Let me explain. All of questions are great, it's that to explain some will
require books, those are hard and there are no simple answers. Others are
easier to put into context.
Let's take state of preparation. I've been through a handful of serious
hurricanes, but everyone I know thought this would be like those before.
Unfortunately the magnitude of devestation compared other storms was
nothing close to the collective known experience, so few prepared
sufficiently, across the board government, utilities, private sector,
citizens.
So the go!den question, knowing what we know now, will for the next one
will we be better prepared. That's a more complicated yes and no. For the
entities that can afford it, sure. Those that can not afford it, will not.
Hello Kevin,
thank you for your news from Puerto Rico.
The media reported a lot about the difficulties restoring power (and
potential scandal involving Whitefish Energy).
I haven't heard much on a personal level, only
- my cousin is relaying ham radio messages via NYC
- my doctor's family (from Puerto Rico) may move to the mainland
I'm not familiar with the government of Puerto Rico. It would be
interesting to hear your views on the political leadership, state of
readiness for emergencies, efficiency of response, etc.

From: Kevin Shockey <shockeyk(a)gmail.com>
Just started laying the ground work for a mesh network here in Puerto Rico.
<snip>
What have you heard about the communications challenges after the
hurricane? Any questions?
Im still investigating the gap between what is possible versus what is
feasible versus how it actually happened (what we learnt from the actual
experience).
Most people stayed connected using smartphones post disaster. As wheels and
spokes came on line then more pc, laptop, tablets came online.
As the cell network was repaired, then I started doing a mobile hotspot in
my house, or usb tethering. I have to assume other tech-savvy families did
the same.
I know some first responders, but there is a lot more to learn about the
comms implications for search and rescue efforts.
If you think of us a rural/urban networking topology, most of the San Juan
metroplex is fine. Within that area are pockets without power, water,
Internet.
Then in most of the larger cities the same, now we switch immediately to a
rural model. Spokes of functionality extending into smaller pueblos. If the
spoke you live on is with out a service, then everyone down stream is
usually without that service.
It turns out that the utilities were laid out in daisy chains. Many the
chains that are completely inoperational may take years for the
infrastructure to be rebuilt again.
Hey mesh people,
Have you been dying to help build the People's Open Network, but aren't
sure where to start. Maybe you've heard about our mysterious node mounts,
but don't have a smartphone or aren't part of some __super secretive chat
group__. Or perhaps you'd just like help selecting a local ISP for your new
apartment. Fear not, we're here to help.
Starting this Sunday, Feb. 4th, SudoMesh will now be holding regular
"office hours" on Sunday afternoons in SudoRoom. Running loosely from 1pm
until late afternoon or early evening, this time serves dual purpose:
1. A jumping off point for people interested helping with a scheduled
Sunday node mount, but who are not able to attend a Tuesday night meeting
or are not "in the know."
2. A friendly, non-confrontational time for new people to get oriented to
the project or just ask general questions about networking, the internet,
and their service provider.
Finally, when either of these purposes are not present (i.e. no node mount,
no new people), we will use the time to hold training sessions on a topic
of choice, conduct outreach to potential node locations, address finances
and purchasing, or tackle any other outstanding issues.
For this Sunday, we do not have a scheduled node mount yet and do not
expect new people (since this just now being announced). Instead, we will
be doing basic training on how lead or participate in a node mount. We will
also be contacting and scheduling our existing list of node requests.
If you'd like to help out, stop by SudoRoom on Sunday, Feb. 4th, around 1pm.
Thanks and hope to see y'all on Sundays,
-grant
PS: if someone with access would like to add this as a recurring event to
https://omnicommons.org/calendar/ that'd be cool, or we can just discuss it
on Sunday :-)
Hey meshers,
In yesterdays meeting, we discussed a couple of open issues namely:
https://github.com/sudomesh/bugs/issues/4 (can't connect to netflix)
https://github.com/sudomesh/bugs/issues/5 (syslog logging on home
nodes)
and
https://github.com/sudomesh/bugs/issues/8 (intermittent dropping of
tunnel digger sessions)
I've marked these issues with label "help wanted" and other appropriate
labels like "firmware", "exit node" or "outreach/communication".
These triaged issues/bugs can be found through https://peoplesopen.net/
helpwanted .
How can you help out?
1. If you are interested in fixing issues, have a look at https://peoplesopen.net/helpwanted for some selected issues.
2. If you are aware of an issue but don't have time to fix it, please
please document and label the issue such that others can pick it up.
Please review existing issues at https://peoplesopen.net/issues )
before opening a new one to avoid duplicate issues.
3. If you are familiar with (parts of) our projects and feel like
cleaning out stale / out-dated issues, please have a look at https://peoplesopen.net/issues and help close out issues that have been addressed
and label issues that need attention.
If this is confusing, don't know where to start or if you have other
ideas on how to encourage folks to help out, please contact me (or
someone else!) offlist.
Hope this helps,

we got a donation that included sixteen or so of these little modules, for
converting 48VDC from Power Over Ethernet to like 5V or maybe 12v or whatever
you want, it has an adjust pin.
they're in the mesh area on one of the first shelves on the left, around eye
level. Part number is AG9800M and they're made by Silvertel
here's the datasheet:

Hi all,
Watching the excellent panel discussion (great moderating, Mai!) at BYOI
yesterday < https://m.youtube.com/watch?v=VaFFFw0hndQ > I was struck by the
connection to a conversation with my colleagues at Tech Underground about
setting up Internet/Intranet for small nonprofit organizations. We learned
that AT&T's fibre 25/25Mb plan has an issue where you can only use the
Arris BGW router they provide, and that this router will reboot itself
whenever the NAT table sees more than 800 TCP sessions. 800 is pretty much
normal for a group of about six people. So even though AT&T promotes this
setup for organizations up to 25 users, it is not. The router reboots
itself when 800 is exceeded, so everyone loses connectivity. The limit may
vary depending on unknown factors, but also exists for Comcast small
business customers, e.g. the limit is 2000 on the device provided by
Comcast, but that the device itself eats up 700 or 800 sessions, before any
traffic from the network has even been hooked up to it, leaving maybe 1200
for users. With a dozen staff, plus people's cell phones and VoIP phones,
it hits the limit and crashes the router once or twice a day.
Online research turned up a couple of people attempting hacks:
1. Super-linux-geek hack: http://blog.0xpebbles.org/
Bypassing-At-t-U-verse-hardware-NAT-table-limits
<http://blog.0xpebbles.org/Bypassing-At-t-U-verse-hardware-NAT-table-limits>
(basically, the hack is to take the DRM traffic to the AT&T router, and
everything else to the router of your choice.)
2. http://www.dslreports.com/forum/r29898675-U-Verse-
Business-NVG585-NAT-limit
We think AT&T is trying to reduce the number of customers who will try to
share accounts, and live with the reduced bandwidth. TCP session limits are
a big hammer solution to this problem, but it's one of the fall-outs of
having "net neutrality" rules. If they can't rate-differentiate sources,
ISPs will manufacture artificially handicapped hardware.
thanks
Hilary

You can download some clips from tonight's event I shot with my iphone
for b-roll. I shot through the demonstration tables to the stage in
most of these clips. So, most have a demo table and part of the stage
in the shot. I think a still frame could be good for social media.
More video coming tomorrow.
