Programming and Interoperability Leftovers

  • Please stop writing shell scripts

    That’s when you realize your mistake: bash, and shell scripting languages in general, are mostly broken by default. Unless you are very careful from day one, any shell script above a certain complexity level is almost guaranteed to be buggy… and retrofitting the correctness features is quite difficult.

  • How to Use R and Python Together? Try These 2 Packages

    Data science is vastly different than programming. We use only four languages – R, Python, Julia, and SQL. Now, SQL is non-negotiable, as every data scientist must be proficient in it. Julia is still the new kid on the block. Many argue which is better – Python or R? But today, we ask a different question – how can you use R and Python together?

    It might seem crazy at first, but hear us out. Both Python and R are stable languages used by many data scientists. Even seasoned package developers, such as Hadley Wickham, borrow from BeauftifulSoup (Python) to make Rvest (R) web scraping packages. Reinventing the wheel makes no sense.

  • Version of Perl I use, via @pinkopanterata

    I’m still on Perl 5. I had fun exploring Raku, but Perl 5 still does everything I want, and uses that familiar syntax. I haven’t touched Perl 7 yet, but that’s on the personal project pile.

  • Tables and Strings in COBOL

    I recently came across a blog post dealing briefly with the concept of strings, tables and subscripting in COBOL. While the code in the blog post works just fine, I personally think it's overcomplicating a very simple use case (subscripting a string) and underselling a powerful COBOL feature (tables). Since I'm a deeply demented man with a lot of free time on my hands, I decided to expand a bit on the subject - if only to give myself a chance of brushing up on my own very rudimentary COBOL knowledge. Feel free to point out any errors.

  • I finally found a use for XML

    Changing the boilerplate sucks though. If I make any tweaks to the initial version of the code, I have to manually change every single file to keep them all in sync. With just a first and final version that’s not too bad, but if I have four intermediates that gets tiring really fast.

  • A conversation about Interoperability and building digital public spaces

    Interoperability is one of the original design principles underpinning the internet, and largely responsible for its scale and unique properties. In recent years, it has also been increasingly seen as a policy measure that can introduce greater market competition and user choice. Important, and contentious interoperability proposals are included in key European digital regulations, including the Digital Markets Act and the Data Act.

  • A Big Bet to Kill the Password for Good

    After years of tantalizing hints that a passwordless future is just around the corner, you're probably still not feeling any closer to that digital unshackling. Ten years into working on the issue, though, the FIDO Alliance, an industry association that specifically works on secure authentication, thinks it has finally identified the missing piece of the puzzle.

    On Thursday, the organization published a white paper that lays out FIDO's vision for solving the usability issues that have dogged passwordless features and, seemingly, kept them from achieving broad adoption. FIDO's members collaborated to produce the paper, and they span chipmakers like Intel and Qualcomm, prominent platform developers like Amazon and Meta, financial institutions like American Express and Bank of America, and the developers of all major operating systems—Google, Microsoft, and Apple.

    The paper is conceptual, not technical, but after years of investment to integrate what are known as the FIDO2 and WebAuthn passwordless standards into Windows, Android, iOS, and more, everything is now riding on the success of this next step.

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.
