Subject RE: Version resolution question
Date Sat, 07 Dec 2013 01:02:13 GMT
No it isn't a good thing. I never said it was. However I am trying to make a case for upgrading
and in order to do that I need to test against all of our code in a sandbox environment. I
am having issues building and was hoping to have those resolved. :)

Subject: Re: Version resolution question

I took a quick visit to your web site and I can see why security and stability trumps innovation.

I am not sure how working around the corporate security regime would be a good thing.

Sometimes you just have to honour the trade-offs that management makes and let them pay for
them.

If your projects take longer and get blocked, you just have to down tools and wait (preferably
in an executive office) until the decisions and testing get finished.

Good luck.
Ron
