  • snekde — an IDE for snek development

    I had hoped to create a stand-alone development environment on the Arduino, but I've run out of room. The current snek image uses 32606 bytes of flash (out of 32768) and 1980 bytes of RAM (out of 2048). I can probably squeeze a few more bytes out, but making enough room for a text editor seems like a stretch.

    As a back-up plan, I've written a host-side application that communicates with the Arduino over the serial port.

  • 3 new ways to contribute code to Ansible

    Here are the three ways that have me excited for would-be contributors to the Ansible community.

  • Introducing the Small Scale Scrum framework

    Scrum is a leading candidate for the implementation of Small Scale Agile for many reasons, including its popularity, developers’ preferences, high success rates for scrum adoption and project deliveries, and strong principles and values including focus, courage, openness, commitment, and respect.

    Small Scale Scrum can be best described as “a people-first framework defined by and for small teams (a maximum of three people) and supporting planning, developing, and delivering production-quality software solutions.” The proposed framework centers around the concept of team members occupying multiple roles on any project.

    Small Scale Scrum is valuable due to its strong support for the small, distributed teams found in organizations all over the world. Small teams need new ways to meet customers’ continuously growing expectations for rapid delivery and high quality, and Small Scale Scrum’s guidelines and principles help address this challenge.

  • GCC 8/9 vs. LLVM Clang 7/8 Compiler Performance On AArch64

    With Clang 8.0 due out by month's end and GCC 9 due for release not long after that point, this week we've been running a number of GCC and Clang compiler benchmarks on Phoronix. At the start of the month was the large Linux x86_64 GCC vs. Clang compiler benchmarks on twelve different Intel/AMD systems while last week was also a look at the POWER9 compiler performance on the Raptor Talos II. In this article we are checking out these open-source compilers' performance on 64-bit ARM (AArch64) using an Ampere eMAG 32-core server.

  • How Clear Linux Optimizes Python For Greater Performance

    Clear Linux's leading performance isn't limited to just C/C++ applications but also scripting languages like PHP, R, and Python have seen great speed-ups too. In a new blog post, one of Intel's developers outlines some of their performance tweaks to Python for delivering greater performance.

    Last April, Victor Rodriguez Bahena of the Intel Open-Source Technology Center and longtime Clear Linux developer began shedding more light on their "magic" performance work for the distribution's out-of-the-box performance. Finally this week the second post in that series is out as he details the optimizations made to their Python implementation.

  • Qt 5.13 Alpha Released With WebAssembly Preview, Qt Lottie Technical Preview

    The Qt Company has announced the alpha release of the forthcoming Qt 5.13 tool-kit.

    Qt 5.13 is slated for release in May and is another Qt5 feature release ahead of the transition to Qt6 planned for late 2020.

  • Qt 5.13 Alpha Released

    I am happy to inform that Qt 5.13 Alpha is released today. You can download Qt 5.13 Alpha via online installer (both source and prebuild binary packages). Source packages are also available for commercial users in the Qt Account portal and in the download.qt.io for open-source users.

    Qt 5.13 New Features page contains information about most important changes coming with the release. Please remember creating the list is still in progress so something important can still be missing. List should be completed by Beta1.

    Target is to release Beta1 within coming weeks, when API reviews are concluded. And as with previous releases we will release regular beta n releases until we are ready for RC. Target for Beta1 is 26.2.2019, see whole schedule from Qt 5.13 wiki.

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.
