Using NLP to Detect Knots in Protein Structures- Eva Klimentová
Proteins are essential components of our bodies, with their function often dependent on their 3D structure. However, uncovering the 3D structure has for a long time been redeemed by months of hard work in the lab. Recent advances in Machine learning and NLP have made it possible to build models (eg. Alphafold) capable of predicting the protein's 3D structure with the same precision as experimental methods.
In this talk, I will explore an even more specific application of language models for proteins - the detection of a knot in a protein's 3D structure solely from the protein amino acid sequence. Knotting in proteins is a phenomenon that can affect their function and stability. Thanks to NLP and interpretation techniques we can try to uncover why and how proteins tie themself into a knot. In this research, we rely on many Python-based tools starting from Biopython to Pymol and Hugging Face transformer library.
Eva is a full-time PhD student in Bioinformatics doing research, teaching and being taught. Currently exploring the world of proteins, their 3D structure and function with a focus on proteins with a knot in their structure and combining it with state-of-the-art Machine learning approaches. In the free time doing anything and everything from dancing, reading, and knitting to reconstructing a flat.

Taming GPT-3 Beast for Media Monitoring
- Petr Šimeček
The emergence of ChatGPT has led to a rapid growth of prospects and implementations in the field of Natural Language Processing (NLP). Various teams were struck with Fear of Missing Out (FOMO) and hastened to incorporate Large Language Models (LLMs) into their products. By using OpenAI models, we successfully integrated LLM into our app on March 2, granting our users the ability to get text summaries of any article. Three weeks later, we trained our own large language model for the same purpose.While heaps of research focus on English texts, this talk will zoom in on using LLMs for smaller languages like Czech or Slovak. I'll share some hair-raising examples from the first days after deployment. I'll also chat about the quirks that come with non-English languages (more tokens, bigger models, ...) and dish about our experiments with various LLMs.
Petr is a biostatistician by training, time series forecaster at Google, currently, entangling knots on protein backbones at Masaryk University and applying large language models at Monitora Media.

Python Vulnerability Management with CVSS- Tomáš Horáček
Do you find it difficult to keep up with the increasing number of reported vulnerabilities? Are you unclear about the severity of a vulnerability in your system? Look no further than the Common Vulnerability Scoring System (CVSS). This standardized framework provides an objective method for scoring security vulnerabilities on a scale from 0 to 10, enabling you to prioritize resources and improve your system's security and resilience. Our talk will demonstrate how to utilize CVSS in Python projects, enabling you to efficiently prioritize efforts and set up automated vulnerability reports. Don't let vulnerabilities go unnoticed - utilize CVSS to enhance your software security today.
Tomas is a Python software developer at Kiwi.com where he works on integrating partner APIs to automate tens of thousands of flight bookings every day. Tomas has prior experience working with Java and Typescript and also has a keen interest in Rust. Tomas is dedicated to writing secure and easy to maintain code. In his free time, he volunteers with the Scouts and enjoys spending his summers at Scout camps, where he can share his knowledge and expertise with younger members.

tmt- Petr Šplíchal
- Miloš Prchlík
The tmt tool provides a user-friendly way to work with tests. You can comfortably create new tests, safely and easily run tests across different environments, review test results, debug test code and enable tests in the CI using a consistent and concise config.
The python module and command-line tool implement the Metadata Specification which allows storing all needed test execution data directly within a git repository. Together with the possibility to reference remote repositories it makes it easy to share test coverage across projects and distros. The Flexible Metadata Format fmf is used to store data in both human and machine readable way close to the source code. Thanks to inheritance and elasticity metadata are organized in the structure efficiently, preventing unnecessary duplication.
Nástroj tmt umožňuje uživatelsky přívětivý způsob práce s testy. Můžete pohodlně vytvářet nové testy, bezpečně a snadno spouštět testy v různých prostředích, analyzovat výsledky testů, ladit testovací kód a spouštět testy v CI pomocí konzistentní a přehledné konfigurace. Modul Pythonu a nástroj příkazového řádku implementují specifikaci metadat, která umožňuje ukládat všechna data potřebná pro spuštění testů přímo v git repozitáři. Spolu s možností odkazovat na vzdálené repozitáře usnadňuje sdílení testů napříč projekty a distribucemi. Flexibilní formát metadat fmf slouží k ukládání dat v lidsky i strojově čitelné podobě, blízko zdrojového kódu. Díky dědičnosti a elasticitě jsou metadata efektivně uspořádána ve struktuře, která zabraňuje zbytečné duplikaci.

