maxlin··on Dirty Optimization Secrets (C for Playdate)
Obviously you picked a part that is the most expensive part of it by far, and a clone could just have a little bit smaller screen, even with the same resolution, to case for that, and the efficient price would never go beyond 50$ in any case. What I said about the devkits I've developed for is 100% true. The price is ~30$ with the screen, SoC, microphones, etc etc ALL peripherals, packaging, actually good documentation including datasheets and multiple example projects for TWO whole different ecosystems.

Nintendo's economies of scale is irrelevant here as A. They obviously have enormous markup compared to hardware price, because they can, and B. Those waveshare devkits aren't built with insane numbers, but they manage to keep their prices down very well.

These are just some of the examples I was talking about https://www.waveshare.com/esp32-touch-lcd-3.5.htm https://www.waveshare.com/esp32-s3-touch-lcd-3.5.htm?sku=309... https://www.waveshare.com/esp32-s3-touch-amoled-2.06.htm?sku...

To put nails down the coffin of the argument about "economies of scale" here, just check how many alternative devkits they have. I'm sure that some of these have barely sold to triple digits. But the quality has been good for all I've seen from them https://www.waveshare.com/catalogsearch/result/?q=touch+esp3...

And for the "retro emulation" hardware that goes way beyond in specs but stays at ~50$: https://anbernic.com/products/rg35xx

Panic has had their fun. Time to commoditize the ecosystem.

maxlin··on Nitter: Update Oct 10th seeking funding and legal help
Most normal people that have a noticeable internet presence are there, as are those that would like to avoid places like Reddit, Truth Social or BlueSky which either have been founded as, or have became tribal drum houses.

These days, I feel like it might even be better than HN, due to both HN decaying a bit (it's still strong) and X getting better, especially due to a better fitting algorithm that gets me all relevant industry stuff while not having massive deadspots.

maxlin··on Triple-A Minesweeper
Funniest is, you can hit every single mine with no drawbacks.

I feel like there's some reference to the recent Wolverine game and it's unfailable driving sequences in that ...

maxlin··on Musk, the Movie
>Peak extinctionist talk is to pretend we can go see what's beyond the mountains, especially without solving all our cave problems first, as we can only ever launch such a lofty expedition from the cave.

>Also, going past the mountains is a pipe dream for people that know more about children's tales than _actually_ going from the cave to the nearby shore.

maxlin··on Musk, the Movie
I already like him for his previous, immense technological achievements. Go preach your ignorant hate somewhere else in the cave you live in.
maxlin··on Dirty Optimization Secrets (C for Playdate)
Your math is off ~10x. The devkits I've developed for are literally 20-30$, both in 3.5 inch screen format, or smartwatch format, with a case, touchscreen, buttons, battery, realtime OS, RTC, wifi, tons of GPIO's etc. Only hardware things playdate has on top is marginally higher build quality, the swivel (that most games don't use) 10-20MB more RAM. Their decision to have a greyscale screen also saves them money, instead of a common full color one like those 30$ devkits have.

So it is beyond obvious that Playdate's price does not even closely match their bill of materials.

Even if you went up in power to a full Linux machine with 1GB+ of ram, there are obvious examples of devices like that like the RG3588 class. I have one, and it works nicely as a linux box running any software one can get running on aarch64 linux. Mine is relatively fancy and with postage cost me ~100$, but you can get a more "basic" one that is still way beyond Playdate on a hardware level, for about 40$.

What playdate has is a walled garden. I don't like walled gardens. Especially this far from release.

You comparing to Nintendo's first-party joycon pricing, I'm not sure you understand how deep walled gardens can be.

maxlin··on I asked Claude build a physically accurate O'Neill cylinder you can walk around
I played Orbiter near its release - this is quite far from my intention with its focus on spacecraft and generally a low detail level.

My intention would be a game simulating, at least on a surface level, life inside an O'Neill cylinder, you being an individual doing things there that requires you to move around from the edge of the "world" to another continously, like delivering packages and such.

maxlin··on Dirty Optimization Secrets (C for Playdate)
I just wish someone released a clone. The "computer" is worth like 5$. I've enjoyed programming and porting my 3D game engine to 20$ ESP32 devkits among others, and am looking for more "crazy" platforms. But I don't even want to touch playdate due to its pricing stance, even though my office has an unused one in the store room.
maxlin··on I asked Claude build a physically accurate O'Neill cylinder you can walk around
I've had an idea to build something similar - or more specifically, a game in this form, since I saw Eric Bruneton's Rendezvous With Rama video, now about 15 years ago.

Never did hand code it, even though I gained a lot of the skills and work in gamedev. This makes me feel time is running out to implement it with some of the unique twists I had in mind that become apparent with something like this ...

