i'm starting web developer , following question sake of connecting several new things in brain: ror 'routes' file alternative apache 'mod_rewrite' module? thanks in advance participating. it's similar in list of url patterns, each pattern having rules associated it. the main difference routes internal rails: mod_rewrite come decision route, , serve file, or pass request on proxy handle, can thought of standalone process in request pipeline. routes.rb on other hand can thought of runs inside rails , decides object (where objects controllers) should have method called on it, passing through request object. maybe isn't happens it's this. rails black box request comes in , response comes out, , routes inside box. so, guess it's alternative mod_rewrite, because instead of using mod_rewrite apache pass requests rails , let rails (using routes.rb code) figure out. it's kind of different thing. edit: re-read , realised it...

i can following in bash : declare -a data data[a]="aaa" data[c]="ccc" data[b]="bbb" in "${!data[@]}" ; printf "%-20s ---> %s\n" "$i" "${data[$i]}" done which outputs: a ---> aaa b ---> bbb c ---> ccc that is, associative array reordered (i assume using lexicographic ordering on keys, not sure), , loses original order in created data. wanted instead: a ---> aaa c ---> ccc b ---> bbb in python use ordereddict instead of plain dict that. there similar concept in bash? as answered, associative arrays not ordered. if want ordering in array, use below work-around. declare -a data data_indices=() data[a]="aaa"; data_indices+=(a) data[c]="ccc"; data_indices+=(c) data[b]="bbb"; data_indices+=(b) in "${data_indices[@]}"...
