Cloud computing

The latest edition of "The Programmer's Guide to the Universe" (our standard repository for all knowledge and wisdom) lists three definitions for the term “Code Forward”:

1. In finance, a forward contract (also known as a forward) is a type of a derivative instrument. It is a customized contract between two parties, whereby one of the parties agrees to buy a specific asset at a specific date in the future at a predetermined price that is agreed upon today. A code forward is a contract where the underlying asset is software and the seller is a developer, a group of developers, or a specialized broker.

2. Code forward (Latin: programma deinceps) is an aphorism derived from the poetry of Horace (Latin: Sextusdecimus Horatius Abacus), which can be found in his “Odes To Algorithms” (2, 48, 4). The ode praises a young software developer learning new technologies, and the phrase "Code forward!" is a motto repeated throughout the poem by the lyrical subject as a means of encouraging the developer not to stray from his path.

3. Code Forward is a conference for software developers organized by software developers, which will take place on April 7, 2017 at the Sound Garden Hotel in Warsaw. It is a meeting of enthusiasts who decided to dedicate their professional careers to writing, testing, and maintaining code. It’s sponsored by Credit Suisse and Luxoft and is entirely organized by a group of passionate programmers working for these companies. The range of topics covered by the speakers is wide, but since conference time is limited, participants should expect a natural bias towards areas that the creators of Code Forward find especially exciting, such as Cloud, DevOps, and Big Data.

DevTest Pairing in DevOps

We want to show you how efficient DevTest pairing can be in your projects! It doesn’t matter whether you work in Agile or waterfall, or whether you have your teammates sitting next to you or work in a distributed team. You can do it everywhere and always – it’s a matter of good will. Based on the DevOps setup in our organization and our Agile ceremonies, we want to show you the benefits we get from such pairings to survive in that DevOps environment, including how we manage parallel requirements from different directions combined with PCI compliance and complicated release processes requiring multiple divisions cooperating. DevTest pairings give us a way to move tasks more smoothly and efficiently, building a common goal for all team members. We will encourage you to try it in your teams and projects and enjoy the benefit.

Water-Powered Machine Learning – Gradient Boosting Machines in H2O AI

Machine learning is getting more and more popular. Deep Learning in particular is getting a lot of attention, mostly because of Theano, TensorFlow, and other highly optimized libraries. And while Neural Networks are fascinating and very exciting, there are other algorithms that have been proven to be fast, scalable, and very accurate in practical applications. Extreme Gradient Boosting is one of them.

As volumes of data grow, task machine learning is becoming more challenging – not only do you need to figure out which algorithm to use, but you have to crunch your data somehow. If it is a couple of megabytes in size – that’s fine. A gigabyte or two is still ok. But what if you have to analyze more? Balancing accuracy and predictive power with scalability and ease of use is not an easy task.

The idea of an actor model isn’t new – it originates in the early 1970s. The model addresses the challenges of concurrent computations and, one of the most prominent implementations of the model was done in the Erlang language designed in Ericsson laboratories by Joe Armstrong, Rober Virding, and Mike Williams over 30 years ago.

It enabled Ericsson to produce the most reliable switch device possible at that time. The qualities of the actor model have not passed unnoticed by Jonas Bonér, who, with Martin Odersky, founded Typesafe to promote reactive programming principles. Akka has become a flagship of Typesafe, quickly finding many adopters in the rapidly growing Web 2 industry. 

The Actor programming model has proven to address not only concurrency challenges, but has also been extended to run distributed systems – a.k.a. Akka Cluster. During my talk I will present the main qualities of Akka that have paved its road into the minds and hearts of developers. I will focus on resolving concurrency issues as well as the patterns that you can apply in your daily work to improve your system reliability.

Let’s Play – Quality Micro and Macro

Świat IT został opanowany przez mikro serwisy. Nowe podejście do architektury ma zapewnić szybkie oraz wygodne budowanie modularnych, niezawodnych, a przede wszystkim łatwo skalowalnych systemów. I tak jest. Mikro serwisy, zrobione dobrze, rozwiązują wiele problemów, które pojawiały się w przypadku monolitycznych systemów. No właśnie - zrobione dobrze. Zrobione źle, o co nietrudno, mogą przynieść więcej problemów niż korzyści. Nie mamy jeszcze doświadczenia z nową architekturą i cały czas uczymy się jak implementować mikro usługi. Warto jednak pamiętać, że nowe podejście architektoniczne wymaga także nowego podejścia, jeżeli chodzi o zapewnienie jakości. W swojej prezentacji chciałbym opowiedzieć o produkcie nad którym pracuję, a który realizowany jest w oparciu o mikro serwisy. Nie chcę jednak opisywać to szczegółów dotyczących kodu, czy użytych narzędzi, ale przede wszystkim w jaki sposób staramy się zapewnić jakość przy zupełnie nowym podejściu do architektury. Zarówno na poziomie mikro - czyli pojedynczych serwisów, jak i makro - na poziomie całego produktu, opartego o ponad setkę pojedynczych aplikacji.

Lean Principles in Testing 

Evolution instead of revolution means LEAN principles in Software Testing. IT companies are divided into 2 sides of the conflict, with each of them supporting different methodologies – Waterfall and Agile. Agile methodologies are trendy and sexy and made IT managers start a revolution, but often without any reflection on the Agile Manifesto and how it fits into their company strategy. Then, things like “Agile in a bubble” began to appear – when the rest of company uses Waterfall, we have our Agile team.

No one gives us feedback, we cannot cooperate with other teams, but we are AGILE. Too often, managers use brute force Agile implementation, when they should consider alternative approaches. How to improve processes? How to eliminate waste? How to implement LEAN principles in testing? It’s hard to implement a good Agile approach when the team is not ready or when the mindset is wrong. But if our waterfall process works, why should we? Shouldn’t we focus on process tuning and making it even better? Waterfall can also have iterations, so we can start testing from the very beginning and improve what we have.

Chaos report (2015) states that for large projects, only 3% of Waterfall projects were completed successfully vs. 18% in Agile. Managers see these numbers and start to implement Agile in their companies. When you start asking questions about values, about how they handle audits and regulators, how they share information across teams, it occurs that these people work in Waterfall. Is that bad? No – they deliver projects on time and to budget, they eliminate waste, and they share good practices with other teams – kudos to those managers.

The discussion panel (preferred) or presentation aims to introduce the LEAN and Kaizen philosophies in testing and encourage participants to analyse the process of testing they are working with and implement improvements that will help them in their daily work – evolution rather than revolution, in other words. If our process successfully delivers software to the customer, instead of turning the whole company upside down, we need to consider a series of amendments aimed at improving our daily work.
