Bottom line: American’s lie almost as much as Trump. So getting valuable feedback from Americans on your products or services is a bit like digging for gold: you need to know exactly how to sift through the dirty lies to find valuable nuggets of truth. In this talk, I’ll walk you through the ins and outs on how to engage with and read Americans--or really any person--and find those valuable nugget...

WalkMe is a javascript module that integrates into web applications. Our module's performance (CPU and memory usage) is very important to us as it affects the hosting application. Measuring client side performance is not easy as there is usually a lot of noise that gets into the measurement. In WalkMe, we have built a system that can accurately measure our important performance metrics and visuali...

Functional Programming paradigms are great in many aspects, but can they lend themselves to the actual design of the service? If so, can they also lend themselves to the entire system architecture? This talk will show how we, at AppsFlyer, utilize ideas such as immutability, function composition, CSP, CQRS, referential transparency etc., in order to design our system - from the inner-service level...

As programmers, we encounter stress in many forms: release dates, production bugs, hack even some code reviews can become stressful. I’m pretty sure that everyone got his share of stress while working in the industry and experienced some of its negative effects on his physical and emotional wellbeing. The thing about stress is that it slowly creeps in and sometimes we are not even aware of it’s ex...

The story of Re:dash, that in the past 3 years grew from a hackathon project, to a side project to a business. I will share the story, what is Re:dash, how to transform and open source project into a business and lessons learned from this experience. MP3

I have been a developer for about a decade. Despite always wanting to contribute to open source, it took me a very long time to finally get around to it, and I encountered various difficulties along the way. This presentation will describe them and provide advice to make those first baby steps easier. MP3

Search engine technologies (Lucene, Solr, Elasticsearch) have poor support for Hebrew out of the box. מה לעשות, עברית קשה שפה. The only way around this was to create a custom Lucene analyzer that is smart enough to disambiguate Hebrew words and manipulate the index accordingly. Today HebMorph is being used by many users, some under an OSS license and some under a commercial license to support the...

August Penguin is the annual gathering of the Israeli Free and Open Source Software community. It has been occurring for most of the past 15 years, and is organized by volunteers in the Hamakor NGO. After several years in attendance and after taking part in similar conferences abroad, this year I decided to take an active part in organizing the event. This talk will go over the story of how we org...

“The Dunning-Kruger effect is a cognitive bias in which relatively unskilled persons suffer illusory superiority, mistakenly assessing their ability to be much higher than it really is” It is known that developers don't necessarily make good managers, yet most companies (us included!) make the mistake of "promoting" successful developers into managerial positions. That is flat out wrong. A develop...

When you have a web app owned by several teams - very soon you will need to handle issues like: quality, ownership and autonomy. Using the “micro services architecture” hammer is not that trivia when your nail is a monolithic web application. How do you handle: session management, security, cross apps links and user experience ? In this talk i will describe how we did manage to solve most of the i...

Cloud computing provides amazing capabilities for the modern application, but there are many pitfalls to be aware of – scalability, resilience, elasticity, security and more. In this session we will look at basic must-know patterns when architecting for the Azure cloud: Message-Oriented, Poison Messages, CDN, Priority Queues, Retry Patterns and more. MP3

Building a decent app is easy this days, there are plenty of tutorials, videos and blog post about it. In this session I'll try to go over some of the top mistakes that everyone of us is doing while building his app. This will cover all the aspects of building bad app- technical, UI & UX, and marketing. So each one of you will be able to adapt his own favorite bad pattern and ruin his app. MP3

Chat bots are the latest AI trend, featuring bots that do anything from ordering flowers to being your lawyer. In this session I will present a content chatbot and how it is built. The synergy between NLP, search and Outbrain's recommendation algorithms enables us to understand the user’s information need from the chat, and respond with relevant and timely content. These play together in building...

At AppsFlyer we provide a real-time analytics dashboard for Marketers. With our dashboard they invest $$$ budgets wisely. We aggregate some 8 billion daily events in real-time and our solution could not handle this load - dashboard just loaded forever and the Kafka lags were our daily and nightly headache. Product constantly demanded new features and guess what - we just couldn't do it! Moreover,...

It all starts with working together. The term "DevOps" holds much more than just a new job description for operation people. For us, it is a way of life. We create our own flavour of DevOps organization, including system ownership, combined teams, tools and much more. This will be our chance to share our good experience about how it can actually be done and why it might be good for you, your DevOp...

DevOps, #NoOps , #serverless - every few years yet another movement to get rid of those pesky Ops engineers no one likes pops up. But like cockroaches, we can’t seem to be able to get rid of the buggers. Can it be we just don’t really understand what “operations” is all about? When people hear “Operations”, they think of managing servers, of automation, CI and deployment pipelines. But Operations...

I've spent most of life amongst storytellers in journalism, stage and screen. I've spent the last two hiring and working with great engineers at Wisdo.com. It's my profound belief that great code writers are artists in soul and practice and that the architecture of stories can and should be taught to those who spend more of their days - solving stories rather than writing them. Code needs to serve...

This is not yet another technology list, buzzword packed, look-how-good-we-are show off. Actually it is technology/language agnostic and I promise not to say Docker even once ;) The newcomer into this world is overwhelmed with information, patterns, tools and practices. Having delivered numerous such projects, I'll try to separate the wheat from the chaff. This is a clear recipe for the key practi...

At Ravello Systems we were relying heavily on CI/CD since the very early days. During the first 4 years of the company, our CI/CD framework changed and evolved to the point it went out of control and we decided to take all the experience from these years into a new and improved CI/CD. This session will share the lessons that we learned when we used multiple different tools as part of our DevOps wo...

The full story behind a highly successful immune system we implemented for the "New Google Sites". We will discuss key decisions and present the design of the system that we built, touching a wide range of devops topics: Production tests Webdriver vs. RPC probers What environments we have and how are they pushed (CI/CD, etc.) Capacity testing, load testing, Canarying What worked, what went wrong,...

Learn how easy it is to learn and use Elixir and Cowboy (A concurrent and fault-tolerant HTTP server) in a short time - from figuring out how to build a distributed In-App messaging system, to deployment and production. You'll also hear about why Erlang/Elixir are perfect for realtime messaging. MP3

Mal (Make-a-Lisp) is a Clojure-like Lisp language invented by Joel Martin for educational purposes. It has interpreter implementations in 56 programming languages, including C, Java and Python, but also Make, PL/SQL, Vimscript and many others. Building a Mal implementation is a great way to learn about Lisp in general and about the specific language you're implementing in. The talk will present th...

Considering “Conway's Law” as an axiom, I aim to consider several aspects of how the organizational communication structure effects software design. Rapid changes within cross-timezones organizations influence software architecture processes. What can engineers or architects do to guarantee a productive and quality assuring design and implementation process, that foresees ongoing organizational ch...

We are all constantly told that having a healthy work-life balance is critical, but what does it really mean? Can we really separate life and work? Forget everything you ever heard about work life balance, and find out what you can do instead. MP3
