  • Problem with Restlet on GAE

    - by Leaf
    I'm trying to implement a calculator web service on GAE using Java Restlets... it works perfectly fine on localhost but when I upload my project to the Google App Engine everytime I try the web service link it says the link is broken. Here's the code I used: public Restlet createInboundRoot() { // Create a router Restlet that routes each call to a // new instance of HelloWorldResource. Router router = new Router(getContext()); Restlet restlet = new Restlet() { public void handle(Request request, Response response) { // Print the requested URI path String parameters = request.getResourceRef().getRemainingPart(); String message; if(parameters.charAt(0)=='?'){ message = "" + Calculator.calculate(parameters.substring(1)); } else { message = ""; } response.setEntity(message, MediaType.TEXT_PLAIN); } }; // Defines only one route router.attachDefault(restlet); return router; } The Application it's on is mapped to the /calcservice but as I said when I upload to GAE it comes back with a broken link error. I'm developing on Eclipse 3.4 and I'm wondering if there are any parameters I have to change to include the Restlet classes.

  • Setting objects (not users) inactive after period of time in asp.net mvc

    - by bastijn
    This question is mainly to verify my current idea. I have a series of objects which I want to be active for a specified amount of time. For instance objects like ads which are shown in the ad space only for the amount of time bought, objects in search results which should only pop up when active, and frontpage posts which should be set to inactive after a prespecified time. My current idea is to just give those type of objects a StartDate and EndDate and filter the search routines to only show results which fall in the range StartDate < currentDate < EndDate. Is this the normal structure or should there be some sort of auto-routine which routinely checks for objects which are "over-time" and set a property "inactive" to true or something. Seems like this approach is such a hassle since I need a checker which runs say, every 5 minutes, to scan all DB objects. Seems like a bad idea to me. So is the first structure the most commonly used or are there any other options? When searching on google or SO the search queries only return results setting users inactive.

  • What is optimal hardware configuration for heavy load LAMP application

    - by Piotr Kochanski
    I need to run Linux-Apache-PHP-MySQL application (Moodle e-learning platform) for a large number of concurrent users - I am aiming 5000 users. By concurrent I mean that 5000 people should be able to work with the application at the same time. "Work" means not only do database reads but writes as well. The application is not very typical, since it is doing a lot of inserts/updates on the database, so caching techniques are not helping to much. We are using InnoDB storage engine. In addition application is not written with performance in mind. For instance one Apache thread usually occupies about 30-50 MB of RAM. I would be greatful for information what hardware is needed to build scalable configuration that is able to handle this kind of load. We are using right now two HP DLG 380 with two 4 core processors which are able to handle much lower load (typically 300-500 concurrent users). Is it reasonable to invest in this kind of boxes and build cluster using them or is it better to go with some more high-end hardware? I am particularly curious how many and how powerful servers are needed (number of processors/cores, size of RAM) what network equipment should be used (what kind of switches, network cards) any other hardware, like particular disc storage solutions, etc, that are needed Another thing is how to put together everything, that is what is the most optimal architecture. Clustering with MySQL is rather hard (people are complaining about MySQL Cluster, even here on Stackoverflow).

  • inserting selected page from one word document in another word document with c#

    - by daemonkid
    I have a requirement to move selected pages from word DocumentA into another word DocumentB. So in the end DocumentB should have its own contents plus selected pages from DocumentA inserted at selected pages in DocumentB. The page number in DocumentB I will set thru properties. This is the code I am using to just append contents of DocumentA to DocumentB. object missing = System.Reflection.Missing.Value; Word._Application wordApp = new Word.Application(); Word._Document aDoc = new Word.Document(); try { wordApp.Visible = false; object readOnly = false; object isVisible = false; aDoc = wordApp.Documents.Open(ref fPath1, ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref isVisible, ref missing, ref missing, ref missing, ref missing); Word.Selection selection = wordApp.Selection; selection.InsertFile(fPath2, ref missing, ref missing, ref missing, ref missing); aDoc.Save(); wordApp.Quit(ref missing, ref missing, ref missing); } catch(Exception ex) { throw new Exception(ex.Message); } finally { wordApp = null; aDoc = null; } However, I keep getting this exception 'object reference not set to instance of object' at the line 'selection.InsertFile...' What is going wrong here? And how do I insert contents of page 2 from DocumentA into page 3 of DocumentB? Thanks for your time.

