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”.

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.

You mean xAI?

I am joking

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”.

I would probably do a one-time purchase but I don’t do subscriptions.

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A pdf is just a digital version of paper, and since paper is obsolete, the pdf is probably a bit archaic for somebody who has no intention of printing it.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.

2.1 ppt (parts per trillion)

I learned to type from instant messaging: ICQ and AIM. I know I did Mavis Beacon too but that was the practice that solidified it.

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.

Lol screenshot, pdf, what’s the difference really?

I believe the most computer proficient people were born between 1975 and 1995. Before that and they were too old to figure it out without a lot of effort. After that they grew up with touch screens and it’s all just magic. Right in the middle we were able to grow along with advancements in computing.

I was teaching a class with mostly students born after 2000. One of them had never used a computer with a keyboard and mouse. Never used folders and files. Kind of blew me away.

It’s easy to restrict access. It’s hard to restrict access while letting search engines index your content, driving traffic. Maybe a local paper simply gets most of its traffic from the first paragraph summary, or local subscribers, so they don’t need to let Google index the whole article.

Well at least all the international visitors wouldn’t be disappointed with the dry cliffs.

There’s already a dam at Hetch Hetchy. All they need now is some pumps and pipes to bring more tourists to Yosemite Valley in Summer.

Brush up against one and you’re assaulted - it’s like skunk spray in the plant kingdom.

For me peanut butter is not as bad as dry roasted peanuts. For some reason before they’re pulverized, it smells like cigarette smoke to me.

Somebody has to make the call. There was this dinosaur book for kids in a little free library. It didn’t even have an author or publisher, because it was AI garbage. Full of misspellings, etc. I contemplated throwing it in the trash because I don’t think it should exist. But for some reason I had trouble deciding that for others.

Digitize and delete? Scan straight to OCR and dump the books. One hard drive can store a lot of books.
