Edison is reported to have said that he never had a failure when he was inventing the incandescent light bulb, he just found a thousand (or several thousand - whatever the number, it was a lot) ways that didn't work.

I've regularly had not-failures like that over my lifetime, so I just try to think of myself as being in good company.

Unless they make you do it with an app on your phone. ;-)

So it'll be warm enough to melt the butter, of course. (The purpose of bread is to hold butter, you know, although after that you can add other things for variety.)

And the price for a 4x8 foot panel will be?

I can still remember 3 things that LS/MFT stood for.

I had the same problem with an HP all in one with an OS upgrade on a Mac Mini. The old driver would no longer work, and HP had no replacement for it. I lost the ability to scan to the Mac from the printer. I can scan using an HP app, but I frequently scan multiple pages manually into a single document - something I could do at the printer with the old driver. But doing it with the app requires going to the keyboard after each page to tell the printer that there is another page - not really convenient when the keyboard is several steps away. Luckily the printer also talks to a Win 10 box that has the old driver, so I scan to that one when necessary and transfer to the Mac with a thumb drive.

The printer/scanner is about 10 years old. When I called HP about the driver they said their machines were designed for about a 5 year life and if mine was still going after 10 I was lucky goodbye.

I bought a new HP printer/scanner in hopes it would scan to the Mac directly but no luck - only with the app. Took that printer back the next day.

What happens when it rains?

It will be interesting to see if this works out. When airplanes were small, slow and short range the lighter than air machines could be competitive in some applications. But as engineering and materials technology improved all aspects of airplane capabilities, the advantages of blimps and dirigibles disappeared in all but the most niche of markets (think: Goodyear Blimp, and what else?)

People have been trying to bring back lighter than air for decades - see, e.g., The Deltoid Pumpkin Seed, a Profile I read in the New Yorker's 2/24/1973 issue, about a design which (IIRC) included some airfoil features intended to give better lift and speed than the traditional blimp shape. But I suspect the huge impact of winds on performance, both on upwind speed, performance in storms, and on ground handling (requiring tethering towers, ground crews to handle ropes, and HUGE, closed indoor facilities) are likely to always crush whatever lift advantages may remain with helium.

I do hope I'm wrong, though, because these things are really cool.

I use Carbon Copy Cloner for automated backups - in addition to the Mac Mini's built in Time Machine. My photo image files live on an external SSD, and are copied nightly to another external hard drive (spinning disk) as backup. I have different automatic backups that run on different schedules for backing up other files to other external backup destinations. Carbon Copy Cloner is vastly configurable.

At our high school, there was a Junior class trip to DC over spring break to "meet our elected representatives" and tour the capital. My class went in 1960, on a chartered Connie. I'd flown before, over the Continental Divide 8 times in DC3s (Frontier) and once over the farms of Illinois in a DC7 (Delta, I believe), but I thought of the Connie as something special. The only thing that stands out in my memory of the flights to and from DC, though, is how "cozy" the Connie felt for what looked like it would be a really big plane.

I had occasion to order some friction primers for a black powder cannon a few years ago. They were just shipped with an invoice. (This is a VERY niche market in the US, with only a couple of suppliers that I could find and I'm sure that almost all product goes to Civil War reenactors.)

It goes back a lot farther than 1936.

Personally, I never want to get attacked by ANYthing that has to catch, kill and eat things to stay alive. Of course, bears would be right at the top of that list.

Re: shipping - Priority Mail Flat Rate boxes are frequently the cheapest way to ship lead. The boxes are free, and you can print mailing labels on your own computer using the USPS web site. Pure lead is not a problem. Some of the companies that sell bullets for reloading ammunition use it - one even has its "case" quantity set at the number of bullets that is just under 70#, the maximum Flat Rate weight. But check on whether the paste and/or rosin core are a problem.

The Brits have (or at least had) one of those. Made a whole TV series about it. (Yes Minister, for those of you who don't know - an absolute hoot, especially Sir Humphrey's monologues explaining why what the Minister wanted to do wouldn't work and only what the permanent staff (meaning he) wanted to do, would.)