  • What do I name this class whose sole purpose is to report failure?

    - by Blair Holloway
    In our system, we have a number of classes whose construction must happen asynchronously. We wrap the construction process in another class that derives from an IConstructor class: class IConstructor { public: virtual void Update() = 0; virtual Status GetStatus() = 0; virtual int GetLastError() = 0; }; There's an issue with the design of the current system - the functions that create the IConstructor-derived classes are often doing additional work which can also fail. At that point, instead of getting a constructor which can be queried for an error, a NULL pointer is returned. Restructuring the code to avoid this is possible, but time-consuming. In the meantime, I decided to create a constructor class which we create and return in case of error, instead of a NULL pointer: class FailedConstructor : public IConstructor public: virtual void Update() {} virtual Status GetStatus() { return STATUS_ERROR; } virtual int GetLastError() { return m_errorCode; } private: int m_errorCode; }; All of the above this the setup for a mundane question: what do I name the FailedConstructor class? In our current system, FailedConstructor would indicate "a class which constructs an instance of Failed", not "a class which represents a failed attempt to construct another class". I feel like it should be named for one of the design patterns, like Proxy or Adapter, but I'm not sure which.

  • error detection/correction/recovery in serial protocols

    - by Jason S
    I have some designing to do for a serial protocol and am running into some questions that I figure must have been considered elsewhere. So I'm wondering if there are some recommendations for best practices in designing serial protocols. (Please either state a fact that is easily verifiable, or cite a reputable source if you make a claim.) General recommendations for websites/books are also welcome. In particular I have to deal with issues like parsing a stream of bytes into packets verifying a packet is correct (easy with a CRC, for instance) identifying reasonable types of errors that can occur (e.g. in a point-to-point serial stream, sporadic single bit errors, and dropped series of bytes, are both likely, but extra phantom bytes are unlikely; whereas with a record stored in flash memory or on a disk drive the types of errors that predominate are different) error correction or recovery (if I detect an error in a packet, can I correct it? If not, can I resync to the boundary of the next packet?) how to make variable-length packets robust to error correction / recovery. Any suggestions?

  • .NET client getting "not well formed" XML response from Axis web service

    - by Tex
    I have a simple .NET app that makes a SOAP call to a third party Axis web service. When I trace the HTTP traffic, I see that the Request looks fine, however I'm getting an exception: "Response is not well-formed XML." The return object is null, as it seems the XML can't be deserialized. One question regarding the various namespace declarations inside the wsdl. Several of these declarations point to URLs / domains that no longer exist. Could this cause any problems?

  • Serializing a DataType="time" field using XmlSerializer

    - by CraftyFella
    Hi, I'm getting an odd result when serializing a DateTime field using XmlSerializer. I have the following class: public class RecordExample { [XmlElement("TheTime", DataType = "time")] public DateTime TheTime { get; set; } [XmlElement("TheDate", DataType = "date")] public DateTime TheDate { get; set; } public static bool Serialize(Stream stream, object obj, Type objType, Encoding encoding) { try { using (var writer = XmlWriter.Create(stream, new XmlWriterSettings { Encoding = encoding })) { var xmlSerializer = new XmlSerializer(objType); if (writer != null) xmlSerializer.Serialize(writer, obj); } return true; } catch (Exception) { return false; } } } When i call the use the XmlSerializer with the following testing code: var obj = new RecordExample {TheDate = DateTime.Now.Date, TheTime = new DateTime(0001, 1, 1, 12, 00, 00)}; var ms = new MemoryStream(); RecordExample.Serialize(ms, obj, typeof (RecordExample), Encoding.UTF8); txtSource2.Text = Encoding.UTF8.GetString(ms.ToArray()); I get some strange results, here's the xml that is produced: <?xml version="1.0" encoding="utf-8"?> <RecordExample xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <TheTime>12:00:00.0000000+00:00</TheTime> <TheDate>2010-03-08</TheDate> </RecordExample> Any idea's how i can get the "TheTime" element to contain a time which looks more like this: <TheTime>12:00:00.0Z</TheTime> ...as that's what i was expecting?

