Zapraszamy na kolejne spotkanie JUG 16.11, trochę mięska, trochę na miękko. Tym razem z Daniel Pokusa i Marek Żylicz, będzie o Kubernetes i Konfliktach w zespole: buff.ly/3FRrTob
JUG się spotyka! Sierpień to czas radości wakacyjnej, więc porozmawiajmy o czymś lekkim, jak na przykład- czy maszyny nas zastąpią i wszyscy umszemy z głodu! Jeśli jesteście ciekawi co w czatGPT słychać, okiem programisty, to zapraszamy 2023-08-24: buff.ly/3OKAvkx
I bought a 64 GB pendrive just because it was cheaper than paying for shipping. For someone who remembers how hard it was to get 10th floppy drive, I was just mind blown #I'mOldForSure
Does it mean that the mythical man mop is coming back? edition.cnn.com/uk/live-news/l…
Potencjalnie właśnie byłem ofiarą phishingu, albo @BankMillennium nie umie w marketing. Zadzwoniła Pani przedstawić mi ofertę BM (cold call), ale celem weryfikacji potrzebowała bym podał jej trochę danych. @niebezpiecznik temat do opisania albo klient który b. potrzebuje pomocy
Znajdź wszystkich @pawelpiwosz na obrazku #observability #meetup #JUG @JUGTricity
To nie koniec wakacji jeszcze, więc kto o obserwowaniu Serverless chce posłuchać, a się nie zapisał, ten trąba i niech klika bo to już w czwartek. @pawelpiwosz może nawet z Javy na JUGu skorzysta ;) meetup.com/trojmiasto-jav… Wracamy do Sztuki Wyboru i wracają losowania :)
Meetup 127 @JUGTricity has begun! @pivovarit started from telling us how awesome Hazelcast ... t-shirts are
A reminder of just who he is
