It's been 10+ years since cars have gotten screwed in the Consumer Reports and other outlets for bad infotainment. What's the fix? VW's MIB2/MIB2.5 was pretty much the pinnacle of automotive head unit innovation, IMHO, a

I'm not aware of any state law that prohibits a hushable smoke alarm. Short-term (<15minute, repeatable) hush modes are considered a safety feature. They prevent angry homeowners from removing the smoke alarm entirely, a far more da

Yes, a full replacement absolutely makes sense in this situation! I don't think there are many Windows infotainment units left these days. Analyzing the binaries to figure out the meaning of the CAN traffic is an awesome (and underutil

That's pretty cool! I wonder how properly they were really signed - there are _so many_ mistakes even in systems that at least don't use an example key off the Internet. The most common ones I know of are: * Out-of-bounds write is

Yep - the Switch had an issue in the mask ROM / first stage bootloader too, but it was a traditional software one, where the recovery mode bootloader passed an unverified length to a memcpy and smashed the stack.

iAPX 432 was sort of a different failure from i860 and Itanium, no? My understanding is that the issue with iAPX 432 was that the architecture provided object-oriented instructions, but they turned out to be slow in practice, and the compil

It's entirely different. Right now Starlink is a bent pipe model. The customer's station connects to a satellite which relays data to the closest ground station. Therefore, the satellite must be in contact with both the customer s

I just cut the Ethernet cable and put RJ45 on it, I wasn't about to drill another hole in the wall of my house to accommodate the connector. It works fine, even though I'm sure it's out of spec. There's really no good ex

That's been my experience too. Here in Colorado my service is actually pretty good - I get 20-30mbit during crowded times, and 150-200mbit during off hours. Outages were problematic a few months ago but have improved and now usually co

Starlink right now is a bent pipe between the dishy and a ground station. Depending on how many customers they have in a specific ground station's cell, they need different backhaul capacity for that cell. So, in the case of Starlink,

Good pointers indeed - Apple's code signing tool is open source, but heavily dependent on Cocoa/OSX libraries like CoreFoundation. I'm not sure if it works with any of the open-source reimplementations of these libraries, alt

IIRC the "Apicula" project for yosys/nextpnr support for Gowin FPGAs is pretty good, but still lacks a few key features for many designs - most importantly, Block RAM, but also PLLs and I think serdes/transceivers? I hav

Absolutely, and for the "full" FMVSS this makes sense - the stakes are high and the rules are a byzantine mess in a lot of areas (for example, making sure specific warning lights aren't obscured at each possible angle of a te

Self-built cars are usually a completely different process, and also don't involve import. But, the author of the article also massively overstates the requirements for a legal vehicle under the Low Speed Vehicle rules. The full FMVSS

It's just not true - the author of this article doesn't understand FMVSS or the process. How this works is basically: 1) There are safety guidelines (FMVSS) governing classes of motor vehicles. For LSVs, the regulations are _extre

The author of this article does not understand FMVSS or DOT regulations. 1) Yes, this is true, for several years the FMVSS has required backup cameras for full speed cars. However, this isn't true for low speed vehicles. 2) This just i

Why _would_ you expect anything different to happen at a massive company? It's not like the team who write the drivers are likely to know of the team working on optimizing compilers, profilers, or anything at all really. My experience

The N64 flash cartridge feeds data to the N64 on a 16 bit parallel bus. It's used to store the game ROM. I suppose by writing clever self-modifying "ROM" code, you could hack the Pi into acting as a coprocessor, but in this c

As we know, processors run a series of instructions, things like "move data," "add," "store data." Over time, these instructions have gotten more and more complicated. Now there are "instructions" lik

The patent mentions this system a few times, and it sounds like they moved away from this model due to mainly cost/benefit and scale up reasons. Laser pico projectors are certainly an easy way to do this, they're literally just a
