• C++ smart pointer for non-object type?

  - by Brian

  Hi, I'm trying to use smart pointers such as auto_ptr, shared_ptr. However, I don't know how to use it in this situation. CvMemStorage *storage = cvCreateMemStorage(); ... use the pointer ... cvReleaseMemStorage(&storage); I'm not sure, but I think that the storage variable is just malloc'ed memory, not object. Is there a way to use the smart pointers for the storage variable? Thank you.

• WCF threading - non-responsive UI

  - by Sphynx

  Hi everyone. I'm trying to configure some WCF stuff. Currently, I have a server which allows remote users to download files, and client. In the server, I use a ServiceHost class. I assume it should be running on a separate thread, however, the server UI (WinForms) becomes locked when someone downloads a file. Is there a way to manage the WCF threading model? Thank you!

• exec() in BeanShell macro causes jEdit to hang when it returns non-zero exit code

  - by rossmeissl

  I have a jEdit BeanShell macro that runs my Markdown files through Maruku when I save them: if (buffer.getMode().toString().equals("markdown")) { cmd = "C:\\Ruby\\bin\\maruku.bat -o " + buffer.getDirectory() + buffer.getName().replaceAll("markdown$", "html") + " " + buffer.getPath(); exec(cmd); } This works great when the Markdown file is valid. But if I've made a mistake, jEdit just waits around forever for the exec() call to "succeed," which it never will. When this happens, I have to kill jEdit's javaw.exe process and run Maruku manually from the command line to discover the error, e.g.: E:\bp\plan\supply_chain>maruku business_plan.markdown ___________________________________________________________________________ | Maruku tells you: +--------------------------------------------------------------------------- | Could not find ref_id = "17" for md_link(["17"],"17") | Available refs are [] +--------------------------------------------------------------------------- !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/errors_management.rb:49:in `maruku_error' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:716:in `to_html_link' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:970:in `send' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:970:in `array_to_html' !C:/Ruby/lib/ruby/gems/1.8/gems/maruku-0.6.0/lib/maruku/output/to_html.rb:961:in `each' \___________________________________________________________________________ Not creating a link for ref_id = "17". Then I restart jEdit, fix the error, and re-save the file, at which point the macro succeeds. How can I make my macro more resilient to either die helpfully (display Maruku's error output) or, at the very least, die silently so I don't have to kill jEdit?

• QApplication In Non-Main Thread

  - by Boatzart

  I need to exec() a QApplication in a thread that is not main (my GUIs must be plugins that can be dynamically loaded and unloaded at runtime, so I have no access to the main thread). Does anyone know of a (relatively) painless way to hack around Qt's restriction against starting QApplication outside of main? I'm developing in Linux with Qt4 in C++ using gcc4.3.4.

• remove non-UTF-8 characters from xml with declared encoding=utf-8 - Java

  - by St Nietzke

  I have to handle this scenario in Java: I'm getting a request in XML form from a client with declared encoding=utf-8. Unfortunately it may contain not utf-8 characters and there is a requirement to remove these characters from the xml on my side (legacy). Let's consider an example where this invalid XML contains £ (pound). 1) I get xml as java String with £ in it (I don't have access to interface right now, but I probably get xml as a java String). Can I use replaceAll(£, "") to get rid of this character? Any potential issues? 2) I get xml as an array of bytes - how to handle this operation safely in that case?

• Java NullPointerException when traversing a non-null recordset

  - by Tim

  Hello again - I am running a query on Sybase ASE that produces a ResultSet that I then traverse and write the contents out to a file. Sometimes, this will throw a NullPointerException, stating that the ResultSet is null. However, it will do this after printing out one or two records. Other times, with the same exact input, I will receive no errors. I have been unable to consistently produce this error. The error message is pointing to a line: output.print(rs.getString(1)); It appears to happen when the query takes a little longer to run, for some reason. The recordset returns thus far have been very small (4 to 7 records). Sometimes I'll have to run the app 3 or 4 times, then the errors will just stop, as though the query was getting "warmed up". I've run the query manually and there doesn't appear to be any performance problems. Thanks again!

