@realGeorgeHotz 1. Read The C Programming Language by K&R
2. Watch everything by Andrej Karpathy on youtube
3. Write code
4. Ask ChatGPT to explain stuff to you
5. Get familiar with debugging and profiling tools
6. Use git

(do steps 3 to 6 while you do steps 1 and 2)

BREAKING: Inside Impulse Space with Tom Mueller (@lrocket) (SpaceX's 1st Employee)

FULL TOUR

The famous engineer behind the Merlin engine, now Founder, CEO & CTO of Impulse Space (@GoToImpulse)

ICYMI: Merlin still powers Falcon 9 today, the most reliable rocket engine ever flown & the highest thrust-to-weight ever developed. It's the workhorse behind nearly every SpaceX mission: Starlink launches, Dragon crew & cargo flights to the ISS, & booster landings

Tom walks us through the factory floor, from the avionics clean room to a live rocket engine firing in the vacuum chamber

Impulse is building the in-space mobility layer: the vehicles & engines that move spacecraft after launch, from LEO to GEO, the Moon, infinity & beyond

We cover:
→ Mira: precision maneuvering spacecraft & its saiph thrusters (8 thrusters, ~50 lbs thrust, 5-yr orbit life)
→ Helios: long haul same-day delivery vehicle (12 tons of LOX/methane, LEO to GEO)
→ Deneb Engine: 15,000 lbs thrust engine that powers Helios, ox-rich staged combustion, carbon skirt running over 3,000°F
→ Why 3D printing is "almost a cheat code" for rocket engines
→ In-house composite tanks, Novaloy, & copper liners machined from 700 lbs down to 25
→ 3 spacecraft in orbit + a 1,200-meter rendezvous
→ Starlink, iterating Merlin & Raptor, & working with @elonmusk
→ Nuclear propulsion, the Moon, & why compute needs to move to space

@buysidedesk @michaeljburry Financing the capex can become difficult unless revenues grow very quickly, or if global liquidity becomes scarce. That's maybe the most plausible bear case. Then there's the shortage of electricity, turbines, transformers and permitting delays for new datacenters.

[Custom Wetware @CustomWetware]

@buysidedesk @michaeljburry Demand is tied to how capable the models are. They keep getting more capable every year. It's hard to predict how quickly it will happen, but I think capabilities will grow fast enough to keep demand higher than supply for a decade or more.

@healthspanmed All those words and not a single mention of the fact that studies showing a low limit all use whey protein which is quickly digested, and studies showing higher limits use other forms of protein that are slowly digested such as casein.

Most people might miss the biggest benefit of sauna

You need to get really really hot…

Your core body temperature needs to hit 102.4°F (39°C).

For reference, a fever is anything above 100.4°F (38°C)

So I swallowed a temperature monitoring pill. It goes through your digestive tract and precisely measures your internal temperature every 30 seconds.

When your core body temperature hits the goal of 102°F, your body releases these proteins (heat shock proteins - HSPs) that clean up your body’s debris.

I was curious what time my body hits this goal because up until now, I’ve been doing 20 mins of 200°F dry sauna.

… it turns out it takes 31 minutes

It feels like you’re dying.

I didn't expert such pain and panic.

Before this experiment, I did over 200 sauna sessions at 200°F for 20 min.

This means I likely never achieved the heat shock protein (HSP) threshold at 102.4°F (39°C), which deprived me of so much sauna-health goodness.

If your sauna doesn’t heat up to temperatures allowing your core temperature to reach 102.4°F (39°C) or you struggle to tolerate heat, do not be discouraged. The dry sessions I did at 200°F (93°C) for 20 min still showed incredibly health benefits.

My previous 20 min sessions still showed:

1) 10+ yr reduction of my vascular age

2) 87% reduction of microplastics

3) detox of environmental toxins

4) fertility marker improvement

Will report back once I have results on this new protocol…

@hkepcmedia Authentic experience of buying a Nvidia GPU

@SchmidhuberAI Assuming 100t downmass per Starship mission (probably wrong but let's use it as an illustration), it would take 2160 Starship missions to bring that much gold from space back to Earth. Not including the equipment and fuel to move the gold from an asteroid to Earth orbit.

@Autonomous_Chad @MartinShkreli The end date is July 1, not June 1.

[Custom Wetware @CustomWetware]

@championSpeed12 @MartinShkreli But the end date is July 1, not June 1.

[Custom Wetware @CustomWetware]

@Autonomous_Chad @MartinShkreli The rules weren't even followed in this case, the market just resolved to the wrong result presumably because that was profitable for whoever was in charge of the decision

Another reminder that prediction markets are scams

[willo2 @willo2_Poly]

I was just scammed for $500K by Polymarket.

I am "willo2", the top holder of YES on "MicroStrategy sells Bitcoin by May 31st".

Here's what happened:

[Custom Wetware @CustomWetware]

@MarketMatrixs Actually, it rallied because they announced a return to flight and then dumped because they announced a capital raise to service debt

[Custom Wetware @CustomWetware]

@andrew_n_carr No, it means they are only able to get 20% of the theoretical FLOPS out of the GPUs when they use them
