Tatry IT Ťa pozýva na pravidelné stretnutie o aktuálnych a zaujímavých (nie len) digitálnych a IT témach. Eventy organizujeme v spolupráci s [Coworking Poprad](https://coworkingpoprad.sk). Príď na meetup Tatry IT Community na tému Salesforce. Salesforce si veľa ľudí spája najmä s obchodom, no v praxi ide o oveľa širšiu platformu. V tejto prezentácii ukážem, čo Salesforce vlastne je, kde sa používa, aké typy procesov na ňom firmy stavajú a prečo je zaujímavý aj pre ľudí mimo Salesforce sveta. Pridám aj svoj vlastný príbeh, krátky pohľad do prostredia Tourlane a na záver spomeniem aj nonprofit oblasť, kde Salesforce ponúka oprávneným organizáciám licencie zdarma. \ **Speaker: Karol** Zaregistruj sa [tu](https://docs.google.com/forms/d/e/1FAIpQLSdZALAk-Kau7oEudSai555Ut7vDRroJlB1WqFri9DkdxnqCSA/viewform?usp=publish-editor).

Through a series of benchmarks, we'll observe mutex behavior under increasing contention and across different core counts to see both modes in action. 9:05 PM: Networking Networking over drinks and food *** Hosted By Natalie Pistunovich, Organizer Ole Bulbuk, Organizer Tim Scheuermann, Organizer Anderson Queiroz, Organizer Complete your event RSVP here: https://gdg.community.dev/events/details/google-gdg-berlin-golang-presents-hybrid-april-golang-meetup-2/.

AI is changing how art is made. But when does it stop being your work and start being the machine’s?
