Something happened in year 774 that was so powerful we can measure the radioactivity in old tree rings. Best guess is a solar flare, 10 times more powerful than the Carrington Event in 1859 that zapped telegraph wires. Worth considering the effect of the next one. Details:

My textbook now includes an updated figure from Carter & McCullough, 2014. It's now generated from the raw data. It's a striking image. The uncorrected effect size is d = 0.62 based on 198 studies. Now, large replications later, we know the true effect size is 0. What a waste.

Adam, a 9-yr old optimizer, is the go-to for training LLMs (eg, GPT-3, OPT, LLAMA). Introducing Sophia, a new optimizer that is 2x faster than Adam on LLMs. Just a few more lines of code could cut your costs from $2M to $1M (if scaling laws hold). https://t.co/GrMY600lLO 🧵⬇️

Another example: Take two glasses of equally sweet water and mix them together. Children of intermediate age think that the resulting solution will be sweeter than the originals! Similar results have been found for water temperature.

The shift to WFH is the largest shock to labor markets in decades. Pre-pandemic WFH was trending towards 5% of days by 2022. Now WFH is now stabilizing at 30%, a 6-fold jump. In America alone this is saving about 200 million hours and 6 billion miles of commuting a week.
