It's fair, but they've been working on improving the quality of their officers since 1904.

Don't know if you were attempting to make a joke, but Stalin purged the army of older, most qualified officers in the late 1930s, because they came from the pre-revolution times and were viewed as a loyalty risk. One of his biggest blunders that severely disadvantaged the country when the WW2 started.

Many white-era officers did serve in the Red Army; including Zhukov and his ex-boss Rokossovskij. Being a cadre in pre-revolution times wasn't the issue itself; willingness to sabotage their own country was.

Incidentally, the blunder in the 1941 in the Red Army was an issue of loyalty indeed. Navy didn't experience the same problem.

Both fortunately and unfortunately that's not how sound works. If the drones are far enough away from each other that you don't get interference between them soundwise it doesn't matter if there are more of them. But if they do then two quiet ones may re-inforce to the point that they sound much worse than a single larger one.

Are you saying that sound conduction doesn't behave linearly?

Wikipedia is actually a pretty good source for this [0]. tl;dr it's not as simple as one drone makes X noise, so 2 drones make 2x noise. For that to happen, the drones need to be making noise at the same frequency and be perfectly in phase. Also, if they were perfectly out of phase, they could cancel the noise from each other out (this is how noise cancelling headphones work).

I've had the original Mini since it came out. Other than damaging a prop from it hitting a blade of grass on landing it is in perfect shape. Yes, they are so fragile I landed very smoothly in the grass and soft grass is enough to damage the props! I don't fly it as much as I used to. These new ones are certainly an engineering marvel with how much they have added and still kept it under 249g. The big one to me though…

I have a friend that builds his own drones (and RC vehicles, like a really big, fast tank). He sneers at DJI, but keeps one to entertain the mensch (that's me). He also sneers at licensing, jailbreaking, geofencing, etc. I notice that there aren't any pictures that actually show people in close proximity to the drone. The "drone in hand" picture looks photoshopped, so I assume the drone is actually not-so-mini. I hav…

Hmm… it’s interesting, the reaction I got to this personal anecdote.

It is what it is. This chap exists, and I talk to him, almost every day. He has a great deal of enthusiasm, and does interesting work. I am sure his approach is quite common, in the HN crowd.

My friend is not your typical DJI customer, and his approach is no threat to them. People like him have always been around. It’s like people that mod cars. They don’t threaten the mainstream.

But the reaction seems to have been quite defensive.

I had the same thought seeing the hero videos on this page displaying beautiful mountain scapes and vistas - I wouldn't want to be the person disturbing this space with an intrusive drone.

Others might say that drones are a sensible and respectful way to honor a beautiful landscape. Mini 2's are quiet enough and much of the hostility against their use is rooted in prejudice and a little bit of hysteria.

From a human's perspective maybe, from bird's though, not.

Light drones are great, but how far away are we from quiet consumer drones? I'd love to not have every hike ruined by some wannabe videographer.

At least then you know that you are being watched and recorded by some creep with a drone. It is disturbing how society tolerates these pretty-secret surveillance devices just because they can take videos that look like those documentaries on TV, yay...

I'd like to find a good competitor too, and not just because of the geofencing. DJI has been identified as a national security threat by the US DOD, essentially because there's no way to be sure that every second of GPS-tagged video shot by a DJI drone isn't going into a giant server farm owned by the Chinese intelligence service. https://www.defense.gov/News/Releases/Release/Article/270608...

That release is about using DJI drones in government and military installations. There is not a suggestion that DJI is being used to do wide spread civilian spying. Meanwhile in the US...

No because DJI, XPENG, BYD, and a ton of other Chinese companies have this 'move fast and break things' mentality X100 that most American firms don't have. They ran circles around GoPro and their attempts. Closest analog is Tesla/SpaceX but who knows if even those guys last long term when the guy running it is so easily distracted by nonsense (eg. Buying Twitter, starting yet another company, playing hours of Polytop…

Come on. American software startups literally invented that motto. Just because you may be working at a slower paced company doesn't mean America does not have it.

They invented the motto for BS social apps and pivoting until they're bought or IPOed.

Not the same as hardware at all.

The Silicon Valley has a long tradition of "move fast and break things". No no no, this time, it's just that the Chinese companies are simply a lot better than the Western drone companies. Yes, there are many excuses to make ("it…

>Respectfully, that's ridiculous. The Silicon Valley has a long tradition of "move fast and break things".

The SV doesn't do hardware for the most part, and any companies (SV or not) that do hardware, don't iterate that way and that fast. Watching GoPro evolve is like watching molasses.

Something like Tesla would be one of a few of counter-examples...
