Mike Mahoney @mikemahoney218.com · 7hEven if you ignore the eugenics-y degrowthers (and what an “if”!) it’s absolutely not clear what mechanism they want to decide what consumption is valid and what isn’t If it’s a price mechanism, well, we’re sort of back to the eugenics-y degrowthers! 130
Mike Mahoney @mikemahoney218.com · 7hThe degrowthers would tell you the incentive is that we live on a finite planet and to maximize long-term outcomes we need to reduce consumption and population, and they think that should be enough justification (just, don’t ask who exactly they want to stop having kids) 130
Mike Mahoney @mikemahoney218.com · 7hDegrowth in general starts from a place of “if everyone agreed entirely with me and changed all of their behaviors” and that’s just never seemed like a winning strategy to me — and in all honesty I think the prevalence of degrowthers in climate communication has made us less successful 140
Mike Mahoney @mikemahoney218.com · 7hGreat thread. This is a problem with a lot of climate journalism (especially at outlets like The Guardian) — they assume that energy usage would be stable or decreasing without green build-out, when there’s no clear reason that would be true!! 141

The permitting bill would enact the mandatory rules that Democrats say they want. The policy that Schumer is calling for in the screenshot — that data centers must pay for all of their grid upgrades — is what’s required by the new bill. 2267

Mike Mahoney @mikemahoney218.com · 20/08/2026Agree 100% with this — the expectation for students to take long-term volunteer positions is morally wrong & locks out underrepresented communities. It’s also not even a great way to get your foot in the door! Unpaid staff are not first in line for cool experiences or facetime with researchers. 131

Mike Mahoney @mikemahoney218.com · 28/07/2026I don't blame folks for not deeply investigating the implementations of their software -- this is why packages exist after all -- but periodically I get bug reports that X doesn't match Y package and: yes! on purpose! that's the reason X is there at all 😂 381
Mike Mahoney @mikemahoney218.com · 28/07/2026"people just assume languages and packages will all agree" This is absolutely true, which is also annoying as a package author -- a lot of my software does something similar to other packages, but makes different choices, because I think they're better!

Mike Mahoney @mikemahoney218.com · 17/07/2026As the world warms, precipitation across a lot of North America is becoming "flashier" which means it can't enter the soil as well. That's meant more drought, which makes fires dramatically worse than in the past. Pretty accessible explanation here: theconversation.com/the-us-is-se...theconversation.comThe US is seeing stronger storms, so why are droughts getting worse?Even though annual precipitation is rising nationally, the landscape is drying out more rapidly. That’s changing the water cycle. 111
