- scorpion032 15y agoThat is, half of the files in their perforce are "touched in the last 30 days". I was there, live in this presentation, more than a year ago, at Hyderabad and got this clarification from the speaker.
- nikcub 15y agovery big difference to what the headline says, which was never going to be correct.
- zaph0d 15y agoThe title is a direct quote from the Google Engg. Tools blog post which was on HN recently - http://google-engtools.blogspot.com/2011/12/bug-prediction-at-google.html http://google-engtools.blogspot.com/2011/12/bug-prediction-a...
- scorpion032 15y agoTrue. Half the code can be anything. Half the characters in source, half the lines (Which seem more plausible since version control systems deal with line as a unit) or half of the files or even half the binaries. I'm just clarifying based on my own clarification, which half it is. I don't think, this is any surprising at all. I believe the statistics would remain the same, for many companies.
- markokocic 15y agoMuch more informative that the title itself. Touching file and changing maybe one line is not a big deal, but rewriting half of the source code base every months is.
- lukeholder 15y agowould they merge in head to their build before committing for code review?
- lukesandberg 15y agoSorry misread the original post. Before a code review you don't have to do a sync but its pretty common to sync frequently. I sync constantly as im developing because it's so easy. Occasionally i see reviews where i can tell that the person hasn't sync'd in a while and if i think it matters ill ask them to sync. This usually doesn't happen though
