kandi X-RAY | tock Summary
Tock is a feature-rich distributed cron/job queue. It has the ability to spawn jobs on remote servers using axon as a transport layer, including a basic form of load balancing. The remote server will spawn the job, and stream the output back to the tock master process. Included in the tock package is an admin UI and API for creating scheduled jobs, one-off jobs, a dashboard for watching jobs in progress, and statistics about jobs. Tock uses MongoDB as the internal storage mechanism for schedules, and job results. The standard out and standard error outputs are stored as files in gridFS. Mongoose.js is used as the API into MongoDB.

QUESTION
I am building a metronome in android with sound and a visual blink and of course both things need to be in sync. The problem is that the audio processing happens inside a background thread and as we all very well know "only the thread that created the thread hierarchy can change it's views" therefore I needed a way to get the UI thread to change the veiew. So how can I update the ui thread in sync with the beat I am producing? Both things don't seem synchronized. Is there a better way to achieve this than the method I depict below?
This is the current code I have:

In your service create the LocalBradcastManager

I have raised the SO Question here and blessed to have an answer from @Scott Boston.
However i am raising another question about an error ValueError: Columns must be same length as key
as i am reading a text file and all the rows/columns are not of same length, i tried googling but did not get an answer as i don't want them to be skipped.

QUESTION
I was trying to measure the time for a snippet of code and noticed that the timings were about 50ns faster when I ran the program from inside my editor, QtCreator, compared to when I ran it from a bash shell started in a gnome-terminal. I'm using Ubuntu 20.04 as OS.
A small program to reproduce my problem:
...ANSWER
Answered 2020-Aug-03 at 20:06Just add more iterations to give the CPU time to ramp up to max clock speed. Your "slow" times are with the CPU at low-power idle clockspeed.
QtCreator apparently uses enough CPU time to make this happen before your program runs, or else you're compiling + running and the compilation process serves as a warm-up. (vs. bash
's fork/execve being lighter weight.)
See Idiomatic way of performance evaluation? for more about doing warm-up runs when benchmarking, and also Why does this delay-loop start to run faster after several iterations with no sleep?
On my i7-6700k (Skylake) running Linux, increasing the loop iteration count to 1000 is sufficient to get the final iterations running at full clock speed, even after the first couple iterations handling page faults, warming up the iTLB, uop cache, data caches, and so on.
QUESTION
Trying to automate the clock for Delay Flip Flop in the testbench, because I don't want always do it manually like this:
...ANSWER
Answered 2020-Jul-03 at 15:15The main problem is that the forever
loop prevents the $display
and $monitor
code from executing. You should separate the clock out into its own initial
block. I also added a $finish
statement to cleanly terminate the simulation.
I had to move your parameter
declarations above their usage because I got compile errors with your code on different simulators.
QUESTION
I'm trying to return the number of seconds whilst holding in a button.
eg: "click+ hold, inits -> counts & displays 1, 2, 3, 4, 5 -> leaves button -> resets back to 0"
I've gotten close. It works fine, in my console, but whenever I try to update the state it ends up in an infinite loop.
...ANSWER
Answered 2020-Jun-29 at 11:24There are two problems with your code:
- You are not clearing interval.
timeInterval
is a new variable whenever your component is re-rendered. You need to useref
(const timeInterval = React.useRef(null); ... timeInterval.current = ... ; clearInterval(timeInterval.current);
- Also you need to remove
counter = 1;
from yourpressingDowm
function, because before eachsetMs
you are incrementing it by one
QUESTION
This is a sample program of something I'm trying to do in a main project, but the main idea is that I created a task using a asyncio.create_task. I want to then pause that task later on in the code when some event happens. In this sample code, asyncio.create_task starts task_tic_tock and prints "tic-tock". Later in the code, when other_task has a count that is divisible by 3, it takes a lock and starts task_tic_tock with the parameter being False. I'm not sure a lock is the best thing to use, but the behavior I am hoping for is for it to print "In new count" and "print val is now false", but not "tic-"tock". Once the lock ends I want it to resume printing "tic_tock".
...ANSWER
Answered 2020-Apr-10 at 22:07You can achieve what you want with a lock. The issue with your code is that you never acquire the lock in start_tic_tock
, so you have no way to 'pause' that coroutine based on the lock you acquire in other_task
.
You can fix this by making your start_tic_tock
method acquire the lock as follows:
