• How do I setup ASP.NET MVC 2 with MySQL?

  - by NovaJoe

  Okay, so I'm cheating and not actually a question, but instead making a flat-out post. I know that goes against the grain of Stack Overflow, but this is too valuable not to share. I'm assuming that you have Visual Studio Professional 2008 and access to an instance of MySQL server. This MAY work with VS2008 Web edition, but not at all sure. If you haven't, install MySQL Connector for .NET (6.2.2.0 at the time of this write-up) Optional: install MySQL GUI Tools If you haven't, install MVC 2 RTM, or better yet, use Microsoft's Web Platform Installer. Create an empty MySQL database. If you don't want to access your application with the MySQL root user account (insecure), create a user account and assign the appropriate privileges (outside the scope of this write-up). Create a new MVC 2 application in Visual Studio In the MVC 2 app, reference MySql.Web.dll. It will either be in your GAC, or in the folder that the MySQL Connector installer put it. Modify the connection strings portion of your web.config: <connectionStrings> <remove name="LocalMySqlServer"/> <add name="MySqlMembershipConnection" connectionString="Data Source=[MySql server host name];user id=[user];password=[password];database=[database name];" providerName="MySql.Data.MySqlClient"/> </connectionStrings> Modify the membership portion of your web.config: <membership defaultProvider="MySqlMembershipProvider"> <providers> <clear/> <add name="MySqlMembershipProvider" type="MySql.Web.Security.MySQLMembershipProvider, MySql.Web, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="MySqlMembershipConnection" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" autogenerateschema="true"/> </providers> </membership> Modify the role manager portion of your web.config: <roleManager enabled="true" defaultProvider="MySqlRoleProvider"> <providers> <clear /> <add connectionStringName="MySqlMembershipConnection" applicationName="/" name="MySqlRoleProvider" type="MySql.Web.Security.MySQLRoleProvider, MySql.Web, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" autogenerateschema="true"/> </providers> </roleManager> Modify the profile portion of your web.config: <profile> <providers> <clear/> <add type="MySql.Web.Security.MySQLProfileProvider, MySql.Web, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" name="MySqlProfileProvider" applicationName="/" connectionStringName="MySqlMembershipConnection" autogenerateschema="true"/> </providers> </profile> At this point, you ought to be able to run the app and have the default ASP.NET MVC 2 home page come up in your browser. However, it may be a better idea to first run the ASP.NET Web configuration Tool (in Visual Studio top menus: Project - ASP.NET Configuration). Once the tool launches, check out each of the tabs; no errors = all good. The configuration tool Nathan Bridgewater's blog was essential to getting this working. Kudos, Nathan. Look for the "Configuration Tool" heading half way down the page. The public key token on the MySql.web.dll that I've posted here ought not change any time soon. But in case you suspect a bad token string from copying and pasting or whatever, just use the Visual Studio command line to run: "sn -T [Path\to\your.dll]" in order to get the correct public key token. There you have it, ASP.NET MVC 2 running over MySQL. Cheers!

• C# WPF application is using too much memory while GC.GetTotalMemory() is low

  - by Dmitry

  I wrote little WPF application with 2 threads - main thread is GUI thread and another thread is worker. App has one WPF form with some controls. There is a button, allowing to select directory. After selecting directory, application scans for .jpg files in that directory and checks if their thumbnails are in hashtable. if they are, it does nothing. else it's adding their full filenames to queue for worker. Worker is taking filenames from this queue, loading JPEG images (using WPF's JpegBitmapDecoder and BitmapFrame), making thumbnails of them (using WPF's TransformedBitmap) and adding them to hashtable. Everything works fine, except memory consumption by this application when making thumbnails for big images (like 5000x5000 pixels). I've added textboxes on my form to show memory consumption (GC.GetTotalMemory() and Process.GetCurrentProcess().PrivateMemorySize64) and was very surprised, cuz GC.GetTotalMemory() stays close to 1-2 Mbytes, while private memory size constantly grows, especially when loading new image (~ +100Mb per image). Even after loading all images, making thumbnails of them and freeing original images, private memory size stays at ~700-800Mbytes. My VirtualBox is limited to 512Mb of physical memory and Windows in VirtualBox starts to swap alot to handle this huge memory consumption. I guess I'm doing something wrong, but I don't know how to investigate this problem, cuz according to GC, allocated memory size is very low. Attaching code of thumbnail loader class: class ThumbnailLoader { Hashtable thumbnails; Queue<string> taskqueue; EventWaitHandle wh; Thread[] workers; bool stop; object locker; int width, height, processed, added; public ThumbnailLoader() { int workercount,i; wh = new AutoResetEvent(false); thumbnails = new Hashtable(); taskqueue = new Queue<string>(); stop = false; locker = new object(); width = height = 64; processed = added = 0; workercount = Environment.ProcessorCount; workers=new Thread[workercount]; for (i = 0; i < workercount; i++) { workers[i] = new Thread(Worker); workers[i].IsBackground = true; workers[i].Priority = ThreadPriority.Highest; workers[i].Start(); } } public void SetThumbnailSize(int twidth, int theight) { width = twidth; height = theight; if (thumbnails.Count!=0) AddTask("#resethash"); } public void GetProgress(out int Added, out int Processed) { Added = added; Processed = processed; } private void AddTask(string filename) { lock(locker) { taskqueue.Enqueue(filename); wh.Set(); added++; } } private string NextTask() { lock(locker) { if (taskqueue.Count == 0) return null; else { processed++; return taskqueue.Dequeue(); } } } public static string FileNameToHash(string s) { return FormsAuthentication.HashPasswordForStoringInConfigFile(s, "MD5"); } public bool GetThumbnail(string filename,out BitmapFrame thumbnail) { string hash; hash = FileNameToHash(filename); if (thumbnails.ContainsKey(hash)) { thumbnail=(BitmapFrame)thumbnails[hash]; return true; } AddTask(filename); thumbnail = null; return false; } private BitmapFrame LoadThumbnail(string filename) { FileStream fs; JpegBitmapDecoder bd; BitmapFrame oldbf, bf; TransformedBitmap tb; double scale, dx, dy; fs = new FileStream(filename, FileMode.Open); bd = new JpegBitmapDecoder(fs, BitmapCreateOptions.None, BitmapCacheOption.OnLoad); oldbf = bd.Frames[0]; dx = (double)oldbf.Width / width; dy = (double)oldbf.Height / height; if (dx > dy) scale = 1 / dx; else scale = 1 / dy; tb = new TransformedBitmap(oldbf, new ScaleTransform(scale, scale)); bf = BitmapFrame.Create(tb); fs.Close(); oldbf = null; bd = null; GC.Collect(); return bf; } public void Dispose() { lock(locker) { stop = true; } AddTask(null); foreach (Thread worker in workers) { worker.Join(); } wh.Close(); } private void Worker() { string curtask,hash; while (!stop) { curtask = NextTask(); if (curtask == null) wh.WaitOne(); else { if (curtask == "#resethash") thumbnails.Clear(); else { hash = FileNameToHash(curtask); try { thumbnails[hash] = LoadThumbnail(curtask); } catch { thumbnails[hash] = null; } } } } } }

