let's i'm in middle of proof , have hypotheses these: a : nat b : nat c : nat h : somepred b and definition of somepred says: definition somepred (p:nat) (q:nat) : prop := forall (x : nat), p(x, p, q). how apply h c , p(c, a, b) ? the answer is: specialize h c.

as title of question? what's difference? if write: char *cp = "a"; cout << (cp == "a") << endl; or: string str = "a"; cout << (str == "a") << endl; they same , return true. if write: char *cp = ""; cout << (cp == "\0") << endl; it returns false. but: string str = ""; cout << (str == "\0") << endl; it returns true. i thought should same pointer , array perspective. turn out different. what's subtle difference between them? , how should write char array represent empty string? ok, what's above line might unclear said might "a compiler optimization". what want this: char *cp = "abcd"; can give me array this: ['a', 'b', 'c', 'd', '\0']. wondering how can use similar syntax array this: ['\0']. because tried: char *cp = ""; and seems not r

i have syntax tree, saved in text file in "lisp-style", open , closed brackets show relations. want delete leaves. example, have " (det the)" want become " det". i'm not expert of regex, wonder how handle behaviour in more complex structure, nested brackets. example of tree (in file in 1 row, indented simpler visualization): (s (np i) (vp (vp (v shot) (np (det an) (n elephant))) (pp (p in) (np (det my) (n pajamas))))) i have like: (s np (vp (vp v (np det n)) (pp p (np det n)))) something this? re.sub("\((\w*) (\w*)\)", r"\1", t) where t variable holding syntax tree. for unicode support, see comments below.

i hope not simplest question. need make simple regression (yes, simple one: y = + bx + epsilon). data frame such each column has 1 variable (and each column has 20 rows (observations)). problem first 10 columns y1 y10 , last 1 independent variable. so, have run 10 regressions, changing yi (i = 1,...10). example: y1 = + bx + epsilon y2 = + bx + epsilon ... y10 = + bx + epsilon (yi , x vectors (20 x 1), it's exercise) i can 1 one, thinking them in 1 command. not veteran in programming , thinking if dplyr me this. i looking suggestions. thank you. you can try lapply(d1[paste0('y',1:10)], function(y) lm(y~d1[,'x'])) where d1 dataset

okay i've been playing code partly better understanding of python, , partly scrape data web. part of want learn if using python multiprocessing , pool. i've got basics working, because wrote procedure single threaded first, , moved use pool multi-thread process, have both global variables, , calls globally defined functions. i'm guessing both of these both bad, searching web, things seem complicated fast or don't answer questions. can confirm firstly global variables bad, , lead problems, me makes sense because 2 threads access same variable @ same time, hence problems. secondly, if have globally defined function, sake of argument processes string , returns it, using standard string functions, okay call within pool process? multithreading , multiprocessing quite different when comes how variables , functions can accessed. separate processes (multiprocessing) have different memory spaces , therefore cannot access same (instances of) functions or variab

when trying code in php: $result = 4 << 29; var_dump($result); // int(2147483648) but in other languages, example in java or javascript -2147483648 . why? this depends on php version you're running. while ago there bug in 32-bit int math when comes overflows. has been solved in php 5.3.

because nshttpcookiestorage has awful limitations i'm implementing own , 1 of methods re-implement - (nsarray *)sortedcookiesusingdescriptors:(nsarray *)sortorder . gets array of nssortdescriptor s , applies surprise, results tests seems indicate these sort descriptors applied in case insensitive fashion. i couldn't find way apply nssortdescriptor s in case insensitive way other setting selectors :@selector(caseinsensitivecompare:) since property selector read only, best managed this: nsmutablearray *insensitivesortorder = [nsmutablearray array]; (nssortdescriptor* sorter in sortorder) { [insensitivesortorder addobject: [nssortdescriptor sortdescriptorwithkey: sorter.key ascending:sorter.ascending selector:@selector(caseinsensitivecompare:)]]; } is implementation correct? there better way achieve this? one thing worries me i'm ignoring comparator property of nssortdescriptor.

im trying start using vim once again, got dead-end. im using portuguese layout keyboard, , can't type curly brackets or @ symbol inside vim. anyone knows need change have them work normally? update: barton points out, should have provide more complete information, here goes: when type alt+2 (in keyboard it's how type @) 2 exponent symbol. for curly brackets type alt+shift+8 / 9, gives me { , }, in vim shows small quote symbol , © symbol. when run :abbreviate command "no abbreviation found". update2: i've noticed on iterm can type symbols in vim mode, not on vim gui's. thanks help. finally discovered causing problems: set macmeta it wasn't easy catch one.

this question has answer here: why try/catch block create new variable scope? 5 answers i have problem trying use try/catch in code. whenever try , return result; error "cannot resolve symbol 'result'". here code. public object remove(int index) { try{ object result = this.get(index); (int k = index; k < size-1; k++) items[k] = items[k + 1]; items[size] = null; size--; return result; }catch(arrayindexoutofboundsexception e){ system.out.println("exception occurred in 'remove' method."); return result; } } you have defined result variable within try block. if declare variable within {} braces variable avialble use within braces , wont available outside world. so resolve issue, like: object result = null; try { .... } catch ... { } return result

how execute code after returning result client? example: return ok("first"); after need send response websocket actor myactor.tell("second",null) main goal - need send message socket after sending response you can't directly, return statements ends action. if problem long rendering of template, can render first, send message , send pre-rendered result, like result res = ok("first"); myactor.tell("second",null); return res; if doesn't satisfy still, can use akka scheduler schedule message let's 1 second delay. (check akka's documentations details) finally can send content , message @ once within current result i.e. wrapping within json object, or adding message response header - of course if you're handling js on client side.
