HowTos

This is an user-friendly list of tools to protect user's internet privacy for Ubuntu users. The tools including search engine (StartPagec.com), add-ons (HTTPS Everywhere, Disconnect), and programs (DNSCrypt Proxy, OpenVPN) that are easy for beginners to install on Ubuntu. This list introduces the importance of privacy for all of you (yes, please read PrivacyTools.io) and that protecting your privacy is not difficult. This list is kept short so you can learn one by one and exercise them on many computers you have. I wish this helps you a lot!

  • How To Kill The Largest Process In An Unresponsive Linux System
  • Linux Academy Expands Operations to Kansas City, MO
  • Finding Files with mlocate: Part 3
  • Banana Backups

    In the September 2016 issue, I wrote an article called "Papa's Got a Brand New NAS" where I described how I replaced my rackmounted gear with a small, low-powered ARM device—the Odroid XU4. Before I settled on that solution, I tried out a few others including a pair of Banana Pi computers—small single-board computers like Raspberry Pis only with gigabit networking and SATA2 controllers on board. In the end, I decided to go with a single higher-powered board and use a USB3 disk enclosure with RAID instead of building a cluster of Banana Pis that each had a single disk attached. Since I had two Banana Pis left over after this experiment, I decided to put them to use, so in this article, I describe how I turned one into a nice little backup server.

Graphics: Mesa 17.2.6 RC, AMDGPU, and Vulkan

  • Mesa 17.2.6 release candidate
  • Mesa 17.2.6 RC Arrives With 50+ Fixes
    While Mesa 17.3 is imminent and should be released as stable within the next few days, Mesa 17.2.6 is being prepped for release as the current point release.
  • 43 More AMDGPU DC Patches Hit The Streets
    While the massive AMDGPU DC infrastructure has been merged for Linux 4.15, the flow of improvements to this display code continues and it looks like the next few kernel cycles at least could be quite busy on the AMD front.
  • A Prototype Of The Vulkan Portability Initiative: Low-Level 3D To Vulkan / D3D12 / Metal
    A Mozilla engineer has put out a prototype library in working on the Vulkan Portability Initiative for allowing low-level 3D graphics support that's backed by Vulkan / Direct3D 12 / Metal. With Apple sticking to their own Metal graphics API and Direct3D 12 still being the dominant graphics API on Windows 10, The Khronos Group has been working towards better 3D portability for where Vulkan may not be directly supported by the OS/drivers or otherwise available. They've been working to target a subset of the Vulkan API that can be efficiently mapped to these other native graphics APIs and to have the libraries and tooling for better compatibility and code re-use of these different graphics APIs.

Kernel: Linux 4.15, TLDR, and Linus Torvalds' Latest Rant

  • Linux 4.15 Adds AMD Raven Ridge Audio ID
    Not only is AMD Stoney Ridge audio (finally) being supported by the Linux 4.15 kernel, but it also looks like Raven Ridge audio should now be working too.
  • Linux 4.14.2 Fixes The BCache Corruption Bug
    Normally I don't bother mentioning new Linux kernel point releases on Phoronix unless there are some significant changes, as is the case today with Linux 4.14.2.
  • TLDR is what Linux man pages always should have been
    If you get stuck using a Linux tool, the first port of call shouldn’t be to Stack Overflow, but rather its “man pages.” Man — which is short for manual — retrieves documentation for a given program. Unfortunately, this can often be dense, hard to understand, and lacking in practical examples to help you solve your problem. TLDR is another way of looking at documentation. Rather than being a comprehensive guide to a given tool, it instead focuses on offering practical example-driven instructions of how something works.
  • Linux creator Linus Torvalds: This is what drives me nuts about IT security
    Developers are often accused of not thinking about security, but Linux kernel founder Linus Torvalds has had enough of security people who don't think about developers and end-users. After blasting some kernel developers last week for killing processes in the name of hardening the kernel, Torvalds has offered a more measured explanation for his frustration with security myopia. While he agrees that having multiple layers of security in the kernel is a good idea, certain ways of implementing it are not, in particular if it annoys users and developers by killing processes that break users' machines and wreck core kernel code. Because ultimately, if there are no users, there's not much point in having a supremely secure kernel, Torvalds contends.

Unity 7 Hoping To Become An Official Flavor For Ubuntu 18.04 LTS

While Canonical abandoned their work on the Unity desktop environment in favor of the Unity-inspired customized GNOME Shell that debuted in Ubuntu 17.10, some within the community have remained interested in maintaining Unity 7 and even getting it into an official spin/flavor of Ubuntu. Posted today to the community.ubuntu.com was a Unity maintenance roadmap, reiterating the hope by some in the Ubuntu community for Ubuntu Unity to become an official LTS distribution of Ubuntu. They are hoping to make it an official flavor alongside Kubuntu, Ubuntu Budgie, Xubuntu, and others. Read more Original/direct: Unity Maintenance Roadmap

Programming/Development: Django and Google India

  • An introduction to the Django ORM
    One of the most powerful features of Django is its Object-Relational Mapper (ORM), which enables you to interact with your database, like you would with SQL. In fact, Django's ORM is just a pythonical way to create SQL to query and manipulate your database and get results in a pythonic fashion. Well, I say just a way, but it's actually really clever engineering that takes advantage of some of the more complex parts of Python to make developers' lives easier.