• Convert C++Builder AnsiString to std::string via boost::lexical_cast

  - by David Klein

  For a school assignment I have to implement a project in C++ using Borland C++ Builder. As the VCL uses AnsiString for all GUI Components I have to convert all of my std::strings to AnsiString for the sake of displaying. std::string inp = "Hello world!"; AnsiString outp(inp.c_str()); works of course but is a bit tedious to write and code duplication I want to avoid. As we use Boost in other contexts I decided to provide some helper functions go get boost::lexical_cast to work with AnsiString. Here is my implementation so far: std::istream& operator>>(std::istream& istr, AnsiString& str) { istr.exceptions(std::ios::badbit | std::ios::failbit | std::ios::eofbit); std::string s; std::getline(istr,s); str = AnsiString(s.c_str()); return istr; } In the beginning I got Access Violation after Access Violation but since I added the .exceptions() stuff the picture gets clearer. When the conversion is performed I get the following Exception: ios_base::eofbit set [Runtime Error/std::ios_base::failure] Does anyone have an idea how to fix it and can explain why the error occurs? My C++ experience is very limited. The conversion routine the other way round would be: std::ostream& operator<<(std::ostream& ostr,const AnsiString& str) { ostr << (str.c_str()); return ostr; } Maybe someone will spot an error here too :) With best regards! Edit: At the moment I'm using the edited version of Jem, it works in the beginning. After a while of using the programm the Borland Codeguard mentions some pointer arithmetic in already freed regions. Any ideas how this could be related? The Codeguard log (I'm using the german version, translations marked with stars): ------------------------------------------ Fehler 00080. 0x104230 (r) (Thread 0x07A4): Zeigerarithmetik in freigegebenem Speicher: 0x0241A238-0x0241A258. **(pointer arithmetic in freed region)** | d:\program files\borland\bds\4.0\include\dinkumware\sstream Zeile 126: | { // not first growth, adjust pointers | _Seekhigh = _Seekhigh - _Mysb::eback() + _Ptr; |> _Mysb::setp(_Mysb::pbase() - _Mysb::eback() + _Ptr, | _Mysb::pptr() - _Mysb::eback() + _Ptr, _Ptr + _Newsize); | if (_Mystate & _Noread) Aufrufhierarchie: **(stack-trace)** 0x00411731(=FOSChampion.exe:0x01:010731) d:\program files\borland\bds\4.0\include\dinkumware\sstream#126 0x00411183(=FOSChampion.exe:0x01:010183) d:\program files\borland\bds\4.0\include\dinkumware\streambuf#465 0x0040933D(=FOSChampion.exe:0x01:00833D) d:\program files\borland\bds\4.0\include\dinkumware\streambuf#151 0x00405988(=FOSChampion.exe:0x01:004988) d:\program files\borland\bds\4.0\include\dinkumware\ostream#679 0x00405759(=FOSChampion.exe:0x01:004759) D:\Projekte\Schule\foschamp\src\Server\Ansistringkonverter.h#31 0x004080C9(=FOSChampion.exe:0x01:0070C9) D:\Projekte\Schule\foschamp\lib\boost_1_34_1\boost/lexical_cast.hpp#151 Objekt (0x0241A238) [Größe: 32 Byte] war erstellt mit new **(Object was created with new)** | d:\program files\borland\bds\4.0\include\dinkumware\xmemory Zeile 28: | _Ty _FARQ *_Allocate(_SIZT _Count, _Ty _FARQ *) | { // allocate storage for _Count elements of type _Ty |> return ((_Ty _FARQ *)::operator new(_Count * sizeof (_Ty))); | } | Aufrufhierarchie: **(stack-trace)** 0x0040ED90(=FOSChampion.exe:0x01:00DD90) d:\program files\borland\bds\4.0\include\dinkumware\xmemory#28 0x0040E194(=FOSChampion.exe:0x01:00D194) d:\program files\borland\bds\4.0\include\dinkumware\xmemory#143 0x004115CF(=FOSChampion.exe:0x01:0105CF) d:\program files\borland\bds\4.0\include\dinkumware\sstream#105 0x00411183(=FOSChampion.exe:0x01:010183) d:\program files\borland\bds\4.0\include\dinkumware\streambuf#465 0x0040933D(=FOSChampion.exe:0x01:00833D) d:\program files\borland\bds\4.0\include\dinkumware\streambuf#151 0x00405988(=FOSChampion.exe:0x01:004988) d:\program files\borland\bds\4.0\include\dinkumware\ostream#679 Objekt (0x0241A238) war Gelöscht mit delete **(Object was deleted with delete)** | d:\program files\borland\bds\4.0\include\dinkumware\xmemory Zeile 138: | void deallocate(pointer _Ptr, size_type) | { // deallocate object at _Ptr, ignore size |> ::operator delete(_Ptr); | } | Aufrufhierarchie: **(stack-trace)** 0x004044C6(=FOSChampion.exe:0x01:0034C6) d:\program files\borland\bds\4.0\include\dinkumware\xmemory#138 0x00411628(=FOSChampion.exe:0x01:010628) d:\program files\borland\bds\4.0\include\dinkumware\sstream#111 0x00411183(=FOSChampion.exe:0x01:010183) d:\program files\borland\bds\4.0\include\dinkumware\streambuf#465 0x0040933D(=FOSChampion.exe:0x01:00833D) d:\program files\borland\bds\4.0\include\dinkumware\streambuf#151 0x00405988(=FOSChampion.exe:0x01:004988) d:\program files\borland\bds\4.0\include\dinkumware\ostream#679 0x00405759(=FOSChampion.exe:0x01:004759) D:\Projekte\Schule\foschamp\src\Server\Ansistringkonverter.h#31 ------------------------------------------ Ansistringkonverter.h is the file with the posted operators and line 31 is: std::ostream& operator<<(std::ostream& ostr,const AnsiString& str) { ostr << (str.c_str()); **(31)** return ostr; } Thanks for your help :)

