Together with other attendants, we managed to push more 6 PRs in less than 8 hours and fix a lot more packages (due to a fix of  `openjfx` by our site reliability engineer Alexander Bantyev).

## Need help? 

If you or your company need tips on how to more effectively move to remote work, we offer free consultations. [Send us an email](https://serokell.io/contacts), and we will try to help the best we can. 

In addition, we have compiled a few tips and guidelines in our remote work survival blog posts [here](https://serokell.io/blog/survive-remote-work) and [here](https://serokell.io/blog/surving-remote-work).

In the interview, Arseniy Seroka talks about Serokell's mission and the past and present of the company. He also shares his view on the software engineering future and reveals the main fields Serokell is working on these days.

Serokell CEO Arseniy Seroka Gave an Interview to Website Planet

> Serokell’s mission is to make great things happen. We aren’t afraid of challenges; we welcome them. And we work hard to improve at every step of the way, be it coding, recruitment, communication.

Our CEO Arseniy Seroka was recently interviewed by Website Planet, one of the leading content portals and review centres for those who want to build a new website or improve an existing one.

In the interview, Arseniy talks about the story of the company, its unique features, and the mission of Serokell. He points out that we all in the company work to make great things happen and improve with every step. Another significant mission of Serokell, says our CEO, is to support talented young scientists and give them the space and environment to work on outstanding projects.

To fulfil this mission, Serokell also acts as a sponsor of various contests and events. For example, our company supports the computer laboratory based at the ITMO university along with such companies as JetBrains, Yandex, Mail.ru Group, and Tinkoff.

Arseniy also shares his view on how he anticipates the future of software engineering. He believes that new stunning technologies will keep appearing, which means more talented people will use them to build products and services that change the world.

Serokell at AiML 2020

Advances in Modal Logic is one of the most popular conferences on modal logic. Read about the conference and Danya Rogozin's participation in it.

[Advances in Modal Logic](http://www.aiml.net) is one of the most popular conferences on modal logic. AiML covers the whole landscape of modal logic and its current state of affairs. Topics are not restricted to only abstract questions of modal logic but also includes the aspects related to artificial intelligence, philosophy, topology, algebra, etc. This year, the conference was online due to the pandemic – the University of Helsinki did a great job in organising it via Zoom.

## AiML talks

The AiML talks were split into three categories. The first category was plenary talks. This year, invited speakers were Bahareh Afshari (the University of Amsterdam), Nick Bezhanishvili (the University of Amsterdam), Melvin Fitting (City University of New York), and Nina Gierasimczuk (Technical University of Denmark), all great talks indeed. 

Out of those, I would like to emphasise the talk by Nick Bezhanishvili called ‘Filtrations, Canonical Formulas, and Axiomatisations of Superintuitionistic and Modal Logics’. The talk was quite close to my current research on model-theoretic aspects of Boolean algebras with operators.
 
There were also talks based on full papers. Topics of those papers represent a variety of trends in modal logic that include technical, applied, philosophical, and historical problems. Moreover, this conference is my debut as a paper reviewer. One of the accepted papers has been approved by myself as well.

## My presentation 

My talk was the short one and is based on a short five-page abstract. It's called ‘Canonical extensions for the distributive full Lambek calculus with modal operators’. 

Briefly, this talk provides an algebraic approach for Stone-style representation for bounded distributive lattices with modal operators to characterise the class of canonical logics. Canonical logics, in their turn, are adequate with respect to relational Kripke semantics if their algebras ‘respect’ such an algebraic representation called canonical extension. The result of this talk extends some of the results by [Mai Gehrke, Yde Venema, and Hideo Nagahashi](https://www.sciencedirect.com/science/article/pii/S0168007204000880).
