[Izhevsk and Perm, Announcement] Warm and transistor online broadcast CodeFest X

This weekend, Contour is hosting an online broadcast of the CodeFest X jubilee conference in Perm and Izhevsk. It seems that this is the largest conference for developers beyond the Urals. At the conference in Novosibirsk there will be 10 sections with reports and 3000 participants.

In Izhevsk we broadcast the section Backend. Registration for broadcast .
In Perm - sections Backend, Frontend and QA. Registration for broadcast .

Come see and discuss the reports in a pleasant company.

CodeFest X is a good program. Our Grisha Koshelev gnkoshelev will talk about the Apache Kafka architecture and its use in the open source project East :

Have you tried Kafka?

Apache Kafka is a distributed messaging software broker used in real-time processing of large data volumes. The distinctive features of Apache Kafka include: reliability, scalability and high performance. In the report we will analyze the main architectural features and scenarios for using Apache Kafka. Consider the unobvious moments and rakes that we have collected on the way of the East.

Lesha Kirpichnikov BeeVee will tell you how to write postmortems and learn from your mistakes:

Accidents help to learn
')
Over the last three years, about 1000 fakaps of varying degrees of epicity have occurred in Contour. Among them, for example, 36% were caused by rolling out a low-quality release into production, and 14% were caused by maintenance work on iron in the data center.

How do I know all this? From the archive of reports that we call post-artema. Postmortems are written by engineers on duty who responded to the notification of the accident and were the first to begin to understand its causes.

Why does our team need this archive? Why do we force an engineer who has been repairing a complex system for several hours without having to write a few pages of text about it? This knowledge helps us move infrastructure development in the right direction. What do you need to do right now - to improve the system of collecting metrics or to select admin rights on the servers from the developers? What will be more useful - a new tool for load testing or the introduction of canary deployment?

In the report, I will talk about how to write a useful post-mortem: who should write it, what it is necessary to mention and how to implement this complex DevOps practice in a large company, where a few years ago no one ever heard of any post-mortem. Let's sort out a couple of examples of real fakaps - admit it, you like to listen to stories about how someone screwed up :)


Lyosha speaks at CodeFest 2018 .

Dima Yakin will explain how testing of “smart hardware” differs from testing of familiar web applications:

Testing the Cash Iron. Battle for the future

Big Brother is watching you and this is no longer the delirium of a madman ... Entrepreneurs of all networks and even your favorite store transmit information about your purchases directly to Big Brother via online ticket offices! Hundreds of thousands of stores across the country collect statistics about our purchases every second and the Government knows that you will eat for dinner in 5 seconds.

I will tell you how cash register software is being tested, where we started to learn the tacky field of online cash registers, what tasks we faced, and also to open the curtain, what happens in reality when you come to buy “dumplings with mayonnaise” in the store.

2027 year of our era. Cash Machines rose from the ashes of a check tape. Their war aimed at combating tax evasion has lasted for a decade, but the decisive clash is not in the future. Here. Today. Nowadays…
