memory management - Java Hashmap. How many maximum records should it be used for? -

-

i have 10,000 mappings. idea put them in java hashmap , access ? save database transactions 10,000 records present in memory itself. every mapping have around 100 characters including key , value , mappings quite distinct. asking question since don't have great experience in java or on similar situation.

10k objects drop in bucket (pardon pun) far memory goes.

try , see, think you'll find modest memory capacity these days handle it. make sure have reasonable heap size: -xmx512m or whatever

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.
