The Pico 2 board retails for $5 and, according to the Pi team, retains backwards hardware and software compatibility with previous versions. While the on-chip memory has been upped to 520KB – there is also 4 MB of on-board QSPI flash – the two RISC-V Hazard3 CPU cores included in the microcontroller may well interest…
I totally love this! A joule thief is a sort of minimum-component voltage booster that can suck nearly every last drop of energy from even seemingly-drained batteries, and is probably most famously used to light LEDs from cells that are considered “dead”.
While sales of petrol- and diesel-powered cars slumped in July, sales of fully electric vehicles and plug-in hybrids were up 37% compared to a year before. As a result, new-energy vehicles comprised 51% of total sales, according to the CPCA. For context, the International Energy Agency projects that electric models will account for one in…
Rails 7.2 introduced a new rate limit feature that uses the Rails cache for preventing abuse of routes in your applications. https://gorails.com/episodes/rate-limit-requests-rails-7-2
The Chinese have executed the low-end disruption playbook to perfection… cars is just *one* of the markets. This story is going to play out again and again. Driving China’s ascendancy is a massive and abrupt shift to electric vehicles. The EV share of total car sales will jump to almost 50% this year, up from…

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…
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…
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…
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…
