I’ve been working on applying strict static typing to my Python package class-resolver and ran into an interesting way of using generics in combination with parameter specification variables (i.e., ParamSpecs). Normally, if you want to type annotate a function, you use the Callable, which works like the following: from collections.abc import Callable #: the [int] represents a function that takes in a single integer, #: and returns a single

This notebook is the result of a collaboration between myself, Dr. Jeremy E. Monat, and Dr. Phyo Phyo Zin. This is a hands-on tutorial that guides readers through implementing skeletal editing transformations using Python and RDKit, and Phyo Phyo focuses on the high-level principles and applications in the blog post How to Use Skeletal Editing in Drug Discovery: Key Benefits & Applications.

In April, two members of our research group were featured in interviews: Dorothea Strecker, who has been studying shadow libraries for many years, was interviewed by the Norwegian newspaper Klassekampen (Stormyren Larsen and Ugelstad Aas 2025). The interview was prompted by the investigation “The Unbelievable Scale of AI’s Pirated-Books Problem” published in The Atlantic (Reisner 2025). Heinz Pampel was interviewed for the @mediasres program

Funded by the Federal Ministry of Education and Research (BMBF), our research project Pro OAR DE investigates current challenges in operating institutional repositories (IR) in Germany. Since completing our initial research phase—which included a systematic review and an interview study with IR managers at academic institutions—we have organized four networking forums since November 2024.

The commonmeta Go library has seen a major update this week that dramatically simplifies working with the Research Organization Registry (ROR) data dump, including conversion to other serialization formats (e.g. JSON Lines) and metadata formats (InvenioRDM), and integrated affiliation matching.

Puzzles to solve, but how? It keeps occupying my mind. This has to do with finding the right mix of the public values that are connected to justice, humanity and autonomy, and the “neutral” position of the library (or not?). I have now attended three of the six afternoons that form part of the SURF Course on Digital Sovereignty (for Executives in the field of education & research). And would like to make up my mind as a mid-term activity.

It operates on a vdir directory of .ics files as managed by tools like vdirsyncer, which allows it to interact with CalDAV servers. The command-line has the list, search, show, add, delete, and edit subcommands, and has full timezone support.

Eon is an Effects-based OCaml Nameserver using MirageOS’s functionally pure Domain Name System (DNS) library with direct-style IO (as opposed to monadic IO) using OCaml 5’s effect handlers [1] created as the basis to implement some of ideas from the Spatial Name System.

This site is running in 11ty and is built locally, after which the live site (which gets built into the _site folder) is pushed to my Reclaim Hosting account, where it's served up as kfitz.info. As an intermediate step, I have been pushing the code and content that builds the site to a GitHub repository, and then the _site folder to another GitHub repository, kfitz-site, mostly for preservation/backup purposes;
