“@engineers_feed Voxel size of the simulation”

“@engineers_feed Arguably, the practical limit of pi is the number of digits required to measure radius of the universe in units of Planck length https://t.co/4R8wIL0FzS https://simple.m.wikipedia.org/wiki/Planck_length”

“Just leaving the engine bay of Starship https://t.co/JTnFfNaymh”

“@engineers_feed Ok, maybe a little pontificating”

“@engineers_feed Nuclear is way safer than coal”

“@jxeral Ironically, the company that made the first commercially viable internal combustion engine car saved the company that made the first commercially viable electric car!”

“@engineers_feed Lol no, Newton’s Third Law”

“@breeadail And engineering”

“@engineers_feed Especially the last one”

“@Jason @DavidSacks Most engineers don’t feel strongly about politics, but do want to work with other great engineers. Silicon Valley has world’s best engineering talent, but is co-located with San Francisco, which is far left. Thus, far left gained control of an incredibly powerful info weapon.”

“@rookisaacman @engineers_feed X Æ A-12 Musk”

“@engineers_feed Neil A, which is alien spelled backwards, was first person on the moon, and the year was 69 …”

“@engineers_feed @Twitter So much to fix at Twitter (sigh)”

“@KimDotcom Twitter engineering is working on it”

“@NASASpaceflight Full test duration of 14 engines”

“@sampullara I was told ~1200 RPCs independently by several engineers at Twitter, which matches # of microservices. The ex-employee is wrong. Same app in US takes ~2 secs to refresh (too long), but ~20 secs in India, due to bad batching/verbose comms. Actually useful data transferred is low.”

“@engineers_feed Output of any company is the vector sum of people within it. Someone may be a strong vector, but negatively affect those around them to such a degree that they are a net negative.”

“@alex_avoigt I still do a lot of work at Tesla! Was at our Palo Alto engineering office until late Thursday night when I had to redeye to NY.”

“@nichegamer @Twitter Software engineering, server operations & design will rule the roost”

“@engineers_feed I still love the 747. Epic plane.”

“@Rainmaker1973 Such an incredible engine!”

“As well as advanced chip & supercomputer engineers for next-gen training & inference”

“Note, this event is meant for recruiting AI & robotics engineers, so will be highly technical”

“@stevenmarkryan Pretty much. AI/robotics engineers who understand what problems need to be solved will like what they see.”

“@enn_nafnlaus @treygahigh @TaraBull808 @theliamnissan @RBReich Although his methods of instruction very strongly favored stick over carrot, I did learn a tremendous amount of engineering from him & appreciation of art (he is an extremely talented artist)”

“@BnOrdhaug @yasin_shafiei @thejackbeyer @NASASpaceflight @BocaChicaGal @NicAnsuini That’s the plan. We’re taking a little risk there, as engine isolation was done as retrofit, so not as good as on Booster 9.”

“@thejackbeyer @NASASpaceflight @BocaChicaGal @NicAnsuini Our focus is on reliability upgrades for flight on Booster 7 and completing Booster 9, which has many design changes, especially for full engine RUD isolation.”

“@Erdayastronaut @NASASpaceflight Booster 7 now returns to high bay for robustness upgrades & booster 8 moves to pad for testing. Next big test is probably full stack wet dress rehearsal, then 33 engine firing in a few weeks.”

“7 engine static fire https://t.co/sOm8Jx8rJq”

“@NASASpaceflight Chamber pressure looked good on all 7 engines”

“@SciGuySpace Yes, seven engine static fire”

“Won’t be long before we view gasoline cars the same way we view steam engines today”

“@CSI_Starbase Agreed, we recently made this change & many others. An intense effort is underway to achieve robust engine containment in case of RUD to protect booster, other engines & launch ring.”

“Adding the 13 inner engines https://t.co/ooOFEGl0Hr”

“About to attempt long duration engine firing to test autogenous pressurization”

“Hustling to get Starship Booster 7 back to pad to test outer ring of 20 engines”

“@RenataKonkoly @engineers_feed A classic 🤣”

“@engineers_feed I remember the 70’s, which means I’m definitely not spring chicken”

“@PPathole @Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Some small tubes & wiring need to be nested in a bigger tube for thermal protection, kinda like conduit in a house. Engines themselves & booster base are extremely robust. High strength stainless steel is bulletproof to a handgun at ~2.5mm thickness. Booster dome is 4mm.”

“@DJSnM @Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Electric power for booster & ship is needed even when engines aren’t running & incremental power draw of TVC isn’t too bad. We have local supercaps on each engine to deal with power spikes.”

“@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Enabling engines to take the heat without shrouds might save over 10 tons, all things considered. Shrouds are also a risk in that fuel leaks could be contained by the shroud, forming a MOX bomb. Booster is purging all 33 engine shrouds in flight to prevent this.”

“@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 All mass necessitated by an engine design should count as engine mass, eg shrouds, TVC hydraulic power or excess purge gas. Raptors in production now have electric TVC, saving over a ton of hydraulics mass on booster.”

“Was just up in the booster propulsion section. Damage appears to be minor, but we need to inspect all the engines. Best to do this in the high bay.”

“@ChrisDungeon @alexkehr @BillyM2k @levie Rereading The Life of Greece by Durant. In recent months, read American Caesar, Masters of Doom, Not Much of an Engineer, Wages of Destruction and Storm of Steel. Not much book fiction lately. Video games seem to have better stories these days.”

“@PPathole @planet4589 @NASASpaceflight That is one of the things we will be doing going forward. This particular issue, however, was specific to the engine spin start test (Raptor has a complex start sequence). Going forward, we won’t do a spin start test with all 33 engines at once.”

“@VladimirVargasM He did teach me a lot of engineering & physics while growing up (in an environment that was austere & often bleak)”

“@Rainmaker1973 You can see the whole engine moving to steer”

“@engineers_feed 🤣”

“33 Raptor rocket engines, each producing 230 metric tons of force https://t.co/flQLb62MgZ”

“@engineers_feed Civilization will be mostly solar-powered in the future”
