  • Bibliography with BibLaTeX

    - by Tim
    I'm using the MLA style. I would like to print out a bibliography subdivided into different sections. I also want annotations on each source. Is this possible with BibLaTeX? Should I just do it manually?

  • The "Why" behind PMD's rules.

    - by James Kingsbery
    Is there a good resource which describes the "why" behind PMD rule sets? PMD's site has the "what" - what each rule does - but it doesn't describe why PMD has that rule and why ignoring that rule can get you in trouble in the real world. In particular, I'm interested in knowing why PMD has the AvoidInstantiatingObjectsInLoops and OnlyOneReturn rules (the first seems necessary if you need to create a new object corresponding to each object in a collection, the second seems like it is a necessity in many cases that return a value based on some criteria). Just to be clear, I know that I can disable these and how to do that, I'm just wondering why they are there in the first place. Sorry if there's something obvious I missed out there, but I did a Google search and SO search before posting this.

  • Finding the string length of a integer in .NET

    - by James Newton-King
    In .NET what is the best way to find the length of an integer in characters if it was represented as a string? e.g. 1 = 1 character 10 = 2 characters 99 = 2 characters 100 = 3 characters 1000 = 4 characters The obvious answer is to convert the int to a string and get its length but I want the best performance possible without the overhead of creating a new string.

  • MVC: capture route url's and pass them to javascript function

    - by Tim Geerts
    Short:Is there a way to have a route-definition that will pass the "CONTROLLER/ACTION" string value to a javascript function in stead of actually going straight for the controller action? More:I have a masterpage which contains the navigation of the site. Now, all the pages need this navigation wrapped around it at all times, but because I didn't want the navigation to constantly load with each pagecall, I changed all my pages to partialviews. These partial views are loaded via the JQuery.Load() method whenever a menu item is clicked in the navigation. This all worked very good, up till now because I noticed it's also a requirement of the website to be able to link directly to page X, rather then default.aspx. So, as an example:The main page is my "default.aspx" page, this utilizes my master page with the nagivation around it. And each call to a new page uses a javascript function that loads that particular partial view inside a div that is known in my masterpage. So, the url never changes away from "default.aspx", but my content changes seemlesly. The problem is, those url's also need to be available when typed directly into the address bar. But, they're partial views, so loading them directly from the address bar makes them display without any masterpages around them. Therefore my question if it might be possible to capture the route typed into the address bar and pass that on to my javascript function that will load that route in the content div. (I hope I explained it ok enough, if not, feel free to ask more information)

  • What is your preferred tool stack for PHP development in the Windows Environment?

    - by Tim Visher
    I have been developing basic web sites for awhile now with some PHP thrown in for getting dynamic stuff done. However, I recently decided that it was time I got my hands a little dirtier so I wanted to start to play with the underpinnings of Wordpress and other such apps. I work on a Mac at home and have been using Coda for most of my editing needs and I love it. Also, to manage the services stack I use MAMP at home. However, I've begun to realize that for heavy PHP and Web work (AJAX, etc.), more is needed. I'm very interested to hear the kinds of tools more experienced web developers use on a day to day basis to manage the entire work flow. I found this article over on developer tutorials and decided to go with XAMPP (for the moment) for managing the services. However, IDE, Source Control, Debugger, etc. are all up for grabs. Anyway, your thoughts are much appreciated. And, if at all possible, try to describe your entire stack with what each tool fulfills for your development process.

  • struct method linking

    - by James
    I'm updating some old code that has several POD structs that were getting zero'd out by memset (don't blame me...I didn't write this part). Part of the update changed some of them to classes that use private internal pointers that are now getting wiped out by the memset. So I added a [non-virtual] reset() method to the various structs and refactored the code to call that instead. One particular struct developed an "undefined reference to `blah::reset()'" error. Changing it from a struct to a class fixed the error. Calling nm on the .o file h, the mangled function names for that method look the same (whether it's a class or a struct). I'm using g++ 4.4.1, on Ubuntu. I hate the thought that this might be a compiler/linker bug, but I'm not sure what else it could be. Am I missing some fundamental difference between structs and classes? I thought the only meaningful ones were the public/private defaults and the way everyone thinks about them.

  • Issue with org.apache.commons.net.ftp.FTPClient listFiles()

    - by James P.
    The listFiles() method of org.apache.commons.net.ftp.FTPClient works fine with Filezilla server on 127.0.0.1 but returns null on the root directory of public FTP servers such as belnet.be. There is an identical question on the link below but enterRemotePassiveMode() doesn't seem to help. http://stackoverflow.com/questions/2339855/apache-commons-ftpclient-listfiles Could it be an issue with list parsing? If so, how can go about solving this?

