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.
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.)
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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...
