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?
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.submitted by /u/zirge
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:
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?
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.

While the project is dying, the team has offered help to anyone who is willing to continue this project. The team will guide through all the process and even teach if needed. If anyone is interested in continuing this project, now is the time. Otherwise we all have to say goodbye to Manjaro-ARM.
This is the second edition of TWTWTW, a weekly blog proclaiming noteworthy news in the open source world. It provides a concise distilled commentary of notable open source related news from a different perspective. For the second edition, we present a succinct catchup covering software, hardware, book releases, ending with a real Barry Bargain!
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.
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.
The OpenStack Foundation has released Ocata, the 15th iteration of the popular open source cloud platform. The latest release has focused on enhancing core compute and networking services and expanding support for application container technologies.
The RDO community is pleased to announce the general availability of the RDO build for OpenStack Ocata for RPM-based distributions, CentOS Linux 7 and Red Hat Enterprise Linux. RDO is suitable for building private, public, and hybrid clouds. Ocata is the 15th release from the OpenStack project, which is the work of more than 2500 contributors from around the world (source).
Two Walmart associates who spoke recently at the Linux Foundation’s Leadership Summit provided some updates on the retailer’s efforts to automate its business.
According to Andrew Mitry, a distinguished engineer, Cloud, and Megan Rossetti, a senior engineer, Cloud, the company is expanding its cloud services to encompass more than its e-commerce business. And it’s streamlined its cloud services and DevOps teams into one group for the whole company.

Thomas Rini of the Konsulko Group presented at this week's Linux Foundation Embedded Linux Conference (ELC2017) about the state of U-Boot.
Rini has served as the "head custodian" of U-Boot for the past number of years and presented on the overall state and accomplishments for this Universal Boot Loader most commonly associated with ARM and other architectures.
Nuclear is a beautifully designed Open Source multiplatform music streaming app that fetches media content from multiple online sources including YouTube and last.fm. The app has a simple yet glossy UI and does an excellent job at playing audio files. It was developed using Electron and can be thought of as the GUI version of mps-youtube with just a few customization features under its belt.
There are various comic book reader apps for Linux out there but today we bring you Peruse – an Open Source comic book reader developed by the KDE team to simplify reading comic books on your KDE desktop environment and to make it more pleasurable.
Peruse has a simple and intuitive UI but I must admit that it is a just a couple of paces away from boring – the app needs a better-polished look to be able to compete with already famous comic book readers in the market.
Calibre developer Kovid Goyal is pleased to announce the availability of version 2.80 of his hugely popular, open-source and multi-platform ebook library management software.
Calibre 2.80 comes two weeks after Calibre 2.79 and appears to be a major release that introduces quite a bunch of new features and new news source, besides the usual bug fixes. The most significant addition being the ability to sideload KFX files that have been created using the third-party KFX plugin for Calibre.
Undergoing rapid expansion, MyRepublic found it was increasingly challenging to innovate and grow via its existing infrastructure. Scaling out services, handling spikes in user demand, and resolving outages by simply re-using spare capacity from other services were also difficult to address with the ISP’s legacy infrastructure. Faced with the costly renewal of its proprietary software and aging hardware, MyRepublic chose to modernize its IT platform with a more scalable and flexible platform that could better meet its needs.
The official Ubuntu 17.04 flavors are available for download. Here's a quick look at what's new in the latest 17.04 beta release of Ubuntu Budgie, Xubuntu, Ubuntu GNOME, and Kubuntu.
This article doesn't cover Lubuntu, Ubuntu Kylin and Ubuntu Studio, flavors that also had a 17.04 beta 1 release, but which don't seem to have any interesting changes, at least according to their release notes. Other flavors, such as Ubuntu MATE, as well as Ubuntu (with Unity) did not take part in the 17.04 beta 1 release.
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.
And since Cortana is the key feature of this little device, it only makes sense for Harman Kardon to turn to Windows 10 to power the device. And yet, it looks like the so-called Harman Kardon is actually running Linux.
Mobile is the hottest industry. Banking and payments are rushing to mobile. Governments doing healthcare and education with mobile. Travel from airlines to taxis to trains and busses to hotel bookings is going mobile. Your driver's licence is migrating to the mobile phone as are your keys to your home. And all the other big tech stories from Internet of Things (IoT) to 'Big Data' analytics to Cloud computing - are all dependent on mobile. And next week we have the massive industry event in Barcelona, Mobile World Congress. My brand new TomiAhonen Almanac 2017 is now finished and is released today. So this is the perfect time to do my annual 'State of Mobile' blog of the major statistics. What are the big numbers. Lets start with reach. Yes, mobile is by far the most widely-spread communication technology humankind has ever witnessed.
The Tizen Store, as the name suggests, is the Tizen Application Store for developers to publish their free and paid for Tizen apps. In April 2015, we saw the store expand it’s coverage to include 182 countries, which was mainly for FREE apps, but we saw this as setting the foundation for providing paid for apps further down the road.
All three smartphones are running Android 6.0 Marshmallow, which is disappointing to see regardless of how affordable a device may be. The A3 and the U5 also come with special capabilities when it comes to your selfie taking needs, with features like Face Mask, Face Show, Selfie Album, Face Beauty, and more available.
Nearly two months after ZTE announced that the Blade V8 Pro would be coming to the US, the company is adding two new devices to the line: the Blade V8 Lite and Blade V8 Mini. Both phones will only be initially available in the Asia Pacific and Europe, including Russia, Japan, and Germany. Let’s check out the specs:
If it wasn't already clear that Lenovo is trying to cover every conceivable tablet niche, it is now. The tech giant has just introduced Tab 4 and Tab 4 Plus models that theoretically please everyone on a budget, ranging from parents to the productivity-minded. The 8- and 10-inch editions in each range can use an optional Kids Pack (a shock-resistant case, screen protectors and a blue light filter) to ready themselves for your little one's playtime. Suddenly, Amazon's Fire HD Kids tablets have fresh competition. And if you spring for one of the 10-inch tablets, there's a Productivity Pack whose Bluetooth keyboard and matching case automatically switch you to a work-oriented mode. No one will mistake the combo for a Surface, but it should be enough to get some quick office work done.
Now that Google has officially launched Android Wear 2.0 and released its own smartwatches made by LG, it’s time for the rest of the Android Wear partners to launch new models. And the first one out of the gate is Huawei, which is refreshing its Huawei Watch from 2015 with two new, sportier models.
Last year, LG swung for the fences with the G5, taking a radical approach to the nascent world of mobile modularity. It didn’t quite work as planned, and one year later LG is moving on from the failed experiment.
LLVM/Clang 4.0 are running a few days behind schedule but should be released in the very near future. With that said, here's our usual look at the new features of this next compiler infrastructure and C/C++ compiler front-end updates.
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.
Yes, SHA-1 has been cracked, but that doesn't mean your code in Git repositories is in any real danger of being hacked.
One of the world's oldest programming styles, the ladder logic that runs on industrial programmable logic controllers, remains dangerously vulnerable to attack, according to boffins from Singapore and India.
The researchers – Naman Govil of the International Institute of Information Technology, Hyderabad; and Anand Agrawal and Nils Ole Tippenhauer of the Singapore University of Technology and Design – explain that for all the attention paid to attacks like Stuxnet, there's a dearth of work looking at what's going on at the control logic level.
