compared subversion can start many workspaces. why can't git repository have more 1 workspace switching branches doesn't necessitate restitution of state before throwing away current branch. if i'm frustrated svn checkout, blow away , start new one. in git, want maintain local repo (and haven't pushed remotely) can't clone new repo. with git, there couple of ways handle this: git stash store working copy temporary area allow switch branches without having committed. git stash apply lay changes down. 2 work in push/pop stack-style mechanism. possible keep multiple stashes , apply arbitrary stash, wouldn't recommend it. throwing out code little easier: git reset --hard head clear working state , revert last head in current branch you're working on. equivalent deleting working copy , checking out again.

here's problem @ hand: need find largest difference between adjacent numbers in list using recursion. take following list example: [1,2,5,6,7,9]. largest difference between 2 adjacent numbers 3 (between 2 , 5). i know recursion may not best solution, i'm trying improve ability use recursion in haskell. here's current code have: largestdiff (x:y:xs) = if (length (y:xs) > 1) max((x-y), largestdiff (y:xs)) else 0 basically - list keep getting shorter until reaches 1 (i.e. no more numbers can compared, returns 0). 0 passes call stack, max function used implement 'king of hill' type algorithm. - @ end of call stack, largest number should returned. trouble is, i'm getting error in code can't work around: occurs check: cannot construct infinite type: t1 = (t0, t1) -> (t0, t1) in return type of call of `largestdiff' probable cause: `largestdiff' applied few arguments in expression: largestdiff (y : xs) in first argument of `max', ...

in javascript , number.max_value represents maximum representable numeric value (which approximately 1.79e+308 , pretty big number) however, if evaluate (number.max_value - 1) < number.max_value in javascript console, returns me false . if use multiplication, works thought : (number.max_value * 0.99999) < number.max_value returns true maybe missing something, possible explanation ? the reason although allowable number range very large, precision of js number (ieee 754 double precision) insufficient represent every possible number in range. doing require 308 digits! hence max_value - 1 indistinguishable max_number .

the task: identifiers must contain @ least 1 non-digit , contain digit, letter, "_", , "-" characters. therefore 'qwerty', 'identifier-45', 'u_-_-', '-42-' valid identifiers. and '123456', 'w&1234', 'identifier 42' invalid. can achieve regular expression. id.match(/\w\d/) or more 1 match id.match(/\w/) && id.match(/\d/) or may make array of permitted characters , filter original string removing them (if rest more [], there forbidden ones)? id.to_a.select{|character| !((0..9) + (a..z) + ['-','_']).include?(character)}.count == 0 i.e. permitted characters excluded string, , if length more 1, there forbidden characters (like & ) using positive lookahead: pattern = /^(?=.*\d)[-\w]+$/ pattern =~ 'qwerty' # => 0 pattern =~ 'identifier-45' # => 0 pattern =~ 'u_-_-' # => 0 pattern =~ '-42-' # => 0 pattern =~ ...
