Currently prepping a new Stratipi build with a TON of fixes, both for internal FreeBSD things and for Stratipi specific things.
While debugging entirely unrelated graphical issues, I might have accidentally stumbled upon the solution to all the serial port issues I've been facing !?

Testing an experimental build of #Stratipi here at the OpenZFS User and Developer Summit!
They needed a time source to test cluster synchronization, and I just happened to have brought this with me to do some updates and hacking on it hahahahaha

Sometimes I pretend to be a YouTuber! And this is one of those times.
Today I'm detailing some of the work I've done with Stratipi over the past year and where things are headed going forward.
SPOILERS, I'm building more than just a simple NTP server ;)

4) Tons of minor fixes everywhere listed in the CheckMK Dashboard
4X) Adding NTP client to CheckMK so its VMs will maintain real time sync (WITH MY STRATIPI NTP SERVERS!)

A little context...
I created a build system for Stratipi, my Raspberry Pi time server over the past half-year.
Now I'm ripping the entire thing apart, pulling out all ARM, Raspberry Pi, and Time Server code entirely.
Alls I can say is that this was intended from day-one, and gonna be AWESOME ;)

I decided to up the "resource limit" on my #Stratipi living in the global public NTP server pool
But I also swapped from a "debug" kernel to a "release" kernel, so I'm using LESS resources for 3x the number of clients/sec!
stratipi.com will have all the details once they're compiled and cleaned :)

On my build server, it takes about 40 seconds to generate a Stratipi.com build image to test.
Today, I put the build environment on my MacBook M5 MAX so I can bring it offline to the #FreeBSD Developer Summit next week...
It built in 9 seconds.
I LOVE this laptop. It's a DREAM!

This build has passed every test I've got, and I've also been testing Stratipi.com against the #FreeBSD 15.1-BETAs and 15.1-RCs this whole time too, so zero surprises!
Its been 2 months since the last public build Stratipi, because I've been waiting on 15.1-RELEASE

No NORMAL user has to worry about this particular one :P
It is very specific to FreeBSD, using ZFS on the Root filesystem, on a computer that doesn't have a physical RTC (so ARM/RISC-V SBCs)
The pre-made FreeBSD images are all UFS which don't have this issue.
stratipi.com is ZFS on Root tho :P

Stratipi running on a Raspberry Pi 4 was just accepted into the public NTP pool.
And now I'm serving thousands of clients per minute!
I'll share more detailed graphs later after this has been running a while.

My journey with a complete and total transition over to MacOS continues.
Last night, started working on Stratipi again.
No Rufus to burn the images? Sure, let's just use the Raspberry Pi Imager instead.... oh wait... oh... never mind then.

I'm at the "fun" part where I broke stability on only the Raspberry Pi 3 with some code change in the past month w/ Stratipi.
Worst part? It is a timing/race condition that takes 5-15 minutes to activate, so each bisection test, I just have to sit around and wait to see if it breaks again...?

I'm doing some stability testing w/ it on Stratipi.com software this week, and it makes me want to throw the hardware out the window entirely!

I'm essentially in full "polish" mode with Stratipi at this point.
Super Freaggin Happy with how this project is coming along!
Quite a bit of the system is hardened and battle tested at this point. This thing is well beyond "minimum viable product" and could be considered "complete" at any time.

Want some Pi!?
Check out Stratipi.com - my custom built NTP server!
By the way, you don't actually need GPS to use this project! It will naturally fall back to a Stratum-2 server if no GPS is available.
Give your network a single local time source today with Stratipi. :)
