@peterrhague The key point, is that Blue Origin is not at risk of bankruptcy as they iron out the problems like Space X was. There is therefore little doubt that they will become a major player soon. Of course, Starship could disrupt the market again.

The scenario of a successful booster recovery but not a successful payload delivery is to be expected when a rocket goes for reusability from day 1. SpaceX spent a while delivering customer payloads - and had some failures - before developing reuse. Their second stage was mature by the time they were landing boosters. Also, Blue Origin have picked hard mode for their upper stage using hydrolox.

The collection is called the Voyager series and considered as the most elegant microprogramming ever done, yielding powerful machines with minuscule resources. 15c is the best one, reissued as a collector edition 10 years ago when they updated the processor of the 12c which you can still find new. Bizarrely, the, at the time, cheaper and lesser 10c is the most difficult to find while the nerd wet dream 16c is easier to find in as-new condition probably because calculations in toctal or hexadecimal weren’t that necessary even then. I don’t dare use mine so I have a Swiss Micros replica on my desk. Classic Hewlett Packard pocket computers are a culture of its own. By the way, you need new feet, which can be found on eBay.

There were officially four Shuttle test launches. Two in 1981, and two in 1982. The Shuttle was so successful it made launches ordinary. Routine. A common blip on the evening news. Including a record nine flights in 1985 alone. Almost one per month! The country got so used to Shuttles going up we were shocked terribly when Challenger was destroyed by an SRB O-ring burn-through in 1986, and again when a damaged tile caused re-entry burn-through in 2003. Out of 135 flights across *three* decades of operation, those were the only failures. And it must be pointed out they were failures of the booster and external tank, respectively. Not the orbiter itself. The orbiter never took a life on launch, during space operations, nor glide-back, that wasn't the fault of the launch apparatus surrounding the orbiter. By contrast, Apollo CSM proper cost 3 lives on the ground, and almost cost 3 more lives in space, in less than 20 launches. The Shuttle was a magnificent machine. And if you don't want to take my word for it look at John Young's face as he performs his after-landing walk-around. The man who performed two Gemini flights, and went to the moon twice on Apollo, couldn't contain himself.

45 years ago today, astronauts John Young and Bob Crippen completed the first spaceflight of the space shuttle program, STS-1, landing Columbia at Edwards Air Force Base. Hundreds of thousands of spectators gathered in the California desert to witness the landing of the 98-ton (89-tonne) orbiter following its 2-day flight.

Quadcopters "crush" helicopter-style UAVs in real warfare (e.g. Ukraine FPV swarms) despite heli efficiency edge in hover/endurance: - Mechanical simplicity: Fixed-pitch props + direct-drive brushless motors vs heli's swashplate, linkages, tail rotor (100s of failure-prone parts). Quads build/repair in hours for $200; helis need precision machining, cost 5-10x more. - Redundancy: Lose 1-2 motors? Quad hovers/limps home. Single main rotor fail = instant crash. - Mass production: Hobby garages churn 10k+ quads/week. Helis too complex for disposable scale. - Agility/control: Instant thrust vectoring + easy software stabilization for dodging EW/fire. Helis' dynamics harder to autopilot at small sizes. - Disposability: Numbers win—lose 50 quads for 1 hit vs expensive heli. Helis shine for heavy/long-range, but physics loses to engineering for cheap, agile, swarm combat. Video shows cool tech, yet quads rule today.

Quadcopters dominate today because they’re cheap, simple, and disposable But physics hasn’t changed Electric helicopter style UAVs are far more efficient, carry more, and go farther As autonomy improves and cost comes down, we’ll see them play a much bigger role in warfare🤝

@peterrhague @Liv_Boeree “Discomfort” is an essential survival trait which developed very early in evolution. It would have to be reasonably unbearable to be effective, whether you want to call it “pain” or not.

@Liv_Boeree I don’t think there is enough mental substance to a crab for it to meaningfully suffer. Human empathy tends to get project much more cognitive capability on to animals than they really have.

@peterrhague Rousseau has a lot to answer for. Also modern education: all the fantastic, true adventure stories I read as a kid described nature as wonderful but absolutely unforgiving, which was easily confirmed by experience. What do they teach now and do people ever go outside to check?

Math Files@Math_files

During World War II, the U.S. military studied bullet holes on returning planes to decide where to add armor. Most damage appeared on the fuselage, so many thought it should be reinforced. Mathematician Abraham Wald pointed out a crucial flaw: the data only showed surviving planes. Planes hit in the engine didn’t return at all. This meant the engine was the real weak point. By reinforcing engines instead, many more planes were saved. The lesson: good mathematics isn’t just about numbers—it’s about questioning assumptions behind the data.

@RocketPulpHack @planefag I washed the inside of my first 4WD with a hose (only way to clean it) and left the doors open for it to dry in the sun. Nothing remotely like that these days.

@JohnLeFevre Brutalism comes from “Brut de beton” and was invented by Le Corbusier to save money on buildings. Who is the idiot who thought it meant you have to hurt the onlooker?

The Obama Library is the ultimate monument to DEI. The words are cut off. The Ts, Ls, and Is are indistinguishable. Looks like a trash can. Scheduled to open in 2021. Still not done. 3x over budget. Requirements: minority architect and contractors, stealing 20 acres of Jackson Park.

