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!

You mean xAI?

I am joking

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A pdf is just a digital version of paper, and since paper is obsolete, the pdf is probably a bit archaic for somebody who has no intention of printing it.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

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.

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.

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.

I hate when a restart fixes it. It means it will never be fixed.

Just ban plastic surgery from the contestants.

Sound and light don’t propagate well through changes in media. The reason rainbows exist is because light does not travel in a straight line through drops of water, across the full spectrum. Radar is used to sense how hard it’s raining so it obviously gets returns from rain (and through it). But it will depend on the processing they do from the sensors. But just so we’re clear, cameras also work in the rain and snow. I don’t think one is clearly better than others.

Radar and Lidar also get a lot of noise from heavy rain or snow. Fog can be just as bad. Some conditions just aren’t safe to drive in, regardless of who’s driving. I don’t think either of them are trying to design a system for those conditions.

On a personal note, I have no interest in getting a ride in a self driving car. I do have an interest in an empty car that can drive itself. Drop myself off at the airport, valet parking downtown, easier to share one car per household, river shuttling, through hike shuttling - I would use it a lot. I understand the more profitable goal is taxi services, but I don’t want that. So in my narrow use case, I hope Tesla succeeds since that approach can be used on personal vehicles anywhere while Waymo is strictly city taxis, which I don’t use.

Chess is a very complex rules game, while Checkers is quite simple. Waymo has a complex approach to self driving:

• Expensive suite of sensors
• High resolution maps of operating areas
• Remote operators standing by

While Teslas approach is simple:

• Capture a bazillion miles of camera footage, feed into AI, profit?
• Unpaid volunteers teach the AI safe driving
• Car has only a basic map for routing, the rest is inferred in real time from cameras

Waymo’s successful approach scales linearly. They have to high-res map every city they want to operate in, and they can gradually bring down the cost of the sensors. They will require fewer remote operator interactions over time.

Teslas success is more difficult, but it scales exponentially. They already produce vehicles at scale and full control over all the equipment on board. The existing fleet would be able to participate as well. If they succeed, they may want to offer buy-backs for customers who didnt buy FSD - the cars would be worth more to Tesla than the owner.

In both checkers and chess, the player gains super powers for reaching the other side of the board. Time will tell who reaches the other side of the board first. They are playing different games on the same board. Okay that’s fair.

I’ve been using Piwigo for the past 4 years. The video plugin kinda half works (breaks during upgrades, doesn’t work on Android). It would be cool if Live Photos end up supported, as that’s my main reason for trying out alternatives. But since Live Photos are part video, which itself doesn’t work, I’m not holding my breath.

Yes but in Immich each user has their own independent album/gallery, whereas Piwigo is a single gallery with different access rights to users.
