Exciting update! You can run Image Based Meta-Analyses (IBMA) on our platform 🚀 We've known for ~TWO decades that images are better than coordinates, but data has never been shared/organized properly to make that an accessible reality. We did it, enjoy: compose.neurosynth.org

OSS burnout claims another project. On 2 Apr, an entitled user angrily asked the burned-out maintainer of nvim-treesitter to “go switch to something that doesn't require interacting with people”. The maintainer replied “OK” — and archived the repo, stopping development of nvim-treesitter.

Yes, the GOP controls Congress. That's why it's key to show Congress COULD stop the madness. And it's not just the DHS bill. Congress could repeal the prior multi-year $75b for DHS; set up a special investigative committee (cf. Watergate); amend the Insurrection Act; etc.

A week ago we had an incident where there was a school bus with the STOP sign open and kids were getting on the bus and it was surrounded by ICE agents. And this is 7:20 in the morning and — just — you get that fight-or-flight response.” At first her 9-year-old was carrying her passport in her backpack; now it’s in her back pocket. “I have to prepare them for it if they get stopped,” she says. “I said, Do not engage. This is not the time to be cussing at anyone. But she said, Mom, if I create enough noise, my friends can get away.”
