Gone wild

Learn how to do GUI programming in Haskell with GTK+.

Introduction to GUI Programming in Haskell

**Update:** You can watch the full talk on [YouTube](https://www.youtube.com/watch?v=k1aq8ikO-8Q&t=2s).

Join us on 1st October, 17.00 UTC to learn more about GUI programming in Haskell. 

Our software engineer Vladislav Zavialov will give a talk on how to use Haskell and GTK+ to build graphical user interfaces in a functional programming language. He will talk about topics such as:

*   Initializing the build environment with Nix.
*   Creating an app using GTK+ widgets. 
*   Offloading work to other threads, using `GLib.idleAdd`. 
*   Documentation and resources to study if you want to build an app of your own.

This is a great way to get started with GUI development in Haskell and find answers to any questions you have. 

To watch the talk, [join us](http://meet.google.com/fui-diin-uxk) on 1st October, 17.00 UTC.

By the way, if you haven’t yet seen our previous talk by Maxim Koltsov, we highly suggest checking it out. In it, Maxim goes over how evaluation and GC in Haskell work, going deep in the compilation pipeline of Haskell, showing some interesting details of intermediate languages that GHC uses, and giving tips to optimize GC in Haskell.

#SerokellChat on April 28th!

Serokell will be hosting its first-ever Twitter chat on Tuesday, 28th, at 2 PM GMT.

Serokell will be hosting its first-ever Twitter chat on 28th April at 2 PM GMT. 

Our first special guest will be Serokell CTO Kirill Elagin, answering questions about the benefits of Haskell and how to grow as a Haskeller. If you are in the beginning or middle of your Haskell journey, this is an excellent opportunity to ask questions on things you should master to become a top-tier Haskell developer (and land a job at Serokell 😉).

![Twitter chat](/files/0n/0nt6pk7a.222_(2).jpg " ")

## What is a Twitter chat? 

It’s quite simple. Join us at the [#SerokellChat](https://twitter.com/search?q=%23serokellchat) hashtag next Tuesday from 2 PM–3 PM GMT, and participate in a discussion about Haskell with other Haskell enthusiasts and Serokell employees that work on actual production grade Haskell code. 

We will post 6 questions to start off the discussion, and you are welcome to express your opinion (which we highly value!) on these topics and discuss them with our special guest. 

Book the time in your calendars, follow us on [Twitter](https://twitter.com/serokell), and see you at #SerokellChat!

Serokell Offers Free Consultations

During these times, we believe it is our duty to help others. Therefore, Serokell conducts hour-long audits and consultations for free for those in need.

During these times, we believe it is our duty to help others. In particular, small and medium-sized businesses because those are the ones most vulnerable right now.  

Therefore, [Serokell](https://serokell.io/fintech-development) will conduct hour-long audits and consultations for free for those in need. 

**How we can be useful right now:**

*   We can help you with the transition to remote work, provide a list of tools and instructions on how to use them.
*   We can analyze your business and tell you about the processes you should prioritize digitalizing.

This is not a hidden sales tactic that will end up with “if you want to learn more, order our consulting services”. What it is, is an hour-long consultation (or audit) from one of our executives that will result in a list of things to do and directions to pursue. After that, it is your decision on whether and how to proceed.

**Dates**

We cannot promise to get back to you “tomorrow”, as this is something we are doing in addition to our usual work with our customers, but we will try to free as much time as we can. 

**How to apply**

Leave a comment below or write to us: [hi@serokell.io](mailto:hi@serokell.io). After that, we will contact you in the next few days with clarifying questions and tentative dates. If we understand that we can’t adequately help you in the situation you are in, we will say so.  

<br>

Right now, we can process about 10 applications. Our customers, obviously, will still be a priority for us as we are already working overtime to answer their questions and needs. 

We wish everyone the best of luck in tackling the crisis. It will require hard work, but we will persevere.

Serokell at NixCon 2020

On October 16-18, we participated in NixCon 2020. Here's the details of our participation.

On October 16-18, we participated in NixCon 2020. 

NixCon is an annual conference for contributors and users of [Nix](https://serokell.io/blog/what-is-nix) and NixOS. 

It’s an event we keep participating in every year, [including the previous one](https://serokell.io/blog/serokell-nixcon2019). This year, due to the COVID crisis, it was done remotely. 

One of our employees, Alexander Bantyev, participated with a talk on Nix flakes in production, a thing we have been working for some time now. 

If you’re interested, here’s the talk. You can also see all the other talks of the event on their YouTube channel.
