  • Telco cloud: what is that? | Ubuntu

    Telco cloud or a network function virtualisation infrastructure (NFVI) is a cloud environment optimised for telco workloads. It is usually based on well-known technologies like OpenStack. Thus, in many ways, it resembles ordinary clouds. On the other hand, however, it differs from them. This is because telco workloads have very specific requirements. Those include performance acceleration, high level of security and orchestration capabilities. In order to better understand where those demands are coming from, let’s start with reviewing what kind of workloads are telcos running in the cloud.

  • OpenStack at 10 – from peak to plateau of productivity | Ubuntu

    This week is the latest Open Infrastructure Summit, in a week where the OpenStack Foundation became the Open Infrastructure Foundation to reflect the expansion of the organisation’s mission, scope and community to advance open source over the next decade to support open infrastructure. It is also ten years since OpenStack launched and a lot has changed during that time. We asked freelance journalist, Sean Michael Kerner, to share his views on the last ten years. Sean is a freelance journalist writing on myriad IT topics for publications around the world. He has spoken at more OpenStack events than he cares to remember. English is his second language (Klingon his first). Follow him on Twitter @TechJournalist. 10 years ago in July 2010, I got an unusual pitch from a PR person. It was the beginning of a long and winding road that defines my experience and viewpoint on OpenStack. Unlike the usual spate of product and open source pitches from vendors that I got at the time (and still get), the pitch I got on the sunny July afternoon was an offer to speak with the CTO of IT at NASA. It was an offer I couldn’t refuse – and I suspect it’s also the reason why OpenStack got so much attention early on – it was literally ‘rocket science’. In a 2012 video interview I did with Chris Kemp after he left the role of CTO at NASA to start his own OpenStack startup, he told me that in his view OpenStack could well become one of NASA’s great contributions to society.

  • Canonical & Ubuntu at KubeCon NA Virtual 2020 | Ubuntu

    By now it’s no surprise that KubeCon NA is going virtual, like the majority of events worldwide. Is that bad news? Quite the opposite! According to CNCF, this year’s KubeCon EU – the first KubeCon to ever be hosted virtually – made it possible for over 18,700 Kubeheads to sign up, 72% of which were first-time KubeCon + CloudNativeCon attendees. In other words, as we have all believed for so many years now, tech is helping the community grow and get closer.

  • Production-Ready Notebooks for End-to-End ML Workflows With Kubeflow

    Machine Learning projects consist of several distinct steps: first, data validation verifies the state of the collected data. Processing prepares the features so an algorithm can consume them. Model training makes learning feasible, and model validation guarantees generalization. Fine-tuning adjusts the hyper-parameters to obtain the optimum results. Finally, after numerous iterations, the last step deploys a model to staging or production. Each of these steps can be a separate process, running at its own cadence, with well-defined inputs and outputs. Thus, data scientists and ML engineers tend to think of these projects like pipelines. If there is something wrong with incoming information, the process could fail or even worse corrupt downstream analytic tasks. Thus, standardizing the process of creating these interconnected actions can make the pipeline more robust. In this article, we demonstrate how to turn Jupyter Notebooks into Kubeflow Pipelines and Katib Experiments automatically. Such a system eliminates the erroneous process of manually extracting the bits that make sense in a Notebook, containerize them and launching a Pipeline using explicit Domain-Specific Languages.

  • Support for Istio 1.6 ends on November 21st, 2020

    According to Istio’s support policy, LTS releases like 1.6 are supported for three months after the next LTS release. Since 1.7 was released on August 21st, support for 1.6 will end on November 21st, 2020. At that point we will stop back-porting fixes for security issues and critical bugs to 1.6, so we encourage you to upgrade to the latest version of Istio (1.7.3). If you don’t do this you may put yourself in the position of having to do a major upgrade on a short timeframe to pick up a critical fix.

  • Cloud Foundry Foundation Announces Project Updates

  • How to Turn Your Raspberry Pi into a Video Conferencing Station - Make Tech Easier

    With the advent of working and schooling from home, more people are turning toward video conferencing as a way to get things done. Using tools like Google Meet and Zoom, we can keep in touch with people across cities, time zones, and even countries and continents, making the world much smaller and allowing for collaboration in ways we never thought of before. However, if you’re looking for another great Raspberry Pi project, I can’t recommend a video conferencing station enough. In this tutorial we show you how to turn your Raspberry PI into a video conferencing station.

  • Magento Tips & Tricks for Better Performance - RoseHosting

    Most web hosting providers provide either Linux or Windows server hosting. The type of operating system you need depends on what kind of language and database you plan to use with your website. Linux is a command-line operating system and everything on it, including PHP should (and almost always does) work better on Linux. Linux is a free and secure operating system and provides ready-to-use software to power your website.

  • The Steam Digital Tabletop Fest is now live with sales, streams and more | GamingOnLinux

    Ready to fill your Steam Library full of awesome games once again or perhaps try out a demo or two? You might want to pull up a seat to the digital table then, as the Steam Digital Tabletop Fest is now live. This special event features nearly 40 hours of livestreams, virtual let's plays, panels, talks and so much more. The idea, done in partnership with Auroch Digital is to show off games that "explore the fusion between physical and digital games". For this event, they even made a trailer which is pretty unusual and goes to show how much Valve has changed over the years as they continue working with more developers on events like this. This is actually one of the biggest events I believe they've ever done.

  • Fast, challenging and you can run up walls to slice up enemies - ScourgeBringer is out | GamingOnLinux

    ScourgeBringer is a fast-paced action rogue-lite that has you run from room to room slicing and dicing through enemies, and it makes you feel awesome. Flying Oak Games, who previously made NeuroVoider, describe it as a "free-moving roguelite platformer" which doesn't really do it much justice. You're one of the last surviving humans, fighting through the ScourgeBringer, some kind of almighty weapon with a whole lot of random rooms inside which for some unknown reason decided to decimate the world. You given a big sword, a gun and then sent on your way to save everyone and perhaps redeem humanity. So, no pressure then right?

  • Godot Engine - Dev snapshot: Godot 3.2.4 beta 1

    Godot 3.2.3 was released a month ago and the reception was great! It focused mostly on fixing bugs and therefore we were somewhat conservative on what could be merged before the release. Now that we're confident that 3.2.3 works well, we can take some time to add new features to the 3.2 branch while you wait for Godot 4.0 :)

5 Best Free and Open Source Console Web Browsers

A web browser is the quintessential desktop application. Everyone needs one, and there is not a desktop Linux distribution around that does not make a web browser available. This type of software application is responsible for retrieving and presenting information held on the World Wide Web, a system of interlinked hypertext documents accessed via the internet. Web browsers allow users to view web pages which often contain a mixture of text, images, videos, and other multimedia. Read more
