@jespr @collin_jilbert Just don't leave it somewhere and forget it
@Grace_Alfar Likewise Grace! Hope to see you around Austin or maybe on the "Rails"
@jespr Mine would end up just like this... Lonely water bottle left behind for someone else to wonder about
This is the number one reason I don't carry around a water bottle.
@_williamkennedy Thats a shame man but hope to catch you soon
@_williamkennedy Lets see how Austin treats us!
Also... a missing pieces of the compliance and security story for agents!
Could Jev be the iPhone moment for agents? Not because it is a smarter LLM. It isn’t even an LLM. @typesafeai's Jev is a decision model: give it context and a set of questions, and it returns structured choices, probabilities and confidence scores in milliseconds. That makes it
@dhh Fixed my home lab by adding another 5090 to the stack!
When will we rebrand RailsWorld to AmandaWorld because really we know she's the real reason the show happens!
@dhh Oh, just about a million small fires popping up around #RailsWorld, no biggie.
On my way to Austin! See you all soon...
@_williamkennedy This. My friendship doesn't come with the condition that we agree on everything, or even important things.
@GregMolnar Hope to see you at the RailsWorld! Im sorry you had to deal with that, and I definitely understand what that is like, unfortunately.
Irina is the hero we needed 💪
Last night I was thinking about this: new Rails apps not classified as Ruby (but HTML). Crafted a tiny PR to Rails, and this morning it was already merged 😱⚡️🥳💫