• force close when assign onclick to button

  - by Lynnooi

  hi, i am very new in android development as well as in java. i had developed an application that gets an image url from a site and wanted to download it into the device and later on i would like to enable users to set it as wallpapers. however, i am met a problem when assigning onclick event to a button. Once i uncomment the line in red, it will pop up a box stating that the application was stopped unexpectedly. Can someone please help me with this? private ImageView imView = null; public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); try { /* Create a URL we want to load some xml-data from. */ URL url = new URL(xmlURL); /* Get a SAXParser from the SAXPArserFactory. */ 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 */ ExampleHandler myExampleHandler = new ExampleHandler(); 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(); /* Set the result to be displayed in our GUI. */ if (myExampleHandler.filenames != null) { a = a + "\n" + myExampleHandler.filenames + ", by " + myExampleHandler.authors + "\nhits: " + myExampleHandler.hits + " downloads"; this.ed = myExampleHandler.thumbs; this.imageURL = myExampleHandler.mediafiles; } } catch (Exception e) { a = e.getMessage(); } // get thumbnail Context context = this.getBaseContext(); if (ed.length() != 0) { Drawable image = ImageOperations(context, this.ed, "image.jpg"); ImageView imgView = new ImageView(context); imgView = (ImageView) findViewById(R.id.image1); imgView.setImageDrawable(image); } TextView tv = (TextView) findViewById(R.id.txt_name); tv.setText(a); Button bt3 = (Button) findViewById(R.id.get_imagebt); //bt3.setOnClickListener(getImageBtnOnClick); } OnClickListener getImageBtnOnClick = new OnClickListener() { public void onClick(View view) { downloadFile(imageURL); } }; void downloadFile(String fileUrl) { URL myFileUrl = null; try { myFileUrl = new URL(fileUrl); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { HttpURLConnection conn = (HttpURLConnection) myFileUrl .openConnection(); conn.setDoInput(true); conn.connect(); int length = conn.getContentLength(); InputStream is = conn.getInputStream(); bmImg = BitmapFactory.decodeStream(is); // this.imView.setImageBitmap(bmImg); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } 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; } Main.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/viewgroup"> <ImageView android:id="@+id/image1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" /> <ImageView android:id="@+id/image2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" /> <TextView android:id="@+id/txt_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" /> <Button id="@+id/get_imagebt" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="xxx Get an image" android:layout_gravity="center" /> <ImageView id="@+id/imview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" /> </LinearLayout>

