  • Mojave Sphinx — Half Cat Rocketry

    Mojave Sphinx is a high-power amateur rocket with a liquid bipropellant propulsion system powered by nitrous oxide and any number of solvent or hydrocarbon fuels. It is designed to be as simple and economical as possible so that an individual or team with high-power or experimental rocketry experience can build and launch it within a reasonable timeline and budget.

    you should be able to build a Mojave Sphinx for less than $2,000 USD, but that assumes everything is done in-house and you don’t contract out any of the machining.

  • How Far Might We Fall? - by Robin Hanson - Overcoming Bias

    Unless something big changes, world population will start to fall in a few decades, after which it will most likely rise again due to insular fertile subcultures like the Amish. Falling population should then cause a more than proportionate fall in innovation rates, though that would reverse if we developed ems or human level AI. And that might fix most culture drift! Innovation rates likely fall before population does, due to aging and Africa being less innovative per person.

    But even if population rises again, when will innovation rates rise again? Even if innovation activity stayed at the same levels of relative effort and effectiveness, its effect on the economy wouldn’t rise to its pre-population-peak level until the new economy rose to be substantially bigger than that level. But would innovation effort and effectiveness stay high?

    Modern innovation rates are quite unusual historically. There were a few known ancient bursts of innovation, but they didn’t last long. Even in the last few centuries most innovation has come from a small fraction of the world, and in some of those places innovation rates seem to have greatly fallen from their peaks. All of which suggests that innovation-supporting cultures are fragile, not natural, and easily disrupted.

  • Ashley Biden DNC Speech: A Personal Tribute to Her Father

    During her DNC address, as captured in the MSNBC video, Ashley Biden delivered a poignant and emotional tribute to Joe Biden, focusing on his role as a “girl dad.” She described how her father’s deep love and unwavering support have shaped her life, portraying him as a figure of strength and compassion. Biden’s speech was not merely a political statement but a personal story that aimed to resonate with voters on a human level

    Ashley Biden, the youngest child of President Biden, painted a more personal picture of her father, sharing stories of him as a parent and as a political figure. A social worker and activist, Ashley has largely stayed out of the spotlight.

  • Biden to 'pass the baton' to Kamala Harris at convention then jet off to California

    After his nighttime speech, in which he is expected to “pass the baton” to Vice President Kamala Harris, 59, Biden, 81, will trek over 2,000 miles west to Santa Ynez, Calif., where he will stay until Sunday, according to the White House schedule. The timing of his reported family vacation means that the highest-ranking elected Democrat in the country won’t be present for the remainder of his party’s convention this week. In doing so, he will avoid any risk of upstaging Harris in her hometown of Chicago, though it’s not clear that he would’ve outshone her.

    You know something? F--k you!" Barnicle replied. "And f--k all your friends with their anonymous quotes in the papers. Put your name on it next time!" And kept walking. A source familiar with Biden's reaction to the story told us: "He might still be laughing." Biden's friends tell us that as the president heads to his Democratic National Convention sendoff in Chicago tonight, he's somewhat relieved and pretty nostalgic — but also still stunned and pissed about the way he was pushed out of his re-election race.
