  • using php's libcurl to register user and upload file to server

    - by tunpishuang
    here is a site http://www.lyrkjsw.gov.cn that can let the registered user to upload file (e.g. images or office files) to the site. i want to register user and upload image to this site using libcurl binding with php. only registered user can upload image. so i use cookiejar stored in c:\cookie.txt after register and use c:\cookie.txt in uploadImg() function . register user is valid but failed to upload image , can anybody know is there any mistake of my code: <? /* options */ //the list url $expUrl='http://www.lyrkjsw.gov.cn/hbcms/user/list_resource.php'; //the user info to be registered $regUser='jiong'; $regPass='jiong'; $regMail='[email protected]'; $regUrl=str_replace('list_resource.php','register.php',$expUrl); // options for image upload $fileDir='@D:\img\b.jpg'; $fileTitle='aaaaaaaaaaaaa'; $fileDesc='aaaaaaaaaaaaadesc'; $uploadImgUrl=str_replace('list_resource.php','add_resource.php',$expUrl); /* register function */ function reg($regurl,$u,$p,$m) { $ch = curl_init(); $options=array( CURLOPT_URL=>$regurl, CURLOPT_RETURNTRANSFER=>true, CURLOPT_POST=>true, CURLOPT_POSTFIELDS=>'mod=register_now&next_url=index.php&addon_app=&referrer_id=&login_name='.$u.'&login_pass='.$p.'&confirm_login_pass='.$p.'&login_email='.$m.'&nickname=&gender=0&qq=&mobile=&telephone=&true_name=&website_name=&website_url=&my_question=&my_answer=', CURLOPT_COOKIESESSION=>true, CURLOPT_HEADER=>true, CURLOPT_COOKIEJAR=>'c:\cookie.txt' ); curl_setopt_array($ch,$options); $data = curl_exec($ch); if(strpos($data,'??')){ printf("register ok :)\n"); curl_close($ch); return true; }else{ printf("register failed:(\n"); curl_close($ch); return false; } } /* image uploading function */ function uploadImg($uploadimgurl,$filedir,$filetitle,$filedesc) { $ch = curl_init(); $options=array( CURLOPT_COOKIEFILE=>'c:\cookie.txt', CURLOPT_URL=>$uploadimgurl, CURLOPT_RETURNTRANSFER=>1, CURLOPT_POST=>1, CURLOPT_POSTFIELDS=>" 'MAX_FILE_SIZE'='33554432'& 'preview_area_id'='upload_file'& 'editor_area_id'='body'& 'js_function'=''& 'resource_id'=''& 'show_top_part'='no'& 'file_1'=$filedir& 'file_title_1'=$filetitle& 'file_desc_1'=$filedesc " ); curl_setopt_array($ch,$options); $data = curl_exec($ch); if(strpos($data,'??')){ printf("upload ok :)\n"); }else{ printf("upload failed :(\n"); } curl_close($ch); } if(reg($regUrl,$regUser,$regPass,$regMail) != false) { uploadImg($uploadImgUrl,$fileDir,$fileTitle,$fileDesc); } http://www.lyrkjsw.gov.cn/hbcms/user/list_resource.php (list file page) http://www.lyrkjsw.gov.cn/hbcms/user/register.php (register page) http://www.lyrkjsw.gov.cn/hbcms/user/add_resource.php (image uploading page)

