I am more or less used to it, for some degree of "used to it", but Erik does have a point. Which is one of the reasons I harp, albeit not continuously about downloading and printing the Integrators manual, which does contain in most cases, quite a bit more detail that the user manual. Sure, you have to clean out that 3 ringer at nominally annual intervals, and print the next one, wasting another small tree. But it sure helps when you need it. But stuff like this current kerfluffle about camview-emc, is STILL hard to find, and is often dated because lots of it assumes you are running 8.04. With any common sense, few if any of use are running from that old an install, although I imagine, somewhere, someplace, someone is still running some version of the BDI, which certainly wasn't usable without breeding a few elephants if you were really brain dead. > On Sun, May 11, 2014 at 3:29 AM, Viesturs Lؤپcis <viesturs.la...@gmail.com>wrote: > > 2014-05-11 5:30 GMT+03:00 Jon Elson <el...@pico-systems.com>: > > > As I understand it, the first net line that creates > > > a signal needs to have an output pin in the list. Yes. In fact, a question? Does the => and <= syntax even work anymore? I ask because I found that the net signalname signal_src signal_target (repeat signal target as needed) net samesignalname more targets syntax mode so much more sense that I haven't used the direction stuffs in 3 or 4 years. > > Not necessarily.

I have to agree. > > Viesturs But I have to also agree that being stuck on 10.04.n LTS is beginning to be a drag, there are later things with 14.04 LTS that we cannot "backport" because suitable libraries simply are not available for 10.04 LTS. So I am waiting with baited breath for a 14.04 LTS based release, which hopefully will not bring in the heartbleed thing since I at least DO make heavy use of the ssh -Y shop or lathe secure logins. The push for that is, I assume, waiting for the 14.04.1 respin?
