I think you’re aware of this already but for everyone else: There’s different kinds of embedded. What traditionally was referred to as embedded is microcontrollers (e.g., 32-bit ARM Cortex M devices like the STM32 or an NXP IMX106x chip ).

+1 for this. On my system, an ARM cortex-M7, there’s RAM at address 0. In order to catch null pointer dereferences I ended up activating the MPU to make the first couple hundred bytes inaccessible (non-readable, non-writable).

Perhaps they’re conflating how you can’t use “const” as a compile time constant (e.g., you can’t declare the size of an array with a “const” variable). If so, C23 solves this by finally getting the constexpr keyword from c++

Agreed. As an embedded software engineer new to the field I’ve seen senior engineers with over ten years of experience complain when division by a compile time constant (even by a power of two) is used in code instead of multiplication or b

Such needless condescension, jibal.

I was just at one of their offices in San Francisco. They have free breakfast, lunch, and dinner with choices from well over 10 whole restaurants exclusively on their campus. They have (paid) laundry service where they can just drop off the

FWIW you can go to settings on GitHub and select what you get emails about. There may even be a digest option such that you get one email per day with all the stuff you would’ve received individual emails about IIRC.

Luckily we can protest Tesla and spacex (via not signing up for star link) at the same time.

Because this follows what the Associated Press style guide suggests and it’s either in enough of the training data to be followed, or, OpenAI purposefully made it follow a style guide that happened to contain this rule after the fact when g

Could you please expand on how that is murder?

> If you want a processor that works this way, buy a microcontroller. The ARM Cortex-R5F and Cortex-M7, to name a few, have branch predictors as well, for what it’s worth ;)

My understanding is that the cost that is mentioned comes from the branch introduced by checking if the dereference is in-bounds (and the optimizations these checks allegedly prohibit), not from what happens if an OOB access is detected
