and I am using that to move my animation. NSTimeInterval GetTimeIntervals(NSTimeInterval * inLastElapsedTime ) { NSTimeInterval intervalTime = 0; NSTimeInterval currentTime = [NSDate timeIntervalSinceReferenceDate]; if(*inLastElapsedTime != 0 ) { intervalTime = currentTime - *inLastElapsedTime; } *inLastElapsedTime = currentTime; return intervalTime; }

• Actionbar scherlock is not refreshed when the orientation is changed

  - by SavasCinar

  I use Sherlock action bar in my application. I used "ifRoom|withText" feature in my menu. If I test my code in portrait mode, I can see only icon and if I rotate orientation to landscape, still I see only icon. On the other hand, if I run with landscape, I can see text and icon on portrait and landscape. This means that When the screen is rotated, action bar is not refreshed. How can I fix? In menu, I have android:showAsAction="ifRoom|withText" Also I used this line in my manifest file to fixed android:configChanges="keyboardHidden|orientation|screenSize" but it didn't work. And I run my code android 2.3 Also I used fragment in my activity, FragmentManager fm = getSupportFragmentManager(); ft = fm.beginTransaction(); mFragment1 = fm.findFragmentByTag("f1"); if (mFragment1 == null) { mFragment1 = new MenuFragment(); ft.add(mFragment1, "f1"); } ft.commit();

• Discovering maximum packet size

  - by ereOn

  I'm working on a network-related project and I am using DTLS (TLS/UDP) to secure communications. Reading the specifications for DTLS, I've noted that DTLS requires the DF flag (Don't Fragment) to be set. On my local network if I try to send a message bigger than 1500 bytes, nothing is sent. That makes perfect sense. On Windows the sendto() reports a success but nothing is sent. I obviously cannot unset the DF flag manually since it is mandatory for DTLS and i'm not sure whether the 1500 bytes limit (MTU ?) could change in some situations. I guess it can. So, my question is : "Is there a way to discover this limit ?" If not, what would be the lowest possible value ? My software runs under UNIX (Linux/MAC OSX) and Windows OSes so different solutions for each OS are welcome ;) Many thanks.

• Processing an n-ary ANTLR AST one child at a time

  - by Chris Lieb

  I currently have a compiler that uses an AST where all children of a code block are on the same level (ie, block.children == {stm1, stm2, stm3, etc...}). I am trying to do liveness analysis on this tree, which means that I need to take the value returned from the processing of stm1 and then pass it to stm2, then take the value returned by stm2 and pass it to stm3, and so on. I do not see a way of executing the child rules in this fashion when the AST is structured this way. Is there a way to allow me to chain the execution of the child grammar items with my given AST, or am I going to have to go through the painful process of refactoring the parser to generate a nested structure and updating the rest of the compiler to work with the new AST? Example ANTLR grammar fragment: block : ^(BLOCK statement*) ; statement : // stuff ; What I hope I don't have to go to: block : ^(BLOCK statementList) ; statementList : ^(StmLst statement statement+) | ^(StmLst statement) ; statement : // stuff ;

• Resource interpreted as other but transferred with MIME type text/html.

  - by Zhami

  I'm transferring fragments of HTML via Ajax. Safari (4.0.5) reports: "Resource interpreted as other but transferred with MIME type text/html." The file name of the file I get has a .html extension. The server does set the header for this: Content-Type:text/html As I said, the content is a fragment of HTML, which is injected into the page (with jQuery). The contents of the file look like: <html> ... some valid html ... </html> What else might Safari need to see to make it interpret the received content as HTML? TIA.

• Django 1.2 crash course needed

  - by delusionalweekendwarrior

  I know Python but I've never used Django. What do I need to know about Django 1.2 to port my typical PHP CRUD web application in one weekend? (Yes I've read Joel Spolsky's Netscape article :-)) I'm reading this tutorial right now and it's excellent. I'm already playing around with inspectdb to generate my models from the existing schema. I'm planning to use the following features of Django this weekend: Fragment caching Static asset versioning (for far future expires) Schema migrations (or whatever they're called in Django) Auto-admin (and customize it later) The test framework ...other stuff I probably don't know about yet I'm familiar with all these concepts in other languages/frameworks, except for the ORM which I've never used. I know SQL pretty well though. Any links, sage bits of advice, gotchas, stuff not mentioned in the (excellent) tutorial/docs, or stuff that is mentioned but warrants repeating == very welcome. Thanks!

• Writing to the middle of the file (without overwriting data)

  - by Andreas Bonini

  In windows is it possible through an API to write to the middle of a file without overwriting any data and without having to rewrite everything after that? If it's possible then I believe it will obviously fragment the file; how many times can I do it before it becomes a serious problem? If it's not possible what approach/workaround is usually taken? Re-writing everything after the insertion point becomes prohibitive really quickly with big (ie, gigabytes) files. Note: I can't avoid having to write to the middle. Think of the application as a text editor for huge files where the user types stuff and then saves. I also can't split the files in several smaller ones.
