  • Dirk Eddelbuettel: littler 0.3.15 on CRAN: Package Updates

    The sixteenth release of littler as a CRAN package just landed, following in the now fifteen year history (!!) as a package started by Jeff in 2006, and joined by me a few weeks later.

    littler is the first command-line interface for R as it predates Rscript. It allows for piping as well for shebang scripting via #!, uses command-line arguments more consistently and still starts faster. It also always loaded the methods package which Rscript only started to do in recent years.

    littler lives on Linux and Unix, has its difficulties on macOS due to yet-another-braindeadedness there (who ever thought case-insensitive filesystems as a default were a good idea?) and simply does not exist on Windows (yet – the build system could be extended – see RInside for an existence proof, and volunteers are welcome!). See the FAQ vignette on how to add it to your PATH. A few examples are highlighted at the Github repo, as well as in the examples vignette.

  • Cdson

    Today, I'm announcing the release of my library cdson: a parser and serializer for the DSON data format in C. (As the name suggests, DSON is a bit like JSON, and I strongly prefer its usage to YAML.) While I'm many years late to this joke, in that time somehow no one had implemented a DSON library in C.

    [...]

    cdson takes this last route. 18 bits of code point is planes 1-3, which is actually everything except private use and alternate reps right now. But it also gates using \\u-escapes at all behind a flag.

    Writing cdson has amused me, but having finished the project does not mean the amusement must cease. cdson is open source software under the very permissive MPL; feel free to add it to projects if doing so would amuse you too. And if you need a defensible config file format, might I recommend anything that's not YAML?

  • Writing a SNES assembler compiler/disassembler - Day 1

    Why ? Because I can. More seriously I have a project where I need to inject new Snes code in a running game and I want to express directly this new code in my Raku component (A webserver service). I want to have special sub that returns me Snes bytecode but that contains Snes assembler.

    I tried injecting a SLANG in Raku already. Like writing my $byte-code = SNES lda $42; sta $54; rtl; But it’s rather tricky and I will probably just have a additional Slang with its own grammar in a dedicated file.

  • 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.
