  • "Reactive DDD, Transforming Digital Business" by Vaughn Vernon

    We’re proud to host: https://www.meetup.com/Reactive-DDD/events/259289760/ (join the waitlist, we will provide more spots soon) --- In cooperation with https://www.idddworkshop.com/ (@IDDDWorkshop) Book the Berlin IDDD Workshop April 3rd–5th, 2019 (https://t.co/1P5sjqfFa8) & In cooperation with https://www.meetup.com/Domain-Driven-Design-Berlin/ --- ✨Talk ✨ Developers around the world are moving to rapidly adopt Domain-Driven Design (DDD), and in greater numbers than ever before. That's because DDD delivers powerful results in practice. At the same time, Reactive software development is becoming essential to implementing responsive, resilient, elastic, and message-driven solutions, including event streams of fast data. This world of distribution, concurrency, latency, and the uncertainty of time-critical results, must be tackled along with the complex business challenges. This talk gives practical guidance on using DDD to model business-driven solutions that result in software that is fluent, type-safe, and with core Reactive properties. Specific attention is given to moving legacy systems that have deep debt to ones that have clear boundaries, deliver explicit and fluent business models, and exploit modern hardware and software architectures. ✨Speaker ✨ Vaughn Vernon is the founder and chief architect of the vlingo/platform for Java and .NET, a leading expert in Domain-Driven Design, and a champion of simplicity and reactive software.

  • Lieferando HashiStack Series #1

    Lieferando.de

    We love HashiCorp tools at Lieferando.de! We have various teams using one or more of Consul, Vault, Terraform, Nomad, Packer and Vagrant. Join us every month for our HashiStack series where we'll have Lieferando engineers as well as external speakers present their experiences and solutions using various HashiCorp tools. As we are Lieferando.de, you can expect some delicious Pizzas and fine beers. Agenda • 17:30 Meet & Greet • 18:30 Takeaway.com and the HashiStack • 19:00 Q&A • 19:15 Terraform project best practices • 19:45 Q&A • 20:00 Scheduling Heterogeneous Workloads using Nomad • 20:45 Q&A • 21:00 Closing statement • 21:10 - 23:00 Socializing, geeking out and more beers! • ---------------------------------------------------------------------------------- Takeaway.com and the HashiStack by Charles Akalugwu As this is the inaugural Hashistack meetup hosted by Takeaway.com/Lieferando.de it is only appropriate to begin the series with an introduction to the company and how various HashiCorp tools are currently being used in various parts of our software stack. Terraform project best practices by David Mariassy Terraform is a great new tool for managing infrastructure as code. We currently use it to provision our environments on AWS and love the fact that this tool will allow us to expand to hybrid deployments in the future whenever the need arises. There are however no standards or globally accepted best practices for Terraform project layout and deployment. This talk will outline some of our experiences as we embarked upon our journey with terraform as well as some patterns we have stuck with which works for us. Scheduling Heterogeneous Workloads using Nomad by Altay Aliyev and Charles Akalugwu In the container scheduling and management space, Kubernetes and Mesos are all everyone talks about these days. While Kubernetes and mesos are really good options, their setup could be a bit complex for most use cases. If you already use consul in your environment then Nomad is a very good workload scheduling tool as it provides seamless integration and bootstrap using consul, has no external dependencies for its operation (e.g. no separate zookeeper to manage as is the case with mesos) and really just works! We'll give an introduction to Nomad and go into the various building blocks for Nomad services including Jobs, Task Groups and Tasks. We'll also talk about the various workload drivers suppported by Nomad as well as various deployment patterns supported by Nomad (blue-green and canaries). About the speakers Charles is a founding member and Senior Software Engineer (Big Data) on the Data Infrastructure team at Takeaway.com where he works on the design, architecture and development of various cloud-based solutions for their data analytics platform. He is also responsible for organizing the "Lieferando Tech Events" group on meetup.com.