  • How to make Flash 'play well with others'?

    - by Sensei James
    What up fam. So this isn't a question asking about memory management schemes; for those of you who may not know, the Flash Virtual Machine relies on garbage collection by using reference counting and mark and sweep (for good coverage of these topics, check out Grant Skinner's article and presentation). And yes, Flash also provides the "delete" operator, which can (unfortunately only) be used to remove the properties of dynamic objects. What I want to know is how to make it so that Flash programs don't continue to consume CPU and memory while running in the background (save loading content or communicating remotely, for example). The motivation for this question comes in part from Apple's ban on cross compiled applications (in its SDK 4) on the grounds that they do not behave as predicted with the multitasking feature central to iPhone OS 4. My intention is not only to make Flash programs that will 'pass muster' as far as multitasking in iPhone OS 4, but also to simply make better (behaving) Flash programs. Put another way, how might a Flash application mimic the multitasking feature of iPhone OS 4? Does the Flash API provide the means for a developer to put their applications to 'sleep' while other programs run, and then to 'awaken' them just as quickly? In our own program, we might do something as crude as detecting when the user has been idle (no mouse motion or key press) for (say) four seconds: var idle_id:uint = setInterval(4000, pause_program); var current_movie_clip:MovieClip; var current_frame:uint; ... // on Mouse move or key press... clearInterval(idle_id); idle_id = setInterval(4000, pause_program); ... function pause_program():void { current_movie_clip = event.target as MovieClip; current_frame = current_movie_clip.currentFrame; MovieClip(root).gotoAndStop("program_pause_screen"); } (on the program pause screen) resume_button.addEventListener(MouseEvent.CLICK, resume_program); function resume_program(event:MouseEvent) { current_movie_clip.gotoAndPlay(current_frame); } If that's the right idea, what's the best way to detect that an application should be shelved? And, more importantly, is it possible for Flash Player to detect that some of its running programs are idle, and to similarly shelve them until the user performs an action to resume them? (Please feel free to answer as much or as little of the many questions I've posed.)

  • Need advice on organizing two WPF applications within one Visual Studio solution

    - by Tim
    I have a WPF application (KaleidoscopeApplication) organized as follows: Solution (6 projects) Cryptography (DLL) Rfid (DLL) KaleidoscopeApplication (buildable "startup project") Basically, KaleidoscopeApplication contains a bunch of resources (sounds, images, etc) and your standard WPF junk (App.xaml, App.xaml.cs, other xaml and code). I need to create a new application that is very similar to Kaleidoscope, but I'm not sure of the best way to organize. This new app will need access to much of the same code and resources as Kaleidoscope. Preferably, I would like to create a new project in the solution, then simply use the "set as startup project" to pick which app I want to build. However, will I be able to access (share) the Resources folder of Kaleidoscope? I know I will be able to access much of the code if I simply add a reference to the project and include a "using Kaleidoscope". But the resources I'm not so sure about. Is this the right way to organize or am I asking for trouble in the future? Thanks in advance!

  • Trying to use contains selector within nested divs

    - by James
    <div> <div>test</div> </div> $("div:contains('test')").css('display','none'); I know I am going to kick myself on this. The problem is that when this runs all divs are hidden due to nesting. How do I make it so that the parent div does not get hidden? I am limited to using 1.2.6

  • Stop a stopwatch

    - by James Morgan
    I have the following code in a JPanel class which is added to a another class (JFrame). What I'm trying to implement is some sort of a stopwatch program. startBtn.addActionListener(new startListener()); class startListener implements ActionListener { public void actionPerformed(ActionEvent e) { Timer time = new Timer(); time.scheduleAtFixedRate(new Stopwatch(), 1000, 1000); } } This is another class which basically the task. public class Stopwatch extends TimerTask { private final double start = System.currentTimeMillis(); public void run() { double curr = System.currentTimeMillis(); System.out.println((curr - start) / 1000); } } The timer works fine and this is definitely far from complete but I'm not sure how to code the stop button which should stop the timer. Any advice on this? BTW I'm using java.util.timer

