Ah, memories. At my first real job, my desktop machine was an HP-UX workstation with a monochrome monitor. The company did UNIX CAD software, so each developer got a different type of system to ensure we developed on all the platforms we su

The article only talks about LA becoming coal free. It looks like there is still a very small amount of coal used in other parts of the state: https://www.energy.ca.gov/news/2025-10/trump-embraces-dirty-... coal’

Wrote a mini adventure game in BASIC for the ZX-81. Since it only had 1K of RAM, each room in the game had to be a separate program (max around 25 lines of code or so), and at the end of the room, depending on what actions you took, it aske

Who owned these key LFP patents? It was not clearly laid out in the article which countries owned them, let alone which companies. If they were owned by Chinese companies, then is there some faint hope that Western companies can finally sta

I'm in Beijing right now. I was also here 20+years ago. The difference is astonishing. Back then the air was filthy, it was hard to breathe, you never saw the sun. Today it is blue sky most days, EVs everywhere, electric scooters, buss

I keep hearing this argument (that China does not care about climate change or the environment so it must be doing it for other reasons) but I just don't understand it. Why would you think they don't care about these things? The C

Took Amtrak from LA to San Jose last week, which was a good experience. The train runs along the coast for a good stretch, from Ventura through Vandenberg and then through the hills. It's certainly not the fastest way to go (~10 hours)