• Unaccounted for database size

  - by Nazadus

  I currently have a database that is 20GB in size. I've run a few scripts which show on each tables size (and other incredibly useful information such as index stuff) and the biggest table is 1.1 million records which takes up 150MB of data. We have less than 50 tables most of which take up less than 1MB of data. After looking at the size of each table I don't understand why the database shouldn't be 1GB in size after a shrink. The amount of available free space that SqlServer (2005) reports is 0%. The log mode is set to simple. At this point my main concern is I feel like I have 19GB of unaccounted for used space. Is there something else I should look at? Normally I wouldn't care and would make this a passive research project except this particular situation calls for us to do a backup and restore on a weekly basis to put a copy on a satellite (which has no internet, so it must be done manually). I'd much rather copy 1GB (or even if it were down to 5GB!) than 20GB of data each week. sp_spaceused reports the following: Navigator-Production 19184.56 MB 3.02 MB And the second part of it: 19640872 KB 19512112 KB 108184 KB 20576 KB while I've found a few other scripts (such as the one from two of the server database size questions here, they all report the same information either found above or below). The script I am using is from SqlTeam. Here is the header info: * BigTables.sql * Bill Graziano (SQLTeam.com) * graz@<email removed> * v1.11 The top few tables show this (table, rows, reserved space, data, index, unused, etc): Activity 1143639 131 MB 89 MB 41768 KB 1648 KB 46% 1% EventAttendance 883261 90 MB 58 MB 32264 KB 328 KB 54% 0% Person 113437 31 MB 15 MB 15752 KB 912 KB 103% 3% HouseholdMember 113443 12 MB 6 MB 5224 KB 432 KB 82% 4% PostalAddress 48870 8 MB 6 MB 2200 KB 280 KB 36% 3% The rest of the tables are either the same in size or smaller. No more than 50 tables. Update 1: - All tables use unique identifiers. Usually an int incremented by 1 per row. I've also re-indexed everything. I ran the dbcc shrink command as well as updating the usage before and after. And over and over. An interesting thing I found is that when I restarted the server and confirmed no one was using it (and no maintenance procs are running, this is a very new application -- under a week old) and when I went to run the shrink, every now and then it would say something about data changed. Googling yielded too few useful answers with the obvious not applying (it was 1am and I disconnected everyone, so it seems impossible that was really the case). The data was migrated via C# code which basically looked at another server and brought things over. The quantity of deletes, at this point in time, are probably under 50k in rows. Even if those rows were the biggest rows, that wouldn't be more than 100M I would imagine. When I go to shrink via the GUI it reports 0% available to shrink, indicating that I've already gotten it as small as it thinks it can go. Update 2: sp_spaceused 'Activity' yields this (which seems right on the money): Activity 1143639 134488 KB 91072 KB 41768 KB 1648 KB Fill factor was 90. All primary keys are ints. Here is the command I used to 'updateusage': DBCC UPDATEUSAGE(0); Update 3: Per Edosoft's request: Image 111975 2407773 19262184 It appears as though the image table believes it's the 19GB portion. I don't understand what this means though. Is it really 19GB or is it misrepresented? Update 4: Talking to a co-worker and I found out that it's because of the pages, as someone else here has also state the potential for that. The only index on the image table is a clustered PK. Is this something I can fix or do I just have to deal with it? The regular script shows the Image table to be 6MB in size. Update 5: I think I'm just going to have to deal with it after further research. The images have been resized to be roughly 2-5KB each and on a normal file system doesn't consume much space but on SqlServer it seems to consume considerably more. The real answer, in the long run, will likely be separating that table in to another partition or something similar.

• checking player prefs from unity in xcode

  - by user313100

  I made a simple scene that has some GUI buttons in Unity. When you press a button it will set a player preference to 1. I have a button for facebook, twitter and a store. In XCode, when the value hits 1, it switches to a new window with facebook, twitter or the store. My problem is that when I try and retrieve the player preferences in XCode, they always come up as null. To compound my confusion, my code seems to respond to the switch to 1 and it switches to the new window when the value hits 1. Any ideas why it manages to switch to the other window and why I am getting null values? - (void) applicationDidFinishLaunching:(UIApplication*)application { printf_console("-> applicationDidFinishLaunching()\n"); NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setInteger:0 forKey:@"Store"]; [userDefaults setInteger:0 forKey:@"Facebook"]; [userDefaults setInteger:0 forKey:@"Twitter"]; _storeWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; _facebookWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; _twitterWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; viewControllerSK = [[SKViewController alloc]initWithNibName:@"SKViewController" bundle:nil]; viewControllerFacebook = [[xutils_exampleViewController alloc]initWithNibName:@"FacebookViewController" bundle:nil]; viewControllerTwitter = [[xutils_exampleViewController2 alloc]initWithNibName:@"TwitterViewController" bundle:nil]; [_storeWindow addSubview:viewControllerSK.view]; [_facebookWindow addSubview:viewControllerFacebook.view]; [_twitterWindow addSubview:viewControllerTwitter.view]; [SKStoreManager sharedManager]; [self startUnity:application]; } - (void) applicationDidBecomeActive:(UIApplication*)application { printf_console("-> applicationDidBecomeActive()\n"); if (gDidResignActive == true) { UnitySetAudioSessionActive(true); UnityPause(false); } gDidResignActive = false; [self newTimer]; } - (void) applicationWillResignActive:(UIApplication*)application { printf_console("-> applicationDidResignActive()\n"); UnitySetAudioSessionActive(false); UnityPause(true); gDidResignActive = true; } - (void) applicationDidReceiveMemoryWarning:(UIApplication*)application { printf_console("WARNING -> applicationDidReceiveMemoryWarning()\n"); } - (void) applicationWillTerminate:(UIApplication*)application { printf_console("-> applicationWillTerminate()\n"); UnityCleanup(); } -(void)newTimer { NSTimer *theTimer = [self getTimer]; [theTimer retain]; [[NSRunLoop currentRunLoop] addTimer: theTimer forMode: NSDefaultRunLoopMode]; } -(NSTimer *)getTimer { NSTimer *theTimer; theTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector: @selector(onLoop) userInfo:nil repeats:YES]; return [theTimer autorelease]; } -(void)onLoop { NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; //NSLog(@"FB: %@", [userDefaults integerForKey:@"Facebook"]); if ([userDefaults integerForKey:@"Store"] != 1 && [userDefaults integerForKey:@"Facebook"] != 1 && [userDefaults integerForKey:@"Twitter"] != 1) { UnityPause(FALSE); _window.hidden = NO; _storeWindow.hidden = YES; _facebookWindow.hidden = YES; _twitterWindow.hidden = YES; [_window makeKeyWindow]; } if ([userDefaults integerForKey:@"Store"] == 1) { UnityPause(TRUE); _storeWindow.hidden = NO; _window.hidden = YES; [_storeWindow makeKeyWindow]; } if ([userDefaults integerForKey:@"Facebook"] == 1) { UnityPause(TRUE); _facebookWindow.hidden = NO; _window.hidden = YES; [_facebookWindow makeKeyWindow]; } if ([userDefaults integerForKey:@"Twitter"] == 1) { UnityPause(TRUE); _twitterWindow.hidden = NO; _window.hidden = YES; [_twitterWindow makeKeyWindow]; } } -(void) dealloc { DestroySurface(&_surface); [_context release]; _context = nil; [_window release]; [_storeWindow release]; [_facebookWindow release]; [_twitterWindow release]; [viewControllerSK release]; [viewControllerFacebook release]; [viewControllerTwitter release]; [super dealloc]; }

• How to optimize method's that track metrics in 3rd party application?

