Are you asking about BEAM or Go? Preemption already works in BEAM and doesn't lead to race conditions because of nothing shared concurrency.

Dirty schedulers can help with long running NIFs, but they can't help with e.g. a segfault in a NIF taking down the entire system.

Precisely, which is why I always advise to consider ports first :-) However, in some situations the overhead of communicating with a port might be too large, so then you have two options: 1. Move more code to another language which you

Thanks, nice to hear that! Basically a NIF blocks the scheduler, so if you run a tight loop for a long time, there will be no preemption. Therefore, invoking foo(), where a foo is a NIF which runs for say 10 seconds, means a single process

It is possible to start external processes from BEAM and interact with them. I've blogged a bit about it at http://theerlangelist.com/article/outside_elixir You can also write NIFs (native implemented functions) w

The atom always means the same thing - a symbolic (named) constant. The dot operator can be used on an atom type to invoke a function from the corresponding module. A capital Foo.Bar is called an alias in Elixir, and it's the same as a

I like to say that in NIFs (and port drivers) all the bets are off anyway, most notably process isolation and fault-tolerance. The guarantees such as "preemption" and fault-tolerance happen in the layer above (i.e. pure Erlang), a

I like to think of it as preemptive because (putting NIFs aside) it's not possible for a single process to completely block the entire scheduler, even if it ends up in an infinite CPU bound loop. So in other words, a task (i.e. process

I've been doing full-time Erlang for five years, and I personally prefer Elixir. Elixir is semantically close to Erlang the language, and allows you to take advantage of all the great benefits of Erlang/OTP. It's benefit is d

Everything is possible in a Turing complete language (assuming enough of base utility functions are provided by stdlib), so the question is not possible vs impossible, but how much of a help the tool is. Erlang provides great abstractions f

I guess JVM or .NET preference is often caused by inertia, ignorance or fear of change. In the company I used to work for, they had religious devotion to Microsoft. Everything that didn't come from MS was frowned upon, not only open source

I have more than 10 years of professional experience using C++, C# and Ruby to develop "classical" business web and desktop apps. I started using Erlang two years ago to implement a push server, and fell in love with it immediately. The lan
