  • Gleam v0.14 released!

    Many dynamically typed BEAM languages support Erlang’s typespecs, type annotations that can be analysed with the Dialyzer tool. While not as powerful or reliable as Gleam’s type system it can be a useful tool for finding problems with your Erlang or Elixir code. Dialyzer doesn’t require typespecs but it can work better if they are added to the code.

    Starting with this release Gleam will generate typespecs for all functions and Erlang type definitions for all declared types within a Gleam program, giving you one extra tool to help you write robust and reliable code when using Gleam alongside Elixir or Erlang.

  • A year of Rails

    This was a really fun experience. There’s a lot to love about Rails. Other communities could learn a bit from the Ruby & Rails culture and wisdom. I won’t implement everything in Rails, but it’ll be part of the toolbox.

    Before this, I hadn’t touched the stuff. And I bet a lot of people are like that - they came of age in the world of React and Go, and haven’t tried anything even remotely similar to Rails. For their benefit, and to debrief from 2020, here are some notes on the experience. Plus, Rails-like projects in JavaScript are ramping up quickly, and it’s fun to know the origins.

  • Why is it so hard to see code from 5 minutes ago?

    A study found that Java developers backtracked every 6 minutes, meaning they reverted their code to a previous state (e.g., by clicking undo or pressing Ctrl-Z).1 These undo actions come in bursts and are often followed by successive redo actions. In fact, one participant in a different study used undo/redo 40 times in 5 minutes!2 When asked why they did this, they revealed they were trying to view some intermediate state of the code in the middle of a change.

  • Cybersecurity Is Like Food Safety: Digital HACCP

    There are lots of calls to invest in improving cybersecurity.

    But it struck me that it doesn’t work like that. Not getting [cracked] is not so much a question of buying the right stuff. It is a question of doing the right things and understanding what you are doing.

    It is easy to demand that people ‘invest’ in something. You can even supply them with the money to do so. But that doesn’t mean that it will help. You can’t just apply more armor and be ‘cyber secure’.

    A very useful analogy is food safety. We’re all aware how handling chicken badly can seriously imperil the health of the people you cook for.

    In fact, we’re so aware that we created stringent rules for professional kitchens, including inspections and investigations after incidents.

    Over the years, we’ve gotten a lot better at food safety, and it now extends down the entire supply chain, “from farm to fork”.

  • The 10 Best AI and Machine Learning Programming Languages

    The world saw some big and remarkable discoveries in the 20th century. Artificial Intelligence is one of them. There was a time when AI and Machine Learning(ML) could not be applied due to a lack of computing power. But today’s computers are robust enough to handle Machine Learning algorithms. That’s why AI and ML are ruling in almost every field. Machine Learning and AI is a valuable skill now. However, to use it, you have to learn a specific programming language from various Artificial Intelligence and Machine Learning programming languages. Today we will assist you in picking an appropriate programming language to work in this field.

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.
