Open SysConf 2022 Уже в Октябре!
 
Привет, мы готовим новую - четвертую ежегодную встречу Open SysConf'22.

Уже точно есть:
— Три доклада
— Собрано половина бюджета
— Место, дата и время встречи
- Обновленный сайт sysconf.io

Обычно у большинства людей обстоятельства складываются таким образом, что вечно что-то мешает заняться спортом, сделать доклад, поучаствовать в конфе, мешают обычно работа, откладывание за завтра и тп и тд...

Собраться, поделиться знаниями, найти время для себя - это то, что нужно действительно сделать здесь и сейчас (и в Октябре)! Расправь плечи дорогой друг, подними голову и ступай смело вперед:

- https://sysconf.io
- 14 Октября, с 11:00 до 20:00, Алматы.

Зал большой, места хватит всем! Все нужные ссылки, ты найдешь на сайте. Peace ✌️.
