Breaking SolidJS 2.0 Beta
Breaking SolidJS 2.0 Beta I'm pretty excited to have the beta released. But because it was built with extremely powerful primitives even I don't know its limits. The combinatorics feel like it could get us into crazy places bu...

Solid 2.0 is so powerful even I don't know the limits of its capability. Join me Friday when I try to break it:

I released an article I wrote a month back. I didn't previously publish because, on early review, it wasn't the article people expected from me on AI (today's stream will be). But I want to get this out there as it captures my first impressions:

GitHub just silently cancelled all our outgoing sponsorships from @voidzero.dev - not sure what happened.

I just manually re-sponsored everyone we were sponsoring.

Granted, twice those β€œbenefits” I mentioned were because the entire team was excited about a new tech and the stack needed to modernize from 2001 version of Cold Fusion or vanilla JS to a typescript framework

Anytime one intrigues me for my personal projects. At work, I’ve done this only rarely in my career and only because the benefits in relation to project requirements outweighed the costs of the learning curve and the maintenance of a tech non standard to the organization.

npmx - Package Browser for the npm Registry a fast, modern browser for the npm registry. Search, browse, and explore packages with a modern interface.

The keyboard shortcuts on npmx.dev provide the experience every site should strive for. It’s so easy to do everything I want to do without my fingers ever leaving the keyboard.

GitHub - jesseduffield/lazygit: simple terminal UI for git commands simple terminal UI for git commands. Contribute to jesseduffield/lazygit development by creating an account on GitHub.

I’ve been using the plain ol’ git CLI for over a decade. Just never liked GUI tools bc of the way they change terms. Like what does it mean if I click β€œrefresh” on a branch? Does that do a git fetch and merge? Only when it can fast-forward? Idk.

Enter LazyGit. I love it.

Lowest setting. CSS powered flamethrower!

Yes, it is really controlled by CSS. I can add MIDI inputs. Then use CSS to trigger animations and output the result to DMX for controlling the flamethrower.

No, that’s true. My point is that solar’s economics isn’t the only topic worth discussing. Areal density doesn’t seem to meaningfully impact the economics, but land use, waste, and habitat destruction are central issues that even IRENA anticipates and reports on.

09.10.2025 18:37 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

That’s true but cost per kWh is not the only issue. It takes acres and acres of solar panels to produce relatively little energy in terms of the average demand per household. That model simply doesn’t scale. Only efficiency improvements can mitigate that.

09.10.2025 18:16 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Hence, why I named efficiency as the main issue.

09.10.2025 17:44 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

With greater efficiency, fewer units can be used to yield the same output which drives down the cost per kWh.

09.10.2025 17:25 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

So what? You literally said it was the amount that matters and I responded accordingly. According to the U.S. Energy Information Administration, energy-related COβ‚‚ emissions have steadily decreased since 2007. There was a slight regression in 2019-2022, but trending downward again since then.

09.10.2025 17:21 πŸ‘ 1 πŸ” 0 πŸ’¬ 2 πŸ“Œ 0

Re-read what you wrote, but slowly. Cost per kWh can’t be important while efficiency is irrelevant. Greater efficiency is what improves cost per kWh and that’s why the bulk of the research is going into improving efficiency of conversion and production.

You might be interested to know that China burned 3x more coal per capita in 2024 than the U.S. did.

4.6 billion tons of coal with a population of 1.409 billion = 3.265 tons per person

372.3 million tons of coal with a population of 340.1 million = 1.095 tons per person

09.10.2025 15:47 πŸ‘ 0 πŸ” 1 πŸ’¬ 1 πŸ“Œ 0

That’s fair. China consumed appr. 55% of the global thermal coal (amounting to 4.6 billion tons). The U.S. consumed 372.3 million tons (which was a decrease from 2023). In other words, China burned 12 times more coal in 2024 than the U.S. did.

09.10.2025 15:40 πŸ‘ 2 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

China has also brought about 300 more coal power stations online since 2023 and has a total of 1195 as of July of 2025. The US has 200.

China is simply creating as much energy as possible by any means necessary in an attempt to meet their growing energy demand.

09.10.2025 13:43 πŸ‘ 4 πŸ” 1 πŸ’¬ 2 πŸ“Œ 0

China produces the most greenhouse gases, primarily due to its reliance on coal and other fossil fuels. While US is in second place, China has a lot of work to do to reduce their emissions as much as the US has. China isn’t leading the way, it’s trailing but making considerable strides.

09.10.2025 13:15 πŸ‘ 4 πŸ” 1 πŸ’¬ 2 πŸ“Œ 0

At this point, without significant technological advancement, nuclear fusion appears the only viable way to meet the rapidly growing energy demand throughout most of the US. Modern advancements have made it a very clean, renewable energy source.

There is potential. I’ve been following photovoltaics for 20 years. Even made a rudimentary (and VERY inefficient) photovoltaic cell just for fun. The issue is that even the best are still relatively inefficient. Wiping out forests I used to explore for acres of solar panels feels dystopian