  - by WulfgarPro

  Hi, I have two listboxes that keep updated lists of various objects roaming in a 3rd party application. When a user selects an object from a listbox, an event handler is fired, calling a method that gathers various metrics belonging to that object from the 3rd party application for displaying in a set of textboxes. This is slow! I am not sure how to optimize this functionality to facilitate greater speeds.. private void lsbUavs_SelectedIndexChanged(object sender, EventArgs e) { if (_ourSelectedUavFromListBox != null) { UtilStkScenario.ChangeUavColourOnScenario(_ourSelectedUavFromListBox.UavName, false);

From my knowledge, I cant really see any issues with the C#. Maybe it has to do with the methodology I'm using.. maybe some kind of caching mechanism is required - this is not natively available.

• What is causing the unusual high load average and IOwait?

  - by James

  I noticed on Tuesday night of last week, the load average went up sharply and it seemed abnormal since the traffic is small. Usually, the numbers usually average around .40 or lower and my server stuff (mysql, php and apache) are optimized.

• How to use sudo with WinSCP and ProFTPd?

  - by Gaia

  I need to run the SFTP fileserver binary as root, but direct root login is not allowed. In WinSCP, if I use "default" on SFTP server protocol option everything works as expected. Following the instructions to sudo in WinSCP, I tried using "sudo /usr/sbin/proftpd" (works on the command line without any prompts) but it brings up "Cannot initialize SFTP protocol.

• FreeBSD 8.0 - Macbook: Trying to Connect to Wireless

  - by Koroviev

  What Happened A few days ago I installed FreeBSD 8from USB to my Macbook (Core Duo, 13"). The first thing I wanted to do was get my GUI back. I'm new to FreeBSD and it's my first time off of mac or windows, so I had some learning to do. I tried to a make clean install of xorg with ports but it returned many "No address record" errors. I realised I hadn't configured network settings and then the fun started. I ran ifconfig and it found 5 devices: msk0, ath0, fwe0, fwip0, lo0. * ath0 was identified as media: IEEE 802.11 Wireless Ethernet autoselect so it was clear which one I needed. From what I gathered, there are 3 files and two processes involved here: /boot/loader.conf /etc/wpa_supplicant.conf /etc/rc.conf /etc/rc.d/netif wpa_supplicant (which is a part of the former too) I'm certain it's a big simplification, so correct me if I'm wrong here. What I Tried I configured /boot/loader.conf with the few basic settings, and I'm most sure that this file is okay. The other 2 were more puzzling. I tried to make a network package in wpa_supplicant.conf. I found the ssid of the router, but the security wasn't so easy. The routers configuration on security is set to "Auto", with no explanation given. Other options are there, but Auto is selected. Another laptop uses WEP to connect (it's Vista, so I don't know how to get any more info than that), but I never configured it to do it. There's a string labled "wireless key" on the bottom of the router which I entered to set it up a new machine on the network (Windows and Macs, so it was simplified). I never had to choose a security type and only learned about them by installing FreeBSD. So perhaps WEP is what "Auto" means, but I can't find any other evidence. wpa_supplicant.conf seemed to never be correctly configured. I always got errors related to it and WPA_supplicant doesn't work. It gave me "Can't disable/enable WPA in the driver" errors and more once when I enabled -d -d. This was when I was trying some suspect configurations in rc.conf though. Usually it does nothing except hijack the shell and print "CTRL-SCAN-EVENT-RESULT" every 10 seconds. I learned how to clone the ath0 device to a wlandev interface (wlan0). ath0 is associated to it and their connection seems to go smoothly. But the wlan0's connection to the network is the problem. I couldn't create this with rc.conf, I do something wrong and get ifconfig: create: bad value errors whenever it's parsed. I did it via the shell instead. What Now? I scanned with wlan0 today: ifconfig wlan0 list scan It shows my router, even my neighbour's router. It was a relief to finally get some feedback. So wlan0 is UP and detects the router, but it is always status: no carrier. It can't associate with it and I can't figure out why. Running /etc/rc.d/netif start returns almost the same result as ifconfig would. It shows lo0 and wlan0, and sometimes ath0. I still not sure what lo0 is doing. So; how do I associate with it? We can assume it's WEP security based on how the other laptop is setup. I'll give every relevant output here. After boot, with a blank rc.conf this is what ifconfig returns: msk0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=11a<TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4> ether 00:17:f2:29:89:3b media: Ethernet autoselect ath0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 2290 ether 00:16:cb:bb:fe:65 media: IEEE 802.11 Wireless Ethernet autoselect (autoselect) status: no carrier fwe0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 02:17:f2:60:ad:7e ch 1 dma -1 fwip0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 lladdr 0.17.f2.ff.fe.60.ad.7e.a.2.ff.fe.0.0.0.0 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x5 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 I run: ifconfig wlan0 create wlandev ath0 It returns: wlan0: bpf attached wlan0: bpf attached wlan0: Ethernet address: xx:xx:xx:xx:xx:xx Ifconfig now returns: msk0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=11a<TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4> ether 00:17:f2:29:89:3b media: Ethernet autoselect ath0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 2290 ether 00:16:cb:bb:fe:65 media: IEEE 802.11 Wireless Ethernet autoselect (autoselect) status: no carrier fwe0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 02:17:f2:60:ad:7e ch 1 dma -1 fwip0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 lladdr 0.17.f2.ff.fe.60.ad.7e.a.2.ff.fe.0.0.0.0 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x5 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 wlan0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:16:cb:bb:fe:65 media: IEEE 802.11 Wireless Ethernet autoselect (autoselect) status: no carrier ssid "" channel 1 (2412 Mhz 11b) regdomain 106 indoor ecm authmode OPEN privacy OFF txpower 20 bmiss 7 scanvalid 60 bgscan bgscanintvl 300 bgscanidle 250 roam:rssi 7 roam:rate 1 wme burst bintval 0 I run: ifconfig wlan0 up ifconfig wlan0 scan It finds my router and displays its details. I can feed it my routers details now, using: ifconfig wlan0 key value key value ... They show up in wlan0 when I run ifconfig, but it still doesn't associate. What details should I feed it, what exactly is needed? What, if anything, should I have in /etc/wpa_supplicant.conf (and if that psk is needed, is it most likely the string I mentioned above)? If I define the ssid in wpa_supplicant.conf, should I still feed it to wlan0? What process should I then use to associate it? 5 .How should I add these things to rc.conf so it will automatically do this at boot? A huge thank you in advance for any help you can give, I've spent hours crawling about the shell and I've learned quite a bit from it (I finally got the hang of vi too, from all that editing). But the sooner this is fixed, the better. *P.S. I was, and still am, wondering where the extra three devices come from (the wireless and wired were all I expected to find). lo0 is up at each boot and /etc/rc.d/netif, I have no idea what it is and can't find it in dmesg. Resources: /etc/loader.conf: Code: if_ath_load="YES" wlan_wep_load="YES" wlan_ccmp_load="YES" wlan_tkip_load="YES" /etc/wpa_supplicant.conf (I emptied it of everything unnecessary, because I was just causing errors) network={ ssid="BTVOYAGER2110-1C" } /etc/rc.conf has no network settings, I commented them out because of errors. There was my attempt to clone ath0 and feed it info, but I did if via the shell instead. I've included the output of dmesg as an attachment, in case it's useful. I'd include the boot text (which appears before login) but I don't know how to catch it into a text file. If it's needed and somebody tells me how, I will (actually, even if it's not needed, how can I view it to read?).

