sched | Supports | Cron Utils library

I dived deep and found out that

managedStream->getXRunCount();

Returns the number of XRuns for the streams whole lifetime. I thought it would return the value relative to previous call. So apparently I was getting 12 but there were no underrun because this was from the session which had previous underrun.

time.sleep() is not async so it will freeze your program. Use await asyncio.sleep(). This is because it is pausing the whole program, not just that function.

The reason you’d want to use wait() here is because wait() is non-blocking, whereas time.sleep() is blocking. What this means is that when you use time.sleep(), you’ll block the main thread from continuing to run while it waits for the sleep() call to end. wait() solves this problem.

Use crontab or if you want to do within python and not interfere with linux use of schedule library.

Evaluating the model works, but I can't seem to find how to make a prediction with a single image. How can I do that?

Simply, if you have a single image make sure to:

• use additional 1 dimension at the beginning
• make sure to use CHW format instead of HWC (or specify that within pytorch, check out how to do that here)

For example:

Everything in your code seems right. But a few things which I think is making error in your application.

IN MainActivity.class :

Try removing tabLayout.setupWithViewPager(viewPager);

And edit by replacing mainActivityFragmentsAdapter = new MainActivityFragmentsAdapter(getSupportFragmentManager());

to

mainActivityFragmentsAdapter = new MainActivityFragmentsAdapter(this, getSupportFragmentManager(), tabLayout.getTabCount());

IN MainActivityFragmentsAdapter.class :

Replace

I found a reason. When invalidate two SKGLView simultaneously, I face JNI ERROR (app bug): accessed deleted Global 0x606a.

So, I change from SKGLView to SKCanvasView. After that, issue never showed up.

While you can technically open and read files from kernel space, it's usually a bad idea for multiple reasons. Whatever information is provided under /proc is already available to the kernel, you just need to figure out where it is and how to obtain it, and you will be able to do everything in your module without reading any file.

You are interested in knowing how much RAM is a particular process using given its PID, and you are correct that this statistic is available in /proc//status: in fact, it is labeled as "VmRSS" which means "virtual memory resident set size". If we take a look at the kernel source code, we can see exactly how that number is calculated:

The kernel function called when reading /proc//status is proc_pid_status() in fs/proc/array.c, which then calls (among the other things) task_mem().

I did more digging and found some functions that are helpful.

Include these:

Whether pthread_yield can/will do what you expect (i.e. make the HELPER run first) depends on the system scheduler being used and how it's configured.

In general you can only expect (or rather hope for) such behavior on systems with very simple schedulers. A modern (Linux) system will - per default - use a more complex scheduling so you can't rely on pthread_yield to synchronize the order of execution.

And even if MAIN was stopped and the HELPER was started, the HELPER could be preempted before doing the printing. Or how about multi-core CPUs? What if both threads ran in parallel? Which would do the print first?

So - No, pthread_yield is not the tool for syncronizing threads.

For more on scheduling read:

https://man7.org/linux/man-pages/man7/sched.7.html

Here you can read about a number of system calls that you can use for getting information about the scheduler and configure the scheduler.

But in order to control the thread execution order, you shouldn't rely on controlling the scheduler. Implement your own control, e.g. by using a mutex
