As far as I read in a OS text book (Operating Systems by Silberschatz) Kernel mode is for privileged task, so it it true to claim that "User Level Thread can read/write Kernel threads" ?

Generally speaking, Is there any kind of protection between user and kernel level threads?

## How to fix the error and do thread to those equation

## Does every thread have its main function?

Does every thread have its own main function?

I know that its have its own stack, but what about main function (not necessarily a function which called main).

For example, when creating a thread, we pass a function as an argument for the new thread to run it.

## Why does Fully Utilized Thread Change over time?

While I was running a simple program which needed to run for a couple minutes, I made an observation I can’t find an answer for on google.

Here is a snip of my system monitor which demonstrates my computer switching which processor is at full capacity while running my program.

This isn’t causing me any trouble, but I find it interesting, because I would assume that switching between units would take more time than just running at 100% capacity the whole time on one unit. Is there any simple explanation for this behavior?

Thanks!

## When is a set of emails an email thread?

How do you know when a set of emails is an email thread? Like, what parameter do you evaluate whether you have an email thread or not?

Do you use the `Reference` and `Message-ID` fields to check if you have a thread or not? Or what do you do?

## Thread – contention vs race

The terms `contention` and “`race$$“$$ are used interchangeably when it comes to thread’s state(at critical section). Are they same?

## What is gmain and Input thread?

So i was running this command: sysdig evt.dir=\< and not ( ) , and there were a few results that seemed kind of strange. There are two processes, one named gmain and the other InputThread. They’re threads, so they don’t show up on top. In htop, when enabling show user threads and kernel threads, I have to take the thread ids from sysdig and correlate them to the htop output. Some of the comm names there are Xorg, libwhisker.so.

In /proc, the ids there are non existent, and ps does not show them as well. Because they’re threads, they’re supposed to be in /proc/pid/task/tid. If i were to ls /proc, the directories are non existent, but i’m able to cd into /proc/ even though they’re not there. And also the one that leaves me puzzled is, if i were to run sysdig and start running firefox, the entire machine hangs.

And so the question is, is this supposed to happen? Is the use of sysdig kernel probes and a running firefox a bad thing? Why do these process ids that i got from sysdig not appear when i do an ls, but a cd into them works? What is gmain, which according to only 2 relevant entries in a google search, is a gnome associated process, but i’m running xfce?

## royserpa how can you take peoples money and close the thread?

I posted that i wont use the hacking bullshit mentioned in your pdf and that the 1st method will not rank without the things you say you do not need.

Ive been doing youtube for years and i know better
If you can get a hangout to rank without any of the things you say you dont need prove it and ill go away
Far as the other two methods i am not interested and wont a refund
Your post for that sale was a outright lie
