This is one of the few HN articles that have profoundly moved me. Such a beautiful and simple use of technology to make a clear and big improvement in someone's life. As a side note on his mother remembering that the tablet exists, it sounds like she has amnesia quite like Henry Molaison, a famous case study in neuropathology. He had very specific brain damage that seemingly stopped him forming new memories in the sa…

Further than just muscle memory, every cell in our bodies actually has "memories". That's why heart transplant patients can experience personality changes from the donor: https://www.sciencedirect.com/science/article/abs/pii/S03069...
Excuse my ignorance in asking, but is this trustworthy? I'm a layperson regarding biology and I was always assumed that organs outside of the brain don't contribute to memory. At the end of the article is the statement "Data not available / No data was used for the research described in the article." Is it possible to see the data? Reddit is telling me to not accept it at face value - https://old.reddit.com/r/researc…
> organs outside of the brain don't contribute to memory
Interesting question. To start, personality typically refers to the totality of a person's behaviors, not the memories they may be able to bring forth. Behavior, esp automatic, is informed by cognitive states informed by the body.
Affect is the general sense of feeling that you experience throughout each day. It is not emotion but a much simpler feeling with two features. The first is how pleasant or unpleasant you feel, which scientists call valence. . . . The second feature of affect is how calm or agitated you feel, which is called arousal. [0]
Simple pleasant and unpleasant feelings come from an ongoing process inside you called interoception. Interoception is your brain’s representation of all sensations from your internal organs and tissues, the hormones in your blood, and your immune system.
...[M]oment-to-moment interoception infuses us with affect, which we then use as evidence about the world. People like to say that seeing is believing, but affective realism demonstrates that believing is seeing.

> I ended up writing a small JavaScript function to maximize font size: it makes the text invisible (via CSS visibility: hidden), tries displaying the text at a very large size, and then tries successively smaller font sizes until it finds a size that lets all the text fit. It then makes the text visible again.
That would be a good application for dichotomic search if performance was ever a problem (I doubt it though).
More generally, having elements on a grid of different sizes should hopefully be much more easy once CSS masonry grid is available.

That is super cool! I might need to build one of those. My family needs a way to keep the fridge calendar up to date with our digital calendar.
for your family cal, check out TRMNL. can go on a fridge w/ magnets: https://usetrmnl.com (disclaimer, i'm the founder)
I made an eink rpi display for staying in touch with my parents, inspired by the poetry clock ( https://www.theverge.com/23669343/ai-clock-chatgpt-poems-rhy... ). My dad didn't like poetry clock, but he does like image gen. So we got a (color) Inky Impression 7.3 and hooked it up to an RPi. I made a basic telegram bot that you could send a verbal prompt to ("snowy day"). It would then ask which of your favorite artis…
That's fun. Although, from the article:
> There’s one other problem, though. It’s well known that AI language models like ChatGPT have a tendency to make up data (sometimes known as “hallucinations”), and it turns out that’s true even if you’re just telling the time. Roughly once every 15 minutes, says Webb, the clock will simply lie about the time just to make a certain rhyme work. “The fibbing is hilarious. Sometimes you can’t tell — it might say ‘one past two’ when it’s actually ‘two past one,’” he says. He says this will be fixable but, for now, is a fun quirk of the system. “Clockwork means you get precision drift; AI-work means you get hallucination drift.”

There was a study that suggested that the motor cortex can remember even if short term memory conversion was destroyed. If nothing else, myelinization counts as a form of memory. Strengthened by reuse. I would love to know if those warm feelings are stronger with individuals who remind you of someone you used to know. “This nurse reminds me of Aunt Sarah, who was nice to me when my dog died.” And so forth.
That study is an interesting suggestion that there might be a physiological basis for the explicit / implicit distinction in terms of memory. Makes sense in many ways that some kind of memory might be embedded in the motor cortex. I wonder if the same is true for emotional memories and midbrain structures, as hinted at in your last paragraph. I always find those non-obvious connections fascinating, like the disorders…
I have a relative with anterograde amnesia from a stroke, so that story got passed on to my father when it happened. 8 years ago perhaps?

if you think about it, we are incentivized to do this. no subscription fees means the more you ping our server, the lower our margin. but for now we're wrapping up fulfilling all pre-orders, scaling, etc typical new product issues.
even without BYOS (bring your own server) docs however, it's already possible to point TRMNL to your own stack if you 1) fork our OSS firmware + b) have some experience with e-ink.

They seem to have the api base url hardcoded in their firmware[1]. The repo seems to have pretty clear instructions for compiling and flashing modified firmware. From there, it's just a matter of writing a decent server to implement the calls documented in BYOD/S[2] and Private API.[3] [1]: https://github.com/usetrmnl/firmware/blob/e3db8c37990c2333ec...
