@dazinism @mathiasx @cstanhope @requiem I grew up on an international community and spent 15 years of my early life there. and I have spent time at a ton of different communities in the US. I think the idea of "failure" is almost always misguided. Everything has a certain entropy and if we dont take that natural entropy into account when we are designing systems those systems will be naturally decay. The concept of the TAZ here I think is actually really important to consider early on.

It has become clear that the software world is basing fitness to hire too much on specific technology specialization.

Is it due to ageism? i.e., the fact that popular technologies change every 10 years (guess not data). e.g., I have written make files, but haven't touched ninja or even a tool like meson.

Is it productivity concerns? i.e., eliminate training time.

I would expect critical thinking to be a much higher bar to entry than technology.

🕵️ Intrusive surveillance technology is increasingly used during protests around the world and has a chilling effect on freedom of assembly.

Hey @SocialCoop braintrust, anybody know any #coop developers in Kentucky?

My wife was looking at the properties of #ellipses such as the one where the sum of the distance of all points on the #ellipse from the two foci are the same and how that relates to the standard equation of an ellipse. I wrote these notes up neatly using #LaTeX to explain the relationship.

To put it up here, I converted the #PostScript pages to #PNG format using #GNU #Gimp and the figure was produced using #Tgif.

Some impressive green-washing post from @EU_Commission here:
social.network.europa.eu/@EU_C

Extremely concerning to see how an official body can promote things that go so obviously in the wrong direction on most indicators.

Would be good if scientists reacted here and on Twitter.

Opinion: Davos Was a Case Study in How Not to Talk About Climate Change
In emphasizing technological solutions, the elite are sidestepping their own responsibility for the climate crisis. - Jag Bhalla @ Undark: undark.org/2022/06/30/davos-wa
