kandi X-RAY | tock Summary

tock is a JavaScript library typically used in Server, Runtime Evironment, Nodejs, MongoDB applications. tock has no bugs and it has low support. However tock has 1 vulnerabilities and it has a Non-SPDX License. You can install using 'npm i tock' or download it from GitHub, npm.

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.

            Sending a message from background thread to UI Thread in real time
            Asked 2020-Dec-14 at 15:43

            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?

            clock_gettime takes longer to execute when program run from terminal
            Asked 2020-Aug-03 at 20:07

            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.

            ANSWER

            Answered 2020-Aug-03 at 20:06

            Just 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.

            The 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.

            There 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 use ref (const timeInterval = React.useRef(null); ... timeInterval.current = ... ; clearInterval(timeInterval.current);
            • Also you need to remove counter = 1; from your pressingDowm function, because before each setMs you are incrementing it by one

            How to pause an asyncio created task using a lock or some other method?
            Asked 2020-Apr-10 at 22:07

            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".

            Answered 2020-Apr-10 at 22:07

            You 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:
