White House: Future Software Should Be Memory Safe (www.whitehouse.gov)

On the one side I really like c and c++ because they’re fun and have great performance; they don’t feel like your fighting the language and let me feel sort of creative in the way I do things(compared with something like Rust or Swift).

On the other hand, when weighing one’s feelings against the common good, I guess it’s not really a contest. Plus I suspect a lot of my annoyance with languages like rust stems from not being as familiar with the paradigm. What do you all think?

writing a high performance video game that can run on older hardware

Unless it's some really exotic platform, I'd honestly still say no. Rust has shown that memory safety and performance doesn't have to be a tradeoff. You can have both.

But sure, if whatever you're targeting doesn't have a Rust compiler, then of course you have no choice. But those are extremely rare cases these days I'd say.

I don't even think we really need to eek out every MHz or clock cycle of performance these days unless your shipping code for a space vehicle or something (But that's an entirely different beast)

We've got embedded devices shipping with 1GHz+ processors now

It's just time to move on from C/C++, but some people just can't seem to let go.

Battery life is a reason. I've had clients come to me complaining their solution from another vendor didn't last very long. Turns out it was running Java on an embedded device.

Why would java have an impact on battery performance ? Pretty much all credit cards run java for their encryption algorithms, and they need pretty much no power to run.

The JVM isn't free. It was a simple data collection device that interfaces with a sensor which ideally doesn't need maintenance as long as possible. Something light written in C is more than enough.

There are orders of magnitude in what is considered low current. I've worked on a product that was guaranteed 2 years of lifetime for 3 AA batteries.
