I tried to look up human wattage as a comparison and I'm very surprised that it lands around the same ballpark. Around 145W as a daily average and around 440W as a an approximate hourly average during exercise.

I thought current gen robots would be an order of magnitude less efficient. Maybe I'm misunderstanding something.

Electric motors are very energy efficient. I believe they are actually far more efficient on a per-joint movement basis, and the equivalence between us and them is largely due to inefficient locomotion.

Where we excel is energy storage. Far less weight, far higher density.

But how do you know if you can trust the docs if they are AI generated?
BobbyJo · 3 days ago
How do you know if you can trust then if they are human generated? Your trust the people. AI isn't going to jump and just generate docs, a person has to prompt it, and you should expect the person to proof read and correct it. If the person turns out to be untrustworthy, you stop trusting them.

But it is a pretty good signal of low quality.
BobbyJo · 3 days ago
A signal is something you use to discern something in lue of direct information. In the case of docs, just look at them and if they suck, or are good, it doesn't really matter where they came from. That being said, Ill take AI generated docs over no docs, and no docs is very common.

> already has an engine for building websites with Zig, but making sure that every Zig library has docs

Tbh, this sort of auto-generated docs from source code is not all that useful, since you get that same information right in the IDE via the language server.

The important documentation part that's currently missing is how everything is supposed to work together in the stdlib, not the 'micro-documentation' of what a single type or function does. And for this sort of information it's currently indeed better to look at example code (e.g. the stdlib's testing code).

IMHO it's way too early for this type of high-level documentation, since things change all the time in the stdlib. Putting much work into documenting concepts that are discarded again anyway doesn't make much sense.

Tests very often don't tell you the right way to use something, especially when you're talking about IO libraries. Examples themselves often don't even show the "correct" way, but rather just a way that will work in ideal circumstances.

I don't want to read ai slop comments. If you cant be bothered writing docs, I cant be bothered learning to use your library.

Just because and AI produced it doesn't mean it is slop.
BobbyJo commented on AWS CEO says using AI to replace junior staff is 'Dumbest thing I've ever heard'   theregister.com/2025/08/2... · Posted by u/JustExAWS

This is probably the right solution. It seems in reality nobody does this since it is expensive (more teachers, real attention to students, etc). Also if there is an explicit split there will be groups of people who "game" it (spend disproportional amount of time to "train" their kids vs actual natural talent - not sure if this is good or bad).

So, it feels to me ideally within the same classroom there should be a natural way to work on your own pace at your own level. Is it possible? Have no idea - seems not, again primarily because it requires a completely different skillset and attention from teachers.

This was the way all schools worked in my county in florida, at least from middle school on. Normal/Honors/AP split is what pretty much every highschool did at the time. You could even go to a local community college instead of HS classes.

I'm gonna add another perspective. I was placed, and excelled, in moderately advanced math courses from 3rd grade on. Mostly 'A's through 11th grade precalc (taken because of the one major hiccup, placing only in the second most rigorous track when I entered high school). I ended that year feeling pretty good, with a superior SAT score bagged, high hopes for National Merit, etc.

Then came senior year. AP Calculus was a sh/*tshow, because of a confluence of factors: dealing with parents divorcing, social isolation, dysphoria. I hit a wall, and got my only quarterly D, ever.

The, "if you get left behind, that's on you, because we're not holding up the bright kids," mentality was catastrophic for me - and also completely inapplicable, because I WAS one of the bright kids! I needed help, and focus. I retook the course in college and got the highest grade in the class, so I confirmed that I was not the problem; unfortunately, though, the damage had been done. I'd chosen a major in the humnities, and had only taken that course as an elective, to prove to myself that I could manage the subject. You would never know that I'd been on-track for a technical career.

So, I don't buy that America/Sweden/et al. are full of hopeless demi-students. I was deemed one, and it wasn't true, but the simple perception was devastating. I think there is a larger, overarching deficit of support for students, probably some combination of home life, class structure, and pedagogical incentives. If "no child left behind" is anathema in these circles, the "full speed ahead" approach is not much better.

Your one bad year doesn't invalidate the fact that it was good to allow you to run ahead of slower students the other 9 years. It wasn't catastrophic for you, as you say yourself you just retook the class in college and got a high grade. I honestly don't see how "I had a bad time at home for a year and did bad in school" could have worked out any better for you.

> So, I don't buy that America/Sweden/et al. are full of hopeless demi-students. I was deemed one.

A bad grade one year deemed you a hopeless demi student? By what metric? I had a similar school career (AP/IB with As and Bs) and got a D that should have been an F my senior year and it was fine.

BobbyJo commented on AI tooling must be disclosed for contributions   github.com/ghostty-org/gh... · Posted by u/freetonik

There's a lot of discussion about the ethics of AI disclosure going on here, but this maintainer is writing this from a place I recognize - community-driven, participatory development by people who enjoy programming, talking about it, and teaching each other how to do it.

Not every software project needs to attempt to maximize productivity. Not every software project is a business. Some are just created by people who enjoy programming. By hand. It's OK to set that as a culture. I guess I get it.

I don't mind AI tools, I use them judiciously, but sometimes I just want to do some coding - for me it's a genuinely relaxing and mentally satisfying activity to write some good code -, and I'm happy there's still others around me who do as well. Gardening context prompts and what not just isn't nearly as fun as just doing it, and not every project has to be economical. This one is yet another terminal emulator; it's not going to be the next unicorn. But I bet it's fun to hack on.

This project was literally born from a place of "because I want to".

I don't think you have a realistic view of how this will be used.

First, porn.

Second, artificial botting to make your game look active.

Third, hire a art developer in india, VPN them to your AI tool, fire them when the game is done.

You really should check your prescription rose colored glasses.

It's a very difficult balance to strike imo. People do take niceness and humor as signs that you're not quite as "professional". Of course, other people don't make this mistake, but we don't live in a vacuum - sometimes the jellybrains have control over our promotions.

The difficulty is why it requires intelligence to achieve. It is easy to be mean, and easy to be kind to your own detriment. Being kind while still thriving yourself takes thought.