Jako již tradičně, klasický termín Pyva vychází v prosinci ne úplně šťastně a proto se sejdeme už 15. 12. od 18h a to v salonku U Dřeváka.
Přednášky nebudou a lightning talky být můžou, ale bez projektoru.
Rádi bychom také po covidové pauze obnovili tradici hardwarového blešáku a burzy samolepek! Máte doma nepoužívaný router, diody, sluchátka, disky, nebo jinou elektroniku? Nebo se nehodil úlovek z předchozích let? Doneste je a vyměňte za něco, co vypadá užitečněji! Máte doma nějaké samolepky, které nechcete? Doneste je a vyměňte za samolepky, které chcete!
Same as previous years, last Thursday in December is not the best date for Pyvo, so let's meet on December 15 at Dřevák Beer & Grill.
No scheduled talks, you can have a lightning talk but without the projector.
We would also like to resume the tradition of the hardware swap market and sticker exchange after the covid hiatus! If you have unused routers, diodes, headphones, disks, or other electronic devices you don't want anymore but can be useful for someone else, bring it and change for something you like better! Do you have any stickers you don't fancy? Bring them and change for some other stickers you like!

Python programátorem pomalou cestou
- Roman Viktor Dvořák
Na posledním Pyvu před prázdninami se podíváme znovu na téma rekvalifikace, tentokrát z trochu jiného pohledu, aneb Python programátorem pomalou cestou. Rekvalifikace, která se nakonec podařila aneb na konci poznáš, jak jsi měl začít.
Roman je původně elektrikář, později prošel řadou relativně krátkých pracovních zkušeností v různých oborech od přímého prodeje služeb až po práci na stavbách. Potom pracoval 5 let v bezpečnostní agentuře a v současnosti je programátorem na volné noze.

Health and monitoring of async Python services
- Max Polezhaev
In our company we’ve got lots of Python services developed using asyncio, which helps us to keep them scalable and maintainable. But with all its benefits the asynchronous approach brings some new challenges. I would like to talk about these challenges and common pitfalls, explain some points requiring attention, such as concurrency control, timeouts, task results, and what metrics can be used to monitor health of async services.
Max is a Senior Software Engineer from the FinTech Tribe at Kiwi.com. See his GitHub: https://github.com/maxpolezhaev

Running processes from Python using asyncio
- Jakub Ružička
I'll talk about my experience with running system processes (commands, scripts) from Python as a packager and automation engineer. Most of the tools I've created, including apkg the cross-distro packaging automation tool, use various system tools through CLI so a robust way to invoke commands is necessary.
Especially, I'll focus on the latest refactor of the apkg command runner to use asyncio.create_subprocess_exec() and asyncio.create_subprocess_shell() functions which allows previously unthinkable - capturing and printing stdout/stderr at the same timeIndeed, after many years of development, Python can finally perform the equivalent of unix tee command available to mankind since the dawn of time.

Automated Network Performance Testing in Python- Ondrej Lichtner
LNST (Linux Network Stack Test) is a Python framework for writing multihost network tests. During the past couple of zears we've redesigned most of the framework so that our tests are now completely written in Python. This allows for a much more dynamic approach to network configuration and design of test procedures. During the presentation we'll show how basic tests can be written and how the same framework is utilized in more complex scenarios where we test the Linux kernel, looking for performance regressions.
Finally we'll shortly discuss how LNST is used at Red Hat with other tools to create an automated pipeline that tests and reports results for kernel and other package candidate builds.
LNST (Linux Network Stack Test) je Python framework pre vývoj distribuovaných sieťových testov. Počas posledných pár rokov projekt presiel veľkým re-designom, vďaka ktorému sú naše testy teraz implementované čisto v Python-e. Toto nám umožňuje veľké množstvo dynamicity a flexibility pri implementácii a návrhu sieťových testov. Prezentácia ukáže základné princípy ako vytvoriť jednoduché testy a ako framework používame pri vytváraní komplexnejších testov zameraných na výkonnostné testovanie sieťového subsystému Linuxu.
Nakoniec sa pozrieme na to ako je LNST zapojené v Red Hat-e do automatizovanej pipeline-y, na testovanie a vyhodnocovanie kandidátnych kernel balíkov.
