This answer is flat out wrong. Using an individual DDR4 chip (not a DIMM) as an example, the addressing scheme is composed of 18 row bits, 10 column bits, and 4 bank bits yielding a maximum address space of 2^32, or 4,294,967,296 bytes, or 4GiB per chip. Previous versions of DDR had fewer row bits and fewer banks, but DDR has always been designed so that the maximum size is a power of 2.

woopsies

@RоryMcCune Or the other roro can vacation at NY and get his own bottle :P

In fact generally speaking usually the most fun things are also the most dangerous

What just because it's easy to blow your arm off doesn't mean grenades aren't fun

@CodesInChaos What's your beef with C?

@Gilles Direct Message.

@schroeder DM incoming

You know what I mean.

conscience? or something.

Nah, my conscious wouldn't let me

@Gilles Because reasons.

@Gilles o

@CodesInChaos You just got a (probably) strange email invite. Accept it.

Yup, followed

@SEJPM def wanna dm your email

@SEJPM #WorksForMe

@SEJPM AFAIK yes

Yes it should!

@ThomasPornin delete! :)

@ThomasPornin shhhhhhhh

Trust.

@SEJPM It's for a good reason

@RoryAlsop AFAIK

With the way they were hyping it, you'd think there'd be at least one RCE

@RoryAlsop It's a DoS + MiTM vuln

So no, not serious

The issue is that the relays will have small, low power coils in them that might be easy for a sufficiently large EMP to short out indefinitely. To top it off, most of those relays are completely sealed, so fixing them might be quite a pain

Yeah everything that relays would control in an older model vehicle like that

As for the relays (which also have small coils), there might be something there.

@DucatiKiller Yup, but like I said, those coils are meant to handle gobs of power to start the engine, so should be no worries.

In which case you could disassemble the alternator and repair the coil with rubber cement or something like that.

i.e. if it caused an arc between two windings in a coil it wouldn't put it out of service completely

Also, even if an EMP was able to pierce the coating on the wires in an alternator, the alternator would still work it would probably just spark like crazy

@Pᴀᴜʟsᴛᴇʀ2 Yeah, or stop indefinitely

@DucatiKiller Semiconductors

@DucatiKiller If there is an EMP large enough to kill a coil that's designed to withstand 100s of Amps of inrush current, you've got bigger issues

The reason why an EMP is dangerous to discrete electronics is because the electromagnetic field will cause shorts and sparks insige the chips

Anything designed for an automotive environment is going to be extremely rugged

I would have to say yes

Basically all controls are done with automotive relays and switches?

i.e. ECU, sensors, etc

Your first concern in the car isn't going to be any coils, it will be the discrete electronics

@DucatiKiller What sort of coil?

ohai

@called2voyage Things are far from "settled", however there isn't any open hostility (Not that S ever was, really).

@Hohmannfan Yup, he's back to normal (well, normal for T anyway :P)

FYI I got in contact with T and everything is resolved. AFACT he's still not coming back, though.
