  • Why does File::Find finished short of completely traversing a large directory?

    - by Stan
    A directory exists with a total of 2,153,425 items (according to Windows folder Properties). It contains .jpg and .gif image files located within a few subdirectories. The task was to move the images into a different location while querying each file's name to retrieve some relevant info and store it elsewhere. The script that used File::Find finished at 20462 files. Out of curiosity I wrote a tiny recursive function to count the items which returned a count of 1,734,802. I suppose the difference can be accounted for by the fact that it didn't count folders, only files that passed the -f test. The problem itself can be solved differently by querying for file names first instead of traversing the directory. I'm just wondering what could've caused File::Find to finish at a small fraction of all files. The data is stored on an NTFS file system.

  • C++ - how does Sleep() and cin work?

    - by quano
    Just curious. How does actually the function Sleep() work (declared in windows.h)? Maybe not just that implementation, but anyone. With that I mean - how is it implemented? How can it make the code "stop" for a specific time? Also curious about how cin and those actually work. What do they do exactly? The only way I know how to "block" something from continuing to run is with a while loop, but considering that that takes a huge amount of processing power in comparison to what's happening when you're invoking methods to read from stdin (just compare a while (true) to a read from stdin), I'm guessing that isn't what they do.

  • Are there any tools to optimize the number of consumer and producer threads on a JMS queue?

    - by lindelof
    I'm working on an application that is distributed over two JBoss instances and that produces/consumes JMS messages on several JMS queues. When we configured the application we had to determine which threading model we would use, in particular the number of producing and consuming threads per queue. We have done this in a rather ad-hoc fashion but after reading the most recent columns by Herb Sutter in Dr Dobbs (in particular this one) I would like to size our threads in a more rigorous manner. Are there any methods/tools to measure the throughput of JMS queues (in particular JBoss Messaging queues) as a function of the number of producing/consuming threads?

  • how to write floating value accurately to a bin file.

    - by user319873
    Hi I am trying to dump the floating point values from my program to a bin file. Since I can't use any stdlib function, I am thinking of writting it char by char to a big char array which I am dumping in my test application to a file. It's like float a=3132.000001; I will be dumping this to a char array in 4 bytes. Code example would be:- if((a < 1.0) && (a > 1.0) || (a > -1.0 && a < 0.0)) a = a*1000000 // 6 bit fraction part. Can you please help me writting this in a better way.

  • JQUERY AJAX, Issues with spaces being sent to the server, y?

    - by nobosh
    I'm using the following code to post to the server which is then sent to a MYSQL query to find matches via search. $.ajax({ url: '/search/spotlight/', data: "q=" + $(this).val(), success: function(data) { } }); When Q's val has spaces in it, it's creating problems. I'm wondering if I'm handling this correctly? Do I need to encode the value in the AJAX call? Or is this a problem on my backend, which is ColdFusion Right now JQUERY is posting the following to the server: /search/spotlight/?q=FirstName%20LastName is this right?

  • Returning new base class when the parent class shared pointer is the return type

    - by Ben Dol
    Can you have a parent class shared pointer return type of a function and then return a new child class without it being a shared pointer? I'm not sure how shared pointers work in these situations, do they act like a regular pointer? Here is my example: BaseEventPtr Actions::getEvent(const std::string& nodeName) { if(asLowerCaseString(nodeName) == "action") return new ActionEvent(&m_interface); return nullptr; } ActionEvent is the subclass of BaseEvent in this situation. Cheers!

