is possible perform input , output recording in same file? i'm getting microphone.

i save audio input , output devices. example, user using headphones , speakers.

here's example of i'm using:

void start() {      audioformat format = new audioformat(44100, 16, 2, true, true);      dataline.info targetinfo = new dataline.info(targetdataline.class, format);      mixer.info[] minfolist = audiosystem.getmixerinfo();      dataline.info info = null;      vector<audioformat> taudioformatlist = getsupportedformats(targetdataline.class);      javafilelogger.logit(0, "for in mixers info");      (final mixer.info mi : minfolist) {         javafilelogger.logit(0, "mierinfo: " + mi.tostring());          mixer m = audiosystem.getmixer(mi);          javafilelogger.logit(0, "mierinfo: " + m.tostring());          try {              javafilelogger.logit(0, " try open mixer ");              m.open();             javafilelogger.logit(0, "for audioformat");              (audioformat f : taudioformatlist) {                 javafilelogger.logit(0, " format " + f.tostring());                  info = new dataline.info(targetdataline.class, f);                  if (audiosystem.islinesupported(info) && audiosystem.getmixer(mi).islinesupported(info)) {                      javafilelogger.logit(0, " suported ");                      final targetdataline tline = (targetdataline) audiosystem.getline(info);                      javafilelogger.logit(0, " line ");                      tline.open(f);                     tline.start();                      javafilelogger.logit(0, " cast ");                      final audioinputstream ais = new audioinputstream(tline);                      javafilelogger.logit(0, " passou cast ");                      final thread writer = new thread(new runnable() {                         public void run() {                              try {                                 thread.sleep(1000);                             } catch (exception e) {                             }                              final thread stopper = new thread(new runnable() {                                 public void run() {                                      javafilelogger.logit(0, " iniciou thread " + this.hashcode());                                      try {                                         thread.sleep(10000);                                     } catch (interruptedexception ex) {                                         ex.printstacktrace();                                     }                                      javafilelogger.logit(0, " escrevendo " + this.hashcode());                                      javafilelogger.logit(0, " jofando no arquivo " + this.hashcode());                                      try {                                         thread.sleep(record_time);                                     } catch (interruptedexception ex) {                                         ex.printstacktrace();                                     }                                      javafilelogger.logit(0, " terminou o sleep " + this.hashcode());                                      tline.stop();                                     tline.close();                                      javafilelogger.logit(0, "fechou line " + this.hashcode());                                      try {                                         ais.close();                                     } catch (ioexception ex) {                                         // logger.getlogger(audiocapture.class.getname()).log(level.severe, null, ex);                                     }                                      javafilelogger.logit(0, "fechou o arq  e fnalizou thread " + this.hashcode());                                  }                             });                              stopper.start();                              try {                                 audiosystem.write(ais, filetype, new file("c:/s4/recordaudio_"+stopper.hashcode()+".wav"));                             } catch (ioexception ex) {                                 javafilelogger.logit(0, "erro ao gravar " + this.hashcode());                             }                         }                     });                          writer.start();                  }             }          } catch (exception e) {             javafilelogger.logit(0, "falha na identificação mixer " + e.getmessage());         }     }

neo4j - finding mutual friends in a cypher statement starting with three or more persons -

i trying build cypher statement neo4j know 2-n starting nodes name , need find node (if any) can reached of starting nodes. at first tought similar "mutual friend" situation handled (start1)-[*..2]->(main)<-[*..2]-(start2) in case have more 2 starting points around 6 know name. so puzzled how can include third, fourth , on node cypher able find commmon root amongst them. in above example neo4j website need path starting 'dilshad', 'becky' , 'cesar' check if have common friend (anders) excluding 'filipa' , 'emil' not friends of three. so far create statement programmatically looks like match (start1 {name:'person1'}), (start2 {name:'person2'}), (start3 {name: 'person3'}), (main) (start1)-[*..2]->(main) , (start2)-[*..2]->(main) , (start3)-[*..2]->(main) return distinct main but wondering if there more elegant / efficient way in cypher possibly use list of names parameter ...

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.
