under delphi 2010 (and under d2009 also) default string type unicodestring. however if declare... const s :string = 'test'; ss :string[4] = 'test'; ... first string s if declared unicodestring , second 1 ss declared ansistring ! we can check this: sizeof(s[1]); return size 2 , sizeof(ss[1]) ; return size 1. if declare... var s :string; ss :string[4]; ... want ss unicodestring type. how can tell delphi 2010 both strings should unicodestring type? how else can declare ss holds 4 widechars? compiler not accept type declarations widestring[4] or unicodestring[4] . what purpose of 2 different compiler declarations same type name: string ? the answer lies in fact string[n] , shortstring , considered legacy type. embarcadero took decision not convert shortstring have support unicode. since long string introduced, if memory serves correctly, in delphi 2, seems reasonable decision me. if want fixed length arrays of widechar can...

it not possible create object directly calling constructor of abstract class. constructor of abstract class can called derived class. therefore seems me constructors of abstract class must either protected or package-private (the latter unusual cases of restricting use of constructor derived classes within package). yet java allows constructor of abstract class public . are there circumstances in useful declare constructor of abstract class public , rather protected or package-private? this not quite duplicate of question " abstract class constructor access modifier ": can declare constructor public ; want know whether there ever good reason so. seems me there not. see c# has similar peculiarity . the answer same java: there's no reason public constructor abstract class. i'd assume reason compiler doesn't complain simple didn't spend time covering since doesn't matter if it's public or protected.

i wrote answer first project euler question: add natural numbers below 1 thousand multiples of 3 or 5. the first thing came me was: (1 until 1000).filter(i => (i % 3 == 0 || % 5 == 0)).foldleft(0)(_ + _) but it's slow (it takes 125 ms), rewrote it, thinking of 'another way' versus 'the faster way' (1 until 1000).foldleft(0){ (total, x) => x match { case if (i % 3 == 0 || % 5 ==0) => + total // add case _ => total //skip } } this faster (only 2 ms). why? i'm guess second version uses range generator , doesn't manifest realized collection in way, doing in 1 pass, both faster , less memory. right? here code on ideone: http://ideone.com/gbklp the problem, others have said, filter creates new collection. alternative withfilter doesn't, doesn't have foldleft . also, using .view , .iterator or .tostream avoid creating new collection in various ways, slower here first...

i'm such amateur @ regex, how allow spaces(doesn't matter how many) in regex? if(preg_match('/[^a-za-z0-9_-]/', $str)) return false; if(preg_match('/[^a-za-z0-9_ -]/', $str)) return false; note put space before hyphen. if space after hyphen, specifying character range underscore space. (issue evadable putting backslash before hyphen escape it.) this assuming mean "allow" is: regex being used validate character string, , if matches , character string disallowed (hence return false ). characters in negated character class ( [^...] ) allowed characters. (this causing general confusion in question.)