• Slow draw on some apps and dynamic clocks not working properly with ATI/AMD proprietary drivers

  - by Rakeka

  I've recently purchased a new computer (around July 2010) and I've been having some problems with proprietary video drivers on Linux. The hardware is: Video: ATI/AMD Radeon HD 5870 (XFX HD-587X-ZNFC); Motherboard: Asus P7P55D-E Deluxe; Processor: Intel i5 750; Memory: Kingston Hyperx KHX1600C8D3K2/4GX (2x - 8GB Total); Power Supply: XFX P1-750B-CAG9; There are no overclocks, not even the memories (they are at 1333mhz due processor memory controller limitation). The operational system is a homebrew Linux distribution with the following software: Architecture: x86_64 (multilib) Kernel: 2.6.35.10 Xorg: 7.5 Window Manager: wmii-3.9.2 Video Driver: ATI/AMD Catalyst 10.12 There are no desktop effects programs like compiz fusion or beryl. The problems: With ATI/AMD proprietary driver, some applications are with slow draw/redraw, and, the same applications make the driver to increase the card clocks to maximum (0% gpu activity, only the clocks are increased). I dunno exactly how to describe the slow draw but I'll list some applications and symptoms. xterm Flickers a lot when drawing continuous output; When I'm in a workspace with fullscreen xterm, The gpu load stays at 12% in idle, and, with smaller xterm, smaller GPU load. "aticonfig --odgc" output: Default Adapter - ATI Radeon HD 5800 Series Core (MHz) Memory (MHz) Current Clocks : 157 300 Current Peak : 850 1200 Configurable Peak Range : [600-900] [900-1300] GPU load : 12% "aticonfig --pplib-cmd 'get activity'" output: Current Activity is Core Clock: 157MHZ Memory Clock: 300MHZ VDDC: 950 Activity: 12 percent Performance Level: 0 Bus Speed: 5000 Bus Lanes: 16 Maximum Bus Lanes: 16 More examples: mplayer time info flickers on terminal; "find /" flickers a lot (It takes some time to stop with control-c. But, If I change the workspace or put some window upon it, just after the control-c, it stops instantly); "cat somefile" if the file is big (Xorg.0.log for example) it takes some time to display; vim and less (ex: find / | less) don't have much problems, just a little flicker when scrolling; mplayer (no gui) Slow reproduction and seek with -vo x11; Tearing with -vo xv; Time info flickers on terminal (xterm consequence); gvim A little slow draw when scrolling with page up/page down; Firefox Slow draw/redraw on some pages like www.boadica.com.br and sometimes on www.youtube.com with flash enable (never noticed on many pages); Corruptions when informative yellow boxes are showing and scroll the page (an gray box appears at the same place of the informative box); "Wallpaper" After minimizing a fullscreen window or changing to an empty workspace it takes some time to redraw wallpaper. "Video Card" The core and memory clocks are increased with the events described above and on other situations like change workspace (even without wallpaper), minimize, maximize or move a window; Idle clocks: Core: 157mhz, Memory: 300mhz Full clocks: Core: 850mhz, Memory: 1200mhz xpdf Painful slow scrolling; display (from ImageMagick) Slow menus and sometimes slow image redraw; Programs that I use and are apparently without problems: gimp; pidgin; mplayer (-vo gl, gl2); blender; unigine heaven (better fps than on Windows); doom3; tibia; penumbra overture; amnesia the dark descent (wine); diablo 2 (wine); No problems on Windows (Windows 7 Ultimate 64bit). And special note to this: Full desktop effects from Debian and Ubuntu gnome appearance cpanel don't cause ANY problems, even the core and memory clocks don't increase when change workspace, minimize, maximize or move a window. What I've tested: Unsuccessful tests: Tested all drivers versions since 10.6 (released approximately when I've installed the first slackware in this PC); Tested other video card - ATI/AMD Radeon HD 5570 (XFX HD-557X-ZHF2); Tested some options on xorg.conf and that I've found googling (some of these options are commented on my xorg.conf. I'll send the links at the end of post); Tested some patches like 107_fedora_dont_fill_bg_none.patch and xserver-xorg-backclear.patch from Arch Linux Catalyst page (https://wiki.archlinux.org/index.php/ATI_Catalyst); Tested other distros and software versions: Tested XORG-7.6 on my own distribution; Tested Debian Squeeze (testing - from 2010-12-20); Tested Ubuntu Marverick (10.10); Tested Slackware 13.1; Distros info: Architecture: i386 Debian and Ubuntu with all default software (kernel, gnome, xorg, drivers); Slackware with Catalyst from AMD page and default window managers like: fvwm, xfce, and my own build of wmii; Successful tests: Tested other video card (only on my homebrew distro) - NVIDIA Geforce 7300GS with driver 260.19.29; That didn't shown the slow draw problems, but that card is a bit obsolete, so, dunno if that lacks features like the dynamic clocks. I don't dispose of other video cards like nvidia g/gt/gts/gtx 200~400~500 or Radeon HD 3000/4000/6000 to make more tests. Tested other hardware: Video: ATI/AMD Radeon HD 5570 (XFX HD-557X-ZHF2); Motherboard: Intel DG31PR; Processor: Core 2 Duo E6750; Software for that hardware: Fresh install of same distros (except for the mine) with same program versions; That video card (HD 5570) were full time at the maximum clocks (something like 500/750, don't remember) in all the operational systems (Windows XP and Windows 7 too), but it didn't shown the same problems that I have here. I've googled a lot about common problems with ATI/AMD proprietary drivers for Linux and didn't find similar problems, except by the Firefox corruptions, that the solutions were to disable ATI Direct2DAccel and use XAA. With XAA the problems persists and the other applications like pidgin and rest of Firefox showed the same problems of slow draw/redraw. Open source Drivers: With open source drivers (xf86-video-ati-6.13.2) I hadn't the same slow draw problems, but, had other problems, that, for now, make it no viable solution. I'll not discuss it here because this is another line of problems and will confuse everything. If it happens to be the only solution, I'll make another thread to discuss it. Logs and Configs: kernel .config dmesg xorg package list xorg.conf Xorg.0.log

