@rf у кого есть опыт использования BSD систем на десктопе, расскажите про свой опыт, с какими проблемами столкнулись, в чём отличия от использования GNU/Linux?

Какой ваш любимый шрифт?

Как относитесь к тивоизации?
Корпорациям тоже нужна свобода, или все устройства должны выполнять то, что хочет их владелец?

Вот сижу и думаю, а почему под С существует только 2 нативных тулкита: EFL да GTK. Причём EFL полуживой, огромные проблемы с документацией не решаются годами. Где-же огромный выбор, как обычно бывает в оупенсорсе?

Поиграл сегодня в SuperTuxKart. Саундтрек классный. Сложность "Любитель" слишком лёгкая, сложность "Эксперт" на любителя

То чувство, когда ты всего-лишь не правильно поставил стрелочки, а компилятор такой:

Подскажет кто-нибудь тулкиты с поддержкой Wayland под С++, альтернативные Qt и GTK?
