> Not sure if that's still a concern with modern ones? No, that's not really a concern currently, and I actually never heard that in combination with LTO - which is relatively modern.

I mean, it's a one time investment that's may be good for a decade or so, depending on the setup and workloads. But yes, forking over a 2 to 4k for a new LTO-7+ changer isn't a small investment for private use, for a company

ACME is a standardized protocol (RFC8555) and there are more providers than Let's Encrypt, and you can switch transparently. That combined with the standard procedure of renewing a few weeks before the expiration date lets one handle e

I made a simplified MIPS (no FPU, 4-stages pipeline with a basic interrupt controller and nothing out of order or the like) in VHDL for a uni course. We had some simpler exercises before that (e.g., PS2 keyboard controller) and with that I

And people also ride motorbikes in bike lanes, even cars sometimes - so what's your point? Legal ebikes won't make this more dangerous, and people doing illegal stuff are always more likely to not care and endanger people.

They do help, hard realtime only means that there can be no blocking (critical) section with a possible unbound time limit, toggling an IO register with a lower frequency as the CPu clock can still be done while shovelling in datagrams into

And ESP's rust support provides threads and async supprot nonetheless. With a zero-cost async implementation you may not require multiple cores, for some hard realtime stuff maybe, but even that can be handled by the work scheduler.
