It's absolutely the case that if you are driven by "social context" (by that I mean, roughly, "other people's concerns") alone, you won't choose Erlang.<br>
<br>
Although I would often choose Erlang for myself, I would often choose another language if I had a programmer of that language to work with, and a tight deadline.<br>

In my opinion, professional software developers should choose the best tool for the job -- and the job often includes more than the problem at hand, true. I like to make satisfied customers.<div class=""><br>

Erlang makes efficient use of computing resources, specifically in distributed environments. It does several other clever things. It's also hard to learn (for some programmers) and doesn't come with a ready "market" of/for proficient software developers. But those who learn it tend to understand the problems which Erlang is good at solving. And they understand why the language choices made in Erlang might be made, in which case, they will often understand other languages better than average devlopers too.<div class="">

Ahh but here you are wrong. Java itself is analogous to Erlang<br>
without OTP. you don't HAVE to use the JDK libraries beyond<br>
java.lang. You would be a bit crazy reproducing the wheel if you<br>
did so but it is not a requirement of writing java. In fact many<br>
Java controlled micro devices only allow a very small subset of<br>
the JDK to be used. So there is essentially no difference.<br>
<br>
So Elang is to Java as the Java Development Kit is to the Open<br>
Telecom Platform. And there is where we have the "marketing"<br>
disconnect. Its not about changing functionality or a triviality<br>
to be scoffed over. If we start with the premise that we want more<br>
developers to learn and use Erlang then we have to consider how<br>
the language and its nomenclature comes across to our audience.<br>
You don't name a language the Scalable High Integration Technology<br>
because the impression it leaves with adopters is ... unfortunate.<br>
</div></div></blockquote><div><div class="h5">
<br>
Why start with that premise instead of starting with the premise<br>
that developers should try to understand what is useful to them?<br>
That has nothing to do with marketing, and everything to do with<br>
software developers understanding their craft better.<br>
<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
So if you DON'T care about people adopting the language, then the<br>
discussion is academic and simply, as one reply put it, a waste of<br>
time. Of course if you don't care about adoption then you are<br>
wasting your time here because you wont be able to staff a<br>
development crew, replace developers that leave or push the<br>
language into an organization which isn't currently using it.<br>
</blockquote>
<br>
Who is “you” in this case? Does the “Erlang community” want to get<br>
the language adopted more? Perhaps. Why would that matter to the<br>
Erlang community - how do they benefit? Why should those who already<br>
know and benefit from Erlang not simply continue to do so?<br>
<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
If you DO care about people adopting the language you have to<br>
consider its marketing. If I many were to take Erlang to<br>
management and propose it for a product the management would see<br>
"Open Telecom Platform", object that the company isn't a telecom<br>
company and that Erlang is mainly for telecom and that would be<br>
the end of that. In fact, if you really care about adoption you<br>
are better off renaming it "Fred" than leaving it as "Open Telecom<br>
Platform”.<br>
</blockquote>
<br>
People reject languages for all kinds of strange reasons. And it’s<br>
the case that in many cases you can simply choose “a language you<br>
like” and then *make* it work for what you want to do. After all,<br>
computers have particular resources available to them, and a<br>
language well-adapted to its environment should support adequate<br>
performance for most applications. The distinction between threading<br>
in Ruby and “event-driven” in Node is largely meaningless, for<br>
example. The real questions are things like “how well does your<br>
VM/compiler exploit computer hardware resources on the platform<br>
you’re using”. Most developers don’t understand this, so they argue<br>
about threads vs. processes vs. events without understanding what<br>
might actually be the critical differences regarding the performance<br>
they say they want.<br>
<br>
Naming won’t fix that. And management will never get that. You need<br>
people to understand what they are doing. Or not. After all, you can<br>
largely do what you like and apart from at the edges, it will likely<br>
work.<br>

That’s a *HUGE* difference. Erlang as a language is very<br>
small; OTP is a very complex piece of software, as is BEAM.<br>
The three shouldn’t be conflated.<br>

Java as a language is big and complex, because it has a lot of<br>
concepts directly inside the language.<br>
