Os cara caindo na armadilha do Estadão, se abraçando no STF “pq se a mídia malvada diz X, eu quero Y” e eu que tenho 5 anos. Ai a gente vai perder a eleição pq compramos um escândalo que não é nosso so pra “ir contra a mídia malvada”. Boa estratégia! Vai dar bem certo!

Mais um escândalo pra “esquerda” pelega se abraçar ao sistema falido e provar que queremos ser pra sempre zeladores do neoliberalismo. Coisa linda de se ver! Vamo sim nos abraçar ao STF e nos afudaremos juntos pra depois choramingar que perdemos a eleição pq todos são malvados. Baita ideia!

Nothing to see here, just YouTube casually trying to sell Nazi cosplay hats… And don’t worry, it knows pretty well that my political views are on the other side of the spectrum. It’s just really focused on trying to change that at any cost. I don’t do target practice.

If we taxed 1% more on the top 1%, we could fund hundreds of thousands of these and still have enough money to save UK academia from collapsing. (1% on the 1% could be around £13.4B a year…)

Not even the tories were this incompetent and dumb. It feels like Labour is doing everything they can to elect Farrage as quick as possible. Stop being the janitors of this failed system and do some good and change for once.

I am honestly getting sick and tired of cosmology as a field. It's a race to the bottom, papers appearing everything with fundamental methodological mistakes that will be accepted anyway because they ~feel right. Science done on vibes and not with criteria.

Excited to share something we've been building at the Oskar Klein Centre! A few months ago, an #NVIDIA #DGXSpark landed on my desk. I started running local #LLMs, not for chat, but to see what they could do for science... and so we started building a multi-agent system for cosmological analysis!

The latest budget proposal announced by the largest UK science funding agency threatens to severely affect UK astrophysics research. My colleagues and I are fighting back.

One reason why UK universities are in trouble is growth of layers of management, HR & marketing These depts do not bring in money. They consume but don't produce Worse still, many of them like HR create massive additional problems & costs -- all distracting from core mission of research & teaching

Science and Universities are under attack in the Global North regardless of political alignment of the current government. It’s not a crisis caused by the far right, it’s crisis caused by maintaining neoliberal ideology Under neoliberalism, it makes zero sense to have public research and education

this narrative the media have decided on is so fucking insulting. there's no difference, politically, between any of these prime ministers. that's the problem. not the voters. it's that our system is fundamentally broken and the press won't let us pick a non-neoliberal.

I think sometimes the UK should learn from how we do things in Latin America: Before things would reach this stage, students and staff would have occupied the chancellor’s/provost’s office, barricade the doors to the university and demand changes that would avoid these massive layoffs.

STFC cuts will accelerate the closure of UK physics departments, even though everyone recognises the importance & value of physics to UK PLC. Physics is explicitly listed as an area affected by planned compulsory redundancies at Nottingham. So sad to see this. www.theguardian.com/education/20...

Thousands of University of Nottingham staff told they are at risk of redundancy
Institution says it could run out of money by 2031 and wants to cut more than 600 academic and support posts

Here’s an idea: when dealing with call centres or business chats so they can fix something messed up, always end the conversation with a little pep talk on starting a union with whoever you are talking with. That’s the best way of getting back at these tech giants: unionise their workers
