Introductions[edit | edit source]

Host nb infra to talk about ...

Loren - past work as cloud engineer, want to talk about networking, cli and ai tools
Zachie -- new to these listening in,
Elan -- do lot of self-hosting, interested in automated deployments onto k8s
Kevin -- lora testing of small devices, internal
Som -- no bg in hosting or infra, intrested to learn, find out
Doug -- here to learn about
Chris -- designer, web engin
Lauren -- infosec
Jameson -- smart buoys, interest all network, LoRA & LTE
Skanda - doing own infra
Andy - doodler - loves art
Prateek - interested to learn more
Wolfe - Self hosting for a long time. Interested in lower complexity.
Jams - he/him -- interested in general intelligence, and the fun conversations you have here
Mike - software engineer. unemployed. Self hosting a kubernetes cluster at home. Need to set up a self cluster and CI/CD pipeline on Kubernetes. Laptop for secure stuff that can be taken overseas.
Kevin. 🎤 It's been a while 🎤. Good to see you all.

Lesson or Demo[edit | edit source]

Read aloud: clarify for meetup. We are taking notes in a riseup pad (or I am--help appreciated, and links). We have meeting notes posted to the wiki. noisebridge.net, search Infra, or Meetups/Infra. (the Infrastructure page has a disambiguation link.)
Shell, web services, self-hosting, networking!

Reviewing networking protocols for the benefit of introduction to those not-in-the-know.

OSI 7-layer dip rehash:
Elan's purpose-based description of the networking stack.
Wolf: objects to the OSI model as not being relevant anymore.
Loren: discusses the SNAT operations involved in Jitsi communications.
LoRa
Jameson: discusses the [LoRa](https://en.wikipedia.org/wiki/LoRa) protocol, as the data link(?) layer.
Elan: LoRA uses [chirp spread spectrum (CSS)](https://en.wikipedia.org/wiki/Chirp_spread_spectrum}
Jameson: Had issues with exposing his router to the public, also with losing the session key.
NB infrastructure
Elan: Looking into [VS Code Server](https://code.visualstudio.com/docs/remote/vscode-server), wondering if it would be useful for the Python classes.
Other potential FOSS techs:

 * self-hosted k8s would require 
 * https://ceph.io/en/
 * Reliable k8s cluster - should have 3x

If we want to have a deeper LoRa conversation, Jameson would be happy to reach out to Joe Knapp (https://www.linkedin.com/in/joseph-knapp-a696568/) from Semtech, to come by for a technical dive.

Exponential backoffs? or Quadradic backoff. With jitter. Hosts backoff and try again.
