More and more Rails developers are finding out that deploying a Rails application isn’t as simple as upload and rename; Rails apps work best when running all the time, and many Rails programmers are moving from traditional, shared hosts, like Dreamhost, to virtual private servers, like Rimuhosting, which allow them full control (and responsibility) of production servers.

Learning .NET Regular Expressions with Expresso
Did you ever wonder what Regular Expressions are all about and want to gain a basic understanding quickly? My goal is to get you up and running with a basic understanding of regular expressions within 30 minutes. The reality is that regular expressions aren’t as complex as they look. The best way to learn is to start writing and experimenting. After your first half hour, you should know a few of the basic constructs and be able to design and use regular expressions in your programs or web pages. For those of you who get hooked, there are many excellent resources available to further your education.
What the Heck is a Regular Expression Anyway?

Searching Files on UNIX
On MPE you can display files
using the :Print command, Fcopy, Magnet,
or Qedit (with pattern
match searches). On HP-UX
you can display files using cat and even better using
more (and string search using the slash “/” command), and
Qedit (including searches of $Include files, and so on),
but if you really want to search for patterns of text
like a UNIX guru, grep is the tool for you.

Ok so I had to compile PostgreSQL at work and installed the most recent one. 8.2.5 and compiled it with perl, ssl support
I followed the instructions on the install file. I then created a postgres user and initialized the db and also
installed tsearch2 and ltree
everything worked fine except that when importing the data I got a few errors related to tsearch2 there is function that the new tsearch2 that is on 8.2.5 is missing so data from our backup can’t b e imported because that function does not exist.
So basically this is something the developers have to figure out if they want to stay with the old version of postgres or upgrade to the new version and still get the errors of the new tsearch2
Things I had to do copy a init.d/ script to start the db automatically the script was inside the /contrib/start-scripts folder then I copied the script and put it inside my /etc/init.d/ folder and changed permissions to execute and then I used chkconfig to make it start.
I also had to add paths to my /etc/profile so that the shell can find the path to the psql binaries and other cool tools.
I guess that is basically what I had to do to upgrade to the new postgres.
There wasn’t anything else special that I had to go , Oh I remember I had to install readline-devel because the .configure script was complaining that I didn’t have readline installed. I had the readline RPM installed but the configure script was looking for files included only on the readline-devel
so I did a yum install redline-devel

I haven’t seen a lot of talk about this problem, but as I have seen the question pop-up recently among even some well-known postgresql users, I thought maybe I ought to write some notes to help out future generations and all that. Basically it all revovles around the following errors when upgrading an 8.1 system with tsearch2 into an 8.2 system.
