As developers, we are constantly focused on writing elegant and cutting edge code, however, meaningful code lives 99% of it's life in production, away from our prying eyes looking at an IDE screen. in the span of those 99%, issues are bound to arise and someone will have to deal with them (probably at 3 AM after a pagerduty call). 3 years of being on the on-call rotation for mission critical servi...

Redis is a high throughput key-value store, but in order to provide high performance the designers had to leave out a lot of user specific features. In Redis 4.0 modules were introduces to the comunity - A way for users to add custom functionalities to the fastest data store available. With Redis Labs operating mainly from Israel Tel Aviv has become the source of many great modules implementing fu...

The truth is that you can’t handle the truth. No system can. Cheating in large computer systems, just like white lies around the holidays, is inevitable. We live in a constantly changing universe too dense and volatile for a mere computer system to generate a perfect response. So we cheat, but it’s for the common good. It is crucial for any engineer to be able to separate the absolute “scientific”...

In the world of Phishing and malware attacks, hackers face many obstacles which they can only outsmart via sophisticated, often twisted methods. Furthermore, today’s large scale cyber campaigns require complex communication infrastructure with thousands of infected machines. DNS is a corner stone of the internet and as such is likely to contain unique footprints of such communication, seemingly co...

I started work at Klarna four years ago, and for the first time in my life I was surrounded by developers all day long. I found myself feeling like Captain Kirk when he first met Spock. I'll tell you a bit about working with developers from my personal perspective. I'll share the things I've learned about you, the differences between people in HR and developers, and talk about what we can do to ma...

Meritocracy: a political philosophy which holds that power should be vested in individuals almost exclusively according to merit. If you're reading the above, nodding your head, wishing it was the case in your situation maybe I can help. I'd like to offer some ideas and tips for the struggles Technical Leads or Senior Engineers are facing: How can you leverage your skills to move the organization...

Detecting anomalies in big data sets is challenging, but rewarding. When you know to distinguish anomaly from normal - you know your data. In the presentation I will cover our, somewhat novel approach of anomaly detection in big data sets and explain both mathematical and technical difficulties applying it over big data sets. Our approach is about discovering statistical properties of the data sub...

Static Analysis is a very effective tool to improve code quality. Integrate it into the code life cycle requires both your cultural and technical attention. In this talk I will show horrific examples of what we have found in our code base, and the process we did taking FindBugs from a P.O.C into a one of the main pillar of our Immune System. MP3

Ever heard of a "Quine"? A Quine is a program that reproduces itself. Basically - it takes no inout and produces its own source code as the output. Sounds tricky? Let's learn how to write one in Ruby in 5 minutes! MP3

Back to the Future, Star Trek, Terminator - Almost every sci-fi movie we grew up on presented some slick futuristic technology. But while some of these films turned out to be successful predictors of the future, others missed miserably. From hoverboards and tablets to telleporters and time travel - Which technologies were successfully predicted? Which movies shamefully failed? And what can we lear...

Coderetreat is a day-long, intensive practice event, focusing on the fundamentals of software development and design. It is also a lot of fun. We at Kenshoo are doing those periodically - hear why, and learn how you can start as well. 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...

If you take delivering a fast web experience seriously, then you have to make sure you’re utilizing HTTP’s ability to serve the response in chunks. Using “Chunked Encoding” improves performance by letting your server flush critical parts of the document (like the head tag) early, which means the browser can start downloading other resources sooner. And even though this has been part of the HTTP pr...

On December 2015, during an internal Wix Hackathon, we decided to rewrite our aging Micro-services infrastructure. This is our story. In this story, we will see how to build a modern infrastructure that enables you to deploy a self-servicing grid of computers on which micro-services can run and discover one another. Will I show the best way to build a Micro-services infrastructure? No, but I will...

Sharing tips and tricks for raising early stage funds in Israel and beyond. We'll quickly cover some basic terms, but try to focus on insights that aren't widely available online. MP3

We all agree that recurring operational tasks are time-consuming nuisances, which should be eradicated using automation. However, sometimes they require careful coordination, hardware manipulation and worst of all - human interaction. Recently, we found that our code doesn’t really need to pass a Turing test in order to successfully interact with humans, and convince them to partake in an automate...

Java prides itself in not allowing you to shoot yourself in the foot, but doesn't always live up to the hype. Recent editions have introduced powerful new syntactic tools which make development much easier, but can often result in "WAT" moments. This lightening talk, inspired by Gary Bernhardt's famous WAT talk will showcase some of the cases where Java has left me scratching my head and asking "W...

Concurrency in modern computers has changed. Moore’s Law, which observed that “the number of transistors in a dense integrated circuit will double approximately every two years”, is no longer true. Nowadays, to handle concurrency, modern computers contains more cores that bring more computation power. To maximize such hardware architecture, concurrency programming kicked in. Most of the concurrenc...

In today's fast and hyper-complex technological world, High Quality of deliverable Software products is becoming more and more critical. Autonomous cars, Cyber threats and Algo-Trading are an example of areas in which Quality could become critical and in some cases, fatal. While the business is demanding more flexible and continuous ways to deliver Software products the need for new methods and be...

In recent years, deep learning as leading the forefront of machine learning and artificial intelligence. I will give a short introduction to deep learning with historical perspective. Most of the talk will be dedicated to reviewing the latest state-of-the-art examples in image processing, text understanding, and other applications. MP3

Meekan developed apps for iOS and Android, and an Outlook Add-in, and threw them all away to build a chatbot. It was apparently a good move: The scheduling assistant is used in over 10,000 companies worldwide. What happened in the world of chatbots in the last year? What made them so popular? Is it just hype, or is there more to it? We'll go over the benefits of bots over apps, how to make them mo...

This talk is a story about the national Skillz CS competition that involved around 2200 students in the ages of 16-18. In the competition, we invented a game and the students needed to write a program that plays the game. We will talk about how the competition worked, what were the mechanics that drove the students to be so excited and about the technical challenges we had to face MP3
