Coub goes to strike
April 10-11, Ulyanovsk will host the largest in the regions of Russia IT conference " Strike ". Coub went to strike last year, could not miss it in this. We will not only be present at it, but we will also bring several reports with us.
')
We will make presentations in 3 sections.
On the first day of the conference, Mikhail Tabunov will tell you what it means to be a good developer:
Mikhail Tabunov , CTO
There are very few qualities that share good and excellent developers, however, the difference in the results of their work is sometimes very large. The point here is not in erudition and some personal qualities, but only in the understanding of values. The developer, they are one, his leadership others. It rarely happens when they coincide. His report will try to explain what we should strive for in the work, and what will be behind it.
Maxim Reshetey , Lead iOS developer
Maxim will talk about how real-time video effects overlay works in the Coub mobile app using OpenGL ES 2.0 with Shaders. With optimization for GPU architecture.
Andrey Kumanyaev , Ruby on Rails developer
A lot of data is great.
Difficult business logic is interesting.
Running fast is great!
Throw out any item - perfect.
I will tell about what happened, how they solved the problems and what they finally came to.
This is the most secret report from us. Come, let's discuss what it is like to roll a large amount of data in PostgreSQL.
And don't forget about the backstage part of the conference, where you can make lots of useful contacts. At the end of the first day you will find a closed afterparty in the company of speakers and colleagues.
