Zen w Hackierspejsie
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!

Flutter Łódź - 19 lutego 2026 - Claude Code & Jak stworzyć buttona bez Materiala
*💪 Flutter Łódź to grupa dla osób, które tworzą we Flutterze lub chcą bliżej poznać ten framework. Niezależnie od tego czy masz już bogate doświadczenie, robisz apki mobilne czy webowe, pracujesz w software house czy masz własny produkt. Każdy powód jest dobry by się spotkać, poszerzyć horyzonty i dowiedzieć się czegoś nowego o Flutterze!*
Najbliższe spotkanie już **w czwartek** **19 lutego 2026** godzina **18:00** 🚀
🚨 Uwaga zmiana lokalizacji 🚨
Spotykamy się w **Starej Drukarni**, **Gdańska 130**
👉👉👉 **AGENDA** 👈👈👈
👉 **18:00 Marcin Szałek - Claude Code 101**
O nim: Flutter developer od 2017. Początkowo freelancer, obecnie Flutter dev w brytyjskim startupie Cheddar. Lubi ładne designy, czysty kod, i delegowanie jak najwięcej do LLMów.
Prezentacja: Coraz więcej programistów przechodzi z pisania kodu na rzecz generowania go za pomocą AI. Jednym z narzędzi to umożliwiających jest Claude Code, którego od pół roku jestem wielkim fanem. W prezentacji omówimy czym jest, a czym nie jest Claude Code, omówimy Skille, Sub-agentów, Hooki, Commandy, pluginy, context management i wiele innych rzeczy, o których warto wiedzieć przy używaniu CC.
👉 **19:00 Albert Wolszon** **-** **Jak stworzyć buttona gdybyśmy nie mieli Materiala (albo Cupertino)**
O nim: Flutter GDE. Flutter developer od czasów Fluttera 1.0.0. Najbardziej lubi developować UI i aspekty związane z internacjonalizacją. Odpowiedzialny za tworzenie design systemów LeanCode i kilku dużych klientów. Twórca TMSa dedykowanego Flutterowi. Po pracy lata jako prywatny pilot.
Prezentacja: Korzystając z komponentów dostarczanych przez framework, często nie zwracamy uwagi na niektóre ich istotne elementy, które sprawiają, że są naprawdę godne produkcyjnej apki. W tej prelekcji przejdę przez proces tworzenia prostego buttona we Flutterze, używając wyłącznie najbardziej prymitywnych widgetów, bez korzystania z Materiala, ani Cupertino, jednocześnie dbając, by button pozostał w pełni użyteczny i dostępny.
**🍕20:00 - Pizza i napoje do umilenia rozmów! 🍕**
👉👉👉 **CALL FOR PAPERS** 👈👈👈
Chciałbyś wystąpić na tym lub innym wydarzeniu? Chciałbyś się podzielić swoimi doświadczeniami z Flutterem? Daj nam znać!!! Mamy stale otwarte Call for papers i z przyjmnością Cię wysłuchamy! Formularz zgłoszeniowy: [https://form.typeform.com/to/sNteWH6v](https://form.typeform.com/to/sNteWH6v)

### Review
Praise for Quanta and Fields:
“Readers will be electrified by his discussion of wave functions, entanglement, fields, and so much more. From the most infinitesimal of subatomic particles to the seemingly vast infinities of the universe’s great expanse, Carroll’s latest inquiry illuminates, well, everything.” —Booklist
"In that void between hand-wavy popular science and academic textbook, this modern, informative and engaging account of quantum physics ticks all the boxes. Carroll the Explainer at his very best." —Jim Al-Khalili

An Easy Intro to Feynman's Quantum ElectroDynamics (QED)
Title: An Easy Intro to Feynman's Quantum ElectroDynamics (QED)
Summary: One of the most delightful and informative physics books ever written is Richard Feynman’s QED. In this short book, Feynman undertook the daunting task of explaining his Nobel-Prize-winning theory, Quantum ElectroDynamics, without any math except in a few elaborating footnotes. Remarkably, he succeeds! In this talk, Terry replicates many of his arguments to show how you, too, can understand one of the most fundamental mechanisms of physical reality by using not much more than lots of tiny one-hand clock dials moving through space.

Design of a Quantum Photonic Full Adder Gate based on an Integrated Circuit
Title : Design of a Quantum Photonic Full Adder Gate based on an 8-mode Integrated Optical Circuit
Date: Feb 28 2026 Noon - 14:00 EST
Abstract: Multiport interferometers designed using the Clements decomposition algorithm can be used to implement compact quantum-photonic full-adder (FA) gates on photonic integrated circuits (PICs). By expressing each element of the FA gate matrix in terms of the permanent of a non-unitary matrix, enabled through Boson sampling, the required number of MZIs in the gate can be further reduced. In this presentation, we will discuss the design of an FA gate modeled as a four-photon scattering process on an eight-mode integrated optical circuit, where the permanents of submatrices determine the output probabilities. Simulation results demonstrate a fidelity of 1 and a success probability of 2.22 × 10⁻⁴ for the FA gate. We will also examine the impact of phase-shifter and attenuator variations on fidelity and success probability using Ansys Q-Interconnect software. Finally, we will compare the performance of the proposed FA gate with a benchmark Toffoli gate designed using the same approach.
Speaker: Shafiqul Hai received the B.Sc. degree in Electrical and Electronic Engineering from the Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh, in 2007, and the M.Eng. (Thesis) and Ph.D. degrees in Electrical Engineering from McGill University, Montreal, QC, Canada, in 2011 and 2016, respectively. He is currently an Assistant Professor in the Department of Electrical and Computer Engineering at Lakehead University. His research interests include the modeling and characterization of compact nanophotonic devices and components for next-generation optical fiber and RF communication systems, as well as quantum computing on photonic integrated circuits. He is the author or coauthor of more than 12 peer-reviewed journal papers and 15 conference publications.
Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation ([https://www.qaif.org/](https://www.qaif.org/)) ,
Dr. Sebastian Zajac , member of QPoland ([https://qworld.net/qpoland/](https://qworld.net/qpoland/))
