@boardyai building first-gen hardware prototypes for complex systems at Sidecar Lab so teams don't bet on the wrong design. want in on Boardy Pro

Turn your volume up! 🚀 We are Stoke Space. From seed money to engine testing, we’ve moved faster than any rocket company in history. We’re building the holy grail of rocketry: a fully and rapidly reusable rocket.

Grab some marshmallows!

[Stoke Space @stoke_space]

WE JUST LIT THE ENGINE! Both pumps up to power and all chambers nominal -- Full celebration! 🔥🚀

[Stoke Space @stoke_space]

15 chambers, 1 set of pumps, first fire. We’ll be spending the next few weeks ramping up power.🔥

I probably should have mentioned it, but I work here leading avionics.

[Stoke Space @stoke_space]

Yeah, this rocket engine looks different. That’s because it is! You’re looking at our SECOND stage engine, which was designed from the ground up to be 100% reusable and have screamin’ high performance. Time to put it through its paces! 🔥🔥

@andrewbostom I did. But the sources I peeked at don't list outcomes, just # of tests and +cases. Outcomes (hospitalizations, deaths) are not listed. So you're just going to assume that there were no hospitalizations or deaths? That's not a particularly rigorous study...

[Kosta Grammatis @kgram]

2.13% of USA's population has been infected with COVID19.

[Kosta Grammatis @kgram]

@andrewbostom I see case information but no mention of outcomes. Where are the outcomes listed?

[Kosta Grammatis @kgram]

The US is 4.9% of the way complete towards having 1% of the country infected with Coronavirus.

@PairwisePL Weird place to reach, but worth a shot: I live across the street from you and it sounds like a bearing is going out on one of your AC units / exhaust fans. Very loud intermittently. Could be bad for your work if went out while you're not in the office. Heads up!

@OGBTC @EliNBCBoston @PerryNBCBoston @NBC10Boston @MGHMedicine @NECN @GlobalHealthMGH @gustojunk @COVID19Tracking @coronaviruscare Just tore into my AC to get at one - that is def. the solution. https://t.co/ZWvYPetISX

@PerryNBCBoston @NBC10Boston Please don't promote this, it's not a mask. It still needs a filter, and the filter material is what's in short supply. Read this: https://t.co/TMRQLw2Mu9

@EliNBCBoston @PerryNBCBoston @NBC10Boston @MGHMedicine @OGBTC @NECN @GlobalHealthMGH @gustojunk @COVID19Tracking @coronaviruscare Please don't promote this mask. Even if it worked it needs a filter, and the filter material is what's in short supply. Read this: https://t.co/TMRQLvLbCB

@sammyfowles @PerryNBCBoston @VPace @NBC10Boston That's no mask. It is the shape of a mask, but it is peppered with ingress points for air. N95 masks filter up to 0.3 μm (0.0003 mm) - because viruses are that small. The material that would act of the filter ('melt blown fabric') is what's in short supply. No filter, no mask.

@nxtbgthng The first thing I tried was the region setting :( I am using iOS 9, so that’s probably the issue. Do you need photos / logs from me? Happy to help :)

[Kosta Grammatis @kgram]

@DanielBogdanoff have fun :)
