@Mark_Graph That seems like an invocation of the No True Scotsman fallacy to me.
Nonetheless the right measure to chart would be retail dollars spent per KWh consumed at home. I’d be interested to see those data if it existed (which I doubt, since all-home consumption isn’t tracked AFAIK)
English

The CPI electricity series measures retail prices paid by households on the grid. It doesn't capture the implicit savings of households who've gone solar. But that cuts both ways: the households who can't afford rooftop solar, who rent, or who live in apartments are the ones actually paying these retail prices, and the chart shows what's happened to them.
There's a bigger structural point. Retail electricity prices reflect generation, transmission, distribution, and retail margins. Even if wholesale generation costs have fallen due to renewables, network costs and the costs of integrating intermittent generation (firming, transmission upgrades, capacity payments) flow through to the retail bill. The "cheap green electricity" promise was generally pitched as a retail outcome for consumers, not a wholesale-only metric or an "if you can afford panels" metric.

I have not laughed this hard in a very long time.
Hang up your meeting and listen to this 🤣🤣🤣

The Sam Altman and @miramurati texts from the day he got fired from @OpenAI in 2023 just became evidence in the @elonmusk v. @sama trial. It felt like a meaningful moment in AI history, so I turned it into a musical. The lyrics are the texts.

@AndyMasley Solar radiation of course. It’s right there in the name!

It’s been a tough stretch with GitHub availability.
The feedback isn’t wrong. People depend on us, and we haven’t met that bar.
Just know there are humans on the other side of this, reading all your comments and working as hard as we can to improve it. github.blog/news-insights/…

Why the weird discontinuities at the :00 and :30 times? Physiology doesn’t care about clocks, so is it an artefact of training?
John Bistline@JEBistline
The 2-hour marathon was this generation's 4-minute mile. People debated whether human physiology could do it. The once-inconceivable achievement was broken today not by one runner, but two! Sabastian Sawe just ran 1:59:30 in London.

Four photos of Wimbledon’s Centre Court show how tennis has shifted: from grass worn across the whole court (serve-and-volley era) to damage almost only at the baseline today. A slower, power-driven game played from the back.
The 1970 picture (top left) shows the grass played to a pulp all over the court, from baseline to net. In 1980 (top right), turf damage is visible in a T-shaped zone beyond the baseline. This damage to “volley valley” largely evaporates by 2005 (bottom left). By 2023 (bottom right), the service boxes appear entirely untouched, with only the baseline area showing wear and tear.

Saw the EML paper blowing up yesterday so I thought: “What if I build a full LLM inference engine with it?”
So I did.
Meet emilio — an end-to-end inference engine where every single multiplication is replaced by the EML primitive:
eml(x, y) = exp(x) - ln(y)
No *. No +. Just this one wild operator (plus the constant 1) powering all the math: linear layers, attention, everything.
It runs Qwen2.5-0.5B-Instruct (494M params) completely in EML and actually generates coherent text.
→ ~5.5 tok/s on CPU
→ ~30 tok/s on Apple Silicon GPU
Not competing with llama.cpp on speed. This is pure proof-of-concept: showing the math actually works at transformer scale.
A celebration of mathematical minimalism in the LLM era.

If you like weird math, extreme minimalism, or just watching someone go “hold my beer” after reading a paper… star it ✨