• firefox, opera 'The connection was reset' on few POST method calls on Windows and Ubuntu

  - by Gopalakrishnan Subramani

  my website works well with GET method, also few POST methods. Some pages with POST method doesn't work. Some pages with POST work. For example, login page uses POST that works fine. When I post the data on webpage, firefox says "Connecting..." and finally report connection timed out error. The same behavior happens with Opera as well. However Google Chrome works fine. At the server side, I use nginx 1.2.4 with HTTPS and uwsgi for python (flask framework) app. I use geotrust certificate. The same behavior happens with Windows 7 and Ubuntu 12.04 on firefox. I tried firefox in safemode, but no luck. Set auto-detect proxy settings. no luck. Cleared all cookies. no luck Anyone help me to fix this issue? I am posting ngix config. shame on me.

• Overriding the save() method of a model that uses django-mptt

  - by saturdayplace

  I've been using django-mptt in my project for a while now, it's fabulous. Recently, I've found a need to override a model's save() method that uses mptt, and I'm getting an error when I try to save a new instance of that model: Exception Type: ValueError at /admin/scrivener/page/add/ Exception Value: Cannot use None as a query value I'm assuming that this is a result of the fact that the instance hasn't been stuck into a tree yet, but I'm not sure how to go about fixing this. I added a comment about it onto a similar issue on the project's tracker, but I was hoping that someone here might be able to put me on the right track faster. Here's the traceback.

• Bluetooth RFCOMM / SDP connection to a RS232 adapter in android

  - by ThePosey

  Hello All, I am trying to use the Bluetooth Chat sample API app that google provides to connect to a bluetooth RS232 adapter hooked up to another device. Here is the app for reference: http://developer.android.com/resources/samples/BluetoothChat/index.html And here is the spec sheet for the RS232 connector just for reference: http://serialio.com/download/Docs/BlueSnap-guide-4.77_Commands.pdf Well the problem is that when I go to connect to the device with: mmSocket.connect(); (BluetoothSocket::connect()) I always get an IOException error thrown by the connect() method. When I do a toString on the exception I get "Service discovery failed". My question is mostly what are the cases that would cause an IOException to get thrown in the connect method? I know those are in the source somewhere but I don't know exactly how the java layer that you write apps in and the C/C++ layer that contains the actual stacks interface. I know that it uses the bluez bluetooth stack which is written in C/C++ but not sure how that ties into the java layer which is what I would think is throwing the exception. Any help on pointing me to where I can try to dissect this issue would be incredible. Also just to note I am able to pair with the RS232 adapter just fine but I am never able to actually connect. Here is the logcat output for more reference: I/ActivityManager( 1018): Displayed activity com.example.android.BluetoothChat/.DeviceListActivity: 326 ms (total 326 ms) E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) D/BluetoothChat( 1729): onActivityResult -1 D/BluetoothChatService( 1729): connect to: 00:06:66:03:0C:51 D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_CONNECTING E/BluetoothChat( 1729): + ON RESUME + I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_CONNECTING I/BluetoothChatService( 1729): BEGIN mConnectThread E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 I/BluetoothChatService( 1729): CONNECTION FAIL TOSTRING: java.io.IOException: Service discovery failed D/BluetoothChatService( 1729): setState() STATE_CONNECTING - STATE_LISTEN D/BluetoothChatService( 1729): start D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_LISTEN I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID I/NotificationService( 1018): enqueueToast pkg=com.example.android.BluetoothChat callback=android.app.ITransientNotification$Stub$Proxy@446327c8 duration=0 I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID The device I'm trying to connect to is the 00:06:66:03:0C:51 which I can scan for and apparently pair with just fine. The below is merged from a similar question which was successfully resolved by the selected answer here: How can one connect to an rfcomm device other than another phone in Android? The Android API provides examples of using listenUsingRfcommWithServiceRecord() to set up a socket and createRfcommSocketToServiceRecord() to connect to that socket. I'm trying to connect to an embedded device with a BlueSMiRF Gold chip. My working Python code (using the PyBluez library), which I'd like to port to Android, is as follows: sock = bluetooth.BluetoothSocket(proto=bluetooth.RFCOMM) sock.connect((device_addr, 1)) return sock.makefile() ...so the service to connect to is simply defined as channel 1, without any SDP lookup. As the only documented mechanism I see in the Android API does SDP lookup of a UUID, I'm slightly at a loss. Using "sdptool browse" from my Linux host comes up empty, so I surmise that the chip in question simply lacks SDP support.

