Human being, being human. Trying, not always successfully, to leave the world a slightly better place than I found it. It's a modest goal, I know.

Anti fascist. If you’re not, what are you?

Profile header is a slice of a pencil sketch drawn by my brother, an architect. The crop focuses on my eyes, and the craggy lines radiating from their corners. My eyebrows appear to have gone feral.

Profile image is me as an almost 40 years younger man. I have dyed black crimped hair in a broad mohawk.

"The recent study focuses on the amount of lithium left behind from a single rocket reentry. Previous studies have already shown that lithium, aluminum, copper, and lead left behind from the reentry of spacecraft already exceeds the cosmic dust influx of those metals to the atmosphere.

It’s not clear yet how exactly this change in the atmospheric chemistry would affect life on Earth, but the researchers behind the new study believe that there is enough reason for concern. Still, more research is needed to narrow down the impact on our planet.

“There are many elements present inside spacecraft which are not very present in our atmosphere due to natural causes,” Wing said. “We know very little about what metals actually exist in the atmosphere and how that relates to re-entry pollution.”"

Or, more probably, not.

Just publish you fuckers.

Reading Yegge’s rant and the much shorter and more polished siddhantkhare.com/writing/ai-f (“AI fatigue is real and nobody talks about it”), I keep coming back to this, which I published in 2020 and is sort of at the center of my thinking about everything: tbray.org/ongoing/When/202x/20 (“Just too efficient”)

"As two professors of energy studies – one British, the other Swedish – we have long puzzled over the stark contrast in how winter is experienced inside our homes in the north of England (Sheffield) and southern Sweden (Lund)."

Not sure about the death bit, but I'm prepared to be lightly injured.

Perhaps the fact that there is no reliable data about this is, in itself, revealing.

Why not just publish the data?

There is an art, it says, or rather, a knack to flying. The knack lies in learning how to throw yourself at the ground and miss. ... Clearly, it is this second part, the missing, which presents the difficulties.

"Vibe coding" is a bit like watching a 5 minute YouTube video about dentistry, then extracting half your own teeth.

Both are going to end in a world of pain, with you paying someone who *actually knows what they're doing* to fix the mess.

And paying ten times more than you would have done if you'd just got them to do it in the first place.

Here's some GREAT news: the first kākāpō chick in four years hatched on Valentine's Day! Kākāpō are nocturnal, flightless parrots that are endemic to New Zealand and are critically endangered. Only 236 adult kākāpō are alive today, so every chick is a milestone for the species!

Edit: Thanks for all the support, everyone! I’m good to go for now.

I’m looking for some help in moving my Etsy shop over to a Wordpress/WooCommerce site that I fully own and manage.

I would like to hire a developer to help me along the way, as a consultant.

If you — or someone you know and trust — would be interested, please send me a DM. I’m in Canada 🇨🇦

If you’d like to see what I’m going to be working on, my Etsy shop is at brittbuilds3d.etsy.com

Thank you! Boosts appreciated! :boost_ok:

Aside from those who are posting this shit to undermine labour, I get that it might feel empowering to generate code, because we've gatekept and mystified the fuck out of it.. but for me as someone who's spent many years now teaching folk coding skills, what I want people to understand more than anything is *it's just code*

It's not magical or special, it's just a means to an end, it can be taught, and learned

New post, and this one's definitely one of my weirder ones: it's about how most of the tech industry shows symptoms of something that looks like gender dysphoria.
