Just wondering what people are using to meet the 2FA requirement GitHub has been rolling out. I don't love the idea of having an authenticator app installed on my phone just to log into GitHub. And really don't want to give them my phone number just to log in.

Last year, we announced our commitment to require all developers who contribute code on GitHub.com to enable two-factor authentication (2FA)...

I currently have a Dell laptop that runs Windows for work. I use an external SSD via the Thunderbolt port to boot Linux allowing me to use the laptop as a personal device on a completely separate drive. All I have to do is F12 at boot, then select boot from USB drive.

However, this laptop is only using 1 of the 2 internal M.2 ports. Can I install Linux on a 2nd M.2 drive? I would want the laptop to normally boot Windows without a trace of the second option unless the drive is specified from the BIOS boot options.

Will this cause any issues with Windows? Will I be messing anything up? For the external drive setup, I installed Linux on a different computer, then transferred the SSD to the external drive. Can I do the same for the M.2 SSD – install Linux on my PC, then transfer that drive to the laptop?

Any thoughts or comments are welcome.

Edit: Thank you everyone! This was a great discussion with a lot of great and thoughtful responses. I really appreciate the replies and all the valuable information and opinions given here.

Here's a few that I know of. What other things are commonly running Linux that most people may but be aware of?

• Ingenuity (helicopter drone on Mars)
• Smart TVs and streaming devices (Samsung's TizenOS and Roku devices)
• Smart appliances (Samsung's smart refrigerator)
• Digital signs and billboards
• My car stereo (Sony XAV-AX6000)
• The Large Hadron Collider
• FAA Air traffic control and radar systems
• Self driving cars

If you're from a non English speaking country, do you first have to learn English if you want to get into programming?

I've recently switched to Firefox mobile on Android after having used Opera mobile for the past 10+ years.

The feature I absolutely love on Opera mobile is it will dynamicly wrap text and adjust the page layout to a single column when you zoom in/out. So for pages with small text, you can zoom in to see enlarged text and just scroll down to read - where on all other browsers you would have to scroll horizontally back and forth to read the enlarged text.

Opera has been doing this brilliantly for at least 10 years, and I have yet to see this on any other browsers I've tried. Does this functionality exist within Firefox, or is there a plugin that can do this?

I know the correct answer is to stop using Facebook, but there's a couple communities I follow for certain updates I can't get anywhere else.

Is there a good third party open source app for Android?

The UNO R4 WiFi model will use an ESP32 chip for built-in WiFi and Bluetooth, and includes a 12x8 LED matrix along with some other new features. The boards now support up to a 24V power input.
