  • An Open Letter to the Perl Community

    Some consider Perl 6 to be a sister language to Perl 5. Personally, I consider Perl 6 more of a genetically engineered daughter language with the best genes from many parents. A daughter with a difficult childhood, in which she alienated many, who is now getting out of puberty into early adulthood. But I digress.

  • Long Live Perl 5!

    While not mentioned in the original Letter, a frequent theme in the comments was that Perl 6 should be renamed, as the name is inaccurate or is damaging.

    This is the topic on which I wrote more than once and those who have been following closely know that, yes, many (but by no means all) in the Perl 6 community acknowledge the name is detrimental to both Perl 6 and Perl 5 projects.

    This is why with a nod of approval from Larry we're moving to create an alias to Perl 6 name during 6.d language release, to be available for marketing in areas where "Perl 6" is not a desirable name.

  • JavaScript Trends for 2018

    Trying to bet on how many new JavaScript frameworks will be released each month, is, the best software engineer’s game in the past 5 years.

  • Ick: a continuous integration system

    TL;DR: Ick is a continuous integration or CI system. See http://ick.liw.fi/ for more information.

  • Introducing PowerFake for C++

    PowerFake is a new mini-framework/tool to make it possible to fake/mock free functions and static & non-virtual member functions in C++. It requires no change to the code under test, but it might need some structural changes, like moving some parts of the code to a different .cpp file; or making inline functions non-inline when built for testing.

    It is useful for writing unit tests and faking/mocking functions which should not/cannot be run during a test case. Some say that such a feature is useful for existing code, but should not be needed for a code which is written testable from the beginning. But, personally I don’t agree that it is always appropriate to inject such dependencies using virtual interfaces or templates.

    Currently, it is not supposed to become a mocking framework on its own. I hope that I can integrate PowerFake into at least one existing C++ mocking framework. Therefore, currently it doesn’t provide anything beyond faking existing functions.

  • Introducing pylint-django 0.8.0

    Since my previous post was about writing pylint plugins I figured I'd let you know that I've released pylint-django version 0.8.0 over the weekend. This release merges all pull requests which were pending till now so make sure to read the change log.

  • nbdkit filters

    nbdkit is our toolkit for creating Network Block Device (NBD) servers from “unusual” data sources. nbdkit was already configurable by writing simple plugins in several programming languages. Last week Eric Blake and I added a nice new feature: You can now modify existing plugins by placing “filters” in front of them.

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.
