  • Scaling PostgreSQL with Kubernetes Operators

    Crunchy Data's open source Crunchy PostgreSQL Operator is an Operator for PostgreSQL that is used in many production environments. It provides a simple yet powerful command-line interface that lets users deploy their own database-as-a-service system on any Kubernetes-enabled platform.

    For example, with the pgo create command, which is used to provision a database, you can set up a distributed, high-availability PostgreSQL cluster with full disaster recovery support along with a database monitoring sidecar powered by pgMonitor. In other words, in lieu of a complicated multi-step process or having to write your own scripts, you can create the type of PostgreSQL system required for production from a single command.

    While this may seem to be overkill if you are managing a handful of database clusters, the value of an Operator scales significantly if you need to support hundreds or thousands of different clusters. Having a standardized set of commands with the ability to flexibly deploy clusters for different workloads both eases the administration burden and provides more options for how a team can develop and deploy workloads into production.

  • Today's Context Demands Use of OER

    This movement is the most exciting thing to happen to higher ed in my lifetime. It brings together the humanity, respect for students (and instructors!) and impetus to make a positive change in students’ lives from thinkers like bell hooks, Paulo Freire and John Dewey with the technological know-how and thirst for openness, access and justice of Seymour Papert, Richard M. Stallman and Aaron Swartz.

    There is no point in my parodying the eloquence of the expositors of open pedagogy cited above -- please go read them right now, if you haven’t yet. But one thing I can do is add a small point I haven’t see those authors emphasize, in the spirit (following Green) of exploring what motivates faculty. One thing that faculty members love (perhaps particularly at primarily research institutions, where they may be worried about something with enormous impact on pedagogy but which will require a large investment of their time) is their academic freedom.

  • AMDGPU LLVM Backend Seeing A Number Of Fixes In Recent Days

    If you habitually use the latest open-source graphics drivers, you may want to pull down the latest LLVM code from SVN/Git as there has been a number of fixes to the AMDGPU back-end in recent days.

    For those that haven't upgraded in a while or perhaps still on the LLVM 8 code-base, the latest LLVM 9 development code has been seeing a number of AMDGPU commits during the second half of February. There's been enabling of function calls by default that fixes some crashes, other crash fixes, implementing various features, enabling the DPP combiner pass by default, and other bits.

  • Include the currency name into the forex application

    Hello and welcome back to this new python forex application project. In the previous chapter, we have successfully retrieved the name and the id pair for all the conbase supported currencies, and in this chapter, we will use that information to add the currency name beside each currency id when we are comparing that currency to the USD. Below is the modify version of this program.

  • IRC vs IRL: How to run a good IRC meeting

    There's an art to running a meeting in any format. Many people have learned to run in-person or telephone meetings, but Internet Relay Chat (IRC) meetings have unique characteristics that differ from "in real life" (IRL) meetings. This article will share the advantages and disadvantages of the IRC format as well as tips that will help you lead IRC meetings more effectively.

    Why IRC? Despite the wealth of real-time chat options available today, IRC remains a cornerstone of open source projects. If your project uses another communication method, don't worry. Most of this advice works for any synchronous text chat mechanism, perhaps with a few tweaks here and there.

Graphics: AMD, GNOME Shell on Wayland and NVIDIA Nsight Graphics

  • AMD Pushes Back 3rd Gen Threadripper & Ryzen 9 3950X Until November

    While the Ryzen 9 3950X and 3rd Gen Ryzen Threadripper processors were reportedly on track for launching in October with updates as of a few weeks ago, today AMD announced a slight delay in launching these new processors.

  • AMD have delayed the Ryzen 9 3950X and 3rd generation Threadripper until November

    Today, AMD sent out a brief statement about a delay in their 16 core Ryzen 9 3950X and the 3rd generation Threadripper. [...] So if you were looking to grab either, keep an eye out in November. Will share any more news when they send it about the expected date and pricing.

