Advocating the FORCING of https is IMHO utterly ridiculous for the reasons I pointed out. Today you CAN use https with svn if you wish.=C2=A0 You are not *forced* = to.=C2=A0 There are good reasons not to, including caching.=C2=A0 The problem with = not knowing if what you got is authentic and not tampered with is simply not resolved by forcing https; it's an out-of-scope hack that fails to target the actual issue. A forced election of something that doesn't actually solve the problem is IMHO a political argument rather than a technical one.=C2=A0 The issue= of potentially-tampered-with source code not only can't be dealt with correctly through the use of https (at least not with the public CA infrastructure that "everyone" relies on for "pedestrian" https) there ARE other means of dealing with it correctly that do not require using https. That's where attention should be focused. --=20 Karl Denninger karl@denninger.net <mailto:karl@denninger.net> /The Market Ticker/ /[S/MIME encrypted email preferred]/
