if statement - Rock paper scissors in Ruby -


i have implement small part of rock, paper, scissors game assignment. here code:

class rockpaperscissors    # exceptions class can raise:   class nosuchstrategyerror < standarderror ; end    def self.winner(player1, player2)     # code here      puts "player1 = " + player1[1]     if (player1[1] || player2[1] != 'r') || (player1[1] || player[2] != 'p') || (player1[1] || player2[1] != 's')       raise nosuchstrategyerror.new("strategy must 1 of 'r','s','p'")     else       if player1[1] == player2[1]         return player1       elsif (player1[1] == 'r' && player2[1] == 'p') || (player1[1] == 'p' && player2[1] == 's') || (player1[1] == 's' && player2[1] == 'r')         return player2       else          return player1       end     end   end    def self.tournament_winner(tournament)     # code here   end  end

i using rspec test out code , breaks in both of below cases. assuming has check make sure input valid, , though input valid, whatever reason, way doing line if (player1[1] || player2[1] != 'r') || (player1[1] || player[2] != 'p') || (player1[1] || player2[1] != 's') making input fail on every case. how can fix line if input valid, doesn't raise error?

failures:    1) rockpaperscissors game rock breaks scissors [10 points]      failure/error: raise nosuchstrategyerror.new("strategy must 1 of 'r','s','p'")       rockpaperscissors::nosuchstrategyerror:        strategy must 1 of 'r','s','p'      # ./lib/rock_paper_scissors.rb:11:in `winner'      # ./spec/rock_paper_scissors_spec.rb:10:in `block (3 levels) in <top (required)>'

edit: player1 , player2 arrays format ["playername", "move"] move being either r,s or p rock, scissors or paper

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
