please do yourself a favor and don't remotely deploy rpi or anything that uses microsd cards for OS image and boot. The write lifetime of those, even using "industrial" cards, will mean a huge failure rate even with very light usage. Only use some sort of real sata3 or nvme bus SSD.

There are ways to reduce the risk, though, depending on your workload. It is possible to use the sd card just to boot, with all actual file systems in a USB attached device. You can also use some of the (very limited) memory as a ram disk for things with lots of writes...

On the one hand, I completely appreciate this. When I set up NTP, I'm careful to think through consequences and tread lightly. After all, I learned my sysadmin skills at a university before the September that Never Ended, so it really was a collegial place back then. On the the other hand, the internet is a much bigger place. Things are orders of magnitude more complex. The feedback loops that made NTP work well in a…

I do agree. A complete solution is designing a new generation/revision of time protocol with accountability and anti-misuse as parts of its design, just like how people are implementing ASLR and NX in C programs and starting to use memory-safe languages. Or just see how TLSv1.3 removed all unsafe algorithms, so it will be little damage even under the worse case scenario. Also, I think NTP needs more publicity. We nee…

I use Safari on macOS. When I need to google a term, I highlight it, and then press ⌘C, ⌘T, ⌘V, enter. (Copy the search term, open a new tab, paste into url/search bar, search term) I've gotten quite fast at the keyboard sequence; it takes maybe one second total. I imagine I could make this process even faster with a plugin, But I see no need. I would like to think that most Windows machines would let you be similarl…

Can't you just right click and search from the context menu, since you just highlighted the term so the pointer ought to be in the vicinity.

There doesn't need to be a new revision when you can accomplish all those goals by running your own stratum 1: https://www.amazon.com/TimeMachines-TM1000A-maintains-broadc...

Good a place as any to mention my short story https://slashdot.org/comments.pl?sid=7132077&cid=49308245 possibly the only work of fiction ever inspired by NTP, IoT and cryptographic protocols. This struggle with embedded ip address seems to echo this part of my story, "These hastily made things flooded the market and soon replaced other well-documented things. At times something failed and its inventors could not say…