  • AMD Sends In Initial Batch Of Fixes To Linux 5.4 - Includes Dali Support

    While just yesterday the big DRM feature pull was sent in for Linux 5.4, AMD has also volleyed out their initial batch of fixes for this next version of the kernel. This new AMDGPU pull isn't strictly fixes but as anticipated does include the recently reported Dali APU support. Dali along with Renoir -- also newly-supported in Linux 5.4 -- are some of AMD's 2020 APUs. Dali will be targeting the lower-end of the spectrum it's expected for value mobile/embedded. From the driver code, Dali looks like a newer revved version of the current-gen Picasso APUs. Both Dali and Renoir are based on the Vega architecture.

  • Linux Plumbers Conference 2019, part 2

    Pain points and missing pieces with Wayland, or specifically GNOME Shell: GNOME Shell is slower Synergy doesn't work(?) - needs to be in the compositor With Nvidia proprietary driver, mutter and native Wayland clients get GPU acceleration but X clients don't No equivalent to ssh -X. Pipewire goes some way to the solution. The whole desktop can be remoted over RDP which can be tunnelled over SSH. No remote login protocol like XDMCP No Xvfb equivalent Various X utilities that grab hot-keys don't have equivalents for Wayland Not sure if all X's video acceleration features are implemented. Colour format conversion and hardware scaling are implemented. Pointer movement becomes sluggish after a while (maybe related to GC in GNOME Shell?) Performance, in general. GNOME Shell currently has to work as both a Wayland server and an X compositor, which limits the ability to optimise for Wayland.

  • NVIDIA's Nsight Graphics 2019.5 Released With Better Vulkan Coverage

Ubuntu: Video Encoder Performance, Ubuntu Touch, LZ4 Compression

  • Clear Linux vs. Ubuntu 19.10 Video Encoder Performance On The Core i9 9900K

    Often when doing cross-distribution benchmarks, readers often comment on the performance of Clear Linux particularly for video encoding use-cases as surprisingly different from other distributions. Some argue that it's just over the default CPU frequency scaling governor or compiler flag defaults, so here is a look at that with Ubuntu 19.10 daily benchmarked against Clear Linux. On the same Core i9 9900K system I recently ran some benchmarks looking at Clear Linux vs. Ubuntu 19.10 and then Ubuntu 19.10 with various common tunables to make it more akin to Clear Linux. Ubuntu 19.10 was used due to its recent software components being at similar versions to Intel's rolling-release distribution.

  • Serge Hallyn: First experience with Ubuntu Touch

    For the past few weeks I’ve been using a nexus 4 running ubuntu touch as, mostly, my daily driver. I’ve enjoyed it quite a bit. In part that’s just the awesome size of the nexus 4. In part, it’s the ubuntu touch interface itself. If you haven’t tried it, you really should. (Sailfish ambiances are so much prettier, but ubuntu touch is much nicer to use – the quick switch to switch between two apps, for instance. Would that I could have both.). And in part it’s just the fact that it really feels like – is – a regular ubuntu system.

  • Ubuntu 19.10 to use LZ4 compression to boot even faster

    anonical’s Ubuntu 19.10 “Eoan Ermine” will boot even faster than its predecessor, Ubuntu 19.04 “Disco Dingo” according to Ubuntu’s kernel team. After extensive testing on a variety of compression options on the Ubuntu installation image, Canonical engineers determined that the LZ4 decompression method provided a most appreciable gain in speed.

The Vivaldi 2.8 Release (Proprietary)

  • New Version Vivaldi Web Browser Has Been Released, Install in Ubuntu/Linux

    Vivaldi is the new web browser compare to other famous browsers, the initial release of Vivaldi was in January, 2015. It has improved a lot and evolved since the first release. Basically it is based on the open-source frameworks of Chromium, Blink and Google's V8 JavaScript engine and has a lot of great feature which I will table later. It is known to be the most customizable browser for power users, debuts features that make browsing more personal than ever before. Do we really need another browser? Since we already have a lot of them such as mostly used Firefox, Chrome, Opera and so on. The former CEO of Opera Software Jon Von Tetzchner didn't liked the direction of Opera Web Browser and said "Sadly, it is no longer serving its community of users and contributors - who helped build the browser in the first place." Then created a web browser which has to be fast, rich feature, highly flexible and puts the user first, so Vivaldi was born.