@SpaceKoala I was a kid when this happened. I don't care what the haters say. The STS was a revolutionary and remarkable system. Doesn't matter if the politicians overpromised. The STS ran for decades with only two failures. Amazing piece of machinery.

@AJamesMcCarthy Elon Musk has wisely chosen the path that was self-financing instead of one where he would have to pay for everything. As Starlink paid for Falcon, xAI will pay for Starship. Optimus will drive the need for inference even if the demand for Grok falters.

And since it keeps coming up, no, these are not "dresses". They are a dress uniform, but the most correct term would seem be "tunic". "Long coat" may also be accurate, depending on what's under them aside from the pants. How do I know more about attire than you squishies?

Gravity pull from the earth at the surface of the earth is 9.8 m/s². Gravity pull from the moon at the surface of the moon is 1.62 m/s² (and acceleration is helped by the absence of atmosphere). Gravity pull from the earth at the surface of the moon is 0.0027 m/s²; utterly insignificant. The influence of the sun is actually stronger at 0.00593 m/s².

@elonmusk This has always felt like the smartest play to me. Using the resources on the moon that are already outside Earth’s gravity well makes the rest of the solar system much more accessible.

There’s a difference between discussing the best tool for the job, which is worthwhile and should have a definite, statistically determined answer and the best toy to enjoy, which doesn’t, cannot and shouldn’t. My favorite pistol is a Walther TP, which has no practical use whatsoever but which I love to bits, I desperately wish I had a Leica Rangefinder which makes taking pictures 10 times more difficult and my favourite car is 60 years old and objectively undriveable. Let’s see what the Leica fanboys come up with…

I love owning and privately shooting. It's one of the great enjoyments I've developed as an adult which I did not have as a boy. What I don't love so much is Gun Culture™ which is too often typified by cliques, personalities, and attitudes which demand adherence to brands, calibers, cartridges, doctrines, etc. And if you aren't strictly adhering in the manner your critic insists, you're obviously an idiot, obviously have no experience, obviously have no business stating an opinion, etc. IMHO—and of course nobody has to take my word for anything—there's gotta be room in the discussion for taste, personal experience, and also personal comfort. If small arms really were a zero-sum enterprise there wouldn't be the menagerie of options available. Everyone would be buying and using the same few weapons in the same few calibers with the same few cartridge loadings. And it would essentially be a dead issue. The field would be monotonous and monochrome. But that's not the field as I've observed it. And outside of Cooper's rules—which are few and fundamental—what's worth being a dick about? Let people like what they like. And let people make up their own minds.

A while back someone I follow posted 'Let's give wheel guns some love.' I posted back that 'Wheel guns are more reliable for (reasons).' I then was hit with more replies to that simple statement than I'd ever had to anything I could possibly post. The 'reason' I gave was lambasted by @monsterhunter45 and various others. In one case by a 'former Delta' it was lambasted as 'Boomer fudd bullshit.' I've recently been watching a bunch of police videos. There is one particular pistol that in those videos, about half the time they fire it it jams. (Don't recognize it, not real up on modern pistols.) I've seen multiple other jams from other types but if I saw that one I'd avoid it like the plague. (In one case the reason it was jamming was given as 'the officer has a wounded hand so he cannot support the recoil well enough to stop the jamming.' This in the middle of a very active firefight. If your pistol won't auto-load because you don't have the perfect grip, it is NOT designed for combat. OTOH, saw that exact same model jam in multiple videos. So, I'm going with it jams alot. You know what very rarely jams? Revolvers. Because they are inherently simpler. Yes, much fewer rounds. They are much much simpler mechanisms. And what got me about ALL the replies, including Larry, was that these are people who have grown up in a very supportive ecosystem. The fucking gun culture in the US is so advanced compared to my day it's impossible to keep up with unless it's a full time job. But the EXACT SAME PEOPLE always talk about 'WTSHTF.' You wanna know what's going to be fucking working ten years after an apocalypse? Colt Python .357. Doesn't matter if it was made in 1979. (That's probably going to work better than one made today.) Know what's not going to be working? Your Super Omicron Uberpistolero 1000. That shit's going to have broken down in a year, four at max, without support. I know people who know people who do actual Third World merc shit. Kill people for fun and cash. They've all got Super Omicron Uberpistolero 1000. (Along with all the Super Omicron long guns, etc.) They all carry a revolver as a backup. (They also test fire everything before a mission. Which is something to keep in mind WTSHTF.)

Hello, I’m a Possum. Probably, you don't know it, but I’m not here to cause any trouble. Actually, I’m here to help. Every night, I can eat lots of ticks, along with other insects that spread disease. I also keep snake numbers in check, even the venomous ones. My body is tough enough to survive Rattlesnake or Coral Snake bites, and yes, I even eat venomous snakes like they’re just another meal. What’s more, my blood carries something special. Scientists have used it to develop treatments for snake bites that save lives. Without animals like me, there would be more pests, more Snakes, and fewer cures for people. Despite their bad reputation, they are much more helpful than you might think. So if you see them, please don’t hurt them. They are just out there doing their part to make the world a little safer for everyone.
