Since yesterday, diskless hosts (i)PXE-boot #NomadOS over the Internet from TFTP- and HTTP/S Anycast servers on @flydotio.
The new #Terraform Provider for Fly.io facilitates building CI/CD pipelines on TF Cloud of the inverted #HashiStack and its DNS integration.
Just published a tiny "Distroless" TFTP server written in Go that builds, deploys, and runs on Fly.io's public cloud Anycast network community.fly.io/t/flygotftp… github.com/hb9cwp/flyGoTFTP/…

Got TFTP and static HTTPS servers written in Go to work on @flydotio Anycast network which supports UDP (not for IPv6 yet). They hand out customized iPXE and #NomadOS images to devices using PXE network boot. Summary of my experiment's "Use Case" community.fly.io/t/ipv6-udp/…
Experimenting with @flydotio's global IPv4/6 Anycast cluster as build hosts for serverless WebAssembly functions written in Go, and as static HTTPS servers for secure PXE/iPXE network booth of #NomadOS. community.fly.io/t/wasm-runt…
With #NomadOS, we turn #HashiCorp's "Cloud Operating Model" upside-down. #Nomad becomes a solid foundation for Applied Zero Trust using an inverted #HashiStack. It is more versatile than Kubernetes, but less complex! github.com/jboero/nomados
See @YellsOld showing #NomadOS in action. Thanks John for your hard work and support! nitter.gq/HashiCorp/status/15048…
As an experiment, HashiCorp Solutions Engineer John Boero tried to make a Linux distribution out of HashiCorp #Nomad to see if it was possible to run Nomad as process ID 1. He shares the insightful results in this #HashiTalks recording. hashi.co/3InAONh
Finally, got immutable NomadOS/HashiOS to network boot also on bare metal servers using PXE.
Now, trying to cast everything into Pull Requests for repeatable builds with Linux and OpenBSD kernel images for tiny and large targets. medium.com/hashicorp-enginee…
Even if you are not into OCaml, MirageOS, or Unikernels, you may still enjoy listening to @avsm about his great career among OpenBSD, Xen hypervisors and Cloud, Docker, and building software systems that are power-efficient, reliable, safe, and scale :-) signalsandthreads.com/what-i…
See here why operators of radio transmitters are called "sparks": VVV DE SAQ on 17.200 kHz this Xmas Eve morning youtube.com/watch?v=Ecg2UrKv…

Received my "Hermes Lite 2" Software Defined Radio (SDN) HF transceiver kit some two weeks ago. Since, SparkSDR logs dozens of low-power WSPR beacons a day from all over Europe and overseas on 80, 40, 20 and 15 m bands just using a 5 m wire antenna.
With pleasure I discover that my experiments from 3 years ago with OCaml/MirageOS unikernels and Solo5-hvt as tender now build and run very well in vmm on OpenBSD-6.9 :-)
Taking a deep dive into Go dev & debugging while trying to get "Boundary" to work on OpenBSD like the other tools from the "HashStack", with great support from devs at HashiCorp :-)

This video from 1979 shows telecoms of the International Committee of the Red Cross (ICRC) via HF radio which I encountered as a young engineerint student when I left Switzerland for my first assignment to Sub-Saharan Africa in 1984. avarchives.icrc.org/Film/51
Migrated my DNS Firewall with RPZ experiments from Bind9 on pfSense/FreeBSD to PowerDNS Recursor on OpenBSD. Gives me scripting in Lua and log exports using Protobuf, which facilitate mitigation (user info via Landing Pages, Walled Gardens).

Threat hunting on-a-shoe-string in the WLAN of a coworking space using DNS Firewall home-made with Bind9 and Reverse Policy Zone (RPZ) feeds on pfSense (FreeBSD).
The Helium project claims it's modulation and protocols will be "open", unlike Semtech's LoRaWAN Alliance. Still, their LongFi/WHIP appears to use LoRa PHY!? Reportedly they raised 51 MUSD to start and build their network in the US. helium.com/

Sensor data from my portable lab LoRaWAN node arriving in AWS IoT is now includes precise time stamp, position vectors, and GPS parameters. Now, let's try some Machine Learning for simple weather prediction!

Dead on arrival was my 5$ GPS module from China. After resoldering the u-Blox knock-off MCM over cooking plate, it does work in my Mbed-OS LoRaWAN node :-) Challenged my eyes and abilities as hardware maker!
