@BUSlNESSBARISTA @patrick_oshag I created a notion page listing the essays in the comments. I have organized them by themes and saved the links. https://t.co/auqfcuZZnv

believing in a singularity requires what @kevin2kelly calls "thinkism" – the belief that thinking really hard is the only thing you need to solve all the problems in the world

Charlie Munger, the Stoic: "Life will have terrible blows in it. Horrible blows. Unfair blows. It doesn't matter. And some people recover and others don't."

"There, I think the attitude of Epictetus is the best. He thought that every mischance in life was an opportunity to behave well. Every mischance in life was an opportunity to learn something. Your duty was not to be submerged in self-pity, but to utilize the terrible blow in a constructive fashion."

This is the time of year when a lot of investment firms welcome interns. While our work is geared toward institutional investors, a lot of it can be useful for learning about markets and the investment process. Here are a handful of reports and how they can guide interns:

Alex is right.

Grateful for the excuse to post this plot, which should be a bell curve of significance but is not because researchers are disincentivized to publish nonsignificant results.

This means you'll have fewer of the right negatives in public findings!

Latin America's avg birthrate has fallen since the 1960s but a recent acceleration has surprised almost everyone.

Brazil's census turned up 8 mln people fewer than expected. Paraguay's was 20% lower. "We'll basically have to plan for a new Paraguay," a minister there said.

NEWS: Tesla has started hiring for its Terafab (chip manufacturing) project in Austin, Texas!

Job listing: "You'll own end-to-end program scoping—including factory design/construction from concept through execution, ramp-up, and production readiness. The ideal candidate brings a strong background in technical program management, semiconductor facility engineering, multidisciplinary design leadership, value engineering, capacity modeling, and cross-functional execution for large-scale programs."

“What I was really good at was getting on the phone and collecting information…I could get on the phone with anybody. I was really good with it, and Larry [Robbins] put me in charge of building out the primary research team so I looked at the space and asked how do I create a competitive advantage? So how does the Street usually do it? Well analysts usually did three or four calls at the end of a quarter on their name and so I was like OK, they do 4 calls a quarter, I’m going to do 20 calls a month. I’ll do the 4 calls they are going to do and I’ll do 12 of those in a quarter and I’ll do the rest and at the end of the quarter I’ll have 60 calls to their four. And I’ll know if something is changing before they will and I’ll have a better sample so I’ll have less bias, and over time it will compound.”

The world's largest LNG plant hasn't exported a shipment in five days. That's the longest streak since at least 2008 🇶🇦⚠️

Qatar shut its Ras Laffan facility last week after a drone attack

The longer Qatar's outage continues, the tighter the market gets (and higher prices go)

LLMs process text from left to right — each token can only look back at what came before it, never forward. This means that when you write a long prompt with context at the beginning and a question at the end, the model answers the question having "seen" the context, but the context tokens were generated without any awareness of what question was coming. This asymmetry is a basic structural property of how these models work.

The paper asks what happens if you just send the prompt twice in a row, so that every part of the input gets a second pass where it can attend to every other part. The answer is that accuracy goes up across seven different benchmarks and seven different models (from the Gemini, ChatGPT, Claude, and DeepSeek series of LLMs), with no increase in the length of the model's output and no meaningful increase in response time — because processing the input is done in parallel by the hardware anyway.

There are no new losses to compute, no finetuning, no clever prompt engineering beyond the repetition itself.

The gap between this technique and doing nothing is sometimes small, sometimes large (one model went from 21% to 97% on a task involving finding a name in a list). If you are thinking about how to get better results from these models without paying for longer outputs or slower responses, that's a fairly concrete and low-effort finding.

We're partnering with @KhanAcademy to bring a suite of Gemini-powered learning and literacy tools to students, starting with the Writing Coach tool.

Writing Coach doesn’t generate answers or deliver a finished product — it walks students through the process of outlining, drafting and refining their own ideas. #BettUK2026

We’re launching full-length, on demand practice exams for standardized tests in @GeminiApp, starting with the SAT, available now at no cost.

Practice SATs are grounded in rigorously vetted content in partnership with @ThePrincetonRev, and Gemini will provide immediate feedback highlighting where you excelled and where you might need to study more.

To try it out, tell Gemini, “I want to take a practice SAT test.”
