Greg, 1st off, thanx for your great book, and i really hope i find the time to read it
thoroughly. (since i am still stuck somewhere in the middle of "Administration Cookbook" lol!)
Well, people, speaking from the point of the occasional poster and frequent lurker
i can see that smth is going a little bit out of hand in the lists.
I remember my own thread 1-2 weeks ago about NOT IN working much better
in 8.3 than 9.0, how much i was trying to convince people that it was not
FreeBSD related, nor other setting related, trying to convince mladen
that i was not cheating with the explain analyze i posted, trying to answer politely to Tom
who was asking me to post smth that i had already posted 4-5 times till then,
and i can feel the agony of certain members here.
Before i moved the thread from -admin over to -performance i had certain issues at my home's FreeBSD mail server.
Thank God, some reply i wrote one late night on -admin didn't make it to the list.
Anyways, that's open source. Great products, access to source and knowledge at a negligible cost come with a price.
So here is my advice to people in similar situations (me mainly!) : take a deep breath, dont hit the send button unless you are
100% certain you have smth new/positive to say, take some time to do more homework from your part, even try
to read/hack the source, etc...
If this is not possible, then its better to seek for alternatives rather than turning angry.
just my 3 euros!
