i have observable emits stream of values user input (offset values of slider). i want debounce stream, while user busy sliding, emit value if nothing has come through for, 100ms, avoid being flooded values. want emit value every 1 second if endlessly debouncing (user sliding , forth continuously). once user stops sliding though, want final value debounced stream. so want combine debounce regular "sampling" of stream. right setup this: const debounce$ = slider$.debouncetime(100), sampler$ = slider$.audittime(1000); debounce$ .merge(sampler$) .subscribe((value) => console.log(value)); assuming user moves slider 2.4 seconds, emits values follows: start end (x)---------|---------|---(x)|----| | | | | 1.0 2.0 2.5 3.0 <-- unwanted value @ end ^ ^ ^ sample sample debounce <-- these i don't want value emitted @ 3 secon...

(if familier docker, docker waits 10 seconds, , kill container, because didn't respond sigterm , again if not familier docker, ignore info). #!/bin/bash export path=/usr/local/samba/bin/:/usr/local/samba/sbin/:$path if [ -f /usr/local/samba/etc/smb.conf ]; exec /usr/local/sam...

i need write sort_contacts function takes dictionary of contacts parameter , returns sorted list of contacts, each contact tuple. the contacts dictionary passed function has contact name key, , value tuple containing phone number , email contact. contacts = {name: (phone, email), name: (phone, email), etc.} the sort_contacts function should create new, sorted (by last name) list of tuples representing of contact info (one tuple each contact) in dictionary. should return list calling function. for example, given dictionary argument of: {("horney, karen": ("1-541-656-3010", "karen@psychoanalysis.com"), "welles, orson": ("1-312-720-8888", "orson@notlive.com"), "freud, anna": ("1-541-754-3010", "anna@psychoanalysis.com")} sort_contacts should return this: [('freud, anna', '1-541-754-3010', 'anna@psychoanalysis.com'), ('horney, karen...

i implementing java/swing application macos, common mouse button related behavior disabled until window activated. in other words, when mouse button pressed on inactive window, window activated nothing else happens. (there exceptions. buttons when clicked activate window , run normal action.) there way this? basic problem time application gets mouse pressed event, window active. thought far correlate window activated event , mouse pressed event time, might not reliable. you can make button's contains() depends on frame's active or not: final jframe frame = new jframe(); jbutton button = new jbutton() { @override public boolean contains(int x, int y) { return super.contains(x, y) && frame.isactive(); } }; when frame deactive , region of button clicked, button won't accept mouse event since contains() returns false, button's parent tested contains() instead (and parent's parent until returns tru...
