Docker will set the default behavior of FORWARD chain to DROP, and then this make the home network of my friend off from the internet completely...

GeoIP is the last way. Before that, geoclue will try to locate using found Wi-Fi and Cell towers via beacondb.net (via Mozilla Location Service before it shut down). If beacondb.net return fail or (0, 0), it try GeoIP at last.

In most cases, yank in Vim just need somewhere to store contents temporarily, not share it with others.

Yes. The original Ethernet use Coaxial Cable with bus topology when it was standardized at 1982. This way was used by its competitors like Token Ring as well. 10BASE5 use thicker coaxial cable so it called thick Ethernet and 10BASE2 called thin Ethernet. (5 and 2 means it can reach 500 meters and 200 meters)

And then the engineer of AT&T want to reduce cost so they found the phone line. At that time, the phone line use twisted pair line and usually have many unused pairs in the line to a office room. So they think those pair can be reused so there is almost no cost for line. Since the phone line already use star topology so they choose it as well. 1BASE5 was standardized at 1986 (so the twisted pair ethernet have lower bandwidth than coaxial ethernet at beginning) and also called StarLAN (was renamed to StarLAN 1 when StarLAN 10 was invented at 1988). And then at 1990, 10BASE-T which is based on StarLAN 10 was invented. The last is the story we all know today.

When I see the title, I initially thought you are talking about 10BASE5 and 10BASE2 (old Coaxial Ethernet)... I just know about DOCSIS technology, but I have never used it. In my hometown, most people switched directly from ADSL to FTTH.

He may want to say "fastsync" (whose kernel part called winesync). It's the predecessor of NTsync and was renamed to NTsync when merged into linux mainline.

Before NTsync was merged, those distrobutions provides the kernel packages with winesync patches. Since linux 6.12, NTsync was merged so they droped winesync from kernel package. But NTsync's API is different with fastsync/winesync, so old wine with fastsync support will stop working with new kernel. (While NTsync still isn't merged to wine)

And snapshot can benefit backup. Since some software need to be shudown to do backup, minimize the down time is important. The snapshot can make down time is almost stop and restart time, and the software can be online again and we can do backup on snapshot in background.

https://esp32-open-mac.be/ is working on reverse engineering ESP32 Wi-Fi hardware to implement a open source ESP32 MAC and PHY driver.

AFAIK, Mopria doesn't develop universal printing standards actually. The IPP standard was developed by Printer Working Group of IEEE. Of course, its members are almost same as Mopria. The standard Mopria developed is eSCL, a scanning standard. eSCL has a competitor, WSD, which was developed by Microsoft.

For forecast, you can selfhost a Open-Meteo. But note this need a lot of RAM and storage to run the weather model.

HM-SMR works better than normal DM-SMR, but it's rare and limit the filesystem choice: none on Windows and f2fs or btrfs on Linux.

Suggest use fsfreeze --freeze to block all access operation to create a stable image without unmount the SD card. (And release it later using fsfreeze --unfreeze.)

BTW, this feature was created by XFS and was moved to VFS in Linux 2.6.29 so all filesystems supported by Linux gained this feature.
