"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 zone only is expected to be impacted by issues with that cloud, while a multi-zone setup spanning a region is generally "soft-guaranteed" to be resilient to normal operations / failures.

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 still manufacture this way these days, and about half of them are all in the same Washington State region :)

Expect ~$400, and it's easy to spend $600 without much effort.

That said, look at my comment above in this thread; they do really last 10 years or more, so the investment is well worth it.

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 boots that my father made for me in 2015 - regardless, they're absolutely spotless and I'd wear them to a formal event without hesitation. Every 6 months or so when I'm by his store I shine them up and put in a fresh pair of leather laces. Every 3 or so years, he re-soles them when the soles eventually wear out and lose traction. Eventually they'll require a rebuild, but they've got probably another 5-10 years of daily wear in them before that. I've got a few more pairs I swap between every so often, like a pair with OD green canvas that looks nice with khakis, but these solid black ones are my daily wear.

While 10 years sounds like a good run for boots, my father has a pair at ~35 years old now that he still wears frequently. IIRC they've been through one or two rebuilds and few re-soles in that time.

Were these commodity sneakers, I'd be purchasing a new pair every few months. Even nice running or trail shoes only tend to last a few hundred miles in my experience, but I've put tens of thousands on these and will get ten thousand more easily. Re-soles and rebuilds aren't free, but they're less than a replacement and put years of lifetime back on the boot. They're also comfortable as hell and fit me like a glove.

So in short: yeah, rich men do wear the same pair of boots for 10 years, or even far longer.

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 interference or noise issues.

Also notably, LoRa does tremendously well with real-world noise and interference. Of course any receiver is susceptible to frontend overload, but in "normal" situations I never worry about flying 2.4GHz even in crowded cities, and have never had a failsafe even in some ridiculous situations. As someone above mentions, LTE on the 800MHz band with 900MHz control links are much more of a problem - I've had a failsafe for that exact reason at <200m total distance from takeoff.

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 with a lightly directional antenna on one end, ExpressLRS 50Hz RF mode) would have a theoretical range of >500km on 900MHz. LoRa at longer wavelengths can achieve some incredible feats - like microwatts or nanowatts of power to >1 mile as we saw here. :)

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 wired connection.
