New comment by joak in "The climate benefits of retiring an operational combustion engine vehicle"

joak — Mon, 10 Aug 2026 12:46:02 +0000

There is an element I haven't seen in this conversation: as the number of combustion engine cars goes down the number of gas stations also goes down. At some point, combustion engine drivers will start feeling range anxiety. So when you get rid of your fossil-fuel-burner vehicle, you are pushing others to do so.

The full calculus of CO2 emissions reduction should also include the reduction induced in others.

New comment by joak in "What is a quantum computer good for? nothing – yet"

joak — Sat, 04 Jul 2026 18:58:27 +0000

Google had a paper last year explaining that: https://blog.google/innovation-and-ai/technology/research/us...

We do not have any useful algorithm to run on a quantum computer.

The problem is not that we do not have yet quantum computers powerful enough, but that even if we had such computers we would not have anything useful to run on them.

You could use this audio at 300 baud by recording it on a standard audio cassette. Then play the audio back as input to the modem to retrieve the data

Actually in 1982 I was able to store my programs on standard audio cassettes. Hardware needed: a modem and a cheap tape recorder. My apple II modem would chirp the ascii binary like Starwars' R2D2, I'd record that and when needed I'd play it back to the modem.

I agree, this report from astronaut Camarda should really alarm NASA.

The DJI ROMO robot vacuum is amazing. It shows what can be done with today's technology.

My Roomba is just crap compared with DJI's. I'm not surprised they went bankrupt.

Excerpt: “The fact that it’s been 3 years since ChatGPT first launched, and you’ve only just now managed to make it obey this simple requirement, says a lot about how little control you have over it, and your understanding of its inner workings,” wrote one X user in a reply. “Not a good sign for the future.”
