Smartwatch Hypertension Alerts Shouldnโ€™t Replace Screening Receiving an alert increased the probability of undiagnosed hypertension, but absence of an alert did not reliably rule it out and should not replace cuff-based screening.

If you get a hypertension notification on your Apple Watch, you should heed it and follow up with your physician. Lack of an alert, however, doesn't mean you don't have it. My latest at Medscape. #medsky #hypertension

Same. Never met a truly aloof cat in my entire lifelong obsession with cats.

Note: a time-tracking app has been invaluable in watching where my time goes and helping me make decisions about what my time is worth and what is worth my time. Very much recommend

signing contracts, purchasing business insurance, attending Dr. appointments, calling tech support about various website glitches, making a second trip to Dr to pay because the insurance portal was down, gathering tax info, filling out tax forms, emailing editors and sources, record keeping, etc.

One would imagine that as a freelance writer, I would spend most of my time feverishly typing on various projects, and that's what I would like it to look like. In reality, much of my time today and this week has been gobbled up by "freelance admin" and "household admin." Some of those tasks:

If the writing or "research" you do involves reading hundreds of sources and pulling it together with a new angle, I can see how AI would help. But it's incorrect to generalize and insist that others saying, "No, thanks," are misguided. The best use cases for AI are specific to the task.

Intent and precision are required to communicate the ideas properly. To the average person, the output of an AI is smooth enough that they can become convinced that it fully replaces human work. But for skilled writers, its output is often worse than starting with a blank page.

A piece of writing produced by AI is written to resemble something that would best conform with the prompt it was given. This is why AI doesn't replace human writers. For use cases where a simulation is sufficient it serves. But in most cases...

The human writer is not just choosing a word that is statistically likely to come after the ones already written but looking for EXACTLY the right word every single time. When done well, a story, an article, an essay, is written with precision.

the more random the next word choice. Make the temperature too high and you get nonsense. Instead, a human writer starts out with an intention. That could include things like meaning, emotion, metaphor, resonance, rhythm, rhyme, humor, and other characteristics...

The number of preceding words it can use for the prediction depends on the model and the size of the "context window." So as not to produce completely boring output or to reproduce works in whole from its training data, an LLM includes a variable called temperature. The higher the temperature...

Having mulled this a while, it comes down to the word "research," which is used very differently in different contexts, and it highlights for me the key difference between writing produced by a LLM and writing produced by a human. AI predicts the next word based on the words that have come before..

This is a worthwhile read

That is a very interesting take!

Squirrels like to help. Sometimes they'll bring over bulbs from your neighbors.

I have a red/infrared light wrap and I use it for everything. Though nothing but time truly helps DOMS, I find it soothing.

I'm increasingly wondering what the AI hype men want from the rest of us. "Things are changing fast!" Yes, and...?

Please forgive my ignorance. In this context, what does "generating research" mean? To me it sounds like reading papers and then writing a new paper about what you read. I would agree that careers involving synthesizing prior works into new papers or powerpoints, etc., would be more amenable to AI.

I have known people who chase the poly life to the detriment of literally everything else, including their kids, their health, and their bank accounts.

We are Jammer's "furever home" where she gets to be doted on as a pet. But the breeder still has puppy plans for her, which is why I'm panic shopping for dog undies right now. Eeek! It's our first time dealing with this (and we expected it 1-2 months from now). Advice welcome!

I decided I would do just fifteen minutes a day on taxes until it's all done. Five hours later, it's almost all done...

I still iron stuff. Now it's like magic, because no one understands why your button down top is smooth. muwahahaaha

It worries me in general people do not seem to understand the distance between opinion and news reporting

Agree 100% and yet the brilliant Project Hail Mary starts exactly this way. I will never attempt it, myself.
