Hi!

Come and learn from C# practitioners how are they using advanced .NET concepts and patterns in real life. If you wondered if Rx is a thing, or how code generation works in .NET this is the right place to be.

You are welcome on Martch 14 at 18:30, Zaļā iela 1, 4th floor (Microsoft Latvia office).

Agenda for .NET focused 73rd DevClub.lv:

• Ivars Āriņš from Adaptive Financial Consulting will give a talk “Introduction to Reactive Extensions”.
  Reactive Extensions for .NET (Rx) help developers to deal with sequences of events and there are lot of problems that can be modeled in such a way. The talk will cover basic aspects of Reactive Extensions, such as Observables and Observers, combining and transforming sequences of events. We will briefly look at how Rx compares (and interacts) with async programming and what are the caveats there.

• Arthur Tabatchnic will give a talk “Building .NET Core tools using the Roslyn API “.
  The Roslyn C# gives developers access to the C# language parsing and generation capabilities. This can be leveraged in many ways by building tools that fully understand the code and are capable of generating new code with full comprehension of your codebase. In this talk I will walk you through the basic concepts of the Roslyn and language parsing, building a small tool using these principles and packaging it as a .NET Core tool for easy distribution and usage via the .NET Core CLI.

  What is a distributed system and how to glue the applications in it? Messaging is one of the powerful ways to do that. Let’s go through the common messaging communication patterns together. Recall some theory, understand the difference between message brokers and message buses and see how the last ones help us focusing on writing business features and not concentrating on low-level communication details. The talk will be illustrated with a lot of real-life examples from the Insurance industry.

You are welcome on February 20 at 18:30, Zaļā iela 1, 4th floor (Microsoft Latvia office).

Agenda for FrontEnd focused 72nd DevClub.lv:

• Alfreds Genkins and Ilja Lapkovskis from Scandiweb will give a talk “Modern PWA experience with old generation e-comm platform – the reasons, techs and goals”.
  In the last time PWA became another hype word in web development. There are tons of promises, multiple selling-point features, but after all – these are we, technicians, who empowers all these. Right now Scandiweb is about to release first real-life Magento 2 PWA application, which has reworked UI to utilizes power of PWA and why we adopted it into the old stack. During our speech we want to destruct all the hype and marketing to share the tech behind these, new opportunities and ofcourse new challenges:
  – What is PWA and can it be simple with all these cool features and marketing promises
  – How to implement PWA for complex scenarios and highly dynamic applications, i.e. e-commerce platform
  – Real life example – how Scandiweb recreated Magento frontend to make it feel native with React JS and GraphQl
  – Technology and tool market – how it looks in the beginning of 2019.

• Dzulqarnain Nasir from Geta Digital will give a talk “Dependency Injection in JavaScript with InversifyJS”.
  Dependency injection is a programming technique that makes a class independent of its dependencies. It achieves that by decoupling the usage of an object from its creation. This helps you to follow SOLID’s dependency inversion and single responsibility principles. In this presentation, I will demonstrate how this can be achieved in JavaScript using an IoC container library called InversifyJS.
  (Language – English)

Hi!

We wish you Happy New Year!
Lets start it with Java focused DevClub.lv.
You are welcome on January 24 at 18:30, Zaļā iela 1, 4th floor (Microsoft Latvia office).

Agenda for Java focused 71st DevClub.lv:

• • • Pijus Navickas from WIX will give a talk “First date with GraalVM”.
      Milda Glebauskaitė from WIX will give a talk “Breaking language barriers with GraalVMs polyglotism”.
      GraalVM – the newest JVM extension generated a lot of buzz in the industry,  already earning the trust of such industry giants as Twitter. The promises GraalVM gives definitely sound good: a better performance, as well as seamless interoperability between multiple languages, all running on the JVM. Should we be interested in it too? In this talk Pijus will explain, what exactly is GraalVM and what hides behind the scene and Milda will demonstrate GraalVM polyglotism, exploring weather we can actually create seamless applications, selecting the best programming language for our tasks, without the overhead.
      (Language – English)

    • Arturs Drozdovs from Intrum Global Technologies will give a talk “The one and only way of designing Java applications”.
      There is no “one and only” way; each team has to choose the most suitable approach for their situation and project. What is common throughout all the teams is the need to make choices. In this talk we will look at the choices we’ve faced in our team, what options did we consider and what conclusions did we come to.
      (Language – English)
      Tags: fintech, java, boilerplate, architecture, frameworks, exceptions, packages

      Arturs is a software developer at Intrum Global Technologies. He has extensive experience splitting monolith projects into microservices, as such tightly interacting with architectural decisions on all levels of abstractions.

    • Olegs Anastasyevs from ok.ru will give a talk “Resilience in Distributed Systems”.
      ok.ru is the most popular social network in Russia and top 20 website in the world. And it is one of the largest, complex and highly loaded distributed system: 1000s of servers participate in user requests processing in real time. Each of these servers has only small part of data locally and implements only a fraction of processing logic. Social network can hardly be built using shared nothing architecture, so there is a lot of shared state, network communications happens between our servers, different in kind and widely varying in volume.
      In distributed system of such scale we can hardly find a single second free of some failure, glitch or lag. How to build a continuously failing system, which works correct nevertheless? What are full and partial failures and how to address them?
      What do idempotence and speculation mean? What should be implemented upfront to workaround outage of the large subsystem or “main” database? How to manage pre-production tests and release delivery?
      There are many hard questions in distributed systems development. In this talk I’m trying to give ok.ru answers on them.
      (Language – Russian)
      Tags: resiliency, distributed, microservice architecture, highload

You are welcome on 6th December at 18:30, Zaļā iela 1, 4th floor (Microsoft Latvia office).

Agenda for FinTech focused 70th DevClub.lv:

• • Erik Kaju from TransferWise will give a talk “How to build a payment card product”.
    For a long time payment cards used to be the domain of banks. In the last decade, the paradigm has shifted – we see more and more regular enterprises issuing their own cards, be it telcos, grocery store chains, various fintech startups etc.
    But what does it take to build a payment card from scratch? How do cards work? What is the anatomy of card transactions?
    This is a talk focusing on technical and product aspects of the card issuance, based on true story.
    (Language – English)
    Tags: Payment cards industry, issuance, transaction lifecycle, microservices

    Erik is leading the payment card product engineering at TransferWise. Loves all aspects of product engineering – from validating the market fit, establishing partnerships and negotiating deals, to designing technical architecture, building the team and bringing hyper-growth products to live.

  • Dmitry Buzdin from a-heads consulting will give a talk “How payment cards really work”.
    This talk is an introduction about technical aspects of how payment cards function, what technical protocols are involved and what are implementation complexities in a typical payments project. You will learn about concepts like 3DSecure, Authorisation and Clearing, Tokenization and know about novelties in the payment world, which will affect consumers in the nearest future.

• • Jake Sebastian-Jones from Nordigen will give a talk “Data is not enough, you need information”.
    Having a lot of raw data by itself is meaningless – you need to extract information from the data. Banks and other financial institutions have a lot of data but surprisingly little information. This talk will explain how Nordigen uses transaction data to provide multiple tiers of information to financial service providers.
