The idea that by "making a deal" with the Pedo Liar In Chief of the United States we can avoid him using the power of his position against us is ludicrous. Nobody believes this. The only people calling for a deal are willing traitors.

ICYMI: This story is getting lots of hits on our site today. It argues that @markcarney.bsky.social should avoid any attempt to appease Donald Trump since the U.S. president reneges on any deals he makes: theconversation.com/donald-trump...

#AI #LLM Something I've not seen commented on is the explosion of bot-impeding pages (e.g., via Cloudflare) that now appear before web pages load. The cumulative time waste for human users has got to be in the billions of person-hours. An immense burden imposed on everyone by the AI-bro assholes.

I expect ~30 TW by 2036, because I understand exponential growth. And yes, the number seems absurd, because our imagination sucks. But the fit to the admittedly sparse data is good, and while I'm not confident of the precise value, I am very confident it will be much higher than 9 TW.

Don't look now, but the world has now installed 3TW of solar. Took 10 years to get from 100GW to 1TW. Less than 3 years to get to 2TW. Less than 2 years to get to 3TW. Analysts expect *9TW* by 2036.

I guess while everyone is airing their pandemic grievances I’ll add that as a nurse, the most traumatic thing about the pandemic for me was the lack of appropriate PPE and the denial of airborne spread that STILL happens in healthcare

This is a bad move. We should be investing in molten salt reactors designed in Canada. SMRs are the last gasp of water-cooled nuclear, which is a dead end. Molten salt is the future. We could be a leader on this, like so much else, but choose the wrong path.

Canada’s Nuclear Strategy Depends On Foreign Reactors and Foreign Fuel Canada is betting heavily on small modular reactors. Prof Mark Winfield explains why that may create new dependence on foreign reactor designs/enriched uranium fuel. @YorkUniversity youtu.be/F4gpARbRetg

Unless there's some real just-so stuff going on this would allow the construction of a Maxwell's Demon, which can't exist (because it would require creating information out of nothing). So probably not "heat", but infra-red radiation, which are *not* equivalent (IR can have any angular distribution)

It's an artefact of an institutional medical culture where 2+2 can be 5 if the right people say it is. Train people to believe that, and it's not just their answer to that one question that you can't trust - you've destroyed their capacity to understand objective reality as distinct from opinion.

In a word: misinformation. Anti-vax misinfo is called out, so we can all point and laugh at a stereotyped "ignorant redneck" whose kid just died of measles for a lie. Aerosol misinformation isn't, as it's spread by the same medical management class that protected Wakefield's lie for over a decade.

there are definitely downsides to the nuclear block but the reason I keep coming back to it as necessary and good is that it completely ruined the whole MAGA engagement model to the point that they prefer to mock us from the nazi bar rather than come here to troll us directly

Bluesky oldheads will remember that brief period of time when the conservative trolls tried to storm the place and were flummoxed by the idea they would have to organically grow an audience and that someone who didn't want to talk to them could nuke every interaction they ever had from orbit

Clean indoor air is helpful against disease all the time, not just episodicly "in a pandemic". We treat drinking water *all the time*, not just during cholera outbreaks. Until we get over this medical/reactive mindset, airborne pandemics will continue. Put engineers in charge of public health!

2. Clean indoor air: helpful in a pandemic and good for health and learning at all times (and not just in schools but other buildings too) 3. Effective public health measures: testing, contact tracing, support for isolation, communication, etc 10/12
