NFSv4: A Unix Mainstay Learns New Tricks

NFS has traditionally been a semi-robust method of sharing files between Unix-based computers. The IETF has been working on NFSv4 since early 2000, and implementations have finally started springing up everywhere. The Linux kernel team has focused its efforts in NFSv4, providing its least buggy NFS implementation yet. If that alone isn't reason enough to start using v4, read on.

Some key features are:

* POSIX ACL support, including Windows ACL interoperability.
* Locking enhancements, including advisory and mandatory locks.
* Data replication or migration is made easier with NFS's help.
* TCP-only, with tons of improvements, making NFS over WAN links viable.
* No more portmap, lock manager, mount and RPC hell; NFSv4 uses RPC, but all over port 2049.
* Security, for the first time: authentication, cryptographic integrity and encryption are all possible.

In short, NFSv4 has addressed every major complaint ever registered about NFS.

What happens when a non-coder tries to learn Linux

The Linux Foundation has created all of the content for the course, including the videos, written text, activities, and labs. It's clear to me that their content team has made an effort to space out the videos between the written material in a way that gives you a break from endless reading. Also, each video is only approximately 30 seconds to 2 minutes long. They avoid getting into the weeds too much at once, giving you chunks of knowledge, letting you test it out, then moving on to another topic. Each chapter points out that as the course progresses, you will go into further depth with each topic. Read more

Jailhouse 0.1 released

This release particularly means full exploitation of VT-d DMA and interrupt remapping to isolate assigned PCI devices from the hypervisor and foreign cells. Moreover, the usability of Jailhouse was greatly improved by the introduction and continuous extension of a generator for system configuration files. Finally, a framework for writing basic cell applications is available now. With a few lines of C code you can set up timer interrupts, read clocks or configure PCI devices for the use in simple bare-metal real-time applications. Read more
