Building RC planes is a little harder IMO, but not much. The main difference in building planes is you have to pay attention to center-of-gravity much more; minute differences will make the difference between your plane flying amazingly, li

The most important thing about Denuvo is that it's on a subscription license to the game publishers, so it's almost always removed after some length of time. This is critical in understanding why it isn't cracked as often, be

Oh, I see how this works now! That's _incredibly_ clever, not at _all_ what I would have guessed, and quite innovative. Thank you so much for taking the time to post these explanations.

Right, that was my point about the physical layout not really being conducive to NN-driven stabilization, on my cursory read. Digging in, you could probably bitbang DShot on Orin GPIOs. It would be really sketchy since it's presumably

1) No, this is interesting specifically because it was all onboard, the drone has Jetson Orin NX on it. 2) No, the video the pilot sees is usually quite bad. Racing pilots usually use either HDZero (mid resolution video with weird pixel art

I saw that too - I'm assuming it means they're indeed using the DNN for stabilization. This has been done several times over the years, but generally with results which only rival PID and don't surpass it, so that's quit

This is quite cool since past efforts in this direction have usually relied on crutches like outside-in imaging and positioning. A few details I picked up: * The drones are a spec drone across the league. It's a fairly large-footprint

A link to the utilized library is not simply drive-by grump. I agree with a lot of complaints about non-substantive grouchiness on HN but I can’t be sold on this one.

I think that name policing and “the whole project is really just a wrapper for another thing” are dramatically different points of discussion.

It's just a thin wrapper for https://github.com/qasim/Airstream (I think it's very lame that the README doesn't mention this), which I think would work in a watchOS app although I'm not 100% sure it

Early 68030 Macs were probably closer; the X68000 had a ton of proprietary audio and video accelerators that made it very unique.

I agree with this. I also agree that there's no preferable situation. Apple have done a great job building mitigations and it shows in how difficult, expensive, and rare it is to fully exploit their platforms. I certainly wasn't i

I’m not sure I agree with the premise here, although I agree with the conclusion w.r.t Apple specifically. I’m 100% positive from experience doing VR in several non-iOS spaces that increased exploit value leads to fewer published public exp

This; "quality" is such an unclear term here. In an efficient market people buy things based on a value which in the case of software, is derived from overall fitness for use. "Quality" as a raw performance metric or a b

No, VLIW is even worse than this. Describing it as a compiler problem undersells the issue. VLIW is not tractable for a multitasking / multi tenant system due to cache residency issues. The compiler cannot efficiently schedule instruct
