Why It’s Worth Going

  • Talk in person

    To see old friends. To discuss current problems. To come up with new ideas. To debate and just chat.
  • Switch the format to offline

    To have a change of scenery, to distract and have a good time. To gain fresh impressions and new acquaintances.


There will be a broadcast on the Offline day of the conference, which is available to participants with any ticket. If you want to meet and interact with the speakers and other participants live,we are waiting for you at the venue. And if you are not ready to get to the venue, recordings of all the talks and activities will be waiting for you on this website.


  • The time in the program is for the time zone UTC+3.

  • As offline day comes closer, the program may be updated.

      E2E testing in CI with Testcontainers

      The speaker will tell you what E2E-tests are, how they differ from unit and integration tests and why they are an integral part of the release cycle in microservice products. Using a concrete example you will see how to write your E2E-tests in JUnit5 + Spring Boot Test and set up their automatic launching for each pool-request using Testcontainers.

      Adding scripting language support to AFL and LibFuzzer with Lua as an example

      One component of Tarantool is a Lua application server, which provides Lua API to the DBMS itself and four dozens of auxiliary modules. Until now, functionality testing with Lua has been limited to example-based testing. Randomized testing has been limited due to the lack of Lua support in fuzzers. The speaker implemented support for phasing Lua scripts in the popular American Fuzzy Lop and libFuzzer engines, which allowed finding problems that other tests did not find. 

      The talk will be of interest to anyone who develops server software, is interested in randomized testing, or plans to add support for a new language in AFL or libFuzzer. Knowledge of Lua will not be required.

      Security analysis of Windows applications

      Информационная безопасность — это один из важнейших компонентов в любой организации, так как несанкционированный доступ к информации может привести не только к материальным потерям, но и к полному краху компании. Чтобы избежать этого, нужно проводить анализ защищенности информационных систем. Один из самых действенных способов такого анализа — тестирование на проникновение.

      В докладе спикер познакомит вас с некоторыми методами тестирования на проникновение и их применением для анализа защищенности Windows-приложений, что позволит не допустить превращения разрабатываемых вами приложений в оружие злоумышленника.

    The incidence of COVID-19 is increasing and we want to ensure sufficient security measures at the Offline day. For this reason, we are introducing new rules for visiting the site. At the entrance, we will ask you to show a PCR negative result test made 48 hours before the event.

    We consider vaccination an insufficient safety measure to avoid an outbreak of the virus. Therefore, you won’t be able to access the Offline day only with a QR code. We ask you to take care of others’ and your own safety, and do a PCR test before the conference.

    If you have problems getting to the site, email our support — we will help you.

    • How can I access the conference?
      Show your PCR test with a negative result (it’s valid for 48 hours). Without a PCR test, even if you have a QR code, we are sorry, but you cannot attend the offline day.
    • I have a vaccination certificate. Can I attend the conference?
      If you have a QR code without a PCR test with a negative result (it’s valid for 48 hours), you will not be able to access the conference.
    • What if I have bought an offline ticket? Will I be refunded?

      You will be refunded if none of these options suits you:

    • Offline was so long ago that I no longer remember what the procedure was for offline conferences.
      Don’t worry, before the conference we will send you a participant’s memo. It will contain all the necessary information.
    • Can I buy a ticket only for the Offline day of the conference?
      To attend the Offline Day, you must purchase an "Online+Offline" ticket. It entitles you to attend the offline day of the conference and access to the recordings of the online day.
    • How do I get into Offline Day if I have a "Double Online" ticket?
      If you already have a ticket for the online part of the conference, you can upgrade it to "Online+Offline". To do so, email our support team at
    • How do I get to the Offline day if the company only paid for my "Double Online" ticket?
      If the company that paid for your ticket is not willing to upgrade to Offline, you can do it yourself at a discount. The discount is given for taking the survey after the online part of the conference ends.
    • Is there a limit to the number of tickets for the Offline day?

      The number of tickets is limited to the capacity of the conference venue.

      So it is better to buy tickets in advance while they are available.

    • Are there any restrictions on going to an offline conference?

      In order to access the conference, you will need a negative PCR test. It must have been done no earlier than 48 hours before registration.

      If you have a QR code but no PCR test with a negative result, you will not be able to access the conference. A valid PCR test is a prerequisite for attending the conference.

      If you have problems getting to the site, email our support — we will help you.

    • What will be the case with Offline Day if a new wave of COVID-19?

      The incidence of COVID-19 is increasing, so we are setting new rules for visiting offline sites.

      In order to get to the Offline day of the conference, we will ask you to present a PCR test with a negative result made during the 48 hours before the event. At venues in Moscow and St. Petersburg, we will provide seating according to the principles of social distancing. These are tough measures, but they will make conference participants safe.

      If the situation worsens and offline events are canceled, we will move the Offline Day to online. That way, speakers will give their talks remotely or from our studio. Nothing will change for participants with a "Double Online" ticket. "Online + Offline" participants can convert their ticket into a "Double Online" ticket with a refund of the price difference, or carry it over to the next year. It will also be possible to return the ticket and get a full refund.

      Either way, we will not be postponing the conferences to next year.
