Testing Fountain Pen Inks

Question: has anyone done extensive testing on any fountain pen inks?

I don’t mean the standard Mountain of Ink style, sample card, writing sample, etc. visual comparisons. (I’d like to call this subjective measurement, but chromatographic measurements aren’t subjective if done in a controlled manner.)

I am thinking more objective testing: viscosity, density, flow rate @ a given line width, etc.

I was thinking about this type of testing tonight, and it seems to me that there are a lot of factors that would need to be controlled: temperature, air pressure / barometric pressure, nib consistency, friction (aka heat), etc. Given what I was thinking this could be an interesting experiment, if someone wanted to undertake controlling all the variables, and implementing the controls necessary for consistent results.

And we check #limitations the future holds due to the imprecise way of natural language, e.g., "give me the analytics for this week?" Did you mean "from today until last week"?

Or how data workloads need to be #deterministic and #reproducible to backfill faulty data, but AI agents aren't that.

From #ContainerDays London to Barcelona: big thanks to the #DevOps BCN #Meetup for having me!

I revisited my talk on moving beyond imperative #Docker builds toward #Declarative, #Reproducible and #Secure #OCI #Containers with #Nix:
Hermetic, network-isolated builds, clearer dependency graphs, better layer reuse across images, and a stronger supply-chain story (#SBOM + #SLSA provenance).

#ContainerDays London was great!
Thank you for the interesting talks and inspiring exchange.

I will give my talk "Beyond #Docker Builds: #Declarative, #Reproducible and #Secure #OCI #Containers with #Nix" once again next week, on February 19th at the #DevOps #Meetup in Barcelona.

DevOps BCN February 2026

In the talk “Beyond Docker Builds: Declarative, Reproducible and Secure OCI Containers with Nix” at DevOps BCN February 2026, Arik Grahl demonstrates how Nix enables fully declarative, reproducible OCI container builds, improving supply chain security, dependency management, and developer workflows.

Flathub now testing for reproducibility and the Reproducibility team helping identify software projects that will fail to build in 2038 when the UNIX Epoch will no longer fit into a signed 32-bit integer are two of several highlights in January's Reproducible Builds report at https://reproducible-builds.org/reports/2026-01/

After dithered images my next obsession is 'workflow managers' 🎈Yesterday night I binged some videos from #riffomonas about #reproducible research (CC248 to CC256). He used #snakemake , which looked very nice! Now I also looked up #nextflow It looks fierce!
I am going to learn one of them, and snakemake currently feels more approachable... But what do you think? Any advice? I want to use it in my #bioinformatics #pipeline s; I mainly write in R
#rstats #tidyverse