  • problem in loading images from web

    - by Lynnooi
    hi, I am new in android and had developed an app which get images from the website and display it. I got it working in emulator but not in real phones. In some device, it will crash or take very long loading period. Can anyone please help me or guide me in improving it as i'm not sure whether the way i loads the images is correct or not. Here are the code i use to get the images from the web and display accordingly. if (xmlURL.length() != 0) { try { URL url = new URL(xmlURL); SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); /* Get the XMLReader of the SAXParser we created. */ XMLReader xr = sp.getXMLReader(); /* * Create a new ContentHandler and apply it to the * XML-Reader */ xr.setContentHandler(myExampleHandler); /* Parse the xml-data from our URL. */ xr.parse(new InputSource(url.openStream())); /* Parsing has finished. */ /* * Our ExampleHandler now provides the parsed data to * us. */ ParsedExampleDataSet parsedExampleDataSet = myExampleHandler.getParsedData(); } catch (Exception e) { } } if (s.equalsIgnoreCase("wallpapers")) { Context context = helloAndroid.this.getBaseContext(); for (int j = 0; j <= myExampleHandler.filenames.size() - 1; j++) { if (myExampleHandler.filenames.elementAt(j).toString() != null) { helloAndroid.this.ed = myExampleHandler.thumbs.elementAt(j) .toString(); if (helloAndroid.this.ed.length() != 0) { Drawable image = ImageOperations(context, helloAndroid.this.ed, "image.jpg"); file_info = myExampleHandler.filenames .elementAt(j).toString(); author = "\nby " + myExampleHandler.authors.elementAt(j) .toString(); switch (j + 1) { case 1: ImageView imgView1 = new ImageView(context); imgView1 = (ImageView) findViewById(R.id.image1); if (image.getIntrinsicHeight() > 0) { imgView1.setImageDrawable(image); } else imgView1 .setImageResource(R.drawable.empty_wallpaper); tv = (TextView) findViewById(R.id.filename1); tv.setText(file_info); tv = (TextView) findViewById(R.id.author1); tv.setText(author); imgView1 .setOnClickListener(new View.OnClickListener() { public void onClick(View view) { // Perform action on click Intent myIntent1 = new Intent( helloAndroid.this, galleryFile.class); Bundle b = new Bundle(); b.putString("fileID",myExampleHandler.fileid.elementAt(0).toString()); b.putString("page", "1"); b.putString("family", s); b.putString("fi",myExampleHandler.folder_id.elementAt(folder).toString()); b.putString("kw", keyword); myIntent1.putExtras(b); startActivityForResult( myIntent1, 0); } }); break; case 2: ImageView imgView2 = new ImageView(context); imgView2 = (ImageView) findViewById(R.id.image2); imgView2.setImageDrawable(image); tv = (TextView) findViewById(R.id.filename2); tv.setText(file_info); tv = (TextView) findViewById(R.id.author2); tv.setText(author); imgView2 .setOnClickListener(new View.OnClickListener() { public void onClick(View view) { // Perform action on click Intent myIntent1 = new Intent( helloAndroid.this, galleryFile.class); Bundle b = new Bundle(); b.putString("fileID",myExampleHandler.fileid.elementAt(1).toString()); b.putString("page", "1"); b.putString("family", s); b.putString("fi",myExampleHandler.folder_id.elementAt(folder).toString()); b.putString("kw", keyword); myIntent1.putExtras(b); startActivityForResult( myIntent1, 0); } }); break; case 3: //same code break; } } } } } private Drawable ImageOperations(Context ctx, String url, String saveFilename) { try { InputStream is = (InputStream) this.fetch(url); Drawable d = Drawable.createFromStream(is, "src"); return d; } catch (MalformedURLException e) { e.printStackTrace(); return null; } catch (IOException e) { e.printStackTrace(); return null; } } public Object fetch(String address) throws MalformedURLException, IOException { URL url = new URL(address); Object content = url.getContent(); return content; }

  • physics game programming box2d - orientating a turret-like object using torques

    - by egarcia
    This is a problem I hit when trying to implement a game using the LÖVE engine, which covers box2d with Lua scripting. The objective is simple: A turret-like object (seen from the top, on a 2D environment) needs to orientate itself so it points to a target. The turret is on the x,y coordinates, and the target is on tx, ty. We can consider that x,y are fixed, but tx, ty tend to vary from one instant to the other (i.e. they would be the mouse cursor). The turret has a rotor that can apply a rotational force (torque) on any given moment, clockwise or counter-clockwise. The magnitude of that force has an upper limit called maxTorque. The turret also has certain rotational inertia, which acts for angular movement the same way mass acts for linear movement. There's no friction of any kind, so the turret will keep spinning if it has an angular velocity. The turret has a small AI function that re-evaluates its orientation to verify that it points to the right direction, and activates the rotator. This happens every dt (~60 times per second). It looks like this right now: function Turret:update(dt) local x,y = self:getPositon() local tx,ty = self:getTarget() local maxTorque = self:getMaxTorque() -- max force of the turret rotor local inertia = self:getInertia() -- the rotational inertia local w = self:getAngularVelocity() -- current angular velocity of the turret local angle = self:getAngle() -- the angle the turret is facing currently -- the angle of the like that links the turret center with the target local targetAngle = math.atan2(oy-y,ox-x) local differenceAngle = _normalizeAngle(targetAngle - angle) if(differenceAngle <= math.pi) then -- counter-clockwise is the shortest path self:applyTorque(maxTorque) else -- clockwise is the shortest path self:applyTorque(-maxTorque) end end ... it fails. Let me explain with two illustrative situations: The turret "oscillates" around the targetAngle. If the target is "right behind the turret, just a little clock-wise", the turret will start applying clockwise torques, and keep applying them until the instant in which it surpasses the target angle. At that moment it will start applying torques on the opposite direction. But it will have gained a significant angular velocity, so it will keep going clockwise for some time... until the target will be "just behind, but a bit counter-clockwise". And it will start again. So the turret will oscillate or even go in round circles. I think that my turret should start applying torques in the "opposite direction of the shortest path" before it reaches the target angle (like a car braking before stopping). Intuitively, I think the turret should "start applying torques on the opposite direction of the shortest path when it is about half-way to the target objective". My intuition tells me that it has something to do with the angular velocity. And then there's the fact that the target is mobile - I don't know if I should take that into account somehow or just ignore it. How do I calculate when the turret must "start braking"?

