I'd feel much better if reddit and twitter were even handed with their condemnation of comically hateful people. As someone on the Left, what I've seen is that Left-leaning media bias tends to give indirect license to the most extreme authoritarian and even toxic fringes of the Left. It also fuels a reaction from the far Right.

For as long as Fox News exists and promotes itself as an actual news agency (HAH!)

The mechanism I cite above has been in operation at Fox, just in the other direction.

Used to be about half that pre-Euro!

This is almost the direct opposite of my own experience.

Got an AirBnB in Montreal Canada in December 2016. The photos were great. The owner was quick to respond. So I booked it and reached the place.

Bummer 1: No cable. ( But in the listing it was there) Bummer 2: No safety. The owner had converted an apartment into two, separated by a thin wall. The wall had come off and he had the gypsum wall leaning and cautioned me not to touch it.

Since it was for 2 days and in the middle of a heavy snowfall, I let it pass. Fast forward some hours, a couple of people checked into the other half of the apartment, started playing loud music, shouting and smoking. The smoke started coming into my half of the place because the wall was not really sealed.

Experience 2:

Rented a place which had a profile photo of a family. I thought great ! When I checked in, I felt it was some sort of "setup" just for the purpose of renting it out for AirBnB, I asked the owner where she lived. She said "nearby". I felt something fishy as there was no family ! The reviews even said there was a family (fake reviews ? ).

So after the owner left, I googled the address and to my surprise, I found that the address is under a rental agency. Next I found that the door lock is not working and internet is less than the speeds of dial up. I left the next day and disputed it on AirBnB.

AirBnB said, "Its legal for rental agencies to list on AirBnB". ( what was the photo of that family then ? ) Since AirBnB was not willing to refund and gave me a 25$ coupon, I disputed with AMEX and got all my money back.

That was my last & final stay using AirBnB. Deleted my AirBnB account after this incident.

Elaborate?

Still useful for Javascript, as the bit shift operators work on 32 bit "registers".

It's pretty easy to write the decode for the 0-91 integer in Javascript.

    if (ch == "!") {
        return 57;
    } else {
        return ch.charCodeAt(0) - 35;
    }

I'm probably going to go to typed arrays of 32 bit values. Currently, I can encode an entire ship's data in 18 bytes, of which 4 characters is a hash id.

Sorry. Go back and study thermodynamics again. If you have the energy to generate hydrogen, you might as well use that energy to move the ship. You're always going to spend more energy generating the hydrogen than you will get back burning it or combining it in a fuel cell. The one exception is if you start from just the right feedstock to generate the hydrogen from, like some hydrocarbon. The leading candidate now is natural gas. However, in that case, the byproduct is CO2 -- so what's the point?

Or, maybe you were thinking of hydrogen as energy storage? Batteries are far better than hydrogen as far as that goes.

Storage for hydrogen can be really large, in the TWh size. Because they can use natural gas storage tanks. There's nothing that big for batteries. The big Tesla solar installation on that Samoa island was six megawatt hours, with 60 battery packs.
