How to create startProcess with a specific priority - nim-lang

I am using startProcess from osproc to create a process but it seems that the priority is hardcoded in the source code to normal. How to start a process with a lower priority?
I've tried to copy paste startProcess with a specific priority in my source code but have errors I do not know how to deal with. I also tried to call winlean.createProcessA(...) but get undeclared identifier.
Any idea?

Tracing a value over its lifetime in a Nodejs program

I have a NodeJS program that's erroring out in an unexpected place. I've isolated the value producing the error, but the stack trace is too deep for me to know where the value is being created. Ideally, I'd like to follow the value from its creation all the way to the error to get a better sense of what's going on.
As the program is fully deterministic based on its initial input, the same code path used to produce the value will run every time I reproduce this bug. Is there a Node debugger, then, that will identify a value on one run of a program and then look for it & trace it on subsequent runs of the program? Thanks!

Link the different sources with delay time specifically for each source

I have a system that starts with 3 sources which are small, medium, and large. I want to do it for 3 different types of sources, combining and passing through a delay block. The delay block will be linked with a database reference which is a table consists of 2 columns (source, delay time). Thus, when the source passes through the delay block, it will automatically read the table and set the delay time for different types of sources.
I had seen the description in the AnyLogic Help and follow the instructions. The error is from the delay block which is the choice condition. I put source equals to agent.name but it keeps giving me an error which is name cannot be resolved or is not a field.
The source which produced an agent doesn't automatically get stored into the agent name. Plus, I think there isn't such as thing as name field in an agent. You can check out API here. What I think you could do:
In your agent create a property, let's call it sourceName
In Source on at exit action set the source name into the agent.sourceName property
Check the value of that property in your Delay block by checking value of agent.sourceName

Managing different Python scripts with different priority to each

I need to run different Python processes, in a certain order of priority.
Specifically, I have 3 processes, and I need them to work this way:
An object detection script, used to locate a person and their position. I need this one to run continuously at a high FPS;
another process that, once some conditions are met (when the person is present in the picture in the required position) starts taking screenshots of the image for a certain amount of time;
another script that analyzes the screenshots taken by the second one.
I wrote the 3 scripts already and they work fine, but the problem is that process 3 is particularly computationally demanding, and I don't want it to prevent processes 1 and 2 from running smoothly.
My idea is that I could give highest priority to process 1, and send screenshots taken by process 2...to a queue, or something like this.
When the person is not detected in the picture, I could run process 3, and empty the queue as the screenshots are analyzed. However, script 3 should still run with limited resources, so that FPS of script 1 isn't affected too much, and it can still detect if the person enters the picture again.
I'm afraid this might all be a little vague, but could you please suggest me a way or tool I could use to manage the processes this way?
So far, I tried simply saving the screenshots to a folder, but I don't know how to limit the resources usage by process 3.
I'm familiar with the basic usage of Docker, so I was thinking that maybe I could:
run the processes in different containers, limiting resources allocated to the 3rd one (?);
use a message broker (Kafka, RabbitMQ?) to store screenshots;
but again, I'm a newbie when it comes to this stuff (speaking of which, I hope I tagged this question correctly), so I don't know if it's an efficient way to to do this (or if it can be done this way, for that matter).

How to find the time when a Puppet manifest is executed

I'm wondering if anyone knows a good way to get the date and time when a portion of code in a Puppet manifest is actually executed. Sometimes my manifests take a long time to run, and I need to schedule a task to occur soon after the end of the run, no matter when that occurs.
I have tried the time() function, setting a variable using generate() (using the date function on the Puppet master), and even creating a custom fact, but everything I've tried gets evaluated when the manifests are parsed on the server, rather than when they actually execute on the client.
Any ideas? The clients are all Windows, FWIW.
Thanks in advance!
I am not sure I understand what you mean, but you can't get this information during catalog compilation (obviously), so you can't use it to change the way the catalog will be applied.
If you need to trigger another process on the same host, then you should use any IPC mechanism you have available. You can exec anything, and have it happen just after any other resources is applied, so it is just a matter of finding the proper command.

meaning of enqueue_head macro linux

I am not sure what is the meaning of the macro ENQUEUE_HEAD in linux mean. I have an intuition that it means to enqueue a task after it has woke up but still want to be sure.
Note: For reference purposes in v3.5.4 it is defined in /include/linux/sched.h and referenced at many place but one such place I am having problem is function enqueue_task_rt in file ./kernel/sched/rt.c
sched: Add enqueue/dequeue flags
ENQUEUE_HEAD - the waking task should be placed on the head
of the priority queue (where appropriate).