  • .NET WinForms INotifyPropertyChanged updates all bindings when one is changed. Better way?

    - by Dave Welling
    In a windows forms application, a property change that triggers INotifyPropertyChanged, will result in the form reading EVERY property from my bound object, not just the property changed. (See example code below) This seems absurdly wasteful since the interface requires the name of the changing property. It is causing a lot of clocking in my app because some of the property getters require calculations to be performed. I'll likely need to implement some sort of logic in my getters to discard the unnecessary reads if there is no better way to do this. Am I missing something? Is there a better way? Don't say to use a different presentation technology please -- I am doing this on Windows Mobile (although the behavior happens on the full framework as well). Here's some toy code to demonstrate the problem. Clicking the button will result in BOTH textboxes being populated even though one property has changed. using System; using System.ComponentModel; using System.Drawing; using System.Windows.Forms; namespace Example { public class ExView : Form { private Presenter _presenter = new Presenter(); public ExView() { this.MinimizeBox = false; TextBox txt1 = new TextBox(); txt1.Parent = this; txt1.Location = new Point(1, 1); txt1.Width = this.ClientSize.Width - 10; txt1.DataBindings.Add("Text", _presenter, "SomeText1"); TextBox txt2 = new TextBox(); txt2.Parent = this; txt2.Location = new Point(1, 40); txt2.Width = this.ClientSize.Width - 10; txt2.DataBindings.Add("Text", _presenter, "SomeText2"); Button but = new Button(); but.Parent = this; but.Location = new Point(1, 80); but.Click +=new EventHandler(but_Click); } void but_Click(object sender, EventArgs e) { _presenter.SomeText1 = "some text 1"; } } public class Presenter : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; private string _SomeText1 = string.Empty; public string SomeText1 { get { return _SomeText1; } set { _SomeText1 = value; _SomeText2 = value; // <-- To demonstrate that both properties are read OnPropertyChanged("SomeText1"); } } private string _SomeText2 = string.Empty; public string SomeText2 { get { return _SomeText2; } set { _SomeText2 = value; OnPropertyChanged("SomeText2"); } } private void OnPropertyChanged(string PropertyName) { PropertyChangedEventHandler temp = PropertyChanged; if (temp != null) { temp(this, new PropertyChangedEventArgs(PropertyName)); } } } }

  • Reverse proxy for a REST web service using ADFS/AD and WebApi

    - by Kai Friis
    I need to implement a reverse proxy for a REST webservice behind a firewall. The reverse proxy should authenticate against an enterprise ADFS 2.0 server, preferably using claims in .net 4.5. The clients will be a mix of iOS, Android and web. I’m completely new to this topic; I’ve tried to implement the service as a REST service using WebApi, WIF and the new Identity and Access control in VS 2012, with no luck. I have also tried to look into Brock Allen’s Thinktecture.IdentityModel.45, however then my head was spinning so I didn’t see the difference between it and Windows Identity Foundation with the Identity and Access control. So I think I need to step back and get some advice on how to do this. There are several ways to this, as far as I understand it. In hardware. Set up our Citrix Netscaler as a reverse proxy. I have no idea how to do that, however if it’s a good solution I can always hire someone who knows… Do it in the webserver, like IIS. I haven’t tried it; do not know if it will work. Create a web service to do it. 3.1 Implement it as a SOAP service using WCF. As I understand it ADFS do not support REST so I have to use SOAP. The problem is mobile device do not like SOAP, neither do I… However if it’s the best way, I have to do it. 3.2 Use Azure Access Control Service. It might work, however the timing is not good. Our enterprise is considering several cloud options, and us jumping on the azure wagon on our own might not be the smartest thing to do right now. However if it is the only options, we can do it. I just prefer not to use it right now. Right now I feel there are too many options, and I do not know which one will work. If someone can point me in the right directions, which path to pursue, I would be very grateful.

