Building a rover is like building a race car: Spend a fortune on making everything as light as possible, and by “possible” I mean: light enough to last just long enough. If it lasts LONGER, it wasn’t lightweight enough. Because transporting mass to Mars is incredibly expensive, making things lighter is therefore the first step to saving money. And after all, the component has exceeded its planned service life by a factor of 7.
So indeed suboptimal: Still too sturdy.
#OnThisDay, 24 Mar 1944, Éliane Plewman is arrested by the Gestapo in Nazi-occupied France after six months operating as a courier for the Special Operations Executive. The British SOE supported the French resistance. A courier carried messages and equipment around their network.

Meet Fedibook!
The idea came from thinking about what it actually takes to get regular users onto the fediverse. Mastodon is great (i love it), but the follow-based model feels unfamiliar to some. Friends and Groups though — that's something everyone already understands.
So Fedibook is a fediverse platform built around exactly that, using ActivityPub. Think federated address book meets social network, with the kind of social graph people are already used to.
Current status:
- Friend requests across servers working
- News feed working, with visibility levels: public, friends-only, or local server only
Hoping to open up for early testing and feedback soon. Open source of course.
Don't know much about Pedro Sanchez (Spain) but he seems to have a habit of saying the right things in difficult situations:
"The question is not if we are on the side of the ayatollahs - nobody is. The question is whether we are in favour of peace and international legality."
"You cannot answer one illegality with another, because that is how the great catastrophes of humanity begin."
Happy #BlackHistoryMonth !
I'm still not talking about Black history. I'm still talking about white US history.
Q: Why do Black kids not do well in school? Is it because their dads are uninvolved and uncaring parents? Bill Cosby and Herschel Walker told me that, and they are good and wise men that we should listen to! It's Black dads' fault! Boo Black men!
A: No. Black kids only do poorly in school *in extremely racist countries.*

New post: Why your R package wrapper needs a sitrep() function.
One command to surface auth status, config issues, and connectivity — instead of 20 questions with frustrated users.
Real implementations from meetupr and freesurfer, plus a minimal starter template.
