I struggled to find any guides for how to do this so I've written a blog post about how to use published results from global glacial isostatic adjustment models to derive time-series for sea-level change for any specific location (with Python or R): https://iroalkvam.com/posts/02gia_models/index.html

For people familiar with the topic this is likely basic stuff, and for others it might be a bit narrow, but it was a useful exercise.

Yesterday I updated the roadmap for open-archaeo, which is a list of open source archaeological software and resources (https://open-archaeo.info). while it's fairly comprehensive, it could really benefit from a focused attempt by people who specialize in specific sub-disciplines to identify the software in their domains of expertise. If you'd like to contribute in this way, please check out the roadmap and/or get in touch!

#DigiArchMaintainathon

Ideally I would have time to spare to look into optimizing part of the code for my R package shoredate (https://github.com/isakro/shoredate) for this weeks #DigiArchMaintainathon Will have to see about that. For now I'm pleased to finally have dealt with some weird testing issues that have been causing my R CMD checks to fail for a while. Comes with a dopamine reward:

👾🏺 This week we are hosting a week-long #DigitalArchaeology #maintainathon, an opportunity to clean, document and revise older code together!

If you’re a #ComputationalArchaeology *st take this time to update your README, add code comments, write a unit tests or consolidate your project roadmap, and post about it using #DigiArchMaintainathon. We’ll boost these posts to extend best practices throughout our wonderful #OpenScience research community!

Personal computing

When computers entered the homes it was often as toys or toy-like artifacts: These machines, usually called "home computers", were often used like gaming consoles with magazines giving you code to type in to have simple games on them. Their use was limited to people who wanted to play arcade games without losing all your money or people who just loved technology. After a while and through some marketing the term personal computer was established and describes the machines people have at home […]

We really ♥️ this piece from John Hawks on humans looking at the stars, especially how he picks up African #huntergatherer cosmologies on the link of the #Moon to #Menstruation 🩸

Right now I'm involved in one of the MOST important papers of my life with Hadza hunter-gatherer experts on Hadza beliefs and practice around menstruation, hunting and the moon.

The key here is no one understands Hadza #Epeme--their moon-scheduled ritual for healing and good hunting--unless they also understand menstrual beliefs and practice.

When did our ancestors start looking up to the stars?

Changes in the sky have been important to peoples throughout the world. That connection may go back much further than our species.

XRONOS is an open data infrastructure for the backbone of the archaeological record – chronology.

As described in our paper out today in the Journal of Computer Applications in Archaeology (https://journal.caa-international.org/articles/10.5334/jcaa.191), XRONOS is the most comprehensive chronological database yet published, with over 350,000 radiocarbon and 75,000 site records.

It is also the first global database to support other types of dating, such as by tree-rings or typology.
