Hey Everybody,
We've got a meeting this Thursday November 18th, 2021 at 7pm - 8:30pm at
the Hudson Public Library!
Firstly, a big shout out to Joshua Stone for making the reservation at the
Hudson Public Library.
Secondly, the meeting will also be online at our usual Jitsi location for
people who can't make it in person. https://meet.jit.si/WlugMA
The topic we'll be discussing at the meeting is the Intel Management Engine
technology buried in every Intel CPU. This technology includes a version of
Minix running on a separate core inside your CPU you don't control.
Moreover, with the right software, changes to your machine can be made
remotely, even when the system is powered off (but connected to power). As
with all this stuff, of course since the whole thing is cooked into the
firmware, it's full of security flaws, etc.. We'll talk about those flaws
and how to disable it!
We'll also likely touch on the Tesla Dojo D1 processing unit. They've made
some claims that I've posted to the mailing list. Logan did some digging
and it turns out their claims are not as blow your mind as would be first
interpreted.
The Hudson Public Library does allow food and drink, so I will bring the
usual pretzels and snacks. Afterwards we will be going to Rail Trail
Flatbread <https://railtrailflatbread.com/>for dinner.
Toss me a line privately if you'll be attending so we've got an idea of how
many people will be going out for dinner.
I look forward to seeing you there!
Later,
Tim.

I just finally got to see the stuff about Tesla's Dojo Processor stuff.
9 PFLOPS per "tile" and 36 TB/s of bandwidth.

All,
To quickly summarize my problem/question, I’d like to host a nextcloud server at my house and be able to access it with the same hostname whether I’m home or away.
I own a domain, let’s call it example.com. Its main DNS record points to a node at digital oceans. However I’d like to host a sub-domain at my house, let’s call it home.example.com. Currently home.example.com resolves to a routable IP address at my house.
- When I’m on the road, I’d like to be able to connect to https://home.example.come
- When I’m home, I’d like to be able to connect to https://home.example.com.
The above works on a well-behaved desktop receiving dns servers via dhcp. Specifically, I have setup local dns to resolve home.example.com to 192.168.1.1. Searching this topic has taught me that this method is called Split-DNS.
However android and iOS do not appear to honer my local dns server — I’m not sure why — so they resolve the address to a routable IP and connect from within the private 192.168.1.0 subnet. My firewall sees this and drops it b/c it is a non-routable IP address connecting to the external interface. (I got this info by running tcpdump and watching traffic).
Has anyone attempted something similar? Is there something I’m overlooking? (Probably)
My goal is to not do special configurations on enduser devices.
Thanks,

Hey all,
I'm posting to confirm that the venue for our upcoming in-person meeting at
7PM will be held at the Hudson Public Library! We may also want to look
into eating options after the meeting, many of which are on Main Street:

My vote goes to the Rail Trail Flatbread which is close to the library and
has some incredibly tasty menu items!
And speaking of main streets, I'm happy to announce that Hudson has become
a semi-finalist for the Main Street Contest!

I think it's awesome that the town has seen so much growth since we moved
here and gives us a sense of community. I'm excited to see where it'll go!

Hey Gang,
My birthday is on the 11th and the family is taking me out for dinner.
We'll have the meeting on the 18th instead! I've got some ideas for topics,
but if someone has a burning desire to talk about something, let me know!
Otherwise I think I'll show off my experiments with TrueNAS scale.
Thanks,
Tim.
