Part 2… I find that I repeat myself often at work.
Ms Peggy Theodorou-Zoumi on behalf of Advantage FSE, welcomed the members of JHUG at their premises for yet another more time as they are fond supporters of our group and they too believe that people are the most important value in our industry.
After this warm welcome the organizers Thomas and Spyros took the word to motivate members to give talks for the forthcoming events. Since both of them are experienced engineers there was a clear separation of concerns in their calls and one asked for subjects while the other for speakers.
Do some research, experiment a bit and come to give a talk.
I am sure it will be very good. Spyros Our community is growing and there are many new faces in each meetup. The best way to get to know each other is a lightning talk. Come up and tell us who you are, what you are working on, what you have to tell and what you want to hear.
A lightning talk for 10 minutes on any topic is very easy to do and will help to evolve and grow the community even more. There is a form to declare your interest in giving a talk and we urge you to submit a proposal.
Remember that the most important thing for a talk in communities like ours it to create traction and empathy. The value of the talk is important but secondary. And now the major part, the talks.
He is a regular member of JHUG and has given us very interesting talks on mobile computing. It was released as open source in and there was a major interest in it when Google announced it as a language for Android development in The talk was targeted to programmers familiar with Java.
Antonis presented in a concise, sweet and up to the point way the features of Kotlin that make it both attractive and productive. It is not an academic language or an experiment, it is designed for modern applications. It runs on the JVM but it is not an extension or an upgrade to Java.
Familiarity with Java helps a lot to reduce the learning curve but it is not a prerequisite. Kotlin is a statically typed language that supports both object-oriented and functional paradigms. It has first class functions, type inference, some nice syntactic shortcuts like null check operators, safe casting, companion objects and many more structures that look natural in Kotlin but compared with Java they greatly reduce boilerplate code.
Kotlin also supports composition instead of inheritance as the primary mechanism for extending classes and has data classes which in essence are value classes generated by the compiler. It has also a proposal for structure concurrency in coroutines which you can think of as very lightweight threads.
The slides are very descriptive and you can start programming in Kotlin just be reading them. It is supported by all major IDEs.
The toolchain for it is quite stable and keeps improving as the language gains interest. At the end Antonis answered questions about the stability and the future of the language. In my opinion Kotlin is another language for the JVM like scala, groovy, clojure and it has to answer the same question: It certainly makes programs easier to write but are there any safeguards to preserve the readability?
The advantage for Kotlin is that is has a very suitable environment for it as it is a first citizen language for Android and the characteristics of mobile apps favor such high level languages.
Kotlin is definitely a project to track and this talk by Antonis did a great job to promote it. Pizza, Beers and Networking This is one of the best parts of every meetup. A break during the two talks for pizza and beers kindly offered by our host Advantage FSE.
He chose to present Istio a new and trending technology which most attendees were not acquainted with. The talk was intended for newcomers and it was also a tutorial for service meshes in general.
Georgios started describing microservices architectures and how their essence, that no matter how you design them they are a distributed system and underneath them there is an unreliable network, is the cause of most problems.
He then presented and analyzed the major architectural challenges regarding distributed systems like resilience, fault tolerance, load balancing, canary deployments and discussed potential solutions.If you are interested in trying Emacs, with evil-mode of course, there is a great starter kit for writing Clojure.
Luckily there are a variety of great plugins to enhance Vim’s editing capabilities for editing Clojure, aside from switching our entire editor. How much are your skills worth? Find out how much developers like you are making with our Salary Calculator, now updated with Developer Survey data.
You are correct that you need to compile the schwenkreis.comx namespace to produce the class files before you can include it.
That kind of tight feedback loop will be useful while learning Clojure and, later, when writing real Clojure programs. Emacs is also great for working with any Lisp dialect; in fact, Emacs is written in a Lisp dialect called Emacs Lisp (elisp). By the end of this chapter, your Emacs setup will .

I keep seeing "bootstrapping" mentioned in discussions of application development. It seems both widespread and important, but I've yet to come across even a poor explanation of what bootstrapping.
This is sometimes useful if you are writing a class for consumption by a Java library and schwenkreis.com is only a test harness for developing, though it's . Since you will spend most time in your editor writing and changing code customise it to make it comfortable, if that is an existing editor then look to see if someone has already created an integration to Clojure.
However, you should try Emacs because it has an integration with Lisp-type systems, also its configuration is Lisp so should not be too hard for you to understand. 2 day conference in London, United Kingdom. Back for a seventh installment, the Haskell eXchange is an annual conference created for and by the Skills Matter.