  • Mocking Autofac's "Resolve" extension method with TypeMock

    - by Lockshopr
    I'm trying to mock an Autofac resolve, such as: using System; using Autofac; using TypeMock.ArrangeActAssert; class Program { static void Main(string[] args) { var inst = Isolate.Fake.Instance<IContainer>(); Isolate.Fake.StaticMethods(typeof(ResolutionExtensions), Members.ReturnNulls); Isolate.WhenCalled(() => inst.Resolve<IRubber>()).WillReturn(new BubbleGum()); Console.Out.WriteLine(inst.Resolve<IRubber>()); } } public interface IRubber {} public class BubbleGum : IRubber {} Coming from Moq, the syntax and exceptions from TypeMock confuse me a great deal. Having initially run this in a TestMethod, I kept getting an exception resembling "WhenCalled cannot be run without a complementing behavior". I tried defining behaviors for everyone and their mothers, but to no avail. Then I debug stepped through the test run, and saw that an actual exception was fired from Autofac: IRubber has not been registered. So it's obvious that the static Resolve function isn't being faked, and I can't get it to be faked, no matter how I go about hooking it up. Isolate.WhenCalled(() => ResolutionExtensions.Resolve<IRubber>(null)).WillReturn(new BubbleGum()); ... throws an exception from Autofac complaining that the IComponentContext cannot be null. Feeding it the presumably faked IContainer (or faking an IComponentContext instead) gets me back to the "IRubber not registered" error.

  • Why am I getting "Message sent to deallocated object" in Objective-C?

    - by Dave C
    I have several buttons on my app that are being created dynamically. They are all pointed at the button click event when pressed. When the button pressed method is called, the sender's tag (int value) is parsed into the controller's house ID. It works with one of the buttons — the first one created, to be specific — but the others throw the following error: -[CFNumber intValue]: message sent to deallocated instance 0xc4bb0ff0 I am not releasing these buttons anywhere in my code. I haven't set them to autorelease or anything like that. I'm just wondering why they are doing this on the click. The button click event: - (IBAction) ButtonClick: (id) sender { HouseholdViewController *controller = [[HouseholdViewController alloc] initWithNibName:@"HouseholdViewController" bundle:nil]; controller.delegate = self; controller.HouseID = [(NSInteger)[(UIButton *)sender tag] intValue]; //this line throws an error controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Where I am creating the buttons: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(MyLongInScreenCoords, MyLatInScreenCoords, 50, 50); UIImage *buttonImageNormal = [UIImage imageNamed:@"blue_pin.png"]; UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:50 topCapHeight:50]; [button setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal]; [self.view addSubview:button]; button.tag = [NSNumber numberWithInt:[[words objectAtIndex: i] intValue]]; ButtonPoints[CurrentHouseCount][0] = button; ButtonPoints[CurrentHouseCount][1] = [NSValue valueWithCGPoint:CGPointMake(MyActualLat, MyActualLong)]; [button addTarget:self action:@selector(ButtonClick:) forControlEvents:UIControlEventTouchUpInside]; CurrentHouseCount++;

  • UIWebview does not show up into UINavigationController

    - by Pato
    Hi I have a tabBar application. In the first tab, I have a navigation bar. In this navigation bar I have a table view. When the user clicks a cell of the table, it goes to another table view, and when the user clicks a cell in that table, it goes to a webview to open a web page. Basically, it goes fine until opening the webview. In the webview, viewDidLoad is called and seems to work properly. However, webViewDidStartLoad is never called and the web page never shows up. I am not using IB. I build the UITabBarController in the AppDelegate, where I also assign an instance of my UINavigationController for each tab. I call the webview from the second UITableViewController as follows: rssWebViewController = [[webViews objectAtIndex: indexPath.row] objectForKey:@"controller"]; [[self navigationController] pushViewController:rssWebViewController animated:YES]; I have checked that the navigationController is there and it seems just fine. The viewDidload of my webview is as follows: - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = self.storyUrl; NSURL *url = [NSURL URLWithString:urlAddress]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [[self rssWebView] setDelegate: self]; [[self view] addSubview:[self rssWebView]]; [rssWebView loadRequest:requestObj]; self.rssWebView.scalesPageToFit = YES; self.rssWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight); } The web view controller interface is defined as follows: @interface RSSWebViewController : UIViewController <UIWebViewDelegate>{ IBOutlet UIWebView *rssWebView; IBOutlet NSString *storyUrl; IBOutlet NSString *feedName; } @property (nonatomic, retain) IBOutlet UIWebView *rssWebView; @property (nonatomic, retain) IBOutlet NSString *storyUrl; @property (nonatomic, retain) IBOutlet NSString *feedName; @end Any help is greatly appreciated.

