public class bluetoothservice {     private static final string servicename = "btspp://localhost:"             // + new uuid("0000110100001000800000805f9b34f7", false).tostring()             // + new uuid("0000110100001000800000805f9b34f8", false).tostring()             + new uuid("0000110100001000800000805f9b34f9", false).tostring()             + ";name=servicename";     private streamconnectionnotifier m_service = null;     private listenerthread m_listenerthread;     private dataoutputstream m_outstream;      public bluetoothservice()     {         open();     }      public void open()     {         try         {             assert (m_service == null);             m_service = (streamconnectionnotifier) connector.open(servicename);         }         catch (ioexception e)         {             e.printstacktrace();         }     }      public void start()     {         try         {             streamconnection connection = (streamconnection) m_service                     .acceptandopen();             system.out.println("connected");              m_listenerthread = new listenerthread(connection);             thread listener = new thread(m_listenerthread);             listener.start();             m_outstream = new dataoutputstream(connection.openoutputstream());         }         catch (ioexception e)         {             // todo auto-generated catch block             e.printstacktrace();         }     }      public void send(string message)     {         assert (m_listenerthread != null);         try         {             m_outstream.writeutf(message);             m_outstream.flush();             system.out.println("sent: " + message);         }         catch (ioexception e)         {             // todo auto-generated catch block             e.printstacktrace();         }     }      public void close()     {         try         {             m_service.close();             m_listenerthread.stop();             m_listenerthread = null;             m_outstream.close();             m_outstream = null;             m_service = null;         }         catch (ioexception e)         {             e.printstacktrace();         }     } }  class listenerthread implements runnable {     private datainputstream m_instream;     private boolean m_isrunning;     public listenerthread(streamconnection connection)     {         try         {             this.m_instream = new datainputstream(connection.openinputstream());             m_isrunning = true;         }         catch (ioexception e)         {             // todo auto-generated catch block             e.printstacktrace();         }         ;     }      public void run()     {         while (m_isrunning)         {             try             {                 assert (m_instream != null);                 if (m_instream.available() > 0)                 {                     string message = m_instream.readutf();                     system.out.println("received command: " + message);                     commandmanager.getinstance().parse(message);                 }             }             catch (ioexception e)             {                 system.err.println(e.tostring());             }         }     }      public void stop()     {         m_isrunning = false;         try         {             m_instream.close();         }         catch (ioexception e)         {             // todo auto-generated catch block             e.printstacktrace();         }     } }

for restarting service do:

    bluetoothservice::close();     bluetoothservice::open();     bluetoothservice::start();

but seems cannot reconnect. maybe should create service different name?

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
