Is the cookie not associated to a specific IP? SSO systems would normally flag the mismatch if you try to connect to a website and pass an SSO cookie issued for a different IP, so sniffing cookies wouldn’t help all that much.

There's lots of factors: * GC: it probably had a very simple algorithm, rather than a fancy generational GC * Data structures: it wouldn't support modern functional structures like HAMT * Compilation: you probably used an interpre

You can build every actor like a miniature program, with its own imperative shell and functional core. In Erlang it's common to have various message handlers that are very imperative, but defer all complicated logic to pure functions t

The functional core can return a symbolic description of actions to take, which the shell executes, a bit like a simple interpreter. This is a good example: https://www.theerlangelist.com/article/spawn_or_not (Note the

I've done many of these things, documenting the arguments, evangelizing and building up enthusiasm in my team (I didn't write the Elixir system alone), etc. but was still told by our lead engineer and technical managers not to use

What do you do after the experiment is done? I’ve been through that already for a relatively minor project and been asked not to do it again, even though the project worked out very well. The problem is we end up with something that can’t b

After three years of trying to push for adoption, I’m also starting to find it depressing. I’ve talked with various people also looking to introduce Elixir or Clojure in my workplace (large company), and even when it’s a perfect fit for the

Erlang iolists are an example. It means you can generate HTML from templates as a deeply nested list of strings, and write that to a socket efficiently, without concatenating the strings.

No, messages that don’t match are not dequeued in the first place. I don’t know why the other poster used the word discard.

You can put a bound on the number of actors under a given supervisor. That being said the main reason an Erlang program will use an actor per request is not to prevent overload, it’s for fault tolerance; in your a -> b -> c -> d ex

I think it’s just a bit badly worded. You don’t normally throw them away, you leave them in the queue for later. For instance if you have a process that gets requests and writes stuff to DB, while processing a request you can send a message

Out of curiosity, what pushed your team towards Pony rather than Erlang? It seems your team (or at least part of it) has experience with both languages which is interesting.

That’s quite possible. The GC has changed several times. There was even a unified heap fork of Erlang at some point: https://www.researchgate.net/profile/Marc_Feeley/publication...

You can do these tests against a UAT environment. It doesn't have to run on your own box. In my apps I use fakes in dev and test mode, which makes development very fast and easy. A few tests run against the actual UAT environment, but

I don’t think it’s Riak. It just uses riak_core, which is a kind of distribution / sharding framework. Riak itself has new owners and is not going away.
