Back-end Development

Cześć! Zapraszamy Was na spotkanie, które odbędzie się **28 stycznia 2026** roku o godzinie **18:00** w **IndieBI, Piotrkowska 157A**, Hi Piotrkowska. Podczas spotkania odbędą się niezwykle ciekawe prezentacje: **1\. Say No to Notebooks \- Magdalena Nowak** Jupyter Notebooks are widely used by data scientists and machine learning engineers. They're easy to use and seem perfect for research focused tasks and are often the first environment for data professionals learning Python. However, their advantages can quite easily become a huge problem as the projects grow and move towards production. In my talk I will share insights based on real challenges I've faced during my years working with data science teams, underlining the disadventages of using notebooks as well as present best practices for transitioning out of the research phase in a smooth way. **2\. Monorepozytoria w Pythonie \- Tomasz Wrona** Monorepozytoria (monorepo) stają się coraz popularniejszym podejściem w świecie Pythona, pozwalającym wygodnie zarządzać wieloma pakietami w jednym repozytorium. Podczas tej prezentacji pokażę nowoczesny sposób na budowę i utrzymanie monorepo w Pythonie z użyciem uv workspaces oraz dodatkowych narzędzi wspierających codzienne zadania. Uczestnicy dowiedzą się, jak jasno rozdzielać zależności, korzystać z jednego lockfile’a i znacząco przyspieszyć CI dzięki równoległemu testowaniu tylko tych pakietów, które faktycznie się zmieniły. Omówione zostaną także techniki tworzenia lżejszych obrazów Dockera i skracania czasu budowania. To praktyczna propozycja dla zespołów, które chcą skalować swoje procesy developerskie, zachowując przejrzystość i szybkie tempo iteracji. Agenda: 18:00 - Rozpoczęcie i sprawy organizacyjne 18:15 - Prezentacja 1 19:00 - Przerwa 19:30 - Prezentacja 2 20:15 - Networking **Zaproś innych!** Powiedz znajomym o tym wydarzeniu i zaproś ich do dołączenia do naszego meetupu oraz na serwer Discord. Razem stworzymy jeszcze większą i silniejszą społeczność! **Śledź nas w mediach społecznych:** ➡️ Oficjalna strona: https://pythonlodz.org ➡️ Meetup: https://www.meetup.com/python-lodz ➡️ Discord: https://discord.gg/jbvWBMufEf ➡️ Facebook: https://www.facebook.com/pythonlodz ➡️ LinkedIn: https://www.linkedin.com/company/python-lodz ➡️ Instagram: https://www.instagram.com/pythonlodz ➡️ YouTube: https://www.youtube.com/@pythonlodz

Zapraszamy na trzy dwudziestopięciominutowe rundy medytacji, w trakcie których będzie okazja doświadczyć swojej pełnej obecności w tym-co-jest z-chwili-na-chwilę. Rundy rozpoczynamy o 18:30, 19:00 i 19:30 - można dołączyć do dowolnej z nich lub odłączyć się w trakcie przerw pomiędzy nimi. Prosimy o przyjście chwilę przed rozpoczęciem rundy, ponieważ startujemy punktualnie. Medytacje odbywają się w każdy czwartek na ul. Zielonej 30 w Łodzi w lokalu HSŁ w głębi bramy. Przy bramie prosimy dzwonić pod numer: 42 203 20 50. Spotkania są otwarte i wszyscy są mile widzani. Jeżeli chcesz zobaczyć, czy medytacja to coś dla Ciebie, temat jakoś z Tobą rezonuje, a może już praktykujesz, przychodź! Zorganizujemy coś, na czym można usiąść, ale dobrze jest wziąć ze sobą swoją poduszkę do siedzenia lub matę. Do zobaczenia!

Rano, przy dobrej kawie i śniadaniu rozpoczynamy dzień ciekawym, startupowpo-technologicznym netoworkingiem. OpenCoffee to regularnie spotkanie w gronie przedsiębiorców technologicznych oraz tych co jeszcze myślą o odpaleniu swojego projektu. Tematy poprzednich spotkań: https://docs.google.com/spreadsheets/d/1MS2IqNQG69guUtcsbFQ3_MByd7fFD2BMX4HfhJah-uA/edit?fbclid=IwY2xjawFfWwlleHRuA2FlbQIxMAABHdzZY8UKMiOa9-vnnDcODnWJJgg3XTeWXIyRKe1tzfIR-_Lyi3pAhhOQNA_aem_jUb8F2hXGuDmukpMHuhVMA&gid=0#gid=0 Proszę wrzucać proponowane tematy na to spotkanie w poście poniżej 🙂. Wygra temat z największą ilością rekacji.

Zapraszamy na kolejne spotkanie planszówkowe! Mamy parę gier w spejsie, ale zachęcam przynieść również własne gry! Chętnie zagramy w coś nowego. Jest też miejsce na zostawienie gier na jakiś czas w spejsie, żeby nie musieć ich targać tutaj co tydzień. \-\-\- Zaczynamy o 19:00, ale warto sprawdzić [https://at.hs-ldz.pl](https://at.hs-ldz.pl) – być może ktoś otworzy siedzibę wcześniej. Jeżeli masz problem z wejściem, zadzwoń na 42-203-20-50 albo wejdź na naszego chata (patrz poniżej). Potrzebujesz więcej informacji? Skontaktuj się z nami na czacie lub mailowo.

## Details \#\# Learn Infrastructure\-as\-Code \(the FUN Way\) — Through Minecraft 🎮☁️ **Joint Meetup: DevOps Columbus - Azure CBUS - Columbus HashiCorp User Group** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint DevOps Columbus, Azure CBUS and Columbus HashiCorp User Group meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. \#\#\# What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time \#\#\# Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way.
