  • NASA Selects a Wild Plan to “Swarm” Proxima Centauri With Thousands of Tiny Probes

    Their proposal calls for a 100-gigawatt (GW) laser beamer boosting thousands of gram-scale space probes with laser sails to relativistic speed (~10-20 percent of light). They also proposed a series of terrestrial light buckets measuring a square kilometer (0.386 mi2) in diameter to catch the light signals from the probes once they are well on…

  • Rabbit sells out 10,000 units of its R1 pocket AI companion in one day

    Holy shit, this is awesome! A stark contrast with the other AI companion company. A shake up of the current model is desperately needed. We’re beyond diminishing returns and into incumbents holding on for as long as they can make money. This is a bright spark. The R1, the pocket-size gadget from Rabbit that’s supposed…

  • After its impressive first flight, here’s what’s next for the Vulcan rocket

    The Dreamchaser launch is gonna be fun to watch.[SPOILER] Vulcan’s debut was much-anticipated in the US launch community because the rocket provides a potentially viable competitor to the Falcon 9 and Falcon Heavy rockets flown by SpaceX. The US Space Force, in particular, has been waiting on Vulcan to fly dozens of payloads into orbit.…

  • Pluralistic: Kelly and Zach Weinersmith’s “A City On Mars” (09 Jan 2024)

    the Weinersmiths aren’t anti-space. They aren’t even anti-space-settlement. Rather, they argue that the path to space-based scientific breakthroughs, exploration of our solar system, and a deeper understanding of our moral standing in a vast universe cannot start with space settlements. Landing people on the Moon or Mars any time soon is a stunt – a…

  • Missing the point of webassembly

    I have a different preferred starting point which is less descriptive but more operational: WebAssembly is a new fundamental abstraction boundary. WebAssembly is a new way of dividing computing systems into pieces and of composing systems from parts. https://wingolog.org/archives/2024/01/08/missing-the-point-of-webassembly

  • CH32V003 FM Radio Receiver with RDS

    With the portable Li-Ion battery powered FM radio receiver you can listen to your favourite radio station. This device is equipped with cost-effective components, including a CH32V003J4M6 32-bit RISC-V microcontroller, a RDA5807MP FM radio tuner IC, an audio amplifier (TC8871 or XPT8871), a 128×32 pixel OLED display (SSD1306), and a Li-Ion battery charger (TP4054 or…

  • How the US is rapidly cleaning up its biggest form of mass transit

    The US Environmental Protection Agency (EPA) has now allocated enough funds to replace more than 5,000 of the country’s school buses with zero-emission alternatives.

  • It’s Humans All the Way Down

    If you could sum up what we learned in 2023, and I think what tech has learned, too, is that people matter. Even in the wildest of innovations, people still matter, and human relationships still matter, and you can’t shortcut it. – Rich Ziade, Aboard Podcast https://blog.jim-nielsen.com/2024/humans-all-the-way-down/

  • PICO-56 – Introduction and Giveaway!

  • What I learned from using a Raspberry Pi 5 as my main computer for two weeks

    But maybe the Pi 5 will be better! Looking at the spec sheet, things seem promising: “between two and three times” the CPU and GPU processing power of the Raspberry Pi 4, faster interfaces for storage including the option for an internal PCIe SSD, and support for a pair of 4K displays running at 60…
