Oh, I realized I answered how we set it up, but maybe not what we do. It's just during regular library time, a parent volunteer presents/reviews a concept (the teachers tell us what they've been working on) and has an activity. Depending on the grade level, it might be playing with batteries, switches and bulbs, bringing in nature to look at under the microscope, building a motorized vehicle with LittleBits, or tryin…

This is awesome - thanks f you would not mind I would love to try and replicate it at my kids school(s!) - can I contact you?

Sure - link in profile. If you can't tell, I'm trying to figure it out as I go.

How old are your kids? My eldest is 5, and this is starting to be more and more top of mind. I felt like earlier on that it wasn't worth thinking much about it because it was too hard to predict what the issues would be as they became relevant to her. I think this turned out to be right, because if I'd thought about this a bunch a few years ago, I wouldn't have included generative AI in my thinking at all.

Less than a year old, but I have been thinking about the issue proactively and there are things you can do for them even at this age. For instance, I set my son up with a Proton email account on the family domain name before we left the hospital (see my reply to sibling comment for reasons why).

Well, I understand the new-parent exuberance, but I'd just say that I think you may lose the energy for that kind of thing over time :) Sure, you can make an email address for a one year old, but it is not going to be useful for an extremely long time, and there is a non-zero chance it will never be useful at all, because email will no longer be a useful thing by the time it would have been. Seems like premature optimization!

But of course there's also nothing wrong with thinking about and doing this kind of stuff even if it never turns out to be very useful, if you enjoy it, that's enough :)

Low-plastic living. I read a book by the world's first zero-waste restaurant, Silo. The book got me thinking about how different our lives would be if oil were expensive. "Pretend oil is really expensive" is a good proxy for doing things that are "eco-friendly." Since reading the book, I've tried to eliminate single-use plastic from most of my life. It's incredibly hard. Everything from my socks to my vegetable packa…

How do you find products that don't have a lot of plastic waste in their manufacturing and supply chain?

It's not that a beginner cannot put 20kg on their back or chest. It's that a beginner does not know how to safely put that 20kg on their back or chest. Especially the chest. Also some exercises like the deadlift can't be done with an empty bar. Stronglifts would ask you to start with 95lbs which is too much. To me your comment is toxic and reeks of a sense of superiority and elitism from your own experience. You labe…

> Please no. The beginner does not discover places where the form needs improvement. The beginner simply fails to lift after increasing the weight. The beginner injures themselves when they thought they could lift but they did not. This assertion is contradicted by the hundreds of thousands of people (myself included) who have progressed beyond the beginner stage after starting out with the 20kg bar and without ever…

Wow, weight lifting is seriously ‘gate-kept’. GP needs to chill, he’s being elitist, and forgetting PTs are super expensive. I followed Stronglifts to 110kg, and just started again after 4 years. It’s fun. It’s easy. You focus on few, simple exercises, so form is easy to do well if you try.

I am passionate about AI in education. Economies die because of underutilized or wasted resources. Our educations system is horrible at wasting everyone's time right now. Source: I've been teaching since the 1990's and learning in school since the late 1970's or 1980. AI can fix most of that. Example: It has been many years since I looked a C code and I never really understood much about the Linux Kernel, even back w…

Problem with learning from AI is that you don't know if it's telling you b/s or not.

Reminds me when my 6th grade history teacher taught from the old testament. Of course, with standardization maybe that doesn't happen much anymore.

Powerlifting. Solitary and meditative if you want it to be; social and uplifting if you don't. It's healthy in a variety of ways (including bone density; physical activity; higher BMR and glucose metabolism; improved cardiovascular function). Also being strong is useful surprisingly often. Unlike many things in life, your progress is almost entirely dependent on your consistency and the effort invested, with the exce…

> Unlike many things in life, your progress is almost entirely dependent on your consistency and the effort invested This really resonates with me. Not powerlifting myself, but I have a strength training routine at the gym with the goal of improving my right knee pain. I have to take things very slow (increase by 1 rep each session, up the weight every ~2 weeks by the smallest possible increment) but looking at my gr…

I really empathize and am glad you pointed this out. I needed specific exercises to fix my abductor/flat left foot, which were wrecking my hip.

Body progress is slow, but it feels wonderful to have something you can control, master, and is directly rewarding.

Kudos for sticking with it :) Good luck and keep building protections around that knee.

ChatGPT makes very good training plans if you know what you want. Like a 4 day split with XYZ available machines. Not for beginners, but very good if you want to think a little bit less which exercises you take for the next 4-6 weeks.

There are plenty of better researched sources for training plans. This seems like an area where their inaccuracy can cause direct, physical problems.

right now, I'm trying to figure out if fabricated steel with the right design can accomplish a functional analog of what cast iron can. the objective is to leverage flat pack laser cut pieces instead of castings.

it can certainly be equally rigid if that's what you're after; they have very close to the same young's modulus. thermal stability and vibration absorption is more challenging i think castings often come out closer to net shape than weldments and thus need less final machining, but i could have that backwards. they both shrink as they cool, but weldments don't need draft

Weldments have less shrinkage/distortion than castings, but not none. In machine tool applications, it's the vibration damping that everyone cares about, but my ultimate objective will be to find out whether it matters if you engineer in sufficient rigidity. Theoretically, for the vibrations to be an issue you'd need to get some resonance, so if you tune that out in the design spec it should be something that can be ignored. Nothing like empirical testing, though.

yes, I learned my lessons the hard way.

I don't know any bodyweight fitness myths and I do not exercise with my bodyweight alone.

The amount of critical thought I have put into the things I have not elaborated on is insane.

I cannot back up my statements with data. Partially due to laziness, partially because the data does not exist yet and mostly because athletes lie too much.

I fucking love progressive resistance training.
