RC stuff (ELRS, Crossfire, etc.) like the parent post mentions mostly avoids this issue by also using FHSS.

Concentric-shaft wet DCTs aren't bad - for example, replacing the clutch pack on a VW DQ250 is very similar to replacing the torque converter on an automatic. You have to drain it but it's not particularly involved. There's b

I've never really seen retention risk tooling used for evil in the way that most HN readers seem to think it is; it's kind of interesting and eye-opening to me to see the strong negative sentiment towards it. I've worked in m

I don't really think so; what's in dispute isn't the bytecode translation, it's locking the higher-level library IP to hardware. This would be like Google saying "you can only run our Android applications on a Googl

That's literally what they're doing. HIP supports Nvidia as a backend, and AMD are making replacements like MIOpen, which is intended as a quick-port replacement for cuDNN.

I think they're betting that as NVIDIA hardware gets more expensive and harder to get, especially in the datacenter, there's now an opportunity to entice developers to take on the pain of porting to HIP/ROCm. Nobody cares abo

by bri3d 3y ago
HIP/ROCm is the direct equivalent to CUDA (with MiOpen as the cuDNN equivalent). It's actually Not Bad, although it is pretty AMD-typically buggy.

This isn't NV saying "you can't make ZLUDA," it's NV saying "you can't run our libraries like cuDNN, cuBLAS, cuBN on non-NV hardware." While this kind of restriction still isn't legally cut and d

I don't really think this was in AMD's best interest when you think about it strategically. Unless it were production-grade and legally tested, it's basically a tool that would enable developers to build applications using AM

They'd be starting from scratch, so it would be way too large an undertaking. Automatic tracking of any kind in drones is still not a commodity; most DIY FPV drones like these use flight control software which is ridiculously primitive

HexWalk is much simpler than ImHex. It uses Qt so the GUI is more native (ImHex, of course, uses Dear ImGui). HexWalk is much more "fixed function" than ImHex. ImHex is basically a core hex editor view with a canvas you can fill w

Are you not familiar with out of process COM servers? A lot of Office automation is out of process, even inside of Office itself. Admittedly I’m not sure about the grammar checker specifically. As for the Spellcheck API, external providers

Funny choice of example. You’ve always been able to use Word as a remote spellchecker over COM, and as of Windows 8, spellchecking is available system wide and runs in a separate process (again over COM) for sandboxing reasons. JSON over TC

Intel ME allows intentional remote access through the ME in some enterprise scenarios (vPro). The driver support matrix is quite small and this is a massively overblown concern IMO, but it’s the root of a lot of the hand wringing. However,

The base cost of an electric car is very high, so customers (at least, according to manufacturers), demand features aligned with the price. A $25-$30,000 ICE work truck or $20,000 basic economy car looks good compared to the feature laden $

Hmm. I also thought the type confusion in 518 was the same one from the blog post, but looking at the patch, it's not either. I think I stand corrected overall.
