Logged in just to upvote your comments. This is a place of intellectual curiosity, and I don’t understand those who expect knowledge to be spoon fed to them. If you don’t know a term, search engine it and work your way down the stack. You might find yourself pleasantly surprised you’re providing an NTP server in the NTP global DNS pool.

> search engine it... That is, go to google.com or DuckDuckGo.com and search for it... I mean, open the browser, click on location bar (on the top) and write... That is, if you are on Windows, click Start menu (which is now 4 rectangles),... Nevermind... /s

To downvoters: thanks, always appreciate that.

My point was that the OP can't guess their readers' level of knowledge, and it would be impossible for them to cater to all levels (as my attempt to explain searching... failed to show :-/) If readers don't know what NTP is, they should be able to either ignore the blog post or find the missing bits of their knowledge by themselves.

Yes, but even so, the write wear leveling algorithm in a $50 consumer class SSD and dwpd (drive writes per day) are vastly better than microsd media.

Will second this. A friend of mine had to write his own wear leveling software to make use of SD cards in his hardware, sadly bom made anything better way too expensive to be commercially viable.

If your friend has written about this anywhere or is able to share any code, I would love to learn more!

It’s so simple to setup your own Stratum-1 server, I don’t get why more folks don’t. The one I keep in my house is a 1U unit about the size of a 16 port switch and keeps time accurate to 15ns via a small Multi-GNSS antenna (yes, serious overkill for home needs, but I already owned it for a use case that used to need it).

Unfortunately, having more Stratum-1 servers does nothing to help clueless device manufacturers who hardcoding the IP address of an individual server, and damaging the community service. But yes, when we talk about the NTP community in general, we certainly needs more Stratum-1 servers. Nowadays, running a Stratum-1 is easy, the hardware is cheap, a single broad computer w/ time source from a shortwave radio or GPS.…

The way they burned the NTP addresses reminded me of Douglas Adams quotes "The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair".

I think that a pretty neat idea to solve all these time-related issues would be more digital wristwatches.

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…

I absolutely loved this, thanks for posting it. Do you have a list of your stories avalible?

But making sure that there is a wrist besides each clock is yet another problem.

That's what the towels are for.

This looks really cool. I may be deploying a fleet of Raspberry Pi or similar servers in the near future and this might save us a ton of headaches. The target context is a medical facility in a remote location without Internet (or extremely limited Internet), though. Is there a way to distribute updates by USB stick? What's the best place to read stories of people who have tried deploying with Balena on RasPi-type se…

Hey there -- we have a bunch of case studies on our blog, click the "case study" links on this page -- https://www.balena.io/customers/ And if you're interested in a board that is as easy to program as the Pi but more robust, you can check out -- https://www.balena.io/blog/introducing-project-fin-a-board-f...

Hi, thanks! From the description at https://www.balena.io/fin/, it looks like I'd be spending ~$170 instead of ~$35 to get:

  - Ability to run on 6V to 24V power
  - Low-power coprocessor
  - Battery-powered real-time clock
The rest of the interfaces all look pretty much the same, except that the Fin loses two USB ports and the headphone jack.

Given that my plan is to run off of 5V USB power and I don't intend to write special software for the coprocessor, can you help me understand whether there might still be good reasons to use a Fin?