  • angular, try to display object in ng-repeat fails

    - by Simone M
    i'm writing an mobile application in javascript with angularJS and ionicframework (last beta v.11), i create dinamically an object and want to display all objects inside in a ng-repeat. Why nr-repeat don't display anything?

  • Can GPU capabilities impact virtual machine performance?

    - by Dave White
    While this many not seem like a programming question directly, it impacts my development activities and so it seems like it belongs here. It seems that more and more developers are turning to virtual environments for development activities on their computers, SharePoint development being a prime example. Also, as a trainer, I have virtual training environments for all of the classes that I teach. I recently purchased a new Dell E6510 to travel around with. It has the i7 620M (Dual core, HyperThreaded cpu running at 2.66GHz) and 8 GB of memory. Reading the spec sheet, it sounded like it would be a great laptop to carry around and run virtual machines on. Getting the laptop though, I've been pretty disappointed with the user experience of developing in a virtual machine. Giving the Virtual Machine 4 GB of memory, it was slow and I could type complete sentences and watch the VM "catchup". My company has training laptops that we provide for our classes. They are Dell Precision M6400 Intel Core 2 Duo P8700 running at 2.54Ghz with 8 GB of memory and the experience on this laptops is night and day compared to the E6510. They are crisp and you barely aware that you are running in a virtual environment. Since the E6510 should be faster in all categories than the M6400, I couldn't understand why the new laptop was slower, so I did a component by component comparison and the only place where the E6510 is less performant than the M6400 is the graphics department. The M6400 is running a nVidia FX 2700m GPU and the E6510 is running a nVidia 3100M GPU. Looking at benchmarks of the two GPUs suggest that the FX 2700M is twice as fast as the 3100M. http://www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark-List.844.0.html 3100M = 111th (E6510) FX 2700m = 47th (Precision M6400) Radeon HD 5870 = 8th (Alienware) The host OS is Windows 7 64bit as is the guest OS, running in Virtual Box 3.1.8 with Guest Additions installed on the guest. The IDE being used in the virtual environment is VS 2010 Premium. So after that long setup, my question is: Is the GPU significantly impacting the virtual machine's performance or are there other factors that I'm not looking at that I can use to boost the vm's performance? Do we now have to consider GPU performance when purchasing laptops where we expect to use virtualized development environments? Thanks in advance. Cheers, Dave

  • Move options between multiple dropdown lists

    - by Martha
    We currently have a form with the standard multi-select functionality of "here are the available options, here are the selected options, here are some buttons to move stuff back and forth." However, the client now wants the ability to not just select certain items, but to also categorize them. For example, given a list of books, they want to not just select the ones they own, but also the ones they've read, the ones they would like to read, and the ones they've heard about. (All examples fictional.) Thankfully, a selected item can only be in one category at a time. I can find many examples of moving items between listboxes, but not a single one for moving items between multiple listboxes. To add to the complication, the form needs to have two sets of list+categories, e.g. a list of movies that need to be categorized in addition to the aforementioned books. An additional problem is that sorting between lists is all well and good in the javascript-enabled world, but I can't really think of a good fallback interface for, say, mobile browsers. Maybe a pseudo-listbox with radio buttons next to each item? The master list of items will in general be very long - over 100 items, certainly, possibly many more. Any given category will most likely contain one or two selected items, but the possibility exists for a category to have dozens of selected items, or zero selected items. As far as OS and stuff, the site is in classic asp (quit snickering!), the server-side code is VBScript, and so far we've avoided the various Javascript libraries by the simple expedient of almost never using client-side scripting. This one form for this one client is currently the big exception. Give 'em an inch and they want a mile... Oh, and I have to add: I suck at Javascript, or really at any C-descendant language. Curly braces give me hives. I'd really, really like something I can just copy & paste into my page, maybe tweak some variable names, and never look at it again. A girl can dream, can't she? :)

  • Web Services Primer for a WinForms Developer?

