So they made a system by trying out thousands of combinations to find the one gives best result, but they don't understand what's actually going on inside.


I don't think 3D printing materials are suitable for lunchbox.


There are food safe materials, although you want to post process some to remove porousness that can harbour bacteria.


Right. And a lunchbox would have to be close to the worst-case scenario for an item where 3D printing would actually be used.


I don't think it's meant to be a literal bento, the page shows photos with bolts and markers.


I've also thought that - just rechecked and found a useful link https://formlabs.com/uk/blog/guide-to-food-safe-3d-printing/


there is a large selection of food safe filaments like TPU


This is a well-worn topic, but FDM has many potential issues that make food-safe printing significantly challenging.

It is alas not enough to use a food-safe filament; you need a food-safe extruder drive and nozzle, and almost certainly will need print post-processing to make the printed item physically food-safe.

The issue with a lunchbox is acute because it has potential contact with individual items of food for hours at a time, on a regular basis. It's the perfect setup for bacterial growth in the layer lines -- close to the worst-case scenario.

There would be ways to mitigate that (liners etc.) but arguably even a food-safe filament would need considerable vapour smoothing or coating.

Hard TPUs up at the Shore 75D range would be tough enough for the job but they would scuff up while cleaning, and are resistant to coatings etc.

(Side note being that 75D TPU is quite capricious to print.)


Have you printed with TPU? It's very porous.


Everything is porous when printed.


blowtorch or acetone bath etc can make some nice pieces

i mostly stick to petg for everyday stuff tho


If brain is just a transceiver, then it's unprovable.


I subscribe to this theory. In that case it's not necessarily unprovable though. We will eventually figure out how to make electronic devices resonate with the field just like our brain does.


Climate change is unavoidable. People should start moving to highland now.


Sea level rise from climate change is a fairly marginal issue in most places on the scale of a human lifetime. Famine from drought is a much bigger problem in the short term.


This is often said in the sense that “we shouldn’t try to stop it we should just adapt”

No one ever thinks of ports. Imagine rebuilding all port infrastructure every 5-10 years.

Move to highlands all you want but simply giving up is not likely to be cheaper.


We probably won't rebuild most of what is lost. People will largely have to make due with living in poverty for an indeterminate number of generations.


I'm covered, I live on a topological local maxima of 100 feet above the "major" local minima of "800ft" on essentually solid rock, assuming it doesn't become the next sahara, I should be able to collect plenty of rain water for personal needs and have methods to filter it. Currently have enough solar for off grid and backup generators as secondary. Hopefully well armed enough to stave off interlopers if it becomes that desperate. I doubt if my house would survive a tornado though, but should be covered from other natural disasters.


What happens if there is a drought in your area? How do you get water?


I covered that, I have 3000 gallons worth of water storage available and means to filter it. I hope to double it in the coming years. Perks of having 10 acres of land to do with as I wish. Some people have hobbies like classic cars, traveling the world, etc, mine is being prepared for climate change I guess? Not sure. It's something I've just been doing the past 10 years or so. There is a whole genre of websites on it if you dig. Not everyone is a right wing nut preparing for zombies :). I'm just anticipating reality. I assume if it got really bad due to climate change I'd have to leave, but mostly I'm covered on natural disasters in my area for the foreseeable future.


There is no reliable water on the highlands because it depends on micro local precipitation. The lower down you go, the more reliable your water supply becomes because of the larger catchment area. But the lower down you go, the more chances you will get flooded.

There are no good answers.


And did you do it?


I did. Northern Appalachian/Allegheny Plateau region. Lots of cheap real estate with low natural disaster risk.

Also a great region for small scale agriculture. Climate change might even help this region's arability.


I actually had sea level rise and radius from likely thermonuclear targets in mind when I bought my house.

I hadn't read The Science yet, so I believed The Propaganda. Now that I've read The Science (IPCC reports), it turns out sea levels are unlikely to rise more than 50cm, and definitely not 10+ meters like I was preparing for.


> radius from likely thermonuclear targets

which direction did you take it though? did you move to a place away from likely targets (which really, with as many nukes that are out there, what's not a target?), or did you move closer so that you'd be taken out in the first wave and spared the life of misery after? my dad used to say that one of the deciding factors where he chose to build the house I grew up in was based on the latter.


I moved away from the most likely target, enough that I would be likely to survive a 400 kt nuke.


If it's an actual full tilt global thermonuclear war with everyone using all of their arsenal, I'm not really sure I would want to live in that post-apocalyptic world. Now if it's just a couple of bombs in major metro areas, that's a different situation.


But how closed are you to post-nuclear logistical chains that would keep you fed and healthy?


It really depends on the scale of a conflict. What I might be likely to survive would be something like a terrorist attack or some minor nation (like North Korea) going crazy.