  • Make seems to think a prerequisite is an intermediate file, removes it

    - by James
    For starters, this exercise in GNU make was admittedly just that: an exercise rather than a practicality, since a simple bash script would have sufficed. However, it brought up interesting behavior I don't quite understand. I've written a seemingly simple Makefile to handle generation of SSL key/cert pairs as necessary for MySQL. My goal was for make <name> to result in <name>-key.pem, <name>-cert.pem, and any other necessary files (specifically, the CA pair if any of it is missing or needs updating, which leads into another interesting follow-up exercise of handling reverse deps to reissue any certs that had been signed by a missing/updated CA cert). After executing all rules as expected, make seems to be too aggressive at identifying intermediate files for removal; it removes a file I thought would be "safe" since it should have been generated as a prereq to the main rule I'm invoking. (Humbly translated, I likely have misinterpreted make's documented behavior to suit my expectation, but don't understand how. ;-) Edited (thanks, Chris!) Adding %-cert.pem to .PRECIOUS does, of course, prevent the deletion. (I had been using the wrong syntax.) Makefile: OPENSSL = /usr/bin/openssl # Corrected, thanks Chris! .PHONY: clean default: ca clean: rm -I *.pem %: %-key.pem %-cert.pem @# Placeholder (to make this implicit create a rule and not cancel one) Makefile: @# Prevent the catch-all from matching Makefile ca-cert.pem: ca-key.pem $(OPENSSL) req -new -x509 -nodes -days 1000 -key ca-key.pem $@ %-key.pem: $(OPENSSL) genrsa 2048 $@ %-cert.pem: %-csr.pem ca-cert.pem ca-key.pem $(OPENSSL) x509 -req -in $ $@ Output: $ make host1 /usr/bin/openssl genrsa 2048 ca-key.pem /usr/bin/openssl req -new -x509 -nodes -days 1000 -key ca-key.pem ca-cert.pem /usr/bin/openssl genrsa 2048 host1-key.pem /usr/bin/openssl req -new -days 1000 -nodes -key host1-key.pem host1-csr.pem /usr/bin/openssl x509 -req -in host1-csr.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 host1-cert.pem rm host1-csr.pem host1-cert.pem This is driving me crazy, and I'll happily try any suggestions and post results. If I'm just totally noobing out on this one, feel free to jibe away. You can't possibly hurt my feelings. :)

  • RSS feed created with PHP only shows the title in the feed reader

    - by James Simpson
    I am using the following PHP code to generate the XML for an RSS feed, but it doesn't seem to be working correctly. No short description is displayed in the feed reader, all I see is the title of the article. Also, all of the articles say they were published at the same time. This is the first time I have tried to setup an RSS feed, so I'm sure I've made several stupid mistakes. $result = mysql_query("SELECT * FROM blog ORDER BY id DESC LIMIT 10"); $date = date(DATE_RFC822); header('Content-type: text/xml'); echo ("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"); echo ("<rss version=\"2.0\">\n"); echo ("<channel>\n"); echo ("<lastBuildDate>$date</lastBuildDate>\n"); echo ("<pubDate>$date</pubDate>\n"); echo ("<title>my website name</title>\n"); echo ("<description><![CDATA[the description]]></description>\n"); echo ("<link>http://my-domain.com</link>\n"); echo ("<language>en</language>\n"); $ch=100; while ($a = mysql_fetch_array($result)) { $headline = htmlentities(stripslashes($a['subject'])); $posturl = $a[perm_link]; $content = $a['post']; $date = date(DATE_RFC822, $a['posted']); echo ("<item>\n"); echo ("<title>$headline</title>\n"); echo ("<link>$posturl</link>\n"); echo ("<description><![CDATA[$content]]></description>\n"); echo ("<guid isPermaLink=\"true\">$posturl</guid>\n"); echo ("<pubDate>$date2</pubDate>\n"); echo ("</item>\n"); } echo ("</channel>\n"); echo ("</rss>\n");

  • String comparison in Objective-C

    Hey, I've currently got a webserver set up which I communicate over SOAP with my iPhone app. I am returning a string containing a GUID and when I attempt to compare this with another string I get some strange results: Why would this not fire? Surely the two strings are a match? Thanks

  • Why is IHttpAsyncHandler being called over IHttpHandler?

    - by Tim Hardy
    I made a custom handler that derives from MvcHandler. I have my routes using a custom RouteHandler that returns my new handler for GetHttpHandler(), and I override ProcessRequest() in my custom handler. The call to GetHttpHandler is triggering a breakpoint and my handler's constructor is definitely being called, but BeginProcessRequest() is being called on the base MvcHandler instead of ProcessRequest(). Why are the async methods being called when I haven't done anything to call them? I don't want asynchronous handling, and I certainly didn't do anything explicit to get it. My controllers all derive from Controller, not AsyncController. I don't have the source code with me right now, but I can add it later if needed. I was hoping someone might know some of the reasons why BeginProcessRequest might be called when it's not wanted.

