Linux Kernel 4.4.23 LTS Has ARM and MIPS Improvements, Updated Filesystems, More
Immediately after announcing the release of Linux kernel 4.7.6, Greg Kroah-Hartman proudly informed the community about the general availability of the Linux 4.4.23 LTS kernel.
The Linux 4.4 kernel is a long-term supported branch, the latest and most advanced one, used in many stable and reliable GNU/Linux operating systems, including Ubuntu 16.04 LTS (Xenial Xerus) and Alpine Linux 3.4. Therefore, it is imperative for it to receive regular updates that bring fixes to the most important issues, as well as other general improvements.
From NFS to LizardFS
If you’ve been following me for a while, you’ll know that we started our data servers out using NFS on ext4 mirrored over DRBD, hit some load problems, switched to btrfs, hit load problems again, tried a hacky workaround, ran into problems, dropped DRBD for glusterfs, had a major disaster, switched back to NFS on ext4 mirrored over DRBD, hit more load problems, and finally dropped DRBD for ZFS.

BUS1, The Successor To KDBUS, Formally Unveiled -- Aiming For Mainline Linux Kernel
BUS1 has been in development as an in-kernel IPC mechanism building off the failed KDBUS project. An "RFC" will soon be sent out to Linux kernel developers about BUS1 and the subject will be discussed at next month's Kernel Summit.
David Herrmann, one of the BUS1 developers, presented at this week's systemd.conf conference about the new capability-based IPC for Linux. He talked about how BUS1 is superior to KDBUS, how BUS1 is similar to Android's Binder, Chrome's Mojo, Solaris' Doors, and other common IPC implementations.
A New Wireless Daemon Is In Development To Potentially Replace wpa_supplicant
In addition to the BUS1 presentation, also exciting from the systemd.conf 2016 conference is a thorough walkthrough of a new wireless daemon for Linux being developed by Intel's Open-Source Technology Center.
Intel has been developing a new wireless daemon for Linux to potentially replace wpa_supplicant. This new daemon isn't yet public but the code repositories for it will be opened up in the next few weeks. This new daemon has improvements around persistency, WiFi management, reduced abstractions for different operating systems and legacy interfaces, and changes to operation. This daemon is designed to be very lightweight and work well for embedded Linux use-cases especially, including IoT applications.

An Easy Way To Try Intel & RADV Vulkan Drivers On Fedora 24
Fedora 25 should have good support for the open-source Vulkan Linux drivers (particularly if it lands the next Mesa release) while Fedora 24 users can now more easily play with the latest Mesa Git RADV and Intel ANV Vulkan drivers via a new repository.
A Phoronix reader has setup a Fedora Copr repository that is building Intel's Vulkan driver from Mesa Git plus the RADV Radeon Vulkan driver re-based from its source (David Airlie's semi-interesting GitHub branch). Fedora COPR, for the uninformed, is the distribution's equivalent to Ubuntu PPA repositories.
Meeting users, lots of users
Every year, I introduce Fedora to new students at Brno Technical University. There are approx. 500 of them and a sizable amount of them then installs Fedora. We also organize a sort of installfest one week after the presentation where anyone who has had any difficulties with Fedora can come and ask for help. It’s a great opportunity to observe what things new users struggle with the most. Especially when you have such a high number of new users. What are my observations this year?

Yahoo open-sources a deep learning model for classifying pornographic images
Yahoo today announced its latest open-source release: a model that can figure out if images are specifically pornographic in nature.
The system uses a type of artificial intelligence called deep learning, which involves training artificial neural networks on lots of data (like dirty images) and getting them to make inferences about new data. The model that’s now available on GitHub under a BSD 2-Clause license comes pre-trained, so users only have to fine-tune it if they so choose. The model works with the widely used Caffe open source deep learning framework. The team trained the model using its now open source CaffeOnSpark system.
The new model could be interesting to look at for developers maintaining applications like Instagram and Pinterest that are keen to minimize smut. Search engine operators like Google and Microsoft might also want to check out what’s under the hood here.
“To the best of our knowledge, there is no open source model or algorithm for identifying NSFW images,” Yahoo research engineer Jay Mahadeokar and senior director of product management Gerry Pesavento wrote in a blog post.

