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!

**ABSTRACT**
*Mastering Power BI Model Types - Import, DirectQuery, or Composite?* - **Gregor Prohaska**
Whenever you start a new Power BI project, you must choose the right model type — a decision that shapes all the work that follows.
This session explores the world of Power BI model types, focusing on the differences between Import, DirectQuery, and Composite models. We examine the limitations, advantages, and requirements of each model to provide a clear decision guideline for when to use each one.
This session aims Power BI developers, data analysts, BI architects, and anyone interested in maximizing the efficiency and flexibility of their Power BI solutions.
By the end of this session, atttendees will
* know the main differences between Import, DirectQuery and Composit models
* be able to choose (wisely) the right model for a given task
* understand the impact on report design, user experience and governance
If you want to avoid classic model type mishaps, this session is for you. Make your users (and database admins) happy and choose wisely!

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.

Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'!
Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life.
Mission: grow, support, and provide community for atheists in Central Ohio.
Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision.

It was a member of Columbus CoR and held weekly meetings, mostly on Fridays, for several years but then operated as an online only group for some time. In November 2018, Omnipresent Atheists (OA), a group that routinely meets on Tuesdays, invited AoC to merge.

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
