    Did not have an identified serial killer until 1903. Both of these killers were white and killed white victims.

    I don’t think the police were really looking into crimes against black people in South Africa at the time. It’s entirely possible there were several serial killers that targeted non-white victims to avoid detection.


  • Wait, is it the same Adin that shot his Cybertruck and then got mad because he broke the door he was shooting at?

    I don’t know what confuses me more. The fact that he’s somehow dumb enough to do that, yet also capable of breathing and speech at the same time. Or that he probably has more money than I ever will because he’s that stupid.

    I want to reallocate my stat points.


  • All I’m gonna say is that ULAs Vulcan flew for the first time last month, and performed perfectly.

    Blue origin developed the engines for Vulcan, and they performed perfectly.

    Starship has had 2 test flights that they’ve had to backtrack and spin as “successful” because they cleared the pad. This is supposed to be a human rated launch vehicle, and it took SpaceX a few minutes on the second launch to even notice that the fucking thing blew up on the edge of space.

    I don’t really care how reliable the falcon is, when they haven’t seemed to apply a single thing they learned from it to Starship.

    Starship is supposed to put the next humans on the moon. They got the contract because they quoted to NASA that they could do it cheaper than anybody else. They’ve now blown up 2 test vehicles, and failed to demonstrate a single example of any of the new technologies they need in order for the Starship lander to work.

    Likely due to this, the next moon landing has been pushed back a year, and likely will keep slipping until NASA grows the balls to pull the contract from SpaceX and give it to a company with more realistic development strategies.

    As much as I am annoyed by the time table slip, What I really, really don’t want to see is the first people to land on the moon in 50 years crashing and burning because of Elon’s cartoon rocket. Or getting trapped on the surface because the stupid fucking elevator gets jammed due to moon dust. Or getting all the way out to the moon, only to discover the dammed turbo pumped engines won’t spool up after sitting in space for a week. Or if the thing will be capable of getting to the moon, we’ve never transferred cryogenic fuels in space before, and it’s going to take over a dozen of these transfers to fuel the starship for the landing.

    My point is that there’s 2 primary mantras when it comes to human space flight, and we’ve learned them through blood and sacrifice: Keep It Simple Stupid, and Failure is Not an Option. Starship, and SpaceX in general, fundamentally does not follow these. It’s already an over complicated and unproven design, and their whole design strategy is that blowing up is a success. That is unacceptable and contrary to developing a vehicle that is supposed to work 100% of the time while it’s 240,000 miles away. If you don’t design with those 2 goals in mind, you will get people killed, and we will have the very first bodies off of earth.

    To end this, I want to talk about some of the procedures that Apollo had. If they were going to leave the moon, and the ascent engine wouldn’t light, they still had options. Option 1 was to exit the lander, and flip a switch that would release a blade to cut safety wires that prevent the engine from lighting accidentally. If that didn’t work, they had a literal pair of bolt cutters, and would go in and cut the safety wires and bolts by hand before coming in and opening the valves for the fuel, which would light itself. Ask yourself what those emergency procedures look like on starship. Ask yourself what the procedure is if those engines won’t light, or the elevator jams with people on the surface, or any of the other dozen things that can go wrong and kill you in space.

    Who controls the streetlight blockchain in your idea? You think the government is going to responsibly manage a system that is large enough to be impractical to alter? My local government is barely responsibly enough to manage basic utility maintenance, we’ve had 3 water main bursts in a month and it hasn’t even been below freezing that whole time.

    I can’t believe a human being living in the world doesn’t see that any implementation of a secure blockchain requires massive funding for infrastructure. That money comes from 1 of 2 places, illegal enterprises that maintain control for security and manipulation, and legal corporations that will maintain control for financial security and manipulation. Modern governments don’t run projects like this anymore, they contract them out to corporations.

    Keep in mind that the only practical use of blockchain that anyone has found so far, has been as a currency that requires no ID. The most famous use of these currencies was by John Mccaffee, who used crypto currencies to help him evade authorities for nearly a decade. So I don’t have much faith in a technology that has only shown a benefit to criminals with so much money that cash becomes impractical. Nor do I have to remind you that wealthy private individuals have been able to manipulate crypto markets with hilarious ease, like how Musk pumped and dumped Doge Coin years ago with a single tweet and most likely made millions in private, untraceable money.

    Just because something sounds cool on paper, and makes it seem like it skirts governments and corporations, doesn’t mean it works in practice. Large entities inherently have more resources, and are primed to steal new technologies for their own use, especially when implementing that technology requires huge funding for infrastructure.
