I have this challenge of converting a bit of html into an image file and then shrinking it into a thumbnail. The shrinking part shouldn''t be too bad, but what advice can you give on converting the html to the image? My thinking is that I will need to convert it to postscript or latex and then convert it to an image from there. Is there an easier / better approach? Michael

I need to show a different background color depending on the type of comment posted. The type of comment is determined from a drop-down selection. I figured the simplest way would be to do something like I have below, but I can''t seem to get it to work: <tr <%= puts ''"style = "background: red;"'' if comment.comment_type == ''Hiring

Hi all I had a fully working samba + ldap PDC. After upgrading from 3.0.7 to 3.0.9 I have lost synchronization of samba password and ldap password.

Hi there I''m going to add microformats in my app. I''ve googled for a while but I can''t find any plugin/gem oriented to the creation and rendering in templates of microformats.

Hi All, I've run into a strange problem, which so far I haven't seen reported by anyone else recently. A while back I set up a Linux box (SUSE 9.2) to authenticate (using kerberos) against a w2k3 AD domain. A nice side effect of this was that I could use "smbclient -k" and save typing in my password again. I didn't have cause to use smbclient for some time, until the other

Hi All, For the past few months I've been running a SUSE 9.2 server here (mostly as an app server) which was a member of an AD domain (w2k3 domain controller.) I used winbind to enable domain members to log into the box, all was well.
