node.js - Using Underscore or lodash in Nodejs for realtime computations ? Performance? -

-

i'd use lodash in nodejs project pluck,intersection,zip etc.. have mongodb collection 'onlineusers' , has 'params' array in every user(doc) .the redundant job app find intersection on params array of 1 user rest of users , find user2 user1 has interesected params .

there might around 500-600 onlineusers want scale upto thousands. dont know if aggregation framework helps making array intersections

using underscore or lodash in realtime finding intersections of 100 or 1000s arrays normal ? need response less 2s atleast .

anyone benchmarks(pluck , intersection) great

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
