No. I don’t know where this oft-repeated semiconductor meme came from, but it’s a really poor take. ASML are solving a small subset of physics problems: how to project extremely small features. TSMC are solving many more physics problems: h

It looks like they correctly isolated the safety critical components on the instrument cluster and they are still functional without infotainment: https://twitter.com/RivianSoftware/status/172443804967573962...

I strongly doubt this is the main reason. I think it's simpler and just like most hardware: there's no perception that open source adds value, and re-negotiating IP agreements with hundreds of sub-vendors would be unreasonably exp

The biggest excuse is much more reasonable (albeit annoying, the same reason why most board support firmware isn't open source): ECUs are built using code generation from models (ASCET, LabView/Simulink, etc.) on top of 10 layers

I think the point is to get Europeans to travel to Las Vegas. So having the strip lit up and the casinos visible is essential.

Why do I think these features are not nefarious? * There's an obvious, legitimate want for the vehicle's head unit to ingest this data, in order to display a UI (or provide a voice UI) which allows the user to call a contact by na

For what it's worth, in the iOS Bluetooth settings, "Show Notifications" is code for Message Access Protocol and "Sync Contacts" is code for Phone Book Access Protocol. It would be nice if they'd add an extra &

The module should go to sleep, and the battery management should also load-shed it if it detects the battery draining. I suspect this is probably not implemented correctly on some cars (because what is), but it's definitely something t

The easiest way to do this is usually to unplug the antenna and replace it with an RF terminator. The vehicle will simply think it is always out of range of cellular service. Unfortunately most modern vehicles require a lot of finagling to

You can disable Sync Contacts (PBAP) and Notify Messages (MAP), and then the Bluetooth head unit won't download your contacts or messages.

This rumor was completely false, of course. The reality of GameCube discs is that they were standard mini DVDs, but they used a slightly different physical frame layout and a different scrambling seed from standard DVDs, so consumer DVD dri

Hashed perceptron branch prediction is pretty much industry standard and has been since the 2010s (it arrived in academia around 2000 and in AMD Piledriver in 2012), it’s just up to marketing whether it’s a “neural network” or not.

The same exploit is present in the 8940, but the path to get there is slightly different and incompatible with normal PC host USB controllers due to the need to avoid ever sending a zero length packet. There are plenty of ports using low le

Autel drones tend to fall around a generation behind DJI's in terms of capability, and they don't have geofencing. Unfortunately, they are much more expensive like-for-like and if you are also concerned about China, they share t

One easy (albeit a little costly) solution here is to use the DJI Android-tablet remote (DJI RC / RC 2).

Yes, it is extremely annoying. Since there isn't a lot of competition left in the prosumer space, DJI are shifting their autonomy SDK features upmarket into their "Enterprise" series drones. But! There are workarounds. You ca

There is nothing that comes close to DJI for a flying camera, and I don't say this as a fanboy but rather as someone who has been in this industry in various capacities for a long time. Ardupilot and PX4 are great projects, but they&#x

Yes, 100%. In places where they get software residuals (agriculture and enterprise, via FlightHub and other services), development is constant because a team stays assigned to it. I do think that in recent years DJI have gotten way better a
