> they gave me a job offer but withdrew it after I got badmouthed by a reference Why in the world would someone agree to be a reference and then bad mouth afterwards? Some folks...

Some places do "blind" reference checks, where they contact people you've worked with themselves (through Linkedin or similar.) The idea being that the references you provide are likely to be more positive than representative.

That seems open to abuse.

This is why I love the live streams hosted by John Innsprucker. He doesn't look like a TV star, he looks like an engineer, a rocket scientist. He looks real. The other hosts are great, but if you told me they were hired actors or PR people I'd believe it.

I went to school with one of the other hosts. He's legitimately a genius, top marks and well-decorated in academia. Kind of weird to see the guy I used to hang out with livestreaming to 2.3mm people.

And he's beautiful...

Some people have all the luck.

You're showing your biases here. The other people on the livestream are also rocket scientists. They aren't PR people. They just happen to be younger, or women, or of color. So you might want to re-evaluate what you think a rocket scientist "looks like", because your notion is outdated. Sorry to call you out like this, but these kinds of prejudices about who is the "correct" kind of person for tech jobs are harmful a…

> They just happen to be younger, or women, or of color. Maybe parent was referring to their mannerisms, rather than their appearance. It's not fair to jump to the assumption that parent was showing a bias against any of those variations in the human species.

To be pedantic, the poster did say "looks like" and:

- "looks like" is associated with physical appearance - possibly things like clothes, jewelry, gender, hair, skin color, face, etc. - "sounds like" is associated with their speech - tone, accent, choice of diction - "acts like" is associated with physical behavior + speech

But anyway, I think the point is that, we don't know what mabbo's intent was and 95% likely it was totally benign, but CydeWes is pointing out that saying things like that has a harmful effect by propagating certain stereotypes.

Pointing out someone's implicit biases is not necessarily a personal attack on them. Everyone has them so we should welcome when people point them out (unless done in an mean-spirited or aggressive fashion).

Personally, when I read mabbo's comment, I thought, "Yeah, so true, good point!", then I read the next comment and I thought, "Oh right, thanks for pointing that out to me".

I upvoted you, but I think it’s important to recognize that unconscious biases often manifest in exactly that way. White men have made up the majority of the scientists and engineers we’ve been exposed to in the past, so we associate the mannerisms of white men with them. Women and POC haven’t, so we don’t associate traits common to them with the persona we expect of those professions.

Sure, new mannerisms serve to flag people as scientists and engineers. But again, you're implicitly both assuming, and accusing the parent of, bias (against women, minorities, and young folks). Not only that, but there isn't any defense after you involve the 'unconscious mind'.

I think right now the car is in a low Earth orbit. There will be a second ignition of the top stage later to shift it to the Mars orbit. The timeline ends with… Mission continues on an experimental long coast and third stage two burn to target a precessing Earth-Mars elliptical orbit around the sun … which I can't completely decode. Update: SpaceX says "Upper stage restart nominal, apogee raised to 7000 km. Will spen…

The target orbit will be a ellipse around the sun. The closest point to the sun will be about 1AU (Earth-Sun distance). The furthest point from the sun will be something like 1.5AU (Mars-Sun distance). This orbit will precess, meaning that it will slowly rotate its axis around the sun, rather than staying locked into the exact same path.

This. AIUI, they didn't bother setting up the "spacecraft" as an actual deep space probe, and it's likely missing electrical power for an extended mission, plus all of the hardware necessary to orient itself, track time and position, perform further burns to insert into Mars orbit, and communicate with Earth about all of that.

That was the new Tesla that just was announced. I assume he hasn't been driving it for years.

You're mistaken; it's one of the original-style Tesla roadsters, not the newly announced model. You can see an image of the payload here [0], and of the new model here [1].

I'm just an amateur following along, but this seems likely to be one of the most important launches in modern rocketry history. This sets the stage for deep-space missions with reusable launch materials, which can greatly reduce the cost of future space exploration. Absolutely incredible achievement by the SpaceX team.

This definitely feels incredibly significant. The Soviet Union tried and failed 4 or 5 times to launch a rocket with this many engines, but now we're able to nail it on the first try aaaand land the boosters.

Well, but to be fair to the Soviets, they had to do it with really "stone age" electronics and technology and not knowing the many things we know today.

I am pretty sure that SpaceX was able to achieve what they did today also because they studied the Soviet N1 rocket and learned from what the engineers at that time had to figure out from scratch.

The other thing is that the N1 Moon rocket was a very different design - a single booster with many small engines, so incredibly difficult system to control, especially given the state of technology 50 years ago. Falcon Heavy is more similar to the successful Energia booster - core + strap on boosters - that was originally designed for the Russian shuttle. Or the Angara series.

Fuck Snapchat filters, fuck another JavaScript framework being released, fuck Google releasing another chat app, fuck the next iPhone having wireless charging.

This is innovation. This is the future. This, and Tesla, are the biggest technological breakthroughs since the iPhone.

There was something doubly awesome about the two falcons landing at the same time right next to each other!

Can confirm this was the greatest thing I've ever witnessed in my life. https://youtu.be/AGPH_i0ZlyM?t=56

I get a headache watching Star Wars like sci-fi where everything is manually controlled by the pilot. How did sci-fi get so disconnected from the actual future?

When I saw the first successful booster landing I realized I was seeing history. When I saw the first successful booster landing on a drone ship I realized I was again watching history.

And there's still more! Live Webcam from Spaceman: https://www.youtube.com/watch?v=aBr2kKAHN6M

All of this insane expense and amazing science and they couldn't make a VR360 camera happen. :(
