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…

"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 whi…

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 a…

$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.…

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…

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 gai…

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 d…

In particular, people used to plain FSK RC protocols like Spektrum DSM, FrSky D8, Futaba FASST, and similar which tend to failsafe around Also notably, LoRa does tremendously well …

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 …

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 th…

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]…

https://frank.petril.li/posts/dialup-adventures-1/ explains it all!

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…

As an FPV Enthusiast, I suspect strongly that this is Orqa/ImmersionRC (which merged recently). > video headset for drone pilots ("FPV goggles", for those in the know) Orqa FPV.one…

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 wi…

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). Di…

Speaking from my perspective as a prolific FAANG interviewer: Listing whatever experience you can (high-school jobs, sites created for friends, college jobs) alongside interesting …

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 fi…

Sounds like something GCP support would love to help you troubleshoot. The disruptions I'm aware of have no correlation to load balancer traffic paths. What's the actual reason lis…

We're aware this happened - that posting is the responsibility of an adjacent team to my own, specifically the person right next to me. :)

Hey, awesome! I met the Windmill Eng team a few weeks ago at Kubecon in Seattle, awesome to see tilt here. It's definitely a young product, but it's a good start to exactly the exp…
