  • How Chile engineered the developing world’s fastest coal phaseout

    Chile is phasing out coal faster than any other developing nation thanks in part to regulations that bolstered environmental standards and gave investors the right signals, says former environment minister Marcelo Mena-Carrasco. In the first half of 2024, coal accounted for just 17.5% of Chile’s electricity output, data collated by research group Ember shows. That’s…

  • China’s Gigantic Airship Hangar Has Gotten Even Larger

    The addition to the hangar, which is situated near Bosten Lake in China’s Xinjiang Autonomous Region, can be seen in new satellite imagery that The War Zone obtained from Planet Labs. Construction of the original 1,150-foot-long and 450-foot-wide hangar, which is also extremely tall, started in 2013 and looks to have wrapped up in 2015. To give…

  • Uber deal could add 100,000 ridehailing EVs to roads

    This feels like a gigantic deal… not in numbers, but in impact. Uber is teaming up with BYD to bring 100,000 of the Chinese automaker’s electric vehicles to the ridesharing app. The multiyear partnership will roll out in Europe and Latin America first, giving drivers “best-in-class pricing and financing” for BYD vehicles used with Uber. https://www.theverge.com/2024/7/31/24210369/uber-byd-partnership-ride-hailing-evs That…

  • 2024-07-19-Why Do We Need Operating Systems?

    Yesterday’s computer problems mostly consisted of computation – using hardware to build fancier and fancier calculators. Typical uses for computers consisted of moon-shot calculators and military missile ballistics calculators. Today, though, the interesting problems are mostly asynchronous and distributed. For example internet, robotics, gaming, blockchain, GUIs, etc., etc. We need a new workflow which uses new notations…

  • Demo party on a chip

    The demoscene has provided our community with its artistic outlet since the first computers which could handle graphics, and has stayed at the forefront of technology all the way. For all that though, there’s a frontier it hasn’t yet entirely conquered, which exists in the realm of silicon. To address this [comes] the ever awesome…

  • Intro to Quantum Computing

    I thought it would be nice to put together my own introductory guide, and in the process improve my own understanding. After a lot of reading, and a lot of questions answered by my excellent colleague Dr Amy Hughes, I’ve put something together that covers some of what I was hoping. https://mcla.ug/blog/qc-intro.html

  • Secret NFC feature makes fabulous generative street art!

  • I got a rare look behind the scenes at Ananda’s e-bike systems factory in China

    You might not have heard of the company yet, largely because they rarely advertise which major e-bike brands use their motors, controllers, and other components. But to put things in perspective, they produced around 6.5 million electric motors last year. Most of their products are built for the massive domestic market, but around 600,000 were…

  • THE Z80 IS DEAD. LONG LIVE THE FREE Z80!

    [Rejunity] is bringing us an open-source z80 core on real hardware, thanks of course to the TinyTapeout ASIC project. The classic core will occupy two tiles on the upcoming TinyTapeout 7. While perhaps it’s not quite the same as a real 40-pin DIP in your hands, like all of the open-source custom silicon world, it’s as yet…
