Like Randelung said, that would be true if you couldn’t reset you password via email. But as long as that’s possible the email can’t ever be the 2nd factor because it can be used to (re)set the 1st one.
A safer definition of what the 2 factors should be is “something you know” and “something you own”. The “know” is usually a password (which you can remember, but you should use a password manager these days so you can have a different password for every service). The “own” is typically a phone these days (generating a timed code, for example). But it doesn’t have to be, it can be a physically USB dongle or your fingerprint. The idea is that it’s something that can’t be overheard, or recorded via key logger or or even told to someone.
Steam does this better (as in safer) than most.

That’s the point of real 2fa. And the prices of activating it also makes it very clear. I find it incredibly frustrating when I activate 2fa on some service, and they allow email as a callback that I can’t turn off. Cause that turns out back into single factor, being the email. That’s what the recovery codes are for.
Otherwise, if someone has access to your email, they can just reset the password and get access (cause that is the 2nd factor). Then they can change the associated email address and that’s that.

Germany looks like a dead straight line, yet the text says it could see a large drop by 2030. Sure, it could also see a large rise in arable land, no reason or context is given.

Normal bikes that you just push aren’t that stable without a rider, but you can get it some distance. They still fall over rather quickly. That’s mostly the form of the handlebars like gnu commented. And yes, without a rider, the gyroscopic effect is relevant. A bike weighs let’s say 15 kg, and a rider is commonly like 75kg. Of course removing like 80% of the weight changes if the gyroscopic has a meaningful influence. Add the rider back, and it becomes negligible again.
This is of course even more pronounced if you push only a wheel with nothing else, then there’s nothing left but momentum and the gyroscopic effect.
The reason you lean into a turn is exclusively the centrifugal force (not sure that’s the right twin), if you don’t you fall over because you have nothing to turn against. Changing direction needs something to push against.

The gyroscopic effect of slowly spinning, light bicycle wheels is negligible compared to the weight of the bike and it’s rider. If it was what keeps you upright, riding a tiny scooter-thing with skateboard/inliner wheels would be impossible. I mean those without motor, pedals, where you push yourself forward with one foot on the ground), often for kids.
What actually keeps you upright isn’t a physical effect, but just training your brain to instinctually keep you upright. While you’re moving, turning the handlebar effectively moves the bike below you left and right. So if you start tilting to the right, you turn right (slightly) so the bike/scooter is moving below you to compensate. That’s why learning to ride anything that is balancing on 2 wheels takes a relatively long time, but only once. Then your brain knows what to do, and it just works without thinking about it.

Yup, that’s the correct reaction.
- Comment on Idea: hardware manufacturers should publish RSS feeds for firmware updates 4 months ago:
I remember that Asus did this back in the day at least, not sure if they still do. But I remember having rss feeds for at least 2 of my motherboards in my reader, back when rss was actually widely used. It’s been like 10-15 years though…
- Comment on Dredge: Indie Darling to Get its Very Own Live-Action Movie 4 months ago:
This is probably the most unexpected game ever to get a movie adaptation. It does make sense thinking about the setting and story though, so I’m all here for it. Obviously depends highly on writer, director and probably producer(s), but let’s just hope they all get it. I mean it could happen, right?

Because you can’t read the article by reading it’s number, and there isn’t enough room for the whole article on normally visible parts of the body (not to mention the cost of that tattoo).
The QR code would give you a way to copy/paste the id so you can actually give and, you know, read the thing.
- Comment on Hardcore 7 months ago:
A QR code can also just contain plain text. It’s just usually used for URLs.

Hehe no problem, I was just rather confused when I opened the video and it started at the end (or rather didn’t start, obviously).
- Comment on 27 Unhelpful Facts About Category Theory 7 months ago:
You posted a link with a timestamp, which points to the end of the video. Weird…

You know you can turn off the music, right? Just play your own or none at all.

What low voltage though? Unless it’s 5V like USB (non-PD and non-QC), they should and need to be incompatible.
- Comment on Fallout 3: GOTY Edition is free to keep for the next 24 hours on the Epic Games Store 11 months ago:
You can use legendary worth heroic as a user interface (both open source projects) to download and play games you own on epic, no need to install their software.
- Comment on My first time playing Cities Skylines 11 months ago:
The point is to avoid left turns when merging onto or leaving from the smaller road above. Keeps the traffic on it flowing.
- Comment on 1 year ago:
Surprisingly, I don’t think Terraria has been mentioned yet. Dedicated server can be downloaded for free and fun on Windows or Linux. I’m relatively sure that even spontaneous hosted games (from inside the game) are LAN accessible directly.
- Comment on Epic is giving away 17 games as part of its holiday sale 1 year ago:
There is no need to use their launcher, as there are open source alternatives. “legendary” is a tool that can download sand install games from epic, but it’s command line only. Fortunately, there is also “heroic”, which is a GUI for it and honestly a pretty good one. Can also handle GOG games.
They work well for me, haven’t had epic’s launcher installed in a very long time.
