Hands-on GitHub Actions (Getting Started with GitHub Actions Workflows)

The InvenioRDM GitHub Archiver (IGA) is a new software tool created by the Caltech Library. InvenioRDM is the basis for many institutional repositories, such as CaltechDATA, that enable users to preserve software and data sets in a long-term archive. The metadata contained in the record of a deposit is critical to making the record widely discoverable by other people.

I'm teaching a class on quantitative methods in linguistics, and after getting tired, over the years, of debugging everyone's computer before we could get to the content of learning R (much less quantitative methods), I decided to seize control. I'm running the course through GitHub Classroom which comes with an educational allowance for using GitHub codespaces.

Let $M^{r}$ be a connected orientable manifold with the Euler characteristic $χ(M)\not \equiv 0\operatorname{mod}6$. Denote by $\mathrm{SAut}(F_{n})$ the unique subgroup of index two in the automorphism group of a free group. Then any group action of $\mathrm{SAut}(F_{n})$ (and thus the special linear group $\mathrm{SL}_{n}(\mathbb{Z})$) $(n\geq r+2$) on $M^{r}$ by homeomorphisms is trivial. This confirms a conjecture related to Zimmer's program for these manifolds.

Playing with my eLife Lens-inspired article viewer and some recent articles from ZooKeys I regularly come across articles that are incorrectly marked up. As a quick reminder, my viewer takes the DOI for a ZooKeys article (just append it to http://bionames.org/labs/zookeys-viewer/?doi=, e.g. http://bionames.org/labs/zookeys-viewer/?doi=10.3897/zookeys.316.5132), fetches the corresponding XML and displays the article.Taking the article
