Re: [TUHS] Unix stories

It's simply a lack of craftsmen level thinking. Managers think that people are fungable, whatever that means, I think it means anyone can do this work. That's simply not the case, some people get the big picture and the details and some people don't. There is also a culture of the cool kids vs the not cool kids. For example, at Sun, the kernel group was the top of the heap. When I was doing nselite which begat Teamware then BitKeeper then Git et al, I was in the kernel group. They wanted me to go over to the tools group. I looked over there and saw people that weren't as good as the kernel people and passed. Same thing with testing. So many bad test harnesses. Because testing isn't respected so they get the crappy programmers. One of the best things I did at BitKeeper was to put testing on the same level as the code and the documentation. As a result, we have a kick ass testing harness. Here's a sample t.file in our test harness: echo $N Check that component rename is blocked ......................$NL nested product cd "$HERE/product" bk mv gcc gccN 2>ERR && fail -f ERR cat <<EOF >WANT mvdir: gcc is a component Component renaming is unsupported in this release EOF cmpfiles WANT ERR echo OK The harness, which is all open source under the apache license at bitkeeper.org, let's you write tiny shell scripts, they either echo OK (pass), (bug) (pass but not really), or anything else and they fail. The harness allows for parallel runs. In the early days we ran the tests in alpha order, later we got a huge speed up by running them in most recently modified order (fastest time to failure). All of that is the result of me (semi good, setting it up) and Wayne Scott (crazy good, he made it work in parallel and bunch of other improvements) being the guys who worked on it. We're $250K/year people on average. On Mon, Jan 02, 2017 at 11:23:47PM +0000, Tim Bradshaw wrote: -- --- Larry McVoy lm at mcvoy.com http://www.mcvoy.com/lm
