I don't think that segmenting CAN wiring is a good solution to this problem. The Powertrain CAN will always be accessible externally for some definition of "externally" (on older GM cars it ran across the bottom of the car to

For what it's worth, most European cars have much more robust immobilizer systems that use actual cryptographic primitives to both obfuscate and authenticate start-release messages. This is for a variety of reasons - a legal and insura

I think the big issue is that this hypothetical car would still cost $30k-$40k before tax benefits. While I think plenty of buyers yearn for a "traditional" car, it's hard to justify one with the added base cost of electric.

When it comes to this kind of property, hotel brands like Ace are usually operators, not owners. VC is a thing in hospitality real estate too, and this is what a lot of real estate VC funds do. They'll buy a distressed property or loca

Presumably, OpenAI tell their partners and customers who are developing plugins that those plugins will be confidential and not accessible to end-users until they are released. This breaks that confidentiality.

I think it's both, take a look at the "status" field with states like "unreviewed" - there's some kind of submission process, and OpenAI curate what actually makes it to the "user market." This just b

It seems like Dreamworks had to move acceleration to GPU using CUDA and OptiX instead of SIMD/AVX and Embree - the released OpenMoonRay code supports both. It kind of feels like Dreamworks got burned a little by Intel here - they inves

This paper is the first place I've found a production use of Knights' Landing / Xeon Phi, the Intel massively-multicore Atom-with-AVX512 accelerator system, outside of HPC / science use cases. And for this use case, it m

There are a lot of different things called "Lidar" : at a minimum, Structured Light, Time of Flight, and triangulation are the three most common methods. Within each method, there are vastly different approaches - scanning vs. sin

You could just use two cameras, or even four, or eight cameras! Each with a different level of filter. Camera sensors are cheap. Degradation of the sensors on the "bright" cameras would be an issue, however.

For the record, I think this is a totally reasonable comment, and I don't see why it's being downvoted. Often, the same people who spread FUD about shell script installers will download a binary from GitHub releases, npm, etc. wit

There was also DVStreamer for Windows and other tools for other platforms which would store data on MiniDV tapes. This is of course a bit less interesting than storage to VHS, since MiniDV was already storing a bitstream, but still a clever

I think they're referring to gasoline "small" boats, like Mercury Marine type stuff, rather than full-sized ships, which generally use industrial / "stationary" diesel engines. I think the point still stands th

I think the worst anti-pattern is the "soft return to work" pattern that's sprung up, where one cohort of people have met and work together in person while the rest remain distributed and have never met. I think that "pa

Of course remote work existed before 2019, but there are also an enormous wealth of statistics indicating that it was not very common. On the flip side, some Hacker News users assume that because they had an extremely rare remote job before

To what extent are these used for this use case vs. very inexpensive laptop computers or Chromebooks? In most of my travels I've seen a lot more extremely cheap laptops than ARM SBCs. I agree that there's a stronger justification

I also don't get people who use these for desktops or especially homelab servers. It's never made sense to me. But, I really like them for "computer that's a computer rather than a microcontroller, but closer to the Real

I'm glad that the weird fad/craze of ARM SBCs used with full-size-class peripherals for Linux server/desktop workload tasks is finally winding down. To me, the beauty of the Pi and other SBCs is GPIO/SPI/I2C - you h

I used to work in very large Ruby codebases, and have also worked in some midsized Python ones. If you rely heavily on your IDE, these languages will be painful. Rubymine is surprisingly good for what it is, but it's solving an intract

In the case of Tiny Tapeout, it's unlikely you'd be replacing any kind of general purpose compute task. The process node and size of the ASIC just isn't really sufficient. It's a toy to demystify the ASIC design process.

This isn't the case at Netflix, who famously offer cash salaries and an option to elect to forego some salary in exchange for options. There are no RSUs at Netflix. Also, RSU+cash salaries are almost universally quoted in year-of Total
