Does anyone know of any macos transcription apps that allow you to do speech to text live? Eg, the text outputs as you are talking? Older tech like the macos dictation as well as dragon does this, but seems like theres nothing available that uses the new, better models.

Wow, when I was a kid back in the early 2000s, howstuffworks was my favorite website. I bet I read every article on how various things work (there were many hundreds).

I found that the knowledge from that website helped me understand how everything in the world worked and satisfied my curious mind. I attribute my knack for understanding new things and fixing things to this website.

Back then, the site was clean and had very good clean and expertly written explanations of how various mechanical, everyday and scientific equipment worked. Nowadays that website is not the same, seems riddled with SEO spam and fluff articles like a content mill.

Rest in Peace Marshall Brain, thank you for all your contributions to my (and likely others) life

That is very location dependent as you need to transport water to where it's needed. Mining can happen almost anywhere.

Is this even an issue? Presumably without a steer by wire system a human would not be able to turn the wheel this fast. Also the delay looks longer than it actually is because of the slow-mo. Say this is playing at 25% speed and it is delayed by 1/2 a second, that means at regular speed the delay is only 125ms.

I'm not arguing whether the use of electricity is compelling or not.

I'm arguing that the unique energy demand characteristics of bitcoin mining allow it to support building renewable energy projects and balance electricity costs and thus it has effective positive contribution to the environment.

Whether it's used to mine bitcoins or cool a house is irrelevant, except that the demand for cooling a house is location and time sensitive, whereas bitcoin mining is cost sensitive. This flexible consumption gives it unique properties that support deployment of renewables.

Please explain what you mean by "false economy". Is the economy for skins in a game you don't care about "false" because you don't like that game?

Leaving stuff on when you are away is completely different than how bitcoin mining demand response works.

Firstly, at regular electricity prices, bitcoin mining is profitable and it is profitable for the utility to run renewables (which in turn means it is/was profitable to build renewables). When there is substantial demand or low supply, then it is profitable for the utility to pay the bitcoin miners to turn off, because the alternative to import power is more expensive. This in turn makes your electricity cheaper. In addition, the additional steady state demand for power allows for more renewables to be built, which further increases the supply during low supply periods. Your AC does not automatically turn off when this happens.

I am one of those enthusiasts making "strange logic" claims. I've been making this claim well before others but I feel that I keep getting downvoted on them off of people's emotion rather than rational logic.

The transition from fossil fuels to renewable energy sources has altered the environmental impact of additional electricity consumption. Where once any increase in consumption was considered harmful due to its reliance on fossil fuels, the rise of renewables introduces scenarios where the marginal environmental cost of electricity can be beneficial if the demand is flexible.

Bitcoin mining has the potential to act as a load balancer for the electricity grid. By increasing its energy consumption during periods when renewable energy production exceeds demand, and reducing consumption during peak demand periods, Bitcoin mining could help stabilize the grid and make renewable energy generation more economically viable.

Bitcoin mining's demand for electricity is unique in that it is primarily cost-driven. Renewable energy generation capacity is particularly volatile. Bitcoin mining power usage can be flexible and responsive to the availability and cost of electricity.

The ability of Bitcoin mining to consume excess renewable energy when it's available (and potentially at low or negative prices) could improve the financial viability of renewable energy projects by increasing the floor price these new projects can sell electricity at. This can encourage the development of additional renewable energy capacity by providing a reliable demand for their output during otherwise unprofitable periods.

Has anyone looked into the theory that SO2 is an "anti-greenhouse" gas and that much of the greenhouse effects of CO2 have been negated by SO2. Essentially SO2 particles stay in the air for a long time and reflects a large spectrum of light so it fails to be absorbed by land or sea/converted to infrared (infrared is primarily what the CO2 reflects).

Recently (since 2010ish but moreso since 2020 in shipping) there has been a global effort to reduce SO2 emissions (eg by installing scrubbers) which has caused the CO2 increase over the last 150 years to actually "take effect" since the SO2 is no longer negating the effects.

I stumbled upon this theory recently and it sounds compelling but am curious if better informed people could shine a light about this.
