as someone who works 95% of the time in rust, how to handle my errors is never a problem for me. I think the issue is the expectations of people coming into it with a different frame of reference, expecting the kind of traceback/except

I completely agree you can build hardy solar/wind generation (i.e. runs in winter), however, the sun still sets each day, and wind is intermittent and unpredictable. until there is a revolution in battery technology, relying on those t

I read the section in that book about storing each thread's count in a TLS variable, and I think the root of the confusion is related to how C vs. Rust (the language I use and learned how to write multithreaded code in) deal with threa

first, I don't understand how this quote squares with your overall description -- it's specific, first-hand, from a named source, who should (on its face) know what he is talking about: > “This was espionage on the board itself

we must have read different articles. I read one where multiple credible people went on the record to say the FBI had warned them that supermicro servers were compromised.

I have done plenty with threads but never used thread-local storage except when forced to by some other library using it. To me it seems like a bolted-on monstrosity that provides thread safety to thread-naive code after the fact. Am I miss

in rust, there is no built-in runtime, so it depends on which one you are using. the runtime (e.g. tokio) is responsible for polling the future. for network io, behind the scenes this is most likely utilizing epoll system calls. epoll mitig

generally speaking, the advantage of async io is strongest for high performance server applications, especially in regards to the cpu usage required relative to the amount of io stuff you can do. with that in mind, "users running your

mio and mio_httpc are options if you're the kind of person like me who finds 'async' worse than event loops.

do you have any sense for how this would integrate with rust? as someone who isn't familiar with how it works, it's not clear whether that would be as easy as normal C ffi interop or more involved.

for long-running daemon/server programs where reliability is a key priority, I have had a lot of success building in "partial" restarts into the design, which means that periodically the program exits the main event loop and
