Last Friday, some of Serokellers participated in a hackathon in Moscow. Read about the hackathon and their experience in the article.

Serokell at ZHF Hackathon

Last Friday, some of Serokellers participated in a semi-physical [Zero Hydra Failure Hackathon](https://nixhax.github.io/zhf-21.11/index.en.html) in [undefspace](https://undef.club/#about), Moscow.

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).

ITMO Interviews Arseniy Seroka

Our CEO Arseniy Seroka has recently been interviewed by one of our partners, ITMO. In the interview, he speaks about science, Haskell, and working remotely.

Serokell at ZuriHac 2021

Last weekend, we participated in ZuriHac 2021. Read more about our participation and talks presented in this article.

Last weekend, we participated in [ZuriHac 2021](https://zfoh.ch/zurihac2021/).

ZuriHac is the the biggest Haskell hackathon in the world – an event gathering together Haskellers from all around the world to hack on various community projects. This year, it was run online, and we were proud to be one of the sponsors. 

Our track consisted of two talks. 

## Dependency Analysis of Haskell Declarations

In our first talk of the day, Artem Kuznetsov from our GHC team presented a talk on dependency analysis in GHC. He explored how GHC analyzes Haskell code to type-check it in the correct order, showed the flaws of the current implementation, and took a look at  what a future algorithm might look like.

## How to Make the Most out of Servant

In the second talk of the day, our former employee and friend Maxim Koltsov presented [servant-util](https://github.com/serokell/servant-util), a collection of batteries for Servant – the most popular web framework in Haskell. He demonstrated how to add sorting, filtering, pagination and more to your API in practically no time, along with optional DB integration via Beam.

Fake News Detection With Machine Learning

Join us on 29th April at 16:00 UTC to learn how you can detect fake news with the help of machine learning.

Join us on 29th April at 16:00 UTC to learn how you can detect fake news with the help of machine learning. 

Our data science team lead Ivan Markov will give an exciting overview of fake news detection approaches. The talk will cover the history of fake news and show techniques to detect them using machine learning algorithms with real-world cases and examples.

He’ll cover both conventional techniques and state-of-the-art deep learning methods implemented by the biggest players in the field of AI and NLP.

If that is a topic you’re interested in, you can add it to your calendar [here](https://serokell.io/academy#participate).