• Matching non-[a-zA-Z] characters in PHP regex

  - by Bill X

  I have some strings that need a-strippin': ÃœT: 9.996636,76.294363 Tons of long strings of location codes. A literal regex in PHP won't match them, IE $pattern = /ÃœT:/; echo preg_replace($pattern, "", $row['location']); Won't match/strip anything. (To know it's working, /T:/ does strip the last bit of that string). What's the encoding error going on here? Alternately, I would accept a concise way to take out just the numbers.

• Non-blocking MySQL updates with java?

  - by justkevin

  For a multiplayer game I'm working on I'd like to record events to the mysql database without blocking the game update thread so that if the database is busy or a table is locked the game doesn't stop running while it waits for a write. What's the best way to accomplish this? I'm using c3p0 to manage the database connection pool. My best idea so far is to add query update strings to a synchronized list with an independent thread checking the list every 100ms and executing the queries it finds there.

• Low-Hanging Fruit: Obfuscating non-critical values in JavaScript

  - by Piskvor

  I'm making an in-browser game of the type "guess what place/monument/etc. is in this satellite/aerial view", using Google Maps JS API v3. However, I need to protect against cheaters - you have to pass a google.maps.LatLng and a zoom level to the map constructor, which means a cheating user only needs to view source to get to this data. I am already unsetting every value I possibly can without breaking the map (such as center and the manipulation functions like setZoom()), and initializing the map in an anonymous function (so the object is not visible in global namespace). Now, this is of course in-browser, client-side, untrusted JavaScript; I've read much of the obfuscation tag and I'm not trying to make the script bullet-proof (it's just a game, after all). I only need to make the obfuscation reasonably hard against the 1337 Java5kryp7 haxz0rz - "kid sister encryption", as Bruce Schneier puts it. Anything harder than base64 encoding would deter most cheaters by eliminating the lowest-hanging fruit - if the cheater is smart and determined enough to use a JS debugger, he can bypass anything I can do (as I need to pass the value to Google Maps API in plaintext), but that's unlikely to happen on a mass scale (there will also be other, not-code-related ways to prevent cheating). I've tried various minimizers and obfuscators, but those will mostly deal with code - the values are still shown verbatim. TL;DR: I need to obfuscate three values in JavaScript. I'm not looking for bullet-proof armor, just a sneeze-guard. What should I use?

• AudioRecord problems with non-HTC devices

  - by Marc

  I'm having troubles using AudioRecord. An example using some of the code derived from the splmeter project: private static final int FREQUENCY = 8000; private static final int CHANNEL = AudioFormat.CHANNEL_CONFIGURATION_MONO; private static final int ENCODING = AudioFormat.ENCODING_PCM_16BIT; private int BUFFSIZE = 50; private AudioRecord recordInstance = null; ... android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_URGENT_AUDIO); recordInstance = new AudioRecord(MediaRecorder.AudioSource.MIC, FREQUENCY, CHANNEL, ENCODING, 8000); recordInstance.startRecording(); short[] tempBuffer = new short[BUFFSIZE]; int retval = 0; while (this.isRunning) { for (int i = 0; i < BUFFSIZE - 1; i++) { tempBuffer[i] = 0; } retval = recordInstance.read(tempBuffer, 0, BUFFSIZE); ... // process the data } This works on the HTC Dream and the HTC Magic perfectly without any log warnings/errors, but causes problems on the emulators and Nexus One device. On the Nexus one, it simply never returns useful data. I cannot provide any other useful information as I'm having a remote friend do the testing. On the emulators (Android 1.5, 2.1 and 2.2), I get weird errors from the AudioFlinger and Buffer overflows with the AudioRecordThread. I also get a major slowdown in UI responsiveness (even though the recording takes place in a separate thread than the UI). Is there something apparent that I'm doing incorrectly? Do I have to do anything special for the Nexus One hardware?

