• The Elephant in the Room: Our Relation to Databases and their Secrets

    It's Meetup time once again! ๐ŸŽ‰ Join us on August 22nd for an amazing evening, all about databases. ๐Ÿ˜ As always, ๐Ÿบ and ๐Ÿ• are on us! ๐Ÿ“‘ Program: - 18:00: Doors open ๐Ÿšช - 19:00: Talk by Sjoerd Cranen (Picnic): The Elephant in the Room: Our Relation to Databases - 19:45: Talk by Lukas Eder (Data Geekery GmbH): How Modern SQL Databases Come up with Algorithms that You Would Have Never Dreamed Of - 20:30: Networking ๐Ÿ™‹๐Ÿผโ€โ™‚๏ธ๐Ÿ™‹๐Ÿผโ€โ™€๏ธ --- ๐ŸŽค Speakers: ๐Ÿ”ธ Sjoerd Cranen Sjoerd Cranen is software architect at Picnic. After starting a job in technical automation, and then leaving that job for a Ph.D. in Computer Science, he is now helping you with your groceries, and that for the last 3.5 years. You can wake him up at night for a beautifully crafted piece of code, an elegantly simple software design or a beautiful relational data model. ๐Ÿ“ Abstract: Weโ€™ll talk about which database technologies are in use at Picnic, what we use them for, and what we learned while using them. After that, we will briefly look at how software engineering and data engineering come together at Picnic, and what that means for our data infrastructure. ๐Ÿ”ธ Lukas Eder Lukas Eder is founder and CEO of Data Geekery GmbH, the company behind jOOQ, located in St. Gallen, Switzerland. He is fascinated by the interaction of Java and SQL. Most of this experience he has obtained in the Swiss E-Banking field through various variants (JDBC, jOOQ, Hibernate, mostly with Oracle and PostgreSQL). As a Java Champion and Oracle ACE, he is happy to share this knowledge at various conferences, JUGs, in-house presentations and on his blog. ๐Ÿ“ Abstract: SQL is the only ever successful, mainstream, and general-purpose 4GL (Fourth Generation Programming Language) and it is awesome! With modern cost-based optimization, relational databases like Oracle, SQL Server, PostgreSQL finally keep up to the promise of a powerful declarative programming model by adapting to ever-changing productive data without performance penalties. Thousand-line-long, complex SQL statements can be run in far below a millisecond against billion-row strong tables if database developers know their ways around the SQL language - and the best news is: Itโ€™s not that hard! In this talk, Iโ€™ll show how the SQL database will constantly outperform any handwritten data retrieval algorithm - or in other words - how SQL, being a logic language, is the best language for business logic. --- ๐Ÿ“ Location: Picnic Technologies Van Marwijk Kooystraat[masked] AG Amsterdam

  • Machine Learning & Logistics: An evening @ Picnic

    Van Marwijk Kooystraat 15

    It's time for yet another Meetup! ๐ŸŽ‰ Join us on July 18th for a great evening about Machine Learning and Software Engineering. ๐Ÿ˜ As always, ๐Ÿบ and ๐Ÿ• are on us! ๐Ÿ“ Program: - 18:00: Doors open ๐Ÿšช - 19:00: Talk by Bas Vlaming (Picnic): Machine Learning in Logistics: Optimising distribution one delivery at a time - 19:45: Talk by Thiago de Faria (LINKIT): ML Lifecycle, Continuous Evaluation & DevOps - scaling your ML efforts - 20:30: Networking ๐ŸŽค Speakers: - Bas Vlaming Bas Vlaming is a data scientist at Picnic. He holds a Ph.D. in physics and worked at MIT and Ocado before joining the team at Picnic Technologies two years ago. He has a keen interest in obtaining data-driven insights into and thereby optimizing processes in complex environments, leveraging a wide variety of computational techniques. In this talk, he will explain how neural networks can be used to better predict how much time should be allotted to grocery deliveries, and how this leads to a much more efficient distribution model. We will go through the full development cycle: from gathering relevant data and dealing with unreliable inputs, via feature selection, model development and optimization, to building a robust and scalable framework so that the model predictions can be used in Picnic's operation. - Thiago de Faria Thiago de Faria is the Head of Solutions Engineering at LINKIT, a knowledge-driven organization with IT experts supporting partners with a transparent path toward pain mitigation and solving business problems. Your ML/AI Engineers build great models, but do you feel that after the model is "ready" still take time to reach Production? Do you think you could move faster? That's where a DevOps mindset comes in: reduce the batch size, continuous-everything, a culture of failure/experimentation, monitoring & sharing. These principles can be translated into your data team & improve your ML lifecycle.โ€ "You are here because your team is building ML modelsโ€ฆ but when do we use ML? To solve problems that machines can find patterns without explicitly programming them to do so. And you may have great ML/AI Engineers building great models, but do you feel that after the model is โ€œreadyโ€ still take too much time to reach Production? Do you think you could move faster? Help them use more Testing principles? Maybe share what they have done? It is important to know that CI/CD is essential, but we need to talk about CE โ€“ Continuous Evaluation -, reduce waste of time and resources while reworking models. In the end, I will show how the workflow of ana ML Engineer/Data Scientist can be in real life with a live demo! ๐Ÿ“ Location: Picnic Technologies Van Marwijk Kooystraat[masked] AG Amsterdam

  • Angi + Picnic โšก๏ธ How Lean Experiments help you build products customers want

    โœจ In this special edition, we'll partner up with Angi for a brand new Meetup all about innovation and Lean experiments! With the development of new products it's no longer about a 'good' or 'beautiful' product, it's about the right product. 80% of all new product ideas fail because customers simply do not care about it. Lean experiments can help you learn from your customers, continuously. By doing this, you'll stay relevant to your customers and see your business grow. "The only way to win is to learn faster than anyone else." โ€” The Lean Startup During this Meetup, Angi Studio will give you an introduction to those Lean Experiments. We'll talk about how small experiments help you turn your assumptions into facts and why running more experiments will lead to more success. Wiemer Viet, our very own UX Designer, will share a really cool case on how his team created the new Runner app by doing more than 60 user-tests and 11 design iterations.

Demystifying serverless deployments with Zeit Now" by Chris Kipp 20:10 - Networking ๐Ÿ‘จโ€๐Ÿ’ป Secrets to Speeding up React SSR with ESX by David Clements (https://twitter.com/davidmarkclem) As a Principal Architect and Consultant at NearForm, it has become painfully clear that React's Server-Side Rendering (SSR) is a performance bottleneck for web backends around the world. That's why I made ESX, it's a simple solution that can be dropped into pre-existing React applications to significantly improve Server-Side rendering throughput. This talk not only demonstrates ESX but also explains how it works with live coding examples. About David Principal architect at NearForm and the author of โ€œNode Cookbookโ€ (https://www.packtpub.com/web-development/node-cookbook-third-edition). ๐Ÿ‘จโ€๐Ÿ’ป Function-As-a-Service? Demystifying serverless deployments with Zeit Now by Chris Kipp (https://wiki.chronica.xyz) Don't let confusing terms like "serverless architecture" and "function-as-a-service" confuse you. Let's take a step back, define what these words mean, and dive into what a serverless deployment looks like. We'll use Zeit's Now platform as a super simple example of how easy it is to get serverless applications up and running.
