AI summaries for Google search are particularly insidious because pre-AI snippets came with the website details, and I could do a quick scan to find the most trustworthy website to pick an answer from. Now not only are the search results tanked, but also impossible to reliably do a "quick" search.

Britain breaks solar energy record twice as UK’s biggest solar farm gets approval Record high set on Monday and raised on Tuesday, with 14.4GW of electricity generated in sunny spring weather

A single line in this piece just made my day:

“The electricity system operator is understood to be preparing to run the grid without any gas for short periods as soon as this summer, in a first for the UK energy system.”

Renewables *work*. And progress matters🎉

Howarth and Jacobson respond to Zeke's post. They ignore his substantive argument about the merits of GWP-20, focusing instead on the importance of near-term climate action. But the case for GWP-20 shouldn't rest whether we like the policy outcomes it produces.

Terminal text from a Claude Code session:

Coding with LLMs like Claude Code is fun and fast, but for scientific codes one has to be super careful that the LLM did not mis-interpret your intention which is always stated with some ambiguity.

question is not whether the feed is AI-generated, but whether it does what you want it to do. Using AI for feed curation (or coding) is not the same as using it for writing; the latter is justifiably more controversial. 4/4

As a quantitative scientist who is developing a transparent simple statistical feed (called Skylimit) that is deliberately non-AI, I would like to defend/explain the place of so-called AI feeds in the ATmosphere. I consider AI to be just very sophisticated and opaque statistics. Some of the 1/4

This is excellent. I choose not to use AI for my writing, but Naomi's piece reminds me that I'm in no position then to make uninformed judgements about its potential.

Indeed, that's the issue. I use Wise and the like for large money transfers. But for sub-dollar micropayments, fractional bitcoins or stable coins are the only viable option. I've been looking into micropayments for Bsky. The technology exists but the economics is tough.

I recently added the card feature to a web page and tested that it works with Bluesky. It is indeed the Open Graph (OG) metadata tags in the html. Usually your blogging software generates the OG metadata.

Yeah. Relying on AI too much makes you dumb.

My graduate Statistics class is making statistics-related memes for extra credit.

It's a fun time of year for sure!

This is the app that does volume filters: https://blog.skylimit.dev
It probabilistically limits the number of posts for each follower.
It also does followee-specific keyword filters.
It would be easy to add timed mutes, if it's of interest.
The app's usable but still fragile at this time (I use it)

There's a lot of truth to what you say. But professionals like journalists and bloggers may be willing to classify a post if there is a guarantee that their followees will be shown that particular post, instead of showing a random less impactful post. Skylimit provides such a guarantee

That's the exact issue I'm trying to tackle with https://skylimit.dev There are two ways to do that. 1) Convince posters to classify their posts using hashtags (so that more followers will see relevant posts) and/or 2) Readers specify what keywords they want to see in in posts shown from a followee

Maybe Bluesky will get mad at me for saying this, but this is a bizarre headline because if you actually read the article it says the exact opposite.

Please consider reading the whole article before doom-sharing the irresponsible headline.