  • Getting users latest tweet with Django

    - by Hanpan
    I want to create a function which grabs every users latest tweet from a specific group. So, if a user is in the 'authors' group, I want to grab their latest tweet and then finally cache the result for the day so we only do the crazy leg work once. def latest_tweets(self): g = Group.objects.get(name='author') users = [] for u in g.user_set.all(): acc = u.get_profile().twitter_account users.append('http://twitter.com/statuses/user_timeline/'+acc+'.rss') return users Is where I am at so far, but I'm at a complete loose end as to how I parse the RSS to get there latest tweet. Can anyone help me out here? If there is a better way to do this, any suggestions are welcome! I'm sure someone will suggest using django-twitter or other such libraries, but I'd like to do this manually if possible. Cheers

  • DateTimeAxis - set Label to display Date + Time

    - by Jay
    Hi, Is there a way in flex 3 chart component to display both the date and time using horizontal DateTimeAxis? Currently the DateTimeAxis element has an attribute dataunits which allows to set the value to any of "milliseconds|seconds|minutes|hours|days|weeks|months|years" but I want to display the label as "2009/09/15 06:00:00" which includes the day and the time too. Here is the sample that i'm using [Bindable] public var deck:ArrayCollection = new ArrayCollection([ {date:"2009-09-15 06:00:00", close:42.71}, {date:"2009-09-16 06:15:00", close:42.99} ]); public function myParseFunction(s:String):Date { var sDate = s.substring(0,s.indexOf(" ")); var sTime = s.substring(s.indexOf(" ")); var aDate = sDate.split("-"); var aTime = sTime.split(":"); return new Date(aDate[0],(aDate[1]*1-1),aDate[2],aTime[0],aTime[1],aTime[2],0); } ]] Thanks in advance.

I found a similar question here but did not get it either...

  • Links sometimes not working in WebView

    - by littleFluffyKitty
    On occasion links in the WebView will not respond. The highlight press color will appear around them but nothing happens. I am also using WebViewClient's shouldOverrideUrlLoading and that function is not called when this happens. Edit: I have narrowed this issue down to the following circumstances: The webpage is the first page a WebView opens. The webpage uses meta name="viewport" attribute in the html head The WebView is using WebView.getSettings().setUseWideViewPort(true); Android 2.1 (Doesn't appear to happen in later versions, didn't test earlier) If a webpage meeting those above is opened no links will work. If another similar page is loaded, those links will not work either. It is not until you load a page without meta name="viewport" that links start to work. After a page without that meta attribute is opened and then you load a page with the meta viewport attribute, the links start working.

  • How to paste text and variables into a logical expression in R?

    - by Jasper
    I want to paste variables in the logical expression that I am using to subset data, but the subset function does not see them as column names when pasted (either with ot without quotes). I have a dataframe with columns named col1, col2 etc. I want to subset for the rows in which colx < 0.05 This DOES work: subsetdata<-subset(dataframe, col1<0.05) subsetdata<-subset(dataframe, col2<0.05) This does NOT work: for (k in 1:2){ subsetdata<-subset(dataframe, paste("col",k,sep="")<0.05) } for (k in 1:2){ subsetdata<-subset(dataframe, noquote(paste("col",k,sep=""))<0.05) } I can't find the answer; any suggestions?

  • Simplest way to extend doctrine for MVC Models

    - by RobertPitt
    Im developing my own framework that uses namespaces. Doctrine is already integrated into my auto loading system and im now at the stage where ill be creating the model system for my application Usually i would create a simple model like so: namespace Application\Models; class Users extends \Framework\Models\Database{} which would inherit all the default database model methods, But with Doctrine im still learning how it all works, as its not just a simple DBAL. I need to understand whats the part of doctrine my classes would extend where i can do the following: namespace Application\Models; class Users Extends Doctrine\Something\Table { public $__table_name = "users"; } And thus within the controller i would be able to do the following: public function Display($uid) { $User = $this->Model->Users->findOne(array("id" => (int)$id)); } Anyone help me get my head around this ?

