toisanji··on Memory decline after menopause linked to loss of estrogen production in brain
Any remedies to reverse this?
toisanji··on Image-blaster: Creates 3D environments, SFX, and meshes from a single image
I see it used worldlabs, i’ve tested it quite a bit and no results were not really that usable, it hallucinated so many parts outside of the wall that made no sense. He will be fine if hallucinated and it made sense but if it doesn’t make sense, I’m not sure what the point of inputting a single image is. I’ve actually found better luck using gpt image 2 instead.

toisanji··on Blood test boosts Alzheimer's diagnosis accuracy to 94.5%, clinical study shows
Great but the big problem is how to actively treat it. Sleep is a huge factor and that’s a problem for us insomniacs :(
toisanji··on Pebble Production: February Update
Do the pebbles have the same functionality as the Index ring? As in we can record notes with it?

toisanji··on Pebble Index 01 – External memory for your brain
This sounds kind of cool, but I'm more worried about the e-waste. A device that is cheap, will get "recycled", and sounds cool, will get a tiny amount of use after the initial wow factor wears off or doesn't fit the needs, then gets thrown away or lost. And is this feature in the new repebble watches? I would rather have it there with a bigger battery.

Ok would like to learn more about what you have been building, can we talk? I have thought of similar ideas.
toisanji··on Spatial intelligence is AI’s next frontier
There is research showing that the grid cells also represent abstract reasoning: https://pmc.ncbi.nlm.nih.gov/articles/PMC5248972/

Deep Mind also did a paper with grid cells a while ago: https://deepmind.google/blog/navigating-with-grid-like-repre...

toisanji··on Spatial intelligence is AI’s next frontier
From reading that, I'm not quite sure if they have anything figured out. I actually agree, but her notes are mostly fluff with no real info in there and I do wonder if they have anything figured out besides "collect spatial data" like imagenet.

There are actually a lot of people trying to figure out spatial intelligence, but those groups are usually in neuroscience or computational neuroscience. Here is a summary paper I wrote discussing how the entorhinal cortex, grid cells, and coordinate transformation may be the key: https://arxiv.org/abs/2210.12068 All animals are able to transform coordinates in real time to navigate their world and humans have the most coordinate representations of any known living animal. I believe human level intelligence is knowing when and how to transform these coordinate systems to extract useful information. I wrote this before the huge LLM explosion and I still personally believe it is the path forward.

toisanji··on Apple Watch Ultra 3
ON battery life, I would love some kind of dumb phone/ ultra low power mode that we can set when we just want watch mode at certain times and nothing else. I imagine that would give us a week of battery.

toisanji··on Offline.kids – Screen-free activities for kids
Nice work on offline.kids and kudos for tackling screen-free play. I've been playing in a similar space. If you want something complementary for the inevitable “but why?” moments, you might like StudyTurtle Ask (https://studyturtle.com/ask). It’s a free, no-signup AI Q&A tuned for 3–9 year-olds with:

Strict age calibration (matching phrasing and examples to each developmental level)

Concrete analogies (“volcanoes are like shaken soda bottles”) and kitchen-table experiments you can actually do

toisanji··on Show HN: App to Help Parents Explain Anything to Kids–and Parenting Questions
It is a concern I have, but it's a concern with every new technology. The user, or in this case the family are the ones that need to decide how they will wield the technology.

The way I think about this tool is that it is way to spark and test our curiosity. Is the child really interested in space or just randomly asking questions. Tools like this can help you as parent determine this faster.

For family tools like these I would want parents to know everything the child is asking about.

toisanji··on Study mode
Every technology can be good or bad to an individual depending on how they use it. It is up to the user to decide how they will use the tool. For people who are really looking to learn a topic and understand in detail, then I think it can really help them to grasp the concepts.

Thanks so much, I will add these sections as well, hopefully this can replace some of what you do with your child!

Please let me know if you have other feedback!

toisanji··on Launch HN: Hyprnote (YC S25) – An open-source AI meeting notetaker
is this a known pattern, I did a basic tauri app, but not sure what to do with mobile yet...
toisanji··on Study mode
I truly believe AI will change all of education for the better, but of course it can also hinder learning if used improperly. Those who want to genuinely learn will learn while those looking for shortcuts will cause more harm to themselves. I just did a show HN today about something semi related.

I made A deep research assistant for families. Children can ask questions to explain difficult concepts and for parents to ask how to deal with any parenting situation. For example a 4 year old may ask “why does the plate break when it falls?”

I've done it a few time, not sure if it worked for me, but if it really works, I would love to feel those effects. Maybe I need to do it more?

toisanji··on Obituary for Cyc
I think there could be a next generation cyc. Current llms have too many mistakes and grounding it with an AI ontology could be really interesting. I wrote more about it here: https://blog.jtoy.net/understanding-cyc-the-ai-database/
