Scala vs. Perl vs. Dart

Nearly our entire server codebase is written in Scala (if you haven't heard of it, it's a programming language that is basically what you would get if Java + ML had a baby). This has worked out super well. It enables us to write concise easy to deal with code that is typechecked at compile time. It's also been a big help with recruiting.

Programming language

We use Scala instead of Java to build Android App faster and more gracefully.

It's the language of Spark. DStreams and transformations.

Fo it's functional prowess

Used to build a wrap over Gatling to automate the stress testing.

I've been using scala commercially since 2008 in Banks and other projects.

Functional and conccurency programming

Replaces entirely the Java Language to build a much more expressive and powerful code on the backend, while leveraging at the same time the Java Platform Tools and Frameworks, is a mixture of old and mature with new and sexy.

Writing Scala is an enjoyable experience. What's more satisfying then using map to process your data in an array.

Scala, Akka and Spray (which became Akka-Http) provided the building blocks for the menu service.
Akka's actors and finite-state machine were a natural way to model a USSD menu (a series of stateful interactions between a subscriber and the USSD gateway).

Scala is the God of languages. A legend. The Mount Rushmore of hybrid OO/functional languages is Scala's face four times over.

Ok, honestly, we love Scala. We love(d) Java (and it's parents C and C++), and we love(d) all the languages that borrowed cough stole cough from Java over the years such as Groovy, Clojure, and C#.

It may not be perfect (it totally is, but since programming languages don't have egos of their own, we don't want to paint it too bright), but it is awesome. It runs on the JVM, you can utilize Spring, it works great for data processing (which is sorta kinda the thing we do here, folks), and it just makes sense at all levels.

If you don't like Scala, we feel sorry for the projects that are suffering due to your choices, meanwhile we are using Scala to write everything from JavaScript, CSS, SQL, and JSON directly within itself (go figure), so in the end no one will know the beauty of this powerhouse language (except for our engineers, of course).

New micro services are on this stack

Programming language for the core SRX tools

Functionnal Programming at its best.

worked with scala for around 2 years. really enjoyed the language and getting back into the world of functional. unfortunately the community is heavily fragmented and the language itself broken and inconsistent. that with the various factions involved made it a put of for long term investment.

We use perl with rex to control our distributed systems.

I use perl on some legacy applications.

I use Perl to rip through log files and compare them to some signature files I have created. When I get a match, it adds the bad guy to the list of shame in MySQL.

The whole backend part (deployment and other scripts, business logic, web interface) is written in Perl.

Весь бэкенд (скрипты деплоя и прочие, бизнес-логика, веб-интерфейс) написан на Perl.

Some legacy code is written in Perl

A very expressive language, lets you say the same thing in many different ways

I will use Dart later to handle the payloads from Roblox and all API requests.