• Optimizing Jaro-Winkler algorithm

  I have this code for Jaro-Winkler algorithm taken from this website. I need to run 150,000 times to get distance between differences. It takes a long time, as I run on an Android mobile device. Can it be optimized more? public class Jaro { /** * gets the similarity of the two strings using Jaro distance. * * @param string1 the first input string * @param string2 the second input string * @return a value between 0-1 of the similarity */ public float getSimilarity(final String string1, final String string2) { //get half the length of the string rounded up - (this is the distance used for acceptable transpositions) final int halflen = ((Math.min(string1.length(), string2.length())) / 2) + ((Math.min(string1.length(), string2.length())) % 2); //get common characters final StringBuffer common1 = getCommonCharacters(string1, string2, halflen); final StringBuffer common2 = getCommonCharacters(string2, string1, halflen); //check for zero in common if (common1.length() == 0 || common2.length() == 0) { return 0.0f; } //check for same length common strings returning 0.0f is not the same if (common1.length() != common2.length()) { return 0.0f; } //get the number of transpositions int transpositions = 0; int n=common1.length(); for (int i = 0; i < n; i++) { if (common1.charAt(i) != common2.charAt(i)) transpositions++; } transpositions /= 2.0f; //calculate jaro metric return (common1.length() / ((float) string1.length()) + common2.length() / ((float) string2.length()) + (common1.length() - transpositions) / ((float) common1.length())) / 3.0f; } /** * returns a string buffer of characters from string1 within string2 if they are of a given * distance seperation from the position in string1. * * @param string1 * @param string2 * @param distanceSep * @return a string buffer of characters from string1 within string2 if they are of a given * distance seperation from the position in string1 */ private static StringBuffer getCommonCharacters(final String string1, final String string2, final int distanceSep) { //create a return buffer of characters final StringBuffer returnCommons = new StringBuffer(); //create a copy of string2 for processing final StringBuffer copy = new StringBuffer(string2); //iterate over string1 int n=string1.length(); int m=string2.length(); for (int i = 0; i < n; i++) { final char ch = string1.charAt(i); //set boolean for quick loop exit if found boolean foundIt = false; //compare char with range of characters to either side for (int j = Math.max(0, i - distanceSep); !foundIt && j < Math.min(i + distanceSep, m - 1); j++) { //check if found if (copy.charAt(j) == ch) { foundIt = true; //append character found returnCommons.append(ch); //alter copied string2 for processing copy.setCharAt(j, (char)0); } } } return returnCommons; } } I mention that in the whole process I make just instance of the script, so only once jaro= new Jaro(); If you are going to test and need examples so not break the script, you will find it here, in another thread for python optimization.

I don't have time to read or digest long intricate discussions on theoretical concepts around NLP (or go get my PHD). That said, I have read a few and it's a damn interesting field. The problem is I need real world solutions, for real world products, in real world time frames. The problem I'm having is right now I'm not sure what the right questions are to ask to get started implementing. I believe this is mostly related to vocabulary. I'll read somewhere, a blog post, a forum post, a whitepaper, and it says, I'm doing flooping with the blargy blarg method, and I go google flooping and blargy blarg, and I get references to more obscurity. It seemingly never ends. So, my question is multiphased. First, more generally, how do I become passingly educated on this quickly? Just in time educated. I only need to know what I need to know to take the next step. I've spent 20 years writing code. Explain quick. I'll get it. (I mean provide a reference to something that explains quickly of course). I'm happy to read the right book, but I don't want to read a book where I read the chapter introduction that explains what floopy floop is and then skip over the rest of the chapter with examples of floopy flooping (because now I get what it is). I also don't want to read a book that goes into too much detail with theoretical underpinnings or history. For example, the Jurafsky book seems like way more than I need: http://www.amazon.com/gp/product/0131873210. But I will read it if this is the right book to read. (It's also dang expensive!) I need the root node of the expedited learning tree here, if you will. Point me in the right direction and I'll be quite grateful. I'm expecting quite a lot of firehose drinking - I just need the right firehose. Second, what I need to do is take a single sentence, with a very reduced vocabulary, and get a grammar tree (sorry if this is the wrong terminology) that I can do something with. I know I could easily write this command line input style in c in a more conventional manner, but I need it to be way better than that. But I don't need a chatterbot either. What I'm doing needs to live in a constrained environment. I can't use Python (unfortunately). I can't ship with gigabytes of corpuses. I need any libraries I use to be in c/c++. If I have to write this myself, I will. Hopefully, it will be achievable considering the reduced problem set. Maybe, probably, that's just naive. If so, let me know. :-) Thanks in advance - Mike