  • Can a stateless WCF service benefit from built-in database connection pooling?

    - by vladimir
    I understand that a typical .NET application that accesses a(n SQL Server) database doesn't have to do anything in particular in order to benefit from the connection pooling. Even if an application repeatedly opens and closes database connections, they do get pooled by the framework (assuming that things such as credentials do not change from call to call). My usage scenario seems to be a bit different. When my service gets instantiated, it opens a database connection once, does some work, closes the connection and returns the result. Then it gets torn down by the WCF, and the next incoming call creates a new instance of the service. In other words, my service gets instantiated per client call, as in [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]. The service accesses an SQL Server 2008 database. I'm using .NET framework 3.5 SP1. Does the connection pooling still work in this scenario, or I need to roll my own connection pool in form of a singleton or by some other means (IInstanceContextProvider?). I would rather avoid reinventing the wheel, if possible.

  • How do you protect a common resource using mutexes?

    - by Steve
    I have a common resource, which I want 1 and only 1 instance of my application (or it's COM API) to have access to at any time. I have tried to protect this resource using mutexes, but when multiple threads of a host dotnet application try to access the COM object, the mutex doesn't seem to be released. This is the code I have used to protect my resource. repeat Mutex := CreateMutex(nil, True, PChar('Connections')); until (Mutex <> 0) and (GetLastError <> ERROR_ALREADY_EXISTS); try //use resource here! finally CloseHandle(Mutex); end; If I run the threads simultaneously, the first thread get's through (obviously, being the first one to create the mutex), but subsequent threads are caught in the repeat loop. If I run each thread at 5 second intervals, then all is ok. I suspect I'm not using mutexes correctly here, but I have found very little documentation about how to do this. Any ideas?

  • Hierarchy / Flyweight / Instancing Problem in Python

    - by Dan
    Here is the problem I am trying to solve, (I have simplified the actual problem, but this should give you all the relevant information). I have a hierarchy like so: 1.A 1.B 1.C 2.A 3.D 4.B 5.F (This is hard to illustrate - each number is the parent, each letter is the child). Creating an instance of the 'letter' objects is expensive (IO, database costs, etc), so should only be done once. The hierarchy needs to be easy to navigate. Children in the hierarchy need to have just one parent. Modifying the contents of the letter objects should be possible directly from the objects in the hierarchy. There needs to be a central store containing all of the 'letter' objects (and only those in the hierarchy). 'letter' and 'number' objects need to be possible to create from a constructor (such as Letter(**kwargs) ). It is perfectably acceptable to expect that when a letter changes from the hierarchy, all other letters will respect the same change. Hope this isn't too abstract to illustrate the problem. What would be the best way of solving this? (Then I'll post my solution) Here's an example script: one = Number('one') a = Letter('a') one.addChild(a) two = Number('two') a = Letter('a') two.addChild(a) for child in one: child.method1() for child in two: print '%s' % child.method2()

  • Correct way of setting a custom FileInfo class to an Iterator

    - by Gordon
    I am trying to set a custom class to an Iterator through the setInfoClass method: Use this method to set a custom class which will be used when getFileInfo and getPathInfo are called. The class name passed to this method must be derived from SplFileInfo. My class is like this (simplified example): class MyFileInfo extends SplFileInfo { public $props = array( 'foo' => '1', 'bar' => '2' ); } The iterator code is this: $rit = new RecursiveIteratorIterator( new RecursiveDirectoryIterator('/some/file/path/'), RecursiveIteratorIterator::SELF_FIRST); Since RecursiveDirectoryIterator is by inheritance through DirectoryIterator also an SplFileInfo object, it provides the setInfoClass method (it's not listed in the manual, but reflection shows it's there). Thus I can do: $rit->getInnerIterator()->setInfoClass('MyFileInfo'); All good up to here, but when iterating over the directory with foreach($rit as $file) { var_dump( $file ); } I get the following weird result object(MyFileInfo)#4 (3) { ["props"]=>UNKNOWN:0 ["pathName":"SplFileInfo":private]=>string(49) "/some/file/path/someFile.txt" ["fileName":"SplFileInfo":private]=>string(25) "someFile.txt" } So while MyFileInfo is picked up, I cannot access it's properties. If I add custom methods, I can invoke them fine, but any properties are UNKNOWN. If I don't set the info class to the iterator, but to the SplFileInfo object (like shown in the example in the manual), it will give the same UNKNOWN result: foreach($rit as $file) { // $file is a SplFileInfo instance $file->setInfoClass('MyFileInfo'); var_dump( $file->getFileInfo() ); } However, it will work when I do foreach($rit as $file) { $file = new MyFileInfo($file); var_dump( $file ); } Unfortunately, the code I a want to use this in is somewhat more complicated and stacks some more iterators. Creating the MyFileInfo class like this is not an option. So, does anyone know how to get this working or why PHP behaves this weird? Thanks.

