i use tpanel or tgroupbox group form controls. now need draw straight line border of panel or groupbox. how do on lazarus? thanks in advance! note: technique must work on both linux , windows as optical line separator should use either tbevel component shape property set 1 of following values bstopline , bsbottomline , bsleftline or bsrightline depending on line need , resize smaller size (in case can use bstopline or bsbottomline , resize bevel vertically): or can use special component called tdividerbevel except single line adds optical divider caption:

i have 1 java method contains 5 different internal methods. performance improvement, want call these methods parallely. e.g. run method1, method2, ... method5 parallel using thread. private void getinformation() throws sqlexception, classnotfoundexception, namingexception { method1(); method2(); method3(); method4(); method5(); } but these 5 methods have different business logic. do this: for each method, create callable object wraps method. create executor (a fixed thread pool executor should fine). put callables in list , invoke them executor iterate on each future returned executor, wait thread complete, , results. here's simple example: public void testthread() { //create callable each method callable<void> callable1 = new callable<void>() { @override public void call() throws exception { method1(); return null; } }; callable<void> callable2 ...

according avl tree wiki the balance factor calculated follows: balancefactor = height(left-subtree) - height(right-subtree). each node checked, if balance factor remains −1, 0, or +1 no rotations necessary. however, in ocaml, seems uses balance factor of 2 let bal l x d r = let hl = match l empty -> 0 | node(_,_,_,_,h) -> h in let hr = match r empty -> 0 | node(_,_,_,_,h) -> h in if hl > hr + 2 begin match l empty -> invalid_arg "map.bal" | node(ll, lv, ld, lr, _) -> if height ll >= height lr create ll lv ld (create lr x d r) else begin match lr empty -> invalid_arg "map.bal" | node(lrl, lrv, lrd, lrr, _)-> create (create ll lv ld lrl) lrv lrd (create lrr x d r) end end else if hr > hl + 2 begin match r empty -> invalid_arg "map.bal...

in cases heap sort can used? know, heap sort has complexity of n× lg (n) . it's used far less quick , merge sort. when use heap sort , drawbacks? based on wikipedia article sorting algorithms , appears heapsort , mergesort have identical time complexity o(n log n) best, average , worst case. quicksort has disadvantage there worst case time complexity of o(n 2 ) (a) . mergesort has disadvantage memory complexity o(n) whereas heapsort o(1) . on other hand, mergesort stable sort , heapsort not. so, based on that, choose heapsort in preference mergesort if didn't care stability of sort, minimise memory usage. if stability required, choose mergesort. or, more correctly, if had huge amounts of data sort, , had code own algorithms it, i'd that. vast majority of cases, difference between 2 irrelevant, until data sets massive. in fact, i've used bubble sort in real production environments no other sort provided, because: it's incredibly easy w...

var s = "lala url(ok) tee hee url( oh ya ) kk"; s.match( /url(([^)]+))/g ); from 's' trying extract: ['ok', ' oh ya '] but, getting: ["url(ok", "url( oh ya "] i can iterate on list , remove 'url(', suspect regex-fu can remove too. in other language regex support lookbehind using regex (?<=url\()(([^)]+)) but unfortunately javascript regex doesn't support lookbehind this example , must iterate it. except don't realy need url word included.

is there anyway perform tilt action using uiautomator android? looked @ uiautomatorapi unable find direct method. there methods change device orientation. assume want. try: getuidevice().setorientationright(); getuidevice().setorientationleft(); getuidevice().setorientationnatural(); for more details on how use them can access link: auiautomator uidevice