  • Why am I seeing a crash when trying to call CDHtmlDialog::OnInitDialog()

    - by Tim
    I added a helpAbout menu item to my mfc app. I decided to make the ddlg derive from CDHTMLDialog. I override the OnInitDialog() method in my derived class and the first thing I do is call the parent's OnInitDialog() method. I then put in code that sets the title. On some machines this works fine, but on others it crashes in the call to CDHtmlDialog::OnInitDialog() - Trying to read a null pointer. the call stack has nothing useful - it is in mfc90.dll Is this a potential problem with mismatches of mfc/win32 dlls? It works on my vista machines but crashes on a win2003 server box. BOOL HTMLAboutDlg::OnInitDialog() { // CRASHES on the following line CDHtmlDialog::OnInitDialog(); CString title = "my title"; // example of setting title // i try to get version info //set the title CModuleVersion ver; char filename[ _MAX_PATH ]; GetModuleFileName( AfxGetApp()->m_hInstance, filename, _MAX_PATH ); ver.GetFileVersionInfo(filename); // get version from VS_FIXEDFILEINFO struct CString s; s.Format("Version: %d.%d.%d.%d\n", HIWORD(ver.dwFileVersionMS), LOWORD(ver.dwFileVersionMS), HIWORD(ver.dwFileVersionLS), LOWORD(ver.dwFileVersionLS)); CString version = ver.GetValue(_T("ProductVersion")); version.Remove(' '); version.Replace(",", "."); title = "MyApp - Version " + version; SetWindowText(title); return TRUE; // return TRUE unless you set the focus to a control } And here is the relevant header file: class HTMLAboutDlg : public CDHtmlDialog { DECLARE_DYNCREATE(HTMLAboutDlg) public: HTMLAboutDlg(CWnd* pParent = NULL); // standard constructor virtual ~HTMLAboutDlg(); // Overrides HRESULT OnButtonOK(IHTMLElement *pElement); HRESULT OnButtonCancel(IHTMLElement *pElement); // Dialog Data enum { IDD = IDD_DIALOG_ABOUT, IDH = IDR_HTML_HTMLABOUTDLG }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support virtual BOOL OnInitDialog(); DECLARE_MESSAGE_MAP() DECLARE_DHTML_EVENT_MAP() }; I can't figure out what is going on - why it works on some machins and crashes on others. Both have VS2008 installed EDIT: VS versions VISTA - no crashes 9.0.30729.1 SP 2003 server: (crashes) 9.0.21022.8 RTM

  • How to synchronize SQL Server 2008 database with SQL Server 2005 database?

    - by James McFarland
    I am using VS 2008 Team Suite and SQL Server 2008 in my development environment. I am deploying to a shared-host website with shared-host SQL Server 2005. I want to push changes from my development environment to my production host. I tried using Data | Schema Compare... and it reports to me that it does not support SQL Server 2008. What do people use for this (Besides Red-Gate tools - I use those at my day job, and they rock...this is a volunteer thing for my son's school)? I am looking for something very inexpensive if not free.

  • How to use IObservable/IObserver with ConcurrentQueue or ConcurrentStack

    - by James Black
    I realized that when I am trying to process items in a concurrent queue using multiple threads while multiple threads can be putting items into it, the ideal solution would be to use the Reactive Extensions with the Concurrent data structures. My original question is at: http://stackoverflow.com/questions/2997797/while-using-concurrentqueue-trying-to-dequeue-while-looping-through-in-parallel/ So I am curious if there is any way to have a LINQ (or PLINQ) query that will continuously be dequeueing as items are put into it. I am trying to get this to work in a way where I can have n number of producers pushing into the queue and a limited number of threads to process, so I don't overload the database. If I could use Rx framework then I expect that I could just start it, and if 100 items are placed in within 100ms, then the 20 threads that are part of the PLINQ query would just process through the queue. There are three technologies I am trying to work together: Rx Framework (Reactive LINQ) PLING System.Collections.Concurrent structures

  • jQuery UI sortable issue with helper Y offset value being same as scroll offset on FireFox only

    - by James
    I have a problem with a jQuery UI 1.7.2 sortable list in Firefox, IE7-8 work fine. When I'm scrolled down a bit, the helper element seems to have an offset of the same height that I'm scrolled down from the mouse pointer which makes it impossible to see which item you originally started dragging. How do I fix this or work around the issue? If there is no fix what is a really good alternative drag-able plugin? Here are my initialization parameters for the sortable. $("#sortable").sortable( {placeholder: 'ui-state-highlight' } ); $("#sortable").disableSelection();