Nope. That variable name could mean anything

this is just incredibly metal. Kinda stupid but kilometers above the bottom requirement for rule of cool.
maxlin··on Git 3.0's upcoming SHA-256 default will be a costly mistake
oof. I can only hope that as many as possible git clients/wrappers that people actually use stick with SHA-1. Solving issues related to that not having happened sounds like the least meaningful work one could be doing...
maxlin··on Guitar amp and effects pedal built on the Waveshare ESP32-S3-Touch-AMOLED-2.06
This devkit is awesome. I ported my game engine to it (which was already running on ESP32 so it was relatively easy) and actually use it as my everyday watch. Boots a 3D scene authored in Unity in about one second from power off. BMS keeps power to the RTC so it works as an useful clock, planning to add more features later.

Battery lasts for weeks with this cold boot mode too

maxlin··on Musk, the Movie
Yeah. Peak exctinctionist talk is to plainly just state we're never colonizing mars, lets instead hate on those that put immense effort to trying.

maxlin··on Japan moves to tighten rules for foreigners
I can only wish self-destructive western countries, including my own, would come to their senses and do similar things, especially the "retroactively" part!

Japan is a crown jewel how to handle these things, and proof it works.

maxlin··on Japan moves to tighten rules for foreigners
It's hardly insane, it's exactly the kind of rule all immigration should have. On side of the host country, to benefit all.

maxlin··on What even is an OS now?
A few lines before the reveal I thought of this a a product sold by business, then right after resuming reading again felt the old "ahh, missed the chance again" when you laid out you're already planning it...

But really, a platform that allows one to do all levels off apps in this way where one can cleanly reset their side effects and effect on the system, and the app is exposed just as an icon, not a folder of source files, could already be possible and could lower the bar of starting vibe coding to the bottom

maxlin··on Too AI; Didn't Read
What I mostly find issue is with people pushing incorrect, buggy, and low skill human work when AI would do the work better. It's sad to see oldschool pros clutching to their pearls; These days I often find myself trying to push them to do something that AI _can't_ do as well, instead of forcing a comparison.

Care about people but always through caring about the product and making people capable of earning their dignity.

>Literally no one is saying it’s impossible

You have the entirely wrong impression of people here. TONS of people are saying exactly that, and trying to disqualify the whole debate.

>likely for years to come

Starship is putting its first business payload to orbit in two days. The craft represents making mass to orbit magnitude(s) cheaper. Read the text on your side mirrors.

>any of Musk’s promises on time

I find this argument so frivolous. Ok, so they've made what was considered impossible, _late_ on a few occasions? And they visibly iterate, showing failure, as if it makes them somehow worse? It does kind of sound like you are not the engineering type, or at least don't work with actual hard problems.

The smartest people are still geniuses and the smartest even if they're late, while no one else is ahead of them.

maxlin··on Google’s Project Suncatcher to put ML infrastructure in space
Don't you think it's a _bit_ ignorant thinking the engineers at now several companies known for their genius didn't think of it? There's a meme for this kind of armchair drive-by commenting.

And the preliminary design shapes aren't unknown. They just have huge ass solar panels and radiators. Plenty of space in ... space.

maxlin··on Google’s Project Suncatcher to put ML infrastructure in space
Intentional Kessler syndrome would be such an escalation that even Starshield would be wiped out then, that's quite low in the "def-cons" ...

In any case, this is mostly for peacetime / civilian usage. Obviously military datacenters are and will be as secure as possible. Remember ARPANET was foundational for the internet.

maxlin··on Toyota is taking the Corolla electric
Corolla is supposed to be the cheap one. But this concept looks way too flashy and the prices seem quite "meh" for affordability.

What a missed opportunity.

maxlin··on Google’s Project Suncatcher to put ML infrastructure in space
Some people, claiming to be the authority on laws of physics. While people actually doing this are obviously more credentialed and talented than said internet fools.

It's getting quite tiresome.

You can't ask any of those direct questions in natural language. They are either rigid or uninteractive
maxlin··on Google’s Project Suncatcher to put ML infrastructure in space
From who? The crack addicts in space trying to steal copper?

The actual rack part is small, even if the solar panels and radiators are big. If this truly was super dangerous, ISS wouldn't be safe. And it's never hit mission-degrading issues due to micrometeoroids.

maxlin··on Google’s Project Suncatcher to put ML infrastructure in space
No western company, no. That's why I can only hope SpaceX can get thru more red tape faster, and future administrations don't try to slow them down.

Even while current administration is kind of positive towards them, they are still even now just having to wait for no good reason for a FAA go-ahead. These kinds of stalls don't really exist in China.

maxlin··on Google’s Project Suncatcher to put ML infrastructure in space
While a bit tin foil hat-y, this is an interesting (conspiracy) theory, even while space datacenters aren't as impractical as some people try to make them to be.
maxlin··on Google’s Project Suncatcher to put ML infrastructure in space
This. China's copying SpaceX's homework and the public/private system towards that is operating so efficiently, if SpaceX lets off the gas, US is going to fall behind off the next long term gold rushes like asteroid mining, and said space datacenters.
