I think that’s a very strong argument and a great metaphor, but you forget relativity.

All reference frames are valid - you could say the Earth and the people are moving and the train is stationary, you could say the train is moving and the earth and people are stationary, or you could say they each have a vector moving around the sun or anything else

But when you travel through a portal, the only valid reference frames are you and the entry portal. Your momentum relative to the Earth doesn’t matter - why would it? You can open a portal to the moon and jump through, and we see momentum is preserved. The Earth isn’t a special reference frame, it’s just the most noticeable one.

So let’s pick the reference frame of someone on the track. Let’s look through the portal and say there’s a sign on the other side - as it approaches, you’d see a sign approaching you through the portal. Relative to you, through the portal the sign is moving at 30mph. The portal passes over you - you haven’t moved, but you enter a new reference frame, a frame in which the Earth and everything on it is moving at 30mph

This actually gets me thinking… Is anyone actually working on an aids vaccine? Maybe mRNA could do something there, theoretically it should be able to grant pretty much any type of immunity you can have naturally

Not a feat of engineering, a feat of marketing

Because immunity varies by disease.

Chicken pox? Pretty much one and done. COVID? Falls off rapidly after 3 months, whether you catch it or get the vaccine

Plus, every mutation is a dice roll on how much existing immunity will apply. It could be exactly the same as the last strain, or the old immunity might not help at all

After tech Jesus posted that, a former employee came out about all sorts of stuff about the work environment were pretty horrible

IDK if you can convince it to run on Linux, but I’ve been pretty happy with paint.net lately

It’s basically a newer project like gimp. It’s got the core abilities and appearance of Photoshop. Feature wise, it’s less than gimp or Photoshop, but what it has works decently well

Most importantly for me, the UX is much better than gimp… Not as good as Photoshop, but I find stuff is usually where I’d expect it to be

Obviously it’s built on .net, so theoretically it could run native on Linux… Not sure if anyone has done the work to make that actually happen