New alliances focus on open-source, data science empowerment
How can data science make a true market impact? Partnerships, particularly amongst open source communities. As IBM solidifies its enterprise strategies around data demands, two new partnerships emerge: one with Continuum Analytics, Inc., advancing open-source analytics for the enterprise; and another with Galvanize, initiating a Data Science for Executives program.
Continuum Analytics, the creator and driving force behind Anaconda — a leading open data science platform powered by Python — has allied with IBM to advance open-source analytics for the enterprise. Data scientists and data engineers in open-source communities can now embrace Python and R to develop analytic and machine learning models in the Spark environment through its integration with IBM’s DataWorks Project.
The new agreement between IBM and Galvanize, which provides a dynamic learning community for technology, will offer an assessment, analysis and training element for Galvanize’s Data Science for Executives program. This program empowers corporations to better understand, use and maximize the value of their data. The program will support IBM’s DataFirst Method, a methodology that IBM says provides the strategy, expertise and game plan to help ensure enterprise customers’ succeed on their journey to become a data-driven business.

- Friday's security advisories
ICANN grinds forward on crucial DNS root zone signing key update
The Internet Corporation for Assigned Names and Numbers is moving -- carefully -- to upgrade the DNS root zone key by which all domains can be authenticated under the DNS Security Extensions protocol.
ICANN is the organization responsible for managing the Domain Name System, and DNS Security Extensions (DNSSEC) authenticates DNS responses, preventing man-in-the-middle attacks in which the attacker hijacks legitimate domain resolution requests and replaces them with fraudulent domain addresses.
DNSSEC still relies on the original DNS root zone key generated in 2010. That 1024-bit RSA key is scheduled to be replaced with a 2048-bit RSA key next October. Although experts are split over the effectiveness of DNSSEC, the update of the current root zone key signing key (KSK) is long overdue.
Cybersecurity isn't an IT problem, it's a business problem
The emergence of the CISO is a relatively recent phenomenon at many companies. Their success often relies upon educating the business from the ground up. In the process, companies become a lot better about how to handle security and certainly learn how not to handle it.
As a CIO, knowing the pulse of security is critical. I oversee a monthly technology steering committee that all the executives attend. The CISO reports during this meeting on the state of the security program. He also does an excellent job of putting risk metrics out there, color coded by red, yellow, and green. This kind of color grading allows us to focus attention on where we are and what we’re doing about it.

Best Android Phone Under $700
The Galaxy S7 is the best version of Samsung's flagship yet. It's equipped with a powerful Qualcomm Snapdragon 820 processor, 4GB of RAM, and a 3,000mAh battery pack. Its 12-megapixel rear-facing Dual Pixel camera is particularly impressive, and you'll appreciate its performance in low light.
Of course, as is the case with most versions of Android that aren't directly developed by Google, Samsung's version of Android is polarizing. The newly dubbed Grace UI offers some helpful features, but the extra software that comes bundled is redundant. At the very least, you can disable and hide any apps you don't care for.
Best Android Phones with Expandable Memory
The Galaxy S7 edge is the total package. The phone features a stunning metal-and-glass exterior backed by an excellent 5.5-inch display. The dual curved display is easily one of the best you'll find on a phone, and differentiates the S7 edge from the pack. The handset is powered by Qualcomm's beastly Snapdragon 820 SoC, and offers 4GB of RAM along with 32GB storage. The 12MP camera is outstanding, and the 3600mAh battery ensures you get at least a day's worth of usage from a full charge.
Best of all, Samsung re-introduced the microSD slot after leaving it out on the Galaxy S6 series. The phone accommodates microSD cards up to 256GB, which should be more than sufficient for all your movie or music needs. If all that isn't enough, the S7 edge is water resistant with an IP68 rating.