    - by Unicorns
    I've been writing client/server applications with Winforms for about six years now, but I have yet to venture into the web space (neither ASP.NET nor web services). Given the direction that the job market has been heading for some time and the fact that I have a basic curiosity, I'd like to get involved with writing web services, but I don't know where to start. I've read about various options (XML/SOAP vs. JSON, REST vs...well, actually I don't know what it's called, etc.), but I'm not sure what sort of criteria are in play when making the determination to use one or the other. Obviously, I'd like to leverage the tools that I have (Visual Studio, the .NET framework, etc.) without hamstringing myself into only targeting a particular audience (i.e. writing the service in such a way as to make it difficult to consume from a Windows Mobile/Android/iPhone client, for example). For the record, my plan--for now--is to use WCF for my web service development, but I'm open to using another .NET approach if that's advisable. I realize that this question is pretty open-ended so it may get closed, but here are some things I'm wondering: What are some things to consider when choosing the type of web service (REST, etc.) I intend to write? Is it possible (and, if so, feasible) to move from one approach to another? Can web services be written in an event-driven way? As I said I'm a Winforms developer, so I'm used to objects raising events for me to react to. For instance, if I have two clients connected to my service, is there a way for me to "push" information to one of them as a result of an action by the other? If this is possible, is this advisable or am I just not thinking about it correctly? What authentication mechanisms seem to work best for public-facing services? What about if I plan to have different types of OS'es and clients connecting to the service? Is there a generally accepted platform-agnostic approach? In the line of authentication, is this something that I should be doing myself (authenticating an managing sessions, etc.) or is this something should be handled at the framework level and I just define exactly how it should work? If that's the case, how do I tell who the requester has authenticated themselves as? I started writing an authentication mechanism (simple username/password combinations stored in the database and a corresponding session table with a GUID key) within my service and just requiring that key to be passed with every operation (other than logging in, of course), but I want to make sure that I'm not reinventing the wheel here. However, I also don't want to clutter up the server with a bunch of machine user accounts just to use Basic authentication. I'm also under the impression that Digest (and of course Windows) authentication requires a machine (or AD) user account.

    Hi, I'm trying to write a simple Python script for my mobile phone to periodically load a web page using urrlib2. In fact I don't really care about the server response, I'd only like to pass some values in the URL to the PHP. The problem is that Python for S60 uses the old 2.5.4 Python core, which seems to have a memory leak in the urrlib2 module. As I read there's seems to be such problems in every type of network communications as well. This bug have been reported here a couple of years ago, while some workarounds were posted as well. I've tried everything I could find on that page, and with the help of Google, but my phone still runs out of memory after ~70 page loads. Strangely the Garbege Collector does not seem to make any difference either, except making my script much slower. It is said that, that the newer (3.1) core solves this issue, but unfortunately I can't wait a year (or more) for the S60 port to come. here's how my script looks after adding every little trick I've found: import urrlib2, httplib, gc while(true): url = "http://something.com/foo.php?parameter=" + value f = urllib2.urlopen(url) f.read(1) f.fp._sock.recv=None # hacky avoidance f.close() del f gc.collect() Any suggestions, how to make it work forever without getting the "cannot allocate memory" error? Thanks for advance, cheers, b_m update: I've managed to connect 92 times before it ran out of memory, but It's still not good enough. update2: Tried the socket method as suggested earlier, this is the second best (wrong) solution so far: class UpdateSocketThread(threading.Thread): def run(self): global data while 1: url = "/foo.php?parameter=%d"%data s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(('something.com', 80)) s.send('GET '+url+' HTTP/1.0\r\n\r\n') s.close() sleep(1) I tried the little tricks, from above too. The thread closes after ~50 uploads (the phone has 50MB of memory left, obviously the Python shell has not.) UPDATE: I think I'm getting closer to the solution! I tried sending multiple data without closing and reopening the socket. This may be the key since this method will only leave one open file descriptor. The problem is: import socket s=socket.socket(socket.AF_INET, socket.SOCK_STREAM) socket.connect(("something.com", 80)) socket.send("test") #returns 4 (sent bytes, which is cool) socket.send("test") #4 socket.send("test") #4 socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns the number of sent bytes, ok socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns 0 on the phone, error on Windows7* socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns 0 on the phone, error on Windows7* socket.send("test") #returns 0, strange... *: error message: 10053, software caused connection abort Why can't I send multiple messages??

