after recent change host has made, auto_increment columns incrementing two. after emailing host this, said: this sites located on our new load balanced shared platform. behaviour expected on new cluster. auto increment not affect performance or working of tables, , can still counts on tables , use incremented columns in same way. if check directly on database see these incrementing two. eventually behaviour applied our servers perform update on our entire platform. what know: saying right? in mind auto increment column should increment 1 , not two!! this going cause few issues older sites use generate order numbers etc. everything else have got continue work ok, bit annoying. disregarding specifics of host, if piece of code depends on auto increment going 1 one , not having holes, code wrong because never guarantee. the guarantees have column not have duplicates, , new rows have next sequence value column; last value + 1, not guaranteed - gu

so hosted website purpose of doing security-tests on it, created script in perl generate 60-72 mbps (info) being sent. noticed if run script multiple times simultaneously generate 150 mbps. how possible able achieve 150 mbps without need of running script multiple times? thank you! you want open multiple tcp connections. you either need use evented loop handle back-and-forth of keeping pipes full, or need use threads/processes. commented above, can use 'fork' make multiple copies of script, each 1 can make 1 tcp connection , keep connection full. that's simple solution. if want keep program single process, it's bit more work, still possible. if opening lot of connections, you'll want read this: http://www.kegel.com/c10k.html you might consider using faster language c or go, since using perl involve overhead. (i'd test first, maybe overhead negligible. test using tool curl send big file see if gets higher bandwidth perl program.)

this question has answer here: hashing password using crypt not work on login displays incorrect pass 2 answers i have registration page allows users insert password. hash password upon registration stored more securely in database. when user logs in same password, 2 hashes don't match , user cannot log in. this first time using hash , didn't behave expected: this hashing code on registration page: $salt =""; function cryptpass($input, $rounds = 9) { $salt = ""; $saltchars = array_merge(range('a','z'), range('a','z'), range('0','9')); for($i = 0; $i<22; $i++) { $salt .=$saltchars[array_rand($saltchars)]; } return crypt($input, sprintf('$2y$%02d$test$', $rounds) . $salt); } $hashedpass = cryptpass($pass1); echo $hashedpass; //****

i'm using qt5 on os x 10.8 , i'm creating application menu bar in qt creator. placing items quit or preferences in application menu works specifying menurole accordingly. however, since items need placed in menu , moved automatically qt application menu end empty menu items. according this empty items should hidden me not. what have this: file preferences <separator> quit preferences , quit , about correctly moved application menu. unfortunately file , about still shown. how can make qt hide them? after going project 10 months , 2 minor qt versions later, problem gone. installed qt 5.2 on os x 10.9 , app's menu expected.

well struggled problem lot. tried simple drag , drop operation, did in main form(the 1 operate main thread) , easy sounds. code this: protected override void onmousedown(mouseeventargs e) { dragdropeffects effectresult=dodragdrop("hello", dragdropeffects.copy); base.onmousedown(e); } i'm talking source code. don't care target. so, in main form code works fine , , when push mouse down, hold , move it, see sign of dragging (in case circle line on it). now in main thread i'm calling other thread , openning new form code showdialog() the problem start here, when put same code in new form, returns none effectresult variable , nothing cursor. i guess problem because of new thread, work async, how can fix it?

given following objective-c example, matter of style , ease of reading keep separate statements or bundle them one? there actual benefits of either? waste of memory declare individual variables? nsdictionary *thedict = [anobject methodtocreatedictionary]; nsarray *thevalues = [thedict allvalues]; nsstring *theresult = [thearray componentsjoinedbystring:@" "]; or nsstring *theresult = [[[anobject methodtocreatedictionary] thevalues] componentsjoinedbystring:@" "]; i take following consideration when declare separate variable: if might want see value in debugger. if accessing variable more once. if line long. there no practical difference between 2 approaches, however.
