Inter-node mesh with raw Wireguard is an exercise in patience to say the least; I have a few different colo sites, my house, my phone, LTE/5G hotspots, raspberry pi projects in the field, etc that I want to fully connect together. Raw

"Rarity" is a distinction without merit in this particular case; the important thing to note is that (most) clouds don't guarantee _any_ availability of a single zone. A system which stashes all of its infrastructure in one z

Seeing this, I had the initial idea of using AdGuard logs to trigger a power-down of your device if you try and visit brainrot content. I think I like it that way more.

Yes, that's my family's business, I'm glad to hear you've had such great experiences. Similar to you, I've never looked back; every time I put on trail shoes I yearn for my boots again.

$200 is enough to get you a pair of Keen boots, which will last a year or two. Truly "good" in the boot world is hand welted hand made leather boots, which are a rarity these days. There are functionally only a few bootmakers that

Oh hey I'm uniquely positioned to answer this; though I'm in tech (and at this point frankly speaking well-compensated) my family have been bootmakers for decades. I'm sitting at a tech office right now wearing a pair of boot

It wasn't a 30dBi antenna for the control link, but a light moxon with 5.98dBi according to its datasheet. Standard 5.8GHz analog video, on the other hand, did require a ton of gain.

LoRa is just a protocol, there are no rules inherent to the protocol itself. Certain LoRaWAN networks have rules around how often you can send messages through them, but RC links don't use LoRaWAN.

In particular, people used to plain FSK RC protocols like Spektrum DSM, FrSky D8, Futaba FASST, and similar which tend to failsafe around <1km even with 100mW of power believed that a 2.4GHz link could never do 100km regardless of interf

Notably, Wez's flight was done with 2.4GHz LoRa (this was one of his main points, to address naysayers who claimed a 2.4GHz link could never achieve >100km) while Charles is using 900MHz - the same setup that achieved 100km (100mW w

Quite well. I wrote a blog post about this a few years back: https://frank.petril.li/posts/dialup-adventures-1/

Unfortunately the latency is nowhere near good enough for racing - best case actual results are ~100ms E2E. The project authors have claimed some absurdly low latency numbers in the past but they're laden with asterisks, like using a w

GPS on its own especially with systems like WAAS is quite accurate these days, generally within a few meters. If you need more (which planting most crops does) there's also RTK [1], which permits centimeter-level accuracy from relative

Good question - it's been almost two years since this project so I don't recall whether V.92 came up at all, even on a pure T-1 setup. I still have all the gear, if I set it up and run it again I'll update this thread.

Ahaha yeah it bugged the hell out of me too. Near as I can tell, there's nothing wrong with the Open5GS S1AP message, so filing a GitHub issue isn't the way forward. I did speak with Baicells about it, but their response was sorta

I thought I was the only one silly enough to do something like this! I've got a Nova 227 tucked away in a corner room of my home facing inwards connected to Magma (was Open5GS). Did you run into the bug where the default Open5GS bearer

I've worked in these types of organizations before, and it's always counter-productive to making positive changes in the environment. You as an SRE can either make it better, or find an environment that's conducive to positiv

I ended up writing a CLI to do it that's relatively full-featured. At some point, I intend to move functionality to a shared library between a CLI and a Web frontend, but for now, the CLI works tremendously well for my use cases: http
