as far get, getting max sal of each dept: select ename, sal, deptno emp out sal = ( select max(sal) emp inside out.deptno=inside.deptno ); this returns 4 results, want sum of 4 results, how do that? seems not work: select ename, sum(sal), deptno emp out group deptno, sal, ename having sum(sal) = ( select max(sal) emp inside out.deptno=inside.deptno ); it returning same result first query. select sum(max_sal) total_sum ( select deptno, max(sal) max_sal emp group deptno ) x to highest salary every department can group department , use max() highest. use subquery sum these up.

wanted clear few questions websocket. is possible stream videos server client , client server @ same time...something video calling? can server stream 2 videos single client @ time? regarding first question, yes can. there wrappers simplify task such binaryjs . as per second question, require little configuration. once bidirectional link between client , server established, client treat every incoming message part of same stream. separating or multiplexing 2 videos in same stream have carry mark client separate it. it better idea open new connection (with same server) stream second video.

with regards arduino eeprom when writing , reading eeprom devices asks transmission of following format: wire.begintransmission(addr); wire.write(highaddr); wire.write(lowaddr); wire.write(data); wire.endtransmission(); what high address , low address mean? why can not tell write byte @ address 4. why need prove high , low? it looks me using i2c, going make assumption , base answer off of it. perhaps should clarify eeprom using. the way i2c works can have 1 master (your arduino) communicate multiple slaves (your eeprom example) on same i2c bus. since possible have multiple slaves connected on same bus, i2c protocol requires specify slave device communicating with. wire.begintransmission(addr) does. selecting device wants initiate communication with. if want communicate eeprom need send address of eeprom (you should able find address in eeprom datasheet). next, need specify memory location inside eeprom want access. done using 2 bytes highaddr , lowaddr. if instan...
