i trying discard local changes , seems after type $ git checkout -- . .. changes seem still there... if try: $ git checkout head . .. works, changes discarded! why happening? ideas? hint: changes seem relevant line endings, no real content edited (that why needed discard after all) update : use git 1.9.5 windows. local changes unstaged, uncommited, under workingtree after upgraded git version 2.11.1.windows.1 this stopped happening (maybe earlier version - bettween 1.9.5 , 2.11.1 - had solved issue)

gnupg - How is the process of signing and verifying a release and why apache says that the signature file signed by a public key? -

i have started learning gpg , bit confused infos have found. gnupg documentation says that a signature created using private key of signer but @ apache's site , say: the signature file digest of original file signed public key ... and on same site, in section , following: a digital signature created original document using private key . now suppose process of signing involves signing hash of release using private key of holder , not public 1 apache says in second link have posted, or wrong? otherwise, how ever able decrypt hash of release signed public key if he/she doesn't have private key of holder? then, explain in processes of signing , verifying signature consist , passages, e.g. software release apache maven ? tl;dr : there mistake in documentation, understanding of signatures right. the signature file digest of original file signed public [sic, should private] key... signing document performed calculating hash sum of docum

haskell - Finding a single element in a list using list comprehension -

-
the function valueof gets int value of corresponding string out of tuple list. can explain how third line works? type state = [(string,int)] valueof :: state -> string -> int valueof xs var = head [b | (a,b) <- xs , ==var ] i've never seen haskell expression that, i'm more used expression this: (\xs -> length xs > 15) there no lambda expression. seeing list comprehension, way of creating list of values satisfying condition. in case comprehension [b | (a,b) <- xs , ==var ] means like: create list of b s such (a, b) element of list xs , a equal var . in imperative pseudo-code write as result = empty_list (a,b) in xs: if == var: result.add(b) return result so, whole valueof function works generating list of values have right string key, , uses head function first one. note if there no match, whole computation crash.

javascript - Safe way to store data for button clicks -

-
i trying find out safest way store data use when user clicks on button. i know can store data in attributes(either value attribute or data- attribute) of button tag so: <button type="button" value="1" data-value="1">click me!</button> but problem user(probably advanced users) can manipulate value firebug or other app , click button , send on different data. understand need check input before try sent data. i found out use jquery's .data() attach data dom elements, seems bit more useful. i'm not sure how data stored, assume harder manipulate. what got me interested in question when looking through soundcloud's code in firebug, saw none of "like" buttons had data attached buttons. tried deleting/manipulating elements/data , buttons still worked. got me thinking using similar process jquerys data() doing. i want know if there safer way store data or way user can't manipulate data before clicking button.

lua - 3 point object moving is happening all at once -

-
i making jumping game there object @ left side of screen, on platform. once object jumps , lands on platform on right, following: 1) platform on right moves left 2) platform on left (that jumped off from) moves off-screen. 3) new platform supposed appear @ right side of screen, continuing loop. i have made functions allows object jump , show if collision successful or not. problem is, 3 things have mentioned above happens, keeps on going , not stop object make next jump. makes object go off screen well, since platforms keep moving towards left. after debugging, feel problem lies collision happens. because, once touches platform, collision keeps on happening until object off of platform. wondering if guys can me this! here part of code relevant: local onplatform = false local gamestarted = false function playercollision( self, event ) if ( event.phase == "began" ) --if hit bottom column, u points if event.target.type == "player"
