how do developers deal with the pervasive feeling that the stuff they wrote is so fragile.. even when that's proven wrong by actual production use
@f0x Lots and lots and lots of unit tests. Reproduced a bug? Write a test, ensure it does not come back. Then after a while, trust is built you can sleep well at night
@f0x personally i'm just like 'fuck it! fuck!' and so on and so forth, it helps
