How to capture weather satellite data
Can I Get Satellite Data With An Umbrella?

I was able to download images and weather data from GOES-East, NOAA satellites, and Russian METEOR satellites. I also got a little bit from some other satellites but the signals weren't as good.
Here's the stuff I used (these links give me a commission if you buy stuff through them, but the price to you is the same!)
Umbrella: https://amzn.to/3FEpY6t (any umbrella should work)
Foil tape: https://amzn.to/46RBNCk
(This is actually cheaper at a hardware store, and you'll need 3 rolls!)
Antenna feed: https://amzn.to/46UMvrQ

Antenna cable: https://amzn.to/46QiFVn
SDR++ software: https://www.sdrpp.org/

I also used Stellarium for aiming, but I still don't really love it.

On using physical security keys (YubiKey)
I use Two-Factor Authentication with several applications and while they're quickest with my smart-phone, they almost all have the option of calling me on my landline to provide the security code.
I haven't used any of the physical security keys in years, primarily because I was too cheap to buy a personal one several years ago (I did use the old code-key generator devices for work years ago). Of course, losing or damaging one of these keys is always a risk, and if it's left plugged in to the device, that doesn't really secure it from anyone who somehow gets access to (by stealing the device for example).
As mentioned in the article (https://www.theverge.com/22458935/two-factor-security-key-how-to-yubico), the Yubikey can be used as part of your logon authentication to Twitter, Facebook, Google, Microsoft, and many other applications running over the Internet. That is probably where I would start because our userIDs and some of our passwords are likely to be available on the dark web somewhere (you need to set up Two-Factor Authentication for them first).
As an aside, if you have a password manager like LastPass, then you can fairly easily set up unique UserIDs and (most important) unique passwords for each of them. LastPass can be added to most browsers to fill-in your credentials for you (that's what I do, primarily with FireFox), or you can use LastPass to launch the sites and login to them for you (like some other password managers, I can access LastPass locally {on my PCs}, from my phone, or from the Internet - it's the same database everywhere).
"If you lose your security key, you can use two-factor authentication on your cell phone or an authenticator app. Then, if you want to use a new key, you will have to go through the process of reauthorizing your accounts all over again.
...
In order to use a security key with your Google account (or any account), you need to have already set up two-factor authentication."

Your operating system may support encrypting individual drives, folders, or even files (after backing them up) and you could store the encryption keys in your password manager or a security key.
If I were to encrypt an entire drive or device, I would make sure I had a current & tested backup of it first.

GentleCure Image-Guided SRT - skin cancer treatment
Skin Cancer Can Be Cured Without Surgery: (855) 936-4411
For years, Mohs surgery was the standard treatment for people with skin cancer. Now, people with basal or squamous cell skin cancers have Image-Guided SRT (superficial radiation therapy) - the treatment option that cures skin cancer without surgery.

"Low amounts of X-ray energy are used to kill the cancer cells, which lets healthy skin grow back.
Uses SRT technology with ultrasound images to find, measure, and treat the skin cancer cells and see it shrink over time to be sure the cancer is cured.
Anesthesia is not needed.
Fifteen to 20 short treatment sessions (about 15 minutes each) over the course of several weeks."

SRT treatment for skin cancer gains popularity, but it's not for everyone (2017):
What Is Image-Guided SRT (IGSRT) 2023?
"SRT has been around for years, but image-guided SRT is the first skin cancer treatment that uses an ultrasound probe to visualize the tumor. In the ultrasound images, healthy tissue appears on the scan in yellow and green while the skin cancer shows in black.
The images allow the doctor and radiotherapist to see how big and deep the cancer is at each stage of treatment. This allows them to target the exact depth where the treatment is needed to eliminate the cancer. The images also show the skin cancer shrinking over time, letting you know that your treatment is working."

The Treatment of Non-Melanoma Skin Cancer with Image-Guided Superficial Radiation Therapy (2021): https://pubmed.ncbi.nlm.nih.gov/33547631/
"Results: Treatment, guided by pre-treatment ultrasound imaging to adjust radiation energy and dose, combined with a fractionation treatment schedule of 20 or more treatment fractions, was safe and well tolerated. Of 2917 NMSC lesions treated, local tumor control was achieved in 2897 lesions, representing a 99.3% rate of control."