I don't think there is any public setup in my country that would allow large parts of the population to survive a global collapse in international trade combined with a nuclear winter that could last years.

To survive something like that would require a full prepper setup. Like a cottage deep in the wilderness, with food storage for a couple of years, water for at least several weeks, lots of ammo for the rifle and all sorts of tools, seeds, etc required to start farming when the weather normalizes.

That would be out of scope for me, as it would take up a large part of my life.

Selecting a location to survive a minor attack is as easy as consider the view or access to infrastructure when buying a house, though.


I mean, you and I probably can, but the majority of folks can't.


For 'low latency' in eInk, it's about the same time to turn over a page.


LLMs are still toys, no one should treat them seriously. Apparently, the bubble is too massive now.


We have businesses getting real value from these toys. Maybe you have not been in the right circles to experience this?


Of course you can get value from toy business, but toys are toys.


Used toys to write a working machine vision project over last 2 days.

Key word: working

The bubble is real on both sides. Models have limitations... However, they are not toys. They are powerful tools. I used 3 different SotA models for that project. The time saved is hard to even measure. It's big.


> The time saved is hard to even measure. It's big.

You are aware that this is an obvious contradiction, right? Big times savings are not hard to measure.


Right... With precision...

Furthermore... big mountains are easier to weigh v small individual atoms? I think it's a little more complicated than big is easy to measure...

I care little about the precision... I've got other priorities. It's the same as the time the internet saves me... Big. It's obvious.

I stand by my statement. It's hard to measure...


Must be a pretty cool toy; it constantly 10X’s my productivity.


You said it mate. I feel bad for folks who turn away from this technology. If they persist... They will be so confused why they get repeatedly lapped.

I wrote a working machine vision project in 2 days with these toys. Key word: working... Not hallucinated. Actually working. Very useful.


My daughter berated me for using AI (the sentiment among youth is pretty negative, and it is easy to understand why), but I simply responded, "if I don't my peers still will, then we'll be living on the street." And it's true, I've 10x'd my real productivity as a scientist (for example, using llms to help me code one off scripts for data munging, automating our new preprocessing pipelines, etc, quickly generating bullet points for slides).

The trick though is learning how to prompt, and developing the sense that the LLM is stuck with the current prompt and needs another perspective. Funnily enough, the least amount of luck I've had is getting the LLM to write precisely enough for science (yay I still have a job), even without the confabulation, the nuance is lacking...that it's almost always faster for me to write it myself.


> My daughter berated me for using AI (the sentiment among youth is pretty negative, and it is easy to understand why)

I can’t relate. Currently in university. Everyone is thankful to God ChatGPT exists. I’d think it must be a joke, or your daughter somehow managed to live in a social circle which doesn’t yet adopted chatbots for school purposes.


I just don't understand why AI is so polarising on a technology website.

OpenAI have even added a feature to make the completions from GPT near-deterministic (by specifying a seed). It seems that no matter what AI companies do, there will be a vocal minority shouting that it's worthless.


It is baffling where the polarization comes in.

The idea that we argue about safety... Seems reasonable to me.

The argument about its usefulness or capability at all? I dunno... That slider bar sure is in a wierd spot... I feel ya.


Without details that's a meaningless stat, I remember some pytorch machine vision tutorials promising they'll only take like an hour, including training and also gives a working project at the end.


It's staggering to me that people on Hacker News are actually downvoting people saying how AI is boosting productivity or levering business or engineering or finance. The denial, cynicism and sheer wilful ignorance is actually depressing. I get that not everyone is working directly with AI/ML but I honestly expected better on a website about technology.

People are deliberately self selecting themselves out of the next industrial revolution. It's Darwin Awards for SWE careers. It's making me ranty.


Yes, you can make eInk refresh faster, but with ghosting and limited grayscale level. eInk hasn't advanced much since its advent, and no sign it will, as it's controlled by one company.


> eInk hasn't advanced much since its advent

Yes, it has. Even purely from the consumer facing side: the latest panels are far better in grayscale depth, sharpness and refresh rate (and their controller still kind of suck). Not to mention colour e-ink panels in consumer products seeing rapid improvements gen over gen.

> and no sign it will, as it's controlled by one company.

That's less true today, and there are multiple implementations of this idea that are being commercialised.

Though, sadly, e-ink the company bought one of them...


How much can you get from incubator or VC ... for free?


I know swift has poor performance, but not expect they did it purposely.


The whole site feels AI generated.


Nah, it feels like one of the low-quality content farms that were used to train LLMs. Even GPT-3 wouldn't have inserted a sentence like this one:

> The answer, as CleanTechnica readers who are all above average know, is the flaw in the capitalist model known as “untaxed externalities.”


Back in my day, this was called "blog spam."
