  • Sam Thursfield: Status update, 19/12/2021

    Its a time to be thankful for what you can do, rather than be pissed off about things that you can’t do because we’re in the 3rd year of a global pandemic.

    I made it home to Shropshire, in time to cast an important vote, and to spend Christmas with my folks… something I couldn’t do last year.

    Work involves a client with software integration difficulties. Our goal is to enable a Python 3 migration in the company, which involves a tangle of dependencies in various languages. The interesting aspect is that we’re trialling BuildStream as the solution. We know BuildStream can control the mix of C/C++/Go/Java/etc. dependencies, in a way which Python-only tools like virtualenv cannot, and we hope it will be less friction compared to introducing a fullblown packaging system like DPKG. The project is challenging for a number of reasons and I am not enjoying working over VPN+SSH to another continent, but I’m sure we will learn a lot.

  • The Quickest Way to Install Node.js on Ubuntu

    JavaScript is the most popular programming language among software developers, for three years in a row, according to the yearly survey conducted by Stack Overflow.

    This guide will take a look at how to install Node.js, one of the core technologies that has popularised the JavaScript language. Node.js is a JavaScript runtime environment, that allows you to create server-side or backend JavaScript applications.

  • Stock Charts Detection Using Image Classification Model ResNet

    This tutorial explores image classification in PyTorch using state-of-the-art computer vision models. The dataset used in this tutorial will have 3 classes that are very imbalanced. So, we will explore augmentation as a solution to the imbalance problem.

  • Raku Advent Calendar: Day 19 – Let it Cro

    Ah, advent. That time of year when the shops are filled with the sound of Christmas songs – largely, the very same ones they played when I was a kid. They’re a bit corny, but the familiarity is somehow reassuring. And what better way to learn about this year’s new Cro features than through the words of the Christmas hits?

    [...]

    Cro offers improved latency out of the box for thanks to setting TCP_NODELAY automatically on sockets. This disables Nagle’s algorithm, which reduces the network traffic of applications that do many small writes by collecting multiple writes together to send at once. This makes sense in some situations, but less so in the typical web application, where the resulting increased latency of HTTP responses or WebSocket messages can make a web application feel a little less responsive.

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.
