Code! Code! Code! • Write some code first, something rather than nothing • Beginning new project / shaping new idea is always exciting • Even if your each PR is trivial, it can move OSS project forward ԿΛࠩ͠ஔ͍ͯͱʹ͔͘ίʔυΛॻ͘͜ͱ͕ୈҰɺࣗ Ͱ৽࢝͘͠Ίͯɺখ͞ͳύονͰߏ͍·ͤΜɻ
No Lang Barrier • Japanese Scala developers’ community is so active (especially in Tokyo) • Working only there ironically toughens the language barrier • We should intentionally focus on world- wide activities more than ever ຊޠݍ͚ͩͰ׆ಈ͍͚ͯ͠·ͤΜɻݴޠͷนΛͭͬ͘ ͯ͠·͍·͢ɻ
