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.

@luc0x61 @fesshole I think the main point was the fact that both persons knew these nerdy facts about their phone numbers? Not the facts themselves.

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.

@jimbob Looks like it's from 1982, but is actually at least 1500 years old!
@CartyBoston fun fact: A table in the (locally) famous Oslo restaurant Theatercafeen is nicknamed Kharg Island, because it is the preferred table of John Fredriksen who made a fortune when he (as one of very few) shipped oil from Kharg during the Iran-Iraq war in the 1980s.

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."

@lwpembleton Brent Cobb is a guy I really like. He made an album in 2025, but I haven't really listened to more than a couple of songs of it.

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.*
