explore a few languages
discuss why they're "next-generation"
do some speculation and futurism
... because all our mainstream languages are old
... because productivity gains with elevated abstractions
... because functional programming couldn't get out of its own way
Julia: dynamically-typed high-performance general-pupose
Crystal: statically-typed Ruby-esque general-purpose
Jolie: service-oriented
Wing: cloud-oriented
Wasp: full-stack web app
Mint: web-oriented
This is a "survey talk"
we want to cover a bunch of languages
in less than an hour
hello, here it is, goodbye
very happy to discuss any of these afterwards
The point here is "to know what you don't know"
... and give you some signposts for exploring
... and maybe give a talk at a future conference!
https://julialang.org/
compiled (via LLVM)
complex and rational numbers
object-oriented and functional via multiple dispatch
dynamically-typed
parallel, async, multithreaded processing
implicit distribution capabilities
metaprogramming (code is data is code)
Julia distributed invocations
$ julia -p 2
julia> r = remotecall(rand, 2, 2, 2)
Future(2, 1, 4, nothing)
julia> s = @spawnat 2 1 .+ fetch(r)
Future(2, 1, 5, nothing)
julia> fetch(s)
2×2 Array{Float64,2}:
1.18526 1.50912
1.16296 1.60607
With some interesting metaprogramming support
julia> ex1 = Meta.parse("1 + 1")
:(1 + 1)
julia> dump(ex1)
Expr
head: Symbol call
args: Array{Any}((3,))
1: Symbol +
2: Int64 1
3: Int64 1
julia> ex2 = Expr(:call, :+, 1, 1)
:(1 + 1)
julia> ex1 == ex2
true

Hello world
julia>
--project=dir: Set dir as the home project/environment
-p/--procs: Launches N additional local worker processes
--machine-file file: Run processes on hosts listed in file
type-inferencing helps keep syntax clean
metaprogramming (code as data)
strong math/science features/ecosystem
performance of native (LLVM)
interoperability across other LLVM-based platforms (GraalVM, etc)
clear embedding API--viable scripting engine

web playground: https://play.crystal-lang.org/#/cr
native compilation (via LLVM)
heavily Ruby-inspired syntax
statically type-checked, type-inferenced
non-nillable types (compile-time nil checks)
macro metaprogramming system
An HTTP server
require "http/server"
server = HTTP::Server.new do |context|
context.response.content_type = "text/plain"
context.response.print "Hello world! The time is #{Time.local}"
end
address = server.bind_tcp 8080

a service-oriented programming language
"it is designed to reason effectively about the key questions of (micro)service development, including the following:
What are the APIs exposed by services?
How can these APIs be accessed?
How are APIs implemented in terms of concurrency, communication, and computation?
built on top of the JVM
"More in general, Jolie brings a structured linguistic approach to the programming of services, including constructs for access endpoints, APIs with synchronous and asynchronous operations, communications, behavioural workflows, and multiparty sessions. Additionally, Jolie embraces that service and microservice systems are often heterogeneous and interoperability should be a first-class citizen: all data in Jolie is structured as trees that can be semi-automatically (most of the time fully automatically) converted from/to different data formats (JSON, XML, etc.) and communicated over a variety of protocols (HTTP, binary protocols, etc.). Jolie is an attempt at making the first language for microservices, in the sense that it provides primitives to deal directly with the programming of common concerns regarding microservices without relying on frameworks or external libraries."
Jolie requires Java 11+ to run
Download the Jolie installer
https://www.jolie-lang.org/downloads.html
currently https://github.com/jolie/jolie/releases/download/v1.11.0/jolie-1.11.0.jar
Run the installer
java -jar jolie-1.11.0.jar
Linux/macOS/WSL Homebrew
brew install jolie
Docker
docker pull jolielang/jolie
docker run -it -v /host:/container –name CONTAINERNAME jolielang/jolie
edit files in your /host, which will appear in /container
Or build from source
git clone https://github.com/jolie/jolie.git
cd jolie
mvn install
binaries will be in dist folder
Then (optionally) set up Jolie for the local user
scripts/dev-setup.sh ~/bin
Run Jolie: jolie --version
currently returns Jolie 1.11.2 (C) 2006-2022 the Jolie developers

Contract-driven development, defined by formal APIs
Structural typing instead of nominative typing
Components are services
Decouple access points from business logic
Abstract data manipulation
defined by formal APIs
service APIs should be defined in a formal language
technology agnostic
unambiguous
machine readable
based on well-known abstractions.
ironically, WSDL wasn't wrong--just bad
instead of nominative typing
since, really, the contents (structure) are what's transferred
... and any nominative information is lost
service are independently executable software artifacts
services should be clearly identifiable in source code
scope of their definition should be clearly demarcated and delimited
any given logic can/should be accessed via multiple media
therefore coupling logic to access is an antipattern
implementation of business logic should be abstract from how data is represented on the wire
services as a first-class concept
JVM underpining makes for easy integration
built-in data types beyond typical primitives
structural typing makes more sense for services