  • hadoop mapper static initialisation

    - by rakeshr
    Hi, I have a code fragment in which I am using a static code block to initialize a variable. public static class JoinMap extends Mapper<IntWritable, MbrWritable, LongWritable, IntWritable> { ....... public static RTree rt = null; static { String rtreeFileName = "R.rtree"; rt = new RTree(rtreeFileName); } public void map(IntWritable key, MbrWritable mbr,Context context) throws IOException, InterruptedException { ......... List elements = rt.overlaps(mbr.getRect()); ....... } } My problem is that the variable rt in the above code fragment is not getting initialised. Can anybody suggest a fix or an alternate way to initialise the variable. I don't want to initialise it inside my map function since that slows down the entire process.

  • Proper error handling in a custom Zend_Autoloader?

    - by Pekka
    I'm building a custom autoloader based on Zend Framework's autoloading (related question here). The basic approach, taken from that question, is class My_Autoloader implements Zend_Loader_Autoloader_Interface { public function autoload($class) { // add your logic to find the required classes in here } } and then binding the new autoloader class to a class prefix. Now what I'm unsure about is how to handle errors inside the autoload method (for example, "class file not found") in a proper, ZF compliant way. I'm new to the framework, its conventions and style. Do I quietly return false and let the class creation process crash? Do I output an error or log message somehow (which would be nice to pinpoint the problem) and return false? If so, what is the Zend way of doing that? Do I trigger an error? Do I throw an exception? If so, what kind?

  • Downsampling the number of entries in a list (without interpolation)

    - by Dave
    I have a Python list with a number of entries, which I need to downsample using either: A maximum number of rows. For example, limiting a list of 1234 entries to 1000. A proportion of the original rows. For example, making the list 1/3 its original length. (I need to be able to do both ways, but only one is used at a time). I believe that for the maximum number of rows I can just calculate the proportion needed and pass that to the proportional downsizer: def downsample_to_max(self, rows, max_rows): return downsample_to_proportion(rows, max_rows / float(len(rows))) ...so I really only need one downsampling function. Any hints, please? EDIT The list contains objects, not numeric values so I do not need to interpolate. Dropping objects is fine.

  • Why should pop() take an argument?

    - by Stephano
    Quick background I'm a Java developer who's been playing around with C++ in my free/bored time. Preface In C++, you often see pop taking an argument by reference: void pop(Item& removed); I understand that it is nice to "fill in" the parameter with what you removed. That totally makes sense to me. This way, the person who asked to remove the top item can have a look at what was removed. However, if I were to do this in Java, I'd do something like this: Item pop() throws StackException; This way, after the pop we return either: NULL as a result, an Item, or an exception would be thrown. My C++ text book shows me the example above, but I see plenty of stack implimentations taking no arguments (stl stack for example). The Qustion How should one implement the pop function in C++? The Bonus Why?

  • Dll only loads correctly via LoadLibrary?

    - by Steve
    I'm trying to use dbghelp.dll. If I set it up in the VS2008 properties to point to the correct library and header file, and put dbghelp.dll in the same directory as the executable, one of the functions in the dll fails. If I LoadLibrary the dll, everything that function works. I've looked at the header that gets included via the VS option, and the right one is being pulled in. The correct lib is being pulled in (checked via /verbose option), and depends.exe shows the correct dll is loaded. Does anyone know why I can't get this to work? I'll probably just go with LoadLibrary, but I'm genuinely stumped on this one. EDIT: SymfromAddr fails with an "error 87", whatever that is. If I load the dll via LoadLibrary, it works.

  • Sinatra, JavaScript Cross-Domain Requests JSON

    - by pex
    I run a REST-API build on top of Sinatra. Now I want to write a jQuery Script that fetches data from the API. Sinatra is told to response with JSON before do content_type :json end A simple Route looks like get '/posts' do Post.find.to_json end My jQuery script is a simple ajax-call $.ajax({ type: 'get', url: 'http://api.com/posts', dataType: 'json', success: function(data) { // do something } }) Actually everything works fine as long as both runs on the same IP, API and requesting JS. I already tried to play around with JSONP for Rack without any positive results, though. Probably I just need a hint how to proceed.
