is there way make query better removing repeated pattern of select in clause? best efficient way write query? using sqlite. select abs(avg(ravg1) - avg(ravg2)) (select avg(stars) ravg1 movie m join rating r on m.mid = r.mid group r.mid having year < 1980 ), (select avg(stars) ravg2 movie m join rating r on m.mid = r.mid group r.mid having year > 1980 ) if want difference in ratings years before , after 1980, can use conditional aggregation: select abs(avg(case when year < 1980 stars end) - avg(case when year > 1980 stars end) ) movie m join rating r on m.mid = r.mid;

to update table use this: update `table` set column = value column = value is there way update column value? example: table 'test' has 2 columns called 'one' , 'two'. i'll set them: 'one' 10, , 'two' 20, , wish update columm have value 10, variable, , can't know wich column is. thanks you'd have query table first: select * mytable col1 = 10 or col2 = 10 then, you'll need server-side code (like php, ruby, python, etc) determine column has needed value, , can build new update query based on that: update mytable set col1 = 20 however, can't think of scenario efficient way of managing data. may want reconsider how database designed.

i'm writing sanity-checking initializer should kill rails process in event properties not met. safest way abort production server's startup process in way? suppose extreme case running exit , i'm not sure if it's best approach. running on unicorn if matters. there 3 ways end ruby process: exit end process status 0 (success). exit! end status 1 (which seems appropriate case), , not run blocks defined using kernel#at_exit (which may or may not desirable you). abort end status 1, , will run kernel#at_exit blocks. can give string sent standard out. so abort best bet. unless have particular reason not run kernel#at_exit blocks want run them. since unicorn runs initializers once , forks processes after that, approach should fine. i'll add i'm guessing doing these checks @ "wrong" level -- if possible should check health of environment outside of context of rails. don't know situation, , realize quickness of solution mor...

how create lock lock different threads entering function? thread 1: thread 2: c thread 3: c thread 4: b thread 5: c thread 6: b "a", "b" ,"c" argument passed in thread when created. so when lock 1 lock x, threads of have "a" , "b" passed in cannot continue , thread of type "c" can enter critical section. or have make 6 different locks example? thank you! your requirement's vague, assuming want concurrent readers same "allowed letter", you'd better off using rwlock. (if want "control" thread setting of a, b or c allowed work, rather having a, b , c take on whenever no other "letter" running through controlled code, different (simpler) solution needed....) as first cut (so can "evolve" solution in easier-to-understand way), each thread: 1) acquires reader lock 2) if "allowed letter" variable differs letter, release reader lock , try writer lock ...

jpanel droppan = new jpanel (); droppan.setlayout (new flowlayout ()); bi1 = new imageicon (""); b1 = new jbutton (bi1); //b1.setborderpainted (false); b1.setborder (borderfactory.createemptyborder (2,3,2,3)); b1.setcontentareafilled (false); b1.setsize (100,38); //b1.setbounds(3,3,100,38); droppan.add(b1); b1.addmouselistener (this); add(droppan); this row of buttons code above snippet of first button. initially, first button has border unless click on button , button has border, if "transfers" if mean. what doing wrong? setborderpainted comment because if it's not in comment border still there this panel inside frame i "think" talking focus border used show button has focus... try using b1.setfocuspainted(false); instead for example... import java.awt.borderlayout; import java.awt.eventqueue; import java.awt.flowlayout; import javax.swing.borderfactory; import javax.swing.imageicon; import javax.swing.jbutton; import j...

from arduino, i'm writing multi-byte data serial serial.print("blah"), in objective-c, -serialport:didreceivedata: (provided orsserialport) gets data 1 byte @ time. occasionally, it'll grab 2 bytes @ once, never 4. expected? if so, how can make receive 4 bytes @ once? arduino: void loop() { serial.print("blah"); delay(1000); } obj-c: - (void)serialport:(orsserialport *)serialport didreceivedata:(nsdata *)data { nsstring *string = [[nsstring alloc] initwithdata:data encoding:nsutf8stringencoding]; nslog(@"%@",string); } setting breakpoint inside method shows data holds 1 byte. this normal, expected behavior. underlying serial hardware , software has no way of knowing how many bytes you're waiting for, or complete packet looks like, delivers data comes in. you'll have buffer data in objective-c code. fundamentally, pretty simple. create nsmutabledata can use buffer: @property (strong) nsmutabledata *i...

i've got context menu, , styled correctly resourcedictionary loaded xamlreader.load(). style key i'm using dynamicresource i've called stylebanner. in context menu have 1 menu item called skins, styled correctly save above dynamic resource stylebanner. menu-item has it's sub-menu-items data-bound itemssource in data context view model, , working correctly. my trouble child menu items not styled correctly. here working, not getting styled @ all: <window.contextmenu> <contextmenu datacontext="timershostviewmodel" name="timershostcontextmenu" style="{dynamicresource stylebanner}"> <menuitem name="skins" header="skins" itemssource="{binding source={staticresource timershostviewmodel}, path=skins}" style="{dynamicresource stylebanner}"> <menuitem.itemcontainerstyle> <style targettype="menuitem"> ...
