  A constant is a constant and it’s constantly the same.

• James G ☛ Imperfect programs

  Earlier today, I wrote a program that generates a trading card for a web site. The program downloads a web page, retrieves meta information about it, and formats the information into a trading card style. The way I made the program was less elegant than I conceived in my head. I thought about an elaborate script that would parse an SVG file I made in a design tool and generate text, until I learned that what I thought was the best way was more complex than expected.

  By this point, I had a design for a trading card in a design tool, Figma. I didn't want to lose the design, since it was just right and I was proud of the design I made. Thus, I used a plugin to export the data to HTML. The export was not perfect: the page was divs, but readable and understandable by me, and parsable by a computer. Thus, the HTML was fit for purpose.

• Perl / Raku

  • Rakulang ☛ Rakudo 2024.18 Over The Finish Line

    Raku Core developer and Raku Steering Council member Stefan Seifert has submitted a Grant Proposal to accelerate the development of RakuAST continuing in the footsteps of Jonathan Worthington. A worthy cause! The Raku Community is invited to comment on this proposal (or at /r/rakulang).

  • Rlang ☛ Guide to Remove Legends in ggplot2 in R Programming

    The data visualization with R, ggplot2 reigns supreme. However, a well-designed legend from a plot can undermine even the most elegant plots. Legends have the power to clarify or confuse – they're the key that unlocks the insights hidden within your graphs.

  • Rlang ☛ Visualizing Power Models in Species-Area Relationships Using R Shiny: An Interactive Educational Tool

    Considered one of the “few general rules” in ecology, the species-area relationship (SAR) – the ubiquitous pattern indicating that larger islands or habitat patches harbor more species than smaller ones – has played a pivotal role in shaping ecological theories (Lomolino 2000, 2001, Tjørve 2003, 2009, Dias et al. 2020).

  • Pete Zaitcev: Export to STEP in OpenSCAD

    The only way to obtain STEP from OpenSCAD that I know is an external tool that someone made. It's pretty crazy actually: it parses OpenSCAD's native export, CSG, and issues commands to OpenCASCADE's CLI, OCC-CSG. The biggest issue for me here is that his approach cannot handle transformations that the CLI does not support. I use hull all over the place and a tool that does not support hull is of no use for me.So I came up with a mad lad idea: just add a native export of STEP to OpenSCAD. The language itself is constructive, and an export to CSG exists.
