I wonder if you could use this to generate the fractal terrain by the ocean like in Sydney. We already have "artificial reefs". We have built beauty in the build environment (architecture), some in the natural environment (gardens, forests), but comparatively less when it comes to the ocean.


They are doing this now actually for plant breeding! "Engineering crop flower morphology facilitates robotization of cross-pollination and speed breeding" covers one example by breeding flowers to be more easily pickable by robotics.

I posted a thread here in 2019 for anyone curious on the technical walkthrough for setting one of these up (+ HN discussions) [1].

This is freakin' amazing! Such a glorious hack.

It'd be fun to build a pure CLI-based OS around this. Imagine opening apps by running `/www/github.com`


The challenge is that you might only need 6 hops to find that person you’re looking for (on average).


Yes but that would be about finding a Pete when you only know Felix - you knew every link in the chain already, including Pete.

I'm not saying don't be glad you met Felix because it led to your house, just that I don't think it's a case of 6DoS.


It seems we disagree on 6dos. I think it's a useful concept to anchor on, since you can predict the structure of your domain (social networks, renting) based on the size of the network, and then optimize your routing so you get to a certain node (a nice house to live) quickly. Or even in my case - realising there is a path in the first place.

I hope this translates more clearly into engineering terms. The original audience of this post was non-technical.


> It's trivial to work backwards through your life and reshape everything as a series of coincidences that got you to where you are.

What if you worked forwards based on this idea of coincidence engineering?


Well, now you've got Foundation.


Haha, well you're right. The point of writing is to think. I never said it was going to be a scientific theory - and really, life is too complex a landscape to build a falsifiable theory anyways. We can still discuss anecdotes though.


Thank you for the linkout, I'll put it on my reading list.


Haha congratulations! You got it.


Although I would highlight - there is additional high risk now if the sensor becomes faulty, in which case, more insulin could be delivered for incorrect levels while you sleeping, etc.


I don't know if insulin pumps are used while sleeping. After all, there's a needle inserted in your skin.

You wake up from hypoglycemia, long before there is more trouble. And the sensor doesn't post glucose levels for example if it gets detached.


Insulin pumps (and their cannula; not a "needle") are installed 24/7. They can be "suspended" and the insulin delivery hose unhooked, but they are generally there, and active, at all times. Likewise, a CGM (continuous glucose monitor) will provide, as the name says, continuous monitoring. Both use adhesives to keep them attached and generally remain so, even while sleeping.

Hypoglycemia also may not lead to "waking". After all, a diabetic coma may result from low blood glucose, depending on how quickly it crashes.

Source: my girlfriend is Type 1.


Diabetic coma is caused by prolonged hyperglycemia (too much blood sugar) and diabetic ketoacidosis. Many diabetic patients go through months of hyperglycemia and even ketosis before they even know that they have diabetes.

Hypoglycemia in healthy adults mainly results from not eating and develops rather slowly. It's hard to recognize at first, but it will get a lot more obvious before it gets serious.

Hypoglycemia in diabetic patients is more often caused by too much insulin delivered at mealtime and this happens more quickly. Patients can become unconscious before they notice the problem, but usually they recover even without treatment. The goal of diabetes treatment is to avoid this hypoglycemia, also because the body reacts with increased glycogenesis leading to an overshoot of blood sugar.

There are sometimes suicide attempts with insulin. This rarely succeeds, it can result in brain damage, but mostly the patients wake up sometime later.

At night an insulin pump would not need to deliver that much insulin. There are also very long-acting types of insulin, which may be preferable to the short-term insulin in the pump to achieve the "baseline" during the fasting period. Or not. That's a strategy question, I guess. I had type 2 for a short time, and I used long-term and short-term insulin at meal times, with the finger-pricking type of measurement.

I don't think insulin pumps would carry enough insulin or are able to deliver enough.

My point is that there is a relatively large margin of error for any algorithm or software before serious harm occurs, and that the continuous monitoring and delivery is already superior in achieving good glucose curves, regardless if the control loop is manual or automatic.

I've read that continuous sensors help patients to have fewer incidents of hypoglycemia.


Haha, I'm the OP, I use the insulin pump ;)

> You wake up from hypoglycemia, long before there is more trouble

And this is one of the main styles of diabetic death - not waking up (diabetic comatose).

> And the sensor doesn't post glucose levels for example if it gets detached.

I was more referring to the circumstance when you're lying on your sensor in a funny way, and it begins reporting incorrect levels.


You can loose consciousness from hypoglycemia, but normally the body will do everything it can, even autophaging your heart muscle proteins to bring it back up. Unless you have been fasting for a really long time, it will just release glucose from glycogen reserves and you recover quickly.

The diabetic coma thing is the opposite spectrum when the blood sugar is extremely high but the cell metabolism has to run on ketogenic fuel because it gets no glucose. Which leads to ketoacidosis, which can ultimately lead to a coma.
