So I moved to a different position and now my old employer #UtrechtUniversity has a wonderful #AssistantProfessor position in the ODISSEI Social Data Science team. It's a really nice environment with interesting, diverse, and impactful research and teaching!

Just updated my small :python: package polarsgrid for tidyverse-style expand_grid functionality in python polars 🐻‍❄️

https://pypi.org/project/polarsgrid/

Version 0.4.0 has unit tests, more efficient row-index computation, better CI.

Major new user-facing improvement is that you can now enter any iterable as the input, not just lists. So create your grid with range(10) instead of list(range(10)).

See this preprint for use-case

#python #polars #rstats

We've created a way to display interactive maps in the browser, completely client-side! #gis #gischat

Drop your data in as #csv or #apache #parquet file, and your vector shapefile as a #geojson, and your map is ready to go!

It's hosted on #GitHub pages (so it's free!) but can be embedded anywhere

(we tried out @penpot in the design process!)

More information and the full grant proposal here: https://tdcc-synthetic-data.nl

NB: ideally we are looking for someone already employed at #SURF, #UtrechtUniversity, #MaastrichtUniversity, or #DANS #KNAW in NL, but please still apply if you are not part of these, we will arrange a secondment agreement.

#jobalert do you want to contribute to responsible use of #SyntheticData in science and beyond?

We have a position available as part of our newly started project on implementing #SyntheticData in the real world.

It is a part-time job, we're a nice consortium, and we are very excited to work on this project!

If this resonates with you, please apply! Even if you feel like you are not the perfect match, we are very flexible.

I was annoyed that there is no "expand_grid()" function in :python: #Python as in :rstats: #RStats #tidyverse

So I just published a small package on #PyPI !

Introducing polarsgrid
https://pypi.org/project/polarsgrid/

Using the excellent #polars 🐻‍❄️ package, easily create a table with product of factors:

from polarsgrid import expand_grid
expand_grid(a=[1, 2, 3], b=["x", "y"])

Yields all combinations of its inputs as a #DataFrame

It can also produce a #LazyFrame for streaming extra-big tables to disk
