Ubuntu’s Installer Slideshow Gets a Focal Refresh

Ubuntu’s installer slideshow isn’t something most of us spend an awful time looking at but for new users it serves an important educational goal. The Ubiquity desktop installer plays a slideshow during the main part of the install process. Each slide highlights a key feature or important function available in Ubuntu (or whichever Ubuntu flavour is being installed). The slideshow has been a staple part of Ubuntu (and many flavours) since it was introduced back in Ubuntu 10.10. For the upcoming release of Ubuntu 20.04 the look of the slideshow will better match the look of Yaru, Ubuntu’s default GTK theme (which recently got a big update of its own).

Linux Mint with Windows 7 Theme

This article explains step by step to change GNU/Linux Mint operating system user interface to mimic W7 especially after its official support ended in this January 2020. You can practice this tutorial in Cinnamon Edition and you will install 2 types of theme plus 1 original wallpaper here. By this tutorial, I want to help people who find it's easier to migrate to Free Software if their desktop looks like their previous OS. I believe helping them are good and useful. And I hope by publishing this more people will come to help B00merang Project and others alike to develop these themes. I hope your switch from W7 to GNU/Linux goes easier, smoother, and perfect. Enjoy!

Kernel/Graphics: AMD, Intel and Mesa

AMD vs. Intel Contributions To The Linux Kernel Over The Past Decade

Driven by curiosity sake, here is a look at how the total number of AMD and Intel developers contributed to the upstream Linux kernel during the 2010s as well as the total number of commits each year from the respective hardware vendors. These numbers were obtained by looking at the Linux kernel commits in Git from AMD.com and Intel.com addresses. Granted, sometimes developers from both companies will use their personal email addresses rather than the corporate ones, but for this comparison is looking solely at the Git commits from the respective corporate domains.
Linux k10temp Driver For AMD CPUs Updated To Better Handle Power/Temp Analysis

As we have been eagerly talking about for the past week, the Linux kernel's k10temp driver was updated for better AMD CPU CCD temperatures and voltage/current reporting. Those improvements have been quickly evolving thanks to the work of the open-source community with AMD still sadly holding the datasheets concerning the power/temperature registers close to their vest. A new version of k10temp was sent out on Wednesday. As reported earlier this week, these k10temp improvements could land for the upcoming Linux 5.6 but additional testing is needed. While Zen 2 CPUs have been shipping for months, these k10temp improvements are only coming now thanks to HWMON maintainer Guenter Roeck who continues working on this driver in cooperation with the community as AMD currently isn't releasing documentation/datasheets concerning the power/thermal registers or any reference code for that matter... Many Linux desktop users dream of seeing something someday like AMD Ryzen Master coming to Linux.
Gutting Out Intel MPX Support To Be Finished Up In The Linux 5.6 Kernel

The Linux support for Intel MPX has already been pretty much dead since the GCC 9 compiler dropped support for MPX. Kernel developers following that began working to remove MPX from the kernel over not having the compiler support, MPX not being widely used, and also not much code movement on the kernel side. Memory Protection Extensions (MPX) was talked up years ago by Intel for allowing the checking of pointer references at run-time to avoid buffer overflows and other potential related vulnerabilities. But in reality it didn't become too popular with developers while AddressSanitizer and other compiler sanitizer infrastructure has become more used and without the need for special bits in the CPU. Intel themselves meanwhile have deprecated MPX and say the support won't be available on future CPUs, hence not being concerned much about the Linux support departing.

Mesa 20.0 branchpoint planned for 2020/01/29, Milestone opened

Hi list, due to some last minute changes in plan I'll be managing the 20.0
release. The release calendar has been updated, but the gitlab milestone wasn't
opened. That has been corrected, and is here
https://gitlab.freedesktop.org/mesa/mesa/-/milestones/9, please add any issues
or MRs you would like to land before the branchpoint to the milestone.

Thanks,
Dylan

Mesa 20.0 Feature Development Is Ending Next Week

Mesa developers are planning to end feature work on Mesa 20.0 next week as this first quarter update to the Mesa 3D graphics stack. There has been a heck of lot building up for Mesa 20.0 including many ACO optimizations, many RadeonSI and RADV improvements around GFX10/Navi, Intel Gallium3D improvements, OpenGL 4.6 with NIR by default for RadeonSI, NIR support for LLVMpipe, Vulkan 1.2 for Intel ANV and Radeon RADV, and a whole lot more... My usual feature overview will be out after the code has been branched.