  • Can any linux API or tool watch for any change in any folder below e.g. /SharedRoot or do I have to

    - by Simon B.
    I have a folder with ~10 000 subfolders. Can any linux API or tool watch for any change in any folder below e.g. /SharedRoot or do I have to setup inotify for each folder? (i.e. I loose if I want to do this for 10k+ folders). I guess yes, since I've already seen examples of this inefficient method, for instance http://twistedmatrix.com/trac/browser/trunk/twisted/internet/inotify.py?rev=28866#L345 My problem: I need to keep folders time-sorted with most recently active "project" up top. When a file changes, each folder above that file should update its last-modified timestamp to match the file. Delays are ok. Opening a file (typically MS Excel) and closing again, its file date can jump up and then down again. For this reason I need to wait until after a file is closed, then queue the folder of that file for checking, and only a while later do I go and look for the newest file in its folder, since the filedate of the triggering file could already be back-dated to its original timestamp by Excel or similar programs. Also in case several files from same folder are used/created, it makes sense to buffer timestamping of that folders' parents to at least get a bunch of updates collapsed into one delayed update. I'm looking for a linux solution. I have some code that can be run on a windows server, most of the queing functionality is here: http://github.com/sesam/FolderdateFollowsFiles/blob/master/FolderdateFollowsFiles/Follower.vb Available API:s The relative of inotify on windows, ReadDirectoryChangesW, can watch a folder and its whole subtree; see bWatchSubtree on http://msdn.microsoft.com/en-us/library/aa365465(VS.85).aspx Samba? Patching samba source is a possibility, but perhaps there are already hooks available? Other possibilities, like client side (various windows versions) and spying on file activities in order to update folders recursively?

  • Every subsequent call to an Axis webservice fails

    I've been having a strange issue with an Axis webservice which is called through the https protocol. Basically, when an invocation is made, the call goes through just fine. If the call is made again, the web service fails, returning me with the following message: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <soapenv:Fault> <faultcode>soapenv:Server.userException</faultcode> <faultstring>org.xml.sax.SAXParseException: Unexpected end of file after null</faultstring> <detail> <ns1:hostname xmlns:ns1="http://xml.apache.org/axis/">f0s0</ns1:hostname> </detail> </soapenv:Fault> </soapenv:Body> </soapenv:Envelope> When tested locally (through http), the service works perfectly fine. Has anyone encountered an issue like this before? Any help is appreciated.

  • How to access a superclass's class attributes in Python?

    - by Brecht Machiels
    Have a look at the following code: class A(object): defaults = {'a': 1} def __getattr__(self, name): print('A.__getattr__') return self.get_default(name) @classmethod def get_default(cls, name): # some debug output print('A.get_default({}) - {}'.format(name, cls)) try: print(super(cls, cls).defaults) # as expected except AttributeError: #except for the base object class, of course pass # the actual function body try: return cls.defaults[name] except KeyError: return super(cls, cls).get_default(name) # infinite recursion #return cls.__mro__[1].get_default(name) # this works, though class B(A): defaults = {'b': 2} class C(B): defaults = {'c': 3} c = C() print('c.a =', c.a) I have a hierarchy of classes each with its own dictionary containing some default values. If an instance of a class doesn't have a particular attribute, a default value for it should be returned instead. If no default value for the attribute is contained in the current class's defaults dictionary, the superclass's defaults dictionary should be searched. I'm trying to implement this using the recursive class method get_default. The program gets stuck in an infinite recursion, unfortunately. My understanding of super() is obviously lacking. By accessing __mro__, I can get it to work properly though, but I'm not sure this is a proper solution. I have the feeling the answer is somewhere in this article, but I haven't been able to find it yet. Perhaps I need to resort to using a metaclass?