    I am using eclipse with android sdk 3.2 I have some problems to make my broadcast receiver working when the connection is lost. first I have checked the type of network to make sure I understand well : ConnectivityManager manager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE); boolean is3g = manager.getNetworkInfo( ConnectivityManager.TYPE_MOBILE) .isConnectedOrConnecting(); boolean isWifi = manager.getNetworkInfo( ConnectivityManager.TYPE_WIFI) .isConnectedOrConnecting(); NetworkInfo info = manager.getActiveNetworkInfo(); if (info != null) Toast.makeText(getApplicationContext(), info.getTypeName(), Toast.LENGTH_LONG).show(); else Toast.makeText(getApplicationContext(), "Pas de connexion", Toast.LENGTH_LONG).show(); if (!is3g) Log.i("Network Listener", "DISCONNECTED"); else Log.i("Network Listener", "CONNECTED"); == this is a mobile network, I'm connected Then I press F8 or I make : telnet localhost 5554 gsm data off to stop the connection Here is my dynamic broadcast receiver in an activity : public class ActivityA extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.query); this.registerReceiver(this.networkStateReceiver, new IntentFilter( ConnectivityManager.CONNECTIVITY_ACTION)); } BroadcastReceiver networkStateReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { ConnectivityManager connMgr = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = connMgr.getActiveNetworkInfo(); //i have tried several things : State networkState = networkInfo.getState(); // if (networkState.compareTo(State.DISCONNECTED) == 0) ... if (networkInfo != null && networkInfo.isConnected()) { Toast.makeText(getApplicationContext(), "CONNECTED", Toast.LENGTH_LONG).show(); Log.i("Network Listener", "Connected"); } else { Toast.makeText(getApplicationContext(), "DISCONNECTED", Toast.LENGTH_LONG).show(); Log.i("Network Listener", "Network Type Changed"); Intent offline = new Intent(AccountInfoActivity.this, OfflineWorkService.class); startService(offline); } }; My manifest : <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> The problem is : when the activityA is launched, my broadcast receive something and it displays "Connected"(Log) and my toast. When I turn off the connection manually, nothing happend. My service is not started, log message are not displayed, only toast messages work ... And even better, when I turn on the connection again (by pressing F8), I test again the type of connection, Toast messages are shown but this time Log messages don't work. Problems happend when I press F8. Anyway, I think I miss something with broadcast receivers, it's not totally clear. Please help me.

  • Moving a unit precisely along a path in x,y coordinates

    - by Adam Eberbach
    I am playing around with a strategy game where squads move around a map. Each turn a certain amount of movement is allocated to a squad and if the squad has a destination the points are applied each turn until the destination is reached. Actual distance is used so if a squad moves one position in the x or y direction it uses one point, but moving diagonally takes ~1.4 points. The squad maintains actual position as float which is then rounded to allow drawing the position on the map. The path is described by touching the squad and dragging to the end position then lifting the pen or finger. (I'm doing this on an iPhone now but Android/Qt/Windows Mobile would work the same) As the pointer moves x, y points are recorded so that the squad gains a list of intermediate destinations on the way to the final destination. I'm finding that the destinations are not evenly spaced but can be further apart depending on the speed of the pointer movement. Following the path is important because obstacles or terrain matter in this game. I'm not trying to remake Flight Control but that's a similar mechanic. Here's what I've been doing, but it just seems too complicated (pseudocode): getDestination() { - self.nextDestination = remove_from_array(destinations) - self.gradient = delta y to destination / delta x to destination - self.angle = atan(self.gradient) - self.cosAngle = cos(self.angle) - self.sinAngle = sin(self.angle) } move() { - get movement allocation for this turn - if self.nextDestination not valid - - getNextDestination() - while(nextDestination valid) && (movement allocation remains) { - - find xStep and yStep using movement allocation and sinAngle/cosAngle calculated for current self.nextDestination - - if current position + xStep crosses the destination - - - find x movement remaining after self.nextDestination reached - - - calculate remaining direct path movement allocation (xStep remaining / cosAngle) - - - make self.position equal to self.nextDestination - - else - - - apply xStep and yStep to current position - } - round squad's float coordinates to integer screen coordinates - draw squad image on map } That's simplified of course, stuff like sign needs to be tweaked to ensure movement is in the right direction. If trig is the best way to do it then lookup tables can be used or maybe it doesn't matter on modern devices like it used to. Suggestions for a better way to do it? an update - iPhone has zero issues with trig and tracking tens of positions and tracks implemented as described above and it draws in floats anyway. The Bresenham method is more efficient, trig is more precise. If I was to use integer Bresenham I would want to multiply by ten or so to maintain a little more positional accuracy to benefit collisions/terrain detection.

