Pinned toot

Just realized I never did an on Fediscience...
So hi there! (better late than never)
I'm a physicist by training doing a postdoc on and

I like books, and I'm generally interested in and
I mostly talk about my research fields here, if you want to hear about FLOSS, (in) and , check my alt: @tfardet

I was looking for a tool in to do ...
I did not find anything I really liked, but stumbled on an old git repo with promising PRs: github.com/fengwangPhysics/mat

A day later, I have a good enough tool for my use cases: github.com/Silmathoron/mpl_cho

If you want to check it out or hunt bugs, it's now on Pypi: pip install mpl-chord-diagram

Conference 2020 is online (unsurprisingly) and organizers asked poster presenters to make a trailer video...

This was surprisingly difficult... I've been at it for hours and I'm only sending this because I finally decided that it was not worth spending so much time on it, but I'm still unhappy 😩
I can only imagine how time consuming it must be for people making regular videos!

Anyway, I'll be making some advertising for in the process ;)

Oh, sci-hub.tw is down. So now we have to explain everyone that they should NOT use sci-hub.se under any circumstances.

Mutual mentorship/support/"Academics Anonymous" 

Building off the energy and community from #SummerSchool, scholar.social will be hosting a mutual mentorship and support programme

The goal: to provide a venue for mutual support for people who are in academia, adjacent to it, considering entering it, or who have left it

Due to the nature of the programme, it will be intentionally a small group by invitation only, where everyone knows everyone

DM @Cyborgneticz or @bgcarlisle for more details

Researchers have found iron oxide (i.e. rust) on the moon! This is using data from the Indian space agency's Chandrayaan-1 probe in 2008.

Rust is very surprising, because it should require oxygen to form! The theory is that once a month, the moon passes through the tail of Earth's magnetosphere, and trace amounts of oxygen ions are carried there by the magnetic field.

my coworker's husband contributed to this research!

It turns out that what I probably need to do is a systematic quantitative literature review.

My brother (a PhD candidate) fortuitously shared this with me, and I think it's a start.

Fooled for several days by a 100% CPU utilization and frustrated over a performance drop with Janusgraph passing about 100k nodes and 100k edges. It dropped to nearly zero.

I was about to go full metal and buy a 6 node mATX cluster with 48 AMD-cores and 96GB of memory.

However, double-checking my config I noticed that it had reverted from being Cassandra and Elasticsearch-backed to an in-memory config. We all know how that goes with a standard Java configuration.

I guess my 2014 Mac mini will get to live a little longer.

Playing with magnets and hall effect sensors. We will attach a magnet to one side of the clam's shell and the sensor to the other end! Then we use an arduino to log the voltage coming off the sensor to relate to how open or closed the clam is! This process is called valvometry and will allow us to detect the changes through time of when the clams are open and collecting sunlight for food. I'd never tried an arduino before but it is fun to play around with!

A friend sent this article to me and I'm not sure what to make of it... I do agree with some of the analysis, but wonder how we can make scientific publication work in a world where generalized competition and evaluation by H-index is the norm...

This year's IgNobel Prize has this very apt prize for #COVID19 . It's awarded to the leaders of the US, UK, India, etc. "for using the COVID-19 viral pandemic to teach the world that politicians can have a more immediate effect on life and death than scientists and doctors can."

Is anybody here into electron microscopes? (of any kind)

Some planetary nebula contain linear features within the nebula called filaments. We're not sure why these form. (Hubble image of PN IC 418)

Does anyone here use WriteFreely (writefreely.org/)? What do you think of it?

It is very important to say 'I don't know' and to practice not knowing. Academia demands that we be experts, and if we stumble at all then we are punished for it. We are not allowed to have partial knowledge or ongoing knowledge.
But that's toxic. It's okay and good to not know things - even things in your own field.
The beauty of it all is that we will never fully know anything. We can only ever learn more.