SUSE/OpenSUSE: Conferences, Fonts and SUSE CaaS Platform

7 tips to survive booth duty at a conference-events

If you contribute to an open-source community, there will be an "opportunity" that you will represent the community to a conference. You're expected to staff the booth and talk to people about the software. For some people, it looks like you are traveling and having fun. I have news for you. It's not like that. We are going to see some tips on how to survive the booth duty.
https://fontinfo.opensuse.org/ updated

The information below might fall into the "unsung heroes of openSUSE" category - we think it is clearly worth to be mentioned and getting some applause (not saying that every user should owe the author a beer at the next conference ;-).
Introducing… Stratos for SUSE CaaS Platform

Would you like to make your SUSE CaaS Platform clusters simpler and more intuitive to manage? Do you want to be able to manage multiple clusters from a single pane of glass, whether on premise or in public clouds? Would you like to be able to deploy applications to your clusters, no matter whether they are in a SUSE repository, other public repositories, or your organization’s private repositories? SUSE CaaS Platform is introducing a tech preview of Stratos Console, a powerful browser-based graphical interface that delivers multi-cluster, multi-cloud management. You can assess the status and health of all of your managed clusters at a glance with multi-cluster overview dashboards, then drill down into any cluster for fine grained management of its workloads and resources.

Programming Leftovers

6 things you should be doing with Emacs

Imagine using Python's IDLE interface to edit text. You would be able to load files into memory, edit them, and save changes. But every action you perform would be defined by a Python function. Making a word all capitals, for instance, calls upper(), opening a file calls open, and so on. Everything in your text document is a Python object and can be manipulated accordingly. From the user's perspective, it's the same experience as any text editor. For a Python developer, it's a rich Python environment that can be changed and developed with just a few custom functions in a config file. This is what Emacs does for the 1958 programming language Lisp. In Emacs, there's no separation between the Lisp engine running the application and the arbitrary text you type into it. To Emacs, everything is Lisp data, so everything can be analyzed and manipulated programmatically. That makes for a powerful user interface (UI). But if you're a casual Emacs user, you may only be scratching the surface of what it can do for you. Here are six things you may not have realized you could do with Emacs.
Intersecting Intel & AMD Instruction Set Extensions

In some of my projects, I’ve recently had the need to utilize FMA (fused-multiply-add) or AVX instructions. Compiling C/C++ on X86_64 will by default only activate MXX and a few of the early SSE extensions. The utilized instruction set basically predates the core2 which was introduced in 2006. Math instructions and vectorizations can greatly benefit from more modern instructions like SSE4*, FMA, AVX, AVX2, etc, but because of the way the -march compiler option works, those are not easily enabled for all CPU types of similar age.
Intel Continues Improving Its SYCL Stack - Now Supports Ahead-Of-Time Compilation

The Khronos SYCL standard as a single-source C++-based programming model for OpenCL is one of the exciting elements for Intel's GPU compute plans with the forthcoming Xe graphics cards and fits into their oneAPI umbrella. They just released their SYCL Compiler and Runtimes 2019-12 release with numerous updates. First up this new version of their SYCL compiler/run-time features opencl-aot as a new tool for offering ahead-of-time compilation of SYCL sources. The AoT compilation tool is geared for generating device-dependent OpenCL program binaries optimized out of SPIR-V. The optimized binaries are catered for Intel's architecture.
Excellent Free Tutorials to Learn Fortran

The language is designed to be simple to understand, yet retains the efficiency in execution as assembly language – about 80% as efficient as assembly/machine code. Fortran is machine independent, and a problem oriented language. It is often used in the scientific community, particularly among physicists, and is designed for scientific numerical computing. Fortran allows for high parallelization, it’s easy to optimize, and lends itself particularly well to computationally intensive fields such as finite element analysis, numerical weather prediction, computational physics, computational chemistry, and computational fluid dynamics. Fortran has evolved over time, with various standards including Fortran IV, Fortran 77, Fortran 90 and Fortran 95. More recent revisions are Fortran 2003, and Fortran 2008. Since Fortran 9x, it has many structured programming features, dynamic memory, operator overloading, and primitive objects. It is both the language of the past, the current, and the future (high-performance computing is unlikely to cast aside Fortran). Despite its age, Fortran is still very much alive and kicking. Fortran has a vast number of libraries of code.
k-means: a brief interlude into Data Wrangling

When last we saw our heroes, what they thought was the brink of success turned out to be the precipice of hasty interpretation and now they are dangling for dear life on the branch of normalization! how's that for tortured metaphor! If you use raw values for your k-means clustering, dimensions with large values or large ranges can swamp smaller dimensions and skew your clusters. The process of normalization tries to bring everything into the same range, usually [0,1], although your choices on how to transform the ranges are also significant. There is not always one best way to do it and, as usual, get familiar with your dataset and use your judgement.
Paws XXXXIX (Very Close)

Finally things were looking my way. I plowed thought the remaining CloudFront actions and got them all to work without any more changes to Paws. In the end I checked in 30+ new tests cases and over 2k of tests the other day. So I can safely say that 'CloudFront' is fully operational. That leaves only 'Route53' to look and for me this is somewhat problematic. The Route53 api deals with 'Domains', 'Checks', 'Hosts', 'Traffic' and such.
String Formatting with Python 3's f-Strings

Python 3.6 introduced a new way to format strings: f-Strings. It is faster than other string formatting methods in Python, and they allow us to evaluate Python expressions inside a string. In this post, we'll look at the various ways we can format strings in Python. Then we'll have a deeper look at f-Strings, looking at how we can use it when displaying different data.
