  • Welcome to the October 2019 Friends of GNOME Update!

    Molly de Blanc and Sri Ramkrishna were at All Things Open this past month. They both gave talks, ran a booth, and met lots of great people who were excited to learn about GNOME. They ran out of stickers.
    Neil McGovern and Rosanna Yuen attended GNOME.Asia Summit, both delivering keynotes! While he was in Indonesia, Neil also delivered a keynote at openSUSE.Asia Summit.
    Board member Carlos Soriano spoke at GitLab Commit about how GNOME uses GitLab.

  • Learn about our differentiated approach to IoT digital transformation at IoTSWC.

    Canonical will be present at the 2019 IoT Solutions World Congress (IOTSWC) in Barcelona from Tuesday 29th October at booth GV/P2/0/B/224.  We are convening to the flagship IoT event, alongside more than 350 leading suppliers of IoT, artificial intelligence and blockchain solutions. 

    Businesses attending IOTSWC are investing to transform their core activities with emerging digital innovations. Canonical’s mission is to empower innovators – big and small – around the world. To this end, we have developed a uniquely differentiated approach to IoT digital transformation, our goals being to accelerate delivery and boost return on investment.

    The key pillars of our differentiated approach to IoT are open-source software, cloud-native technologies, and platform ecosystems. Our IoT solutions are open source, which drives software quality thanks to community feedback, but also reduces development costs and time to market. What’s more, we are introducing cloud-native technologies like containers, Kubernetes, DevOps, and continuous delivery to the realm of IoT. Finally, we foster platform ecosystems with app stores for any IoT device. App stores enable the development of new business models and feature enhancements through applications.

  • Ubuntu Blog: Standardising software to quickly deliver a smart city platform for millions

    New York has the highest population density of any city in the United States with over 27,000 people per square mile. The average New Yorker has a commute of 40 minutes, 14 more than the national average. There are over 200 languages spoken in the city. These statistics alone illustrate the challenge of communicating to the 8.5m residents of New York to convey the latest transport, weather or security information. 

    The increased use of technology in urban infrastructure and rise of smart cities is helping to improve communications to resident New Yorkers and cities all over the world. Intersection, a US based company, specialise in using digital technology integrated into the physical world with deployments across the US and UK. Notable products include Link which launched in 2016 in New York City and now serves over 8 million Wifi users. The product was also launched in 25 cities throughout the UK, as well as Philadelphia and Newark to provide free Wifi, device charging, maps, calls and real time information such as  weather and transit information.  

    Being visible to millions of people 24/7, Intersection demand a reliable infrastructure on which to build their smart city platform. David Mitchell, of Intersection, explains the breadth of use from retail to emergency services and the challenges of introducing new technology to a variable city environment. 

    “It’s a combination of needing a platform that’s nimble but also at the scale we are running at, having to run a lot of different products while needing to make them look as consistent as possible,” David comments. 

  • Another GD32 RISC-V Development Kit with LCD By Seeed Studio

    Recently we highlighted the $5 Longan Nano, a development kit released by Sipeed for the Gigadevice GD32V RISC-V family of microcontrollers.

  • Movember 2019

    Here at SUSE, we’re a charitable bunch. I know that a few of my colleagues have grown moustaches in years gone by, and our CEO Melissa is very supportive of charity work and volunteering in general. This is my first year trying to build a team of Hairy Green Chameleons, trying to recruit men and women across the business to get involved. Whether that’s by growing a moustache, or committing to getting active with a target of completing 60km of activity over the month, to represent the 60 men that die from suicide each hour around the world. We’ve already had some very generous donations, but I hope that if you’ve read this far, you might find it in your heart to make a donation as well. If you’re a UK tax payer, then don’t forget to click the “reclaim Gift Aid on my donation” box to allow the nice folks at Movember to claim back the tax that you’ve already paid on your donation – giving them extra money at no cost to you!

  • dav1d 0.5.1 Boosts AV1 Video Decode For Older CPUs by 40~50%

    While marketed as a point release, the dav1d 0.5.1 "Asiatic Cheetah" release is quite significant for those needing to perform AV1 video decoding on older processors.

    With the dav1d 0.5.1 release there is around a 50% speed-up for those using the open-source software on SSE2 CPUs. Meanwhile for older Arm CPUs with ARMv7, there is around a 41% speed-up. There are also "minor" speed improvements for other architectures / instruction sets. Dav1d is already quite well optimized for modern CPUs with AVX and the like, so it's nice to see SSE2 and ARMv7 getting some attention.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
