- New preprint online today - spearheaded by my very talented postdoc, Jonas - on a new reusable, open-source software implementation of the second-order trust region algorithm: arxiv.org/abs/2509.13931 Here are some of the reasons why this library may be useful for a great many in our community. 👇
- New v2.0.0 of OpenTrustRegion now released. Please see the changelog for an account of all of the major changes: github.com/eriksen-lab/...
- Code: github.com/eriksen-lab/... On my end, thanks to @villumfonden.bsky.social & Independent Research Fund Denmark for generous funding.

- The OpenTrustRegion library is designed with an intention to be more versatile, more robust, and more reusable than any previously reported implementation of the second-order trust region method for general electronic-structure calculations.

- This was Køge, Denmark in November 2021. There were like at most a few hundreds of us in the stands and it was absolutely freezing. Good times were had by all, but those were hard times. Today, Arsenal Women are champions of Europe. 🥳

- While intentions are arguably good, this is unfortunately as empty an invitation as you'd ever see from the Danish Chamber of Commerce. In Denmark, we simply don't have the institutional capacity nor the necessary funding infrastructure to accommodate such an exodus. Massive changes are needed.

- Reposted by Janus Juul EriksenIt's ridiculous, but there hasn't existed a one-liner to quickly get functional groups of a molecule. Little Friday night coding exercise to get this working. Enjoy - and let me know of any missing functional groups! I could only do a few hundred.
