Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004.
Today, building a fence with solar can be cheaper than using wood.

Australia has so much electricity from solar power that it is going to start offering free electricity to everyone for at least three hours during the day as the wholesale price of power goes negative

Australia's extensive solar power penetration makes so much energy that the government wants to offer free electricity at peak hours.

I'm quite pleased with this - I've been training for a 10 km run and I thought I'd dig in to what my #Strava data could show me.
I used the #rstats package rStrava to pull my data and built myself an R Shiny dashboard to produce some analyses.
Rather than share the dashboard with its API tokens

I will try to do a tweetorial about this paper when I have more energy but this is really important data. It looks (tentatively, preliminarily) that COVID-19 mRNA vaccines might significantly enhance the effectiveness of cancer immunotherapy (subject to many caveats).

Really interesting paper on semi automated surveillance of surgical site infection. Interesting to note value of including number of blood culture requests as predictive factor - not normally collected in SSI surveillance.

Hoping to make it to >=500 km by end of December.

If Garmin and Strava properly fall out, it's going to really scupper my run -> Garmin -> Strava -> #rstats shiny workflow. And that will be really disappointing.

Great thread about what read like a dodgy article.
Asked lots about this piece on Chronic Lyme disease, and disappointed in the @guardian (a publication I both subscribe and contribute to) for running it. Short thread explaining the multitude of problems with it, and why I consider it irresponsible to run as is..🧵

Yes! Coding is thinking. My new rule of thumb: Use a LLM only to write code to do things that either are low priority or that I don’t have time to do and wouldn’t have done without LLM (while assuming the generated code is only 80% right).