  • Issues in Ajax based applications

    - by Sinuhe
    I'm very interested in developing Ajax based applications. This is, loading almost all of the content of the application via XMLHttpRequest, instead of only some combos and widgets. But if I try to do this form scratch, soon I find some problems without an easy solution. I wonder if there is some framework (both client and server side) to deal with this issues. As far as I know, there isn't (but I've searched mainly in Java world). So I am seriously thinking of doing my own framework, at least for my projects. Therefore, in this question I ask for several things. First, the possible problems of an ajax based development. Then, I'm looking for some framework or utility in order to deal with them. Finally, if there is no framework available, what features must it have. Here are the issues I thought: 1 - JavaScript must be enabled. Security paranoia isn't the only problem: a lot of mobile devices couldn't use the application, too. 2 - Sometimes you need to update more than one DIV (e.g. main content, menu and breadcrumbs). 3 - Unknown response type: when you make an Ajax call, you set the callback function too, usually specifying if expected response is a javascript object or in which DIV put the result. But this fails when you get another type of response: for example when the session has expired and the user must log in again. 4 - Browser's refresh, back and forward buttons can be a real pain. User will expect different behaviors depending on the situation. 5 - When search engines indexes a site, only follow links. Thus, content load by Ajax won't "exist" for who doesn't know about it yet. 6 - Users can ask for open a link in a different window/tab. 7 - Address bar doesn't show the "real" page you are in. So, you can't copy the location and send it to a friend or bookmark the page. 8 - If you want to monetize the site, you can put some advertisings. As you don't refresh entire page and you want to change the ad after some time, you have to refresh only the DIV where the ad is. But this can violate the Terms and Conditions of your ad service. In fact, it can go against AdSense TOS. 9 - When you refresh an entire page, all JavaScript gets "cleaned". But in Ajax calls, all JavaScript objects will remain. 10 - You can't easily change your CSS properties.

  • Security review of an authenticated Diffie Hellman variant

    - by mtraut
    EDIT I'm still hoping for some advice on this, i tried to clarify my intentions... When i came upon device pairing in my mobile communication framework i studied a lot of papers on this topic and and also got some input from previous questions here. But, i didn't find a ready to implement protocol solution - so i invented a derivate and as i'm no crypto geek i'm not sure about the security caveats of the final solution: The main questions are Is SHA256 sufficient as a commit function? Is the addition of the shared secret as an authentication info in the commit string safe? What is the overall security of the 1024 bit group DH I assume at most 2^-24 bit probability of succesful MITM attack (because of 24 bit challenge). Is this plausible? What may be the most promising attack (besides ripping the device out off my numb, cold hands) This is the algorithm sketch For first time pairing, a solution proposed in "Key agreement in peer-to-peer wireless networks" (DH-SC) is implemented. I based it on a commitment derived from: A fix "UUID" for the communicating entity/role (128 bit, sent at protocol start, before commitment) The public DH key (192 bit private key, based on the 1024 bit Oakley group) A 24 bit random challenge Commit is computed using SHA256 c = sha256( UUID || DH pub || Chall) Both parties exchange this commitment, open and transfer the plain content of the above values. The 24 bit random is displayed to the user for manual authentication DH session key (128 bytes, see above) is computed When the user opts for persistent pairing, the session key is stored with the remote UUID as a shared secret Next time devices connect, commit is computed by additionally hashing the previous DH session key before the random challenge. For sure it is not transfered when opening. c = sha256( UUID || DH pub || DH sess || Chall) Now the user is not bothered authenticating when the local party can derive the same commitment using his own, stored previous DH session key. After succesful connection the new DH session key becomes the new shared secret. As this does not exactly fit the protocols i found so far (and as such their security proofs), i'd be very interested to get an opinion from some more crypto enabled guys here. BTW. i did read about the "EKE" protocol, but i'm not sure what the extra security level is.
