kandi X-RAY | eventTimer Summary
A drop-in replacement for setTimeout and setInterval that makes use of requestAnimationFrame. The eventTimer, when called, creates a single timer that you can use to queue additional events if needed. When all events in the queue are expired, the timer stops. The goal was to try to create a timer that calls the function as close to the requested time interval as possible. This code is an almalgamation of various timers I've seen used. Once called, the timer loops using requestAnimationFrame. Within each loop it calculates the time between requestAnimationFrame calls and subtracts each interval from the requested wait time to count down to the callback. When it gets within one frame, it determines whether the function should be called now or wait until the next frame to minimize error (based on the average framerate).

QUESTION
When I try to autowire MicrometerRegistry to a class containing KafkaListener, I get the following error -
...ANSWER
Answered 2020-Oct-22 at 16:40at io.micrometer.core.instrument.ImmutableTag.(ImmutableTag.java:35)
.tag("topic", topic)
The topic variable is null.
If it has a @Value annotation, you can't use it in the constructor; create the meter in an @PostConstruct method instead.

I'm trying to implement timer that counts the next event from the JSON API. Unfortunately the API does not support filter so I have to process it on the component
here's the code:

QUESTION
I have a timer of X seconds, and I want Y to count down to zero in even spaces of time, reaching 0 at the same time the timer finishes.
For example, If I had a timer of 10 seconds, and a value of 20, I would want the value to go down by 2 every second.
The timer would preferably update quickly as it will be displayed as a bar.
Thank you for your help!
For context, here is the timer I am using:
...ANSWER
Answered 2020-Apr-01 at 12:01The fraction of Y when T time is left is Y*T/X. Here's a simple TimerTask that ticks X times, going from Y (exclusive) down to 0.0 (inclusive).
If you want to show this in a GUI you'll have to figure out how to publish the current value to your UI framework. Remember that run() runs in the timer thread, not in the GUI framework thread, so you can't directly modify the UI from TimerTask.
QUESTION
This code should render the image sing.jpg in the /www directory after the countdown finishes. This works rendering normal text but with an image - as I have implemented it - I receive the following error:
argument 1 (type 'closure') cannot be handled by 'cat'
Why is this?
...ANSWER
Answered 2020-Mar-06 at 19:02I would create a separate output in ui such as imageOutput to show your image. In addition, I would make timeLeft a separate reactive expression that could be referenced by both eventTimeRemaining to show the countdown, as well as msg (a separate output created).
I was not sure how you wanted to handle the initial condition - I set the default EventTime to Sys.time() but if you use NULL or don't initialize then would need to check for NULL in output and timeLeft calculation.
QUESTION
I use the following code to do a 3-second countdown after a button is clicked. I would like the output to change to something else e.g "Countdown finished" once the countdown hits 0.
How do I listen to the countdown output (which is not an input) in real-time to see when the countdown hits 0 and trigger something else?
...ANSWER
Answered 2020-Mar-06 at 15:48TLDR: Make the EventTime reactive
One thing to note, the way you have it set up now, the output is getting recreated every time the observeEvent is triggered. What you really want is it to just get updated based on some trigger. Here's the code for the server function:
QUESTION
I've been looking through the docs for the better part of the day now and have been unable to figure out how exactly this should be done.
I'm looking to run an event every week, every saturday at 00:00 until monday 00:00 (48h).

Answered 2018-Aug-14 at 13:01Here is a snippet to get a "next Saturday, midnight" LocalDateTime instance, then the hours and minutes until then.
QUESTION
I try to aggregate two streams like that
...ANSWER
Answered 2018-Mar-05 at 18:05I see that you are using System.currentTimeMillis which might be different from the TimeCharacteristic (event time, processing time, ingestion time) that your Flink job uses.
Try getting the timestamp of the event ctx.timestamp() then add the 5000ms on top of it.