  • PyLadies: Machine learning for the curious but scared

    Lieferando.de will host the next edition of the PyLadies meetup on January 10, 2017. Abstract Machine learning is a hot topic right now, that many people get excited about. It is also notoriously confusing to get into, unless you got started on this in uni already. Despite a background in computer science, it took me many false starts to get even a bit of a hold of this topic. In my talk I want to summarize the very basic ideas that often get left out of other „Introductions“ to the topic that I wish someone had told me a few years ago. I will cover what it actually means when a machine „learns“, a high level overview of „how“ machines learn, and some pointers to friendly resources that can get you started. Afterwards, we will do a tutorial in Python introducing you to Pandas (http://pandas.pydata.org/), Scikit-learn (http://scikit-learn.org/) and Tensorflow (https://www.tensorflow.org/) to investigate a classic small machine learning problem. Speaker Ellen König (https://twitter.com/ellen_koenig) works as a Senior Data Scientist at SoundCloud (http://soundcloud.de/). She has an academic background in Computer Science, and a largely self-taught background in statistics and ML. She also loves to learn to dance and all sorts of other organized and self-taught learning on a wide range of topics. The event is suitable for beginners. Bring your own laptop with Python, Pandas, Scikit-learn and Tensorflow installed. If you did not manage to install them, come to the event 10 minutes earlier to help you set it up :) Non women attendees are welcome, but might be asked to bring a female attendee with them if there will be many non female joining. Please keep your RSVP up to date!

  • Big Data Beers Meetup: Multi-model DBs, Data Challenge and Anomaly Detection

    Lieferando Tech Events will host the forthcoming Big Data Beers meeting on 28th September 2016 in our lovely office at Am Karlsbad[masked] Berlin. There are 3 wonderful and different talks planned: 1. Next Generation NoSQL: Multi Model Databases (Michael Hackstein) 2. SMS Digital Data Challenge (Wagner, Weimer-Hablitzel, Arnold) 3. What the heck is normal? (Christian Glatschke) TALK 1: Next Generation NoSQL: Multi Model Databases The recent progress in the database development has lead us a long and winding road: 1. Using relational for everything 2. NoSQL and polyglot persistence: Introducing a ton of different technologies to learn 3. Next wave: Multi Model databases and polyglot data In this talk we will see the pros and cons of each of these stations. We will also have a more in-depth introduction to Multi Model Databases and why they are a wonderful next step in database evolution. Finally we will talk about big data requirements and how they fit into this landscape of database technologies. How can we scale and run databases in production? We are using a whole cluster of machines, collecting and mining terabytes of data with ease with the help of Mesos and DC/OS. Speaker: Michael Hackstein holds a master degree in computer science and is the creator of the ArangoDB graph capabilities. During his academic career he focused on complex algorithms and especially graph databases. Michael is an internationally experienced speaker who loves salad, cake and clean code. TALK 2: SMS digital’s Data Challenge Data Science meets Steel Industry - an exciting match of heavy metal and high tech. SMS digital presents its first open data challenge. SMS digital is the digital laboratory of the SMS group, a worldwide leading steel plant manufacturer from Dusseldorf. Its mission is to test and develop digital business models with the help of state of the art technologies. Naturally, applied data science plays a major role in this initiative. Casting slabs of quality steel is a demanding process that is highly sensitive to changes in its production and environmental parameters. Hence predicting casting defects is essential to provide ongoing quality assurance and indication for adjustments of the production parameters. The potential for optimization and the implied business opportunity are huge. So far, the primary method for prediction and detection of slab surface defects have been stochastic procedures on continuous measurements. In the future however, SMS digital hopes to improve the predictive quality of the existing procedures by applying state-of-the-art data mining and analytics methods. This will be the objective of SMS digital’s data challenge that promises a 5-figures price money for the top contributors. At our meetup, SMS digital’s team will present this data science use case, explain the provided data sets, and answer all remaining question regarding the data challenge. Speaker: Maximilian Wagner, SMS digital, CEO Max combines extensive hands-on experience in the steel industry with an ever-curious, entrepreneurial mindset. As CEO of SMS digital he’s always looking for trends and technologies that might lead to the ‘next big thing’ in his industry and beyond. Marc Weimer-Hablitzel, etventure, Senior Manager Marc combines technical knowledge, creativity and business expertise. Having worked as a Data Mining Expert for several companies in the past, Marc knows the realities and raptures of data science. Now he is on a mission to revolutionize the steel industry and the B2B sector with etventure and SMS Digital. Friedrich Arnold etventure, Project Manager As mechanical engineer and serial entrepreneur, Friedrich is very excited about the endless opportunities of the B2B, industrial sector. He’s currently responsible for testing and scaling SMS digital’s new Data Lab. Talk 3: What the heck is normal? To analyse and understand data and certain circumstances and their organizing factors, we do need a constant supervision of certain influences. In physics or information technology this could be boundary values and the definition of a 'normal' range. But who defines what is normal? Not only in psychoanalysis, also in other sciences, it is a tough challenge to tell what kind of behavior is beyond the norm. We can answer these questions today for many applications using algorithms and machine learning. This talk will show insights, principles and tools for a succsessful anomaly detection & analytics. Speaker: Christian Glatschke 17 years IT experience, 8 years Big Data and Analytic (Splunk, Lucidworks und Anodot)
