🧵 Awful awful massacre in Brazil
Gente, é o maior massacre no Brasil desde o Araguaia. Entendo quem quer puxar pra Canudos ou Contestado ou etc, mas não podemos livrar a ditadura de 64 só porque ela escondia melhor seus corpos.
Morreram 41 guerrilheiros comunistas e mais de 1200 camponeses no Araguaia.

A US startup plans to deliver ‘sunlight on demand’ after dark. Can it work – and would we want it to?
Satellites beaming sunlight down to Earth sound like science fiction – and they have astronomers very worried.

When Americans watch the news and say things like "this isn't like us, we're not some third world country", I want you know that the US funded the dictatorship that took Eunice Paiva's husband. You *are* very much like this.

Acho que esse feito aqui tem que ser uma prova de que Chorão deveria ser canonizado.
Não tirando o crédito do Mineirinho, mas só de terem deixado ele tentar isso já foi um milagre e só o Chorão seria responsável por tal milagre.

Maybe it’s time for European countries to review their new “affirmative actions to help white united statean academics” since now Europeans won’t be able to take academic posts in the US anymore.
Looking to see if the new fee kills academic job opportunities in the USA. From the guidelines.
“The H-1B program applies to employers seeking to hire nonimmigrant aliens as workers in specialty occupations or as fashion models of distinguished merit and ability.”