• Initial conditions with a non-linear ODE in Mathematica

  - by buggy

  Hi, I'm trying to use Mathematica's NDSolve[] to compute a geodesic along a sphere using the coupled ODE: x" - (x" . x) x = 0 The problem is that I can only enter initial conditions for x(0) and x'(0) and the solver is happy with the solution where x" = 0. The problem is that my geodesic on the sphere has the initial condition that x"(0) = -x(0), which I have no idea how to tell mathematica. If I add this as a condition, it says I'm adding True to the list of conditions. Here is my code: s1 = NDSolve[{x1''[t] - (x1[t] * x1''[t] + x2[t] * x2''[t] + x3[t]*x3''[t]) * x1[t] == 0, x2''[t] - (x1[t] * x1''[t] + x2[t] * x2''[t] + x3[t]*x3''[t]) * x2[t] == 0, x3''[t] - (x1[t] * x1''[t] + x2[t] * x2''[t] + x3[t]*x3''[t]) * x3[t] == 0, x1[0] == 1, x2[0] == 0, x3[0] == 0, x1'[0] == 0, x2'[0] == 0, x3'[0] == 1} , { x1, x2, x3}, {t, -1, 1}][[1]] I would like to modify this so that the initial acceleration is not zero but -x(0). Thanks

• Serialization of non-required fields in protobuf-net

  - by David Hedlund

  I have a working java client that is communicating with Google, through ProtoBuf serialized messages. I am currently trying to translate that client into C#. I have a .proto file where the parameter appId is an optional string. Its default value in the C# representation as generated by the protobuf-net library is an empty string, just as it is in the java representation of the same file. message AppsRequest { optional AppType appType = 1; optional string query = 2; optional string categoryId = 3; optional string appId = 4; optional bool withExtendedInfo = 6; } I find that when I explicitly set appId to "" in the java client, the client stops working (403 Bad Request from Google). When I explicitly set appId to null in the java client, everything works, but only because hasAppId is being set to false (I'm uncertain as to how that affects the serialization). In the C# client, I always get 403 responses. I don't see any logic behind the distinction between not setting a value, and setting the default value, that seems to make all the difference in the java client. Since the output is always a binary stream, I am not sure if the successful java messages are being serialized with an empty string, or not serialized at all. In the C# client, I've tried setting IsRequired to true on the ProtoMember attribute, to force them to serialize, and I've tried setting the default value to null, and explicitly set "", so I'm quite sure I've tried some configuration where the value is being serialized. I've also played around with ProtoBuf.ProtoIgnore and at some point, removing the appId parameter altogether, but I haven't been able to avoid the 403 errors in C#. I've tried manually copying the serialized string from java, and that resolved my issues, so I'm certain that the rest of the HTTP Request is working, and the error can be traced to the serialized object. My serialization is simply this: var clone = ProtoBuf.Serializer.DeepClone(request); MemoryStream ms = new MemoryStream(2000); ProtoBuf.Serializer.Serialize(ms, clone); var bytearr = ms.ToArray(); string encodedData = Convert.ToBase64String(bytearr); I'll admit to not being quite sure about what DeepClone does. I've tried both with and without it...

• R: Select subset of dataframe by non-unique ids

  - by amarillion

  Suppose I have a dataframe like this one: df <- data.frame (id = c("a", "b", "a", "c", "e", "d", "e"), n=1:7) and a vector with ids like this one: v <- c("a", "b") How can I select the rows of the dataframe that match the ids in v? I can't use the id column for rownames because they are not unique.

• How to import your own non-packaged Java classes in Jython

  - by thepandaatemyface

  I know in Jython you can do import java.util.Random as Random Random().nextInt() But if I have a class I wrote myself, how can I import it into Jython without putting the class itself in a package? If I have a testclass Test: public class Test { public void foo() { System.out.println("bar"); } } that's not inside a package. Can I even import that into jython by using something along the lines offrom Test import Test?

• ResourceFilterFactory and non-Path annotated Resources

  - by tousdan

  (I'm using Jersey 1.7) I am attempting to add a ResourceFilterFactory in my project to select which filters are used per method using annotations. The ResourceFilterFactory seems to be able to filters on Resources which are annotated with the Path annotation but it would seem that it does not attempt to generate filters for the methods of the SubResourceLocator of the resources that are called. @Path("a") public class A { //sub resource locator? @Path("b") public B getB() { return new B(); } @GET public void doGet() {} } public class B { @GET public void doOtherGet() { } @Path("c") public void doInner() { } } When ran, the Filter factory will only be called for the following: AbstractResourceMethod(A#doGet) AbstractSubResourceLocator(A#getB) When I expected it to be called for every method of the sub resource. I'm currently using the following options in my web.xml; <init-param> <param-name>com.sun.jersey.spi.container.ResourceFilters</param-name> <param-value>com.my.MyResourceFilterFactory</param-value> </init-param> <init-param> <param-name>com.sun.jersey.config.property.packages</param-name> <param-value>com.my.resources</param-value> </init-param> Is my understanding of the filter factory flawed?

