i have simple script trap 'echo exit' exit while true; sleep 1; done and behaves differently in different shells: $ bash tst.sh ^cexit $ dash tst.sh ^c $ zsh tst.sh ^c $ sh tst.sh ^cexit so i'm not sure how should operate , whether specified @ all. the exit trap isn't working same way in every shell. few examples: in dash , zsh it's triggered regular exit within script. in zsh, if trap signal quit execution, need restore default behaviour explicitly calling exit . i'd suggest catch signals , exit, should portable across shells: $ cat trap trap 'echo exit; exit' int term # , other signals while true; sleep 1; done $ bash trap ^cexit $ dash trap ^cexit $ zsh trap ^cexit $ ksh trap ^cexit $ mksh trap ^cexit $ busybox sh trap ^cexit

the simplest way create handle active excel sheets in .ahk script is: xl := comobjactive("excel.application") nonetheless, if 1 switches workbook, becomes new " currently active sheet " , autohotkey tries use methods sheets , cells on new workbook through com: of course scripts designed work specific sheets , cells don't work anymore on different workbook. do know how create com handles specific workbooks instead of active sheet? the goal should allow user loop between workbooks without xl object losing previous handle , going new one. example open excel workbook scratch , type 1234 in cell a1 of sheet named " sheet1 "; create new .ahk script following content: #persistent xl := comobjactive("excel.application") settimer, xlread, 5000 return xlread: { value := xl.sheets("sheets1").range("a1").value msgbox, %value% } return script above should display "1234" in message box every 5 secon...

i'm trying following code: double = double.max_value - (1000000000 * 100000000 * 1000000); system.out.println(a); however, result still 1.7976931348623157e308 (max value of double) can explain me? 1000000000 * 100000000 * 1000000 multiplication of 3 integers, results in overflow. even if avoid overflow writing : double = double.max_value - (1000000000.0 * 100000000.0 * 1000000.0); you still see no difference since number subtracting double.max_value negligible compared double.max_value (~1.797*10^308, 275 orders of magnitude larger trying subtract it).

i have following piece of code.i have confirm whether way how works..can provide explanation this object implicits { implicit class richseq[a](val xs:seq[a]) { def mapd[b](function:a => b):seq[b] = xs.map(function) } } this abstraction on map can use sequence. if import implicits.richseq can use methods on seq[a] convert seq[a] richseq[a]. import implicits.richseq._ val xs:seq[int] = seq(22,33) val output:seq[int] = xs.mapd(_+22) i want know how works because when use mapd on type seq[a] search implicit conversion seq[a] richseq[a].where find implicit conversion implicit class? does expand implicit class like: implicit def richseq[a](val xs:seq[a]) = new richseq(xs) i think might doing stuff inside.does ne1 know this? an implicit class shorthand for class foo(a: a) implicit def pimpmya(a: a) = new foo(a) you can annotate class implicit if constructor takes 1 non-implicit parameter. here's relevant doc can read more it: http://docs.scal...

i've encountered problem seems pretty basic , simple , can't figure out proper , elegant way how solve it. the situation is: there's player can move - let's upward. while moving can encounter obstacles - let's trees. , can bypass them using pretty simple algorithm one: if <the obstacle has free tile on right>: move_right() elif <the obstacle has free tile on left>: move_left() else: stop() well, works perfectly, there's drawback: if obstacle has free tiles both right , left can bypassed both sides, player bypasses right. it's pretty explainable, still not cool. the idea add variety , randomize somehow order in player checks availability of tiles if both free move not right, in random direction. , must admit cannot come idea how in simple , beautiful way. basically, solution should this... if random(0, 1) == 0: if <the obstacle has free tile on right>: move_right() elif <the obstacle has free tile on le...
