I’m no fan of exercise. But as I imminently approach 40, I’m feeling and seeing its value more and more. The purpose of fitness is not longevity - it is independence and quality of life. Just assume you’re going to live to age 90 either way. Look around at some 80 year olds. Breathing machines, walkers, bed ridden… how do you want to spend your years? Years! Your body will become a torture prison unless you tend to it. Dying is the least of my concerns.
Maple syrup is tree blood. Kind like tree vampirism.
I don’t think wood smells like food. But I wonder… apparently termites have a bunch of gut bacteria to digest wood. Maybe if you eat raw termites and bark beetles, you can then eat some sawdust. If you continue the process eventually you may be able to eat wood or paper with your own gut biome. Maybe start with a termite, sawdust, and banana smoothie and move up from there. Best of luck.
Well anyone can 3D print something, but it’s the modeling of a printable object that is your skill. However modeling and designing are two different things.
If I had your equipment and skills right now I would start printing bathtub jet plugs. Convert a jetted tub into a non-jetted. Probably only a few different brands and designs to cover.
Aside from that, I’d get into mold making. You can 3d print a mold, or even a mold of a mold. Or a mold of a mold of a mold. Then you can cast objects in metal or ceramic, or silicone or even plastic (haha) or other materials that can be a liquid. Way more interesting than plastic shapes. Plus molds can be used many times.
As far as the business goes? No idea. Start by making useful objects that people want to buy. But that’s kind of a different skill of “inventor”.
I was just thinking about this. Love these videos. Cooling of a solar panel is a good application, as long as it gets cold enough for long enough to re-solidify at night.
An alcohol/NaCl solution with a stabilizer can make an ice pack that freezes colder than water. That could be used to keep ice cream frozen in an ice chest.
It would be cool to have recipes for a few different temperatures. There’s a German company Qool Products that sells PCM temperature elements (ice packs), at a variety of temperatures, to store ice cream up to red wine/cellar temp in their ice chest. With some trial and error I guess we could now make our own!
I’d really like if there was a high end router and switch without WiFi. I already have all my wireless handled by 3 access points. Is there a high end router/switch with 4 ports?
There are plenty of protected lanes in my city, but they just hide bicycles behind parked cars, making it less safe at every intersection.
The only way I can think that might work better would be to convert a 3-lane road (with suicide/turn lane in center), into a 2-lane road. The center lane gets converted into a two-way bicycle road - raised up like a sidewalk with curved curb. No left turns allowed for cars, only right turns. This way bicycles are visible and protected.
Yeah it’s typically not used for dosages, rather it’s for concentrations in solution. However strictly speaking the grams cancel in the units of ng/kg and you are left with ppt. I think of ppm and ppt as very small percentages anyway. As per cent means part per one hundred. Can’t use “permille” because it means part per thousand but sounds like part per million.
In the case of a lethal dose, I think it would be fine to say, “it’s lethal at a rate of 2 trillionths of body mass”.
It’s possible to make a rasterized pdf - that would just be an image with specs for printing. I think teachers need to specify their expectations. Submit a plain text file? Submit a markdown document? Submit a Word doc? Is hand-written okay? What about a type-writer?
A pdf is just a digital version of paper, and since paper is obsolete, the pdf is probably a bit archaic for somebody who has no intention of printing it.
Piwigo is more like a shared gallery. Users create album/folders and upload individual photos, which other users can access. Piwigo has poor support for videos and no support for Live Photos.
Photoprism has only a single user for the free tier. It supports Live Photos and videos, and individual photo uploads. It does facial recognition tagging.
Immich supports video/Live Photos, facial recognition, and has multiple users, but it expects a full backup/synchronization (not individual photos). Sharing between users is manual, not automatic or permissions-based like Piwigo. Each user has access only to their own backups or shared albums.
In summary, I think Piwigo is the simplest to set up and use, but it doesn’t do much beyond photos - it’s a simple shared gallery. Photoprism is good and stable, but you have to pay a subscription for multiple user accounts. Immich is rapidly developing, which means things will break, but also it has the most features. My only issue with Immich is that I don’t want to use it as a backup - only as a “best of” shared gallery. While it’s possible with Immich, I would have to maintain an Immich album on my phone, and sync only that, and I would have to set up shares with other users manually.
Hopefully my rough estimate of 1995 was not too exclusive. I’m sure there’s not a hard cutoff, and the same goes for pre-1975. But being right in the middle of that range, it was pretty cool to use the full spectrum of PCs, and all the game consoles, and see the internet bloom and explode and decay.
I would be an inventor. I would be an explorer. I would be a teacher. I would be an artist. I would be a musician. I would be an entertainer. I would be a builder.
