http://livingstingy.blogspot.com/2022/12/ford-mustang-mach-e.html?m=1

I had a chance to see a Ford Mustang Mach-E up close today and speak with the owner. He bought a basic model for about $42,000 sticker, with a 250-mile range (a little light - 300 seems to be the "go to" number these days). But it was interesting to see.

Even as a base model it had a nicely stitched leather interior. And all the door and body panels fit properly and evenly. No trim pieces were falling off or loose. It had the build quality of a typical Ford - perhaps slightly better - and that is not a bad thing. Ford has made millions - billions - of cars since 1908. They seem to have it figured out.

It is about the same size and shape as the Tesla Model Y, which unlike the Model-X, ditched the troublesome and pointless "gull wing" doors. Given the bad press about those doors, I think they are not a selling point, but detract from the value of the Model-X. The big difference is in price - the Tesla Model Y is nearly 50% ($20K) higher in price - and there is a substantial waiting list to get one, too. The model X is more than double the price of a Mach-E.

If you need service for your car, well there is a Ford dealer in nearly every town in America. Granted, not all may have qualified mechanics (yet) to work on the electronics, but everyday items, such as body, trim, brakes, and whatnot, can be repaired at the dealer. Tesla? The repair centers are few and far between, and the wait times for parts and the difficulty of repair are legendary.

And this is just one product from one manufacturer. What will the EV market be like in 2023 and beyond, as nearly every automaker on the planet offers a line of EV models? Tesla has made big noises about its poorly designed (and embarrassingly named) "cyber-truck" which, like the Elio, is slated for production "next year" (every year). Meanwhile, Ford and Chevrolet are actually selling EV pickups, without fanfare or noise or hyping their stock price on Twitter. And despite the FUD, they probably will sell well for a niche market of users.

Tesla's P/E ratio is down from a staggering 1000 thanks to the collapse in share prices (investors are seeing the writing on the wall) to a still staggering 45 or so. 20 is a more rational target - either Tesla has to double profits or the share price has to drop by half to be rational, particularly in an era where Savings Bonds (Series I) are paying 6% or more for chrissakes. Ford's P/E ratio is down to less than 8, which means Ford is earning a staggering 12.5% on investment, and paying dividends to boot! The latter is something Tesla never has done and promises never to do.

It was a nice work, but unfortunately the American government does not have any green-skinned, small-stature, big-eyed space species. I did not say there are no aliens, the results show that the alien type has not contacted us yet.

Hi, /sci/

https://academic.oup.com/schizophreniabulletin/article/43/2/236/2797765

This article talks about how psychosis and sexual trauma can cause gender and sexuality confusion. I suspect I have that but I'm worried if I talk to a therapist about it (or anyone else for that matter) they will try to "affirm" it, which I don't want.

Does anyone here know a "renegade" psychologist who can help me?

Can it be reversed?

I remember hearing about a theory that homosexuality is caused by intestinal parasites wanting to propagate themselves through gay sex.
Does anyone know anything about that? Is there any research on it?

Senior in electrical engineering here (computer and electrical engineering share about 50% of their curriculum at my uni)
What others said, building a PC is a good idea. I've never had enough money for a PC though and have been coasting through college with a ditched laptop that I fixed.
One hobby I took up when I was figuring out what to study was getting obsoleted PCs off surplus auctions or from family members, lobotomizing them and experimenting with linux distros. You can make your own servers for storage and mail etc.
Another thing to play with is RaspberryPi and/or Arduino projects. There's tons of resources on those and honestly should be the focus of practical teaching in universities (but often aren't)

Can someone explain a quadratic equation in a way that makes it more intuitively understandable? My algebra teacher just rambles endlessly about unrelated shit.

Dude, you're responding to a question from three years ago. I'm sure OP has since learned what a quadratic equation is, or they don't care anymore.

Your method seems a tad too complex for my liking. Why do you think it's better than simply remembering
x = (-b (+/-)sqrt(b^2 - 4*a*c))/(2*a)
? That's a single formula that solves any quadratic equation in a single step.

Now it's even farther in the future and the quadratic formula hasn't changed a bit. I hope OP is ok.
