Even with Go it's a fairly bad idea not to use Goroutine pools for request handling if you're writing low-latency services. You can get isomorphic results with a future pool and channels.

With 1.0, rust no longer has a runtime at all, so official support for libgreen was actually dropped. However, between sync::mpsc, sync::TaskPool and sync::Future you can produce similar results.

Many people seem to be confused by Rust's lack of limitations imposed on you as a programmer. In particular, the fact that so much of what is thought of as a runtime is provided as optional libraries. You can run tasks similar to Gor

You can create freestanding binaries, but you need to implement more things on your own. Check out this page for some interesting projects: https://github.com/rust-lang/rust/wiki/Operating-system-deve...

Feel free to use the asm! macro in rust when you need to. FFI support is also quite good.

Not quite, I am against the notion that everybody uses Go for one reason. But I also think that the reason you gave would not be true if goroutines and channels, or some other easy to use concurrency abstraction, were not a primary fixture

You are absolutely correct. I should say that the THEORETICAL performance of Rust may be competitive with C++, maybe even faster in some cases, but that work remains to be done to get it there. My above statement assumes that this day wil

Ted meant that Go has a decent story for this particular use case, not that everybody uses it because of that. I think that you meant to say "distant from my reality" instead of "distant from reality", because otherwise

I think what he meant is that the compiler gives you certain guarantees that in some cases will mean that you don't need to directly use atomics and mutexes at all. Rust still allows you to arbitrarily harm yourself, but it usually ma

This has indeed encouraged much comparison: there is simply a large overlap in the communities that may be inclined to use either. There was a discussion between the authors of C++, Rust, D, and Go in which the topic of what a "system

They are compared because as humans, we are much better at learning new things when contrasted to other things that we are aware of. A concept that has absolutely no parallels with a previously encountered one is much more difficult to und

This is so much more important than people are generally aware of. We are leaving the point in time that writing highly bug-prone C or C++ is justifiable due to performance concerns. The justifiability of these up until now is a huge reas

I don't know very much at all about objective C, but the way these things generally work is that you will benefit from the experience as you learn new languages, as it will be an anchor of context against which you may base fresh perce

Reading a book cover-to-cover is, for me, a bad way to learn a language. I usually pick things up very quickly when I try to implement things using them that I am both familiar with and faced with annoying issues stemming to the language t

cdb is immutable - when you want to change the contained data set you generally rebuild the file, flip a fs link to the new version, and release file descriptors referencing the old version in applications when it's time to move on. b

CDB is awesome for its use case - slow changing, read-heavy workflows that are tolerant of stale data. One limitation of the original implementation is the use of 32-bit keys for addressing, which limit the addressable size to 4gb. There
