  • How Ubuntu Boosts Developer Desktop Productivity | Ubuntu

    Seventeen years after its first release, Ubuntu is firmly established as the Linux developer desktop of choice around the world. From education through to enterprise, Ubuntu delivers the tools developers need to succeed across their careers. In this blog, we will cover the main aspects that contribute to this success.

    [...]

    Developers start their careers with Ubuntu, and 69% of student developers reported that they prefer Ubuntu as an OS. It’s not surprising. With Ubuntu, they gain access to the best of open source, including AI/ML frameworks, such as Pytorch and TensorFlow, ROS for robotics and LXD and multipass for virtualisation. Open source technology is now a critical part of any enterprise, and familiarity with open source is a key consideration in hiring.

    As a result, getting new developers onboarded and productive quickly is easier with Ubuntu. It’s a system they’re familiar with. It’s flexible and customisable. And, as an operating system, it spans both the workstation and the cloud, providing a consistent development experience across your technology stack.

  • Our 12 favorite Arduino UNO projects | Arduino Blog

    The UNO wasn’t Arduino’s first board, and it won’t be its last. There have been many varieties of microcontroller and maker boards before and after the UNO, but none have been as iconic. As we cross the epic milestone of 10 million UNOs sold and the launch of the UNO Mini Limited Edition, we decided it was time to take a look back at some of our favorite UNO projects from the last 10 years.

    And we want to hear about yours, too. Join us over on social media to share your favorite UNO projects, whether you built them yourself or marveled at someone else’s electronic creation.

  • Personal computer maker Raspberry Pi plans London listing

    The company behind Britain's best-selling personal computer is preparing the ground for a spring listing which is expected to value it at more than £370m.

    The trading arm of the Raspberry Pi Foundation has hired bankers from Stifel and Liberum to advise on a London float after securing a $45m (£33m) investment in September.

    The Cambridge-based foundation offloaded stakes to Lansdowne Partners and the Ezrah Charitable Trust to fund product development and marketing after seeing booming demand for its miniature personal computers during lockdown.

  • Mozilla Privacy Blog: Mozilla files comments on UK Data Protection Consultation

    Mozilla recently submitted its comments to a public consultation on reforming the UK’s data protection regime launched by the UK Department for Digital, Culture, Media & Sport. With the public consultation, titled ‘Data: A New Direction’, the UK government set out to re-evaluate the UK’s approach to data protection after no longer being bound by the bloc’s General Data Protection Regulation (GDPR). We took this opportunity to share our thoughts on data stewardship and the role effective regulation can play in addressing the lopsided power dynamics between large data collectors and users.

    For Mozilla, privacy is not optional. It is an integral aspect of our Manifesto, which states that individuals’ security and privacy on the internet are fundamental and must not be treated as optional. This is why privacy is at the core of our product work and why we have long promoted robust data protection in our policy and advocacy work. Further, Mozilla’s Data Futures Lab is exploring alternative approaches to data governance and promoting data stewardship through original research and support to builders.

  • 42 things I learned from building a production database

    In 2017, I went to Facebook on a sabbatical from my faculty position at Yale. I created a team to build a storage system called Delos at the bottom of the Facebook stack (think of it as Facebook’s version of Chubby). We hit production with a 3-person team in less than a year; and subsequently scaled the team to 30+ engineers spanning multiple sub-teams. In the four years that I led the team (until Spring 2021), we did not experience a single severe outage (nothing higher than a SEV3). The Delos design is well-documented in two academic papers (in OSDI 2020 and SOSP 2021). Delos is currently replacing all uses of ZooKeeper at Facebook.

    Here are some of the things I learned as the tech lead for Delos. My intent in publishing this is to help others in similar roles (leading teams that are building new infra at large companies); much of it may not generalize to different settings.

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.