    I have a third party usb device, that when plugged into a Windows machine, is recognized as a serial device and assigned to the COM 4 port. I can communicate with the device just like I would with a device connected via a serial port. For instance, I can write "abc" serially to the device via the USB connection. I have been searching for a way to do a similar thing in Android. If I try the Usb Host method, and use a UsbManager to open the UsbDevice, I can get one interface, with 2 endpoints. I have tried sending control messages using the method in UsbDeviceConnection, but the method returns -1 for everything (though I don't know what I should use for the parameters of that method). Is there a way to get an OutputStream that I can write to that will send bytes to the USB device? Right now I am looking at recompiling the kernel to include a virtual COM port driver and write some native code to be able to do this. Thanks! Edit: I am using the FTDI serial to USB converter circuit. Is this compatible with Android?

  • How to save highlighting to a database

    - by vman
    Hi I am trying to highlight a part of the text on my website. This highlighted text will be saved for the specific user in a database and when the document is opened again it will show the previously highlighted text. I assumed I would be using javascript to highlight the text but I cannot seem to find a way to pinpoint where the word is that I am highlighting. function getSelText() { var txt = ''; if (window.getSelection) { txt = window.getSelection(); } else if (document.getSelection) { txt = document.getSelection(); } else if (document.selection) { txt = document.selection.createRange().text; } else return ""; return txt; } I am using that to get the selection but I cannot figure out where the selection is in the text. The biggest annoyance is when I have duplicates within the line or text so if I were to use search then I would find the first instance and not the one I was looking for. So the question is : How do you pinpoint a word or a selection in the entire document?

  • Using bitwise operators on > 32 bit integers

    - by dqhendricks
    I am using bitwise operations in order to represent many access control flags within one integer. ADMIN_ACCESS = 1; EDIT_ACCOUNT_ACCESS = 2; EDIT_ORDER_ACCESS = 4; var myAccess = 3; // ie: ( ADMIN_ACCESS | EDIT_ACCOUNT_ACCESS ) if ( myAccess & EDIT_ACCOUNT_ACCESS ) { // check for correct access // allow for editing of account } Most of this is occurring on the PHP side of my project. There is one piece however where Javascript is used to join several access flags using | when saving someone's access level. This works fine to a point. I have found that once an integer (flag) gets too large ( 32bit), it no longer works correctly with bitwise operators in Javascript. For instance: alert( 4294967296 | 1 ); // equals 1, but should equal 4294967297 I am trying to find a workaround for this so that I do not have to limit my number of access control flags to 32. Each access control flag is two times the previous control flag so that each control flag will not interfere with other control flags. dec(4) = bin(100) dec(8) = bin(1000) dec(16) = bin(10000) I have noticed that when adding two of these flags together with a simple +, it seems to come out with the same answer as a bitwise or operation, but am having trouble wrapping my head around whether this is a simple substitution, or if there might be problems with doing this. Can anyone comment on the validity of this workaround? Example: (4294967296 | 262144 | 524288) == (4294967296 + 262144 + 524288)

  • Finding the left-most and right-most points of a list. std::find_if the right way to go?

    - by Tom
    Hi, I have a list of Point objects, (each one with x,y properties) and would like to find the left-most and right-most points. I've been trying to do it with find_if, but i'm not sure its the way to go, because i can't seem to pass a comparator instance. Is find_if the way to go? Seems not. So, is there an algorithm in <algorithm> to achieve this? Thanks in advance. #include <iostream> #include <list> #include <algorithm> using namespace std; typedef struct Point{ float x; float y; } Point; bool left(Point& p1,Point& p2) { return p1.x < p2.x; } int main(){ Point p1 ={-1,0}; Point p2 ={1,0}; Point p3 ={5,0}; Point p4 ={7,0}; list <Point> points; points.push_back(p1); points.push_back(p2); points.push_back(p3); points.push_back(p4); //Should return an interator to p1. find_if(points.begin(),points.end(),left); return 0; }