• GNU Make - Dependencies on non program code

  - by Tim Post

  A requirement for a program I am writing is that it must be able to trust a configuration file. To accomplish this, I am using several kinds of hashing algorithms to generate a hash of the file at compile time, this produces a header with the hashes as constants. Dependencies for this are pretty straight forward, my program depends on config_hash.h, which has a target that produces it. The makefile looks something like this : config_hash.h: $(SH) genhash config/config_file.cfg > $(srcdir)/config_hash.h $(PROGRAM): config_hash.h $(PROGRAM_DEPS) $(CC) ... ... ... I'm using the -M option to gcc, which is great for dealing with dependencies. If my header changes, my program is rebuilt. My problem is, I need to be able to tell if the config file has changed, so that config_hash.h is re-generated. I'm not quite sure how explain that kind of dependency to GNU make. I've tried listing config/config_file.cfg as a dependency for config_hash.h, and providing a .PHONY target for config_file.cfg without success. Obviously, I can't rely on the -M switch to gcc to help me here, since the config file is not a part of any object code. Any suggestions? Unfortunately, I can't post much of the Makefile, or I would have just posted the whole thing.

• Reducing a set of non-unique elements via transformations

  - by Andrey Fedorov

  I have: 1) a "starting set" of not-necessarily-unique elements, e.x. { x, y, z, z }, 2) a set of transformations, e.x. (x,z) = y, (z,z) = z, x = z, y = x, and 3) a "target set" that I am trying to get by applying transformations to the starting set, e.x. { z }. I'd like to find an algorithm to generate the (possibly infinite) possible applications of the transformations to the starting set that result in the target set. For example: { x, y, z, z }, y => x { x, x, z, z }, x => z { z, x, z, z }, x => z { z, z, z, z }, (z, z) => z { z, z, z }, (z, z) => z { z, z }, (z, z) => z { z } This sounds like something that's probably an existing (named) problem, but I don't recognize it. Can anyone help me track it down, or suggest further reading on something similar?

• Internet Explorer not incrementing number for non-sibling <li> elements

  - by biagidp

  I've got some html that looks like this: <ol> <div> <li>one</li> </div> <div> <li>two</li> </div> <div> <li>three</li> </div> </ol> Which looks like this in Chrome/Firefox: 1. one 2. two 3. three But looks like this in IE: 1. one 1. two 1. three If I change the code so that the li element is the parent of the div element instead of the other way around (so that all the li elements are siblings) IE renders it correctly. Anyone know what causes this or if this is the intended working behavior of IE? Furthermore is one way technically more correct than the other? <div><li></li></div> VS. <li><div></div></li> Thanks, David

• Spring security oauth2 provider to secure non-spring api

  - by user1241320

  I'm trying to set up an oauth 2.0 provider that should "secure" our restful api using spring-security-oauth. Being a 'spring fan' i thought it could be the quicker solution. main point is this restful thingie is not a spring based webapp. boss says the oauth provider should be a separate application, but i'm starting to doubt that. (got this impression by reading spring-security-oauth) i'm also new here so haven't really got my hands into this other (jersey-powered) restul api (core of our business). any help/hint will be much appreciated.

• C++ threaded class design from non-threaded class

  - by macs

  I'm working on a library doing audio encoding/decoding. The encoder shall be able to use multiple cores (i.e. multiple threads, using boost library), if available. What i have right now is a class that performs all encoding-relevant operations. The next step i want to take is to make that class threaded. So i'm wondering how to do this. I thought about writing a thread-class, creating n threads for n cores and then calling the encoder with the appropriate arguments. But maybe this is an overkill and there is no need for another class, so i'm going to make use of the "user interface" for thread-creation. I hope there are any suggestions.
