在Github的Issue里面经常见到一堆ACK，原来知道肯定不是TCP的ACK，估计是acknowledge之类的缩写，但是一直不求甚解。

今天心血来潮搜了一下，嗯，猜的也差不多:

• LGTM—looks good to me

• ACK—acknowledgement, i.e. agreed/accepted change

• NACK/NAK —negative acknowledgement, i.e. disagree with change and/or concept

• RFC—request for comments, i.e. I think this is a good idea, lets discuss

• WIP—work in progress, do not merge yet

• AFAIK/AFAICT—as far as I know / can tell

• IIRC—if I recall correctly

• IANAL—“I am not a lawyer”, but I smell licensing issues

像比特币代码仓库里还经常见到:

• Concept ACK—agree with the concept, but haven’t reviewed the changes

• utACK (aka. Untested ACK)—agree with the changes and reviewed them, but didn’t test

• Tested ACK—agree with the changes, reviewed and tested
