Interesting patches

I always had to adjust the text size and the line pitch to make the slides pleasant i.

Course Overview

While creating the slides I wanted to have my usual working environment an old version version 1. Very time consuming and peeving.

In fact the disadvantages caused my work on Acclaim as I wanted a presentation program whose slides where easy to create at least for myself. First version on June, 12th Download Apart from the original Keynote version I did exports to some other file formats as Keynote is not really available for many platforms i.

Daniel O. The approach that the patches so far have taken is to just add scheduling points all over the map. It's wrong.

It's distasteful. And it leads to more and more crap over time.

The support for namespaces initially appeared in 2. For instance, a containerized nginx web server exposes external PIDs for its master and worker processes:.

We can provide another option to the ps command so it also shows the cgroup to which the process is bound. The output is much more verbose now, but we can see processes are attached to the cgroups of the docker hierarchy, and so assume those are running inside container. Surprisingly, the life of a container starts by issuing a clone system call which creates a new process descriptor.

The newborn process can share a number of resources with its parent process depending on the value of the flags argument. Typically, both child and parent share the same memory address space until one of them decides to write a new memory page, when a copy of that page is moved to the address space of the process which requested the write operation this optimization technique is commonly known as CoW.

Besides sharing the memory address space, they often share file descriptor table and file system information.

Course description

For each of them a new namespace is created and the child process becomes the member of that namespace. The process can call unshare system call as an alternative mechanism to namespace creation, as well as it can join an existing namespace via setns syscall. Mount namespace isolates the set of mount tables.
