UNIX and Linux System Administration Handbook (5th Edition)

Reddit - 15 min 57 sec ago

I was wondering if anybody knew further information on the 5th edition of the UNIX and Linux System Administration Handbook. The 4th edition is highly recommended in the community as one of the essential books to read.

I'm aware of the sad events of Evi disappearing at Sea, which is a tragedy.

I was browsing through Amazon and I noticed a "UNIX and Linux System Administration Handbook (5th Edition)" available listed for pre-order with a release date of August 11, 2017. I am curious if there is any news if this is a legit release and it's being done by other authors?

Link here: https://www.amazon.com/UNIX-Linux-System-Administration-Handbook/dp/0134277554

I checked Prentice Hall's website but nothing was listed. Anybody have further insight? I was planning on buying the 4th edition, but if the 5th edition is coming out later this year, I may just wait. I'm not sure if they are collaborating with different authors or what.

Superb Way To perform storage migration using lvconvert Without Data-loss and Downtime

LXer - 23 min 47 sec ago
Your Storage system has reached almost to the end of support and you want to migrate to newer technologies. Area of concern here is downtime and data-loss.Of course you can do this using backup and restore methodology or using pvmove. However, smart way for performing storage migration using lvconvert. This method does not involve downtime also it guarantees 100% against data-loss.

The Changes So Far For The Linux 4.11 Kernel

Phoronix - 31 min 38 sec ago
We are now through week one of two for the Linux 4.11 kernel merge window. I've already written a number of news posts this past week covering features I find interesting for Linux 4.11. If you are short on time and behind in your Phoronix reading, here's a quick overview of the material so far for this next major kernel bump...

Using Open Source to Empower Students in Tanzania

Linux.com - 35 min 46 sec ago

Powering Potential Inc. (PPI) aims to enhance education opportunities for students in Tanzania with the help of the Raspberry Pi and open source technology.

“I believe technology is a vital part of the modern human experience. It enlightens. It ties us together. It broadens our horizons and teaches us what we can be. I believe everyone deserves access to these resources,” says Janice Lathen, Founding Director and President of PPI.

The project’s three main technology goals are:

Using Mesos Quotas to Control Resource Allocation

Linux.com - 1 hour 4 min ago

Did you know that Apache Mesos supports quotas? It has since version 0.27. In an ideal world, we could fine-tune quotas to manage resources for maximum efficiency, reining in hogs and making sure that services get what they need without going overboard. In the real world, it's a little more challenging. Should quotas be limits or guarantees? Persistent or dynamic? How granular should quotas be? Why hasn't Quota seen wider adoption?

Good Motherboard for a Linux Home NAS server (ZFS with lots of SATA disks)?

Reddit - 1 hour 5 min ago

Hey,

I'm planning to build a NAS / Combined home media server and backups. I've read up on FreeNAS for ZFS but it seems a bit limited and I'm used to Ubuntu server so I want ZFS on that.

What are some good cheap motherboards that work well on linux server distributions like ubuntu or centos, that also support lots of SATA controllers flawlessly?

I might go for a rack-mounted case but don't need enterprise level / server grade equipment.

Thanks in advance

Containers and OpenStack

  • Stateful containerized applications with Kubernetes

    To date, almost all of the talk about containers and microservices has been about "stateless" applications. This is entirely understandable because stateless applications are simply easier. However, containers and orchestration have matured to the point where we need to take on the interesting workloads: the stateful ones. That's why two of my talks at SCALE 15x are about databases, containers, and Kubernetes, which is an open source system for automating deployment, scaling, and management of containerized applications.

    Stateless services are applications like web servers, proxies, and application code, which may handle data, but they don't store it. These are easy to think about in an orchestration context because they are simple to deploy and simple to scale. If traffic goes up, you just add more of them and load-balance. More importantly, they are "immutable"; there is very little difference between the upstream container "image" and the running containers in your infrastructure. This means you can also replace them at any time, with little "switching cost" between one container instance and another.

  • 13 Companies Leading the Way with Containers

    As DevOps has grown in popularity, an increasing number of organizations are looking to containerization technology as a way to simplify and streamline application deployment and management. In fact, the RightScale 2017 State of the Cloud Report found that Docker, the leading containerization tool, was the most popular DevOps tool among the companies it surveyed. Forty percent of the enterprises surveyed said that they use Docker, and 30 percent more said they planned to do so in the future.

  • AsteroidOS 1.0 Alpha on the Asus Zenwatch 3

    In a previous article, I published a small userspace image and Linux kernel for the Zenwatch 3 that enables root access with SSH over USB on the watch. By now, I reached my initial goal to get AsteroidOS, the alternative Android Wear operating system, running on the Zenwatch 3. Similar to SailfishOS and Ubuntu Touch, AsteroidOS uses the original Android kernel - a patched Linux kernel - with a GNU/Linux userspace that, in turn, also uses some of the original, closed-source Android libraries to access certain hardware like the GPU. As the Android libraries expect a different software ecosystem, e.g., a different C library called bionic, we cannot simply call the Android libraries from within a common GNU/Linux application. Instead, we need an additional software layer that translates between the Android and the common GNU/Linux world. This layer is called libhybris.

    Harman Kardon, the company recently acquired by Samsung, has developed its very own Cortana speaker, which is very similar to the Amazon Echo but featuring Microsoft’s famous digital assistant.

  • 3 cool machine learning projects using TensorFlow and the Raspberry Pi

    In early 2017, the Raspberry Pi Foundation announced a Google developer survey, which requested feedback from the maker community on what tools they wanted on the Raspberry Pi. The blog post says that Google has developed tools for machine learning, IoT, wearables, robotics, and home automation, and that the survey mentions face- and emotion-recognition, speech-to-text translation, natural language processing, and sentiment analysis. "The survey will help them get a feel for the Raspberry Pi community, but it'll also help us get the kinds of services we need," the post explains. Meanwhile, data scientists aren't waiting around to put Google's TensorFlow, an open source software library for machine learning, to work on the Raspberry Pi.

    Let's take a look at a few cool examples of machine learning with TensorFlow on the Raspberry Pi.
